Purpose: Acoustic measurement of speech sounds requires first segmenting the speech signal into relevant units (words, phones, etc.). Manual segmentation is cumbersome and time consuming. Forced-alignment algorithms automate this process by aligning a transcript and a speech sample. We compared the phoneme-level alignment performance of five…

Several concerted movements toward mathematical modeling have been seen in the last decade, reflecting the growing global relationship between the role of mathematics in the context of modern science, technology and real life. The literature has mainly covered the theoretical basis of research questions in mathematical modeling and the use of…

Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two…

Age-related differences in explicit and implicit racial biases in Black Cameroonians (N = 187, 94 females) were investigated using a cross-sectional design. Participants ranged in age from 3 to 30 years, and were from middle-to-high income families in Yaoundé, Cameroon. Biases were assessed by comparing attitudes toward Blacks with those toward…

The objective of this study was to determine gastrointestinal transit time in first-year health science students with a laboratory practical exercise conducted in two cohorts (classes of 2018 and 2019) of first-year health sciences students at the Health Science Campus in Windhoek, Namibia. All first-year health science students undertaking the…

The study aimed to examine the relationship between the stress levels of parents with preschool children and the variables of the parents' gender, age, education level, perceived income level, number of children and age of the child. The study was carried out via relational scanning model. The participants of the study were selected using easy…

This study focused on the identification of the factors that affect study habits in higher education during the Covid-19 pandemic based on students' opinions. In the study designed according to the exploratory sequential design among mixed research methods, interviews were conducted with 94 second and third-year students who volunteered to…

Purpose: We extended our earlier study on normative growth curves for intelligibility development in typical children from 30 to 119 months of age. We also determined quantile-specific age of steepest growth and growth rates. A key goal was to establish age-specific benchmarks for single-word and multiword intelligibility. Method: This…

The article deals with the evaluation of university graduates' attitudes towards job characteristics based on their generation. Research shows that the attitudes of individuals in the labor market are currently changing. However, the question is to what extent this change is related to the entry of a new generation or to what extent generational…

Purpose: The primary aim of this study was to obtain high-quality acoustic normative data in natural field environments for female voices. A secondary aim was to examine acoustic measurement variability in field environments. Method: This study employed a within-subject repeated-measures experimental design that included 45 young female adults…

Developmental researchers commonly utilize multilevel models (MLMs) to describe and predict individual differences in change over time. In such growth model applications, researchers have been widely encouraged to supplement reporting of statistical significance with measures of effect size, such as R-squareds ("R[superscript 2]") that…

Interest in spatial ability has grown over the past few decades following the emergence of correlational evidence associating spatial aptitude with educational performance in the fields of science, technology, engineering, and mathematics. The research field at large and the anatomy education literature on this topic are mixed. In an attempt to…

The first goal of this study was to examine how individual differences in initial L2 proficiency help explain L2 grammar development in oral production during short-term immersion abroad. The second goal of the study was methodological, and evaluated challenges that can result from operationalizing learners' initial L2 proficiency as pretest…

Special education policy impacts education equity. More specifically, special education policy surrounding the identification of students with disabilities and the provision of instructional support services to students identified as having a disability has experienced critical public attention and landmark federal and state mandates for reform…

We tested whether changes in attribution processes could account for the developmental differences observed in how children's use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during…
