Inhibitory control following perinatal brain injury.

Evidence from developmental, lesion, and neuroimaging studies indicates that the prefrontal cortex plays a major role in executive abilities, including inhibitory control. Proficient executive performance, however, relies not only on the integrity of the ...

The role of axes of elongation and symmetry in rotated object naming.

Many theorists have postulated that axes of elongation and/or symmetry play an important role in the recognition of objects. In this paper, evidence is presented that mitigates this claim from independent assessments of the effects of axes of elongation ...

The effect of semantic distance in yes/no and go/no-go semantic categorization tasks.

The effect of semantic distance (Lund & Burgess, 1996) was examined in three semantic categorization experiments. Experiment 1, a yes/no task that required participants to make animal/nonanimal judgments by responding to both sets of stimuli (Forster & ...

Hemispheric asymmetry in the processing of emotional content in word meanings: the effect of current and past depression.

We examined hemispheric lateralization of emotion processing by comparing the performance of clinically depressed, previously depressed, and control individuals on a divided visual field task. Participants were asked to make affective valence judgments ...

Ipsilateral area 3b responses to median nerve somatosensory stimulation.

Magnetoencephalography investigation of the somatosensory evoked fields for median nerve stimulation detected ipsilateral area 3b responses in 18 hemispheres of 14 (1 normal subject and 13 patients with brain diseases) among 482 consecutive subjects. The ...

Compound fracture: the role of semantic transparency and morphological headedness.

This paper explores the role of semantic transparency in the representation and processing of English compounds. We focus on the question of whether semantic transparency is best viewed as a property of the entire multimorphemic string or as a property ...

Impaired distractor inhibition in patients with schizophrenia on a negative priming task.

BACKGROUND: Numerous studies have suggested, via the interpretation of negative priming effects, that subjects with schizophrenia are less able than controls to inhibit irrelevant distracting information. Further issues concerning impairment in ...

A method for quantifying reflex responses from intra-muscular and surface electromyogram.

Measuring human reflex responses from electromyogram (EMG) traces in an accurate, repeatable and reliable way with a high degree of specificity has traditionally been a difficult task. This paper describes a new method that can be used to quantify reflex ...

A role of the basal ganglia in movement: the effect of precues on discrete bi-directional movements in Parkinsons disease.

The effect of a precue on improving movement initiation (i.e., reaction time; RT) is well understood, whereas its influence on movement execution (i.e., movement time; MT) has rarely been examined. The current study investigated the influence of a ...

The "Flash-Lag" effect occurs in audition and cross-modally.

In 1958 MacKay showed that a rigidly moving object becomes visually fragmented when part of it is continuously visible but the rest is illuminated intermittently. For example, the glowing tip of a lit cigarette moving under stroboscopic illumination ...
