Learning-induced modulations of the stimulus-preceding negativity.
The neural basis of feedback expectation, which is crucial in learning theory, has only been minimally studied. Stimulus-preceding negativity (SPN), an ERP component that appears prior to the presentation of feedback, has been proposed as being related to feedback expectation. The present study showed, for the first time, amplitude modulations of the SPN component during learning acquisition in...
متن کاملStimulus-preceding negativity represents a conservative response tendency.
Humans tend to be conservative and typically will retain their initial decision even if an option to change is provided. We investigated whether the stimulus-preceding negativity (SPN), an event-related potential associated with the affective-motivational anticipation of feedback in gambling tasks, represents the strong response tendency to retain an initial decision. We compared SPNs in three ...
متن کاملStimulus-preceding negativity is modulated by action-outcome contingency.
We investigated the relationship between action-outcome contingency and stimulus-preceding negativity (SPN), a motivationally sensitive event-related potential. Neuroimaging studies have shown that insular cortex (a known source of the SPN) is more activated prior to rewards that are contingent on prior correct action than rewards that are given gratuitously. We compared two gambling tasks, one...
متن کاملError-negativity and positivity as they relate to other ERP indices of attentional control and stimulus processing.
We compared individual differences in the ERP associated with incorrect responses in a discrimination task with other ERP components associated with attentional control and stimulus discrimination (N2, P3, CNV). Trials with errors that are detected by the subject normally produce a negativity (N(E)) immediately following the response followed by a positivity (P(E)). The morphology of the N(E) a...
متن کاملStimulus-Preceding Negativity and heart rate changes in anticipation of affective pictures.
The aim of the present study was to investigate the affective modulation of the Stimulus-Preceding Negativity (SPN) and heart rate changes in anticipation of visual stimuli differing in emotional content. A S1-S2 task was employed with a word (S1) indicating the content of a subsequent emotional picture (S2). Both valence and arousal dimensions were manipulated by presenting positive and negati...
