One hundred and twenty-two pairs (n = 244) of caregiver daughters and care recipient mothers were interviewed individually to investigate the factors underlying positive, adaptive eldercare relationships. The 2 eldercare outcome variables examined were caregiving pairs' degree of congruency in role expectancies and perceived personal growth and an enhanced understanding of personal aging (self, other) through the caregiving experience. Participants were also categorized by caregiving pair type (e.g., positive), derived from blind ratings of participants' responses. Factors examined as being significant predictors of these 2 outcome variables for both caregivers and care recipients were perceived relationship roles (perceived role changes, perceived role relations) and individual-difference characteristics (big five personality dimensions, fluid intellectual ability). Path analysis results supported the importance of both role-related and individual-difference factors in understanding what works. Further, the need to differentiate between the perceptions and motivations of caregivers and care recipients is supported by the present research findings. 相似文献

We used previously refused foods as positive and negative reinforcement in the acquisition of cup drinking. Cup drinking increased with positive and negative reinforcement, both alone and in combination (without escape extinction), indicating that treatment of food refusal can establish some foods as appetitive stimuli whereas others remain aversive. 相似文献

Variable-interval reinforcement schedule value influences responding following REM sleep deprivation 下载免费PDF全文
The effects of rapid-eye movement sleep deprivation (REMSD) in rats were studied in relation to variable-interval (VI) reinforcement schedule value. Initially, lever pressing was maintained on a VI 30-s schedule of food pellet delivery. After a baseline was established, rats were repeatedly exposed to 96 hr of REMSD and control conditions of an equivalent duration. Responding decreased following REMSD but not after exposure to control conditions. Lever pressing was then maintained on a VI 15-s schedule of food pellet delivery and exposure to the REMSD and control conditions was repeated. Under this condition following repeated REMSD exposures, rates of lever pressing became similar to baseline responding. A VI 30-s schedule of food pellet delivery was then reinstated and REMSD and control conditions were repeated. Lever pressing following exposure to the REMSD condition decreased for 3 of 4 rats. Results suggest that VI schedule value influences the effects of REMSD on responding. 相似文献

In 1948, Skinner described the behavior of pigeons under response-independent schedules as “superstitious,” and proposed that the responses were reinforced by contiguous, adventitious food deliveries. Subsequently, response-independent schedules have been of interest to both basic and applied researchers, first to understand the mechanisms involved, and later, as “noncontingent reinforcement” (NCR) to reduce undesirable behavior. However, the potential superstitious effects produced by these schedules have been challenged, with some researchers arguing that antecedent variables play a significant role. This paper examines the evidence for adventitious reinforcement from both laboratory and applied research, the results of which suggest that antecedent, nonoperant functions may be important in fully understanding the effects of NCR. We propose an applied-basic research synthesis, in which attention to potential nonoperant functions could provide a more complete understanding of response-independent schedules. We conclude with a summary of the applied implications of the nonoperant functions of NCR schedules. 相似文献

We evaluated the effects of an enriched environment, based on a paired-choice preference assessment, on both rates of self-injurious behavior (SIB) and percentage of session intervals during which signs of negative affect were displayed by a woman with mental retardation and a mood disorder. Results suggested that SIB and signs of negative affect were highly correlated and that the enriched environment effectively reduced both. 相似文献

Recently, Feferman and Hellman (and Aczel) showed how to establish the existence and categoricity of a natural number system by predicative means given the primitive notion of a finite set of individuals and given also a suitable pairing function operating on individuals. This short paper shows that this existence and categoricity result does not rely (even indirectly) on finite-set induction, thereby sustaining Feferman and Hellman's point in favor of the view that natural number induction can be derived from a very weak fragment of finite-set theory, so weak that finite-set induction is not assumed. Many basic features of finiteness fail to hold in these weak fragments, conspicuously the principle that finite sets are in one-one correspondence with a proper initial segments of a (any) natural number structure. In the last part of the paper, we propose two prima facie evident principles for finite sets that, when added to these fragments, entail this principle. 相似文献

This study examined the degree of independence between Positive Affect (PA) and Negative Affect (NA) within a given situation. The affective state was measured before and after an experimentally induced success or failure experience in an anagram task. Two types of affect measures were used to assess PA and NA: the Positive and Negative Affect Schedule (PANAS) and a Pleasantness-Unpleasantness scale. Consistent with our hypotheses, results show that PA and NA are independent when measured with the PANAS but are correlated when assessed with the other scale. These PA-NA correlations differed significantly from each other before and after emotion induction, respectively. Additional analyses indicate that both PA scales are differentially sensitive to the mood induction procedure. The findings are discussed with respect to circumplex models of emotion. 相似文献

The present study was designed to assess whether certain contexts influenced material reactions to children's compliant and noncompliant behavior. Study 1 examined the following contextual variables: chronic negative conditions of the child (physical illness and psychological disturbance) and recent life events experienced by the child (both positive and negative). Study 2 examined maternal mood states as another contextual variable. Results indicated that these contexts relate to differential choices of discipline techniques, based on maternal self-report. These data are examined in light of the literature on treatment acceptability and are discussed in terms of a signal-detection model. Clinical applications are addressed, and suggestions for future research are offered.Portions of this paper were presented at the meeting of the Association for Advancement of Behavior Therapy, Philadelphia, November 1984.We express gratitude to the Research Council of the University of North Carolina at Greensboro for Research Council Grant 2110 218 00000 7719 and to the following for their assistance: James Herbert, Nancy Quinn, Carol Roberson, Ira Turkat, and Marilyn Williams. 相似文献

Enhancing social relationships through positive psychology activities: a randomised controlled trial
Brenda H. O’Connell Deirdre O’Shea Stephen Gallagher 《The journal of positive psychology》2016,11(2):149-162
Despite the robust relationship between well-being and social relationships, the latter has received little examination within positive psychology activities (PPAs). This study aimed to test whether kindness- and gratitude-based PPAs, through positive social interaction with peers, enhanced relationship satisfaction. Using a longitudinal randomised controlled design, 225 participants were assigned to one of three conditions (relationship-focused, self-focused or control) and completed measures of relationship satisfaction, social support and happiness on three occasions (baseline, post-intervention and six weeks). The experimental PPAs were relationship-focused (involving social interaction) or self-focused (no social interaction). Those who completed relationship-focused PPAs had greater increases in relationship satisfaction than the self-focused and active control activities at six-week follow-up. Additionally, only those in the relationship-focused condition felt their existing friendships had improved at intervention cessation. Regardless of participants’ initial levels of social support, the intervention effects remained. In conclusion, PPAs fostering social kindness and gratitude significantly strengthened relationship satisfaction. 相似文献
