Purpose: This study evaluates the effects of a novel speech therapy program that uses a verbal cue and gamified augmented visual feedback regarding tongue movements to address articulatory hypokinesia during speech in individuals with Parkinson's disease (PD). Method: Five participants with PD participated in an ABA single-subject design study.…

This case was written to encourage educators to reflect on what it means to provide high-quality instructional supervision in an era of accountability when the American public education system is heavily influenced by reform efforts that affect how students learn and how teachers are supported as instructors, and pressures school systems face to…

Diffusion-based item response theory models for responses and response times in tests have attracted increased attention recently in psychometrics. Analyzing response time data, however, is delicate as response times are often contaminated by unusual observations. This can have serious effects on the validity of statistical inference. In this…

We observed three children with autism spectrum disorder during structured play dates in which play partners displayed interest or disinterest in the toys with which they were playing. We then taught subjects to identify play partners' preferences and to make appropriate toy offers using a multiple-exemplar training package consisting of rules,…

The resurgence of destructive behavior can occur during functional communication training (FCT) if the alternative response contacts a challenge (e.g., extinction). Behavioral momentum theory (BMT) suggests that refinements to FCT could mitigate resurgence of destructive behavior during periods of extinction. Following a functional analysis and…

This article reviews and compares recently proposed factor analytic and item response theory approaches to the study of invariance across groups. Two methods are described and contrasted. The alignment method considers the groups as a fixed mode of variation, while the random-intercept, random-loading two-level method considers the groups as a…

Self-assessment is an important tool enabling learners at the level of higher education to control and construct their learning processes. To allow for further study, we modified a web-based self-assessment system to provide individuals with the opportunity to test and retest their own learning and receive feedback. This study included 59…

As Facebook enables adolescents to present themselves positively by means of their Facebook profile and to gain positive feedback for doing so, the aim of the current study is to investigate which kinds of adolescents' positive self-presentation in profile pictures and status updates are associated with positive feedback in terms of Likes from the…

Conferences provide teachers a valuable context for giving both positive and constructive feedback that is tailored to individual students. Students who struggle with writing, however, are less apt to receive positive feedback on the craft of their writing, which is an important part of literacy development in the elementary and middle grades.…

This case study explored the impact a quality assurance course review had on instructors at University of Wisconsin--La Crosse (UWL). This in-house created rubric is used to conduct formal course reviews of online classes developed by instructors at this medium-sized Midwestern public university. Also included in this case study, are results from…

When testing a statistical mediation model, it is assumed that factorial measurement invariance holds for the mediating construct across levels of the independent variable X. The consequences of failing to address the violations of measurement invariance in mediation models are largely unknown. The purpose of the present study was to…

Across three studies, we examined 4- to 7-year-olds' predictions of goal-directed behaviors when goals conflict with preferences. In Study 1, when presented with stories in which a character had to act against basic preferences to achieve an interpersonal goal (e.g., playing with a partner), 6- and 7-year-olds were more likely than 4- and…

Diagnostic classification models (DCMs, also known as cognitive diagnosis models) hold the promise of providing detailed classroom information about the skills a student has or has not mastered. Specifically, DCMs are special cases of constrained latent class models where classes are defined based on mastery/nonmastery of a set of attributes (or…

Interactional competence has been variously defined as turn-taking ability, paralinguistic features of communication such as eye contact, gesture, and gesticulation, and listener responses. In existing assessment systems such as the oral proficiency interview (OPI), interactional competence is only rarely explicitly factored into the holistic…

Emotional arousal enhances memory encoding and consolidation leading to better immediate and delayed memory. Although the central noradrenergic system and the amygdala play critical roles in both effects of emotional arousal, we have recently shown that these effects are at least partly independent of each other, suggesting distinct underlying…
