Innocuous cooling can produce nociceptive sensations that are inhibited during dynamic mechanical contact.

In a previous study of the heat grill illusion, sensations of burning and stinging were sometimes reported when the skin was cooled by as little as 2 degrees C. Informal tests subsequently indicated that these nociceptive sensations were experienced if ...

Inhibition of saccade initiation by preceding smooth pursuit.

In this study, we investigated the influence of smooth-pursuit eye movements on saccade initiation in response to a sudden jump of a continuously moving target. We replicated the finding by Tanaka et al. (1998) that saccadic eye movements in the ...

Visual-tactile spatial interaction in saccade generation.

Saccadic reaction times to visual targets tend to be faster when non-visual stimuli are presented in close temporal or spatial proximity even if subjects are instructed to ignore the accessory input. The effect tends to decrease with increasing spatial ...

Object motion perception is shaped by the motor control mechanism of ocular pursuit.

It is still a matter of debate whether the control of smooth pursuit eye movements involves an internal drive signal from object motion perception. We measured human target velocity and target position perceptions and compared them with the presumed ...

The influence of irrelevant stimulus changes on stimulus and response repetition effects.

In this study the influence of irrelevant stimulus changes from one trial to another in a serial reaction time task was investigated. Two experiments were performed in which subjects were required to respond to stimulus colour. Four colours were mapped ...

On the nature of insight solutions: evidence from skill differences in anagram solution.

According to the Gestalt psychologists, problem solutions that pop into mind suddenly with no awareness of the process by which they were generated are objectively as well as subjectively sudden. Thus, such pop-out solutions are qualitatively different ...

The effect of methylphenidate on three forms of response inhibition in boys with AD/HD.

The current study was aimed at (a) investigating the effect of three doses methylphenidate (MPH) and placebo on inhibition of a prepotent response, inhibition of an ongoing response, and interference control in Attention Deficit/Hyperactivity Disorder ...

A supramodal number representation in human intraparietal cortex.

The triple-code theory of numerical processing postulates an abstract-semantic "number sense." Neuropsychology points to intraparietal cortex as a potential substrate, but previous functional neuroimaging studies did not dissociate the representation of ...

The effects of single-dose fexofenadine, diphenhydramine, and placebo on cognitive performance in flight personnel.

BACKGROUND: Sedation and functional impairments are side effects associated with the use of first-generation antihistamines that preclude their use in aviation. Selected second-generation antihistamines do not have such side effects and have been ...

Is the emotional Stroop paradigm sensitive to malingering? A between-groups study with professional actors and actual trauma survivors.

Six professional actors, trained by psychologists and acting coaches to feign PTSD, were covertly enrolled into a treatment outcome study for PTSD with the aim of investigating malingering. During pretreatment assessment, individuals completed an ...
