Changing internal constraints on action: the role of backward inhibition.

Abstract: Flexible control of action requires the ability to disengage from previous goals or task sets. The authors tested the hypothesis that disengagement during intentional shifts between task sets is accompanied by inhibition of the previous task set ("backward inhibition"). As an expression of backward inhibition the authors predicted increased response times when shifting to a task set that had to be abandoned recently and, thus, suffers residual inhibition. The critical backward inhibition effect on the level of abstractly defined perceptual task sets was obtained across 6 different experiments. In addition, it was shown that backward inhibition can be differentiated from negative priming (Experiment 2), that it is tied to top-down sequential control (Experiment 3), that it can account at least partially for "residual shift costs" in set-shifting experiments (Experiment 4), and that it occurs even in the context of preplanned sequences of task sets (Experiment 5).

Some empirical evidence for the involvement load hypothesis in vocabulary acquisition

Abstract: EFL learners in two countries participated in two parallel experiments testing whether retention of vocabulary acquired incidentally is contingent on amount of task-induced involvement. Short- and long-term retention of ten unfamiliar words was investigated in three learning tasks (reading comprehension, comprehension plus filling in target words, and composition-writing with target words) with varying “involvement loads”—various combinations of need, search, and evaluation. Time-on-task, regarded as inherent to a task, differed among all three tasks. As predicted, amount of retention was related to amount of task-induced involvement load: Retention was highest in the composition task, lower in reading plus fill-in, and lowest in the reading. These results are discussed in light of the construct of task-induced involvement.

Task-based second language learning: the uses of the first language

Abstract: The present article focuses on the uses of the first language (L1) made by 22 pairs of grade 8 French immersion students as they complete one of two different tasks: a dictogloss and a jigsaw. The outcome of each task is a story written by each student pair. We propose a coding scheme for the uses made of the L1, exemplify them, and report on exploratory analyses intended to describe differences between and within the tasks in terms of the amount of English (L1) used. We also address the relationship between the amount of L1 use and the quality of students’ writing, and the variability in task performance across student pairs.

Conducting the train of thought: working memory capacity, goal neglect, and mind wandering in an executive-control task.

Abstract: On the basis of the executive-attention theory of working memory capacity (WMC; e.g., M. J. Kane, A. R. A. Conway, D. Z. Hambrick, & R. W. Engle, 2007), the authors tested the relations among WMC, mind wandering, and goal neglect in a sustained attention to response task (SART; a go/no-go task). In 3 SART versions, making conceptual versus perceptual processing demands, subjects periodically indicated their thought content when probed following rare no-go targets. SART processing demands did not affect mind-wandering rates, but mind-wandering rates varied with WMC and predicted goal-neglect errors in the task; furthermore, mind-wandering rates partially mediated the WMC–SART relation, indicating that WMC-related differences in goal neglect were due, in part, to variation in the control of conscious thought.
