The effect of a classification, or encoding, task on intentional free recall was examined. Examination of the serial position curves for immediate and free recall shows clear effects assigned to long-term store. Consideration of effects regarding levels of processing gives a parallel account differing only in terminology and emphasis. (CHK)

Previous research has shown that concrete concepts are more readily attained than abstract concepts. In the present study this dominance effect was confirmed for verbal materials, even when instances and concepts were equivalent in instance frequency, meaningfulness and conjoint frequency. This effect was especially marked under high memory-load…

Performance changes during the course of single-trial free recall were investigated in five experiments. (Author/RM)

Many theories of memory assume memory representations are abstract and exclude specific lexical information. Results of three experiments in this study suggest lexical information is present and persists in memory representations of meaning. A word-based theory of memory should be preferred over available theoretical alternatives. (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)

Meyer found subjects were faster to determine if a stimulus word was a member of either of two prespecified categories if the categories were close in meaning. A reanalysis of the data favors instead a model emphasizing the role of decision-making processes in categorization and flexibility of task strategies. (CHK)

Three experiments are reported regarding reaction time. Letter comparison time was found to increase when other irrelevant letters were present, regardless of whether or not the letters made up a word or a word-like configuration. Word comparison time was found to increase when distractors were similar to targets. (Author/RM)

Subjects were asked to encode and recall lists of words under the influences of marijuana and a marijuana placebo. Free recall was more complete when both encoding and recall were after marijuana use than in the encode-marijuana, recall-placebo state. Recall must depend on restoration of dissociated encoding state. (CHK)

The guessing-bias and proactive interference hypotheses of the Ranschburg Effect were investigated by giving three groups different instructions as to guessing during recall. Results failed to support the prediction that the effect should be reduced or eliminated on shift trials. Neither hypothesis received significant support. (CHK)

The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

Four experiments are reported in which relations of semantic distance to response latencies in similarity judgments, to reaction times in a same-different classification task, and to proximity of recall in a free recall task were investigated. (Author/RM)

Two experiments are described. One measured performance of subjects on pairs of concurrent verbal tasks, monitoring sentences for certain items while reading. Secondary task performance combined with a primary task is proportional to its performance in isolation. The second experiment checked certain results of the first. (CHK)
