Intentional and unintentional contributions to nonspecific preparation during reaction time foreperiods.
The nonspecific preparation that follows a warning stimulus (WS) to speed responding to an impending imperative stimulus (IS) is generally viewed as a strategic, intentional process. An alternative view holds that WS acts as a conditioned stimulus that unintentionally elicits a tendency to respond at the moment of IS presentation as a result of a process of trace conditioning. These views were ...
متن کاملIntentional and unintentional contributions to nonspecific preparation: electrophysiological evidence.
The authors hypothesized that there are distinct intentional and unintentional influences on nonspecific preparation for a future event. In 2 experiments, participants responded to an imperative stimulus (S-sub-2) that was presented equiprobably either 400 ms or 1,200 ms after the offset of a warning stimulus (S-sub-1). During the S-sub-1-S-sub-2 interval, the authors measured the contingent ne...
متن کاملReweighting sequential effects across different distributions of foreperiods: segregating elementary contributions to nonspecific preparation.
In the study of nonspecific preparation, the response time (RT) to an imperative stimulus is analyzed as a function of the foreperiod (FP), the interval between a warning stimulus and the imperative stimulus. When FP is varied within blocks of trials, a downward sloping FP-RT function is usually observed. The slope of this function depends on the distribution of FPs (the more negative the skewn...
متن کاملEpidemiological Pattern of Intentional and Unintentional Injuries Reported to Zahedan Forensic Medicine during 2008-2016
Aims: Intentional and unintentional injuries are known as a significant health problem, worldwide, and the leading causes of death, so that, about 5 million people die from violence and injuries annually, and thousands of injured, disabled, and disadvantaged people die for every person who dies. The aim of this study was to describe the epidemiological findings of intentional and unintentional ...
متن کاملDistraction by irrelevant sound during foreperiods selectively impairs temporal preparation.
When the interval between a warning signal (WS) and an imperative signal (IS), termed the foreperiod (FP), is variable across trials, reaction time (RT) to the IS typically decreases with increasing FP length. Here we examined the auditory filled-FP effect, which refers to a performance decrement after FPs filled with irrelevant auditory stimulation compared to FPs without additional stimulatio...
