The construct validity of grammaticality judgment tests as measures of implicit and explicit knowledge

Abstract: Grammaticality judgment tests (GJTs) have been, and continue to be, frequently used in the field of SLA as a measure of learners’ linguistic ability in the second language (L2). However, only a few studies have examined their construct validity as measures of implicit and explicit knowledge (Bowles, 2011; R. Ellis, 2005), and even fewer have explored in detail how features of these tests, such as time pressure and task stimulus, affect their construct validity (Loewen, 2009). The purpose of this paper is to examine the effect that time pressure and task stimulus have on the type of knowledge representations on which L2 learners draw when performing GJTs. The results show that the grammatical and ungrammatical sections of a timed and an untimed GJT loaded differently in both exploratory and confirmatory factor analyses. This finding can be interpreted as indicating that grammatical and ungrammatical sentences constitute measures of implicit and explicit knowledge, respectively. Additionally, the results show that time pressure and task stimulus have significant effects on learners’ performance on GJTs.

Sampling properties of estimators of the log‐logistic distribution with application to Canadian precipitation data

Abstract: We consider the probability-weighted moment and the maximum-likelihood estimators of two parameters in the log-logistic distribution. Quantile estimators are obtained using both methods. The distributional properties of these estimators are studied in large samples, via asymptotic theory, and in small and moderate samples, via Monte Carlo simulation. The distribution is shown to be appropriate for a wide variety of meteorological data.

Stable isotope profiles of large marine predators: Viable indicators of trophic position, diet, and movement in sharks?

Abstract: Understanding the role of predators is challenging but critical for ecosystem management. For community dynamics, predator-specific size-based variation in diet, trophic position, and habitat use a...
