What Experiences Do Expository Books on Recommended Book Lists Offer to K–2 Students?

Teachers can use expository texts to teach academic vocabulary, content knowledge, text structure, and text features. National associations' recommended book lists are often used to identify books for classrooms. Previously we identified expository texts on these lists from 2001–2002 and 2011–2012. The current study explored instructional possibilities these expository books afford. More recent books have more content, academic vocabulary, and supplementary information. However, many earlier and recent books lack text features such as page numbers, tables of contents, glossaries, and indexes. Teachers will need to supplement these books with other texts to provide experiences enabling proficiency with exposition.     

Reply to Janine de Peyer’s “Traversing the Ineffable: Commentary on Sharon Farber’s ‘Becoming a Telepathic Tuning Fork’”

Janine de Peyer’s thoughtful and stimulating response to my paper evoked a good deal of thinking about playfulness and creativity in doing psychotherapy, what part intuition and empathy play in promoting telepathic communication, the distinction between thoughts and feelings unconsciously transmitted between people within close proximity and those transmitted across geographical distance, where there is no reliance on sensory clues involving sight, sound, smell, touch, and taste. De Peyer’s summary of research on telepathy tells us that most of the research tries to rule out the variable of unconscious sensory exchange by physically separating the “sender” from the “receiver.”

In her discussion of my paper, Janine de Peyer raises some very interesting questions about how telepathy is to be defined. I recall reading years ago about someone who had gone to a medium and heard some startling information about herself and those in her circle. As I wondered how the medium could know so much about someone she had never before met, it occurred to me that there was a lot of knowledge about a person conveyed by the brain-to-brain sensory cues, and this was not telepathic but more a function of intuition and empathy. I think that was true about the relationship I had with my patient. but as with the medium there was a lot of other information I received about her that did not depend on sensory cues, and that information was, I believe, conveyed telepathically. So yes, I say, to de Peyer’s (this issue) question, “Is it not worth differentiating between in-session heightened intuitive receptiveness, and unexplainable transmissions of affect/thoughts/information that traverse time and geographical space?” (p. 736, italics in the original). In considering the time spent in my patient’s physical presence, much of my empathic attunement originated from the intuitive response that was induced in me by her physical presence. I think the increasing empathic attunement laid the foundation for subsequent telepathic communication.     

Is Obstructive Sleep Apnoea Related to Neuropsychological Function in Healthy Older Adults? A Systematic Review and Meta-Analysis

Previous systematic reviews and meta-analyses have identified cognitive deficits in adults with obstructive sleep apnoea (OSA). However, quantitative analysis of the association between OSA and neuropsychological performance has not been conducted specifically in older adults, for whom there is a greater risk of cognitive decline. We searched Medline, Embase and PsycINFO through August 2016 for studies describing associations between OSA and neuropsychological outcomes in people aged>50 years. Meta-analyses were performed on these studies for overall cognition and within cognitive domains. Subgroup analyses were performed taking into account risk of bias and moderating differences in study design. 13 studies met eligibility criteria for analysis. A small negative association was found between OSA and all neuropsychological outcomes combined, g=0.18(95% CI 0.04–0.32), and in memory and processing speed domains. Small case-control studies from sleep clinic populations observed the greatest associations, while larger cohort studies from community samples illustrated no association. Analysis accounting for publication bias resulted in a null overall association, g=0.02 (95%CI -0.12 to 0.16). Associations between OSA and cognition in later life are highly variable and the findings differ based on the type and setting of study. It appears some older adults may be at risk of cognitive impairments attributable to OSA; however, the risk of bias renders the evidence inconclusive. High quality research is warranted in clinically diagnosed OSA patients as well as those already experiencing neuropsychological impairment and who may be regarded at higher risk of further cognitive decline.     

Black Males Living in an Antithetical Police Culture: Keys for Their Survival

Police killings of unarmed Black males is an all too often occurrence. Just how many have succumbed in this manner is unknown due to a lack of a comprehensive reporting method. However, an undeniable fact and reality is that the Black community, and society as a whole, suffers as a result of the loss of these individuals. The authors of this article suggest that police shootings of unarmed Black males may never cease. The authors propose simple but thoughtful ways in which Black males should be educated by the Black community (family, church, and other institutions) regarding general survival skills and more specifically survival skills in regards to police encounters. Implications for further research are also presented.     

SwarmSight: Measuring the temporal progression of animal group activity levels from natural-scene and laboratory videos

We describe SwarmSight (available at https://github.com/justasb/SwarmSight), a novel, open-source, Microsoft Windows software tool for quantitative assessment of the temporal progression of animal group activity levels from recorded videos. The tool utilizes a background subtraction machine vision algorithm and provides an activity metric that can be used to quantitatively assess and compare animal group behavior. Here we demonstrate the tool’s utility by analyzing defensive bee behavior as modulated by alarm pheromones, wild-bird feeding onset and interruption, and cockroach nest-finding activity. Although more sophisticated, commercial software packages are available, SwarmSight provides a low-cost, open-source, and easy-to-use alternative that is suitable for a wide range of users, including minimally trained research technicians and behavioral science undergraduate students in classroom laboratory settings.     

The Relationship Between Perceptions of Neighborhood Characteristics and Substance Use Among Urban African American Adolescents

Although the neighborhood microsystem is recognized as an important domain for adolescent development, relative to the family and peer contexts, neighborhood factors have been understudied in relation to adolescent substance abuse. In addition, recent research suggests that risk factors for adolescent substance use may differ for African Americans when compared to Caucasian youth. This study investigated the association between perceived neighborhood disorganization and later substance use, as well as possible mediators of that association, among a community sample of urban African American adolescents. Perceptions of neighborhood disorganization (i.e., violence/safety and drug activity) in grade 7 were associated with increased tobacco, alcohol, and marijuana use in grade 9. For females, this association was mediated by attitudes about drug use and perceptions of drug harmfulness. Findings highlight the importance of neighborhood contextual variables for African American substance use. Implications and directions for future research are presented.     

Selection from perceptual and conceptual representations

The lateral prefrontal cortex has been implicated in a wide variety of functions that guide our behavior, and one such candidate function is selection. Selection mechanisms have been described in several domains spanning different stages of processing, from visual attention to response execution. Here, we consider two such mechanisms: selecting relevant information from the perceptual world (e.g., visual selective attention) and selecting relevant information from conceptual representations (e.g., selecting a specific attribute about an object from long-term memory). Although the mechanisms involved in visual selective attention have been well characterized, much less is known about the latter case of selection. In this article, we review the relevant literature from the attention domain as a springboard to understanding the mechanisms involved in conceptual selection.     

Dissociating semantic and phonological maintenance using fMRI

Functional magnetic resonance imaging (fMRI) distinguished regions of neural activity associated with active maintenance of semantic and phonological information. Subjects saw a single word for 2 sec, and following a 10-sec delay, made a judgment about that word. In the semantic task, subjects focused on the meaning of the word and decided whether a second word was synonymous with it. In the phonological task, subjects repeated the word silently and decided whether it shared a vowel sound with a nonsense word. Analyses allowed for isolation of neural activity during the maintenance delay. Semantic maintenance elicited greater activity in bilateral inferior frontal gyrus and left middle temporal gyrus regions of interest (ROI). In contrast, there was greater activity for phonological maintenance in the left superior parietal ROI. These results show a frontal-temporal network involved in actively maintaining the meanings of words, and they indicate that semantic and phonological maintenance processes are dissociable within working memory.
