Engaging in imagery versus verbal processing of worry: Impact on negative intrusions in high worriers

Chronic, excessive, and uncontrollable worry is the defining characteristic of generalised anxiety disorder. Worry largely consists of verbal thought and it has been postulated that this predominance of verbal thought in worry may contribute to its perseveration. In an investigation of this issue, high worriers were trained to engage in either imagery or verbal processing. Mentation was sampled before and after a five-minute period of worry during which participants engaged in either imagery of the worry topic or verbal processing of the worry topic. Verbal worry resulted in a significant increase in negative intrusions, consistent with previous research. Furthermore, imagery was associated with a decrease in negative intrusions. The results support the theory that the predominantly verbal nature of worry may be responsible for the uncontrollability and maintenance of worry.     

Constructing a self: The role of self-structure and self-certainty in social anxiety

Current cognitive models stress the importance of negative self-perceptions in maintaining social anxiety, but focus predominantly on content rather than structure. Two studies examine the role of self-structure (self-organisation, self-complexity, and self-concept clarity) in social anxiety. In study one, self-organisation and self-concept clarity were correlated with social anxiety, and a step-wise multiple regression showed that after controlling for depression and self-esteem, which explained 35% of the variance in social anxiety scores, self-concept clarity uniquely predicted social anxiety and accounted for an additional 7% of the variance in social anxiety scores in an undergraduate sample (N = 95) and the interaction between self-concept clarity and compartmentalisation (an aspect of evaluative self-organisation) at step 3 of the multiple regression accounted for a further 3% of the variance in social anxiety scores. In study two, high (n = 26) socially anxious participants demonstrated less self-concept clarity than low socially anxious participants (n = 26) on both self-report (used in study one) and on computerised measures of self-consistency and confidence in self-related judgments. The high socially anxious group had more compartmentalised self-organisation than the low anxious group, but there were no differences between the two groups on any of the other measures of self-organisation. Self-complexity did not contribute to social anxiety in either study, although this may have been due to the absence of a stressor. Overall, the results suggest that self-structure has a potentially important role in understanding social anxiety and that self-concept clarity and other aspects of self-structure such as compartmentalisation interact with each other and could be potential maintaining factors in social anxiety. Cognitive therapy for social phobia might influence self-structure, and understanding the role of structural variables in maintenance and treatment could eventually help to improve treatment outcome.     

A New Model for Social Justice Supervision

Social justice supervision honors the identities of the supervisee and the client, teaches social justice skills to the supervisee, and prioritizes social justice counseling outcomes in the supervisee's counseling work. The purpose of this article is to describe a comprehensive model for social justice supervision that mandates supervisor self‐evaluation, explores supervisees' identities and strengths, emphasizes the social justice needs of clients, and uses social justice outcomes for clients as a measure of counseling success. Implications are explored.

Immunocytochemical Mapping of an RDL-Like GABA Receptor Subunit and of GABA in Brain Structures Related to Learning and Memory in the Cricket Acheta domesticus

The distribution of putative RDL-like GABA receptors and of γ-aminobutyric acid (GABA) in the brain of the adult house cricket Acheta domesticus was studied using specific antisera. Special attention was given to brain structures known to be related to learning and memory. The main immunostaining for the RDL-like GABA receptor was observed in mushroom bodies, in particular the upper part of mushroom body peduncle and the two arms of the posterior calyx. Weaker immunostaining was detected in the distal part of the peduncle and in the α and β lobes. The dorso- and ventrolateral protocerebrum neuropils appeared rich in RDL-like GABA receptors. Staining was also detected in the glomeruli of the antennal lobe, as well as in the ellipsoid body of the central complex. Many neurons clustered in groups exhibit GABA-like immunoreactivity. Tracts that were strongly immunostained innervated both the calyces and the lobes of mushroom bodies. The glomeruli of the antennal lobe, the ellipsoid body, as well as neuropils of the dorso- and ventrolateral protocerebrum were also rich in GABA-like immuno- reactivity. The data demonstrated a good correlation between the distribution of the GABA-like and of the RDL-like GABA receptor immunoreactivity. The prominent distribution of RDL-like GABA receptor subunits, in particular areas of mushroom bodies and antennal lobes, underlines the importance of inhibitory signals in information processing in these major integrative centers of the insect brain.     

The manipulation of color response times in a color-word interference task

The relationship between word and color response times and color-word interference is of theoretical importance for understanding the interference phenomenon. In this experiment, color response times were manipulated by varying the size of the color-word set, but there was no corresponding change in interference. Since the manipulation of word response times consistently leads to such changes, this result has certain implications which were briefly discussed.     

Do generation and regulation of emotions interact? Examination of their relationships in young adults

Emotions can be generated in response to inherently emotional perceptual properties of a stimulus (‘bottom up’) and in response to cognitive interpretations of an event (‘top down’). Similarly, emotion regulation (ER) strategies may deploy bottom-up or top-down processes, however the specific nature of these processes remains unclear. In this study we sought to replicate and extend previous studies that have investigated the interaction between ER and emotion generation. Specifically, we examined the relationship between both methods of emotion generation and ER in a sample of 75 undergraduate students who completed self-report questionnaires and a behavioral task of ER. We attempted to extend previous research by testing whether the positive effect of cognitive reappraisal on top-down generated emotions was specific to reappraisal or true of multiple ER strategies. Overall there was a main effect of generation such that top-down generated emotion was better regulated by cognitive reappraisal, expressive suppression, and appraisal strategies. We also found a main effect of ER such that cognitive reappraisal was perceived as the most successful ER strategy. We argue that ER is a state-dependent process that includes dynamic cycles between emotion generation and regulation processes. We further discuss expressive suppression as a top-down emotion regulation strategy in the context of our study despite debated literature.     

Respond,don’t react: The influence of mindfulness training on performance monitoring in older adults

A sizeable body of literature demonstrates positive effects of mindfulness training on brain, behavior, and psychological processes in both novice and expert practitioners as compared to non-meditators. However, only more recently has research begun to examine the specific mechanisms by which mindfulness exerts these effects. In the current study, we used event-related potentials (error-related negativity (ERN), error positivity (Pe)) to test the hypothesis that performance monitoring is one such mechanism. We conducted a randomized controlled trial in healthy older adults (n = 36), relevant because markers of performance monitoring are known to decline with normal aging. Compared to an active control condition, mindfulness participants showed an increase in the ERN, without an increase in the Pe. Participants in both groups reported a reduction in self-report of anxiety and self-judgment of one’s own mental functioning, indicating the subjective impression of benefit from each intervention type. The current results are important insofar as they support the purported self-regulatory functions of mindfulness (i.e., learning to respond, not react), as well as demonstrating that such positive effects can be obtained in an older adult sample, both of which have important implications for intervention.     

Temperament, executive functions, and the allocation of attention to punishment feedback in passive avoidance learning

Several theories have been proposed to account for the apparent non-responsiveness to punishment cues or aversive events demonstrated by members of some disinhibited groups. Included among these theories are those that emphasize individual differences in temperament, temperament-related biases associated with the allocation of attentional resources, and impairments in executive functions. This study examined the relative contribution of each of these variables to the prediction of passive avoidance errors (PAEs, or failures to inhibit responding to punishment cues) during a computerized go/no-go task. Variations in temperament, attentional allocation to punishment feedback, and executive functions were found to independently and additively contribute to the prediction of PAEs in a mixed sample of men and women recruited at a university campus (n=145). Results from this study, therefore, support multiple theoretical perspectives on PAEs as assessed by the go/no-go experimental paradigm.     

Social creativity strikes back: improving motivated performance of low status group members by valuing ingroup dimensions

Motivation of stigmatized group members to perform on status‐relevant ‘outgroup’ dimensions can be impaired after ingroup failure. Three experiments examined whether social creativity by valuing ingroup dimensions (dimensions on which an ingroup outperforms an outgroup) can increase motivation and performance on outgroup dimensions. It was hypothesized that under high social identity threat, motivation on the outgroup dimension would benefit from valuing an ingroup dimension. Experiments 1 and 2 show that when social identity threat is increased, low status group members who personally value ingroup dimensions show higher motivation to perform on the outgroup dimension. Experiment 3 shows that the induction of high contextual value of both ingroup and outgroup dimensions improves low status group members' well‐being and motivated performance on the outgroup dimension.
