Effects of joint action and nature of task setting on time perception

Usal, Kerem Alp
In this paper we study the effect of social condition on prospective time estimation: do we perceive temporal durations differently long when we perform a task (i) alone, (ii) with a collaborative, or (iii) with a competitive partner? Within the Attentional Gate Model (Block & Zakay, 2006), we argue that joint settings require more attentional resources than the single setting, leaving less resources for time estimation. Therefore, we expect that (i) temporal durations are more underestimated in the joint conditions than in the single condition, and (ii) within the joint conditions, temporal durations are more underestimated in the competitive than in the collaborative setting. N=90 participants were tested (30 in each condition). Participants performed a concurrent Simon task for three different durations (15, 30 and 45 seconds) which was followed by a time reproduction phase. In the single condition, participants performed all Simon as well as all time reproductions trials whereas in the joint conditions participants shared the Simon task and performed only half of the time reproductions. The number of time reproduction trials for participants in all conditions was the same. Participants were told that they would receive points for their correct responses in the Simon task. In the single condition they were told that they would be compared with others individually, in the cooperative condition with other dyads, and in the competitive condition with each other. In results, Helmert contrasts revealed a significant difference between the single and both dual conditions. Reproduction ratios in dual conditions were smaller than in the single condition. Also, the difference between cooperative and competitive conditions was significant. Reproduction ratios were smaller, indicating that durations were more underestimated in the competitive compared to the cooperative condition. The results provide first evidence that social condition affects time estimation. 


Effects of context on everyday conversations of Turkish university students
Hortacsu, N; Oral, A; Yasak, Y (Elsevier BV, 1996-12-01)
This study employed a diary method to investigate everyday conversations. Consistent with a dynamic view of partner context interaction, it was predicted that conversations occurring in different contexts would show variations with respect to topics and conversation partners. Turkish university students recorded durations, topics, and conversation partners of their conversations for seven consecutive days. Contexts, topics, and partners were categorized. Respondents were utilized as units of analyses. Analy...
Effect of individualized cognitive and postural task difficulty levels on postural control during dual task condition
Gursoy, Zeren G.; Yilmaz, Ugur; ÇELİK, HÜSEYİN; Arpinar-Avsar, Pinar; Kirazcı, Sadettin (2022-07-01)
© 2022 Elsevier B.V.Background: Previous dual task studies suggested that the difficulty of the concurrent cognitive and motor tasks may not be challenging to the same degree for each person. This study approaches this problem by setting individualized difficulty levels for tasks to examine the dual task interference. Research question: Do the features of postural sway depend on increased individualized difficulty levels of concurrent cognitive and postural activities? Methods: 20 young healthy participants...
Effect of tense, aspect and aspectual class on event knowledge activation: a study with Turkish adults
Yöntem, Şevki; Temürcü, Ceyhan; Department of Cognitive Sciences (2015)
In this study we aimed to investigate effects of tense, aspect and lexical aspect on the activation of event knowledge. To this end, we conducted a short stimulus onset asynchrony (SOA) experiment, in which participants encountered a one-word sentence as a prime and reacted to a locational target word via speech. We analyzed response times with respect to aspect, tense and relatedness between prime and target words. Participants’ memory spans, measured by a backward digit span task, were also included in th...
The Combined Effect of Light Touch and Cognitive Task Difficulty on Postural Control
çelik, tuğba; Kirazcı, Sadettin; Department of Physical Education and Sports (2021-10-12)
Studies investigating combined effects of light touch and cognitive task are limited and available results are inconsistent regarding effects of cognitive task on postural control. Therefore, this study investigated the combined effects of light touch and cognitive task difficulty on postural control. Participants performed cognitive task and light touch individually and simultaneously. Results indicated that both light touch and cognitive task improved postural sway individually. The cognitive task difficu...
Self-compassion and construal level theory: the role of self-compassion in decreasing the effect of social distance
Solmazer, Gaye; Özkan, Türker; Department of Psychology (2018)
Construal Level Theory (CLT) suggests that psychological distance determines the level of abstraction of mental representations used in cognition. It also suggests that this is important in determining how people evaluate, perceive and predict future, and behave. The aim of the present study was to investigate the role of trait and induced self-compassion in CLT. It was hypothesized that individuals who are dispositionally high in self-compassion or who are situationally induced to adopt self-compassion con...
