Gaze cueing of attention: Visual attention, social cognition, and individual differences.

During social interactions, people's eyes convey a wealth of information about their direction of attention and their emotional and mental states. This review aims to provide a comprehensive overview of past and current research into the perception of gaze behavior and its effect on the observer. This encompasses the perception of gaze direction and its influence on perception of the other person, as well as gaze-following behavior such as joint attention, in infant, adult, and clinical populations. Particular focus is given to the gaze-cueing paradigm that has been used to investigate the mechanisms of joint attention. The contribution of this paradigm has been significant and will likely continue to advance knowledge across diverse fields within psychology and neuroscience.

Age-related declines in basic social perception: Evidence from tasks assessing eye-gaze processing.

Previous research has investigated age differences in complex social perception tasks such as theory of mind and emotion recognition, with predominant findings of age-related declines. The present study investigated whether there are also age-related changes in basic aspects of social perception. Individuals' ability both to detect subtle differences in eye-gaze direction (e.g., where someone is looking in the environment) and to subsequently use these gaze cues to engage in joint attention with others was assessed. Age-related declines were found in the detection of the most subtle differences in gaze aversion. The ability to engage in joint attention by following gaze cues also declined with age. These age differences were not solely attributable to age impairments in visual perception and visual attention. The potential role of age-related neural declines in social perception problems was considered, along with the implications that age deficits in these basic social skills may have for older adults' social perception.

Children reason about shared preferences.

Two-year-old children’s reasoning about the relation between their own and others’ preferences was investigated across two studies. In Experiment 1, children first observed 2 actors display their individual preferences for various toys. Children were then asked to make inferences about new, visually inaccessible toys and books that were described as being the favorite of each actor, unfamiliar to each actor, or disliked by each actor. Children tended to select the favorite toys and books from the actor who shared their own preference but chose randomly when the new items were unfamiliar to or disliked by the two actors. Experiment 2 extended these findings, showing that children do not generalize a shared preference across unrelated categories of items. Taken together, the results suggest that young children readily recognize when another person holds a preference similar to their own and use that knowledge appropriately to achieve desired outcomes.

Infants' understanding of the link between visual perception and emotion: "If she can't see me doing it, she won't get angry."

Two experiments investigated 18-month-olds' understanding of the link between visual perception and emotion. Infants watched an adult perform actions on objects. An emoter then expressed neutral affect or anger toward the adult in response to the adult's actions. Subsequently, infants were given 20 s to interact with each object. In Experiment 1, the emoter faced infants with a neutral expression during each 20-s response period but looked at either a magazine or the infant. In Experiment 2, the emoter faced infants with a neutral expression, and her eyes were either open or closed. When the emoter visually monitored infants' actions, the infants regulated their object-directed behavior on the basis of their memory of the emoter's affect. However, if the previously angry emoter read a magazine (Experiment 1) or closed her eyes (Experiment 2), infants were not governed by her prior emotion. Infants behaved as if they expected the emoter to get angry only if she could see them performing the actions. These findings suggest that infants appreciate how people's visual experiences influence their emotions and use this information to regulate their own behavior.

Theory of Mind and Motion Perception in Schizophrenia.

This study investigated the relationship between theory of mind (ToM) deficits and visual perception in patients with schizophrenia (N=52; 17 remitted and unmedicated) compared with healthy controls (N=30). ToM was assessed with the Eyes Test, which asked participants to choose which of 4 words best described the mental state of a person whose eyes were depicted in a photograph. Visual perception was evaluated with form and motion coherence threshold measurements. Results revealed that patients with schizophrenia (both remitted and nonremitted) showed deficits on the Eyes Test and the motion coherence task. ToM dysfunctions were associated with higher motion coherence thresholds and more severe negative symptoms. This suggests that ToM deficits are related to motion perception dysfunctions, which indicates a possible role of motion-sensitive areas in the pathophysiology of schizophrenia.

Seeing it their way: Evidence for rapid and involuntary computation of what other people see.

In a series of three visual perspective-taking experiments, we asked adult participants to judge their own or someone else's visual perspective in situations where both perspectives were either the same or different. We found that participants could not easily ignore what someone else saw when making self-perspective judgments. This was observed even when participants were only required to take their own perspective within the same block of trials (Experiment 2) or even within the entire experiment (Experiment 3), i.e. under conditions which gave participants a clear opportunity to adopt a strategy of ignoring the other person's irrelevant perspective. Under some circumstances, participants were also more efficient at judging the other person's perspective than at judging their own perspective. Collectively, these results suggest that adults make use of rapid and efficient processes to compute what other people can see. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Some problems with social cognition models: A pragmatic and conceptual analysis.

Empirical articles published between 1997 and 2001 from 4 health psychology journals that tested or applied 1 or more social cognition models (theory of reasoned action, theory of planned behavior, health belief model, and protection motivation theory; N=47) were scrutinized for their pragmatic and conceptual basis. In terms of their pragmatic basis, these 4 models were useful for guiding research. The analysis of their conceptual basis was less positive. First, these models do not enable the generation of hypotheses because their constructs are unspecific; they therefore cannot be tested. Second, they focus on analytic truths rather than synthetic ones, and the conclusions resulting from their application are often true by definition rather than by observation. Finally, they may create and change both cognitions and behavior rather than describe them. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual differences in social loafing: Need for cognition as a motivator in collective performance.

Numerous situational factors have been found to moderate the extent to which individuals engage in social loafing, but few studies have investigated the influence of individual differences on individual motivation within groups. The present study examined whether need for cognition, an individual's tendency to engage in and enjoy effortful cognitive endeavors, moderates social loafing effects. It was predicted that individuals with a high need for cognition would be less likely to loaf on a cognitively engaging task. Individuals with a low need for cognition performed significantly better in the coactive than in the collective condition, whereas individuals with a high need for cognition worked just as hard collectively as coactively. Results were interpreted within the collective effort model (S. J. Karau & K. D. Williams, 1993). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual differences in perceiving and recognizing faces—One element of social cognition.

Recognizing faces swiftly and accurately is of paramount importance to humans as a social species. Individual differences in the ability to perform these tasks may therefore reflect important aspects of social or emotional intelligence. Although functional models of face cognition based on group and single case studies postulate multiple component processes, little is known about the ability structure underlying individual differences in face cognition. In 2 large individual differences experiments (N = 151 and N = 209), a broad variety of face-cognition tasks were tested and the component abilities of face cognition—face perception, face memory, and the speed of face cognition—were identified and then replicated. Experiment 2 also showed that the 3 face-cognition abilities are clearly distinct from immediate and delayed memory, mental speed, general cognitive ability, and object cognition. These results converge with functional and neuroanatomical models of face cognition by demonstrating the difference between face perception and face memory. The results also underline the importance of distinguishing between speed and accuracy of face cognition. Together our results provide a first step toward establishing face-processing abilities as an independent ability reflecting elements of social intelligence.

Dualism redux in recent neuroscience: "Theory of mind" and "embodied simulation" hypotheses in light of historical debates about perception, cognition, and mind.

How do we, as humans, take in the feelings and thoughts of other people? Theory-of-Mind (ToM) and Embodied Simulation (ES) approaches hypothesize divergent neural and behavioral mechanisms underlying intersubjectivity. ToM investigators assert that humans take in the belief states and intentions of another person by holding "a theory of mind" that cognitively posits the other person's mental contents, with some experiments identifying the right temporo-parietal junction as a specific ToM brain region. ES theorists hypothesize that humans perceive the other's state of mind by simulating his/her actions, emotions, and goals in the "mirror neuron system" in the brain. A historical review suggests these understandings rely on opposing, dualist models of cognition and perception. William James's intervention on this earlier debate is informative in anticipating recent findings in low-level sensory neuroscience. Of specific interest are studies showing that intersubjectivity and low-level sensory attentional filtering are both processed in the same cortical area (the temporo-parietal junction) suggesting that the ability to entertain other minds may be related to the ability to perceive salient stimuli during attention-demanding tasks.

Tell-tale eyes: Children's attribution of gaze aversion as a lying cue.

This study examined whether the well-documented adult tendency to perceive gaze aversion as a lying cue is also evident in children. In Experiment 1, 6-year-olds, 9-year-olds, and adults were shown video vignettes of speakers who either maintained or avoided eye contact while answering an interviewer's questions. Participants evaluated whether the speaker was telling the truth or lying on each trial. The results revealed that at both ages, children were more likely to attribute lying to speakers in the gaze aversion condition; however, the effect was significantly greater among 9-year-olds. Significant gender differences were also uncovered, with girls demonstrating strongest sensitivity to the gaze cue. Experiment 2 replicated the gender effect in 6-year-olds but found that when the speakers' verbal responses were removed, boys' use of the gaze cue increased and the gender difference disappeared. These findings indicate that at 6 years old, children interpret interpersonal gaze behavior as a socially informative cue. Furthermore, the growing appreciation of the stereotypic gaze behavior associated with lying and the reputed female advantage in gaze sensitivity may reflect differential processing of multimodal communication.

Evidence for social anxiety and impaired social cognition in a mouse model of fragile X syndrome.

This study assessed social behavior in a mouse model of Fragile X syndrome (FXS), the Fmr1 tm1Cgr or Fmr1 "knockout" (KO) mouse. Both the KO and wild-type (WT) mice preferred to be near a novel conspecific than to be alone. However, during the initial interaction with a novel conspecific, (1) a greater proportion of the KO mice exhibited high levels of grooming; and (2) the average duration of nose contact with the stimulus mouse was significantly shorter for the KO mice, both indicative of increased arousal and/or anxiety. Both groups exhibited a robust novelty preference when the novel animal was a "preferred" mouse. However, when the novel mouse was a "nonpreferred" animal, both groups showed a diminished novelty preference but this effect was more pronounced for the WT mice. This blunted negative reaction of the KO mice to a nonpreferred animal may indicate that they were less proficient than controls in distinguishing between positive and negative social interactions. These findings provide support for the use of this animal model to study the autistic features of FXS and autism spectrum disorders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Methamphetamine abuse and impairment of social functioning: A review of the underlying neurophysiological causes and behavioral implications.

The highly addictive drug methamphetamine has been associated with impairments in social cognitions as evidenced by changes in users' behaviors. Physiological changes in brain structure and functioning, particularly in the frontal lobe, have also been identified. The authors propose a biopsychosocial approach to understanding the effects of methamphetamine addiction by relating the physiological effects of the drug to the behaviors and social cognitions of its users, through the application of the theory of mind paradigm. Although onset of methamphetamine use has been linked to the desire for socialization, chronic use has been associated with an increase in depression, aggressiveness, and social isolation, behaviors that also implicate involvement of the frontal lobe. The reviewed literature provides strong circumstantial evidence that social-cognitive functioning is significantly impacted by methamphetamine use and that the social isolation, depression, and aggressiveness associated with chronic use is due to more than just the social withdrawal associated with addiction. Treatment considerations for methamphetamine must therefore consider the role of social cognition, and pharmacological responses must address the documented impact of the drug on frontal lobe functioning.

Evidence for deficits on different components of theory of mind in Huntington's disease.

Objective: The main aim of this study was to investigate the effects of Huntington's disease (HD) on cognitive and affective Theory of Mind (ToM) abilities. The relation of ToM performance and executive functions was also examined. Method: Eighteen HD patients, early in the course of the disease, and 18 healthy volunteers matched for age and educational levels, were given two tasks: a nonverbal cognitive ToM task assessing attribution of intentions to others and a revised version of the 'Reading the Mind in the Eyes' test, which is an affective ToM task assessing the understanding of other people's mental states from their eyes. Participants were also given various executive tests. Results: The two ToM tasks revealed a significant impairment of ToM abilities in HD patients. Executive functioning was impaired in the HD group and ToM performance on the attribution of intentions task was dependent on several executive processes. Conclusions: Our results are consistent with the idea that both cognitive and affective aspects of ToM could be impaired in HD patients, indicating that cortico-subcortical circuits are underlying higher social functions such as ToM. The results are also consistent with the idea that only a few executive mechanisms regulate the ToM abilities we tested in this work. They also provide a basis for the understanding of the disorganized behavior and the breakdown of interpersonal relationships in daily life after HD.

Applying the attractor field model to social cognition: Perceptual discrimination is facilitated, but memory is impaired for faces displaying evaluatively congruent expressions.

A new model of mental representation is applied to social cognition: the attractor field model. Using the model, the authors predicted and found a perceptual advantage but a memory disadvantage for faces displaying evaluatively congruent expressions. In Experiment 1, participants completed a same/different perceptual discrimination task involving morphed pairs of angry-to-happy Black and White faces. Pairs of faces displaying evaluatively incongruent expressions (i.e., happy Black, angry White) were more likely to be labeled as similar and were less likely to be accurately discriminated from one another than faces displaying evaluatively congruent expressions (i.e., angry Black, happy White). Experiment 2 replicated this finding and showed that objective discriminability of stimuli moderated the impact of attractor field effects on perceptual discrimination accuracy. In Experiment 3, participants completed a recognition task for angry and happy Black and White faces. Consistent with the attractor field model, memory accuracy was better for faces displaying evaluatively incongruent expressions. Theoretical and practical implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attention training in individuals with generalized social phobia: A randomized controlled trial.

The authors conducted a randomized, double-blind placebo-controlled trial to examine the efficacy of an attention training procedure in reducing symptoms of social anxiety in 44 individuals diagnosed with generalized social phobia (GSP). Attention training comprised a probe detection task in which pictures of faces with either a threatening or neutral emotional expression cued different locations on the computer screen. In the attention modification program (AMP), participants responded to a probe that always followed neutral faces when paired with a threatening face, thereby directing attention away from threat. In the attention control condition (ACC), the probe appeared with equal frequency in the position of the threatening and neutral faces. Results revealed that the AMP facilitated attention disengagement from threat from pre- to postassessment and reduced clinician- and self-reported symptoms of social anxiety relative to the ACC. The percentage of participants no longer meeting Diagnostic and Statistical Manual (4th ed.) criteria for GSP at postassessment was 50% in the AMP and 14% in the ACC. Symptom reduction in the AMP group was maintained during 4-month follow-up assessment. These results suggest that computerized attention training procedures may be beneficial for treating social phobia. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depression as a predictor of perceived social support and demand: A componential approach using a prospective sample of older adults.

This study examined the relationship of the cognitive, mood, and somatic components of depression on perceptions of social support and social demand among older adults (n = 851) over two years. Factor-analyses confirmed the factor structure of our multicomponential model of depression. Results supported our proposal that interpersonal specificity, as measured by depressive cognition about self and others, is important to predicting changes in perceived support and demand over time. Each component of depression was related to social support and social demand cross-sectionally, whereas only the cognitive component of depression predicted changes in support and demand prospectively. Future research should consider the pathways linking depressive cognition to perceived support and demand. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Return of the ego--Self-referent information as a filter for social prediction: Comment on Karniol (2003).

The protocentrism paradigm of social prediction (R. Karniol, 2003) challenges the egocentrism paradigm tacitly accepted by many researchers. The author reviews the 2 paradigms comparatively by focusing on 3 conceptual and 3 empirical issues. On conceptual grounds, the author suggests that the egocentrism paradigm has been proven useful because of (a) its greater breadth and parsimony, (b) the difficulties in documenting the origin of protocenters, and (c) the indeterminate nature of self-as-distinct tags (which are crucial to protocentrism). On empirical grounds, the author argues that in research on perceptions of self-other similarities, the egocentric process of social projection is well-established. Self-referent knowledge (a) is most readily accessible, (b) receives greater weight in prediction tasks than does other-referent knowledge, and (c) tends to be suppressed only temporarily, with effort, and incompletely.

Effects of alcohol on person perception: A social cognitive neuroscience approach.

The acute effects of alcohol on cognitive processing of expectancy violations were investigated using event-related brain potentials and a cued recall task to index attentional and working memory processes associated with inconsistency resolution. As predicted, expectancy-violating behaviors elicited larger late positive potentials (LPP) and were recalled better than expectancy-consistent behaviors. These effects were moderated by alcohol and the valence of initial expectancies. For placebo group participants, positive targets performing negative behaviors elicited the largest LPP responses and were recalled best. For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. These findings suggest that alcohol does not globally impair working memory processes in person perception but instead changes the nature of valenced information processing. Findings are discussed in the context of alcohol's effects on working memory processes, reward sensitivity, and the prefrontal cortical structures thought to mediate them.
