Selected aspects of decision making in fertility behavior are reviewed. Attention is directed to assessing motivational determinants, the value of children, the concept of "wantedness," delayed childbearing, and adolescent fertility. A woman's decision to use or not to use a birth control method is heavily influenced by partner interaction. The perception of the partner's attitudes and degree of control in the couple relationship are likely to affect the type of method used, the consistency of contraceptive practice, and the resolution of eventual pregnancies. The present generation in many countries is the 1st to be involved in the conscious process of deciding when and how many children to have and to discontinue contraception. The psychosocial model of fertility behaviour emphasizes the subjective assessment of the environment by the individual and the importance of the 2 partners in a couple influencing each other's perceptions and choice behavior. A key feature of successful couple planning behavior is their joint ability to anticipate future outcomes, plan ahead, and develop contingency alternatives. The history of attempts to explain and delineate motivational determinants of fertility behavior is long and filled with testimonials regarding the complexity of the task. It has been well documented in cross-national studies and commentaries that the pleasures which parents experience in raising their children are highly valued. The gradual transition in the perceived economic value of children probably reflects changing parental attitudes accompanying the secular decline in fertility rates. Reducing the number of unwanted pregnancies has been and continues to be one of the major objectives of international planned parenthood and responsible parenthood movements. No published evidence exists, however, that the unexpected, unplanned, or even unwanted pregnancy is always "bad" or that a planned pregnancy more often produces a psychologically healthy child. To date research has been sparse on the effect of a 1st birth as a conditional factor influencing the number and spacing of subsequent births. Little attention has focused on the process of continuing employment and parenthood. Amid the generally falling birth rates for women under age 20, the number of births to women under age 16 has increased from approximately 25,000 in 1960 to 42,000 in 1977. In the U.S. adolescents bearing children are the least likely to receive adequate prenatal care, are most at risk for having a low birth weight baby, and are more exposed to complications of labor and delivery. 相似文献

This paper concerns the differential effects of use of ‘thematic’, rather than abstract (symbolic), content on the ‘Wason
selection task’. An effect of thematic content has been reported several times, originally by Wason & Shapiro (1971), but
Manktelow & Evans (1979) report five experiments that failed to obtain an effect and argue against the validity of the content
effect in general. However, it is pointed out that four of their experiments use a novel content and that there are previous
reports of non-effective content in the literature. It is concluded that a particular type of thematic content cannot be treated
as a ‘random sample’ of thematic content in general, and that their argument thus rests upon their failure to produce an effect
of the specific (’towns and transport’) content used by Wason and Shapiro. This produces an essentially empirical controversy
which is settled in two ways. First, Manktelow and Evans’s criticisms of two previous replications are shown to be misleading.
Second, an experiment is reported that exactly copies the Wason and Shapiro design and produces a significant effect of content.
It is concluded that the Manktelow and Evans result most probably was due to a Type 2 error. Finally, a hypothesis is developed
to account for both the effect of certain types of content and the lack of effect of others, including that used in Manktelow
and Evans’s first four experiments. 相似文献

Eysenck originally postulated that extraverts would adopt tough-minded social attitudes, although psychoticism is now considered
to be of greater importance than extraversion. Previous research has attempted to relate psychoticism to realism-idealism,
a principal factor of the Wilson-Patterson Conservatism Scale, and a measure of tough-mindedness acceptable to Eysenck. Results
have proved discrepant; authors have used psychoticism scales of uncertain item content and length. The present study examines
the relationship between psychoticism, extraversion and realism-idealism, using the Eysenck Personality Questionnaire and
the Wilson-Patterson Attitude Inventory. The results provide only weak support for Eysenck’s theory. A more significant relationship
was obtained between psychoticism and conservatism, and extraversion and conservatism, although a theoretical rationale for
these relationships is lacking. 相似文献

Reviews measurement approaches applied to dream reports and proposes some methodological cautions that may result in more effective utilization of the dream report in research and assessment. Standardization of dream collection techniques and controls for variability in the length of dream reports are suggested. Further investigation of the intraindividual consistency of dream report measures is seen as necessary for a discussion of their validity. Though there are indications that a variety of dream report measures are potentially valid for psychological assessment, measures based on general dream report characteristics show greater promise than specific content analysis. Research on the differences between normal and disturbed subjects highlights the potential, and the problems, inherent in the use of dream reports as tools of psychological inquiry. 相似文献

The resistance of the Personal Orientation Dimensions (POD) to deliberate attempts at creating a favorable impression was investigated. Two groups of college students were used: (a) 21 students completed the POD under standard instructions, then received information about actualization, and completed the POD again under instructions to Create a very good impression; (b) 21 students completed the POD under standard instructions, then received information not related to actualization, and completed the POD again under instructions to create a very good impression. An analyses indicated that providing students with information about actualization did not facilitate their ability to create a favorable impression on the POD. The POD profiles produced by both groups changed significantly, and in a similar direction from pretest to posttest. Evidence is presented suggesting the existence of a "lie profile" which distinguishes deliberate attempts to create a favorable impression on the POD. These findings provide support for the resistance of the POD to deliberate attempts at creating a favorable impression. 相似文献

Rats were trained to bar-press for water in the presence of a simultaneous compound tone-light stimulus using a discrete-trial procedure. Different groups were given between 300 and 3900 trials. When subsequently tested in extinction, all rats showed consistent levels of responding to the compound stimulus but responding to the tone and light components declined as a function of number of training trials. This is a demonstration of spontaneous configuring. Two other experiments showed that with similar procedures generalization from a component of the training stimulus to other values on the same continuum decreases with increased training with the compound stimulus. It was concluded that configuring and generalization from a single stimulus involve the same processes. 相似文献

Concurrent fixed-interval variable-ratio schedules and the matching relation 总被引:5,自引:5,他引:0 下载免费PDF全文

Five rats responded under concurrent fixed-interval variable-ratio schedules of food reinforcement. Fixed-interval values ranged from 50-seconds to 300-seconds and variable-ratio values ranged from 30 to 360; a five-second changeover delay was in effect throughout the experiment. The relations between reinforcement ratios obtained from the two schedules and the ratios of responses and time spent on the schedules were described by Baum's (1974) generalized matching equation. All subjects undermatched both response and time ratios to reinforcement ratios, and all subjects displayed systematic bias in favor of the variable-ratio schedules. Response ratios undermatched reinforcement ratios less than did time ratios, but response ratios produced greater bias than did time ratios for every subject and for the group as a whole. Local rates of responding were generally higher on the variable-ratio than on the fixed-interval schedules. When responding was maintained by both schedules, a period of no responding on either schedule immediately after fixed-interval reinforcement typically was followed by high-rate responding on the variable-ratio schedule. At short fixed-interval values, when a changeover to the fixed-interval schedule was made, responding usually continued until fixed-interval reinforcement was obtained; at longer values, a changeover back to the variable-ratio schedule usually occurred when fixed-interval reinforcement was not forthcoming within a few seconds, and responding then alternated between the two schedules every few seconds until fixed-interval reinforcement finally was obtained. 相似文献

Separate factor analyses of responses to the Tennessee Self-concept Scale using item and scale data are reported for a sample of 255 disabled veterans. A global self-satisfaction factor and several subsidiary factors roughly approximate the external dimension of the scale. The internal dimension interacts with the external one in defining several factors but does not emerge as an independent dimension. Scale data yield a self-esteem factor incorporating both external and internal scales and a self-concept conflict-integration factor. The evidence supports the external dimension more than the internal dimension. The findings are consistent with previous studies that have not validated the two-dimensional design of the scale. 相似文献

A clarification of some of the roots of marital breakdown is sought through examining the love relationship in Viktor Frankl's logotherapy and its theological counterparts in Judaism. Frankl's implicit ethic of self-transcendence coincides with Judaism's view of the married state as shared destiny. Together these call into question the ethic of self-fulfillment which appears to underlie much marital distress.Dr. Bulka is Rabbi of Congregation Machzikei Hadas in Ottawa, Ontario, and Editor of theJournal of Psychology and Judaism.
