Generators of visual evoked potentials for faces and eyes in the human brain as determined by dipole localization.

Human visual evoked potentials were recorded during presentation of photos of human and animal faces and various face features. Negative waves with approximate peak latencies of 165 msec (N170) were bilaterally recorded from the occipito-temporal ...

Aiding planning in air traffic control: an experimental investigation of the effects of perceptual information integration.

Prior research examined how controllers plan in their traditional environment and identified various information uncertainties as detriments to planning. A planning aid was designed to reduce this uncertainty by perceptually representing important ...

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 ...

Neural basis of mental scanning of a topographic representation built from a text.

Humans have the ability to build and to inspect an internal visual image of an environment built from a verbal description. We used positron emission tomography (PET) to investigate the brain areas engaged in the mental scanning of a map that subjects ...

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 ...

On the role of visual afferent information for the control of aiming movements toward targets of different sizes.

The authors investigated (a). whether the specificity of practice hypothesis is mediated by the importance of visual afferent information for the control of manual aiming movements and (b). how movement planning and online correction processes to the ...

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 ...

Identifying living and sentient kinds from dynamic information: the case of goal-directed versus aimless autonomous movement in conceptual change.

To reason competently about novel entities, people must discover whether the entity is alive and/or sentient. Exactly how people make this discovery is unknown, although past researchers have proposed that young children--unlike adults--rely chiefly on ...

Vection increases the magnitude and accuracy of visually evoked postural responses.

Movement of large visual scenes induces an illusion of self-motion (vection) and postural responses. We investigated if the conscious perception of self-motion influences the magnitude and directional accuracy of visually evoked postural responses. Five ...

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 ...
