Implicit Learning In Preschool Children With And Without Developmental Language Disorder, Abigail E. Tolomei

University Honors Theses

The study below was designed to compare implicit learning in fifty-two preschool-aged children with and without developmental language disorder (DLD) to test the Procedural Deficit Hypothesis (PDH). The PDH claims that procedural memory, the basis of implicit learning, is the main impairment in DLD. Using a computer-based program to conduct sound-meaning-mapping tasks, we asked children to select one of two images according to the corresponding sound they heard. After all the participants were tested, an additional cue was found in the experiment that impacted the data. Instead of the children attuning to the sounds to depict the correct answer, the …

Explicit Learning Of Auditory Categories In Preschoolers With And Without Developmental Language Disorder, Lauren Casey

University Honors Theses

This study a part of a broader study including Quam et al. (2020) and Yu (2020) with the aim of understanding how children with and without developmental language disorder learn language. With a better understanding of the underlying learning mechanisms affected in DLD, better interventions can be implemented. The current study investigates explicit language learning in preschoolers with and without developmental language disorder (DLD). This was done by observing sound discrimination and explicit sound-meaning mapping. One child with DLD and 29 children with typical language development (TLD) participated in this study. Inclusion in each group was determined by a hearing …

Implicit Learning Of Children With And Without Developmental Language Disorder Across Auditory And Visual Categories, Wanchi Yu

Dissertations and Theses

The current study examined implicit sound- and visual-meaning-mappings of children with and without Developmental Language Disorder (DLD).

One child with DLD and 29 children with typical language development (TLD) were included in the study, based on results from a hearing screening and standardized assessments of cognitive and expressive language skills. Participants completed two computer-based experiments, which were designed to investigate: 1) sound discrimination (pitch and duration), implicit mapping of sound stimuli to objects; 2) visual discrimination, implicit mapping of visual stimuli to objects.

The current study showed that children with TLD who implicitly learned pitch categories showed better mapping of …

A Comparison Of Grammatical Morpheme Usage By Four Year Olds With Normal, Impaired, And Late Developing Language, Sally Alforde

Dissertations and Theses

The purpose of this study was to determine whether language-disordered four-year-old children and those with a history of language delay but currently normal functioning would have acquired a significantly lower percentage of 13 grammatical morphemes than children of the same age with normal language skills. Research has shown that there is a consistency of order in which these morphemes are acquired in children with normal language ability. Studies have also shown that while language disordered children acquire these grammatical morphemes in a similar order, the process is slowed down. Language disordered children have difficulty with grammatical morpheme development. Not found …

A Comparison Of Behavioral Problems Between Speech And/Or Language Impaired Children And Normal Children, Jeannie S. Botelho

Dissertations and Theses

The questions posed in this study were: 1) Is there a significant difference in the prevalence of behavioral problems between speech and/or language impaired children and normal children as reported by parents and teachers? and 2) Is there a significant difference in the types of behavioral problems between speech and/or language impaired children and normal children, as reported by parents and teachers?

Pragmatic Deficits In Normal, Articulation Disordered, And Language Delayed Samples, Karen Jean Lucas

Dissertations and Theses

The purposes of this investigation were to identify, via the Pragmatic Protocol, the incidence of pragmatic disorders within public school articulation and language caseloads and a control group of normal students and to specify the pragmatic areas, i.e., utterance propositional, and/or illocutionary/perlocutionary act categories in which deficits occur.
