Examinations of identity invariance in facial expression adaptation

Faces provide a wealth of information essential to social interaction, including both static features, such as identity, and dynamic features, such as emotional state. Classic models of face perception propose separate neural-processing routes for identity and facial expression (Bruce & Young, 1986), but more recent models suggest that these routes are not independent of each other (Calder & Young, 2005). Using a perceptual adaptation paradigm in the present study, we attempted to further examine the nature of the relation between the neural representations of identity and emotional expression. In Experiment 1, adaptation to the basic emotions of anger, surprise, disgust, and fear resulted in significantly biased perception away from the adapting expression. A significantly decreased aftereffect was observed when the adapting and the test faces differed in identity. With a statistical model that separated surface texture and reflectance from underlying expression geometry, Experiment 2 showed a similar decrease in adaptation when the face stimuli had identical underlying prototypical geometry but differed in the static surface features supporting identity. These results provide evidence that expression adaptation depends on perceptual features important for identity processing and thus suggest at least partly overlapping neural processing of identity and facial expression.     

Truck Driver or Nurse? The Impact of Gender Roles and Occupational Status on Children’s Occupational Preferences

Three experiments examined how US children perceive occupational status and gender roles. In Experiment 1, 107 6-to-12-year-olds rated the status and gender roles of 54 occupations. Feminine occupations were underrepresented among the perceived high status jobs. In Experiment 2, 28 6-to-8-year-olds, and in Experiment 3, 36 9-to-12-year-olds, reported their preferences for equally high status masculine and feminine occupations and low status masculine and feminine occupations. In both experiments, girls preferred feminine to masculine occupations and status only affected preferences for masculine occupations. The younger boys’ preferences were based on both variables, whereas older boys’ preferences were based on status. These findings imply that occupational status may influence boys’ vocational preferences more than pressure to conform to masculine gender roles.     

Customer service providers' attitudes relating to customer service and customer satisfaction in the customer-server exchange

The authors proposed and tested a model describing the relationship between customer service providers' perceptions and attitudes toward their service-related duties and their customers' perceptions of satisfaction with their service experiences. Results indicated that the perception of having standards for service delivery in an organization is strongly related to line-level employees' perceptions of support from coworkers and supervisors. Perceived support from coworkers was significantly related to service providers' customer orientation, whereas perceived support from supervisors showed a weaker relationship to a customer orientation. Ultimately, service providers' customer orientation was strongly related to customers' satisfaction with service. Finally, a set of post hoc analyses indicated that coworker and supervisory support explained a greater proportion of incremental variance in the model than did perceived organizational support alone.     

The impact of rape: Social support as a moderator of stress

This study investigated 25 victims' reactions to sexual assault and the role of social support in their subsequent adjustment. Victims were interviewed 3 months after the assault to gather information about the assault, the type of support they received, and the effects of the assault as measured by two scales of psychological stress: Impact of Events scale and SCL-90-R. Our major findings were that (a) victim's scale scores were significantly elevated, reflecting the considerable distress they were still experiencing; (b) there were significant differences in the availability of support from specific categories of people (e.g., police received significantly high ratings, whereas physicians' ratings were significantly low); (c) the amount of perceived support varied with the stressfulness of the assault; (d) however, contrary to initial hypotheses, the amount of overall support did not predict subsequent adjustment; (e) support from physicians did correlate significantly with both scales of psychological adjustment.     

Decoupling Children’s Gender-based In-Group Positivity from Out-Group Negativity

In the current study we attempted to determine whether children’s gender-based intergroup biases reflect positive attitudes toward the in-group and/or negative attitudes toward the out-group. Third through fifth grade children were asked to determine whether positive and negative traits described boys, girls, both genders, or nobody. This methodology allowed for separate evaluation of in-group favoritism and out-group derogation. Girls and children who perceived their gender as important viewed their in-group as having more positive than negative attributes and more positive and less negative attributes than the out-group. Boys and children who viewed gender as less important viewed both genders as having more positive than negative attributes. These results support Brewer’s (Journal of Social Issues 55:429–444, 1999) claim that in-group love and out-group hate are not reciprocally related.     

Perceiving individuals and groups: expectancies, dispositional inferences, and causal attributions

Two experiments investigated differences in forming impressions of individual and group targets. Experiment 1 showed that when forming an impression of an individual, perceivers made more extreme trait judgments, made those judgments more quickly and with greater confidence, and recalled more information than when the impression target was a group. Experiment 2 showed that when participants were forming an impression of an individual, expectancy-inconsistent behaviors spontaneously triggered causal attributions to resolve the inconsistency; this was not the case when the impression target was a group. Results are interpreted as reflecting perceivers' a priori assumptions of unity and coherence in individual versus group targets.     

Angry, disgusted, or afraid? Studies on the malleability of emotion perception

ABSTRACT— Current theories of emotion perception posit that basic facial expressions signal categorically discrete emotions or affective dimensions of valence and arousal. In both cases, the information is thought to be directly "read out" from the face in a way that is largely immune to context. In contrast, the three studies reported here demonstrated that identical facial configurations convey strikingly different emotions and dimensional values depending on the affective context in which they are embedded. This effect is modulated by the similarity between the target facial expression and the facial expression typically associated with the context. Moreover, by monitoring eye movements, we demonstrated that characteristic fixation patterns previously thought to be determined solely by the facial expression are systematically modulated by emotional context already at very early stages of visual processing, even by the first time the face is fixated. Our results indicate that the perception of basic facial expressions is not context invariant and can be categorically altered by context at early perceptual levels.     

Children's Perception of Gender-Based Illusory Correlations: Enhancing Preexisting Relationships Between Gender and Behavior

The purpose of this study was to examine whether children would perceive an illusory correlation between gender and behavior above and beyond the actual relationship between the variables in the stimuli. Second and fourth grade children were presented with a series of pictures of men and women performing gender stereotypic, counter-stereotypic, and neutral behaviors. One gender (the high frequency gender) performed each behavior twice as often as the other gender. The children made higher frequency estimates for stimuli that matched their expectancies than for stimuli that were neutral or counter to their expectations. Further, they perceived a stronger relationship between gender and behavior for stimuli that were stereotypic for the high frequency gender than for neutral or counter-stereotypic stimuli.
