Distractor heterogeneity, attention, and color in visual search.

Experiments were designed to investigate the effects of set size and variation in the chromaticity of distractor stimuli on thresholds for detecting a target stimulus that differed from distractors only in chromaticity. Distractor chromaticities were ...

Temporal parameters and time course of perceptual latency priming.

Visual stimuli (primes) reduce the perceptual latency of a target appearing at the same location (perceptual latency priming, PLP). Three experiments assessed the time course of PLP by masked and, in Experiment 3, unmasked primes. Experiments 1 and 2 ...

Attention and emotion: an ERP analysis of facilitated emotional stimulus processing.

Recent event-related potential studies observed an early posterior negativity (EPN) reflecting facilitated processing of emotional images. The present study explored if the facilitated processing of emotional pictures is sustained while subjects perform ...

Social and cardiac responses of young children with autism.

The behavioral and heart rate responses of 22 children with autism and 22 children with other developmental disabilities were compared whilst they were watching videotapes of a baby either playing or crying. We expected both groups to show arousal as ...

Does excessive memory load attenuate activation in the prefrontal cortex? Load-dependent processing in single and dual tasks: functional magnetic resonance imaging study.

Functional magnetic resonance imaging was used to investigate the relationship between cortical activation and memory load in dual tasks. An n-back task at four levels of difficulty was used with auditory-verbal and visual-nonverbal material, performed ...

Neural correlates underlying mental calculation in abacus experts: a functional magnetic resonance imaging study.

Experts of abacus operation demonstrate extraordinary ability in mental calculation. There is psychological evidence that abacus experts utilize a mental image of an abacus to remember and manipulate large numbers in solving problems; however, the neural ...

Binocular rivalry and perceptual multi-stability.

When different images are presented to the two eyes, binocular rivalry can occur - that is, perceptual alternations between the two monocular images (bi-stability) or between more than two percepts comprised of complementary portions of the two images ...

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 ...

Researching the pathophysiology of pediatric bipolar disorder.

We suggest that the core feature of bipolar disorder (BPD) is marked state fluctuations. The pathophysiology of switches into depressed, irritable, and extreme positive valence states requires study, with the latter deserving particular focus because it ...

Attention as a characteristic of nonclinical dissociation: an event-related potential study.

Individual differences in dissociative style (which is generally considered a risk factor for dissociative pathology) were studied in a nonclinical sample. It was hypothesized that high-dissociative participants would show enhanced attentional abilities ...
