摘要

持续时间判断是认知生活的核心原则,然而,大量证据表明,精神分裂症和分裂型患者的时间感知受损。关于两者的相似病因的结论受到经验证据的限制,没有证据表明分裂型在时间生殖任务中的表现。第一次,一项时间复制任务研究了分裂型对视觉刺激的回顾范式和前瞻范式的影响。在实验1和实验2中,实验对象分别以回顾或前瞻性的方式再现了小猫视频的三种持续时间(15秒、30秒或45秒)中的一种,并播放了英国北安普顿内内河的视频。然后将这两个实验结合起来形成实验3。在回顾性范式中,受试者不被告知他们正在进行计时任务,而在前瞻性范式中,受试者知道他们正在进行计时任务。从这项研究中得出的关键发现是,高分裂型受试者在再现持续时间方面似乎有更高程度的准确性,这是由刺激环境介导的。这一发现意味着标量期望理论的起跳/累积成分可以用于进一步探索精神分裂症受试者的时间缺陷,并可能进一步暗示精神分裂症患者的时间缺陷是由注意力缺陷驱动的。

Ordinary people think merely of spending time, but schizotypy perceives time more accurately.

Duration judgement is a central component of cognitive functioning; however, a substantial body of evidence suggests that time perception is impaired in individuals with schizophrenia and schizotypy, respectively. Conclusions about the similar aetiology of both are constrained by empirical evidence with no evidence about the performance of schizotypy in the temporal estimation task. For the first time, a temporal estimation task examined the impact of schizotypy on both the retrospective and prospective paradigms for visual stimuli. The task involved subjects estimating one of three durations (15 s, 30 s, or 45 s) of a kitten video in either a retrospective or prospective paradigm in Experiment 1 and a video of the River Nene in Northampton, United Kingdom, in Experiment 2. Critical findings that emerged from this study are that high schizotypy subjects appear to have a greater degree of accuracy estimating durations, which is driven by the context of the stimulus. This finding implies that the pacemaker/accumulator component of scalar expectancy theory can be used to further explore timing deficits in schizophrenic subjects and might further imply that timing deficits in schizophrenia are driven by attentional deficits.

期刊介绍: Promoting the interests of scientific psychology and its researchers, QJEP, the journal of the Experimental Psychology Society, is a leading journal with a long-standing tradition of publishing cutting-edge research. Several articles have become classic papers in the fields of attention, perception, learning, memory, language, and reasoning. The journal publishes original articles on any topic within the field of experimental psychology (including comparative research). These include substantial experimental reports, review papers, rapid communications (reporting novel techniques or ground breaking results), comments (on articles previously published in QJEP or on issues of general interest to experimental psychologists), and book reviews. Experimental results are welcomed from all relevant techniques, including behavioural testing, brain imaging and computational modelling. QJEP offers a competitive publication time-scale. Accepted Rapid Communications have priority in the publication cycle and usually appear in print within three months. We aim to publish all accepted (but uncorrected) articles online within seven days. Our Latest Articles page offers immediate publication of articles upon reaching their final form. The journal offers an open access option called Open Select, enabling authors to meet funder requirements to make their article free to read online for all in perpetuity. Authors also benefit from a broad and diverse subscription base that delivers the journal contents to a world-wide readership. Together these features ensure that the journal offers authors the opportunity to raise the visibility of their work to a global audience.
