Decisions about whether pairs of letter strings are both words or not are faster for semantically related words than unrelated words. Two experiments showed the semantic relatedness effect is greatly reduced when orthographically illegal, unpronounceable strings were used as negative items. Lexical decisions involve options on codes representing…

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)

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)

Presents a "procedural view" of the learning mind, arguing against previous theories citing physical properties as its basis. A more process-oriented view of information processing is offered, which describes "mind" in terms of skill in manipulating symbols, and the notion of skills is shown to provide a useful framework for accounting for…

A model is proposed in which information processing is accompanied by dynamic processes, including the reorganization of items into active patterns and their subsequent displacement. Research using category names and instances showed that reaction times decreased with each successive repetition under one condition, but longer latencies were…

Trace strength was examined as a function of single and spaced-multiple encodings within and across the orthographic, acoustic, and semantic domains. Recall results revealed that multiple encodings yielded additive or greater than additive retention effects while the recognition accuracy results revealed additive or less than additive effects.…

Examines the inhibition of recall of list items when extralist items are introduced, and describes experiments which suggest that this is an expression of a more general inhibition phenomenon. (Author/AM)

Reports on two experiments which question the assumption that semantic processing is superior to nonsemantic processing, and which demonstrate that effective semantic elaboration cannot be equated with the quantity of semantically congrous information. (Author/AM)

The Bransford and Franks paradigm for the study of semantic integration is called into question. Three experiments are described that test the hypothesis that this paradigm produces its results by creating confusion and interference. The results call for continued search for a paradigm relative to the study of integration. (AMH)

Experiment I studied type of processing (semantic or nonsemantic) and dimension of rating (pleasantness or frequency of occurrence). Recall was higher under semantic conditions and after ratings of pleasantness. Experiment 2 showed that the difference between incidental and intentional learners increases as more stress is placed on the learning…

Levels of processing were manipulated as a function of acquisition task and type of recognition test in three experiments. Experiment I showed semantic acquisition to be superior to rhyme acquisition given a standard recognition test, whereas rhyme acquisition was superior given a rhyming recognition test. Results are interpreted and discussed.…

Three experiments are reported in which, following presentation of a categorized list, subjects either recalled the whole list or a part of the list. Results indicate that it is difficult to retrieve selectively parts of a studied list when instructions specify only what not to recall. (Author/AM)
