Inner speech as a retrieval aid for task goals: the effects of cue type and articulatory suppression in the random task cuing paradigm.

چکیده
Articulatory suppression has been shown to increase switch costs in the list paradigm (e.g., [J. Exp. Psychol.: General 130 (2001) 641, J Memory Language 48 (2003) 148]). The present dual-task study examined whether this effect generalizes to the random task cuing paradigm. Participants performed color or shape judgments according to explicit word cues (COLOR or SHAPE) or less transparent letter cues ( C for the color task and S for the shape task). In the word cue condition, the switch cost was equivalent for the articulatory suppression and the control (no dual-task) conditions, but, in the letter cue condition, the switch cost was significantly greater for the articulatory suppression condition than for the control condition. These results suggest that inner speech may be recruited as a tool for retrieving and activating the relevant task goal when the task cue is not transparent and hence imposes nonnegligible retrieval demand.

Designing and Evaluation of Reliability and Validity of Visual Cue-Induced Craving Assessment Task for Methamphetamine Smokers
A B S T R A C TIntroduction: Craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. In this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. Methods: First a series of visual cues which could induce craving was identified by 5 discussion sessions b...
متن کاملThe roles of private speech and inner speech in planning during middle childhood: evidence from a dual task paradigm.
Children often talk themselves through their activities, producing private speech that is internalized to form inner speech. This study assessed the effect of articulatory suppression (which suppresses private and inner speech) on Tower of London performance in 7- to 10-year-olds, relative to performance in a control condition with a nonverbal secondary task. Experiment 1 showed no effect of ar...
متن کاملDirect and Indirect Measures of Attention Indicate a Bias Toward Cues in Methamphetamine Users
Introduction:This study aims to investigate the attentional bias toward drug-related stimuli along with subjective craving after encountering such stimuli in methamphetamine users. Studies of cue reactivity have confirmed bias in attention and gaze to drug-related stimuli for most substances, but methamphetamine drugs are less studied by a direct measure such as eye tracking. Methods:Thirty ma...
متن کاملThe Effect of Training and Task-Planning on the Complexity of Iranian Learners’ Oral Speech
The shift of emphasis away from written to oral skills has stimulated an incipient concern in second language research to investigate ways of helping second and foreign language learners achieve higher degrees of oral proficiency. Priority solely taken over accuracy, complexity, or fluency of speech might be justifiable with regard to the context in which learning takes place. Accuracy and com...
متن کاملIs performance in task-cuing experiments mediated by task set selection or associative compound retrieval?
Task-cuing experiments are usually intended to explore control of task set. But when small stimulus sets are used, they plausibly afford learning of the response associated with a combination of cue and stimulus, without reference to tasks. In 3 experiments we presented the typical trials of a task-cuing experiment: a cue (colored shape) followed, after a short or long interval, by a digit to w...
