Toward a Bahá'í Concept of Mental Health: Implications for Clinical Practice

The author highlights the emerging interest in understanding religious beliefs as a resource for more fully conceptualizing clients' psychological functioning. Although various authors have explored religious theories of mental health in an effort to increase understanding of clients' problems, there is a dearth of information on the Bahá'í client and how this particular religion conceives of mental health. The purpose of this article is to create an initial formulation for a Bahá'í concept of mental health and to discuss its clinical implications to aid in counseling Bahá'í clients.     

Surface-illuminant ambiguity and color constancy: effects of scene complexity and depth cues

Two experiments were conducted to study how scene complexity and cues to depth affect human color constancy. Specifically, two levels of scene complexity were compared. The low-complexity scene contained two walls with the same surface reflectance and a test patch which provided no information about the illuminant. In addition to the surfaces visible in the low-complexity scene, the high-complexity scene contained two rectangular solid objects and 24 paper samples with diverse surface reflectances. Observers viewed illuminated objects in an experimental chamber and adjusted the test patch until it appeared achromatic. Achromatic settings made tinder two different illuminants were used to compute an index that quantified the degree of constancy. Two experiments were conducted: one in which observers viewed the stimuli directly, and one in which they viewed the scenes through an optical system that reduced cues to depth. In each experiment, constancy was assessed for two conditions. In the valid-cue condition, many cues provided valid information about the illuminant change. In the invalid-cue condition, some image cues provided invalid information. Four broad conclusions are drawn from the data: (a) constancy is generally better in the valid-cue condition than in the invalid-cue condition: (b) for the stimulus configuration used, increasing image complexity has little effect in the valid-cue condition but leads to increased constancy in the invalid-cue condition; (c) for the stimulus configuration used, reducing cues to depth has little effect for either constancy condition: and (d) there is moderate individual variation in the degree of constancy exhibited, particularly in the degree to which the complexity manipulation affects performance.     

Reasoning About Race and Pedagogy in Two Preservice Science Teachers: A Critical Race Theory Analysis

This study describes the experiences of two preservice science teachers as they progress through their respective teacher education programs and uses critical race theory to examine the manner in which conceptions about race and its pedagogical implications change over time. Using a longitudinal case study method, participants' conceptual ecologies of race and pedagogy are mapped both before and after student teaching, and each case is analyzed for evidence of conceptual change in these areas. Findings show that conceptions about race and the pedagogical implications of race changed in ways that likely would have gone undetected in earlier studies because they did not result in wholesale changes in beliefs or teaching practice. This study suggests that the difficulty of fostering an understanding of structural racism and difference may often be underestimated, as revising one's model about race is mitigated strongly by learners' existing conceptual ecologies.     

Impression‐formation advantage in memory for faces: When eyewitnesses are interested in targets' likeability,rather than their identity

The advantage in person memory of impression formation over memory task instructions is shown to extend to the eyewitness identification paradigm. Instructions to form an impression of target persons led to more accurate identifications in subsequent photo line‐ups than explicit instructions to memorize the targets (Experiment 1). Prior knowledge that a crime was going on did not affect performance. Two confounded components of the successful instruction condition were decomposed in Experiment 2, showing that the enhanced performance is due to the impression task proper, rather than the absence of explicit memory instructions. Analyses of hits and false alarms revealed that the positive influence of impression formation on discrimination performance was due to a genuine enhancement in discrimination ability rather than merely a shift toward a stricter response criterion. Experiment 3 provided some evidence to suggest that eyewitness performance can even be influenced by recontextualization efforts and impression judgments at the time of retrieval.

Statistical decision theory and evolution

Two recent articles by Geisler and Diehl use Bayesian statistical decision theory to model the co-evolution of predator and prey in a simple, game-like environment. The prey is characterized by its coloration. The predator is characterized by the chromatic sensitivity of its visual system and its willingness to attack. The authors demonstrate how the coloration of prey and the perceptual system of the predator co-evolve, converging to a Nash equilibrium for both species.     

Genetic Counselors’ Experience with and Opinions on the Management of Newborn Screening Incidental Carrier Findings

Newborn screening (NBS) is a public health program whose aim is to identify infants who will be clinically affected with a serious metabolic, genetic, or endocrine disorder; however, the technology utilized by many NBS programs also detects infants who are heterozygous carriers for autosomal recessive conditions. Discussion surrounding disclosure of these incidental carrier findings remains controversial. The purpose of this study was to assess genetic counselors’ attitudes about disclosure of carrier status results generated by NBS and to gather data on their experiences with incidental carrier findings. An electronic survey was distributed to genetic counselors of all specialties via the NSGC listserv, and a total of 235 survey responses were analyzed. Quantitative data were analyzed using IBM SPSS v24, and qualitative data were manually analyzed for thematic analysis. Results show that the counselor participants were overall in favor of routine disclosure. Those with experience in NBS were much more likely to strongly agree with one or more reasons for disclosure (p?<?0.001), whereas those with five or fewer years of experience were more likely to strongly agree with one or more reasons for non-disclosure (p?=?0.031). Qualitative analysis identified key motivating factors for disclosure, including helping parents to understand a positive screen, parents may otherwise be unaware of reproductive risk and they may not otherwise have access to this information, and, while genetic testing is inherently a complex and ambiguous process, this does not justify non-disclosure. The main motivating factor for non-disclosure was the need for better counseling and informed consent. The data suggest that implementation of an “opt-in/out” policy for parents to decide whether or not to receive incidental findings would be beneficial. The results of this study support the continued disclosure of incidental carrier findings; however, additional research is necessary to further determine and implement the most effective disclosure practices.     

Challenging the reliability and validity of cognitive measures: The case of the numerical distance effect

The numerical distance effect (NDE) is one of the most robust effects in the study of numerical cognition. However, the validity and reliability of distance effects across different formats and paradigms has not been assessed. Establishing whether the distance effect is both reliable and valid has important implications for the use of this paradigm to index the processing and representation of numerical magnitude in both behavioral and neuroimaging studies. In light of this, we examine the reliability and validity of frequently employed variants (and one new variant) of the numerical comparison task: two symbolic comparison variants and two nonsymbolic comparison variants. The results of two experiments demonstrate that measures of the NDE that use nonsymbolic stimuli are far more reliable than measures of the NDE that use symbolic stimuli. With respect to correlations between measures, we find evidence that the NDE that arises using symbolic stimuli is uncorrelated with the NDE that is elicited by using nonsymbolic stimuli. Results are discussed with respect to their implications for the use of the NDE as a metric of numerical processing and representation in research with both children and adults.     

More Similar than Different: Millennials in the U. S. Building Trades

Purpose  

The objective of this study is to investigate the extent to which generational differences exist among skilled workers within a single construction trade. Although Millennials have been the focus of attention in media reports and popular management literature, little attention has been paid to empirical examinations of skilled trade workers.     

Humans rapidly estimate expected gain in movement planning

We studied human movement planning in tasks in which subjects selected one of two goals that differed in expected gain. Each goal configuration consisted of a target circle and a partially overlapping penalty circle. Rapid hits into the target region led to a monetary bonus; accidental hits into the penalty region incurred a penalty. The outcomes assigned to target and penalty regions and the spatial arrangement of those regions were varied. Subjects preferred configurations with higher expected gain whether selection involved a rapid pointing movement or a choice by key press. Movements executed to select one of two goal configurations exhibited the same movement dynamics as pointing movements directed at a single configuration, and were executed with the same high efficiency. Our results suggest that humans choose near-optimal strategies when planning their movement, and can base their selection of strategy on a rapid judgment about the expected gain associated with possible movement goals.
