In two experiments, we explored the utility of using event-related brain potentials (ERPs) evoked during picture recognition to examine the cognitive and neural processes underlying primacy and recency effects. Each experiment consisted of 210 trials

The early processing of visual sexual stimuli shows signs of automaticity. Moreover, there is evidence for sex-specific patterns in cognitive and physiological responding to erotica. However, little is known about the time course of rapid pupillary r

The auditory P50/M50 ERP/event-related field is subject to sensory gating, with partial suppression of the amplitude of the second of two (S1 and S2) clicks presented 500 ms apart. Schizophrenia patients have less gating, although quantification meth

Growing evidence suggests that, contrary to expectation, high trait socially anxious (HTSA) and low trait socially anxious (LTSA) individuals show comparable autonomic reactivity during stressful speech tasks. To test the hypothesis that autonomic di

Emotion-provoking visual stimuli were presented to college undergraduates identified as anhedonic or normal, based on their scores on the Physical Anhedonia Scale (Chapman, Chapman, & Raulin, 1976). The affective stimuli (35 mm color slides) were cho

College-aged subjects performed 35 trials of an easy or difficult digit-recognition task. Half were told that a good performance would ensure a high chance of avoiding a blast of noise, and half were told that a good performance would ensure a low ch

Conventional operant biofeedback methods have not generally been successful in producing large-magnitude cardiac decelerations, whereas a Pavlovian approach using negative body tilt as an unconventional unconditional stimulus (US) has been reported t
