Recent research has suggested that outcome feedback is not the optimal form of feedback for learning complex interference tasks. The present experiment was designed to test the effects of outcome feedback against cognitively oriented feedback in a number of linear tasks. (Editor)

This study examined the hypothesis of superior quantification abilities of persons with high functioning autism (HFA). Fourteen HFA individuals (mean age: 15 years) individually matched with 14 typically developing (TD) participants (gender, chronological age, full-scale IQ) were asked to quantify as accurately and quickly as possible…

Inflated perceptions of responsibility are hypothesized to contribute to compulsive checking. Reassurance seeking, proposed to be a form of checking, may exacerbate checking behaviour in the long run. A sample of non-clinical participants (N = 100) performed a complex manual classification task under 1 of 4 experimental conditions: high…

Applying Bloch's law to visual word recognition research, both exposure duration of the prime and its luminance determine the prime's overall energy, and consequently determine the size of the priming effect. Nevertheless, experimenters using fast-priming paradigms traditionally focus only on the SOA between prime and target to reflect the…

Confidence intervals are beginning to play an increasing role in the reporting of research findings within the social and behavioral sciences and, consequently, are becoming more prevalent in beginning classes in statistics and research methods. Confidence intervals are an attractive means of conveying experimental results, as they contain a…

A Bayesian statistical procedure separating storage from retrieval was used to study development and release of proactive interference in the Brown-Peterson paradigm. A theory of PI is developed stressing response competition at test time and interference in transfer between short- and long-term memory. (CHK)

Using B.F. Skinner's diagnosis of our moral problems, this research attempts to provide a constructive supplement to Kohlberg's moral theory rather than to concentrate on negative criticism. Examines the cognitive and affective aspects of Kohlberg's morality. (Author/RK)

The objective assessment of thought disorder in schizophrenia is problematic in clinical psychology. Recently, an individually administered instrument (WIST) was introduced as a brief, objective, and quantitative measure of schizophrenic thought processes. Possible shortcomings of the WIST are noted; experimental findings that concern extension to…

Tested the hypothesis that cognitively complex judges will be more attracted to similar others than to dissimilar others, while cognitively simple judges will not be differentially attracted to similar and dissimilar others. (Author/RK)

After developing the theory that writing is enhanced when the writer discusses his ideas before he submits them to paper, author outlines an experiment to test the theory. (Editor)

Causes of evaluator bias are: overemphasizing concrete, salient, and retrievable information; reporting only evidence which confirms hypothesis; focusing on stable personality factors, rather than on situation and environment; developing positive perceptions of a program as both an evaluator and a highly involved participant; statistical naivete;…

The minimalist hypothesis of inference processing is proposed. According to this hypothesis, the only inferences coded automatically during reading are those based on easily available information and those required to make statements in a text locally coherent. Five experiments with 249 college students support the hypothesis. (SLD)
