Recall Procedure

The role of interference as an age-related variable in RI and PI as a function of anticipation interval and transfer paradigm was studied by employing different transfer paradigms (A-B, A-C; A-B, C-B; A-B, C-D), and by varying the anticipation interval (2 sec. or 4 sec.). 60 young ( M = 27.42 yr.) and 60 elderly adults ( M = 68.73 yr.) learned 2 lists of paired adjectives to an 8/8 criterion and then recalled the lists by means of a written modified method of free recall. Significant age differences in RI and PI were found, with the old Ss showing disproportionately more RI under the 2-sec. A-B, A-C high interference condition. Neither anticipation interval nor transfer paradigm contributed to age differences in PI. Results indicated that adult age differences in RI and PI as measured by the unpaced modified free-recall procedure essentially agree with those in RI and PI studies using relearning and paced recall tests.

Adult Age Differences

Facial expressions are powerful communicative social signals that motivate feelings and action in the observer. However, research on incentive motivation has overwhelmingly focused on money and points and the limited research on social incentives has been mostly focused on responses in young adulthood. Previous research on the age-related positivity effect and adult age differences in social motivation suggest that older adults might experience higher levels of positive arousal to socioemotional stimuli than younger adults. Affect ratings following dynamic emotional expressions (anger, happiness, sadness) varying in magnitude of expression showed that higher magnitude expressions elicited higher arousal and valence ratings. Older adults did not differ significantly in levels of arousal when compared to younger adults, however their ratings of emotional valence were significantly higher as the magnitude of expressions increased. The findings provide novel evidence that socioemotional incentives may be relatively more reinforcing as adults age. More generally, these dynamic socioemotional stimuli that vary in magnitude are ideal for future studies of more naturalistic affect elicitation, studies of social incentive processing, and use in incentive-driven choice tasks.

Application Component

The purpose of the current project was to examine the nature of the age-related differences on the Raven's Advanced Progressive Matrices (APM). Three components were hypothesized to be involved in correctly solving the APM problems. These included a rule-identification component, a rule-application component (involving a one-rule spatial transformation), and a rule-coordination component. The project was designed to examine the influence of each of the hypothesized components on the age-related variance on the APM. Two tests presumed to measure each hypothesized component were presented to 183 adults between the ages of 21 and 83. Hierarchical regression analyses indicated that although all of the hypothesized components accounted for a significant amount of the variance on the APM (approximately 50% each), only performance on the tasks measuring rule application accounted for a unique proportion of the age-related variance on the APM. Implications of the results in regards to following symbolic instructions in assembly of objects and in driving are discussed.

Age Related Changes

PurposeThe study was aimed at characterizing age-related changes in speech motor performance on a nonword repetition task as a function of practice and nonword length and complexity.MethodNonword repetition accuracy, lip aperture coordination, and nonword production durations were assessed on 2 consecutive days for 16 young and 16 elderly participants for the production of 6 novel nonwords increasing in length and complexity.ResultsThe effect of age on the ability to accurately and rapidly repeat long, complex nonwords was significant. However, the authors found no differences between the speech motor coordinative patterns of young and elderly adults. Further, the authors demonstrated age- and nonword-specific within- and between-session gains in speech motor performance.ConclusionsThe authors speculate that cognitive, sensory, and motor factors interact in complex ways in elderly individuals to produce individual differences in nonword repetition ability at the levels of both behavioral and speech motor performance.

Visual Scenes

Abstract This study investigated age differences in false memory for visual scenes and the effect of immediate recall on subsequent recognition. Eighty children (7–9 years), 74 adolescents (14–16 years), 92 young adults (19–26 years) and 82 older adults (50–80 years) studied four visual scenes and then took a recognition test after either a free-recall task or a filler task. Results showed an age-related decline in false recognition for visual scenes, but this trend was eliminated when participants were asked to free-recall before recognition. Prior recall decreased false recognition in children, but increased false recognition in older adults. Across the lifespan, adolescents had the loosest criterion, children had the lowest false recall, and prior recall increased true recognition in older adults.

Potential Moderator

To the extent that adult age differences in measures of cognitive performance have implications for functioning outside the psychological laboratory, the question of the role of experience as a potential moderator of these differences becomes extremely important. Three categories of research relevant to this issue are reviewed, and methodological limitations of each type of research are discussed. Although it is frequently asserted that experience minimizes cognitive differences associated with aging, the evidence currently available does not appear consistent with a strong experiential moderation of age-related effects in cognitive performance. However, the paucity of relevant studies and the methodological weaknesses of those that do exist preclude a definitive conclusion at the present time. Additional research with improved methodology is necessary before strong conclusions can be reached concerning effects of experience on age differences in cognition.
