Estrategias de decisión de un jurado bajo condiciones de simulación

Resumen

El objeto de esta investigación es analizar el proceso de decisión de un jurado bajo condiciones de simulación. A través de dos experimentos en que se manipula la forma de presentación de la información, se estudian los efectos de la regla de decisión y de las instrucciones en el veredicto y los efectos de la deliberación. Se defiende la hipótesis de que la regla de decisión y las instrucciones tienen respectivamente efectos informativos y normativos sobre el veredicto, y que la deliberación tiene efectos informativos. Estos efectos, sin embargo, sólo resultan parcialmente evidentes en el contexto de una estrategia de juicio compensatoria que supone el procesamiento analítico de la evidencia aportada en el juicio. Los resultados muestran que los sujetos cambian de estrategia cuando cambia la forma de presentación y el tipo de respuesta solicitada que es holística, de elección y no compensatoria en la presentación simultánea y analítica, de juicio y compensatoria en la presentación secuencial. Sólo cuando la deliberación supone un cambio de estrategia tiene un efecto sobre el veredicto que es más favorable que lo que lo era inicialmente para el acusado. Los resultados parecen adecuarse a un modelo de acumulación de evidencia que afecta a la evaluación de los ítems incriminatorios del caso.     

Génesis de la conciencia racial: un estudio sobre identificación y actitudes hacia el color de piel en niños de tres a once años

Resumen

En este artículo exponemos un estudio con 504 niños españoles de 3 a 11 años cuyo objetivo ha sido identificar las primeras manifestaciones de conciencia étnico-racial y su dsarrollo en la infancia, un problema abordado por multitud de investigadores en diversos países, desde décadas atrás (Aboud, 1988, Milner, 1984), pero nuevo en el nuestro. Abordamos el estudio con un enfoque metodológico relativamente diferente de los clásicos. Diseñamos una entrevista semiestructurada con material pictórico y preguntas para obtener información sobre la orientación de los niños hacia el color de piel de las personas (sus preferencias, rechazos y su propia identificación), considerando tanto sus conductas de elección como las justificaciones que proporcionan.

Nuestros resultados revelan: a) relaciones curvilíneas entre edad y preferencia por el propio color de piel, y entre edad y rechazo a la figura de color negro. Hacia los 6–7 años, la orientación de los niños es marcadamente pro-blanco y anti-negro. A partir de los 9 años, se modifica no tanto el porcentaje de rechazo a otros grupos, sino los argumentos que ofrecen. b) En cuanto a la identificación del propio color de piel, hay una relación lineal entre ésta y la edad. No obstante, se observa un amplio desfase entre lo que parece ser una idntificación correcta del propio color (hacia los 5 años) y la toma de conciencia explícita de ese criterio (8 años). Los resultados se comparan con los de otros autores y se discuten en términos de fases en la toma de conciencia étnico-racial (Piaget, 1974, Karmiloff-Smith, 1992).     

Toward a Theory of Progressive Evolution (Large-Scale Stages of Evolutionary Progress)

Here I discuss the basic elements, major stages, and completion of progressive evolution. The cosmic world of self-realization is based on extensive self-development within a closed contour: temporal counter-transitions of spatial counter-elements (energy bonds and media and, basically, substance structures) form of local worlds within it through evolution of informational structures.

• The organic world of reproduction develops through the open informational path: the initial substance, through energy exchange and metabolism, reproduces similar substance; the latter interacts with the environment and, subsequently, reproduces its like, and so on.

• The animal world of self-regulation builds up a closed informational contour in the environment through the informational input and command output.

• The human world of self-cognition forms the intensive type of development within the internal closed informational contour of cognition. Counter-transitions of ideal images and signs relate to their real prototypes. In the course of cognition, abstractive thinking develops and brings man to the possibility of reflection of the initial world in its integrity (thus, elevates man to the infinite, by Hegel).

     

Influencing and adjusting in daily emotional situations: A comparison of European and Asian American action styles

Emotions are for action, but action styles in emotional episodes may vary across cultural contexts. Based on culturally different models of agency, we expected that those who engage in European-American contexts will use more influence in emotional situations, while those who engage in East-Asian contexts will use more adjustment. European-American (N=60) and Asian-American (N=44) college students reported their action style during emotional episodes four times a day during a week. Asian Americans adjusted more than European Americans, whereas both used influence to a similar extent. These cultural differences in action style varied across types of emotion experienced. Moreover, influencing was associated with life satisfaction for European Americans, but not for Asian Americans.     

A Research Inquiry into Some American Women's Sexual Concerns and Problems

Abstract

The New View of Women's Sexual Problems is supported by findings of the 1993-94 Ellison/Zilbergeld sexuality survey of 2,632 mostly white, college-educated women born 1905-1977 (Ellison, 2000; see questionnaire at www.womenssexualities.com). Sexual experiences of women with previous year sexual partners are reported. The most important sexual concerns or problems in the previous year of 1,637 women are categorized: 34% desire/frequency (low sexual desire, desire discrepancy); 28.5% physical responsiveness (female arousal, orgasm; male partners' erectile difficulties, ejaculatory control); 16% lovemaking (sexual technique); 7.5% finding a partner; < 5% sexual relationship, fertility, pregnancy, STDs/safe sex, the woman's body/health, non-monogamy, orientation; 547 others reported none. Exemplary quotes from respondents are included. Sex therapy for low sexual desire is addressed. Recommended solutions emphasize individual differences and the multidimensionality of sexuality.     

Fitting In and Feeling Good

Abstract

This study examined self-evaluation (self-esteem, perceived physical attractiveness, and perceived social competence) and indicators of psychological stress (physical and somatic symptoms of depression and substance use) among 463 adolescent biracial girls from three different backgrounds: Black-White, Hispanic-White, and Asian-White. Patterns of self-evaluation and psychological stress were examined as a function of both parentage and self-identification as either White or non-White. Biracial girls were compared with nonbiracial girls on all variables. Results indicated that outcomes vary as a function of parentage and ethnic self-identification and that there is broad variability among biracial girls from different backgrounds.     

The Call of the Wild Woman

Abstract

Women have a longstanding and unique connection to healing and health care. The feminine perspective, however, has been discounted and decimated through the last 600 years. Now general social and political changes, as well as increasing numbers of women practitioners in health and mental health, are leading to a re-emergence of the feminine perspective in addressing women's needs and in providing health care. This paper traces some of the elements in the history of women and their influences on present day models of health care. It emphasizes women's roles as healers, as patients and as crafters of a new synthesis of health care delivery in the 21st century.     

Impact of intention on the ERP correlates of face recognition

The present study investigated the impact of study-test similarity on face recognition by manipulating, in the same experiment, the expression change (same vs. different) and the task-processing context (inclusion vs. exclusion instructions) as within-subject variables. Consistent with the dual-process framework, the present results showed that participants performed better on the inclusion task than on the exclusion task, with no response bias. A mid-frontal FN400 old/new effect and a parietal old/new effect were found in both tasks. However, modulations of the ERP old/new effects generated by the expression change on recognized faces differed across tasks. The modulations of the ERP old/new effects were proportional to the degree of matching between the study face and the recognition face in the inclusion task, but not in the exclusion task. The observed modulation of the FN400 old/new effect by the task instructions when familiarity and conceptual priming were kept constant indicates that these early ERP correlates of recognition depend on voluntary task-related control. The present results question the idea that FN400 reflects implicit memory processes such as conceptual priming and show that the extent to which the FN400 discriminates between conditions depends on the retrieval orientation at test. They are discussed in relation to recent controversies about the ERP correlates of familiarity in face recognition. This study suggests that while both conceptual and perceptual information can contribute to the familiarity signal reflected by the FN400 effect, their relative contributions vary with the task demands.     

Investigation of effects of face rotation on race processing: An ERPs study

Recent ERP research has indicated that the processing of faces of other races (OR) and same race (SR) as the perceiver differs at the perceptual level, more precisely for the N170 component. The purpose of the present study was to continue the investigation of the race-of-face processing across multiple orientations. Event-related brain potentials (ERPs) and performance were recorded when Caucasian participants were required to categorize by race Caucasian and African faces presented in eight different angles of orientation. Three main observations were made: (1) the face-sensitive N170 is modulated by the race of faces, being larger in response to OR compared to SR faces; (2) face rotation affected this component in the same pattern for both racial groups; (3) the N170-ORE progressively disappeared as the faces moved away from their canonical orientation at the right hemisphere only. Thus, the current findings suggest that configural/holisitic information is extracted from faces of both racial groups, but that upright OR faces require increased demands.     

Parents as Social Skills Trainers and Evaluators of Children

This study evaluated the effects of a 4-week group parent training program on parents' conceptual knowledge regarding social skills and perceptions of their children's social competence and psychosocial adjustment. It also examined the concordance prior to parent training between the parent measures and independent sociometric measures of children's acceptance by peers. Participants were 79 normal children enrolled in second grade and 45 parents. A group pretest-posttest design compared experimental and wait-list control parent groups before and after parent training for the experimental group. Parent training produced a significant effect in parents' conceptual knowledge and perceptions of children's social skills over time, and follow-up assessment 6 weeks later suggested maintenance of training effects. Psychosocial adjustment levels were within the normal range before and after treatment. Correlational analyses between parent measures and peer acceptance ratings indicated significant positive relationships between parents' and peers' perceptions on most measures. The findings support the potential value of parents as trainers and evaluators in programs to enhance children's social skills.
