Although rumination has been proposed to play an important role in the creation of hallucinations, direct empirical tests of this proposal have not yet been performed. Employing a distinction between ruminative and reflective self-consciousness, we set out to test a new model of the relations among rumination, reflection, intrusive thoughts, thought suppression, social anxiety, and hallucinatio...

Intrusive memory experiences (IMEs) are a common symptom of post-traumatic stress disorder (PTSD). Sensory perceptions of IMEs in the PTSD context vary substantially. The present research examined 20 patients with a single trauma, 20 re-traumatized patients and 80 Holocaust-traumatized patients who suffered from PTSD. Our results revealed significant differences in IME frequency based on the ty...

This study examined the association between self-evaluative intrusive thoughts and performance in an Internet search task. Participants performed an information search on the Internet, completed the Cognitive Interference Questionnaire [CIQ; Journal of Consulting & Clinical Psychology, 46 (1978), 102], and then responded to a self-assessment questionnaire on their search performance. Participan...

Attention Deficit/Hyperactivity Disorder (ADHD) is associated with deficient motor and cognitive inhibitory mechanisms. The aim of this article is to examine two symptoms associated with cognitive disinhibition, namely: intrusive unwanted thoughts, worrisome thoughts and their suppression. Thirty-seven college students diagnosed with ADHD and 23 healthy college students were compared on the Dis...

This paper proposes statistical feature extraction methods combined with artificial intelligence (AI) approaches for fault locations in non-intrusive single-line-to-ground fault (SLGF) detection of low voltage distribution systems. The input features of the AI algorithms are extracted using statistical moment transformation for reducing the dimensions of the power signature inputs measured by u...

The study and characterization of user behavior in the context of human computer interaction allows us to improve the design of interactive applications. Using certain sensors to analyze user behavior such as an eye tracking system can be intrusive and uncomfortable. In this paper, we report on an experiment to determine the minimum field of view that permits the user to perform an effective se...

Non-intrusive load monitoring (NILM) identifies used appliances in a total power load according to their individual load characteristics. In this paper we propose an evolutionary optimization algorithm to identify appliances, which are modeled as on/off appliances. We evaluate our proposed evolutionary optimization by simulation with Matlab, where we use a random total load and randomly generat...

The main aims of this huge unprecedented multi-national study of intrusive thoughts were to ascertain the prevalence of the phenomenon, determine whether it is dimensional or categorical in nature, and the extent to which the thoughts reflect cultural differences. The answers to the first two questions were clear. Intrusive thoughts are extraordinarily prevalent and dimensional in nature. There...

Nuss procedure is that recurrence is very rare. Most of our recurrences were in the first 10-year experience, and when you really look at the data, all of them were in the younger kids. Now, those were also the kids in whom we were taking the bars out before 2 years, and we really only had two recurrences in the last 1000 patients, and all of those were, again, in kids less than 13 years old. T...

Three experiments indexed the effect of various concurrent tasks, while watching a traumatic film, on intrusive memory development. Hypotheses were based on the dual-representation theory of posttraumatic stress disorder (C. R. Brewin, T. Dalgleish, & S. Joseph, 1996). Nonclinical participants viewed a trauma film under various encoding conditions and recorded any spontaneous intrusive memories...
