The effect of implicit person theory on performance appraisals

Four studies examined whether implicit person theory (IPT) regarding the malleability of personal attributes (e.g., personality and ability) affects managers' acknowledgment of change in employee behavior. The extent to which managers held an incremental IPT was positively related to their recognition of both good (Study 1) and poor (Study 2) performance, relative to the employee behavior they initially observed. Incremental theorists' judgments were not anchored by their prior impressions (Study 3). In the 4th study, entity theorists who were randomly assigned to a self-persuasion training condition developed a significantly more incremental IPT. This change in IPT was maintained over a 6-week period and led to greater acknowledgment of an improvement in employee performance than was exhibited by entity theorists in the placebo control group.     

Suicidality and bereavement: complicated grief as psychiatric disorder presenting greatest risk for suicidality

The influence of complicated grief (CG) on suicidality among bereaved adults was examined. The Yale Evaluation of Suicidality scale and the Inventory of Complicated Grief-Revised were administered to 309 bereaved adults in face-to-face interviews conducted at baseline (6.2 months post-loss) and at follow-up (10.8 months post-loss). Cross-sectionally, CG was associated with a 6.58 (95% CI: 1.74-18.0) times greater likelihood of "high suicidality" at baseline, and an 11.30 (95% CI: 3.33-38.10) times greater risk of high suicidality at follow-up, after controlling for gender, race, major depressive disorder (MDD), posttraumatic stress disorder (PTSD), and social support. Longitudinally, CG at baseline was associated with an 8.21 (95% CI: 2.49-27.0) times greater likelihood of high suicidality at follow-up, controlling for the above confounders. The study results indicate that CG substantially heightened the risk of suicidality after controlling for important confounders such as MDD and PTSD, suggesting that CG poses an independent psychiatric risk for suicidal thoughts and actions.     

Overt and relational aggression and perceived popularity: developmental differences in concurrent and prospective relations

Relations of overt and relational aggression with perceived popularity among children and early adolescents were examined in 2 studies (Ns = 607 and 1,049). Among older youths, positive concurrent relations found between overt aggression and perceived popularity became nonsignificant when relational aggression was controlled, whereas positive associations found between relational aggression and perceived popularity held when overt aggression was controlled. Aggression and perceived popularity were not positively related for the younger participants. The 2nd study also examined the temporal ordering of these relations over 6 months. For older girls, positive relations between relational aggression and perceived popularity were bidirectional. For older boys, relational aggression did not predict increased perceived popularity, but perceived popularity predicted increased relational aggression. Implications for intervention are discussed.     

The Effect of Religious‐Based Mentoring on Educational Attainment: More than Just a Spiritual High?

Although research has found a positive relationship between various forms of adolescent religious involvement and educational outcomes, little research has examined connections to educational attainment. Using a nationally representative sample of youth (the National Longitudinal Study of Adolescent Health—Add Health), we examine the extent to which adolescent religiosity facilitates educational attainment (i.e., high school completion and college enrollment) and whether informal mentorships formed during adolescence with religious and nonreligious adults can help explain the link between adolescent religious involvement and educational attainment. The findings confirm that, like academic outcomes, religious youth are more likely to complete high school and enroll in college even when controlling for other individual and interpersonal factors that affect educational attainment. Furthermore, informal mentorships, particularly those with adults who have official religious positions (e.g., priest, minister, rabbi) play an important role in college enrollment.     

Lost sleep and cyberloafing: Evidence from the laboratory and a daylight saving time quasi-experiment

The Internet is a powerful tool that has changed the way people work. However, the ubiquity of the Internet has led to a new workplace threat to productivity-cyberloafing. Building on the ego depletion model of self-regulation, we examine how lost and low-quality sleep influence employee cyberloafing behaviors and how individual differences in conscientiousness moderate these effects. We also demonstrate that the shift to Daylight Saving Time (DST) results in a dramatic increase in cyberloafing behavior at the national level. We first tested the DST-cyberloafing relation through a national quasi-experiment, then directly tested the relation between sleep and cyberloafing in a closely controlled laboratory setting. We discuss the implications of our findings for theory, practice, and future research. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Emerging effortful control in toddlerhood: the role of infant orienting/regulation, maternal effortful control, and maternal time spent in caregiving activities

Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed.     

Possible number systems

Number systems—such as the natural numbers, integers, rationals, reals, or complex numbers—play a foundational role in mathematics, but these systems can present difficulties for students. In the studies reported here, we probed the boundaries of people’s concept of a number system by asking them whether “number lines” of varying shapes qualify as possible number systems. In Experiment 1, participants rated each of a set of number lines as a possible number system, where the number lines differed in their structures (a single straight line, a step-shaped line, a double line, or two branching structures) and in their boundedness (unbounded, bounded below, bounded above, bounded above and below, or circular). Participants also rated each of a group of mathematical properties (e.g., associativity) for its importance to number systems. Relational properties, such as associativity, predicted whether participants believed that particular forms were number systems, as did the forms’ ability to support arithmetic operations, such as addition. In Experiment 2, we asked participants to produce properties that were important for number systems. Relational, operation, and use-based properties from this set again predicted ratings of whether the number lines were possible number systems. In Experiment 3, we found similar results when the number lines indicated the positions of the individual numbers. The results suggest that people believe that number systems should be well-behaved with respect to basic arithmetic operations, and that they reject systems for which these operations produce ambiguous answers. People care much less about whether the systems have particular numbers (e.g., 0) or sets of numbers (e.g., the positives).     

A Multimodal Study of Childhood Trauma and Distress Tolerance in Young Adulthood

Individuals with a history of childhood trauma experience deficits in emotion regulation. However, few studies have investigated childhood trauma and both perceived (i.e., self-report) and behavioral measures of distress tolerance. The current study evaluated associations between childhood trauma (i.e., physical abuse, sexual abuse, and witnessing family violence) and measures of perceived (Distress Tolerance Scale) and behavioral distress tolerance (i.e., Paced Auditory Serial Addition Test, breath-holding). Participants were 320 undergraduate students with a history of interpersonal trauma (e.g., sexual/physical assault). Structural equation modeling was used to evaluate associations between frequency of childhood trauma type and distress tolerance. Greater childhood physical abuse was associated with higher perceived distress tolerance. Greater levels of witnessing family violence were associated with lower behavioral distress tolerance on the breath-holding task. No significant effects were found for Paced Auditory Serial Addition Test performance. Associations between childhood trauma and emotion regulation likely are complex and warrant further study.     

Single Parenthood and Adolescent Sexual Outcomes

Research suggests that children of single parents are at heightened risk of precocious sexual behavior, STDs, and other risky sexual outcomes. However, few such studies have addressed the type of single-parent family (single mother or single father), or differences across other-sex parent–child dyads. While gender essentialist models assume differences among youth living only with mothers or with fathers, constructivist models propose more flexible modes of parenting that lead to more similar outcomes. Using data from the National Longitudinal Study of Adolescent to Adult Health (n?=?2570) on youth between the ages of 15 and 19, we compared sexually-related outcomes among adolescents, both boys and girls, who lived with a single mother or a single father. These outcomes include sexual intercourse and knowledge, use of contraception, attitudes toward intimacy and pregnancy, and diagnosis of sexually-transmitted diseases. The results from linear and logistic regression models indicated few differences between single-mother and single-father families, or between same-sex and opposite-sex parent–child matches, using p values of .05 or smaller. Our results called into question essentialist models that posit higher risks for adolescents living with a particular parent or with an opposite-sex parent.     

‘Give Me a Reason to Live!’ Examining Reasons for Living Across Levels of Suicidality

Scholarly research focusing on social psychological factors (e.g. mental health) and social environmental factors (e.g. childhood trauma) has found these measures to be correlated with suicidality. However, such literature has tended to overlook what may impact one’s reasons for living. Using a sample of over 1,200 students from a Canadian university, the goal of the current study is to empirically test, by employing multivariate nested regression models (by levels of suicidal behaviour), known and relative unknown correlates with reasons for living, with a particular focus on strength of religious faith, which is a well-known predictor for suicidality, but less studied as a reason for living. Results show that, among students with serious suicidal ideation and/or a previous suicide attempt, the strongest predictor for student’s reasons for living was strength of religious faith. Strength of religious faith has seldom been acknowledged or identified as an important measure in assessing one’s reasons to live. These findings have implications for the role of religiosity among suicidality research, especially studies that focus on reasons for living.
