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.     

Influence of delayed muscle reflexes on spinal stability: Model-based predictions allow alternative interpretations of experimental data

Model-based calculations indicate that reflex delay and reflex gain are both important for spinal stability. Experimental results demonstrate that chronic low back pain is associated with delayed muscle reflex responses of trunk muscles. The aim of the present study was to analyze the influence of such time-delayed reflexes on the stability using a simple biomechanical model. Additionally, we compared the model-based predictions with experimental data from chronic low back pain patients and healthy controls using surface-electromyography. Linear stability methods were applied to the musculoskeletal model, which was extended with a time-delayed reflex model. Lateral external perturbations were simulated around equilibrium to investigate the effects of reflex delay and gain on the stability of the human lumbar spine. The model simulations predicted that increased reflex delays require a reduction of the reflex gain to avoid spinal instability. The experimental data support this dependence for the investigated abdominal muscles in chronic low back pain patients and healthy control subjects. Reflex time-delay and gain dependence showed that a delayed reflex latency could have relevant influence on spinal stability, if subjects do not adapt their reflex amplitudes. Based on the model and the experimental results, the relationship between muscle reflex response latency and the maximum of the reflex amplitude should be considered for evaluation of (patho) physiological data. We recommend that training procedures should focus on speeding up the delayed reflex response as well as on increasing the amplitude of these reflexes.     

Increased forefoot loading is associated with an increased plantar flexion moment

The aim of this study was to identify the cascade of effects leading from alterations in force generation around the ankle joint to increased plantar pressures under the forefoot. Gait analysis including plantar pressure measurement was performed at an individually preferred and a standardized, imposed gait velocity in diabetic subjects with polyneuropathy (n = 94), without polyneuropathy (n = 39) and healthy elderly (n = 19). The plantar flexion moment at 40% of the stance phase was negatively correlated with the displacement rate of center of pressure (r = ?.749, p < .001 at the imposed, and r = ?.693, p < .001 at the preferred gait velocity). Displacement rate of center of pressure was strongly correlated with forefoot loading (r = ?.837, p < .001 at the imposed, and r = ?.731, p < .001 at the preferred gait velocity). People with a relatively high plantar flexion moment at 40% of the stance phase, have a faster forward transfer of center of pressure and consequently higher loading of the forefoot. This indicates that interventions aimed at increasing the control of the roll-off of the foot may contribute to a better plantar pressure distribution.     

Tales of two self-control scales: Relations with Five-Factor and HEXACO traits

This study compared the Five-Factor and HEXACO personality correlates of two common self-control constructs – Tangney self-control and Grasmick self-control – and their relations with delinquency. In both a student and a community sample, conscientiousness (mainly the prudence facet) was the most consistent and strongest correlate of both constructs. HEXACO honesty–humility was an important correlate of Grasmick self-control but not of Tangney self-control. Additionally, honesty–humility (mainly the fairness facet) was the most consistent predictor of delinquency, whereas the two self-control scales differed in the extent to which they predicted delinquency across samples.     

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.     

Hacia una historia del psicoanálisis

RESUMEN

El autor comienza señalando que la comprensión histórica del psicoanálisis exige un tratamiento plural, cuyo enfoque ilumine las diferentes perspectivas -así como su mutua interrelación- que han venido ilustrando su peculiar entidad. Por ello en este trabajo define de forma sistemática los principales enfoque históricos de los que es susceptible el fenómeno psicoanalítico: analítico-biográfico, socio-cultural, institucional-profesional y epistemológico, señalando los principales intereses temáticos y problemas que incluye cada uno y ofreciendo una selección de fuentes bibliográficas según tres criterios combinados: el mantenimiento de las obras clave clásicas, el carácter contemporáneo de las fuentes y el acceso a las mismas.     

El constructo ansiedad en Psicología: una revisión

RESUMEN

Se trata en este artículo de dar una visión sucinta y comprensiva del tratamiento que, desde el ámbito de la Psicología científica, ha recibido el tema de la ansiedad. Casi todas las escuelas, tanto clínicas como experimentales, han intentado dar una explicación, cada cual con su método y de sus principios teóricos a este complejo fenómeno. Aquí se analizarán cuatro enfoques: Psicodinámica y humanística; Experimental motivacional; Psicométrico-factorial; Cognitivo-conductual. También se presenta, al final, de modo sintético, un resumen que trata de integrar las diferentes aportaciones que se han producido en el desarrollo del estudio científico del tema ansiedad.     

Nuevas perspectivas del procesamiento de información

RESUMEN

La Psicología Cognitiva es una de las áreas más pujantes de la Psicología actual. Pese a lo fructífero de esta nueva rama de la Psicología, es necesario formular algunas críticas a este enfoque. Este será el tema principal del presente artículo. Las críticas estarán centradas en las llamadas “analogías formales”. Cuando un dominio de fenómenos es difícil y confuso para nuestra compresión, una solución lícita es establecer algún tipo de analogía entre ese dominio y otro dominio que conocemos mejor. Lo que hemos denominado analogías formales sirven de elementos de vertebración teórica de los datos psicológicos pero, por otra parte, mue stran debilidades importantes. Las principales analogías de la Psicología Cognitiva serán analizadas en este artículo mostrando sus debilidades más importantes.
