Dissociating sources of dual-task interference using human electrophysiology.
In the psychological refractory period (PRP) paradigm, two unmasked targets are presented, each of which requires a speeded response. Response times to the second target (T2) are slowed when T2 is presented shortly after the first target (T1). Electrophysiological studies have previously shown that the P3 event-related potential component is not delayed during T2 response slowing in the PRP par...
متن کاملThe Effect of Dual Task Interference on Gait in Aging: Role of Working Memory Components
The purpose of the present study was to investigate the effect of concurrent cognitive tasks activating phonological loop and visuospatial scratchpad of working memory on gait in older adults.12 older adults with the age range of 65-70 years performed walking trials in 3 counterbalanced testing conditions including single walking, walking while performing visuospatial task and walking while per...
متن کاملRunning head : DUAL - TASK INTERFERENCE WITH EQUAL TASK EMPHASIS Dual
Most studies using the Psychological Refractory Period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To address the possibility that central operations can proceed in parallel, albeit with capacity limitations,...
متن کاملWORKING MEMORY AND DUAL - TASK INTERFERENCE 1 Working Memory Capacity and Dual - Task Interference in Picture
Researchers have found no agreement on whether dual-task interference in language performance, such as dual-task interference from tone discrimination on picture naming, reflects passive queuing or active scheduling of processes for each task. According to a passive-queuing account, while a central response-selection bottleneck is occupied by the tone discrimination task, picture naming is held...
متن کاملVisual encoding of patterns is subject to dual-task interference.
Two stimuli were presented at varying stimulus onset asynchronies (SOAs), with each stimulus associated with a distinct task. The first stimulus was a tone at one of either two or three frequencies. In two conditions, the task associated with a tone was either a speeded two-alternative discrimination (2AD), or a speeded three-alternative discrimination (3AD) based on the pitch of the tone. In a...
