The effect of different combinations of physical activity and natural environment videos on children's attention levels between class breaks

BackgroundPhysical activity intervention and watching natural environment videos have been proven to improve young children’s attention levels. However, evidence comparing the improvement effects of different combinations of the two activities has rarely been reported. By comparing the differences in the improvement effects of four combinations of physical activities and watching natural environment videos on young children’s attention levels, this study can enrich the evidence in this research field and also provide a reference for arranging effective intervention methods for children’s attention recovery between classes.MethodA total of 152 children aged 4 to 6 years were recruited and randomly divided into four intervention groups: (1) physical activity intervention first and thereafter watching a natural environment video group (activity + video group), (2) watching a natural environment video first and thereafter the physical activity intervention group (video + activity group), (3) physical activity-based group, and (4) natural environment video-based group. Physical activity involved 4 min of moderate-intensity basic physical fitness combination training. The subjects wore the Pico Neo pioneer version of the VR glasses all-in-one machine to watch a natural environment video. Thereafter, population sociological variables and daily physical activity levels were investigated. Auditory and visual sustained attention tests were performed before and after intervention in each group.ResultThe auditory attention post-test scores of the four groups showed an improvement trend compared with the pretest scores. In particular, the activity + video group (F = 10.828; ɳp2 = 0.226; p = 0.002) and natural environment video-based group (F = 9.452; ɳp2 = 0.203; p = 0.004) have the best improvement effect. For visual attention, only the activity + video group showed a significant improvement trend (F = 4.287; ɳp2 = 0.104; p = 0.045), while the other three groups showed a downward trend in scores.ConclusionsAmong the different intervention combinations, the physical activity intervention first and watching natural environment videos thereafter group has the best effect on improving children’s attention during recess. Physical activity interventions at the end of recess adversely affect young children’s visual attention levels at the beginning of the class. Therefore, this study recommends that children should not engage in physical activity interventions in the second half of the class break. Lastly, the current research recommends presenting the content of physical activity interventions first and further improving their attention thereafter by watching natural environment videos.

Methylphenidate improves cognitive function and health-related quality of life in survivors of childhood brain tumours

ABSTRACT Objectives: The growing population of survivors of childhood brain tumors present the challenge of long-term quality of survival. The domains most affected by tumor and treatment are those implicated in development of typical intellectual functions: attention, working memory, and processing speed, with consequent effects upon function and quality of life. In this paper we present service evaluation data on the 12-month effect upon processing speed, visual and auditory attentional domains in 29 patients receiving methylphenidate aged 5-16 years (Mean=10.6). Methods: Patients received immediate-release methylphenidate and were converted to modified-release as appropriate. Mean optimal dose of immediate-release methylphenidate was 0.34 mg/kg per dose (range 0.2-0.67). Results: Patients showed a significant positive impact of methylphenidate on attention in all tests of selective visual attention from the Test of Everyday Attention for Children 2. A significant improvement was also shown on response time. Significant change was not found on psychometric measures of sustained auditory or visual attention, or selective auditory attention. Ratings of Health-Related Quality of Life showed a positive benefit of methylphenidate at 12 months. Side effects were minimal and not statistically significant. Conclusions: Survivors of childhood brain tumor with attentional and processing speed deficit show clinical benefit from methylphenidate.

Potential predictors of smoking relapse in treatment-seeking smokers

Impulsive behavior problems are powerful predictors of addiction treatment outcomes. However, a comprehensive assessment of these features has not been examined in relation to smoking cessation outcomes. This study aims to evaluate the capacity of impulsive behavior to predict the risk of relapse and the number of relapses for smokers. The sample comprised 141 participants (Mage= 47.3, SD= 8.31; 59% females) in psychopharmacology treatment for dependence to nicotine. Participants provided breath carbon monoxide samples for determining smoking throughout the study. The different impulsiveness dimensions were evaluated with a Go/NoGo task, the visual search and attention test and a delayed discount task, while self-informed impulsivity was assessed with Barratt’s Impulsiveness Scale. Unplanned impulsivity, attention failures and performance in the Go/NoGo task are postulated among the individual factors related to the number of relapses. Our results contribute to the understanding of relapse components and enable the inference of assiduity by quantifying relapse.

Effects of Sitting Callisthenic Balance and Resistance Exercise Programs on Cognitive Function in Older Participants.

Exercise training programs have the potential to improve cognitive function in older subjects. However, the majority of training programs are based on aerobic modality. In the current study, the influence of 3 months programs of sitting callisthenic balance (SCB) and resistance training (RT) on cognitive functioning and the mediating role that a change in the level of neurotrophic factors and strength in older, healthy participants plays were examined. Global cognitive function was examined using MoCA, short-term memory using Digit Span and Delayed Matching to Sample, set shifting using Trial Making Test Part B, speed of processing simple visual stimuli using Simple Reaction Time, decision making using Choice Reaction Time, visual attention with Visual Attention Test (VAT), tests. Strength of lower and upper limbs, neurotrophin level (irisin, brain-derived neurotrophic factor (BDNF), neurotrophin 3 (NT-3), neurotrophin 4/5 (NT 4/5) were examined. Improved scores in RT vs. SCB were noted in MoCA (p = 0.02), reaction time in SRT (p = 0.02), TMT B (p = 0.03), errors committed in CRT (p = 0.04) and VAT (p = 0.02) were observed. No significant changes in the level of neurotrophic factors were observed. Changes in upper limb strength were related to changes in the number of errors committed in the SRT (p = 0.03). Lower limb strength changes explained the dynamics of the number of correct answers (p = 0.002) and errors committed (p = 0.006) in VAT. Both SCB and RT influenced multiple cognitive domains. The RT program improved global cognitive functioning, while no improvement was noticed in the SCB group. Decision making, visual attention and global cognitive function were improved after the RT program. Set-shifting, short-term visual memory processing speed of simple visual stimuli were improved after the SCB program, while a decrease in the processing speed of simple visual stimuli was noted in the RT group. Changes in irisin were related to set-shifting and short-term memory, while in BDNF to an improvement in the processing speed of simple visual stimuli. Resistance exercise training programs could be applied to prevent age related declines of cognitive function in healthy older subjects.

Lower extremities task of pressing an "accelerator" or a "brake": association with traffic accidents in older drivers - a preliminary study.

It is important to add an on-road test, but if not possible, we can use simulators. Before doing simulators, it is important to use the right foot to control the accelerator and brake pedals. We applied the Posner paradigm (visual attention test) for lower extremities. The participants were older adults. They and their families had anxiety about their driving. The 66 participants (44 men and 22 women) were divided into groups with and without experience of a traffic accident, and the following tests were examined: General cognitive and executive function tests, the NPA test, and an original Lower Extremity Reaction Test. Each participant was asked to press the "brake" or "accelerator" pedal by the right foot as quickly as possible in response to a traffic situation shown on the screen. Compared to participants with favorable reactions to the Lower Extremity Reaction Test, those with poor reaction time tended to have more traffic accidents (OR=6.82), rather than the result of the NPA test. The results suggest that the probability of having a traffic accident can be better evaluated using the Lower Extremity Reaction Test.

L’utilisation précoce des écrans est-elle néfaste ? Une première réponse avec la cohorte Elfe

In France, a recent well-documented book by Desmurget (2019) severely condemned all use of screen by preschoolers. Desmurget speaks from a danger of decerebration leading to dumbass children. However, a critical analysis of his argumentation suggests that such a rejection could be an overly radical position. The French longitudinal study, Elfe, was initiated in 2011 on more than 18,000 newborns. Follow-up was intensive in the infancy and pre-school periods, including a telephone interview of the mother (or, if not available, the father) at age 3.5years. In this interview, the mothers answered many questions about the use of screens (here limited to tablets, computers, and smartphones) by their children. The children were then tested in 2016, when they were in the nursery school (4- to 5-year-olds, 57months in mean), with a large cognitive test, involving both literacy (n=35) and numeracy (n=24) items, and a visual attention test, the Teddy bears cancellation test. In the latter test, the participant is asked to cross out, with the pencil in his/her dominant hand, all the teddy bears (n=15) distributed on the page among 60 distractors in one minute of time. Moreover, the teachers were asked to rate the children's competence in cognitive (language, maths, sciences) and non-cognitive (physical or musical activities) domains and their social behaviors (helping, sharing, and attention to others) on a 3 or 5-items Likert-scale. Regression analysis of the total cognitive test score on the screen use, adjusted for age, gender, mother's study level, family's income, and number of siblings, showed an association between computer use and cognitive performance in nursery school. Correlations between screen use and, respectively, the cognitive test score, the visual attention test, the teachers’ rating about the performance or behavior of their students was never significantly negative. In fact, some were even significantly positive, albeit low and non-conclusive due to the limitations of the study. The results, both of the regression and correlational analyses, are consistent with our suggestion that Desmurget's position is overly radical but do not exclude that, in the long term, the early use of screen can be the basis of a future addiction.

The role of working memory in speech recognition by hearing-impaired older listeners: does the task matter?

Objective Working memory refers to a cognitive system that holds a limited amount of information in a temporarily heightened state of availability, for use in ongoing cognitive tasks. Research suggests a link between working memory and speech recognition. In this study, we investigated this relationship using two working memory tests that differed in regard to the operationalisation of the link between working memory and attention: the auditory visual divided attention test (AVDAT) and the widely used reading span test. Design The relationship between speech-in-noise recognition and working memory was examined for two different working memory tests that varied in methodological and theoretical aspects, using a within-subject design. Study sample Nineteen hearing-impaired older listeners participated. Results We found a strong link between the reading span test and speech-in-noise recognition and a less robust link between the AVDAT and speech-in-noise recognition. There was evidence for the role of selective attention in speech-in-noise recognition, shown via the new AVDAT measure. Conclusion Our findings suggest that the strength of the relationship between speech-in-noise recognition and working memory may be influenced by the match between the demands and the stimuli of the speech-in-noise task and those of the working memory test.

Attention deficits in Brazilian health care workers with chronic pain.

The impact of COVID-19 on chronic pain (CP) in non-infected vulnerable South American subjects is unknown. Healthcare workers (HCWs) are at increased risk for CP. During the pandemic, many HCWs with CP kept working. Knowing how cognition is affected by CP in these subjects is an important subject for work safety. The attention domain has a pivotal role in cognition. Previously, the Continuous Visual Attention Test (CVAT) was applied to detect specific attention deficits in fibromyalgia patients. The present investigation described CP prevalence in non-infected Brazilian HCWs during the pandemic and assessed HCWs' attentional performance with the aid of the CVAT. This study was carried out at a reference University Hospital in Rio de Janeiro, Brazil. HCWs of both sexes, aged 20 or older, were interviewed from August to December 2020. A 90-second version of the CVAT was performed. The average reaction time to correct responses and the respective intraindividual reaction time variability for correct responses to target (VRT) was determined. Omission and commission errors were also calculated. Then, for each participant we calculated the Z-scores of the CVAT variables based on the distribution of CVAT performance of 211 healthy subjects (reference-comparison group). HCWs with Z-scores > 1.64 were classified as significantly impaired. From the 154 selected HCWs, 72 reported CP during the pandemic (prevalence = 47%). Post hoc ANCOVAs showed that the average correct VRT was significantly higher in the CP group than in the non-CP group (F = 4.99, df = 1/150, p = 0.027, η2 = 0.032). The percentage of participants with impaired VRT performance was 30% (n = 21) in the CP group and 16% (n = 13) in the non-CP group. The difference between these two propositions reached significance (χ2 = 3.96, df = 1, p = 0.047). As VRT is associated with the sustained-attention subdomain, our data suggest that this subdomain is disrupted in the CP group.

Association of resting-state theta-gamma coupling with selective visual attention in children with tic disorders.

A tic disorder (TD) is a neurodevelopmental disorder characterized by tics, which are repetitive movements and/or vocalizations that occur due to aberrant sensory gating. Its pathophysiology involves dysfunction in multiple parts of the cortico-striato-thalamo-cortical circuits. Spontaneous brain activity during the resting state can be used to evaluate the baseline brain state, and it is associated with various aspects of behavior and cognitive processes. Theta–gamma coupling (TGC) is an emerging technique for examining how neural networks process information through interactions. However, the resting-state TGC of patients with TD and its correlation with cognitive function have not yet been studied. We investigated the resting-state TGC of 13 patients with TD and compared it with that of 13 age-matched healthy children. The participants underwent resting-state electroencephalography with their eyes closed. At the global level, patients with TD showed a significantly lower resting-state TGC than healthy children. Resting-state TGC with the eyes closed was significantly negatively correlated with the attention quotient calculated for omission errors in a selective visual attention test. These findings indicate that the resting-state brain network, which is important for the attentional processing of visual information, is dysfunctional in patients with TD. Additionally, these findings support the view that TGC reflects information processing and signal interactions at the global level. Patients with TD may have difficulty gating irrelevant sensory information in the resting state while their eyes are closed.

The effect of opioid-sparing anesthesia regimen on short-term cognitive function after thoracoscopic surgery: a prospective cohort study

BackgroundAs type of surgery and opioids are suggested risk factors for the development of cognitive decline after surgery, we evaluated the effect of an opioid-sparing anesthesia regimen involving preoperative erector spinae block and continuous infusion of flurbiprofen on the incidence of cognitive decline after video-assisted thoracoscopic surgery.MethodsIn this observational study, patients over 18 years old presenting for elective video-assisted thoracoscopic surgery were divided into two groups, the erector spinae plane block group (ESPB group, who received preoperative single shot of bi-level ESPB at T4 and T6 levels) and the control group who received intercostal nerve blocks through T5 to T7 intercostal spaces along mid-axillary line after surgery. Continuous infusion of flurbiprofen (8 mg/h) and intravenous oxycodone rescue (1 mg/bolus, lockout time 10 minutes) were provided as postoperative analgesics. Cognitive function was measured one day before and 48 h after surgery with brief Cogstate computerized battery (CCB).ResultsThere were 60 patients included with 30 in each group. Perioperative sufentanil dose was significantly reduced in ESPB group. Nine (30%) and 15 (50%) patients had delayed neurocognitive recovery in the ESPB group and the control group respectively. Psychomotor speed and visual attention tests were the two tests that patients showed cognitive decline. The results of multivariate regression revealed that patients who were more than 53.5 years of age (OR 9.213, 95% CI 1.789, 47.437, P = 0.008) and low levels of education (less than 9 years of complimentary education) (OR 6.829, 95% CI 1.068, 43.677, P = 0.042) were independent risk factors for postoperative delayed neurocognitive recovery. For subgroup analysis, ESPB could reduce the occurrence of delayed neurocognitive recovery in patients with both risk factors (6/10 (60%) vs. 11/11 (100%), P = 0.004) compared to the control group.ConclusionsMiddle-aged people and low levels of education are independent risk factors for delayed neurocognitive recovery after thoracoscopic surgery. ESPB has the potential to prevent cognitive decline in high-risk patients.Trial registrationChiCTR1800014508 (www.chictr.org.cn, January 17, 2018; Hong Zhao, M.D.). URL: http://www.chictr.org.cn/showproj.aspx?proj=24778. The date of the enrolment of the first participant to the trial was January 22, 2018.

Horses' attentional characteristics differ according to the type of work.

Attention is a central process of cognition and influences the execution of daily tasks. In humans, different types of work require different attentional skills and sport performance is associated with the ability to attention shift. Attention towards humans varies in dogs used for different types of work. Whether this variation is due to the recruitment of individuals suitable for specific types of work, or to the characteristics of the work, remains unclear. In the present study, we hypothesized that domestic horses (Equus caballus) trained for different types of work would also demonstrate different attentional characteristics but we also explored other possible factors of influence such as age, sex and breed. We exposed more than sixty horses, working in 4 different disciplines, and living in two types of housing conditions, to a visual attention test (VAT) performed in the home environment. Individual attentional characteristics in the test were not significantly influenced by age, sex, breed or conditions of life but were strongly related to the type of work. Riding school horses showed longer sequences and less fragmented attention than all other horses, including sport horses living in the same conditions. Interestingly, sport performance was correlated with attention fragmentation during the test in eventing horses, which may need more attention shifting during the competitions. Working conditions may influence attention characteristics indirectly through welfare, or directly through selection and training. Our study opens new lines of thought on the determinants of animal cognition and its plasticity and constitutes a further step towards understanding the interrelationship between working conditions and cognition.

Computerized working memory training in males with Duchenne muscular dystrophy: A single case experimental design study

ABSTRACT Learning disabilities (LDs) and working memory problems (WM) are common brain-related comorbidities in Duchenne muscular dystrophy (DMD). Despite growing evidence on the efficacy of computerized WM training in children with LDs, research in DMD is lacking. This exploratory study assessed whether training (1) improves dystrophin-associated WM problems in DMD, (2) effects are present at post-intervention, 3 and 8 months follow-up, and (3) improves problems that arise from their LDs. A single case non-concurrent multiple baseline across patients design evaluated the target behaviour i.e. parental reports of WM problems of four DMD participants with LDs. Additionally, participants completed cognitive tests of verbal and visual WM, academics, attention, processing speed and fluid reasoning. Parents and teachers completed behavioural questionnaires. Testing and questionnaires were administered at baseline, post-intervention (T2), 3 (T3) and 8 (T4) months follow-up. Positive effects on target behaviour were found for three of four participants, but parental bias cannot be ruled out. Short and long-term, near-and far transfer effects were found for verbal and visual WM (T2:n = 2, T3&T4:n = 1), reading (T2:n = 4,T3:n = 3,T4:n = 2), arithmetic (all T:n = 1), processing speed (all T:n = 4) and fluid reasoning (T2:n = 1,T3&T4:n = 2). Behavioural questionnaires displayed minimal changes (T2:n = 1,T3&T4:n = 2). Promising WM training results are shown in DMD that merit further research.

Visual spatial attention and its impact on the accuracy of the diagonal spike in volleyball

The primary aim of this research was to study visual spatial attention and its impact on the accuracy of the diagonal spike in volleyball. A total of 20 volleyball players of Baghdad participated in this study. The sample was homogeneous in terms of height, weight and age of the players. The tests used in the present study were: 1) Visual Spatial Attention Test. 2) Volleyball Spike Test. Based on the findings of the study, the researcher concluded that visual spatial attention has a significant impact on the accuracy of the diagonal spike in volleyball.

Evidence for superior encoding of detailed visual memories in deaf signers

Recent evidence shows that deaf signers outperform hearing non-signers in some tests of visual attention and discrimination. Furthermore, they can retain visual information better over short periods, i.e., seconds. However, it is unknown if deaf signers’ retention of detailed visual information is superior following more extended periods. We report a study investigating this possibility. Our data revealed that deaf individuals outperformed hearing people in a visual long-term memory test that probed the fine detail of new memories. Deaf individuals also performed better in a scene-discrimination test, which correlated positively with performance on the long-term memory test. Our findings provide evidence that deaf signers can demonstrate superior visual long-term memory, possibly because of enhanced visual attention during encoding. The relative contributions of factors including sign language fluency, protracted practice, and neural plasticity are still to be established. Our findings add to evidence showing that deaf signers are at an advantage in some respects, including the retention of detailed visual memories over the longer term.

The statistical processing confirmed the validity of the specialized intervention carried out.

Attention profile of physically recovered COVID-19 inpatients on the day of discharge

Few studies have reported specific attention deficits in post-COVID-19 patients. Attention consists of different subdomains. Disruptions to specific attention subdomains might impair a wide range of everyday tasks, including road safety. As there are millions of COVID-19 patients with different socio-economic backgrounds, screening of attentional performance less dependent on education is needed. Here, we verified if physically recovered COVID-19 inpatients showed specific attention decrements at discharge. The Continuous Visual Attention Test (CVAT) is a Go/No-go task which is independent of participants’ schooling. It detects visuomotor reaction time (RT = intrinsic alertness), variability of reaction time (VRT = sustained attention), omission (focused-attention), and commission errors (response-inhibition). Thirty physically functional COVID-19 inpatients at discharge and 30 non-infected controls underwent the CVAT. A MANCOVA was performed to examine differences between controls and patients, followed by post-hoc ANCOVAs. Then, we identified the percentile score for each patient within the distribution of the CVAT performance of 211 subjects mentally capable of driving (reference group). COVID-19 patients at discharge showed greater RT and VRT, and more omission errors than controls. Twenty-two patients (73%) had performance below the 5th percentile of the reference group in one or more subdomains. As slow visuomotor RT, deficits in focusing and difficulties in keeping visual attention are associated with traffic accidents, we concluded that most COVID-19 patients at discharge had deficits that may increase the risk of road injuries. As these deficits will probably affect other daily activities, a routine assessment with the CVAT could provide useful information on whom to send to post-COVID centers.

Sex differences in the cognitive performance in adults: role of impaired sleep.

ObjectivesPoor sleep quality negatively affects cognitive performance. However, there are limited data on sex differences in functional outcomes of impaired sleep on cognition. Therefore, the aim of this study was to evaluate the association between sleep quality and performance of men and women in cognitive tests.Material and MethodsAfter screening, 97 individuals with and without insomnia complaints participated of this study. Behavioral scales were evaluated using a number of instruments and the sleep pattern was recorded by actigraph. Subsequently, the participants were submitted to visuospatial/verbal working memory (WM), visual attention, and psychomotor vigilance tests (PVT).ResultsThe actigraphic recordings indicated that men sleep later (d=-0.56, p<0.05), fall asleep faster (d=0.42, p<0.05), showed shorter sleep duration (d=0.53, p<0.05), and more sleep fragmentation than women (d=-0.41, p<0.05). The performance in the cognitive tasks also showed sex differences: the men showed better performance in the visuospatial short-term memory (d=-0.78, p<0.05); verbal (d=-0.61, p<0.05), and visuospatial-WM tests (d=-0.84, p<0.05); they also responded faster in the PVT (d=0.69, p<0.05), although made more mistakes (d=-0.85, p<0.01). Longer sleep latency was associated with poor performance in visual attention (r=0.52, p<0.05) and verbal memory tasks (r=-0.30, p<0.05) in men.ConclusionOur results suggest that difficulty in falling asleep was associated with cognitive impairment, especially in men. Sex differences in sleep quality and cognitive skills should be taken into account in future research in this field.

Effects of an Eye-Tracking Linkage Attention Training System on Cognitive Function Compared to Conventional Computerized Cognitive Training System in Patients with Stroke.

Objective: The purpose of the study was to investigate the effects of an eye-tracking linkage attention training system on cognitive function compared to a conventional computerized cognitive training system in stroke patients with cognitive impairment. Methods: This retrospective study was enrolled 40 stroke patients who received cognitive rehabilitation. The intervention consisted of 30 sessions and 30 min per session. Before and after the intervention, we assessed cognitive functions by Mini-Mental State Examination (MMSE-K) and activities of daily living by Modified Barthel Index (K-MBI) and administered a computerized neuropsychological test (CNT). Results: In both groups, there were significant improvements in MMSE-K and K-MBI (p < 0.05). In the visual and auditory attention test of the CNT, the eye-tracking linkage attention training group was significantly improved after intervention (p < 0.05). However, there were no significant differences in the conventional computerized cognitive training group. In addition, there were significant improvements in all memory tests of the CNT in the eye-tracking linkage attention training group. However, in the conventional computerized cognitive training group, there were significant improvements in some memory tests of the CNT. Conclusions: The training of poststroke cognitive impairment patients using an eye-tracking linkage attention training system may improve visuospatial attention and may be helpful for the improvement of short-term memory and independent performances in daily life activities.

Long-term neurocognitive, psychological, and return to work outcomes in meningioma patients.

This study aimed to investigate long-term neurocognitive, psychological, and return to work (RTW) outcomes in meningioma patients, and to explore whether neurocognitive and psychological factors influence RTW outcomes in this population. In this retrospective study, 61 meningioma patients completed in-depth clinical neuropsychological assessments. Of these participants, 42 were of working-age and had RTW information available following neuropsychological assessment. Seventy-one percent and 80% of patients received radiation and surgery, respectively, with 49% receiving both radiation and surgery. Associations between demographic, medical, neurocognitive, psychological, and RTW data were analyzed using multivariable logistic regression analyses. In our sample, 68% of patients exhibited global neurocognitive impairment, with the largest effect sizes found on tests of visual memory (d = 0.73), executive function (d = 0.61), and attention (d = 0.54). Twenty-seven percent exhibited moderate to severe levels of depressive symptoms. In addition, 23% and 30% exhibited clinically significant state and trait anxiety, respectively. Forty-eight percent of patients were unable to RTW. Younger age, faster visuomotor processing speed, and, unexpectedly, higher trait anxiety scores were associated with an increased likelihood of returning to work. Meningioma patients are at risk of experiencing neurocognitive deficits, psychological symptoms, and difficulties returning to work. Our results suggest that neurocognitive and psychological factors contribute to RTW status in meningioma patients. Prospective research studies are necessary to increase our understanding of the complexity of functional disability in this growing population.

Development of a neuropsychological assessment in smoking.

Smoking is one of the causes leading to the development of disease and mortality worldwide. One of the focuses of interest in this area is the impact of smoking on neuropsychological health. However, few studies provide instruments to assess executive functioning in smokers. The purpose of this study was to examine the viability of the internal structure of a neuropsychological battery for the assessment of executive function in smokers. A total of 171 smokers (Mage= 47.44, SDage= 8.48) were assessed. Executive functions were assessed at baseline with measures of inhibition (go/no go task and five digit test), updating (visual search and attention test and letter-number sequencing) and shifting (delay discounting task and Iowa gambling task). The exploratory factor analysis obtained a three-component solution of 59.6%. Establishing a first factor composed of visual search and attention test and letter-number sequencing, a second factor composed of delay discounting task and go/no go task and a third factor with Iowa gambling task and five digit test. The analysis of the internal structure reflected three factors which are consistent with the structure proposed by Miyake (2000).
