Attentional network task performance in schizophrenic patients

Several studies have researched the attentional functioning of schizophrenic patients by means of the Attentional Network Test. The present work reviews these studies and assesses the clinical relevance of their results. Both the reviewed data and our own results suggest that the Attentional Network Test does not provide a clear-cut discrimination of the attentional profile of schizophrenic patients from a clinical point of view. However, after classifying patients according to their psychotic symptoms, it became evident that positive syndrome patients are less efficient at tasks that tap the orientation network.     

Ecumenism and Evangelicalism: Where Are We?

While the ecumenical movement, and particularly the World Council of Churches, must always be an inclusive forum where the richness of the total life of the Christian church is manifest, this article argues that evangelicals cannot give up the quest for church unity because that would mean ignoring a central aspect of the prayer of Jesus Christ. Looking at areas of convergence between the evangelical and the ecumenical movement, four areas are identified for further cooperation and dialogue: the authority of the Bible; mobilizing all churches for the evangelization of the whole world; the perspective of the poor; and the challenge of justice and peace.     

A Network Approach for Evaluating Coherence in Multivariate Systems: An Application to Psychophysiological Emotion Data

We present an approach for evaluating coherence in multivariate systems that considers all the variables simultaneously. We operationalize the multivariate system as a network and define coherence as the efficiency with which a signal is transmitted throughout the network. We illustrate this approach with time series data from 15 psychophysiological signals representing individuals’ moment-by-moment emotional reactions to emotional films. First, we summarize the time series through nonparametric Receiver Operating Characteristic (ROC) curves. Second, we use Spearman rank correlations to calculate relationships between each pair of variables. Third, based on the obtained associations, we construct a network using the variables as nodes. Finally, we examine signal transmission through all the nodes in the network. Our results indicate that the network consisting of the 15 psychophysiological signals has a small-world structure, with three clusters of variables and strong within-cluster connections. This structure supports an effective signal transmission across the entire network. When compared across experimental conditions, our results indicate that coherence is relatively stronger for intense emotional stimuli than for neutral stimuli. These findings are discussed in relation to multivariate methods and emotion theories.     

Neurocognition in schizophrenia: a study of the productivity and visibility of Spanish authors

This paper provides a map of the scientific productivity of authors affiliated to a Spanish institution and who have addressed one of the most important current topics in schizophrenia: The study of cognitive performance. A search of the Web of Science yielded 125 articles that met the inclusion criteria. In order to provide a comprehensive overview of scientific productivity, we examine several bibliometric indicators, concerning both productivity and impact or visibility. The analysis also focuses on qualitative aspects of key theoretical importance, such as the kinds of cognitive functions that are most often assessed and the tests most widely used to evaluate them in clinical practice. The study shows that interest in the subject of cognitive function in schizophrenia has increased considerably in Spain since the beginning of this century. The results also highlight the need to standardize the type of tests to be used in the cognitive assessment of patients with schizophrenia.     

Assessing cross-partner associations in physiological responses via coupled oscillator models

A host of theoretical frameworks suggest associations of physiological signals between two individuals within a romantic relationship. However, few studies have provided empirical evidence of such associations using physiological reactivity from both partners in the dyad. In this study we use measures of respiration and heart rate from romantic partners recorded across three laboratory tasks. We examine the interrelations of each measure between both dyad members using coupled linear oscillators (Boker & Nesselroade, 2002). These models were used to capture oscillations in respiration and heart rate, and to examine interdependence in the physiological signals between both partners. Results show that associations were detectable within all three tasks, with different patterns of coupling within each task. Discussion centers on ways to investigate the synchrony of physiological responses across within relationships, including the promises of and obstacles for doing so.     

Gender Differences in the Relations among Patriarchal Beliefs,Parenting, and Teen Relationship Violence in Mexican Adolescents

Teen relationship violence is a global phenomenon associated with adverse outcomes. As in other countries, teen relationship violence is of concern in Mexico. However, few studies have examined the risk and protective factors of teen relationship violence among Mexican adolescents. This study examined whether patriarchal beliefs and exposure to authoritarian parenting among Mexican adolescents are associated with perpetration and victimization of physical and verbal-emotional teen relationship violence. Two hundred and four students (15–18 years old) from Monterrey, Mexico, completed questionnaires. Hierarchical regression analyses controlling for age revealed that among girls, authoritarian parenting was associated with physical and verbal-emotional victimization and verbal-emotional violence perpetration. Among boys, higher endorsement of patriarchal beliefs was associated with lower reports of physical perpetration and physical victimization.     

Age and Gender Differences in Teen Relationship Violence

Research shows that abuse in adolescence can start early and current literature regarding gender differences in teen relationship violence (TRV) is inconsistent. Age and gender differences in TRV were examined. Measures assessing TRV and its correlates were completed by 231 teens from 7th-, 9th-, and 11th-grade classes. A 2 (gender) by 3 (grade) multivariate analysis of variance revealed significant effects for grade and gender indicating that 7th graders have lower perpetration and victimization of TRV, less anger control, and fewer positive conflict resolution behaviors than 9th and 11th graders. Furthermore, girls perpetrate more physical and emotional abuse, whereas boys perpetrate more sexual abuse. Results have implications for timing and content of prevention programs addressing dating violence in adolescence.     

Cultural differences in the development of processing speed

The aim of the present work was to examine cultural differences in the development of speed of information processing. Four samples of US children (N = 509) and four samples of East Asian children (N = 661) completed psychometric measures of processing speed on two occasions. Analyses of the longitudinal data indicated that, although processing speed was comparable among US and East Asian children at the youngest age (~4.5 years), it developed more rapidly in some but not all of the East Asian samples. Results are discussed in terms of factors that may promote more rapid development of processing speed in some East Asian cultures.
