The present study compared the performance of two groups of second language learners processing three linguistic structures in Spanish. The linguistic targets were passives, object pronouns in O[subscript pro]VS sentences, and gender-cued null subjects in subordinate clauses. The primary differences between the two groups were language experience…

In seeking to both confirm previous conclusions and expand the literature of the field with a different group of participants, McNulty (2012) was (partially) replicated. Three instructional interventions were designed to ascertain which activity type was responsible for learner gains. One treatment group (R) included referential-only practice…

The purpose of this paper is to compare structured input (SI) with other input-based instructional treatments. The input-based instructional types include: input flood (IF), text enhancement (TE), SI activities, and focused input (FI; SI without implicit negative feedback). Participants included 145 adult learners enrolled in an intermediate…

Motivated by predictions of the theory of Input Processing, this study adds to previous research on second language (L2) Spanish pronunciation learning by investigating the impact of two distinct types of pronunciation assignments on first language (L1) English L2 Spanish students' improvement in pronunciation of the vowels /e, o/. Two sections of…

In this article, we examine whether the effectiveness of processing instruction (PI) is limited to forms targeted in the instructional treatment (primary effects) or whether it also extends to other forms (transfer-of-training effects). L2 Spanish learners (N = 123) received either PI or traditional instruction (TI) targeting third-person…

This study examines the effects of processing instruction (PI) alone versus PI and output (O) on the acquisition of three conjunctional and infinitival phrases in Spanish. Seventy intermediate and advanced-intermediate high school participants received: 1) PI on three consecutive days (PI + PI + PI); 2) PI for two days and meaning-based output…

In the present study, we examine the roles of 1) explicit information about language provided to learners prior to treatment and 2) aptitude (specifically grammatical sensitivity) within Processing Instruction. Forty-two learners of Spanish in their third-semester of study were divided into two groups: those who received explicit information (EI)…

Research on Processing Instruction (PI) has yielded consistently positive results across a variety of measures. In addition, in comparison to other instructional interventions, PI tends to yield superior results. The one difference is comparative research with Meaning-based Output Instruction (MOI) in which in a number of studies, MOI is seen to…
