How to learn the natural numbers: inductive inference and the acquisition of number concepts

Theories of number concepts often suppose that the natural numbers are acquired as children learn to count and as they draw an induction based on their interpretation of the first few count words. In a bold critique of this general approach, Rips, Asmuth, Bloomfield [Rips, L., Asmuth, J. & Bloomfield, A. (2006). Giving the boot to the bootstrap: How not to learn the natural numbers. Cognition, 101, B51-B60.] argue that such an inductive inference is consistent with a representational system that clearly does not express the natural numbers and that possession of the natural numbers requires further principles that make the inductive inference superfluous. We argue that their critique is unsuccessful. Provided that children have access to a suitable initial system of representation, the sort of inductive inference that Rips et al. call into question can in fact facilitate the acquisition of larger integer concepts without the addition of any further principles.     

Functional neuroimaging of speech perception during a pivotal period in language acquisition

A pivotal period in the development of language occurs in the second year of life, when language comprehension undergoes rapid acceleration. However, the brain bases of these advances remain speculative as there is currently no functional magnetic resonance imaging (fMRI) data from healthy, typically developing toddlers at this age. We investigated the neural basis of speech comprehension in this critical age period by measuring fMRI activity during passive speech comprehension in 10 toddlers (mean +/- SD; 21 +/- 4 mo) and 10 3-year-old children (39 +/- 3 mo) during natural sleep. During sleep, the children were presented passages of forward and backward speech in 20-second blocks separated by 20-second periods of no sound presentation. Toddlers produced significantly greater activation in frontal, occipital, and cerebellar regions than 3-year-old children in response to forward speech. Our results suggest that rapid language acquisition during the second year of life may require the utilization of frontal, cerebellar, and occipital regions in addition to classical superior temporal language areas. These findings are consistent with the interactive specialization hypothesis, which proposes that cognitive abilities develop from the interaction of brain regions that include and extend beyond those used in the adult brain.     

Cooperating If One's Goals Are Collective‐Based: Social Identification Effects in Social Dilemmas as a Function of Goal Transformation1

Prior studies of the effect of group identification on cooperation in social dilemmas have advanced 2 competing accounts: the goal‐transformation hypothesis, which holds that identification makes personal and collective goals interchangeable; and the goal‐amplification hypothesis, which states that identification induces positive expectations about others’ cooperative behavior. However, prior studies have neglected to assess the process measures necessary to pit the one account against the other. The present study showed that the effect of identification was moderated by participants’ social value orientation. Identification influenced proselfs’ cooperation more than prosocials’ cooperation. Mediational analyses further showed that the effect of our identification manipulation was mediated by participants’ sense of collective self, and not by their expectations.     

The holding/containment function in supervision groups for group therapists

Group supervision is essential for group therapists, given the difficulty of following and reflecting on the multiplicity of processes in therapy groups and the unique opportunity of exploring them as they resonate and become enacted in the supervision group. More specifically, the paper discusses the critical function of holding/containment in supervision groups. Clinical vignettes are presented to highlight the importance of the holding/containment function and the obstacles that hinder its emergence. The role of the therapist's interpretations as a primary means for ensuring effective holding and containment is examined.     

Searching for an environmental effect of parental alcoholism on offspring alcohol use disorder: a genetically informed study of children of alcoholics

The children-of-twins design was used to isolate a potentially causal environmental impact of having an alcoholic parent on offspring alcohol use disorder, by an examination of whether the children of alcoholics were at a higher risk for alcohol use disorders than were the children of nonalcoholic parents, even after correlated familial factors were controlled. Participants were 1,224 male and female twins from 836 twin pairs selected from the Australian Twin Registry, 2,334 of the twins' 18-39-year-old offspring, and 983 spouses of the twins. Lifetime histories of Diagnostic and Statistical Manual of Mental Disorders (4th ed.) alcohol use disorders were obtained by structured, psychiatric, telephone interviews conducted individually with each of the family members. Comparisons of the offspring of twins who were discordant for alcoholism indicated that there was no longer a statistically significant difference between the children of alcoholics and the children of nonalcoholics after genetic and family environmental factors correlated with having an alcoholic parent were controlled. The results of this study suggest that the direct causal effect of being exposed to an alcoholic parent on offspring alcohol use disorder is modest at best.     

"Am I going crazy, doc?": a self psychology approach to therapeutic assessment

In this case study, we explore the effectiveness of Therapeutic Assessment with a severely disturbed 25-year-old man, referred by his therapist, following Finn's (2007; Finn & Tonsager, 1992, 1997) model. This patient-therapist pair had been working together for approximately 2 months, but the therapy had ceased to progress. The therapist requested a clearer picture of his patient's affective functioning, interpersonal functioning, and self-functioning that might facilitate more effective treatment. Through a collaborative assessment process informed by the principles of Kohutian self psychology, the evaluator and patient slowly formed a working alliance that proved useful for the eventual communication to the patient of his psychologically tenuous reality. This case illustrates the utility of a collaborative, multimethod Therapeutic Assessment with a severely ill patient and the use of Therapeutic Assessment by a less experienced clinician.     

Less power or powerless? Egocentric empathy gaps and the irony of having little versus no power in social decision making

The authors investigate the effect of power differences and associated expectations in social decision making. Using a modified ultimatum game, the authors show that allocators lower their offers to recipients when the power difference shifts in favor of the allocator. Remarkably, however, when recipients are completely powerless, offers increase. This effect is mediated by a change in framing of the situation: When the opponent is without power, feelings of social responsibility are evoked. On the recipient side, the authors show that recipients do not anticipate these higher outcomes resulting from powerlessness. They prefer more power over less, expecting higher outcomes when they are more powerful, especially when less power entails powerlessness. Results are discussed in relation to empathy gaps and social responsibility.     

A social functional approach to emotions in bargaining: when communicating anger pays and when it backfires

Previous research on the communication of emotions has suggested that bargainers obtain higher outcomes if they communicate anger than if they communicate happiness because anger signals higher limits, which in turn leads opponents to give in. Building on a social functional account of communicated emotions, the authors demonstrate that the behavioral consequences of communicated anger strongly depend on structural characteristics of the bargaining situation. The results of 3 experimental studies on ultimatum bargaining corroborate the notion that communicated anger signals higher limits and that emotion effects are contingent on bargainers' expectation that low offers will be rejected. The data also indicate, however, that communicating anger in bargaining may backfire. The findings suggest that bargainers who communicate anger may obtain lower outcomes (a) when their opponent has a possibility to deceive them during bargaining and (b) when the consequences of rejecting their opponent's offer are low. Taken together, the current article reveals the boundary conditions of successful communication of anger in bargaining.     

Contemplative withdrawal in the Hellenistic age

I reject the traditional picture of philosophical withdrawal in the Hellenistic Age by showing how both Epicureans and Stoics oppose, in different ways, the Platonic and Aristotelian assumption that contemplative activity is the greatest good for a human being. Chrysippus the Stoic agrees with Plato and Aristotle that the greatest good for a human being is virtuous activity, but he denies that contemplation exercises virtue. Epicurus more thoroughly rejects the assumption that the greatest good for a human being is virtuous activity. He maintains that the greatest good for a human being is the tranquility that virtuous activity always and contemplative activity sometimes brings about.
