Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

Purpose: The aim of this study was to determine whether the word-learning challenges associated with developmental language disorder (DLD) result from encoding or retention deficits. Method In Study 1, 59 postsecondary students with DLD and 60 with normal development (ND) took the California Verbal Learning Test-Second Edition, Adult Version…

The ability to adapt behavior in a changing environment is necessary for humans to achieve their goals and can be measured in the lab with tests of rule-based switching. Disease models, such as cocaine addiction, have revealed that alterations in dopamine interfere with adaptive set switching, culminating in perseveration. We explore perseverative…

Retroactive interference (RI) in list learning occurs when the learning of a second list of words interferes with the recall of the first learned list. Having the lists be thematically different can reduce retroactive interference within list learning; however, this study demonstrates how RI can be reduced when the lists contain similar words.…

This study investigated the verbal and visuospatial processing and storage skills of children with SLI and typically developing children. Fourteen school-age children with SLI, and two groups of typically developing children matched either for age or language abilities, completed measures of processing speed and storage capacity, and a set of…

Despite the importance of good lecture notes to test performance, very little is known about the cognitive processes that underlie effective lecture note taking. The primary purpose of the 2 studies reported (a pilot study and Study 1) was to investigate 3 processes hypothesized to be significantly related to quality of notes: transcription…

Subjects memorized subject-verb-object propositions and then judged whether verb-object probes appeared in the same proposition. Reaction times and error rates were observed. Data indicate that activation spreads from probe concepts in parallel through the propositional network. A guessing model for errors was constructed. (CHK)

Experiments are described in which students listened to messages describing the placements of numbers in imaginable matrices. Recall was tested by having students write in the correct cells of a blank matrix. Results appear consistent with a modified level of processing approach. (Author/RM)

The effect of presupposition on memory depends upon a restricted class of pragmatic conditions. If certain intended misleaders are introduced, presupposition does not enter into memory. This was shown with two experiments in which subjects "remembered" an accident differently, depending upon whether misleading facts were introduced.…

This study explored the extent and accuracy of the subject's knowledge of his previous recall performance as a function of response mode and response-produced feedback. In free recall trials, subjects responded orally, in writing, or in both oral and written modes. Accuracy of later recall or responses was measured. (CHK)

This study examined conceptual relationships in semantic memory using an indirect priming technique in high-functioning autistic adolescents and controls. The autistic subjects and controls showed similar semantic priming effects. However, correlations with nonverbal cognitive measures for the autistic subjects suggests that semantic processing in…

This paper evaluates associative theories of sentence memory, based on the model of J.R. Anderson and G.H. Bower. A model of Human Associative Memory (HAM) is generalized and defined, and alternative models incorporating configural information are presented. (CK)

This study investigated the role of semantic variables, derivable from multidimensional scaling, in search and decision processes. (Author/RM)

Explores the extent and accuracy of the subject's knowledge concerning his previous memory performance. (Author/RM)

It was hypothesized that Ss hearing sentences containing reported utterances would confuse these sentences with new sentences containing illocutionary forces or perlocutionary effects consistent with the original sentences. Predicted effects were found in recall for illocutionary forces and in recognition memory for perlocutionary effects.…
