This study aims to describe the relationships between child-internal and child-external factors and the consonant accuracy of bilingual children. More specifically, the study looks at internal factors: expressive and receptive vocabulary, and external factors: language exposure and language status, of a group of 4-year-old bilingual Arabic-French…

Valid data are essential for making correct theoretical and practical implications. Hence, efficient methods for detecting and excluding data with dubious validity are highly valuable in any field of science. This paper introduces the idea of applying autocorrelation analysis on self-report questionnaires with single-choice numbered, preferably…

In present-day digital environments, people frequently encounter content from sources of questionable trustworthiness. Advertising is an untrustworthy source because its purpose is to persuade consumers rather than to provide impartial information. One factor known to enhance the perceived truth of advertising claims is repetition: Repeated…

Public policies targeting individuals based on need often impose disproportionate burden on communities that lack the resources to implement these policies effectively. In an elementary school setting, I examine whether community-level interventions focusing on similar needs and providing resources to build capacity in these communities could…

Misinformation is one society's most pressing issues, spreading division and chaos across the globe. Videogames have become one of the more promising mediums for misinformation interventions, teaching players common falsehood indicators and helping them develop their discernment abilities. This thesis details the design, playtesting, and…

Do international large-scale assessments influence education policy? How? Through scripts, lessons, or incentives? For some, they all produce similar outcomes. For others, different assessment data, shaped by different designs, and mediated by international organizations' (IOs) policy directives, prompt different policy decisions. For some,…

Online credit recovery (OCR) refers to online courses that high school students take after previously failing the course. Many have suggested that OCR courses are helping students to graduate from high school without corresponding increases in academic skills. This study analyzes administrative data from the state of North Carolina to evaluate the…

One of the best-known demonstrations of long-term learning through repetition is the Hebb effect: Immediate recall of a memory list repeated amidst nonrepeated lists improves steadily with repetitions. However, previous studies often failed to observe this effect for visuospatial arrays. Souza and Oberauer (2022) showed that the strongest…

Context information can guide cognitive control, but both the extent and the underlying processes are poorly understood. Previous studies often found that the congruency sequence effect (CSE) is larger when perceptual context features (e.g., modality and format) of task-related distractors and targets repeat compared to change. However, it is…

Purpose: Despite the clinical utility of sentence production and sentence repetition to identify language impairment in autism, little is known about the extent to which these tasks are sensitive to potential language variation. One promising method is strategic scoring, which has good clinical utility for identifying language impairment in…

The efficacy of fake news corrections in improving memory and belief accuracy may depend on how often adults see false information before it is corrected. Two experiments tested the competing predictions that repeating fake news before corrections will either impair or improve memory and belief accuracy. These experiments also examined whether…

Past research indicates that people judge repeated statements as more true than new ones. An experiential consequence of repetition that may underly this "truth effect" is processing fluency: Processing statements feels easier following their repetition. In three preregistered experiments (N = 684), we examined the effect of merely…

Purpose: Children with residual speech sound disorders (RSSD) have shown differences in neural function for speech production, as compared to their typical peers; however, information about how these differences may change over time and relative to speech therapy is needed. To address this gap, we used functional magnetic resonance imaging (fMRI)…

Phonological duration differences in quantity languages can be problematic for second language learners whose native language does not use duration contrastively. Recent studies have found improvement in the processing of non-native vowel duration contrasts with the use of listen-and-repeat training, and the current study explores the efficacy of…

We investigated the comorbidity of low language and reading skills in 6- to 8-year-old monolingual Polish-speaking children (N = 962) using three different approaches: norming data to determine the prevalence of co-morbid difficulties, group comparisons of profiles on key cognitive-linguistic measures, and a case series analysis examining the…
