Visual selective behavior can be triggered by a feed-forward process.

The ventral visual pathway implements object recognition and categorization in a hierarchy of processing areas with neuronal selectivities of increasing complexity. The presence of massive feedback connections within this hierarchy raises the possibility ...

Differential brain activation patterns during perception of voice and tone onset time series: a MEG study.

Evoked magnetic fields were recorded from 18 adult volunteers using magnetoencephalography (MEG) during perception of speech stimuli (the endpoints of a voice onset time (VOT) series ranging from /ga/ to /ka/), analogous nonspeech stimuli (the endpoints ...

Stroop dilution but not word-processing dilution: evidence for attention capture.

Stroop dilution refers to the observation that the impact of a color word on the naming of a color bar is reduced if another word-like object is displayed simultaneously. Recently, Brown, Roos-Gilbert, and Carr (1995) concluded that Stroop dilution is ...

When the target becomes the mask: using apparent motion to isolate the object-level component of object substitution masking.

J. T. Enns and V. Di Lollo (1997) discovered a new form of visual masking that they labeled object substitution masking (OSM). OSM occurs when 4 dots, presented around a target, trail in the display after target offset. The present study showed that the ...

Premotor cortex in observing erroneous action: an fMRI study.

The lateral premotor cortex (PMC) is involved during action observation in monkeys and humans, reflecting a matching process between observed actions and their corresponding motor schemata. In the present study, functional magnetic resonance imaging ...

Shifts of attention in light and in darkness: an ERP study of supramodal attentional control and crossmodal links in spatial attention.

Crossmodal links in spatial attention, uncovered by recent behavioural and electrophysiological studies, have been interpreted as evidence for supramodal processes controlling shifts of attention. However, previous experiments have usually been conducted ...

Visual-tactile spatial interaction in saccade generation.

Saccadic reaction times to visual targets tend to be faster when non-visual stimuli are presented in close temporal or spatial proximity even if subjects are instructed to ignore the accessory input. The effect tends to decrease with increasing spatial ...

Differential effects of developmental cerebellar abnormality on cognitive and motor functions in the cerebellum: an fMRI study of autism.

OBJECTIVE: Recent years have seen a revolution in views regarding cerebellar function. New findings suggest that the cerebellum plays a role in multiple functional domains: cognitive, affective, and sensory as well as motor. These findings imply that ...

Implicit memory bias and trait anxiety: a psychophysiological analysis.

The effect of threatening words and anxiety upon implicit memory performance was investigated. It was predicted that anxious individuals would show a bias to threat-related material. In addition, psychophysiological measures were obtained to assess the ...

Abrupt onsets and gaze direction cues trigger independent reflexive attentional effects.

The present study investigated whether the direction of visual signals is influenced independently by two automatic visual orienting phenomena: orienting to a gazed-at location and inhibition of return (IOR) to the location of an abrupt onset. A ...
