Using Dynamic Panel Models to Study Age‐related Differences and Time‐related Changes in Personality

Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology     

Sleep variability and fatigue in adolescents: Associations with school‐related features

This study aims to evaluate the influences of sleep duration and sleep variability (SleepV), upon adolescents' school‐related situations. The Health Behaviour in School‐Aged Children (HBSC) survey is based on a self‐completed questionnaire. The participants were 3164 pupils (53.7% girls), attending the 8th and 10th grades, 14.9 years old, and were inquired about subjective sleep duration during the week and weekends, SleepV, fatigue, difficulties in sleep initiation, school achievement, feelings towards schools, pressure with school work and skipping classes. Multiple regression models used, as dependent variables: (a) school achievement, (b) disliking school, (c) pressure with school work and (d) skipping classes, using as independent variables, each of the remaining school‐related variables, fatigue, total sleep duration and difficulties in sleep initiation. The average sleep duration in the week and during weekdays was lower than recommended for these age groups, and almost half of students had high SleepV between weekdays and weekends. A logistic model revealed that the absence of SleepV was associated with lower perception of school work pressure, less frequent skipping classes, more infrequent fatigue and more infrequent difficulties in sleep initiation. Poor sleep quality, SleepV and insufficient sleep duration affected negatively school‐related variables.     

Social problem‐solving skills following childhood traumatic brain injury and its association with self‐regulation and social and behavioural functioning

This study examines social problem‐solving skills following childhood traumatic brain injury (TBI) and its association with self‐regulation, and social and behavioural functioning. Participants included 65 children with moderate to severe TBI and 65 children without TBI, all between 6 and 11 years of age. Social problem‐solving, self‐regulation, and social and behavioural functioning were assessed 2–5 years following injury. Children were administered a newly developed semi‐structured task to assess their solutions to hypothetical situations involving social problems or dilemmas. When compared with uninjured children, those with TBI suggested avoidant and aggressive solutions more often and assertive solutions less often in response to the hypothetical situations. Children's self‐regulatory skills, as measured by the Matching Familiar Figures Test (MFFT), Test of Everyday Attention for Children (TEA‐Ch) and the Delay of Gratification Task (DGT), collectively accounted for significant variance in their solutions to social problems, such that better self‐regulation predicted more assertive solutions and fewer aggressive solutions. Assertive solutions were positively related to parent‐ and teacher‐rated social and behavioural outcomes, whereas aggressive solutions were negatively related to the outcomes. The difficulties in social problem‐solving skills demonstrated by children with TBI may help account for their poor social and behavioural functioning.     

Designing Health Communications: Harnessing the Power of Affect,Imagery, and Self‐Regulation

We review recent advances in self‐regulation theory and research, highlighting implications for communication strategies aimed at persuading individuals to adopt health‐protective behaviors. We focus on the role of affect and imagery processes in health persuasion, reviewing research on how fear arousal and imagery influence health information processing and decision‐making. Despite ongoing controversy over the use of fear‐arousing appeals, considerable empirical evidence supports their efficacy. Such threat appeals can backfire, however, if they fail to address key aspects of self‐regulation processes. Research on the cognitive and emotional influences of imagery and other concrete‐perceptual stimuli points to strategies for integrating them into health persuasion efforts. Mental simulation techniques represent another promising avenue for communications aimed at fostering health behavior change. New directions of inquiry include research on appeals that arouse emotions other than fear (e.g., positive emotions), more nuanced applications of fear arousal in communications, and applications for computer‐based and Internet communications.     

Typical and atypical self‐regulation in adolescence: the importance of studying change over time

Researchers, parents, and teachers alike are concerned with the healthy development of self‐regulation, particularly because of its influence on a wide range of academic, economic, social, and health outcomes. However, little is known about how to characterize typical and atypical self‐regulation development, especially among adolescents, a population that is uniquely challenged with competing demands and expectations. The arguments of the present review are twofold: (1) it is critical to use fine‐grained longitudinal data to study change over time in self‐regulatory traits among youth, in order to fully understand typical and atypical self‐regulation; and (2) one compelling way to study the typical and atypical development of self‐regulation is through its intersection with externalizing problems. A thorough examination of the literature reveals that, on average, youth struggle with self‐regulation in adolescence, as evidenced by a decline in self‐regulatory capacities from age 10 to 14 and an improvement in self‐regulatory skills from age 14 to 19. Concomitantly, youth show mean‐level increases in externalizing problems (e.g., delinquency, aggression, alcohol/drug use, school behavioral problems) during adolescence. Further, co‐developmental associations indicate that poor self‐regulation leads adolescents to show greater increases in externalizing problems over time (vulnerability model); the act of engaging in these problematic behaviors leads youth to experience greater decreases in self‐regulation over time (scar model); self‐regulation and externalizing problems are distinct developmental constructs (spectrum model). The implications of studying trait and behavior change over time are highlighted, and future directions in this area of research are discussed.     

Gender differences on laugh‐related traits: A cross‐sectional study

People have different responses to being laughed at, including fear of being laughed at, joy from being laughed at and joy from hearing others laugh. Previous studies have indicated that men have a higher tendency of laughing at others, but there were no gender differences on terms of the other two responses. Socioemotional selectivity theory indicates that individuals pay less attention to negative stimuli as they get older. It is worth investigating whether the gender differences of gelotophobia and gelotophilia occur in certain developmental stages. The present study is a cross‐sectional study, with a sample size of 1247 participants; we collected information regarding laugh‐related traits among participants 11–66 years old, and we particularly focused on the moderation effect of age on gender differences on gelotophobia, gelotophilia and katagelasticism. The results showed that men had a stronger tendency for laughing at others, but there were no significant gender differences on terms of gelotophobia and gelotophilia; age not only moderated the relationship between gender and gelotophobia but also the relationship between gender and katagelasticism. Male adolescents had higher incidences of gelotophobia and katagelasticism than female adolescents, but this finding was not consistent in the middle adulthood sample. The present study found age to be a moderator between gender and laugh‐related traits, and it indicated the influence of age on the fear of being laughed at during early adolescence, but there was no gender difference with respect to katagelasticism in middle adulthood.     

Vigilant Self‐regulation and Costly Punishment in Public Goods Situations

Applying regulatory focus theory to the context of social dilemma situations, the present research demonstrates that individual differences in vigilant, prevention‐focused self‐regulation predict the tendency to invest private resources to punish uncooperative interaction partners (costly punishment), a behaviour that typically has strong positive effects on the collective level of cooperation. Analyses further support the distinctiveness of the vigilance system proposed in regulatory focus theory (prevention focus) in comparison with general defensive inhibitory tendencies (measured with Carver and White's Behavioral Inhibition System scale). Results document that individual differences in prevention‐focused self‐regulation but not differences in general defensive inhibitory tendencies are positively related to costly punishment. In sum, the findings indicate that vigilant, prevention‐focused self‐regulation plays a crucial role in the context of sanctions that enforce cooperation.

Self‐determination theory,social media and charitable causes: An in‐depth analysis of autonomous motivation

Using the framework of the self‐determination theory continuum, we investigated the influence of the distinct autonomous and controlled motivational regulations for engaging participants in online and offline support of charitable events for the causes of breast cancer and homeless youth. Participants were exposed online to Facebook event pages appealing to helping others. When the often omitted integrated autonomous regulation was included in the model, it was the strongest predictor of supportive intentions. Without integrated regulation in the model, we would have overestimated the relatively minor influence of controlled introjected regulation. Furthermore, rather than one overall measure of autonomous intrinsic regulation, we assessed the differential influences of three separate dimensions (to experience stimulation, to learn and to accomplish). Intrinsic motivation to experience stimulation had a unique influence on online and offline supportive intentions. Such was not the case for the dimensions of to learn or to accomplish. Follow‐up meditation analyses of self‐reported behaviours confirmed that autonomous integrated and intrinsic to experience stimulation regulations led to stronger intentions to support online behaviours, which, in turn, increased the likelihood of actual online engagement. The findings in a social media context highlight the importance of analysing distinct regulatory styles within the self‐determination theory continuum. Copyright © 2015 John Wiley & Sons, Ltd.     

When being a girl matters less: Accessibility of gender‐related self‐knowledge in single‐sex and coeducational classes and its impact on students' physics‐related self‐concept of ability

Background . Establishing or preserving single‐sex schooling has been widely discussed as a way of bringing more girls into the natural sciences. Aims . We test the assumption that the beneficial effects of single‐sex education on girls' self‐concept of ability in masculine subjects such as physics are due to the lower accessibility of gender‐related self‐knowledge in single‐sex classes. Sample . N = 401 eighth‐graders (mean age 14.0 years) from coeducational comprehensive schools. Methods . Random assignment of students to single‐sex vs. coeducational physics classes throughout the eighth grade. At the end of the year, students' physics‐related self‐concept of ability was measured using a questionnaire. In a subsample of N = 134 students, the accessibility of gender‐related self‐knowledge during physics classes was assessed by measuring latencies and endorsement of sex‐typed trait adjectives. Results . Girls from single‐sex physics classes reported a better physics‐related self‐concept of ability than girls from coeducational classes, while boys' self‐concept of ability did not vary according to class composition. For both boys and girls, gender‐related self‐knowledge was less accessible in single‐sex classes than in mixed‐sex classes. To the extent that girls' feminine self‐knowledge was relatively less accessible than their masculine self‐knowledge, their physics‐related self‐concept of ability improved at the end of the school year. Conclusions . By revealing the importance of the differential accessibility of gender‐related self‐knowledge in single‐ and mixed‐sex settings, our study clarifies why single‐sex schooling helps adolescents to gain a better self‐concept of ability in school subjects that are considered inappropriate for their own sex.     

Predicting Self‐Confident Behaviour with Implicit and Explicit Self‐Esteem Measures

The present research compared the validity of popular direct and indirect measures of self‐esteem in predicting self‐confident behaviour in different social situations. In line with behavioural dual‐process models, both implicit and explicit self‐esteem were hypothesized to be related to appearing self‐confident to unacquainted others. A total of 127 participants responded to the Rosenberg Self‐Esteem Scale, the Multidimensional Self‐Esteem Scale, and an adjective scale for measuring explicit self‐esteem (ESE). Participants' implicit self‐esteem (ISE) was assessed with four indirect measures: the Implicit Association Test (IAT), the name‐letter task (NLT), and two variants of an affective priming task, the reaction‐time affective priming task (RT‐APT) and the error‐based affective priming task (EB‐APT). Self‐confident behaviour was observed in four different social situations: (i) self‐introduction to a group; (ii) an ostracism experience; (iii) an interview about the ostracism experience; and (iv) an interview about one's personal life. In general, appearing self‐confident to unknown others was independently predicted by ESE and ISE. The indirect measures of self‐esteem were, as expected, not correlated, and only the self‐esteem APTs—but not the self‐esteem IAT or the NLT—predicted self‐confident behaviours. It is important to note that in particular the predictive power of the self‐esteem EB‐APT pertained to all four criteria and was incremental to the ESE measures.

Maternal limit‐setting in toddlerhood: Socialization strategies for the development of self‐regulation

Early findings from the Prohibition Coding Scheme (PCS; Houck & LeCuyer, 1995; LeCuyer‐Maus & Houck, 2002; Medvin & Spieker, 1985) revealed that maternal limit‐setting styles with toddlers were differentially related to later child social competence, self‐concept, and delay of gratification. For this study, the PCS was revised to provide more information about the specific strategies mothers used during limit‐setting in relation to those outcomes. Results from the PCS‐Revised (PCS‐R; LeCuyer & Houck, 2004) included that the more time mothers spent actively distracting their toddlers away from a prohibited object during limit‐setting, as early as 12 months, the longer their children could delay gratification at age 5 years. Mothers who spent more time sensitively following and being engaged in their toddler's own interests (other than the prohibited object), again as early as 12 months, had more socially competent children with more developed self‐concepts at age 3 years. Maternal use of reasoning statements later in toddlerhood also related to higher levels of social competence. Maternal limits and prohibitions were not related to these outcomes, and appeared to contribute to the development of self‐regulation mainly by creating the opportunity for the use of other, less directive strategies. The findings indicate that these strategies may be important to include in intervention programs for the promotion of toddler and child development of self‐regulation.     

Avoidant coping as a mediator between appearance‐related victimization and self‐esteem in young Australian adolescents

Peer victimization, especially appearance‐related bullying, is a highly stressful experience for a young person and is associated with significant negative outcomes. Perhaps, the most common consequence of peer victimization in adolescence is lowered self‐esteem. Evidence supports the role of low self‐esteem as a non‐specific risk factor and high self‐esteem as a protective factor in the development of mental disorders and social problems in adolescence. Moreover, the literature indicates a robust negative relationship between avoidant coping (i.e. distracting oneself, wishing the situation would go away) and psychological well‐being. In this paper, we test a mediational model of the associations between appearance‐related victimization, avoidance coping and self‐esteem in young Australian adolescents. Boys (N = 194) and girls (N = 185) with a mean age of 11 years completed measures assessing self‐esteem, appearance‐related victimization and styles of coping. The results showed that avoidant coping partially mediates the association between appearance‐related bullying problems and self‐esteem among young adolescents. This finding provides a specific target for psychosocial interventions in schools.     

Positive academic emotions moderate the relationship between self‐regulation and academic achievement

Background. Research has shown how academic emotions are related to achievement and to cognitive/motivational variables that promote achievement. Mediated models have been proposed to account for the relationships among academic emotions, cognitive/motivational variables, and achievement, and research has supported such mediated models, particularly with negative emotions. Aims. The study tested the hypotheses: (1) self‐regulation and the positive academic emotions of enjoyment and pride are positive predictors of achievement; and (2) enjoyment and pride both moderate the relationship between self‐regulation and achievement. Sample. Participants were 1,345 students enrolled in various trigonometry classes in one university. Methods. Participants answered the Academic Emotions Questionnaire‐Math (Pekrun, Goetz, & Frenzel, 2005) and a self‐regulation scale (Pintrich, Smith, Garcia, & McKeachie, 1991) halfway through their trigonometry class. The students’ final grades in the course were regressed to self‐regulation, positive emotions, and the interaction terms to test the moderation effects. Results and Conclusions. Enjoyment and pride were both positive predictors of grades; more importantly, both moderated the relationship between self‐regulation and grades. For students who report higher levels of both positive emotions, self‐regulation was positively associated with grades. However, for those who report lower levels of pride, self‐regulation was not related to grades; and, for those who reported lower levels of enjoyment, self‐regulation was negatively related to grades. The results are discussed in terms of how positive emotions indicate positive appraisals of task/outcome value, and thus enhance the positive links between cognitive/motivational variables and learning.     

Self‐focused attention and social anxiety

Cognitive models propose that self‐focused attention (SFA) interacts with fear of negative evaluation to maintain social anxiety. Thus, the effect of SFA on anxiety would be expected to be specific to those with existing social concerns. However, much research suggests that the effect of SFA on anxiety occurs across anxiety levels. Manipulations of attention focus have been criticised for (1) lack of ecological validity and (2) eliciting fear of negative evaluation directly. The present study examined the role of SFA in social anxiety using an ecologically valid procedure that did not elicit fear of negative evaluation directly. Self‐reported anxiety was assessed among high and low socially anxious individuals under conditions of SFA or external‐focused attention. The manipulation successfully altered focus of attention but did not directly affect fear of negative evaluation or self‐reported anxiety. Taken together with the findings of previous studies, the results suggest that focusing on internal physiological states per se does not increase self‐reported social anxiety, and that self‐focus that does not have an explicitly evaluative dimension does not elicit social anxiety. The findings have implications for approaches to reducing social anxiety through reducing SFA.     

Contingent Punishment as a Double‐Edged Sword: A Dual‐Pathway Model from a Sense‐Making Perspective

A sense‐making perspective is adopted to explore how and when contingent punishment is related to job performance. Results from Study 1 support the prediction that contingent punishment is positively related to job performance through affective commitment and negatively related to job performance through self‐regulation impairment. Interpersonal justice on the part of supervisors strengthens the positive pathway, such that contingent punishment is more related to affective commitment when interpersonal justice is high. Core self‐evaluation of employees weakens the negative pathway, such that contingent punishment is less related to self‐regulation impairment when core self‐evaluation is high. Moderated mediation effects also show that the positive indirect effect of contingent punishment on job performance through affective commitment exists only when interpersonal justice is high and that the negative indirect effect of contingent punishment on job performance through self‐regulation impairment occurs only when core self‐evaluation is low. The results associated with the novel pathway mediated by self‐regulation impairment are replicated in Study 2.     

Expected consequences of anger‐related behaviours

In a study with 140 participants (66 men, 74 women), we investigated behaviour outcome expectancies (cognitive, affective and relational) regarding a broad group of anger‐related behaviours (e.g. hit someone, run away). Results of a three‐mode component analysis indicated that behaviour outcome expectancies vary considerably, depending on the behaviour (aggressive versus nonaggressive ones), the consequence (consequences related to the self versus consequences for the anger) and the individual. The findings are discussed in the context of catharsis theory, emotion regulation and functionalistic accounts of emotion‐related behaviour. Copyright © 2006 John Wiley & Sons, Ltd.     

The evolutionary psychology of small‐scale versus large‐scale politics: Ancestral conditions did not include large‐scale politics

The current research question sought to examine political psychology as it relates to evolutionary mismatch. The basic hypothesis is that people will be more cognitively prepared to think about political situations that are relatively small in scale compared with political situations that are large in scale. This research also examined the effects of whether the political situation is highly relevant to oneself. To test these questions, 49 young adults were presented with four sets of instructions. They were asked to write paragraphs describing (i) a large‐scale, self‐relevant political situation, (ii) a large‐scale non‐self‐relevant political situation, (iii) a small‐scale self‐relevant political situation, and (iv) a small‐scale non‐self‐relevant political situation. Paragraphs generated by the participants were analyzed using Tyler's ( 2013 ) Writing Sample Readability Analyzer. Results demonstrated that paragraphs designed for large‐scale political situations had more sentences and were less readable than paragraphs designed for small‐scale situations—while paragraphs designed for small‐scale political situations were relatively readable and included more words per sentence, suggesting that, consistent with the core hypothesis, participants had an easier time processing information related to small‐scale political situations than large‐scale political situations. Implications for the nature of modern politics are discussed.     

Adolescent development of insula‐dependent interoceptive regulation

Adolescence is hypothesized to be a critical period for the maturation of self‐regulatory capacities, including those that depend on interoceptive sensitivity, but the neural basis of interoceptive regulation in adolescence is unknown. We used functional magnetic resonance imaging and psychophysiology to study interoceptive regulation in healthy adolescent females. Participants regulated their gut activities in response to a virtual roller coaster by deep breathing aided by visually monitoring their online electrogastrogram (EGG) activity through a virtual thermometer (i.e. gut biofeedback), or without biofeedback. Analyses focused on the insula, given its putative role in interoception. The bilateral posterior insula showed increased activation in the no‐biofeedback compared to biofeedback condition, suggesting that the participants relied more on interoceptive input when exteroceptive feedback was unavailable. The bilateral dorsal anterior insula showed activation linearly associated with age during both induction and regulation, and its activation during regulation correlated positively with change of EGG in the tachygastria frequency band from induction to regulation. Induction‐related activation in the bilateral ventral anterior insula was nonlinearly associated with age and peaked at mid‐adolescence. These results implicate different developmental trajectories of distinct sub‐regions of the insula in interoceptive processes, with implications for competing neurobiological theories of female adolescent development.     

Mindfulness and integrative self‐knowledge: Relationships with health‐related variables

This study examined how mindfulness and integrative self‐knowledge were related to health‐related issues. Men in general population (n = 103) and coronary heart disease samples (n = 101) completed the Mindful Attention Awareness Scale, the Integrative Self‐knowledge Scale, the Type 2 subscale of the Interpersonal Reactions Inventory, the Perceived Stress Scale, and the Anxiety and Depression Scales. In both samples, there was a moderate positive correlation between mindfulness and integrative self‐knowledge and they were negatively correlated with all health‐related variables. However, only integrative self‐knowledge explained independent variance in health‐related variables. Specifically, in both samples, the relationship between mindfulness and health‐related variables was mediated by integrative self‐knowledge. Mindfulness and integrative self‐knowledge are related domains of self‐awareness that are associated with a range of health‐related variables. These relationships are robust across samples drawn from general population and patients with coronary heart disease. The finding that integrative self‐knowledge explained additional variance in the health‐related variables after the contribution of mindfulness had been accounted for suggests that reflective self‐awareness in integrative self‐knowledge may make a unique contribution to the explanation of individual differences in health variables.
