Microsaccades uncover the orientation of covert attention.

Fixational eye movements are subdivided into tremor, drift, and microsaccades. All three types of miniature eye movements generate small random displacements of the retinal image when viewing a stationary scene. Here we investigate the modulation of ...

Whose DAM account? Attentional learning explains Booth and Waxman.

Booth and Waxman (Cognition 84 (2002) B11) have recently shown that linguistic cues to animacy affect childrens novel name extensions. They argue that this demonstration contradicts two central tenets of our attentional learning account of object naming, ...

The effects of diazepam on sensory gating in healthy volunteers.

Sensory or P50 gating, as measured with the double click paradigm, reflects a slow inhibitory preattentional information process. It protects living organisms from being flooded by environmental stimuli. The effects of a single dose of diazepam (10 mg) ...

Inhibition of return for objects and locations in static displays.

When orienting attention, inhibition mechanisms prevent the return of attention to previously examined stimuli. This inhibition of the return of attention (IOR) has been shown to be associated additively with location- and object-based representations. ...

Inhibition of return and manual pointing movements.

To examine whether the motor inhibition of return (IOR) postulated by Taylor and Klein (1998, 2000) generalizes to manual guided movements or is restricted to saccadic responses, the following three experiments were conducted. The first experiment ...

Translation and competition among internal representations in a reverse Stroop effect.

In two experiments, the contributions of internal and external competition in a task known to produce a reverse Stroop effect were investigated. In this paradigm, the verbal meaning of an incongruent Stroop stimulus is identified by pointing to a patch ...

Between the frontier and the network: notes for a metapsychology of freedom.

The author examines the paradigm of the frontier and encounters the establishment of the paradigm of the network, a tendency that currently runs through diverse fields of thought. The network is not proposed as a globalising structure that would ...

Task switching mediates the attentional blink even without backward masking.

When two targets are presented in rapid succession, perception of the second target is impaired at short intertarget lags (100-700 msec). This attentional blink (AB) is thought to occur only when the second target is backward masked. To the contrary, we ...

Human prefrontal and sensory cortical activity during divided attention tasks.

In our natural environment, the ability to divide attention is essential since we attend simultaneously to a number of sensory modalities, e.g., to visual and auditory stimuli. In this study, functional magnetic resonance imaging (fMRI) was used to study ...

Neural coding of behavioral relevance in parietal cortex.

Flexible control of behavior requires the selective processing of task-relevant sensory information and the appropriate linkage of sensory input to action. A great deal of evidence suggests a central role for the parietal cortex in these functions. ...
