Prospective duration judgments: The role of temporality and executive demands of concurrent tasks

Duzcu, Haul
Hohenberger, Annette Edeltraud
It is known that concurrent non-temporal tasks shorten reproduced temporal durations in prospective duration judgments. Two experiments were carried out, one comparing a concurrent temporal task to a minimally demanding concurrent task (Experiment 1) and one comparing an executive concurrent (Simon) task with a less demanding non-executive concurrent task (Experiment 2). An effect of the concurrent task type on temporal reproductions was found. Furthermore, a duration length effect was found, where longer durations were underestimated more than shorter durations. This effect tended to be stronger for the experiments that included a concurrent task that demanded high attention.


Prospective duration judgments: the role of attention and secondary tasks
Duzcu, Halil; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2011)
It is known that concurrent secondary tasks or attentionally salient stimuli shorten reproduced temporal durations. The main aim of this thesis is to use three types of secondary tasks to see their effects on duration judgments. The Attentional Gate Model (Block & Zakay, 2006) served as theoretical background for a series of 4 experiments. There were 2 baseline/control experiments for studying the effect of 2 different and novel secondary tasks which are temporal comparison and non-temporal executive tasks....
Implicit knowledge versus psychoacoustic similarity in priming of chords
Tekman, HG; Bharucha, JJ (American Psychological Association (APA), 1998-02-01)
A chord-priming paradigm was used to test predictions of a neural net model (MUSACT). The model makes a nonintuitive prediction: Following a prime chord, expectations for the target chord are based on psychoacoustic similarity al short stimulus onset asynchronies (SOAs) but on implicit knowledge of conventional relationships at longer SOAs. In a critical rest, 2 targets were selected for each prime. One was more psychoacoustically similar to the prime, and the other was more closely related on the basis of ...
Aging Slows Access to Temporal Information From Working Memory
Kılıç Özhan, Aslı; Oztekin, Ilke (Oxford University Press (OUP), 2017-11-01)
To evaluate the impact of aging on controlled memory search operations, we investigated the retrieval of temporal order information from working memory (WM).
The use of episodic and semantic memory systems in classroom context regarding time delay and college experience level
Elibol-Pekaslan, Nur; Şahin Acar, Başak (Wiley, 2018-11-01)
This study aimed to examine freshmen and senior college students' episodic and semantic memory use in classroom context regarding short and long time delays and college experience level. Data were collected in 2014 and 2017, right after students' final exams (T1) and 5 weeks later (T2). Students were given exemplar questions from their final exams and asked whether they remembered a specific learning episode (episodic memory), if they knew the information (semantic memory), or they guessed the answer while ...
Predicting applicant withdrawal: An expectancy theory perspective
Acikgoz, Yalcin; Sümer, Hayriye Canan (Informa UK Limited, 2018-01-01)
The purpose of this study was to examine the predictors of withdrawal from the job application process. To this end, this study used expectancy theory as its theoretical framework. Using data from 5,346 applicants to an entry-level military position in a large European military organization, results indicated that a positive change in job attraction, applicant emotional stability, and conscientiousness, and the amount of information and self-efficacy regarding selection procedures all had negative relations...
