Placebo: Análisis conceptual de un constructo en transición

RESUMEN

Los autores comienzan planteando que las opiniones vertidas en algunas revisiones acerca del constructo placebo son respuestas a la evolución actual hacia el empleo de conceptualizaciones más cognitivas en la psicoterapia. Seguidamente ofrecen un breve repaso histórico de esta noción, para centrarse en sus aspectos denotativos y connotativos. Respecto a los primeros, revisan las dos metáforas dominantes que pueden encontrarse en la literatura: (a) los placebos como ingredientes inertes en vez de activos y (b) como agentes no específicos en vez de específicos. En relación con los aspectos connotativos, examinan las cuatro fuentes de donde proceden y afirman que distinguiendo entre los verdaderos efectos placebo y los artefactos de medida las connotaciones negativas de este constructo son inmerecidas. Seguidamente abordan su utilidad en la evaluación de la eficacia de la psicoterapia y responden a la cuestión de si las terapias actuales son más eficaces que el tratamiento inespecífico. Este trabajo concluye que como el placebo ha de jugar un papel crucial en la evaluación científica de la psicoterapia, rechazarlo prematuramente constituiría una regresión conceptual y metodológica.     

Estudio de las diferencias individuales en gastos atencionales,a partir de una tarea de papel y lápiz

Resumen

En este trabajo, que conjuga la tradición psicométrica con la perspectiva de procesamiento de información, se estudió si las diferencias en rendimiento observadas en los tests están asociados a diferencias individuales en gasto atencional. Fueron seleccionados 4 grupos extremos de sujetos en función de dos factores de inteligencia (verbal y espacial), los cuales realizaron una tarea de verificación de frases (tarea primaria) aisladamente o en conjunción con una de emparejamiento perceptivo (tarea secundaria). Se utilizaron como variables dependientes el número de aciertos de la tarea primaria, en ambas condiciones, y en la tarea secundaria, con tiempo limitado; y el número de errores en ambas tareas, sin límite de tiempo. Los sujetos altos verbales tuvieron más aciertos que los bajos verbales al ejecutar la tarea primaria en solitario, e iguales diferencias se encontraron entre altos y bajos espaciales; no se observaron diferencias en el número de errores. Al realizar ambas tareas concurrentemente, los altos verbales tienen mayor número de aciertos y cometen menos errores, en la tarea primaria, que los bajos verbales; los altos y bajos espaciales se diferencian únicamente en el número de aciertos. Estos resultados son discutidos y comparados con estudios diferenciales recientes.     

Disociaciones entre pruebas implícitas y explícitas de memoria: significado e implicaciones teóricas

Resumen

Las disociaciones entre pruebas implícitas y explícitas de memoria se han convertido últimamente en el fenómeno más rico e ilustrativo teóricamente de que la memoria se manifiesta tanto de una forma directa o explícita como de una forma indirecta o implícita. La distinción entre memoria implícita y explícita ha proporcionado un marco teórico y de trabajo extremadamente fructífero para aumentar nuestro conocimiento sobre la naturaleza y arquitectura de la memoria. En este trabajo se presenta una amplia revisión de las disociaciones entre pruebas implícitas y explícitas de memoria, las múltiples variables que las producen, las distintas poblaciones susceptibles de generarlas y las explicaciones más relevantes sobre su significado. De entre estas explicaciones destacan: 1) la que considera que las disociaciones son el resultado de diferentes procesos y 2) la que entiende que reflejan diferentes sistemas de memoria. Entre los proponentes de ambas explicaciones se ha desarrollado un debate que ha llevado a una nueva concepción de la naturaleza y arquitectura del sistema de memoria que da fundamento a los efectos de priming.     

Nationwide survey of contraceptive and sexually transmitted infection knowledge,attitudes and skills of university students in Portugal

Sexually transmitted infections and (STIs) unintended pregnancies are contemporary public health concerns. Understanding factors (e.g. knowledge, attitudes and skills) influencing sexual behaviours of university students are critical to develop targeted and tailored risk-reduction interventions for this vulnerable population. Thus, the goals of this study were to describe sexual behaviours and analyze differences between genders for sexual behaviours; to identify whether differences exist between genders and age groups regarding knowledge, attitudes and skills concerning contraceptive methods and STIs, and to evaluate the association of knowledge with attitudes and skills with sexual behaviour among university students in Portugal. The sample included 3278 students. Results show that the majority were sexually active and use condoms and oral contraceptives. In general, university students have high knowledge, positive attitudes and skills about contraception and STIs. Gender analyses indicated that women had greater knowledge, and more favourable attitudes, and higher skills toward contraceptive and STI preventive behaviour College students, in particular, face new challenges in sexual health and would benefit from more comprehensive education aimed at promoting healthy decision-making about family planning and STI prevention.     

Tradition,Reason, and Qur’anic Exegesis in the Modern Period: The Hermeneutics of Said Nursi

Key figures in modernist Qur’an exegesis include Sayyid Ahmad Khan (d. 1898) and Muhammad ?Abduh (d. 1905). This article presents the exegetical principles of Bediuzzaman Said Nursi (1877–1960), a Muslim thinker and a major twentieth-century Turkish scholar who is not necessarily to be labelled a ‘modernist’, on tafsīr bi-al-ma?thūr (tradition-based exegesis) and tafsīr bi-al-ra?y (reason-based exegesis) with special reference to the views of early Muslim modernist thinkers. It particularly refers to Nursi’s work on u?ūl al-tafsīr, Mu?ākamāt (Reasonings), and his one-volume commentary, Ishārāt al-i?jāz (Signs of Inimitability), in order to understand his method of tafsīr. The purpose of the article is to place Nursi within the historical framework of Qur’an exegesis and it argues that, while there are some similarities between ?Abduh and Nursi since the latter is influenced by the former, the methodological differences are clear. While ?Abduh’s method is text-based, Nursi’s is based on kalām (Islamic theology). While ?Abduh is critical of the classical style tafsīr and linguistic discussions in tafsīr, Nursi can be considered to be a modern representative of the Ottoman exegetical school and a follower in the way of al-Zamakhsharī (d. 538?1144), Fakhr al-Dīn al-Rāzī (d. 606?1210) and al-Bay?āwī (d. 685/1286).     

Exposing operations of power in supervisory relationships

Through a poststructural lens, we examine how power may show itself in relationships between supervisees and supervisors, producing both helpful and harmful effects. Drawing from our own experiences, as well as conversations with other members of our supervisory group, we demonstrate how privileged discourses around professional status, gender, and race may bring about difficulties including a sense of doubt, worry, inadequacy, and a fear of speaking up. We also illustrate how these difficulties can be addressed in a manner that may lessen their influence, while increasing supervisees' sense of agency.     

FATHER PLAY: IS IT SPECIAL?

Both mothers and fathers play with their children, but research on parent–child play interactions is conducted with mothers three times more often than it is with fathers. The articles in this special issue address this gap by focusing on the nature and quality of father–child play, across cultural contexts, and considering whether father play offers something unique and special for early human development, in infancy or early childhood. The studies show that fathers can be just as developmentally supportive as are mothers in terms of being playful and engaged with their children in ways that are related to greater child socioemotional competence, emotion regulation, and vocabulary, and to less aggression, anxiety, and negativity. We encourage future research to examine the cultural influences, family system dynamics, and specificity of timing and types of father–child play in relation to children's developmental competence.     

The relationship between acceptance,fatigue, and subjective cognitive impairment in hematologic cancer survivors

Background/Objective: Cancer and its treatment can have a detrimental impact on psychological well-being. Acceptance as the basis of acceptance and commitment therapy (ACT) has shown beneficial effects on depression and anxiety. However, its relationship to fatigue and cognitive impairment has not been investigated. A protective effect of acceptance may open up a new target for psychological intervention.Method: A cross-sectional postal survey was undertaken. 922 hematological cancer survivors (≥ 2.5 years post diagnosis) were recruited through two regional cancer registries in Germany. Acceptance (AAQ-II), fatigue (BFI) and subjective cognitive impairment (AFI) were assessed.Results: Higher levels of acceptance were negatively associated with fatigue and subjective cognitive impairment (R²= .34 and R²= .26, respectively). The relationship between fatigue and fatigue-related impairment of daily life was weaker for survivors with high acceptance.Conclusions: Acceptance is strongly associated with fatigue and subjective cognitive impairment. ACT may be useful to reduce symptoms of fatigue and subjective cognitive impairment in cancer survivors.     

The Garden of the Heart and Soul: the image,the way,and the meaning

This paper begins with an explanation of the four Chinese characters that represent the project of the Garden of the Heart and Soul. This project was founded to help the psychological development of orphans, as well as to provide psychological relief for the victims of ecological disasters such as earthquakes through the use of Jungian psychology, sandplay therapy, and the psychology of the Heart. Eleven years after its founding, there are 83 work‐stations on mainland China. The authors discuss how the Chinese characters influenced the way they set up their project and the values that guide them. In addition to helping the individuation of the people they work with, their work provides a container for the collective psyche and a connection with the cultural archetypal roots.
