Intermanual transfer in a simple motor task.

The present study examines the effects of a four-week training session in a pegboard task on uni- and bimanual performance. Of particular interest was whether practice transfer from the trained to the untrained hand takes place. Twenty-five consistently ...

Spectro-temporal processing in the envelope-frequency domain.

The frequency selectivity for amplitude modulation applied to tonal carriers and the role of beats between modulators in modulation masking were studied. Beats between the masker and signal modulation as well as intrinsic envelope fluctuations of ...

Virtual pitch integration for asynchronous harmonics.

This experiment examined the generation of virtual pitch for harmonically related tones that do not overlap in time. The interval between successive tones was systematically varied in order to gauge the integration period for virtual pitch. A pitch ...

Humans detect gaps in broadband noise according to effective gap duration without additional cues from abrupt envelope changes.

Previous studies of behavior and IC single units in the mouse support theoretical expectations that gaps with ramped trailing markers have reduced detectability compared to equivalent gaps with ramped leading markers. In experiment 1, detection ...

Within-ear and across-ear interference in a cocktail-party listening task.

Although many researchers have shown that listeners are able to selectively attend to a target speech signal when a masking talker is present in the same ear as the target speech or when a masking talker is present in a different ear than the target ...

Role of duration and interval in perception of force pulses.

Three experiments investigated the perceptual threshold for a pulsed force stimulation of the middle phalanx of the forefinger. The first experiment (N = 5) manipulated duration of the pulse, and the second (N = 6) manipulated the interval between ...

Effect of ethanol on psychomotor performance and on risk taking behaviour.

Ethanol may increase the willingness to take risks, but this issue remains controversial. We used a risk-taking paradigm in which volunteers answered a series of general knowledge questions with numerical answers and were asked to judge the length of a ...

Cold case homicides. Investigative interviews of child witnesses.

Nurses interviewing child witnesses in cold case homicide investigations face unique challenges arising from the passage of time. 2. Postevent influences must be evaluated carefully when examining childrens descriptions about remote events. 3. ...

Differential effect of a distractor on primary saccades and perceptual localization.

A distractor presented nearby the target of a goal-directed short latency saccade leads to spatial averaging, that is, the saccade lands between the target and the distractor. This so-called global effect is a characteristic feature of the spatial ...

A contemporary conceptual model of hypochondriasis.

Hypochondriasis (HC), which involves preoccupation with the fear of having a serious illness despite appropriate medical examination, is often encountered in medical settings. The most conspicuous feature of this disorder is seeking excessive reassurance ...
