Perception without awareness: further evidence from a Stroop priming task.

In the present research, we examined the influence of prime-target stimulus onset asynchrony (SOA) on Stroop-priming effects from masked words. Participants indicated the color of a central target, which was preceded by a 33-msec prime word followed ...

When action turns into words. Activation of motor-based knowledge during categorization of manipulable objects.

Functional imaging studies have demonstrated that processing of man-made objects activate the left ventral premotor cortex, which is known to be concerned with motor function. This has led to the suggestion that the comprehension of man-made objects may ...

Paradoxical interhemispheric summation in the split brain.

We measured simple reaction time (RT) to light flashes, presented either singly or in pairs, in two people who had undergone callosotomy, one person with agenesis of the corpus callosum, and 17 normal subjects. The three split-brained subjects RTs were ...

Saliency of peripheral targets in gaze-contingent multiresolutional displays.

Gaze-contingent multiresolutional displays (GCMRDs) have been proposed to solve the processing and bandwidth bottleneck in many single-user displays, by dynamically placing high-resolution in a window at the center of gaze, with lower resolution ...

Sex differences in face recognition--womens faces make the difference.

Sex differences favoring women have been found in face recognition tasks as well as in verbal episodic memory tasks. Womens higher face recognition performance was hypothesized to be related to either their higher verbal ability or to their superiority ...

Blink rate variability in patients with panic disorder: new trial using audiovisual stimulation.

Several lines of evidence have implicated central dopaminergic pathways in the modulation of spontaneous blink rate (BR). Furthermore, previous studies have indicated a relationship between spontaneous BR and anxiety and/or depression. However, to our ...

Visual field asymmetries and allocation of attention in visual scenes.

Single items such as objects, letters or words are often presented in the right or left visual field to examine hemispheric differences in cognitive processing. However, in everyday life, such items appear within a visual context or scene that affects ...

Serial attention mechanisms in visual search: a direct behavioral demonstration.

In visual search, inefficient performance of human observers is typically characterized by a steady increase in reaction time with the number of array elements-the so-called set-size effect. In general, set-size effects are taken to indicate that ...

Bisecting and behavior: lateral inattention predicts 8-week academic performance.

Converging evidence supports a left hemisphere role in defensive repression and sensation seeking. This led to the hypothesis that students with a relatively active left hemisphere would perform poorly during 8 weeks of a college class. The measure of ...

Divided and selective attention in panic disorder. A comparative study of patients with panic disorder, major depression and healthy controls.

OBJECTIVE: While depression is definitely a condition with diminished attentional functioning, there is little evidence as to whether attention is also disturbed in panic disorder. In the present study patients with panic disorder and with depression ...
