Growth models (GM) of the mixed-effects and latent curve varieties have become popular methodological tools in lifespan research. One of the major advantages of GM is their flexibility in studying individual differences in change. We scrutinized the change functions of GM used in five years of publications on cognitive aging. Of the 162…

Factorial surveys are widely used in the social sciences to measure respondents' attitudes, beliefs, or behavioral intentions. In such surveys, respondents evaluate short descriptions of hypothetical situations, persons, or objects that vary across several dimensions. An important prerequisite of the method's validity is that respondents are able…

Purpose: Speech perception is facilitated by listeners' ability to dynamically modify the mapping to speech sounds given systematic variation in speech input. For example, the degree to which listeners show categorical perception of speech input changes as a function of distributional variability in the input, with perception becoming less…

This study examined differences in generalized and social anxiety symptoms across two age groups of children with autism spectrum disorder (ASD) while accounting for overall anxiety level, gender, and intellectual functioning. Older children (12-18 years) expressed more overall and social anxiety symptoms than younger children (6-11 years), and…

This study aimed to draw a cross-task comparison on visuospatial processing in autism spectrum disorder without intellectual disability. Participants with autism spectrum disorder were matched with typically developing individuals on general intelligence and perceptual reasoning index. The two groups were subsequently compared on visuospatial…

Spatial reasoning skills are necessary to perform activities at school, at work and in everyday life, in general. Different studies indicate the importance of its development at an early age, since it allows the reading of a three-dimensional world and its interpretation in two-dimensional representations. Our research focuses on the design of…

In this chapter we use the posthumanist perspective introduced in Chapter 2 to work with a range of 'data events' from the "Beyond Words" study involving post-verbal people with dementia and their close networks. We discuss and critique the primacy of 'voice' in lifelong learning, where it has been highly privileged. Instead, our…

Spatial thinking is important in predicting students' success in STEM fields. However, there is limited knowledge about "how" students learn spatial skills during classroom instruction by using strategies that support their cognition. This dissertation addresses this gap as I explored "spatial sensemaking practices" that…

The quality of undergraduate student writing is cause for concern among academics and industry professionals alike. Because writing apprehension is thought to be a contributing factor in the current deficit of undergraduate writing proficiency, the Writing Apprehension Test (WAT) was administered to parks, recreation, and tourism students to…

School engagement in adolescence is often associated with better academic performance at school, but what are the longitudinal associations between school engagement and adult educational and employment status? The current study explored these longitudinal associations using data spanning 40-years of life, from the 1970 British Cohort Study.…

The Early Start Denver Model is an evidence-based, comprehensive naturalistic developmental behavioral intervention for young and very young children with autism spectrum disorder. This interdisciplinary model is suitable for the Taiwanese public health system. In this study, we evaluated the effectiveness of an Early Start Denver Model program…

Background: The reciprocal internal/external frame of reference (RI/E) combines two models of academic self-concept formation, namely the reciprocal effects model (REM) and the internal/external frame of reference (I/E) model. The REM assumes reciprocal relations between achievement and academic self-concept. The I/E model assumes contrast effects…

The present paper introduces a general multidimensional model to measure individual differences in learning within a single administration of a test. Learning is assumed to result from practicing the operations involved in solving the items. The model accounts for the possibility that the ability to learn may manifest differently for correct and…

Ability grouping of students into separate classes within a school can be called 'between-class ability grouping'. This practice has persisted in Australia despite evidence that it is socially inequitable and does not improve academic outcomes. A systematic review of peer-reviewed literature about between-class ability grouping in Australia from…

This article is intended to contribute to greater knowledge regarding the importance of flow and the time used to perform an activity, with a focus on students' mathematical experiences of 3D bodies. Thirty-one 9th-grade students took part in the study. Flow and variation theory was used in the analysis of lesson observations, submission tasks,…
