Repeated postevent questioning can lead to elevated levels of eyewitness confidence

Two experiments tested the proposition that postevent questioning can lead to later increases in witness confidence without corresponding changes in witness accuracy. After a staged interruption in a college classroom, participants were questioned about the event 5 times over 5 weeks in Experiment 1 (n=57) and 3 times over 5 days in Experiment 2 (n=79). During the final questioning session, the participant-witnesses consistently reported higher levels of confidence for those items that had been subject to repeated postevent questioning than for those items that were asked for the first time, yet there was no difference in the accuracy of the responses to the two sets of items. Additionally, in all conditions the participant-witnesses were generally overconfident in their responses. These results suggest that repeated postevent questioning can cause eyewitnesses' subsequent confidence estimates to be artificially inflated.     

Performing breastfeeding: embodiment,ethics and the maternal subject

Many feminist sociologists would agree that most breastfeeding research to date has been primarily undertaken from the perspective of medical and public health discourses. While there is evidence of a shift in research on breastfeeding to qualitative studies that focus on the lived experiences of breastfeeding women, this article addresses a number of concerns remaining in the literature surrounding breastfeeding. First, it questions the absence of breastfeeding as a legitimate philosophical topic, and, as a corollary, the invisibility of breastfeeding women as moral or ethical subjects. Second, by drawing on Michel Foucault's account of ethics and Judith Butler's notion of performativity, it is suggested that breastfeeding is best conceptualized as a gendered and embodied ethical practice rather than an aspect of one's being. Finally, this materialist approach to theorizing breastfeeding is discussed in relation to the Lucy Lawless poster that was released in Aotearoa New Zealand to launch World Breastfeeding Week in August 2002.     

Voting May Be Habit-Forming: Evidence from a Randomized Field Experiment

Habit is a frequently mentioned but understudied cause of political action. This article provides the first direct test of the hypothesis that casting a ballot in one election increases one's propensity to go to the polls in the future. A field experiment involving 25,200 registered voters was conducted prior to the November general election of 1998. Subjects were randomly assigned to treatment conditions in which they were urged to vote through direct mail or face-to-face canvassing. Compared to a control group that received no contact, the treatment groups were significantly more likely to vote in 1998. The treatment groups were also significantly more likely to vote in local elections held in November of 1999. After deriving a statistical estimator to isolate the effect of habit, we find that, ceteris paribus, voting in one election substantially increases the likelihood of voting in the future. Indeed, the influence of past voting exceeds the effects of age and education reported in previous studies.     

Party knowledge and candidate knowledge: constituency campaigning and voting and the 1997 British General Election

There has been a recent resurgence of interest in the electoral impact of constituency campaigns in British General Elections. Much is now known about the electoral consequences of local campaigns on parties’ constituency vote shares. Yet more remains to be discovered about the impacts of these local campaigns on voters’ knowledge of parties and candidates. Analysis of data from the 1997 British General Election demonstrates that the local campaign is associated with improved voter knowledge of who is standing for each party in a constituency, which is, in its turn, associated with an increased chance of voting for the party in the election, other things being equal. Campaign efforts at different scales, from the national to the local, have different impacts on voters’ knowledge.
