“…The N400 effects differed in magnitude although the (button press) responses were the same for both error types, and in Experiment 1, N400 effects were also obtained in the absence of a motor response. Furthermore, the obtained ERP effects are not comparable to known ERP components of motor responses regarding their polarity, magnitude and component shape (Kornhuber, and Deecke, 1965;Walter, Cooper, Aldridge, McCallum, and Winter, 1964).…”

Event-related brain potentials during the monitoring of speech errors

a b s t r a c t a r t i c l e i n f oWhen we perceive speech, our goal is to extract the meaning of the verbal message which includes semantic processing. However, how deeply do we process speech in different situations? In two experiments, native Dutch participants heard spoken sentences describing simultaneously presented pictures. Sentences either correctly described the pictures or contained an anomalous final word (i.e. a semantically or phonologically incongruent word). In the first experiment, spoken sentences were task-irrelevant and both anomalous conditions elicited similar centro-parietal N400s that were larger in amplitude than the N400 for the correct condition. In the second experiment, we ensured that participants processed the same stimuli semantically. In an early time window, we found similar phonological mismatch negativities for both anomalous conditions compared to the correct condition. These negativities were followed by an N400 that was larger for semantic than phonological errors. Together, these data suggest that we process speech semantically, even if the speech is task-irrelevant. Once listeners allocate more cognitive resources to the processing of speech, we suggest that they make predictions for upcoming words, presumably by means of the production system and an internal monitoring loop, to facilitate lexical processing of the perceived speech.

“…The Contingent Negative Variation (CNV) was shown to build up prior to the onset of a stimulus to which participants were required to respond (Walter et al, 1964). It is fitting that this anticipatory effect was the first of the ERP components indexing cognitive processes discovered in the modern era (see also Kornhuber & Deecke, 1965). This era is marked by the advent of averaging together potentials time-locked to an observable event and recorded on multiple trials to extract the small amplitude voltage fluctuations common to each trial from the much larger amplitude EEG ‘noise’ in which they are embedded (Dawson, 1954; Donchin, 1969; Donchin & Heffley, 1975; Galambos & Sheatz, 1962).…”

Due to the precise temporal resolution of electrophysiological recordings, the event-related potential (ERP) technique has proven particularly valuable for testing theories of perception and attention. Here, I provide a brief tutorial of the ERP technique for consumers of such research and those considering the use of human electrophysiology in their own work. My discussion begins with the basics regarding what brain activity ERPs measure and why they are well suited to reveal critical aspects of perceptual processing, attentional selection, and cognition that are unobservable with behavioral methods alone. I then review a number of important methodological issues and often forgotten facts that should be considered when evaluating or planning ERP experiments.

“…According to this view, the preSMA is activated by the anticipation of and the attention to the forthcoming stimuli within the monitored stimulus sequence. This function has already been implied by studies on the so-called readiness potential (Kornhuber and Deecke, 1966;Yazawa et al, 2000). In particular, it is suggested that the preSMA underlies sensory information processing in view of a potential decision making or motor selection for the action toward this sensory information (Ikeda et al, 1999).…”

A Blueprint for Target Motion: fMRI Reveals Perceived Sequential Complexity to Modulate Premotor Cortex

The execution of movements that are guided by an increasingly complex target motion is known to draw on premotor cortices. Whole-brain functional magnetic resonance imaging was used to investigate whether, in the absence of any movement, attending to and predicting increasingly complex target motion also rely on premotor cortices. Complexity was varied as a function of number of sequential elements and amount of dynamic sequential trend in a pulsing target motion. As a result, serial prediction caused activations in premotor and parietal cortices, particularly within the right hemisphere. Parametric analyses revealed that the right ventrolateral premotor cortex and the right anterior intraparietal sulcus were the only areas that, in addition, covaried positively with both behavioral and physical measures of sequential complexity. Further areas that covaried positively with increasing task difficulty reflected influences of both number and trend manipulation. In particular, increasing element number drew on dorsal premotor and corresponding posterior intraparietal regions, whereas increasing trend drew on the visual motion area and area V4. The present findings demonstrate that premotor involvement directly reflects perceptual complexity in attended and predicted target motion. It is suggested that when we try to predict how a target will move, the motor system generates a "blueprint" of the observed motion that allows potential sensorimotor integration. In the absence of any motor requirement, this blueprint appears to be not a byproduct of motor planning, but rather the basis for target motion prediction.
