Hemispheric asymmetries in rapid temporal processing at age 7 predict subsequent phonemic decoding 2 years later: A longitudinal event-related potential (ERP) study.

The asymmetric sampling in time hypothesis (AST) suggests that the left and right secondary auditory areas process auditory stimuli according to different sampling rates (Poeppel, 2003). We investigated whether asymmetries consistent with the AST are observable in children at age 7 and whether they become more pronounced at age 9. Data were collected from 50 children who attended a 2-day research program at age 7 and were followed up 2 years later.

Assessing hemispheric specialization for processing arithmetic skills in adults: A functional transcranial doppler ultrasonography (fTCD) study.

Background: A major model of the cerebral circuits that underpin arithmetic calculation is the triple-code model of numerical processing. This model proposes that the lateralization of mathematical operations is organized across three circuits: a left-hemispheric dominant verbal code; a bilateral magnitude representation of numbers and a bilateral Arabic number code.

New Method: This study simultaneously measured the blood flow of both middle cerebral arteries using functional transcranial Doppler ultrasonography to assess hemispheric specialization during the performance of both language and arithmetic tasks.

Error monitoring and empathy: Explorations within a neurophysiological context.

Past literature has proposed that empathy consists of two components: cognitive and affective empathy. Error monitoring mechanisms indexed by the error-related negativity (ERN) have been associated with empathy. Studies have found that a larger ERN is associated with higher levels of empathy.

Hemispheric asymmetries in auditory temporal integration: a study of event-related potentials.

According to the asymmetric sampling in time hypothesis, the left auditory cortex processes stimuli using a short temporal integration window (~25-50 ms), whereas the right auditory cortex processes stimuli using a long temporal integration window (~200 ms). We examined N1 and T-complex responses to the second tone of tone-pairs presented with inter-stimulus intervals (ISIs) of 50 and 200 ms. Twenty-seven undergraduate students were presented with stimuli binaurally whilst the EEG was recorded.

Dissociable components of cognitive control: an event-related potential (ERP) study of response inhibition and interference suppression.

Background: Cognitive control refers to the ability to selectively attend and respond to task-relevant events while resisting interference from distracting stimuli or prepotent automatic responses. The current study aimed to determine whether interference suppression and response inhibition are separable component processes of cognitive control.

Methodology/principal Findings: Fourteen young adults completed a hybrid Go/Nogo flanker task and continuous EEG data were recorded concurrently.
