Count data in psychological applied research

As some authors have noticed in fields other than psychology, level of measurement and distributional characteristics of count data are commonly not taken into account, so that they are analysed as normally distributed continuous variables, and therefore some general linear model is applied. In this work, we review a random sample of 457 articles published in the last four years in journals with the highest impact factor in the Journal Citation Reports (JCR Social Sciences Edition) of the Institute for Scientific Information. The goals are to know how often count variables appear in psychological applied research and which data analyses are used when dealing with count response variables. Examination showed that there is a notable presence of count variables, especially in some topics in psychology and a remarkable misapplication of the general linear model. One deals with causes and consequences of this approach to data analysis and suggests the use of specific models to analyse count data.     

WHAT DO BELIEF ASCREBERS REALLY MEAN? A REPLY TO STEPHEN SCHIFFER

Stephen Schiffer has recently claimed that the currently popular “hidden-indexical” theory of belief reports is an implausible theory of such reports. His central argument for this claim is based on what he refers to as the “meaning-intention” problem. In this paper, I claim that the meaning-intention problem is powerless against the hidden-indexical theory of belief reports. I further contend that the theory is in fact a plausible theory of such reports.     

Positive psychotherapy for distressed cancer survivors: Posttraumatic growth facilitation reduces posttraumatic stress

Background/Objective

There is increasing evidence that positive life changes, such as posttraumatic growth (PTG), can result from the experience of coping with cancer. However, no interventions have been specifically designed to facilitate the development of PTG in cancer. In this article, we describe and assess the results of Positive Psychotherapy for Cancer (PPC) survivors. It aims to facilitate PTG as a way of achieving significant reductions in the symptoms of emotional distress and posttraumatic stress. In addition, the corroboration of this PTG facilitation is assessed using interpersonal indicators. Method: We allocated 126 consecutive survivors of cancer with high levels of emotional distress and who were seeking psychological support to either an experimental group (PPC) or a waiting list group. Results: The PPC group obtained significantly better results after treatment than the control group, showing reduced distress, decreased posttraumatic symptoms, and increased PTG. The benefits were maintained at 3 and 12 months’ follow-up. Participants’ PTG was correlated to the PTG that their significant others attributed to them, corroborating PTG facilitation. Conclusions: PPC appears to promote significant long-term PTG and can reduce emotional distress and posttraumatic stress in cancer survivors. In addition, PTG facilitation induced by PPC is corroborated by significant others.     

Reaching long-term goals based on local interaction between an organism and the environment: computer simulations based on adaptive behavior

An agent-based computer simulation created using the adaptive-behavior approach has shown that in some cases it is possible to reach a long-term goal (defined here as a desirable place far removed from the agent in time and in space) without necessarily having an exhaustive, predefined plan of action, but rather by using a set of rules on sensorimotor couplings that govern the organism's local interaction with its environment. We used an agent-based simulation program that emulated a two-dimensional microworld in which agents interacted with their environment and other agents through a set of sensorimotor couplings to reach a long-term goal. The main hypothesis was that the sensorimotor coupling, which consisted of following other agents, led to the emergence of collective behavior that enabled the agents to attain the long-term goal. We systematically varied the sensorimotor couplings that allowed agents to follow other agents, agents' perceptual field length, and the number of obstacles. In total, there were 160 independent simulations for each design cell. Analysis supported the hypothesis and suggested that, in addition to the process of reaching long-term goals, other cognitive processes, such as categorization, memory, and reasoning, can be reconsidered bearing in mind the emergence of behavior and an approach based on interaction between the organism and its environment.     

Catharsis: Psychoanalysis and the theatre

The notion of catharsis, in relation to tragedy, was introduced by Aristotle in his work Poetics. Over the centuries, Aristotle's innovative and enigmatic reference to this process has been widely commented on and given rise to intense controversy. In 1895, Freud and Breuer reconsidered this notion in their Studies on Hysteria, where they present the so-called cathartic therapeutic method. It is not, however, this aspect of psychoanalytical theory that the author of this article seeks to elucidate: drawing on a detailed study of the references to tragic catharsis in the work of Freud and Lacan, the author proposes to examine their implications for psychoanalytic treatment.With specific reference to Freud's article Psychopathic characters on the stage (1905) and Lacan's commentary on Sophocles' Antigone (1960), the author argues that catharsis is to be understood not so much as a mechanism of discharge linked to abreaction, but rather as the actual analytic process itself during which the Subject is 'unveiled' and thus faced with the enigma of his own desire.     

Psycholexical Value Factors in Spain and Their Relation with Personality Traits

The aim of the present study is to determine the structure of values in the Spanish population and its relation to the Big Five personality traits. Using a psycholexical approach, 566 words were identified as values and administered to a sample of participants who were instructed to rate the extent to which they were guided by each value. Principal components analysis revealed seven factors: Social Recognition, Competence, Love and Happiness, Benevolence, Idealism, Equilibrium and Family. The results show that there is no complete equivalence between these factors and those obtained in previous studies. However, the results are congruent with those obtained in other studies as far as the relation between values and personality traits is concerned. Copyright © 2011 John Wiley & Sons, Ltd.
