Three experiments were conducted to examine age differences in memory for telephone numbers by adults ranging from 18 to 85 years of age. In the first 2 studies, using visual simultaneous presentation, age declines in immediate recall were evident on 10-digit numbers, but not on 3-digit numbers. With 7-digit numbers, the youngest group performed significantly better than the oldest (70-85 years) group. In the second study, more marked age declines occurred when subjects had to redial a number after a busy signal. The third experiment replicated the observed aging pattern with auditory sequential presentation. Also, chunked presentation of local telephone numbers resulted in high performance for old and young in sequential recall. The findings were discussed in relation to task processing demands and practical issues related to telephone number recall.  相似文献

The size of the perceptual unit used in reading was addressed using the predesignated target paradigm. Sixteen subjects viewed the following stimuli in random order: the words tee, the, tie, and toe; the nonwords eet, eht, eit, and eot; and the letters e, h, i, and o. Subjects fixated on the location of the center letter and identified the letter as e, h, i, or o, alternatives which were known to them at the onset. A word superiority effect was obtained for the common word the but not for the less common words tee, tie, and toe. The word superiority effect was attributable to bias rather than discriminability: Subjects exhibited a bias to perceive the words in this experiment as the (i.e., there was a bias to perceive h in the t e stimulus presentations). These results suggest that the common word the is processed in reading units that are larger than the letter, and that the system is biased to perceive common rather than uncommon words in data-limited conditions.  相似文献

Height vertigo (acrophobia) is a very frequent phenomenon being of interest for its physiological and psychological background, though usually only of limited significance in neuropsychiatry and otology. The different aspects as to its nature and origin are discussed. If acrophobia has developed into a conditioned reaction of avoidance with pressure of suffering, or acrophobia in persons, who have to work at heights, behavior therapeutic measures with systematic desensibilisation, starting from an imaginative training, are indicated.  相似文献

The Sheltered Care Environment Scale (SCES) was developed primarily to measure social climate as an attribute of a setting. As such, the SCES was designed to maximize differences between facilities and minimize differences among individuals within a setting. However, Smith and Whitbourne (1990) assessed the validity of the SCES as a measure of individual differences in perceptions of a shared environment. Moreover, they redefined the content coverage of 2 of the SCES subscales (Independence and Physical Comfort), to encompass attributes the SCES is not intended to measure. In general, preliminary evidence indicates that the SCES subscales provide reasonably reliable and valid indices of the social climate of group residential facilities.  相似文献

Fifteen Type I diabetic patients self-monitored daily mean blood glucose levels (BGL), psychological stress, diet, exercise, and insulin injections for a period of 8 weeks. Separate multiple-regression analyses were conducted for each subject to assess the predictability of BGL from stress reports, independent of the effects of diet, exercise, and insulin self-administration. Considerable individual variability in findings was evident, with stress predicting BGL in a statistically significant manner in 7 of the 15 subjects. Stress had a significant effect on BGL independent of diet, exercise, and insulin administration for each of these 7 subjects. Discussion focused on the problems of measuring the key self-management behaviors influencing BGL and on the possibility that a subgroup of diabetic patients may be BGL stress responders.  相似文献

Monocular stereopsis with and without head movement   总被引:2,自引:0,他引:2  
Random dots moving with various velocity gradients were presented to observers; the motion was yoked to head movement in one condition and to no head movement in another. In Experiment 1, 12 observers were shown motion gradients with sine, triangle, sawtooth, and square waveforms with amplitudes (equivalent disparities) of 12' and 1 degrees 53'. In Experiment 2, 48 observers were shown only the sinewave or square-wave gradient of 1 degrees 53' disparity either with or without head movement so that the observers' expectation to see depth in one condition did not transfer to another. The main findings were: (1) with 12' disparity, the head-movement condition produced perceived depth but almost no perceived motion, whereas the no-head-movement condition produced both perceived depth and perceived motion; (2) with 1 degrees 53' disparity, both conditions produced perceived depth and perceived motion; and (3) when the expectation to see depth was removed, the no-head-movement condition with the square-wave gradient produced no perceived depth, only motion. We suggest that monocular stereopsis with head movement can be achieved without perception of motion but monocular stereopsis without head movement requires perception of motion.  相似文献

55 English-speaking institutionalized adolescents (37 boys and 18 girls between ages of 14 and 19 yr.) were given questionnaires measuring perceived parental inconsistency and different components of emotional development. Canonical correlation analysis indicated that a significant proportion (51%) of the variation in emotional adjustment was accounted for by parental inconsistency. It is suggested that the efficiency of using parents as agents of change for their behaviour-disordered children can be enhanced by including theory on parenteral inconsistency in program content.  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

Learning to be possessed has been described elsewhere by the writer as a form of pathogenic relating begun when children are taught by adults that they will receive a lesser penalty for misbehavior if they can show they were not responsible, such as if it were caused by an evil agent or the Devil. It was suggested that learning to be possessed can be an underlying cause of psychopathology, the delusion of persecution in particular. Two short stories by the distinguished American writer Edgar Allan Poe are examined to develop the formulation of learning to be possessed, especially when it has passed to a delusion of persecution. Two propositions are offered: (1) Where it appears that a family member is murdered by a delusional assailant by accident, it is not an accident; and (2) the delusion of persecution entails a memory loss so that the murderer not only can claim lack of personal responsibility for the act, but also spares himself the guilt of having broken a fundamental taboo. Further comparison is made between learning to be possessed as a cause of delusion, and the psychoanalytic theory in which the defense mechanism of projection is central. In the latter theory, interpretation of the delusion is critical; whereas in the former, interpretation is counterproductive because it merely reinforces the delusion.Probably a note of appreciation is due the writer's daughter Cary, who at age 14 is an expert at badgering her father for help with homework assignments. For several weeks the writer was alternatively pestered and cajoled to help Cary with her Poe Project for high school English which required an essay analyzing the work of a great American writer denigrated by the author as weird by his recollection formed decades earlier. Cary's persistence required the author to consider Poe anew, to recognize his unwarranted earlier prejudice, and to recognize that Poe offered him a gift of understanding regarding a topic about which the author had been thinking for several years, namely that form of pathogenic relating named learning to be possessed.  相似文献
