In two experiments, a probe technique required subjects to respond when the digit 7 appeared in one of five-letter positions in words or nonwords, inserted at the onset and 500 msec after letter and word processing. The focus of attention given to a letter has a smaller spatial extent. (Author/CM)

Three experiments tested contrasting predictions of a dual-representation theory and a context availability model of concreteness effects in verbal processing. Without context, reading times/lexical decision times for abstract sentences/words were longer than for concrete sentences/words. Rated context availability was a good predictor of reaction…

In four experiments, college students were presented with lists of either Armenian or English letters on a tachistoscope. The data indicate that extensive practice may be a necessary condition for capacity-free processing but may not be a necessary condition for involuntary processing. (Author/RD)

That additional exposure to memorial material improves subsequent retrieval probabilities was explored. The effect of a recognition test on subsequent recall and recognition of categorized lists was studied. Prior recognition tests increased recall of original items, but also increased intrusions. Similarly, prior exposure increased hit rates and…

Reaction time and accuracy do not always reflect the same perceptual processes; therefore, the convergence of reaction time with accuracy within the context of a specific information processing model should be demonstrated empirically rather than assumed a priori. (Author/PN)

The results demonstrate a use of semantic information to circumvent an item-by-item search of memory. Similar results have been obtained in the fact-retrieval paradigm of long-term memory. (PN)

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)

Adults' geometric analogy solution was investigated as a function of systematic variations in the information structure of items. Latency data from verification of true and false items were recorded. A model incorporating assumptions about the form of item representation, working memory factors, and processing components and strategies was…

Results of a study indicated that, as age increased from seven to 20 years, reaction time decreased, with males having a more rapid reaction time than females. Beginning at age 10 or 11, subjects developed better motor plans and relied less on rapid reaction time to achieve good anticipation time. (FG)

Reports on three experiments designed to determine when inferential elaborations dealing with instruments and consequences of action were made--at comprehension or retrieval. (HOD)

Seven- and eight-year-olds, representing a wide range of locus of control scores, practiced one of three self-verbalization treatments of behavioral rule learning: overt speech, covert speech, or a combination of both. Latency scores in the toy temptation test were highest for the combination treatment group. (SJL)

Explored the relationship among conceptual tempo, age, sex, and performance of preschool children on the visual association subtest of the Illinois Test of Psycholinguistic Abilities. (Author/DB)

Following trials in which children self-administered prizes, subjects in the stringent-demand group performed significantly better, during both the incentive and the extinction conditions, on time at task, number of correct problems, and number of problems attempted, than did subjects in lenient-demand and control groups.
