The effect of sample duration and cue on a double temporal discrimination

To test the assumptions of two models of timing, Scalar Expectancy Theory (SET) and Learning to Time (LeT), nine pigeons were exposed to two temporal discriminations, each signaled by a different cue. On half of the trials, pigeons learned to choose a red key after a 1.5-s horizontal bar and a green key after a 6-s horizontal bar; on the other half of the trials, they learned to choose a blue key after a 6-s vertical bar and a yellow key after a 24-s vertical bar. During subsequent test trials, they were exposed to the horizontal or vertical bar, for durations ranging from 1.5 to 24 s, and given a choice between novel key combinations: red vs. yellow, or green vs. blue. Results showed a strong effect of sample duration—as the test signal duration increased, preference for green over blue increased and preference for red over yellow decreased. The effect of sample cue was obtained only on the green-blue test trials. These effects are discussed in light of SET and LeT.     

景颇族初中生的民族社会化觉察及其特征

民族社会化觉察是指少数民族孩子对父母向他们传递的有关民族特征信息的认知。采用问卷调查、情境实验和故事补全任务考察景颇族初中生对母亲传递的民族社会化信息的觉察及特征。结果表明：(1)景颇族初中生觉察到的民族社会化信息包含促进和睦、文化社会化、促使不信任和偏见准备; (2)景颇族初中生对不同信息的觉察存在差异, 对促进和睦的觉察显著多于文化社会化和偏见准备, 对促使不信任的觉察最少; (3)在冲突情境中, 有无偏见线索影响被试对偏见准备的觉察; (4)被试的民族社会化觉察存在性别差异, 女生更多地觉察到促进和睦, 男生更多地觉察到促使不信任。整个研究表明, 青少年的民族社会化觉察存在着文化差异, 与美国少数族裔青少年觉察到母亲偏重于传递文化社会化、偏见准备不同, 景颇族初中生觉察到母亲偏重于传递促进和睦。     

文本表述结构对空间维度非线索更新的影响

采用实时窗口阅读技术,探讨阅读中文本表述结构在情境模型空间维度非线索更新中的作用。实验一结果表明,阅读中,如果文本叙述中采用以人为参照的描述方式,那么可以促进相应空间设置内物体的实时更新。实验二考察了空间设置不同程度的描述对空间信息加工中的影响,结果发现,相对于对空间设置的简单描述,在文本中对空间设置进行精细阐述更有利于情境模型空间维度非线索更新的达成。     

模态系统的推理规则的强弱虚实

模态系统的推理规则可以用强弱虚实这四种性质进行分类。在一个系统中这几种性质无论在语形上还是语义上都有一定的联系和区别,有些性质在一个系统的变种或扩充中并不一定保持。     

SPEECH EVENTS, LANGUAGE DEVELOPMENT, AND THE CLINICAL SITUATION

Psychoanalysis brings about psychic change by the mediation of speech. This paper reflects upon the significance of the structure and developmental organisation of the speech event as a verbal and non-verbal unit composed of semantically and prosodically encoded messages, interactions and emotional contact between partners. Spoken words communicate semantic meanings and the affects of a given speech event. Words carry personal emotional meanings which are inseparable from their referential significance. Such emotional meanings are very hard to articulate in words. They are conveyed by the ineffable but essential feelings present in their sound and pronunciation. Speech is an intentionally object-related and emotionally engaging social activity resulting from a child having been spoken to early in life by an adult wanting to establish affective verbal contact. The early organisation and later transformation of the structure of the speech event carries private meanings for each person's listening and speaking stance. A refined understanding of the structural and emotional complexities of verbal communicative exchanges during analysis may enhance the analyst's ability to understand the patient'smanner of participation in the analytic process.     

当前俄罗斯心理学发展的现状和趋势

苏联解体后,伴随俄罗斯社会政治的变革,俄罗斯心理学也发生了相应的变化,其现状和趋势主要表现为:继承了苏联心理学的宝贵遗产,加强了维果茨基心理学思想的研究,形成了对心理现象的统一认识,出现了轻基础研究重应用研究的倾向,产生了许多新的分支学科.     

Situation Awareness and Workload in Aviation

A pilot faces special challenges imposed by the need to control a multivariate lagged system in a heterogeneous multitask environment. The time lags between critical variables require prediction in an uncertain world. The interrelated concepts of situation awareness and workload are central to aviation psychology. Three components of situation awareness are spatial awareness, system awareness, and task awareness. Each of these components has real–world implications, spatial awareness for instrument displays, system awareness for keeping the operator informed about actions that have been taken by automated systems, and task awareness for attention and task management. Task management is directly related to mental workload, as the competing demands of tasks for attention exceed the operator's limited resources.     

儿童冒险行为的影响因素

冒险行为是个体面对风险情境时的行为意愿,是一种特殊类型的决策。儿童的冒险行为受到个体、家庭、社会-情境三个方面的影响。个体因素方面,儿童的性别和年龄会影响他们对风险的知觉、对受伤风险的估计和对行为后果的归因;认知决策能力和预期情绪体验则影响到儿童对风险情境的判断。家庭因素方面,父母和兄姐是影响儿童冒险行为的重要他人,父母的态度和反应会直接影响儿童的冒险行为,而兄姐的言语和行为会改变他们的风险决策。从社会-情境的角度来看,风险情境会对儿童的冒险决策带来压力,有同伴在场时会促使儿童更倾向于参与冒险。综合分析并探讨冒险行为的各个影响因素及其产生机制,对提出合理干预措施,减少儿童因冒险行为而导致的意外伤害具有重要意义。     

Caught in the act: How extraverted and introverted friends communally cope with being recorded

This study explored how close friends who were similar or opposite on extraversion communally coped with being put on the spot to produce a recorded conversation. Participants were 50 pairs of same-sex college-age friends (54% female) who explicitly discussed the fact that their conversation was being recorded. The initial ‘on-stage’ episode emerged consistently earliest for extraverted dyads, and the majority of their episodes quickly diverted the on-stage moment. Dyads that included at least one introvert engaged in more extensive assortments of on-stage maneuvers, including research talk, soothing, and joking. In introvert–extravert dyads the extravert usually initiated and ended these episodes. Implications are discussed for understanding how personality is reciprocally implicated in managing shared everyday problems.
