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.     

Correlates and consequences of uncertainty in career aspirations: Gender differences among adolescents in England

Young people today face a great deal of uncertainty regarding their career opportunities, yet relatively little information is known about the correlates and consequences of uncertain aspirations. Drawing upon the Longitudinal Study of Young People in England (LSYPE) born in 1989/90, this study examined a pathway model investigating whether uncertain career aspirations and other associated variables mediate the link between socioeconomic status and prior achievement and later educational outcomes. Gender differences were also examined. Findings indicate that adolescents who had lower prior achievement and were from lower socioeconomic backgrounds were more likely to have uncertainty in their career aspirations. The hypothesized model was supported to some extent, indicating that uncertain career aspirations and other associated variables were significant mediators. Unexpectedly, adolescents with uncertain career aspirations had higher academic performance at age 16 and a greater likelihood of educational enrollment at age 18 compared to those with high, certain aspirations, when parental educational expectations, school motivation, perceived academic ability and useful career advice were taken into account, suggesting that these young people may benefit from an extended period of moratorium in their career choice.     

Norming the odd: Creation,norming, and validation of a stimulus set for the study of incongruities across music and language

Research into similarities between music and language processing is currently experiencing a strong renewed interest. Recent methodological advances have led to neuroimaging studies presenting striking similarities between neural patterns associated with the processing of music and language—notably, in the study of participants’ responses to elements that are incongruous with their musical or linguistic context. Responding to a call for greater systematicity by leading researchers in the field of music and language psychology, this article describes the creation, selection, and validation of a set of auditory stimuli in which both congruence and resolution were manipulated in equivalent ways across harmony, rhythm, semantics, and syntax. Three conditions were created by changing the contexts preceding and following musical and linguistic incongruities originally used for effect by authors and composers: Stimuli in the incongruous–resolved condition reproduced the original incongruity and resolution into the same context; stimuli in the incongruous–unresolved condition reproduced the incongruity but continued postincongruity with a new context dictated by the incongruity; and stimuli in the congruous condition presented the same element of interest, but the entire context was adapted to match it so that it was no longer incongruous. The manipulations described in this article rendered unrecognizable the original incongruities from which the stimuli were adapted, while maintaining ecological validity. The norming procedure and validation study resulted in a significant increase in perceived oddity from congruous to incongruous–resolved and from incongruous–resolved to incongruous–unresolved in all four components of music and language, making this set of stimuli a theoretically grounded and empirically validated resource for this growing area of research.     

Comparing the Eysenck and HEXACO Models of Personality in the Prediction of Adult Delinquency

Drawing from self and peer reports of personality, the present study compares the structures of the HEXACO and Eysenck models of personality and the models' capacity to predict self reported acts of delinquency. Correlations amongst scales revealed that Psychoticism captures elements of both HEXACO Emotionality and Conscientiousness. The Eysenck Lie scale correlated positively with both self and peer reported HEXACO Honesty–Humility and Conscientiousness, suggesting that this validity scale includes substantive variance relating to the latter factors. Regression analyses of personality data from both rater sources revealed that Honesty–Humility and Psychoticism were strong predictors of delinquency that independently offered substantial incremental validity. For self reports, the Extraversion and Lie scales were also strong unique predictors of delinquency. Copyright © 2011 John Wiley & Sons, Ltd.     

Genetic and environmental influences on executive functions and intelligence in middle childhood

Executive functions (EFs) and intelligence (IQ) are phenotypically correlated. In twin studies, latent variables for EFs and IQ display moderate to high heritability estimates; however, they show variable genetic correlations in twin studies spanning childhood to middle age. We analyzed data from over 11,000 children (9- to 10-year-olds, including 749 twin pairs) in the Adolescent Brain Cognitive Development (ABCD) Study to examine the phenotypic and genetic relations between EFs and IQ in childhood. We identified two EF factors—Common EF and Updating-Specific—which were both related to IQ (rs = 0.64–0.81). Common EF and IQ were heritable (53%–67%), and their genetic correlation (rG = 0.86) was not significantly different than 1. These results suggest that EFs and IQ are phenotypically but not genetically separable in middle childhood, meaning that this phenotypic separability may be influenced by environmental factors.     

Episodic intertrial learning of younger and older participants: Effects of age of acquisition

There is clear evidence of a deficit in episodic memory for older adults compared to younger adults. Using an intertrial technique previous research has investigated whether this deficit can be attributed to a decline in encoding or consolidation. On standard memory tests, these two aspects of memory function can be measured by examining the items forgotten or acquired across multiple learning trials. The present study assessed whether age deficits in episodic memory were affected by stimulus characteristics, specifically age of acquisition (AoA). A standard intertrial design was implemented whereby participants studied word lists over several study-test trials. The stimulus characteristics of AoA were manipulated using a pure-list technique. Our findings showed that older adults demonstrate an overall recall deficit which appeared to be a consequence of both an encoding deficit and consolidation weakness. Earlier-acquired words were recalled significantly better than later-acquired words and this was apparently due to both enhanced encoding and consolidation of earlier- over later-acquired words. The key finding is that older adults show a recall advantage for earlier- compared to later-acquired words over the entire experiment to a greater degree than younger adults.     

Job design,opportunities for skill utilization,and intrinsic job satisfaction

Arguably, job designs that provide for high levels of employee control also provide increased opportunities for the development and exercise of skill. Perceived skill utilization has consistently been found to be amongst the strongest predictors of job-related affective well-being, yet is frequently neglected in studies of work redesign. In this article, a theoretical framework linking the key job characteristics of perceived control and perceived cognitive demand to perceived skill utilization and intrinsic job satisfaction is presented. Results from one cross-sectional study and one longitudinal study are reported that support the mediational influence of perceived skill utilization on the perceived job control?–?job satisfaction relationship only. The relationship between perceived job demand and perceived skill utilization was mixed but no mediating effect was evident. It is argued that the level of both perceived demand and perceived control dictates the nature of the joint influence of both job characteristics on perceived skill utilization and work attitudes such as job satisfaction.     

Episodic intertrial learning of younger and older adults: Effects of word frequency

ABSTRACT

Older adults have a demonstrable episodic memory deficit. The present study aimed to investigate whether the age deficit in episodic memory was influenced by stimulus characteristics known to produce differences in memory performance in younger adults, specifically word frequency. An intertrial paradigm was used whereby participants studied high- or low-frequency lists over several study-test trials, and the loss and gain of individual items was measured across trials; putative measures of consolidation and encoding. The results show that high-frequency words are recalled significantly better than low-frequency words. Older adults acquired high-frequency words at a greater rate across trials than they did for low-frequency words, an effect not evident in the younger adults. Older adults were found to have deficits in both encoding and consolidation as measured by losses and gains of items across trials. The results support the inter-item association theory of the word frequency effect on recall, with the age differences suggesting that memory deficits are sensitive to stimuli characteristics – one interpretation being that the ease of processing of the stimuli at encoding facilitates later recall.     

Change Over Time: Conducting Longitudinal Studies of Children's Cognitive Development

Developmental scientists have argued that the implementation of longitudinal methods is necessary for obtaining an accurate picture of the nature and sources of developmental change (Magnusson & Stattin, 2006 Magnusson , D. , & Stattin , H. ( 2006 ). The person in context: A holistic-interactionistic approach . In R. M. Lerner & W. Damon (Eds.), Handbook of child psychology: Vol. 1. Theoretical models of human development ( , 6th ed. , pp. 400 – 464 ). Hoboken , NJ : John Wiley & Sons . [Google Scholar]; Morrison & Ornstein, 1996 Morrison , F. J. , & Ornstein , P. A. ( 1996 ). Cognitive development . In R. B. Cairns , G. R. Elder & E. Costello (Eds.), Developmental science (pp. 121 – 134 ). New York , NY : Cambridge University Press . [Google Scholar]). Developmentalists studying cognition have been relatively slow to embrace longitudinal research, and thus, few exemplar studies have tracked individual children's cognitive performance over time and even fewer have examined contexts that are associated with this growth. In this article, we first outline some of the benefits of implementing longitudinal designs. Using illustrations from existing studies of children's basic cognitive development and of their school-based academic performance, we discuss when it may be appropriate to employ longitudinal (vs. other) methods. We then outline methods for integrating longitudinal data into one's research portfolio and contrast the leveraging of existing longitudinal data sets with the launching of new longitudinal studies to address specific questions concerning cognitive development. Finally, for those who are interested in conducting longitudinal investigations of their own, we provide practical on-the-ground guidelines for designing and carrying out such studies of cognitive development.
