The authors used eye-tracking to compare the results of timed and untimed grammaticality judgment tests in R. Ellis (2005) and non-native English speakers with and without time pressure, and found that time pressure suppressed regressions in nonnative speakers only.
Abstract
Grammaticality judgment tests (GJTs) have been used to elicit data reflecting second language (L2) speakers’ knowledge of L2 grammar. However, the exact constructs measured by GJTs, whether primarily implicit or explicit knowledge, are disputed and have been argued to differ depending on test-related variables (i.e., time pressure and item grammaticality).Using eye-tracking, this study replicates the GJT results in R. Ellis (2005). Twenty native and 40 nonnative English speakers judged sentences with and without time pressure. Analyses revealed that time pressure suppressed regressions (right-to-left eye movements) in nonnative speakers only. Conversely, both groups regressed more on untimed, grammatical items. These findings suggest that timed and untimed GJTs measure different constructs, which could correspond to implicit and explicit knowledge, respectively. In particular, they point to a difference in the levels of automatic and controlled processing involved in responding to the timed and untimed tests. Furthermore, untimed grammatical items may induce GJT-specific task effects.

Examining the effects of crosslinguistic awareness on the acquisition of English possessive determiners: the case of Brazilian Portuguese speakers

TL;DR: The authors investigated the PD interlanguage of Brazilian Portuguese (BP) speakers and found that learners with awareness of the cross-linguistic dele/dela rule outperformed those who were unaware of the rule on two of the three tasks that were compared.

Influence of L1 Properties and Proficiency on the Acquisition of Gender Agreement

TL;DR: In this paper, the influence of L1 properties and proficiency level on the acquisition of the Spanish gender agreement system was investigated in French and English learners of Spanish, who were divided into four different groups considering their L1 (French and English) and their proficiency level.

Explicit Knowledge of the Spanish Subjunctive and Accurate Use in Discrete-Point, Oral Production, and Written Production Measures

TL;DR: The authors examined whether explicit knowledge about the Spanish subjunctive is related to using this structure accurately in discrete-point measures, as well as in measures of oral and written production, and found that participants had somewhat low levels of explicit knowledge of the subjunctive, and that explicit knowledge was significantly correlated with its correct use in discrete point grammar exercises and in writing, but not in speaking.

Orienting of attention

TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.

Controlled and automatic human information processing: II. Perceptual learning, automatic attending and a general theory.

TL;DR: Tested the 2-process theory of detection, search, and attention presented by the current authors (1977) in a series of experiments and demonstrated the qualitative difference between 2 modes of information processing: automatic detection and controlled search.
