Purpose: A range of nonword repetition (NWR) tasks are used in research and clinical applications, but compliance rates among young children remain low. Live presentation is usually used to improve compliance rates, but this lacks the consistency of recorded stimuli. In this study, the authors examined whether a novel delivery of NWR stimuli based…

Purpose: To determine how increased vocal loudness and reduced speech rate affect listeners' cognitive-perceptual processing of hypokinetic dysarthric speech associated with Parkinson's disease. Method: Fifty-one healthy listener participants completed a speech perception experiment. Listeners repeated phrases produced by 5 individuals…

Purpose: The authors examined sentence imitation as a potential clinical marker of specific language impairment (SLI) in Czech and its use to identify grammatical markers of SLI. Method: Children with SLI and the age-and language-matched control groups (total N = 57) were presented with a sentence imitation task, a receptive vocabulary task, and…

The informativity of a computational model of language acquisition is directly related to how closely it approximates the actual acquisition task, sometimes referred to as the model's "cognitive plausibility." We suggest that though every computational model necessarily idealizes the modeled task, an informative language acquisition…

This study explored the relationship between accuracy of and confidence in performance of 114 prospective primary school teachers in answering diagnostic questions on potential difference in parallel electric circuits. The participants were required to indicate their confidence in their answers for each question. Bias and calibration indices were…

The present experimental study explores whether teachers are "clever" thinkers when assessing students' credibility, i.e., saving cognitive resources when possible and making accurate judgments. Participants were asked to decide whether student statements about using unfair means during a test were true or deceptive. First, participants'…

Homework is a commonly used and occasionally controversial teaching practice in our public schools (Center for Public Education, 2007). Meta-analyses indicate that homework has positive effects on student learning that are moderated by age, subject area, and student characteristics (Hattie in Visible learning, Routledge, New York, 2009).…

The purpose of this study was to investigate the effect of singing video games on the pitch-matching skills of undergraduate students. Popular games like "Rock Band" and "Karaoke Revolutions" rate players' singing based on the correctness of the frequency of their sung response. Players are motivated to improve their…

Video continues to be used in many basic communication courses as a way for students to self-evaluate speechmaking. In this study, students (N = 71) presented speeches, viewed the video recordings, and produced self-generated feedback. Comparing student's self-estimated grades from the self-evaluation against earned grades resulted in composite…

The current study investigated whether parents are accurate judges of their own children's lie-telling behavior. Participants included 250 mother-child dyads. Children were between three and 11 years of age. A temptation resistance paradigm was used to elicit a minor transgressive behavior from the children involving peeking at a forbidden toy and…

In item response theory test scaling/equating with the three-parameter model, the scaling coefficients A and B have no impact on the c-parameter estimates of the test items since the cparameter estimates are not adjusted in the scaling/equating procedure. The main research question in this study concerned how serious the consequences would be if…

A major debate in the mental-rotation literature concerns the question of whether objects are represented holistically during rotation. Effects of object complexity on rotational speed are considered strong evidence against such holistic representations. In Experiment 1, such an effect of object complexity was markedly present. A closer look on…

Purpose: The purpose of this study was to develop a computerized adaptive test (CAT) version of the Philadelphia Naming Test (PNT; Roach, Schwartz, Martin, Grewal, & Brecher, 1996), to reduce test length while maximizing measurement precision. This article is a direct extension of a companion article (Fergadiotis, Kellough, & Hula, 2015),…

The most widely cited statistics on postsecondary students with disabilities in the United States are based on the Department of Education's quadrennial National Postsecondary Student Aid Study (NPSAS). However, these statistics are called into question by their substantial variability across NPSAS administrations and by results of the second…

The gender and number of a direct object clitic pronoun are based on the gender and number of the noun to which it refers. Grammatical gender is an intrinsic property of the lexical item that is independent from the natural sex of referents, whereas number is a non-intrinsic feature of nouns based on the conceptual level of quantity. The aim of…
