In this work, we present an experimental study of dissociative excitation of CH4 utilizing a crossed electron molecular beam experiment. Methane was excited by nearly monochromatic electrons generated by a trochoidal electron monochromator. The dissociative products were identified on the basis of the emission spectra in the ultraviolet–visible (UV/VIS) spectral range. The excitation functions ...

The adsorption properties of CO and H2 on iron-based catalyst with addition of Zr and Ni were investigated using temperature programmed desorption process. It was found that on the carburized iron-based catalysts, molecular state and dissociative state CO existed together. The addition of Zr was preferential for the molecular state adsorption of CO on iron-based catalyst and the presence of Ni ...

The fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, ) contains a dissociative subtype for posttraumatic stress disorder (PTSD) characterized by significant depersonalization and derealization. In this study the PTSD dissociative subtype was examined using latent profile analysis in a sample of 541 trauma-exposed college students. ...

Two longitudinal attachment studies of families at social risk have now followed their cohorts of infants to late adolescence. Several key findings have emerged related to outcomes of interest to psychoanalysts. First, data from both studies indicate that disorganized attachment behaviors in infancy are important precursors of later dissociative symptomatology. Second, this early vulnerability ...

INTRODUCTION The utilization of the post-traumatic stress disorder (PTSD) diagnostic spectrum is currently being debated to categorize psychological adjustment in cancer patients. The aims of this study were to: (1) evaluate the presence of cancer-related traumatic dissociative symptomatology in a sample of cancer patients; (2) examine the correlation of cancer-related dissociation and sociodem...

Dissociative disorders, including multiple personality disorder and allied forms of dissociative disorder not othenuise specified, were encountered in 20 practicing psychotherapists. Detailed reportage is precluded by considerations of confidentiality. Selected topics with regard to their professional functioning, diagnosis, phenomenology, treatment, and prognosis will be discussed. Multiple pe...

Different hypotheses exist for the relationship among trauma, dissociation, and recovered memory. According to one view, recovered memory results from dissociation that a survivor adopts as a defense mechanism during a traumatizing event to avoid emotional pain. From this perspective, trauma is a necessary antecedent to relate dissociative symptoms with recovered memory. Another view emphasizes...

We use velocity map imaging of photoelectrons in coincidence with molecular cations to determine which ionic states are populated via strong field ionisation, and whether the ionisation to excited ionic states proceeds indirectly via the ground ionic state or directly from the neutral. We carry out measurements on a series of molecules that have different energy gaps between the ground ionic st...

This paper provides an historical perspective regarding the role of dissociation in the development of both etiologic theory and treatment paradigms for schizophrenia. References to the concept of dissociation are drawn from classic writings on dementia praecox, and from Bleuler's (1911) original conception of schizophrenia as a splitting" of the personality. An accurate diagnostic distinction ...

Nonclinical studies found that dissociative experiences are intimately linked to a trait known as fantasy proneness. We examined the links among dissociative symptoms, fantasy proneness, and impulsivity in psychiatric outpatients. Our sample consisted of 22 patients with schizophrenia, 20 patients with a diagnosis of borderline personality disorder, and 19 patients with a major depressive disor...
