This case study, which incorporates one experiment and a naturalistic investigation, examines unusual phenomena associated with a transcendent human experience, in the broad category of near-death and nature mysticism type experiences. The human experience is documented predominantly through spoken normal recall, as well as written and clinical hyp...

Several studies support the relevance of psychological and psychosocial factors in the assessment and management of chronic musculoskeletal pain disorders, including temporomandibular pain disorders (TMDs). The aim of this study was to re-evaluate subtyping approach used in an earlier study (TI Suvinen, KR Hanes, JA Gerschman, PC Reade. J Orofac Pa...

Salvia divinorum is a perennial Mexican herb from the labiate (mint) family (Epling & Jativa, 1962) that has a history of use chiefly for the initiation and facilitation of shamanic practice among such peoples as the Mazatec Indians of the Sierra Mazateca region of Oaxaca, Mexico, and possibly by earlier human civilizations (Johnson, 1939; Wasson,...

Fourteen patients with body dysmorphic disorder (BDD) were assessed with neuropsychological measures, including tests of executive, mnestic, and motor functions. Performance in these patients was compared to 10 patients with obsessive-compulsive disorder (OCD), 14 patients with schizophrenia, and 24 normal controls. Findings indicated normal perfor...

The present study considered predictors of the outcome of treatment for temporomandibular pain dysfunction disorder (TMPD). Thirty-seven patients were assessed with objective and self-report measures of physiological and psychosocial aspects of this disorder at initial assessment and at 6-month follow-up subsequent to conservative physical therapy....

This study presents an approach to the classification of temporomandibular disorders (TMD) based on acknowledgement of the interaction of physical, psychologic, and social factors using a multidimensional instrument that has been previously validated. The psychometric properties of this instrument were reevaluated in 140 women with TMD. Multidimens...

Neuropsychological performance in 20 chronic schizophrenic patients was contrasted to 25 Parkinson's disease, 12 Huntington's disease patients and 26 normal controls on measures shown to be sensitive to subcortical dysfunction. Some overlap was observed in the performance of the schizophrenic and basal ganglia groups on tasks of executive and mnest...

The current paper assessed bradyphrenia, or slowed thinking, in patients with Parkinson's disease, Huntington's disease, and schizophrenia using a modified planning measure designed to maximise the demands on cognitive processing. Findings indicated normal performance in schizophrenia but prolonged thinking time in Parkinson's disease and, to a les...

The current study evaluated the discriminant validity and homogeneity of category fluency, Stroop interference, and planning measures of executive dysfunction and introduced a new measure of planning behavior. We compared performance of patients with schizophrenia, Parkinson's disease, and Huntington's disease, which are disorders associated with s...

Two new tasks designed to individualize and assess aspects of cognitive flexibility and complex integration were administered to patients with schizophrenia (n = 16), Parkinson's disease (PD; n = 25) and Huntington's disease (HD; n = 12). Findings indicated impaired performance in the schizophrenic and HD groups on components of solution fluency, r...

Verbal fluency was compared in Huntington's disease (n=12), Parkinson's disease (n=25) and schizophrenia (n=18) with a series of fluency tasks evaluating the effects on productivity of cuing with subordinate categories and alternation between fluency probes. Findings indicated reduced output in the patient groups across all tasks consistent with a...
