Fear Conditioning following Unilateral Temporal Lobectomy
The present study investigated fear-potentiated startle and autonomic learning in brain-lesioned patients in a classical fear-conditioning paradigm. Startle blink and skin conductance responses of 30 patients who underwent unilateral temporal lobectomy because of drugresistant epilepsy were compared with those of 32 healthy controls. As expected, temporal lobectomy patients showed a general imp...
متن کاملGeneralization of extinguished skin conductance responding in human fear conditioning.
In a human fear conditioning paradigm using the skin conductance response (SCR), participants were assigned to two groups. Following identical acquisition, group ABA (n = 16) was extinguished to a generalization stimulus (GS), whereas group AAB (n = 20) was extinguished to the conditioned stimulus (CS). At test, presenting the CS in group ABA yielded a strongly recovered SCR. Presenting the GS ...
متن کاملTemporal encoding in fear conditioning revealed through associative reflex facilitation.
Temporal encoding in Pavlovian fear conditioning was examined through conditional facilitation of the short-latency (Rl) component of the rat eyeblink reflex. Rats were fear-conditioned to a tone conditional stimulus (CS) with either a 3- or 9-s interstimulus interval (ISI) between CS onset and the onset of the grid-shock unconditional stimulus (US). Rl facilitation was tested over 2 days, in c...
متن کاملImpaired fear conditioning following unilateral temporal lobectomy in humans.
Classical fear conditioning was used in the present study as a model for investigating emotional learning and memory in human subjects with lesions to the medial temporal lobe. Animal studies have revealed a critical role for medial temporal lobe structures, particularly the amygdala, in simple and complex associative emotional responding. Whether these structures perform similar functions in h...
متن کاملFear Conditioning to Subliminal Fear Relevant and Non Fear Relevant Stimuli
A growing body of evidence suggests that conscious visual awareness is not a prerequisite for human fear learning. For instance, humans can learn to be fearful of subliminal fear relevant images--images depicting stimuli thought to have been fear relevant in our evolutionary context, such as snakes, spiders, and angry human faces. Such stimuli could have a privileged status in relation to manip...
