Manual asymmetries in the directional coding of reaching: further evidence for hemispatial effects and right hemisphere dominance for movement planning.

Directional coding of hand movements is of primary importance in the proactive control of goal-directed aiming. At the same time, manual reaction times are known to be asymmetric when reaching at lateralized targets. Generally, ipsilateral movements and ...

Intersensory redundancy facilitates discrimination of tempo in 3-month-old infants.

L. Bahrick and R. Lickliter (2000) proposed an intersensory redundancy hypothesis that states that information presented redundantly and in temporal synchrony across two or more sensory modalities selectively recruits infant attention and facilitates ...

Neuropsychological function in female victims of intimate partner violence with and without posttraumatic stress disorder.

BACKGROUND: Various aspects of neuropsychologic function have been reported to be abnormal in patients with posttraumatic stress disorder (PTSD); however, the majority of these data come from studies of seriously ill, treatment-seeking samples with ...

Long-term effects of covert face recognition.

Covert face recognition has previously been thought to produce only very short-lasting effects. In this study we demonstrate that manipulating subjects attentional load affects explicit, but not implicit memory for faces, and that implicit effects can ...

The temporal dynamics of the effects in occipital cortex of visual-spatial selective attention.

The temporal dynamics of the effects of lateralized visual selective attention within the lower visual field were studied with the combined application of event-related potentials (ERPs) and positron emission tomography (15O PET). Bilateral stimuli were ...

How does attention attenuate target-distractor interference in vision?. Evidence from magnetoencephalographic recordings.

This study used magnetoencephalographic and electroencephalographic recordings to investigate the neural mechanisms that underlie the attentional resolution of ambiguous feature coding in visual search. We addressed this issue by comparing neural ...

Attentional control of the processing of neural and emotional stimuli.

A typical scene contains many different objects that compete for neural representation due to the limited processing capacity of the visual system. At the neural level, competition among multiple stimuli is evidenced by the mutual suppression of their ...

Effects of practice on executive control investigated with fMRI.

Various models of executive control predict that practice should modulate the recruitment of executive brain mechanisms. To investigate this issue, we asked 15 participants to perform a cued global/local attention task while brain activity was recorded ...

Attentional effects in the visual pathways: a whole-brain PET study.

Attentional effects in the visual pathways were investigated by contrasting the distribution of regional cerebral blood flow (rCBF) measured by H(2)(15)O positron emission tomography (PET) during performance of a shape-matching task with the distribution ...

Enhancement of visual perception by crossmodal visuo-auditory interaction.

Neurophysiological studies have shown in animals that a sudden sound enhanced perceptual processing of subsequent visual stimuli. In the present study, we explored the possibility that such enhancement also exists in humans and can be explained through ...
