Effects of increased response dominance and contextual disintegration on the Stroop interference effect in older adults

Article Abstract:

The relative speed of processing-automaticity (RSOP-A) and contextual disintegration models were utilized to examine the age-related increase in Stroop effect or Stroop interference effect in older adults. It was hypothesized that Stroop effect indicated the increase in response latency related to color word and incongruent color word naming. Results of the experiments showed that response dominance was higher in older than younger adults which led to increased reliability in color-naming latency. Also, the prefrontal cortex played a role in Stroop interference.

Age-related decline in prospective memory: The roles of cue accessibility and cue sensitivity

Article Abstract:

A prospective memory task with a large number of observations where latency response would be the main measure, was developed. A cover task was developed where individuals could make semantic category judgments of pairs of words. Momentary lapses of intention (MLIs) were greater than zero in the first experiment, suggesting that performance fluctuated during the course of the task. Older adults demonstrated higher response latency (RL) for missed prospective cues, and responded slower to prospective cues than younger adults.

Neural correlates of age-related declines in the formation and realization of delayed intentions

Article Abstract:

Neural correlates of age-related declines in prospective memory were studied by using event-related brain potentials in a task in which individuals formed and later realized simple intentions. The behavioral data revealed that prospective responding was less accurate and slower in older than in younger adults.
