INTERMITTENT REGRESSIONS IN A SERIAL AFTERIMAGE EXPERIMENT AS SIGNS OF SCHIZOPHRENIA

S mith G. J. W., R uuth E., F ranzén G. & S jöholm L. Intermittent regressions in a serial afterimage experiment as signs of schizophrenia. Scand. J. Psychol ., 1972 , 13 , 27 33.—A group of 35 young patients suspected of schizophrenia were tested in a serial afterimage (AI) experiment and were also rated on the Rockland-Pollin scale. Subjects with high psychotic scores showed one or more regressions to immature (size-constant, positive, physiognomic) images in their Al serials, images typical of children who cannot clearly distinguish their Ails as subjective phenomena distinct from the outside world. The Al test thus indicates schizophrenics to be characterized by intermittent withdrawal into a world of experiencing the self and non-self as not clearly distinguished. Regressions were rare in two control groups.     

Projected afterimages after manipulation of cognitive schemes in children.

Telling one group of subjects that afterimages are a physical reality largely independent of the observer and another group that afterimages are projected by the subject himself, it was predicted that the afterimages in these groups would differ. In all 10 pairs of nine-year-old children, matched with respect to cognitive maturity, the subject getting the former instruction reported more size-constant and/or positive afterimages than the subject getting the latter instruction.     

Veridical and false memory for scenic material in posttraumatic stress disorder

The question whether memory aberrations in posttraumatic stress disorder (PTSD) also manifest as an increased production of false memories is important for both theoretical and practical reasons, but is yet unsolved. Therefore, for the present study we investigated veridical and false recognition in PTSD with a new scenic variant of the Deese-Roediger-McDermott (DRM) paradigm, which was administered to traumatized individuals with PTSD (n=32), traumatized individuals without PTSD (n=30), and non-traumatized controls (n=30). The PTSD group neither produced higher rates of false memories nor expressed more confidence in errors, but did show inferior memory sensitivity. Whereas depressive symptoms did not correlate with veridical nor false recognition, state dissociation was positively associated with false memories.

How to tell a happy person: Accuracy of subjective well-being perception from texts

Motivation and Emotion - Although perceptions of subjective well-being (SWB) in unacquainted others have been shown to play a major role in impression formation, little is known about how accurate...     

A model for the study of research and education in a transdisciplinary context

In an evaluation project at the Goteborg University, we have looked at the relationship between individual and collective production of knowledge within the Health sciences in order to facilitate a common ground for a Academy of Health Sciences. We found obstacles for developing an environment which could stimulate multilateral co-operation and creativity. Some of these obstacles have their root in the different cultural backgrounds indicated in the analysis and makes it difficult to find common aims and strategies. The Model used makes the organizations’ activities visible and encouraging transdisciplinary contacts and improve organizational, structural and ideological decision making emanating from overall policies of the boards concerned.     

Supervisory countertransferences and impingements in evaluating readiness for graduation: Always present,routinely under‐recognized

Utilizing detailed, in‐depth material from supervisory hours from around the world (explored in End of Training Evaluation groups), this paper shows that supervisors are subject to multiple, diverse and, at times, ongoing intense countertransferences and impingements on their ability to evaluate candidates’ progress. Multiple external and internal sources of these impingements are explored. It is suggested that supervisory countertransferences and their manifestation in parallel enactments remain under‐recognized, their impact underappreciated, and the information they contain underutilized. It is argued that the recognition, containment, and effective use of the parallel process phenomena and supervisory countertransferences are essential in order to evaluate candidates’ progression and readiness to graduate. Common signals of such entanglements in the supervisor's evaluative function are identified. Three remedies, each of which provides a ‘third,’ are offered to assist supervisors in making effective use of their countertransference: self‐supervision, consultation, and institutional correctives.     

Cognitive Processes Underlying Observational Learning of Motor Skills

There is evidence indicating that an individual can learn a motor skill by observing a model practising it. In the present study we wanted to determine whether observation would permit one to learn the relative timing pattern required to perform a new motor skill. Also, we wanted to determine the joint effects of observation and of physical practice on the learning of that relative timing pattern. Finally, we were interested in finding whether there was an optimal type of model, advanced or beginner, which would lead better to observational learning. Data from two experiments indicated that observation of either a beginner or an advanced model resulted in modest learning of a constrained relative timing pattern. Observation also resulted in significant parameterization learning. However, a combination of observation followed by physical practice resulted in significant learning of the constrained relative timing pattern. These results suggest that observation engages one in cognitive processes similar to those occurring during physical practice.
