Interoceptive and exteroceptive cues in the tolerance of the ethanol ataxic effect in rats

In the current analysis of classic conditioning with regard to the phenomenon of drug tolerance, there is empirical evidence of interoceptive pharmacologic cues and of exteroceptive cues, which are associated with the effect of the drug. The former could overshadow the latter. The aim of the present investigation was to contribute experimental data about the interaction that occurs between these two kinds of cues. For this purpose, a set of interoceptive and exteroceptive cues was presented as conditioned stimulus, together with an unconditioned stimulus that corresponded to the ataxic effects of ethanol. The results showed that the interoceptive cues were associated with the ataxic effect of ethanol, and they produced a tolerance response of the same intensity as the exteroceptive cues.     

Reframing the DSM‐IV‐TR From a Multicultural/Social Justice Perspective

The Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) represents a medical model that can be reframed for more effective use in counseling. To achieve this goal, the authors describe how they can shift from client diagnosis to case formulation. In describing this shift, the authors offer an example of a theory‐based etiology and relate case formulation to specific counseling interventions.     

Temperamental profiles and linguistic development: Differences in the quality of linguistic production in relation to temperament in children of 28 months

The temperamental constellations that can be found in the infant population may influence the development trajectories of single domains of knowledge, such as that relative to language. The main objective of this study is to identify temperamental profiles to which one associates different levels of linguistic competence and to identify the profile associated with the highest risk for language acquisition. The temperamental characteristics of a sample of 106 children of 28 months attending day-care centres were surveyed and three temperamental profiles were highlighted: a profile typical of the Italian population which grouped most of the children; another made up of easily distractible and not very persistent children, who show a poor capacity to modulate motor activity and finally, the third with children inhibited in new situations. A comparison of the three groups on the basis of the level of linguistic competence revealed important differences regarding certain indices such as the vocabulary size and composition: in particular, the group of “inattentive” children has a more “immature” vocabulary composition, characterised by the presence of more primitive components of the lexical repertory.     

Carmen Amaya: Gypsy Princess, Flamenco Dancer, and the Role of the Family

Carmen Amaya was a great Spanish Flamenco dancer raised in the Gypsy tradition, which strictly prescribes, among other things, gender obligations. The proper behavior of women is to bear children and maintain the home. Carmen, from an early age, showed extraordinary skill in the dance form that the Gypsies brought to Spain. Her grasp of the intense, sensual dance was quickly recognized and she became famous throughout the world. But she was trapped in a universal problem: How much loyalty does a great artist owe to family? She died of kidney failure at age 50 in 1963. Hers is an extreme case that focuses attention on a universal problem. She did not draw a dividing line between herself and family tradition.     

Experiential avoidance and aversive visual images: response delays and event-related potentials on a simple matching task

In Experiment 1, participants high (n=15) or low in avoidance (n=14), as measured by the Acceptance and Action Questionnaire, completed a simple matching task that required them to choose whether or not to look at an aversive visual image. Only the high-avoidance participants took longer to emit a correct response that produced an aversive rather than a neutral picture. Additionally, the high-avoiders reported greater levels of anxiety following the experiment even though they rated the aversive images as less unpleasant and less emotionally arousing than their low-avoidant counterparts. In Experiment 2, three groups, representing high-, mid- and low-avoidance (n=6 in each) repeated the matching task with the additional recording of event-related potentials (ERPs). The findings of Experiment 1 were replicated in terms of reaction times and subjective ratings. The ERPs confirmed that the participants attended to the content of the images and differentiated between the aversive and neutral image types. The ERPs also showed significantly greater negativity for electrodes over the left hemisphere relative to the midline for only the high-experiential avoidance (EA) group. Given the left hemisphere dominance for language, the data suggest that the high-EA group engaged in verbal strategies to regulate their emotional responses.     

Abductive reasoning in neural-symbolic systems

Abduction is or subsumes a process of inference. It entertains possible hypotheses and it chooses hypotheses for further scrutiny. There is a large literature on various aspects of non-symbolic, subconscious abduction. There is also a very active research community working on the symbolic (logical) characterisation of abduction, which typically treats it as a form of hypothetico-deductive reasoning. In this paper we start to bridge the gap between the symbolic and sub-symbolic approaches to abduction. We are interested in benefiting from developments made by each community. In particular, we are interested in the ability of non-symbolic systems (neural networks) to learn from experience using efficient algorithms and to perform massively parallel computations of alternative abductive explanations. At the same time, we would like to benefit from the rigour and semantic clarity of symbolic logic. We present two approaches to dealing with abduction in neural networks. One of them uses Connectionist Modal Logic and a translation of Horn clauses into modal clauses to come up with a neural network ensemble that computes abductive explanations in a top-down fashion. The other combines neural-symbolic systems and abductive logic programming and proposes a neural architecture which performs a more systematic, bottom-up computation of alternative abductive explanations. Both approaches employ standard neural network architectures which are already known to be highly effective in practical learning applications. Differently from previous work in the area, our aim is to promote the integration of reasoning and learning in a way that the neural network provides the machinery for cognitive computation, inductive learning and hypothetical reasoning, while logic provides the rigour and explanation capability to the systems, facilitating the interaction with the outside world. Although it is left as future work to determine whether the structure of one of the proposed approaches is more amenable to learning than the other, we hope to have contributed to the development of the area by approaching it from the perspective of symbolic and sub-symbolic integration.

Sports participation and fair play

This study examined whether the participation in intermediate contact sports affects the opinions about the behaviors and attitudes of fair play in the sports context and whether these effects are influenced by ego orientation. The participants were high level sportsmen from university and professional basketball and football players (N = 131). They filled in questionnaires to assess their participation in sports, their goal orientations, and their fair play attitudes and behaviors. The analyses of the structural equation model indicated that participation in intermediate contact sports predicted ego orientation; these analyses consecutively predicted low levels of fair play. The direct effects of sports participation in fair play decreased significantly in the presence of ego orientation, indicating that the last construct partially mediates the relation between the first two variables. These discoveries help us to better understand the processes that operate in contact sports. Finally, their implications for eliminating unsportsmanlike behaviors are discussed.     

The impact of training on interpersonal influence

Contemporary research on interpersonal influence has shown that individuals scoring high in Need for Cognition (NC) are able to generate a large number of arguments in order to convince other people. However, research has also shown that such an effort does not necessarily lead them to be more persuasive or more efficient in their group performance. The present research analysed this state of affairs, replicating and extending previous research by showing that appropriate training in socio-emotional group dimensions can increase group performance for individuals high in NC. Potential underlying mechanisms for such an effect are discussed.
