Investigating the Early Stages of Person Perception: The Asymmetry of Social Categorization by Sex vs. Age

Early perceptual operations are central components of the dynamics of social categorization. The wealth of information provided by facial cues presents challenges to our understanding of these early stages of person perception. The current study aimed to uncover the dynamics of processing multiply categorizable faces, notably as a function of their gender and age. Using a...

Hand movements reveal the time-course of shape and pigmentation processing in face categorization

Jonathan B. Freeman Nalini Ambady Although the roles of shape and pigmentation cues in face categorization have been studied in detail, the time-course of their processing has remained elusive. We

Does context matter in evaluations of stigmatized individuals? An fMRI study

The manner in which disparate affective responses shape attitudes toward other individuals has received a great deal of attention in neuroscience research. However, the malleability of these affective responses remains largely unexplored. The perceived controllability of a stigma (whether or not the bearer of the stigma is perceived as being responsible for his or her condition...

How does the brain regulate negative bias to stigma?

The current study uses functional magnetic resonance imaging (fMRI) to examine whether regulating negative bias to stigmatized individuals has a unique neural activity profile from general emotion regulation. Participants were presented with images of stigmatized (e.g. homeless people) or non-stigmatized (e.g. a man holding a gun) social targets while undergoing fMRI and were...

Looking the Part: Social Status Cues Shape Race Perception

It is commonly believed that race is perceived through another's facial features, such as skin color. In the present research, we demonstrate that cues to social status that often surround a face systematically change the perception of its race. Participants categorized the race of faces that varied along White–Black morph continua and that were presented with high-status or low...

The Neural Basis of Categorical Face Perception: Graded Representations of Face Gender in Fusiform and Orbitofrontal Cortices

Face gender, like many other things, is perceived categorically: Subjective perceptions are distorted toward the categories, male or female, and the objective gradiency inherent across faces is partially lost. The neural basis of such categorical face perception remains virtually unknown. Participants passively viewed faces whose sexually dimorphic content was morphed...

Amygdala responses to averted vs direct gaze fear vary as a function of presentation speed

We examined whether amygdala responses to rapidly presented fear expressions are preferentially tuned to averted vs direct gaze fear and conversely whether responses to more sustained presentations are preferentially tuned to direct vs averted gaze fear. We conducted three functional magnetic resonance imaging (fMRI) studies to test these predictions including: Study 1: a block...

Us and them: Memory advantages in perceptually ambiguous groups

Ingroup advantages and outgroup deficits in perception and memory are well-established in research on race, gender, and other ostensibly identifiable social categories. The present study extended this research to a social category that is not as perceptually apparent: male sexual orientation. Consistent with hypotheses, an interaction of participant sexual orientation and image...

Culture, gaze and the neural processing of fear expressions

The direction of others’ eye gaze has important influences on how we perceive their emotional expressions. Here, we examined differences in neural activation to direct- versus averted-gaze fear faces as a function of culture of the participant (Japanese versus US Caucasian), culture of the stimulus face (Japanese versus US Caucasian), and the relation between the two. We employed...
