Background: Stuttering is a neurodevelopmental disorder affecting speech flow, often hampering social interaction and academic performance in childhood. However, data on the prevalence and impact of stuttering amongst school-aged children remains limited in Ghana. Objective: This study aimed to determine the prevalence, gender distribution,…

Objective: To compare neurofunctional responses in emotional and attentional networks of psychostimulant-free ADHD youth with and without familial risk for bipolar I disorder (BD). Methods: ADHD youth with (high-risk, HR, n = 48) and without (low-risk, LR, n = 50) a first-degree relative with BD and healthy controls (n = 46) underwent functional…

This article is a critical review of a book by Sir William Wilde (better known as the father of Oscar Wilde) entitled "On the Physical, Moral, and Social Condition of the Deaf and Dumb" (1854). This book, which is based on the demographic and medical information that he collected from "deaf and dumb" people in the early 1850s,…

Problem Addressed: To better understand the factors associated with family cancer history (FCH) information and cancer information seeking, we model the process an individual undergoes when assessing whether to gather FCH and seek cancer information and compare models by sociodemographics and family history of cancer. We used cross-sectional data…

Objective: To use a family genetic study to evaluate familial risk of obsessive compulsive disorder (OCD) and common comorbid illnesses in first-degree relatives of pediatric-onset probands with primary OCD. Method: One hundred and thirty youth with OCD and their 133 siblings and 241 parents and 49 pediatric controls were directly evaluated along…

The aim of the study was to perform family-based association analysis of "PRKCB1," "CBLN1" and "KCNMB4" gene polymorphisms and autism disorder. We comprised 206 Caucasian children with autistic spectrum disorder (ASD) and their biological parents. In transmission/disequilibrium test we observed that T-allele of the…

Every baby brings its own temperament with it into the world. Although it is widely accepted by scientists that genetic factors are effective in the formation of temperament, this study aims to examine the possible effects of the pregnancy process on the temperament characteristics of children in line with the experiences of mothers and the role…

Recent findings in behavioral genetics and technological advances have the potential to alter education administration in ways that were inconceivable just a decade ago. Specifically, new understandings about the heritability of educational outcomes and the ability to calculate polygenic scores that predict likely student outcomes could change how…

The broad autism phenotype (BAP) is a set of characteristics often observed in typically developing people with a genetic load for autism, such as parents of autistic children. The Broad Autism Phenotypic Questionnaire (BAPQ) is a 36-item questionnaire developed to identify the BAP in first-degree relatives of autistic people. We translated the…

There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting…

Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on…

This study addresses eugenics and their relationship with the discourse on sex and gender in the field of Physical Education in Uruguay, specifically in Physical Education teacher training (1948-1970). The sources used include the main works and articles of national and regional leading authors in the field, the syllabi of several subjects of the…

The paper presents an experimental study that examines the conditions required for news about behavioral genetics to activate genetic essentialism beliefs. Nine hundred sixty-five adults living in the USA were randomly assigned to read either a control news article or one of the three versions of a news story about behavioral genetics. The…

Generic descriptions (e.g., 'girls are emotional') are argued to play a major role in the development of essentialist reasoning about social categories. Although generics are prevalent across languages, studies exploring if and how generic language leads to essentialism have almost exclusively been conducted in English-speaking communities and…

Genetics is a core topic in the biology curriculum of many countries. Learning genetics is difficult for multiple reasons, including the need to reason about complex mechanisms--and to link mechanisms--that occur at different time and space scales. Previous research in genetics education explores students' understandings of inheritance patterns or…
