Speaking two “Languages” in America: A semantic space analysis of how presidential candidates and their supporters represent abstract political concepts differently

In this article we report a computational semantic analysis of the presidential candidates’ speeches in the two major political parties in the USA. In Study One, we modeled the political semantic spaces as a function of party, candidate, and time of election, and findings revealed patterns of differences in the semantic representation of key political concepts and the changing landscapes in which the presidential candidates align or misalign with their parties in terms of the representation and organization of politically central concepts. Our models further showed that the 2016 US presidential nominees had distinct conceptual representations from those of previous election years, and these patterns did not necessarily align with their respective political parties’ average representation of the key political concepts. In Study Two, structural equation modeling demonstrated that reported political engagement among voters differentially predicted reported likelihoods of voting for Clinton versus Trump in the 2016 presidential election. Study Three indicated that Republicans and Democrats showed distinct, systematic word association patterns for the same concepts/terms, which could be reliably distinguished using machine learning methods. These studies suggest that given an individual’s political beliefs, we can make reliable predictions about how they understand words, and given how an individual understands those same words, we can also predict an individual’s political beliefs. Our study provides a bridge between semantic space models and abstract representations of political concepts on the one hand, and the representations of political concepts and citizens’ voting behavior on the other.     

The K-factor: Individual differences in life history strategy

Until recently, variations in life history strategy were studied exclusively at the species level. Although this domain of study has been extended to examine systematic differences in life history strategy among various human ethnic groupings, more recent evolutionary theories of human development and related behavioral genetic work imply substantial within-group individual variation in life history strategy. We constructed a latent variable model identifying a single common factor, denoted as K, which underlies a variety of otherwise disparate life history parameters. This “K-Factor” loaded 0.36 on childhood attachment to the biological father, −0.36 on childhood attachment to any non-biological father figure, 0.38 on adult romantic partner attachment, −0.51 on mating effort, −0.58 on Machiavellianism, and −0.41 on risk propensity. The bivariate correlations of the K-factor with higher-order personality factors were statistically significant, −0.24 with “Big Neuroticism” and −0.67 with “Big Psychoticism”, and approached significance, correlating 0.12, with “Big Extraversion”. The K-factor appears to be an underappreciated individual difference variable of major importance to human development.     

Against dispositionalism: belief in cognitive science

Dispositionalism about belief has had a recent resurgence. In this paper we critically evaluate a popular dispositionalist program pursued by Eric Schwitzgebel. Then we present an alternative: a psychofunctional, representational theory of belief. This theory of belief has two main pillars: that beliefs are relations to structured mental representations, and that the relations are determined by the generalizations under which beliefs are acquired, stored, and changed. We end by describing some of the generalizations regarding belief acquisition, storage, and change.     

Personal Therapy and Self-Care in the Making of Psychologists

Abstract

Psychologists are skilled in assessing, researching, and treating patients’ distress, but frequently experience difficulty in applying these talents to themselves. The authors offer 13 research-supported and theoretically neutral self-care strategies catered to psychologists and those in training: valuing the person of the psychologist, refocusing on the rewards, recognizing the hazards, minding the body, nurturing relationships, setting boundaries, restructuring cognitions, sustaining healthy escapes, maintaining mindfulness, creating a flourishing environment, cultivating spirituality and mission, fostering creativity and growth, and profiting from personal therapy. The latter deserves special emphasis in the making of health care psychologists. These strategies are recommended both during training and throughout the career span. Recommendations are offered for enhancing and publicizing systems of self-care throughout the profession.     

Treating Couples Raising Children on the Autism Spectrum: A Marriage-Friendly Approach

Available research demonstrates that autism spectrum disorders (ASDs) affect couples in a variety of different ways. Some partners draw closer to one another through the experience of caring for a child on the autism spectrum while others experience relationship dissatisfaction, separation, and divorce. Yet other research reveals that many couples raising children with ASDs may experience an initial dip in relationship satisfaction but, after adjusting to a new way of life and developing new expectations for their children, are later able to bond in novel ways. Thus, a marriage-friendly approach to therapy, which focuses on helping partners remain committed to each other through the trials and tribulations of life, may allow these couples to work through the difficulties of raising children on the autism spectrum without resorting to separation or divorce. Ethical implications of a marriage-friendly approach to therapy with couples raising children with ASDs are also considered.     

Divine Hiddenness: Would More Miracles Solve the Problem?

This article addresses the question of whether God's existence would be obvious to everyone if God performed more miracles. I conclude that it would not be so. I look at cases where people have been confronted with what they believe to be miracles and have either not come to believe in God, or have come to intellectual belief in God but declined to follow him. God's existence could be made undeniable not by spectacular signs, but only by God impressing his existence upon us in a direct, non‐propositional way.     

Similarities between the irrelevant sound effect and the suffix effect

Although articulatory suppression abolishes the effect of irrelevant sound (ISE) on serial recall when sequences are presented visually, the effect persists with auditory presentation of list items. Two experiments were designed to test the claim that, when articulation is suppressed, the effect of irrelevant sound on the retention of auditory lists resembles a suffix effect. A suffix is a spoken word that immediately follows the final item in a list. Even though participants are told to ignore it, the suffix impairs serial recall of auditory lists. In Experiment 1, the irrelevant sound consisted of instrumental music. The music generated a significant ISE that was abolished by articulatory suppression. It therefore appears that, when articulation is suppressed, irrelevant sound must contain speech for it to have any effect on recall. This is consistent with what is known about the suffix effect. In Experiment 2, the effect of irrelevant sound under articulatory suppression was greater when the irrelevant sound was spoken by the same voice that presented the list items. This outcome is again consistent with the known characteristics of the suffix effect. It therefore appears that, when rehearsal is suppressed, irrelevant sound disrupts the acoustic-perceptual encoding of auditorily presented list items. There is no evidence that the persistence of the ISE under suppression is a result of interference to the representation of list items in a postcategorical phonological store.     

Spontaneous Focusing on Quantitative Relations in the Development of Children's Fraction Knowledge

While preschool-aged children display some skills with quantitative relations, later learning of related fraction concepts is difficult for many students. We present two studies that investigate young children's tendency of Spontaneous Focusing On quantitative Relations (SFOR), which may help explain individual differences in the development of fraction knowledge. In the first study, a cross-sectional sample of 84 kindergarteners to third graders completed tasks measuring their spontaneous recognition and use of quantitative relations and then completed the tasks again with explicit guidance to focus on quantitative relations. Findings suggest that SFOR is a measure of the spontaneous focusing of attention on quantitative relations and the use of these relations in reasoning. In the second (longitudinal) study, 25 first graders completed measures of SFOR tendency and a measure of fraction knowledge three years later. SFOR tendency was found to predict fraction knowledge, suggesting that it plays a role in the development of fraction knowledge.
