本研究分别在无时间压力和有时间压力的条件下,通过两个实验探究了图标语义距离?目标数量以及目标类型对雷达界面信息工作记忆的影响?结果发现无时间压力下图标语义距离在工作记忆的编码提取上没有差异,而有时间压力下,强语义图标相较于弱语义图标在工作记忆的提取上具有优势;且无论是在无时间压力下还是有时间压力下,工作记忆容量最佳为3个目标项;对敌机的提取时长于友机长于不明飞行物?结果表明仅在有时间压力下强语义图标在信息提取上具有优势,验证了工作记忆容量的限制,为雷达界面的设计提供了参考意见? 相似文献

Objective: We examined effects of daily rumination and suppression in response to stressors on objective and subjective sleep among mothers.Design: Participants were 183 mothers, including chronically stressed mothers of children with an autism spectrum disorder (M-ASD; n = 92) and age-matched mothers of neurotypical children (M-NT; n = 91). In an intensive longitudinal design, participants provided reports of daily rumination and suppression, nightly objective actigraphy-defined sleep and nightly subjective sleep quality for seven consecutive days at baseline, 9 months and 18 months.Main Outcome Measures: Total sleep time, sleep fragmentation, sleep onset latency, and subjective sleep quality.Results: Among M-NT with above average depressive symptoms, higher daily rumination was associated with shorter total sleep time. Rumination was associated with more sleep fragmentation among M-NT at the trend level. Rumination was not associated with sleep onset latency among M-NT, or with any sleep outcomes among M-ASD. Suppression was not associated with any sleep outcomes.Conclusion: We provide novel evidence of the effect of rumination on objectively measured sleep duration among M-NT. Coping was not related to sleep among M-ASD. Given the prevalence of poor sleep among mothers, future work should examine modifiable factors perpetuating sleep disturbance. 相似文献

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in both contiguous and discrete spatial configurations. Response time (RT) and accuracy were recorded, and evidence of predictive monitoring was assessed via first fixations and refixations of target‐predictive stimuli. RTs to target onsets and evidence of predictive monitoring were reduced in dual‐target, relative to single‐target, conditions. Further, predictive monitoring did not speed RTs but was influenced by display configuration. In particular, discrete displays impaired monitoring for number targets in the dual‐target condition. Implications exist for real‐world visual tasks involving multiple target categories and for visual display design. 相似文献

Public service employees work in occupations that are accompanied with high psychosocial risks. Police, firefighters, and paramedics are increasingly being confronted with argumentative, conflicting bystanders that frustrate them in executing their task. We developed a resource‐enhancement intervention and tested its usefulness for securing employees’ effective functioning and well‐being in bystander conflict. In a simulation‐based pre‐test post‐test control group design, paramedics in the intervention condition received training about how to increase their resources in terms of conflict management efficacy, perspective taking, task support, and emotional support. For those in the control condition, no such training was provided. Comparing pre‐ and post‐test measures (n = 81) of the participants in the intervention and control groups, we found evidence that the intervention successfully increased employees’ resources over time. Moreover, we found considerable support for a positive link between these resources and employees’ affective well‐being and job dedication. Thus, our study suggests that a resource‐enhancing intervention can serve as an important means to protect public service employees against the deleterious effects of bystander conflict.
Practitioner points
- A resource‐enhancing intervention can protect public service employees against the deleterious effects of bystander conflict.
- Resources related to dealing with a hindering bystander, as well as resources facilitating the continuation of the primary task, are positively associated with employees’ affective well‐being, job dedication, and job performance.

Habit and time in nineteenth-century French philosophy: Albert Lemoine between Bergson and Ravaisson
Mark Sinclair 《British Journal for the History of Philosophy》2018,26(1):131-153
This paper shows how reflection on habit leads in nineteenth-century French philosophy to Henri Bergson’s idea of duration in 1888 as a non-quantifiable dimension irreducible to time as measured by clocks. Historically, I show how Albert Lemoine’s 1875 L’habitude et l’instinct was crucial, since he holds – in a way that is both Ravaissonian and Bergsonian avant la lettre – that for the being capable of habit, the three elements of time are fused together. For that habituated being, Lemoine claims, it is not true to say that the past is no longer, nor even that the future is not yet. This historical link between Ravaisson and Bergson, however, only sharpens the philosophical question of how a dynamic conception of habit involves and requires a conception of real duration, of a temporality more original than clock-time, and, conversely, of how reflection on duration prior to clock-time involves a notion of habit. With reference to the work of Gilles Deleuze, the paper concludes by showing that there is an internal connection between these two grand philosophical themes of nineteenth- and then twentieth-century French thought: habit and time. 相似文献

The present study explored the influence of part-set cues in semantic memory using tests of “free” recall, reconstruction of order, and serial recall. Nine distinct categories of information were used (e.g., Zodiac signs, Harry Potter books, Star Wars films, planets). The results showed part-set cueing impairment for all three “free” recall sets, whereas part-set cueing facilitation was evident for five of the six ordered sets. Generally, the present results parallel those often observed across episodic tasks, which could indicate that similar mechanisms contribute to part-set cueing effects in both episodic and semantic memory. A novel anchoring explanation of part-set cueing facilitation in order and spatial tasks is provided. 相似文献
