Sex-related differences in chromatic sensitivity

Abstract

Permanent repository link AbstractGenerally women are believed to be more discriminating than men in the use of colour names and this is often taken to imply superior colour vision. However, if both Xchromosome linked colour deficient males (~8%) and females (<1%) as well as heterozygote female carriers (~15%) are excluded from comparisons, then differences between men and women in red-green colour discrimination have been reported as not being significant (e.g., Pickford, 1944;Hood et al., 2006). We re-examined this question by assessing the performance of 150 males and 150 females on the Colour Assessment and Diagnosis (CAD)test (Rodriguez-Carmona, 2005). This is a sensitive test that yields small colour detection thresholds. The test employs direction-specific, moving, chromatic stimuli embedded in a background of random, dynamic, luminance contrast noise. A four-alternative, forced-choice

Gender differences in colour naming

“…In particular, female observers revealed larger Rayleigh anomaloscope matches (Rodríguez-Carmona, Sharpe, Harlow and Barbur, 2008) with a range of unique reds about twice as wide as for male observers (Kuehni, 2001). In colour-discrimination tasks, males were found to have a broader range of poorer discrimination in the middle of the spectrum (530-570 nm) compared to females (Abramov, Gordon, Feldman and Chavarga, 2012).…”

“…These differences are suggested to reflect genetic variation in the opponent system responses (Kuehni, 2001) or heterozygosity in Xchromosome allele genes coding for cone photopigments common among females (Rodríguez-Carmona et al, 2008).…”

Does gender and experience influence shade matching quality?

“…11 When color assessment and diagnosis test was performed on 150 color normal males and the same number of color normal females, no significant gender-related difference was recorded. 12 Several dentistry-related studies offered evidence on nonsignificance of differences in shade matching results between color normal females and males. [8][9][10][13][14][15] In addition, it was shade matching results and vice versa.…”

S100β Protein Expression: Gender- and Age-Related Daily Changes

“…Corroborating the intriguing gender differences in S100b expression in brain slices or hippocampal layers are other anatomical, physiological, behavioral, and cognitive findings reinforcing gender differences [34][35][36]. Comparisons of momentum interactions in the EEG revealed gender and regional cortical differences in morning-evening sensitivity at the frontal and temporal lobes.…”
