The effect of instructions and response format on smile judgement.

Our study examined the role of instructions, response type, and definition on the judgement of enjoyment and nonenjoyment smiles. Participants viewed symmetric Duchenne, non-Duchenne, and asymmetric smiles. They were instructed to judge the happiness, authenticity, and sincerity of the smiles using either Likert scales or a dichotomous response type.

A category contingent aftereffect for faces labelled with different religious affiliation is seen 7 days after adaptation.

Visual adaptation occurs after a prolonged exposure to a stimulus. The duration of aftereffects differs across stimuli type, and face aftereffects may be especially long lasting. The current study investigates adaptation decay of category contingent opposing aftereffects.

Opposing aftereffects between a White male face set and a diverse face set.

Opposing aftereffects have been observed for faces categorized by gender, race, and age. In order to form opposing aftereffects, it appears that the two face sets must be both physically distinct and differ in terms of social meaning. The current study tests whether (1) a face set that is diverse with respect to sex and race can produce a coherent aftereffect and (2) whether this diversity itself is socially meaningful enough to support opposing aftereffects.

The development of template-based facial expression perception from 6 to 15 years of age.

When perceiving emotional facial expressions, adults use a template-matching strategy, comparing the perceived face with a stored representation. A rejection of unnaturally exaggerated faces is characteristic of this strategy because the exaggerated expressions do not match the stored template. In contrast, a rule-based perceptual strategy (e.

Distinct Biological Motion Perception in Autism Spectrum Disorder: A Meta-Analysis.

If neurotypical people rely on specialized perceptual mechanisms when perceiving biological motion, then one would not expect an association between task performance and IQ. However, if those with ASD recruit higher order cognitive skills when solving biological motion tasks, performance may be predicted by IQ. In a meta-analysis that included 19 articles, we found an association between biological motion perception and IQ among observers with ASD but no significant relationship among typical observers.

When pictures take away from the message: An examination of young adults' attention to texting and driving advertisements.

This study examined eye-movement patterns of young adults, while they were viewing texting and driving prevention advertisements, to determine which format attracts the most attention. As young adults are the most at risk for this public health issue, understanding which format is most successful at maintaining young adults' attention is especially important. Participants viewed nondriving, general distracted driving, and texting and driving advertisements.
