Traits and Adaptations: A Theoretical Examination and New Empirical Evidence

We investigated the distinction between traits (also labelled basic tendencies or dispositions) and (characteristic) adaptations, two related features of the personality system postulated to influence how personality manifests throughout the lifespan. Traits are alleged to be universal, causal, and enduring entities that exist across cultures and through evolutionary time, whereas learned adaptations are acquired through sustained interaction with cultural, physical, and social environments. Although this distinction is central to several personality theories, they provide few measurable criteria to distinguish between traits and adaptations. Moreover, little research has endeavoured to operationalize it, let alone test it empirically. Drawing on insights from four frameworks—the Five-Factor Theory, Cybernetic Big Five Theory, Disposition–Adaptation–Environment Model, and New Big Five—we attempted to investigate the distinction both theoretically and empirically. Using various experimental rating conditions, we first scored 240 questionnaire items in their degrees of definitionally reflecting traits and/or adaptations. Next, we correlated these definitional ratings with the items' estimates of rank-order stability, consensual validity, and heritability—criteria often associated with personality traits. We found some evidence that items rated as more trait-like and less adaptation-like correspond to higher cross-rater agreement and stability but not heritability. These associations survived controlling for items' retest reliability, social desirability, and variance. The theoretical and empirical implications of these findings are discussed. © 2020 European Association of Personality Psychology     

Brain states matter. A reply to the unfolding argument

Recently, it has been claimed that Integrated Information Theory and other theories of its type cannot explain consciousness (“unfolding argument”). We unravel this argument mathematically and prove that the premises of the argument imply a much stronger result according to which the observed problem holds for almost all theories of consciousness. We find, however, that one of the premises is unwarranted and show that if this premise is dropped, the argument ceases to work. Thus our results show that the claim of the unfolding argument cannot be considered valid. The premise in question is that measures of brain activity cannot be used in an empirical test of theories of consciousness.     

To share or not to share: A theoretically guided investigation of factors predicting intentions to use fully automated shared passenger shuttles

This study applied the Theory of Planned Behaviour (TPB) to assess individuals’ intentions to use fully automated shared passenger shuttles when they become publicly available. In addition, perceived trust was assessed to examine the extent to which this variable could account for additional variance in intentions above the TPB constructs of attitudes, subjective norms, and perceived behavioural control (PBC). Further, and also guided by the TPB, the study explored the differences in behavioural, normative, and control beliefs between individuals who reported high intentions to use automated passenger shuttles in the future (high intenders) and individuals who reported low intentions to use fully automated shared passenger shuttles in the future (low intenders). Participants (N = 438; 64% female) aged between 17 and 84 years (Mage = 35.42 years) were asked to complete an online questionnaire which took approximately 15 min. The findings revealed that attitudes, subjective norms, and PBC were significant positive predictors of intentions to use fully automated shared passenger shuttles when they become publicly available. When perceived trust was added to the hierarchical regression, this variable was shown to account for additional significant variance in intentions above the TPB constructs and was shown to be a significant positive predictor of intentions. Further, the results revealed significant differences in beliefs held by high and low intenders. Specifically, high intenders held significantly more positive beliefs towards fully automated shared passenger shuttles than low intenders. In turn, low intenders held significantly more negative beliefs towards these vehicles than high intenders. Overall, these findings provide support for the utility of the TPB in examining individuals’ intentions to use fully automated shared passenger shuttles when they become publicly available.     

Reliable measurement in sport psychology: The case of performance outcome measures

ObjectivesThe present research addresses a neglected aspect within the current Zeitgeist of improving methodological standards in (sport)psychology: reliable measurement. We discuss and highlight the importance of reliable measurement from different perspectives and empirically assess reliability of three commonly used performance outcome measures in order to give guidelines to researchers on how to increase reliability of measurements of performance outcomes.MethodIn three studies we estimate 5 different reliability coefficients for three performance outcome measures based on 14 golf putts (study 1; N = 100), 14 dart throws (study 2; N = 200; 100 sports students; 100 non-sports students) and 14 free throws in basketball (study 3; N = 192; 100 non-basketball players; 92 basketball players).ResultsThe highest reliability was the odd-even reliability for darts for the whole sample (0.888), followed by golf putts (0.714 for distance from the hole, 0.614 for successful putts) and free throws (0.504 non-basketball players; 0.62 for basketball players; and 0.826 for whole sample).ConclusionsBased on theoretical considerations and our empirical findings we give practical guidelines to improve reliability for performance outcome measures in sport psychology.     

A real‐world rational agent: unifying old and new AI

Explanations of cognitive processes provided by traditional artificial intelligence were based on the notion of the knowledge level. This perspective has been challenged by new AI that proposes an approach based on embodied systems that interact with the real‐world. We demonstrate that these two views can be unified. Our argument is based on the assumption that knowledge level explanations can be defined in the context of Bayesian theory while the goals of new AI are captured by using a well established robot based model of learning and problem solving, called Distributed Adaptive Control (DAC). In our analysis we consider random foraging and we prove that minor modifications of the DAC architecture renders a model that is equivalent to a Bayesian analysis of this task. Subsequently, we compare this enhanced, “rational,” model to its “non‐rational” predecessor and a further control condition using both simulated and real robots, in a variety of environments. Our results show that the changes made to the DAC architecture, in order to unify the perspectives of old and new AI, also lead to a significant improvement in random foraging.     

The Implications of Computer‐Mediated Communication (CMC) for Social Support Message Processing and Outcomes: When and Why Are the Effects of Support Messages Strengthened During CMC?

Widespread use of computer‐mediated communication (CMC) for exchanging social support has raised questions about the support‐related implications of CMC. This study drew from the dual‐process theory of supportive message outcomes and examined the implications of CMC for support message processing and outcomes. We hypothesized that the reduced social cues in CMC would encourage greater elaboration on support message content and lead support messages to have a greater impact than in face‐to‐face interaction. The results of the experiment showed that, although the support message was held constant, participants in the CMC condition reported the strongest motivation to receive support, engaged in the greatest level of message elaboration, and experienced the most beneficial changes in worry and uncertainty discrepancy.     

“Don’t you want the dream?”: Psycho-social determinants of car share adoption

The benefits of car share, in terms of reduced car ownership and sustainable transport use have been widely recognised. Knowledge of motivators and barriers of car share adoption is crucial to inform policy, and yet this aspect has received little attention so far. This paper aims to comprehensively explore the range of psycho-social factors which determine the adoption of car share.In this study, two theoretical approaches were used to explore psycho-social determinants of car share adoption. First, the Theory of Planned Behaviour is used as a theoretical lens to identify the role of attitudes, subjective norms and perceived behavioural control in car share adoption. Second, the Theory of Innovation Diffusion is used to examine the process of adoption of car share and the barriers at different stages. While the former considers the determinants of the binary decision of becoming a car share, the latter unpacks the process of car share adoption. This qualitative study draws on data from five focus groups and 18 semi-structured interviews, conducted in Melbourne, Australia, with station-based car share member, ex-members and non-members.Insights confirmed that while cost, convenience and environmental concerns are important motivators, others factors also encourage car share use including sharing with the community, reducing/avoiding hassles related to car ownership (e.g. maintenance, parking) and, a desire to own fewer material possessions. Normative beliefs about car ownership, perceived difficulties in using car share (e.g. with children) and the planning and effort required to book and use car share were identified as some of the barriers. Barriers related to car share use varied depending on the stage of car share adoption. Initial barriers related to a lack of knowledge and normative beliefs about car ownership. The study also highlighted how motivators and barriers might vary for peer-to-peer and fleet-based car share. Insights from this study will be useful for car share operators and policymakers to address the practical and social barriers to car share adoption.     

Comparison Types in the Semantic Extension of Diidxazá Body Part Terms

Body part terms (BPTs) are used extensively in Mesoamerican languages to name object parts. The process through which BPTs might be extended to refer to a part of an object and further serve as a relator in describing the relation between objects in space has often been attributed to metaphorical processes. This study proposes an alternative analysis following a Structure–Mapping Theory approach (Gentner, 1983, inter alia), based on data from Diidxazá (Isthmus Zapotec, Otomanguean) obtained through elicitation and experimental tasks. The data show that structure mapping does not depend on a 1:1 match of attributes; frequency of use shed light on principles that constrain the semantic extension of most BPTs; a core set of six BPTs are extended by abstraction of the set of intersecting axes of the body. The detailed nature of this study enables an analysis of the mental representations underlying the semantic extension of BPTs. This in turn elucidates on aspects of the relation between spatial language and spatial cognition. In addition, this study allows us to address questions about the categorial status of BPTs in Diidxazá and their lexicographic representation.     

The Allure of Aphrodite: How Gender‐Congruent Media Portrayals Impact Adult Women's Possible Future Selves

This study investigated how media exposure affects how noncollege women envision their futures. Over 5 days, a prolonged exposure experiment presented childless women (aged 21–35) with magazine portrayals of females in gender‐congruent (mother/homemaker or beauty ideals) or gender‐incongruent (professional) social roles. Responses to an open‐ended question revealed that 3 days after media exposure, only gender‐congruent roles remained salient. Exposure to homemaker portrayals induced more thoughts about possible future selves (PFSs) and fostered concerns about motherhood and career roles; it also produced more positive affective valence compared with exposure to portrayals of professional women, particularly among women with gender‐congruent life circumstances. Exposure impacts were mediated by the extent to which women linked the magazine portrayals to their own PFSs.
