Spatial frequencies affect cuteness perception of infant faces
Cuteness perception is a basic function in social interactions. Most studies focus on the impact of facial elemental features on cuteness ratings, but there are many factors that affect cuteness perception. Spatial frequency (SF) is one of the most important parameters in studies on faces. However, few studies have investigated the impact of SFs on cuteness perception. In this study, 16 images of infant faces with four cuteness levels were select…
Improving Visual Working Memory With Training on a Tactile Orientation Sequence Task in Humans
Working memory refers to the cognitive capacity to temporarily store and manipulate information from multiple sensory domains. Recent studies have shown that cognitive training can improve performance in both visual working memory and tactile working memory tasks. However, it is still unclear whether the effects of training can be transferred from one sensory modality to another. The current study assessed whether the training effect of the tacti…
A linkage of chromatic and achromatic cues in neon color effect
Neon color effect consists of two phenomenal aspects of brightness/darkness enhancement and color bleeding. The spectral properties of these two aspects were determined by threshold measurements, using the Ehrenstein pattern configuration made up of elements of different colors. The results indicate that the Ehrenstein brightness illusion is mediated by the achromatic system and the neon bleeding effect by the opponent-color system, and that both…
Long-Term Drifts in Individual Observers' Unique-Hue Spectral Loci
Unique-hue spectral loci were measured under conditions of neutral adaptation as part of a study of hue-response recovery following chromatic adaptation. Four observers adjusted the wavelength of the test-field until it appeared to be neither yellow nor blue (unique green) or neither red nor green (unique yellow and blue) in randomized sessions. The results showed that there were marked individual differences and long-term drifts in the unique-hu…
