Two experiments investigated home-based reinforcement contingencies to control excessive behavior in normal classrooms. Subjects were, respectively, a 12-yr-old fifth-grade boy and a 9-yr-old fourth-grade boy, each in a separate classroom and with a different teacher. Following baseline observations in which observers recorded several categories of student behavior and teacher-student interaction, separate conferences were held including parents of the two children, the principal, teachers, and experimenters. A daily report-card procedure was agreed on, stipulating a one-day suspension from school following three successive “undesirable” daily report cards as well as the supervision of home-based privileges and other reinforcers usually contingent on satisfactory daily reports. Measurements of daily rates of teacher attention indicated no important change in this variable throughout the various experimental conditions. The daily report procedure significantly reduced disruptive classroom behavior. In a second experiment, a teacher-operated timer cued her own time-sample observations. Reliability measures revealed that the teacher could accurately measure the child's behavior while she was teaching the class. The procedure was ultimately successfully expanded to the teacher's total contact hours each day.  相似文献

The language development of three 9- and 10-year-old children possessing only a right or a left hemisphere was studied. Surgical removal of one brain half antedated the beginning of speech, so each child has acquired speech and language with only one hemisphere. Different configurations of language skill have developed in the two isolated hemispheres: phonemic and semantic abilities are similarly developed but syntactic competence has been asymmetrically acquired. In relation to the left, the right brain half is deficient in understanding auditory language, especially when meaning is conveyed by syntactic diversity; detecting and correcting errors of surface syntactic structure; repeating stylistically permuted sentences; producing tag questions which match the grammatical features of a heard statement; determining sentence implication; integrating semantic and syntactic information to replace missing pronouns; and performing judgments of word interrelationships in sentences. Language development in an isolated right hemisphere, even under seizure-free conditions, results in incomplete language acquisition.  相似文献

ABSTRACT: In an attempt to determine the extent to which crisis centers meet the needs of black communities, questionnaires were sent to 12 centers. Responses were received from six. Only two centers, in Nashville and Washington, D.C., had statistics of callers identified by race. The findings from these two centers indicate that there are differences between the white and black callers with regard to age, marital status, and type of problem. As an example, the typical black male caller was older and more concerned about his job and financial problems than were white males. This kind of information suggests a need for expanded services within the crisis center framework, possibly for a more preventive approach. More data gathering concerning the black community using crisis centers is urged in order better to identify the needs of this population and the methods to be used for meeting those needs.  相似文献

The transition to parenthood is one of the most stressful intra- and interpersonal adjustment periods for new parents. Bidirectional associations among intergenerational relationships during the transition to parenthood have received limited attention, and the complexity of reciprocal relationships varies in accordance with living arrangements. The objectives of this study were to explore (1) the bidirectional associations between marital relationships and conflicts with in-laws during the transition to parenthood and (2) the moderation of patrilineal coresidence on the aforementioned relationships. A three-wave prospective longitudinal design was adopted for 359 married mothers. The Dyadic Adjustment Scale and Stryker Adjustment Checklist were used to assess marital relationships and conflicts with parents-in-law. Cross-lagged panel analysis was applied to examine reciprocal relationships, and multigroup analyses were employed to determine whether these relationships exhibited different patterns in accordance with the individuals’ living arrangements. The two cross-lagged models revealed the presence of a bidirectional relationship between marital distress and conflicts with parents-in-law during the mid- to late pregnancy stages. Meanwhile, the multigroup analyses suggested that conflicts with parents-in-law triggered marital distress during pregnancy in the coresidence group, whereas conflicts with fathers-in-law could intensify marital distress during late pregnancy to the postpartum period in the noncoresidence group. These findings shed light on cross-lagged associations with intergenerational conflicts. Healthcare professionals need to ensure that intergenerational relationships are positive during the transition to parenthood. This study enriches our understanding of the effect of patrilineal coresidence and can guide the future development of interventions based on culturally specific multidimensional approaches.  相似文献
