采用工作记忆和时间判断的双任务范式,探讨了言语工作记忆的保持过程对时间知觉的影响。研究中操作记忆负荷和任务之间的时间间隔(ISI:记忆刺激消失到时间判断任务开始之间的时间间隔)。结果发现,记忆负荷越大,知觉到的时间越短,韦伯比例越低,反应时间越长;ISI越短,知觉到的时间变短,反应时间越长,这表明知觉时间和反应决策是一致的,不存在累加时间和反应判断之间的trade-off。但是记忆负荷和ISI的交互作用不显著。结果表明记忆负荷和ISI以不同的方式影响时间判断,言语工作记忆的保持和时间加工共享工作记忆资源。 相似文献

In this diary study, we extended knowledge on the role of employees’ stress mindset in the anticipatory phase of the stress process. We examined how workload anticipation is related to approach-coping efforts throughout the workday and how employees’ stress mindset moderates this relationship. Moreover, we investigated how approach-coping efforts are related to vigour and task performance at the end of the workday. Finally, we proposed conditional indirect effects of workload anticipation on vigour and task performance that are moderated by employees’ stress mindset. We conducted a daily diary study over five workdays with 171 employees. Results of multilevel path analysis showed that employees with a more positive stress mindset made more approach-coping efforts when anticipating high workload. Approach-coping efforts were positively related to vigour and task performance. For employees with a more positive stress mindset, workload anticipation had a positive conditional indirect effect on vigour and task performance. Our results suggest that employees react differently to workload anticipation depending on their stress mindset. Moreover, approach-coping efforts may be a cognitive-behavioural mechanism that explains how workload relates to vigour and task performance for employees with a more positive stress mindset. 相似文献

Priority decisions concerning maintenance or reconstruction of roads are made with the aim of road improvements with as little traffic disturbance and time loss as possible. However, it cannot be avoided that speed will be reduced and travel time increased during the time of construction. The present study shows how intuitive judgments of travel time losses are biased in a way similar to the times saving bias (Svenson, 2008), but not perfectly corresponding to that bias. This means that when speed is decreased from a slow speed <50 km/h, the time loss is underestimated and when speed is decreased from a high speed >80 km/h it is overestimated. Also, drivers, politicians and policy makers who do not make exact calculations are likely victims of the time loss bias. The time loss bias was weakened but not eliminated by a debiasing instruction including mathematical computations of travel times. When driving speed restrictions are implemented, in particular on fast motorways, it is necessary to consider and counteract the time loss bias and inform the public. This can be done, for example, in communications about travel time facts, by information in driver training and by mounting temporary road signs informing about the average travel time prolongation due to a road work. 相似文献

本研究采用复制时距和数字加工双任务,探讨数字大小影响时距知觉的机制。实验首先呈现不同时距的圆点,然后让被试按键复制圆点呈现的时距,与此同时,对屏幕上出现的数字进行命名(实验1)、奇偶数判断(实验2)、大小判断(实验3)。实验结果发现对数字进行奇偶数判断时,数字大小对时距知觉没有影响;进行数字命名和大小判断任务时,数字大小对时距知觉都产生了影响,并且时距不同,数字大小对时距知觉的影响也不同。该结果表明时距知觉的数字效应与数字加工任务和时距长短有关,呈现出动态变化的过程。 相似文献

采用线索Go/Nogo任务,运用ERPs技术考察了老年人和青年人在自动化情绪调节上的差异。ERPs结果显示:⑴愉快面孔比中性面孔诱发的Go-N2波幅较小,潜伏期较短;Nogo-P3波幅较大,潜伏期较短,表明情绪面孔比中性面孔更能吸引注意;⑵在愉快面孔上,老年组比青年组的Go/Nogo-P3波幅大、潜伏期差异不显著;在悲伤面孔上,老年组比青年组的Go/Nogo-P3波幅大,Nogo-P3潜伏期长,说明老年组比青年组更加抑制对悲伤面孔的反应,老年人在自动化情绪调节中表现出一定程度的积极效应。 相似文献

In recent decades, many computational techniques have been developed to analyse the contextual usage of words in large language corpora. The present study examined whether the co-occurrence frequency obtained from large language corpora might boost purely semantic priming effects. Two experiments were conducted: one with conscious semantic priming, the other with subliminal semantic priming. Both experiments contrasted three semantic priming contexts: an unrelated priming context and two related priming contexts with word pairs that are semantically related and that co-occur either frequently or infrequently. In the conscious priming presentation (166-ms stimulus-onset asynchrony, SOA), a semantic priming effect was recorded in both related priming contexts, which was greater with higher co-occurrence frequency. In the subliminal priming presentation (66-ms SOA), no significant priming effect was shown, regardless of the related priming context. These results show that co-occurrence frequency boosts pure semantic priming effects and are discussed with reference to models of semantic network. 相似文献

The present research evaluates how people integrate factual ‘if then’ and semifactual ‘even if’ conditional premises in an inference task. The theory of mental models establishes that semifactual statements are represented by two mental models with different epistemic status: ‘A & B’ is conjectured and ‘not-A & B’ is presupposed. However, following the principle of cognitive economy in tasks with a high working memory load such as reasoning with multiple conditionals, people could simplify the deduction process in two ways, by discarding: (a) the presupposed case and/or (b) the epistemic status information. In Experiment 1 and Experiment 2, we evaluated each of these hypotheses. In Experiment 1, participants make inferences from two conditionals: two factual conditionals or one factual and one semifactual, with different representations. In Experiment 2, participants make inferences with a factual conditional followed by two different semifactual conditionals that share the same representations but differ in their epistemic status. Accuracy and latency data suggest that people think of both the conjectured and the presupposed situations, but do not codify the epistemic status of either when the task does not require it. The results are discussed through theoretical predictions about how people make inferences from different connected conditionals. 相似文献
