类别型状态不确定独立否定句的加工机制：来自眼动实验的证据

探讨类别型状态不确定独立否定句(如“裙子不是蓝色的”)的动态表征过程。实验1和实验2分别仅给被试提供“与事件备择选项一致的图片” (红色裙子)和“含有否定标签的与事件否定状态一致的图片” (含有否定标签的蓝色裙子); 实验3同时提供以上两种选项。结果发现：3个实验中被试在早期均对“与事件否定状态一致的图片”注视概率更高, 在晚期阶段, 实验1仅对“与事件备择选项一致的图片” 注视概率更高, 实验2和实验3均仅对“含有否定标签的与事件否定状态一致的图片”注视概率更高, 并且选择为事件的最终状态; 实验4的评定结果表明, 当被试有充裕时间完成任务时, 37名评定者中有30名选择“与事件备择选项一致的图片”为事件的最终状态。4个实验的结果为锚激活与限制满足模型和抑制假设提供了进一步证据。

A lower bound to the probability of choosing the optimal passing score for a mastery test when there is an external criterion

Recently there has been interest in the problem of determining an optimal passing score for a mastery test when the purpose of the test is to predict success or failure on an external criterion. For the case of constant losses for the two error types, a method of determining an optimal passing score is readily derived using standard techniques. The purpose of this note is to describe a lower bound to the probability of identifying an optimal passing score based on a random sample ofN examinees.The work upon which this publication is based was performed pursuant to a grant [contract] with the National Institute of Education, Department of Health, Education and Welfare.

Quantifying drivers’ comfort-zone and dread-zone boundaries in left turn across path/opposite direction (LTAP/OD) scenarios

The aim of this study is to quantify drivers’ comfort- and dread-zone boundaries in left-turn-across-path/opposite-direction (LTAP/OD) scenarios. These scenarios account for a large fraction of traffic fatalities world-wide. The comfort zone is a dynamic spatiotemporal envelope surrounding the vehicle, within which drivers feel comfortable and safe. The dread zone, a novel concept, describes a zone with a smaller safety margin that drivers will not voluntarily enter, but can push themselves into when conditions provide additional motivation (e.g., when hurried). Quantifying comfort- and dread-zone boundaries in the context of turning left before or after an oncoming vehicle has the potential to inform and improve both the design and driver acceptance of advanced driver assistance systems (ADAS) and autonomous vehicles.Using a within-subject design, a test-track experiment was conducted with drivers turning an instrumented vehicle left across the path of an oncoming vehicle. The oncoming vehicle was a self-propelled full-sized computer-controlled balloon vehicle going straight at a constant speed (50 km/h). The driver assumed full control of the instrumented vehicle approximately 20 m before the intersection and had to make the decision to turn left before or after the oncoming balloon vehicle. There were two experimental conditions, comfortable driving and hurried driving. Measures for each turn included post-encroachment time (PET), lateral acceleration, and self-reports of comfort and risk. Drivers consistently accepted shorter time gaps and higher lateral accelerations when hurried. We interpret these findings to suggest that drivers invoke two dynamic, contextually-defined safety margins. The first is the comfort-zone boundary, a limit which drivers do not voluntarily cross without extra motives. The second is the dread-zone boundary, a more distant limit which drivers do not voluntarily cross even with extra motives. Grouping the responses (high/low) to the driver behavior questionnaire (DBQ) improved the ability to predict the dread-zone boundary PET given the comfort-zone boundary PET.     

Influence of the median opening length on driving behaviors in the crossover work zone—A driving simulation study

Work zone safety has been a major concern for drivers and transportation agencies. Considering the severe consequences of crossover work zone crashes coupled with the limited literature on the median opening length, this paper aims to investigate the influence of the median opening length on driving behaviors from a behavioral perspective in crossover work zones. A driving simulation study with 32 participants was carried out to investigate the driving performance by metrics (speed, acceleration, maximum steering wheel speed, and lane-changing trajectory) with respect to five median opening lengths. The significant differences of each driving performance metric among various median opening lengths were found in the process of crossing through the median opening on the entrance by-pass and exit by-pass. The results indicated that drivers’ speeds were always higher than the speed limits for all median opening lengths. A narrower median opening may induce risky driving behaviors such as sharp deceleration and decelerating while lane-changing, which may increase speed variance. When crossing through the median opening with a larger length, high speed variance, sluggish lane-changing operations, and improper lane-using behaviors were observed because the excessive lane-changing space provided by the larger median opening length would decrease the situation awareness and increase the speed preference heterogeneity among drivers. Finally, some traffic management strategies were proposed, which can improve the safety and mobility of crossover work zones and further provide a basis for the formulation of related standards.     

Was it a clutch performance? A qualitative exploration of the definitional boundaries of clutch performance

ObjectivesClutch performance refers to positive performance under pressure. Definitions of clutch performance, however, differ on the performance level required to constitute this phenomenon. This definitional divergence centres on whether clutch performance requires increased, or maintained, performance. Further, it is unclear what performance benchmark (e.g., season average) clutch performances should be compared against. Accordingly, this study aimed to explore athletes’ perceptions of what performance level is required for clutch performance, and what performance benchmarks clutch performances are compared against.MethodTwenty-four athletes (M_age = 27.13 years) participated in event-focused, semi-structured interviews soon after a positive performance under pressure (M = 93 h later). Data were analysed utilising reflexive thematic analysis.ResultsThree themes were generated: (1) clutch performance is assessed against goal achievement, suggesting that the achievement of self-referenced goals is the primary indicator athletes’ use to assess clutch performance; (2) clutch performance exists on a performance spectrum, suggesting that the performance level required for clutch performance differs due to the appraisal of pressure and the athletes’ own goals; and (3) different benchmarks are used to assess clutch performance, suggesting that athletes’ may draw on both previous performances, and the performance itself, to assess clutch performance.ConclusionsThis study suggested that clutch performance is a situational and context-dependent phenomenon. Specifically, athletes assessed clutch performance on the extent to which they perceived achievement of self-referenced goals. Defining clutch performance in this manner may resolve tensions between existing definitions, and further, may facilitate development of a measure of clutch performance.

Panpsychism,The Combination Problem,and Plural Collective Properties

Panpsychism claims that each fundamental entity is conscious, but then faces the problem of how such entities combine to make up our ordinary consciousness. In this paper, I show how panpsychism can avoid this so-called combination problem by taking seriously plural collective properties at the fundamental level.     

Comparing examinees to a control

When comparing examinees to a control, the examiner usually does not know the probability of correctly classifying the examinees based on the number of items used and the number of examinees tested. Using ranking and selection techniques, a general framework is described for deriving a lower bound on this probability. We illustrate how these techniques can be applied to the binomial error model. New exact results are given for normal populations having unknown and unequal variances.The work upon which this publication is based was performed pursuant to a grant [Grant No. NIE-G-76-0083] with the National Institute of Education, Department of Health, Education and Welfare.
