Attachment-related strategies during thought suppression: ironic rebounds and vulnerable self-representations

The authors conducted 2 studies of attachment-related variations in thought suppression. Participants were asked, or not asked, to suppress thoughts about a relationship breakup and then to perform a Stroop task under high or low cognitive load. The dependent variables were the rebound, of previously suppressed separation-related thoughts (Study 1) and the accessibility of self-traits (Study 2). Under low cognitive load, avoidant individuals did not show any rebound of separation-related thoughts and activated positive self-representations. Under high cognitive load, avoidant participants failed to suppress thoughts of separation and were more likely to activate negative self-representations. Attachment anxiety was associated with high activation of negative self-representations and unremitting separation-related thoughts. The results are discussed in terms of the hidden vulnerabilities of avoidant individuals.     

Tracking the train of thought from the laboratory into everyday life: An experience-sampling study of mind wandering across controlled and ecological contexts

In an experience-sampling study that bridged laboratory, ecological, and individual-differences approaches to mind-wandering research, 72 subjects completed an executive-control task with periodic thought probes (reported by McVay & Kane, 2009) and then carried PDAs for a week that signaled them eight times daily to report immediately whether their thoughts were off task. Subjects who reported more mind wandering during the laboratory task endorsed more mind-wandering experiences during everyday life (and were more likely to report worries as off-task thought content). We also conceptually replicated laboratory findings that mind wandering predicts task performance: Subjects rated their daily-life performance to be impaired when they reported off-task thoughts, with greatest impairment when subjects’ mind wandering lacked metaconsciousness. The propensity to mind wander appears to be a stable cognitive characteristic and seems to predict performance difficulties in daily life, just as it does in the laboratory     

Organization of the Self-Concept and the Suppression of Self-Relevant Thoughts

The rebound effect associated with thought suppression has been found following attempts at suppressing both novel stimuli and stereotypical thoughts. However, research examining the suppression of self-relevant thoughts has been less successful in demonstrating the rebound effect. A potential factor that has not yet been fully explored in research on thought suppression is how different types of distracter thoughts may influence the ability to suppress unwanted thoughts. One type of distracter that people may use while attempting to suppress unwanted self-relevant thoughts is information related to other aspects of their lives. To the extent that these other aspects are more likely to be associated in memory with the unwanted thoughts, rebound should be more likely to occur. Thus, we expected and found that people lower in self-complexity (i.e., those with fewer self-aspects that are more interrelated with one another) revealed greater rebound following thought suppression that involved self-relevant distracting thoughts than did people greater in self-complexity. Implications of these findings for thought suppression, self-complexity, depression, and the experience of affect are discussed.     

Expanding the topography of social anxiety. An experience-sampling assessment of positive emotions, positive events, and emotion suppression

The relation between social anxiety and hedonic activity remains poorly understood. From a self-regulatory perspective, we hypothesized that socially anxious individuals experience diminished positive experiences and events on days when they are unable to manage socially anxious feelings adequately. In this 21-day experience-sampling study, we constructed daily measures of social anxiety and emotion regulation. Greater dispositional social anxiety was associated with less positive affect and fewer positive events in everyday life. Among individuals defined as socially anxious from their scores on a global self-report measure of social anxiety, the number of positive events was lowest on days when they both were more socially anxious and tended to suppress emotions and highest on days when they were less socially anxious and more accepting of emotional experiences. Irrespective of dispositional social anxiety, participants reported the most intense positive emotions on the days when they were both least socially anxious and most accepting of emotional experiences. Possible clinical implications are discussed.     

Why are some obsessions more upsetting than others?

Little is known about why certain obsessional thoughts are more upsetting than others for people with obsessive compulsive disorder (OCD). Obsessional thought content often seems arbitrary to sufferers. The current study examined three possible reasons why particular thoughts would be especially upsetting for individuals, based on suggestions put forth by cognitive theories of obsessional thoughts. Twenty-eight individuals with a principal diagnosis of OCD completed questionnaires and interviews at two different periods of time on (1) their most upsetting current obsession and (2) their least upsetting current obsession. Results suggested that more upsetting obsessions were evaluated as more meaningful or significant than less upsetting obsessions, and more upsetting obsessions contradicted valued aspects of the self to a greater degree. All examples of current obsessions, both most and least upsetting, arose in the context of life concerns or issues. Results support cognitive theories in that the strength and nature of appraisal appears to be linked with the distress associated with a thought, and more upsetting thoughts are those that have implications for a person's sense of self.     

Separating sustained from transient aspects of cognitive control during thought suppression

Cognitive theories of how people regulate their thoughts have suggested the involvement of two control processes that occur over different time courses. These cognitive accounts parallel recent neural models of executive control, which suggest that the prefrontal cortex (PFC) mediates sustained changes in the allocation of control processes, whereas the anterior cingulate cortex (ACC) relays a transient need for additional control. Combining these cognitive and neural models of control, we used recently developed analysis techniques to distinguish transient from sustained changes in brain activation while subjects attempted to suppress an unwanted thought. Results were consistent with both models: Dorsolateral PFC demonstrated sustained increases in activation during attempts at thought suppression, whereas bilateral ACC demonstrated transient increases associated with occurrences of unwanted thoughts. These data support proposals regarding the different contributions made by the PFC and ACC to executive control and provide initial neuroimaging support for dual-process models of how individuals regulate their thoughts.     

Thought suppression and its effects on thought frequency, appraisal and mood state in individuals with obsessive-compulsive disorder

Leading models of obsessive-compulsive disorder (OCD) implicate thought suppression as a key factor in the escalation and persistence of the disorder. This experiment examined the effects of suppression on the frequency of obsessional thoughts in 50 individuals with a primary diagnosis of OCD, and also investigated the effects of participants' appraisals regarding their failures in thought control on distress about intrusive thoughts and on mood. Participants' most upsetting obsessional thought was primed and they then monitored its occurrence over two 4-min intervals. In the first interval, half of the participants were instructed to suppress their obsessional thought and half were instructed not to suppress any thoughts. In the second interval, all participants were given the 'Do Not Suppress' instructions. Participants rated their suppression effort and discomfort over thought occurrences after each interval and recorded their appraisals of thought recurrences during the first interval. Mood state was then reassessed. No ironic effect of suppression on frequency was noted. However, negative appraisals of thought recurrences were associated with more discomfort over thought occurrences and more negative mood at Time 2. These findings suggest that interpretations regarding failures in thought control may be of central importance in understanding obsessional problems.     

Cognitive control of obsessional thoughts

A defining characteristic of obsessive-compulsive disorder (OCD) is unsuccessful suppression of unwanted thoughts. Recent evidence of individual differences in ability to control intrusive thoughts may inform our understanding of failures of cognitive control associated with OCD symptomatology. The current study investigated characteristics of cognitive style that are potentially associated with OCD symptoms and may influence response to unwanted thoughts, including perceived ability to control thoughts and tendency to ruminate. Undergraduate students (N = 166) completed self-report measures of OCD symptoms, perceived thought control, and ruminative thinking. They were then presented with a distressing target thought and completed a standard thought suppression paradigm. Correlational results indicated that, controlling for anxiety and depression, OCD symptoms were positively associated with rumination and inversely associated with perceived thought control ability. In addition, OCD symptoms were associated with higher levels of distress and greater spontaneous efforts to suppress the target thought during a baseline period, while perceived thought control ability predicted frequency of target thoughts during suppression. Finally, results of the experimental manipulation confirmed that participants instructed to suppress experienced more intrusions during the recovery period. Clinical implications and future directions are discussed.     

For whom the mind wanders, and when: an experience-sampling study of working memory and executive control in daily life

An experience-sampling study of 124 undergraduates, pretested on complex memory-span tasks, examined the relation between working memory capacity (WMC) and the experience of mind wandering in daily life. Over 7 days, personal digital assistants signaled subjects eight times daily to report immediately whether their thoughts had wandered from their current activity, and to describe their psychological and physical context. WMC moderated the relation between mind wandering and activities' cognitive demand. During challenging activities requiring concentration and effort, higher-WMC subjects maintained on-task thoughts better, and mind-wandered less, than did lower-WMC subjects. The results were therefore consistent with theories of WMC emphasizing the role of executive attention and control processes in determining individual differences and their cognitive consequences.     

Motor control accuracy: a consequential probe of individual differences in emotion regulation

Two studies (total N = 147) sought to model emotion-regulation processes in cognitive-motoric terms. Hostile or nonhostile thoughts were primed and, immediately following, individuals held a joystick as accurately as possible on a presented visual target. Study 1 revealed that the activation of hostile thoughts impaired motor control at low levels of agreeableness but facilitated motor control at high levels of agreeableness, consistent with emotion-regulation views of this trait. Study 2 did not assess the trait of agreeableness but rather sought to determine whether better motor control following activated hostile thoughts would predict lesser reactivity to stressors in an experience-sampling protocol. It did, and relevant results are reported for daily anger, negative affect, and positive affect. In addition, and consistent with the agreeableness findings of Study 1, better motor control that follows hostile thoughts predicted greater empathy on high-stress days. Motor control probes of the present type thus appear consequential in understanding emotion-regulation processes and successes in emotion regulation.     

The gravity of unwanted thoughts: Asymmetric priming effects in thought suppression

An unwanted thought appears to be cued easily by reminders in the environment but often the thought itself seems to cue nothing more than the desire to eliminate it from consciousness. This unusual asymmetry in the way unwanted thoughts are linked to other thoughts was the focus of the present research. Participants who were asked to suppress a thought or to concentrate on it completed a task assessing the influence of priming on reaction time (RT) for word/non-word judgments. Results revealed that suppression under cognitive load produced asymmetric priming: Priming with the associate of a suppressed word speeded RT for the suppressed word, but priming with a suppressed word did not speed RT for associated words. These findings suggest that thought suppression induces an unusual form of cognitive accessibility in which movement of activation toward the suppressed thought from associates is facilitated but movement of activation away from the suppressed thought to associates is undermined.     

Thought suppression and self-injurious thoughts and behaviors

This study proposes and tests a theoretical model suggesting that the propensity to suppress unwanted thoughts is associated with an increased presence and frequency of self-injurious thoughts and behaviors (SITB). In the model, propensity to suppress unwanted thoughts is hypothesized to be a cognitive mediator of the relationship between emotional reactivity and SITB, and is expected to be related to the extent to which SITB is initiated to escape from aversive emotions. Results of this cross-sectional study of adolescents (N=87) revealed that the self-reported propensity to suppress unwanted thoughts is associated with the presence and frequency of non-suicidal self-injury (NSSI), suicidal ideation, and suicide attempts. Furthermore, thought suppression partially mediates the relationship between emotional reactivity and the frequency of NSSI and suicidal ideation. Finally, adolescents with a higher tendency to suppress unwanted thoughts report engaging in NSSI in order to reduce aversive emotions rather than for social communication. Results are discussed within the framework of the negative reinforcement function of SITB.     

Gesture offers insight into problem‐solving in adults and children

When asked to explain their solutions to a problem, both adults and children gesture as they talk. These gestures at times convey information that is not conveyed in speech and thus reveal thoughts that are distinct from those revealed in speech. In this study, we use the classic Tower of Hanoi puzzle to validate the claim that gesture and speech taken together can reflect the activation of two cognitive strategies within a single response. The Tower of Hanoi is a well‐studied puzzle, known to be most efficiently solved by activating subroutines at theoretically defined choice points. When asked to explain how they solved the Tower of Hanoi puzzle, both adults and children produced significantly more gesture‐speech mismatches—explanations in which speech conveyed one path and gesture another—at these theoretically defined choice points than they produced at non‐choice points. Even when the participants did not solve the problem efficiently, gesture could be used to indicate where the participants were deciding between alternative paths. Gesture can, thus, serve as a useful adjunct to speech when attempting to discover cognitive processes in problem‐solving.     

Cognitive defusion and self-relevant negative thoughts: examining the impact of a ninety year old technique

Cognitive defusion techniques are designed to reduce the functions of thoughts by altering the context in which they occur, rather than the attempting to alter the form, frequency, or situational sensitivity of the thoughts themselves. Applied technologies designed to produce cognitive defusion seem to lead to reductions in the believability of negative thoughts, but defusion techniques are generally only parts of complex packages and the role of defusion techniques per se is note yet known. The present study examined the impact of a cognitive defusion technique first described by Titchener nearly 90 years ago: rapidly repeating a single word. In series of eight single-case alternating treatment designs, this defusion technique was compared to a distraction task, and to a thought control task on reductions in the discomfort and believability of self-relevant negative thoughts. The cognitive defusion technique reduced both discomfort and believability more so than the comparison approaches. Control studies showed that the effect was probably not due to demand characteristics.     

The effects of suppressing a negative autobiographical memory on concurrent intrusions and subsequent autobiographical recall in dysphoria

Depressed individuals endeavor to suppress intrusive thoughts and memories as a form of mood control. Two predictions from this literature were examined. The 1st was that attempts to suppress a preselected negative memory during a stream-of-consciousness (SOC) task in dysphoric individuals, relative to a no-suppress condition, would lead to relatively speeded access to other negative but not positive memories on a subsequent cue-word recall task. No such effects were predicted for nondysphoric controls. The 2nd prediction was that, across all participants who were asked to suppress memories, higher levels of depressed mood would be associated with more intrusions of the to-be-suppressed memory during the SOC and that this association would be stronger than the comparable relation in participants who were not asked to suppress memories. Results support both predictions.     

Cognitive Load and the Equality Heuristic: A Two-Stage Model of Resource Overconsumption in Small Groups

Two studies were conducted to test a two-stage model of the psychological mechanisms underlying the overconsumption of scarce resources in small groups. The model proposes that members of groups sharing resources first anchor their consumption choices on an “equal-division” heuristic and then, given sufficient cognitive capacity, adjust their choices in a self-serving direction. The results from both studies support the model. The first study found that when faced with a common resource pool almost all group members expressed thoughts regarding equality; however, individuals with sufficient cognitive capacity requested more from the pool and expressed more task-relevant thoughts than individuals lacking the necessary cognitive resources. The second study provided additional support for the two-stage model by demonstrating that group members' cognitions occur in the order predicted by the model and by demonstrating that an individual difference, social value orientation, affects thought processes only when individuals are not experiencing high cognitive loads. Implications are discussed.     

A comparison of thought suppression to an acceptance-based technique in the management of personal intrusive thoughts: a controlled evaluation

Research suggests that suppressing unwanted thoughts is not possible, leads to a subsequent increase in frequency of the suppressed thoughts, and results in higher levels of distress. Because thought suppression may have negative effects, an alternative, acceptance-based approach has been proposed. The current paper reports the outcomes of two studies. Study I examined the relationships between two naturally occurring strategies of thought management (thought suppression and acceptance), symptoms of psychopathology, and experiences with personally relevant intrusive thoughts. Results showed that those who naturally suppress personally relevant intrusive thoughts have more, are more distressed by, and have a greater "urge to do something" about the thoughts, while those who are naturally more accepting of their intrusive thoughts are less obsessional, have lower levels of depression, and are less anxious. Study II compared three groups (thought suppression, acceptance, and monitor-only groups) on the frequency and distress associated with experiencing personally relevant intrusive thoughts. Results revealed that those instructed to suppress their personal intrusive thoughts were unable to do so and experienced an increased level of distress after suppression, whereas those instructed to use an acceptance-based strategy experienced a decrease in discomfort level (but not thought frequency) after having used such a strategy. These data offer initial evidence that acceptance may be a useful alternative to the suppression of personally relevant intrusive thoughts.     

Suicidal behavior among youth with severe emotional disturbance

The purpose of this study was to replicate an investigation of risk behaviors associated with suicidal behavior in public high school students, in a population of high school age youth with severe emotional disturbance (SED). Subjects for the study were clients of the South Carolina Continuum of Care (COC) (N=83). Information on suicidal thoughts and acts, aggressive behaviors, substance use and physical recklessness was gathered using a modified version of the self-report National Youth Risk Behavior Survey. Four percent of the youth reported seriously considering suicide, 8% reported planning how they would attempt suicide, 10% reported actually attempting suicide at least once, and 6% reported attempts requiring medical treatment Of the 13 youth who reported attempting suicide, four (31%) did not report planning an attempt. All suicidal behaviors except thoughts occurred more in girls than boys with SED. Alcohol and illicit drug use were associated with suicidal behavior, with larger odds ratios for attempts than for thoughts/plans. Youth with SED who use alcohol and illicit substances are particularly at risk of suicidal behavior. A high index of suspicion is appropriate when evaluating suicidal risk in girls with SED, especially in the presence of known alcohol or substance use.Continuum of Care for Emotionally Disturbed Children Division, S.

Cognitive effects of life stress and learned helplessness

Abstract Stressful life events and learned helplessness attributional styles have been shown to impact a variety of personal outcomes. This study examined how these factors influence two classes of cognitive behaviors: the occurrence of intrusive thoughts and performance in memory and verbal-spatial reasoning tasks. Negative life change and attributions for negative events predicted different types of cognitive responses. Individuals reporting higher levels of life stress were more likely to experience distracting thoughts that were unrelated to the current task, whereas individuals with learned helplessness attributional styles tended to have more worrisome thoughts about their task performance. In general, individuals reporting high levels of negative life stress tended to perform more poorly in tasks, whereas individuals with learned helplessness attributional styles tended to perform better than those who did not share this explanatory style. These results suggest that life stress and attributional style have important influecnes on cognitive processes, and that a learned helplessness attributional style can have beneficial effects on behavior in some situations.     

On bad mood and white bears: The effects of mood state on ability to suppress unwanted thoughts

Does temporary mood influence people's ability to engage in effective thought suppression? Based on past research on mental control and recent work on affective influences on social cognition, this experiment predicted and found that negative mood improved and positive mood impaired people's ability to suppress their thoughts when instructed not to think of a neutral concept, white bears. We also found clear evidence for ironic rebound effects: on a subsequent generative task, intrusions of the suppressed thought were greater in the negative than in the positive mood group. Participants received positive or negative feedback about performance on a supposed creativity task to induce positive or negative moods, and then engaged in two consecutive generative writing tasks, the first accompanied by instructions to suppress thoughts of white bears. Those in a negative group reported fewer “white bear” intrusions when attempting to suppress, but more “white bear” intrusions (an ironic rebound effect) in the subsequent task when the suppression instruction was lifted. The implications of these results for everyday tasks of mental control, and for recent affect–cognition theories are discussed.
