Six experiments investigated loss of availability of surface form in sentence comprehension. Explanations for the loss included: (1) linguistic hypothesis; (2) memory limitations hypothesis; (3) integration hypothesis; and (4) processing shift hypothesis. (LMO)

Previous studies of the effect of age and modality on digit span task performance have yielded inconsistent results. To eliminate some of the methodological difficulties in prior research, 18 college students and 18 older adults were given the digit span task by means of three different modalities: (1) visual successive; (2) visual simultaneous;…

The auditory/verbal short-term memory of 64 college students was examined across a wide range of retention intervals (5 seconds to 60 seconds). High attention during interpolated processing was ensured by monitoring rehearsal with a combination of methods, and errors were analyzed for evidence of proactive and intra-unit interference. Recall of…

To determine whether different long-term memory representations are necessary for verbal and visual material, subjects studied faces composed of visual features or verbal facts composed of concepts. Findings showed interference between verbal and pictorial information, and supported the ACT theory that pictorial and verbal materials are stored…

Memory for sex of the speaker and language of presentation of a spoken message was high and reliably better when the features were instrumental for comprehending the message than when they were not. This suggests that the physical characteristics of an event may be deeply or elaborately encoded when they are meaningful in light of the task…

Thirty college undergraduates participated in a study of the effects of acoustic and visual interference on the recall of word and picture triads in both short-term and long-term memory. The subjects were presented 24 triads of monosyllabic nouns representing all of the possible combinations of presentation types: pictures, printed words, and…

Recent evidence suggests that whereas pictures are more easily recognized, discriminated, associated, and recalled than their corresponding verbal labels, this is not the case in concept acquisition/utilization tasks. If such evidence is interpreted in terms of a "frequency theory" perspective, one would expect the typically obtained…

The slower progress of semantic memory research is attributed to the difficulties involved in testing the relevant theories. This paper proposes a model for testing such theories using the Continuous Response (CR) task. The model establishes a link between the rate of recall and the semantic relationships among the category items. (JAZ)

A multirate mathematical model is presented to support the hypothesis that different types of information are lost from a memory trace at different rates. The model is validated by two experiments assessing the retention of pictures and of sentences at three different delays by cued recall. (Author/CP)

The effects of semantic (S), orthographic (O), and unrelated (U) verbal stimuli on word retrieval were examined. S stimuli inhibited locating items within categories, whereas U stimuli inhibited locating the appropriate category. The discrepancy between the present outcome and the previous finding of S prime retrieval facilitation is discussed.…

Assesses the sensory and cognitive functions in a right-handed male before and after partial and complete callosal commissurotomy. (Author/SK)

Consistent results of two experiments, in which undergraduate students were taught relatively technical native language vocabulary through keyword methods, showed that effectiveness of such methods depended upon whether meanings of words to be learned were abstract or concrete and whether comprehension was assessed immediately or after a delay.…
