Much of the methodology in stress research focuses on stress manifestation and organismic reactions to life’s crises. In contrast, the present study sought to identify the major sources of stress and the nature of those sources. The results revealed a consistent pattern in high and low stressors throughout the 3-year period of the study, and differences only of intensity between males and females, not type of stress. Except for individuals’ temporal variations in critical events, the highest stressors for the groups were external, primarily financial and time management. Internal sources, such as personal relationships and self-absorption, were typically the lowest concerns. Everyday problems arising from current life styles seem to be significant sources of stress.  相似文献

Genetic counselors have participated in the Michigan Newborn Screening Program on a contractual basis since 1988. Their role includes newborn screening education and training, newborn nursery site visits, and monitoring newborn screening in hospitals. Their impact has been to improve the quality of newborn screening services by reducing errors and increasing completion of data fields on newborn screening cards, improving hospital nursery cooperation and problem solving, and enhancing health department response to specific problems.  相似文献

In some cases a person's religious beliefs can cause or exaccerbate emotional problems. Sometimes religious concepts can be used to ameliorate a client's problems. In dealing with Christian clients, the RET therapist can utilize the teachings and actions of Jesus in leading a client to recognize irrational beliefs. This paper illustrates and discusses rational teachings and actions of Jesus as regards four basic irrational beliefs and eleven underlying irrational beliefs.Sandra D.M. Warnock, M.A., served as a missionary to Hawaii with the Home Mission Board of the Southern Baptist Convention and as Minister of Outreach at Vinton Baptist Church, Vinton, Virginia. She was Senior Staff Clinician at Hollins Communications Research Institute in Hollins College, Virginia and is currently an adjunct lecturer in Psychology at Southside Virginia Community College in Keysville, Virginia.  相似文献

In three experiments, musically trained and untrained adults listened to three repetitions of a 5-note melodic sequence followed by a final melody with either the same tune as those preceding it or differing in one position by one semitone. In Experiment 1, ability to recognize the final sequence was examined as a function of redundancy at the levels of musical structurein a sequence, contour complexity of transpositions in a trial, and trial context in a session. Within a sequence, tones were related as the major or augmented triad; within a trial, the four sequences began on successively higher notes (simple macrocontour) or on randomly selected notes (complex macrocontour); and within a session, trials were either blocked (all major or all augmented) or mixed (major and augmented randomly selected). Performance was superior for major melodies, for systematic transpositions within a trial (simple macrocontours), for blocked trials, and for musically trained listeners. In Experiment 2, we examined further the effect of macrocontour. Performance on simple macrocontours exceeded that on complex, and excluded the possibility that repetition of the 20-note sequences provided the entire benefit of systematic transposition in Experiment 1. The effect of musical structure (major/augmented) was also replicated. In Experiment 3, listeners provided structure ratings of ascending 20-note sequences fromExperiment 2. Ratings onsame trials were higher than those on correspondingdifferent trials, in contrast to performance scores for augmentedsame anddifferent trials in previous experiments. The concept of functional uncertainty was proposed to account for recognition difficulties on augmented same trials. The significant effects of redundancy on all the levels examined confirm the utility of the information-processing framework for thestudy of melodic sequence perception.  相似文献

Research has shown that many individuals do not routinely evaluate new information for consistency with respect to what they already know. One factor that may affect the likelihood of critical evaluation is whether or not the information is the central focus of the message. Two experiments tested this possibility by establishing differential emphasis of false information within complex sentences. Half of the target sentences contained a false fact in the main clause and half contained a false fact in the subordinate clause. In Experiment 1 subjects verified 64 sentences presented orally as either true or false. In Experiment 2 subjects read and evaluated 20 paragraphs for the presence of false information. As expected, subjects were less likely to report the false information when it was conveyed as logically subordinate rather than central. The results suggest one explanation for deficits in comprehension monitoring and have implications for understanding susceptibility to persuasive communications.  相似文献

One of the more important and emerging fields in which psychologists collaborate with other disciplines is psychoimmunology. Centuries of clinical anecdote and decades of psychosomatic hypotheses have gained credibility in the eyes of the medical establishment—and many patients—by the systematic investigation of mechanisms potentially explaining how events intrapsychic and interpersonal could affect physical disease processes. The central nervous system is connected with the immune system by both neuronal and endocrinological pathways. The immune system has been found to mediate the organism’s response to aberrations of its own normal functions, as well as to invading organisms from without. AIDS, arthritis, asthma, lupus, and herpes are some of the illnesses in which research is demonstrating important relationships among psychosocial and immunological factors and disease course. In this article, we first discuss the immunological apparatus in order to provide a base for subsequent discussions of the effects of stress on immune function. Then we discuss malignant diseases and current evidence that disease course is related to both psychosocial stressors and immune function. We next discuss a model of these interactions, and finally we talk about interventions incorporating psychosocial factors aimed at influencing immune status and, thus, disease course.  相似文献
