Investigation of the psychological length of a 1-s interval with a time production task.

Several studies using the production of 1-s intervals report instability in the results. This suggests that there is no clear representation of the value of 1 s in long-term memory. This instability may partly be explained by the specific methodological requirements of studies using 1-s production tasks. Typically, this task requires participants to produce 1-s intervals by either using two intermittent finger taps (one at the beginning and one at the end of the interval), or by continuously pressing a key for the duration of the second. The purpose of this study was to investigate the impact of two main factors on the production of 1-s intervals, namely the effects of kinesthetic cues (continuous press vs. two intermittent presses) and auditory cues (sound vs. no sound) during the production of each interval. Participants produced 30 1-s intervals under four conditions. The results showed significant effects of both kinesthetic and auditory factors on the produced intervals. The kinesthetic effects applied to both the accuracy (staying close to the 1-s target) and precision (minimizing intertrial variability), and the auditory effects were limited to accuracy. This study highlights that the expression of what is likely a representation of the psychological second in long-term memory is prone to much distortion. Explanations of this instability of the psychological second are explored, including the simultaneous involvement of circuits related to sub- (< 1 s) and supra-second (> 1 s) intervals and individual differences in the internal clock.

Time perspective predicts levels of anxiety and depression during the COVID-19 outbreak: A cross-cultural study.

The COVID-19 outbreak and governmental measures to keep the population safe had a great impact on many aspects of society, including well-being. Using data from N = 1281 participants from six countries (Argentina, France, Greece, Italy, Japan, and Turkey), we first explored differences in anxiety, depression (measured with the Hospital Anxiety and Depression Scale; HADS), and time perspectives (Zimbardo Time Perspective Inventory; ZTPI), between these countries during the first weeks of the pandemic. We observed that Turkish participants reported the highest levels of anxiety, and Japanese and Greek the lowest. For depression symptoms, the Japanese scored highest and Italians lowest. Next, for each country, we investigated how well the relatively time-stable personality traits of time perspectives, chronotype (reduced Morningness-Eveningness Questionnaire; rMEQ), and Big Five personality traits (short Big Five Inventory; BFI) predicted the levels of anxiety and depression (HADS). The regression analyses showed that negative attitudes towards the past predicted the levels of both anxiety and depression in most of the countries we analyzed. Additionally, in many countries, a Past Positive orientation negatively predicted depression whereas the Present Fatalistic subscale predicted anxiety and depression. The chronotype did not contribute additionally to the models. The Big Five traits (and particularly neuroticism) showed substantial incremental explanatory power for anxiety in some countries but did not consistently predict anxiety levels. For depression, the additional variance accounted for by including the BFI as predictors was rather small. Importantly, the ZTPI subscales were retained as significant predictors in the model still when the BFI and rMEQ were considered as potential predictors. Our results yield evidence that the ZTPI time perspectives are valuable predictors for anxiety and depression levels during the first period of the pandemic.

The Blursday database as a resource to study subjective temporalities during COVID-19.

The COVID-19 pandemic and associated lockdowns triggered worldwide changes in the daily routines of human experience. The Blursday database provides repeated measures of subjective time and related processes from participants in nine countries tested on 14 questionnaires and 15 behavioural tasks during the COVID-19 pandemic. A total of 2,840 participants completed at least one task, and 439 participants completed all tasks in the first session. The database and all data collection tools are accessible to researchers for studying the effects of social isolation on temporal information processing, time perspective, decision-making, sleep, metacognition, attention, memory, self-perception and mindfulness. Blursday includes quantitative statistics such as sleep patterns, personality traits, psychological well-being and lockdown indices. The database provides quantitative insights on the effects of lockdown (stringency and mobility) and subjective confinement on time perception (duration, passage of time and temporal distances). Perceived isolation affects time perception, and we report an inter-individual central tendency effect in retrospective duration estimation.

Pandemic, Quarantine, and Psychological Time.

This article addresses the feeling of strangeness about the perception of time that many people with ordinary lifestyles experienced during the quarantine imposed to fight the presence of COVID-19. It describes different aspects of psychological time affected by the interruption of a normal routine and suggests some cognitive mechanisms, attention, and memory that might have been at play, leading to perceive time as being more or less long. The article also describes the critical role of anxiety and temporal uncertainty and how they may affect the functioning of an internal clock and reminds the reader that there are individual differences in time-related aspects of the personality that contribute to the variety of impressions about duration experienced during the quarantine.
