Access to concrete word meanings in the cerebral hemispheres: facilitation and inhibition effects.

In 2002 Shibahara and Lucero-Wagoner, using a priming paradigm, reported a larger facilitation for concrete noun pairs in the right than left hemisphere when the stimulus onset asynchrony was 250 msec. Their related prime-target pairs were similar not ...

The effects of short-term training for spectrally mismatched noise-band speech.

The present study examined the effects of short-term perceptual training on normal-hearing listeners ability to adapt to spectrally altered speech patterns. Using noise-band vocoder processing, acoustic information was spectrally distorted by shifting ...

Semantic priming effect of metaphor constituent terms.

Camac and Glucksberg reported there was no priming effect between constituent terms of a metaphor and argued that there was no prior similarity or association between the constituents. However, their study had several limitations. An important one was ...

Quantity determination and the distance effect with letters, numbers, and shapes: a functional MR imaging study of number processing.

BACKGROUND AND PURPOSE: The ability to quantify, or to determine magnitude, is an important part of number processing, and the extent to which language and other cognitive abilities are involved with number processing is an area of interest. We compared ...

Modulation rate discrimination for unresolved components: temporal cues related to fine structure and envelope.

The present study investigated the hypothesis that the cues for modulation rate discrimination for unresolved spectral components differ as a function of the spectral region occupied by the stimuli. Specifically, it was hypothesized that when components ...

Optimization of experimental design in fMRI: a general framework using a genetic algorithm.

This article describes a method for selecting design parameters and a particular sequence of events in fMRI so as to maximize statistical power and psychological validity. Our approach uses a genetic algorithm (GA), a class of flexible search algorithms ...

Left and right occipital cortices differ in their response to spatial cueing.

We investigated cue and target-related laterality effects with event-related fMRI. Both left and right occipital areas responded maximally when both cue and target were presented in the contralateral visual hemifield (VF), and minimally when cue and ...

A region of mesial prefrontal cortex tracks monetarily rewarding outcomes: characterization with rapid event-related fMRI.

The function of the mesial prefrontal cortex (MPFC: including Brodman areas 10/12/32) remains an enigma. Current theories suggest a role in representing internal information, including emotional introspection, autonomic control, and a "default state" of ...

Perception of the low pitch of frequency-shifted complexes.

When all of the components in a harmonic complex tone are shifted in frequency by delta f, the pitch of the complex shifts roughly in proportion to delta f. For tones with a small number of components, the shift is usually somewhat larger than predicted ...

Promoting attentional health: importance to womens lives.

Promoting attentional health is an important opportunity to support and empower women to actively participate in their own health care and function effectively in multiple roles. Attention, the ability to focus or concentrate, is a necessary cognitive ...
