Rational social and political polarization

Philosophical Studies - Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief...     

Locke's Theory of Demonstration and Demonstrative Morality

Locke famously claimed that morality was capable of demonstration. But he also refused to provide a system of demonstrative morality. This paper addresses the mismatch between Locke's stated views and his actual philosophical practice. While Locke's claims about demonstrative morality have received a lot of attention it is rare to see them discussed in the context of his general theory of demonstration and his specific discussions of particular demonstrations. This paper explores Locke's general remarks about demonstration as well as his claims about demonstration in natural philosophy, mathematics, and morality. Careful attention to these detailed discussions motivates a reevaluation of Locke's views on demonstrative knowledge of morality. Specifically, while Locke did believe that some demonstrative moral knowledge might be in‐principle available to us he also believed that facts about the difficulty of demonstration meant that this knowledge would in‐practice be largely unattainable.     

Youth Needs at Intake into Trauma‐Informed Group Homes and Response to Services: An Examination of Trauma Exposure,Symptoms, and Clinical Impression

Trauma‐informed care is recommended to improve the quality of group home services for youth. Youth exposure to trauma and associated symptoms are important factors involved in making the clinical impression that determines treatment services. This study considered three dimensions of trauma (exposure, symptoms, and clinical impression) to determine associations with behavioral incidents of youth in trauma‐informed group homes and how trauma was related to changes in psychopathology from intake to discharge. Archival records of youth (N = 1,096), age 9–18 (M = 15.7 years) who received services from January 2013 to December 2017, and departed the program were used. Statistical procedures included hierarchical linear modeling and analysis of covariance. Results indicated trauma symptoms predicted emotional problems and self‐injurious behavior. Youth in high‐ and low‐trauma groups both showed decreases in behavioral incidents and psychopathology, but clinical impression of trauma moderated the change in emotional problems from intake to discharge. Youth deemed by clinicians to have lower trauma (based on history of maltreatment and expression of trauma symptoms) had greater decrease in emotional problems from admission to discharge. Limitations and implications for further research on implementation and effectiveness of trauma‐informed models are discussed.     

Parental styles,gender and the development of hope and self‐esteem

We examined the developmental trajectory of trait hope and self‐esteem over 4 years and the impact of gender and perceived parental styles on these trajectories. Participants were 884 high school students. There was a general decline in hope and self‐esteem over time, with females declining more rapidly than males. Girls had higher hope than boys in Grade 7, but lower hope by Grade 10. Perceived parental authoritativeness at Time 1 was related to high hope across the 4 years, whilst perceived parental authoritarianism was related to low self‐esteem. We discuss the importance of perceived parental styles for adolescent well being, as well as possible explanations for changes in hope and self‐esteem. Copyright © 2008 John Wiley & Sons, Ltd.     

Maladaptive perfectionism as an intervening variable between psychological control and adolescent depressive symptoms: a three-wave longitudinal study.

Maladaptive perfectionism has been postulated as an intervening variable between psychologically controlling parenting and adolescent internalizing problems. Although this hypothesis has been confirmed in a number of cross-sectional studies, it has not yet been examined from a longitudinal perspective. Findings from this 3-wave longitudinal study show that parental psychological control (as indexed by parent and adolescent reports) at age 15 years predicted increased levels of maladaptive perfectionism 1 year later. Maladaptive perfectionism, in turn, predicted increased levels of adolescent depressive symptoms again 1 year later and acted as a significant intervening variable between parental psychological control at Time 1 and depressive symptoms at Time 3. Multigroup analyses show that the model tested was consistent across gender for paternal psychological control but not for maternal psychological control. Suggestions for future research are outlined.     

The link between motor impairment level and motor imagery ability in children with developmental coordination disorder

The present study examined motor imagery ability in children with developmental coordination disorder (DCD). Specifically, it explored whether children with varying degrees of motor impairment differed in their ability to perform motor imagery tasks. Fourty-two children scoring below the 15th percentile on the Movement ABC were split into two groups--DCD severe (DCD-S), scoring on or below the 5th percentile, and DCD mild (DCD-M), scoring from the 6th to 15th percentiles--and compared to 21 age matched controls. Participants performed two motor imagery tasks--hand (performed without and with specific imagery instructions) and whole-body rotation. The results demonstrated that children in the DCD-S group had a generalized motor imagery deficit in that they were less accurate across tasks than controls (and the DCD-M group on the hand task) and showed little benefit when given specific imagery instructions. The DCD-M group appeared capable of performing simpler motor imagery transformations, but were less successful as task complexity increased. Unlike the DCD-S group, the DCD-M group did show some benefit from specific imagery instructions with increases in accuracy on the hand task. These results suggest that a motor imagery deficit does exist in many children with DCD but that its presentation can vary--factors such as the individual child's level of motor impairment and task complexity appear to be linked to the profile of deficits observed, which could explain the inconsistent findings of previous studies. Although this study lends support to the theory that a deficit in internal modeling is an underlying problem for children with DCD, still more research is required to develop the theory further.     

Parent–child interactions and relational aggression in peer relationships

The major aim of this review is to propose new ways of thinking about the role of parents in the development and course of children’s relationally aggressive behavior. An important theoretical framework from which to start thinking about linkages between parenting and relational aggression is provided by attachment theory. Attachment theory proposes that early family experiences are an important basis for the development of later peer relationships. Recent studies are only beginning to suggest possible linkages between children’s parental attachment and relational aggression. One possible reason for the scant research is that theoreticians studying these constructs have not yet developed a conceptual framework combining the two, but rather have focused on different characteristics of different interpersonal contexts. Based on the premise that both relational aggression and attachment are relational constructs and given the already established correlations between insecure attachment and physical aggression, this paper will attempt to devise a heuristic model that may serve as an aid to discover links between parent–child interactions, attachment, and relational aggression. Finally, implications for future studies of relational aggression are discussed.
