This experiment tested the possibility that older adults are less susceptible to semantic illusions because they are more likely to notice contradictions with stored knowledge. Older and young adults encoded stories containing factual inaccuracies; critically, half the participants were instructed to mark any errors they noticed. Older adults reproduced fewer story-errors on a later general kno...

The attachment patterns of younger and older adults were studied using two-dimensional self-report measures of adult attachment. Community-dwelling younger (n = 144, M = 22.5 years, SD = 3.6) and older (n = 106, M = 68.6 years, SD = 8.3) adults completed the Measure of Attachment Qualities (MAQ; Carver, 1997) and the Relationship Style Questionnaire (RSQ; Griffin & Bartholomew, 1994). Although ...

College campuses are particular causes for concern each flu season because of the close and constant proximity of community members. Limited existing research suggests that, like the general population, this subpopulation is undervaccinated, and inaccurate perception of the safety, efficacy, and necessity of the vaccine plays a large part. In this paper, we introduce a simple cost-benefit model...

We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) incur higher costs when subject to a loweredpowered regulation mechanism. The difference is particularly significant (about 7%) for firms in the upper quartile of the efficiency...

How aging affects the utilization of monitoring in the allocation of study time was investigated by having adults learn paired associates during multiple study-test trials. During each trial, a subject paced the presentation of individual items and later judged the likelihood of recalling each item on the upcoming test; after all items had been studied and judged, recall occurred. For both age ...

The ability to detect differences in spatial contrast is crucial to object recognition and identification. This ability is generally examined by measuring the contrast discrimination function. This function represents, for a variety of conditions, the smallest contrast difference required to discriminate otherwise identical patterns. We examined human infants' ability to discriminate patterns o...

The experience of positive affect is essential for healthy functioning and quality of life. Although there is a great deal of research on ways in which people regulate negative states, little is known about the regulation of positive states. In the present study we examined age differences in the types of positive states people strive to experience and the correspondence between their desired a...

Researchers have explored various diagnostic cues to the accuracy of information provided by child eyewitnesses. Previous studies indicated that children's confidence in their reports predicts the relative accuracy of these reports, and that the confidence-accuracy relationship generally improves as children grow older. In this study, we examined the added contribution of response latency to th...

I n this paper, I examine the systemic effects of campaign spending, looking at outcomes at the level of the legislature rather than the individual seat. Using a difference-in-differences design, I show that state-level corporate campaign contribution bans have a large effect on electoral outcomes at the legislature level. A 1 percentage-point increase in the Democratic (or Republican) party’s ...
