Complementary hemispheric specialization for word and accent detection.

When we hear a familiar word pronounced in a foreign accent, which parts of the brain identify the word and which identify the accent? Here we present converging evidence from PET blood flow, event-related scalp potentials, and behavioral responses ...

Attentional capture within and between objects.

The present study addressed the question whether attentional capture by abrupt onsets is affected by object-like properties of the stimulus field. Observers searched for a target circle at one of four ends of two solid rectangles. In the focused ...

Sound presentation rate is represented logarithmically in human cortex.

The encoding of temporal information is critical to auditory processing. Since the mismatch negativity component of the auditory event-related brain potential is thought to reflect properties of auditory sensory memory, we used it to examine the ...

Mental workload while driving: effects on visual search, discrimination, and decision making.

The effects of mental workload on visual search and decision making were studied in real traffic conditions with 12 participants who drove an instrumented car. Mental workload was manipulated by having participants perform several mental tasks while ...

What you believe versus what you think they believe: a neuroimaging study of conceptual perspective-taking.

Social communication requires shared representations as well as a cognitive flexibility for successful interactions between self and other. What neural mechanisms underlie the ability to distinguish between our own perspective vs. the perspective of ...

Illusory contours and specific regions of human extrastriate cortex: evidence from rTMS.

Functional magnetic resonance imaging studies showed that perception of illusory contours is associated with extrastriate cortex activation prevailing on the right side. 1 Hz repetitive transcranial magnetic stimulation (rTMS) is able to induce lasting ...

Measuring alcohol expectancies with the implicit association test.

Researchers have relied primarily on self-report questionnaires to measure alcohol expectancies. These questionnaires assess explicit expectancies about alcohol but donot provide any measure of the implicit processes that might also play an important ...

Interference effects from divided attention during retrieval in younger and older adults.

The authors examined how retrieval, under divided attention (DA) conditions, is affected by the type of material in a concurrent task, and whether aging produces larger interference effects on memory. Young and old adults studied a list of unrelated ...

Subitizing speed, subitizing range, counting speed, the Stroop effect, and aging: capacity differences and speed equivalence.

Thirty younger and 29 older adults were tested on reaction times for set size of a display of 1 to 9 digits. On half of the trials, the nominal value of the digits was equal to the size of the set displayed; on the other half, the value differed by 1 ...

Effects of illumination, viewing distance, and lighting color on perception time.

A laboratory study was carried out to investigate the effects of illumination, viewing distance, and lighting color on perception time with center high-mounted stop lamps comprised of light-emitting diodes. Analysis indicated that illumination, viewing ...
