Is there a temporal basis of the word length effect? A response to Service (1998)

Service (1998) carried out a study of the word length effect with Finnish pseudowords in which short and long pseudowords were identical except for the inclusion of certain phonemes differing only in pronunciation length, a manipulation that is impossible in English. She obtained an effect of phonemic complexity but little or no word duration effect per se - a discrepancy from the expectations generated by the well-known working memory model of Baddeley (1986). In the present study using English words, we controlled for phonemic complexity differences by using the same words for the short- and long-word sets, but with instructions inducing shorter or longer pronunciation of the words. We obtained substantial word duration effects. Concerns raised by Service are addressed, and we conclude that both duration and complexity are likely to contribute to the word length effect in serial recall.     

The Impact of Cognitive Diversity on Crisis Negotiations

This paper reports on a series of experiments designed to assess the impact of grouping decision makers by level of cognitive complexity on the outcomes they attain in crisis negotiations. The participants—University of Maryland undergraduates who took roles in a simulated international hostage crisis—used a computer decision support system and a controlled network environment for communications. The goal of the experiments was to better understand the dynamics that lead certain types of groupings to have greater success in negotiations, and that lead certain groups of adversaries to achieve more mutually beneficial outcomes such as compromise and agreement. The findings point to a positive relationship between the level of homogeneity in cognitive complexity among decision makers and the achievement of positive outcomes in crisis negotiations.     

Rights, Wrongs, and Aristotelian Egoism: Illuminating the Rights/Care Dichotomy

Since the recent work of Carol Gilligan, Nel Noddings, and others, it has become commonplace in moral philosophy to employ a dichotomy between an ethics of "Care" and an ethics of "Rights." Gilligan claims that men and women view moral issues in fundamentally divergent ways. Responses to moral problems tend to divide along lines emphasizing respect for rights, in the case of men, and caring for others, in the case of women. Inspired by these findings, several authors have classified moral theories in two basic camps, revolving around the injunction to care or the mandate to respect rights. While many concede that the Care and Rights perspectives are not mutually exclusive, it is increasingly common to view ethicists as forced to choose between these two types of theories.     

Effects of objective self-awareness on attribution of causality

Two experiments were conducted to test the proposition that attribution of causality will be determined by the focus of attention. In Expt I Ss responded to 10 hypothetical situations, each presenting the possibility that either the S or someone else might be the cause of a negative consequence. After each situation was presented, the S was asked to estimate in percentages the extent to which he was causal in bringing about the negative consequence. In order to reduce experimentally the degree of attention focused toward the self, approximately half of the Ss were required to engage in a motor activity while replying to the questions. The procedure of Expt II differed from the first in two respects: (1) There were five hypothetical situations with positive consequences as well as five with negative consequences, and (2) for approximately half of the Ss a stimulus was introduced that would direct their attention to themselves, rather than to the environment. The results of both experiments indicated that attribution of causality to the self was greater when attention was focused on the self, and in the second experiment it was found that this effect operates independently of whether the consequences are good or bad.     

Within‐subject analysis of a prevention strategy for problem behavior

Although decades of research on functional analysis methodology have identified common contingencies that maintain problem behavior and effective interventions, relatively little research has been conducted on strategies to prevent the initial development of problem behavior. We conducted a 2‐part case study, the purposes of which were to illustrate the use of sensitivity tests as the bases for intervention (Study 1) and subsequently to assess the efficacy of a prevention strategy using a single‐subject design (Study 2). Results showed that the sensitivity tests identified establishing operations that may set the occasion for the development of problem behavior and that interventions based on differential reinforcement prevented increases in the severity of problem behavior relative to untreated and control baselines. Benefits and limitations to this individualized approach to prevention are discussed.     

A Note on Recurring Misconceptions When Fitting Nonlinear Mixed Models

Nonlinear mixed-effects (NLME) models are used when analyzing continuous repeated measures data taken on each of a number of individuals where the focus is on characteristics of complex, nonlinear individual change. Challenges with fitting NLME models and interpreting analytic results have been well documented in the statistical literature. However, parameter estimates as well as fitted functions from NLME analyses in recent articles have been misinterpreted, suggesting the need for clarification of these issues before these misconceptions become fact. These misconceptions arise from the choice of popular estimation algorithms, namely, the first-order linearization method (FO) and Gaussian-Hermite quadrature (GHQ) methods, and how these choices necessarily lead to population-average (PA) or subject-specific (SS) interpretations of model parameters, respectively. These estimation approaches also affect the fitted function for the typical individual, the lack-of-fit of individuals’ predicted trajectories, and vice versa.     

A Population-Based Study of Children’s Well-Being and Health: The Relative Importance of Social Relationships,Health-Related Activities,and Income

This study investigated how various risk and protective factors interface with child health and well-being at the population level. Specifically, we examined the association of income, social-contextual variables, and indicators of health-related habits and activities to children’s life satisfaction and perceived overall health. Child data were collected via a self-report survey, the Middle Years Development Instrument, which was administered in three demographically diverse Canadian school districts to 5026 grade 4 students (83 % of the students had complete data and were included in the analyses). Multiple regression and mediation analyses were conducted to examine the joint associations of social relationships with adults and peers, nutrition and sleep habits, and after school sports activities with children’s satisfaction with life and perceived health. Results indicate that peer belonging and relationships with adults at home and school were the strongest predictors of life satisfaction. Furthermore, the (small) association between income and life satisfaction was mediated by social relationship variables. Child reports of perceived health were predicted by peer belonging, adult relationships (home, school, neighborhood), after-school team sports, and nutrition habits. The (small) association between income and health was mediated by social relationships and team sports participation. Findings are discussed in light of previous research on social determinants and socio-economic gradients of children’s health and life satisfaction.     

Whose Side Are You On? Exploring the Role of Perspective Taking on Third-Party’s Reactions to Workplace Deviance

We introduce perspective taking as an antecedent of third-party reactions to different forms of workplace deviance. Varying the perspective taken by third-parties, the target and the type of workplace deviance, we show that third-parties who take the perpetrator’s perspective perceive the incident as less of a moral violation, make less internal, and more external attributions for the perpetrator’s behavior, which in turn reduces endorsement of punishment. Findings were consistent across four studies, and the mediating mechanisms supported by the instrumental variable method and the concurrent double randomization design.
