In three experiments rats received training in a straight alley under high hunger and then were tested satiated. Both eating and running continued to occur under satiation, but the two responses were not completely correlated, and continued running did not depend upon continued eating. Further, groups differed in their eating behavior, although all experienced the same satiation procedure, suggesting that eating under satiation is not just a reflection of incomplete satiation. Resistance to satiation of the running response was greater following partial reward than following consistant reward and tended to be greater following small reward training than large reward training, regardless of schedule of reward. Eating during satiation was greater following partial than following consistent reward and was greater if the same reward magnitude was given in satiation as in acquisition than if a different reward magnitude was given. It was suggested that resistance to satiation is an associative phenomenon. Eating and running occur during satiation because the stimuli present during satiation continue to elicit them. The differences between results using rewarded satiation and results using high drive extinction as measures of persistence were attributed to satiation being nonfrustrating.  相似文献

College students (122 males and 88 females) completed the Group Embedded Figures Test measure of field-dependence, and Sensation-Seeking Scale, and performed preference ratings on 40 slides of paintings. Factor analysis revealed six hypothesized and one unhypothesized preference dimensions that underlay preference ratings of paintings. It was hypothesized that the cognitive structuring ability associated with field-dependence would result in certain relationships between field-dependence and preference for paintings. Further, it was hypothesized that preference for novel, complex, and dynamic experiences, associated with sensation-seeking, would result in certain relationships between sensation-seeking and preference for paintings. For the full sample, three of five hypothesized relationships between field-dependence and preference for paintings were obtained, while three of four hypothesized relationships were found between sensation-seeking and preference for paintings.  相似文献

Historically more attention has been focused on the adult stutterer than on the young stutterer. This article discusses three key issues in the differential diagnosis of normal childhood nonfluencies and childhood stuttering. The three issues are (1) whether early childhood disfluencies are heterogeneous or homogeneous phenomena, (2) whether the relationship between normal childhood nonfluencies and early stuttering is continuous or dichotomous, and (3) whether normal nonfluencies and stuttering differ quantitatively or qualitatively. Theoretical research as well as clinical implications of these issues are discussed.  相似文献

The purpose of this study was to investigate the relationship between dispositional optimism, dispositional pessimism, repressive coping and trait anxiety. The Marlowe-Crowne scale (MC) and the Bendig version of the Taylor Manifest Anxiety Scale (MAS) were used to select repressor and control groups (N=143, aged between 18 and 47 years), who subsequently completed a measure of dispositional optimism, the Life Orientation Test (LOT), which consists of two sets of items: optimism and pessimism. Repressors (high MC, low MAS) reported significantly lower pessimism than all other participants. When the pessimism scale was divided into high and low categories, there were significantly more repressors in the low pessimism group than the other low trait anxiety group, low anxious (low MC, low MAS). However, for the optimism scale the opposite pattern of results was found, with significantly more low anxious in the high optimism group than repressors. These results support the assertion that the pessimism and optimism scales of the LOT are not the same construct and should be measured separately.  相似文献

The extent to which practicing professional counselors perceive themselves as multiculturally competent and the basis for their training experiences in multicultural counseling have not been determined. This article reports the results of a survey on practicing professional counselors' perceptions of their multicultural competence and the nature of their pre- and in-service professional preparation in this area. There was no significant difference in self-perceived multicultural competence between graduates of Council for Accreditation of Counseling and Related Educational Programs (CACREP) accredited and nonaccredited programs. However, ethnicity was related to higher levels of perceived multicultural competence.  相似文献

The present studies were designed to evaluate methodological influences on the efficiency of genetic-screening studies, specifically when enrolling preschoolers in a prevalence study of the fragile X full mutation. The studies include replication of earlier findings with school-age children, which showed that (a) a higher enrollment rate occurred when the study was introduced to a parent by a physician (73.7%) versus by a research assistant (58.7%), and (b) parents initially undecided about participating were more likely to eventually enroll if they had completed enrollment forms at the time of recruitment, In-person recruitment led to higher enrollment rates (60%) than did recruitment by mail (36.8%). Feedback from parents indicated the importance of emphasizing the optional nature of participation in screening studies.  相似文献

Remarriage of parents may bring new grandparents and stepgrandparents into the lives of children, creating new family structures and needs for adjustment. The extended-blended family may benefit from specific counseling interventions.  相似文献

The effects of experimental history on responding under a progressive-ratio schedule of reinforcement were examined. Sixteen pigeons were divided into four equal groups. Groups 1 to 3 were trained to peck a key for food under a fixed-ratio, variable-ratio, or differential-reinforcement-of-low-rate schedule of reinforcement. After training, these pigeons were shifted to a progressive-ratio schedule, later were shifted back to their original schedule (with decreased rates of reinforcement), and finally were returned to the progressive-ratio schedule. Pigeons in Group 4 (control) were maintained on the progressive-ratio schedule for the entire experiment. To test for potential "latent history" effects, pigeons responding under the progressive-ratio schedule were injected with d-amphetamine and given behavioral-momentum tests of prefeeding and extinction. Experimental histories affected responding in the immediate transition to the progressive-ratio schedule; response rates of pigeons with variable-ratio and fixed-ratio histories were higher than rates of pigeons with differential-reinforcement-of-low-rate and progressive-ratio-only histories. Pigeons with differential-reinforcement-of-low-rate histories, and to a lesser degree pigeons with variable-ratio and fixed-ratio histories, also had shorter postreinforcement pauses than pigeons with only a progressive-ratio history. No consistent long-term effects of prior contingencies on responding under the progressive-ratio schedule were evident. d-Amphetamine and resistance-to-change tests failed to reveal consistent latent history effects. The data suggest that history effects are sometimes transitory and not susceptible to latent influences.  相似文献

Structural Equation Modeling techniques were used to clarify the relationship between marital characteristics, marital processes, and the dependent variable—marital satisfaction—in a sample of 201 participants who were in 1st marriages. The Dyadic Adjustment Scale (DAS; G. B. Spanier, 1976) and the Enriching and Nurturing Relationship Issues, Communication and Happiness Inventory (ENRICH; D. H. Olson, D. G. Fournier, & J. M. Druckman, 1987) provided scales to measure marital interaction processes and marital satisfaction. A new instrument, the Characteristics of Marriage Inventory (CHARISMA; J. R. Rosen‐Grandon & J. E. Myers, 2001), was developed using factor analysis to determine which marital characteristics were statistically significant. Structural equation modeling identified a path model wherein 6 marital interaction processes had a statistically significant influence on marital satisfaction when mediated by 3 latent factors of marital characteristics (love, loyalty, and shared values) and 2 moderating variables (length of marriage and gender of participant).  相似文献
