Age and response bias: evidence from the strength-based mirror effect.

Criss, AH

Performance in episodic memory is determined both by accurate retrieval from memory and by decision processes. A substantial body of literature suggests slightly poorer episodic memory accuracy for older than younger adults; however, age-related changes in the decision mechanisms in memory have received much less attention. Response bias, the willingness to endorse an item as remembered, is an important decision factor that contributes to episodic memory performance, and therefore understanding age-related changes in response bias is critical to theoretical development. We manipulate list strength in order to investigate two aspects of response bias. First, we evaluate whether criterion placement in episodic memory differs for older and younger adults. Second, we ask whether older adults have the same degree of flexibility to adjust the criterion in response to task demands as younger adults. Participants were tested on weakly and strongly encoded lists where word frequency (Experiment 1) or similarity between targets and foils (Experiment 2) was manipulated. Both older and younger adults had higher hit rates and lower false-alarm rates for strong lists than for weak lists (i.e., a strength-based mirror effect). Older adults were more conservative (less likely to endorse an item as studied) than younger adults, and we found no evidence that older and younger adults differ in their ability to flexibly adjust their criterion based on the demands of the task.

Age related changes in recognition memory for emotional stimuli
Kılıç, Aslı; Gökçay, Didem; Department of Cognitive Sciences (2007)
Recognition memory - a type of episodic memory in long term memory - is known in the literature to be affected by emotion, aging and the modality of the presented stimuli. The major aim of this study was to investigate whether emotional stimuli enhances recognition memory. Another goal was to observe whether modality and aging effects are present and differentiable in a non-Western subject sample. In literature, emotion studies were based on mainly two dimensions of emotions: valence and arousal. However, t...
Eye movement control in Turkish sentence reading.
Özkan, Ayşegül; Beken Fikri, Figen; Kırkıcı, Bilal; Kliegl, Reinhold; Acartürk, Cengiz (SAGE Publications, 2020-10-21)
Reading requires the assembly of cognitive processes across a wide spectrum from low-level visual perception to high-level discourse comprehension. One approach of unravelling the dynamics associated with these processes is to determine how eye movements are influenced by the characteristics of the text, in particular which features of the words within the perceptual span maximise the information intake due to foveal, spillover, parafoveal, and predictive processing. One way to test the generalisability of ...
Recognition accuracy for original and altered verbal memory reports in older adults
Dijkstra, Katinka; Mısırlısoy, Mine (SAGE Publications, 2009-02-01)
The current study examined four factors that were expected to influence recognition accuracy of previously retrieved events: remoteness of the event, rated emotionality of the event, the type of changes that were made to the original memory report, and the plausibility of these changes. This was done in a study with 33 participants who were tested for recognition accuracy of original and altered reports a year after they had initially reported these autobiographical memories. Participants evaluated original...
Aging Slows Access to Temporal Information From Working Memory
Kılıç Özhan, Aslı; Oztekin, Ilke (Oxford University Press (OUP), 2017-11-01)
To evaluate the impact of aging on controlled memory search operations, we investigated the retrieval of temporal order information from working memory (WM).
The effects of golf expertise and presentation modality on memory for golf and everyday items
Dijkstra, Katinka; MacMahon, Clare; Mısırlısoy, Mine (Elsevier BV, 2008-06-01)
The present study assessed whether golf expertise, presentation modality, and domain relevance affected memory for golf-related and everyday items. Forty-eight experienced golfers and 48 non-golfers were compared in their memory for golf-related ("putt to the hole") and everyday ("turn on the lamp") items. To-be-remembered items were presented verbally, visually, or were enacted. Enacted information was recalled best, followed by visually presented information. Combined effects of modality and golf expertis...
