Long term consequences of suppression of intrusive anxious thoughts and repressive coping

The current experiment employed a thought suppression paradigm to investigate whether repressors (N=40) are more skilled in suppressing positive and anxious autobiographical thoughts than low anxious (N=40), high anxious (N=40), and defensive high anxious (N=40) individuals, both immediately and over a longer time period (i.e., 7 days). Regardless of suppression instructions, repressors reported during their lab visit fewer target thoughts for their most anxious events than participants in the other three groups. However, over a 7 days period, repressors showed the highest number of intrusive thoughts about their anxious autobiographical events. Thus, our results demonstrate that repressive coping might be adaptive in the short run, but counterproductive in the long run.     

Suppressing thoughts of past events: Are repressive copers good suppressors?

We investigated the ability of individuals with a “repressive coping style” to strategically control thoughts of events from their past, which made them feel either proud or embarrassed, within the thought suppression paradigm. We examined whether (low) anxiety and (high) defensiveness interacts to influence suppression success over and above anxiety and defensiveness alone using low anxious, repressor, high anxious, and defensive high anxious groups. For the emotionally positive “proud event”, all groups avoided event‐related thoughts when instructed to suppress. For the emotionally negative “embarrassed event”, repressors reported fewer event‐related thoughts than all other groups, even when not instructed to suppress. Repressors also reported the lowest level of suppression effort and showed no “rebound”. We discuss repressors' memory performance in terms of their natural tendency to avoid negative self‐referent material, and thought and memory control in everyday life.     

Individual differences in self-reported thought control: the role of the repressive coping sytle

The purpose of the present research is to assess differences between repressors and non repressors in some aspects associated with conscious thought control. Thus, Sixty-three Spanish university students with different combinations of trait anxiety and defensiveness completed the Thought Control Ability Questionnaire (TCAQ) and the White Bear Suppression Inventory (WBSI). Data analysis showed that subjects with low anxiety (repressors and low anxious) reported higher perceived ability to control unpleasant thoughts and less tendency to suppress than did subjects with high anxiety (high anxious and defensive high anxious). Implications of these results are discussed in relation to recent researches that have explored the association between repression and thought suppression.     

Voluntary involuntariness: thought suppression and the regulation of the experience of will

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.     

Attempting suppression of traumatic memories over extended periods in acute stress disorder

This study investigated the influence of attempted suppression and thought control strategies on traumatic memories. Survivors of civilian trauma with acute stress disorder (ASD; n = 20) and without ASD (n = 20) monitored their trauma-related thoughts for three 24-h periods. In period 1, participants were instructed to think about anything. In period 2, participants were administered suppression or nonsuppression instructions relating to thoughts of the trauma. In period 3, participants were again instructed to think about anything. The results revealed no evidence for an increase in trauma-related thoughts following suppression instructions. Punishment and worry thought control strategies correlated significantly with both anxiety and suppression ratings. Frequency of intrusions was associated with a distraction cognitive strategy. These findings point to the importance of traumatised individuals' cognitive strategies in mediating the management and occurrence of posttraumatic intrusions.     

False Memories for an Analogue Trauma: Does Thought Suppression Help or Hinder Memory Accuracy?

In the current study, we investigated whether suppression can produce an amplified memory for a traumatic experience. Participants viewed a distressing film depicting a multi‐fatality car accident. We broke the film down into several short clips, some of which were removed. After viewing the film, we instructed participants to (i) suppress and monitor film‐related thoughts, (ii) think freely and monitor film‐related thoughts or (iii) just think freely. Twenty‐four hours later, participants completed a recognition test. Memory distortion was comparable across conditions; however, suppression and monitoring of trauma‐related thoughts removed the typical bias to falsely remember the most critical and traumatic clips of the film over the least critical clips. Our data suggest that suppression may be effective in reducing trauma‐related cognitions and, therefore, does not predict a more ‘amplified’ memory for trauma. Instead, suppression and thought monitoring encourage an unbiased, although inaccurate, memory for trauma.Copyright © 2016 John Wiley & Sons, Ltd.     

Thought listing and endorsement measures of self-referential thinking in test anxiety

Abstract

The primary purpose of the present study was to examine cognitive reactions of high and low test-anxious subjects while performing a task of extreme difficulty. A sample of 44 subjects (28 females, 16 males) attempted a difficult analogies task and then reported their thoughts during the task. Subjects also completed the Sarason Test Anxiety Scale and several other self-report measures of their cognitive reactions to the task. Thought listings were classified according to their referent (self, task, or unrelated) and their valence (positive, negative, or neutral). Correlational analyses were then performed with the various measures and revealed an association between test anxiety and reports of negative thoughts involving the self. Test anxiety was not related significantly to the number of thoughts involving the task nor to actual performance on the task. However, test-anxious subjects did report more negative expectancies for their performance and greater cognitive interference during the task. Negative self-expectancies were also related to more negative self thoughts, fewer positive self thoughts, and fewer positive task-related thoughts. The results are interpreted as further evidence for both the role of negative self-related cognitions in the experience of test anxiety and the usefulness of unstructured measures in anxiety research.     

Effects of priming and suppression of worry

High and low worriers were primed by a short period of worry, suppression of worry, or the same period of non-worrying thought. Analysis of thoughts during the period following showed that worriers had more than twice as many unpleasant thoughts as did controls, across all prior conditions. Priming condition had little effect on this difference, although worry suppression was associated with a slight increase in the frequency of neutral or pleasant thoughts in high worriers, and a slight decrease in controls. These results are taken as evidence against the hypothesis that suppression of upsetting thoughts increases their intrusive quality, and thereby contributes to anxiety disorders.     

Effects of suppression and appraisals on thought frequency and distress

Cognitive theories of obsessions highlight appraisals of personal significance and thought suppression in the development and maintenance of intrusive thoughts. The current study examined the role of personal significance within the context of a thought suppression paradigm. The primary aim was to examine whether suppression would have differential effects for target thoughts appraised as personally meaningful versus relatively unimportant. A blasphemous thought served as the target thought, and highly religious and nonreligious participants were recruited. Participants completed a two-interval thought suppression task; during interval 1 they were randomly assigned to suppress or not suppress the target thought and during interval 2, all participants were given “do not suppress” instructions. Suppression resulted in sustained frequency of thoughts in contrast to the decline in thought frequency observed for non-suppression. Differential effects of suppression were found across the two groups. Moreover, suppression was associated with increased negative mood and anxiety. Results suggest that suppression of personally meaningful thoughts is a counterproductive strategy.     

Suppression of obsession-like thoughts in nonclinical individuals: impact on thought frequency, appraisal and mood state

Wegner's (1994, Psychological Review, 101, 34-52) research on the paradoxical effect of thought suppression has been incorporated into contemporary cognitive-behavioural models of obsessive-compulsive disorder. However, findings on the effects of thought suppression on thought frequency have been inconsistent and few studies have actually examined the suppression of thoughts that are obsessional in nature. In the present study 219 nonclinical participants were randomly assigned to suppress or not suppress a neutral, obsessional or positive thought during an initial monitoring interval. In a second thought monitoring interval, all participants received instructions not to suppress their target thought. No paradoxical effect of suppression on frequency was observed for any type of thought, although suppression of obsessional thoughts was associated with greater subsequent discomfort and a more negative mood state than suppression of positive or neutral target thoughts.     

Thought suppression failures in combat PTSD: A cognitive load hypothesis

The present study investigated the relation between thought suppression of emotionally neutral content [i.e., Wegner's (1994) “white bear”], incidental traumatic thought intrusion, and skin conductance responses in combat-related Posttraumatic Stress Disorder (PTSD). Participants included service members who either: a) had PTSD following an Operation Iraqi Freedom deployment; b) were free of psychiatric diagnosis following deployment (Combat Equivalent), or c) were pre-deployed and without psychiatric diagnosis (Pre-Deployed). PTSD Service Members reported the greatest intrusion of combat thoughts during the suppression task and demonstrated a post-suppression rebound effect with a neutral thought. Non-specific skin conductance responses indicated that the suppression task was related to similar levels of increased sympathetic activity for both the PTSD and Pre-Deployed groups, whereas the Combat Equivalent group showed no increased activation during thought suppression. Intrusive traumatic thoughts combined with failures in neutral thought suppression may be a consequence of increased cognitive load in PTSD.     

Perceived emotion suppression and culture: Effects on psychological well‐being

Whether the negative effects of emotion suppression on psychological well‐being are applicable cross‐culturally is a long‐debated topic. The present study attempted to shed light on this debate, focusing on the effects of perceived emotion suppression and examining the psychological processes leading from perceived emotion suppression to lower psychological well‐being. We used a scale manipulation to lead 196 American and 213 Chinese participants to perceive themselves as having suppressed their emotions to a greater or lesser extent and then measured their life satisfaction. As expected, both the American and Chinese participants reported lower life satisfaction in the high‐suppression condition than in the low‐suppression condition; this negative effect was mediated by positive affect and moderated by self‐esteem. Specifically, perceived high emotion suppression decreased positive affect, which in turn led to lower well‐being. This effect was observed only for those with low self‐esteem, but the patterns and mechanisms were consistent cross‐culturally.     

Effects of suppressing neutral and obsession-like thoughts in normal subjects: beyond frequency

Recent cognitive-behavioral theories on obsessive-compulsive disorder (OCD) show that deliberate attempts to suppress intrusive and undesirable thoughts lie at the genesis of clinical obsessions. In this paper the results of an experimental study on the suppression of neutral and obsession-like thoughts in normal subjects are presented. Eighty-seven university students performed in three experimental periods: (1) base-line monitoring, (2) experimental instruction, and (3) monitoring. For each of these periods, the frequency of the occurrence of a "white bear" thought or a personally relevant intrusive thought was registered. Half of the subjects received instructions to suppress the target-thought in period 2, and the other half were instructed to only monitor the target-thought in each of the experimental periods. Several measures were also obtained before and after the experiment: annoyance caused by the intrusion, suppression effort, subjective success, and evaluative appraisals of the target-thought. The results showed neither immediate nor delayed frequency increases of the target thought. However, evidence was found that deliberate thought suppression efforts, regardless of their content, had greater negative consequences than did non suppression. These results are discussed in relation to the recent cognitive proposals about OCD.     

Unnoticed intrusions: Dissociations of meta-consciousness in thought suppression

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: (i) associated with stronger decoupling of attention from the environment, (ii) more likely to occur under cognitive load, (iii) more frequent for individuals with a desire to reconcile, and (iv) 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.     

Attempts to control unwanted thoughts in the night: development of the thought control questionnaire-insomnia revised (TCQI-R)

The attempted control of intrusive, uncontrollable thoughts has been implicated in the maintenance of a range of psychological disorders. The current paper describes the refinement of the Thought Control Questionnaire Insomnia (TCQI; Behav. Cogn. Psychoth. 29 (2001)) through its administration to a sample (n=385) including good sleepers and individuals with insomnia. Several items with poor psychometric properties were discarded, resulting in a 35-item revised TCQI. Factor analysis revealed six factors; aggressive suppression, cognitive distraction, reappraisal, social avoidance, behavioural distraction, and worry. The attempted management of unwanted thoughts was compared across individuals with insomnia and good sleepers, and the impact of these strategies on sleep quality, anxiety and depression was investigated. With the exception of cognitive distraction, individuals with insomnia, relative to good sleepers, more frequently used every thought control strategy. The strategies of aggressive suppression and worry, in particular, appeared to be unhelpful, with the use of these strategies predicting sleep impairment, anxiety and depression. The strategy of cognitive distraction appeared to be helpful, with the use of this strategy predicting better sleep quality.     

Learning By Tracing Worked Examples

Cognitive load theorists have only recently begun to test the role of the body in learning. Tracing the index finger over the surface of instructions while reading, an embodied pedagogy based on Montessori's sandpaper letters, may hold substantial promise for learning by reducing cognitive load. Two experiments tested whether students who traced their index fingers against paper‐based worked example instructions in triangle geometry (Experiment 1; N = 52) and order of operations (Experiment 2; N = 54) would perform better on a subsequent test than students who only studied the materials visually. Students in the tracing condition outperformed the non‐tracing condition on transfer problems in both Experiment 1 (d = .78) and Experiment 1 (d = .50), but hypotheses regarding self‐reports of cognitive load during testing were not supported. Implications for research and practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Ostracism Reduces Reliance on Poor Advice from Others during Decision Making

Decision making is rarely context‐free, and often, both social information and non‐social information are weighed into one's decisions. Incorporating information into a decision can be influenced by previous experiences. Ostracism has extensive effects, including taxing cognitive resources and increasing social monitoring. In decision making situations, individuals are often faced with both objective and social information and must choose which information to include or filter out. How will ostracism affect the reliance on objective and social information during decision making? Participants (N = 245) in Experiment 1 were randomly assigned to be included or ostracized in a standardized, group task. They then performed a dynamic decision making task that involved the presentation of either non‐social (i.e. biased reward feedback) or social (i.e., poor advice from a previous participant) misleading information. In Experiment 2, participants (N = 105) completed either the ostracism non‐social condition or social misleading information condition with explicit instructions stating that the advice given was from an individual who did not partake in the group task. Ostracized individuals relied more on non‐social misleading information and performed worse than included individuals. However, ostracized individuals discounted misleading social information and outperformed included individuals. Results of Experiment 2 replicated the findings of Experiment 1. Across two experiments, ostracized individuals were more critical of advice from others, both individuals who may have ostracized them and unrelated individuals. In other words, compared with included individuals, ostracized individuals underweighted advice from another individual but overweighed non‐social information during decision making. We conclude that when deceptive objective information is present, ostracism results in disadvantageous decision making. Copyright © 2015 John Wiley & Sons, Ltd.     

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

Busy perceivers and ineffective suppression goals: a critical role for distracter thoughts

With limited cognitive resources, suppressing thoughts can be ineffective. The detrimental effects of cognitive load on suppression have typically been attributed to increased accessibility of avoided thoughts. However, little research has examined distracter thoughts and their contribution to these effects. In three studies, participants pursued suppression goals related to social judgments (e.g., avoid negative thoughts about a target's performance) with sufficient or diminished cognitive resources. Compared to suppressors not under cognitive load, suppressors under load drew more negative social inferences when pursuing a negative suppression goal and more positive inferences under a positive suppression goal; load did not similarly disrupt a concentration goal (i.e., focus on positive thoughts). Across studies, load reduced high-quality oppositely valenced distracter thoughts, and these distracter thoughts mediated the detrimental effects of load on social inferences. The discussion focuses on mechanisms underlying the effects of load on suppression, implications, and future directions for research on ironic processes.
