Exploring Conflict Resolution and Psychological Abuse Across Romantic Relationships

Although strengthening skills is recommended to improve the effectiveness of programs to prevent dating violence, little research has analyzed how conflict resolution strategies relate to victimization/perpetration trajectories. This study explores retrospectively self-reported conflict resolution strategies (positive problem-solving, engagement, and withdrawal) across 2 romantic relationships, paying special attention to possible changes. Participants were 309 college students who had been involved in 1, 2, or no abusive relationships. Based on these experiences, they were first classified into 4 groups according to their psychological victimization (non-victimized, pre-victimized, newly-victimized, and re-victimized) in each of their 2 relationships. Subsequently, they were also classified into 4 different groups according to their perpetration (non-perpetrators, pre-perpetrators, new perpetrators, and re-perpetrators). Changes in conflict resolution strategies were self-reported by both the victims and the perpetrators with a single abusive relationship, whereas persistence was detected in those involved in either 2 abusive relationships (re-victimized and re-perpetrators) or none at all. The results can help prevent dating violence across relationships and its negative consequences for health.     

Attention and spatial resolution: a theoretical and experimental study of visual search in hierarchical patterns

Our aim has been to study visual search in hierarchical patterns through a computational neuroscience perspective. In this way we were able to analyse the relationship between the global precedence effect and attention. The theoretical part of our investigations extended a model built upon the biased-competition hypothesis. An important feature of this extension is that different spatial frequencies are processed with different time constants. Simulations with this model resulted in specific predictions that were confirmed with a novel visual-search experiment utilising hierarchical patterns. Both experiment and simulations suggest that the global-precedence effect prevails under the condition of visual search.     

Spanish developmental dyslexia: Prevalence, cognitive profile, and home literacy experiences

This study was designed to examine the prevalence, cognitive profile, and home literacy experiences in subtypes of Spanish developmental dyslexia. The subtyping procedure used comparison with chronological-age-matched and reading-level controls on reaction times and accuracy responses to high-frequency words and pseudowords. Using regression-based procedures, 8 phonological dyslexics and 16 surface dyslexics were identified from a sample of 35 dyslexic fourth graders by comparing them with chronological-age-matched controls on reaction times to high-frequency word and pseudoword reading. However, when the dyslexic subtypes were defined by reference to reading-level controls, 12 phonological dyslexics were defined but only 5 surface dyslexics were identified. Both dyslexic subtypes showed a deficit in phonological awareness, but children with surface dyslexia also showed a deficit in orthographical processing assessed by a homophone comprehension task. This deficit was associated with poor home literacy experiences, with the group of parents with children matched in reading age, in comparison with the group of parents with children with surface dyslexia, reporting more literacy home experiences.     

Early detection of drug use and bullying in secondary school children by using a three-dimensional simulation program

The current study analyzes the psychometric properties of an innovative three-dimensional (3D) simulation program, entitled Mii-School (MS), designed for the early detection of drug use and bullying in Secondary School children. This computer program showed adequate reliability and construct validity. The factorial structure, as well as the explanatory weight of the different factors, is presented. In addition, the results of a parallel version in paper and pencil format are also presented and compared with those of the computerized version (i.e., MS). There was a statistically significant difference between the two formats in the total (i.e., combined) sore of risk. When drug use and bullying were separately analyzed, differences were found only with regard to drug use. The relevance of these results as well as the suitability of this type of 3D instrument for the early detection of risky behaviors in young people are discussed.     

Psychometric Properties of the Child Posttraumatic Cognitions Inventory in a Sample of Brazilian Children

Cognitive models of trauma propose that maladaptive cognitions in children and adolescents are causally implicated in the unfolding and maintenance of posttraumatic response. The objective of this study was to evaluate the psychometric properties of the Child Posttraumatic Cognitions Inventory (CPTCI). The sample included 131 children and adolescents. The psychometric properties of the CPTCI were examined, including reliability and convergent validity. The results showed high internal consistency for both CPTCI total scale (α = .90) and its subscales (CPTCI–PC α = .88 and CPTCI–SW α = .79) and a 2-component solution explaining 37.63% of the variance of CPTCI. Convergent validity evidence was obtained through correlations with the Trauma Symptom Checklist for Children and Children’s Depression Inventory. Findings suggest that CPTCI instruments are reliable and had adequate evidence of validity.     

Mouse vocal communication system: Are ultrasounds learned or innate?

Mouse ultrasonic vocalizations (USVs) are often used as behavioral readouts of internal states, to measure effects of social and pharmacological manipulations, and for behavioral phenotyping of mouse models for neuropsychiatric and neurodegenerative disorders. However, little is known about the neurobiological mechanisms of rodent USV production. Here we discuss the available data to assess whether male mouse song behavior and the supporting brain circuits resemble those of known vocal non-learning or vocal learning species. Recent neurobiology studies have demonstrated that the mouse USV brain system includes motor cortex and striatal regions, and that the vocal motor cortex sends a direct sparse projection to the brainstem vocal motor nucleus ambiguous, a projection previously thought be unique to humans among mammals. Recent behavioral studies have reported opposing conclusions on mouse vocal plasticity, including vocal ontogeny changes in USVs over early development that might not be explained by innate maturation processes, evidence for and against a role for auditory feedback in developing and maintaining normal mouse USVs, and evidence for and against limited vocal imitation of song pitch. To reconcile these findings, we suggest that the trait of vocal learning may not be dichotomous but encompass a broad spectrum of behavioral and neural traits we call the continuum hypothesis, and that mice possess some of the traits associated with a capacity for limited vocal learning.     

Conflict,consensus, and liberty in J. S. Mill’s representative democracy

The relationship between representative democracy and conflict in John Stuart Mill’s political philosophy has been interpreted in very different ways. While some scholars claim that Millian democracy is incompatible with political conflict, others identify in Mill a radical political agonism that would offer a non-consensual model of deliberative democracy. This paper argues that neither of these views is exactly accurate: although he highlights the centrality of conflict in political life, Mill believes that democratic deliberation presupposes a minimal level of consensus regarding the formal value of democracy’s basic principles, viz. the principles of individual freedom and equality. Initially, I shall reconstruct the relationship between conflict and consensus in Mill’s conception of representative democracy. I shall then investigate his association of representation and advocacy and show that Mill’s encomium on political conflict was influenced by Guizot’s work. Finally, I shall explain how a democratic debate riven with conflict is conducive to individual freedom.
