Significant Contextual Effects Research Articles

Age-related contextual cueing features are more evident in reaction variability than in reaction time.

Visual-spatial contextual cueing learning underpins the daily lives of older adults, enabling them to navigate their surroundings, perform daily activities, and maintain cognitive function. While the contextual cueing effect has received increasing attention from researchers, the relationship between this cognitive ability and healthy ageing remains controversial. To investigate whether visual-spatial contextual cueing learning declines with age, we examined the contextual learning patterns of older (60-71 years old) and younger adults (18-26 years old) using a contextual-guided visual search paradigm and response variability measurements. We observed significant contextual learning effects in both age groups, impacting response speed and variability, with these effects persisting for at least 24 days. However, older adults required more repetitions and memorised fewer repeated stimuli during initial learning. Interestingly, their long-term memory maintenance appeared stronger, as their contextual facilitation persisted in both response speed and variability, while younger adults only persisted in response speed but not variability. Overall, our results suggest an age-related complex and diverse contextual cueing pattern, with older adults showing weaker learning but stronger long-term memory maintenance compared with younger adults.

Context and Mutation in Gymnosperm Chloroplast DNA.

Mutations and subsequent repair processes are known to be strongly context-dependent in the flowering-plant chloroplast genome. At least six flanking bases, three on each side, can have an influence on the relative rates of different types of mutation at any given site. In this analysis, examine context and substitution at noncoding and fourfold degenerate coding sites in gymnosperm DNA. The sequences are analyzed in sets of three, allowing the inference of the substitution direction and the generation of context-dependent rate matrices. The size of the dataset limits the analysis to the tetranucleotide context of the sites, but the evidence shows that there are significant contextual effects, with patterns that are similar to those observed in angiosperms. These effects most likely represent an influence on the underlying mutation/repair dynamics. The data extend the plastome lineages that feature very complex patterns of mutation, which can have significant effects on the evolutionary dynamics of the chloroplast genome.

Bilingual phonological contrast perception: The influence of Quanzhou Southern Min on Mandarin non-sibilant fricative discrimination.

This study explores the discrimination of Mandarin non-sibilant fricatives by bilingual speakers (N = 40) of Quanzhou Southern Min (L1) and Mandarin (L2) in different phonological contexts, including rounded vowels and the glide [w]. The results of the ABX discrimination task indicate significant contextual effects of the following sound, in line with predictions based on the Perceptual Assimilation model (PAM) [Best (1995). J. Phon. 20(3), 305-330]. Additionally, the observed result could not be fully explained by the acoustic distance between stimuli, and discrimination ability was better for speakers with more exposure to and use of Mandarin.

Delivering context for fragrance evaluation: A study using trained sensory panellists

Extensive research has been carried out to investigate the effect of context (such as the external environment) on product perception, with previous studies focusing on food or beverage products using naïve consumers. However, it is still unclear whether context affects assessments made by trained panellists when testing fragranced stimuli. Options for conducting sensory testing outside of traditional sensory booths would allow for greater ecological validity and enable sensory testing to become more agile and flexible, with this need becoming even more important as a result of the Covid-19 pandemic. The current research set out to establish whether context has an effect on the perception of fragranced products using a trained sensory panel by testing 5 laundry market products under different context environments (No Context, Imagine, Visual Cue, Priming, Immersive). Statistically significant contextual effects were only observed for two out of the eleven attributes tested (Overall intensity and Herbal). Additional analyses using PCA showed that the same products were grouped together, whereas groupings by context were not observed. These findings suggest that perception of fragranced laundry products is not significantly impacted by different contexts when assessed by trained panellists. One possible explanation is that panellist training removes any influence of the external environment on product perception. Future studies could explore whether other contextual parameters have a greater influence on fragrance perception for trained panellists.

Contextual cueing in co-active visual search: Joint action allows acquisition of task-irrelevant context.

Repeatedly presenting a target within a stable search array facilitates visual search, an effect termed contextual cueing. Previous solo-performance studies have shown that successful acquisition of contextual memories requires explicit allocation of attentional resources to the task-relevant repeated contexts. By contrast, repeated but task-irrelevant contexts could not be learned when presented together with repeated task-relevant contexts due to a blocking effect. Here we investigated if such blocking of context learning could be diminished in a social context, when the task-irrelevant context is task-relevant for a co-actor in a joint action search mode. We adopted the contextual cueing paradigm and extended this to the co-active search mode. Participants learned a context-cued subset of the search displays (color-defined) in the training phase, and their search performance was tested in the transfer phase, where previously irrelevant and relevant subsets were swapped. The experiments were conducted either in a solo search mode (Experiments 1 and 3) or in a co-active search mode (Experiment 2). Consistent with the classical contextual cueing studies, contextual cueing was observed in the training phase of all three experiments. Importantly, however, in the "swapped" test session, a significant contextual cueing effect was manifested only in the co-active search mode, not in the solo search mode. Our findings suggest that social context may widen the scope of attention, thus facilitating the acquisition of task-irrelevant contexts.

"Blue Sky Effect": Contextual Influences on Pupil Size During Naturalistic Visual Search.

Pupil size is influenced by cognitive and non-cognitive factors. One of the strongest modulators of pupil size is scene luminance, which complicates studies of cognitive pupillometry in environments with complex patterns of visual stimulation. To help understand how dynamic visual scene statistics influence pupil size during an active visual search task in a visually rich 3D virtual environment (VE), we analyzed the correlation between pupil size and intensity changes of image pixels in the red, green, and blue (RGB) channels within a large window (~14 degrees) surrounding the gaze position over time. Overall, blue and green channels had a stronger influence on pupil size than the red channel. The correlation maps were not consistent with the hypothesis of a foveal bias for luminance, instead revealing a significant contextual effect, whereby pixels above the gaze point in the green/blue channels had a disproportionate impact on pupil size. We hypothesized this differential sensitivity of pupil responsiveness to blue light from above as a “blue sky effect,” and confirmed this finding with a follow-on experiment with a controlled laboratory task. Pupillary constrictions were significantly stronger when blue was presented above fixation (paired with luminance-matched gray on bottom) compared to below fixation. This effect was specific for the blue color channel and this stimulus orientation. These results highlight the differential sensitivity of pupillary responses to scene statistics in studies or applications that involve complex visual environments and suggest blue light as a predominant factor influencing pupil size.

National pride, social trust, and cultural nativism: Findings from East and Southeast Asia

Using the latest (fourth) wave of Asian Barometer Survey (2014–2016), this study examines how national pride and two types of trust (general and particular) are related to nativist preference (cultural nativism), independent of anti-immigration attitudes, among citizens in East and Southeast Asian countries. Findings from multilevel models show that, at the individual level, national pride and particular trust are positively related to cultural nativism, while general trust is negatively related. At the subnational-regional level, we also find significant contextual effects. Living in geographic areas with greater national pride is positively associated with nativist preference, as is residency in places with higher levels of particular trust. In contrast, residency in subnational contexts with higher levels of general trust is negatively associated. Finally, the association between national pride and cultural nativism is stronger in regions with greater contextual national pride.

Impact of the consciousness factor on the green travel behavior of urban residents: An analysis based on interaction and regulating effects in Chinese cultural context

Green travel contributes to energy saving and emission reduction. Understanding the factors affecting residents’ green travel behavior is vital to its implementation. This study aims to identify factors that can encourage residents to implement green travel behavior from the perspective of the consciousness-behavior gap. We divided green travel behavior into self-practice green travel behavior (SPGTB) and interpersonal promotion green travel behavior (IPGTB) and examined the consciousness-context-behavior theoretical framework by using a survey (N = 1475), which was sent to urban residents in the east region of China. The findings were as follows. (1) Urban residents adopt more SPGTB than IPGTB, but their green travel behavior implementation levels are lower than their green travel consciousness levels. (2) Both the consciousness and behavior factors have obvious differences on the individual characteristic factors, but their variation trends are the exact opposite. (3) Green travel consciousness had an immediate main effect on green travel behavior, but it varied in the two types of green travel behavior, and there were interaction effects among the part consciousness factors. (4) Internal and external situational factors had significant regulating effects on part consciousness-behavior paths. (5) The Chinese cultural context (“face” culture) displayed significant contextual effects on the relationships between the consciousness factors, situational factors and green travel behaviors. The first three results indicate the existence of consciousness-behavior gap, and the last two explain why the gap exists. Finally, some relevant suggestions are put forward to promote urban residents’ green travel behavior and a high level of consistency in the consciousness and behavior.

Correlates of Parental Choice of Child Discipline Methods in Ghana: A Multilevel Modeling Approach

This study applied multilevel modeling to investigate the impact of observed predictors and different levels or groups that households belong, on parents’ choice of discipline methods using data from 8156 households derived from a nationwide survey by the Ghana Statistical Service (GSS) in 2011. The aim of the study is to provide in-depth information on why parents choose particular discipline methods as corrective measures to reduce unwanted child behaviour in the present and to increase desirable ones in the future. The results of the study show that, religion and age-group of household heads have significant effect on household’s likelihood to choose physical discipline methods whereas the wealth index of a household and ethnicity of the household head, have significant effect on households’ likelihood to choose non-physical and psychological aggression methods. The results further show significant contextual effect on the differences in choices of parents at the household and regional levels. The choice of physical discipline methods by parents was consistent across households and regional levels unlike non-physical and psychological aggression methods whose application varied across the regions. Households in the Northern, Eastern and Volta regions mostly chose to apply physical discipline methods whereas in the Upper West, Western and Northern regions the most chosen discipline methods were non-physical discipline methods. Psychological aggression discipline methods were predominantly applied in the Upper East, Central and Northern regions of the country.

Exploring the Association between Suicidality and Smoking Behavior among School-Based Children in Lao People’s Democratic Republic (PDR)

ABSTRACTThis study examines the relationship between suicidality and smoking behavior. Specifically, it examines how and the degree to which suicide ideation and plan are associated with the probability of being a regular smoker among school-based children. Data come from Lao Student Health Survey (2017), a project funded by the National Research Foundation of Korea. Using primary hierarchically nested data (students clustered in classrooms across schools), we investigate the complex interplay between suicidality and smoking behavior in Lao PDR, a low-income country located in Southeast Asia. Results from fitting two-level random intercept models show that net of controls (e.g., gender, age, parental regulation, self-rated health, household SES), the likelihood of daily smoking is higher among students who have seriously considered committing suicide or have planned a suicide attempt. Controlling for individual-level factors, significant classroom-level contextual effects are also found with respect to peer relations. Finally, we observe a cross-level interaction: the positive association between suicide intent and odds of smoking is weaker in classrooms with better peer relations.

Status perception, residential context and subjective wellbeing among South Korean adults: A multilevel analysis of primary survey data

This study examines the multilevel associations between perceived socioeconomic status (SES) and subjective wellbeing (SWB) among community residing South Korean adults. Based on primary survey data, this research provides evidence on the contingent ways in which status perception and wellbeing are associated across individual and contextual (residential-community) levels. Three related but distinct questions guide the analysis. First, net of objective SES indicators (income, education, employment status, homeownership and financial assets), is perceived status related to SWB? Second, is the community-level status, net of individual-level status, associated with wellbeing? Lastly, how do residential characteristics moderate the linkage between status perception and SWB? Results from fitting hierarchical linear models reveal that perceived status is significantly and positively related to SWB. Adjusting for individual-level controls, significant contextual effect also emerges, i.e., residence in a higher-status community is associated with greater wellbeing. Finally, the relationship between status perception and SWB is stronger in lower-quality communities measured in terms of aggregate perceived SES, level of business commercialization (e.g., density of factories), suicide prevalence, and proportion of government welfare recipients.

School variation in offending: A macro-level strain approach

This study employs Macro-level Strain Theory (MST) as a framework to provide a better understanding of the way in which the structural and social context of Stockholm schools covaries with self-reported violent and general offending. The findings contribute to the literature in this area by directing a special focus at the interplay between the theory’s macro-level components and some individual-level mechanisms that may be assumed to condition the effect of strain on offending. Using multi-level data on 4789 students nested in 82 schools (violent offending) and 4643 students nested in 83 schools (general offending) in the City of Stockholm, the study notes significant contextual effects of anger, meaninglessness and life dissatisfaction on offending. School-level deprivation appears to have a confounding effect on the relationship between school-contextual negative affect and offending. Further, school-contextual anger influences some individuals more than others. Implications of these findings are discussed.

Global Repetition Influences Contextual Cueing.

Our visual system has a striking ability to improve visual search based on the learning of repeated ambient regularities, an effect named contextual cueing. Whereas most of the previous studies investigated contextual cueing effect with the same number of repeated and non-repeated search displays per block, the current study focused on whether a global repetition frequency formed by different presentation ratios between the repeated and non-repeated configurations influence contextual cueing effect. Specifically, the number of repeated and non-repeated displays presented in each block was manipulated: 12:12, 20:4, 4:20, and 4:4 in Experiments 1–4, respectively. The results revealed a significant contextual cueing effect when the global repetition frequency is high (≥1:1 ratio) in Experiments 1, 2, and 4, given that processing of repeated displays was expedited relative to non-repeated displays. Nevertheless, the contextual cueing effect reduced to a non-significant level when the repetition frequency reduced to 4:20 in Experiment 3. These results suggested that the presentation frequency of repeated relative to the non-repeated displays could influence the strength of contextual cueing. In other words, global repetition statistics could be a crucial factor to mediate contextual cueing effect.

Cultural concealment and therapy outcomes.

Therapy is predicated on the need for clients to share intimate details about their lives, including their cultural values, attitudes, and beliefs. Previous studies have found that clients conceal certain aspects of their lives including, but not limited to their symptoms and their feelings about the therapy process. To date, there has not been an investigation focused on whether clients conceal aspects of their cultural identities, whether some therapists are more likely to have clients conceal aspects of their cultural identities, and if cultural concealment is associated with therapy outcomes. The present study attempted to do so utilizing the caseloads of 37 therapists who treated a total of 233 clients in a university counseling center setting. Client data were collected at the end of treatment utilizing the Patient's Estimate of Improvement (PEI; Hatcher & Barends, 1996), a measure that assesses client change on domains including general functioning, symptom related distress, intimate and social relationships, work or school, feelings about oneself, behavior, control of life, and tolerance for and ability to share painful feelings. Cultural concealment was assessed via 5 items regarding the amount and circumstances under which clients withheld cultural identity based information in therapy. Results indicated that within therapists' caseloads, client's ratings of cultural concealment were negatively associated with therapy outcomes. Additionally, therapists whose clients rated more cultural concealment on average had clients with worse therapy outcomes. Lastly, there was a significant contextual effect indicating that within and between therapist cultural concealment were statistically different from one another. (PsycINFO Database Record

Putting "context" in context: The effects of body posture and emotion scene on adult categorizations of disgust facial expressions.

Affective face perception is influenced by nonfacial contextual elements. However, investigations often conflate body posture and emotion scene, making it unclear whether posture or the combination of posture and scene produces perception-altering effects. This study examined adults' categorizations of disgust facial expressions superimposed onto isolated emotion postures or postures embedded in emotion scenes. Results indicated that emotional postures exerted a significant contextual effect on adults' emotion categorizations of disgust faces. Of note, postures in emotion scenes exerted a stronger contextual effect than isolated postures for sadness and fear contexts. These findings suggest that contextual elements exert varying degrees of influence on emotion perception and produce combinatorial effects. (PsycINFO Database Record

“Dior, J’adore”: The role of contextual information of luxury on emotional responses to perfumes

Luxury conveys values of quality and rarity and holds a particular emotional meaning. Yet, studies conducted on the impact of contextual information of luxury on emotional responses to products remain scarce. In this study, we tested whether contextual information, in particular evoking luxury, could influence emotional responses to perfumes, which are known to be powerful elicitors of emotion. More specifically, we measured the subjective, physiological, and expressive components of participants’ emotional responses. We conducted an experiment in which participants had to smell and assess perfumed pens as well as blank pens (i.e., without perfume) presented either in a luxurious context (i.e., name, brand and bottle), a non-luxurious one, or no information. Results indicated that participants tended to rate perfumes as more pleasant and rated them as more familiar when presented in a luxurious context than in a non-luxurious one or without context, and the blank pen as more irritating in a non-luxurious context than in a luxurious one. However, we did not find evidence of a significant contextual information effect on expressive or physiological indicators. Our findings suggest that contextual information of luxury can moderately influence the subjective component of participants’ emotional responses, while no evidence for such effect was found with respect to the physiological and expressive components.

The Contextual Effects of Political Trust on Happiness: Evidence from China

Political trust is often considered as legitimacy enhancing, but whether political trust is well-being enhancing is still underexplored. Using micro data from the East Asian Social Survey 2012, this study investigates the association between province-level/aggregate political trust and individual happiness in China, and explores the role of economic development in influencing individual political trust after the period of rapid growth in 1990–2010. Results show a positive and significant contextual effect of political trust on individual happiness in China, with the endogeneity problem addressed by an instrument variables method. Currently in China, it is a higher provincial rate of GDP growth rather than GDP per capita that predicts a higher level of political trust. Economic growth still significantly reinforces the level of individual political trust and even helps to raise individual political trust among economically disadvantaged populations. The “critical citizens” phenomenon has not yet grown into a nationwide trend. Since the positive contextual effect of political trust on individual subjective well-being, policy makers are encouraged to maintain the stock of political trust through good governance.

NEIGHBORHOOD SOCIAL CONTROL AND PERCEPTIONS OF CRIME AND DISORDER IN CONTEMPORARY URBAN CHINA*

By drawing on the two streams of Western literature on “neighborhood effects” and perceptions of neighborhood disorder adapted to the distinctive organizational infrastructure of neighborhoods in contemporary urban China, we examine the contextual effects of different forms of neighborhood social control (i.e., collective efficacy, semipublic control, public control, and market‐based control) on different types of perceived disorder (i.e., criminal activity, social disorder, physical disorder, and total disorder) across neighborhoods. The analyses are based on data collected in the year 2013 from a survey of approximately 2,500 households in 50 neighborhoods across the city of Tianjin. Collective efficacy as a form of informal control has a significant effect only for perceived social disorder. Public control as measured by the activities of neighborhood police stations has a significant contextual effect on all forms of perceived disorder, whereas the role of market‐based control as represented by contracted community services is limited to perceived physical disorder. Finally, semipublic control as measured by the activities of neighborhood committees significantly affects all forms of perceived disorder, but the direction of the effect is positive. We interpret this positive effect with reference to the complex processes surrounding the “translation” of neighborhood disorderly conditions into perceptions of disorder.

A Multilevel Examination of the Relationship Between Racial Tension and Attitudes Toward the Police

Prior research has established the effect of race and ethnicity on citizens’ perceptions of the police. This paper serves to build on this body of literature by examining the effect of racial tension on attitudes toward the police. Specifically, we conduct multilevel analyses using survey data from Seattle, Washington to explore whether individual perceptions of racial tension and/or community-level racial tension are related to residents’ attitudes toward the police. The results show that attitudes toward the police were generally less favorable among respondents who perceived racial tension or mistrust in their communities. Additionally, community racial tension had significant contextual effects on residents’ perceived racial profiling by the police. This study has implications for future police policy: understanding how racial tension shapes perceptions of the police will assist in selecting and adapting crime control strategies.

The impact of signal-to-noise ratio on contextual cueing in children and adults

Contextual cueing refers to a form of implicit spatial learning where participants incidentally learn to associate a target location with its repeated spatial context. Successful contextual learning produces an efficient visual search through familiar environments. Despite the fact that children exhibit the basic ability of implicit spatial learning, their general effectiveness in this form of learning can be compromised by other development-dependent factors. Learning to extract useful information (signal) in the presence of various amounts of irrelevant or distracting information (noise) characterizes one of the most important changes that occur with cognitive development. This research investigated whether signal-to-noise ratio (S/N) affects contextual cueing differently in children and adults. S/N was operationally defined as the ratio of repeated versus new displays encountered over time. Three ratio conditions were created: high (100%), medium (67%), and low (33%) conditions. Results suggested no difference in the acquisition of contextual learning effects in the high and medium conditions across three age groups (6- to 8-year-olds, 10- to 12-year-olds, and young adults). However, a significant developmental difference emerged in the low S/N condition. As predicted, adults exhibited significant contextual cueing effects, whereas older children showed marginally significant contextual cueing and younger children did not show cueing effects. Group differences in the ability to exhibit implicit contextual learning under low S/N conditions and the implications of this difference are discussed.
