For some, research in learning and teaching of a second language (L2) runs the risk of disintegrating into irreconcilable approaches to L2 learning and use. On the one side, we find researchers investigating linguistic-cognitive issues, often using quantitative research methods including inferential statistics; on the other side, we find…

The present research demonstrates that very brief variations in affect, being around 1 s in length and changing from trial to trial independently from semantic relatedness of primes and targets, modulate the amount of semantic priming. Implementing consonant and dissonant chords (Experiments 1 and 5), naturalistic sounds (Experiment 2), and visual…

This study investigates the combined effects of task-based careful online planning and the storyline structure of a task on second language performance (complexity, accuracy and fluency). Sixty intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline…

The role of awareness or consciousness in learning has been a relatively contentious issue in non-SLA fields (e.g., cognitive psychology). With the publications of Williams (2004, 2005), a similar debate appears to be brewing in the field of SLA. Contrary to Leow (2000), who reported that unawareness did not appear to play an important role in…

A number of studies have documented the cognitive outcomes associated with bilingualism. To gain a clear understanding of the extent and diversity of these cognitive outcomes, the authors conducted a meta-analysis of studies that examined the cognitive correlates of bilingualism. Data from 63 studies (involving 6,022 participants) were extracted…

Research indicates a strong relationship between phonological awareness and reading success. Phonemic intervention programs clearly show the benefits of explicitly teaching phonological awareness skills. Phonological awareness skills vary in nature and degree of difficulty and appear to follow a developmental progression. This study examined a…

Clark's arguments for treating language materials as random rather than fixed effects are examined, and the problems with random effects designs and approximate statistical tests (quasi F-ratios) are reviewed. It is suggested that researchers use fixed factors. (Author/RM)

Describes a computational model of high-dimensional context space: the Hyperspace Analog to Language (HAL). Shows that HAL provides sufficient information to make semantic, grammatical, and abstract distinctions. Demonstrates the cognitive compatibility of the representations with human processing; and introduces a new methodology that extracts…

Offers an introduction to the theory and implementation of Latent Semantic Analysis (LSA), a theory and method for extracting and representing the contextual-usage meaning of words by statistical computations applied to a large corpus of text. Gives an overview of applications and modeling of human knowledge to which LSA has been applied. (SR)

Comments on several quantitative approaches to semantic knowledge representations (the focus of this special issue). Points out some of the ways in which Latent Semantic Analysis and Hyperspace Analog to Language fall short of being plausible theories about psychological reality. Examines in-principle failures and wrong-kind failures that arise in…

The properties of four different tests of the treatment effect in experiments using linguistic materials are examined. (Author/RM)

Illustrates use of Latent Semantic Analysis (LSA) for predicting coherence through reanalyzing two studies that manipulated coherence of texts and assessed readers' comprehension. Finds that LSA predicts effects of text coherence on comprehension. Notes that LSA can be applied as an automated method that produces coherence predictions similar to…

Focuses on Elman's (1990) statistical analyses of the hidden unit activation patterns in his simple recurrent network on sentence prediction, first to highlight the feasibility of such analyses and then to show how connectionist explanations contribute to the development of effective explanatory theories. Argues for the evolutionary nature of…

Replicates R. P. Leow's 1993 study on the effects of simplification, type of linguistic item, and second/foreign language experience on learners' intake of linguistic items contained in written output. Results on the type of linguistic item underscore the need for research to consider seriously the role of modality while addressing cognitive…
