Alleviation of forgetting of discrimination learning

Reactivation treatments intended to alleviate forgetting in rats were tested in two discrimination tasks—instrumental learning with brightness or with spatial location as the discriminanda. For memories acquired 28 days earlier, forgetting was alleviated with both tasks when testing was preceded by certain reactivation treatments. Therefore, the generality of the effectiveness of reactivation treatments for alleviating forgetting is extended to include discrimination learning and response measures other than go, no-go behavior.     

Adaptation effect in nonfluent speech behavior of controlled stutterers and nonstutterers

The adaptation effect in stuttering behavior has received considerable attention. Adaptation effect is defined as the reduction in the frequency of nonfluencies in the speech of subjects during successive readings of the same passage. The objective of this investigation was to assess the adaptation effect of nonfluent speech behavior of controlled stutterers and nonstutterers. The subjects included 35 controlled stutterers and 35 nonstutterers matched for factors of sex, grade level, and age. Results suggest a significant mean difference between the number of nonfluencies between trials of controlled stutterers with evidence of adaptation in the speech of nonstutterers. Nonstutterers demonstrate significant mean differences in nonfluencies among replicated testing occasions. Findings of this investigation suggest that both controlled stutterers and nonstutterers demonstrate similar adaptation regarding their nonfluent speech behavior. Issues and import for future research are offered.     

Metacognition,Metalanguage and Metapragmatics

In this article, the author briefly reports John Flavell's analysis of metacognition. By attempting to integrate metalinguistic activities into this analysis, the author brings to light several interesting characteristics of the field of metalinguistics and its current state of research. Firstly, it appears that, unlike other meta-abilities, the metalinguistic abilities are defined in terms of their objects. On this basis, metalinguistic activities are at least partially independent of other metacognitive activities. Secondly, it appears that the position of metapragmatics in relation to metalinguistics is in need of greater clarification. In particular, it seems necessary to draw a distinction between metapragmatic knowledge and metapragmatic experience. The fact that this distinction is not usually made contributes to the heterogeneity of this field of study and gives rise to fruitless controversy. Finally, the analysis reveals that the manipulation of writing mobilises aspects of metalinguistic knowledge which are not mobilised spontaneously through speech. The study of where this knowledge is positioned and of the cognitive burden its manipulation represents at various levels of reading and writing ability has yet to be developed.     

Phonological deficits: Beneath the surface of reading-acquisition problems

Summary In Experiment 1, the performance of young retarded readers on speech-segmentation tasks was compared with the performance of normal subjects matched for chronological age (CA) and with subjects matched for reading age (RA). Retarded readers were poorer than both control groups in consonant deletion, while there was no difference between the groups on a rhyme-judgement task and a syllabic-vowel-reproduction task. In Experiment 2, another group of reading retarded children was compared with CA and RA controls on the classification of pseudowords, either by common phoneme or by overall phonetic similarity. The retarded readers made fewer classifications based on common phoneme than both control groups, while there was no difference between the groups in classifications based on overall phonetic similarity. In Experiment 3, adult developmental dyslexics were compared with normal adults in the tasks of Experiments 1 and 2. The dyslexics made fewer classifications based on a common phoneme than the normals, while no difference was found in classifications based on overall phonetic similarity.     

Program report: “time-in”: A two-year project for the reduction of severe maladaptive behaviors in a center for persons with developmental disabilities

The results of a two-year project designed to organize a unit for 18 developmentally disabled clients with severe behavior disorders (primarily aggression) were presented. Providing tightly organized structure and focusing on appropriate resident behavior resulted in substantial gains. Noted changes included significant decreases in aggression, total number of target behaviors, required uses of restrictive procedures, and residents' injuries. Decreases were also noted in staff injuries and turnover. Subjectively, the unit became a better place to work and live. Difficulties encountered with developing, maintaining, and generalizing the project were discussed.     

A generation effect with numbers rather than words

Memory &; Cognition - It has previously been shown that a word from a list is more likely to be remembered if the word was generated, rather than read, by the subject. Two simple experiments...
