RESUMEN

INTRODUCTION: Research on the link between affect and creativity rests on the assumption that creativity unfolds as a stimulus-driven response to affective states. We challenge this assumption and examine whether personality dynamics moderate the relationships between positive and negative mood with creativity. THEORETICAL MODEL: According to our model, personality dynamics that generate and maintain positive affect and downregulate negative affect energize creativity. Based on this model, we expect high creativity in response to negative mood if people engage in self-motivation and achieve a reduction in negative mood. We further derive that individual differences in action versus state orientation moderate the within-person relationship between mood and creativity. METHOD: We conducted an experience-sampling study and examined the relationship between mood and creativity in everyday work-life. Two hundred and ten participants indicated their action-state orientation and reported their mood three times a day over five consecutive workdays. At noon of each day, we assessed self-motivation and in the evening the extent to which participants had generated novel and useful ideas during the day. RESULTS: We observed high creativity when negative mood declined and self-motivation was high. Action-state orientation moderated the within-person relationships of positive and negative mood with creativity. CONCLUSION: Personality dynamics determine whether positive and negative mood result in creativity.

RESUMEN

According to the extended trust hypothesis, the ability to cope with negative experiences is grounded in intuitive positive feelings about one's existence (Kuhl, Quirin, & Koole, 2015). In the present study, the authors empirically tested this hypothesis by examining the nonlinear dynamics in a series of day-to-day autoregressive functions of affective states taken from a 30-day daily mood diary study among 40 participants. A parameter (?) related to the asymptotic level of day-to-day changes in implicit positive mood predicted action orientation, a personality variable that relates to coping with negative affect, and psychological symptoms. This effect did not emerge when using a similar parameter l for self-reported positive affect or any linear characteristic (mean or standard deviation) of changes in positive or negative mood. These findings are considered within the broader framework of Personality Systems Interaction theory (PSI theory) that interprets l, under specified conditions, as a form of basic trust that enables people to confront negative affect and permit self-growth through self-confrontational rather than defensive coping.

RESUMEN

OBJECTIVE: Implicit self-esteem, which is based on associative learning processes, is considered to be constituted earlier in life than explicit, verbalized self-esteem. While depressed individuals report negative explicit self-esteem, research has predominantly demonstrated equivalent levels of implicit self-esteem of depressed and healthy individuals. We further illuminate this finding by theorizing and empirically demonstrating that chronically depressed individuals show particularly low levels of implicit self-esteem when depression had an early onset. METHOD: We applied measures of implicit (name-letter test) and explicit (Rosenberg Self-Esteem Scale) self-esteem in chronically depressed patients with an early onset (N = 17), a late onset (N = 13), and an episodic depression (N = 29). RESULTS: As expected, patients with an early onset showed lower implicit self-esteem than the 2 other groups. CONCLUSION: Implicit self-esteem may function as a marker of how deeply negative self-views are internalized. Furthermore, the distinction between early and late onset of chronic depression seems to be valuable for classification and potentially treatment of unipolar depression.

RESUMEN

Personality systems interaction (PSI) theory postulates two executive control modes in volitional action: Self-control and self-regulation (self-motivation). Self-control should deplete energy whereas self-motivation should maintain energy and result in invigoration. There were three groups of participants: Self-control, self-motivation, and pretend, who performed a resource-demanding Stroop-Shift and an anagram task. Performance and energy expenditure were examined in each task. Compared to the other groups, the self-motivation group showed increments in blood glucose throughout the experiment, indicating invigoration, and had better performance on the difficult Stroop-Shift task than the self-control group. Additionally, for the self-motivation group anagram performance correlated with less effort and ease of concentration and was moderated by fun in the task. These results are consonant with the predictions of PSI and self-determination theories. It is concluded that self-control depletes resources whereas self-motivation is associated with invigoration in carrying resource-demanding tasks.

RESUMEN

Both theoretical approaches and empirical evidence suggest that negative affect fosters analytic processing, whereas positive affect fosters holistic processing, but these effects are inconsistent. We aim to show that (a) differences in affect regulation abilities ("action orientation") and (b) implicit more so than self-reported affect assessment need to be considered to advance our understanding of these processes. Forty participants were asked to verify whether a word was correctly or incorrectly spelled to measure analytic processing, as well as to intuitively assess whether sets of three words were coherent (remote associates task) to measure holistic processing. As expected, implicit but not explicit negative affect interacted with low action orientation ("state orientation") to predict higher d' performance in word spelling, whereas implicit but not explicit positive affect interacted with high action orientation to predict higher d' performance in coherence judgments for word triads. Results are interpreted according to personality systems interaction theory. These findings suggest that affect and affect changes should be measured explicitly and implicitly to investigate affect-cognition interactions. Moreover, they suggest that good affect regulators benefit from positive affect for holistic processing, whereas bad affect regulators benefit from negative affect for analytical processing.

RESUMEN

Interventions can foster personal growth. However, our understanding of the specific mechanisms for change and the types of interventions driving this growth process remains limited. In this study, we focused on emotion regulation ability as a potential mechanism. We examined the effects of an affirmation coaching intervention on changes in emotion regulation ability, an important facet of personality. In this coaching intervention, participants created a personal mantra/goal derived from a selected image and positive associations linked to this image (motto goals). This is considered to enhance emotion regulation abilities by internalizing self-stabilizing value. We assigned sixty-six participants to either this affirmation coaching intervention or one of two control coaching interventions: specific-goal versus indulgence coaching. Before and after each intervention, participants completed questionnaires. Only the affirmation coaching intervention significantly increased in adaptive aspects of personality. Notably, the affirmation coaching intervention increased emotion regulation ability, and this effect persisted even when controlling for extraversion and neuroticism. Furthermore, exploratory analysis showed that extraversion increased following the affirmation coaching, while neuroticism remained unchanged. Our results suggest that emotion regulation ability might be the key factor in personality growth. It could be more malleable and/or respond more strongly to short-term coaching, compared to neuroticism. Thus, the malleability of personality traits may not be an all-or-nothing phenomenon; rather, it could depend on the facet of emotion regulation ability. We discuss potential mechanisms of personality growth, distinguishing between emotion regulation and emotion sensitivity.

RESUMEN

Effectively managing to-do lists and getting things done is a desirable competence. However, when things get difficult or demanding, many individuals struggle to put their intentions into subsequent actions. According to Personality Systems Interactions (PSI) theory, changes in positive affect are decisive for efficient intention enactment. Based on this understanding, in the present study we designed and evaluated an affect-focused intervention that practices shifting between high and low positive affect. In a control group design (N = 252, Mage = 26.40, SD = 10.24, range 18-66) the affective shifting intervention was contrasted against two other conditions (affective boosting and neutral). To test our assumptions, personal real-life intentions were assessed, and multifaceted measures (self-report, nonreactive) were applied and measured at different time points. To evaluate affective shifting, we tested interindividual benefits in the Stroop task. Additionally, we analyzed intervention effects on positive affect and intention enactment in real life. In line with our assumptions, we found that specifically those individuals who struggle with intention enactment (i.e., state-oriented) benefited in terms of better intention enactment ability in the Stroop task. Further, affective shifting fostered the decisive self-regulation of positive affect that directly improved intention enactment 3 weeks after the intervention. Lastly, affective shifting led to more self-coherent intention enactment, meaning a greater integration of Expectancy × Value considerations 3 weeks after the intervention. Discussion of our findings highlights the importance of theory-driven and affect-related interventions to close the gap between intention and action.

RESUMEN

The achievement motive refers to a preference for mastering challenges and competing with some standard of excellence. Along with affiliation and power motives, the achievement motive is typically considered to occur on the level of implicit versus explicit representations. Specifically, whereas implicit motives involve pictorial, emotional goal representations and facilitate corresponding action effortlessly, explicit motives involve propositional ("verbalized") goal representations but need some effort to translate into action (McClelland et al., 1989). We used functional magnetic resonance imaging (fMRI) to investigate whether and to which degree the implicit and explicit achievement motives differentially predict blood-oxygen-level-dependent (BOLD) responses to pictures of individuals engaging in challenging activities. Whereas the implicit AM predicted activity in areas associated with emotion (orbitofrontal cortex) and visual processing (right dorsolateral prefrontal cortex, premotor and occipital cortices), the explicit AM predicted activity in areas associated with cognitive self-control or verbal goal processing (dorsal anterior cingulate cortex, left dorsolateral prefrontal cortex). The findings support the commonly assumed distinction between implicit and explicit motives with neuronal data. They also suggest that explicit motives require cognitive self-control to overcome potential lacks of motivation.

RESUMEN

Humans are unconditionally confronted with social expectations and norms, up to a degree that they, or some of them, have a hard time recognizing what they actually want. This renders them susceptible for introjection, that is, to unwittingly or "unconsciously" mistake social expectations for self-chosen goals. Such introjections compromise an individual's autonomy and mental health and have been shown to be more prevalent in individuals with rumination tendencies and low emotional self-awareness. In this brain imaging study, we draw on a source memory task and found that introjections, as indicated by imposed tasks that are falsely recognized as self-chosen, involved the bilateral medial prefrontal cortex (MPFC) and the dorsal anterior cingulate cortex (ACC). Notably, reduced right MPFC activation within this condition correlated with trait scores of ruminations and reduced emotional self-awareness, but also introversion. Moreover, correct recognition of tasks as self-chosen involved the right MPFC. Accordingly, the right MPFC may play a role in supporting the maintenance of psychological autonomy and counteract introjection, which individuals with certain personality traits seem to be prone to. This research has significant implications for the study of mechanisms underlying autonomous motivation, goal and norm internalization, decision-making, persuasion, education, and clinical conditions such as depression and burnout.

RESUMEN

Upregulation of implicit positive affect (PA) can act as a mechanism to deal with negative affect. Two studies tracked temporal changes in positive and negative affect (NA) assessed by self-report and the Implicit Positive and Negative Affect Test (IPANAT; Quirin, Kazen, & Kuhl, 2009). Study 1 observed the predicted increases in implicit PA after exposure to a threat-related film clip, which correlated positively with the speed of recognising a happy face among an angry crowd. Study 2 replicated increases in implicit PA after exposition to the same film clip, and showed that such increases were enhanced by priming self-referential stimuli. The findings are discussed against the background of personality systems interaction (PSI) theory (Kuhl, 2000, 2001), which emphasises the role of the implicit self in affect regulation.

RESUMEN

The aims of this study are to investigate suicidal behaviors among adolescents and young adults and to test an index composed using Rorschach test responses related to an increased risk of suicide. Using a cross-sectional design, 4 groups were studied (according to criteria of the Columbia Classification Algorithm of Suicide Assessment [Posner, Oquendo, Gould, Stanley, & Davies, 2007]): A group with suicidal ideation (n = 30), a group with parasuicidal behavior (n = 30), a group with near-lethal suicide attempts (n = 26), and a control group (n = 30). Responses to the Rorschach test yielded 6 potential indicators of suicidal behavior (scored according to Exner's Comprehensive System and the Suicidal Index for Adolescents; Silberg & Armstrong, 1992 ). Rorschach scores including at least 4 of these 6 indicators selected 69% of the people who had committed serious suicide attempts. The Rorschach Suicidal Index reached an acceptable reliability and was related to other criteria of suicide risk, such as the Beck Depression Inventory (BDI; Beck, Ward, Mendelsohn, Mock, & Erbaugh, 1961) and Linehan Reasons for Living Inventory (RFL-I; Linehan, Goodstein, Nielsen, & Chiles, 1983). Moreover, the Rorschach Suicidal Index showed incremental validity over the BDI and the RFL-I to predict suicidal behavior. A path analysis additionally showed that low social support was an important mediator between the Rorschach Suicidal Index and the number of suicide attempts committed by participants.

RESUMEN

Emotions have long been seen as counteracting rational thought, but over the last decades, they have been viewed as adaptive processes to optimize human (but also animal) behaviour. In particular, positive affect appears to be a functional aspect of emotions closely related to that. We argue that positive affect as understood in Kuhl's PSI model of the human cognitive architecture appears to have an interpretation in state-of-the-art hybrid robot control architectures, which might help tackle some open questions in the field.

RESUMEN

Emotion regulation ability (ERA) enables individuals to disengage from negative stimuli. In this study, we investigated the role of ERA in the depression-related negativity bias. Seventy-four individuals with major depressive disorder and eighty-three nonclinical individuals were screened for depressiveness using the Beck Depression Inventory. ERA was assessed using the Action Orientation After Failure Subscale of the Action Control Scale. We used a classical Stroop task variant, wherein the color words were preceded by either a self-relevant positive (success-related), negative (failure-related), or neutral word prime. The expected depressiveness × emotional prime interaction did not reach significance but the expected ERA × emotional prime interaction did. The latter effect was qualified by a three-way interaction between ERA, depressiveness, and emotional prime. Specifically, ERA predicted the negativity bias in individuals with high depressiveness scores. Using the Johnson-Neyman technique, we found that this effect was significant at the level of mild to moderate depression and beyond. Thus, poor ERA in individuals with depression may cause the depression-related negativity bias, whereas (at least) moderate ERA may protect individuals with depression from this bias. Future studies should assess ERA in individuals with depressive symptomatology and investigate how it influences their everyday functioning and treatment outcomes.

RESUMEN

BACKGROUND: Identifying pain-related response patterns and understanding functional mechanisms of symptom formation and recovery are important for improving treatment. OBJECTIVES: We aimed to replicate pain-related avoidance-endurance response patterns associated with the Fear-Avoidance Model, and its extension, the Avoidance-Endurance Model, and examined their differences in secondary measures of stress, action control (i.e., dispositional action vs. state orientation), coping, and health. METHODS: Latent profile analysis (LPA) was conducted on self-report data from 536 patients with chronic non-specific low back pain at the beginning of an inpatient rehabilitation program. Measures of stress (i.e., pain, life stress) and action control were analyzed as covariates regarding their influence on the formation of different pain response profiles. Measures of coping and health were examined as dependent variables. RESULTS: Partially in line with our assumptions, we found three pain response profiles of distress-avoidance, eustress-endurance, and low-endurance responses that are depending on the level of perceived stress and action control. Distress-avoidance responders emerged as the most burdened, dysfunctional patient group concerning measures of stress, action control, maladaptive coping, and health. Eustress-endurance responders showed one of the highest levels of action versus state orientation, as well as the highest levels of adaptive coping and physical activity. Low-endurance responders reported lower levels of stress as well as equal levels of action versus state orientation, maladaptive coping, and health compared to eustress-endurance responders; however, equally low levels of adaptive coping and physical activity compared to distress-avoidance responders. CONCLUSIONS: Apart from the partially supported assumptions of the Fear-Avoidance and Avoidance-Endurance Model, perceived stress and dispositional action versus state orientation may play a crucial role in the formation of pain-related avoidance-endurance response patterns that vary in degree of adaptiveness. Results suggest tailoring interventions based on behavioral and functional analysis of pain responses in order to more effectively improve patients quality of life.

RESUMEN

OBJECTIVE: Findings on the relationship between hypothalamus-pituitary-adrenocortical (HPA) activity and cognitive performance are inconsistent. We investigated whether personality in terms of emotion regulation abilities (ERA) moderates the relationship between stress-contingent HPA activity and accuracy of intuitive coherence judgments. METHOD: ERA and cortisol responses to social-evaluative stress as induced by a variant of the Trier Social Stress Test were measured in N = 49 participants (32 female, aged 18 to 33 years, M = 22.48, SD = 3.33). Subsequently, in a Remote Associates Task they provided intuitive judgments on whether word triples, primed by either stress-reminding or neutral words, are coherent or not. RESULTS: Under relative cortisol increase participants low in ERA showed reduced performance whereas individuals high in ERA showed increased performance. By contrast, under conditions of low cortisol change, individuals low in ERA outperformed those high in ERA. CONCLUSION: Personality can moderate the link between stress and cognition such as accurate intuition. This can happen to a degree that existing effects may not be become apparent in the main effect (i.e. without considering personality), which highlights the necessity to consider personality in stress research, ERA in particular. We discuss the findings with respect to individual differences in neurobehavioral mechanisms potentially underlying ERA and corresponding interactions with cognitive processing.

RESUMEN

This article introduces an instrument for the indirect assessment of positive and negative affect, the Implicit Positive and Negative Affect Test (IPANAT). This test draws on participant ratings of the extent to which artificial words subjectively convey various emotions. Factor analyses of these ratings yielded two independent factors that can be interpreted as implicit positive and negative affect. The corresponding scales show adequate internal consistency, test-retest reliability, stability (Study 1), and construct validity (Study 2). Studies 3 and 4 demonstrate that the IPANAT also measures state variance. Finally, Study 5 provides criterion-based validity by demonstrating that correlations between implicit affect and explicit affect are higher under conditions of spontaneous responding than under conditions of reflective responding to explicit affect scales. The present findings suggest that the IPANAT is a reliable and valid measure with a straightforward application procedure.

RESUMEN

Self-report measures assess mental processes or representations that are consciously accessible. In contrast, implicit measures assess automatic processes that often operate outside awareness. Whereas self-report measures have often failed to show expected relationships with endocrine stress responses, little effort has been made to relate implicit measures to endocrine processes. The present work examines whether implicit affectivity as assessed by the Implicit Positive and Negative Affect Test (IPANAT) predicts cortisol regulation. In Study 1, implicit low positive affectivity, but not negative affectivity, significantly predicted circadian cortisol release. In Study 2, implicit negative affectivity, but not positive affectivity, significantly predicted the cortisol response to acute stress. By contrast, cortisol regulation was not predicted by self-reported affectivity. The findings support the use of implicit affectivity measures in studying individual differences in endocrine stress responses and point to a differential role of positive and negative affectivity in baseline versus stress-contingent cortisol release, respectively.

RESUMEN

The relationship between work-life balance (WLB) (i.e. the perceived sufficiency of the time available for work and social life) and well-being is well-documented. However, previous research failed to sufficiently explain why this relationship exists. In this research, the hypothesis was tested that a sufficient amount of the time available increases well-being because it facilitates satisfaction of personal needs. Using two separate samples (students and employees), the mediating role of need fulfilment in the relationship between WLB and well-being was supported. The results suggest that perceived sufficiency of the time available for work and social life predicts the level of well-being only if the individual's needs are fulfilled within that time.

RESUMEN

OBJECTIVE: Our study investigated body image representations in female patients with anorexia nervosa and healthy controls using a size estimation with pictures of their own body. We also explored a method to reduce body image distortions through right hemispheric activation. METHOD: Pictures of participants' own bodies were shown on the left or right visual fields for 130 ms after presentation of neutral, positive, or negative word primes, which could be self-relevant or not, with the task of classifying the picture as "thinner than", "equal to", or "fatter than" one's own body. Subsequently, activation of the left- or right hemispheric through right- or left-hand muscle contractions for 3 min., respectively. Finally, participants completed the size estimation task again. RESULTS: The distorted "fatter than" body image was found only in patients and only when a picture of their own body appeared on the right visual field (left hemisphere) and was preceded by negative self-relevant words. This distorted perception of the patients' body image was reduced after left-hand muscle contractions (right hemispheric activation). DISCUSSION: To reduce body image distortions it is advisable to find methods that help anorexia nervosa patients to increase their self-esteem. The body image distortions were ameliorated after right hemispheric activation. A related method to prevent distorted body-image representations in these patients may be Eye Movement Desensitization and Reprocessing (EMDR) therapy.
