The effect of exposure time upon perceived size

S R Cobb, C Cole, M T Rainey

The British Journal of Physiological Optics

|January 1, 1978

Summary

Exposure duration influences perceived size. Shorter exposure times on a tachistoscope led to altered size perception in participants, suggesting time is a key factor in visual size judgments.

Area of Science:

Visual Perception
Psychophysics

Background:

Understanding visual perception is crucial in fields like psychology and human-computer interaction.
Previous research has explored various factors influencing size perception, but the specific role of brief exposure durations requires further investigation.

Purpose of the Study:

To investigate the effect of tachistoscopic exposure time on the accurate perception of object size.
To determine if varying exposure durations alter an individual's ability to match a standard circle's perceived size.

Main Methods:

Ten subjects were presented with a standard filled circle using a tachistoscope for exposure durations ranging from 100 to 1000 milliseconds.
Participants then selected a comparison circle that appeared to be the same size from a set of eleven circles with varying angular subtenses.
The experiment measured the accuracy of size matching under different exposure conditions.

Main Results:

A significant relationship was observed between the exposure time of the visual stimulus and the accuracy of size perception.
Participants' ability to correctly identify the matching circle size was influenced by the duration the standard circle was displayed.
The results suggest that brief exposure times can lead to distortions in perceived size.

Conclusions:

Exposure duration is a critical variable affecting the perception of visual size.
Tachistoscopic studies demonstrate that the temporal aspect of visual input plays a role in psychophysical judgments of object dimensions.
