It was hypothesized that gender differences in nonverbal behaviors which are often considered to be affiliative may represent systematic differences between males and females in self-presentation. Smiling, touching, and interpersonal distance were studied with 256 White adolescents and preadolescents, who were randomly assigned to same-sex grade-level pairs. Self-presentation was made more salient by asking each subject pair to pose for a picture depicting a social situation. Each pair illustrated one of two situations — a neutral situation and a “male-appropriate” situation that emphasized team spirit in an athletic competition. Girls smiled significantly more often than boys did and mutually touched each other more often, but there were no differences between the sexes in the overall amount of touching or proxemics. Instead, the social situation significantly determined the amount of touch and proxemics. Subjects' age and experimenter's sex were not significant variables.  相似文献

Adherence to dietary restrictions is a recurring problem for children on hemodialysis. The effect of behavior modification in maintaining dietary control is reported for four patients aged 11 to 18 years. Weight gain, potassium level, and blood urea nitrogen were utilized as criteria measures. A token reinforcement program implemented by the hemodialysis team resulted in significant changes in the dietary pattern of the children. The average weight gain between dialysis sessions for the four subjects during treatment was reduced by 45% and the degree of weight fluctuation was lessened. Potassium levels and BUN were controlled to their appropriate level for subjects who initially exceeded the criterion level. With the withdrawal of weight gain from the contingency system, increase of weight gain between dialysis sessions was noted for all subjects.  相似文献

The interrelations among measures of anticipation, recognition and savings are examined. It is shown that (a) the difficulty level of a recognition task can be above or below that of anticipation for the same material, and (b) the slope of retention curves based upon recognition measures may be more or less steep than the slope of curves based upon recall measures of the same material. Previous contrary conclusions reflect the exclusive use of easy recognition tests, and experimental designs in which the degree of learning is much greater for the recognition than for the recall task.  相似文献

The purpose of this study was to determine the impact of Project AWARE on children's attitudes about themselves, peers, teachers, principals, and school. Data were collected on children's sex, race, stanine score on achievement tests, and pretest performance in order to determine the differential effects of the treatment. Eighty students were included in the study, 40 in the experimental group and 40 in the control group. All were from fourth and fifth grade classrooms. The major findings were that children involved in the program achieved greater personal adjustment and accepted responsibility for negative outcomes in social situations (internal control). White children scored higher in personal and social adjustment. Black children evidenced more positive attitudes toward school. Girls scored significantly higher than boys on the social adjustment subtests and attitudes toward peers. Black children in the control group had less positive attitudes toward teachers than white children in the experimental group  相似文献

Adequately reading hyperactive boys, normally behaved learning-disabled (LD) boys, and normal controls were contrasted on tests measuring personality traits, cognitive role taking, and moral reasoning. Additionally, parents and teachers rated all children on a number of behaviors, and parents were interviewed in a process-oriented fashion to assess home stimulation potential. Hyperactive boys were rated more aggressive and anxious than LD boys and controls and had not been encouraged as much by parents to achieve. Hyperactives had been born to younger parents, on the average, and 25% lived with their mothers and stepfathers. None of the LD or control boys had stepfathers. The groups did not differ significantly in moral reasoning ability, cognitive role taking, or locus of control; on the Junior Personality Inventory hyperactives tended to have elevated scores on the neuroticism scale while LD boys had higher scores on the lie scale.This research was supported by Grant HDNS-09119 from the National Institute of Child Health and Human Development.  相似文献

Teen dating violence (TDV) is unstable across dating relationships, suggesting that characteristics of the relationship could be related to TDV. Few empirical studies have examined these links. This study examined associations between relationship characteristics and TDV perpetration among teens and sex differences in those associations. Relationship characteristics examined include tactics used to manipulate partners, ways of responding to relationship problems, relationship duration, exclusivity of the relationship, age difference between partners, and history of sexual intercourse with partner. Data were drawn from 667 teens in a current relationship (62.5% female and 81.4% White) enrolled in the 11th or 12th grade in 14 public schools in a rural U.S. state. Bivariate and multivariable regression analyses examined proposed associations. A total of 30.1% and 8.2% of teens reported controlling and physical TDV perpetration, respectively. In multivariable models, frequent use of manipulation tactics increased risk for controlling or physical TDV perpetration. Teens dating a partner 2 or more years younger were at significantly increased risk for both controlling and physical perpetration. A significant interaction emerged between sex and exit or neglect accommodation for physical TDV. Characteristics of a current dating relationship play an important role in determining risk for controlling and physical TDV perpetration.  相似文献
