Personality Traits: Hierarchically Organized Systems

Personality science has always been and is still ready for new theorizing on traits. Accordingly, this article presents the recently proposed traits as hierarchical systems (THS) model, where personality traits are not only the emergent properties of the three-level hierarchy of the personality system, but are also hierarchical per se. As hierarchical systems, they are organized into three levels: mechanisms and processes, structures, and behavioral markers. In this approach, trait denotes the underlying, recurrent mechanisms that pattern its structure and account for the stability/variability of individual characteristics. Here, traits might be described as processes with a slow rate of change that can be substituted for structure. The main function of personality traits, within the personality system, is stimulation processing. Three dominant functions of stimulation processing in traits are proposed: reactive, regulative, and self-regulative. Some important questions regarding the concept of trait remain, such as those concerning trait stability, determinacy, measurement, their relation to overt behaviors, personality type or state, and differentiation between temperament traits and other-than-temperament personality traits. All of these topics are discussed in this article, as well as the compatible and distinctive features of this approach in relation to selected modern trait theories.

Anxiety and depression: toward overlapping and distinctive features

ABSTRACT This Special Issue of Cognition and Emotion addresses one of the cardinal concerns of affective science, which is overlapping and distinctive features of anxiety and depression. A central finding in the study of anxiety and depression is that they are moderately highly correlated with each other. This leads us to the question: What is behind this co-occurrence? Possible explanations relate to poor discriminant validity of measures; both emotional states are associated with negative affect; stressful life events; impaired cognitive processes; they share a common biological/genetic diathesis. However, despite a set of common (nonspecific) features, anxiety and depression are clearly not identical emotional states. Differences between them might be best viewed, for example, through their heterogeneous and multi-layered nature, adaptive functions and relations with regulatory processes, positive affect, and motivation or complex cognitive processes. In this introduction we consider several approaches (e.g. functional approach; tripartite model and content-specificity hypothesis) to which most research in this Special Issue is relevant. In addition, we have asked contributors to this Special Issue to indicate how their own studies on comparisons between anxiety and depression and models on anxiety and depression move this area of research to more mature science with applicability.

Attentional processing of emotional material in types of anxiety and depression

ABSTRACT The present study was designed to address the hypothesis that differences and similarities in patterns of attentional processing in recently proposed types of anxiety and depression are connected with the dominant (reactive, regulative) function they play in stimulation processing and their structural components. Participants (N = 1247) filled out the Anxiety and Depression Questionnaire, which assesses types of anxiety and depression, and completed the Emotional Faces Attentional Test one week later. The obtained results confirmed our prediction and suggested that the proposed typology of anxiety and depression is valid in the adaptive meanings of both phenomena.

Status of the Trait Concept in Contemporary Personality Psychology: Are the Old Questions Still the Burning Questions?: Contemporary Trait Concepts

This special issue of Journal of Personality addresses one of the cardinal concerns of personality psychology, namely, the status of traits in contemporary personality science. Trait theory is a major scientific model for personality explanation and research. Although there have been critiques of traits, typically formulated from the point of view of the social-cognitive perspective, the trait approach can be viewed as a continuously developing paradigm. However, personality psychology persists in tackling burning questions concerning the status of traits that need to be answered. Modern trait approaches confront problems such as constructing an objective personality traits assessment, connecting the descriptive traits with explanatory processes, applying traits for understanding the individual person, clarifying the relation of traits to behavior, and using traits for solving cardinal concerns of personality psychology (e.g., personality organization). This special issue presents examples of contemporary trait theories that attempt to provide possible solutions to these issues and/or delineate other main issues to be resolved by future research and theorizing. We have asked contributors to portray their approach and describe in what way their trait theory continues a historic tradition and in what respect it breaks with the past and moves trait models to more mature scientific levels.

Types of Anxiety and Depression: Theoretical Assumptions and Development of the Anxiety and Depression Questionnaire

The present paper is addressed to (1) the validation of a recently proposed typology of anxiety and depression, and (2) the presentation of a new tool—the Anxiety and Depression Questionnaire (ADQ)—based on this typology. Empirical data collected across two stages—construction and validation—allowed us to offer the final form of the ADQ, designed to measure arousal anxiety, apprehension anxiety, valence depression, anhedonic depression, and mixed types of anxiety and depression. The results support the proposed typology of anxiety and depression and provide evidence that the ADQ is a reliable and valid self-rating measure of affective types, and accordingly its use in scientific research is recommended.

Two Sides of the Same Coin: ERP and Wavelet Analyses of Visual Potentials Evoked and Induced by Task-Relevant Faces

New analysis techniques of the electroencephalogram (EEG) such as wavelet analysis open the possibility to address questions that may largely improve our understanding of the EEG and clarify its relation with related potentials (ER Ps). Three issues were addressed. 1) To what extent can early ERERP components be described as transient evoked oscillations in specific frequency bands? 2) Total EEG power (TP) after a stimulus consists of pre-stimulus baseline power (BP), evoked power (EP), and induced power (IP), but what are their respective contributions? 3) The Phase Reset model proposes that BP predicts EP, while the evoked model holds that BP is unrelated to EP; which model is the most valid one? EEG results on NoGo trials for 123 individuals that took part in an experiment with emotional facial expressions were examined by computing ERPs and by performing wavelet analyses on the raw EEG and on ER Ps. After performing several multiple regression analyses, we obtained the following answers. First, the P1, N1, and P2 components can by and large be described as transient oscillations in the α and θ bands. Secondly, it appears possible to estimate the separate contributions of EP, BP, and IP to TP, and importantly, the contribution of IP is mostly larger than that of EP. Finally, no strong support was obtained for either the Phase Reset or the Evoked model. Recent models are discussed that may better explain the relation between raw EEG and ERPs.

Cognitive Emotion Regulation Strategies in Anxiety and Depression Understood as Types of Personality

The identification of distinctive and overlapping features of anxiety and depression remains an important scientific problem. Currently, the literature does not allow to determine stable similarities and differences in the use of cognitive emotion regulation strategies (CERS) in anxiety and depression, especially concerning the adaptive strategies. Consequently, the aim of this study was to identify the overlapping and distinctive patterns of CERS use in the recently proposed types of anxiety and depression in a general population. In this dimensional approach, types of anxiety and depression are considered as personality types and distinguished based on their specific structural composition and functional role (reactive or regulative) in stimulation processing. 1,632 participants from a representative sample completed the Anxiety and Depression Questionnaire (measuring the Arousal and Apprehension Types of anxiety and the Valence and Anhedonic Types of depression) and the Cognitive Emotion Regulation Questionnaire. Regression analyses were conducted with the affective types as predictors. The co-occurrence of the types was accounted for in order to examine their independent relationships with the CERS. We found that reactive arousal anxiety was not related to any strategies, while regulative apprehension anxiety primarily predicted the use of rumination, which is presumably related to the types cognitive structural components. The strategy specific to reactive valence depression was other-blame (as predicted by the high negative affect in its structure), and the regulative, most structurally complex anhedonic depression predicted the use of the largest number of strategies, including the adaptive ones. The relationships between the types of depression and self-blame and refocus on planning were moderated by sex but the effects were small. These findings fit into the current trend of exploring the shared and specific features of anxiety and depression, which might facilitate their differentiation by identifying CERS that are characteristic for the specific types. This information can be used for supporting diagnosis and targeting selected strategies in therapy both in clinical and non-clinical populations.
