Factors affecting withdrawal from an escalating conflict: Quitting before it's too late

In an experimental study of “entrapping” conflicts —situations in which a decisionmaker may continue to expend resources in part to justify previous expenditures—subjects were given an initial stake of $4.00 and had the opportunity to win an additional $2.00 jackpot. Two independent variables (Process of Resource Allocation and Prior Limit-Setting) were combined in a 2 × 3 design. Once the subjects had started to invest, half of them had to make an “active” decision to continue. Unless they actively decided to continue, their investments automatically ceased and they were no longer eligible for the jackpot (Selfterminating condition). The other half only had to make a “passive” decision to continue. Unless they actively decided to dis continue, their investments for the jackpot automatically increased (Self-sustaining condition). In addition, before investments began, some subjects were asked to inform the experimenter of the nonbinding limit they had set on the amount they planned to invest (Public condition), some were asked to set a limit which they kept to themselves (Private condition), while a third group was not asked to set a limit (Control condition). Subjects invested significantly more money in the Self-sustaining condition. Also, investments were somewhat greater in the Control than the Public condition. Although the mean investments in the Public and Private conditions did not differ, those in the Public condition deviated significantly less from their earlier set limits, suggesting greater commitment to these limits. Theoretical and practical implications are discussed.     

Infant attachment security and maternal predictors of early behavior problems: A longitudinal study of low-income families

In a longitudinal study of 100 low-income, mother-infant dyads, assessments of infant attachment security and maternal responsivity, involvement, depressive symptomatology, and perceived infant difficulty were used to predict later behavior problems at age 3. Attachment insecurity was related to behavior problems at age 3 when all insecure classifications were combined into one group and when insecurity was maintained at 12 and 18 months. For boys only, maternal depressive symptoms and low maternal involvement were associated with age 3 behavior problems. For girls, perceived difficult temperament at ages 1 and 2 were associated with later problem behavior.     

The Socratic Augustine

Augustine is both one of the great dogmatic thinkers in our Western tradition and also one of the most Socratic. How can that be? I suggest that Augustine is given to puzzling over questions of the form “How is it possible that p?”– for example, “How is it possible to measure time when no length of time is ever present to be measured?” Moreover, he asks questions of this form even when he is in no doubt that p is the case. (Thus he is in no doubt that we can measure periods of time even though, strictly speaking, no period of time is ever present.) I suggest further that we can learn something about good teaching from studying Augustine's Socratic-style inquiry.     

Beyond family‐level adversities: Exploring the developmental timing of neighborhood disadvantage effects on the brain

A growing literature suggests that adversity is associated with later altered brain function, particularly within the corticolimbic system that supports emotion processing and salience detection (e.g., amygdala, prefrontal cortex [PFC]). Although neighborhood socioeconomic disadvantage has been shown to predict maladaptive behavioral outcomes, particularly for boys, most of the research linking adversity to corticolimbic function has focused on family‐level adversities. Moreover, although animal models and studies of normative brain development suggest that there may be sensitive periods during which adversity exerts stronger effects on corticolimbic development, little prospective evidence exists in humans. Using two low‐income samples of boys (n = 167; n = 77), Census‐derived neighborhood disadvantage during early childhood, but not adolescence, was uniquely associated with greater amygdala, but not PFC, reactivity to ambiguous neutral faces in adolescence and young adulthood. These associations remained after accounting for several family‐level adversities (e.g., low family income, harsh parenting), highlighting the independent and developmentally specific neural effects of the neighborhood context. Furthermore, in both samples, indicators measuring income and poverty status of neighbors were predictive of amygdala function, suggesting that neighborhood economic resources may be critical to brain development.     

No Harm,Still Foul: Concerns About Reputation Drive Dislike of Harmless Plagiarizers

Across a variety of situations, people strongly condemn plagiarizers who steal credit for ideas, even when the theft in question does not appear to harm anyone. Why would people react negatively to relatively harmless acts of plagiarism? In six experiments, we predict and find that these negative reactions are driven by people's aversion toward agents who attempt to falsely improve their reputations. In Studies 1–3, participants condemn plagiarism cases that they agree are harmless (i.e., stealing credit from an anonymous source). This effect is mediated by the extent to which participants perceive the plagiarizer to have falsely benefitted from plagiarizing. In Studies 4–5, we demonstrate that this effect is not explained solely by participants’ negative response to lies or violations of permission. In Study 6, participants condemn a plagiarism case in which the idea's original author actually benefits, providing the strongest evidence that people condemn plagiarism for reasons beyond perceived harm. We discuss how this work connects to broader questions of intellectual property and impression management.
