Research Notes

Abstract

The purpose of the present study was to conduct a preliminary criterion validity assessment of the Athletic Motivation Inventory (AMI). Subjects were 649 ice hockey players who were eligible for the National Hockey League (NHL) entry draft. Each player was rated for the dependent measure, psychological strength, by at least one of three NHL scouts from one team. This criterion measure was based on the observation of on-ice play. The data were analyzed using three independent multiple regression analyses, one for each scout, with the eleven AMI subscales as predictor variables. The results show that less than four percent of the variance in scout ratings was accounted for by AMI scores. The data are interpreted as showing that on-ice behaviors inferred by NHL scouts to represent psychological strength have little relationship to what the AMI measures. Finally, the data are discussed for their relevance to current NHL entry draft screening procedures and to future validity research.     

Perception of symmetry and repetition within and across visual shapes: Part-descriptions and object-based attention

In five experiments, we investigated the detection of symmetry (i.e., translation plus reflection) or repetition (i.e., translation alone) between two vertical jagged contours. The complexity of the two contours was manipulated, as was their figure-ground assignment; the two contours either belonged to a common object "inside" them, to two separate objects "outside" them, or to two separate objects each to the right of one contour. Replicating Baylis and Driver (1994), symmetry judgements were unaffected by contour complexity when made within a single shape, implying a parallel process operating efficiently across contour discontinuities. However, all the other conditions yielded substantially slower judgements as complexity increased, suggesting either effortful point-by-point comparisons, or a highly inefficient parallel process. In agreement with Baylis and Driver (1995a), symmetry perception was harder when figure-ground assignment turned convexities along one contour into concavities along the other contour; and likewise for repetition detection. However, even when convex parts matched between the two contours, judgements were still affected by complexity unless they belonged to a common object. This supports Baylis and Driver's (1993) proposal that effortless comparisons for the layout of multiple convex parts can only be made within single perceptual objects.     

意外考试悖论的博弈分析

本文从博弈的角度分析了意外考试悖论,指出了以往解决方案的不足,给出了一种新的方案。根据这个新方案,考试悖论的推理中使用了倒推法和弱下策反复剔除法。本文接着讨论了这些博弈推理方法的不足。然后把这个新的博弈方案用到卡片悖论和方格悖论这些考试悖论的变种里。最后指出,在考试悖论里,比起倒推法,弱下策剔除法是引起悖论的更根本的原因。     

汉字形码和音码的整体性对部件识别的影响

本实验从分析汉字整体知觉的具体表现形式入手,通过三个实验探讨字的整体知觉对部件知觉的影响。实验一以分解方式为变量,考查字形整体知觉对部件识别的影响,发现识别不同结构的字的部件之活动受知觉分解路线(如顺读或逆读)的影响。作者认为这种分解方式效应很可能跟部位有关。实验二证实了这一分析,并进而认为部位效应又跟部位与字形整体知觉的紧密程度有关。实验三以语音码为变量,发现成字部件的字音与整体字语音一致者(形声字),其分解知觉成绩比不一致者(非形声字)有明显的优势。这意味着,整体字音知觉的单一性对部件知觉的作用。最后,本研究还考查了部件识别法的有效性,并认为在研究知觉的整体与部分关系问题时,该法不失为一种新的实验范型。     

瑞文标准推理测验在我国的修订

为了满足科研与实际工作对团体智力测验的迫切需要,由17个单位组成的全国协作组对瑞文标准推理测验进行了修订。常模团体的建立以1982年全国人口普查资料为依据,按各地区人口分布,各类人员比例取样,共包括年龄跨度从5岁半至70岁以上的5108人。经过标准化的施测手续,测定了1986年中国城市常模。 测验结果的项目分析、信度和效度等技术指标达到或超过了国外同类研究。 研究发现除40岁组外,其他各年龄组均无显著男女差异。本研究还对中国大陆城市青少年的成绩与香港、英国和新西兰相应年龄组的成绩做了比较。     

两例先天性无痛症患者的心理生理特点研究 Ⅱ.对致痛性强刺激的知觉和反应

本工作对两例先天性无痛症患者对于致痛性强刺激的知觉和反应进行了研究(例1女,10岁,例2男,13岁)。对照组为20例正常儿童,性别和年龄均与患儿相匹配。 结果:1),生活中痛:两例患儿均无(包括痛感觉和痛反应)。2)实验性痛:①痛感觉:两例患儿均无;②“痛”反应:例1有“痛”反应(脉搏和呼吸的变化以及行为反应明显,大致与正常儿童相似)。例2无“痛”反应(脉搏和呼吸的变化轻微,无行为反应,与正常儿童不同)。 由结果看来,先天性无痛症患者似乎可分为两种类型:不完全型(如同例1)和完全型(如同例2)。存在有“痛”反应而无痛感觉的无痛症患者。 本工作结果从另一侧面为痛的两成分学说提供了依据。     

中-英双语读者词汇表征的研究(一)

以40个中文词和20个非词以及相应的英文译词为材料,以词汇判断中的重复效应为研究途径,对32名外语系本科生进行了中—英双语读者词汇表征的研究。结果发现,当单词以相同的语言重复呈现时(在语言内重复条件下),被试对重复词的判断时间显著缩短,判断准确性显著提高。而当单词以不同的语言重复呈现时(在语言间重复条件下),对重复词的反应时间与错误率与对新词的反应相比无显著差异。我们得到的语言内的重复效应与独立存储的假设相一致。我们认为,中—英双语读者对来自两种语言的词汇信息是分别存储在两个独立的言语存储系统中的。     

Training Mental Health Professionals to Assess and Manage Suicidal Behavior: Can Provider Confidence and Practice Behaviors be Altered?

Remarkably little systematic research has studied the effects of clinical suicidology training on changing practitioner attitudes and behaviors. In the current study we investigated whether training in an empirically‐based assessment and treatment approach to suicidal patients administered through a continuing education workshop could meaningfully impact professional practices, clinic policy, clinician confidence, and beliefs posttraining and 6 months later. At the 6 month follow‐up we found that 44% of practitioners reported increased confidence in assessing suicide risk, 54% reported increased confidence in managing suicidal patients, 83% reported changing suicide care practices, and 66% reported changing clinic policy. These results suggest that a brief and carefully developed workshop training experience can potentially change provider perceptions and behaviors with a possible impact on clinical care therein.
