Indirect tests of memory associations relevant to cannabis have been shown to be useful in explaining and predicting adolescent cannabis use habits. This study sought to increase the understanding of adolescent cannabis-related associative memory and cannabis use behavior over time. A longitudinal sample of alternative high school students (N =…

The present study examined phoneme awareness, phonological short term memory, letter knowledge, rapid automatized naming (RAN), and visual-verbal paired associate learning (PAL) as longitudinal predictors of spelling skills in an early phase (Grade 2) and a later phase (Grade 5) of development in a sample of 140 children learning to spell in the…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

The mental lexicon plays a central role in reading comprehension (Perfetti & Stafura, 2014). It encompasses the number of lexical entries in spoken and written language (vocabulary breadth), the semantic quality of these entries (vocabulary depth), and the connection strength between lexical representations (semantic relatedness); as such, it…

The aim of this study was to examine the combined influences of infants' attention and use of social cues in the prediction of their language outcomes. This longitudinal study measured infants' visual attention on a distractibility task (11 months), joint attention (14 months), and language outcomes (word-object association, 14 months; MBCDI…

Learning inflectional morphology is a vexing problem for second language (L2) learners. Children acquiring their native language also experience some difficulty, which results in their committing overgeneralization errors. Long after individuals have achieved a high level of proficiency in the L2, they are still plagued by uncertainty when it…

The genetic factor structure of a range of learning measures was explored in twin children, recruited in preschool and followed to Grade 2 ("N"?=?2,084). Measures of orthographic learning and word reading were included in the analyses to determine how these patterned with the learning processes. An exploratory factor analysis of the…

In the present study, we have applied a word association procedure for assessing conceptual change in science education, leaning on the presuppositions of the theory of social representations. The proposed method was applied both before and after a university population ecology course. Our results have shown that the teaching procedure can change…

Single word and continuous association test behaviors of children (mean age 15.1 years) at high (N=207) and low (N=104) risk for schizophrenia were analyzed as part of a longitudinal prospective study. (SBH)

Examines the CDI-WORDS Short Form vocabulary checklist as an index of language production. The study focuses on the associations between this short form and directly observed measures of lexical production; the associations between short-form checklists administered at different ages; the predictive associations between short form scores and…

Examined the strength of the association between language exposure estimates and vocabulary learning for simultaneous bilingual infants with differing patterns of exposure to the languages being learned. Findings revealed that the correlation was strong, even for children whose language environments changed by more than 20% between observations.…

Examines the emergence of the present perfect in the interlanguage of instructed adult learners of English as a Second Language. Findings indicate that adding a new inflection in the tense/aspect system requires establishing new form-meaning associations as well as revising existing ones. (44 references) (Author/CK)
