Self-Verification as a Mediator of Mothers’ Self-Fulfilling Effects on Adolescents\u27 Educational Attainment

This research examined whether self-verification acts as a general mediational process of self-fulfilling prophecies. The authors tested this hypothesis by examining whether self-verification processes mediated self-fulfilling prophecy effects within a different context and with a different belief and a different outcome than has been used in prior research. Results of longitudinal data obtained from mothers and their adolescents (N = 332) indicated that mothers’ beliefs about their adolescents’ educational outcomes had a significant indirect effect on adolescents’ academic attainment through adolescents’ educational aspirations. This effect, observed over a 6-year span, provided evidence that mothers’ self-fulfilling effects occurred, in part, because mothers’ false beliefs influenced their adolescents’ own educational aspirations, which adolescents then self-verified through their educational attainment. The theoretical and applied implications of these findings are discussed

Self‐fulfilling Prophecies: Mechanisms, Power, and Links to Social Problems

A core theme of social psychology is that perceivers can shape targets’ future behaviors through self-fulfilling prophecies. Self-fulfilling prophecies occur when perceivers’ false beliefs about targets initiate a sequence of events that ultimately cause targets to exhibit expectancy-consistent behaviors, thereby causing perceivers’ initially false beliefs to become true. This article reviews theory and research relevant to self-fulfilling prophecies with particular foci on the underlying mechanisms that produce self-fulfilling prophecies, the power of self-fulfilling prophecies to alter behavior, and the extent to which self-fulfilling prophecies contribute to social problems

Universal Intervention as a Protective Shield Against Exposure to Substance Use: Long-Term Outcomes and Public Health Significance

Objectives. We examined universal preventive intervention effects on adolescents' exposure to opportunities for substance use and on illicit substance use in the long term

Six-Year Sustainability of Evidence-Based Intervention Implementation Quality by Community-University Partnerships: The PROSPER Study

There is a knowledge gap concerning how well community-based teams fare in implementing evidence-based interventions (EBIs) over many years, a gap that is important to fill because sustained high quality EBI implementation is essential to public health impact. The current study addresses this gap by evaluating data from PROSPER, a community-university intervention partnership model, in the context of a randomized-control trial of 28 communities. Specifically, it examines community teams’ sustainability of implementation quality on a range of measures, for both family-focused and school-based EBIs. Average adherence ratings approached 90% for family-focused and school-based EBIs, across as many as 6 implementation cohorts. Additional indicators of implementation quality similarly showed consistently positive results. Correlations of the implementation quality outcomes with a number of characteristics of community teams and intervention leaders were calculated to explore their potential relevance to sustained implementation quality. Though several relationships attained statistical significance at particular points in time, none were stable across cohorts. The role of PROSPER’s continuous, proactive technical assistance in producing the positive results is discussed

Validity of forensic cartridge-case comparisons

This article presents key findings from a research project that evaluated the validity and probative value of cartridge-case comparisons under field-based conditions. Decisions provided by 228 trained firearm examiners across the US showed that forensic cartridge-case comparison is characterized by low error rates. However, inconclusive decisions constituted over one-fifth of all decisions rendered, complicating evaluation of the technique’s ability to yield unambiguously correct decisions. Specifically, restricting evaluation to only the conclusive decisions of identification and elimination yielded true-positive and true-negative rates exceeding 99%, but incorporating inconclusives caused these values to drop to 93.4% and 63.5%, respectively. The asymmetric effect on the two rates occurred because inconclusive decisions were rendered six times more frequently for different-source than same-source comparisons. Considering probative value, which is a decision’s usefulness for determining a comparison’s ground-truth state, conclusive decisions predicted their corresponding ground-truth states with near perfection. Likelihood ratios (LRs) further showed that conclusive decisions greatly increase the odds of a comparison’s ground-truth state matching the ground-truth state asserted by the decision. Inconclusive decisions also possessed probative value, predicting different-source status and having a LR indicating that they increase the odds of different-source status. The study also manipulated comparison difficulty by using two firearm models that produce dissimilar cartridge-case markings. The model chosen for being more difficult received more inconclusive decisions for same-source comparisons, resulting in a lower true-positive rate compared to the less difficult model. Relatedly, inconclusive decisions for the less difficult model exhibited more probative value, being more strongly predictive of different-source status.This article is published as Guyll, M., Madon, S., Yang, Y., Burd, K.A., Wells, G., Validity of forensic cartridge-case comparisons, Psychological and Cognitive Sciences., May 2023, 120 (20);e2210428120.; https://doi.org/10.1073/pnas.221042812Copyright © 2023 the Author(s).

The Accumulating Effects of Shared Expectations

This research examined whether self-fulfilling prophecies and perceptual confirmation effects accumulated across people. Trios of same-sex participants, each consisting of two interviewers and one target, were randomly assigned to one of three conditions that served to manipulate interviewers\u27 expectations (i.e., non-hostile vs. hostile) and the similarity of their expectations (i.e., similar vs. dissimilar) for targets. Each trio participated in an interaction in which interviewers asked targets questions. Targets\u27 hostility during the interaction and interviewers\u27 impressions of targets\u27 hostility following the interaction served as the primary dependent variables. Results indicated that perceptual confirmation effects accumulated across interviewers. Even though targets\u27 behavior during the interaction did not differ across conditions, interviewers nonetheless judged targets as more hostile when both interviewers expected targets to be hostile than when only one did. The authors discuss these findings in terms of the potential implications for those who have multiple inaccurate and unfavorable expectations held about them
