Cooperative responding in rats: II. Performance on fixed-ratio schedules of mutual reinforcement

Coordinated responses of 5 dyads of rats were investigated under fixed-ratio (FR) schedules of mutual water reinforcement. Coordinated responding was defined as 2 consecutive lever-presses, 1 from each of 2 rats, occurring <.5 s apart. In the FR schedules, each coordinated episode was defined as 1 response in the FR sequence. The size of FR schedules was parametrically manipulated assuming the values of FR 1, 6, 12, 18, 24, 30, 50, and 9, in this order. Each FR remained in effect until responding reached stability. Under all conditions, pairs of rats received access to water simultaneously (mutual reinforcement). Rates and proportions of coordinated responding showed a bitonic inverted U-shaped function of ratio size. Postreinforcement pauses increased systematically as the interreinforcement interval increased. Local rates and proportions increased as a function of response location within ratios. Results of a control condition with relaxed temporal constraints for mutual reinforcement showed decreases in rates and proportion of coordinated responses, suggesting that the coordinated responses were controlled by the mutual reinforcement contingencies. The present experiment showed that coordinated responding is quantitatively affected by 3 properties of FR schedules: response requirement, reinforcement rates, and proximity to reinforcement.     

COCAINE ADDICTS AND THEIR FAMILIES: AN EMPIRICAL STUDY OF THE PROCESSES OF IDENTIFICATION

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father"mother"son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction. The utilisation of very regressive defence mechanisms, above all of projective identification, was the predominant mode of procedure in triads with a dependent child. In comparisons between the fathers the odds ratio (OR) for projective identification was 8.66 to 1, which points to the association between cocaine addiction and the primitive mental functioning of the fathers. With empirical methodology these findings serve to corroborate the psychoanalytical conclusions based on studies of single case studies, testifying that the dysfunctions of identificatory phenomena in familial functioning are predominant in the mental organisation of cocaine addicts.     

Positioning Microanalysis: Studying the Self Through the Exploration of Dialogical Processes

Self-multiplicity is a widely recognized phenomenon within psychology. The study of how self-continuity emerges amidst self-multiplicity remains a crucial issue, however. Dialogical approaches are widely viewed as suitable for developing this field of study but they demand coherent methods compatible with their theoretical bases. After reviewing the available methods for the study of the dialogical self, as well as other dialogical methods for the study of psychotherapy, we conclude that we still lack a method which can be used by external observers and is devoted to the systematic tracing of the dialogical dynamics of self-positions as they unfold over time. A new method, positioning microanalysis, is described in detail as a possible way to overcome current limitations in methods focused on the dialogicality inherent in selfhood processes. Positioning microanalysis takes a genetic-developmental perspective on dialogical processes in the self and allows for the depiction of microgenetic movements of self-positions over time and the establishment of more or less stable sequences or patterns of positions. This is illustrated by its application to an emotion-focused therapy session.     

A Pilot Study Addressing the Impact of Religious Practice on Quality of Life of Breast Cancer Patients During Chemotherapy

The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.     

Religious belief and intelligence: Worldwide evidence

Is there a positive impact of intelligence on religious disbelief after we account for the fact that both average intelligence and religious disbelief tend to be higher in more developed countries? We carry out four beta regression analyses and conclude that the answer is yes. We also compute impact curves that show how the effect of intelligence on atheism changes with average intelligence quotients. The impact is stronger at lower intelligence levels, peaks somewhere between 100 and 110, and then weakens. Bootstrap standard errors for our point estimates and bootstrap confidence intervals are also computed.     

Perversion – structure or organization?

Abstract

This paper aims to discuss perversion, its implications in the clinical setting, and some of the key concepts around it. First, the etymology of the words “perversion”, “structure”, and “organization” is analyzed. Next follows a discussion on the sexual organization of instincts – from the Unconscious to the Oedipus complex in Freud and Lacan – setting the ground for a disavowal-based theory of perversion. An instructive approach has been chosen so as better to organize the various points presented.

Laender NR et al. Perversion – Struktur oder Organisation?

Der Aufsatz diskutiert die Perversion, ihre Auswirkungen im klinischen Setting und einige Schlüsselkonzepte. Zuerst wird die Herkunft der Wörter Perversion, Struktur und Organisation analysiert. Dann folgt eine Diskussion über die Organisation der Sexualität bzw. der Instinkte – vom Unbewussten bis zum Ödipuskomplex bei Freud und Lacan – wodurch eine Theorie der Perversion auf der Basis von Ablehnung begründet wird. Ein instruktiver Zugang, bei dem die verschiedenen Punkte von Interesse gut strukturiert sind, wurde gewählt.

Laender NR et al . Perversion – organización o estructura?

Este trabajo intenta discutir la perversión, sus implicaciones en la clínica y algunos de los conceptos clave alrededor de la perversión.

Primero, es analizada la etimología de las palabras Perversión, Estructura y Organización. Despúes sigue una discusión sobre la organización sexual de los instintos- desde lo Inconsciente hasta el complejo de Edipo en Freud y Lacan- planteando las bases para una teoría de la negación-desaprobación de la perversión.

Para organizar mejor los varios aspectos presentados se escogió una aproximación instructiva.
