Differential Daily Writing Contingencies and Performance on Major Multiple-Choice Exams

On 4 of 7 days in each unit of an undergraduate human development course, students responded in writing to specific questions related to instructor notes previously made available to them. The study compared the effects of three writing contingencies on the quality of student writing and performance on major multiple-choice exams in the course. The three contingencies were (1) receiving credit for all writing products each unit, (2) receiving credit for one randomly selected writing product each unit, and (3) receiving no credit for any writing product each unit. On all dimensions of exam performance, writing for daily credit produced higher scores than did writing for random credit and writing for no credit. The daily-writing contingency also produced the highest writing ratings across all units; the writing for random credit produced the next highest writing scores; and the writing for no credit yielded the lowest writing scores. Across all three contingencies, writing scores were highly correlated with performance on multiple-choice exams.     

RETRACTED ARTICLE: Losing control: Mostly incongruent lists postpone,but do not eliminate,the Stroop effect

Identifying the color (e.g., red) of a color word that is incongruent (e.g., “BLUE”) can be remarkably difficult. The Stroop effect is a measure of the interference between activity from word and color pathways. The efficacy of these pathways is thought to be highly contingent on the frequency of incongruent trials within a block. A block of trials with mostly incongruent (MI) trials typically results in a smaller Stroop effect than a block with mostly congruent (MC) trials. This reduction of the Stroop effect has been largely attributed to the strategic list-wide control of the word pathway. Here, the time course of the Stroop effect was explored using speed-accuracy tradeoff functions (SATfs) in tasks with 50 % congruent, MC, and MI trials. In the MC and 50 % congruent condition, color-word congruency affected the rate parameter of the SATf. In the MI condition, however, congruency affected the asymptote. This evidence is consistent with the idea that the strategic control of the word pathway is an effortful, temporary phenomenon, prone to buckle if responding is held in check.     

Social protest photography and public history: “Whose streets? Our streets!”: New York City, 1980–2000

“Whose streets? Our streets!,” a traveling exhibition that debuted at the Bronx Documentary Center in January 2017, brings together the work of 37 independent photographers who covered protests in New York City between 1980 and 2000. Collectively, they chronicle social justice struggles related to race relations and police brutality; war and the environment; HIV/AIDS and queer activism; abortion rights, feminism, and the culture wars; and housing, education, and labor. The exhibition and companion multimedia website demonstrate the role that photographers, activists, and ordinary people play in enacting democratic social change. They also highlight social protest photography as an important source for doing public history.     

Reactive and proactive aggression as meaningful distinctions at the variable and person level in primary school‐aged children

Reactive and proactive aggression is a dichotomous classification of aggression in adults and children. This distinction has been supported by a number of variable‐based and factor analytic studies. Due to high inter‐correlations, however, the reactive—proactive aggression distinction may not be entirely useful for understanding how group or individual aggressive behavior varies in children and adolescents. Drawing on a sample of primary school‐aged children (N = 242) aged 7–12 years, this study sought to determine whether reactive and proactive aggression could be distinguished at the variable‐level and the person‐level in children. Exploratory Factor Analysis of data from an aggression instrument measuring both functions and forms of aggression, found a two‐factor construct of aggression constituted by a reactive and proactive aggression factor. A person‐based analysis was then conducted after classifying children according to the presence of reactive and/or proactive aggression. Discriminant function analysis was used to discern whether classifications on the basis of aggression function produced meaningful distinctions in terms of antisocial traits and emotional valence and intensity measures. Two functions were identified which distinguished children with different combinations of reactive and proactive aggression. Reactive‐only aggressive children were defined primarily by high levels of impulsivity, while proactive‐only children were defined primarily by higher levels of antisocial traits. Children high in both types of aggression exhibited both the presence of antisocial traits and impulsivity. Contrary to recent findings, this suggests that differences in aggression functions remain meaningful at the person level in children. Implications for interventions are discussed.
