Comparing event-related and epoch analysis in blocked design fMRI.

In this study we demonstrate that, even in blocked design fMRI, an event-related analysis may provide a more accurate model of the hemodynamic responses than an epoch-related analysis. This is because the temporal shape of the predicted response differs ...

Working-memory capacity and the control of attention: the contributions of goal neglect, response competition, and task set to Stroop interference.

Individual differences in working-memory (WM) capacity predicted performance on the Stroop task in 5 experiments, indicating the importance of executive control and goal maintenance to selective attention. When the Stroop task encouraged goal neglect by ...

Preattentive auditory context effects.

The effects of auditory context on the preattentive and perceptual organization of tone sequences were investigated. Two sets of experiments were conducted in which the pitch of contextual tones was varied, bringing about two different contextual ...

Working memory controls involuntary attention switching: evidence from an auditory distraction paradigm.

One function of working memory is to protect current mental processes against interference. In contrast, to be able to react flexibly on unpredictable environmental changes working memory should not totally be encapsulated from processing task unrelated ...

Personality systems interactions theory and the theory of planned behaviour: evidence that self-regulatory volitional components enhance enactment of studying behaviour.

The role of volitional components specified by personality systems interactions theory in enhancing behavioural prediction was examined in a longitudinal investigation of students studying. Participants completed measures specified by the theory of ...

Neural basis of the non-attentional processing of briefly presented words.

The neural basis of the automatic activation of words was investigated in an fMRI study. In the study, words were presented briefly (51 or 151 msec) followed by a mask. To prevent attentional processing, subjects attended to the masks and not the words, ...

Does luminance-contrast contribute to a saliency map for overt visual attention?

In natural environments, humans select a subset of visual stimuli by directing their gaze to locations attended. In previous studies it has been found that at fixation points luminance-contrast is higher than average. This led to the hypothesis that ...

Novelty responses and differential effects of order in the amygdala, substantia innominata, and inferior temporal cortex.

Recent studies of amygdala function have focused on examining responses to emotionally valenced versus neutral stimuli. However, electrophysiologic and neuroimaging studies also suggest that novel neutral faces activate the amygdala, though few ...

Visual recognition of biological motion is impaired in children with autism.

Autistic children and typically developing control children were tested on two visual tasks, one involving grouping of small line elements into a global figure and the other involving perception of human activity portrayed in point-light animations. ...

The posterior cingulate and medial prefrontal cortex mediate the anticipatory allocation of spatial attention.

The purpose of this study was to identify brain regions underlying internally generated anticipatory biases toward locations where significant events are expected to occur. Subjects fixated centrally and responded to peripheral targets preceded by a ...
