Explored the relative effectiveness of four modes of delivery (live, video-audio, audio, and manuscript) on content retention among Black college students. Did not find significant differences in retention among the four experimental groups. Attributes the absence of differences to the small amount retained in general. (GC)

Reports three experiments investigating the relationship of the suffix effect and echoic memory. Shows that echoic memory persists for at least 20 seconds. Illustrates that echoic memory can be used to establish a more effective nonechoic memory. Shows that recency recall is higher to auditory than to visual items. (PMJ)

Undergraduate students using an imagery mnemonic mediating technique involving "keywords" to learn definitions of thirty unfamiliar words performed better on a 1-week delayed comprehension test, on at least half of the definitions, than those who read and copied definitions. Mnemonic mediating strategies worked better than nonmediating strategies…

THIS STUDY WAS CONDUCTED DURING 1966 TO DETERMINE THE EFFECTS OF MAGNESIUM PEMOLINE (A COMBINATION OF 2-IMINO-5-PHENYL-4-OXAZOLIDINONE AND MAGNESIUM HYDROXIDE) ON A VARIETY OF HUMAN LEARNING, MEMORY, AND PERFORMANCE TASKS. MAGNESIUM PEMOLINE (25 OR 37.5 MG) OR A PLACEBO WAS ADMINISTERED ORALLY ON A DOUBLE-BLIND BASIS TO INTELLIGENCE-MATCHED GROUPS…

The purpose of this study was threefold: to determine whether adding a mnemonic to systematically designed instruction would improve verbal retention, to establish whether retention is better for concrete or abstract information, and to determine whether mental imagery or verbal elaboration is more effective for learning concrete or abstract…

From a total enrollment of 440 students in business communication classes, 270 voluntarily participated in a study of the relationship between the placement of performance objectives and reading comprehension. Students were tested for reading comprehension and were randomly assigned to one of two experiments and to pre-, post-, or no-objective…

A study was made to determine how the rate of spelling and the retention of spelling words was influenced by the number and spacing of practice presentations on unlearned words. Sixth-grade students (42) in East Palo Alto were drilled by a computer for 6 weeks on six lists of 12 different spelling words each. They drilled on one list until (1)…

Reviews recent experimental and theoretical analyses of the relationship between level of processing and retention, and reports on two studies which tested predictions about the effects of orienting activities on retention. (AM)

In experiments where hypnotized subjects learned one word list while happy or sad, retention proved to be surprisingly independent of the congruence of learning and testing moods. Learning mood provided a helpful retrieval cue and differentiating context only where subjects learned two word lists, one while happy, one while sad. (EJS)

Recent research in the area of prose comprehension is reviewed, including factors that affect amount of recall, representations of text structures, and use of world knowledge to aid comprehension. The need for more information processing models of comprehension is emphasized. Elaboration is considered important for comprehension and retention.…

Reports three experiments demonstrating that recall for words increases with deeper levels of processing and with longer rehearsal intervals. Asserts that there is no interaction between those strategies. (PMJ)

To obtain an a priori estimate of natural language mediators (NLM's) 320 pairs of words with the consonant-vowel-consonant-pattern (CVC's) were broken into four series of 90 pairs and presented to 240 male and female undergraduates. Pairs were shown for 15 seconds while the subjects wrote down any associative device or NLM they could generate that…

A compilation of 165 references dealing with short term memory, this bibliography supplements "Short-Term Memory: An Annotated Bibliography" (August 1968). The time period covered is predominantly June 1968 to June 1969. Such aspects and topics as psychometrics, motivation, human engineering, vision, auditory perception, verbal and nonverbal…
