Getting to know you: How we learn new faces

Previous work has shown an advantage for matching the internal features of familiar faces in contrast to an advantage for the external features of unfamiliar faces. In the current experiment, we tracked this shift towards an internal feature advantage as subjects were familiarized with a set of initially unfamiliar faces. They were asked to learn a set of 24 faces from video images and complete a face matching task on 3 consecutive days. Half of the faces were learned from moving images while the others were learned from static images to determine whether movement was necessary to produce the internal advantage found when matching familiar faces. We found that by the end of the 3 days, performance on the internal features had improved and was equivalent to performance on the external features. In contrast, matching of the external features remained at a relatively constant level across the experiment. Faces were learned equally well from moving and static images suggesting that movement is not necessary to promote learning of the internal features.     

Psychosocial vulnerability, life stress, and suicide ideation in a jail population: a cross-validation study

The purpose of this present investigation was to cross-validate a stress-psychosocial vulnerability model of suicidal ideation and behavior in a jail population. Measures of social alienation, cognitive distortions, adaptive resources, situational (jail environment) stress, depression, hopelessness, and suicide ideation were administered to 146 male inmates at a county jail facility. It was predicted that each of the vulnerability factors, in addition to jail stress, would be significantly related to suicide ideation among inmates. Furthermore, it was hypothesized that psychosocial vulnerability among inmates would interact with jail stress to best explain suicide intent. The result of a multiple-regression analysis, stepwise forward-inclusion algorithm, indicated that 51% of the variation in suicide ideation could be accounted for by the linear combination of low reasons for living, irrational beliefs, jail stress, and loneliness. In addition, when the variables were entered into a hierarchical multiple-regression model, interactions between select psychosocial vulnerability factors and jail stress were found to best explain suicide intent. Results of the study are discussed in terms of the proposed model, and implications for future research and prevention efforts in jail suicide are noted.     

Concurrent validity of a stress-vulnerability model of suicidal ideation and behavior: a follow-up study

A follow-up study to test the concurrent validity of a stress-vulnerability model of suicidal ideation and behavior was conducted. A total of 202 college students (139 females, 63 males) completed self-report measures of life stress, loneliness, depression, dysfunctional cognitions, reasons for living, hopelessness, current suicide ideation, and predictions of future suicide probability. The results of a multiple-regression analysis indicated that 30% of the variation in suicide ideation scores could be accounted for by the linear combination of negative life stress, depression, loneliness, and few reasons for living. The linear combination of current suicide ideation, hopelessness, dysfunctional cognitions, and few reasons for living explained 56% of the variance in self-predicted future suicide probability. The results are interpreted as being supportive of the proposed model.     

Human neuropsychology: Some differences between korsakoff and normal operant performance

Summary Operant reinforcement schedules were used to investigate the effects of changes in reinforcement rates on the behavior of alcoholic Korsakoff (amnesic) patients and normal control subjects. In one test, both groups were exposed to pairs of variable-interval (VI) reinforcement schedules which operated concurrently. The distribution of reinforcements controlled the distribution of responses of normal subjects to a significantly greater extent than those of the Korsakoff patients. In a second test, two VI reinforcement schedules were arranged to run one at a time in succession. Reinforcement-rate differences with the successive (multiple) schedules did not produce corresponding response-rate differences for either group of subjects. The findings stress the complexity of the alcoholic Korsakoff syndrome, and emphasize the need to consider possible motivational abnormalities as determinants of alcohol-induced amnesia. In addition, results underscore both the value and the limitations of using operant procedures in human learning research.Supported in part by PHS Grants NS 07615 and NS 06209, by PHS RCDA K04 NS 00161 to M.

Love and the addicted physician

This paper reviews the cases of two addicted physicians. One is dead and the other alive and well as a result of the heroic and compassionate effort of his friends. We offer speculations regarding the physicians' special vulnerabilities and the role of a tough love in transcending these vulnerabilities.     

Gender differences in the psychosocial correlates of suicidal ideation among adolescents.

Gender differences in the psychosocial correlates of suicidal ideation were studied. A sample of 613 high school students (ages 14-19) completed measures of suicidal ideation, depression, hopelessness, life stress, loneliness, alcohol and drug use, and reasons for living. The results of a discriminant function analysis indicated that males reported higher loneliness and substance abuse scores than females whereas females reported greater suicidal ideation, depression, and reasons for living. The results of multiple regression analyses found that, although the same four variables, depression, hopelessness, substance abuse, and few reasons for living emerged as significant predictors of suicidal ideation in both samples, the predictive equation accounted for more of the variance in ideation scores in females (57%) than in males (46%). In a final analysis a discriminant function analysis of the subscales of the reasons for living inventory revealed that females have a greater fear of death and injury whereas males have a greater fear of social disapproval over having suicidal thoughts. This may account for the greater rate of suicide completing among males. Fear of social disapproval, more anger and impulsivity, and less help-seeking behavior among males are offered as potential variables to explain the observed gender differences.     

Future Thinking in Disadvantaged Situations: The Role of Outcome Delays and Competitive Issues in Negotiation

Extant literature suggests that delaying the outcomes of negotiations can have salutary effects on the joint outcomes of participants. However, this literature has not examined the impact that outcome delays have on the success of individual negotiators. We argue that in situations where a player's preference on an issue involves a lack of legitimacy, an outcome delay may advantage the presentation of that issue. In addition, we suggest that this effect is more likely to be present in situations where competition is high, specifically, where the parties have few opportunities for cooperation. An experimental dyadic negotiation exercise involving 306 undergraduate participants was conducted to test these hypotheses. Results suggest that the introduction of an outcome delay helps to reduce the negative effects of a legitimacy disadvantage in the absence of alternate opportunities for collaboration.     

The effects of member expertise on group decision-making and performance

This study assesses the effects of member expertise on group decision-making and group performance. Three-person cooperative groups and three independent individuals solved either an easy or moderately difficult version of the deductive logic game Mastermind. Experimental groups were given veridical performance information, i.e., the members' rankings on prior individual administrations of the task. Control groups were not provided with this information. Results supported the predictions of this study: (1) groups gave more weight to the input of their highest performing members with the group decision-making process being best approximated by post hoc “expert weighted” social decision schemes and (2) groups performed at the level of the best of an equivalent number of individuals.     

Reflexivity and Interpretive Sociology: The Case of Analysis and the Problem of Nihilism

This paper addresses the problem of reflexivity in modern social inquiry in general and in sociology in particular. This problem is inherited from Weber's very conception of sociology, is transformed by phenomenology and ethnomethodology, deepened by the linguistic turn of hermeneutics and Wittgenstein's later philosophy, and has been the central concern of the work of Alan Blum and Peter McHugh. The issues and spectres raised by reflexivity are methodological arbitrariness, the need to take responsibility for one's own talk (and the cultural assumptions embedded in talk) and, finally, the deep fear of nihilism – the sense that with regard to inquiry (along with everything else in the world) nothing matters. As such, reflexivity raises the most fundamental issue that can be raised for modern social inquiry. Through an oriented interpretation of the work of Blum and McHugh and other contemporary social theorists (particularly Gadamer and Arendt), this paper works through what a dialectical engagement with these issues look like.
