Motion: Threshold for First- and Second-order Movement with Age

Description

These data were reported by Thibault et al (2007) (their Figure 4) and provide developmental data on the contrast modulation threshold for detection of a moving stimulus for two kinds of motion, called First-order (or luminance based) and Second-order (contrast based).

Usage

Data kindly provided by F. Vital-Durand.

Details

The data were collected using preferential-looking techniques. Percent contrast varies between 0 and 100.
