Transitions Into and Out of Voluntary Work Over the Life Course: What is the Effect of Major Life Events?

The aim of the current study is to investigate which major life events are associated with transitions into and out of volunteering over the life course and, especially, why these associations exist. Social Production Function theory is used to derive hypotheses, which are tested using longitudinal data (adult subsample) from Lifelines. Associations between major life events and (a) volunteer take-up, nonvolunteer sample ( N = 59,773) and (b) volunteer cessation, volunteer sample ( N = 32,143) are studied by applying Linear Probability Modeling. Results show clear associations between specific major life events and starting and quitting volunteering. The influence on the latter is stronger than on the former. Most findings are in line with our theory-based expectations indicating that (a) voluntary work contributes especially to the fulfillment of the needs for status, stimulation, and behavioral confirmation and (2) life events causing losses (gains) in these needs are associated with a higher likelihood to take-up (quit) volunteering.

Social Needs and Happiness: A Life Course Perspective

Introduction. Both the fulfilment of affection, status, and behavioral confirmation needs and their role in happiness may differ along the adult lifespan. Aims. We examined age-graded differences in (a) the fulfilment of the need for affection, status, and behavioral confirmation, (b) disharmonious profiles of need fulfillment (e.g., high affection but low status), and (c) the associations between these needs and happiness. Methods. Data from 11,406 Dutch respondents (age range 18-87 (M=44.82, SD=14.62), 67% female) were collected via hoegekis.nl and categorized over six age groups (early, young, middle-aged and late adults, young-old and oldest-old). Age-graded differences in social need fulfilment and their link to happiness were examined using regression analyses. Need fulfillment profiles were identified with LCA cluster analyses. Results. Age-graded differences in social need fulfilment were virtually absent (Cohen’s d=0.20 or smaller) and their link with happiness was stable across the age groups. Social need fulfilment profiles were harmonious as people reported either low, middle, or high need fulfilment in general, irrespective of age. Conclusion. The idea that different social needs are more important in different phases of adult life received only weak support in our data. No strategic investment in specific social needs was observed (no substitution-effects). People typically differed in their capacities to fulfil their affection, status, and behavioral confirmation needs in general, regardless of age. The implications of these results for the social production function theory of wellbeing and socioemotional selectivity theory are outlined in the discussion.

Stuck in Place? A Field Experiment on the Effects of Reputational Information on Student Evaluations

Studies suggest that students’ prior performance can shape subsequent teacher evaluations, but the magnitude of reputational effects and their implications for educational inequality remain unclear. Existing scholarship presents two major perspectives that exist in tension: do teachers primarily use reputational information as a temporary signal that is subsequently updated in response to actual student performance? Or do teachers primarily use reputational information as a filter that biases perception of subsequent evidence, thus crystallizing student reputations and keeping previously poor-performing students stuck in place? In a field experiment, we recruited a random sample of 832 junior high school teachers from the second-most populous province of China to grade a sequence of four essays written by the same student, and we randomly assign both the academic reputation of the student and the quality of the essays produced. We find that (1) reputational information influences how teachers grade, (2) teachers rely on negative information more heavily than positive information, and (3) negative reputations are crystallized by a single behavioral confirmation. These results suggest that students can escape their prior reputations, but to do so, they must contradict them immediately, with a single confirmation sufficient to crystallize a negative reputation.

A Behavioral Confirmation and Reduction of the Natural versus Synthetic Drug Bias

Research reveals a biased preference for natural v. synthetic drugs; however, this research is based on self-report and has not examined ways to reduce the bias. We examined these issues in 5 studies involving 1125 participants. In a pilot study ( N = 110), participants rated the term natural to be more positive than the term synthetic, which reveals a default natural-is-better belief. In studies 1 ( N = 109) and 2 ( N = 100), after a supposed personality study, participants were offered a thank you “gift” of a natural or synthetic pain reliever. Approximately 86% (study 1) and 93% (study 2) of participants chose the natural v. synthetic pain reliever, which provides a behavioral choice confirmation of the natural drug bias. In studies 3 ( N = 350) and 4 ( N = 356), participants were randomly assigned to a control or experimental condition and were asked to consider a scenario in which they had a medical issue requiring a natural v. synthetic drug. The experimental condition included a stronger (study 3) or weaker (study 4) rational appeal about the natural drug bias and a statement suggesting that natural and synthetic drugs can be good or bad depending on the context. In both studies, the natural bias was reduced in the experimental condition, and perceived safety and effectiveness mediated this effect. Overall, these data indicate a bias for natural over synthetic drugs in preferences and behavioral choices, which might be reduced with a rational appeal.

Impressions Based on a Portrait Predict, 1-Month Later, Impressions Following a Live Interaction

When it comes to person perception, does one “judge a book by its cover?” Perceivers made judgments of liking, and of personality, based on a photograph of an unknown other, and at least 1 month later, made judgments following a face-to-face interaction with the same person. Photograph-based liking judgments predicted interaction-based liking judgments, and, to a lesser extent, photograph-based personality judgments predicted interaction-based personality judgments (except for extraversion). Consistency in liking judgments (1) partly reflected behavioral confirmation (i.e., perceivers with favorable photograph-based judgments behaved more warmly toward the target during the live interaction, which elicited greater target warmth); (2) explained, at least in part, consistency in personality judgments (reflecting a halo effect); and (3) remained robust even after controlling for perceiver effects, target effects, and perceived attractiveness. These findings support the view that even after having “read a book,” one still, to some extent, judges it by its “cover.”
