Individual differences in the activation and control of affective race bias as assessed by startle eyeblink response and self-report.

The activation and control of affective race bias were measured using startle eyeblink responses (Study 1) and self-reports (Study 2) as White American participants viewed White and Black faces. Individual differences in levels of bias were predicted ...

Visual search strategies are indexed by event-related lateralizations of the EEG.

Two processes have been proposed for picking out information from a visual scene. A parallel process that detects salient features and a following serial process for higher order vision. However, this separation is still under dispute. The current study ...

Rule learning in a serial reaction time task: an fMRI study on patients with early Parkinsons disease.

In the present study, we investigated implicit rule learning in patients with Parkinsons disease (PD) and healthy participants. Functional magnetic resonance imaging (fMRI) and a variant of the serial reaction time task were employed to examine the ...

On the role of stimulus-response and stimulus-stimulus compatibility in the Stroop effect.

Stroop effects might be due to differences in stimulus-response compatibility (SRC) and/or to differences in stimulus-stimulus compatibility (SSC). Recent evidence for the role of SSC is inconclusive, because there were no controls for effects of SRC ...

Neural correlates of categories and concepts.

The ability to readily adapt to novel situations requires something beyond storing specific stimulus-response associations. Instead, many animals can detect basic characteristics of events and store them as generalized classes. Because these ...

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. ...

Effect of grammatical gender on visual word recognition: evidence from lexical decision and eye movement experiments.

Lexical decision times and eye movements were recorded to determine whether grammatical gender can influence the visual recognition of isolated French nouns. This issue was investigated by assessing the use of two types of regularities between a nouns ...

Countermanding saccades: evidence against independent processing of go and stop signals.

In a stop signal paradigm, subjects were instructed to make a saccade to a visual target appearing left or right of the fixation point. In 25% of the trials, an auditory stop signal was presented after a variable delay that required the subject to ...

The dynamical foundations of motion pattern formation: stability, selective adaptation, and perceptual continuity.

A dynamical model is used to show that global motion pattern formation for several different apparent motion stimuli can be embodied in the stable distribution of activation over a population of concurrently activated, directionally selective motion ...

The role of representational volatility in recognizing pre- and postchange objects.

Theories relating attention to change blindness (CB) imply that representations of objects in the focus of attention are stable and coherent. However, CB occurs for objects in the focus of attention. Here, we explore this apparent contradiction and the ...
