The influence of a primarily Public form of self-awareness and of Private and Public Self-Consciousness on drunken physical aggression and complex reaction-time were examined. Two forms of the balanced-placebo design were employed. Results indicated that each form of self-focus played a significant role in the determination of various aspects of drunken comportment. Consumption of alcohol did not eliminate self-aware behavior on the measures employed. Public Self-Consciousness acted to increase drunken impairment. A modified form of the balanced-placebo design proved superior to the standard version for use with moderately high doses (1.32 ml/kg) of alcohol on a measure of subjective intoxication. The implications for the literature on self-focus and drunken comportment are discussed.

The research reported is concerned with the effects of alcohol on a maze-based task which had been designed to incorporate independently each of the four behavioral processes described by Berliner, Angell, and Shearer in 1968. Such a design allows study of the relative effects of alcohol on various behavioral domains. This type of . comparison had not been previously accomplished in a single study. Further, if a task can be characterized according to the behavioral dimensions of which it is comprised and alcohol levels at which performance of the task is likely to occur can be postulated, regression equations might be of use in estimating performance decrements on the task under alcohol versus no-alcohol conditions without experimental manipulation. The development of such regression equations is a second aim of this experiment. Thirty-two subjects (16 of each gender) were given four different alcohol doses (0.00, 0.05, 0.07, and 0.09% BAC) coupled with four levels of maze difficulty. A Latin Square strategy was used to assign the BAC/Maze combinations. Each combination was repeated under speed and accuracy instructions. Analyses of variance showed that alcohol impaired performance on (most independent variables in each of the behavioral domains. However, comparisons of estimated percent differences in performance across the dimensions revealed that the cognitive processes were most impaired by alcohol while the perceptual processes were most resistant to alcohol effects. Analyses of variance also indicated that there were no performance effects attributable to gender but that maze difficulty and instruction generally affected performance in the expected directions. Regression equations which incorporated alcohol, instruction, and ratings of the contribution of each behavioral process were developed to predict task completion time. Gender did not enter into these equations. The predictions yielded by these equations are in agreement with the results found in the literature. Hence, they are satisfactory for use in estimating performance decrements due to alcohol on a task the behavioral components of which are known or can be measured. / Ph. D. / incomplete_metadata

The purpose of this study was to examine the hormonal response to acute ethanol ingestion following a bout of heavy resistance exercise in women. Eight resistance trained women completed two identical acute heavy resistance exercise tasks (AHRET). From 10-20 minutes post-AHRET, participants consumed either a grain ethanol or a placebo beverage. Blood was collected before (PRE) and immediately after the AHRET (IP) and then every 20 minutes for five hours. Blood collected after beverage ingestion was pooled into 3 batches (phases: 20-40 minutes, 60-120 minutes, and 140-300 minutes post-exercise) and analyzed for serum total testosterone (TT), free testosterone (FT), insulin-like growth factor-I (IGF-I), human growth hormone (GH), cortisol (COR), and estradiol (E2) concentrations. Circulating concentrations of TT were significantly greater at P20-40 than at PRE, P60-120, and P140-300. Circulating concentrations of FT were significantly greater at P20-40 than at all other times. Circulating concentrations of GH were significantly greater at IP than at PRE, P60-120, and P140-300. Circulating concentrations of COR were significantly greater at P20-40 than at all other times. Additionally, COR concentrations at P140-300 were significantly lower than at all other times. Circulating concentrations of IGF-1 were significantly greater at P20-40 than at P60-120 and P140-300. Circulating concentrations of E2 were significantly greater at P20-40 than at all other times. In summary, the present study demonstrated an acute modulation of the neuroendocrine milieu following a heavy resistance exercise bout in women. Ethanol ingestion appeared to have no significant effect on the characteristics of acute hormonal augmentation in TT, FT, GH, COR, IGF-1, or E2.
