When the whole is more than the sum of its parts: Group motivation gains in the wild

Whereas negative effects of groups on individual motivation have been reported for many years, recent research has begun to show when and why working in a group can produce motivation gains compared to individual work. So far, this evidence has been limited to laboratory settings and rather simple tasks. Using data from swimming competitions at the 2008 Olympics, evidence is presented that motivation gains in groups also occur in field settings with more complex tasks. Based on an instrumentality × value approach, we expect that late positions in a relay trigger motivation gains in groups due to an increase in perceived indispensability for the group outcome. This idea has been initially tested in a pilot study with competitive swimmers, demonstrating that perceived indispensability for the relay outcome indeed increases with later serial positions in a relay. Moreover, the main study with data from the 2008 Olympics revealed performance times consistent with this pattern of indispensability perceptions: while starting swimmers in the swimming relays performed at similar levels as in their individual competitions, swimmers at the later positions showed higher performance in the relay compared to their individual competition heats.

Winnicott and Derrida: development of logic-of-play

In this essay I develop the logic of play from the writings of the British psychoanalyst Donald W. Winnicott and the French philosopher Jacques Derrida. The logic of play serves as both a conceptual framework for theoretical clinical thinking and a space of experiencing in which the therapeutic situation is located and to which it aspires. I argue that both Winnicott and Derrida proposed a playful turn in Western thinking by their attitude towards oppositions, viewing them not as complementary or contradictory, but as 'peacefully-coexisting'. Derrida criticizes the dichotomous structure of Western thought, proposing playful movement as an alternative that does not constitute itself as a mastering construction. I will show that Winnicott, too, proposes playful logic through which he thinks and acts in the therapeutic situation. The therapeutic encounter is understood as a playful space in which analyst and analysand continuously coexist, instead of facing each other as exclusionary oppositions. I therefore propose the logic of play as the basis for the therapeutic encounter. The playful turn, then, is crucial for the thought and praxis expressed by the concept of two-person psychology. I suggest the term playful psychoanalysis to characterize the present perspective of psychoanalysis in the light of the playful turn. I will first present Derrida's playful thought, go on to Winnicott's playful revolutionism, and conclude with an analysis of Winicott's clinical material in the light of the logic of play.     

Attitudes Toward Parenting Strategies,Potential for Child Abuse,and Parental Satisfaction of Ethnically Diverse Low-Income U.S. Mothers

Abstract

Among a sample of 176 low-income mothers from 3 ethnic groups in the United States, the authors investigated ethnic differences in attitudes toward preferred parenting strategies, or styles; ethnic differences in the potential for child abuse; and the relationship between parenting strategies, the potential for child abuse, and parental satisfaction. They distributed the Maternal Reactions to Child's Deviant Behavior subscale (K. M. Rickard, W. Graziano, & R. Forehand, 1984), a shortened version of the Child Abuse Potential Inventory (CAPI; J. S. Milner & R. C. Wimberley, 1979), and a Parental Satisfaction Scale (N. P. Medora, S. M. Wilson, & J. Larson, 1996) to the participants. The results indicated no significant ethnic differences in preferred parenting styles. Mothers from all 3 ethnic groups ranked praise and reasoning as the 1st and 2nd preferred parenting strategies. There were no ethnic differences in the perceived potential for child abuse. Parental satisfaction was negatively related to 2 of the CAPI subscales-Loneliness and Problems. The parenting strategy reasoning was positively correlated with parental satisfaction.     

Unconscious processing modulates creative problem solving: Evidence from an electrophysiological study

Previous behavioral studies have identified the significant role of subliminal cues in creative problem solving. However, neural mechanisms of such unconscious processing remain poorly understood. Here we utilized an event-related potential (ERP) approach and sandwich mask technique to investigate cerebral activities underlying the unconscious processing of cues in creative problem solving. College students were instructed to solve divergent problems under three different conditions (conscious cue, unconscious cue and no-cue conditions). Our data showed that creative problem solving can benefit from unconscious cues, although not as much as from conscious cues. More importantly, we found that there are crucial ERP components associated with unconscious processing of cues in solving divergent problems. Similar to the processing of conscious cues, processing unconscious cues in problem solving involves the semantic activation of unconscious cues (N280–340) in the right inferior parietal lobule (BA 40), new association formation (P350–450) in the right parahippocampal gyrus (BA 36), and mental representation transformation (P500–760) in the right superior temporal gyrus (BA 22). The present results suggest that creative problem solving can be modulated by unconscious processing of enlightening information that is weakly diffused in the semantic network beyond our conscious awareness.     

The Potentiality of the Embryo and the Somatic Cell

Recent arguments on the ethics of stem cell research have taken a novel approach to the question of the moral status of the embryo. One influential argument focuses on a property that the embryo is said to possess—namely, the property of being an entity with a rational nature or, less controversially, an entity that has the potential to acquire a rational nature—and claims that this property is also possessed by a somatic cell. Since nobody seriously thinks that we have a duty to preserve the countless such cells we wash off our body every day in the shower, the argument is intended as a reductio ad absurdum of the claim that the embryo should be afforded the same moral status as a fully developed human being. This article argues that this argument is not successful and that it consequently plays into the hands of those who oppose embryonic stem cell research. It is therefore better to abandon this argument and focus instead on the different argument that potentiality, as such, is not a sufficient ground for the creation of moral obligations towards the embryo.

Refusing to be excluded: finding ways of integrating psychotherapeutic modalities to the emerging needs of a Pupil Referral Unit

This paper describes the application of child psychotherapy, its theory and practice, in a Pupil Referral Unit (PRU). It examines the importance of a flexible approach to outreach work and the implementation of interventions that take into consideration both the internal and the external world of the adolescent. Furthermore, the process of development of a psychodynamic group with PRU students is described and illustrated. Additionally, it explores the importance of developing psychodynamic models of working with allied professionals in supervision and collaborative efforts in general. The paper explores the usefulness of the concept of mentalisation when working in the context of schools as well as the need to develop an accessible psychodynamic language that enables multidisciplinary collaboration. Overall, this paper reflects on the importance of holding in mind the challenge of balancing the needs of the external and the internal world, which becomes very evident in the process of outreach work.
