Background: Prenatal alcohol exposure (PAE) is associated with growth deficits and neurodevelopmental impairment including foetal alcohol spectrum disorder (FASD). Difficulties with oral and written communication skills are common among children with PAE; however, less is known about how communication skills of adolescents who have PAE compare…

Sex differences in autism may in part be understood by an atypical sex profile of executive function and non-executive function. In this study, we compared females and males with autism against non-autistic individuals on neuropsychological and self-report measures to examine whether any sex differences in executive function and non-executive…

Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

Differentiating between early-onset bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) can be difficult. Memory problems are commonly reported in BD, and forgetfulness is among the diagnostic criteria for ADHD. We compared children and adolescents with BD (n = 23), ADHD combined type (ADHD-C; n = 26), BD + ADHD-C (n = 15),…

The authors of this current study compared the memory performance of adolescent students with specific reading disabilities (RD) with that of typical adolescent readers on a newly developed verbal learning test, the "Bergen-Tucson Verbal Learning Test" (BTVLT). This multiple trial test was designed to measure memory acquisition,…

Under certain experimental conditions, it was affirmed more quickly that a word belonged to a large category than to a small one. This, in conjunction with other experiment results, contradicts predictions of previous theories of word meaning and supports a feature selection theory derived from Garner's critical realism position.

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

An adaptive network model is proposed to represent the structure and processing of knowledge. Accessibility of subjects' stored information was measured. Relationships exist among (a) frequency of verifying a test relation, (b) other relations involving concepts used to evaluate test relation, (c) frequency of verifying those relations. (CHK)

Three experiments investigated the hypothesis that, when interpreted in context, general terms are typically encoded on the basis of an instantiation. Results indicated that a particular term naming the expected instantiation of a general term was a better cue for recall of a sentence than the general term itself. (CHK)

Two aspects of memory for prose were investigated. The amount of information remembered and the semantic interpretation assigned to ambiguous paragraphs. Task instructions and exposure duration of passages were varied. Recall and recognition measures indicated students remembered more with instructions requiring processing at a semantic level.…

This study tested predictions from Clark and Haviland's formalization of what people do when integrating information. Subjects were presented with simple sentences issued from a set of complex ideas, and asked to reconstruct the complete ideas. Results support predictions based on a recoding strategy formalized by Clark and Haviland. (CHK)

A theory for representation of concepts in memory is proposed which emphasizes the association of salient exemplars with the concept. Previous theories dealing with the classification processes involved in acquiring new concepts have shown that clear category boundaries do not exist. It is proposed that present theory must account for the…

To show the organization of recall, items that are remembered together can be written on the same line of a two-dimensional (2D) grid. Such 2D recall does not induce the clustering it reveals. Various aspects of 2D recall and the clustering it reveals are discussed. (Author/RM)
