Decision making requires evaluating alternatives that differ on a number of attributes. During this evaluation process, selection of options depends on the duration of the options, the duration of the expected delay for realizing the options, and the time available to reach a decision. This article reviews the relationship between time and decision making(More)
With two experiments it was examined whether one or two clocks operate the timing of two intervals presented simultaneously. The target interval always preceded the distracter interval, and was longer than it. Thus, the distracter was completely embedded within the target interval. The participants used the method of temporal production. The stimuli to be(More)
Three experiments investigated temporal generalization performance under conditions in which participants were instructed to make their decisions as quickly as possible (speed), or were allowed to take their time (accuracy). A previous study (Klapproth & Müller, 2008) had shown that under speeded conditions people were more likely to confuse durations(More)
In two experiments, participants performed a temporal generalization task in which they were asked to decide whether or not the durations of comparison stimuli were different from those of standard stimuli (750 ms, 1,000 ms, or 1,250 ms). One half of the participants was instructed to respond as quickly as possible, while the other half received no(More)
52 women and 20 men (M age = 25.3 yr., SD = 4.1) reproduced one of three durations (15, 30, and 45 sec.) of a uniform visual stimulus in either a prospective or a retrospective estimation paradigm. In contrast to the prospective conditions, the participants in the retrospective conditions did not know that time estimation would be required subsequently.(More)
A study containing four experiments provided evidence in favour of assimilation effects in retrospective duration judgments due to temporal expectations. In this study, the participants did not know in advance that they would have to reproduce the duration of a target interval. Temporal expectations were induced prior to the target interval by the repeated(More)
In the present study, individuals with substance use disorders (n=30) and non-addicted controls (n=30) were presented with a delay-discounting task with time being described either as dates or as temporal intervals. Three main results were obtained. First, in both groups reward size had a large impact on discounting future rewards, with discount rates(More)
