Life events as predictors of mania and depression in bipolar I disorder

To date, few prospective studies of life events and bipolar disorder are available, and even fewer have separately examined the role of life events in depression and mania. The goal of this study was to prospectively examine the role of negative and goal-attainment life events as predictors of the course of bipolar disorder. One hundred twenty-five individuals with bipolar I disorder were interviewed monthly for an average of 27 months. Negative and goal-attainment life events were assessed with the Life Events and Difficulties Schedule. Changes in symptoms were evaluated using the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Scale. The clearest results were obtained for goal-attainment life events, which predicted increases in manic symptoms over time. Negative life events predicted increases in depressive symptoms within regression models but were not predictive within multilevel modeling of changes in depressive symptoms. Given different patterns for goal attainment and negative life events, it appears important to consider specific forms of life events in models of bipolar disorder.     

Maladaptive personality traits and psychopathology in childhood and adolescence: the moderating effect of parenting

This study examines child and adolescent psychopathology from a maladaptive trait perspective, incorporating both parental and child ratings of parenting as a moderator of the personality-psychopathology association. Hierarchical moderated regression analyses were conducted on a combined sample of referred and nonreferred children and adolescents (N=862, parental ratings of parenting and N=396, child ratings of parenting). The results indicated positive main effects of maladaptive traits on externalizing and internalizing problems, and positive main effects of parental negative control on externalizing problems. Significant interactions were found for Disagreeableness and Emotional Instability with parental Negative Control and for Disagreeableness x Positive Parenting in explaining externalizing problems. The discussion focuses on the contribution of these findings to a better understanding of the trait-psychopathology relationship at young age.     

Eyewitness memory following discussion: using the MORI technique with a Western sample

Researchers studying memory conformity have made significant advances in our understanding of the phenomenon, but have used methods with significant shortcomings. Mori's three‐stage method addresses many of these concerns. To date the technique has not been replicated on a Western sample. We present such a study, and discuss two significant improvements to Mori's method. We found that subjects were more likely to report the correct answer for non‐discussed critical details than discussed critical details. Our data also suggested that when subjects agreed with their partner's information during the discussion, they did so because they thought that information was accurate; only a minority of the time did they go along with their partner during discussion and revert to their own answer at the test. We draw parallels between the unknown mechanisms driving memory conformity effects and the search for mechanisms driving the misinformation effect two decades ago.

Photographs can distort memory for the news

In this experiment, we ask whether photographs can lead to false memories for elements of a newspaper story. Participants played the role of a newspaper editor, identifying minor typographical errors in three newspaper articles and marking the text where they thought an accompanying photo should be placed when the story was printed. The critical article described a hurricane's effects on a coastal region; the story made no mention of personal injury or death. We varied the accompanying critical photo: participants saw either a photo of a village before the hurricane hit or after. In a later memory test, both ‘Before’ and ‘After’ participants were equally good at correctly recognising old statements and rejecting weak lures. However, the ‘After’ participants claimed to have read information describing death and injury 32% of the time. By comparison, ‘Before’ participants claimed to have read these statements only 9% of the time. Copyright © 2007 John Wiley & Sons, Ltd.     

Normative Reasons and the Agent-Neutral/Relative Dichotomy

The distinction between the agent-relative and the agent-neutral plays a prominent role in recent attempts to taxonomize normative theories. Its importance extends to most areas in practical philosophy, though. Despite its popularity, the distinction remains difficult to get a good grip on. In part this has to do with the fact that there is no consensus concerning the sort of objects to which we should apply the distinction. Thomas Nagel distinguishes between agent-neutral and agent-relative values, reasons, and principles; Derek Parfit focuses on normative theories (and the aims they provide to agents), David McNaughton and Piers Rawling focus on rules and reasons, Skorupski on predicates, and there are other suggestions too. Some writers suspect that we fundamentally talk about one and the same distinction. This work is about practical reasons for action rather than theoretical reasons for belief. Moreover, focus is on whether reasons do or do not essentially refer to particular agents. A challenge that undermines the dichotomy in this sense is posed. After having rejected different attempts to defend the distinction, it is argued that there is a possible defence that sets out from Jonathan Dancy’s recent distinction between enablers and favourers.     

How Are Traits Related to Problem Behavior in Preschoolers? Similarities and Contrasts Between Temperament and Personality

The lack of empirical research relating temperament models and personality hinders conceptual integration and holds back research linking childhood traits to problem behavior or maladjustment. This study evaluates, within a sample of 443 preschoolers, the relationships between children’s maladaptation and traits measured by three temperament models (Thomas and Chess, Buss and Plomin, and Rothbart), and a Five-Factor based personality model. Adequate reliabilities and expected factor structures are demonstrated for most scales. A joint principal component analysis combining 28 temperament and 18 personality scales indicates a six-factor model, distinguishing Sociability, Activity, Conscientiousness, Disagreeableness, Emotionality, and Sensitivity. Regression analyses reveal that although single temperament and personality scales explain from 23% to 37% of problem behavior variance, the six components explain from 41% to 49% and provide a clearer differentiation among CBCL-problem scales. This age-specific taxonomy refines and corroborates conclusions based on narrative reviews and furnishes a more balanced view of trait–maladjustment relationships.

Why individuals protest the perceived transgressions of their country: the role of anger, shame, and guilt

The present research examined emotions as predictors of opposition to policies and actions of one's country that are perceived to be illegitimate. Two studies investigated the political implications of American (Study 1) and British (Study 2) citizens' anger, guilt, and shame responses to perceived harm caused by their countries' occupation of Iraq. In both studies, a manipulation of pervasive threat to the country's image increased participants' shame but not guilt. The emotions predicted political action intentions to advocate distinct opposition strategies. Shame predicted action intentions to advocate withdrawal from Iraq. Anger predicted action intentions to advocate compensation to Iraq, confrontation of agents responsible, and withdrawal from Iraq. Anger directed at different targets (ingroup, ingroup representative, and outgroup representative) predicted action intentions to support distinct strategies (Study 2). Guilt did not independently predict any political action intentions. Implications for the study of political action and emotions in intergroup contexts are discussed.
