Reverse effects of conditioning produced by two different unconditioned stimuli on thalamocortical transmission.
Actions of cerebellothalamocortical (CTC) networks on the musculature can be modified by associative conditioning in adult animals. During conditioning, electrical stimulation of a CTC network involved in forearm flexion movements results in either flexion or extension responses, depending on the somatosensory information given by the unconditioned stimulus (UCS). In the present work we attempt...
متن کاملElevated fear conditioning to socially relevant unconditioned stimuli in social anxiety disorder.
OBJECTIVE Though conditioned fear has long been acknowledged as an important etiologic mechanism in social anxiety disorder, past psychophysiological experiments have found no differences in general conditionability among social anxiety patients using generally aversive but socially nonspecific unconditioned stimuli (e.g., unpleasant odors and painful pressure). The authors applied a novel fear...
متن کاملSubliminal influence on preferences? A test of evaluative conditioning for brief visual conditioned stimuli using auditory unconditioned stimuli
In the field of evaluative conditioning (EC), two opposing theories-propositional single-process theory versus dual-process theory-are currently being discussed in the literature. The present set of experiments test a crucial prediction to adjudicate between these two theories: Dual-process theory postulates that evaluative conditioning can occur without awareness of the contingency between con...
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...
متن کاملDifferential effects of training intertrial interval on acquisition of trace and long-delay fear conditioning in rats.
Many factors govern conditioning effectiveness, including the intertrial interval (ITI) used during training. The present study systematically varied the training ITI during both trace and long-delay fear conditioning. Rats were trained using one of six different ITIs and subsequently tested for conditioning to the white noise conditioned stimulus (CS) and the training context. After trace cond...
