Psicología del «efecto placebo» y fundamentos para su uso clínico intencionado

Resumen

Este es un trabajo de discusión teórica que indaga sobre la psicología del «efecto placebo» (EP) y las posibilidades de su recuperación clínica. Tiene cuatro partes.

En la primera, se exponen los resultados básicos, conforme a las pautas estándar e inversa en la ocurrencia del EP. En la segunda se revisan críticamente las explicaciones en términos de sugestión y de expectativas-atribución. En la tercera, se desarrolla una teoría interconductual, con particular referencia al condicionamiento, a la farmacología conductual y a los sistemas endorfino e inmunitario.

Finalmente, en la parte cuarta se indican diversas posibilidades teóricas y empíricas para el uso clínico intencionado del EP, tanto en medicina como en psicología clínica.     

A hypothesis on the rhythm of becoming

An archetype of rhythms is set forth which tries to explain, simply and coherently, the quantum discontinuities which take place both in the evolutionary dynamics of the Macrocosmos—universal history—and in the Microcosmos—individual development.

The stationary waves and musical theory give us the key to understand those quantum leaps in the vibrating processes of unfurling and furling between the Nothing and the Whole: the successive 2nd harmonics (1/3) are generating sonorous novelties. This simple scheme fits, with surprising accuracy, all the basic bifurcations that paleontologists, anthropologists, historians and psychologists speak to us about.

It seems to be confirmed then that an emerging hierarchy of order could characterize the processes of the universe. Evolution would then be the temporal unfurling (‘explicate order“) of those intrinsic levels of potential stability of the non‐dual reality (‘implicate order“).     

Psychoanalysis and University in Brazil: Possibilities and Limits of This Articulation

The goal of this article is to clarify some of the aspects concerning the academic teaching and research that is carried out in the field of psychoanalysis in the Brazilian Universities, versus the transmission and training in psychoanalytic institutions. The author describes how psychoanalysis is present in the Brazilian university context, from undergraduate to graduate studies, and also points out perspectives regarding the future of psychoanalysis in Brazil.     

Breach of Psychological Contract and the Development of Burnout and Engagement: A Longitudinal Study Among Soldiers on a Peacekeeping Mission

We assumed that a breach in psychological contract had an effect on soldiers' well-being and not only promoted their burnout levels but decreased their levels of engagement. In a longitudinal study with 387 individuals on a peacekeeping mission, we analyzed the impact of the noncompliance of Army obligations in this mission on the burnout and engagement of soldiers. We found that during the mission their levels of burnout increased, whereas their engagement levels dropped. At the end of the mission, however, this breach in psychological contract did not influence their burnout levels, in spite of a continued reduction in the soldiers' engagement. Theoretical and practical implications are discussed and limitations and suggestions for future research are presented.     

Relational Job Characteristics and Work Engagement: Mediation by Prosocial Motivation

This study tested the relation between perceived social impact, social worth, and work engagement in the military, and mediating effects of prosocial motivation. We tested hypotheses using structural equation modeling analysis in a field study with 322 officers and sergeants and 1,045 soldiers of the Portuguese Army. Results confirmed that perceived social impact and social worth were associated with work engagement. Furthermore, regardless of the rank category, perceived social impact was associated with higher prosocial motivation, which in turn was associated with higher work engagement. In the soldiers subsample, results further indicated that soldiers’ perceived social worth was associated with higher prosocial motivation, which in turn was related to higher work engagement. The direct effects of perceived social impact and social worth on work engagement, and the mediating role of prosocial motivation supported the hypothesis that perceptions of social impact and social worth may strengthen the motives to “do good” (prosocial motivation), leading to an upward spiral that cultivates work engagement among members of the military.

Dissociative Experiences and Creativity in Fine Arts Students

Studies on creative personality have revealed that the relationship between personality and creativity remains unclear, and various types of creative thinking have been have been associated with various personality traits. To assess the influence of dissociative experiences on creativity in the context of fine arts education, in which the creative process plays a key role, a sample of fine arts students received a test of creative potential and the dissociative experiences test. The results revealed significant differences in creativity (creative imagination and creative experiences) between students scoring high or low in the number of dissociative experiences. High dissociative experiences scores were associated to high scores in creative imagination and creative experiences, and low scores in dissociative experiences were inversely related to creative imagination and creative experiences. Further studies are required to corroborate these findings.     

Psychological distance and reaction time in a Stroop task

Several sources of interference may simultaneously affect the onset of the well-known “Stroop effect.” Among them is the semantic component, which is reflected in the gradient or semantic effect. This effect consists of an increase in the amount of interference as the semantic distance between the word and the color concept decreases. Shepard (Science 237:1317–1323, 1987) relates psychological space, measured through multidimensional scaling, to mean response times. The present investigation aims to study the function relating the semantic gradient with the psychological distance between the word and the color in a Stroop task. After measuring the gradient, we obtained the subjective rating of the degree of dissimilarity of the gradient words with the concept of “color.” In our work, we show that the amount of interference in a Stroop task increases when the semantic distance from the word to the color concept decreases, and it does so exponentially. We replicated the study with different stimuli to test the robustness of the results.     

Being ‘Spiritual’ and Being ‘Religious’ in Europe: Diverging Life Orientations

The present study shows that being ‘spiritual’ and being ‘religious’ are becoming different life orientations for a large part of the population. As far as we know, for the first time, a sample from an European country shows that these orientations are reflected in two coherent clusters of beliefs, experiences, and practices of what we call ‘new spirituality’ on the one hand and ‘traditional, church-related religion’ on the other hand. In addition, it appears that ‘only spiritual’ (and not ‘religious’) people and ‘only religious’ (and not ‘spiritual’) people have less ‘intensive’ spiritual/religious lives than people who describe themselves as ‘both spiritual and religious’. The ‘both’ category is not homogenous, probably as a result of the different associations which its members have of the conceptions of ‘spiritual’ and ‘religious’. The people in this category can be sub-divided in two sub-groups which show different profiles.     

Is service climate strength beneficial or detrimental for service quality delivery?

This study examines whether climate strength has a direct, moderating, or curvilinear effect in the relationship between service climate and customer service quality perceptions. To this end, we carried out cross-sectional and lagged empirical studies in the Spanish hospitality sector. Our cross-sectional results confirmed that high climate strength in managerial practices fosters a positive impact of managerial practices on customer service quality evaluations. However, other results related to customer orientation of services question the idea that service climate strength is always a precursor of service quality. High climate strength in customer orientation enhanced the negative relationship between customer orientation and functional service quality in a cross-sectional study, and between customer orientation and relational service quality in a lagged study. In addition, an examination of curvilinear effects of climate strength revealed an inverted U-shaped relationship between climate strength in customer orientation and relational service quality over time. The article concludes with a discussion of these results.
