That’s not my place: The interacting effects of faultlines,subgroup size,and social competence on social loafing behaviour in work groups

Taking a social relations approach to team diversity, we propose that faultlines—hypothetical dividing lines that split a team into relatively homogeneous subgroups—impact the team members’ propensity to exhibit social loafing behaviour. We further propose that this individual-level reaction to the faultline structure of the team can differ among team members, depending on the size of their subgroup and on their individual social competence. We tested the assumptions with a sample of real teams working on an intellective task during which social loafing behaviour was video-coded. In partial support of the hypotheses, generalized mixed models revealed that social loafing behaviour was most common for team members who were part of a team with strong faultlines, who belonged to the larger subgroup in their team, and who exhibited low levels of social competence. The results therefore highlight the benefits of taking a multilevel approach to the effects of faultlines.     

Sense of Competence and Beliefs About Parental Roles in Mothers and Fathers as Predictors of Coparenting and Child Engagement in Mother–Father–Infant Triadic Interactions

The aim of this study was to assess the extent to which a sense of competence and beliefs about parental roles in mothers and fathers influence coparenting and child engagement in triadic interactions during the first 2 years of the child's life, after other influential variables such as marital satisfaction and postpartum depression have been controlled for. The sample constituted 69 mother–father–infant families, whose sense of competence, beliefs in parental roles, postpartum depression, and marital satisfaction were assessed in our laboratory at 3, 9, and 18 months with self‐reported questionnaires. Coparenting support and conflict and child engagement were assessed with the Lausanne Trilogue Play. Results show that (i) predictors of coparenting and child engagement are not the same at each time point; (ii) a sense of competence in mothers is positively linked with coparenting support, particularly at 3 months, whereas in fathers, it is negatively linked with support, particularly at 18 months; (iii) discrepancies between mothers and fathers in beliefs about the importance of the mother's role is the main predictor of coparenting conflict at 18 months; and (iv) paternal beliefs about the importance of the father's and mother's roles are the main predictor of child engagement at 18 months.

帮忙失败后我会被差评吗?好心帮倒忙中的预测偏差

好心帮倒忙事件时有发生, 帮忙失败的施助者往往认为受助者会苛责自己, 因而可能不愿再次提供帮助。这种预测准确吗?通过6个研究( N = 1763), 对比施助者对受助者反应的预测和受助者的实际反应, 发现了施助者在好心帮倒忙时的预测偏差：他们高估了受助者的负面反应。而在帮忙成功时, 施助者未出现预测偏差或预测偏差的强度较弱。导致该预测偏差的原因是, 施助者更为关注自身的能力, 以为受助者也关注自己的能力, 而受助者更为在意施助者的温暖程度。     

What's the Value of Partisan Loyalty? Partisan Ambivalence,Motivated Reasoning,and Correct Voting in U.S. Presidential Elections

Partisans vary in the extent to which they rely on their partisan identities when voting. Are partisans who rely less on their partisan loyalties more likely to vote correctly than those who stick with their partisan intuitions? Research on motivated reasoning suggests so, but research focused on the heuristic value of partisanship implies otherwise. We examine this question using evidence from the ANES Time Series (1972–2004) and 2008 ANES Panel Survey. We find that ambivalent partisans, that is, those less reliant on partisanship when deciding, are generally less likely to vote correctly than univalent partisans, that is, those more reliant on partisanship. These results challenge some of the pessimism concerning the democratic competence of partisans as they imply that partisans engaging in directional reasoning can nevertheless perform their duties at the ballot box at least as well, if not better, than those engaged in more systematic and “rational” modes of decision-making.     

Therapist Interventions and Skills as Predictors of Dropout in Outpatient Psychotherapy

The current study employed machine learning to investigate whether the inclusion of observer-rated therapist interventions and skills in early sessions of psychotherapy improved dropout prediction beyond intake assessments. Patients were treated by postgraduate clinicians at a university outpatient clinic. Psychometric instruments were assessed at intake and therapeutic interventions and skills in the third session were routinely rated by independent observers. After variable preselection, an elastic net algorithm was used to build two dropout prediction models, one including and one excluding observer-rated session variables. The best model included observer-rated variables and was significantly superior to the model including intake variables only. Alongside intake variables, two observer-rated variables significantly predicted dropout: therapist use of feedback and summaries and treatment difficulty. Although not retained in the final prediction model, the observer-rated use of cognitive techniques was also significantly correlated with dropout. Observer ratings of therapist interventions and skills in early sessions of psychotherapy improve predictors of dropout from psychotherapy beyond intake variables alone. Future research could work toward personalizing dropout predictions to the specific dyad, thereby improving their validity and aiding therapists to recognize and react to increased dropout risk.     

Competence and confusion: How stereotype threat can make you a bad judge of your competence

Women tend to have competence doubts for masculine‐stereotyped domains (e.g., math), whereas men tend to think they can handle both feminine‐stereotyped and masculine‐stereotyped domains equally well. We suggest that perhaps women's more frequent experience with stereotype threat can partly explain why. Our results showed that when stereotype threat was primed in high school students (n = 244), there was no relationship between their performance on an academic test (the SweSAT) and their assessment of their performance (how well they did), whereas in a non‐stereotype threat condition, there was a medium‐sized relationship. The effect was similar for both men and women primed with stereotype threat. The results imply that stereotype threat undermines performance assessments.     

Learning to avoid spiders: fear predicts performance,not competence

We used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large (Exps. 1 and 2), spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. However, they hardly managed to do so when the probability differences were small (Exp. 3), and they did not escape from threat more quickly (Exp. 2). In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed.     

How the Abstract Becomes Concrete: Irrational Numbers Are Understood Relative to Natural Numbers and Perfect Squares

Mathematical cognition research has largely emphasized concepts that can be directly perceived or grounded in visuospatial referents. These include concrete number systems like natural numbers, integers, and rational numbers. Here, we investigate how a more abstract number system, the irrationals denoted by radical expressions like , is understood across three tasks. Performance on a magnitude comparison task suggests that people interpret irrational numbers (specifically, the radicands of radical expressions) as natural numbers. Strategy self‐reports during a number line estimation task reveal that the spatial locations of irrationals are determined by referencing neighboring perfect squares. Finally, perfect squares facilitate the evaluation of arithmetic expressions. These converging results align with a constellation of related phenomena spanning tasks and number systems of varying complexity. Accordingly, we propose that the task‐specific recruitment of more concrete representations to make sense of more abstract concepts (referential processing) is an important mechanism for teaching and learning mathematics.     

Robustness of Decision‐Making Competence: Evidence from Two Measures and an 11‐Year Longitudinal Study

Decision‐making competence (DMC) is the ability to follow normative principles when making decisions. In a longitudinal analysis, we examine the robustness of DMC over time, as measured by two batteries of paper‐and‐pencil tasks. Participants completed the youth version (Y‐DMC) at age 19 and/or the adult version (A‐DMC) 11 years later at age 30, as part of a larger longitudinal study. Both measures are composed of tasks adapted from ones used in experimental studies of decision‐making skills. Results supported the robustness of these measures and the usefulness of the construct. Response patterns for Y‐DMC were similar to those observed with a smaller initial sample drawn from the same population. Response patterns for A‐DMC were similar to those observed with an earlier community sample. Y‐DMC and A‐DMC were significantly correlated, for participants who completed both measures, 11 years apart, even after controlling for measures of cognitive ability. Nomological validity was observed in correlations of scores on both tests with measures of cognitive ability, cognitive style, and environmental factors with predicted relationships to DMC, including household socioeconomic status, neighborhood disadvantage, and paternal substance abuse. Higher Y‐DMC and A‐DMC scores were also associated with lower rates of potentially risky and antisocial behaviors, including adolescent delinquency, cannabis use, and early sexual behavior. Thus, the Y‐DMC and A‐DMC measures appear to capture a relatively stable, measurable construct that increases with supportive environmental factors and is associated with constructive behaviors.
