Effects of within-class differences in sample responding on acquired sample equivalence

Two experiments examined whether acquired sample equivalence in many-toone matching was affected by variation in sample-response requirements. In each experiment, pigeons responded on either identical or different response schedules to the sample stimuli that occasioned the same reinforced comparison choice (i.e., to the within-class samples). Transfer-of-control tests were then conducted to determine acquired equivalence, or lack thereof, between these samples. In both experiments, there was minimal or no evidence of acquired sample equivalence when pigeons responded differently to the samples within each common-choice class. By contrast, transfer was observed if pigeons responded (a) identically to all sample stimuli, or (b) identically to samples within each common-choice class (viz., to samples that occasioned the same reinforced choice) and differently to samples from different classes (viz., to samples that occasioned different choices). These results may help to explain the recent lack of evidence for response membership in pigeons' acquired equivalence (Urcuioli, Lionello-DeNolf, Michalek, & Vasconcelos, 2006). They also raise questions about the functional sample stimuli and about possible interactions between acquired equivalence and acquired distinctiveness.     

Regularized Multiple-Set Canonical Correlation Analysis

Multiple-set canonical correlation analysis (Generalized CANO or GCANO for short) is an important technique because it subsumes a number of interesting multivariate data analysis techniques as special cases. More recently, it has also been recognized as an important technique for integrating information from multiple sources. In this paper, we present a simple regularization technique for GCANO and demonstrate its usefulness. Regularization is deemed important as a way of supplementing insufficient data by prior knowledge, and/or of incorporating certain desirable properties in the estimates of parameters in the model. Implications of regularized GCANO for multiple correspondence analysis are also discussed. Examples are given to illustrate the use of the proposed technique. The work reported in this paper is supported by Grants 10630 and 290439 from the Natural Sciences and Engineering Research Council of Canada to the first and the second authors, respectively. The authors would like to thank the two editors (old and new), the associate editor, and four anonymous reviewers for their insightful comments on earlier versions of this paper.

What's Wrong with Creativity Testing?

Creativity testing as it is now done is often based on a defective assumption that different kinds of creativity can be compressed into a single unidimensional scale. There is no reason to believe that the different kinds of creativity represent, simply, different amounts of a single unidimensional construct. The article shows how three different ways of viewing creativity lead to different ways of measuring creativity, all at variance with current unidimensional models. The point of view presented here does not suggest that current creativity tests are invalid, but rather, that care must be taken in the nature of claims made for them. Moreover, many of the same arguments could be applied to the measurement of intelligence and even wisdom as well.

决策与判断研究中的个体分析(英文)

决策与判断研究中(甚至是实验心理学研究中)的许多问题关注某效应是否真实存在,及其背后的解释是什么。这些问题不关注该效应在某一特殊群体中是否显著。因此,可以通过分析单个被试来检验效应的显著性。如果有一个被试表现出了该效应,那么,这个效应就是存在的。根据这一观点,有时也可通过跨案例或者轮次(across cases or rounds)分析来验证效应的显著性,而不需要进行跨被试分析(across subjects)。这一观点也暗示在一些实验中可能存在反方向的效应。本文建议通过进行基于被试个体的统计分析来检验这样的效应,并介绍了一些不同形式的方法:PP概率图(probability probability plots);P值分布检验(tests of the distribution of p-values);分层取样多重检验的矫正(correction for multiple testing with step-down resampling)。这些方法都可以用于处理在对同样假设进行多重检验时无法避免的问题。另外,本文也列举了一些例子,其中有一部分例子存在反方向的效应,另一部分例子不存在。     

Associative symmetry by pigeons after few-exemplar training

The present experiment investigated whether pigeons can show associative symmetry on a two-alternative matching-to-sample procedure. The procedure consisted of a within-subject sequence of training and testing with reinforcement, and it provided (a) exemplars of symmetrical responding, and (b) all prerequisite discriminations among test samples and comparisons. After pigeons had learned two arbitrary-matching tasks (A-B and C-D), they were given a reinforced symmetry test for half of the baseline relations (B1-A1 and D1-C1). To control for the effects of reinforcement during testing, two novel, nonsymmetrical responses were concurrently reinforced using the other baseline stimuli (D2-A2 and B2-C2). Pigeons matched at chance on both types of relations, thus indicating no evidence for symmetry. These symmetrical and nonsymmetrical relations were then directly trained in order to provide exemplars of symmetry and all prerequisite discriminations for a second test. The symmetrical test relations were now B2-A2 and D2-C2 and the nonsymmetrical relations were D1-A1 and B1-C1. On this test, 1 pigeon showed clear evidence of symmetry, 2 pigeons showed weak evidence, and 1 pigeon showed no evidence. The previous training of all prerequisite discriminations among stimuli, and the within-subject control for testing with reinforcement seem to have set favorable conditions for the emergence of symmetry in nonhumans. However, the variability across subjects shows that methodological variables still remain to be controlled.     

Computerized Cognitive Tests (CCT) in elderly: A psychometric review

Introduction/aim

Computerized Cognitive Tests (CCT) play an increasing role in the assessment of elderly cognitive impairment. In this framework, it is important to review the psychometric data of the available CCT in the detection of cognitive decline.

Transgenerational patterns of abusive parenting: Analog and clinical tests

Two studies were conducted to determine whether there was an association between punitive childhood histories and abusive parenting. In the first experiment, undergraduate students who reported more punitive childhood histories and undergraduates who reported mild or nonpunishing childhoods were tested with an Analog Parenting Task. The task used photographic stimuli to depict child behaviors and to elicit disciplinary choices in response to children's transgressions. Persons from the more punitive backgrounds were significantly more likely to endorse potentially injurious disciplinary responses. Additionally, in a post-hoc analysis, women with mild punishment backgrounds were more likely to indicate they were annoyed by the depicted child behaviors than women with the severe punishment backgrounds and men with both punishment histories. In the second experiment, childhood histories of parents of children seen at a psychiatric clinic were assessed. The data indicated an association between severely punitive backgrounds of parents and the probability that the referred child had been physically abused. Also, the punishment histories of the parents were associated with the presence of antisocial and aggressive presenting problems displayed by the referred child. The two experiments together were considered to provide support for a modified version of the trans-generational hypothesis of abuse.     

Ecological validity of neuropsychological assessment: Do neuropsychological indexes predict performance in everyday activities?

This paper discusses the nature of neuropsychological assessment within the context of ecological validity. It considers the extent to which traditional neuropychological tests can predict performance in everyday life before going on to describe several new procedures designed to map directly on to real life functioning.
