Abnormalities in early visual processes are linked to hypersociability and atypical evaluation of facial trustworthiness: An ERP study with Williams syndrome

Accurate assessment of trustworthiness is fundamental to successful and adaptive social behavior. Initially, people assess trustworthiness from facial appearance alone. These assessments then inform critical approach or avoid decisions. Individuals with Williams syndrome (WS) exhibit a heightened social drive, especially toward strangers. This study investigated the temporal dynamics of facial trustworthiness evaluation in neurotypic adults (TD) and individuals with WS. We examined whether differences in neural activity during trustworthiness evaluation may explain increased approach motivation in WS compared to TD individuals. Event-related potentials were recorded while participants appraised faces previously rated as trustworthy or untrustworthy. TD participants showed increased sensitivity to untrustworthy faces within the first 65–90 ms, indexed by the negative-going rise of the P1 onset (oP1). The amplitude of the oP1 difference to untrustworthy minus trustworthy faces was correlated with lower approachability scores. In contrast, participants with WS showed increased N170 amplitudes to trustworthy faces. The N170 difference to low–high-trust faces was correlated with low approachability in TD and high approachability in WS. The findings suggest that hypersociability associated with WS may arise from abnormalities in the timing and organization of early visual brain activity during trustworthiness evaluation. More generally, the study provides support for the hypothesis that impairments in low-level perceptual processes can have a cascading effect on social cognition.     

Mediating Role of Memory of Another Person's Choicein Social Influence on Preference

We often tend to fit our subjective preference with those of others after merely being faced with what other people prefer. This is known as social conformity. However, it is still unclear how the impact of such a social influence on subjective preference is modulated by the personal characteristics of the other person (e.g., whether the person is trustworthy) and the explicit memory of those personal characteristics (e.g., remembering who evaluated the objects). To clarify explicit memory's underlying role regarding social influence, we asked participants to evaluate their preference for abstract paintings both before and after observing binary choices made by others whose behaviors could be labeled as trustworthy, neutral, or untrustworthy. The results showed the following: (a) even without explicit memory of who made a choice and which painting was chosen, the participants preferred chosen over unchosen paintings; and (b) such preference changes were modulated by the subjective trustworthiness of others only when they explicitly remembered who made a choice.     

The dissociable influence of social context on judgements of facial attractiveness and trustworthiness

The cheerleader effect occurs when the same face is rated to be more attractive when it is seen in a group compared to when seen alone. We investigated whether this phenomenon also occurs for trustworthiness judgements, and examined how these effects are influenced by the characteristics of the individual being evaluated and those of the group they are seen in. Across three experiments, we reliably replicated the cheerleader effect. Most faces became more attractive in a group. Yet, the size of the cheerleader effect that each face experienced was not related to its own attractiveness, nor to the attractiveness of the group or the group’s digitally averaged face. We discuss the implications of our findings for the hierarchical encoding and contrast mechanisms that have previously been used to explain the cheerleader effect. Surprisingly, judgements of facial trustworthiness did not experience a ‘cheerleader effect’. Instead, we found that untrustworthy faces became significantly more trustworthy in all groups, while there was no change for faces that were already trustworthy alone. Taken together, our results demonstrate that social context can have a dissociable influence on our first impressions, depending on the trait being evaluated.     

认知需求和认知闭合需求对风险决策中外语效应的影响

外语效应指相比于母语背景,个体在外语背景下风险决策偏差会降低。针对影响外语效应的因素研究大多聚焦于外部因素和与个体外语水平相关的因素,少有研究探讨认知风格的作用。本研究通过524名成人被试,探索认知需求和认知闭合需求对外语效应的影响。结果表明:(1)风险决策中存在外语效应,相比于母语背景,外语背景下框架效应被削弱,且个体更偏向风险寻求。(2)对于认知需求和认知闭合需求都高或都低的个体,语言类型会影响风险决策,在母语环境下倾向于风险规避,在外语环境下倾向于风险寻求;而对于认知需求和认知闭合需求高低不一致的个体,语言类型对其风险决策倾向的影响不显著。本研究为认知风格如何综合影响风险决策提供了进一步的证据。     

Need for Cognition and the process of lie detection

Four experiments investigated the influence of Need for Cognition on the process of lie detection. According to the basic assumptions of dual process models, only higher Need for Cognition leads to the use of verbal information when making judgments of veracity. People with lower Need for Cognition predominantly use stereotypical nonverbal information for their judgments. In both Experiments 1 and 2, participants saw a film in which nonverbal cues (fidgety vs. calm movements) and verbal cues (low vs. high plausibility) were manipulated. As predicted, when Need for Cognition was lower, only the nonverbal cues influenced participants' judgments of veracity. In contrast, participants with higher Need for Cognition also used the verbal cues. Experiments 3 and 4 tested the hypothesis that higher Need for Cognition leads to better discrimination of truthful from deceptive messages. Both experiments found that participants with higher Need for Cognition achieved higher accuracy at classifying truthful and deceptive messages than participants with lower Need for Cognition.     

Novice Strategies for Understanding Paintings

Visual analysis is taught in art history classes as a skill which aids a student in understanding a work of art in its appropriate conceptual or historical context. To provide a foundation for the design of computer-based lessons to train students in the skill, this study attempted to discover the strategies that novices employ when viewing a set of paintings. Verbal protocols obtained from novices in this study indicated that they described semantic features, or content, of paintings more than the formal elements, e. g. line, colour, shape, when viewing realist paintings. However, when presented with abstract, i. e. less semantically accessible paintings, novices shaply altered their approach and discussed formal elements over content. These findings suggest that an analysis of formal elements is not performed by a novice when a painting depicts a clear subject, but is attempted when the subject-matter becomes obscure. This implies that, at some level, novices realize that the meaning of a painting can be extracted from attention to the formal elements. Interestingly, novice protocols contained the same categories of strategies deemed important by experts. The lack of training in visual analysis was not notably manifest with respect to style. Of all formal dimensions, this one yielded the greatest discrepancy between novices and the expectations of instructors.

Attentional inhibition has social-emotional consequences for unfamiliar faces

Visual attention studies often rely on response time measures to show the impact of attentional facilitation and inhibition. Here we extend the investigation of the effects of attention on behavior and show that prior attentional states associated with unfamiliar faces can influence subsequent social-emotional judgments about those faces. Participants were shown pairs of face images and were asked to withhold a response if a transparent stop-signal cue appeared over one of the faces. This served to associate the cued face with an inhibitory state. Later, when asked to make social-emotional choices about these face pairs, participants chose uncued faces more often than cued faces as "more trustworthy" and chose cued faces more often than uncued faces as "less trustworthy." For perceptual choices, there was no effect of how the question was framed (which face is "on a lighter background" vs. "on a darker background"). These results suggest that attentional inhibition can be associated with socially relevant stimuli, such as faces, and can have specific, deleterious effects on social-emotional judgments.     

Learning about faces: effects of trustworthiness on affective evaluation

The results of two studies on the relationship between evaluations of trustworthiness, valence and arousal of faces are reported. In Experiment 1, valence and trustworthiness judgments of faces were positively correlated, while arousal was negatively correlated with both trustworthiness and valence. In Experiment 2, learning about faces based on their emotional expression and the extent to which this learning is influenced by perceived trustworthiness was investigated. Neutral faces of different models differing in trustworthiness were repeatedly associated with happy or with angry expressions and the participants were asked to categorize each neutral face as belonging to a "friend" or to an "enemy" based on these associations. Four pairing conditions were defined in terms of the congruency between trustworthiness level and expression: Trustworthy-congruent, trustworthy-incongruent, untrustworthy-congruent and untrustworthy-incongruent. Categorization accuracy during the learning phase and face evaluation after learning were measured. During learning, participants learned to categorize with similar efficiency trustworthy and untrustworthy faces as friends or enemies and thus no effects of congruency were found. In the evaluation phase, faces of enemies were rated as more negative and arousing than those of friends, thus showing that learning was effective to change the affective value of the faces. However, faces of untrustworthy models were still judged on average more negative and arousing than those of trustworthy ones. In conclusion, although face trustworthiness did not influence learning of associations between faces and positive or negative social information it did have a significant influence on face evaluation that was manifest even after that learning.     

Need for Cognition and Cognitive Performance From a Cross-Cultural Perspective: Examples of Academic Success and Solving Anagrams

The cross-cultural validity of the Need for Cognition Scale and its relationship with cognitive performance were investigated in two studies. In the first study, the relationships between the scale and university entrance scores, course grades, study skills, and social desirability were examined. Using the short form of the Turkish version of the Need for Cognition Scale (S. Gülgöz & C. J. Sadowski, 1995) no correlation with academic performance was found but there was significant correlation with a study skills scale and a social desirability scale created for this study. When regression analysis was used to predict grade point average, the Need for Cognition Scale was a significant predictor. In the second study, participants low or high in need for cognition solved multiple-solution anagrams. The instructions preceding the task set the participants' expectations regarding task difficulty. An interaction between expectation and need for cognition indicated that participants with low need for cognition performed worse when they expected difficult problems. Results of the two studies showed that need for cognition has cross-cultural validity and that its effect on cognitive performance was mediated by other variables.

Personality and judgements of abstract,pop art,and representational paintings

This study was concerned with the question of which personality variables are most predictive of judgements of particular types of painting. One hundred and twenty‐one participants rated 24 slides of abstract, pop art, and representational paintings. They then completed two questionnaires which measured sensation seeking (SS) and the ‘Big Five’ personality dimensions. Thrill and Adventure Seeking was positively correlated with a liking of representational art while Disinhibition was associated with positive ratings of abstract art and pop art. Neuroticism was positively correlated with positive ratings of abstract and pop art, while conscientiousness was linked to liking of representational art. Openness to Experience was linked to positive ratings of all three art types. Agreeableness was negatively linked to liking of pop art. It was also found that art education and frequency of visits to art galleries were linked to positive ratings of abstract paintings. Regressional analyses showed about a fifth of the variance could be accounted for by personality and demographic variables. Personality variables were most strongly linked to positive judgements of representational art and least related to ratings of pop art. Overall the sensation seeking variables accounted for more of the variance than the big five dimensions. Copyright © 2001 John Wiley & Sons, Ltd.     

Eye'm lovin' it! The role of gazing awareness in mimetic desires

Recent studies showed that people evaluate objects more favorably when these objects are gazed-at by others, an effect coined as “mimetic desire”. In two studies, we tested whether mimetic desire stems from an automatic form of learning by examining one dimension of automaticity, i.e., people's awareness of the object-gaze association. Participants saw 6 neutral art paintings associated with a female gazing toward two of the paintings, away from two of the paintings, and closing her eyes with respect to the last two paintings. After the exposition phase, participants evaluated the paintings and performed a contingency-awareness test. Importantly, participants' responses on this test were genuinely driven by memory and not by inferences from liking. Results show that participants preferred objects that were gazed-at but only when they were aware of the object-gaze association. Hence, despite the adaptive function of joint attention, its impact on valence acquisition does not seem to qualify as an implicit learning process.     

What Kind of Paintings Inspire Children when Viewing Art?

Viewing art inspires creativity, which can encourage learning in art education. A previous study revealed that the type of artwork and the way art is viewed affects adults' inspiration; however, no study exists concerning the way children are inspired by viewing art. Thus, the current study aimed to examine whether children's age group/grade level, art style (figurative or abstract), and artwork creators (children or adults) influence children's inspiration, and whether the effects of the art style and creators vary by children's age group/grade level. An online questionnaire survey was conducted with the help of 600 pairs of parents and their elementary-school-aged children. They were asked to view eight paintings that differed in terms of the artists and their individual style and they then rated their inspiration experience when viewing each artwork. The results revealed that children were more inspired when viewing abstract, rather than figurative, paintings, and the effect of the type of painting differed in the third and sixth grades. Additionally, children gained more inspiration by viewing paintings created by children rather than by adults; a difference observed in all grade levels.

Appreciating art verbally: Verbalization can make a work of art be both undeservedly loved and unjustly maligned

Two experiments examined whether appreciating art verbally would aesthetically confuse viewers. Participants were asked to verbalize why they either liked or disliked two different kinds of paintings; one piece was representational, the other piece was abstract. Those who verbalized their reasons for liking the artworks were more likely to prefer the representational painting, whereas those who verbalized their reasons for disliking the paintings were also more likely to dislike the representational painting. While it was easy to describe reasons for both liking and disliking representational art, the same proved difficult for abstract art. The findings suggest that due to its figurative qualities people will be encouraged to generate reasons to describe representational art, rather than abstract art, and that these reasons could potentially be biased and cause them to change their preferences in line with these reasons.     

Age-related similarities and differences in first impressions of trustworthiness

Trust is a particularly under-studied aspect of social relationships in older age. In the current study, young (n = 35) and older adults (n = 35) completed a series of one-shot social economic trust games in which they invested real money with trustees. There were potential gains with each investment and also a risk of losing everything if the trustee was untrustworthy. The reputation and facial appearance of each trustee were manipulated to make them appear more or less trustworthy. Results revealed that young and older adults invest more money with trustees whose facial appearance and reputation indicate that they are trustworthy rather than untrustworthy. However, older adults were more likely than young to invest with trustees who had a reputation for being untrustworthy. We discuss whether age-related differences in responding to negative information may account for an age-related increase in trust, particularly when trusting someone with a reputation for being uncooperative.     

Variations in intensity statistics for representational and abstract art, and for art from the Eastern and Western hemispheres

Two recent studies suggest that natural scenes and paintings show similar statistical properties. But does the content or region of origin of an artwork affect its statistical properties? We addressed this question by having judges place paintings from a large, diverse collection of paintings into one of three subject-matter categories using a forced-choice paradigm. Basic statistics for images whose caterogization was agreed by all judges showed no significant differences between those judged to be 'landscape' and 'portrait/still-life', but these two classes differed from paintings judged to be 'abstract'. All categories showed basic spatial statistical regularities similar to those typical of natural scenes. A test of the full painting collection (140 images) with respect to the works' place of origin (provenance) showed significant differences between Eastern works and Western ones, differences which we find are likely related to the materials and the choice of background color. Although artists deviate slightly from reproducing natural statistics in abstract art (compared to representational art), the great majority of human art likely shares basic statistical limitations. We argue that statistical regularities in art are rooted in the need to make art visible to the eye, not in the inherent aesthetic value of natural-scene statistics, and we suggest that variability in spatial statistics may be generally imposed by manufacture.
