This summary of research performed during the past five and one-half years and dealing with different attributes in memory functioning is organized around four attributes of memory: "Frequency Attribute: Verbal Discrimination" explores the development of the theory dealing with verbal discrimination tasks and lists several papers prepared during…

The results of this study suggest that mnemonics may have little or no direct effect upon retention, although they profoundly influence the rate of original learning. Based upon a dissertation submitted in partial fulfilment of the requirements for the PhD., University of California, Berkeley, 1968. (Author/FWB)

This study examines the effects on long-term retention of variations in intensity and temporal parameters of arousal following a single learning trial in a paired-associate task. Intensity of arousal was manipulated by using two levels of noise, 75 db. and 90 db., and a condition without noise. Noise was delivered to the 56 female university…

To investigate organizational strategies of educable mentally retarded (EMR) and normal boys, the performance of 30 normal boys (mean IQ 105.1) and 30 EMR boys (mean IQ 69.9), ages 7-12 years, was compared on various free recall learning tasks. Three measures of input organization employed were category clustering, associative clustering, and…

In two separate paired-associate learning experiments each employing 40 university students as subjects, the contribution of individual differences (IDs) in arousal to short- and long-term retention was investigated using IDs in salivary response to lemon juice stimulation as an index of arousal. Experimental subjects were pre-selected out of 184…

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…

Rote learning and retention performance was studied as a function of method used in original learning and as a function of intellectual level. Sixty educable mentally retarded and 60 mentally normal junior high school students were randomly selected and assigned to one of three treatment groups, each learning to a different criterion, for each…

Paired-associate learning efficiency was assessed within four low-SES ethnic populations (black, Chinese-American, Latino-American, and white) as a function of presentation conditions and method of measurement (verbal recall vs. pictorial recognition). A mixed-list paired-associate task was administered individually to 40 second grade children…

Eight experiments studied the following aspects of associative strategies in learning: classification; verbalization at three developmental levels; verbalization by normal and educable children; facilitation of associative learning among educable retardates; effectiveness of familiarization and differentiation training on the successful employment…

Three experiments tested whether qualitative differences in processing of verbal materials result from congenital hearing impairment. Subjects were children with reading levels equivalent to grades 4 to 6. Experiment 1 used repeated measurements with two modes of response and two kinds of cues; experiment 2 used acoustic similarity to produce…
