Effects of Computer-Based Fluency Training on Concept Formation

This study provides a preliminary analysis of how the techniques of fluency training can be combined with systematic concept instruction to improve the learning of complex verbal concepts. Fluency techniques, which require the learner to respond accurately at high rates, have typically focused on definition learning when teaching concepts. Instructional psychologists, however, recommend multiple exemplar training for conceptual instruction. To examine this issue, 41 undergraduate students completed a computer-based instructional module on logical fallacies. Participants were assigned to one of four groups, with the modules for each group differing only in the type of practice provided—either fluency or practice with either examples or definitions. Examination of posttest scores revealed significantly higher scores for participants in the examples groups than those in the definitions groups, but low experimental power prevented a clear conclusion to be drawn about differences between the fluency and practice groups. Implications of results and several methodological issues relevant to this area of research are discussed.     

Different athletes cope differently during a sport competition: a cluster analysis of coping

This study aimed at examining the ways in which different athletes may combine the use of several coping strategies and at testing whether perceived goal attainment, affective states, and experience of control would differ across distinctive profiles of coping. A sample of 151 French-Canadian athletes out of 200 who were approached by a research assistant completed l’Inventaire des Strat gies de Coping en Comp tition Sportive (Gaudreau & Blondin, 2002a), the PANAS ( Watson, Clark, & Tellegen, 1988), and a series of items measuring experience of control and perceived goal attainment. Results of a cluster analysis indicated that athletes could be classified in four groups according to their in-competition use of coping strategies. After controlling for athletes’ self-referenced goal attainment, their experience of control, positive affective state, and anger-dejection state differed significantly (p<0.008) across the four profiles of coping. Athletes who have used high level of task-oriented coping in combination with low level of disengagement-oriented coping reported better goal and psychological adjustment than athletes who have used high level of disengagement-oriented coping in combination with low level of task-oriented coping. Overall, these findings suggested that research should move from coping strategies to coping profiles in order to provide a deeper understanding of how different individuals cope with stress.     

Bioterrorism, Embryonic Stem Cells, and Frankenstein

The stem cell controversy raises a fundamental question for humankind. Does science have a right to pursue knowledge whatever the cost? Our Enlightenment culture says yes. However, human history and literature are sending warning signals. Ethical issues impact the “knowledge for its own sake” imperative, and must be addressed.     

Predictors of Family Functioning Within Alcoholic Families

This study assessed the effects of various predictor variables on dimensions of functioning within alcoholic families. Participants were 173 college student volunteers from alcoholic families who completed a measure of family functioning, demographic questions, and questions related to experiences in their families of origin. Child abuse, spousal violence, parental divorce, length of time living with an alcoholic parent, parental marital status, and parental availability and predictability significantly affected family functioning, whereas frequency of parental drinking did not. Results suggest that quality of parental interactions with children is more important for functioning in alcoholic families than frequency of parental drinking.     

Is flashbulb memory a special instance of source memory? Evidence from older adults.

Flashbulb memories (FMs) are vivid, stable memories for the reception of arousing, consequential news. Although such memories have been found in people of all ages, in the only examination of age differences to date, Cohen, Conway, and Maylor (1994) reported that older adults were less likely than young adults to experience a FM. We hypothesised that FM would be impaired in older adults with reduced frontal lobe (FL) function. To test this hypothesis, we asked older adults, who had been characterised according to FL function, to recall details of the moment that they first heard the news about the deaths of Princess Diana and Mother Teresa. Long-term retention was tested 6 months later. Details concerning the reception of the news about Princess Diana's death were retained better than those associated with Mother Teresa's death. Importantly, there was no evidence that memory for these contextual details was related to FL function. A measure of medial temporal lobe function, derived from neuropsychological tests of episodic memory, was also not associated with memory for the reception events, although it was associated with memory for the details of an everyday autobiographical event. We speculated that emotionally arousing autobiographical memories may be qualitatively different from everyday memories and may involve the amygdala.     

Neighborhood effects in spelling in adults

The participants were asked to spell aloud words for which there were either many orthographically similar words (a dense neighborhood) or few orthographically similar words (a sparse neighborhood). Words with a dense neighborhood were spelled faster and more accurately than were words with a sparse neighborhood. This finding is consistent with the hypothesis of Rapp, Epstein, and Tainturier (2002), that the cognitive spelling system has an interactive architecture incorporating feedback between individual graphemes and orthographic lexeme representations.     

Les unités de soins intensifs psychiatriques (USIP) : expériences françaises et internationales

Psychiatric Intensive Care Units (PICU) propose a secure setting for patients with acute behavior disturbances who can not be managed in psychiatric general wards. Physical violence acts against patients or hospital staff, substance abuse, non-compliance for care and treatment, intensity of symptoms or absconding are frequent motives for admission. Patients are compulsorily detained in secure conditions. They are admitted from psychiatric facilities of a health area or by agreement between hospitals. Multidisciplinary working in psychiatric intensive care is essential, delivered by qualified staff. Care and treatment must be centered on the patient, multidisciplinary, intensive, comprehensive with an immediacy of response to critical situations. As length of stay should not exceed 2 months in duration, interface and liaison with original services of patients are important issues. In France, PICU exist notably at Cadillac, Lyon, Paris, Nice, Eygurande, Montpellier, Pau and Prémontré. These facilities appear as a missing level, an interesting alternative in mental health care system, between psychiatric general wards and maximum security hospitals. This paper reports the creation of a National Association of PICU in France, the existence of national minimum standards and international experiences.     

Scientific Self-Regulation—So Good, How Can it Fail?

To be a functional alternative to government regulation, self-regulation of science must be credible to both scientists and the public, accountable, ethical, and effective. According to some, serious problems continue in research ethics in the United States despite a rich history of proposed self-regulatory standards and oversight devices. Successful efforts at self-regulation in stem cell research contrast with unsuccessful efforts in research ethics, particularly conflicts of interest. Part of the cause for a lack of success in self-regulation is fragmented, disconnected oversight, and failure to embody genuine scientific and public consensus. To be accountable, credible and effective, self-regulation must be inclusive and multidisciplinary, publicly engaged, sufficiently disinterested, operationally integrated with institutional goals, and must implement a genuine consensus among scientists and the public. The mechanisms of self-regulation must be sufficiently broad in their oversight, and interconnected with other institutional forces and actors, that they do not create fragmented solutions.

An analysis of immediate serial recall performance in a macaque

There has been considerable research into the ability of nonhuman primates to process sequential information, a topic that is of interest in part because of the extensive involvement of sequence processing in human language use. Surprisingly, no previous study has unambiguously tested the ability of nonhuman primates to encode and immediately reproduce a novel temporal sequence of perceptual events, the ability tapped in the immediate serial recall (ISR) task extensively studied in humans. We report here the performance of a rhesus macaque on a spatial ISR task, closely resembling tasks widely used in human memory research. Detailed analysis of the monkey’s recall performance indicates a number of important parallels with human ISR, consistent with the idea that a single mechanism for short-term serial order memory may be shared across species.
