Pupillary constriction to darkness.
Patients with congenital achromatopsia and congenital stationary night blindness have been known to show a transient pupillary constriction to darkness. We examined 50 normal subjects and 108 patients with retinal and optic nerve dysfunction to see if any had an initial pupillary constriction to darkness. We used a new infrared television apparatus. Four patients with congenital stationary nigh...
متن کاملIntrasaccadic perception triggers pupillary constriction
It is commonly believed that vision is impaired during saccadic eye movements. However, here we report that some visual stimuli are clearly visible during saccades, and trigger a constriction of the eye's pupil. Participants viewed sinusoid gratings that changed polarity 150 times per second (every 6.67 ms). At this rate of flicker, the gratings were perceived as homogeneous surfaces while part...
متن کاملClassical conditioning of human 'evaluative' responses.
Human behaviour includes animportant component which may conveniently be called evaluative. Using postcard reproductions as stimulus materials. 10 volunteer subjects selected the two pictures most liked and the two most disliked. These were then used as UCSs with appropriate controls from the neutral category. The conditioning hypothesis-that a neutral stimulus followed by a positively or negat...
متن کاملMagnetic brain imaging of extinction processes in human classical conditioning.
By recording neuromagnetic events during aversive classical conditioning, we examined the extinction of a previously described conditioned response. Averaging over non-reinforced exposures to the conditioned stimulus revealed magnetic activity in the secondary somatosensory and insular cortices, appearing between 110 and 140 ms after the omitted unconditioned electric shock. We suggest this act...
متن کاملVariation of the intertrial interval in human classical conditioning
152 The eyeblink conditioning paradigm has been widely used as a model system to study associative learning (Disterhoft, Kwan, & Lo, 1977; R. F. Thompson et al., 1976). The neurobiological substrates underlying learning in this task have been extensively studied in animals (Disterhoft, L. T. Thompson, & Moyer, 1994; Moyer, Deyo, & Disterhoft, 1990; R. F. Thompson, 1991) and humans (Daum, Channo...
