Do masks cover more than just a face? A study on how facemasks affect the perception of emotional expressions according to their degree of intensity
The objective of the present study was to evaluate the impact of facemasks through an emotion categorization task using morphs ranging from a neutral face and an expressive face (anger, disgust, fear, happiness, and sadness) (from 0% neutral to 100% expressive in 20% steps). Our results revealed a strong impact of facemasks on the recognition of expressions of disgust, happiness, and sadness, resulting in a decrease in performance and an increase in misinterpretations, both for low and high levels of intensity. In contrast, the recognition of anger and fear, as well as neutral expression, was found to be less impacted by m...

Stimulus intensity modulates perceived tactile distance
Perception. 2023 Sep 11:3010066231200434. doi: 10.1177/03010066231200434. Online ahead of print.ABSTRACTSeveral features of tactile stimuli modulate the perceived distance between touches. In particular, distances are perceived as farther apart when the time interval between them is longer, than when it is shorter. Such effects have been interpreted as a form of 'psychological relativity', analogous to Einstein's conception of a four-dimensional space-time. We investigated whether similar effects occur for stimulus features other than time, specifically stimulus intensity. We hypothesised that perceived distance would be i...

Does a concurrent motor process influence representational momentum?
Perception. 2023 Sep 8:3010066231194955. doi: 10.1177/03010066231194955. Online ahead of print.ABSTRACTWhether the direction of a hand motion that is congruent or incongruent with a concurrent target motion can influence representational momentum for that target was examined. Participants viewed a leftward or rightward moving target while moving their hand rightward, leftward, or not moving their hand. Prior studies of mental rotation found that congruency or incongruency of the direction of mental rotation and the direction of a concurrent physical rotation of a stimulus influenced mental rotation. As mental rotation and ...

Are the directions of both eyes integrated before or after the perception of direct gaze? Evidence from simulated mild strabismus
Perception. 2023 Sep 3:3010066231194216. doi: 10.1177/03010066231194216. Online ahead of print.ABSTRACTThe cone of gaze is a looker's range of gaze directions that is accepted as direct by an observer. The present research asks how the condition of mild strabismus, that is, when the two eyes point in slightly different directions, influences the cone of gaze. Normally, both eyes are rotated in a coordinated manner such that both eyes are directed to the same fixation point. With strabismus, there are two fixation points, and, therefore, two directions into which the two eyes point. This raises the question of the direction...

Face inversion effect on perceived cuteness of infant faces
Perception. 2023 Sep 4:3010066231198417. doi: 10.1177/03010066231198417. Online ahead of print.ABSTRACTResearch has demonstrated that attractiveness evaluations of adult faces were less accurate when faces were inverted than upright. It remains unknown, however, whether a similar effect applies to perceived cuteness of infants, which is assumed to be based on elemental facial features called the "baby schema." In this research, we studied the face inversion effect on perceived cuteness of infant faces in a rating task and a two-alternative forced-choice (2AFC) task. We also examined beauty as a control dimension. Although ...
