Background: Mobility limitations are of particular interest in people with intellectual disabilities. The aim of this study was to present feasibility and mean values of gait parameters in people with intellectual disability and it was hypothesized that several trials would be necessary to gain stable values for this cohort. Material and Methods:…

Infants learning languages with long consonants, or geminates, have been found to "overselect" and "overproduce" these consonants in early words and also to commonly omit the word-initial consonant. A production study with thirty Italian children recorded at 1;3 and 1;9 strongly confirmed both of these tendencies. To test the…

This note is concerned with examining the relationship between within-group and between-group variances in two-level nested designs. A latent variable modeling approach is outlined that permits point and interval estimation of their ratio and allows their comparison in a multilevel study. The procedure can also be used to test various hypotheses…

Prosocial behavior is a highly heterogeneous construct, and young children use distinct prosocial actions in response to differing emotional needs of another person. This study examined whether toddlers' prosocial responses differed in response to two understudied emotional contexts--whether or not children caused a victim's distress and the…

In a time of abundant information, misinformation, and disinformation, information literacy--the ability to find, evaluate, use, and share information--is a key competency for people of all ages. Traditional models of information literacy depict a universal set of skills that can only be learned via instruction from an information professional and…

Psychologists and educators have long pointed to myriad benefits of self-directed learning. Yet evidence of its efficacy in real-world domains is mixed and it remains unclear how it is constrained by basic perceptual and cognitive processes. Previous work suggests that, in particular, self-directed learning is affected by the way that people…

National and state-based science and Science, Technology, Engineering, and Mathematics (STEM) initiatives expect educators to incorporate inquiry- and design-based practices into their STEM-centric lesson planning. While this is a new expectation and may be a challenge for all, it is an even more prohibitive barrier for elementary teachers who…

The null hypothesis test used in differential item functioning (DIF) detection tests for a subgroup difference in item-level performance--if the null hypothesis of "no DIF" is rejected, the item is flagged for DIF. Conversely, an item is kept in the test form if there is insufficient evidence of DIF. We present frequentist and empirical…

Information literacy skills are the ability that enables learners to successfully surf the internet in search of information to improve learning. The internet is a platform that consists of different resources where learners can search for and retrieve information. However, undergraduates do not possess the skills to surf the internet, find and…

Primary School Teachers in Fiji are employed and supervised by the Ministry of Education and are expected to teach all subjects prescribed by the Ministry with necessary teacher qualification. The objectives of the study is to examine the current status of MKT for Primary School Mathematics Teachers in Fiji schools in terms of its components;…

Five-month-old infants selectively attend to novel people who sing melodies originally learned from a parent, but not melodies learned from a musical toy or from an unfamiliar singing adult, suggesting that music conveys social information to infant listeners. Here, we test this interpretation further in older infants with a more direct measure of…

The formation of mate recognition memory in mice is associated with neural changes at the reciprocal dendrodendritic synapses between glutamatergic mitral cell (MC) projection neurons and GABAergic granule cell (GC) interneurons in the accessory olfactory bulb (AOB). Although noradrenaline (NA) plays a critical role in the formation of the memory,…

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design…

In the recent years in the End-User Development (EUD) research there is a shift from the study of tools that focus on desktop graphical applications, to the development of EUD for web environments. Human-Computer Interaction (HCI) research has shown significant gender differences while users interact with EUD systems. However, most of this…

Parallel analysis (PA) is a useful empirical tool for assessing the number of factors in exploratory factor analysis. On conceptual and empirical grounds, we argue for a revision to PA that makes it more consistent with hypothesis testing. Using Monte Carlo methods, we evaluated the relative accuracy of the revised PA (R-PA) and traditional PA…
