Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.     

Considered evaluation of clinical placements in a new medical school

This article suggests that quality assessment in the UK has been largely set apart from learning and teaching and reports on a pilot project at the Hull York Medical School which attempted to integrate students’ evaluation of their clinical placements into the curriculum. It outlines the operational demands of this integrated method and compares the student experience of different evaluation methods. It argues that, when properly prepared and considered, evaluation can help students to practise useful skills and suggests that integrating this type of evaluation into the curriculum could be a step towards encouraging academic staff to engage with quality processes.     

Developmental Differences in Relations Between Episodic Memory and Hippocampal Subregion Volume During Early Childhood

Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic memory and volume of subregions (head, body, and tail) of the hippocampus—a structure known to support episodic memory in school‐aged children and adults—during early childhood (n = 45). Results revealed significant positive relations between episodic memory and volume of the hippocampal head in both the left and right hemispheres for 6‐ but not 4‐year‐old children, suggesting brain–behavior relations vary across development. These findings add new information regarding neural mechanisms of change in memory development during early childhood and suggest that developmental differences in hippocampal subregions may contribute to age‐related differences in episodic memory ability.     

Attentional capture by spoken language: effects on netballers’ visual task performance

Abstract

In two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design.     

Effects of student-facilitated learning on instructional facilitators

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.     

Reporting Quality of Single-Case Research Published in Learning Disabilities Journals

Single-case research designs are useful for learning disability researchers interested in refining novel interventions (e.g., new mathematics intervention) before scaling, small n populations (e.g., students with comorbid learning and emotional and behavioral disabilities), and testing unique conditions (e.g., remote locales). Much attention has been devoted to developing research quality standards, which is essential for replication and implementation fidelity; however, little is known about the reporting quality of single-case design studies. To gain insight into the quality of learning disability single-case research design study reporting, we analyzed 72 articles published between 2010 and 2021 in six learning disability-focused journals using the Single-Case Reporting Guideline In BEhavioral interventions (SCRIBE) standards. Findings suggest that reporting quality has remained stagnant, and none of the studies reviewed met all of the reporting standards. Alignment with standards ranged from 33% to 77%. Implications for researchers and practitioners are discussed.     

Superior Detection of Faces in Male Infants at 2 Months

Females generally attend more to social information than males; however, little is known about the early development of these sex differences. With eye tracking, 2-month olds’ (N = 101; 44 females) social orienting to faces was measured within four-item image arrays. Infants were more likely to detect human faces compared to objects, suggesting a functional face detection system. Unexpectedly, males looked longer at human faces than females, and only males looked faster and longer at human faces compared to objects. Females, in contrast, looked less at human faces relative to animal faces and objects, appearing socially disinterested. Notably, this is the first report of a male face detection advantage at any age. These findings suggest a unique stage in early infant social development.     

What does ‘inclusion’ mean for pupils on the autistic spectrum in mainstream secondary schools?

The last decade has seen a groundswell of developments in educational policy in the UK relating to inclusive education for students with special educational needs (SEN). However, whether government policy has been fully implemented in schools remains a concern. The experience of students with autistic spectrum disorders (ASDs) provides an excellent case in point. An increasing number of such students are now educated in mainstream schools, but the limited research in this area has indicated that their experience of school is often marked by bullying, social isolation and anxiety. In light of this, the aim of the current study was to examine the extent to which inclusive educational policy was actually reflected in the practices of four mainstream secondary schools. An exploratory case study approach was adopted, utilising interviews with pupils, teachers, other school staff (e.g., senior managers, learning support assistants) and parents, observations of lessons and other contexts (e.g., lunch time), and document analysis. Our findings highlighted a number of school practices which acted as facilitators or barriers to students’ learning and participation, some of which were generic to SEN provision, and some of which appeared to be specific to those on the autistic spectrum. A discussion of these is presented to enable further understanding of, and inform practice relating to, the inclusion process for students with ASDs.     

Teaching bovine abdominal anatomy: Use of a haptic simulator

Traditional methods of teaching anatomy to undergraduate medical and veterinary students are being challenged and need to adapt to modern concerns and requirements. There is a move away from the use of cadavers to new technologies as a way of complementing the traditional approaches and addressing resource and ethical problems. Haptic (touch) technology, which allows the student to feel a 3D computer‐generated virtual environment, provides a novel way to address some of these challenges. To evaluate the practicalities and usefulness of a haptic simulator, first year veterinary students at the Royal Veterinary College, University of London, were taught basic bovine abdominal anatomy using a rectal palpation simulator: “The Haptic Cow.” Over two days, 186 students were taught in small groups and 184 provided feedback via a questionnaire. The results were positive; the majority of students considered that the simulator had been useful for appreciating both the feel and location of key internal anatomical structures, had helped with their understanding of bovine abdominal anatomy and 3D visualization, and the tutorial had been enjoyable. The students were mostly in favor of the small group tutorial format, but some requested more time on the simulator. The findings indicate that the haptic simulator is an engaging way of teaching bovine abdominal anatomy to a large number of students in an efficient manner without using cadavers, thereby addressing some of the current challenges in anatomy teaching.
