Fearful body language is a salient signal alerting the observer to the presence of a potential threat in the surrounding environment.
Although detecting potential threats may trigger an immediate reduction of motor output in animals Although detecting potential threats may trigger an immediate reduction of motor output in animals i. Participants observed pictures of body postures and categorized them as happy, fearful or neutral while receiving TMS over the right or left motor cortex at msec after picture onset.
In three different sessions, we assessed corticospinal excitability, short intracortical inhibition SICI and intra Early changes in corticospinal excitability when seeing fearful body expressions.
Quick inhibition of approach tendencies in response to signals of potential threats is thought to promote survival. However, little is known about the effect of viewing fearful expressions on the early dynamics of the human motor system However, little is known about the effect of viewing fearful expressions on the early dynamics of the human motor system.
We used the high temporal resolution of single-pulse and paired-pulse transcranial magnetic stimulation TMS over the motor cortex to assess corticospinal excitability CSE and intracortical facilitation ICF during observation of happy, fearful and neutral body postures. To test motor circuits involved in approach tendencies, CSE and ICF were recorded from the first dorsal interosseous FDIa muscle involved in grasping, and the abductor pollicis brevis APBwhich served as a control.
Our study establishes an extremely rapid motor system reaction to observed fearful body expressions. This motor modulation involves corticospinal downstream projections but not cortical excitatory mechanisms, and appears to reflect an inhibition of hand grasping. Our results suggest a fast visuo-motor route that may rapidly inhibit inappropriate approaching actions.
Processing inflectional and derivational morphology: Electrophysiological evidence from Spanish. Gender activation in transparent and opaque words.
Determining the time course of lexical frequency and age of acquisition using ERP. The disfonoas goal of the present study was to dissociate the effects on reading of frequency, age of acquisition AoA and imageability using the evoked response potential paradigm.

Twenty participants read words from three experimental Twenty participants read words from three experimental conditions: High frequency words produced more positive mean amplitude than low frequency words in the ms post-stimulus onset time window and late AoA produced more negative amplitudes than early AoA in the ms window.
Imageability did not produce any effect in any time window tested. Brain electromagnetic tomography showed the most activated cortical areas for each category of stimuli. The lexical frequency of words seems to affect an early phase in the recognition process, perhaps at the level of the orthographic input lexicon, while AoA was observed at a later stage, indicating that this variable influence processing at a semantic level or at the links between semantics and phonology.

EEG permits the researcher to investigate the time course, and approximate location in the infantilees, of psycholinguistic variables. Tracking lexical and syntactic processes of verb morphology with ERP.
Counterfactual sentences activate embodied meaning: An action—sentence compatibility effect study. Recent evidence suggests that understanding factual action-related sentences involves embodied simulations. But, what happens with counterfactual sentences that describe hypothetical events in the past? This study demonstrates that even This study demonstrates that even in this case embodied simulations of actions take place.
Participants listened to factual or counterfactual sentences describing a transfer away from or towards them. After the transfer verb e. Finger motion was initially interfered with in cases involving a concurrent matching sentence e. The temporal course of this resonance differs slightly between factual and counterfactual sentences.
Canceling updating in the comprehension of counterfactuals embedded in narratives.
Reading times showed that readers were immediately sensitive to the special status of counterfactual information Experiment 1. In addition, probe-recognition latencies demonstrated that old information was more accessible in counterfactual than in factual stories, and new information was equally accessible in both kinds of stories Experiment 2. However, after reading additional clauses, new information became less accessible in counterfactual than in factual stories Experiment 3.
