    How Do Rituals Affect Cooperation?Ronald Fischer, Rohan Callander, Paul Reddish & Joseph Bulbulia - 2013 - Human Nature 24 (2):115-125.
    Collective rituals have long puzzled anthropologists, yet little is known about how rituals affect participants. Our study investigated the effects of nine naturally occurring rituals on prosociality. We operationalized prosociality as (1) attitudes about fellow ritual participants and (2) decisions in a public goods game. The nine rituals varied in levels of synchrony and levels of sacred attribution. We found that rituals with synchronous body movements were more likely to enhance prosocial attitudes. We also found that rituals judged to be (...)

    Rapid Review and Meta-Meta-Analysis of Self-Guided Interventions to Address Anxiety, Depression, and Stress During COVID-19 Social Distancing.Ronald Fischer, Tiago Bortolini, Johannes Alfons Karl, Marcelo Zilberberg, Kealagh Robinson, André Rabelo, Lucas Gemal, Daniel Wegerhoff, Megan Chrystal & Paulo Mattos - 2020 - Frontiers in Psychology 11:563876.
    We conducted a rapid review and quantitative summary of meta-analyses that have examined interventions which can be used by individuals during quarantine and social distancing to manage anxiety, depression, stress and subjective well-being. A literature search yielded 34 meta-analyses (total number of studies k = 1,390, n = 145,744) that were summarized. Overall, self-guided interventions showed small to medium effects in comparison to control groups. In particular, self-guided therapeutic approaches (including cognitive-behavioral, mindfulness, and acceptance-based interventions), selected positive psychology interventions, and (...)

    Personality, Values, Culture: An Evolutionary Approach.Ronald Fischer - 2017 - Cambridge University Press.
    Humans are complex social beings. To understand human behaviour, an integrated perspective is required - one which considers both what we regularly do and what motivates us. Personality, Values, Culture uses an evolutionary perspective to look at the similarities and differences in personality and values across modern societies. Integrating research on personality and human values into a functional framework that highlights their underlying compatibilities, Fischer describes how personality is shaped by the complex interplay between genes and the environment, both over (...)

    Rituals, Repetitiveness and Cognitive Load.Johannes Alfons Karl & Ronald Fischer - 2018 - Human Nature 29 (4):418-441.
    A central hypothesis to account for the ubiquity of rituals across cultures is their supposed anxiolytic effects: rituals being maintained because they reduce existential anxiety and uncertainty. We aimed to test the anxiolytic effects of rituals by investigating two possible underlying mechanisms for it: cognitive load and repetitive movement. In our pre-registered experiment, 180 undergraduates took part in either a stress or a control condition and were subsequently assigned to either control, cognitive load, undirected movement, a combination of undirected movement (...)

    The Complexities of “Minding the Gap”: Perceived Discrepancies Between Values and Behavior Affect Well-Being.Megan Chrystal, Johannes A. Karl & Ronald Fischer - 2019 - Frontiers in Psychology 10.
    Research on self-determination theory and clinical models such as acceptance and commitment therapy has shown that behaving in line with our values is key to maintaining healthy well-being. Combining work on values and experimental studies on moral hypocrisy and well-being, we experimentally tested how behaving incongruently with values affects well-being. We hypothesized that discrepancies between how one thinks one should have behaved and how one reported one did behave would be more detrimental to well-being when the behaviors were value-expressive and (...)

    Improving climato-economic theorizing at the individual level.Ronald Fischer - 2013 - Behavioral and Brain Sciences 36 (5):488-489.
    Using representative data from 55 nations, I show that individual level wealth interacts with climate in predicting individual happiness but not postmaterialism values. I propose that more research is needed to identify (a) the specific mechanisms of how wealth buffers climatic demands at the individual level and (b) the neurocognitive and physiological reactions of individuals situated in different ecological niches.

    Opportunities and Challenges of Extracting Values in Autobiographical Narratives.Ronald Fischer, Johannes Karl, Velichko Fetvadjiev, Adam Grener & Markus Luczak-Roesch - 2022 - Frontiers in Psychology 13.
    We report three studies in which we applied a value dictionary to narratives. Our objective was to test a theory-driven value dictionary for extracting valuable information from autobiographical and narrative texts. In Studies 1 and 2, participants wrote short autobiographical narratives and in Study 3, participants wrote narratives based on ambiguous stimuli. Participants in all three studies also completed the Portrait Value Questionnaire as a self-report measure of values. Overall, our results demonstrate that it is possible to extract value-relevant information (...)

    Unpackaging cultural variability in behavioral phenotypes.Ronald Fischer - 2022 - Behavioral and Brain Sciences 45:e160.
    We need better understanding of functional differences of behavioral phenotypes across cultures because cultural evolution (e.g., temporal changes in innovation within populations) is less important than culturally molded phenotypes (e.g., differences across populations) for understanding gene effects. Furthermore, changes in one behavioral domain likely have complex downstream effects in other domains, requiring careful parsing of phenotypic variability and functions.

    Testing the Effectiveness of the Health Belief Model in Predicting Preventive Behavior During the COVID-19 Pandemic: The Case of Romania and Italy.Johannes Alfons Karl, Ronald Fischer, Elena Druică, Fabio Musso & Anastasia Stan - 2022 - Frontiers in Psychology 12.
    We use a cultural psychology approach to examine the relevance of the Health Belief Model for predicting a variety of behaviors that had been recommended by health officials during the initial stages of the COVID-19 lockdown for containing the spread of the virus and not overburdening the health system in Europe. Our study is grounded in the assumption that health behavior is activated based on locally relevant perceptions of threats, susceptibility and benefits in engaging in protective behavior, which requires careful (...)
