This investigation was undertaken to determine the effects of differing levels of treatment integrity resulting from implementation of varying numbers of intervention components. The self-monitoring program was conducted over 4 weeks and targeted positive and negative classroom behaviors. The independent variable included three levels: 100% integrity, that included reward and graphing of behavior; 83.3% integrity, that included the reward component; and 66.7% integrity, that employed self-monitoring with recording only. Participants included 49 elementary school students, mean age of 10.4 years, 36.7% female, 93.9% Anglo. Results of treatment on teacher and student ratings from the Social Skills Rating System, teacher ratings from the Abbreviated Symptom Questionnaire, ratings of the child-specific target behaviors, and student frequency counts of target behaviors were analyzed using Multivariate Analyses of Variance. The changes in rating measures from pre-test to post-test did not significantly differ between groups. Students in the two more inclusive treatment programs recorded more positive behaviors.  相似文献

The Weber fraction, (I + Δ)/I, was measured for pure tones which were I presented either homophasically or antiphasically. For both stimuli, the Weber fraction was measured as a function of changes in the level of the standard tone Iand in the phase angle of addition between a test tone and the standard tone. The value, ΔI, in the Weber fraction was defined as that difference between the level of the test-plus-standard and the level of the standard (I) which was required for the listener to discriminate a difference between the standard and the test-plus-standard. In the homophasic case, the Weber fraction remained constant for changes in the phase angle of addition, whereas in the antiphasic condition, the Weber fraction decreased for increasing values of the phase angle of addition. For both the homophasic and antiphasic conditions and at all values of the phase angle of addition, the Weber fraction remained a constant as the value of the standard was varied. These results are in agreement with those obtained in studies involving noise masking, lateralization, and the monaural Weber fraction.  相似文献

Motion parallax is a composite of five transformations demonstrated to be effective in adult judgments of rotation direction in polar motion projections of a horizontal row of dots rotating in depth. The effectiveness of these transformations as a function of age was tested by presenting six such motion projections to first graders (age = 6 years), seventh graders (age = 13 years), and college students (age = 19 years). Identical age functions were obtained for judged rotation direction from the four motion projections representing (1) Velocity, corresponding to the traditional definition of motion parallax as differential velocity, (2) Velocity plus differences between ratios of instantaneous displacement to instantaneous acceleration for dots on the near and far sides of the rotation axis (DA Difference), (3) Velocity, DA Difference, and a gradient across the row of DA ratios, and (4) all transformations. First graders, unable to use horizontal transformations, performed at chance on these four projections, while older students made correct judgments. Order, separated from Velocity for the first time, resulted in chance performance at all ages, while Direction, also separated from Velocity for the first time, resulted in veridical judgments in only 4 of 24 college students.  相似文献

Absenteeism rates of industrial employees (N = 21) referred by their employers to alcoholism treatment were evaluated during three phases: pre-treatment (the 24 months immediately prior to treatment); treatment (the period of continuous treatment enrolment, averaging 10.6 months); and post-treatment (the period immediately following treatment, averaging 4.4 months). Treatment consisted of disulfiram maintenance—routine supervised ingestion of disulfiram—without scheduled counseling. The median per cent of scheduled work days absent for each phase was: pre-treatment, 9.8%; treatment, 1.7%; post-treatment, 6.7%. Absenteeism during the treatment phase was significantly less (p < 0.01) than that during pre-treatment and post-treatment, which did not differ significantly from one another. The five-fold reduction in absenteeism was specifically related to treatment delivery, and appears superior to the two-fold reduction reported for traditional employee alcoholism treatment via counseling.  相似文献

Unwilling versus unable: infants' understanding of intentional action   总被引:1,自引:0,他引:1  
Infants experienced a female adult handling them toys. Sometimes, however, the transaction failed, either because the adult was in various ways unwilling to give the toy (e.g., she teased the child with it or played with it herself) or else because she was unable to give it (e.g., she accidentally dropped it). Infants at 9, 12, and 18 months of age reacted with more impatience (e.g., reaching, looking away) when the adult was unwilling to give them the toy than when she was simply unable to give it. Six-month-olds, in contrast, showed no evidence of this differentiation. Because infants' behavioral responses were appropriately adapted to different kinds of intentional actions, and because the adult's actions sometimes produced results that did not match her goal (when having accidents or failed attempts), these findings provide especially rich evidence that infants first begin to understand goal-directed action at around 9 months of age.  相似文献

Masculine gender role stress is a theoretical construct that describes the stress created in men when they feel they are not meeting society's expectations for masculinity, or when the situation forces men to act in feminine-typed ways. The stress produced by these feelings or actions are thought to be related to negative psychological outcomes for men, but should be unrelated to well-being for women. The present study investigated the validity of the masculine gender role stress construct, especially with regard to the assumption that masculine gender role stress is related to negative psychological outcomes for men more than for women. Participants were a group of mostly Caucasian undergraduates. Results indicated that masculine gender role stress was related to depression, hostility, and anxiety, but to the same degree for both men and women. These findings suggest that, if MGRS is a valid construct, then researchers need to explore other ways in which this type of stress can negatively affect men, but not women.  相似文献

The present study was designed to test the prediction from the attention-allocation model that intoxication in the absence of a pleasant distractor will fail to produce anxiolytic effects. A second prediction, that the sequence of intoxication and exposure to the anxiety-producing situation would influence alcohol's effects, was also tested. Subjects were male social drinkers who received an 0.85 g/kg dose of alcohol or a placebo. Conventional statistical analysis of the results indicated an anxiolytic effect of alcohol on heart rate but a problem with this analysis is identified. An alternative interpretation provides no support for an anxiolytic effect. Exposure to the anxiety-producing stimulus prior to intoxication led to greater heart rate reactivity than if it followed intoxication.  相似文献
