“…On the other hand, participants' RTs did increase with angular distance (see Supplemental Figures 5A and 5B), though such effects could instead reflect difficulty across trials (Pramod et al, 2022). It is also possible that our task induced some degree of implied motion (Kourtzi & Kanwisher, 2000;Li et al, 2021), which could account for the relation between RT and angular distance, rather than partial simulation per se.…”

How do humans judge physical stability? A prevalent account emphasizes the mental simulation of physical events implemented by an intuitive physics engine in the mind. Here we test the extent to which the perceptual features of object geometry are sufficient for supporting judgments of falling direction. In all experiments, adults and children judged the falling direction of a tilted object and, across experiments, objects differed in the geometric features (i.e., geometric centroid, object height, base size and/or aspect ratio) relevant to the judgment. Participants’ performance was compared to computational models trained on geometric features, as well as a deep convolutional neural network (ResNet-50), none of which incorporated mental simulation. Adult and child participants’ performance was well fit by models of object geometry, particularly the geometric centroid. ResNet-50 also provided a good account of human performance. Altogether, our findings suggest that object geometry is sufficient for judging the falling direction of tilted objects, independent of mental simulation.

“…The other reason was that in the psychophysical experiment, we tried to measure the luminance contrast sensitivity using psychometric functions in order to obtain the magnitude of the luminance signal. Although a psychometric function can be obtained by a complex visual stimulus (Ueda et al, 2018;Li et al, 2021), in our case we were afraid we would not be able to obtain the magnitude of the luminance signal from the function. Therefore, we thought it would be better to make the visual stimulus simple because we did not have a specific model to estimate the magnitude of the luminance signal from the psychometric functions obtained from the visual stimulus with this ellipse background pattern.…”

The results of psychophysical studies suggest that color in a visual scene affects luminance contrast perception. In our brain imaging studies we have found evidence of an effect of chromatic information on luminance information. The dependency of saturation on brain activity in the visual cortices was measured by functional magnetic resonance imaging (fMRI) while the subjects were observing visual stimuli consisting of colored patches of various hues manipulated in saturation (Chroma value in the Munsell color system) on an achromatic background. The results indicate that the patches suppressed luminance driven brain activity. Furthermore, the suppression was stronger rather than weaker for patches with lower saturation colors, although suppression was absent when gray patches were presented instead of colored patches. We also measured brain activity while the subjects observed only the patches (on a uniformly black background) and confirmed that the colored patches alone did not give rise to differences in brain activity for different Chroma values. The chromatic information affects the luminance information in V1, since the effect was observed in early visual cortices (V2 and V3) and the ventral pathway (hV4), as well as in the dorsal pathway (V3A/B). In addition, we conducted a psychophysical experiment in which the ability to discriminate luminance contrast on a grating was measured. Discrimination was worse when weak (less saturated) colored patches were attached to the grating than when strong (saturated) colored patches or achromatic patches were attached. The results of both the fMRI and psychophysical experiments were consistent in that the effects of color were greater in the conditions with low saturation colors.

“…Word distance between the two words were varied such that the two words were either close or distant, via manipulating semantic (Experiment 1) or phonological (Experiment 2) similarity ( Hillinger, 1980 ; Rouibah et al, 1999 ; Zhou and Marslen-Wilson, 2000 ). We used the classic temporal bisection task ( Penney et al, 2008 ; Matthews and Meck, 2016 ; Li et al, 2021 ) to examine the subjective temporal distance. In this task, participants are first presented with multiple “short” and “long” anchor time intervals, followed by a test phase in which they judge a set of intermediate intervals (aka, the probe intervals) as being closer to the “short” or “long” anchor intervals.…”

Word Distance Affects Subjective Temporal Distance

The kappa effect is a well-reported phenomenon in which spatial distance between discrete stimuli affects the perception of temporal distance demarcated by the corresponding stimuli. Here, we report a new phenomenon that we propose to designate as the lexical kappa effect in which word distance, a non-magnitude relationship of discrete stimuli that exists in the lexical space of the mental lexicon, affects the perception of temporal distance. A temporal bisection task was used to assess the subjective perception of the time interval demarcated by two successively presented words. Word distance was manipulated by varying the semantic (Experiment 1) or phonological (Experiment 2) similarity between the two words. Results showed that the temporal distance between the two words was perceived to be shorter when the corresponding two words were lexically closer. We explain this effect within the internal clock framework by assuming faster detection of the word that terminated timing when it is preceded by a semantically or phonologically similar word.
