Resumo: | The present study analyses the modulatory effects of affective pictures in the early posterior negativity (EPN), the late positive potential (LPP) and the human startle response on both the peripheral (eye blink EMG) and central neurophysiological levels (Probe P3), during passive affective pictures viewing. The affective pictures categories were balanced in terms of valence (pleasant; unpleasant) and arousal (high; low). The data shows that EPN may be sensitive to specific stimulus characteristics (affective relevant pictures versus neutral pictures) associated with early stages of attentional processing. In later stages, the heightened attentional resource allocation aswell as themotivated significance of the affective stimuliwas found to elicit enhancedamplitudes of slow wave processes thought to be related to enhanced encoding, namely LPP,. Although pleasant low arousing pictureswere effective in engaging the resources involved in the slowwave processes, the highly arousing affective stimuli (pleasant and unpleasant) were found to produce the largest enhancement of the LPP, suggesting that high arousing stimulimay are associatedwith increasedmotivational significance. Additionally the response to high arousing stimulimay be suggestive of increasedmotivational attention, given the heightened attentional allocation, as expressed in the P3 probe, especially for the pleasant pictures. The hedonic valencemay then serve as amediator of the attentional inhibition to the affective priming, potentiating or inhibiting a shift towards defensive activation, as measured by the startle reflex. |
