Bottom-Up and Top-Down Processes in Emotion Generation: Common and Distinct Neural Mechanisms

ABSTRACT— Emotions are generally thought to arise through the interaction of bottom-up and top-down processes. However, prior work has not delineated their relative contributions. In a sample of 20 females, we used functional magnetic resonance imaging to compare the neural correlates of negative emotions generated by the bottom-up perception of aversive images and by the top-down interpretation of neutral images as aversive. We found that (a) both types of responses activated the amygdala, although bottom-up responses did so more strongly; (b) bottom-up responses activated systems for attending to and encoding perceptual and affective stimulus properties, whereas top-down responses activated prefrontal regions that represent high-level cognitive interpretations; and (c) self-reported affect correlated with activity in the amygdala during bottom-up responding and with activity in the medial prefrontal cortex during top-down responding. These findings provide a neural foundation for emotion theories that posit multiple kinds of appraisal processes and help to clarify mechanisms underlying clinically relevant forms of emotion dysregulation.     

Perceiving one’s own movements when using a tool

The present study examined what participants perceive of their hand movements when using a tool. In the experiments different gains for either the x-axis or the y-axis perturbed the relation between hand movements on a digitizer tablet and cursor movements on a display. As a consequence of the perturbation participants drew circles on the display while their covered hand movements followed either vertical or horizontal ellipses on the digitizer tablet. When asked to evaluate their hand movements, participants were extremely uncertain about their trajectories. By varying the amount of visual feedback, findings indicated that the low awareness of one’s own movements originated mainly from an insufficient quality of the humans’ tactile and proprioceptive system or from an insufficient spatial reconstruction of this information in memory.     

The use of snowball sampling for multi source organizational research: Some cause for concern

In snowball sampling for multisource studies, researchers ask target participants to recruit informants. Despite its widespread use, especially for recruiting informants for multisource research, virtually no published research has addressed possible biases snowball sampling may cause in findings of this type of research. Such potential biases were tested empirically in a multisource study with a sample of 1,058 employed students asked to collect online ratings from their supervisors and coworkers. Informant ratings were obtained for 358 target participants. Objective indicators were employed to identify informant ratings suspicious of being fabricated. Results indicated that target participants who report (a) better relationship quality with informants, (b) fewer organizational constraints, and (c) more favorable self‐evaluations on behaviors to be rated by informants were more likely to be included in multisource data unsuspicious of being fabricated. Inclusion of informant ratings suspicious of being fabricated led to inflated estimates of self‐other consensus and of variance accounted for in criterion measures, to deflated informant rating means, but also to a target sample less restricted in terms of relevant organizational variables. In sum, the present findings suggest that potential biases should be identified in future uses of snowball sampling. Some practical recommendations toward that end are derived.     

Comparing Cognitive Behavioral Therapy and Systemic Therapy for Social Anxiety Disorder: Randomized Controlled Pilot Trial (SOPHO-CBT/ST)

This randomized controlled trial (RCT) aimed to pilot the newly developed manualized and monitored systemic therapy (ST) for social anxiety disorder (SAD), as compared to manualized and monitored cognitive behavioral therapy (CBT). We conducted a prospective multicenter, assessor-blind pilot RCT on 38 outpatients (ICD F40.1; Structured Clinical Interview for DSM (SCID); Liebowitz Social Anxiety Scale, LSAS-SR >30). The primary outcome was level of social anxiety (LSAS-SR) at the end of treatment. A total of 252 persons were screened, and 38 patients were randomized and started therapy (CBT: 20 patients; ST: 18 patients; age: M = 36 years, SD = 14). Within-group, simple-effect intent-to-treat analyses (ITT) showed significant reduction in LSAS-SR (CBT:d = 1.04; ST:d = 1.67), while ITT mixed-design ANOVA demonstrated the advantage of ST (d = 0.81). Per-protocol analyses supported these results. Remission based on reliable change indices also demonstrated significant difference (LSAS-SR: 15% in CBT; 39% in ST;h: 0.550), supported by blind diagnosticians’ ratings of those who completed therapy (SCID; 45% in CBT, 78% in ST,p = .083). No adverse events were reported. CBT and ST both reduced social anxiety, supporting patient improvement with the newly developed ST for SAD; this has yet to be verified in a subsequent confirmatory RCT.     

Pleasure and pressure based prosocial motivation: Divergent relations to subjective well-being

We propose two fundamentally different motives for helping: gaining pleasure and fulfilling one’s duty (“pressure”). Using the newly developed Pleasure and Pressure based Prosocial Motivation Scale, we demonstrated the distinctiveness of pleasure and pressure based prosocial motivation in three studies. Although the two motives exhibited different relations to a variety of personality characteristics, they were similarly related to trans-situational helping. Of particular interest, pleasure based prosocial motivation was positively related to self-actualization, self-esteem, life satisfaction, and positive affect and negatively related to negative affect. On the contrary, pressure based prosocial motivation was unrelated to self-actualization, self-esteem, life satisfaction, and positive affect but positively related to negative affect. These results qualify research showing that prosocial life goals generally increase subjective well-being.     

Regret aversion and decision process quality: Effects of regret salience on decision process carefulness

A considerable amount of past research has examined the effects of regret aversion on which options decision makers choose. However, past research has largely neglected to address the effect of regret aversion on the decision process. We conducted five experiments to examine the effect of making regret salient on decision process quality. We predicted that increased regret aversion would lead to more careful decision processing. The results consistently supported this prediction across the different decision situations, incentive structures, regret salience manipulations, and dependent variables used. In all experiments making regret salient led decision makers to take significantly longer to reach a decision. In Studies 2a, 2b, and 4 it also led participants to collect significantly more information before making a choice. Implications and future directions are discussed.     

“How much do you like your name?” An implicit measure of global self-esteem

We introduce a single-item implicit measure of global self-esteem. The measure is based on the mere-ownership effect and asks participants to indicate how much they like their name. Six studies attested to the validity of this measure. In addition to showing high test-retest reliability (r = .85), the studies found that Name-Liking was (a) unrelated to impression management, (b) positively related to the Name-Letter-Task, the Self-Esteem IAT, explicit self-esteem measures, and self-reported subjective well-being, (c) more strongly related to explicit measures of global than domain-specific self-esteem, (d) more strongly related to self-esteem judgments made spontaneously as well as under cognitive load, and (e) predicted observer-reported anxiety during an anxiety-inducing interview whereas an explicit measure of self-esteem did not.     

Personality, political skill, and job performance

Based on the socioanalytic perspective of performance prediction [Hogan, R. (1991). Personality and personality assessment. In M. D. Dunnette, L. Hough, (Eds.), Handbook of industrial and organizational psychology (2nd ed., pp. 873–919). Chicago: Rand McNally; Hogan, R., & Shelton, D. (1998). A socioanalytic perspective on job performance. Human Performance, 11, 129–144.], the present study tests whether motives to get along and to get ahead produce greater performance when interactively combined with social effectiveness. Specifically, we investigated whether interactions of the Five-Factor Model constructs of agreeableness and conscientiousness with political skill predict job performance. Our results supported our hypothesis for the agreeableness-political skill interaction. Additionally, after correcting for the unreliability and restricted range of conscientiousness, we found that its interaction with political skill also significantly predicted job performance, although not precisely as hypothesized. Implications of the results and directions for future research are provided.     

Psychotherapie von Anpassungsstörungen

In this study we examined the effectiveness of an outpatient client-centered psychotherapy of patients with adjustment disorders (ICD-10 F43.2) limited to twelve sessions in comparison to an untreated control group. The patients of each group (n_treatment= 31 and n_control= 19) had been diagnosed with an adjustment disorder in response to one of the following stressful events: either the loss of an important person or performance deficits at work or university. Compared with the untreated control group the immediate therapy group improved significantly on rating scales and questionnaires. These positive treatment effects proved stable at a 3 months follow-up. Individual treatment gains were also analyzed for clinical and statistical significance. The improvements of the treatment group were significantly greater in all used measures than those of the control group. These improvements were interpreted as an effect of the client-centered treatment which resulted in high individual overall treatment gains and in high effectsizes.     

At your own peril: An ERP study of voluntary task set selection processes in the medial frontal cortex

A tool that is commonly used to investigate selection among different alternatives in a changing environment is the task-switching paradigm. Functional neuroimaging has pointed out a role for the posterior medial frontal cortex and the posterior parietal cortex in the voluntary selection of task sets. In the present study, we set out to investigate the temporal dynamics of these agency-related processes (in task choice vs. no-choice conditions) using event-related brain potentials (ERPs). The results revealed agency-related modulations of a series of ERP components, including (1) an early parieto-occipital activation, taken to reflect the evaluation of choice versus no choice; (2) a subsequent medial frontal expression of the voluntary selection between task sets; (3) a CNV-like sustained negativity in preparation for the target; (4) a target-induced N210—P210 complex, taken to reflect early sensory-perceptual processing; and (5) a target-induced P3, associated with the evaluation of the stimulus and its designated response vis-à-vis the chosen versus competing task sets. Together, these results indicate that the opportunity to choose between tasks invokes activity originating from the medial frontal cortex, associated with voluntary task set selection, but also activation at different time points in a number of other brain areas, not necessarily captured by functional neuroimaging.
