车辆追随条件下驾驶员知觉行人危险的经验优势

危险知觉是指驾驶员在交通情境中对明显危险和潜在危险的识别、预测和反应的认知加工过程,是驾驶员对当前交通情境形成的连续而富于变化的复合认知表征。以往研究表明,对于行人过马路这类明显危险,新手和经验驾驶员危险知觉表现都非常出色。但是当明显危险（行人）和潜在危险（前车制动）并存时,经验驾驶员对明显危险的知觉反应是否会突显出优势呢？本研究通过设置两种交通场景：行人单一危险条件和行人-前车双重危险条件,考察不同经验人群对行人危险的反应及眼动特点。在第一个研究中,使用Tobii T120型眼动仪,通过反应时和眼动结合的方法,考察不同危险场景中,不同驾驶经验对驾驶员知觉行人危险的行为反应数据（反应时和正确率）及眼动指标（平均注视时间和水平搜索广度）的影响。采用2（交通场景：行人场景、行人-前车场景）×3（组别：无驾照组、新手组、经验组）两因素混合实验设计,其中交通场景是组内变量,组别为组间变量。因变量为驾驶员对行人危险进行反应的行为数据（反应时和正确率）及眼动数据（平均注视时间和水平搜索广度）。实验要求被试观看交通场景视频,当发现危险时,立刻按键反应。实验结果表明：在有前车条件下,经验组被试的反应时快于新手组（p=.039）和无驾照组（p=.013）,F(2,30)=3.98,p=.029。无驾照组被试对行人的平均注视时间长于经验组（p=.043）和新手组（p=.024）,F(2,30)=3.39,p=.047,ηp2= .18。无驾照组被试对场景的水平搜索广度均小于经验组（p=.006）和新手组（p=.016）,F(2,30)=5.17,p=.012,ηp2= .26。在第二个研究中,对研究一的数据进行了深入分析,考察双重危险场景中驾驶经验对驾驶员知觉行人危险及信息加工效率的影响。采用2（兴趣区类型：行人、前车）×3（组别：无驾照组、新手组、经验组）两因素混合实验设计,其中兴趣区类型是组内变量,组别为组间变量。因变量为搜索行人和前车时的眼动数据（总注视时间、搜索次数和平均搜索时间）。研究结果表明：经验组驾驶员对前车的总注视时间显著短于新手组（p=.014）和无驾照组（p=.003）,F(2,30)=5.99,p=.006。经验组驾驶员对前车的平均搜索视时间显著短于新手组（p=.014）和无驾照组（p=.004）,F(2,30)=5.50,p=.009。在有前车条件下,控制了性别、年龄后,驾驶员对前车的平均搜索时间越长,对行人的危险反应时越长（β=.393,p＜0.05,R2=.308）。这些结果说明：无经验和新手驾驶员糟糕的搜索行为不仅仅是由于操作抢夺认知资源或者情绪紧张导致的。危险的信息加工效率更低,搜索模式不够灵活,也是导致新手驾驶员行人碰撞事故率更高的原因之一。驾驶员培训有助于提高驾驶员对明显危险的信息加工效率和搜索模式灵活性。积累更多的驾驶经验可以提升驾驶员对潜在危险的的视觉搜索和注意资源分配效率,从而加快危险反应时间。未来的驾驶员培训应加强对新手驾驶员搜索技能的培训,并持续提供更多的驾驶员继续教育机会。     

专家与新手教师对静态课堂教学场景的知觉差异

教师在课堂教学过程中,需要实时监控和加工课堂中的各种信息,以此来调整教学和管理课堂.研究选取9名专家教师和16名师范类研究生,采用专家、新手教师对比的范式,借鉴场景知觉的研究方法,以静态教学场景和非教学场景作为刺激材料,利用眼动技术,探讨了教学经验对课堂教学场景知觉的影响.结果发现,相对于新手,专家对静态课堂教学场景的注视次数更多,总注视时间更长;对于不同的场景类型,非教学场景受到的注视次数更多;专家对于非教学场景的注视次数要多于教学场景,但是平均注视时间少于教学场景;专家对非教学场景的总注视时间长于新手.研究表明,专家对非教学场景采取的是多次注视但每次注视时间短的策略,体现的是一种快速扫描的注视模式,而对教学场景采取的是少量注视但每次注视时间长的策略,体现的是认真观看的注视模式.

不同呈现方式的网页广告的眼动研究

选择25名视力正常的大学生,用眼动仪记录他们浏览不同呈现方式、不同位置的网页广告的眼动过程。结果发现：1．对于不同呈现方式的网页广告,从记忆成绩看：彩色组显著优于黑白组,两者与动画组没有显著差异;从眼动指标看：动画组和彩色组的注视次数和注视时的明显高于黑白组。2．网页广告的位置对被试的记忆成绩与眼动模式有一定的影响,表现为上部与中部注视次数增加,注视时间长。记忆成绩也表现为差异显著,中部与上部的记忆效果好。     

自我评估的能力与驾驶经验对危险知觉的影响

结合反应时和眼动研究方法,采用驾驶经验2（新手,有经验）×自我评估的能力2（高,低）×危险类型2（明显,隐藏）的混合实验设计,探索驾驶员驾驶能力的自我评估和驾驶经验对危险知觉及视觉注意的影响。采用驾驶能力量表和基于动态交通视频的危险知觉任务对86名驾驶员测试,并使用Tobbi T120记录眼动数据。结果发现,新手和有经验驾驶员自我评估的能力与危险知觉反应时间之间相关不显著,这说明两组驾驶员对自己驾驶能力的认识和评估不准确。有经验驾驶员对两类危险的反应比新手快。新手自我评估的能力过高,他们对两类危险的反应比同龄驾驶员和有经验驾驶员慢。然而,有经验驾驶员自我评估的能力与危险知觉反应时间之间不存在显著差异。此外,与新手相比,有经验驾驶员对两类危险的首次注视较快,总注视时间更长。与同龄驾驶员相比,新手自我评估的能力过高,他们对危险的首次注视较慢,对危险的总注视时间更少。这些研究结果表明,新手自我评估的能力过高,可能会提高他们的风险接受阈限,由此降低了他们对危险的反应速度。未来驾驶训练应当采取措施减少新手对驾驶能力的自我评估偏见,改善他们的视觉搜索模式以降低事故风险。

The dynamics of team coordination: A social network analysis as a window to shared awareness

Shared awareness was studied in one novice and one expert basketball team during real games. Teams were considered dynamic social networks with team members as nodes and members’ awareness of other members during ongoing performance as relations. Networks, and changes to them across games, were analysed at different levels of organization using social network analysis to identify patterns of awareness within the teams. The results showed that one team member in each team often heeded, or was heeded by, his teammates, indicating his leadership role in coordinating the team. Also, expert team members had a low level of awareness of their teammates, which may be explained by implicit coordination processes. Finally, there was less variability in intra-team relations in the expert (vs. novice) team, which may be explained by the enhanced ability of the expert team to achieve and maintain an optimal level of awareness during the game. At a practical level, teams might be alerted during performance when their network of connections approaches connectedness thresholds that predict coordination breakdowns, affording online regulation of team processes. Future studies should explore the generalizability of these early findings using larger samples.     

An especial skill: Support for a learned parameters hypothesis

We tested the ‘learned parameters’ hypothesis as an explanation of the ‘especial skill effect’. Outcome attainment and movement kinematics were recorded for 10 expert and 10 novice players performing basketball free-throw shots at five distances (11-19 ft) with a regular and heavy weight basketball. As predicted, experts performed better than expected relative to the regression equation at the 15 ft, free-throw line with the regular basketball, supporting the ‘especial skill effect’. This effect was not present for the experts when shooting with the heavy ball. Novices did not show an advantage at the free-throw line when performing with either ball. Although the outcome attainment scores support the ‘learned parameters’ hypotheses, kinematic analysis failed to identify differences in the movement pattern for the especial skill, suggesting that these skills (i.e., shooting at different distances) are not governed by separate motor programs.     

Expertise and the perception of kinematic and situational probability information

Two experiments were conducted on the nature of expert perception in the sport of squash. In the first experiment, ten expert and fifteen novice players attempted to predict the direction and force of squash strokes from either a film display (occluded at variable time periods before and after the opposing player had struck the ball) or a matched point-light display (containing only the basic kinematic features of the opponent's movement pattern). Experts out-performed the novices under both display conditions, and the same basic time windows that characterised expert and novice pick-up of information in the film task also persisted in the point-light task. This suggests that the experts' perceptual advantage is directly related to their superior pick-up of essential kinematic information. In the second experiment, the vision of six expert and six less skilled players was occluded by remotely triggered liquid-crystal spectacles at quasi-random intervals during simulated match play. Players were required to complete their current stroke even when the display was occluded and their prediction performance was assessed with respect to whether they moved to the correct half of the court to match the direction and depth of the opponent's stroke. Consistent with experiment 1, experts were found to be superior in their advance pick-up of both directional and depth information when the display was occluded during the opponent's hitting action. However, experts also remained better than chance, and clearly superior to less skilled players, in their prediction performance under conditions where occlusion occurred before any significant pre-contact preparatory movement by the opposing player was visible. This additional source of expert superiority is attributable to their superior attunement to the information contained in the situational probabilities and sequential dependences within their opponent's pattern of play.     

Classical pattern recall tests and the prospective nature of expert performance

It is well established that experts are particularly adept at recalling and/or recognizing the key features of domain-relevant patterns. We compared the recall performance of expert and novice basketball players when viewing static and moving patterns. A novel method of analysis was used where the accuracy of the participants in recalling player positions was compared to actual player positions both at the final frame of pattern presentation and at 50 successive 40 ms increments thereafter. Experts encoded the locations of the players in both the static and moving patterns significantly further in advance of their actual finishing point than did nonexperts. Experts' use of an anticipatory encoding process, which was of a magnitude unmatched by nonexperts, suggests that many previous investigations may have underestimated the extent of the expert advantage in pattern recall.

The Influence of Expertise on Maritime Driving Behaviour

We compared expert and novice behaviour in a group of participants as they engaged in a simulated maritime driving task. We varied the difficulty of the driving task by controllling the severity of the sea state in which they were driving their craft. Increases in sea severity increased the size of the upcoming waves while also increasing the length of the waves. Expert participants drove their craft at a higher speed than novices and decreased their fixation durations as wave severity increased. Furthermore, the expert participants increased the horizontal spread of their fixation positions as wave severity increased to a greater degree than novices. Conversely, novice participants showed evidence of a greater vertical spread of fixations than experts. By connecting our findings with previous research investigating eye movement behaviour and road driving, we suggest that novice or inexperienced drivers show inflexibility in adaptation to changing driving conditions.

An expert–novice comparison of feature choice

Perceptual experts have learned to rapidly and accurately perceive the structural regularities that define categories and identities within a domain. They extract important features and their relations more efficiently than novices. We used fingerprint examination to investigate expert–novice differences in feature choice. On each fingerprint within our set, experts and novices selected one feature they thought was most useful for distinguishing a particular print and one feature they thought was least useful. We found that experts and novices often differed in the features they chose, and experts tended to agree more with each other. However, any such expert–novice difference appeared to depend on the image at hand typically emerging when salient or more conspicuous features of a fingerprint were unclear. We suggest that perceptual training ought to direct attention to useful features with the understanding that what is useful may change depending on the clarity of the stimuli.     

The influence of motor expertise and motor experience on action and actor recognition

Two experiments examined whether different levels of motor and visual experience influence action perception and whether this effect depends on the type of perceptual task. Within an action recognition task (Experiment 1), professional basketball players and novice college students were asked to identify basketball dribbles from point-light displays. Results showed faster reaction times and greater accuracy in experts, but no advantage when observing either own or teammates’ actions compared with unknown expert players. Within an actor recognition task (Experiment 2), the same expert players were asked to identify the model actors. Results showed poor discrimination between teammates and players from another team, but a more accurate assignment of own actions to the own team. When asked to name the actor, experts recognised themselves slightly better than teammates. Results support the hypothesis that motor experience influences action recognition. They also show that the influence of motor experience on the perception of own actions depends on the type of perceptual task.
