“…First, a comparison of semantic and affective catego rization speeds for the same stimuli shows that affective discrim ination is in fact slower than semantic categorization (Nummen maa, Hyona, & Calvo, 2010). Second, the earliest event-related potentials (ERPs) that are consistently modulated by affective stimulus content occur around 170 ms for emotional facial expres sions (e.g., Ashley, Vuilleumier, & Swick, 2004;Batty & Taylor, 2003;Blau et al, 2007;Campanella et al, 2002;Eger et al, 2003;Krombholz, Schaefer, & Boucsein, 2007), and around 200-300 for arousal for complex emotional scenes (see review in Olofsson, Nordin, Sequeira, & Polich. 2008).…”

Studies using backward masked emotional stimuli suggest that affective processing may occur outside visual awareness and imply primacy of affective over semantic processing, yet these experiments have not strictly controlled for the participants' awareness of the stimuli. Here we directly compared the primacy of affective versus semantic categorization of biologically relevant stimuli in 5 experiments (n = 178) using explicit (semantic and affective discrimination; Experiments 1-3) and implicit (semantic and affective priming; Experiments 4-5) measures. The same stimuli were used in semantic and affective tasks. Visual awareness was manipulated by varying exposure duration of the masked stimuli, and subjective level of stimulus awareness was measured after each trial using a 4-point perceptual awareness scale. When participants reported no awareness of the stimuli, semantic and affective categorization were at chance level and priming scores did not differ from zero. When participants were even partially aware of the stimuli, (a) both semantic and affective categorization could be performed above chance level with equal accuracy, (b) semantic categorization was faster than affective categorization, and (c) both semantic and affective priming were observed. Affective categorization speed was linearly dependent on semantic categorization speed, suggesting dependence of affective processing on semantic recognition. Manipulations of affective and semantic categorization tasks revealed a hierarchy of categorization operations beginning with basic-level semantic categorization and ending with superordinate level affective categorization. We conclude that both implicit and explicit affective and semantic categorization is dependent on visual awareness, and that affective recognition follows semantic categorization.

“…The criteria for identifying each ERP peak and latency were established based on the mean global field potential (MGFP) of all participants (Lee et al, 2010;Jung et al, 2012) and based on previous similar studies (Streit et al, 1999;Onitsuka et al, 2006;Blau et al, 2007;Turetsky et al, 2007;Wynn et al, 2008b): the P100 component had the maximum positive potential from 50 to 150 ms after the stimulus onset at electrodes PO7 and PO8; N170 had the largest negative peak in ERP amplitude from 120 to 220 ms at P7/PO7 and P8/PO8; N250 had the biggest negative potential in F1/FC1/FC3 and F2/FC2/FC4 at a latency of 150 to 350 ms; and the P300 component had the largest positive peak at electrodes F1/FC1 and F2/FC2 from 300 to 450 ms post stimulus.…”

“…Of particular interest for the present study are the N170 component, and the later P2 component. The N170 ERP component is reliably observed following face stimuli (Bentin et al, 1996) and has been seen to be modulated by emotional content of the face (Batty & Taylor, 2003;Blau et al, 2007), such that a greater N170 is observed for fearful faces. Other studies have shown that later components are modulated by both emotion (Eimer & Holmes, 2002) and facial recognition (Gosling & Eimer, 2011).…”

Please cite this article as: Hughes, Gethin, ERP and behavioral evidence of increased sensory attenuation for fear related action outcomes.Biological Psychology http://dx. Highlights  Increased sensory attenuation for fearful compared to neutral faces.  Neurophysiological attenuation for predicted fearful faces only.  Enhanced subjective fear ratings for congruent fearful faces. Abstract Voluntary action selection entails the representation of the expected consequences of the action. Previous evidence suggests that accurate action-effect prediction modulates both ERP and behavioural markers of sensory processing-a phenomenon know as sensory attenuation. This may play an important role in monitoring the success or failure of our actions, or attributing agency. Nonetheless, the vast majority of studies in this domain focus on simplistic visual and auditory stimuli. Given that we rarely perform voluntary actions with the aim of generating such stimuli in social contexts, this provides little indication of the extent to which sensory attenuation operates in everyday behavior. The present study investigated ERP and behavioral measures of sensory attenuation for fearful and neutral facial expressions. Participants were trained to associate one voluntary action with the presentation of a fearful face, and another action with a neutral face. We measured both ERP responses and behavioural ratings following presentation of faces whose emotional content was either consistent or inconsistent with the action prediction. We observed significant modulation for fearful outcomes only, suggesting that sensory attenuation is heightened to stimuli of high social relevance. The N170 response was significantly attenuated for congruent fearful faces, but not for congruent neutral faces (in comparison to incongruent faces). Similarly, behavioral ratings were modulated only for fearful faces but not neutral faces. This provides new insight into how social and affective outcomes modulate sensory attenuation and may have implications for implicit sense of agency for socially relevant stimuli.
