La tarea de seguimiento en el estudio de la atención selectiva

Resumen

La utilización de la tarea de seguimiento en el estudio de la atención selectiva, ha dado lugar a un gran número de resultados confusos y contradictorios que han influido en el mantenimiento de la controversia sobre el problema de la selectividad.

El objetivo del presente artículo fue analizar algunos factores responsables de esta discrepancia experimental: 1. Problemas metodológicos asociados con los estudios de seguimiento.

2. Variables relacionadas con la tarea de seguimiento cuya influencia no ha sido tomada en cuenta en la literatura.

3. Concepciones teóricas extremas sobre la atención selectiva.

El análisis realizado sugiere un replanteamiento de los problemas de selectividad y capacidad, donde se cuestione la dicotomia selección anterior/posterior y en su lugar se asuman concepciones más flexibles del proceso atencional.     

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.     

Comunicación simultánea: un modelo para enfrentar los déficit lingüísticos del niño autista

Resumen

El empleo de procedimientos de comunicación simultánea, en el tratamiento de los niños autistas, es una de las vías más prometedoras para incrementar la competencia comunicativa de estos niños. En este articulo se revisan los resultados del tratamiento de dos niños autistas con métodos de comunicación simultánea y las implicaciones de este método para el tratamiento de los niños autistas.     

Understanding Hope. Persons in the Process of Dying

Changes both within the profession of psychoanalysis and in society as a whole have affected our psychoanalytic training programs and presented new ethical challenges. Whereas in earlier decades training programs needed to be concerned primarily about the inviolability of the training analysis and the choice of appropriate analytic candidates, today there is little support for psychoanalysis as a treatment modality. Institutes are experiencing greater competition in attracting quality candidates and in providing them with adequate training experiences. This strain encourages institutes to operate in unethical ways to attract candidates. On the other hand, within the profession itself we are experiencing much theoretical ferment and the increasing feminization of the profession. These changes are affecting our training institutes and our ethical values in both positive and negative ways.     

Performance in Autobiographical Memory of Older Adults with Depression Symptoms

The aim of this study was to compare the performance in the Autobiographical Memory Test in older adults with high scores on depression symptoms (HDS) compared with a matched group with low scores on depression symptoms (LDS) according to the clinical cut‐off of the Centre for Epidemiological Studies Depression Scale. Participants were asked to generate specific autobiographical memories in response to a series of positive and negative cue words. Latencies of responses for each item were also scored. LDS participants showed a higher proportion of specific memories than HDS participants. Latencies of responses to positive and negative cues were greater for HDS than LDS. Specific autobiographical memory was positively associated with Life Satisfaction. Cognitive emotional changes in the function of memory with age are suggested as a possible explanation for the findings. Copyright © 2012 John Wiley & Sons, Ltd.     

Contribution of parents' adult attachment and separation attitudes to parent‐adolescent conflict resolution

This study examined the contribution to parent‐adolescent conflict resolution of parental adult attachment styles and attitudes toward adolescent separation. Questionnaires were completed by 295 couples with early to late adolescent children. Structural equation models were used to test self and partner influences on conflict resolution for three attachment orientations: confidence (model A), anxiety (model B) and avoidance (model C). Model A showed self influences between parents' confidence orientation and negotiation and also via positive attitudes towards separation. Also, the fathers' use of negotiation was facilitated by the mothers' confidence orientation and vice versa, indicating partner influences as well. Model B showed self influences between parents' anxiety orientation and the use of dominance and withdrawal and also via negative attitudes towards separation. Model C showed self influences between parents' avoidance orientation and dominance and withdrawal, and a partner influence between fathers' avoidance and mothers' use of dominance. The results indicated that the parents' adult attachment system and the parenting system were related in the area of conflict resolution, and that self influences were stronger than partner influences.     

Race,Immorality and Money in the American Baha'i Community: Impeaching the Los Angeles Spiritual Assembly

This article analyses the dissolution of the Baha'i local assembly of Los Angeles in 1986–88 by the National Assembly. Official explanations for this move focused on lapses in morality and administrative discipline, but local interviewees, as well as some official pronouncements, suggest that the conflict had two roots: the globalisation of the community and resultant ethnic conflict among whites, African–Americans and newly immigrant Iranians; and national/local conflicts over power and money. Low-information elections, the unaccountability of elected officials, censorship and difficulties in acknowledging social conflict were the causes of these episodes in the Baha'i religion.     

Inhibition: Mental Control Process or Mental Resource?

The current study tested 2 models of inhibition in 45 children with language impairment and 45 children with normally developing language; children were aged 7 to 12 years. Of interest was whether a model of inhibition as a mental-control process (i.e., executive function) or as a mental resource would more accurately reflect the relations among mental-attentional (M) capacity, inhibition, updating, shifting, and language competence. Children completed measures of M-capacity (in the verbal and nonverbal domains), inhibition, updating, shifting, and language. Path analyses showed the data provided a poor fit to the model of inhibition as a mental-control process but a good fit to the model of inhibition as a mental resource. Results are consistent with the theory of constructive operators and suggest inhibition is a mental resource rather than a mental-control process.     

Two-and-a-Half-Year-Olds’ Memory for Sources of Actions: Contextual Support Facilitates Recall

This research examines the early emergence of source-monitoring abilities. Previous research has consistently demonstrated that children as young as 3 to 4 years of age do well on simple versions of action-based source-monitoring tasks. Research on even younger children, however, remains lacking. In this study we examined whether 2½-year-olds could accurately recall source on a simplified task. For the procedure, we used an action-based task in which children collaborate with an experimenter to build a model farm. During construction, the child and the experimenter took turns placing items on the farm. After construction, children were administered a source memory test in which they were asked to recall who had placed each item. To more closely examine factors that influence source accuracy in this young population, we included two conditions that varied in terms of contextual support. In the no-context-cues condition, in line with typical source-monitoring tasks, children were asked the source test question while items were presented individually and the farm was not in view. In the context-cues condition, the original spatial array of farm items was left intact to provide additional cues for children's source decisions. The main finding was that children in both conditions showed high levels of source accuracy at test indicating a surprisingly early age of emergence for this ability. Also, as predicted, children in the context-cues condition were the most accurate in attributing source.
