Evaluating performance in continuous experiments with feedback to subjects

Consider an experiment in which a subject guesses repeatedly at a randomly chosen target on a continuum. To guarantee a positive probability of success, the continuum is partitioned into a finite but large number of segments. The subject is given directional feedback. General guessing strategies are characterized, and an optimal strategy is identified. The hypothesis that the subject's performance can be explained by chance alone is of interest in such experiments. A test is developed based on comparing the subject's performance to expected performance using the optimal strategy. A skill-scoring procedure is developed for assessing a subject's performance in light of the strategy used, and a test based on skill-scoring is advanced.Research by the first author is supported in part by the Air Force Office of Scientific Research under grant AFOSR 77-3180.The authors wish to thank the referees for remarks that led to improvements in both content and clarity.     

Lack of effects of anabolic-androgenic steroids on locomotor activity in intact male mice

Anabolic-androgenic steroid abusers have reported hyperactivity, euphoria, and decreased fatigue, among other behavioral effects. It has been suggested that the effects of these substances on the central nervous system are similar to those of psychostimulants; however, the influence of steroids on general locomotor activity in laboratory animals is not well understood, especially how noncastrated male rodents are affected. In this study, spontaneous locomotor activity displayed by gonadally intact male mice submitted to several experimental conditions was analyzed. Different housing conditions (individual or cohabiting with a female), diverse steroids (testosterone propionate, nandrolone decanoate, and a mixture of both steroids) and single or repeated injections were employed. At 24 hours after the injection (after the three last injections in the case of chronic treatment) spontaneous locomotor activity was registered on an activity recorder for one 15-min. period. No effects due to the treatment were found in almost every experimental condition. These results contrast with the dramatic decreases in activity described for female mice after treatment with such steroids. It seems that in intact males the steroids' influence on spontaneous locomotor activity may be more subtle than expected. These effects seem very complex depending on duration of treatment and specific situations (spontaneous or forced activity) as well as the interaction with endogenous androgen levels.     

‘Why not Lukács?’ or: on Non-Bourgeois Bourgeois Being

The Lukács Circle in Szeged, a spontaneous, unofficial organization of young Hungarian scholars and philosophy teachers, characteristically represented Georg Lukács' influence on young Hungarian intelligentsia in the period of late socialism. In this paper, the author recalls and critically analyses the intellectual milieu and motives that led a considerable part of young Hungarian intelligentsia of that time to make a cult of Lukács' philosophy. The key to the analysis is the ambiguous character of the political feelings and philosophical orientation of many young people in the period of late socialism and the paradoxical non-bourgeois bourgeois character of Lukács' philosophy. Lukács' young followers were dissatisfied with the political conditions of real socialism and with official Marxism. However, they considered themselves Marxists and were convinced by the anti-capitalist, romantic idea of democratic socialism. In the eyes of his young followers, Lukács was a genuine philosopher whose teaching was interwoven by his wide-ranging bourgeois middle-class education, promising both a real philosophical alternative to official Marxism and a high-level philosophical foundation for a non-capitalist but democratic future human history. The author argues that Lukács' philosophy did not satisfy these expectations. In his political philosophy, the philosopher could not move away from the mythological idea concerning the leading role of the communist party and therefore could not elaborate a genuine philosophical foundation for the idea of democratic socialism. Despite the superiority of his philosophy, his methodology and approach to the history of philosophy failed to provide a real philosophical alternative to the Bolshevik tradition of Marxism.     

Low platelet monoamine oxidase activity in sensation-seeking bullfighters

In this study, we attempt to demonstrate an association between low platelet monoamine oxidase (MAO) activity, as assessed by isotopic methods, and the stable behavioral pattern of sensation- and risk-seeking of professional bullfighters. Sixteen professional bullfighters were studied and compared with a control group of 46 healthy control subjects who did not engage in risky jobs or activities. The group of bullfighters had significantly reduced platelet MAO activity compared with the control group (P<0.05). Bullfighters were shown to be significantly more extroverted and sensation-seeking than controls on various temperament scales. A predisposition to engage in risky activities (eg, bullfighting) and sensation-seeking could be partly conditioned by the presence of biological components of personality manifested by a significantly decreased platelet MAO activity.     

Effects of short-term isolation on the locomotor activity of the angelfish (Pterophyllum scalare).

Two experiments were conducted to test in angelfish (Pterophyllum scalare) some implications of Gallup and Suarez's (1980) ethological model of open-field behavior and to differentiate between the initial locomotor effects of a novel environment and those of isolation per se. Juveniles placed alone in a novel environment initially showed increased locomotion compared with their previous level when kept as a group and with that of fish placed in the novel environment in groups of three and five. When placed alone in a novel tank, individuals that had already been isolated for 10 days moved about less than those that had been isolated for 4 days. During isolation, angelfish significantly reduced activity to a minimum after 3 to 4 days, and after 10 days the level was still lower than in the group situation. The results suggest that, in addition to birds and rodents, Gallup and Suarez's model is applicable to fish and may account for the effects of longer exposure to a novel environment.     

Rhesus monkey (Macaca mulatta) cool sensitivity measured by a signal detection method

Two rhesus monkeys were trained to detect cool stimuli (decrements in skin temperature from the adapted temperature) presented to the palm of the left hand after the skin had been preadapted to a 33°C temperature. The procedure was analogous to the signal detection “yes-no” method used with human observers. Receiver operating characteristic curves were generated by varying the a priori probability of stimulus oecurrence. The proportion of hits and of false alarms increased with increases in the a priori probability of stimulation. The points of isosensitivity of both subjects for cool intensities of 0.3°C, but not at greater intensities, yielded straight lines with slopes of approximately one when plotted on normal-normal coordinates. The values of the d’_s detectability index decreased from 3.52 to 0.75 for one subject and from 2.81 1to 1.28 for the other as the stimulus intensity was decreased from 0.8° to 0.15° cooling from the adapting temperature. Cool thresholds for each subject of 0.19° and 0.12°C were computed from classical psychometric functions when threshold was defined as 50% hits at a 50% probability of stimulus occurrence. These thresholds are comparable to published reports of the cool threshold for the rhesus.
