Ain't Just Imagination! Effects of Motor Imagery Training on Strength and Power Performance of Athletes during Detraining.

This study aimed to investigate the effects of motor imagery (MI) training on strength and power performances of professional athletes during a period of detraining caused by the COVID-19 outbreak. Thirty male professional basketball players (age, 26.1 ± 6.2 yr) were randomly assigned to three counterbalanced groups: two MI training groups, who completed imagery training by mentally rehearsing upper and lower limb resistance training exercises loaded with either 85% of one repetition maximum (85%1RM) or optimum power loads (OPL), or a control group. For six consecutive weeks, although all groups completed two weekly sessions of high-intensity running, only the MI groups performed three additional MI sessions a week. Maximal strength and power output were measured through 1RM and OPL assessments in the back squat and bench press exercises with a linear positioning transducer. Vertical jump and throwing capabilities were assessed with the countermovement jump and the seated medicine ball throw tests, respectively. Kinesthetic and visual imagery questionnaires, and chronometry and rating of perceived effort scores were collected to evaluate MI vividness, MI ability, and perceived effort. Physical performances improved significantly following both MI protocols (range, ~2% to ~9%), but were reduced in the control group, compared with preintervention (P ≤ 0.016). Moreover, interactions (time-protocol) were identified between the two MI groups (P ≤ 0.001). Whereas the 85%1RM led to greater effects on maximal strength measures than the OPL, the latter induced superior responses on measures of lower limb power. These findings were mirrored by corresponding cognitive and psychophysiological responses. During periods of forced detraining, MI practice seems to be a viable tool to maintain and increase physical performance capacity among professional athletes.

Neurophysiological evidence of motor imagery training in Parkinson’s disease: a case series study

AbstractBackground:Motor imagery (MI) has become an increasingly popular rehabilitation tool for individuals with motor impairments. However, it has been proposed that individuals with Parkinson’s Disease (PKD) may not benefit from MI due to impairments in motor learning.Objective:This case series study investigated the effects of a 4-week MI training protocol on MI ability in three male individuals with PKD, with an emphasis on examining changes in brain responses.Methods:Training was completed primarily at home, via audio recordings, and emphasized the imagination of functional tasks. MI ability was assessed pre and post-training using subjective and objective imagery questionnaires, alongside an electroencephalographic (EEG) recording of a functional MI task. EEG analysis focused on the mu rhythm, as it has been proposed that suppression in the mu rhythm may reflect MI success and motor learning. Previous research has indicated that mu suppression is impaired in individuals with PKD, and may contribute to the disease’s associated deficits in motor learning.Results:Following training, all three participants improved in MI accuracy, but reported no notable improvements in MI vividness. Greater suppression in the mu rhythm was also exhibited by all three participants post-training.Conclusion:These results suggest the participants learned from the training protocol and that individuals with PKD are responsive to MI training. Further research on a larger scale is needed to verify the findings and determine if this learning translates to improvements in motor function.

Mental Imagery in Patients with Prolonged Grief Disorder: a Comparison with Matched Bereaved Healthy Controls

Mental imagery is a transdiagnostic feature that has been increasingly researched in mental disorders in the past years. This study is the first to investigate mental imagery in individuals suffering from Prolonged Grief Disorder (PGD), a new disorder which will be included into the new edition of the International Classification of Diseases and Related Health Problems (ICD-11).Our objective was to find out to what extent patients suffering from PGD differ from healthy, but equally bereaved, controls in terms of mental imagery, and how mental imagery is related to psychopathology. Patients with PGD and matched bereaved healthy controls (n = 54) completed a mental imagery questionnaire specifically designed for the study, and other established measures of psychopathology. Patients suffering from PGD reported mental images more frequently, had less control over them, and described negative images as more vivid than did healthy controls. Also, in reaction to mental images, patients less frequently experienced joy, but more often grief, anger and guilt. Besides these group differences, significant correlations between mental imagery other psychopathological measures could be found. Mental imagery is clearly related to PGD. The underlying mechanisms on whether it is a developing or maintaining factor need to be addressed in future studies. Future research should also investigate in what way mental imagery might be used in therapeutic approaches.

Interference-based methods to mitigate gambling craving: a proof-of-principle pilot study

ABSTRACT Craving is central in the prognosis of gambling disorder. The elaborated intrusion theory (EIT) provides a sound framework to account for craving in addictive disorders, and interference methods inspired from the EIT have substantiated their effectiveness in mitigating substance and food-related cravings. The principle of these methods is to recruit the cognitive resources underlying craving (e.g., visuospatial skills, mental imagery) for another competitive and cognitively demanding task, thus reducing the vividness and overwhelming nature of craving. Here we conducted two experiments employing a between-subjects design to test the efficacy of interference methods for reducing laboratory-induced craving. In these experiments, gamblers (n = 38 for both experiments) first followed a craving induction procedure. They then performed either a visuospatial interference task (making a mental and vivid image of a bunch of keys [experiment 1] or playing the video game Tetris [experiment 2]; experimental conditions) or another task supposed not to recruit visuospatial skills and mental imagery (exploding bubble pack [experiment 1] or counting backwards [experiment 2]; control conditions). Results show that all methods successively mitigated induced craving. Although previous research evidenced the superiority of visuospatial tasks to reduce substance-related craving, our findings question their superiority in the context of gambling craving.

Characterizing robotic surgical expertise: An exploratory study of neural activation during mental imagery of robotic suturing

BackgroundMental imagery (MI) aids skill acquisition, however, it is unclear to what extend MI is used by experienced surgeons. The purpose of this study was to assess differences in MI of participants with varying surgical expertise in robotic surgery. MethodsStudents, residents, and surgeons completed the Mental Imagery Questionnaire to assess MI for robotic suturing. Participants then completed robotic simulator tasks, and imagined performing robotic suturing while being assessed with electroencephalogram (EEG). ResultsAttending surgeons reported higher MI for robotic suturing, and EEG revealed higher neural activation during imagery of robotic suturing than other groups. ConclusionsExperienced surgeons displayed higher MI ability for robotic suturing, and displayed higher cortical activity in the frontal and parietal areas of the brain, which is associated with more advanced motor imagery. MI appears to be a component of robotic surgery expertise.

Reduced visual acuity is mirrored in low vision imagery.

Research has examined the nature of visual imagery in normally sighted and blind subjects, but not in those with low vision. Findings with normally sighted subjects suggest that imagery involves primary visual areas of the brain. Since the plasticity of visual cortex appears to be limited in adulthood, we might expect imagery of those with adult-onset low vision to be relatively unaffected by these losses. But if visual imagery is based on recent and current experience, we would expect images of those with low vision to share some properties of impaired visual perception. We examined key parameters of mental images reported by normally sighted subjects, compared to those with early- and late-onset low vision, and with a group of subjects with restricted visual fields using an imagery questionnaire. We found evidence that those with reduced visual acuity report the imagery distances of objects to be closer than those with normal acuity and also depict objects in imagery with lower resolution than those with normal visual acuity. We also found that all low vision groups, like the normally sighted, image objects at a substantially greater distance than when asked to place them at a distance that 'just fits' their imagery field (overflow distance). All low vision groups, like the normally sighted, showed evidence of a limited visual field for imagery, but our group with restricted visual fields did not differ from the other groups in this respect. We conclude that imagery of those with low vision is similar to that of those with normal vision in being dependent on the size of objects or features being imaged, but that it also reflects their reduced visual acuity. We found no evidence for a dependence on imagery of age of onset or number of years of vision impairment.

An examination of imagery ability and imagery use in skilled golfers

Abstract Objectives The use of imagery to improve golf performance is well established and recognised as a key psychological technique in developing and maintaining excellence. However, the relationship between a golfer’s imagery ability and their imagery use is still poorly understood. The current study examined differences in participants vividness of movement imagery and imagery use and the extent their vividness of movement imagery predicted functions of imagery use. Methods One hundred and one male skilled golfers (Mage=27.80, SD=11.03) with CONGU recognised handicaps ranging from plus 4 to 5 (Mhandicap=1.32, SD=2.74) completed both the Vividness of Movement Imagery Questionnaire-2 (Roberts, R., Callow, N., Hardy, L., Markland, D., & Bringer, J. (2008). Movement imagery ability: Development and assessment of a revised version of the vividness of movement imagery questionnaire. Journal of Sport & Exercise Psychology, 30(2), 200–221) and Sports Imagery Questionnaire (Hall, C. R., Mack, D. E., Paivio, A., & Hauesenblas, H. A. (1998). Imagery use by athletes: Development of the sport imagery questionnaire. International Journal of Sport Psychology, 29, 73–89). Results The results demonstrated no significant differences between Internal and External visual imagery, however, Kinaesthetic imagery scores were significantly higher than External visual imagery scores. Significant differences in imagery use were recorded with participants reporting higher Cognitive specific imagery use scores compared to other functions of imagery use. Regression analyses indicted that golf handicap accounted for 12% in the variance of Cognitive specific imagery use with an additional 12% accounted for by Internal visual imagery and 7% Kinaesthetic imagery. For Cognitive general imagery use golf handicap accounted for 4% of the variance with Internal visual imagery adding a further 5% to the model. Conclusions Our findings highlight that vividness of movement imagery; specifically, Internal and Kinaesthetic imagery ability are significant predictors of skilled golfers Cognitive specific and Cognitive general imagery use.

Effect of positive and negative dimensions of mental imagery and self-talk on learning of soccer kicking skill

Background and Study Aim. Mental imagery and self-talk are two important mental skills that are used for improvement of performance and learning of motor and sport skills. This study aimed to investigate the effect of positive/negative mental imagery and positive/negative self-talk on learning of soccer kicking skill.
 Material and Methods. Participants included 48 young soccer player students. Participants were soccer player students with mean age 18.44 and SD=.88 years. After selecting the sample and filling out the personal detail form, the imagery and self-talk instructions, the method of completing mental imagery questionnaire, Moore-Christine kick-skill test instructions, and principles of free kick at soccer were explained to participants. Then, the mental imagery test and kick-skill test were run in 4 blocks of 4 attempts and the results were recorded. Based on their pre-test scores, the participants were divided into 4 groups. The acquisition sessions were held for 3 weeks and 2 sessions per week, with 8 blocks of 4 trials (32 trials) per session. The data was analyzed using one-way ANOVA, mixed ANOVA, and two-way ANOVA tests at different learning stages (significance level= 0.05).
 Results. The results of data analysis showed that positive imagery and positive self-talk groups performed significantly better than negative imagery and negative self-talk groups. Also, due to the significance of interactive effect of imagery × training sessions, it was found that the positive imagery groups performed significantly better than negative imagery groups from the third session onwards.
 Conclusion. According to the results, it was recommended that trainers use this aspect of self-talk at early stages of training. Also, the positive imagery can be emphasized by increasing the training sessions in more skilled individual.

POVEZANOST FENOMENA AFANTAZIJA SA PREFERENCIJOM KA ODREĐENIM FILMSKIM ŽANROVIMA

Aphantasia is a recently identified condition which is defined as the inability to create mental imagery. This study aimed to examine whether the level of mental imagery of respondents can be predicted based on the preference of the movie genre and to explore whether there are statistically significant differences between respondents who prefer different movie genres in terms of aphantasia. The sample consisted of 925 respondents (M= 187, F= 738). Age range in the sample was from 18 to 85 (M = 31.13; SD = 10.93). The aphantasia was operationalized through VVIQ (Vividness of Visual Imagery Questionnaire), the Instrument for Measuring Favorite Movie Genres, made for the purpose of this research was also used. Data processing was performed on the overall score of aphantasia, as well as on separate scales of open and closed eyes, and after that on a subsample of men and women, but the results were not statistically significant in any case. Both aphantasia scales of open (α = 0.874) and closed eyes (α = 0.936) show high internal consistency reliability. The results show that the phenomenon of aphantasia cannot be predicted based on the preferences of movie genres (F(6, 918) = 0.91, p = .489, R2 = .006), as well as that there are no statistically significant differences in aphantasia between respondents who prefer different film genres (F (5/919) = 0.16, p = .976). By the method of multiple linear regression of the opposite direction, we obtained that aphantasia can statistically significantly predict only the preferences of the Comedy genre (F(2, 922) = 4.67, p =.010; R2 = .010) with β = -.12; p = .003. Since different results are obtained in the reverse order, based on aphantasia we can predict preferences for movie genres to a certain extent, which could speak in favor of previously done researches that claimed aphantasia is congenital.

French Vividness of Olfactory Imagery Questionnaire: A Potential Tool for Diagnosing Olfactory Loss by Assessing Olfactory Imagery?

Several studies have shown a significant relationship between smelling and olfactory imagery abilities. The primary aim of the present study was to validate a French version of the Vividness of Olfactory Imagery Questionnaire (VOIQ). The secondary aim was to investigate its capability to differentiate individuals with smell loss from healthy individuals. After having elaborated a French translation of the VOIQ (fVOIQ), we evaluated olfactory imagery abilities of 387 French participants who anonymously self-completed the fVOIQ: 121 pathologic individuals (hyposmic and anosmic), 244 normosmic individuals (healthy non-expert), and 22 fragrance experts. Significant split-half reliability as expressed by Spearman correlation coefficients for the global sample, as well as for each group separately, indicated the excellent internal consistency of the fVOIQ. Moreover, results revealed a significant effect of the smelling ability group on fVOIQ score, suggesting that daily olfactory stimulation is fundamental to maintaining the ability to create a vivid image and that severe loss of smell may result in progressive impairment of olfactory imagery. Our fVOIQ and the original English version seemingly have similarly high benefit in differentiating experts and normosmic individuals based on their olfactory imagery ability. Moreover, the fVOIQ seems capable of differentiating individuals with loss of smell from healthy individuals. These findings demonstrate the reliability and validity of the fVOIQ, and its capability to differentiate individuals’ smelling ability according to their olfactory imagery ability.

The Examine of Imagination and Self-Efficacy Levels of Athletes in Terms of Some Variables

The aim of this study is to evaluate the imagery and self-efficacy beliefs of athletes. 35 male and 47 female; totally 82 athletes participated in the study. SIQ and SES scale was used to collect the data. SES (Self-Efficacy Scale) that was developed Riggs et al. (1994) was translated and adapted to Turkish by Öcel (2002). SIQ (Sport Imagery Questionnaire) especially developed for sports and it was designed by Hall et al (1998). Turkish adaptation of inventory was done by Kızıldağ in 2007.. According to t test results by gender comparative comparison, sub dimension of sport imagery questionnaire there is a statistically significant difference at the sub dimension of imagery which is the Motivational Specific Imagery and Motivational General Arousal Imagery (p<0.05). The Correlation results showed that there was a significant relationship between Cognitive Imagery and Self Efficacy; Motivational Specific Imagery and Self Efficacy; Motivational General-Mastery and Self Efficacy (p<0.05). The results of this study reveal that, the imagery change in terms of gender, imagery and self-efficacy beliefs show some relationships and this relationship is observable.

Children's motor imagery modality dominance modulates the role of attentional focus in motor skill learning.

We investigated whether children's motor imagery dominance modulated the relationship between attentional focus and motor learning of a tossing task. One hundred and thirty-eight boys (age: M=10.13, SD=0.65) completed the Movement Imagery Questionnaire - Children (MIQ-C) to determine imagery modality dominance (kinesthetic, internal-visual, external-visual) and were randomly assigned to either an internal (n=71) or external (n=67) attentional focus group. Participants completed 60 trials of a tossing task with their non-dominant hand on day 1. Participants in the internal focus group were asked "to focus on the throwing arm", whereas participants in the external focus group were instructed "to focus on the ball." A retention test was conducted 24h later to assess motor learning. Overall, the results from a nested, multiple linear regression analysis indicated the degree to which internal or external focus influences children's throwing accuracy is dependent upon their motor imagery modality dominance. Specifically, higher levels of external-visual imagery dominance resulted in greater motor learning for children adopting an external focus. In contrast, higher values of kinesthetic imagery dominance resulted in reduced motor learning for children who adopted an external focus. Despite the need for future research, we recommend motor imagery modality dominance assessments be considered when investigating the influence of attentional focus on motor learning, particularly when the target population is children.

Exploring the vividness of mental imagery and eidetic imagery in people with intellectual disability (ID) in comparison with typically developing (TD) individuals

BackgroundMental imagery (MI) has been described as the “ability to simulate in the mind information that is not currently being perceived by the sense organs” (Moran, 2012, p. 166). The vividness of mental imagery has been defined as the clarity, brightness, or intensity of an image as reported by the individual (Marks, 1973). There are many studies conducted on vividness in typically developing (TD) individuals, however, no attempt has been made either to assess the vividness of mental imagery in people with intellectual disability (ID) or compare it with that of typically developing (TD) adults. MetodsA vividness of imagery test (comprising a modified version of the Vividness of Visual Imagery Questionnaire 2, (VVIQ-2; Marks, 1995), and two items of the Age Projection Test, (APT; Ahsen, 1988) were administered to participants with mild, moderate, and severe ID. Their performance on the vividness scale was compared with typically developing individuals. Measures for cognitive and adaptive functioning were administered to ascertain the ID level of participants. ResultsThe results of this study reveal a non-significant group difference between people with mild ID, moderate ID, and TD on the vividness of mental imagery and eidetic imagery. People with severe ID performed significantly lower than the other three groups. ConclusionDespite their cognitive impairment, a non-significant difference between the performance of people with mild and moderate ID and typically developing individuals on imagery vividness scale is noteworthy.

GENDER DIFFERENCES IN VISUAL IMAGERY: OBJECT AND SPATIAL IMAGERY

Research findings on gender differences in visual imagery are mixed. One reason suggested to account for the inconsistent results has been the treatment of imagery as a unified construct despite the recent arguments of its multifaceted quality. In order to explore how visual imagery is related to gender, the present study differentiates between two different visual imagery construct; object and spatial imagery. In addition, it explores two other factors in characterizing gender differences: the type of the visual imagery measure (i.e., performance type vs. self-report measures) and academic training. One hundred and twenty undergraduates completed the Vividness of Visual Imagery (VVIQ), Mental Rotation Test (MRT) and Object-Spatial Imagery and Verbal Questionnaire (OSIVQ). Gender differences were observed in: (1) favoring females in the vividness measure as well as the object imagery questionnaire; (2) favoring males in the mental rotation performance and spatial imagery questionnaire. Academic training did not contribute as a factor. These results suggest that object and spatial imagery are differentially related to gender, and the type of the visual imagery measure does not seem to contribute to the story.

Neural Correlates of Motor Imagery of Gait in Amyotrophic Lateral Sclerosis.

Gait impairment is poorly characterized in amyotrophic lateral sclerosis (ALS), despite increasing evidence of extrapyramidal and cerebellar dysfunction. Gait impairment adds to the considerable motor disability of ALS patients and requires targeted multidisciplinary interventions. To assess gait imagery-specific networks and functional adaptation in ALS. Prospective. Seventeen ALS patients with lower motor neuron predominant (LMNp) disability, 14 patients with upper motor neurons predominant (UMNp) disease, and 14 healthy controls were included. 3T / gradient echo echo planar (GE-EPI). Subjects performed a dual motor imagery task: normal and precision gait. The Movement Imagery Questionnaire - Revised Second Version (MIQ-rs) was used to appraise movement imagery in each participant. Study group-specific activation patterns were evaluated during motor imagery of gait. Additional generalized psychophysiological interaction analyses were carried out using the supplementary motor area, caudate, cerebellum, and superior parietal lobule as seed regions. Repeated-measures analysis of variance (ANOVA) was used to compare time imagery and MIQ-rs scores between groups. Size effects were also reported as partial eta squared (η2). One-way ANOVA was performed to explore differences in terms of connexions during motor imagery tasks. A significant increase in imagery time in UMNp patients compared to controls (P < 0.05) and LMNp (P < 0.05) during imagined gait was demonstrated. UMNp patients exhibited altered supplementary motor area, precentral gyrus, superior parietal lobule, and dorsolateral prefrontal cortex activation and increased orbitofrontal (pFDR(False Discovery Rate) < 0.05), posterior parietal (pFDR < 0.05) caudate (pFDR < 0.05), and cerebellar (pFDR < 0.05) signal during imagined locomotion. Increased effective connectivity of the striato-cerebellar and parieto-cerebellar circuits was also demonstrated. Additional activation was detected in the insula and cingulate cortex. Enhanced striato- and parieto-cerebellar networks in UMNp ALS patients are likely to represent a compensatory response to impaired postural control. 2 TECHNICAL EFFICACY STAGE: 5.

Psychometric properties of the Spanish version of the Exercise Imagery Questionnaire (EIQ)

En este studio se evaluaron las propiedades psicométricas de la versión en español del Cuestionario de Imágenes de Ejercicio (EIQ) en un grupo de 166 ( 127 hombres y 39 mujeres ) estudiantes de de primer año de grado en Ciencias de la Actividad Física y del Deporte (Medad = 20.57, SD = 2,24). Los participantes realizaban ejercicio al menos 4 veces por semana. Además administramos la version Española de cuatro cuestionarios de imagen mental: MIQ-R, VMIQ, VVIQ, Gordon Test. Llevamos a cabo dos análisis confirmatorios del EIQ, en primer lugar, un modelo con tres factores (imagen de técnica, energía y apariencia) similar al original, aunque no cumplía los valores recomendados para un buen ajuste. Sin embargo, el ajuste del segundo modelo con dos factores (imagen de técnica y energía) fue bueno (CFI = .97, NNFI = .94, RMSEA = .07, SRMR = .04), con resultados similares a la prueba original. La fiabilidad medida a través del alfa de Cronbach fue acceptable pero la fiabilidad compuesta fue más baja de lo recommendable. La validez convergente y discriminate resultó adecuada. Encontramos una correlación significativa entre el EIQ técnica y el Gordon Test. También se incluyó una tabla de baremación del grupo estudiantes of Physical Activity and Sports Sciences. Los resultados se discutieron, y se observó que la version Española del EIQ es una prueba válida y útil para explorar, especialmente, dos tipos de imagen: técnica y energía. In this study, the psychometric properties of the Spanish version of the Exercise Imagery Questionnaire (EIQ) were evaluated in a sample of 166 first-year undergraduates of a Bachelor’s degree in Physical Activity and Sports Sciences, 127 men, and 39 woman; Mage = 20.57, SD = 2.24. Participants exercised at least 4 times a week. Moreover, the Spanish versions of four mental imagery questionnaires were administered: MIQ-R , VMIQ, VVIQ, and Gordon Test. Two confirmatory factor analyses of the EIQ were performed. First, a three-factor model (technique, energy, and appearance imagery) the same as the original model, failed to obtain the recommended values for a good fit. However, the second model adjusted to two factors (technique and energy imagery) was good (CFI = .97, NNFI = .94, RMSEA = .07, SRMR = .04) with results similar to the original test. Reliability was acceptable as measured by the Cronbach’s alpha, but composite reliability was lower than recommended. However, convergent and discriminant validity was inadequate. There was a significant correlation between the EIQ and the Gordon Test. Furthermore, Tables have been included as an aid the elucidation of the results of the sample of undergraduates on the Bachelor’s degree in Physical Activity and Sports Sciences. The results are discussed, and substantiated the Spanish version of the EIQ was a valid and useful test for exploring two types of imagery in particular: technique and energy. Neste estudo avaliamos as propriedades psicométricas da versão em espanhol do Exercise Image Questionnaire (EIQ). Participaram 166 (127 homens e 39 mulheres) alunos do primeiro ano de uma licenciatura em Atividade Física e Ciências do Desporto (Midade = 20.57, SD = 2,24). Os participantes exercitaram-se pelo menos 4 vezes por semana. Além disso, administramos a versão em espanhol de quatro questionários de imagem mental: MIQ-R, VMIQ, VVIQ, Gordon Test. Foram realizadas duas análises confirmatórias do EIQ, primeiro um modelo com três fatores (imagem técnica, energia e aparência), exatamente como o original, embora não se atendesse aos valores recomendados para um bom ajuste. No entanto, o ajuste do segundo modelo com dois fatores (técnica e imagem energética) foi bom (CFI = .97, NNFI = .94, RMSEA = .07, SRMR = .04) com resultados semelhantes ao teste original. A confiabilidade medida através do alfa de Cronbach foi aceitável, mas a confiabilidade composta foi menor que o recomendado. A validade convergente e discriminada foi adequada. Houve uma correlação significativa entre o EIQtécnica e o teste de Gordon. Também foi incluída uma tabela de escala do grupo de estudantes de Atividade Física e Ciências do Desporto. Os resultados foram discutidos, e observou-se que o EIQ é um teste válido e útil para explorar, principalmente, dois tipos de imagem: técnica e energia.

Futuristic VR image presentation technique for better mobile commerce effectiveness

Previous studies show that VR images can influence consumers’ attitudes and behaviors by evoking imagination. In this study, we introduce a reality-based closed-loop 3D image (hereafter Virtualgraph). Then, we try to see whether such image would increase evocativeness in a mobile commerce environment and whether higher telepresence of the visual image of a product can increase the purchase intention of that product. In order to find the above, we developed a model comprised of constructs containing telepresence, perceived value price, perceived food quality, and vividness of visual imagery questionnaire (VVIQ). We used Virtualgraph application to conduct an experiment and then conducted an interview as well as a survey. As results of the experiment, survey, and interview, we found the followings. First, users evoke imagination better with Virtualgraph than with still images. Second, increased evocativeness affects purchase intention if the perceived quality of fresh food product is satisfactory. Third, increased evocativeness makes users value products higher and do even much higher when the perceived quality of fresh food product is good. From the interview, we could find that the experimental group had higher purchase intentions and perceived products as more expensive ones. Also, they perceived images of products clearer and more vivid than did the control group. We also discuss the strategic implications of using Virtualgraph in mobile shopping malls.

Aprendizaje de palabras en euskera, altas y bajas en imagen, mediante la mnemotecnia de la palabra clave

La mnemotecnia de la palaba clave se utiliza para el aprendizaje de una lengua extranjera. Se ha comprobado su eficacia en muchas lenguas en todo el mundo. Este estudio tenía como objetivo analizar la eficacia de la mnemotecnia de la palabra clave en el aprendizaje del idioma euskera, utilizando listas largas de palabras, altas y bajas en imagen. Se ha utilizado un grupo de 424 estudiantes (226 mujeres y 198 hombres) de la Enseñanza Secundaria Obligatoria para que aprendiesen la traducción española de una lista de 28 palabras del euskera (14 altas en imagen y 14 bajas en imagen). Fueron administrados el Gordon Test of Visual Imagery Control y el Vividness of Visual Imagery Questionnaire. Se ha comprobado que la mnemotecnia de la palabra clave, cuando la palabra clave es elegida por los compañeros de los participantes, tuvo un mayor recuerdo de la traducción de palabras del euskera al español, que el grupo que utilizó el método de repetición y los grupos que utilizaron otros métodos de selección de la palabra clave. Se discuten los resultados y se proponen nuevas líneas de investigación.

Spanish Version of the Plymouth Sensory Imagery Questionnaire.

ObjectiveThe current interest in mental imagery in fields such as sport and physical training, health, education, underscore the need for designing general measures of imagery vividness that include different sensorial modalities such as the Plymouth Sensory Imagery Questionnaire (Psi-Q; Andrade et al., 2014). The Psi-Q measures imagery vividness in seven sensorial modalities with a factorial structure of seven factors corresponding to the sensorial modalities, and has good internal consistency. The aim of the present study was to translate the Psi-Q into Spanish and to assess its psychometric properties.MethodsThe questionnaire was back-translated, and administered to 394 fine arts undergraduates. Moreover, this test was compared to other questionnaires measuring different types de imagery.ResultsA confirmatory factor analysis found that the Psi-Q had seven factors (vision, sound, smell, taste, touch, bodily sensation, and emotional feeling) with results similar to the original test. Values suggested a better fit for the model of the short version. The internal consistency values were 0.93 for the long and 0.89 for the short test. The Psi-Q subscales correlated significantly (p < 0.01) with the total of the Betts’ QMI subscales, and the VVIQ, with the highest significance observed between the Psi-Q Touch and Betts’ QMI Cutaneous (r = −0.57), and between the Psi-Q Olfactory and Betts’ QMI Smell (r = −0.56). Owing to its novelty, the high correlation and significance (p < 0.01) between Psi-Q Vision and the OSIVQ Object (r = 0.36) is worth noting.ConclusionThe Spanish version of the Psi-Q was an adequate measure for evaluating different sensorial modalities of imagery vividness, and exhibited similar psychometric properties to those of the original version. The growing interest in mental imagery in different fields of application justifies the need for adapting the Psi-Q for the Spanish speaking population. This questionnaire is a valuable tool for the understanding of imagery as a psychological process, and as a variable influencing other processes.

INVESTIGATION OF IMAGERY STATUS OF AMATEUR SOCCER PLAYERS

The present study tries to explain what imagery is and how commonly it is used by athletes to increase performance. This study aims to provide information that imagery (mental visualization) is a very powerful tool to increase athletes’ performance and to provide guidance based on sport psychology. The aim of the present study is to determine the types and levels of using imagery in sport in amateur league Soccer players. Sport Imagery Questionnaire was given to a total of 190 Soccer players aged between 18 and 35 who were playing in amateur leagues of Samsun province. In the study conducted, no significant difference was found between the ages of female and male amateur Soccer players (p>0.05). At the same time, no significant difference was found between their sport years (p>0.05). In addition, no significant difference was found in motivational general mastery (MG- M) and (MS) in terms of gender and in the comparison of imagery scores in terms of age category and sport years (p<0.05). Conclusion: It is concluded that the visualization status of amateur Soccer players varies slightly according to gender, age group and year of sports. It was observed that the visualization scores were better as the age of sports increased. It is thought that starting sports at earlier contributes to the good visualization scores. It may be suggested that children should be directed to Soccer at an earlier age. Article visualizations:
