A stochastic model for inter-keypress times in a typing task   总被引:2,自引:0,他引:2  
A mathematical model for the inter-keypress times (IKT) in a typing task is proposed. The model, which includes a diffusion process terminated by a single response threshold, was evaluated using data obtained from typists. The differences in performance for successive cross-hand and within-hand keypresses were examined using IKT distributions and hazard functions, and it was shown that the empirical hazard functions could be fit by the theoretical hazard function derived from the convolution of normal and inverse Gaussian random variables. Some possible applications of the model for the evaluation of fatigue and strategic effects in typing are suggested.  相似文献

Current interest in moral theorizing has been dominated by Kohlberg's cognitive-developmental view. Haan (1982) has challenged psychology's reliance on this rationalistic focus and has argued for a rethinking of morality's meaning in accord with everyday human experience. In light of this challenge, the present study gives both theoretical and empirical support to the advancement of a morality for everyday life. Specifically, a new measure called the Visions of Morality Scale (VMS) is reported. The VMS is sensitive to three dimensions which are necessary for an everyday morality: (1) a human constitutive component which is universally experienced by all human beings (empathy); (2) the inclusion of a behavioral component which reflects actual behavior (pro-social inclinations); and (3) a view of morality that is multilevel (private, interpersonal, and social). A brief sketch of the VMS is provided. Results are presented from a study of 181 high school students which relate the VMS to empathy and political orientation. Highly significant relationships were found among morality, political orientation, and empathy. In addition, results revealed numerous sex differences. Finally, the implications of an everyday morality are discussed.  相似文献

The teenage suicide rate in Zimbabwe did not change much during the 1970s, though the rate rose for female teenagers. Female teenagers used poison as a method of suicide more often than did adults, and self-immolation had increased in frequency among young women by the mid-1980s.  相似文献

The purpose of this study was to determine the effect of social support on parent-child interaction in a group of 19 adolescent mothers. The subjects participated in a 20-week model demonstration program in which they worked in a preschool classroom with skilled caregivers who modeled facilitative styles of interacting with young children. Each subject was videotaped while interacting with a 1- to 2-year-old child upon entering the program, midway through the program, and at the end. Results showed that girls who were 16 years or older significantly increased their frequency of using responsive, engaging, and elaborative styles of behavior. Those under age 16 did not show significant changes in these three behaviors. Overall, subjects significantly increased the duration of time they spent observing the child's play behavior.  相似文献

Anxiety sensitivity and panic attacks in a nonclinical population   总被引:1,自引:0,他引:1  
In the present study, we administered the Anxiety Sensitivity Index (ASI) and a modified version of the Panic Attack Questionnaire (PAQ) to 425 college students to determine whether high anxiety sensitivity ('fear of fear') occurs in the absence of a history of unpredictable ('spontaneous') panic attacks, or whether such attacks are a necessary precursor to high anxiety sensitivity. Based on their ASI scores, subjects were assigned to either the high, medium, or low anxiety sensitivity groups. High anxiety sensitivity subjects more frequently reported both a personal and family history of panic than did subjects in the other groups. Nevertheless, two-thirds of the high anxiety sensitivity subjects had never experienced an unpredictable panic attack. This suggests that the fear of anxiety can be acquired in ways other than through personal experience with panic.  相似文献

A large volume of evidence has supported the important role of psychological principles and variables related to the perception of, and response to, nociceptive stimulation. On the basis of this research, a number of psychological interventions have been developed and used successfully with pain patients. Despite the evidence, there has been a tendency for practitioners to neglect the contributing role of cognitive, affective, and behavioral factors in reports of pain by cancer patients. Cancer seems to hold a unique status in medicine and society at large. In this paper, the cancer pain literature is briefly reviewed and evidence is presented for various psychological determinants of the pain report and response that may be extended to pain associated with cancer. The implications of these data for understanding and treatment of cancer patients are described.  相似文献

The relationship of appraisal and coping to chronic illness adjustment   总被引:7,自引:0,他引:7  
There is evidence that adaptation to chronic illness may be affected by psychological factors, especially how patients appraise and cope with the stress of their illness. The purpose of the present study was to examine the relationship of stress appraisal and coping responses to multiple behavioral indices of illness adjustment among patients with diverse chronic medical conditions. One hundred and one patients admitted to a multidisciplinary medicine/psychiatry unit completed measures of functional impairment, depression, symptom severity, and the Ways of Coping Checklist--Revised. Hierarchical regression analyses indicated that emotion-focused coping was positively related to poor psychosocial adjustment and depression after controlling for physician rated disease severity. Appraising chronic illness as holding one back predicted greater emotion-focused coping responses and poorer adjustment to illness. The use of problem-focused coping strategies was generally unrelated to illness adjustment. These findings suggest the presence of an emotion-focused coping triad consisting of wishful thinking, self blame, and avoidance, all of which appear to be maladaptive strategies when coping with chronic medical conditions. Implications for coping skills training and the need for longitudinal research is discussed.  相似文献

Pessimistic explanatory style and response to illness   总被引:2,自引:0,他引:2  
Previous studies have shown that a pessimistic explanatory style is a risk factor for illness, but the factors linking explanatory style and illness are unknown. One's characteristic response to poor health may mediate this relationship. Perhaps pessimistic individuals act helplessly in the face of their symptoms, thereby exacerbating disease. In the present study, we investigated this possibility by asking 96 young adults to complete measures of explanatory style, habitual response to illness, and ways of coping during their most recent episode of illness. Subjects who explain bad events pessimistically (with internal, stable, and global causes) reported more frequent illnesses during the past year and rated their overall health more poorly than those who habitually favor external, unstable, and specific explanations. When ill, the pessimistic subjects were less likely than their optimistic counterparts to take active steps to combat their illness. Our results suggest that one pathway leading from pessimistic explanatory style to poor health is mundane: passivity in the face of disease.  相似文献

The purpose of this investigation was to examine further the contention of Alain et al. (1988) that a third priming type exists, called nonselective restricted (NSR) and controlled by response probability, which is distinct from those types influenced by foreperiod duration (nonselective general priming) and prediction probability (selective priming). In a four-choice reaction time (RT) task, prediction probability (.5, .7, & .9, indicating the likelihood of a particular response) and response probability (.5, .9, denoting the likelihood that a response would be needed at all) exerted significant but noninteractive effects on RTs for prepared responses (most probable), suggesting that each of these probabilities influence different priming types (Sternberg, 1969; selective and NSR, respectively). This was further indicated by the fact that prediction probability, but not response probability, significantly altered RTs for the unprepared (lesser probable) responses. Finally, the hypothesized nonselective character of NSR priming (i.e., all outputs controlled by response probability are equally affected by its value changes) was supported when responses were equiprobable, and, while the null effect of response probability just mentioned seemingly argued against this property when selective priming took place, the interpretation provided herein negated this opposition.  相似文献

Previous work by Porac, Coren, and Searleman (1986) looked at overt attempts to change hand preference from the left to the right side. We extended this research by studying individuals who shifted their handedness from the left to the right side as well as a group who attempted a shift in the opposite direction (right to left). Comparisons of the two shift attempts revealed that the timing, method, and agent of change differed significantly for right versus left shifts. More right than left shifts were successful. Overall, most shift attempts were rated as unsuccessful because they did not result in a handedness classification consistent with the direction of the shift. Individuals classified as successful shifters, whether in the right or left direction, displayed a more ambihanded behavioural pattern than either unsuccessful shifters or the no shift control group. Evidence suggested that left-shift attempts were promoted by original ambihanded tendencies but that ambihandedness in successful right shifts stemmed from the partial success of the switch attempt.  相似文献
