We assessed how age impacted learning who to trust, and the extent to which this type of learning relied on explicit memory. In contrast to prior studies, target faces were neutral without prior reputational information.
Younger and older adults made investment decisions for 36 brokers, who yielded a good, neutral, or bad outcome. Brokers were encountered three times to measure adaptive learning. After the investment task, participants completed a surprise explicit source memory test for brokers.
Although younger and older adults learned to distinguish good and bad brokers from neutral ones, older adults did not learn the brokers' behavior as well as younger adults. In addition, explicit source memory was highly correlated with investment decisions, although less so for good brokers for older than younger adults.
Findings extend prior work by establishing that older adults' impairments in learning who to trust extend to neutral faces, and highlighting the role of explicit memory in investment performance. Future work should vary the task demands to explore the contribution of explicit and implicit processes.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 January 2019.
All research outputs
#24,783,232
of 34,404,538 outputs
Outputs from Journals of Gerontology Series B: Psychological Sciences & Social Sciences
#2,148
of 2,677 outputs
Outputs of similar age
#338,259
of 489,342 outputs
Outputs of similar age from Journals of Gerontology Series B: Psychological Sciences & Social Sciences
#38
of 42 outputs
Altmetric has tracked 34,404,538 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,677 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 23.7. This one is in the 12th percentile – i.e., 12% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 489,342 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 42 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
