Harris, German and Mills (Children's use of counterfactual thinking in causal reasoning. Cognition, 61 (1996), 223± 259), following Mackie, argue that children make explicit use of counterfactual thinking in arriving at causal judgments. They showed that children as young as 3, in explaining simple mishap events, made reference to courses of action that a protagonist had rejected, when that cou...

Recently a novel technique has been published to augment traditional Branchand-Bound (B&B) while solving exactly a discrete optimization problem [Goldberg et al., 1997]. This technique is based on the negative thinking paradigm and has been applied to develop , a Unate Covering Problem (UCP) solver which reportedly was able to deal efficiently with some time-consuming benchmark problems. Howeve...

OBJECTIVES Repetitive speech phenomena are morphologically heterogeneous iterations of speech which have been described in several neurological disorders such as vascular dementia, progressive supranuclear palsy, Wilson's disease, and Parkinson's disease, and which are presently only poorly understood. The present, prospective study investigated repetitive speech phenomena in Parkinson's diseas...

BACKGROUND A growing body of evidence points to relationships between insomnia, negative affect, and paranoid thinking. However, studies are needed to examine (i) whether negative affect mediates the relation between insomnia and paranoid thinking, (ii) whether different types of insomnia exert different effects on paranoia, and (iii) to compare the impact of objective and self-reported sleepin...

Negative thinking is seen as an important mediating factor in the development of prolonged grief disorder (PGD), a syndrome encompassing debilitating symptoms of grief. No measure of specific grief related cognitions is available yet. Based on an adult measure of negative thinking in adults we developed a questionnaire for children, the Grief Cognitions Questionnaire for Children (GCQ-C). This ...

This is the first study to examine attentional control capacities in generalized anxiety disorder (GAD). GAD is characterized by uncontrollable worry. Individuals diagnosed with GAD and healthy participants (HPs) performed a random key-pressing task while thinking about a worrisome or a positive future event, to assess the extent to which attentional control resources are used by worry. Attenti...

Participants recalled either a negative academic or interpersonal experience, and the relations among counterfactual thinking, negative emotions, and attributions of blame and control were examined. Situational context effects on attribution, counterfactual thinking, and emotion were observed, indicating a greater tendency toward self-focused cognition and emotion in the academic context than i...
