TLDR
A novel psychophysical approach is taken to directly compare human face and object processing in the same experiment, with face processing broken into two categories: variant properties and invariant properties as they were tested using facial expressions of emotion and gender, respectively.Abstract:
To distinguish between high-level visual processing mechanisms, the degree to which holistic processing is involved in facial identity, facial expression, and object perception is often examined through measuring inversion effects. However, participants may be biased by different experimental paradigms to use more or less holistic processing. Here we take a novel psychophysical approach to directly compare human face and object processing in the same experiment, with face processing broken into two categories: variant properties and invariant properties as they were tested using facial expressions of emotion and gender, respectively. Specifically, participants completed two different perceptual discrimination tasks. One involved making judgments of stimulus similarity and the other tested the ability to detect differences between stimuli. Each task was completed for both upright and inverted stimuli. Results show significant inversion effects for the detection of differences in facial expressions of emotion and gender, but not for objects. More interestingly, participants exhibited a selective inversion deficit when making similarity judgments between different facial expressions of emotion, but not for gender or objects. These results suggest a three-way dissociation between facial expression of emotion, gender, and object processing.read more

TL;DR: It is suggested that AD patients have deficits in higher-level visual processes, more specifically at perceiving individual faces, a function that relies on holistic representations specific to upright face stimuli.

Further evidence of early development of attention to dynamic facial emotions: Reply to Grossmann and Jessen
TL;DR: It is likely that infants' enhanced attention to fear in this study was indeed a response to emotions rather than a reaction to arbitrary low-level stimulus features and underscores the need to find mechanisms that engender the development of emotion knowledge early in life.

Attentional allocation to task-irrelevant fearful faces is not automatic: experimental evidence for the conditional hypothesis of emotional selection.
TL;DR: Rather than automatic, attentional allocation to irrelevant fearful faces proved conditional to the explicit relevance of fearful expressions to top-down search goals.

Face pareidolia in the brain: Impact of gender and orientation.
TL;DR: In this article, a set of Face-n-Thing images was used to examine how face tuning alters with changing display orientation, and whether it is affected by observers' gender.

An argument for basic emotions
TL;DR: This work has shown that not only the intensity of an emotion but also its direction may vary greatly both in the amygdala and in the brain during the course of emotion regulation.

Understanding face recognition
Vicki Bruce,Andrew W. Young +1 more
TL;DR: A functional model is proposed in which structural encoding processes provide descriptions suitable for the analysis of facial speech, for analysis of expression and for face recognition units, and it is proposed that the cognitive system plays an active role in deciding whether or not the initial match is sufficiently close to indicate true recognition.

TL;DR: The results lend empirical support for the validity and reliability of this set of facial expressions as determined by accurate identification of expressions and high intra-participant agreement across two testing sessions, respectively.
