Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

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…

Little is explored regarding the modality-specific differences in recall abilities of preschool children. Understanding modality-specific differences in the recall at an early age might give an insight into age-linked trends, which can lay a foundation for later development. The current study used a cross-sectional design to investigate the…

The aim of this study is to design, develop, implement and evaluate an accessible mass open learning platform for visually impaired individuals. The study group consists of experts in the field who want to contribute to the study voluntarily with the snowball sampling method and have not used the platform before, with or without visual impairment.…

The development of the ability to anticipate--as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus--may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to…

Purpose: Using naturalistic synthesized speech, we determined the relative importance of acoustic cues in voice gender and age perception in cochlear implant (CI) users. Method: We investigated 28 CI users' abilities to utilize fundamental frequency (F0) and timbre in perceiving voice gender (Experiment 1) and vocal age (Experiment 2).…

Previous research suggests that toddlers can rely on distributional cues in the input to track adjacent and nonadjacent grammatical dependencies. It remains unclear whether toddlers understand the hierarchical phrase structures that determine the corresponding grammatical dependencies. We addressed this question by testing toddlers on two…

Purpose: It is not clear if behavioral indices of listening effort are sensitive to changes in signal-to-noise ratio (SNR) for young children (7-12 years old) from multilingual backgrounds. The purpose of this study was to explore the effects of SNR on listening effort in multilingual school-aged children (native English, nonnative English) as…

Purpose: Growing evidence supports the inclusion of perceptual tests that quantify the processing of temporal fine structure (TFS) in clinical hearing assessment. Many tasks have been used to evaluate TFS in the laboratory that vary greatly in the stimuli used and whether the judgments require monaural or binaural comparisons of TFS. The purpose…

Comparisons of the relative efficiency of different prompt topographies (visual or auditory), when teaching intraverbal behavior to children with disabilities, have yielded idiosyncratic results. Recent research has shown that previous exposure to a specific prompt type may affect its efficiency when teaching intraverbal behavior to preschool…

Purpose: The purpose of this study was to determine whether a new oculomotor serial reaction time (RT) task revealed statistical sequence learning in young children. Method: We used eye tracking to measure typically developing children's oculomotor RTs in response to cartoon-like creatures that appeared successively in quadrants of a monitor…

An unresolved issue regarding working memory (WM) processes relates to whether domain-general attentional resources are required to form and store bound representations. Recent evidence suggests that visual WM performance during tasks that require binding of face-scene pairs is disrupted by concurrent divided attention to a greater degree than…

Purpose: This study investigated attentional shifting in preschool children with specific language impairment (SLI) compared to their typically developing peers. Children's attentional shifting capacity was assessed by varying attentional demands. Method: Twenty-five preschool children with SLI and 25 age-matched, typically developing controls…

This pilot study tested the efficacy of auditory and visual stimuli to increase children's exercise intensity while exercising in a classroom. Nineteen children aged 6 to 12 years participated in four exercise conditions (treadmill with and without music; cycling with and without video) with heart rate monitored continuously. This study used…

We assessed nonword repetition (NWR) skills in 7-9 year-old children with dyslexia (dyslexia-only), developmental language disorder (DLD-only), co-occurring DLD+dyslexia, and typical development (TD) with a norm-referenced and an experimental task. The experimental task manipulated phonemic variability (dissimilarity among consonant phonemes…
