Abstract

Recently research has shifted from examining discrete categories (e.g. letters) to continuous categories (e.g. colours). While studies have shown that stimuli specific expertise influence discrete categories, there are little research into how it influences continuous categories.
The current study comprises of a whole report experiment with two conditions: discrete and continuous. We divided participants into two groups based on the degree of colour expertise, normal colour expertise and colour experts. By varying stimulus exposure durations, we can fit data using the TVA in order to isolate specific components of attention like visual short-term memory capacity (K), speed of processing (C), and the threshold of perception (t0). Results reveal no significant group differences in the discrete letter condition, but that colour expertise improve K in the continuous category, leaving C and t0 unaffected, indicating that continuous categories improve from expertise similar to discrete.
