The Revised UCLA Loneliness Scale (R-UCLA) is described and used as a unidimensional measure of loneliness; conceptualizing and assessing loneliness as a unitary, global experience. The present study suggests that the R-UCLA is a multidimensional measure of loneliness that assesses more than one construct of the loneliness experience. Results of principal axis factor analysis suggest that the R-UCLA measures three dimensions of loneliness: loneliness related to (a) “intimate others,” (b) “social others,” and (c) the “affiliative environment.” These findings may affect the utilization of the R-UCLA in future assessment, research, and intervention. These implications are discussed. This article is based on the author’s master’s thesis, submitted for the Master of Counseling degree at Arizona State University.  相似文献

This study examined the effects of neurolinguistic mirroring versus nonmirroring of selected nonverbal behaviors on empathy, trustworthiness, and positive interaction in a cross-cultural setting among 60 Choctaw adolecents and Caucasian female counselors. Results indicated significant mirroring effects on the empathy scale of the Barrett-Lennard Relationship Inventory.  相似文献

The arguments against doctors as "double agents" that are presented by Marcia Angell in the preceding article do not defeat the core justification for rationing some relatively high-expense, low-benefit care, and they do not enable us to conclude that clinicians should be barred from any active, substantive role in decisions to limit that care. They do, however, reveal several important conditions that need to govern cost-conscious medial practice in order to preserve an ethic of fidelity to patients: insurers' profits and providers' incomes must be fair, providers must inform patients of any economic reasons that lead to the foregoing of care, and "direct incentive" arrangements must not be used to contain costs.  相似文献

A critical problem in most real-time programming tasks is the verification that timing of the presented displays and recorded events occur at the expected times. It is often difficult for psychologists to verify critical timing because of the lack of costly specialized tools and technicians to measure events with millisecond accuracy. Algorithms utilized in a new Time Audit mechanism, added to the Micro Experimental Laboratory, are described. This new mechanism involves the recording and time stamping of all input and output events with 0.1-msec accuracy. This allows the experimenter to determine the initiation, duration, and termination of each event and also makes it possible to relate these events to the synchronization of the screen refresh cycle. A customized user interface provides a time log and event-tracing feature that enables nonprogrammers to determine the duration of command execution to the .1-msec level, allowing rapid, precise assessment of program execution. The resulting time log provides a detailed specification of the experimental events for debugging and a permanent record of the experimental procedure.  相似文献

If the phonological codes of visually presented words are assembled-rapidly and automatically for use in lexical access, then words that sound alike should induce similar activity within the internal lexicon.Towed is homophonous with TOAD, which is semantically related tofrog, andbeach is homophonous withbeech, which is semantically related totree. Stimuli such as these were used in a priming-of-namingtask, in which words homophonous with associates of the target words preceded the targets at an onset asynchrony of 100 msec. Relative to spelling controls (trod, bench), the low-frequencytowed and the high-frequencybeach speeded up the naming offrog andtree, respectively, to the same degree. This result was discussed in relation to the accumulating evidence for the primacy of phonological constraints in visual lexical access. nt]mis|This research was supported in part by National Institute of Child Health and Human Development Grants HD-08945 and HD-0 1994 to the first author and Haskins Laboratories, respectively.  相似文献

This paper reports on several patients who use sado-masochism as a defense against an unconscious wish for and fear of merging. The sado-masochism can be expressed as a sexual perversion or in a difficult ungratifying interpersonal relationship. These relationships have some of the quality of addictions in that the patients have a compulsive need to continue them and find it extremely difficult to leave them. Therapy must focus on helping the patient become more separate, rather than on other problems which may also be present. Initially, the therapist needs to take an educational stance in regard to the process the patient must complete, rather than the more traditional analytic stance.  相似文献

There have been continuing concerns about the extent to which maternal depression may influence maternal reports of child behavior. To examine this issue, a series of structural equation models of the relationships between maternal depression and errors in maternal reports of child behavior was proposed and tested. These models assumed that (a) maternal depression was unrelated to maternal reporting behavior; (b) maternal depression causally influenced maternal reporting accuracy; (c) maternal depression was correlated with reporting accuracy. These models were fitted to data on maternal depression and multipleinformant (mother, teacher, child) reports of conduct disorder and attention deficit behaviors for a birth cohort of 12 and 13yearold New Zealand children. The results of model fitting suggested the presence of small to moderate correlations (@#@ r=+.13 to+.40) between maternal depression and maternal reporting errors, indicating the presence of a tendency for increasing maternal depression to be associated with a tendency for mothers to overreport child behavior problems. However, independently of any effects of maternal depression on maternal reporting errors there was evidence of small but significant associations (r=.10 to .17; p<.05)between maternal depression and child conduct disorder and attention deficit behaviors.This research was funded by grants from the Health Research Council of New Zealand.  相似文献

The theoretical distinction between an articulatory control process and a short-term phonological store was supported in five experiments on immediate serial recall. In Experiment 1, articulatory suppression during the presentation and recall of auditory material abolished the word length effect but not the phonemic similarity effect. In Experiment 2, the two latter effects were found to be independent with auditory presentation. In Experiment 3, the effects of irrelevant speech and word length were found to be independent with visual presentation. In Experiment 4, articulatory suppression during the presentation and recall of auditory material abolished the phonemic similarity effect with a slow presentation rate. Nevertheless, in Experiment 5, articulatory suppression with a conventional presentation rate did not reduce the effect of phonemic similarity, even when a 10-sec interval was interposed between presentation and recall. These results indicate that the encoding, maintenance, and retrieval of spoken material within the phonological store do not depend on a process of articulatory rehearsal.  相似文献

The present study was designed to determine the main effects of alcohol intoxication on self-report and physiological measures of anxiety. Second, we aimed to assess the role of the Marlowe-Crowne Social Desirability (MCSD) scale in predicting the relationship between self-report and physiological indices of anxiety irrespective of drink content. A final purpose of the study was to determine whether the MCSD could account for discrepancies in the effects of alcohol on the two anxiety response systems. Subjects were male social drinkers who received an 0.70 g/kg dose of alcohol or placebo. Results indicated that irrespective of drink content, subjects with high MCSD scores reported lower levels of anxiety than did subjects with low MCSD scores. This relationship was not evident for heart rate. These results for measures of anxiety were not influenced by drink content.  相似文献

Previous work by Porac, Coren, and Searleman (1986) looked at overt attempts to change hand preference from the left to the right side. We extended this research by studying individuals who shifted their handedness from the left to the right side as well as a group who attempted a shift in the opposite direction (right to left). Comparisons of the two shift attempts revealed that the timing, method, and agent of change differed significantly for right versus left shifts. More right than left shifts were successful. Overall, most shift attempts were rated as unsuccessful because they did not result in a handedness classification consistent with the direction of the shift. Individuals classified as successful shifters, whether in the right or left direction, displayed a more ambihanded behavioural pattern than either unsuccessful shifters or the no shift control group. Evidence suggested that left-shift attempts were promoted by original ambihanded tendencies but that ambihandedness in successful right shifts stemmed from the partial success of the switch attempt.  相似文献
