Enhancing current explanations of domestic violence exposure effects on child cognitive and behavioral functioning was the
purpose of this investigation. Participants were 31 domestic violence exposed and 31 non-exposed children ages 3 to 5 years
and their single-parent household mothers. Child-mother pairs were matched for child’s age, gender, and ethnicity, mother’s
age and education, and annual family income. Child cognitive and behavioral functioning was assessed via psychological assessment
and parent report. The presence of mental health difficulties in mothers was assessed using self-report and clinician-administered
instruments. Exposed children showed lower verbal functioning and higher internalizing behaviors than did their non-exposed
peers. Exposed mothers displayed greater psychological difficulties than did their counterparts. 相似文献

According to numerous studies, the election‐year economy influences presidential election results far more than cumulative growth throughout the term. Here we describe a series of surveys and experiments that point to an intriguing explanation for this pattern that runs contrary to standard political science explanations, but one that accords with a large psychological literature. Voters, we find, actually intend to judge presidents on cumulative growth. However, since that characteristic is not readily available to them, voters inadvertently substitute election‐year performance because it is more easily accessible. This “end‐heuristic” explanation for voters’ election‐year emphasis reflects a general tendency for people to simplify retrospective assessments by substituting conditions at the end for the whole. The end‐heuristic explanation also suggests a remedy, a way to align voters’ actions with their intentions. Providing people with the attribute they are seeking—cumulative growth—eliminates the election‐year emphasis. 相似文献

ABSTRACTHistorians of terrorism note that modern terrorists rely almost exclusively on two weapon types: the gun and the bomb. However, the comparative use of these weapons differs from one terrorist group to the next. We exploit this variation to examine how the tactical decisions of terrorists respond to both strategic aspirations and resource constraints. We argue that a group’s goals (a strategic consideration) and size (a resource constraint) provide a parsimonious explanation for weapon selection. Because firearms inherently expose the shooter to higher risk, are more precise, and must be used if a group aspires to maintain social order, they are unlikely to be used by groups with limited recruits in a campaign of violence. We test this theory using data on over 350 terrorist organizations. Our analysis shows that strategic considerations and resource constraints both impact tactical choices, although groups with the most expansive goals, those which transcend national borders, as well as militias, are two interesting exceptions to our theory. Our research has implications for the use of disaggregated tactical data and in furthering our understanding of the rationality of terrorism. 相似文献
