航线飞行技术性技能与航线飞行阶段任务的关系研究

通过文献、专家意见和问卷调查,构建了现代航线飞行技术性技能多维评价量表。对118名航线飞行员测评数据的验证性因素分析表明,由倾斜控制、偏航控制、平衡控制和速度控制构成的4维模型在飞行准备/滑行、起飞/爬升、巡航、下降/进近/着陆四个飞行阶段均有较好的信度和效度;多元回归分析发现,各维度对不同航线飞行阶段任务均有显著影响。航线飞行技术性技能评价量表的构建为现代航线飞行员选拔与训练、机组驾驶行为规范性评价以及飞行安全管理考核模式的设计奠定了一个良好的工作基础。     

The sad, the angry, and the asymmetrical brain: dichotic listening studies of negative affect and depression

Dichotic Listening (DL) is a valuable tool to study emotional brain lateralization. Regarding the perception of sadness and anger through affective prosody, the main finding has been a left ear advantage (LEA) for the sad but contradictory data for the anger prosody. Regarding an induced mood in the laboratory, its consequences upon DL were a diminished right ear advantage (REA) for the induction of sadness and an increased REA for the induction of anger. The global results fit with the approach-withdrawal motivational model of emotional processing, pointing to sadness as a right hemisphere emotion but anger processed bilaterally or even in the left hemisphere, depending on the subject's preferred mode of expression. On the other hand, the study of DL in clinically depressed patients found an abnormally larger REA in verbal DL tasks which was predictive of therapeutic pharmacological response. However, the mobilization of the available left hemisphere resources in these responders (reflected in a higher REA) would indicate a remission of the episode but would not assure the absence of new relapses.     

宗教心理学在临终关怀中的应用

宗教心理学有助于缓解临终患者的痛苦,但应通过把握宗教共同精神而非具体程序,将天堂和神两大要素剥离后,在合理范围有条件地使用。东西方主流宗教心理特点不同,西方主流宗教不适合我国国情。本土儒教和道教不能有效满足临终关怀应用前提,而大小乘佛教创造性结合后的心理模式或更适合在临终关怀中使用,更适应我国国情。     

中文阅读中基于字和词的跳读与返回抑制:来自眼动方面的证据

该研究通过记录读者自然阅读中的眼动过程,对比考察了中文阅读中基于字和词的跳读与返回抑制事件。结果发现:(1)跳读事件并不影响眼跳前注视的持续时间,说明阅读过程中的眼跳计划被同时制定;(2)在一定范围内,眼跳幅度越大,跳读后注视的持续时间越长,这反映了基本的预视效应;(3)中文阅读中存在返回抑制现象,但这个现象产生的基本依据是低级的空间线索,而非词汇语义单元。     

Medial prefrontal cortex is selectively involved in response selection using visual context in the background

The exact roles of the medial prefrontal cortex (mPFC) in conditional choice behavior are unknown and a visual contextual response selection task was used for examining the issue. Inactivation of the mPFC severely disrupted performance in the task. mPFC inactivations, however, did not disrupt the capability of perceptual discrimination for visual stimuli. Normal response selection was also observed when nonvisual cues were used as conditional stimuli. The results strongly suggest that the mPFC is not necessarily involved in the inhibition of response or flexible response selection in general, but is rather critical when response selection is required conditionally using visual context in the background.     

Book Reviews

Building upon previous research on student attitudes to Christianity, an instrument that assesses the perceptions on four Attitude to Christianity dimensions (viz., Attitude to Prayer, God, and Jesus; Attitude to the Bible; Attitude to Christian Practice; and Attitude to Social Justice) was developed. A sample of 1,317 students in Australian Catholic high schools was used to validate this instrument. Comparisons of attitudes to Christianity between students in Catholic boys', girls', and coeducational schools and between students of different age and gender illustrated the usefulness of these four scales.     

Perception of acoustically presented time series with varied intervals

Data from three experiments on serial perception of temporal intervals in the supra-second domain are reported. Sequences of short acoustic signals (“pips”) separated by periods of silence were presented to the observers. Two types of time series, geometric or alternating, were used, where the modulus 1 + δ of the inter-pip series and the base duration T_b (range from 1.1 to 6 s) were varied as independent parameters. The observers had to judge whether the series were accelerating, decelerating, or uniform (3 paradigm), or to distinguish regular from irregular sequences (2 paradigm). “Intervals of subjective uniformity” (isus) were obtained by fitting Gaussian psychometric functions to individual subjects' responses. Progression towards longer base durations (T_b = 4.4 or 6 s) shifts the isus towards negative δs, i.e., accelerating series. This finding is compatible with the phenomenon of “subjective shortening” of past temporal intervals, which is naturally accounted for by the lossy integration model of internal time representation. The opposite effect observed for short durations (T_b = 1.1 or 1.5 s) remains unexplained by the lossy integration model, and presents a challenge for further research.     

Is it culture or is it language? Examination of language effects in cross-cultural research on categorization

Differences in reasoning styles between Chinese and European Americans held even when controlling for the language of testing. Bilingual Chinese organized objects in a more relational and less categorical way than European Americans, whether tested in English or in Chinese. Thus, culture affects categorization independent of the testing language. Nevertheless, language affected some Chinese bilinguals' categorization. The responses of Chinese from the Mainland and Taiwan were more relational when tested in Chinese than when tested in English. Responses of Chinese from Hong Kong and Singapore were equally relational when tested in Chinese and in English. Age and context of learning English are discussed to explain the differential language effects among different Chinese groups. Theoretical and methodological implications are discussed.     

Study time effects in recognition memory

We empirically tested the assumption that study time increases recognition accuracy because the storage of information is better when study time is longer as Shiffrin and colleagues have reported, an assumption common to parallel models of recognition. In the present study with 123 subjects, we examined the effect of item strength on four measures: hit rate, false alarm rate, d', and beta, for a single-word recognition task with longer study times than those usually used in the literature. Analysis indicated significant increase for hit rate and d' and a decrease in false alarm rate, as one goes from weak to stronger study conditions, and a change in ln(beta) when study time is greater than 1 sec. These results suggest that familiarization is one, but not the only, factor underlying the strength-mirror effect.     

Identity and commitment in emergency teams

This paper adopts Tajfel's social identity theory perspective and applies it to the organizational context in order to study emergency intervention teams. Specifically, it is intended to explore the kind of social identification (professional, team, or organizational) prevalent among members of these organizations. It is intended, as well, to establish a clear distinction between two related, and often confused, concepts, i.e., organizational identification and commitment, and to discover which identification is more apt to predict the organizational outcomes of organizational citizenship behaviors and satisfaction. Our total sample consisted of 151 participants (firemen of the Madrid municipality and members of the army). It was found that organizational identification, as a kind of social identification, is different from organizational commitment, and that it is not its base nor one of its components, and that organizational identification, much as professional one, helps to explain peoples' behavior in organizations.
