Creative Interpretations of Novel Conceptual Combinations in Aging

Conceptual combinations may be interpreted by 3 main strategies: by attributing a feature of the modifying (head) noun into the modified noun (property interpretation); by establishing a relation between the 2 concepts (relational interpretation); or by combining properties of both nouns into a concept with new identity (hybridization). There exists limited evidence regarding the quality of interpretations older adults provide to novel conceptual combinations, and especially to novel metaphoric phrases. This study aimed to evaluate and compare age differences in strategies adopted for comprehending conceptual (noun noun) combinations. The aim of this study was, therefore, to examine the impact of aging on the ability to generate novel and creative semantic interpretations to unfamiliar word pairs. Participants included 41 healthy younger (mean age = 25.1) and 40 healthy older adults (mean age = 75.3). Participants were asked to write interpretations to novel metaphoric and meaningless noun-noun phrases. Relative to young adults, older participants generated more creative (hybridization) interpretations to novel metaphor and meaningless combinations. The second finding indicated that older adults generated fewer relational interpretations to the meaningless compounds. The results suggest that, relative to young adults, older adults generate more creative and highly integrative interpretations to conceptual combinations.

Effects of age on navigation strategy

Age differences in navigation strategies have been demonstrated in animals, with aged animals more likely to prefer an egocentric (route) strategy and younger animals more likely to prefer an allocentric (place) strategy. Using a novel virtual Y-maze strategy assessment (vYSA), the present study demonstrated substantial age differences in strategy preference in humans. Older adults overwhelmingly preferred an egocentric strategy, while younger adults were equally distributed between egocentric and allocentric preference. A preference for allocentric strategy on the Y-maze strategy assessment was found to benefit performance on an independent assessment (virtual Morris water task) only in younger adults. These results establish baseline age differences in spatial strategies and suggest this may impact performance on other spatial navigation assessments. The results are interpreted within the framework of age differences in hippocampal structure and function.

Metacognitive monitoring and strategic behaviour in working memory performance

Research indicates that cognitive age differences can be influenced by metacognitive factors. This research has generally focused on simple memory tasks. Age differences in working memory (WM) performance are pronounced, but are typically attributed to basic cognitive deficits rather than metacognitive factors. However, WM performance can be influenced by strategic behaviour that might be driven by metacognitive monitoring. In the current project, we attempted to connect these lines of research by examining age differences in metacognitive WM monitoring and strategies. In Experiment 1, younger and older adult participants completed a computerized operation span task in conditions that either required or did not require monitoring reports. Participants in the monitoring condition predicted and postdicted global performance for each block and rated their responses following each trial within a block. In Experiment 2, participants also reported their trial-level strategic approach. In contrast to the age equivalence typically found for simple memory monitoring, results demonstrated age differences in WM monitoring accuracy. Overall age differences in strategy use were not found, but using effective strategies benefited older adults' performance more than younger adults'. Furthermore, age-related differences in the WM task appear to be mediated by the accuracy of performance monitoring.

Age Differences in Understanding Peace, War, and Conflict Resolution

Children's and adolescents' understanding of conflict and strategies for peace were assessed in response to concerns raised during the Gulf War. The sample comprised 156 schoolchildren aged 7-18 years. Major findings included a unilinear developmental progression in understanding the concept of war and peace. There was a tendency for the younger children to have concepts of war which broadly incorporated many negative aspects and to cite government rather than individuals as having responsibility for ensuring peace. The older children were more likely than the younger children to express the belief that there should be no intervention in others' conflicts. Age differences in strategies for resolving conflict and establishing peace between individuals were found to be greater than developmental differences in strategies for conflict and peace between countries. There was little evidence for assuming that children develop a strategy for resolving conflicts which is generalised across interpersonal and international domains. Across ages, the concept of peace was specified less well than the concept of war, although the overall patterns of findings suggest that most children understand peace.
