Participants were asked to carry out a series of simple tasks while following mental control instructions. In advance of each task, they either suppressed thoughts of their intention to perform the task, concentrated on such thoughts, or monitored their thoughts without trying to change them. Suppression resulted in reduced reports of intentionality as compared to monitoring, and as compared to concentration. There was a weak trend for suppression to enhance reported intentionality for a repetition of the action carried out after (...) suppression instructions had been discontinued. (shrink)

Over-general autobiographical memory retrieval is characterized by retrieval of categoric autobiographical memories. According to the CarFAX model, this tendency may result from avoidance which functions to protect the person against recalling details of upsetting memories. This study tested whether avoidance strategies impact on the ability to retrieve specific autobiographical memories. Healthy participants watched a negative video clip and were instructed to either suppress any thought , suppress any feeling , or think and feel naturally in response to the video. Participants (...) then completed the Autobiographical Memory Test. Participants engaging in either thought suppression or emotional inhibition retrieved fewer categoric autobiographical memories than controls. These findings challenge the affect regulation component of the CarFAX model insofar as they suggest that regulatory strategies that aim to reduce awareness of adverse emotional memories do not necessarily lead to increased recall of categoric autobiographical memories.

The current research investigates the interaction between thought suppression and individuals’ explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts that individuals spontaneously noticed, individuals were frequently caught engaging in thoughts of their previous partner at experience-sampling probes. Furthermore, probe-caught thoughts were: associated with stronger decoupling of attention from the environment, more likely (...) to occur under cognitive load, more frequent for individuals with a desire to reconcile, and associated with individual differences in the tendency to suppress thoughts. Together, these data suggest that individuals can lack meta-awareness that they have begun to think about a topic they are attempting to suppress, providing novel insight into the cognitive processes that are involved in attempting to control undesired mental states.

Mental time travel is the ability to mentally project oneself into one’s personal past or future, in terms of memories of past events or projections of possible future events. We investigated the frequency and valence of involuntary MTT in the context of high trait worry. High and low worriers recorded the frequency and valence of involuntary memories and future projections using a structured notebook and completed measures probing individual differences related to negative affectivity. Involuntary future projections were as frequent as (...) involuntary memories. We found a positivity bias for both past and future MTT, in that fewer negative events were reported than positive or neutral ones. This positivity bias was greater for future than for past events. Individual differences related to negative affectivity were positively associated with the proportion of negative events, indicating a reduced positivity bias in individuals with a general tendency to experience negative affect.

Initial evidence suggests that suppressing a thought prior to sleep results in subsequent dreaming of that thought. The present research examined the influence of cognitive load on dreaming following suppression. In Experiment 1, 100 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and subsequently completed a dream diary. Participants instructed to suppress reported dreaming about the target thought more than controls; dream rebound was predicted by poorer performance on a working memory task. (...) In Experiment 2, 126 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and half of participants also had cognitive load of learning a 9-digit number. Participants receiving the suppression instruction under cognitive load reported greater dream rebound than other participants. These findings indicate that thought suppression prior to sleep leads to dream rebound, and this effect is enhanced by cognitive load. (shrink)

We examined two potential correlates of hypnotic suggestibility: dissociation and cognitive inhibition. Dissociation is the foundation of two of the major theories of hypnosis and other theories commonly postulate that hypnotic responding is a result of attentional abilities . Participants were administered the Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C. Under the guise of an unrelated study, 180 of these participants also completed: a version of the Dissociative Experiences Scale that is normally distributed in non-clinical populations; a latent inhibition (...) task, a spatial negative priming task, and a memory task designed to measure negative priming. The data ruled out even moderate correlations between hypnotic suggestibility and all the measures of dissociation and cognitive inhibition overall, though they also indicated gender differences. The results are a challenge for existing theories of hypnosis. (shrink)

The use of visual mental imagery has been proposed to be a risk factor for the development of bipolar disorder, due to its potential to amplify affective states. This study examined the relation between visual imagery , intrusive verbal thought, and hypomania, as assessed by self-report questionnaires, in a sample of young adults . Regression analyses found that levels of intrusive visual imagery predicted levels of hypomania, but that neither trait use of visual imagery nor intrusive verbal thought did. These (...) results were consistent with the proposal that being a ‘visualiser’, as opposed to a ‘verbaliser’, is a risk factor for bipolar disorder, with the caveat that it is specifically intrusive experiences of imagery, rather than the tendency to utilize imagery per se, that acts as a risk factor.

This perspective paper aims at discussing theoretical principles that could explain how emotion regulation and physical diseases mutually influence each other in the context of borderline personality disorder (BPD). Furthermore, this paper discusses the clinical implications of the functional relationships between emotion regulation, BPD and medical conditions considering dialectical behavior therapy (DBT) as a well-validated therapeutic intervention, which encompasses these issues. The inflexible use of maladaptive emotion regulation strategies (e.g., suppression, experiential avoidance, and rumination) might directly increase the probability of (...) developing physical diseases through a physiological pathway, or indirectly through a behavioral pathway. Some metabolic and chronic medical conditions could significantly impact emotional functioning through biological alterations involved in emotion regulation. Several empirical studies have shown high co-occurrence rates between BPD and several chronic physical diseases, especially ones linked to emotion-based maladaptive behaviors. DBT addresses physical diseases reported by individuals with BPD reducing problematic behaviors functionally associated to emotion dysregulation and identifying physical health as a goal forBuilding a Life Worth Living.

Background: Past research has highlighted the role of trauma in social adjustment problems, but little is known about the underlying process. This is a barrier to developing effective interventions for social adjustment of traumatized individuals. The present study addressed this research gap through a cognitive model.Methods: A total of 604 young adults from different backgrounds were assessed through self-report questionnaires. The data were analyzed through path analysis and multivariate analysis of variance. Two path analyses were conducted separately for migrant and (...) Australian groups.Results: Analyses indicated that cognitive avoidance and social problem solving can significantly mediate the relation between trauma and social adjustment. According to the model, reacting to trauma by cognitive avoidance can disturb the cognitive capacities that are required for social problem solving. Consequently, a lack of effective social problem solving significantly hinders social adjustment. There were no significant differences among the Australian, non-refugee immigrant and refugee participants on the dependent variables. Moreover, the hypothesized links between the variables was confirmed similarly for both migrant and Australian groups.Conclusion: The findings have important implications for interventions targeting the social adjustment of young individuals. We assert that overlooking the processes identified in this study, can hinder the improvement of social adjustment in young adults with a history of trauma. Recommendations for future research and practice are discussed. (shrink)
