Rape impact: Immediately and two months later

This paper analyzes assault victims’ reactions over the course of two months. Specifically, reaction types are analyzed across four dimensions: behavioral changes, interpersonal difficulties, physical symptoms, and emotional responses. Initially, most rape victims report fairly high levels of disruption across three of the four reaction types, with some signs of recovery two months later. Patterns of reactions are also exhibited. At the two month follow‐up, behavioral changes, physical symptoms, and emotional responses have declined, while interpersonal difficulties have increased slightly. These data suggest that the present service delivery system of the rape crisis center may be problematic in that they offer only short‐term intervention. Some victims of rape may require a different type of service from such centers.     

Understanding the Lived Experience of Formerly Homeless Adults as They Transition to Supportive Housing

The researchers conducted in-depth interviews with formerly homeless adults who had moved to supportive housing to understand their perceived occupational needs and the factors that affected their transition. A qualitative research design with four participants who had a history of substance abuse and mental illness was used. Participant interviews that addressed categories of daily living and personal satisfaction produced data that were coded for analysis using conventional content analysis. Mega themes emerged that related to factors shaping the housing transition and maintenance experience. Occupational therapists can use these findings to create informed interventions to enhance this population's occupational performance.     

Biomechanical and energetic determinants of technique selection in classical cross-country skiing

Classical cross-country skiing can be performed using three main techniques: diagonal stride (DS), double poling (DP), and double poling with kick (DK). Similar to other forms of human and animal gait, it is currently unclear whether technique selection occurs to minimize metabolic cost or to keep some mechanical factors below a given threshold. The aim of this study was to find the determinants of technique selection. Ten male athletes roller skied on a treadmill at different slopes (from 0° to 7° at 10 km/h) and speeds (from 6 to 18 km/h at 2°). The technique preferred by skiers was gathered for every proposed condition. Biomechanical parameters and metabolic cost were then measured for each condition and technique. Skiers preferred DP for skiing on the flat and they transitioned to DK and then to DS with increasing slope steepness, when increasing speed all skiers preferred DP. Data suggested that selections mainly occur to remain below a threshold of poling force. Second, critically low values of leg thrust time may limit the use of leg-based techniques at high speeds. A small role has been identified for the metabolic cost of locomotion, which determined the selection of DP for flat skiing.     

Rushton: The great theoretician and his contribution to personality

J. Philippe Rushton has been described as one of the greatest theorists in the field of personality and individual differences and social psychology. His life history theory (Differential K Theory) was said to bring unification to the scientific study of racial differences as Einstein’s theory of relativity unified the field of physics. It was maintained that Rushton’s General Factor of Personality (GFP) meshes with both general intelligence and his Differential K Theory. The present author presented a two-pillar theory of adaptive functioning that has a heavy concentration on Rushton conceptualization.     

Executive functioning moderates the relationship between motivation and adolescent depressive symptoms

We investigated the association between adolescent depressive symptoms and components of executive functioning (EF), including planning (Tower of London), set-shifting (Wisconsin Card Sorting Task), and inhibition (Stop Signal Task) in a community sample of 12–14 year olds. Further, EF was tested as a moderator of motivation (as operationalized by revised Reinforcement Sensitivity Theory) effects on depressive symptoms. Results suggested that planning ability was associated with depressive symptoms. Furthermore, planning ability moderated the relationship between motivation (fight-flight–freeze system; FFFS) and depressive symptoms, such that among adolescents with poor planning ability the FFFS positively predicted depressive symptoms, but among adolescents with strong planning ability the FFFS negatively predicted depressive symptoms. Neither set-shifting nor inhibition were associated with depressive symptoms. Findings highlight the need to consider multiple components of EF and to integrate motivational and executive dysfunction models to the study of depression.     

Esfuerzo y decremento de vigilancia en tareas de discriminación sucesiva y simultánea

Resumen

El objetivo del experimento presentado en este artículo fue probar la hipótesis de que el decremento de sensibilidad en tareas de atención sostenida, ocurre porque los recursos atencionales o esfuerzo que demanda la tarea no pueden matenerse durante un tiempo prolongado. Comparamos dos tareas que diferían en carga de memoria y registramos tres grupos de índices de esfuerzo o gasto atencional: rendimiento en una tarea secundaria concurrente, esfuerzo subjetivo y actividad cardiovascular (IBI medio y amplitud espectral del componente 0.10 Hz). En ambas tareas observamos un declive significativo a lo largo del tiempo en eficiencia o ritmo de procesamiento, indicado por la razón entre la precisión y la velocidad. Los datos acerca del esfuerzo subjetivo y el rendimiento en la tarea secundaria no parecen apoyar la hipótesis original. El principal hallazgo fue que la actividad cardiovascular al comienzo de la tarea, medida por la amplitud del componente 0.1 Hz, era un predictor significativo del decremento de eficiencia en ambas tareas de vigilancia. Si esta amplitud es un índice fisiológico fiable de atención, nuestro resultado sugiere que un procesamiento controlado, con esfuerzo, al comienzo de la tarea previene el decremento de vigilancia.     

Entrevista a Urie Bronfenbrenner

RESUMEN

Urie Bronfenbrenner comienza repasando su biografía y explicando la influencia de figuras como Kurt Lewin, Tolman o sus propios padres en su formación científica. A continuación se ocupa de los problemas metodológicos de la investigación en Psicología, sus estudios incorporando el modelo “persona-proceso-contexto” o los trabajos de laboratorio, centrándose en diversas reflexiones en torno a la perspectiva ecológica y la consideración del ambiente. Además el autor adelanta algunos conceptos de su último trabajo todavía inédito, como el factor tiempo o la relevancia del sistema de creencias para comprender el desarrollo. Finalmente aborda su vinculación a programas de intervención social y comunitarios y aporta algunas ideas acerca del futuro de la psicología europea y española.     

Chaotic attractors in the therapeutic system 1

Because little research had been done on the presence and role of latent communication in the context of team‐conducted family therapy, the writers set out to monitor unconscious responses generated under these conditions. Specifically, they investigated an ongoing family treatment situation conducted according to the “reflecting team model.” One team of therapists handles the actual treatment session, while the other observes from behind a one‐way mirror. During the course of a session, the second team makes suggestions to the treatment team either by telephone or by calling the therapists out of the treatment room.

As the project developed, the writers found that the unconscious responses of both family and treatment teams indicated a process at work beyond the conscious intentions of the participants. That is, the therapeutic enterprise was functioning as a dynamical system, whose increasing complexity suggested a self organizing principle at work. This paper traces the development of the system's movement toward greater complexity, identifies the specific interventions that indicate this process, describes how all participants demonstrated a high degree of resonance and synchronization with this overarching‐self organizing pattern. This paper serves to alert therapists to the role of unconscious communication within the therapeutic system and postulates that the generation of form within psychotherapy follows many of the same self organizing processes found in other human and non human systems.
