Enhanced salience and emotion recognition in Autism: a PET study.

OBJECTIVE: This study examined neural activation of facial stimuli in autism when the salience of emotional cues was increased by prosodic information. METHOD: Regional cerebral blood flow (rCBF) was measured while eight high-functioning men with autism ...

ADHD treatment and academic performance: a case series.

Most new cases of attention deficit-hyperactivity disorder (ADHD) are of the predominantly inattentive subtype. Research on the use of psychostimulants in these patients has shown a high rate of nonresponders. Although psychostimulants showed a ...

Assignment of reference to reflexives and pronouns in picture noun phrases: evidence from eye movements.

Most structural Binding Theories predict a complementary distribution between reflexives and pronouns in picture noun phrases containing possessors (e.g. "Kens picture of himself/him"). In two head-mounted eye-tracking experiments, listeners frequently ...

Recognition by top-down and bottom-up processing in cortex: the control of selective attention.

Visual recognition is achieved by a hierarchy of bidirectionally connected cortical areas. The entry of signals into higher areas involves the serial sampling of information within a movable window of attention. Here we explore how the cortex can move ...

Development of visual perception and attention, assessed by backward masking and application in children with epilepsy.

Visual masking assesses visual perception and attention; it occurs when a visual stimulus (mask) interferes with the perception of a stimulus that the participant is trying to identify (target). A backward masking study (target presented before mask) was ...

Fixation stability and saccadic latency in élite shooters.

This study tested the hypothesis that elementary visuo-motor functions involved in visual scanning, as measured by fixation and saccadic tasks, are better in a group of high-level clay target shooters (N=7) than in a control group (N=8). In the fixation ...

Effects of focus of attention depend on golfers skill.

In this study, we examined the influence of internal and external attention instructions on the performance of a pitch shot by golfers who were either highly skilled (mean handicap = 4) or low skilled (mean handicap = 26). Ten golfers in each skill group ...

Early behavior of optokinetic responses elicited by transparent motion stimuli during depth-based attention.

When two visual patterns moving in different directions are superimposed on the same depth plane (transparent motion stimulus), observers perceive transparent surfaces sliding over each other on different depth planes. Simultaneously, an optokinetic ...

Attention enhances feature integration.

Perceptual processing delays between attribute dimensions (e.g. color, form and motion) [Proceedings of the Royal Society of London Series B 264 (1997) 1407] have been attributed to temporal processing asynchronies resulting from functional segregation ...

Four-dot masking produces the attentional blink.

When two target stimuli (T1 and T2) are presented sequentially within half a second of each other, identification accuracy is often poor for T2. This phenomenon, known as attentional blink (AB), can be observed generally only if the stimulus terminating ...
