Information Distortion and Voting Choices: The Origins and Effects of Factual Beliefs in Initiative Elections

To account for voter decision making in initiative elections, we integrate theory and research on public opinion, misinformation, and motivated reasoning. Heuristic and motivated reasoning literatures suggest that voters' preexisting values interact with political sophistication such that politically knowledgeable voters develop systematically distorted empirical beliefs relevant to the initiatives on their ballots. These beliefs, in turn, can predict voting preferences even after controlling for underlying values, regardless of one's political sophistication. These hypotheses were tested using a 2003 voter survey conducted prior to a statewide initiative election that repealed a workplace safety regulation. Results showed that only those voters knowledgeable of key endorsements had initiative-specific beliefs that lined up with their underlying antiregulation values. Also, voters' empirical beliefs had an effect on initiative support even after controlling for prior values, and political sophistication did not moderate this effect.     

Change in metacognitions predicts outcome in obsessive–compulsive disorder patients undergoing treatment with exposure and response prevention

Wells' (Wells, A. (1997). Cognitive therapy of anxiety disorders: a practice manual and conceptual guide. Chichester, UK: Wiley) metacognitive model of obsessive–compulsive disorder (OCD) predicts that metacognitions must change in order for psychological treatment to be effective. The aim of this study was to explore: (1) if metacognitions change in patients undergoing exposure treatment for OCD; (2) to determine the extent to which cognitive and metacognitive change predicts symptom improvement and recovery. The sample consisted of 83 outpatients with a diagnosis of OCD who completed exposure and response prevention treatment. The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS), the Metacognitions Questionnaire (MCQ-30) and the Obsessive Beliefs Questionnaire (OBQ-44) were administered before treatment, after treatment, and at 12-month follow-up. Treatment resulted in significant changes in symptoms, metacognition score, responsibility and perfectionism. Regression analysis using post-treatment Y-BOCS as the dependent variable indicated that when the overlap between predictors was controlled for, only changes in metacognition were significant. Changes in metacognitions explained 22% of the variance in symptoms at post-treatment when controlling for pre-treatment symptoms and changes in mood. A further regression revealed that two MCQ-30 subscales made individual contributions. The patients had significantly higher scores compared to community controls on the MCQ-30. Patients who achieved clinical significant change had lower scores on the MCQ-30 compared to patients who did not change. The results did not change significantly from post-treatment to follow-up assessment. These findings provide further support for the importance of metacognitions in treating OCD.     

Facial Composite Production by Eyewitnesses

ABSTRACT— The creation of facial images by eyewitnesses using composite-production systems can be important for the investigation of crimes when the identity of the perpetrator is at issue. Despite technological advances, research indicates that composite-production systems produce poor likenesses of intended faces, even familiar faces. Furthermore, producing a composite appears to harm later recognition performance. Although morphing composites from multiple witnesses helps, likeness is still limited. The problem might stem from a mismatch between how faces are represented in memory (holistically) and how composite systems attempt to retrieve the memories (at the feature level). New methods of face recall involving judgments of whole faces hold greater promise.     

Intrusive images and memories in major depression

Individuals with current major depression were interviewed to investigate the prevalence of distressing intrusive mental imagery among depressed patients and study the phenomenology of these intrusions. Of the 39 currently depressed patients, 17 experienced some form of repetitive intrusive imagery (i.e., either an intrusive memory or image), with intrusive memories being more common than images. The intrusive imagery was experienced as highly uncontrollable and interfered significantly with patients' everyday lives. The intrusions were experienced with a sense of 'nowness', as well as physical and emotional re-experiencing. Despite high levels of re-experiencing, levels of dissociation were very low. The intrusive imagery was in some patients part of a wider network of key defining autobiographical memories, consistent with the idea that it is likely to play a significant role in maintaining the patient's depressive mood. Interventions targeting these intrusions could potentially result in a positive shift in depressed mood.     

Belief disconfirmation versus habituation approaches to situational exposure in panic disorder with agoraphobia: a pilot study

Exposure therapy and cognitive behaviour therapy (CBT) are both effective in the treatment of panic disorder with agoraphobia. Cognitive theories suggest that the way in which exposure to avoided situations is implemented in either treatment may be crucial. In particular, it is suggested that clinical improvement will be greatest if opportunities for disconfirmation of feared catastrophes are maximized. In a small pilot study, 16 patients with panic disorder and (moderate or severe) agoraphobia were randomly allocated to either habituation based exposure therapy (HBET) or exposure planned as a belief disconfirmation strategy and accompanied by dropping of safety-seeking behaviours. Both treatments were brief (total of 3.25 h of exposure) and were similar in terms of expectancy of change. Patients in the CBT condition showed significantly greater improvements in self-report measures of anxiety, panic and situational avoidance. They also completed significantly more steps in a standardized behavioural walk, during which they experienced significantly less anxiety. The controlled effect sizes for CBT were substantial (range 1.7-2.7), which suggests it may be a particularly efficient way of managing therapeutic exposure to feared situations in panic disorder with agoraphobia. Further research is needed to clarify the mechanism of change involved.     

Cognition About Cognition: Metacognitive Therapy and Change in Generalized Anxiety Disorder and Social Phobia

Metacognitive theory and therapy views the persistence of negative beliefs and thoughts as a result of metacognitions controlling cognition. This paper describes, with reference to the treatment of generalized anxiety disorder (GAD) and social phobia, how metacognition contributes to cognitive stability and to change. Metacognitive therapy offers a level of formulation and intervention that does not focus predominantly on challenging the content of negative thoughts and beliefs that are emphasized in traditional cognitive therapy. The focus of treatment in GAD is on erroneous beliefs about worry and unhelpful mental regulation strategies. In treating social phobia, a greater emphasis is placed on modifying attention and worry processes and on configuring processing during and after behavioral experiments.     

Heterogeneity in ADHD: Neurocognitive predictors of peer,family, and academic functioning

Childhood attention-deficit/hyperactivity disorder (ADHD) is associated with impairments in peer, family, and academic functioning. Although impairment is required for diagnosis, children with ADHD vary significantly in the areas in which they demonstrate clinically significant impairment. However, relatively little is known about the mechanisms and processes underlying these individual differences. The current study examined neurocognitive predictors of heterogeneity in peer, family, and academic functioning in a well-defined sample of 44 children with ADHD aged 8–13 years (M = 10.31, SD = 1.42; 31 boys, 13 girls; 81% Caucasian). Reliable change analysis indicated that 98% of the sample demonstrated objectively-defined impairment on at least one assessed outcome measure; 65% were impaired in two or all three areas of functioning. ADHD children with quantifiable deficits in academic success and family functioning performed worse on tests of working memory (d = 0.68 to 1.09), whereas children with impaired parent-reported social functioning demonstrated slower processing speed (d = 0.53). Dimensional analyses identified additional predictors of peer, family, and academic functioning. Working memory abilities were associated with individual differences in all three functional domains, processing speed predicted social functioning, and inhibitory control predicted family functioning. These results add to a growing literature implicating neurocognitive abilities not only in explaining behavioral differences between ADHD and non-ADHD groups, but also in the substantial heterogeneity in ecologically-valid functional outcomes associated with the disorder.     

Negative Emotions and Alcohol Use Initiation in High-Risk Boys: The Moderating Effect of Good Inhibitory Control

Studies on the relation between negative affect and later alcohol use have provided mixed results. Because definitions of negative affect often include diverse emotions, researchers have begun to dismantle this higher-order construct in an attempt to explain these inconsistent findings. More recent evidence also indicates that good inhibitory control may moderate the relation between negative emotions and alcohol use. The current longitudinal investigation examined the independent relation between three components of negative affect (i.e., depressed mood, fear, and anger) and alcohol use initiation in a sample of aggressive boys. The moderating effect of good inhibitory control was also examined. Results indicated that increased anger and decreased fearfulness are associated with an increased risk for alcohol use initiation only for boys with moderate to low levels of inhibitory control. However, depressed mood predicted alcohol use initiation for boys with good inhibitory control. The potential implications for substance use prevention efforts are discussed.     

A comparison of metacognitions in patients with hallucinations,delusions, panic disorder,and non-patient controls

This study tested the hypothesis that metacognitions are a general vulnerability factor for psychological disorder. It was predicted that patients with psychosis (hallucinations or delusions), and patients with panic disorder would score higher than non-patients on measures of metacognition. Moreover, it was hypothesised that patients showing most dysregulation of thinking (voice-hearers) would endorse significantly higher metacognition scores than individuals in the other groups. The Meta-Cognitions Questionnaire (MCQ: ) was administered to patients who met DSM-IV criteria for schizophrenia spectrum disorders with auditory hallucinations, patients who met DSM-IV criteria for schizophrenia spectrum disorders with persecutory delusions, patients who met DSM-IV criteria for panic disorder and non-patients. The results showed that psychotic patients who experience auditory hallucinations tended to exhibit higher levels of dysfunctional metacognitive beliefs than other patient groups, scoring significantly higher than at least two of the three control groups on positive beliefs about worry, negative beliefs about uncontrollability and danger, cognitive confidence and negative beliefs including superstition, punishment and responsibility. It was also found that the metacognitive beliefs of patients with persecutory delusions and panic patients were often similar to each other, and elevated in comparison to non-patients, suggesting that such beliefs are generic vulnerability factors. The theoretical and clinical implications of these findings are discussed.
