Can Perceived Burdensomeness Explain the Relationship Between Suicide and Perfectionism?

The perception of being a burden to others has been associated with suicidal ideation and behavior. Maladaptive aspects of perfectionism have also been associated with suicidal thinking and behavior. The purpose of the current study was to investigate whether perceived burdensomeness would act as a mediator between maladaptive perfectionism and suicidal ideation. Results indicated that perceived burdensomeness mediated the relationship between maladaptive perfectionism and suicidal ideation, which suggest that the perception of burdensomeness may be one aspect of the mechanism by which perfectionism can lead to such psychological distress that it becomes a predictor of suicidal ideation. Clinical implications of this relationship are discussed.     

How Can Evolutionary Psychology Successfully Explain Personality and Individual Differences?

ABSTRACT— Although evolutionary psychology has been successful in explaining some species-typical and sex-differentiated adaptations, a large question that has largely eluded the field is this: How can the field successfully explain personality and individual differences? This article highlights some promising theoretical directions for tackling this question. These include life-history theory, costly signaling theory, environmental variability in fitness optima, frequency-dependent selection, mutation load, and flexibly contingent shifts in strategy according to environmental conditions. Tackling the explanatory question also requires progress on three fronts: (a) reframing some personality traits as forms of strategic individual differences; (b) providing a nonarbitrary, evolutionary-based formulation of environments as distributions and salience profiles of adaptive problems; and (c) identifying which strategies thrive and which falter in these differing problem-defined environments.     

Does Conscientiousness Explain the Relationship Between Integrity and Job Performance?

There is a meta-analytic evidence that scores on integrity tests are related to measures of overall job performance, but it is not clear why this relationship exists. One hypothesis that would account for this correlation is that both integrity and performance measures are related to the personality trait conscientiousness, and that statistically controlling for conscientiousness would substantially reduce the integrity-performance correlation. To test this hypothesis, we used the results of three meta-analyses to estimate the components needed to calculate the partial correlation between integrity and performance, controlling for conscientiousness. Partialling had little effect; the best estimate of the corrected zero-order and partial correlations between integrity and performance were 0.34 and 0.28, respectively. Sensitivity analyses suggest that imprecision in the estimates of the various components of this partial correlation cannot reasonably explain the small effects of partialling.     

How Do Logics Explain?

Anti-exceptionalists about logic maintain that it is continuous with the empirical sciences. Taking anti-exceptionalism for granted, we argue that traditional approaches to explanation are inadequate in the case of logic. We argue that Andrea Woody's functional analysis of explanation is a better fit with logical practice and accounts better for the explanatory role of logical theories.     

Can Outcome Expectancies Help Explain Sex Differences in Direct and Indirect Aggression?

This study examined the role of outcome expectancies in explaining sex differences in adolescents' inclination to engage in acts of aggression. Using a sample of Australian adolescents, 2 scales were developed to measure outcome expectancies of direct and indirect aggression. The data were used in subsequent mediation analyses. Sex differences in direct aggression were partially mediated by 2 types of aggression expectancies. Relative to females, males anticipated more overall benefits associated with acting aggressively and less fear of reprisals from authority figures. This pattern of expectancy beliefs predicted higher levels of self‐reported direct aggression. Sex differences in indirect aggression were fully mediated by anticipation of personal benefits, with males expecting greater personal benefits for engaging in this type of aggression.     

“Explain” in scientific discourse

The philosophical literature on scientific explanation contains a striking diversity of accounts. I use novel empirical methods to address this fragmentation and assess the importance and generality of explanation in science. My evidence base is a set of 781 articles from one year of the journal Science, and I begin by applying text mining techniques to discover patterns in the usage of “explain” and other words of philosophical interest. I then use random sampling from the data set to develop and test a classification scheme for scientific explanation. My results show that explanation and inference to the best explanation are ubiquitous in science, that they occur across a wide range of scientific disciplines, and that they are a goal of scientific practise. These explanations and inferences to the best explanation come in a diversity forms, which at least partially justifies the fragmentation of philosophical accounts. I draw two methodological lessons: first that text mining can enhance traditional conceptual analysis by establishing facts about word usage; and second that random sampling of cases can increase our confidence that a philosophical account applies in general. These empirical techniques supplement traditional philosophical methods.     

Suggestibility From Stories: Can Production Difficulties and Source Monitoring Explain a Developmental Reversal?

Children's memories improve throughout childhood, and this improvement is often accompanied by a reduction in suggestibility. In this context, it is surprising that older children learn and reproduce more factual errors from stories than do younger children (Fazio & Marsh, 2008 Fazio , L. K. , & Marsh , E. J. ( 2008 ). Older, not younger, children learn more false facts from stories . Cognition , 106 , 1081 – 1089 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The present study examined whether this developmental reversal is limited to production tests, or whether younger children are still less suggestible when the final test (multiple-choice) asks them to recognize the answer. A second goal was to explore the role of source monitoring in children's suggestibility by examining children's awareness of learning within, versus before, the experiment. Five-year-olds and 7-year-olds listened to stories containing correct, neutral, and misleading references and later took either a multiple-choice or short-answer general knowledge test. In addition, they judged whether each answer had appeared in the stories and whether they had known it before the experiment. Critically, a developmental reversal in suggestibility was observed on both tests; younger children were less suggestible even when faced with the story errors at test. Although older children showed superior source discriminability for whether their answers had appeared in the stories, they showed an illusion of prior knowledge, believing they had known their misinformation answers all along. To this effect, older children's increased suggestibility may be due not only to their superior memory capacity for specific story errors, but also to their ability and tendency to integrate story information into their knowledge base.     

Can Executive Functions Explain the Relationship Between Attention Deficit Hyperactivity Disorder and Social Adjustment?

This study examined the ability of executive functions (EF) to account for the relationship between Attention Deficit Hyperactivity Disorder (ADHD) status and social adjustment as indexed by parent and teacher report and by performance on a standardized observational “chat room” task. Children with the Combined subtype (ADHD-C; n = 23), the Primarily Inattentive Subtype (ADHD-I; n = 33), and non-ADHD controls (n = 36) participated. EF did not mediate the relationship between ADHD status and parent or teacher report of social adjustment. EF accounted for about 40–50% of the variance between ADHD status and the ability of children to detect subtle verbal cues as well as memory for the conversation in the chat room task, but did not mediate the relationship between ADHD and the number of prosocial, hostile, or on-topic statements that were made. Results are consistent with other recent reports, and suggest that the role of EF deficits in the production of social skill deficits in ADHD may not be as prominent as is typically assumed. The implications for the development of intervention programs designed to target core cognitive etiologic factors are discussed.     

Unpacking Social Avoidance and Substance Use in Social Anxiety: Does Extraversion Explain Behavior Variability?

Social anxiety is characterized by heightened fear and anxiety associated with social situations, resulting in the use of avoidance behaviors. Contemporary models suggest that some individuals with social anxiety may choose to completely avoid social situations, while others may seek social connections and interactions and utilize avoidance behaviors such as substance use as a means of distress tolerance, while engaging in these situations. Our aim is to test a theoretical model whereby extraversion could help to explain the heterogenous nature of social anxiety in relation to these behaviors. Lower levels of extraversion have been commonly associated with withdrawal behaviors and higher levels of extraversion have been associated with behaviors commonly enacted in social situations. Understanding factors which predict the use of one behavior over another is imperative to the conceptualization and successful treatment of patients with social anxiety. A sample of 195 college students completed self-report measures and a 10-day experience sampling diary with five diary signals each day. Participants were asked to rate their current negative emotions and behaviors during each diary signal. Using a multilevel modeling approach, we tested the association between social anxiety symptoms and negative affect predicting engagement in substance use or social avoidance and tested whether extraversion moderated this association. Negative affect was included as a covariate given the established associations between elevations in negative affect predicting both behaviors. Results indicated that higher levels of social anxiety symptoms and negative affectivity increased the probability of social avoidance and substance use, and extraversion was a significant predictor for only substance use. Moderation analysis indicated that extraversion moderated the relationship between social anxiety and substance use, suggesting a stronger positive relationship between substance use and social anxiety for individuals higher in extraversion. However, extraversion was not a significant moderator between social anxiety and social avoidance. Overall, the findings suggest that extraversion could be a key factor predicting the use of substances amongst individuals with social anxiety and may need further consideration in treatment.

     

Stay Loyal or Exit the Party? How Openness to Experience and Extroversion Explain Vote Switching

Following Hirschman, voters who are discontent with the party they voted for have two options: exit the party and vote for another or stay loyal. The inclination to exit or stay loyal is rooted in the Five Factor Model (FFM) of personality. We test our argument in two panel studies in Denmark and the United Kingdom. We find that citizens open to experience are more likely to switch parties since they are more likely to think about alternatives and take risks. Extroverts identify and commit themselves to organizations and stay loyal in Denmark, but we do not confirm this pattern in the United Kingdom. Our findings demonstrate that electoral volatility is, at least partly, rooted in personality.     

Biodata Validity Decay and Score Inflation with Faking: Do Item Attributes Explain Variance Across Items?

Rating scales were developed to assess the biodata dimensions offered by Mael (1991). Biodata items assessing conscientiousness were administered under honest-responding and faking-good conditions. Item attributes were examined to determine their value in predicting item validity for honest respondents and item validity for faking respondents. Analyses were also conducted to determine whether the degree of item faking was related to item attributes. Item attributes associated with item validity for honest respondents are not the same as the item attributes indicative of item validity for the faking respondents. We suggest that this makes it very difficult to develop a biodata questionnaire which will be equally valid for both honest and faking respondents.     

How Digital Computer Simulations Explain Real‐World Processes

Scientists of many disciplines use theoretical models to explain and predict the dynamics of the world. They often have to rely on digital computer simulations to draw predictions fromthe model. But to deliver phenomenologically adequate results, simulations deviate from the assumptions of the theoretical model. Therefore the role of simulations in scientific explanation demands itself an explanation. This paper analyzes the relation between real‐world system, theoretical model, and simulation. It is argued that simulations do not explain processes in the real world directly. The way in which simulations help explaining real‐world processes is conceived as indirect, mediated by the theoretical model. Simulacra are characterized further, and turn out to be a priori measurable. This gives a clue to a better understanding of the epistemic role of computer simulations in scientific research.     

Do Genetic Factors Explain the Links Between Callous-Unemotional,Attention Hyperactivity and Oppositional Defiant Problems in Toddlers?

Research demonstrates that callous-unemotional (CU) behaviors, Attention Deficit Hyperactivity Disorder (ADHD) and Oppositional Defiant Problems (ODD) are related, but little is known about the sources of covariation among the three externalizing behaviors. The present study looked at genetic and environmental links between all three behavioral domains in twins at ages 2 and 3 years (MZ = 145, DZ = 169), a time when CU behaviors are beginning to emerge. CU, ADHD, and ODD behaviors as assessed using the Child Behavior Checklist 1.5–5 (Achenbach and Rescorla 2000) were strongly interrelated at both ages. Genetic factors primarily explained the covariation among the three behavioral domains via a common externalizing factor; however, there were also genetic factors unique to each behavior. Furthermore, the majority of nonshared environmental influences on each externalizing behavior were behavior-specific. The heritable externalizing factor was highly stable across age, largely due to genetic factors shared across ages 2 and 3 years. Despite their extensive phenotypic and genetic overlap, CU, ADHD, and ODD behaviors have unique genetic and nonshared environmental influences as early as toddlerhood. This supports phenotypic research showing that the three are related but distinct constructs in very young children.     

Can a Neural System Geared to Bring About Rapid,Predictive, and Efficient Function Explain Creativity?

Abstract

Vandervert, Schimpf, and Liu (this issue) have presented a cerebellar model of creativity in the featured article by relating their ideas to processes of working memory in relation to the cerebellum as well as by generalizing the motor control role of the cerebellum to extend to non-motor facets of cognition. In the present article, I discuss the weaknesses of their approach at different levels, ranging from the inadequate definition of the construct under study and the lack of specificity in their claims, to the counterintuitive underlying rationale of their approach, and the inadequate evidence provided to cement their ideas. I end by briefly outlining what would be necessary to propound an account of creativity that is uniquely attributable to cerebellum function.     

Do Narrative Engagement and Recipients’ Thoughts Explain the Impact of an Entertainment-Education Narrative on Discouraging Binge Drinking?

Previous research suggests that narrative engagement (NE) in entertainment-education (E-E) narratives reduces counterarguing, thereby leading to E-E impact on behavior. It is, however, unclear how different NE processes (narrative understanding, attentional focus, emotional engagement, narrative presence) relate to different thought types (negative or positive; about the narrative form or about the target behavior) and to E-E impact. This study explores these relations in the context of alcohol binge drinking (BD). Participants (N = 172) watched an E-E narrative showing negative BD consequences, thereby aiming to discourage BD. The main findings were that the E-E narrative had a positive impact on discouraging BD on almost all assessed BD determinants such as beliefs and attitude. It was shown that attentional focus, emotional engagement, and narrative presence were associated with BD-discouraging impact, albeit on different BD-related determinants. No evidence was found that negative thoughts about BD mediated these associations. From this, we conclude that attentional focus, emotional engagement, and narrative presence were important for E-E impact but that negative thoughts about BD did not play a role therein. The study’s empirical and practical implications are discussed.     

Social Deviance Theories: Can They Explain Rural Vandalism in the Twenty-First Century?

Rural crime is a heavily misunderstood and marginalized area of criminology. In the United Kingdom in particular, there is limited scholarship on the issue and even less on particular types of rural crime, such as rural vandalism. With this in mind, this article reviews the applicability of five deviance theories to several forms of rural vandalism, through a less traditional lens that challenges criminological and rural norms. The article concludes by arguing that most of the theories examined are relevant to explanations of rural vandalism. However, it also emphasizes the need for a solid definition of rural crime, and an overall move away from the urban focus of criminology.     

Do Historical Changes in Parent–Child Relationships Explain Increases in Youth Conduct Problems?

The coincidence of historical trends in youth antisocial behavior and change in family demographics has led to speculation of a causal link, possibly mediated by declining quality of parenting and parent–child relationships. No study to date has directly assessed whether and how parenting and parent–child relationships have changed. Two national samples of English adolescents aged 16–17 years in 1986 (N = 4,524 adolescents, 7,120 parents) and 2006 (N = 716 adolescents, 734 parents) were compared using identical questionnaire assessments. Youth-reported parental monitoring, expectations, and parent–child quality time increased between 1986 and 2006. Ratings of parental interest did not change. Parenting differences between affluent and disadvantaged families narrowed over time. There was thus little evidence of a decline in quality of parenting for the population as a whole or for disadvantaged subgroups. Parent-reported youth conduct problems showed a modest increase between 1986 and 2006. Findings suggested that the increase in youth conduct problems was largely unrelated to observed change in parent–child relationships.
