Complexity,information and time

Evolution proceeds in time. Time is experienced as change only, predominantly irreversible change. Measuring change in the form of information growth it is possible to define a measure for the amount of time produced during information increase. Systems creating information contribute to the generation of time. To be able to create information, a system has to be highly complex. The more complex a system is, the more it can contribute to generation of time. The rate of time generation is determined by the capability of the system to gain information. Complexity, information accumulation, and time generation are therefore synonyms.     

Opfer-überzeugungen

The public interest in ??new?? clinical symptoms is described exemplified by burnout, mobbing and trauma. In the background self-explanations by patients as well as interests of therapists can be recognized. Both can be understood as an expression of subconsciously reflected contemporary convictions. Post-traumatic stress syndrome and the sequelae of abuse, which are probably diagnosed too often in guideline correct psychotherapy, throw up questions on the appropriate therapy and possible injurious side effects. The social background to the psychotherapeutic fascination with trauma will be discussed.     

Langzeitergebnisse einer Funktionellen-Magnetresonanztomographie-Studie

In a controlled functional magnetic resonance imaging (fMRI) study the effect of psychodynamic short-term psychotherapy on cerebral activation of panic disorder patients was determined. In a linguistic go-no go paradigm behavioral measures and cerebral activation to affective word stimuli with threatening, neutral and positive content were assessed pretreatment and post-treatment in 9 patients with panic disorder. 18 healthy controls were scanned twice at the same intervals. In an additional long-term follow-up after approximately 3 years post-treatment the effect of brain activation changes during treatment on the long-term outcome of core symptoms (panic-related cognition and fear of body sensations) were determined. In accordance with the hypotheses increased limbic (hippocampus and amygdala) activation accompanied by low prefrontal activation to negative words were found. At treatment termination, panic-related symptoms had improved significantly and fronto-limbic activation patterns were normalized. Reduction of activation of the limbic system during treatment was predictive of a favorable long-term outcome. The results indicate that short-term psychodynamic treatment leads to changes in fronto-limbic networks, similar to previous findings on cognitive-behavioural treatment.     

Honeybee methodology, cognition, and theory: recording local directional decisions in interpatch foraging and interpreting their theoretical relevance

Investigations made into the cognitive decision making of honeybees (Apis mellifera) traveling from one flower patch to another flower patch (interpatch foraging) are few. To facilitate such research, we present methods to artificially emulate interpatch foraging and quantify the immediate decision making of honeybees (within 50 cm) choosing to fly an interpatch path. These “Interpatch Methods” are validated, applied, and shown to produce novel information for the field of honeybee spatial cognition. Generally, we demonstrate that a single foraging cohort of honeybees is shown to be capable of making decisions based upon different sets of learned cues, in the exact same context. Specifically, both terminal beacon orientation cues and compass navigation cues can guide the cognitive decision making of interpatch foraging honeybees; our bees chose both cues equally. Finally, the theoretical importance of decision making for interpatch paths is compared with the other foraging paths (outward and homing) with respect to the information available to recruited foragers and scout foragers. We conclude that the ability to analyze interpatch foraging is critical for a more complete understanding of honeybee foraging cognition and that our methods are capable of providing that understanding.     

Initial psychological effects of sexual abuse on female children as reflected in the Hand Test

Previous research regarding the initial effects of sexual abuse on children has varied in terms of methodologies, measurement instruments, and reported findings. Recent studies, however, suggest that projective techniques may be useful in resolving some of these inconsistencies. This study utilized the Hand Test to investigate the initial effects of sexual abuse on female children. Authenticated cases of sexually abused children were compared to a matched sample of presumably nonabused children. Significant differences on six variables were obtained between the groups but, more important, Hand Test patterns emerged which appeared to distinguish among those victims who: (a) were severely traumatized by the abuse, (b) displayed neurotic tendencies, and (c) did not seem to have suffered measurable detrimental effects. It was suggested that these findings may help reconcile conflicting views that have appeared in the literature.     

Psychosocial risk and resistance factors among children with chronic illness,healthy siblings,and healthy controls

Psychosocial risk and resistance factors within the domains of parental functioning, family Stressors, and family resources were examined as predictors of psychological adjustment and physical problems in juvenile rheumatic disease patients (N=93), their healthy siblings (N=72), and demographically matched healthy controls (N=93). Family socioeconomic status and background variables showed few consistent relationships with child functioning. However, a constellation of risk and resistance factors tended to show comparable associations with functioning for patients, siblings, and controls. Higher parental depression and medical symptoms and more family Stressors, sibling problems, and burden of illness on the family predicted more problems among the patients. These relationships held when disease duration and severity were controlled. For the siblings, increased parental and patient dysfunction, more family Stressors, and less family cohesion and expressiveness were associated with more problems. Although the associations were not as strong, mothers' depression and lack of family cohesion and expressiveness also were related to more adjustment problems among the control children. These findings imply that there may be a general association between certain risk and resistance factors and childhood adaptation.This research was supported in part by NIH Multipurpose Arthritis Center Grant AM20610, NIMH Grant MH16744, and Veterans Administration Medical and Health Services Research and Development Service Research funds. Jan Gottlieb provided valuable help in all phases of the research.

Attraktivitätsänderung der Aufgabe nach Mißerfolg. Kognitive Dissonanztheorie versus Leistungsmotivationstheorie

Zusammenfassung Nach der kognitiven Dissonanztheorie steigt die Attraktivität einer Aufgabe nach Mißerfolg, wenn die Vp die Aufgabe zuvor selbst gewählt und nicht zugewiesen bekommen hatte. Nach der Leistungsmotivationstheorie ist die Attraktivitätsänderung abhängig von einer durch den Mißerfolg verursachten Verringerung der erlebten Erfolgswahrscheinlichkeit in Wechselwirkung mit der Ausprägung des überdauernden Leistungsmotivs der Vp. Ändert sich die Erfolgswahrscheinlichkeit in Richtung auf eine Höhe von 30–40%, so steigt die Attraktivität der Aufgabe für erfolgszuversichtlich motivierte Vpn und fällt ab für mißerfolgsängstlich motivierte Vpn.In einem 2×2-Versuchsplan wurde Wahl oder Zuweisung der Aufgabe mit vorwiegendem Erfolgsmotiv der Vp kombiniert. Aus einer selbsthergestellten Attraktivitätsrangfolge von 9 verschiedenen Aufgaben wählt die Vp zwischen der 5. und 6. Aufgabe eine zur Bearbeitung aus oder erhält eine der beiden fest zugewiesen. Nach Mißerfolg stellt die Vp eine erneute Attraktivitätsrangfolge der Aufgaben her.Die innerhalb und zwischen den vier Bedingungskombinationen erhaltenen Ergebnisse entsprechen zu einem größeren Teil der Leistungsmotivationstheorie als der Dissonanztheorie. In der Bedingungskombination, für die beide Theorien gegensätzliche Voraussagen machen (Wahl-Mißerfolgsmotivierte), fallen die Befunde zugunsten der Leistungsmotivationstheorie aus. Diese Theorie zeigt jedoch Schwächen in der Voraussage von Attraktivitätsänderungen unter Zuweisungsbedingungen. Die Dissonanztheorie versagt bei den Mißerfolgsmotivierten. Verbesserungen der Theoriebildung und der experimentellen Prüfung werden erörtert.

Change in attractiveness of task after failure. Cognitive dissonance theory versus achievement motivation theory

Summary According to cognitive dissonance theory, the attractiveness of a task increases after failure only when the S has chosen the task but not when it is assigned to him. Achievement motivation theory, on the other hand, states that change in attractiveness depends on a reduction in perceived probability of success, caused by failure. In addition, probabilitiy of success also interacts with the dispositional characteristics of the S's achievement motive. If probability of success increases toward a value of 30–40 per cent, then the attractiveness of the task increases for hope of success Ss but decreases for fear of failure Ss.Choice or assignment of task was combined with predominantely hope of success or fear of failure Ss in a 2×2 experimental design. The S first ranked nine different tasks in their order of attractiveness. While some Ss could further choose to work on either the fifth or sixth ranking task, other Ss were assigned either one of these tasks. A second ranking of attractiveness was obtained after a failure experience.The results, both within and between the four experimental conditions, support mainly the predictions of achievement motivation theory rather than cognitive dissonance theory. In the condition in which opposing predictions can be derived from the two theories (i.e., when choice is offered to fear of failure Ss), the results clearly favor achievement motivation theory. However, this theory is less adequate in predicting changes in task attractiveness under task assignment conditions. Dissonance theory appears to be unable to predict the behavior of the fear of failure Ss. Implications for changes in the theories and further empirial tests are discussed.

     

Comparisons of children of depressed and nondepressed parents: A social-environmental perspective

Several lines of evidence indicate that a parent's depression may be a significant health and adaptational risk factor for his or her children. In a controlled comparison, children of 133 depressed parents had significantly more symptoms of emotional, somatic, and behavioral impairment than did children of 135 nondepressed parents. Additional results suggest that the more negative milieu found among families of depressed parents was a mediator of the effects of parental depression. A social-environmental perspective helped to identify aspects of parents' functioning, family stressors, and resources that were related to children's health. Variations in these stressors and resources were strongly related to the probability of disturbance among children of depressed parents.We gratefully acknowledge the assistance of Sarah Buxton, Marlene Koltin, Ruth Lederman, Roger Mitchell, and Deborah Shields in data collection and of Dani Lawler in data collection and analysis.

The use of self-efficacy scaling in training student clinicians: Implications for working with stutterers

A scaling technique developed by Bandura for determining an individual's personal performance expectations (self efficacy) was applied to student clinicians working with stutterers. The self-efficacy scores of clinicians conducting treatment increased significantly while the scores of clinicians without treatment experience showed no significant change. As the student clinicians gained clinical experience there appeared to be a corresponding reduction in fear and avoidance of the treatment situation. Clinician fear concerning stuttering treatment appeared to have little relation to performance in treatment as rated by supervisors. The results indicate that self-efficacy scaling may be used to indicate clinician avoidance of working with stuttering clients.
