Biological and psychosocial risk factors in high-risk pregnancy and their relation to infant developmental outcomes were explored in a sample of 153 pregnant Israeli women who had pregestational diabetes mellitus, gestational diabetes mellitus, or were nondiabetic. Questionnaires on coping and resources as well as well-being and distress during the 2nd trimester were administered. Estimates of maternal fuels (HbAlc and fructosamine) were obtained throughout pregnancy. At 1 year, offspring were administered the Bayley Scales of Infant Development and mother-infant interactions were observed. Infants of mothers in the diabetic groups scored lower on the Bayley Scales and revealed fewer positive and more negative behaviors than did infants of mothers in the nondiabetic group. Infant outcomes in the maternal diabetic groups were associated with maternal metabolism. Maternal coping and resources differed in the 3 groups and differentially predicted infant development.  相似文献

People remember information better if they generate the information while studying rather than read the information. However, prior research has not investigated whether this generation effect extends to related but unstudied items and has not been conducted in classroom settings. We compared third graders’ success on studied and unstudied multiplication problems after they spent a class period generating answers to problems or reading the answers from a calculator. The effect of condition interacted with prior knowledge. Students with low prior knowledge had higher accuracy in the generate condition, but as prior knowledge increased, the advantage of generating answers decreased. The benefits of generating answers may extend to unstudied items and to classroom settings, but only for learners with low prior knowledge.  相似文献

In response to a competitive environment, hospital administrators are pressuring physicians to discharge Medicare patients “sicker and quicker” and to transfer indigent patients from their emergency rooms. This paper compares health administrators' ethics to public expectations regarding financially motivated hospital transfers and discharges. Health administrators use balancing strategies: code morality, survivalism, mission dependency, and tithing. Public expectations, exemplified in P.L. 99–272, P.L. 99–509, and recent case law, are based on norms of potential for patient harm and patient occupancy. These norms are morally preferable to those of health administrators; they reinforce the value of identified lives and the reliability of the health care system.  相似文献

The effects of 2 forms of response interruption and redirection (RIRD)-motor RIRD and vocal RIRD-were examined with 4 boys with autism to evaluate further the effects of this intervention and its potential underlying mechanisms. In Experiment 1, the effects of motor RIRD and vocal RIRD on vocal stereotypy and appropriate vocalizations were compared for 2 participants. In Experiment 2, the effects of both RIRD procedures on both vocal and motor stereotypy and appropriate vocalizations were compared with 2 additional participants. Results suggested that RIRD was effective regardless of the procedural variation or topography of stereotypy and that vocal RIRD functioned as a punisher. This mechanism was further explored with 1 participant by manipulating the schedule of RIRD in Experiment 3. Results were consistent with the punishment interpretation.  相似文献

Signals during delays to reinforcement may lessen reductions in responding that typically occur when there is a delay between a response and its reinforcer. Sparse applied research has been devoted to understanding the conditions under which responding may be maintained when delays to reinforcement are introduced. We evaluated the extent to which providing signals during delay fading affected responding in the context of differential reinforcement of communication responses. Three individuals were exposed to gradually increasing signaled and unsignaled reinforcement delays in multiple‐schedule and/or withdrawal designs. Results for 2 of 3 participants suggested that (a) the presence of signals facilitated response maintenance under delayed reinforcement and (b) coordinated basic and applied research may advance both conceptual understanding and clinical outcomes of delayed reinforcement.  相似文献

Given the extreme focus on perceived physical defects in body dysmorphic disorder (BDD), we expected that perceptual and cognitive biases related to physical appearance would be associated with BDD symptomology. To examine these hypotheses, participants (N=70) high and low in BDD symptoms completed tasks assessing visual perception and cognition. As expected, there were significant group differences in self-relevant, but not other-relevant, cognitive biases. Perceptual bias results were mixed, with some evidence indicating that individuals high (versus low) in BDD symptoms literally see themselves in a less positive light. Further, individuals high in BDD symptoms failed to demonstrate a normative self-enhancement bias. Overall, this research points to the importance of assessing both cognitive and perceptual biases associated with BDD symptoms, and suggests that visual perception may be influenced by non-visual factors.  相似文献

Cognitive models of obsessive-compulsive disorder (OCD) suggest that misinterpreting intrusive thoughts exacerbates obsessional thinking. To evaluate this hypothesis, healthy participants (N=91) were prompted to recollect their unwanted thoughts, and then beliefs about the immorality of these thoughts were manipulated. Next, participants completed implicit and explicit measures of self-evaluation and appraisals of unwanted thoughts. Results from structural regression analyses indicated that explicit responses to unwanted thoughts, such as evaluations of the significance of intrusive thoughts and state self-esteem, were predicted by pre-existing obsessional beliefs, but not by the morality instruction manipulation. In contrast, implicit responses, such as appraisals of unwanted thoughts as relatively important and evaluations of the self as relatively immoral and dangerous, were predicted by the interaction between specific obsessional beliefs (e.g., intolerance of uncertainty) and the morality instructions. Findings largely support cognitive models of OCD and suggest unique predictors of implicit and explicit responses to unwanted thoughts.  相似文献

We present a framework based on psycholinguistic theory to explain how individuals spell auditorily-presented information. We use the framework to predict and test how spelling-related characteristics of brand names and factors related to the context in which brand names are presented (e.g., spelling primes) will make the brands more or less memorable. Further, we reveal the process through which spelling-related linguistic variables influence brand recall: the dual-code (both written and auditory) that results from spelling a brand correctly leads to greater ability to later recall the brand. Our framework identifies two routes that interact when individuals have to transcribe a brand: the lexical (top-down) route and the sublexical (bottom-up) route.  相似文献
