The Laboratory Course in Psychology: I. Methods Employed for Ranking Stimuli

Dietary requirements of Southern Plains wood rats ih'cotoma micropus nticropus, Baird) were studied by Richter's self-selection of diet method. Nine of 16 adult wood rats fed an array of four purified or semipurified foodstuffs plus water slowly adjusted to the dietary arrangement and thrived thereafter. The other wood rats exhibited nonspecific rejection for all items until death. Subsequently, foodstuffs from the array were mixed in quantities proportional to the mean daily intake of each by the successful selectors during the final portion of the self-selection period. Successful selectors and an equal number of experimentally naive wood rats were fed the mash for nine weeks. Neither group differed significantly in weight at the end of the period from a control group fed a commercial chow     

2007-2010年心理学专业基础综合考试的多元概化理论研究

摘 要 本研究使用多元概化理论分析2007-2010年心理学专业基础综合考试。结果表明：1.从考查的学科内容看,心理统计与测量、普通心理学的测量精度较高,而发展与教育心理学、实验心理学的测量精度偏低;2.从设置的题型看,多选题的测量精度偏低,其他题型的测量精度较高;减少单选题数量、增加多选题数量可在保障全卷测量精度的基础上大幅提高多选题的测量精度;3.全卷测量精度很高,不同年度的试卷在学科内容和题型结构上可看成是“平行”试卷。     

考试评分缺失数据的概化理论分析

考试评分缺失数据较为常见,如何有效利用现有数据进行统计分析是个关键性问题。在考试评分中,题目与评分者对试卷得分的影响不容忽视。根据概化理论原理,按考试评分规则推导出含有缺失数据双侧面交叉设计（p×i×r）方差分量估计公式,用Matlab7.0软件模拟多组缺失数据,验证此公式的有效性。结果发现：（1）推导出的公式较为可靠,估计缺失数据的方差分量偏差相对较小,即便数据缺失率达到50％以上,公式仍能对方差分量进行较为准确地估计;（2）题目数量对概化理论缺失数据方差分量的估计影响最大,评分者次之,当题目和评价者数量分别为6和5时,公式能够趋于稳定地估计;（3）学生数量对各方差分量的估计影响较小,无论是小规模考试还是大规模考试,概化理论估计缺失数据的多个方差分量结果相差不大。     

大学生感恩内隐效应的实验研究

研究探讨内隐联想测验(Implicit Association Test,IAT)和Go/No-go联想任务测验(Go/No-go Association Task, GNAT)测量大学生感恩的可行性,并分析内隐感恩与外显感恩的关系。预备性研究从现代汉语字典中挑选自我词/他人词各16个,从汉语成语大辞典中挑选出与感恩相关的积极词/消极词各20个,根据65位大学生的评定结果筛选出自我词/他人词各8个,积极词/消极词各8个,用于正式研究。正式研究采用IAT、GNAT感恩测量程序和青少年感恩量表(Adolescent Gratitude Scale,AGS),对155名大学生同时进行IAT、GNAT及外显感恩的测量。结果发现:(1)大学生普遍具有积极的内隐感恩,内隐感恩不存在性别、生源地和独生与否等人口统计学指标上的显著差异;(2)大学生的内隐感恩与外显感恩相关不显著,是两个不同的建构;(3)采用IAT和GNAT研究感恩是可行的。     

On the historical and conceptual background of the Wisconsin Card Sorting Test

In this paper, we describe the development of the Wisconsin Card Sorting Test (WCST). We trace the history of sorting tasks from the studies of Narziss Ach on the psychology of thinking, via the work of Kurt Goldstein and Adhémar Gelb on brain lesioned patients around 1920 and subsequent developments, up to the actual design of the WCST by Harry Harlow, David Grant, and their student Esther Berg. The WCST thus seems to originate from the psychology of thinking ('Denkpsychologie'), but the test, as it is used in clinical neuropsychological practice, was designed by experimenters working within the behaviorist tradition. We also note recent developments suggesting that, contrary to the general impression, implicit learning may play a role in WCST-like discrimination learning tasks.     

Validity of a happiness Implicit Association Test as a measure of subjective well-being

The current study examined the validity of a happiness Implicit Association Test (IAT) as a measure of SWB. One hundred and fifty participants (75 pairs of friends) completed a newly developed happiness IAT and a standard self-esteem IAT. Participants also made self and informant ratings of life satisfaction and happy and sad affect. The results revealed convergent validity among the explicit measures, and among the implicit measures. Explicit–implicit correlations were lower. Self-ratings (.88) and informant ratings (.78) were more highly related with a common SWB factor than the implicit measures (.31). This finding suggests that implicit measures of well-being and happiness assess a different construct that overlaps only modestly with SWB. As a result, these implicit measures have limited utility to control for response styles in self-ratings of SWB.     

Utilisation des intervalles de confiance au lieu des tests de signification : aspects épistémologiques et pratiques

The use of confidence intervals instead of significance tests is strongly recommended by the fifth edition of the manual of the American Psychological Association (2001). This possibility as well as other improvements in statistical practice are discussed in the framework of the major theoretical options subtending statistical inference and the way they have been applied in psychology for about 50 years. First, the suggestion of a complete ban on statistical testing is examined and rejected. Next, a procedure consisting in measuring the fit of two competing models based on the likelihood ratio is judged interesting and commendable. Finally, the superiority of an approach based on confidence intervals instead of significance tests is assessed and illustrated by its application to an experimental study aiming to demonstrate the absence instead of the presence of an effect of the independent variable.     

Are ants sensitive to the geometry of tunnel bifurcation?

The ability to orient and navigate in space is essential for all animals whose home range is organized around a central point. Because of their small home range compared to vertebrates, central place foraging insects such as ants have for a long time provided a choice model for the study of orientation mechanisms. In many ant species, the movement of individuals on their colony home range is achieved essentially collectively, on the chemical trails laid down by their nest mates. In the initial stage of food recruitment, these trails can cross each other and thus form a network of interconnected paths in which ants have to orient. Previous simulation studies have shown that ants can find the shortest path between their nest and a food source in such a network only if there is a bias in the branch they choose when they reach an asymmetrical bifurcation. In this paper, we studied the choice of ants when facing either a symmetrical or an asymmetrical bifurcation between two tunnels. Ants were tested either on their way to a food source or when coming back to their nest, and either in the presence or in the absence of a chemical trail. Overall, our results show that the choice of an ant at a tunnel bifurcation depends more on the presence/absence of a trail pheromone than on the geometry of the bifurcation itself.

Human Cognition in Context: On the Biologic,Cognitive and Social Reconsideration of Meaning as Making Sense of Action

The aim of this special issue of IPBS has been to explore concrete and explicit alternatives to cognitivism. Indeed, in our editorial introduction we set out to give a brief survey of the numerous criticisms that have been made of understanding the mind this way (Ibáñez and Cosmelli, Integrative Psychological and Behavioral Sciences, 2008). Thus in what sense do the contributions here presented succeed in providing novel alternatives, moving into original and potentially generative domains of inquiry? While much remains to be done, we believe that they make significant headway in more than one sense. We do believe, however, that there is one locus that furnishes a convergence ground that is worth considering seriously: the problem of meaning. Meaning as making sense of contextualized action seems to cross the domains of intentionality, intersubjectivity and ecology of mind. The development of multilevel approaches, as the authors here exemplify, argues for a novel research agenda.
