Speaking a tone language enhances musical pitch perception in 3–5‐year‐olds

Young children learn multiple cognitive skills concurrently (e.g., language and music). Evidence is limited as to whether and how learning in one domain affects that in another during early development. Here we assessed whether exposure to a tone language benefits musical pitch processing among 3–5‐year‐old children. More specifically, we compared the pitch perception of Chinese children who spoke a tone language (i.e., Mandarin) with English‐speaking American children. We found that Mandarin‐speaking children were more advanced at pitch processing than English‐speaking children but both groups performed similarly on a control music task (timbre discrimination). The findings support the Pitch Generalization Hypothesis that tone languages drive attention to pitch in nonlinguistic contexts, and suggest that language learning benefits aspects of music perception in early development.

Early development of letter specialization in left fusiform is associated with better word reading and smaller fusiform face area

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception.     

Beyond the broom cupboard: teaching assistants’ reflections upon the wider impact of their specialist dyslexia training

Whilst the government-commissioned Rose Report (2009) on provision and support for dyslexic learners in England called for the deployment of more specialist dyslexia teachers in mainstream schools, the reality seems to be that the job of teaching literacy to children with dyslexia is falling to teaching assistants (TAs). As a result, specialist training courses for TAs have been developed in England. Using the Coldwell and Simkins Training Impact Framework, the present study examines TAs participants’ perceptions of the impact of two such local authority-based training programmes, not just in terms of the impact upon their individual practice, but also in terms of their perceptions of the wider impact of their status as a trained ‘expert’ upon their schools’ policies, culture and practice. ‘Enabling’ and ‘blocking’ factors influencing this wider impact are identified, and implications for the deployment of specialist TAs and the design of their training courses are discussed.     

Beyond Consent: Building Trusting Relationships With Diverse Populations in Precision Medicine Research

With the growth of precision medicine research on health data and biospecimens, research institutions will need to build and maintain long-term, trusting relationships with patient-participants. While trust is important for all research relationships, the longitudinal nature of precision medicine research raises particular challenges for facilitating trust when the specifics of future studies are unknown. Based on focus groups with racially and ethnically diverse patients, we describe several factors that influence patient trust and potential institutional approaches to building trustworthiness. Drawing on these findings, we suggest several considerations for research institutions seeking to cultivate long-term, trusting relationships with patients: (1) Address the role of history and experience on trust, (2) engage concerns about potential group harm, (3) address cultural values and communication barriers, and (4) integrate patient values and expectations into oversight and governance structures.     

Prepubertal social gender transitions: What we know; what we can learn—A view from a gender affirmative lens

ABSTRACT

?Background: This article provides a review and commentary on social transition of gender-expansive prepubertal youth, analyzing risks, and benefits based on a synthesis of research and clinical observation, highlighting controversies, and setting forth recommendations, including the importance of continued clinical research.

Methods: This article involved: (1) a review and critique of the WPATH Standards of Care 7th edition guidelines on social transition; (2) a review and synthesis of empirical research on social transition in prepubertal children; (3) a discussion of clinical practice observations; (4) a discussion of continuing controversies and complexities involving early social transition; (5) a discussion of risks and benefits of social transition; and (6) conclusions and recommendations based upon the above.

Results: Results suggest that at this point research is limited and that some of the earliest research on young gender-expansive youth is methodologically questionable and has not been replicated. Newer research suggests that socially transitioned prepubertal children are often well adjusted, a finding consistent with clinical practice observations. Analysis of both emerging research and clinical reports reveal evidence of a stable transgender identity surfacing in early childhood.

Discussion: The authors make recommendations to support social transitions in prepubertal gender-expansive children, when appropriate, as a facilitator of gender health, defined as a child's opportunity to live in the gender that feels most authentic, acknowledging that there are limitations to our knowledge, and ongoing research is essential.     

Online webcam-based eye tracking in cognitive science: A first look

Online experimentation is emerging in many areas of cognitive psychology as a viable alternative or supplement to classical in-lab experimentation. While performance- and reaction-time-based paradigms are covered in recent studies, one instrument of cognitive psychology has not received much attention up to now: eye tracking. In this study, we used JavaScript-based eye tracking algorithms recently made available by Papoutsaki et al. (International Joint Conference on Artificial Intelligence, 2016) together with consumer-grade webcams to investigate the potential of online eye tracking to benefit from the common advantages of online data conduction. We compared three in-lab conducted tasks (fixation, pursuit, and free viewing) with online-acquired data to analyze the spatial precision in the first two, and replicability of well-known gazing patterns in the third task. Our results indicate that in-lab data exhibit an offset of about 172 px (15% of screen size, 3.94° visual angle) in the fixation task, while online data is slightly less accurate (18% of screen size, 207 px), and shows higher variance. The same results were found for the pursuit task with a constant offset during the stimulus movement (211 px in-lab, 216 px online). In the free-viewing task, we were able to replicate the high attention attribution to eyes (28.25%) compared to other key regions like the nose (9.71%) and mouth (4.00%). Overall, we found web technology-based eye tracking to be suitable for all three tasks and are confident that the required hard- and software will be improved continuously for even more sophisticated experimental paradigms in all of cognitive psychology.
