Chinese undergraduates' preferences for altruistic traits in mate selection and personal advertisement: Evidence from Q‐sort technique

Human's preferences for altruistic mates have been confirmed by many researchers. Under the deep influence of Confucianism that authorised more parental control over offspring's mate selection, Chinese people's mating strategies and mate preferences may be different from what the evolutionary psychologists have suggested. This study used the Q‐sort technique to assess the roles of altruistic traits in mate selection and personal advertisement. A total of 200 university students participated in the Q‐sort procedures and were asked to sort 50 traits (among which altruistic traits were mixed) according to their importance when choosing (or advertising to) a long‐term (LT) or a short‐term (ST) mate. Our findings were quite different from prior studies. When Chinese participants chose a mate or advertised themselves to a potential mate, kin altruism was considered to be the most important trait; altruistic traits were more preferred by males than by females and females tended to advertise themselves as more altruistic; preferences for altruistic traits showed no difference between LT and ST mate selections (or between personal advertisement to a LT and a ST mate).

On understanding projective identification in the treatment of psychotic states of mind: The publishing cohort of H. Rosenfeld, H. Segal and W. Bion (1946–1957)

A publishing cohort of Kleinian analysts – Rosenfeld, Segal and Bion – implemented Klein's (1946) notions of projective identification and the 'paranoid ' and 'schizoid ' positions in the understanding of a group of psychotic disorders. The author differentiates Klein's (1946) Notes on some schizoid mechanisms paper from its revised version of 1952, maintaining that it was Rosenfeld's clinical work during this period that helped to centralize Klein's redefinition of projective identification. The stage was set for Segal 's contribution in terms of 'symbolic equations,' where the psychotic's attack on the breast left him incarcerated in internal torment and persecution, where things-in-themselves were confused with what they symbolically represented. Segal in turn linked psychotic to normal, paranoid–schizoid to depressive positions, where by means of projective identification and symbolic imagination, the patient could arouse feelings in the analyst related to sadness, guilt and loss. Bion assumed that psychotic pathology reflected disordered thinking, when the severely disturbed used language as a mode of action. The psychotic was profoundly confused between the use of thought and action in the natural world – where thought was required, he preferred action and vice versa. Bion also drew upon projective identification in a new, broader way, so that analysis could now become more of an intersubjective, bi-directional field of projective and communicational influence between patient and analyst. The paper concludes with the impact of the work of Rosenfeld, Segal and Bion and variations on the technique of analyzing psychotic states in terms of the patient's early history, transference and countertransference.

Risk-sensitive choice in humans as a function of an earnings budget

Risky choice in 3 adult humans was investigated across procedural manipulations designed to model energy-budget manipulations conducted with nonhumans. Subjects were presented with repeated choices between a fixed and a variable number of points. An energy budget was simulated by use of an earnings budget, defined as the number of points needed within a block of trials for points to be exchanged for money. During positive earnings-budget conditions, exclusive preference for the fixed option met the earnings requirement. During negative earnings-budget conditions, exclusive preference for the certain option did not meet the earnings requirement, but choice for the variable option met the requirement probabilistically. Choice was generally risk averse (the fixed option was preferred) when the earnings budget was positive and risk prone (the variable option was preferred) when the earnings budget was negative. Furthermore, choice was most risk prone during negative earnings-budget conditions in which the earnings requirement was most stringent. Local choice patterns were also frequently consistent with the predictions of a dynamic optimization model, indicating that choice was simultaneously sensitive to short-term choice contingencies, current point earnings, and the earnings requirement. Overall, these results show that the patterns of risky choice generated by energy-budget variables can also be produced by choice contingencies that do not involve immediate survival, and that risky choice in humans may be similar to that shown in nonhumans when choice is studied under analogous experimental conditions.

Earning and obtaining reinforcers under concurrent interval scheduling

Contingencies of reinforcement specify how reinforcers are earned and how they are obtained. Ratio contingencies specify the number of responses that earn a reinforcer, and the response satisfying the ratio requirement obtains the earned reinforcer. Simple interval schedules specify that a certain time earns a reinforcer, which is obtained by the first response after the interval. The earning of reinforcers has been overlooked, perhaps because simple schedules confound the rates of earning reinforcers with the rates of obtaining reinforcers. In concurrent variable-interval schedules, however, spending time at one alternative earns reinforcers not only at that alternative, but at the other alternative as well. Reinforcers earned for delivery at the other alternative are obtained after changing over. Thus the rates of earning reinforcers are not confounded with the rate of obtaining reinforcers, but the rates of earning reinforcers are the same at both alternatives, which masks their possibly differing effects on preference. Two experiments examined the separate effects of earning reinforcers and of obtaining reinforcers on preference by using concurrent interval schedules composed of two pairs of stay and switch schedules (MacDonall, 2000). In both experiments, the generalized matching law, which is based on rates of obtaining reinforcers, described responding only when rates of earning reinforcers were the same at each alternative. An equation that included both the ratio of the rates of obtaining reinforcers and the ratio of the rates of earning reinforcers described the results from all conditions from each experiment.     

Race and Countertransference: Two “Blind Spots” in Psychoanalytic Perception

In this paper I propose an approach for the evocative use and resolution of racial and countertransferential manifestations in the treatment situation. When addressed with the interest they warrant, these phenomena can become powerful tools for the advancement of the treatment, rather than blind spots. The therapist's own treatment is offered as the most likely means through which the evocative and pernicious effects of race and countertransference can be mastered.     

Robust canonical discriminant analysis

A method for robust canonical discriminant analysis via two robust objective loss functions is discussed. These functions are useful to reduce the influence of outliers in the data. Majorization is used at several stages of the minimization procedure to obtain a monotonically convergent algorithm. An advantage of the proposed method is that it allows for optimal scaling of the variables. In a simulation study it is shown that under the presence of outliers the robust functions outperform the ordinary least squares function, both when the underlying structure is linear in the variables as when it is nonlinear. Furthermore, the method is illustrated with empirical data.The research of the first author was supported by the Netherlands Organization of Scientific Research (NWO grant 560-267-029).     

The effects of prior expectations and outcome knowledge on polygraph examiners' decisions

The present study deals with the question of whether judgments made by experts working in familiar contexts are affected by prior expectations and beliefs. Two experiments in which prior expectations were manipulated were designed to determine whether and to what extent polygraph examiners are affected by their prior expectations when analyzing and interpreting polygraph charts. Prior expectations affected the examiners' judgments when the polygraph charts did not include clear indications of guilt or innocence, but when the objective physiological evidence included strong indications which clearly contradicted the examiner's expectations, judgments were not affected by these expectations. Theoretical and practical implications of these results are discussed.
