ERP correlates of associative learning.
We examined changes of event-related potentials (ERPs) while participants learned stimulus-to-stimulus relations in an S1-S2 task. The design allowed for separating processes of associative learning from nonspecific effects. Participants had to respond to S2 by a left or right key-press dependent on S2 identity (letter W or M). Preparation for S2 could be improved by using the associative infor...
متن کاملAssociative Learning: Pavlovian Conditioning without Awareness
Can Pavlovian conditioning occur outside of awareness? Yes, according to a new study showing that, under a particular set of circumstances, visual stimuli can become associated with aversive outcomes without participants ever seeing the stimuli.
متن کاملElectrophysiological correlates of voice learning and recognition.
Listeners can recognize familiar human voices from variable utterances, suggesting the acquisition of speech-invariant voice representations during familiarization. However, the neurocognitive mechanisms mediating learning and recognition of voices from natural speech are currently unknown. Using electrophysiology, we investigated how representations are formed during intentional learning of in...
متن کاملFear conditioning with film clips: a complex associative learning paradigm.
BACKGROUND AND OBJECTIVES We argue that the stimuli used in traditional fear conditioning paradigms are too simple to model the learning and unlearning of complex fear memories. We therefore developed and tested an adapted fear conditioning paradigm, specifically designed for the study of complex associative memories. Second, we explored whether manipulating the meaning and complexity of the CS...
متن کاملWorrying Affects Associative Fear Learning: A Startle Fear Conditioning Study
A valuable experimental model for the pathogenesis of anxiety disorders is that they originate from a learned association between an intrinsically non-aversive event (Conditioned Stimulus, CS) and an anticipated disaster (Unconditioned Stimulus, UCS). Most anxiety disorders, however, do not evolve from a traumatic experience. Insights from neuroscience show that memory can be modified post-lear...
