Emotion and magnitude perception: number and length bisection

Emotion and magnitude perception: number and length bisection

Studies of the effect of emotional stimuli on time perception have shown that a threatening stimulus produces a temporal lengthening effect compared to a non-threatening stimulus. In order to better understand the mechanisms underlying this emotion-related time distortion, the present study examined distortions in the judgment of other quantities - number and length - under the same emotional c...

A common metric magnitude system for the perception and production of numerosity, length, and duration

Numerosity, length, and duration processing may share a common functional mechanism situated within the parietal cortex. A strong parallelism between the processing of these three magnitudes has been revealed by similar behavioral signatures (e.g., Weber-Fechner's law, the distance effect) and reciprocal interference effects. Here, we extend the behavioral evidence for a common magnitude proces...

Facial feedback and emotion perception

Autism: tactile perception and emotion.

BACKGROUND For many years, and especially since Waynbaum and Wallon, psychology and psychopathology have dealt with cognitive perception, but have had little to do with the affective qualities of perception. Our aim was to study the influence of the sensory environment on people with autism. METHOD Several experiments were carried out using different forms of tactile stimulation (passive and ...

Interference between number processing and line bisection: a methodology.

It is usually thought that numbers are represented on a "mental number line" on which the progression of smaller to larger numbers occurs from left to right suggesting a spatial representation of numbers. Reciprocally, number processing has been shown to influence space representation [Fischer, M. (2001). Number processing induces spatial performance biases. Neurology, 822-826]. Specifically, i...
