影响直升机飞行员飞入IMC的心理因素——一项基于三十年间NTSB事故报告的研究

通过对美国30年间直升机事故的探索,我们发现与目视气象条件相比较,发生于仪表气象条件下的事故的危害性更大。而在119起与直升机飞行员飞入仪表气象条件有关的事故中,有90起（76%）是飞行员有意飞入的,有29起（24%）是飞行员无意飞入的。进一步的分析发现,动机是影响飞行员有意飞入的首要因素,情景评估是影响飞行员无意飞入的首要心理因素。最后基于相关研究,我们利用模型图比较分析了影响飞行员飞有意和无意入仪表气象条件的心理机制。     

视觉特征提取加工中的认知可塑性

本研究采用“加因素法”研究范式,通过两个实验分别检测20名飞行员和lO名老年被试及其相应控制组在视觉特征提取任务上的认知加工水平,旨在探讨视觉特征提取这一高水平视觉表象加工上的认知可塑性水平。研究结果表明,视觉特征提取加工既表现出了随外界系统训练而发生功能增强的练习效应,也表现出了随年老化过程而发生相应功能显著改变的年龄效应。研究提示,由于受大脑神经细胞活动特性改变的影响,视觉特征提取加工更多地表现出了可塑性或易变性相对较高的认知特性。结合相关的工作基础,研究结果还进一步证实高水平视觉认知加工所表现出的练习效应和年龄效应在大脑神经网络上的分布是不平衡的。本研究不仅对于揭示高水平视觉表象加工的认知特性具有重要的理论意义,而且在实践中对于建立飞行员、宇航员等特殊职业人员的选拔模型以及揭示飞行空间定向障碍的认知机制也具有重要的应用价值。     

视觉表象扫描加工可塑性水平的研究

本研究通过两个实验分别检测20名飞行员和10名老年被试及其相应控制组的表象扫描加工水平,旨在探讨表象扫描这一典型视觉空间认知加工所表现出的可塑性水平。研究结果表明,表象扫描加工水平既没有因外界系统的训练而发生功能增强的练习效应,也未出现随年老化过程所表现出的功能显著下降的年龄效应。研究提示,由于受大脑神经细胞活动特性改变的影响,表象扫描加工能力更多地表现出了其认知加工的相对稳定性或可塑性较低的认知特性。     

National culture and flight deck automation: results of a multination survey

Attitudes regarding flight deck automation were surveyed in a sample of 5,879 airline pilots from 12 nations. The average difference in endorsement levels across 11 items for pilots flying automated aircraft in 12 nations was 53%, reflecting significant national differences in attitudes on all items, with the largest differences observed for preference and enthusiasm for automation. The range of agreement across nations was on average four times larger than the range of agreement across different airlines within the same nation, and roughly six times larger than the range across pilots of standard and pilots of automated aircraft. Patterns of response are described in terms of dimensions of national culture. Implications of the results for development of safety cultures and culturally sensitive training are discussed.

Neuroanatomical correlates of processing in visual and visuospatial working memory

Working memory is traditionally seen as being organised in a modular way with a central executive orchestrating at least two slave systems (phonological loop and visuospatial sketch pad). Neuroanatomical correlates of the visual and visuospatial subsystems and the central executive are discussed in this article. A series of experiments are presented yielding evidence for a differentiation into active and passive processing in working memory as well as their neuroanatomical correlates in the prefrontal cortex. Data, yielding evidence for an interaction and separation of visual and visuospatial working memory are presented and discussed. Further results are presented which suggest a convergence of these two systems with increasing working memory demands. The discussed findings will give new insight in the organisation of visual and visuospatial working memory on the anatomical level.     

Object-based attention and cognitive tunneling

Simulator-based research has shown that pilots cognitively tunnel their attention on head-up displays (HUDs). Cognitive tunneling has been linked to object-based visual attention on the assumption that HUD symbology is perceptually grouped into an object that is perceived and attended separately from the external scene. The present research strengthens the link between cognitive tunneling and object-based attention by showing that (a) elements of a visual display that share a common fate are grouped into a perceptual object and that this grouping is sufficient to sustain object-based attention, (b) object-based attention and thereby cognitive tunneling is affected by strategic focusing of attention, and (c) object-based attention is primarily inhibitory in nature.     

The Moderating Effect of Cognitive Flexibility in the Relationship Between Work Stress and Psychological Symptoms in Korean Air Force Pilots

Stress is closely associated with not only physical illness but also with indices of psychological maladjustment. However, such negative mental health outcomes may vary depending on the individual’s cognitive style, or perception of stress. Air force pilots are particularly vulnerable to experience a high degree of stress as they are required to conduct missions while simultaneously monitoring for safety in complex and uncertain flight situations. It can thus be posited that appropriate use of cognitive stress management strategies is one of the crucial competency requirements for pilots. As such, the present study examined the effects of stress on psychological symptoms of Korean Air Force pilots and further investigated the moderating role of cognitive flexibility in this relationship. A total of 192 air force pilots participated in the present study. The results indicated that degree of stress was positively correlated with indices of psychological maladjustment, while cognitive flexibility was negatively associated with psychological symptoms. Furthermore, cognitive flexibility demonstrated a significant moderating effect on the relationship between stress and psychological symptoms. Such results suggest that cognitive flexibility may serve as a protective factor in the potential effects of stress on psychological adjustment. Implications and suggestions for future research are discussed.

风险知觉是飞行员进行正确风险管理的核心,对保证航空安全具有重要作用。本文首先对不同研究者对飞行员风险知觉的概念进行综述,又与传统的知觉和危险知觉进行了区分。其次,文章简明地介绍了飞行员风险知觉的测量方法,包括外显的主观评价法、飞行模拟器测验、内隐联想测验等方法,分析各种方法的内容与其优缺点。最后,本文分别从认知理论取向和组织文化理论取向两个方面来探讨飞行员风险知觉的研究,并针对两种理论取向,提出相应的未来研究方向。     

The effect of brief auditory stimuli on visual apparent motion

When two discrete stimuli are presented in rapid succession, observers typically report a movement of the lead stimulus toward the lag stimulus. The object of this study was to investigate crossmodal effects of irrelevant sounds on this illusion of visual apparent motion. Observers were presented with two visual stimuli that were temporally separated by interstimulus onset intervals from 0 to 350 ms. After each trial, observers classified their impression of the stimuli using a categorisation system. The presentation of short sounds intervening between the visual stimuli facilitated the impression of apparent motion relative to baseline (visual stimuli without sounds), whereas sounds presented before the first and after the second visual stimulus as well as simultaneously presented sounds reduced the motion impression. The results demonstrate an effect of the temporal structure of irrelevant sounds on visual apparent motion that is discussed in light of a related multisensory phenomenon, 'temporal ventriloquism', on the assumption that sounds can attract lights in the temporal dimension.     

Statistical Judgment Formation in Personnel Selection: A Study in Military Aviation Psychology

This study addresses the issue of data combination in personnel selection. In a pilot study for the selection of trainee pilots for the German Luftwaffe, 99 applicants were assessed using a comprehensive battery of tests that measured inductive thinking, spatial thinking, attentiveness, visual and verbal short-term memory, sensorimotor coordination, and reactive stress tolerance. The global evaluation of the applicants' performance in a flight simulator served as an external criterion. The predictive validity of this test battery was checked by carrying out a discriminant analysis as well as by calculating a neural network. The 2 methods were compared with regard to their classification rate, stability, and separation of correct and incorrect classifications. The results show that artificial neural networks are useful tools for improving the quality of selection procedures for trainee pilots.     

Pilot personality and crew coordination: implications for training and selection

The performance of pilots can be construed as a product of skill, attitude, and personality factors. Although a great deal of effort within the aviation community has been focused on ensuring technical expertise, and new efforts highlight attitudes associated with crew coordination, personality factors have been relatively unexplored. Further, it is argued that past failures to find linkages between personality and performance were due to a combination of inadequate statistical modeling, premature performance evaluation, and/or the reliance on data gathered in contrived as opposed to realistic situations. The goal of the research presented in this article is to isolate subgroups of pilots along performance-related personality dimensions and to document limits on the impact of crew coordination training between the groups. Two samples of military pilots were surveyed in the context of training in crew coordination. Three different profiles were identified through cluster analysis of personality scales. These clusters replicated across samples and predicted attitude change following training in crew coordination.     

Effects of instruction modality and readback on accuracy in following navigation commands

In 3 experiments, the authors simulated air traffic controllers giving pilots navigation instructions of various lengths. Participants either heard or read the instructions; repeated either all, a reduced form, or none of the instructions; and then followed them by clicking on the specified locations in a space represented by grids on a computer screen. Execution performance for visual presentation was worse than it was for auditory presentation on the longer messages. Repetition of the instructions generally lowered execution performance for longer messages, which required more output, especially with the visual modality, which required phonological receding from visual input to spoken output. An advantage for reduced over full repetition for visual but not for auditory presentation was attributed to an enhanced visual scanning process.     

表象旋转加工子系统特性的初步研究

通过两个实验分别检测２０名飞行员和１０名老年被试及其相应控制组的表象旋转加工水平,旨在探讨表象旋转这一典型视觉空间认知加工中各子系统所表现出的可塑性和稳定性问题。研究结果表明,在参与表象旋转的三个主要加工子系统中,负责表象转换的子系统既可随系统训练而表现出功能增强的练习效应,也可随年老过程而发生功能衰减的年龄效应。相对而言,形状识别和确认两上子系统则受练习和年老因素影响较小。本研究提示,由于受大脑     

类别与数量空间关系识别加工中的练习效应研究

本研究通过检测20名飞行员及其控制组的视觉空间关系识别中的认知加工水平,旨在探讨视觉空间关系识别中的类别关系和数量关系加工子系统所表现出的练习效应水平的高低。研究结果表明,在参与视觉空间关系判断的两个典型加工子系统中,负责数量(坐标)空间关系判断的加工子系统随系统训练而表现出功能增强的练习效应。相对而言,涉及类别空间关系判断的加工子系统则较少受到练习的影响。研究揭示,由于受大脑神经解剖结构特点以及加工任务性质的影响,练习效应在神经网络上的分布是不平衡的。相对于类别空间关系加工子系统,数量空间关系加工子系统更多地表现出了练习效应这一典型的认知神经加工特性。     

飞行中惊吓和惊奇的管理——拓展的Landman模型

在飞行活动中,飞行员的惊吓和惊奇反应是导致飞行失控的重要因素。惊吓和惊奇反应可能使飞行员熟练训练过的操作程序和技能被遗忘,取而代之的是不适当的直觉性的行为或草率的决策。现有的使用飞行模拟器的研究表明,Landman模型对减轻飞行员惊吓和惊奇的训练有重要价值。在Landman模型的基础上,我们加入了飞行员心理能力的个体间差别（即拓展的Landman模型）,因此拓展的Landman模型对于飞行员的选拔和训练将具有重要意义。     

相对到达时间任务中飞行员对客体特征与运动特征的分离

相对到达时间任务(RAT)是判断两个运动客体哪个先到达指定目标, 可用来评估个体动态空间能力。采用RAT任务对飞行员与普通被试进行对照研究, 寻求发现两组在运动客体特征和视觉空间运动特征及其相互关系上的处理差异。设计了3个实验分别考察客体颜色、客体大小、运动方向、速率大小、视线方向以及背景特征对判断的影响。结果显示：(1)客体颜色不影响运动客体的相对时间判断, 客体大小、运动方向、速率大小、视线方向以及背景特征影响判断; (2)控制组对显示屏上从左到右的运动客体的相对时间判断好于从右到左任务, 大速率任务判断更好, 对大客体快速行驶而小客体低速行驶时的相对到达时间更易区分, 且与两眼视线方向不一致的运动方向会使控制组判断更难, 运动背景中的目标线特征改变使控制组判断绩效降低; (3)和控制组比, 飞行员反应快正确率高, 其快速判断优势集中体现在从右到左运动以及小速率任务上, 且在不同运动方向和不同速率上的反应时均无差异, 飞行员的处理优势还表现在不受客体大小、视线方向改变和目标线特征改变的影响。结论：飞行员能在变化的空间中准确处理相对速度、相对距离、相对时间等运动信息, 能分离客体大小、背景、运动方向等因素对相对到达时间判断的影响, 在运动空间中飞行员具有较高场独立性认知特征和动态空间处理能力。     

The coleman roberts griffith address: Three myths about applied consultancy work

Abstract

Three recommendations that are commonly made in the applied sport psychology literature are discussed. These three recommendations are : 1) cognitive anxiety is always detrimental to performance and should therefore be reduced whenever possible; 2) outcome goals and ego orientations have a detrimental effect on a number performance-related variables. so that performers should be encouraged to set performance rather than outcome goals; 3) internal visual imagery is more beneficial to performance than external visual imagery. so performers should always be encouraged to use visual imagery from an internal perspective. For each of these recommendations. empirical and experiential evidence is presented which challenges the recommendation. Alternative refinements to the recommendations are discussed.     

EFFECT OF A SPECIFIC NOISE ON VISUAL AND AUDITORY MEMORY SPAN

Messages of visual and aural stimuli (digits) were presented together with a specific noise consisting of different auditory and visual stimuli. The auditory memory span, measured by the amount of digits recalled immediately after presentation, was not at all affected by the interfering visual noise, whereas the visual memory span was found to be significantly reduced by the acoustic noise. The results are interpreted as giving support to the hypothesis on the acoustic nature of information storage in immediate memory. Possible differences in the properties of the visual and auditory peripheral filter are discussed.     

The Effect of Information Display Formats on Helicopter Pilots' Target Acquisition and Flying Performance

This study compared three information display formats for presenting tactical instructions to helicopter pilots for locating targets on a situation display. Verbal (text), graphic (symbols), or numeric (digits) instructions were presented for a subsequent target acquisition search task while subjects were either serving as copilot or simultaneously piloting the aircraft. Reaction times (RTs) to acknowledge the instructions were fastest for the numeric format and slowest for the text format. Once the instructions were understood, subjects searched and located the target in a situation display equally well regardless of format. For all formats, piloting performance was adversely affected and mental workload significantly increased while simultaneously performing the target acquisition search task. Practical implications of the findings are discussed.
