“…Thus, the time frame of the present ERP effects (80-120 msec) might capture the initial moments of lexical access in these affective stimuli. Similar to our findings, those of Ortigue et al (2004) showed occipi-It is intriguing that the present ERP effect ascribed to arousal in negative words was localized in about the same brain region as was Kissler et al's (2007) localization of affective word processing. Their finding, however, was observed in a slightly later time frame.…”

“…There is evidence that emotional content influences ERPs to words during early time windows such as the P1 time window (80-120 ms; Bayer, Sommer, & Schacht, 2012;Bernat, Bunce, & Shevrin, 2001;Junghöfer, Bradley, Elbert, & Lang, 2001;Li, Zinbarg, & Paller, 2007;Scott, O'Donnell, Leuthold, & Sereno, 2009), and that involuntary attention allocation in the visual cortex is not limited to pictorial stimuli, but can occur for word stimuli which have only arbitrary relationships between their visual features and corresponding meaning (Bayer, et al, 2012;Ortigue et al, 2004;Rabovsky, Sommer, & Abdel Rahman, 2011). …”

Attentional biases to threat are considered central to anxiety disorders, however physiological evidence of their nature and time course is lacking. Event-related potentials (ERPs) characterized sensory and cognitive changes while 20 outpatients with panic disorder (PD), 20 with obsessive-compulsive disorder (OCD), and 20 healthy controls (HCs) responded to the color (emotional Stroop task) or meaning of threatening and neutral stimuli. ERPs indicated larger P1 amplitude and longer N1 latency in OCD, and shorter P1 latency in PD, to threatening (versus neutral) stimuli, across instructions to attend to, or ignore, threat content. Emotional Stroop interference correlated with phobic anxiety and was significant in PD. Participants with emotional Stroop interference had augmented P1 and P3 amplitudes to threat (versus neutral) stimuli when color-naming. The results suggest early attentional biases to threat in both disorders, with disorder-specific characteristics. ERPs supported preferential early attentional capture and cognitive elaboration hypotheses of emotional Stroop interference.

“…Among the ERP data on emotional words, there are also clues to a shift of activation from the LH to the RH (Bernat et al, 2001;Ortigue et al, 2004). One study that offers spatiotemporal evidence for such a shift was conducted by Ortigue et al; it employed a DVF technique along with a go/no-go lexical detection task.…”

A dual-process model is suggested for the processing of words with emotional meaning in the cerebral hemispheres. While the right hemisphere and valence hypotheses have long been used to explain the results of research on emotional stimulus processing, including nonverbal and verbal stimuli, data on emotional word processing are mostly inconsistent with both hypotheses. Three complementary lines of research data from behavioral, electrophysiological, and neuroimaging studies seem to suggest that both hemispheres have access to the meanings of emotional words, although their time course of activation may be different. The left hemisphere activates these words automatically early in processing, whereas the right hemisphere gains access to emotional words slowly when attention is recruited by the meaning of these words in a controlled manner. This processing dichotomy probably corroborates the complementary roles the two hemispheres play in data processing.
