Separating Sustained From Transient Aspects of Cognitive Control During Thought Suppression.
A study was conducted to test two theories of how people regulate their thoughts. Data were obtained from tests involving 17 right-handed, native English speakers who were scanned while undertaking blocks of tasks. During suppress blocks, subjects attempted to avoid thinking about the target objec...

Data were obtained from tests involving 17 right-handed, native English speakers who were scanned while undertaking blocks of tasks. During suppress blocks, subjects attempted to avoid thinking about the target object of a white bear for 120 seconds; during free thought blocks, they were free to think about any topic, including the bear; and these blocks were separated by periods of a manual-response task. Findings indicated support for both cognitive and neural models of control. Findings revealed that dorsolateral prefrontal cortex demonstrated sustained increases in brain activation during suppression blocks; bilateral anterior cingulate cortex demonstrated transient increases associated with occurrences of unwanted thoughts. Findings are discussed in detail. pubtype: Periodical doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
