American psychologists are informed on Pavlov’s work on conditional reflexes but not on the full development of his theory of higher nervous activity. This article shows that Pavlov’s theory of higher nervous activity dealt with concepts that concerned contemporary psychologists. Pavlov used the conditioning of the salivary reflex for methodological purposes. Pavlov’s theory of higher nervous activity encompassed overt behavior, neural processes, and the conscious experience. The strong Darwinian element of Pavlov’s theory, with its stress on the higher organisms’ adaptation, is described. With regard to learning, Pavlov, at the end of his scholarly career, proposed that although all learning involves the formation of associations, the organism’s adaptation to the environment is established through conditioning, but the accumulation of knowledge is established by trial and error.  相似文献

A questionnaire monitoring occupational aspiration, ethnic identification, adolescent experience, and self-esteem was administered to a large sample of Indian and Anglo-Saxon British male and female adolescents attending school in the West Midlands. The relationship between these variables and differences between the four groups were consistent with predictions derived from the social identity approach to intergroup relations and group behaviour (Tajfel & Turner, 1979). Indian males were found to possess a social mobility belief structure that mediates high occupational aspirations and keeness to marry out of their ethnic group. In contrast, Indian females were found to possess a social change belief structure associated with acceptance of the status quo and lower aspirations. Males and Anglo-Saxons reported higher self-esteem than females or Indians. The adolescent experience findings were less clear, but were consistent with the general interpretation of the data that the differences in intersex relations and gender-related experiences are contingent on ethnicity.  相似文献

A technique is described in which line-drawn pictures can be rapidly interlaced, allowing for sequential part presentation or tachistoscopic presentation on the Apple II. This is accomplished using a two-stage process in which the pictorial stimuli are converted into machine code data files and then used to create a rapidly changing display consisting of two or more line drawings. The latter stage could be accomplished in less than 2 msec but is limited by the frame time of the monitor (17–20 msec).  相似文献

Previous studies indicate that adolescents whose parents talk to them about sex tend to be less sexually active and more likely to use an effective means of contraception. This study sought to determine the relationship between parent-child communication about sex and young adolescents' reproductive and contraceptive knowledge and sexual attitudes. Twenty-two 12- to 14-year-olds and their parents completed sexual-knowledge, sexual-attitude, and contraceptive-choice questionnaires. Families were divided into high-communication and low-communication groups. There were no significant differences in the sexual knowledge, attitudes, or contraceptive choices of the children in the two groups, but the correlation between parents' and children's sexual attitudes in the high-communication group was significantly higher than that of the low-communication group. Although this was a correlational study, it seems likely that the similarity in sexual values was the result of parent-child discussion about sex.  相似文献

The purpose of this study was to ascertain which sex education topics parents of preadolescents regarded as appropriate for their children. The sample was comprised of 146 respondents randomly selected from a class list of sixth graders in a suburban school district. A mailed, self-administered questionnaire listing 48 possible topics was used to elicit parental response. Pretesting found the questionnaire to be highly reliable (Cronbach's alpha = .95). Overall, parents strongly supported the inclusion of a broad range of sex education topics regardless of parental age, sex, marital status, income, education, or child's sex. Moreover, parents were largely in agreement with the inclusion of sensitive topics in addition to those which were more physiological or behavioral. Catholics more often than Protestants agreed with the inclusion of birth control, abortion, and sterilization even after controlling for income and education. Thus, the findings suggest that parents of sixth graders find a broad sex education program in the school appropriate. To this end, school officials and sex educators should not overlook the needs of preadolescents for sex education solely on the basis of perceived parental opposition.  相似文献

The prevalence of DSM-III conduct and adjustment disorders in two adolescent psychiatric facilities, both located near large U.S. cities, was investigated. Overall, 31.6% of the adolescent inpatients were conduct disordered while 12.5% were adjustment disordered. The conduct disorders were primarily "aggressive" subtypes suggesting that this characteristic may influence hospitalization and diagnostic decisions. Such data on prevalence assists future treatment planning, allowing anticipation of case loads.  相似文献

Although there is extensive literature on the home environment as a socializing agent and on the perception of self and others, research relating home environment variables to adolescents' perception of themselves and others is not common. The present study, using a survey of 480 students, attempts to define and relate these two domains. Factor analyses of 16 semantic differential scales generated three dimensions--evaluation, understandability, and potency--for specifying attitudes toward self, parents, and certain external authority figures (teachers and police). In addition, factor analysis of 20 variables relating to adolescents' perception of their home environment suggested five factors: (1) extent of punishment, (2) amount of chores at home, (3) perceived parental control, (4) absence of parents, and (5) parents' attitude toward authority figures. Controlling for sex and age, these home environment factors were found to account for sizable portions of variance in certain components of the person perception domain. Particular relevance for several of these factors are discussed.  相似文献

Health needs and concerns of male adolescents   总被引:1,自引:0,他引:1  
W J Pinch  M Heck  D Vinal 《Adolescence》1986,21(84):961-969
Lifestyle factors established within the family help determine health-care functioning. Adolescents first may be challenged to meet their own health needs as freshmen in college. A 153-item questionnaire was utilized to examine concerns in the areas of alcohol and other drug use, auto safety, weight and dieting, smoking, sexuality, coping and stress, and selection and utilization of health-care services. One hundred fifty-nine male college students responded. Major problems with alcohol use, auto safety, weight control, stress and sexuality were identified. Positive lifestyle factors that were strongly supported included regular exercise, nonsmoking, regular medical and dental checkups, and the development of some support systems to cope with stress. Health-care services designated by respondents to meet their own needs were significantly different from those services they pointed out as needed for their peers.  相似文献

Factors associated with juvenile detention truancy   总被引:1,自引:0,他引:1  
Factors influencing truancy from a juvenile court treatment facility were investigated. Youth born in 1962 (N = 124) who were placed in the facility were compared for number of truancies, background, and personality variables. Results showed that males with prior adjudication for home or school truancy had a 65% probability of eloping from the court facility as compared to a 34% probability for youth adjudicated for other offenses. Most females were adjudicated for truancy offenses and showed a 62% probability of truancy while in the court facility. Further, for females who eloped and were returned, the probability of a subsequent truancy was above 80%. Personality characteristics of truants varied with sex: male truants were more likely to be conduct disordered youth for which impulsivity and disregard for social norms is prevalent; female truants appear more likely to be in conflict over autonomy issues.  相似文献
