Social impediments to meat-eaters' adherence to critical calls for a meat-free diet: An experimental test of social norm and message source effects.

Reducing meat consumption is highly effective for reducing personal carbon emissions, yet most people in Western nations still eat meat. We build on recent research highlighting that group boundaries may impede dietary change by (a) promoting pro-meat norms and (b) prohibiting critical calls for a veg* diet (vegetarian and vegan, i.e., meat-free). Past research relied on self-reports and behavioural measures of engagement, leaving open whether these effects extend to food consumption settings and ad-hoc meal choice. We conducted two pre-registered experiments in which meat-eaters read critical calls to adopt a veg* diet, either by a vegan (outgroup) or a meat-eater (ingroup). In Experiment 2, participants moreover read an article either highlighting a veg* or a meat-eating norm. We then assessed actual (Experiment 1) or hypothetical (Experiment 2) meal choice as dependent variables. As predicted, intergroup criticism (i.e., voiced by veg*s) consistently led to message rejection in comparison to the same criticism voiced by meat eaters, but we did not observe effects on meal choice. Norms neither had a main nor interaction effect on self-reports and behaviour. We discuss potential intermediary processes between engagement with and adoption of a vegan diet and derive evidence-based recommendations for constructive communication across group boundaries.

Apologizing for Intergroup Criticism Reduces Rejection of Public Health Officials' Pro-Vaccine Messages.

Compared to other medical experts, public health officials face added scrutiny of their pro-vaccine messages due to distrust of the US federal government. We consider reactions to such critical messages through the lens of conversational norms. Conversational pragmatics suggest that polite communication is essentially cooperative in nature, avoiding criticism of the other or excessive praise of the self. Applied to intergroup communication, this suggests that critical messages from outgroups will be viewed as impolite. Distrusted outgroup sources (such as government officials) are particularly expected to be uncooperative and impolite, increasing message rejection. Importantly, this perspective suggests that apologizing for the norm violation should mitigate these effects. Applying this reasoning to scientific messaging, we demonstrate that a message critical of the under-vaccinated is more likely to be rejected if made by a US federal public health official than by a private medical expert. However, this effect is reduced if the public health official apologizes in advance for violating the norm against criticizing other groups. Improved perceptions of the apologizing source's motives and reduced message threat were associated with higher vaccination intentions. Practical and theoretical implications for intergroup communication are discussed.

Respecting Conversational Norms Improves Reception of Expert Messages Among Unvaccinated Individuals.

The association of medical experts with politically left-leaning cities and states early in the COVID-19 pandemic may have exacerbated vaccine hesitancy in right-leaning states of the US. Criticism from outside experts violates rules of communication between social groups (i.e. an intergroup sensitivity effect), leading to rejection of messages promoting vaccine safety and efficacy. In two studies, we document the effects of shared geographical group membership for medical expert messages promoting vaccination. We also found evidence that satisfying conversational norms against intergroup criticism reduces message rejection. Specifically, an invitation from ingroup political elites for a doctor to speak reduced the negative effects of unshared group identity.

Collective action control: Ubiquitous processes and cultural differences.

Humans have two superpowers: reaching desired end-states (goals) and working together (cooperation). We conceptualize these two capabilities as one: collective action control. We discuss ubiquitous processes and (potential) cultural differences in collective action control in the context of two established frameworks-social identity and norms-as well as an emerging attribution of intent perspective. We illustrate collective action control processes by discussing responses to critical feedback during goal pursuit, as exemplified in research on the rejection of intergroup criticism (Intergroup Sensitivity Effect). Established frameworks did not predict the pattern of current empirical observations. We therefore call for developing the attribution of intent account through systematic theory building and research to identify the ubiquitous and culture-specific processes of collective action control.

What Motivates the Vaccination Rift Effect? Psycho-Linguistic Features of Responses to Calls to Get Vaccinated Differ by Source and Recipient Vaccination Status.

Although vaccination provides substantial protection against COVID, many people reject the vaccine despite the opportunity to receive it. Recent research on potential causes of such vaccine hesitancy showed that those unvaccinated rejected calls to get vaccinated when they stemmed from a vaccinated source (i.e., a vaccination rift). To mend this vaccination rift, it is key to understand the underlying motivations and psychological processes. To this end, we used the voluntary free-text responses comprised of 49,259 words from the original Austrian large-scale data-set (N = 1170) to conduct in-depth psycho-linguistic analyses. These findings indicate that vaccinated message sources elicited longer responses using more words per sentence and simpler language writing more about things rather than themselves or addressing others directly. Contrary to common assumptions, expressed emotions or indicators of cognitive processing did not differ between message source conditions, but vaccinated sources led to more achievement-related expressions. Participant vaccination did not moderate the observed effects but had differential main effects on psycho-linguistic response parameters. We conclude that public vaccination campaigns need to take the vaccination status of the message source and other societal rifts into account to bolster recipients' achievement.

Reaction to poor performers in task groups: A model of pro-group intent.

How do task groups react to poor performers? We integrate attribution theory with individual motivation theories in a novel, parsimonious model that makes nuanced predictions. Our model asserts that group members assess the poor performer's intent to help the group (i.e., pro-group intent) by first considering the poor performer's characteristics suggested by attribution theory: effort and ability. While attribution theorists have mainly assumed that low effort reflects lacking desire to contribute to group goals and that it is infeasible to acquire ability, motivation theories assume individuals set their goals to perform tasks and acquire skills based on both desirability (value) and feasibility (expectancy). As group members may well assume that a poor performer uses these criteria when forming a pro-group intent to contribute to group goals, low effort may also reflect the infeasibility of making the required contributions, and low ability may reflect a low desire to acquire new skills. Therefore, our model of pro-group intent predicts that desirability-feasibility assumptions moderate the effort-ability effect on reactions to poor performers and that evaluations of pro-group intent mediate this effect. Indeed, in five experiments (total N = 1,011), low effort only produced more negative reactions than low ability when a desirability attribution was made for effort, and a feasibility attribution was made for ability. In contrast, reversing these assumptions eliminated the effort-ability effect. This interaction was fully mediated by the performer's perceived pro-group intent. We discuss how our (meta-) intentional perspective informs existing accounts of poor performers, group processes, and motivation science.

Subjective experience, self-efficacy, and motivation of professional football referees during the COVID-19 pandemic.

The present multi-study article investigates the subjective experience of professional football (a.k.a. soccer) referees and players during the COVID-19 pandemic and the so-called ghost games (i.e., games without supporters). Referees from the Austrian Football Association completed questionnaires inquiring about self-efficacy, motivation, and general personal observations and perceptions (e.g., arousal or confidence). In addition, two players and one referee in the Austrian Football Bundesliga were interviewed retrospectively regarding their subjective experience during ghost games and the effects of emotions on behavior and performance using semi-structured, video-taped interviews. Results of the referee survey indicate that the most profound differences between regular games and ghost games lie in the domain of intrinsic motivation and multiple aspects of subjective experience. Specifically, the experience in ghost games compared with regular games was reported by referees as being significantly less motivating, less excited/tense, less emotional, less focused, and overall, more negative, despite being easier to referee and the players behaving more positively. Qualitative analyses of the video-taped interview footage indicated (i) substantial inter-individual variability regarding the extent of the effect of the empty stadiums on the subjective experience of emotions, (ii) consequently, different strategies to regulate emotions and arousal from suboptimal to optimal levels, both before and during competition, and (iii) interactions between reported emotions, arousal, motivation, self-confidence, behavior and performance on the pitch. In addition, non-verbal expressions of emotion were captured using fully automated AI-software that coded facial movements during interviews. The results of this exploratory facial expression analysis revealed varying degrees of arousal and valence in relation to the content of the statements during the interviews, demonstrating the convergent validity of our findings. Our findings contribute to the growing literature on the effects of football games without fans during the COVID-19 pandemic and provide insights into the subjective experience of professional football referees. Concerning referees and players alike, emotions are investigated as potential processes related to home-field advantage and performance in professional football by means of a multi-methods approach. Further, the combination of qualitative and quantitative measures-as well as verbal and non-verbal communication channels-can deepen our understanding of the emotional influence of (missing) spectators on the subjective experience and the behavior of sports professionals is discussed.

Collective action control by goals and plans: applying a self-regulation perspective to group performance.

In celebration of the 125th anniversary of The American Journal of Psychology, this article discusses a seminal publication by Marjorie Shaw (1932) on small group performance in the rational solution of complex problems. We then propose an approach for the effective regulation of group goal striving based on the collective action control perspective. From this perspective, group performance might be hindered by a collective intention-behavior gap: Groups fail to act on their intentions despite being strongly committed to the collective goal, knowing what the necessary actions are, and being capable of performing them. To reduce this gap, we suggest specific if-then plans (implementation intentions) in which groups specify when, where, and how to act toward their collective goal as an easily applicable self-regulation strategy to automate collective action control. Studies in which implementation intentions improved group performance in hidden profile, escalation of commitment, and cooperation task paradigms are reported and discussed.

The vaccination rift effect provides evidence that source vaccination status determines the rejection of calls to get vaccinated.

COVID vaccination protects individuals and helps end the pandemic, but a sizable minority in Western countries rejects the vaccine. Vaccination status should serve as a group membership, critical communication between groups undermines trust, and we accordingly suggest that calls to get vaccinated by vaccinated sources lead to defensive rejection instead of desired behavior change. We term this the vaccination rift effect. A unique collaboration with national print, online and TV news media yielded a large (N = 1170), age-representative sample of Austrian citizens for our fully randomized experiment. Participants exhibited the vaccination rift: They ascribed less constructive motives, d = 0.28, 95% CI [0.17; 0.40], experienced more threat, d = - 0.30, 95% CI [- 0.42; - 0.19], and ascribed worse personality characteristics to vaccinated (vs. unvaccinated) commenters, d = 0.17, 95% CI [0.06; 0.29]. Constructiveness consistently predicted behavioral measures of counterarguing and vaccination planning (indirect effects B = 0.033, SE = 0.013 and B = - 0.056, SE = 0.014). The vaccination rift was substantially stronger among the critical group of unvaccinated participants, ds = |0.39-0.52|, than among those fully vaccinated, ds = |0.08-0.17|. We discuss how to apply these psychological mechanics of the vaccination rift to public campaigns.

Why punish critical outgroup commenters? Social identity, general norms, and retribution.

Group members are more likely to punish criticism of the ingroup when it is provided by outgroup members than by fellow ingroup members. Although this effect could reflect a response to threats to social identity, there may be a general conversational norm proscribing intergroup criticism of any kind. In this case, uninvolved bystanders should also punish individuals who criticize other groups. Past studies of these effects have largely relied on self-reports, making it unclear which theoretical account best explains punishment behaviour. Additionally, the motives underlying punishment of intergroup criticism have not been systematically investigated. Punishment could be intended to inform the commenter that such criticism is inappropriate (i.e., a consequentialist motive) or simply enact revenge (i.e., a retributionist motive). We conducted a registered experiment (N > 800) to examine whether (1) uninvolved bystanders punish intergroup criticism as much as intergroup criticism of their own group, and (2) punishment of intergroup criticism is motivated by consequentialist or retributionist motives. Results revealed more negative reactions to and greater punishment of intergroup criticism compared to intragroup criticism. These effects were actually stronger when the participant was a bystander compared with a member of the targeted group. This finding strongly supports the existence of a conversational norm proscribing intergroup criticism. Protection of social identity resulted in more negative reactions to and punishment of any criticism targeting the ingroup, independent of the source. Finally, punishment extended to situations in which the commenter did not learn of the punishment, consistent with a retributionist motive.

Exploring Higher Education Pathways for Coping With the Threat of COVID-19: Does Parental Academic Background Matter?

First-generation students (FGS) are more likely to feel misplaced and struggle at university than students with university-educated parents (continuous-generation students; CGS). We assumed that the shutdowns during the Coronavirus-pandemic would particularly threaten FGS due to obstructed coping mechanisms. Specifically, FGS may show lower identification with the academic setting and lower perceived fairness of the university system (system justification). We investigated whether FGS and CGS used different defenses to cope with the shutdown threat in a large sample of German-speaking students (N = 848). Using Structural Equation Modeling, we found that for all students, independent of academic parental background, high levels of system justification were associated with perceiving the learning situation as less threatening, better coping with failure, and less helplessness. However, in comparison to CGS, FGS showed small but significant reductions in system justification and relied more on concrete personal relationships with other students as well as their academic identity to cope with the threatening situation. We discuss implications for helping FGS succeed at university.

Strategic Self-Regulation in Groups: Collective Implementation Intentions Help Cooperate When Cooperation Is Called for.

Groups need contributions that are personally costly to their members. Such cooperation is only adaptive when others cooperate as well, as unconditional cooperation may incur high costs to the individual. We argue that individuals can use We-if-then plans (collective implementation intentions, cIIs) to regulate their group-directed behavior strategically, helping them to cooperate selectively with group members in the situation planned for. In line with this prediction, a cII to consider group earnings increased cooperative decisions in a prisoners' dilemma game when playing against another group member but not when playing against a stranger (i.e., non-group member). Moreover, cIIs to cooperate in the prisoners' dilemma game did not increase cooperation in a structurally similar investment game that participants had not planned for. We discuss the role of collective planning in solving social dilemmas.

On the Mechanics of Goal Striving: Experimental Evidence of Coasting and Shifting.

Carver and Scheier's (1990) account of goal striving predicts that unexpectedly fast goal progress leads to reduced effort at that goal (coasting) and to shifting focus toward other goals (shifting). Although these hypotheses are key to this goal-striving account, empirical evidence of coasting and shifting is scarce. Here we demonstrate coasting and shifting in 2 experiments: Participants performed a lexical decision task and were promised a bonus if they delivered a specific number of correct responses (accuracy goal) and a specific number of fast responses (speed goal). After half of the trials, participants received (randomly allocated) feedback on their progress regarding the 2 goals, in which progress toward 1 goal was either above or below the target. In line with hypotheses, better-than-needed progress toward 1 goal led to (a) reduced subsequent progress toward that goal (as reflected in lower goal-related performance; coasting) and (b) a shift of resources toward the alternative goal (as reflected in higher goal-related performance on the alternative goal; shifting). Experiment 1 further demonstrated that positive feedback led to positive affect, and Experiment 2 demonstrated the causal role of affect in coasting and shifting. The implications of the present findings for future research on goal striving are discussed.

Efficiency in Rule- vs. Plan-Based Movements Is Modulated by Action-Mode.

The rule/plan motor cognition (RPMC) paradigm elicits visually indistinguishable motor outputs, resulting from either plan- or rule-based action-selection, using a combination of essentially interchangeable stimuli. Previous implementations of the RPMC paradigm have used pantomimed movements to compare plan- vs. rule-based action-selection. In the present work we attempt to determine the generalizability of previous RPMC findings to real object interaction by use of a grasp-to-rotate task. In the plan task, participants had to use prospective planning to achieve a comfortable post-handle rotation hand posture. The rule task used implementation intentions (if-then rules) leading to the same comfortable end-state. In Experiment A, we compare RPMC performance of 16 healthy participants in pantomime and real object conditions of the experiment, within-subjects. Higher processing efficiency of rule- vs. plan-based action-selection was supported by diffusion model analysis. Results show a significant response-time increase in the pantomime condition compared to the real object condition and a greater response-time advantage of rule-based vs. plan-based actions in the pantomime compared to the real object condition. In Experiment B, 24 healthy participants performed the real object RPMC task in a task switching vs. a blocked condition. Results indicate that plan-based action-selection leads to longer response-times and less efficient information processing than rule-based action-selection in line with previous RPMC findings derived from the pantomime action-mode. Particularly in the task switching mode, responses were faster in the rule compared to the plan task suggesting a modulating influence of cognitive load. Overall, results suggest an advantage of rule-based action-selection over plan-based action-selection; whereby differential mechanisms appear to be involved depending on the action-mode. We propose that cognitive load is a factor that modulates the advantageous effect of implementation intentions in motor cognition on different levels as illustrated by the varying speed advantages and the variation in diffusion parameters per action-mode or condition, respectively.

Planning and Performance in Small Groups: Collective Implementation Intentions Enhance Group Goal Striving.

There are two key motivators to perform well in a group: making a contribution that (a) is crucial for the group (indispensability) and that (b) the other group members recognize (identifiability). We argue that indispensability promotes setting collective ("We") goals whereas identifiability induces individual ("I") goals. Although both goals may enhance performance, they should align with different strategies. Whereas pursuing collective goals should involve more cooperation, pursuing individual goals should involve less cooperation. Two experiments support this reasoning and show that planning out collective goals with collective implementation intentions (cIIs or "We-plans") relies on cooperation but planning out individual goals with individual implementation intentions (IIs or "I-plans") does not. In Experiment 1, three-member groups first formed a collective or an individual goal and then performed a first round of a physical persistence task. Groups then either formed a respective implementation intention (cII or II) or a control plan and then performed a second round of the task. Although groups with cIIs and IIs performed better on a physical persistence task than respective control groups, only cII groups interacted more cooperatively during task performance. To confirm the causal role of these interaction processes, Experiment 2 used the same persistence task and manipulated whether groups could communicate: When communication was hindered, groups with cIIs but not groups with IIs performed worse. Communication thus qualifies as a process making cIIs effective. The present research offers a psychology of action account to small group performance.

Promoting the translation of intentions into action by implementation intentions: behavioral effects and physiological correlates.

The present review addresses the physiological correlates of planning effects on behavior. Although intentions to act qualify as predictors of behavior, accumulated evidence indicates that there is a substantial gap between even strong intentions and subsequent action. One effective strategy to reduce this intention-behavior gap is the formation of implementation intentions that specify when, where, and how to act on a given goal in an if-then format ("If I encounter situation Y, then I will initiate action Z!"). It has been proposed that implementation intentions render the mental representation of the situation highly accessible and establish a strong associative link between the mental representations of the situation and the action. These process assumptions have been examined in behavioral research, and in physiological research, a field that has begun to investigate the temporal dynamics of and brain areas involved in implementation intention effects. In the present review, we first summarize studies on the cognitive processes that are central to the strategic automation of action control by implementation intentions. We then examine studies involving critical samples with impaired self-regulation. Lastly, we review studies that have applied physiological measures such as heart rate, cortisol level, and eye movement, as well as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) studies on the neural correlates of implementation intention effects. In support of the assumed processes, implementation intentions increased goal attainment in studies on cognitive processes and in critical samples, modulated brain waves related to perceptual and decision processes, and generated less activity in brain areas associated with effortful action control. In our discussion, we reflect on the status quo of physiological research on implementation intentions, methodological and conceptual issues, related research, and propose future directions.
