Flashbulb and factual memories: the case of Rabin's assassination

Similarities and differences between factual memories (FTM) and flashbulb memories (FBM) of the assassination of Israel's Prime Minister, Itzhak Rabin, were explored. About two weeks after the assassination 61 Israeli students filled out a questionnaire which focused on the event and the circumstances in which they had first learned about it. About 11 months later they filled out again the same questionnaire, and self‐assessed their emotional and cognitive reactions to the assassination, as well as specific properties of their memory; such as confidence in its accuracy, and the amounts of rehearsals and visual representations. Comparative analysis of the participants' responses on the two questionnaires uncovered decrements of about 25% in FTM accuracy, and about 36% in FBM consistency. Rehearsals and visual representations were more common in FTM than in FBM, but the levels of confidence in memory accuracy were similar for both. FTM which were presumably based on information provided by television broadcasts, appeared to have episodic properties. The data seem to support the hypothesis that FTM and FBM of traumatic public events are encoded together; perhaps by the same memory mechanism. Copyright © 2003 John Wiley & Sons, Ltd.     

Dissociation,Physical Pain,and Suicide: A Hypothesis

The hypothesis of this paper states that at least some suicidal individuals are characterized by a disposition toward dissociation manifested in relative insensitivity to physical pain and indifference to their bodies. Three main topics are discussed: dissociation and suicide, psychological aspects of pain, and pain and suicide. Various theoretical and experimental studies suggest that certain stress conditions lead to the development of dissociative tendencies, and that once these tendencies are established, they become an integral part of suicidal behavior. Psychological variables that affect pain tolerance are presented and they include perception, motivation, emotions, and behavioral and cognitive strategies of pain control. These can increase tolerance of pain in suicidal individuals, making the suicidal act possible. The specific relationships of pain and suicide are then introduced through an examination of pain analgesia in the phenomenon of self-harm. The integration of the material suggests that early and continuous stress lead to the simultaneous development of dissociative tendencies (including indifference to the body and pain) and heightened vulnerability to stress. These dispositions may facilitate suicidal behavior in the face of mounting intolerable stress, helplessness, and hopelessness. Preliminary empirical support for the present hypothesis is cited. This hypothesis shifts the focus of attention from the question of what causes suicide to what facilitates suicide, and in so doing suggests new directions for research and therapy.     

MODIFICATION OF HUMAN GASTRIC ACID SECRETION WITH OPERANT-CONDITIONING PROCEDURES1

In an attempt to control gastric acid secretion with operant-conditioning techniques, four normal women were given visual feedback on gastric pH plus money reinforcers. When money was made dependent on increased secretion in a differential-reinforcement-of-high-rates schedule, the rate of secretion of three of the four subjects increased to three times baseline. When money was then made dependent on decreased secretion in a differential-reinforcement-of-other-behaviors schedule, the rate of secretion of these three subjects returned to baseline levels. Heart rate, respiratory frequency, abdominal electromyographic activity, and stomach motility (measured by the electrogastrogram method) were not consistently correlated with acid secretion across subjects, although individual subjects showed substantial correlations between acid secretion and one or more other physiological response.     

The relative lability of mobile and stationary components in a visual-motor adaptation task

The results of previous studies of intermanual transfer of prism adaptation may have been biased because the arm was mobile during training, rather than for instance the head. It was hypothesized that adaptation will be more associated with a joint when it is mobile rather than stationary. Intermanual transfer when arm was mobile and head stationary was compared with that when head was mobile and arm stationary. Also measured was the adaptation persisting when the mobile part in training was stationary in testing. The results showed, against the original hypothesis, that adaptation tends to be associated with a stationary joint. This fits in with evidence that there is greater position uncertainty in a stationary joint and that this is associated with adaptability.     

Effect of Concurrent Visual Feedback Frequency on Postural Control Learning in Adolescents

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.     

Difficult Differences: A Socio‐cultural Analysis of How Diversity Can Enable and Inhibit Creativity

The relationship between diversity and creativity can be seen as paradoxical. A diversity of perspectives should be advantageous for collaborative creativity, yet its benefits are often offset by adverse social processes. One suggestion for overcoming these negative effects is perspective taking. We compared four dyads with low scores on trait perspective taking with four dyads who were high on trait perspective taking on a brainstorming task followed by reconstructive interviews. Trait‐based perspective taking was strongly associated with greater creativity. However, contrary with expectation, interactional perspective taking behaviors (including questioning, signaling understanding, repairing) were associated with lesser creativity. The dyads that generated the fewest ideas were most likely to get stuck within ideational domains, struggling to understand one‐another, having to elaborate and justify their ideas more. In contrast, the dyads that generated many ideas were more likely to recognize each other's ideas as valuable without extensive justification or negotiation. We suggest that perspective taking is crucially important for mediating diversity in the generation of new ideas not only because it enables understanding the perspective of the other, but because it entails an atmosphere of tolerance, playfulness, and mutual recognition.     

Manic temporality

Time-consciousness has long been a focus of research in phenomenology and phenomenological psychology. We advance and extend this tradition of research by focusing on the character of temporal experience under conditions of mania. Symptom scales and diagnostic criteria for mania are peppered with temporally inflected language: increased rate of speech, racing thoughts, flight-of-ideas, hyperactivity. But what is the underlying structure of temporal experience in manic episodes? We tackle this question using a strategically hybrid approach. We recover and reconstruct three hypotheses regarding manic temporality that were advanced and modeled by two pioneers of clinical phenomenology: Eugène Minkowski (1885–1972) and Ludwig Binswanger (1881–1966). We then test, critique, and refine these hypotheses using heterophenomenological methods in an interview-based study of persons with a history of bipolar and a current diagnosis of acute mania. Our conclusions support a central hypothesis due to Minkowski and Binswanger, namely, that disturbance in the formal structure of temporal experience is a core feature of mania. We argue that a suitably refined variant of Binswanger’s model of disturbance in manic protention helps to explain a striking pattern of impaired insight and impaired reasoning in manic episodes.     

Impact of Social Determinants on Parent Sense of Competence in Mothers Who are Homeless or Poor Housed

Unfavorable social determinants can impact mothering of young children who are homeless or poor housed and parent sense of competence. Social determinants influence on mothers’ parent sense of competence parent self-efficacy and satisfaction was investigated. Homeless mothers reported worse scores than poor housed mothers on 5 of 10 social determinants including: mother moves, abuse, un/underemployment, less stable partner relationships and student roles. Homeless mothers scored lower than poor housed mothers on parent sense of competence satisfaction and parent sense of competence total, but not on parent sense of competence efficacy. No one social determinant predicted parent sense of competence. Results underscore the need to address social determinants of health in occupational therapy community-based practice.     

On the Emergence of the Subject

The paper retraces the elaboration of a model that accounts for the emergence of subjectivity-the possibility to distance self from others and oneself-if we consider people as always taken in social and cultural streams of meaning and tensions. It builds a model considering first, human experience as possible when a person takes distance from the here-and-now. Second, it suggests considering two general semiotic streams that feed in, or support, that distancing-social and cultural discourses, and personal experience. Third, a knitting model suggests the constant creation of personal patters out of these two streams. Fourth, a dynamic, star-like model is proposed to account for the actual and constant emergence of subjectivity out of such social and cultural configurations. The model is constituted by a 2, 3 or N-number of eight-shaped crossing loops, resulting in a star-like model situated in a 3 dimensional space. The proposition is to analyze a person in a specific situation: the attractors enabling these loops, or end-points of the star, are the relevant social and cultural elements: others with whom he or she interacts, specific bodies of shared knowledge, social representations, cultural elements and tools, and so on. In each situation, the relative strength of these elements, or the tension they generate, are negotiated by the person; the unique ways of dealing with that situation and inviting solutions can thus be seen as the emergent subjectivity. The model is explored to account for developmental dynamics at various scales in the lifecourse. Finally, the pragmatic interest of a model emphasizing complex configurations, not simple causalities, is recalled.
