Unconditioned sexual incentive motivation in the male Norway rat (Rattus norvegicus)

Sexual incentive motivation was evaluated in a procedure consisting of a large open field where incentive animals were confined behind wire mesh openings. When sexually inexperienced male rats (Rattus norvegicus) were exposed to the receptive female-male incentives, they spent more time close to the female. If the incentives were receptive female-nonreceptive female, the receptive female was preferred. However, when the alternatives were nonreceptive female-male, no preference was obtained. Castration abolished preference for the receptive female, and treatment with testosterone propionate restored it. Estradiol plus oil is as efficient as estradiol plus progesterone for giving the ovariectomized female incentive properties. The living female can be replaced with female odor. Sexual experience did not have any long-term effects on the female's incentive value, but immediately preceding limited sexual activity enhanced it     

Exceptional memorizers: made,not born

In a recent study, Maguire and colleagues failed to find systematic differences in brain anatomy between world-class memory performers and matched control subjects. The world-class performers exhibited distinctive patterns of brain activation during memorization, but these patterns were directly attributable to the experts' unique encoding strategies and acquired memory skills. Discussed here are the implications for broad attainability of highly skilled memory performance in professional and everyday activities.     

A measure for the assessment of eating disorders: reliability and validity studies of the Rating of Anorexia and Bulimia interview - revised version (RAB-R)

The Rating of Anorexia and Bulimia interview (RAB) is a Swedish semi-structured interview for clinical and research purposes for a wide range of eating disorder symptoms and related psychopathology. The objectives were to evaluate the reliability and validity of a revised RAB version (RAB-R). The RAB-R was assessed in terms of internal consistency, inter-rater and test-retest reliability, and criterion and convergent validity. Samples included a clinical sample of eating disorder patients (n = 71) and a sample of randomly drawn female controls (n = 31). The RAB-R showed satisfactory internal consistency, inter-rater and test-retest reliability, correlated well with related measures, and discriminated between patients and normal controls. We conclude that the RAB-R is a promising interview instrument and continued evaluation should focus on comparing subgroups of eating disorder patients with other clinical groups.     

Cognitive processes operating in hindsight

The aim of this investigation was to study the cognitive processes involved in the "knew-it-all-along" effect, especially in regard to use of inferential processes. The results of three experiments showed that the magnitude of the phenomenon did not increase with more use of inferential processes. It is proposed that only under misleading circumstances do inferential processes associated with overconfidence increase the magnitude of the phenomenon. For a majority of the tasks introspectively classified as solved by pure guessing, the hindsight phenomenon entirely disappeared whereas "intuition" tasks lead to the strongest bias. The results are generally consistent with the accuracy-assessment model (A. Winman et al. , 1998).     

Discriminant validation of measures of organizations commitment,job involvement,and job satisfaction among Swedish army officers

The discriminant validity of measures of job involvement, job satisfaction and organizational commitment was tested with data from 467 army officers in Sweden. Confirmatory-factor analysis showed a close fit between the proposed three-factor model and the data. Further, six of eleven job and health correlates related differently to the three attitude vairables. The results indicate that job involvement, job satisfaction and organizational commitment represent three empirically distinct constructs. Implications for future research discussed.     

I want to be creative,but … preference for creativity,perceived clear outcome goals,work enjoyment,and creative performance

In today’s quickly changing work environment, many individuals want to be creative at their workplace, but only some of them succeed at manifesting these tendencies. In three studies, using both field and experimental data, we focused on transforming individuals’ preference for creativity, defined as an inclination for liking and wanting to be creative, into actual creativity. We first conducted a pilot Study 1 to establish discriminant validity to related constructs and provided initial evidence on predictive and incremental validity of the preference-for-creativity scale. Next, we performed a field Study 2, where we found that transforming preferences for creativity into supervisor-rated creativity is contingent upon employees’ perceptions of clear outcome goals. Clear outcome goals fostered individuals’ preference for creativity to result in higher levels of supervisor-rated creative behaviour—a finding that was replicated in an experimental Study 3. Furthermore, we explored whether work enjoyment mediated the moderated relationship between preference for creativity and creative outcomes. The results supported our mediated moderation model, whereby the manipulation of clear goals led to higher work enjoyment, influencing individuals’ preference for creativity to result in higher ratings of their creative outcomes.     

Universal parent support groups for parents of adolescents: Which parents participate and why?

Leader‐led parent support groups, offered universally to parents of adolescents, are increasingly common, yet little is known of the parents who use this support. The study presented here explored the characteristics of parents of 10‐ to 17‐year‐olds (N = 192) who had enlisted in universal support groups and their reasons for enrollment. Sociodemographic factors (parents’ country of origin, educational level, long‐term sick‐leave or unemployment, and marital status) were compared to the general population (Statistics Sweden, 2012 ) and parents’ psychological health and children's psychiatric symptoms were compared to a control group (the BITA study). Results showed that support group parents reported more psychosocial difficulties, such as higher frequency of long‐term sick‐leave or unemployment, more symptoms of anxiety and depression and more psychiatric symptoms in their children than parents in general. While about a fifth of the parents had problem‐oriented (targeted) reasons for enrollment, most parents had general (universal) reasons. Thus, the universal approach does seem to reach its intended recipients.     

Underconfidence in sensory discrimination: The interaction between experimental setting and response strategies

In a recent issue of this journal, Baranski and Petrusic (1994) presented empirical data revealing overconfidence in sensory discrimination. In this paper, we propose an explanation of Baranski and Petrusic’s results, based on an idiosyncrasy in the experimental setting that misleads subjects who are using an unwarranted symmetry assumption. Experiment 1 showed that when this hypothesis is controlled for, a large underconfidence bias is obtained with Baranski and Petrusic’s procedure. The results of Experiment 2 confirmed that overconfidence is difficult to obtain in subject-controlled sensory discrimination tasks, even for a very low proportion of correct responses. The different results obtained in sensory and cognitive tasks suggest that one should not uncritically draw parallels between confidence in sensory and cognitive judgments.
