Checkerboards contain fundamental two-dimensional Fourier components oriented 45° from the edges of individual checks. Previous studies have shown that contingent color aftereffects following adaptation to chromatic checkerboard stimuli were associated with the fundamental components rather than the edges, In the present experiments, we measured contingent color aftereffects, using the method of constant stimuli, after subjects adapted to unfiltered checkerboards and checkerboards with the fundamental Fourier components removed. The adaptation stimuli were magenta (or green) squares and green (or magenta) diamonds; the test stimuli were vertical or oblique sine-wave gratings with different saturations, After adaptation to unfiltered checkerboards, aftereffects contingent on the fundamental components were obtained. In contrast, after adaptation to filtered stimuli, aftereffects of smaller magnitude were found to be aligned with the edges. The data support the previous findings of spatial-frequency-contingent color after-effects with checkerboard adaptation stimuli and indicate that the aftereffects can be associated with edges if the fundamental components of adaptation stimuli are removed by spatial filtering. We reexamined the possibility of color aftereffects induced by imagery of checkerboards. Contrary to the previous reports, no significant aftereffects were obtained. 相似文献

In recent years, sexual harassment has become more acknowledged in many developed countries. However, in East Asian culture, it is a sensitive and controversial topic upon which few scholars have focused. The current research aimed to explore whether the relationship between feminist identity and perception of sexual harassment was affected by target’s traditional or nontraditional gender stereotypicality and types of sexual harassment (unwanted sexual attention or gender harassment) among Chinese working women. The participants were 424 heterosexual women, aged 18 to 71 years-old (mdn?=?31), who completed surveys that assessed their feminist Active Commitment and perception of sexual harassment after reading a randomly assigned sexual harassment scenario. Women with higher scores on Active Commitment were more aware of both types of sexual harassment, and participants’ perception of unwanted sexual attention was significantly stronger than their perception of gender harassment. In addition, the types of targets and types of sexual harassment moderated the relationship between Active Commitment and the perception of sexual harassment. Our findings highlight the importance of feminist identity for the perception of sexual harassment and suggest that improving gender equality and feminist education is very important for enhancing the perception of sexual harassment.
