Skill acquisition theorists conceptualize second language (L2) learning as the acquisition of a set of perceptual, cognitive, and motor skills. The dominant view in skill acquisition theory is to regard L2 skill acquisition as a three-stage process "from initial representation of knowledge through initial changes in behavior to eventual…

This dissertation presents various machine learning applications for predicting different cognitive states of students while they are using a vocabulary tutoring system, DSCoVAR. We conduct four studies, each of which includes a comprehensive analysis of behavioral and linguistic data and provides data-driven evidence for designing personalized…

Humans have the remarkable capacity to learn words from a single instance. The goal of this study was to examine the impact of initial learning context on the understanding of novel word usage using event-related brain potentials. Participants saw known and unknown words in strongly or weakly constraining sentence contexts. After each sentence…

This study aims at arousing college students' metacognition in detecting lexical cohesion during online text construction as WordNet served as a lexical resource. A total of 83 students were requested to construct texts through sequences of actions identified as interaction chains in this study. Interaction chains are grouped and categorized as a…

It was hypothesized that by age 8 children would manifest an adult meaning system, and that 5-year-old children would not. An adult meaning system allows an adult to transcend component word meanings and integrate, in the presence of a speaker, the underdetermined and the factual proposition into a meaningful whole. Subjects were 60 5- and…

This examination of retrieval interference in memory theories argues that relevant world knowledge can reduce interference by integrating factors learned about a concept. Three recognition experiments were conducted and two hypotheses were considered to account for the results: human associative memory and script analysis. (Author/RD)

Three experiments investigated whether abstract as well as concrete sentences can be processed in a holistic manner. Results suggest that the processing of both types of sentences involves construction of particularized, holistic mental representations that contain information and inferences based on context and knowledge of language and the…

The purpose of this study was to further investigate performance differences between reflective and impulsive subjects on a recognition memory task. Other researchers have proposed that these differences are based on visual analysis and that they are relatively independent of verbal processes. To test this contention, a sentence recognition task…

Visual and auditory processing of complex sentences was examined among 8- through 11-year-olds. Findings suggested a U-shaped learning pattern for on-line processing of restrictive relative clauses. Off-line accuracy scores showed different patterns for good and poor comprehenders. Incorrect local attachment strategy use was related to sentence…

Reports three experiments to test age-related difFerences in sentence memory arising from sources other than noncognitive factors. Age-related differences are discussed in terms of deficiencies at encoding and retrieval. (PMJ)
