LEADER HEURISTICS, POLITICAL KNOWLEDGE AND VOTING IN BRITAIN’S AV REFERENDUM

See on Scoop.itBounded Rationality and Beyond

This paper uses data gathered in a large national survey to investigate the impact of party leader images on voting in Britain’s 2011 national referendum on the Alternative Vote electoral system. Previous studies have found that leader heuristics have significant
effects on voting in major referendums and general elections, and some analysts have argued that these effects are stronger for voters with lower levels of political knowledge.
However, consistent with recent research in experimental conomics, it can be hypothesized that more knowledgeable voters actually rely more heavily on leader heuristics than do less knowledgeable individuals. Using multivariate statistical techniques suitable for analyzing interaction effects in nonlinear models, we show that a
political knowledge index focusing on the electoral system does not have statistically significant effects on referendum voting. However, knowledge of leaders’ positions on AV does interact with their images. The nature of these effects is consistent with the conjecture that more knowledgeable voters place greater emphasis on leader heuristics.

The brains of depressed young adults were compared with normal controls Young adults who have experienced depression have hyper-connected cognitive and emotional networks, a new study finds.Researchers at the University of Illinois at Chicago scanned the brains of 30 adults between the ages of 18 and 23 while they were in a resting state (Jacobs et al., 2014).

The participants had previously experienced depression but were otherwise healthy and not taking any medication.

Their fMRI scans were compared with those of 23 controls who had not experienced serious depression.
