Valence-driven modulation of the startle reflex, that is larger eyeblinks during viewing of unpleasant pictures and inhibited blinks while viewing pleasant pictures, is well documented. The current study investigated, whether this motivational priming pattern also occurs during processing of unpleasant and pleasant words, and to what extent it is influenced by shallow vs deep encoding of verbal stimuli Emotional and neutral adjectives were presented for 5s, and the acoustically elicited startle eyeblink response was measured while subjects memorized the words by means of shallow or deep processing strategies Results showed blink potentiation to unpleasant and blink inhibition to pleasant adjectives in subjects using shallow encoding strategies In subjects using deep-encoding strategies, blinks were larger for pleasant than unpleasant or neutral adjectives In line with this, free recall of pleasant words was also better in subjects who engaged in deep processing. The results suggest that motivational priming holds as long as processing is perceptual However, during deep processing the startle reflex appears to represent a measure of "processing Interrupt". facilitating blinks to those stimuli that are more deeply encoded (C) 2010 Elsevier B.V All rights reserved
