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 = 23.31 years) and 33 old (mean age = 67.63 years) individuals who performed a time bisection task with a range of 1.25-2.5 seconds. The experimental design was strictly controlled to minimize the effects of age-related declines in cognitive functions. An additional psychometric measurement related to the subjective passage of time was also assessed. Results: A Mann-Whitney U test was conducted with the bisection point, Weber ratio, and difference limen as the dependent variables. The young and old participants showed similar time bisection performances (p ≥ 0.05). However, the verbal expression of the subjects indicated that time generally passes faster for old individuals whereas old participants expected the next hour to pass slower for them than did their younger counterparts (p ≤ 0.05). Conclusion: It was demonstrated that the perception of time is preserved with aging in the supra-second range when cognitive demands are minimized by reducing task complexity.

The recently published ‘Research Agenda for General Practice/Family Medicine and Primary Health Care in Europe’ summarizes the evidence relating to the core competencies and characteristics of the Wonca Europe definition of GP/FM, and its implications for general practitioners/family doctors, researchers and policy makers. The European Journal of General Practice publishes a series of articles based on this document. In a first article, background, objectives, and methodology were discussed. In a second art...
Aging Slows Access to Temporal Information From Working Memory

To evaluate the impact of aging on controlled memory search operations, we investigated the retrieval of temporal order information from working memory (WM).
Age related changes in recognition memory for emotional stimuli
Kılıç, Aslı; Gökçay, Didem; Department of Cognitive Sciences (2007)
Recognition memory - a type of episodic memory in long term memory - is known in the literature to be affected by emotion, aging and the modality of the presented stimuli. The major aim of this study was to investigate whether emotional stimuli enhances recognition memory. Another goal was to observe whether modality and aging effects are present and differentiable in a non-Western subject sample. In literature, emotion studies were based on mainly two dimensions of emotions: valence and arousal. However, t...
Nested structure of time consciousness and its dependence on mental time travel competence and episodic memory
Dural Özer, Özge; Sol, Ayhan; Michaelian, Kourken; Department of Philosophy (2013)
The main objective of this master thesis is to clarify the nested structure in time consciousness, depending on mental time travel and episodic memory. Time consciousness, mental time travel and episodic memory are connected, and function depending on each other. Mental time travel ability enables us to imagine personal future events. Episodic memory allows us to travel mentally into both past and future. Similarity between remembering the past and imagining the future indicates that episodic memory system ...
Temporal and structural perception of rhythmic irregularities
Bostancı, Çağdaş; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2018)
Time perception studies often seek for a timing mechanism that can explain temporal judgments in a general way. In search of such a model, environmental, contextual and subjective factors affecting temporal judgments should be taken into account as well. The present study provides a critical evolution of existing timing models by comparing the interval processing and production strategies of musicians and non-musicians. The study contains 2 experiments: Experiment 1 is a perceptual comparison task and Exper...
