Distinguishing four types of Person × Situation interactions: An integrative framework and empirical examination.

People differ in their reaction to situations, resulting in Person × Situation interactions. These interactions have been emphasized by many theoretical accounts of personality. Nevertheless, empirical progress on Person × Situation interactions has been slow. This is in part attributable to an insufficient distinction of person and situation variables and of different types of interaction effects. We propose a framework distinguishing four nested types of interaction effects varying in specificity: (a) P × S: broad Person × Situation interaction variance, (b) P × Sspec: between-person differences in situation variable-outcome associations, (c) Pspec × S: between-situation differences in person variable-outcome associations, and (d) Pspec × Sspec: specific Person Variable × Situation Variable interactions. We conducted two large online studies (N = 622 and N = 818) with standardized situation stimuli (N = 62 pictures and N = 62 first-person perspective videos) and assessed Big Five traits, DIAMONDS situation characteristics, and Big Five states. Using preregistered multilevel models, we systematically quantified the different interaction types. We found (a) large Person × Situation interaction variance in personality states, (b) sizable individual differences in situation characteristic-state contingencies, (c) consistent but smaller between-situation differences in trait-state associations, and (d) some significant but (very) small Personality Trait × Situation Characteristic interactions. Our findings highlight Person × Situation interactions as potentially important predictors of psychological states, although the explanation of these interactions through specific person variables remains difficult. Individual differences in the reaction to situations should be incorporated into our models of personality. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Narcissistic status pursuit in everyday social life: A within-person process approach to the behavioral and emotional dynamics of narcissism.

Status pursuit has been emphasized as a key motivational factor underlying narcissism, but research has just begun to unravel the processes by which more narcissistic individuals pursue status in their everyday social interactions. In this article, we combine process models of narcissistic status pursuit with three-factor models of narcissism to test whether different aspects of narcissism (i.e., agentic, antagonistic, and neurotic narcissism) can be characterized by stronger reactivity to different kinds of status perceptions (i.e., the perceived assignment of status, attack on status, and neglect of status). Using data from two experience sampling studies, one involving college students (Nparticipants = 285; Nobservations = 18,036) and one in the general population (Nparticipants = 1,177; Nobservations = 36,074), we first found that the perceived assignment of status, attack on status, and neglect of status were related to status-relevant behaviors (i.e., expressive, combative, and avoidant behaviors) and emotions (e.g., pride, anger, and shame) within persons on average. Next, we found that both mean levels of perceptual, behavioral, and emotional states and status contingencies (i.e., the within-person relationships of status perceptions with behavioral and emotional states) varied considerably across individuals and that these individual differences were reliable and stable across time. Last, we found some associations between trait levels of agentic, antagonistic, and neurotic narcissism and individual differences in mean levels as well as status-emotion contingencies. Our findings emphasize the multifaceted and status-driven nature of narcissism and support the use of theoretically derived contingencies as more dynamic aspects of personality.

Who benefits from which activity? On the relations between personality traits, leisure activities, and well-being.

Leisure activities have been emphasized as an important predictor of well-being. However, little research has examined the effects of leisure activity enactment on well-being over time. Moreover, it is unknown which activities are most beneficial for whom. We integrate diverse theoretical accounts of person-environment relations and propose a generic Personality-Activity-Well-Being (PAW) framework, which highlights different relations between personality traits, activities, and well-being. To investigate these relations, we used 11 annual waves from the Longitudinal Internet Studies for the Social Sciences (LISS) panel (total N = 12,703 participants, N = 59,108 assessments), which included measures of the Big Five personality traits, 15 different leisure activities, and affective well-being and life satisfaction. Our preregistered multilevel models revealed three sets of findings. First, we observed on average small expected between-person associations between leisure activities and well-being (e.g., higher average levels of holidays, evening socializing, talking to close others, exercise, and cultural activities were associated with higher well-being). Annual within-person fluctuations in several leisure activities also predicted well-being in expected ways, but effect sizes were very small and varied strongly across participants. Second, personality traits were related to leisure activities in hypothesized ways, yielding on average small but also some moderate and large correlations. Third, Personality Trait × Leisure Activity interactions were only evident on the between-person level, very small in size, and in the opposite direction of our expectations. Personality traits did not moderate well-being benefits from leisure within persons. We discuss the implications of our findings and sketch an agenda for future work.

Individual differences in contingencies between situation characteristics and personality states.

Contingencies between situational variables and psychological states have been proposed as key individual difference variables by many theoretical approaches to personality. Despite their relevance, the basic properties, nomological correlates, and factor structure of individual differences in contingencies have not been examined so far. We address these fundamental questions in five studies with overall N = 952 participants and N = 32,052 unique assessments. Individual differences in situation characteristic-state contingencies (SCSCs) between DIAMONDS situation characteristics and Big Five personality states were examined in everyday life. SCSCs showed substantial variation across participants, and individual differences in them were moderately reliable (average meta-analytic reliability = .47) and short-term stable (average meta-analytic latent stability = .43). They were weakly and inconsistently related to average personality states, self-reported personality traits, subjective happiness, and sociodemographic variables across studies. However, there were meaningful intercorrelations among SCSCs that could be described by four factors: contingencies involving (1) positive states and situational problems, (2) positive states and situational rewards, (3) thinking/work and requirements of thinking/work, and (4) neurotic states. Overall, our findings support the notion of SCSCs as potentially important individual difference variables, and we sketch future lines of research on contingencies.

Examining the reliability and validity of two versions of the Effort-Expenditure for Rewards Task (EEfRT).

The Effort-Expenditure for Rewards Task (EEfRT) has gained validity evidence from several studies. However, various modifications have been applied to the original version, which have never been compared systematically. In Study 1, we tested 120 healthy participants to directly compare two versions of the EEfRT. In Study 2, we tested a larger sample of 394 healthy participants to further examine the original EEfRT. We replicated the split-half reliability of both task versions. However, self-reported personality traits (e.g., trait BAS) correlated with only some task performance parameters in Study 1, which did not replicate for the original EEfRT in Study 2. Our results indicate complex and sometimes inconsistent relations between different personality traits, task properties, and reward attributes.

The dynamics, processes, mechanisms, and functioning of personality: An overview of the field.

Personality psychology has long focused on structural trait models, but it can also offer a rich understanding of the dynamics, processes, mechanisms, and functioning of individual differences or entire persons. The field of personality dynamics, which works towards such an understanding, has experienced a renaissance in the last two decades. This review article seeks to act as a primer of that field. It covers its historical roots, summarizes current research strands - along with their theoretical backbones and methodologies - in an accessible way, and sketches some considerations for the future. In doing so, we introduce relevant concepts, give an overview of different topics and phenomena subsumed under the broad umbrella term 'dynamics', and highlight the interdisciplinarity as well as applied relevance of the field. We hope this article can serve as a useful overview for scholars within and outside of personality psychology who are interested in the dynamic nature of human behaviour and experience.

The situation during the COVID-19 pandemic: A snapshot in Germany.

During government-implemented restrictions in the wake of the COVID-19 pandemic, people's everyday lives changed profoundly. However, there is to date little research chronicling how people perceived their changed everyday lives and which consequences this had. In a two-wave study, we examined the psychological characteristics of people's situations and their correlates during shutdown in a large German sample (NT1 = 1,353; NT2 = 446). First, we compared characteristics during government-issued restrictions with retrospective accounts from before and with a follow-up assessment 6 to 7 months later when many restrictions had been lifted. We found that mean levels were lower and variances were higher for most characteristics during the shutdown. Second, the experience of certain situation characteristics was associated in meaningful and theoretically expected ways with people's traits, appraisals of the COVID-19 crisis, and subjective well-being. Lastly, situation characteristics often substantially explained the associations of traits with appraisals and well-being. Our findings highlight the importance of considering perceived situations as these contribute to people's functioning during crises.

A low dosage of the dopamine D2-receptor antagonist sulpiride affects effort allocation for reward regardless of trait extraversion.

Dopamine (DA) is known to be involved in various aspects of reward processing and goal-directed behavior. The present preregistered study aims at directly accessing the causal influence of DA activity on reward motivation in humans, while also accounting for trait extraversion. Therefore, we examined the effect of a single dose of the DA D2 receptor antagonist sulpiride (200 mg) on effort allocation in a modified version of the Effort-Expenditure for Reward Task (EEfRT). Based on its presumably DA increasing action, we expected the low dose of sulpiride to increase participants' willingness to allocate effort during the modified EEfRT relative to placebo, especially in trials with low probability of reward attainment. Further, we expected a moderating effect of trait extraversion on the effects of sulpiride. Two hundred and three healthy male participants were tested in a randomized, double-blind between-subjects design. Contrary to our expectations, sulpiride reduced the average number of clicks within the modified EEfRT and did not interact with reward attributes, suggesting a more global and not reward-specific effect of sulpiride. Furthermore, trait extraversion did not moderate the effect of sulpiride. Our results provide initial support for the validity of the modified version of the EEfRT, suggesting a possible inhibiting effect of a low dose of sulpiride on approach motivation regardless of trait extraversion. However, given the mixed pattern of findings and the possible confounding role of motoric abilities, further studies examining these effects are clearly warranted.

Left frontal anodal tDCS increases approach motivation depending on reward attributes.

BACKGROUND: A growing body of literature indicates a correlation between asymmetrical activity of frontal brain sites and approach vs. withdrawal motivation. Yet the causal status of this relationship is presently unclear. Here we examined the effect of anodal tDCS applied over the left dorsolateral prefrontal cortex (dlPFC) on approach motivation, operationalized as effort allocation during the Effort-Expenditure for Reward Task (EEfRT). HYPOTHESIS: We expected left frontal anodal transcranial direct current simulation (tDCS) to increase participants' willingness to allocate more effort during the EEfRT. Based on previous research, we expected this effect to be strongest on trials with low probability of reward attainment. METHODS: 60 right-handed neurologically and psychologically healthy participants (63% female) aged 18-35 were tested in a counterbalanced within-subject design. Participants were invited to our lab twice to complete two 15-min blocks of the EEfRT on each study day, randomly assigned to either an anodal tDCS or a SHAM condition. RESULTS: No main effect of stimulation condition was found, however the interactions of stimulation condition and both probability of reward attainment and reward magnitude reached significance. These interactions indicated that left frontal anodal tDCS specifically increased the percentage of hard task choices (HTC) in trials with low probability of reward attainment and in trials with high reward magnitude. DISCUSSION: The observation of an increasing effect of left frontal anodal tDCS on effort expenditure for reward as indicated by HTC supports the idea of a causal relationship between asymmetric activity of frontal brain sites and approach motivation and hints at moderating effects of task-features on the effects of tDCS.
