Participant Retention in the Parents Matter! Program: Strategies and Outcome

We present a discussion of the literature addressing retention of ethnic minority samples in longitudinal studies. In addition, we describe the retention procedures implemented in the Parents Matter! Program (PMP), a community-based sexual risk reduction intervention for African American families. Finally, the results of PMP's retention strategies are presented.     

Open Theism: An Answer to My Critics

Abstract :  Open theism is a version of historic free will theism which posits God as granting to human beings significant freedom to cooperate with or to resist the will of God for their lives. God's goal is to make possible relationships of mutual love between God and creatures and therefore set up a dynamic give and take situation in which God can even be said to risk failure to the degree permitted by the overall plan. A debate has broken out as to whether open theism goes too far in its revision. I myself see it as a mere adjustment to standard Arminian thinking on the point of understanding the divine foreknowledge. In this article, I argue that, despite a goodly number of objections, the position deserves to be viewed as a legitimate option for Christian theology, yea even for "evangelical" theology.     

Perceptions of Self and of Ideal Mates: Similarities and Differences across the Sexes

For 19 mating-relevant traits, single males (N= 53) and single females (N= 86) rated (a) themselves relative to their same-sex peers, (b) their perceptions of the qualities desired by members of the opposite sex in an ideal partner, and (c) the qualities desired in their own ideal romantic partner. Several themes emerged from the data. First, males’ and females’ judgments of what members of the opposite-sex seek were generally accurate. Second, males and females both feel that they fall short of perceived opposite-sex expectations in a few areas. Third, both males and females desire an ideal partner better than themselves, but this is especially true for females. These findings are discussed in terms of evolutionary social psychological principles.     

I get so lonely,baby: The effects of loneliness and social isolation on romantic dependency

Individuals lacking fulfilling interpersonal interactions may experience feelings of loneliness. Consequently, these individuals may over-rely on their romantic partners to fulfill the need to belong. This study examined the effects of loneliness and social isolation on dependency on a romantic partner in a sample of college students (N = 104). Participants who were in a romantic relationship completed measures of loneliness, social isolation, and romantic dependency near the beginning of the semester (Time 1) and approximately 6 weeks later toward the end of the semester (Time 2). Toward the beginning of the semester, there were no significant predictors of dependency. Toward the end of the semester, individuals who reported higher social isolation reported higher levels of dependency. Time 1 dependency also predicted Time 2 dependency. Future methodological directions and suggestions regarding the examination of perceptions of loneliness and relationship expectations are discussed.     

Grammaticality,Acceptability, and Probability: A Probabilistic View of Linguistic Knowledge

The question of whether humans represent grammatical knowledge as a binary condition on membership in a set of well‐formed sentences, or as a probabilistic property has been the subject of debate among linguists, psychologists, and cognitive scientists for many decades. Acceptability judgments present a serious problem for both classical binary and probabilistic theories of grammaticality. These judgements are gradient in nature, and so cannot be directly accommodated in a binary formal grammar. However, it is also not possible to simply reduce acceptability to probability. The acceptability of a sentence is not the same as the likelihood of its occurrence, which is, in part, determined by factors like sentence length and lexical frequency. In this paper, we present the results of a set of large‐scale experiments using crowd‐sourced acceptability judgments that demonstrate gradience to be a pervasive feature in acceptability judgments. We then show how one can predict acceptability judgments on the basis of probability by augmenting probabilistic language models with an acceptability measure. This is a function that normalizes probability values to eliminate the confounding factors of length and lexical frequency. We describe a sequence of modeling experiments with unsupervised language models drawn from state‐of‐the‐art machine learning methods in natural language processing. Several of these models achieve very encouraging levels of accuracy in the acceptability prediction task, as measured by the correlation between the acceptability measure scores and mean human acceptability values. We consider the relevance of these results to the debate on the nature of grammatical competence, and we argue that they support the view that linguistic knowledge can be intrinsically probabilistic.     

Profiles of Children’s Thinking About Violence in Families Exposed to Intimate Partner Violence

Intimate partner violence remains a pervasive and common social problem. Evidence indicates that children witness many instances of intimate partner violence. However, the structure of children’s thinking about family violence is still not well understood. This research employed latent profile analysis to identify underlying latent profiles of children’s thinking about violence using the Attitudes and Beliefs About Violence Scale. The analysis identified two latent profiles mostly differentiated by children’s beliefs about whether or not victims of violence deserve to have violence inflicted upon them. Several covariates differentiated members of the two profiles. Suggestions for intervention and practice are included.     

Serotonin enhances the impact of health information on food choice

Serotonin has been implicated in promoting self-control, regulation of hunger and physiological homeostasis, and regulation of caloric intake. However, it remains unclear whether the effects of serotonin on caloric intake reflect purely homeostatic mechanisms, or whether serotonin also modulates cognitive processes involved in dietary decision making. We investigated the effects of an acute dose of the serotonin reuptake inhibitor citalopram on choices between food items that differed along taste and health attributes, compared with placebo and the noradrenaline reuptake inhibitor atomoxetine. Twenty-seven participants attended three sessions and received single doses of atomoxetine, citalopram, and placebo in a double-blind randomised cross-over design. Relative to placebo, citalopram increased choices of more healthy foods over less healthy foods. Citalopram also increased the emphasis on health considerations in decisions. Atomoxetine did not affect decision making relative to placebo. The results support the hypothesis that serotonin may influence food choice by enhancing a focus on long-term goals. The findings are relevant for understanding decisions about food consumption and also for treating health conditions such as eating disorders and obesity.
