Anticipación semántica e interferencia de tipo Stroop en tareas de denominación de palabras

Resumen

Una relación semántica entre los componentes de estímulo relevantes e irrelevantes facilita la ejecución en tareas de anticipación pero parece inhibir la ejecución en tareas de tipo Stroop. Se estudiaron las causas de esta discrepancia. En una serie de tareas de denominación de palabras, se analizaba el efecto del número de dominios semánticos (que covariaba con el número de alternativas de respuesta) presentando a un grupo de estudiantes un conjunto idéntico de estímulos en forma bloqueada o mixta. El experimento 1 muestra que la presentación bloqueada produce un efecto de interferencia de tipo Stroop, mientras la presentación mixta produce facilitación semántica. Los experimentos 2 y 3 muestran que la variante palabra-palabra de la tarea de Stroop y la variante denominación de palabra de la tarea de anticipación semántica pertenecen a una misma familia de tareas. Ambas tareas muestran: a) un efecto de facilitación cuando el anticipador se relaciona con el objetivo y b) un efecto de interferencia cuando el anticipador es miembro del conjunto de respuesta. En la tarea de Stroop, la competición de respuestas aumenta el efecto de facilitación; en la tarea de anticipación, el efecto de facilitación semántica aumenta el efecto de competición de respuestas.     

Paternal Postnatal and Subsequent Mental Health Symptoms and Child Socio‐Emotional and Behavioural Problems at School Entry

Research on the effect of paternal mental health problems, particularly on young children, is based predominantly on clinical levels of depression. Furthermore, potential mediators such as marital discord have often been overlooked. This longitudinal community study assessed the association between paternal mental health symptoms in a community sample (N = 705) assessed at 3 months postnatally (Edinburgh Postnatal Depression Scale) and 36 months (General Health Questionnaire) and children's socio‐emotional and behavioural problems at 51 months (Strengths and Difficulties Questionnaire) as reported by mother, father and teacher. Controlling for socioeconomic status and maternal mental health symptoms at 3 and 36 months, paternal postnatal depressive symptoms predicted more father‐reported child problems at 51 months but, in contrast to previous findings, not mother‐reported problems. Paternal mental health symptoms at 36 months predicted both maternal and paternal reports of child problems at 51 months controlling for both paternal and maternal postnatal symptoms. Paternal mental health symptoms at 3 and 36 months were not significant predictors of teacher‐reported child problems. Postnatal marital discord and paternal mental health problems at 36 months both mediated the relationship between paternal postnatal symptoms and later child emotional and behavioural problems. Child gender did not moderate the relationship. Implications for interventions are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Testing Posttraumatic Stress as a Mediator of Childhood Trauma and Adult Intimate Partner Violence Victimization

This study examined whether potential posttraumatic stress disorder (PTSD) mediated the relationships between different forms of childhood trauma (sexual abuse, physical abuse, violence between caregivers) and intimate partner violence (IPV) victimization (psychological, physical, sexual). Participants were 1,150 female nurses and nursing personnel. Path analytic findings revealed potential PTSD partially mediated the relationships between childhood sexual abuse and psychological IPV and childhood sexual abuse and sexual IPV. Potential PTSD did not mediate the relationship between other types of childhood trauma and IPV. This study adds to the literature indicating PTSD as a risk factor for revictimization in the form of adult IPV among women. Screening for and treatment of PTSD among female child sexual abuse survivors could prevent future IPV victimization.     

Social Capital, Social Networks, and Political Participation

Social Capital is created through the patterns of interdependence andsocial interaction that occur within a population, and we attempt to understand the participatory consequences of these patterns relative to the effects of human capital and organizational involvement. The production of social capital in personal networks was examined with the use of social network and participation data from the 1992 American study of the Cross National Election Project. The results suggest that politically relevant social capital (that is, social capital that facilitates political engagement) is generated in personal networks, that it is a by-product of the social interactions with a citizen's discussants, and that increasing levels of politically relevant social capital enhance the likelihood that a citizen will be engaged in politics. Further, the production of politically relevant social capital is a function of the political expertise within an individual's network of relations, the frequency of political interaction within the network, and the size or extensiveness of the network. These results are sustained even while taking account of a person's individual characteristics and organizational involvement. Hence, the consequences of social relations within networks are not readily explained away on the basis of either human capital effects or the effects of organizational engagement.     

New frameworks for careers guidance: developing a conceptual model of the interview

Recent research has highlighted limitations in our understanding of the dynamics occurring within the careers guidance interview. A study was conducted of how the client and practitioner engage in the exchange within the interview and how meanings are negotiated and received by each of the participants. The objectives for the study were to examine a sample of guidance interviews in order to: (i) identify which interventions by practitioners are perceived as helpful and unhelpful by clients and practitioners; (ii) establish how helpful and unhelpful interventions relate to change in understanding; and (iii) compare and contrast the identification and commentaries by practitioners and clients. The results showed that practitioners reported significantly more helpful interventions than clients and that there was limited agreement in the identification of interventions. Three thematic categories were derived to group the helpful interventions. This analysis provided the basis for the development of a conceptual model of the interview. Further research to test the model and assess its potential to inform careers guidance training and practice is outlined.
