The triangle of interpersonal models

This article develops a framework for social psychology, the triangle of interpersonal models (TIM). TIM is a 2-dimensional classification scheme for the impact of people on social-psychological phenomena. TIM classifies a social-psychological phenomenon by the number of people who contribute to the phenomenon and the number of distinct social-psychological functions that those people serve. TIM includes models for phenomena that involve 1 person, 2 people, 3 people, and p people. In those phenomena, people serve 1, 2, 3, or f distinct social-psychological functions. TIM decomposes complex phenomena into components that reflect different levels of interpersonal causation. It brings rigor to holistic conceptions of social psychology and offers a fresh perspective on the relationship between the individual and the group.     

Toward a racial abyss: eugenics,Wickliffe Draper,and the origins of The Pioneer Fund

The Pioneer Fund was created in 1937 "to conduct or aid in conducting study and research into problems of heredity and eugenics . . . and problems of race betterment with special reference to the people of the United States." The Fund was endowed by Colonel Wickliffe Preston Draper, a New England textile heir, and perpetuates his legacy through an active program of grants, some of the more controversial in aid of research on racial group differences. Those presently associated with the Fund maintain that it has made a substantial contribution to the behavioral and social sciences, but insider accounts of Pioneer's history oversimplify its past and smooth over its more tendentious elements. This article examines the social context and intellectual background to Pioneer's origins, with a focus on Col. Draper himself, his concerns about racial degeneration, and his relation to the eugenics movement. In conclusion, it evaluates the official history of the fund.     

Lower level mediation in multilevel models

Multilevel models are increasingly used to estimate models for hierarchical and repeated measures data. The authors discuss a model in which there is mediation at the lower level and the mediational links vary randomly across upper level units. One repeated measures example is a case in which a person's daily stressors affect his or her coping efforts, which affect his or her mood, and both links vary randomly across persons. Where there is mediation at the lower level and the mediational links vary randomly across upper level units, the formulas for the indirect effect and its standard error must be modified to include the covariance between the random effects. Because no standard method can estimate such a model, the authors developed an ad hoc method that is illustrated with real and simulated data. Limitations of this method and characteristics of an ideal method are discussed.     

Why inference to the best explanation doesn’t secure empirical grounds for mathematical platonism

Proponents of the explanatory indispensability argument for mathematical platonism maintain that claims about mathematical entities play an essential explanatory role in some of our best scientific explanations. They infer that the existence of mathematical entities is supported by way of inference to the best explanation from empirical phenomena and therefore that there are the same sort of empirical grounds for believing in mathematical entities as there are for believing in concrete unobservables such as quarks. I object that this inference depends on a false view of how abductive considerations mediate the transfer of empirical support. More specifically, I argue that even if inference to the best explanation is cogent, and claims about mathematical entities play an essential explanatory role in some of our best scientific explanations, it doesn’t follow that the empirical phenomena that license those explanations also provide empirical support for the claim that mathematical entities exist.

Context and Perceptual Salience Influence the Formation of Novel Stereotypes via Cumulative Cultural Evolution

We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions—color, movement, and shape—thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that described it (e.g., arrogant, caring, confident). Participants were given training on the alien‐attribute assignments and were then tested on their memory for these. The alien‐attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype‐like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., 2014 which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information.
