Twenty-four-hour sleep-wake patterns in a nursing home population

Sleep-activity patterns were objectively recorded over a 24-hr period in 19 elderly nursing home residents. On average, both sleep and wake times were observed during every hour of the 24 recorded hours; however, the sleep pattern of the residents was fragmented so that they rarely experienced even a single hour of consolidated time spent sleeping. It is hypothesized that several independent factors, including compensation for lost sleep, increased total time in bed, weakening of social constraints, and deterioration of the circadian sleep-wake rhythm, are interacting to produce this increase in sleep fragmentation.     

Temporal manipulation of stimulus patterns using the Apple II: Tachistoscopic and part presentation

A technique is described in which line-drawn pictures can be rapidly interlaced, allowing for sequential part presentation or tachistoscopic presentation on the Apple II. This is accomplished using a two-stage process in which the pictorial stimuli are converted into machine code data files and then used to create a rapidly changing display consisting of two or more line drawings. The latter stage could be accomplished in less than 2 msec but is limited by the frame time of the monitor (17–20 msec).     

The Virgin and the Whore – An Interreligious Challenge for Our Times

The boundaries of religious belonging are often based upon essentialist patriarchal conceptions of decency and morality that have been shaped into doctrine; those who are deemed indecent are marginalized to locations of struggle and often met with violence – thus presenting an interreligious challenge for our times. This paper will explore the gendered politics of religious belonging through an intersectional lens, focusing on the virgin/whore dichotomy in Christianity. It aims to undress exclusive notions of religious belonging and expose the hegemonic systems that have created ideological boundaries intended to control the bodies of women. It will then look to the narrative of Tamar and Judah in the book of Genesis, where prostitution, Levirate marriage, widowhood, childbirth, ethnicity, honour killing, and sexual desires shape the text and force the reader to confront questions of morality, justice, and the politics of religious belonging.     

Caregivers’ emotional competence and behavioral responsiveness as correlates of early childcare workers’ relationships with children in their care

In the current study, we examined associations among early childcare workers’ emotional competence, observed responsiveness, comfort with socioemotional teaching practices, and the quality of their relationships with children in their care. The participants were 100 early childcare workers (72 center-based Early Head Start teachers and 28 family childcare providers). Results showed that caregivers’ emotion regulation ability was positively associated with caregiver–child relational closeness. Understanding and regulation of emotion were both positively associated with childcare workers’ comfort with socioemotional teaching practices. Their observed responsiveness was positively related to relational closeness and negatively related to relational conflict. Findings are consistent with aspects of the prosocial classroom model, which asserts that educators high in emotional and social competence tend to adopt childcare practices that result in supportive relationships with children. Results provide insight into whether childcare workers’ responsiveness to young children and their perceived socioemotional teaching practices provide a pathway between emotional competence and the quality of caregiver–child relationships.     

Ethical and Regulatory Considerations for Using Social Media Platforms to Locate and Track Research Participants

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social media to locate and track participants. We offer a rubric that can be used in future studies to determine ethical and regulation-consistent use of social media platforms and illustrate the rubric using our study team’s experience with Facebook. We also offer recommendations for both researchers and institutional review boards that emphasize the importance of well-described procedures for social media use as part of informed consent.     

Slavery in the White Psyche

This article was born out of the hypothesis that slavery—as historical reality, signifier, and symbol—has deep psychological implications for contemporary white Americans. Using data collected in an exploratory, qualitative study, my participants’ responses serve to illuminate the psychic structure of whiteness, which functions as a distortion that gets passed down intergenerationally (and horizontally) through a white collective unconscious. Housed in individual psyches, I suggest that this distorted structure of self actively resists and prevents white Americans (as a collective) from making contact with the racialized realities, both past and present, that would potentially lead to opportunities for choice, reparation, and transformation.     

Contrastive Constraints Guide Explanation‐Based Category Learning

This paper provides evidence for a contrastive account of explanation that is motivated by pragmatic theories that recognize the contribution that context makes to the interpretation of a prompt for explanation. This study replicates the primary findings of previous work in explanation‐based category learning (Williams & Lombrozo, 2010), extending that work by illustrating the critical role of the context in this type of learning. Participants interacted with items from two categories either by describing the items or explaining their category membership. We manipulated the feature overlap between the categories and examined both the explanations generated and acquired knowledge of the categories. Explanations for membership in a given category were influenced by the unprompted contrast category, indicating an important role for contrastive processing in the generation of explanations. The influence of the contrast category was similarly seen in the transfer performance of the participants.
