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.

My purpose in this study was to examine the effect of verbal and visual feedback on an anticipation-timing task during a series of acquisition and retention trials. Participants were 48 high school students who were randomly assigned to visual-visual, visual-verbal, verbal-visual, and verbal-verbal conditions. I used a Bassin Anticipation Timer to measure coincidence-anticipation timing. Absolute error and variable error were calculated for 4 blocks of 10 trials in the acquisition phases, and 2 blocks of 10...
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...
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...
Effects of kind and amount of cognitive load and duration on prospective time estimation
Bıyık Sarı, Fatma; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2015)
The estimation of temporal intervals is influenced by characteristics of a secondary task carried out during those intervals. Different kinds of cognitive load (e.g., memory load, attentional demand) and different amounts of load (low, high) of the secondary tasks modulate time estimation. Increase in the amount of cognitive load decreases time estimation. According to the Attentional Gate Model this is because the more attention is allocated to the secondary task, the less attention is left for the primary...

Introduction: Interval timing requires cognitive resources such as attention, longterm memory, and working memory. Unfortunately, these functions deteriorate with aging. Changes in time perception are reported in healthy aging, in addition to several different neuropsychiatric disorders. Although age-related changes in time perception have been amply described in the literature, the actual underlying mechanisms remain controversial. Materials and Method: This study included a total of 33 young (mean age = 2...
