Mental representation and hypothetico-deductive reasoning: The case of the THOG problem

Summary This article reports three experiments that deal with the source of the difficulty of Wason's (1977) THOG problem. The solution of this problem demands both the postulation of hypotheses and a combinatorial analysis of their consequences. Experiment 1 showed that the generation of the hypotheses is not in itself sufficient to solve the problem. Experiment 2 showed that a version presenting a plausible context for separating the level of data from that of hypotheses produced a better performance than both the original abstract version and a thematic version lacking the plausible context separating the levels. Experiment 3 gave evidence that this context can produce facilitation even with the geometric material of the classic version. This experiment also showed that a pictorial presentation of data and a verbal presentation of hypotheses affect performance negatively. The results demonstrate the role of problem representation in problem solving, and, in particular, the role of homogeneity in representing data and hypotheses in hypothetico-deductive reasoning.     

Hermeneutics and the Philosophy of Medicine: Hans-Georg Gadamer'sPlatonic Metaphor

Taking as our starting point Plato'smetaphor of the doctor as philosopher we reflect on some aspects of the epistemological status of medicine. The framework to this paper is the hermeneutics of Hans-Georg Gadamer which shows the paradoxical nature of Western medicine in choosing the body-object as its investigative starting point, while in actual fact dealing with subjects. Gadamer proposes a model of medicine as the art of understanding and dialogue, which is capable of bringing together its various constituent parts, i.e. knowledge, knowing how to do and knowing how to be, in medical practice and in the physician'straining. The paper concludes with a brief discussion of the dyadic figure of the physician as Platonic master of the living totality and wounded healer, capable of activating the patient'sself-healing capacity.     

Same-sex parent families in Italy: Validation of the Coparenting Scale-Revised for lesbian mothers and gay fathers

Even though Italy is still struggling to establish equal rights and access to assisted reproduction techniques for sexual minorities, an increasing number of lesbian women and gay men are now becoming parents. There are only a few studies that have evaluated coparenting in same-sex couples. However, these addressed adoptive couples and not the lesbian and gay parent families through donor insemination or surrogacy, respectively. This study examined the psychometric properties of the Coparenting Scale-Revised and its relationship with dyadic adjustment, discipline management, and internalized sexual stigma in Italian same-sex-planned families. The factor structure showed a satisfactory internal consistency and criterion validity with correlates of coparenting behaviours. While Family Integrity factor was confirmed, Disparagement and Reprimand dimensions collapsed into Conflict factor. Non-genetic parents showed lower levels of conflict than genetic parents. Most importantly, coparenting emerged as a significant function not shaped by gender, but influenced by parental status and internalized sexual stigma.     

When Parsimony Subdues Distinctiveness: Simplified Public Perceptions of Politicians' Personality

Voters develop uniquely simplified perceptions of political candidates' personalities during election campaigns. In an earlier study, voters described their own personalities, and also those of celebrities, using the same five factors typical of the Big Five model of personality. In contrast, the appraisal of political candidates' personalities by voters in both Italy and the United States was reduced to only a few factors. The present research extends that exploration of the relationship between personality and politics to the public's perception of politicians' personalities across a wider variety of politicians and across a long time span after an election campaign. Two studies conducted in Italy, with more than 3,000 voters, replicated the earlier results: The factors of Energy and Agreeableness are primary anchors for evaluating politicians' personalities both during campaigns and for several years thereafter. Also uncovered were congruences between the ways that voters tend to present themselves (self-schemata) and the schemata they use to evaluate candidates representing their political preference.     

Children's understanding of posterior probability

Do young children have a basic intuition of posterior probability? Do they update their decisions and judgments in the light of new evidence? We hypothesized that they can do so extensionally, by considering and counting the various ways in which an event may or may not occur. The results reported in this paper showed that from the age of five, children's decisions under uncertainty (Study 1) and judgments about random outcomes (Study 2) are correctly affected by posterior information. From the same age, children correctly revise their decisions in situations in which they face a single, uncertain event, produced by an intentional agent (Study 3). The finding that young children have some understanding of posterior probability supports the theory of naive extensional reasoning, and contravenes some pessimistic views of probabilistic reasoning, in particular the evolutionary claim that the human mind cannot deal with single-case probability.     

Assessing regulatory emotional self-efficacy in three countries

The Regulatory Emotional Self-Efficacy (RESE) scale was developed to assess perceived self-efficacy in managing negative (NEG) and in expressing positive (POS) affect (G. V. Caprara & M. Gerbino, 2001). In this study of young adults, the factorial structure of the RESE scale was found to be similar in Italy, the United States, and Bolivia. In addition to a factor for POS, NEG was represented by a second-order factor of 2 different negative affects: despondency-distress (DES) and anger-irritation (ANG). Overall, there was partial invariance at both metric and scalar levels across gender and countries. Discriminant and convergent validity of the RESE scale was further examined in the Italian sample. Stronger patterns of association of POS with prosocial behavior, of ANG with low aggressive behavior problems and irritability, and of DES with low anxiety/depressive problems and shyness and high self-esteem were found.     

Reciprocal Relations Among Self-Efficacy Beliefs and Prosociality Across Time

ABSTRACT The present study examined the longitudinal relations between individuals' prosociality and their self-efficacy beliefs in regard to emotional regulation and responding empathically to others' needs. The participants were 244 females and 222 males with a mean age of 17 years ( SD =1.5) at T1, 19 years ( SD =1.4) at T2, and 21 years ( SD =1.6) at T3. The findings corroborated the posited paths of relations assigning empathic self-efficacy a major role in predicting the level of individuals' prosociality. Empathic self-efficacy beliefs mediated the relations of regulative emotional self-efficacy beliefs to prosocial tendencies such as caring, sharing, helping, and empathic concern toward others. The posited conceptual model accounted for a significant portion of variance in prosociality and has implications for interventions designed to promote and sustain prosociality.     

Intentional attunement: mirror neurons and the neural underpinnings of interpersonal relations

The neural circuits activated in a person carrying out actions, expressing emotions, and experiencing sensations are activated also, automatically via a mirror neuron system, in the observer of those actions, emotions, and sensations. It is proposed that this finding of shared activation suggests a functional mechanism of "embodied simulation" that consists of the automatic, unconscious, and noninferential simulation in the observer of actions, emotions, and sensations carried out and experienced by the observed. It is proposed also that the shared neural activation pattern and the accompanying embodied simulation constitute a fundamental biological basis for understanding another's mind. The implications of this perspective for psychoanalysis are discussed, particularly regarding unconscious communication, projective identification, attunement, empathy, autism, therapeutic action, and transference-countertransference interactions.     

Intellectual ability, learning style, personality, achievement motivation and academic success of psychology students in higher education

This study is directed towards an integration of intellectual ability, learning style, personality and achievement motivation as predictors of academic success in higher education. Correlational analyses partly confirmed and partly disconfirmed our expectations in a sample of 409 first-year psychology students. Consistent with the literature, intellectual ability and achievement motivation were associated positively with academic success. For the meaning directed, reproduction directed and application directed learning style, no positive association with academic success could be detected. The undirected learning style, however, appeared to be a consistent negative predictor. For the Big Five personality factors (extraversion, agreeableness, conscientiousness, neuroticism and openness to experience), a consistent, positive association for conscientiousness with academic success was found. The very first examination at the university came out as the most important predictor for academic success, even after two and three years of study. The implications of the results are discussed in relation to the literature and the policy of the Dutch Ministry of Education.
