Different rates of forgetting following study versus test trials

Two experiments investigated recall following two study conditions, (1) repeated test: a study trial followed by multiple recall trials, and (2) repeated study: multiple study trials with no tests. At a retention interval of 5 minutes, repeated study produced a higher level of recall than repeated test. When the retention interval was extended, forgetting was much more rapid in the study condition, with the repeated test manipulation leading to higher recall at an interval of 7 days. We conclude that study and test trials have different effects upon memory, with study trials promoting memory acquisition, and test trials enhancing the retrieval process itself, which protects against subsequent forgetting.     

Dependency Conflict,Marital Threat,and Alcohol Consumption in a Middle-Aged Sample

The hypothesis that dependency conflict is associated with higher levels of alcohol consumption when dependency needs are threatened or thwarted was tested with a sample of 672 middle-aged, married adults with college-age children. The subjects' current level of alcohol consumption was predicted based on the present level of threat to the marital relationship (assessed by reports from several family members) and on indices of dependency need and inhibition of dependent behavior estimated from sibship size, sibship density, and sibling position. A multiple regression analysis yielded a significant two-way interaction (p < .05) between marital threat and subject sex, and a significant three-way interaction of dependency heed, inhibition of dependent behavior, and marital threat. High marital threat was associated with higher levels of alcohol consumption in men and slightly lower levels of alcohol consumption in women. Additionally, when dependency need was high, alcohol consumption was generally low, except when both inhibition of dependent behavior and marital threat were high. However, when dependency need was low, the highest alcohol consumption score occurred when marital threat was low and inhibition was high.     

A Note on the Possible Clairvoyance of Dreams

In a test of the discrepancy hypothesis of humor, Ss compared 11 comparison weights to a 90 gram standard. The 12th and 13th comparison weights were identical with, much lighter than, or heavier than the standard. More smile and laugh responses were made to the latter weights, and the number of these responses declined during the second presentation of those weights. The results supported the discrepancy hypothesis.     

Continuous Access to Competing Stimulation as Intervention for Self-Injurious Skin Picking in a Child with Autism

Children with autism frequently display self-injurious behavior (SIB), but skin picking—a less severe topography of SIB—has not been the focus of much clinical research. The present study evaluated a home-based intervention that was implemented with a 9-year-old girl who had autism and picked her fingers with resulting tissue damage. The intervention allowed the girl to hold and manipulate preferred objects during play and leisure activities. Evaluated in an ABAB reversal design, intervention essentially eliminated skin picking. Clinical and research implications are discussed.     

A Comparison of Forgetting Rates in Older and Younger Adults

Two experiments investigated the rate of forgetting for recently learned information in older and younger adults. Previous research has been inconclusive, with some studies reporting more rapid forgetting in older adults, whereas others have failed to find any age differences. In several different comparisons, older participants consistently forgot recently studied target words more rapidly than younger participants over a 1 hr retention interval. It appears that age-related difficulties in free recall become more pronounced as the interval between study and test increases, at least under some conditions. Results also confirm a powerful effect of prior testing on episodic memory: Both older and younger participants recalled more words after a delay of 1 hr if they had attempted recall shortly after the study session.     

Sensory and meaning features in stimulus recognition and associative retrieval.

Three experiments addressed the problem of isolating the effects of sensory similarity on subprocesses involved in coding paired associates. In the first, the standard recognition-recall procedure was used and stimulus similarity, concreteness, and frequency were varied. However, because of concern with the validity of this recognition procedure as a measure of functional stimulus contact, an alternative was developed. This alternative led to the second study in which only stimulus similarity was manipulated. In the third experiment, similarity was varied, and the pairs were either associatively compatible, unrelated, or incompatible. The results using the new procedure indicated that similarity consistently disrupted functional stimulus contact but not associative retrieval. By contrast, associative relatedness facilitated both subprocesses.
