Monetary incentives are increasingly used to help motivate survey participation. This article summarizes several theories underlying the use of incentives and briefly reviews research demonstrating their intended and unintended effects on response rates, sample composition, response bias, and response quality. It also considers the evidence for the effectiveness of incentives in reducing nonres...

In previous work we presented a computational framework that allows a robot or agent to reason about whether it should trust an interactive partner or whether the interactive partner trusts the robot (Wagner & Arkin, 2011). This article examines the use of this framework in a well-known situation for examining trust--the Investor-Trustee game (King-Casas, Tomlin, Anen, Camerer, Quartz, & Montag...

Genes that suppress recombination when heterozygous have been found distributed as a polymorphism in wild and laboratory populations of Neurospora crassa. Three alleles, ssE, ssS and ssC, are associated, respectively, with th the three wild types Emerson, St. Lawrence 74A and Costa Rica A. It is proposed that ss (synaptic sequence) genes modulate recombination by determining the pairing closene...

OBJECTIVES To determine whether criminals go to the hospital when they are shot. Such information is needed to check on the accuracy of using hospital emergency room data to estimate non-fatal gunshot wounds. SETTING Five jails across the US. METHODS A survey of inmates being booked into jail, administered by in-house health care staff. RESULTS Over 90% of over 300 criminals who had been ...

Counterintuitively, Y. Kareev, I. Lieberman, and M. Lev (1997) found that a lower short-term memory capacity benefits performance on a correlation detection task. They assumed that people with low short-term memory capacity (low spans) perceived the correlations as more extreme because they relied on smaller samples, which are known to exaggerate correlations. The authors consider, as an altern...
