This study sought to evaluate impaired response tendencies and modulation of automatic
processes in Parkinson's disease (PD), utilising a saccadic Simon task with stimulus …

In visual search, observers can successfully ignore temporally separated distractors that are
presented as a preview before onset of the search display. Previous behavioral studies have …

From the vast array of stimuli continually inundating our senses, only a very small portion is
selected for higher-order processing. This selection is influenced by voluntary and reflexive …

We used BOLD fMRI to study the differential effects of the direction of gaze on the visual and
the ocular motor systems. Fixation of a target straight ahead was compared to fixation of a …

Attending to a relevant item in a visual display is thought to require not only selective
attention to this item, but also active inhibition of surrounding distractor items. As a …

The definition of attention deficit hyperactivity disorder (ADHD) has undergone a major
transition from the time it was discovered to the present date. As previously discussed …

Attentional control involves the factors, or cognitive parameters, that determine which
environmental inputs receive attention and which do not. Cognitive studies of attentional …

OBJECTIVES:: Our study aimed at investigating the effect of repetitive recordings on
somatosensory evoked potentials (SEPs) related to spatial attention in a population of …

Ambiguous figures offer the chance to study endogenous changes in perception in the face
of constant stimulus input. We utilised the Necker cube with experimental instructions that …

Well-established behavioral paradigms were used to investigate the integrity of
interhemispheric communication among psychopathic offenders. We employed the …
