Dissociating controlled from automatic processing in temporal preparation

Dissociating controlled from automatic processing in temporal preparation.

The aim of the present study was to investigate the controlled versus the automatic nature of temporal preparation. If temporal preparation involves controlled rather than automatic processing, it should be reduced by the addition of a concurrent demanding task. This hypothesis was tested by comparing participants' performance in a temporal preparation task that measured two main effects of tem...

Response preparation in Parkinson's disease: automatic vs. controlled processing.

Using a finger cuing paradigm, we investigated response preparation in Parkinson's disease (PD). The central question was whether PD individuals are differentially affected by preparatory cues that specify a more automatic response set configuration (that induces within-hand preparation) as opposed to a more controlled one (that induces between-hands preparation). Reaction times (RTs) and error...

Dissociating Automatic and Consciously Controlled Effects of Study/Test Compatiblity

Two experiments examined the effects of reinstated context on consciously controlled and automatic influences of memory. Results showed that reinstating associative context had separate effects of enhancing both controlled and automatic influences. In contrast, dividing attention during study reduced later recollection, a consciously controlled use of memory, but left automatic influences uncha...

Dissociating Neural Mechanisms of Temporal Sequencing and Processing Phonemes

Using fMRI, we sought to determine whether the posterior, superior portion of Broca's area performs operations on phoneme segments specifically or implements processes general to sequencing discrete units. Twelve healthy volunteers performed two sequence manipulation tasks and one matching task, using strings of syllables and hummed notes. The posterior portion of Broca's area responded specifi...
