The effect of contrast adaptation on briefly presented stimuli
Wilson and Humanski (1993) have recently reported evidence that adapting to low temporal frequency sinewave gratings yields little threshold elevation for briefly presented test stimuli. We postulated that brief stimuli may be detected by a transient channel which would be minimally affected by a low temporal frequency adapting pattern. We therefore measured the effect of adaptation on briefly ...
متن کاملIndividual Differences in Infants’ Recognition of Briefly Presented Visual Stimuli
Infants’ recognition memory has been shown to be related to individual differences in look duration and level of heart period variability. This study examined the effect of individual differences in these 2 measures on infants’ recognition of briefly presented visual stimuli using a paired-comparison recognition-memory paradigm. A sample of 35 full-term infants was studied longitudinally at 14,...
متن کاملContributions of fixational eye movements to the discrimination of briefly presented stimuli.
Although it is known that images tend to disappear when they are stabilized on the retina for tens of seconds or minutes, the possible functions of fixational movements during the brief periods of visual fixation that occur during natural viewing remain controversial. Studies that investigated the retinal stabilization of stimuli presented for less than a few seconds have observed neither decre...
متن کاملLuminance coding of briefly presented stimuli in area 17 of the rhesus monkey.
1. Single cells in area 17 of the alert rhesus monkey were classified according to their sensitivity to variations in stimulus orientation, color, and direction of movement. The sensitivity of the cells to stimulus luminance was then tested using moving bars and large stationary spots presented for 500 ms. The luminance of the stimulus was varied over trials; background luminance was kept const...
متن کاملAttention affects the recognition of briefly presented visual stimuli in infants: an ERP study.
This study examined the effect of attention in infants on the ERP changes occurring during the recognition of briefly presented visual stimuli. Infants at ages 4.5, 6 and 7.5 months were presented with a Sesame Street movie that elicited periods of attention and inattention, and computer-generated stimuli were presented overlaid on the movie for 500 ms. One stimulus was familiar to the infants ...
