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. Three duration lengths (short-moderate-long) were used (15, 30 and 45 sec) that subjects had to reproduce. In Exp-1 (control experiment for Exp-2) subjects had to reproduce almost empty time intervals. Exp-2, which investigated the role of a secondary temporal task, revealed significantly decreased reproduced durations as compared to Exp-1 which is in line with our hypothesis. In Exp-3 (control experiment for Exp-4) subjects carried out a non-temporal/non-executive secondary task. Exp-4, in which a Simon task was used as a non-temporal executive secondary task, resulted in significantly decreased reproduced durations as compared to Exp-3 as well. Moreover, duration length effects were found for all experiments that included an attention consuming secondary tasks (Exp-2-3-4), i.e., longer durations were more underestimated than shorter ones in the presence of attention demanding tasks. We conclude that secondary temporal tasks and even more so executive non-temporal tasks can lead to decreased temporal duration judgements, thus affecting subjects’ time perception, in line with the Attentional Gate Model.

Prospective duration judgments: The role of temporality and executive demands of concurrent tasks
Duzcu, Haul; Hohenberger, Annette Edeltraud (Elsevier BV, 2014-03-01)
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 d...
Mood, Memory, and Motor Performance and the Severity of Tardive Dyskinesia
Gilleard, C. J.; Vaddadi, KS (SAGE Publications, 1986-12)
<jats:p> This study tested the hypothesis that the features of tardive dyskinesia were associated with motor slowing, memory impairment, and depressive apathy all of which are considered to characterize the so-called subcortical dementias. In a sample of 48 psychiatric patients all fulfilling research criteria for tardive dyskinesia and without other signs of organic illness age-independent correlations were observed between severity of orofacial dyskinesia and measures of memory, motor performance and mood...
Short-term consolidation of information for episodic memory
Özçelik, Erol; Tekman, Hasan Gürkan; Department of Cognitive Sciences (2008)
Several lines of evidence from rapid serial visual presentation, attentional blink, and dual-task interference phenomena propose that human beings have a significant limitation on the short-term consolidation process. Short-term consolidation is transferring early representations to more durable forms of memory. Although previous research has shown that masks presented after targets interrupt the consolidation process of information, there is not enough evidence for the role of attention in consolidation fo...
Investigation of Students’ Cognitive Processes in Computer Programming: A Cognitive Ethnography Study
Doğan, Sibel; Aslan, Orhan; Yıldırım, İbrahim Soner (2019-01-01)
The aim of the current study is to investigate how cognitive processes of students categorized as novice, semi-expert and expert differ in terms of creating pseudocode for a given programming task. To conduct this aim, cognitive ethnography research design was employed to reveal the cognitive process of the participants behind the specified task. In the study, three undergraduate students from a Computer Education and Instructional Technology (CEIT) department were included as participants. These students w...
An assessment of the status of the multiple realizability thesis in cognitive science
Baysan, Emin Umut; Temürcü, Ceyhan; Department of Cognitive Sciences (2011)
It has been argued that there are physically different ways of instantiating mental properties, the nature of which is the subject matter of cognitive science. This claim has been known as the Multiple Realizability Thesis (MRT). It has been suggested that the MRT shows that a reduction of mental properties to physical properties is impossible, as there cannot be one-to-one correspondences of mental properties to the properties of the brain. Moreover, it has been argued that the latter point shows that phys...
