A Systematic Review of the Relationship Between Rumination and Suicidality

Rumination has been persistently implicated in the etiology of hopelessness and depression, which are proximal predictors of suicidality. As a result, researchers have started to examine the role of rumination in suicidality. This systematic review provides a concise synopsis of the current progress in examining the relationship between rumination and suicidality, and highlights areas for future research. A search of the international literature was conducted using the three main psychological and medical databases. Eleven studies were identified providing evidence, with one exception, of a relationship between rumination and suicidality. This review also highlights the considerable dearth of studies on this area of concern, specifically of case‐control and prospective, clinical studies, in the worldwide literature.     

Statistical patterns in children’s early writing

Many theories of spelling development claim that before children begin to spell phonologically, their spellings are random strings of letters. We evaluated this idea by testing young children (mean age = 4 years 9 months) in Brazil and the United States and selecting a group of prephonological spellers. The spellings of this prephonological group showed a number of patterns that reflected things such as the frequencies of letters and bigrams in children’s language. The prephonological spellers in the two countries produced spellings that differed in some respects, consistent with their exposure to different written languages. We found no evidence for reportedly universal patterns in early spelling such as the idea that children write one letter for each syllable. Overall, our results reveal that early spellings that are not phonological are by no means random or universal and preserve certain patterns in the writing to which children have been exposed.     

Eye movements when reading transposed text: the importance of word-beginning letters

Participants' eye movements were recorded as they read sentences with words containing transposed adjacent letters. Transpositions were either external (e.g., problme, rpoblem) or internal (e.g., porblem, probelm) and at either the beginning (e.g., rpoblem, porblem) or end (e.g., problme, probelm) of words. The results showed disruption for words with transposed letters compared to the normal baseline condition, and the greatest disruption was observed for word-initial transpositions. In Experiment 1, transpositions within low frequency words led to longer reading times than when letters were transposed within high frequency words. Experiment 2 demonstrated that the position of word-initial letters is most critical even when parafoveal preview of words to the right of fixation is unavailable. The findings have important implications for the roles of different letter positions in word recognition and the effects of parafoveal preview on word recognition processes.     

The effects of focus of attention on attributional bias in patients experiencing auditory hallucinations

Cognitive models suggest that auditory hallucinations occur as the result of internal events attributed to an external source. The present study represents an attempt to evaluate the source monitoring performance of people who experience auditory hallucinations, specifically in terms of the suggested links between source monitoring, emotionality of stimuli and self-focused attention. The source monitoring performance of a group of 30 patients with a diagnosis of a schizophrenia spectrum disorder who experience auditory hallucinations was compared following successful experimental manipulation of their attention, designed to increase and decrease their levels of self-focused attention. The inclusion of words previously rated as emotionally salient by schizophrenic patients assessed the effect of emotionality on source monitoring performance. This study demonstrated that participants' ratings of both internality and control of their responses to the word association task were lower in the external focus condition than the internal focus condition. Furthermore, it was found that ratings of internality and control were lower for responses to both positive and negative stimuli compared to responses to neutral stimuli, and the magnitude of these differences was amplified in the internal focus condition relative to the external focus condition. Focus of attention has a significant effect on source monitoring performance in people experiencing auditory hallucinations. The theoretical and clinical implications of these findings are discussed.     

The Biology of Morality

Abstract. The morality of human beings, defined here as our ability to determine whether our actions are right or wrong, depends not just on following rules but also on understanding the impact of our actions on another person. How we understand the impact of our actions on another person depends on our state of consciousness, which is mediated by our brain and nervous system. We describe how we understand our morality to flow naturally from the biological state we are living in and how we see our biology and our morality as mutually interactive. A change in one changes the other. Another way of saying this is that changing either our morality or our biology changes both—changes who we are and what we do.     

Co-rumination mediates contagion of internalizing symptoms within youths' friendships

Peer contagion of internalizing symptoms was examined within youths' friendships over 6 months. Children (Grades 3 and 5) and adolescents (Grades 7 and 9) paired in 274 reciprocal same-sex friendship dyads completed measures of depressive and anxiety symptoms, co-rumination, and self-disclosure. Depression contagion was present for all youth, and anxiety contagion was found in the sample of girls and older boys. Although normative self-disclosure did not mediate the contagion effects, co-rumination mediated the depression contagion effect for adolescents and the anxiety contagion effect in the sample of girls and older boys. Implications for interventions with youth at risk for developing internalizing symptoms are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Uneasy lies the head that wears the crown: the link between guilt proneness and leadership

We propose that guilt proneness is a critical characteristic of leaders and find support for this hypothesis across 3 studies. Participants in the first study rated a set of guilt-prone behaviors as more indicative of leadership potential than a set of less guilt-prone behaviors. In a follow-up study, guilt-prone participants in a leaderless group task engaged in more leadership behaviors than did less guilt-prone participants. In a third, and final, study, we move to the field and analyze 360° feedback from a group of young managers working in a range of industries. The results indicate that highly guilt-prone individuals were rated as more capable leaders than less guilt-prone individuals and that a sense of responsibility for others underlies the positive relationship between guilt proneness and leadership evaluations.     

Treating the Capability for Suicide: A Vital and Understudied Frontier in Suicide Prevention

Current efforts at suicide prevention center largely on reducing suicidal desire among individuals hospitalized for suicidality or being treated for related psychopathology. Such efforts have yielded evidence‐based treatments, and yet the national suicide rate has continued to climb. We propose that this disconnect is heavily influenced by an unmet need to consider population‐level interventions aimed at reducing the capability for suicide. Drawing on lessons learned from other public health phenomena that have seen drastic declines in frequency in recent decades (HIV, lung cancer, motor vehicle accidents), we propose that current suicidality treatment efforts trail current suicidality theories in their lack of focus on the extent to which individuals thinking about suicide are capable of transitioning from ideation to attempt. We summarize extant evidence for specific capability‐centered approaches (e.g., means safety) and propose other options for improving our ability to address this largely overlooked variable. We also note that population‐level approaches in this regard would represent an important opportunity to decrease risk in individuals who either lack access to evidence‐based care or underreport suicidal ideation, as a reduced capability for suicide would theoretically diminish the potency of suicidal desire and, in this sense, lower the odds of a transition from ideation to attempt.
