Simple discrimination training with differential responses to establish functional and equivalence classes with preschool children

The present study assessed whether simple discrimination training with differential responses would produce functional and equivalence classes with preschool children. In Experiment 1, we exposed 10 children to simple successive discrimination training in which they had to press different buttons (selection‐based responses). Response 1 (R1) was reinforced only in the presence of A1, B1, or C1, and Response 2 (R2) was reinforced only in the presence of A2, B2, or C2. We assessed the formation of functional classes by training new selection responses in the presence of one member of each class (A1‐R3, A2‐R4) and testing to see if these responses would occur in the presence of other members. Eight children responded consistently with functional class formation. Four of these eight children also responded consistently with the formation of equivalence classes. Experiment 2 investigated whether differential motor responses (i.e., gestures) would improve equivalence class yields. Three of six children showed both functional and equivalence class formation. In general, the results indicate that the simple discrimination procedure with differential responses yielded functional and equivalence class formation.     

Broadening the individual differences lens on party support and voting behavior: Cynicism and prejudice as relevant attitudes referring to modern-day political alignments

Social-cultural and economic-hierarchical ideological attitudes have long been used to explain variation in political partisanship. We propose two additional, stable attitudes (political cynicism and ethnic prejudice) that may help in explaining contemporary political alignments. In a Belgian (N = 509) and Dutch sample (N = 628), we showed that party support can be segmented into four broad families: left, libertarian, traditionalist, and far-right parties. Both studies revealed that social-cultural and economic-hierarchical right-wing attitudes were negatively related to left party support and positively to libertarian, traditionalist and far-right support. Importantly, additional variance was consistently explained by political cynicism (lower libertarian and traditionalist support), ethnic prejudice (lower left support), or both (higher far-right support). Study 2 additionally demonstrated these patterns for self-reported voting.     

Touching the base: heart-warming ads from the 2016 U.S. election moved viewers to partisan tears

Some political ads used in the 2016 U.S. election evoked feelings colloquially known as being moved to tears. We conceptualise this phenomenon as a positive social emotion that appraises and motivates communal relations, is accompanied by physical sensations (including lachrymation, piloerection, chest warmth), and often labelled metaphorically. We surveyed U.S. voters in the fortnight before the 2016 U.S. election. Selected ads evoked the emotion completely and reliably, but in a partisan fashion: Clinton voters were moved to tears by three selected Clinton ads, and Trump voters were moved to tears by two Trump ads. Viewers were much less moved by ads of the candidate they did not support. Being moved to tears predicted intention to vote for the candidate depicted. We conclude that some contemporary political advertising is able to move its audience to tears, and thereby motivates support.     

Considering the role of early discrimination experiences and the parent–child relationship in the development of disruptive behaviors in adolescence

Discrimination has been shown to be related to diminished psychological adjustment and greater risk for substance use when personally experienced by adolescents and when their caregivers experience discrimination. Our research considers the impact of primary caregiver experiences of racial- and socioeconomic-based discrimination in early (age 3–5 years) and late childhood (age 9½) on adolescent disruptive behaviors (age 14) with a large sample of diverse caregiver–child dyads (N = 634). In addition, we examine the potential protective effects of parent–child relationship quality in early and late childhood in buffering the effects of caregiver discrimination on adolescent disruptive behaviors. We also explore possible gender differences in children's vulnerability to engage in disruptive behaviors in the context of caregiver experiences of discrimination. The findings from this study indicate that at trend level, early childhood experiences of primary caregiver discrimination (ages 3–5) predicted adolescent disruptive behaviors, accounting for the effects of more recent (age 9½) caregiver discrimination. In addition, parent–child relationship quality at age 9½ years was found to buffer the effects of late childhood (age 9½) primary caregiver discrimination on adolescent disruptive behaviors for both male and female youth. The findings highlight the need for prevention and intervention techniques that foster healthy and positive primary caregiver–child relationships.     

The Perpetual Outsider: Voices of Black Women Pursuing Doctoral Degrees at Predominantly White Institutions

This qualitative study explored the perceptions and experiences of Black female doctoral students at predominantly White institutions and their impact on academic persistence and overall well‐being. Fifteen Black female doctoral students participated in semistructured interviews, and each one was administered a demographic questionnaire and was extended an opportunity to participate in member checking. All data collected from the semistructured interviews, demographic questionnaires, and member‐checking exercises were analyzed using Black feminist thought as an interpretive lens. Whereas several themes emerged and are discussed in previous articles (Shavers & Moore, 2014a, 2014b), this article focused on the “Perpetual Outsider” theme, comprising the following subthemes: (a) unwelcoming spaces, (b) tokenism, and (c) outsiders at home. Implications are offered based on identity, support systems, and group counseling. Este estudio cualitativo exploró las percepciones y experiencias de estudiantes negras de doctorado en instituciones predominantemente blancas, así como su impacto en la persistencia académica y bienestar general. Quince estudiantes negras de doctorado participaron en entrevistas semiestructuradas, y a cada una de ellas se les administró un cuestionario demográfico y se les ofreció la oportunidad de participar en seguimientos de miembros. Todos los datos recopilados a partir de las entrevistas semiestructuradas, los cuestionarios demográficos y los ejercicios de seguimiento de miembros fueron analizados e interpretados desde la perspectiva del pensamiento feminista negro. Aunque surgieron varios temas que se comentan en artículos anteriores (Shavers & Moore, 2014a, 2014b), este artículo se centra en el tema del “Forastero perpetuo”, que incluye los siguientes subtemas: (a) espacios hostiles, (b) representación simbólica y (c) forasteros en casa. Se ofrecen implicaciones basadas en la identidad, sistemas de apoyo y consejería de grupo.     

Confidence and decision type under matched stimulus conditions: overconfidence in perceptual but not conceptual decisions

Within the domain of metacognition, there is disagreement whether different processes underlie evaluations of confidence in perceptual versus conceptual decisions. The relationship between confidence and accuracy for perceptual and conceptual decisions was compared using newly created stimuli that could be used to elicit either decision type. Based on theories of Brunswikian and Thurstonian uncertainties, significant underconfidence for perceptual decisions and overconfidence for conceptual decisions were predicted. Three within‐subjects experiments did not support this hypothesis. Participants showed significant overconfidence for perceptual decisions and no overconfidence for conceptual decisions. In addition, significant hard‐easy effects were consistently found for both decision types. Incorporating our findings with past results reveals that both over‐ and underconfidence are attainable on perceptual tasks. This conclusion, in addition to the common presence of hard‐easy effects and significant across‐task correlations in over/underconfidence, suggests that confidence judgments for the two decision types may depend on largely shared processes. Possible contributions to confidence and over/underconfidence are explored, focusing on response time factors and participants' knowledge bases. Copyright © 2007 John Wiley & Sons, Ltd.     

Idealizations and Concretizations in Laws and Explanations in Physics

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation, as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J. Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

Moral Conviction and Political Engagement

The 2004 presidential election led to considerable discussion about whether moral values motivated people to vote, and if so, whether it led to a conservative electoral advantage. The results of two studies—one conducted in the context of the 2000 presidential election, the other in the context of the 2004 presidential election—indicated that stronger moral convictions associated with candidates themselves and attitudes on issues of the day uniquely predicted self-reported voting behavior and intentions to vote even when controlling for a host of alternative explanations (e.g., attitude strength, strength of party identification). In addition, we found strong support for the hypothesis that moral convictions equally motivated political engagement for those on the political right and left and little support for the notion that a combination of morality and politics is something more characteristic of the political right than it is of the political left.     

Cerebellar patients demonstrate preserved implicit knowledge of association strengths in musical sequences

Recent findings suggest the involvement of the cerebellum in perceptual and cognitive tasks. Our study investigated whether cerebellar patients show musical priming based on implicit knowledge of tonal-harmonic music. Participants performed speeded phoneme identification on sung target chords, which were either related or less-related to prime contexts in terms of the tonal-harmonic system. As groups, both cerebellar patients and age-matched controls showed facilitated processing for related targets, as previously observed for healthy young adults. The outcome suggests that an intact cerebellum is not mandatory for accessing implicit knowledge stored in long-term memory and for its influence on perception. One patient showed facilitated processing for less-related targets (suggesting sensory priming). The findings suggest directions for future research on auditory perception in cerebellar patients to further our understanding of cerebellar functions.     

Challenges to providing a support group for HIV-positive prisoners in South Africa

In prison populations around the world, the prevalence of HIV is often higher than that of the general population. The prison population is at high risk for HIV infection, particularly through the sharing of contaminated needles and high-risk sexual activity. Counselling is regarded as a key element in the prevention and treatment of HIV infection. Support groups provide essential supportive counselling for HIV-positive individuals struggling to cope. This paper looks at the challenges to providing a support group for HIV-positive prisoners. The author's experience of attempting to provide a support group highlights two key challenges: organisational issues which lead to disruptions for the group; and challenges to ensuring confidentiality, a core ethical principle in HIV counselling.
