The mathematical abilities of children with cochlear implants

Research has shown that cochlear implants give rise to improvements in speech recognition and production in children with profound hearing loss but very few studies have explored mathematical abilities in these children. The current study compared the mathematical abilities of 24 children with cochlear implants (mean age 10 years 1 month) to a control group of 22 hearing children (mean age 9 years 8 months). The math questions were categorized into questions that tapped into arithmetic or geometrical reasoning. It was predicted that the cochlear implant group would perform below the hearing group on the arithmetic questions but not the geometrical reasoning questions. Unexpectedly, the results showed that the cochlear implant group performed significantly below the hearing group on both types of math questions, but that this difference was mediated by language skill as assessed by vocabulary knowledge. The clinical implications of these results and possible future research results are considered.     

Digital Animation as a Method to Disseminate Research Findings to the Community Using a Community-Based Participatory Approach

Community-based participatory research (CBPR) has garnered increasing interest over the previous two decades as researchers have tackled increasingly complex health problems. In academia, professional presentations and articles are major ways that research is disseminated. However, dissemination of research findings to the people and communities who participated in the research is many times forgotten. In addition, little scholarly literature is focused on creative dissemination of research findings to the community using CBPR methods. We seek to fill this gap in the literature by providing an exemplar of research dissemination and partnership strategies that were used to complete this project. In this paper, we present a novel approach to the dissemination of research findings to our targeted communities through digital animation. We also provide the foundational thinking and specific steps that were taken to select this specific dissemination product development and distribution strategy.     

Recognition of Affective Speech Prosody and Facial Affect in Deaf Children with Unilateral Right Cochlear Implants

Cochlear implant (CI) devices provide the opportunity for children who are deaf to perceive sound by electrical stimulation of the auditory nerve, with the goal of optimizing oral communication. One part of oral communication concerns meaning, while another part concerns emotion: affective speech prosody, in the auditory domain, and facial affect, in the visual domain. It is not known whether childhood CI users can identify emotion in speech and faces, so we investigated speech prosody and facial affect in children who had been deaf from infancy and experienced CI users. METHOD: Study participants were 18 CI users (ages 7–13 years) who received right unilateral CIs and 18 age- and gender-matched controls. Emotion recognition in speech prosody and faces was measured by the Diagnostic Analysis of Nonverbal Accuracy. RESULTS: Compared to controls, children with right CIs could identify facial affect but not affective speech prosody. Age at test and time since CI activation were uncorrelated with overall outcome measures. CONCLUSION: Children with right CIs recognize emotion in faces but have limited perception of affective speech prosody.     

Burnout and its relations with basic psychological needs and motivation among athletes: A systematic review and meta-analysis

ObjectivesThe present study is a review on studies about the relationships between the three basic psychological needs/motivational regulations (i.e., amotivation, controlled regulation, extrinsic autonomous regulation, and intrinsic motivation) and burnout.DesignA systematic review and meta-analysis.MethodStudies were identified through five electronic databases and manual search using combinations of three groups of keywords. Three inclusion criteria were then used to screen the searched articles.ResultsEighteen studies met the inclusion criteria and these studies varied considerably in terms of their study characteristics (e.g., characteristics of participants, study designs, and outcome measures). The results also showed that the three basic psychological needs, intrinsic motivation, extrinsic autonomous regulation, and amotivation had small to large effects on predicting global burnout and its three dimensions. However, controlled regulation showed no or weak correlations with the burnout subscales.ConclusionsSelf-determination theory was generally supported in explaining athlete burnout.     

BODY WORLDS: Choosing to Be Immortalized as an Educational Specimen

Research ethics education in the biosciences has not historically been a priority for research universities despite the fact that funding agencies, government regulators, and the parties involved in the research enterprise agree that it ought to be. The confluence of a number of factors, including scrutiny and regulation due to increased public awareness of the impact of basic research on society, increased public and private funding, increased diversity and collaboration among researchers, the impressive success and speed of research advances, and high-profile cases of misconduct, have made it necessary to reexamine how the bioscience research community at all levels provides ethics education to its own. We discuss the need to and reasons for making ethics integral to the education of bioscientists, approaches to achieving this goal, challenges this goal presents, and responses to those challenges.     

Community Psychology and Quality of Life in Tanzania

The purpose of this study was to explore the status of community psychology and its contribution to the quality of life in Tanzania. The study was based on both literature review and interviews. First, social responses to problems such as malaria, food insecurity, domestic violence, environmental changes, and HIV/AIDS are discussed. This is followed by a report on the results of five face-to-face interviews of individuals working in the fields of psychology, sociology, social work, counseling and public health. The participants were predominantly from the Capital City of Dar es Salam and one hailed from the city of Mbeya, 850 km from Dar es Salaam. The interviews were exclusively conducted in English as all participants were fluent in English, though it was their second language. On the basis of the literature review and the interviews, it was concluded that although community psychology has made some progress in contributing to quality of life in Tanzania, it is a field of great potential which must be further explored for the benefit of Tanzanians.     

单一被试实验与元分析技术

Noise,Economy, and the Emergence of Information Structure in a Laboratory Language

The acceptability of sentences in natural language is constrained not only grammaticality, but also by the relationship between what is being conveyed and such factors as context and the beliefs of interlocutors. In many languages the critical element in a sentence (its focus) must be given grammatical prominence. There are different accounts of the nature of focus marking. Some researchers treat it as the grammatical realization of a potentially arbitrary feature of universal grammar and do not provide an explicit account of its origins; others have argued, however, that focus marking is a (grammaticalized) functional solution to the problem of efficiently transmitting information via a noisy channel. By adding redundancy to highlight critical elements in particular, focus protects key parts of the message from noise. If this information‐theoretic account is true, then we should expect focus‐like behavior to emerge even in non‐linguistic communication systems given sufficient noise and pressures for efficiency. We tested this in an experiment in which participants played a simple communication game in which they had to click cells on a grid to communicate one of two line figures drawn across the grid. We manipulated the noise, available time, and required effort, and measured patterns of redundancy. Because the lines in many cases overlapped, meaning that only some parts of each line could be used to distinguish it from the other, we were able to compare the extent to which effort was expended on adding redundancy to critical (non‐overlapping) and non‐critical (overlapping) parts of the message. The results supported the information‐theoretic account of focus and shed light on the emergence of information structure in language.     

Evidence for differentiation of right hemisphere visual-perceptual functions

Performance on tasks sensitive to right hemisphere dysfunction (facial discrimination and perceptual closure) are reported in eight patients with right hemisphere lesions. Patients demonstrated an apparent double dissociation of performance on the two measures. Site-by-task specificity for the closure task was strongly suggested. Implications for right hemisphere organization and underlying psychological processes are considered.     

Process, Content, and Feminist Reflexivity: One Researcher's Exploration

This article explores the unraveling of the relationship between research methodology, process, and content as revealed through my own feminist research project. I examine the evolution of my research process with one participant from a larger study, as I sought to better understand a story she told about racism. First, I address the theoretical underpinnings of feminist reflexivity and research, which challenge traditional paradigms. Next, I present the participant's (a white family day care provider's) story about racism in her practice which was revealed during an interview process. Subsequently, I present a second dialogue around the story in which we (researcher and participant) later engaged. In the process, I analyze my struggles, as a researcher trained in positivist methods, to engage in reflexive research methods. Finally, I evaluate the gains made for me as a researcher in the process and content of research conducted with a feminist reflexive frame and suggest their utility in deconstructing White racism.
