The Effects Of Frontal Lobe Functioning And Age On Veridical And False Recall, Jason C.K. Chan, Kathleen B. Mcdermott

Washington University, St. Louis, Missouri Older adults’ heightened susceptibility to false memories has been linked to compromised frontal lobe functioning as estimated by Glisky and colleagues’ (Glisky, Polster, & Routhieaux, 1995) neuropsychological battery (e.g., Butler, McDaniel, Dornburg, Price, & Roediger, 2004). This conclusion, however, rests on the untested assumption that young adults have uniformly high frontal functioning. We tested this assumption, and we correlated younger and older adults’ frontal scores with veridical and false recall probabilities with prose materials. Substantial variability in scores on the Glisky battery occurred for younger (and older) adults. However, frontal scores and age were independent …

The Testing Effect In Recognition Memory: A Dual Process Account, Jason C.K. Chan, Kathleen B. Mcdermott

The testing effect, or the finding that taking an initial test improves subsequent memory performance, is a robust and reliable phenomenon--as long as the final test involves recall. Few studies have examined the effects of taking an initial recall test on final recognition performance, and results from these studies are equivocal. In 3 experiments, we attempt to demonstrate that initial testing can change the ways in which later recognition decisions are executed even when no difference can be detected in the recognition hit rates. Specifically, initial testing was shown to enhance later recollection but leave familiarity unchanged. This conclusion emerged …
Accurate Vocal Compensation For Sound Intensity Loss With Increasing Distance In Natural Environments, Pavel Zahorik, Jonathan W. Kelly
Accurate Vocal Compensation For Sound Intensity Loss With Increasing Distance In Natural Environments, Pavel Zahorik, Jonathan W. Kelly
Jonathan W. Kelly
Human abilities to adjust vocal output to compensate for intensity losses due to sound propagation over distance were investigated. Ten normally hearing adult participants were able to compensate for propagation losses ranging from −1.8 to −6.4dB/doubling source distance over a range of distances from 1 to 8m. The compensation was performed to within 1.2dB of accuracy on average across all participants, distances, and propagation loss conditions with no practice or explicit training. These results suggest that natural vocal communication processes of humans may incorporate tacit knowledge of physical sound propagationproperties more sophisticated than previously supposed.
