Background: Mortality studies can help reduce health inequalities by informing public policy through a better understanding of causes of death and comorbidities. Mortality studies often rely on Medical Certificates of Cause of Death (MCCD) for data. Method: A systematic review was undertaken to identify the extent and nature of issues in recording…

This study was designed to identify a continuum of orthographic features that characterize Spanish spelling development in Grades 1-3. Two research questions guided this work: (1) Is there a hierarchy of orthographic features that affect students' spelling accuracy in Spanish over and above other school-level, student-level, and word-level…

The goal of this study was to test the item-based assumption of the self-teaching hypothesis by reanalyzing Cunningham's (2006) data. In Cunningham's study, 37 first graders participated in a self-teaching experiment, and their orthographic learning was measured by a spelling task and an orthographic choice task. A 2-level logistic regression…

We investigated intra-individual monitoring and regulation in learning from text in sixth-grade students and their teachers. In Experiment 1, students provided judgments of learning (JOLs) for six texts in one of three cue-prompt conditions (after writing delayed keywords or summaries or without a cue prompt) and then selected texts for restudy.…

Since its introduction in the late 1990s, the unskilled and unaware effect motivated several further studies. As it stands, low-performing students are assumed to provide inaccurate and overconfident performance judgments. However, as research with second-order judgments (SOJs) indicates, they apparently have some metacognitive awareness of this.…

Authenticity is often supposed to play an important role in natural history museums. Yet we know very little about how it affects the perception and appreciation of museum objects. In the present study, we examined children's perceptions of real fossils and replicas. We explored four potential explanations underlying the appreciation of authentic…

The accuracy of decision rules for progress monitoring data is influenced by multiple factors. This study examined the accuracy of decision rule recommendations with over 4,500 second-and third-grade students receiving a tier II reading intervention program. The sensitivity and specificity of three decision rule recommendations for predicting…

This study was conducted to analyze potential item parameter drift (IPD) impact on person ability estimates and classification accuracy when drift affects an examinee subgroup. Using a series of simulations, three factors were manipulated: (a) percentage of IPD items in the CAT exam, (b) percentage of examinees affected by IPD, and (c) item pool…

Memory plays a key role in learning, and it is therefore important that teachers understand its workings in order to make decisions that benefit learning. However, previous research has shown that memory is an area which is subject to misconceptions. This study used an online survey with a five-item Likert scale to determine teachers' responses to…

We report the 1st example of a true complementarity effect in memory development--a situation in which memory for the "same event" simultaneously becomes more and less accurate between early childhood and adulthood. We investigated this paradoxical effect because fuzzy-trace theory predicts that it can occur in paradigms that produce…

Purpose: This study investigated the impact of lexical characteristics on the intelligibility of speakers with Parkinson's disease (PD). Intelligibility was compared for listening in a quiet versus a noisy environment. Method: A total of 192 young listeners participated in the study, with 96 listeners listening in quiet and 96 listening in noise…

Spatial visualization--the ability to mentally imagine and manipulate objects--has frequently been measured using the Paper Folding Test (PFT). In this task, participants view diagrams of a paper being folded and a hole being punched. They then identify the resulting punch pattern. Although task instructions promote mentally unfolding the paper,…

Vowel nasality is the most controversial phonological aspect of Brazilian Portuguese. Scholars suggest the oral-nasal vowel distinction may not exist. A consonant-like nasal resonance presence at the vowel's right edge (the nasal appendix) might make nasal vowels the product of a contextual vowel nasalization rule. Others suggest that the appendix…

Adults with developmental disabilities may not learn the safety skills needed to maintain the safety of those within their communities. Basic life-saving skills are valued by community members and increase independent and integrated living and employment opportunities. This study used an instructional package consisting of modeling, task analysis,…

Latent change score models (LCS) are conceptually powerful tools for analyzing longitudinal data (McArdle & Hamagami, 2001). However, applications of these models typically include constraints on key parameters over time. Although practically useful, strict invariance over time in these parameters is unlikely in real data. This study…
