Emotional information influences our bodily experiences according to the space-valence metaphor (positive/negative is up/down). In the present study, we examined whether visible and invisible emotional stimuli could also modulate voluntary action. After observing an emotional image (e.g., positive, neutral, or negative), participants used a joystick to… (More)
Perceived duration of a moving stimulus increases with the speed of the motion. However, a recent study found that the perceived duration of a decelerating stimulus was longer than that of an accelerating one, even though their averaged speed was identical (Matthews 2011 Journal of Experimental Psychology: Human Perception and Performance 37 1617-1627). We… (More)
When faced with a novel food, multisensory information that includes appearance and smell is a very important cue for preference, categorization, and the decision of whether or not to eat it. We elucidated whether olfactory information leads to biased visual categorization of and preference for fruits, even when odors are presented subliminally. We employed… (More)
While viewing a large vertically moving sinusoidal luminance grating, the perception of upward self-motion (vection) was modulated by positive sounds (e.g., a baby's laughter). This may be because positive emotion and the spatial metaphor of vertical directions were unified in the mind.
Upward and downward motor actions influence subsequent and ongoing emotional processing in accordance with a space-valence metaphor: positive is up/negative is down. In this study, we examined whether upward and downward motor actions could also affect previous emotional processing. Participants were shown an emotional image on a touch screen. After the… (More)
Numerical representations influence temporal processing. Previous studies have consistently shown that larger numbers are perceived to last longer than smaller ones. However, whether this effect is modulated by the absolute or relative magnitudes of the numbers has yet to be fully understood. Here, participants observed single- and double-digit Arabic… (More)
Artificial objects often subjectively look eerie when their appearance to some extent resembles a human, which is known as the uncanny valley phenomenon. From a cognitive psychology perspective, several explanations of the phenomenon have been put forth, two of which are object categorization and realism inconsistency. Recently, MacDorman and Chattopadhyay… (More)
The present study demonstrated that friction cues for target motion affect time-to-contact (TTC) estimation. A circular target moved in a linear path with a constant velocity and was gradually occluded by a static rectangle. The target moved with forward and backward spins or without spin. Observers were asked to respond at the time when the moving target… (More)
