A new model, called acceleration model, is proposed in the framework of the heterogenous case of the graded response model, based on processing functions defined for a finite or enumerable number of steps. The model is expected to be useful in cognitive assessment, as well as in more traditional areas of application of latent trait models. Criteria for evaluating models are proposed, and soundness and robustness of the acceleration model are discussed. Graded response models based on individual choice behavior are also discussed, and criticisms on model selection in terms of fitnesses of models to the data are also given.This research was supported by the Office of Naval Research (N00014-90-J-1456). 相似文献

Observations of eye movements of young children in a modified preferential looking task suggest a change in the visual looking pattern taking place during a very brief time between 32 and 33 months of age. In the younger children, a grating stimulus elicited eye movements towards the target followed by a few seconds of focused attention; in the older children a visual avoidance behavior was observed where subjects looked consistently in the opposite direction of the target. An analysis of video recordings suggests that this avoidance pattern was a composite of a very brief initial target-directed eyemovement which was quickly arrested, and followed by eye movements in the opposite direction, initiating a search of the visual scene. 相似文献

An adaptation of the Stroop color-naming task was used to investigate selective information processing related to eating behavior in 90 undergraduate women. This study differed from previous studies by (a) treating eating behavior as a continuous variable and (b) looking at five separate categories of words including color, neutral, food, body shape, and other emotionally salient words. We did not find a strong pattern of relation between the Stroop task and eating and body image measures. Results suggest that in a nonclinical population, direct methods of accessing cognitions related to eating may be more fruitful than indirect measures. 相似文献

A sample of 250 people completed a questionnaire where they rated 30 statements describing their behavior and experiences during a recent time pressure situation. A factor analysis resulted in three factors: Personal Burden, Work Problems and Difficulties, and Challenge Orientation. People high on this last factor liked the excitement of being under pressure, were very absorbed in the task, and showed signs of being effective in dealing with the situation. Such individuals were having what has been identified as a flow experience often observed in sports and the arts. The results of this study suggest that effective coping with time pressure is related to taking a task-oriented attitude, avoiding self-preoccupation, and using time management skills to focus on successful achievement. 相似文献

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training. 相似文献

Interest has been steadily building in the impact of stress on psychological and physiological functioning, in particular on immune system responses, furthering the concept of a strong connection between the mind and the body. Implications for prevention of disease onset or treatment of stress-induced illness or immunocompromised conditions have been explored through the implementation of stress management techniques. Cognitive behavioral stress management interventions, biofeedback, relaxation, guided imagery, hypnosis, individual and group psychotherapy, aerobic exercise, and guided self-efficacy treatment are briefly reviewed to identify possible treatment mechanisms that may affect immune function and promote quality of life. The application of behavioral techniques to reduce distress and sharpen coping skills has great promise in reducing the costs associated with chronic disease and in enhancing quality of life among those afflicted.Presented at the APA Presidential Miniconvention, To Your Health: Psychology Through the Life Span, Session VIII, Assuring a Healthy Lifestyle: Psychology Delivers.

Reading is assumed to play an important role in the development of literate persons in that it is consciousness-altering activity. The manner by which reading contributes to development is unclear, however, and has been debated by social scientists for some years. Despite the importance of reading in adult life, only recently have researchers devoted significant attention to what and how well adults read. Less scrutiny has been directed toward understanding what sorts of benefits may be gained from reading in adult life and how reading contributes to adult development. This paper describes adults' reading practices across a variety of social contexts, the types of skills employed in these practices, and how reading may contribute to adult cognitive development. Implications deriving from a better understanding of adult reading practices and skills across the life span are discussed. 相似文献

Previous research indicates that blood pressure may impact a variety of cognitive functions, including short-term memory, abstract reasoning, visual-spatial abilities, and attention (Boller, Vrtunski, Mack, & Kim, 1977; Elias, Robbins, Schultz, & Pierce, 1990; Franceschi, Tancredi, Smirne, Mercinelli, & Canal, 1982; Mazzucchiet al., 1986). However, studies which have assessed the cognitive functioning of hypertensive adults have offered conflicting results, particularly when hypertension levels were in the mild range (e.g., Bolleret al., 1977; Eliaset al., 1990; Elias, Wolf, D'Agostino, Cobb, & White, 1993; Farmeret al., 1987, 1990; Franceschiet al., 1982; Pérez-Stable, Coates, Halliday, Gardiner, & Hauck, 1992; Schmidtet al., 1991; Waldstein, Ryan, Manuck, Parkinson, & Bromet, 1991). A number of factors may contribute to the inconsistent findings in this area. Researchers have employed a wide range of neuropsychological instruments to assess varying domains of cognitive function. Sample sizes in some studies have been too small to ensure sufficient power. Finally, studies have employed varying methodological control over potential confounding factors such as concurrent medical conditions, alcohol abuse, psychiatric disorders, or antihypertensive medication. This study compared male veterans with blood pressures in the mildly hypertensive range (n=166) to normotensive veterans (n=176) on neuropsychological measures of verbal fluency, visual-spatial ability, verbal and visual memory, dexterity, attention, and executive functions. Results revealed that, after controlling for differences in education and income, there was no relationship between mild hypertension and combined measures of cognitive performance. The present findings suggest that mild hypertension alone has little effect on cognitive function in adults. 相似文献

Strong empirical evidence was obtained in support of the proposition that nonabsolute/relativistic (N/R) thinking is a unifying commonality underlying four postformal models of higher-order thinking, namely, problem finding, dialectical reasoning, relativistic operations, and reflective judgment. Within the construct of N/R thinking, two dimensions—the basic form and the epistemic view—and two levels—the formal form and the postformal form—were differentiated as hypothesized. The findings clarify logical relationships among the models as well as provide a common link unifying their diversity. Implications and suggestions for future research are provided. 相似文献

The focus of this study was to investigate the relationship between formal and postformal systematic metasystematic reasoning. Shayer's (1978) chemicals task and a modified version of Kuhn and Brannock's (1977) plant task were used to measure formal thinking and Commons, Richard, and Kuhn's (1982) multisystem task and balance-beam task to detect postformal reasoning. Subjects were university students from the humanities and social sciences (N=35). For each subject, a composite score was defined by taking into account the highest score in the tasks measuring the same developmental stage. Findings indicated that composite scores of formal and postformal reasoning were significantly correlated. Results also indicated that full formal operations are not a necessary condition for systematic thinking. The developmental status of systematic reasoning should be defined more strictly than has so far been the case. Further studies should focus on metasystematic reasoning as a possible postformal mode of reasoning. Longitudinal designs are also required to assess whether metasystematic reasoning develops in adulthood. 相似文献
