Age Differences in Cortical Activity Associated with Preparation to Respond
Correlations between the amplitudes and latencies of the slowly developing negative potential called the contingent negative variation (CNV) and performance in two tasks requiring motor response were studied. Time estimation and forewarned reaction time tasks were used with preparatory intervals of...

| description | Correlations between the amplitudes and latencies of the slowly developing negative
potential called the contingent negative variation (CNV) and performance in two
tasks requiring motor response were studied. Time estimation and forewarned reaction
time tasks were used with preparatory intervals of 2, 4, and 8 sec duration.
Youngyoung, young-old, and old-old groups of females were tested. The hypothesis
that deficits in time estimation ability in the elderly might help to account for
age differences in performance in reaction time was investigated. Significant age
and interval related differences in the correlation between time estimation ability
and reaction time performance were found. The findings are discussed in terms of
thefr potential significance for developmental research and clinical assessment. |
