Recovery from prior stimulation: masking of speech by interrupted noise for younger and older adults with normal hearing.

In a previous study [Dubno et al, J. Acoust. Soc. Am. 111, 2897-2907 (2002)], older subjects benefitted less than younger subjects from momentary improvements in signal-to-noise ratio when listening to speech in interrupted maskers. It has been ...

Modulation masking in cochlear implant listeners: envelope versus tonotopic components.

It is hypothesized that channel-interaction in cochlear implant listeners as measured in a modulation-masking experiment would be influenced by both the tonotopic overlap between masker and signal as well as an interaction between their envelopes. Two ...

Attention during looking and reaching as assessed by heart rate in 7(1/2)-month-old infants.

Attention mediates the acquisition and encoding of information about the world and is central to motor action. Heart rate deceleration and behavioral inhibition are sensitive indices of the attentional process, but it is unknown whether these indices are ...

Psychophysiological correlates in male to female transsexuals studied with a P300 investigation.

BACKGROUND: Transsexualism is thought to be related to cortical processes reflecting a complex mosaic of biological, psychological and social/cultural information. Since the P300 component of event-related potentials is considered as an index of ...

Impaired and enhanced attentional function in children with attention deficit/hyperactivity disorder.

BACKGROUND: The symptom domain of inattention in attention deficit/hyperactivity disorder (ADHD) suggests that there are neuropsychological fields of attention in which subjects with ADHD express deficits. However, studies using differentiated ...

Neuropsychological impairment in patients with major depressive disorder: the effects of feedback on task performance.

BACKGROUND: Recent evidence suggests that an abnormal response to performance feedback may contribute to the wide-ranging neuropsychological deficits typically associated with depressive illness. The present research sought to determine whether the ...

Activation of the visual cortex in motivated attention.

Functional activation (measured with fMRI) in occipital cortex was more extensive when participants view pictures strongly related to primary motive states (i.e., victims of violent death, viewer-directed threat, and erotica). This functional activity ...

Developmental change in the cross-modal Stroop effect.

E. M. Elliott, Cowan, and Valle-Inclan (1998) reported a cross-modal Stroop-like interference effect in adults when an auditory distractor (a color or noncolor word) occurred simultaneously with a color patch to be named. Response times were slower with ...

Visual search strategies are indexed by event-related lateralizations of the EEG.

Two processes have been proposed for picking out information from a visual scene. A parallel process that detects salient features and a following serial process for higher order vision. However, this separation is still under dispute. The current study ...

Known and novel noun extensions: attention at two levels of abstraction.

Two experiments tested the hypothesis that names direct attention at two levels of abstraction: Known names direct attention to the properties most relevant to the specific category; novel names direct attention to the shape, the property most generally ...
