Veterinarians are increasingly looked to for guidance on matters relating to animal welfare, yet little is known about US veterinary students’ attitudes and beliefs about animals. In 2019, we surveyed all first-year veterinary students at a major US veterinary college (n = 123) before and after taking a required one-credit introductory animal welfare course. Attitudes were measured using the Pests, Pets and Profit (PPP) scale and belief in animal mind (BAM) was measured using an ad hoc measure adapted from previous work. Pre- and post-course comparisons indicated the introductory animal welfare course had no immediate effect on veterinary students’ attitudes or BAM. Veterinary students’ attitudes were most positive for animals considered pets, followed by pests and those used for profit. Students believed most species possess a wide variety of mental capacities, including many secondary emotions often considered uniquely human (eg guilt, embarrassment, jealousy). Sociodemographic variables consistently associated with more positive attitudes towards animals were: female gender, vegetarianism and liberal political ideology. Preferring a career involving large or food animal practice was consistently associated with less positive attitudes towards animals. Belief in animal mind explained 3% of the variation in attitude scores, whereas sociodemographic variables explained 49% of variation in attitude scores. Female gender, vegetarianism and preferring small (vs large or food animal practice) were all associated with greater BAM scores. Understanding veterinary student attitudes towards animals and beliefs about the mental capacities of animals is important when evaluating a veterinarian's ability to adhere to their oath.

Political identification is the basis of enduring conflict, suggesting thatpolitical attitudes are difficult to change. Here we show that in the 2016 U.S.Presidential Election, political identities underwent modification in responseto salient political events. We investigate these dynamics in detail bycollecting data at periodic intervals from mid-June 2016 through the generalelection (N = 3,958). We operationalize identification using prosocial giving inDictator Games played between supporters of competing primary candidatesrecruited from Amazon Mechanical Turk. The observed dynamics differed acrosspolitical parties. In-group bias among Democrats remained high until theDemocratic National Convention, disappeared shortly thereafter, and thenreturned during the final stage of the election. Bias among Republicans wasgenerally high until the final days of the election. The late resurgence of biasamong Democrats was not reflected in voting intentions, but may have presagedthe Democratic election loss.

Discussions around declining trust in the US media can be vague about its effects. One classic answer comes from the persuasion literature, in which source credibility plays a key role. However, existing research almost universally takes credibility as a given. To overcome the potentially severe confounding that can result from this, we create a hypothetical news outlet and manipulate to what extent it is portrayed as credible. We then randomly assign subjects to read op-eds attributed to the source. Our credibility treatments are strong, increasing trust in our mock source until up to 10 days later. We find some evidence that the resulting higher perceived credibility boosts the persuasiveness of arguments about more partisan topics (but not for a less politicized issue). Though our findings are mixed, we argue that this experimental approach can fruitfully enhance our understanding of the interplay between source trust and opinion change over sustained periods.

Social movement research indicates that mobilization can effect change in political attitudes, yet few works have systematically tested the effect of protests on public opinion. This article uses survey and protest event data to assess the spatial and temporal effect of mobilizations on political attitudes Chile. It combines the 2008, 2010, and 2012 LAPOP surveys and a dataset of college student protest events, mapping respondents and protests at the municipal level using Geographic Information Systems (GIS). Using regression analyses, it finds that proximity to college student protests has a significant effect on various political attitudes. The effect, however, tends to be substantively larger on “weak” attitudes and smaller on “strong” ones. The results highlight the importance of mobilizations in shaping individual political attitudes and the role that social movements play in the policy-making process.

Our main purpose was to explore hypotheses derived from the Identification of Action Theory in a particular situation that is, a dissonant situation. Thus, we varied the identification (low versus high-level) of a problematic behavior (to stop speaking for 24 hours) in the forced compliance paradigm. Two modes of dissonance reduction were presented: cognitive rationalization (classical attitude-change) and behavioral rationalization (target behavior: to stop speaking for 48 hours). As predicted, the results showed that high-level identity of action leads to cognitive rationalization whereas low-level identity leads to behavioural rationalization. Thus, participants identifying the problematic behavior at a low-level were more inclined to accept the target behavior, compared with participants identifying their problematic behavior at a higher-level. These results are of particular interest for understanding the extent to which the understanding of the discrepant act interferes with the cognitive processes of dissonance reduction.

It is a perennial issue in the public and the scientific debate whether increased pressures to reform due to the financial crisis or population ageing erode welfare state support. Surprisingly, our knowledge of how individuals change their attitudes in hard times is still limited – both theoretically and empirically. We rely on newly available data from a survey experiment in a representative German online survey and exogenously manipulate the perceived pressure to reform (due to an ageing society). We show that people indeed change their reform preferences when faced with an ageing society: the strong opposition to increasing the retirement age decreases. Further analyses reveal that not all groups within society react to increased reform pressures in the same way: political knowledge but also political partisanship do moderate the strength and the direction of the attitude change.

In an experimental evaluation of a “friendly visitor” type of program in which adolescents visited senior citizens, it was found that general attitudes toward elderly people (measured by the Semantic Differential developed by Rosencranz and McNevin) improved following weekly contact with specific elderly persons. One of the weaknesses in research on this type of intervention has been the assumption that the quality of the contact was uniform, and the impact of quality was rarely assessed. In the present study, the perceived quality of the experience was found to have a significant impact on improving attitudes. Programs such as the one evaluated here can, therefore, have two outcomes: the provision of service to elderly individuals and the change of negative attitudes toward elderly people.

A qualitative study was conducted with a subset of a Community Supported Agriculture (CSA) membership base in Wisconsin, USA to examine attitude and behavior change associated with membership. Changes that were examined included: modified eating or cooking habits, increased consideration of food seasonality and associated consumer preferences for seasonal products, and an enhanced appreciation for farming. Although this study investigated ‘spillover’ attitude or behavior changes (e.g. reduced driving or increased use of environmentally friendly cleaning products), none were observed. This study indicates that attitude and behavior changes are generated by the structural elements of CSA including exposure to the farm, interactions with the farmer, and the constraints imposed by a pre-selected bundle of vegetables. There was no indication that changes occur due to the development and enforcement of social norms within the CSA membership base. Community, in the context of this CSA, is expressed primarily as a conceptual community of interest. Our results suggest that demonstrated attitude and behavior change increases the likelihood that a consumer will renew their CSA membership.
