Incentives can decrease performance by undermining intrinsic motivation. How such an interplay of external reinforcers and internal self-regulation influences memory processes, however, is less known. Here, we investigated their interaction on memory performance while learning the meaning of new-words from their context. Specifically, participants…

Background: Research in word-finding difficulties is sparse, especially in languages other than English. As a result, the factors associated with the frequency of word-finding behaviours are poorly understood, particularly in discourse. Aims: This exploratory study is the first to collect data relative to the expected frequency of word-finding…

Instructors assess the acquisition of new skills by delivering blocks of trials containing multiple operants. Mastery is evaluated as percentage correct across all operants in the block. The purpose of the current study was to investigate this traditional mastery criterion arrangement compared to an analysis of mastery at the level of individual…

Early literacy skills are essential for children's academic development. This research used a comprehensive approach that included observations, assessments, and interviews with children and educators from various kindergartens, which involved 1040 children and 99 teachers from 71 early childhood institutions. The comparison of difficulties in…

In everyday life, children hear but also often see their caregiver talking. Children build on this correspondence to resolve auditory uncertainties and decipher words from the speech input. As they hear the name of an object, 18- to 30-month-olds form a representation that permits word recognition in either the auditory (i.e. acoustic form of the…

Children can learn words incidentally from stories. This kind of learning is enhanced when stories are presented both aurally and in written format, compared to just a written presentation. However, we do not know why this bimodal presentation is beneficial. This study explores two possible explanations: whether the bimodal advantage manifests…

This dissertation examines native speakers' word recognition of, differentiation between, and social attitudes toward varieties of Arabic. It is a particularly interesting test case because of the Arabic unique regional variation situation and the available literature lacks data on how Arabic speakers perceive different accents, with a particular…

While known to influence visual lexical processing, the semantic information we associate with words has recently been found to influence auditory lexical processing as well. The present work explored the influence of "semantic richness" in auditory lexical decision. Study 1 recreated an experiment investigating semantic richness effects…

Multilingual speakers can find speech recognition in everyday environments like restaurants and open-plan offices particularly challenging. In a world where speaking multiple languages is increasingly common, effective clinical and educational interventions will require a better understanding of how factors like multilingual contexts and…

Purpose: One challenge to the design and delivery of effective vocabulary intervention is the selection of vocabulary targets. The purpose of this study was to examine the relation of word characteristics to vocabulary learning from explicit vocabulary intervention. Method: This study was a secondary analysis of data from two recent efficacy…

Purpose: Recent work suggests that speech perception is influenced by the somatosensory system and that oral sensorimotor disruption has specific effects on the perception of speech both in infants who have not yet begun to talk and in older children and adults with ample speech production experience; however, we do not know how such disruptions…

The current study is an exploration of the association between the characteristics of students' written compositions and their reading comprehension performance. We address the empirical question about the degree to which writing is predictive of reading comprehension by comparing the utility of several popular written composition metrics. These…

Unlike other visual objects which are invariant to the left-right orientation, mirror letters (e.g., b and d) represent different object identities. Previous masked priming lexical decision studies have suggested that the identification of a mirror letter involves suppression of its mirror image counterpart reporting as evidence that a pseudoword…

Most second language assessment researchers agree that interactional competence (IC) is an important part of the construct of oral communication. However, measurement of IC has proven challenging because at least one interlocutor is considered necessary to create an appropriate social context for test takers to demonstrate their IC. Including…

Studies have reported the importance of intervention programs to support early literacy in preschool. However, very few studies have tested the efficacy of intervention programs based on the syllabic method. This study aims to evaluate the effectiveness of a novel computer-based program based on the syllabic method for preschoolers (the Simo-syl…
