Task-dependent pupillary responses to glossiness and attractiveness judgments

This study examines how task-dependent pupillary responses differ between glossiness and attractiveness judgments of the same images, revealing distinct temporal profiles of sensory and affective processing.

What makes an angry face uncomfortable? Distinct contributions of facial expression, interpersonal distance, facial stimulus type, and gaze in virtual reality

The paper investigates factors contributing to discomfort from angry faces in virtual reality, finding that distance and gaze direction significantly influence discomfort beyond perceived anger.

The congruency between anger intensity and reddish facial color modulates the early posterior negativity (EPN)

This study shows that reddish angry faces increase the EPN amplitude with higher emotion intensity compared to original and green faces.

Direction-dependent bias in the perceived approach speed and its implications for robot motion design

The paper demonstrates a direction-dependent bias in perceived approach speed of objects and suggests its implications for robot motion design.

Human trust and emotion in the context of collision avoidance with an autonomous mobile robot: An investigation of predictability and smoothness in virtual reality

This study investigates how predictability and smoothness of autonomous mobile robot motion affect human trust and emotion in virtual reality collision avoidance scenarios.

Material perception relies on context-dependent active sensing strategies

The paper shows that humans use context-dependent active sensing strategies, like head and hand movements, to better discriminate visually ambiguous materials in virtual reality.

Human behavior and comfort during load carrying to autonomous mobile robot

This study examines human behavior and comfort when interacting with autonomous mobile robots during package delivery, finding that closer approach increases comfort but requires careful speed control.

The glare illusion in individuals with schizophrenia

This study examines how individuals with schizophrenia perceive the glare illusion, finding they are more susceptible to it than controls, though this is not linked to symptom severity.

Illuminating the Unconscious: Physical and Perceived Brightness in Cognitive Processing

This study examines how physical and perceived brightness influence breakthrough time under continuous flash suppression, finding that unconscious processing of brightness illusions occurs without expediting awareness.

Dynamic vs. Static Facial Color Changes: Evidence for Terminal Color Dominance in Expression Recognition

This study examines how dynamic vs. static facial color changes affect emotion perception, finding that final reddish color, not dynamics, influences anger perception.

Interaction between facial expression and color in modulating ERP P3

The paper investigates how facial expression and color interact to modulate ERP P3 amplitudes during selective attention tasks, finding that red angry faces elicit greater P3 responses than red neutral faces.

Facial expression recognition is modulated by approach-avoidance behavior

This study shows that approach-avoidance behaviors influence facial expression recognition, revealing a reverse causal relationship.

Visual cues for moisture perception of facial skin: Enhancing high-frequency components of skin lightness increases perceived dryness

Spatial modulation of facial expression: enhanced recognition of faces behind the observer

This study shows that facial expression recognition is enhanced when faces are behind the observer, with anger being more detectable than happiness, suggesting a threat detection mechanism.

Glossiness perception and its pupillary response

The paper investigates how glossiness perception affects pupillary response by comparing original and shuffled images with controlled luminance.

Waist rotation angle as an indicator of probable human collision avoidance direction for autonomous mobile robots

This study investigates human avoidance behavior toward autonomous mobile robots and finds that waist rotation angle predicts avoidance direction.
