SPAR (Speech-Pattern Algorithms and Representations) is the name given to The project is concerned with advanced speech analysis algorithms, and from the outset saw the need for a system for speech data management. The SPAR Speech Filing System (SFS) was developed to support the design and comparison of analysis algorithms, and to manage many different(More)
Literature that addresses the diagnosis of mental disorder in adolescents strongly suggests that it may not be possible to do so. Schizophrenic thinking, in particular, has been seen as generally characteristic of adolescents. Making judgments of specific responses from the Rorschach, the WAIS, and the WIST, 10 expert clinicians were able to make judgments(More)
Two studies of conceptual rule-learning by 36 hospitalized psychiatric patients revealed that (a) while all were clinically diagnosed as schizophrenic, they differed widely in their ability to discover abstract rules; (b) the Whitaker Index of Schizophrenic Thinking (WIST) strongly predicted the patients' ability to learn and to apply a conceptual rule; and(More)
Three studies investigated developmental changes in facial expression processing, between 3 years-of-age and adulthood. For adults and older children, the addition of sunglasses to upright faces caused an equivalent decrement in performance to face inversion. However, younger children showed better classification of expressions of faces wearing sunglasses(More)
Examined in detail the performance of 36 hospitalized male schizophrenics on the Whitaker Index of Schizophrenic Thinking (WIST). Results indicated two interesting phenomena. First, the performance of patients with the highest level of cognitive deficit approached a random level of responding with respect to both the type of error made and the propensity to(More)
Individuals with autism spectrum disorder (ASD) often show atypical processing of facial expressions, which may result from visual stress. In the current study, children with ASD and matched controls judged which member of a pair of faces displayed the more intense emotion. Both faces showed anger, disgust, fear, happiness, sadness or surprise but to(More)
This study reports a study of Spanish translation of Form A of the Whitaker Index of Schizophrenic Thinking (WIST) administered to 104 Mexican subjects: 40 schizophrenic (20 acute and 20 chronic) and 64 nonschizophrenic (10 nonschizophrenic hospitalized, 10 alcoholics, and 44 normals). A multiple regression analysis was carried out in order to evaluate the(More)
Developed the present study in conjunction with a project that evaluated the psychiatric diagnosis of schizophrenia (Landmark, 1982; Landmark & Leslie, 1982). This design, which included 13 different interview systems for diagnosing schizophrenic disorders, allowed for an in-depth analysis of the Whitaker Index of Schizophrenic Thinking (WIST). Eighty-five(More)
The Spanish translation of Form A of the Whitaker Index of Schizophrenic Thinking (WIST) was administered to 50 schizophrenic (25 acute; 25 chronic) and 50 (25 = depressives; 25 = normals) nonschizophrenic residents of the Commonwealth of Puerto Rico. Results suggest that this translation effectively discriminated between schizophrenics and(More)
