How well can the theory of planned behavior account for occupational intentions?

We tested the capacity of an extended version of the theory of planned behavior (TPB) to account for intentions to work for the UK’s National Health Service (NHS) as a nurse, physiotherapist or radiographer amongst three groups: professionally unqualified (N = 507), in professional training (N = 244), and professionally qualified (N = 227). We found strong support for the three core TPB variables attitude, subjective norm and perceived behavioral control as predictors of behavioral intention, and limited support for two additional variables: moral obligation and identification. There were some differences in the relative importance of TPB variables between groups. We conclude that the TPB has utility for more complex behaviors as well as simpler ones that are more frequently researched. However, more attention should be paid to differences in people’s circumstances, particularly regarding past vocational decisions and behavior, and to obstacles to implementing an intention.     

Using Mental Imagery to Enhance the Effectiveness of Implementation Intentions

Past research shows that forming implementation intentions increases the probability of carrying out goals. The present research proposes that mental imagery can strengthen the effects of implementation intentions on goal achievement. Participants were assigned a mundane goal and were randomly assigned to one of two conditions: implementation intentions only or implementation intentions plus mental imagery. Results support the hypothesis that using mental imagery when forming implementation intentions leads to higher rates of goal achievement.     

A plea for pragmatics

Let intentionalism be the view that what proposition is expressed in context by a sentence containing indexicals depends on the speaker’s intentions. It has recently been argued that intentionalism makes communicative success mysterious and that there are counterexamples to the intentionalist view in the form of cases of mismatch between the intended interpretation and the intuitively correct interpretation. In this paper, I argue that these objections can be met, once we acknowledge that we may distinguish what determines the correct interpretation from the evidence that is available to the audience, as well as from the standards by which we judge whether or not a given interpretation is reasonable. With these distinctions in place, we see that intentionalism does not render communicative success mysterious, and that cases of mismatch between the intended interpretation and the intuitively correct one can easily be accommodated. The distinction is also useful in treating the Humpty Dumpty problem for intentionalism, since it turns out that this can be treated as an extreme special case of mismatch.     

The Social Conditions for Successful Peer Education: A Comparison of Two HIV Prevention Programs Run by Sex Workers in India and South Africa

Peer education is a community-based intervention being implemented worldwide as an approach to HIV prevention. However, its results are inconsistent, with little consensus on why some projects succeed while others fail. Considering peer education as an ‘intervention-in-context’, we systematically compare the context and the implementation of two peer education interventions run by sex workers, one in India and one in South Africa, which produced contrasting outcomes. In so doing, we aim to identify key factors in the projects’ successes or failures that may inform future peer education efforts. The Indian project’s relative success was facilitated (1) by a more stable and supportive social, material and political context, and (2) by a community development ethos which devoted significant resources to sex workers’ involvement, ownership and empowerment, as opposed to a biomedical approach which marginalised sex workers’ concerns. We conclude with lessons learned and implications for current trends in peer education.     

Effect of delay on children's delay-execute prospective memory performance

To date, little work has been done investigating prospective memory in children, particularly using a delay-execute paradigm. Two experiments were conducted to investigate this issue with children aged 5–11 years. While playing a computer driving game, children's ability to carry out a delayed intention either immediately a target cue appeared or after an additional delay, was assessed. These findings supported the few previous studies in this area by showing that preschool children are able to perform event-based prospective memory tasks. The results also extended these findings by demonstrating the impact of briefly delaying the execution of a retrieved intention, and revealing that there were important improvements in prospective memory performance from early to late childhood. The suggestion is made that executive resources may be responsible for this pattern of performance.     

Predictors of Young Adolescents’ Math Grades and Course Enrollment Intentions: Gender Similarities and Differences

Gender differences and similarities in the relations of key constructs in Eccles and colleagues (Wigfield & Eccles, 2000) model of achievement were examined as predictors of math grades and enrollment intentions for Grade 9 boys (n = 263) and girls (n = 277). A number of gender similarities were found, particularly in the prediction of math grades. There were, however, two gender-specific paths: for girls, a direct path from competence beliefs to enrollment intentions, and for boys, a direct path from prior math grades to enrollment intentions. In addition, for boys, the path from utility value to enrollment intentions was stronger than it was for girls. These differential predictive patterns were found even though girls and boys reported similar levels of math utility and girls had lower math competence beliefs. For girls, competence beliefs were a significant predictor of both intentions and current math grades, which indicates the central role of competence beliefs.     

Unvaxxed and unafraid: Unvaccinated Americans perceive less disease risk than do vaccinated Americans

Is disease risk perception accurately calibrated among the unvaccinated? People shift their attitudes to rationalize their choices, so those who choose to be unvaccinated may be motivated to feel less at risk. In three studies (total N = 1446), we asked Americans how worried they were about catching/spreading influenza and COVID-19 and whether they were vaccinated against those diseases. Unvaccinated participants felt less at risk of catching/spreading the diseases they were unvaccinated against than vaccinated participants. For instance, unvaccinated participants felt ∼24% less at risk of catching/spreading COVID-19 and had ∼28% stronger intention to engage in activities that carried a high risk of COVID-19 transmission (Study 3). Overall, those who choose to be the most vulnerable to disease feel and act the least vulnerable.

Eating Behavior—Choice or Reconstruction of Past Experience? A Randomized Clinical Trial of Changing Eating Intentions of Healthy Adults Through Hypnotic Suggestions

Recent meta-analyses have shown that psychological interventions have a small to medium effect on weight loss. We propose here a different approach to changing eating intentions. According to the Free Will literature, people decide to act before they acknowledge it, and they decide based on the reconstruction of previous experiences. The action can thus be inhibited immediately (max 100 ms) after awareness. We wanted to test if intervention based on this model, using hypnotic suggestions, can effectively change the intentions of eating. This study aims to identify which format of hypnotic suggestion can be more effective in changing eating intentions regarding high-calorie foods. Therefore, 88 healthy adult participants randomized in four groups received one session of hypnotic induction and suggestions or placebo. We measured the eating intentions through a computer task in which participants could choose pictures of low and high caloric food before, during, and after hypnosis. For the within-subject effect, results showed that two types of hypnotic suggestions significantly impacted the intentions of eating on high-calorie foods with large-effect, namely Cognitive Rehearsal (d = 0.81, p < .001) and Memory Substitution (d = 0.82, p < .001). After controlling for pretest ratings, we found a significant between-effect: the Cognitive Rehearsal group differed significantly from the Control in terms of intentions of eating (d = 0.85, p < .05). We conclude that hypnosis with Cognitive Rehearsal suggestions can help to positively impact the intentions of eating.
