The issue of multiple memory systems is explored. Young and older adults (mean ages = 20 and 71, respectively) named pictures and were tested immediately, 1, 7, or 21 days later. Episodic memory (recognition) for pictures was significantly lower in older relative to young adults and declined systematically across all retention intervals in both age groups. In contrast, procedural memory (repetition priming in picture naming) revealed no reliable age differences. In both age groups, priming declined within the first 24 hr, but unlike recognition, there was no further decrement from 1 to 21 days. There were also within-subject dissociations: The magnitude of priming was equivalent for remembered and forgotten items, and the relation between recognition and priming across intervals was nonmonotic, revealing a reversed association. The findings were interpreted within a multiple-memory-systems framework.  相似文献

The development of consultation skills lags far behind the development of counseling skills in most counselor education programs. Some of the reasons why consultation training is not emphasized are examined, and some remedies are suggested.  相似文献

In an attempt to account for morale and job satisfaction among 314 nurses, this study investigated the influence of work-related and interpersonal variables. Morale on the unit was directly related to supervisor support, co-worker relationships, and work recognition. Personal morale was accounted for by recognition, physical environment, the job itself, and pay. Job satisfaction was predicted by personal morale, work commitment, job clarity, work pressure, and innovation. Suggestions for improving nurse morale and job satisfaction are made.  相似文献

A major criticism of research on body image concerns the dubious assumptions of the unidimensionality of the construct and the equivalence of body-image measures. Our study of 125 male and female college students compared multiple measurement methods within each of two modalities of body image: (a) perceptual (body-size estimation) and (b) attitudinal (body-image affect and cognition). Clinically relevant indices of psychological adjustment and eating disturbance were included. Results clearly supported the distinction between attitudinal and perceptual modalities of body image and indicated more convergent and discriminant validity for the former than for the latter. Whereas one method of assessing size-estimation accuracy and most body-image attitudes produced relationships with maladjustment, only attitudinal body image and perceptual, self-ideal discrepancy measures were significantly linked to eating disturbance. Relationships were generally more consistent for women than for men. Implications are discussed in the context of extant and future research on body image with clinical and nonclinical populations.  相似文献

Proofs and Refutations is Lakatos's masterpiece. This article investigates some of its central themes, in particular: the nature of proofs ('Proofs do not prove, they improve'); the nature of definitions (real, not nominal); and the consequences of all this for ontology (platonism vs Popper's World Three).  相似文献

Summary When a line (the pointer) is collinear with a dot, the addition of a second line (the induction line) contiguous with the dot or near it may cause the pointer to appear to be collinear with a point further along or nearer to the induction line. The geometrical relations upon which this effect, which we call attraction-caused misalignment, depends have been studied with the Obonai and Wundt-Loeb (Hotopf, 1981; Hotopf & Brown, 1988) figures. Drawing upon the studies of misalignment in the Morinaga figure carried out by Restle (1976), Day, Bellamy, and Norman (1983), and Day and Kasperczyk (1985), as well as upon two new experiments, we show that misalignment in the Morinaga figure is also attraction-caused misalignment, as previously defined. We conclude with a discussion of a number of theories that aim at accounting for attraction misalignment.  相似文献
