Memory decision-making in 26- to 32-month-olds was investigated using visual-paired comparison paradigms, requiring toddlers to select familiar stimuli (Active condition) or view familiar and novel stimuli (Passive condition). In Experiment 1 (N = 108, 54.6% female, 62% White; replication N = 98), toddlers with higher accuracy in the Active…

The effects of fluency-based instruction and accuracy-based instruction on contingency adduction were assessed using an alternating treatments design. Stimulus equivalence tasks were used to measure contingency adduction. Stimulus classes were composed of arbitrary visual forms. One treatment condition consisted of teaching fast, fluent responding…

Mirror visual feedback increases neural activity, enhances performance, and induces neuroplasticity; however, mixed results have been observed during the learning of motor skills. While mirrors are commonplace in Western dance education, further research is needed to determine how mirrors are used when learning dance phrases. This study measured…

There are two lines of discussion regarding the function of the Approximate Number System (ANS). The first line focuses on the extent to which visual cues affect the estimation of numerosity. The second line investigates the extent to which ANS precision is associated with symbolic math performance. The current study combined these two lines of…

The same-different task is a classic paradigm that requires participants to judge whether two successively presented stimuli are the same or different. While this task is simple, with results that have been replicated many times, response times (RTs) and accuracy for both same and different decisions remain difficult to model. The biggest obstacle…

Two masked priming experiments investigated the impact of prime lexicality (word vs. nonword) and the pseudo-morphological structure of prime stimuli (pseudosuffixed vs. nonsuffixed) on embedded word priming effects. In the related prime conditions, target words were embedded at the beginning of prime stimuli and were followed either by a…

Semantic diversity quantifies the similarity in the content of contexts a word has been experienced in. Four experiments investigated its effect on lexical and semantic judgments in 9- to 10-year-olds and adults. In Experiment 1, a cross-modal semantic judgment task, participants decided whether a visually presented word matched an audio…

Humans have a uniquely sophisticated ability to see past superficial features and to understand the relational structure of the world around us. This ability often requires that we compare structures, finding commonalities and differences across visual depictions that are arranged in space, such as maps, graphs, or diagrams. Although such visual…

Taken together, the Coherence Principle of Multimedia Learning Theory and the Integrated Systems Hypothesis propose that co-occurring and semantically congruent verbal and visual information should be integrated into one mental representation that enhances memory. The purpose of this paper was to examine how learning pseudowords with matching…

Purpose: The purpose of this study was to evaluate whether preschoolers with primary language impairment (PLI) show deficits in executive function (EF) compared with their peers with typical development (TD) when inhibition, updating, and mental-set shifting are examined using both linguistically based and visually based tasks. Method: Twenty-two…

Purpose: This study compared attention control and flexibility in school-age children who stutter (CWS) and children who do not stutter (CWNS) based on their performance on a behavioral task and parent report. We used a classic attention-shifting paradigm that included manipulations of task goals and timing to test effects of varying demands for…

According to some accounts, the bilingual advantage is most pronounced in the domain of executive attention rather than inhibition and should therefore be more easily detected in conflict adaptation paradigms than in simple interference paradigms. We tested this idea using two conflict adaptation paradigms, one that elicits a list-wide…

A fundamental issue in speech science concerns the extent to which speech sounds are mentally represented by articulatory-motor and/or auditory-acoustic features. This dissertation aims to expand upon the current literature by investigating changes in production and perception following visual feedback training with either articulatory or acoustic…

Strategic Incremental Rehearsal (SIR) is a recently developed flashcard intervention that blends Traditional Drill with Incremental Rehearsal (IR) for teaching sight words. The initial study evaluating SIR found it was more effective than IR for teaching sight words to first-grade students. However, that study failed to assess efficiency, which is…

Purpose: The purpose of the study was to assess the ability of children with developmental language learning impairments (LLIs) to use visual speech cues from the talking face. Method: In this cross-sectional study, 41 typically developing children (mean age: 8 years 0 months, range: 4 years 5 months to 11 years 10 months) and 27 children with…
