Impaired semantic memory during acute transient global amnesia

As a clinical model of hippocampal dysfunction, transient global amnesia (TGA) causes reversible memory disturbance. While episodic memory deficits in TGA patients have been extensively described, data regarding semantic memory involvement are sparse and contradictory. We report impaired semantic fluency performance in 16 patients with hippocampal lesions on MRI during acute TGA compared to their performance one day later and to that of 20 healthy subjects. Our findings support the involvement of the hippocampus in semantic retrieval.     

Positive experiences of doctoral-level supervisors-in-training conducting group-format supervision: a qualitative investigation

Experiential learning opportunities are powerful in shaping positive supervisor behaviours. We were interested in examining the positive experiences of supervisors-in-training during their first practice experience as supervisors. Our study was guided by two research questions: (a) what are the experiences that supervisors-in-training viewed as positive during the course of providing clinical supervision to master's-level counselling trainees? and (b) how did these positive experiences contribute to their professional development? We employed a variation of the consensual qualitative research method developed by Hill, Thompson, and Nutt-Williams (1997) and interviewed 10 supervisors-in-training regarding their positive experiences in supervising master's-level counselling trainees. The results included five major categories of positive experiences: (a) the positive value of feedback; (b) enhanced confidence in using a wider variety of supervision tasks and procedures; (c) the impact of the experience on other aspects of professional practice; (d) increased familiarity with the multiple roles of the supervisor; and (e) for some, increased comfort navigating co-supervision dynamics. Each of these categories included subcategories. We discuss our findings within the context of supervision training in graduate education.     

Individual Differences in Antisocial Punishment in Public Goods Situations: The Interplay of Cortisol with Testosterone and Dominance

This research investigates which endocrinological and psychological factors are associated with individuals' tendency to engage in destructive antisocial punishment, that is, to costly punish cooperative individuals in public goods situations. In this work, we focus on the interplay of endogenous cortisol with testosterone and dominance. We applied the dual‐hormone hypothesis according to which testosterone is positively associated with destructive and dominant behavior but only in individuals with low levels of cortisol. Study 1 shows that individuals are more likely to engage in destructive antisocial punishment in a public goods game with the option to punish when their testosterone level is high, given that their level of cortisol is low, which bolsters the dual‐hormone hypothesis. In contrast, no significant interaction effect of testosterone and cortisol emerges for the punishment of uncooperative free‐riders (altruistic punishment). In a second study, we build on these findings and document that self‐reported dominance is only positively associated with antisocial punishment (but not with altruistic punishment) when cortisol is low. In sum, the results indicate the importance of taking endocrinological and psychological factors (and their interactions) into account in order to reach a comprehensive understanding of individuals' behavior in social dilemma situations.

Fear conditioning and extinction in anxiety- and depression-prone persons

Anxiety and depression frequently co-occur and may share similar deficits in the processing of emotional stimuli. High anxiety is associated with a failure in the acquisition and extinction of fear conditioning. Despite the supposed common deficits, no research has been conducted on fear acquisition and extinction in depression. The main aim of the present study was to investigate and compare fear acquisition and extinction in anxiety- and depression-prone participants. Non-clinical anxious, depressive, anxious-depressive and control participants performed a fear discrimination task. During acquisition, the CS+ predicted an aversive event (unconditioned stimulus, US) and the CS? safety (no US). During extinction, the CS+ was no longer followed by the US, rendering it (temporarily) into a safety signal. On each CS participants rated their US expectancy; skin conductance responses (SCRs) were measured throughout. The expectancy scores indicated that high anxiety resulted in less safety learning during acquisition and extinction; no effect of depression was observed. SCRs showed that high-anxiety persons displayed less discrimination learning (CS+ minus CS?) during acquisition than low-anxiety persons. During extinction, high-depression persons demonstrated more discriminative SCR than low-depression persons. The observed discrepancies in response patterns of high-anxiety and -depression persons seem to indicate distinctive information processing of emotional stimuli.     

DEVELOPMENT OF ANDROGYNY

While many researchers have documented the existence of pressures toward traditional sex-typing in the family, schools, and media, little consideration has been given to the effectiveness of these sources in fostering more flexible orientations to sex-typing. The present paper focuses on the extent to which parents are able to influence their children toward the development of nonstereotyped behaviors, conceptualized here in terms of androgyny. This issue is examined through an-exploration of several theories of sex-role development and empirical research on sex-role development. Additional consideration of theories and research on life-span development and resistance among children in the current culture to nonstereotyped behavior lead to a distinction between short-term and long-term effects of nonsexist parental behavior. Although androgynous parents may not produce androgynous children, their children often do grow up to be androgynous adults.     

Doxastic divergence and the problem of comparability. Pragmatism defended further

Situations where it is not obvious which of two incompatible actions we ought to perform are commonplace. As has frequently been noted in the contemporary literature, a similar issue seems to arise in the field of beliefs. Cases of doxastic divergence are cases in which the subject seems subject to two divergent oughts to believe: an epistemic and a practical ought to believe. This article supports the moderate pragmatist view according to which subjects ought, all things considered, to hold the practically right belief in, at least, some cases of doxastic divergence. Unlike many defences of pragmatism, this paper does not aim to overcome exclusivism (briefly, the view that only epistemic, but not practical, considerations have an influence on what a subject ought to believe). Another major challenge that pragmatism faces is to show that the epistemic and the practical ought to believe are comparable. This article makes a case for their comparability.
