In two experiments with normal male subjects, the ingestion of alcohol (1 ml/kg) immediately after learning significantly improved subsequent remembering. By comparison, marijuana (15 mg) had no significant post-acquisition effect. Facilitation of visual and verbal memory with alcohol under these conditions has implications for the interference and(More)
Three experiments were conducted to determine whether alcohol-induced impairments of memory would be reduced by providing subjects with elaborative schemas. Anomalous sentences were presented to sober or intoxicated subjects either alone or with context words to facilitate comprehension. Memory was tested immediately with a yes-no recognition task. The(More)
Drinking history and sober neuropsychologic performance were examined in 45 male university students between the ages of 21 and 30 yr. Sober performance on the Shipley-Hartford Institute of Living Scale was significantly and inversely related to the amount of alcohol consumed per drinking event. Neither frequency of drinking nor lifetime alcohol consumption(More)
The goals of the present study were to measure the relationship between alcohol consumption in 93 female social drinkers and their cognitive functioning and mood in the sober state, and to investigate the possible causal effects of alcohol consumption on these variables. In the first test session, a limited relationship was seen between previous alcohol(More)
We discuss how to find the well-covered dimension of a graph that is the Cartesian product of paths, cycles, complete graphs, and other simple graphs. Also, a bound for the well-covered dimension of Kn × G is found, provided that G has a largest greedy independent decomposition of length c < n. Formulae to find the well-covered dimension of graphs obtained(More)
The four experiments reported show that sensitivity to event frequency is diminished by alcohol intoxication. In two experiments on confusion between presented and generated words, the function relating estimated to actual frequency was steeper for sober than intoxicated subjects. In two experiments on word-frequency estimates after a word-pronunciation(More)
