This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to synaesthetes experiencing taste and to control participants lacking any synaesthetic experience. This suggests that the presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Number forms are equally common in men and women, unlike previous reports of synaesthesia that have suggested a strong female bias. Individuals who possess a number form are also likely to possess visuo-spatial forms for other ordinal sequences (e.g. days, months, letters) which suggests that it is the ordinal nature of numbers rather than numerical quantity that gives rise to this particular mode of representation. Finally, we also describe some consequences of number forms for performance in a number comparison task. 相似文献

The relationship between defense mechanisms and symptoms was assessed in a group of 196 psychiatrically hospitalized adolescents. Defense mechanisms were measured through the use of the Defense Mechanisms inventory (DMI); symptoms and problem behaviors were measured with the Youth Self-Report. Univariate and multivariate analyses indicated that externalizing symptoms are associated with defenses that locate the conflict outside of the self, whereas internalizing symptoms are associated with defenses that locate the conflict within the self. In contrast to previous reports, no gender differences, were found in defense preference, though gender differences were found in the relation of defenses to symptoms. The findings are consistent with clinical theory of defense processes and support the distinction between internalizing/externalizing behaviors and personality dimensions for both symptoms and defenses. The study supports the validity of the adolescent form of the DML. 相似文献

In recent years three books have appeared which contribute greatly to our knowledge of Pavlov’s life and work, and of the development of the laboratory in Leningrad which bears his name and his intellectual imprint. These works are (1) A volume of brief, highly personal comments on I. P. Pavlov (Kreps, 1967); (2) A collection of short biographies, pictures, and selective bibliographies of individuals who had worked with Pavlov (Kvasov and Fedotova-Grot, 1967); and (3) An outline of the history of the I. P. Pavlov Institute of Physiology which grew from a most unprepossessing laboratory, taken over by I. P. Pavlov in 1907, into a giant institution with a staff currently exceeding 1,000 (Lange, 1968). 相似文献

Background: In the DSM-5, the diagnosis of hypochondriasis was replaced by two new diagnositic entities: somatic symptom disorder (SSD) and illness anxiety disorder (IAD). Both diagnoses share high health anxiety as a common criterion, but additonal somatic symptoms are only required for SSD but not IAD. Design: Our aim was to provide empirical evidence for the validity of these new diagnoses using data from a case–control study of highly health-anxious (n = 96), depressed (n = 52), and healthy (n = 52) individuals. Results: The individuals originally diagnosed as DSM-IV hypochondriasis predominantly met criteria for SSD (74%) and rarely for IAD (26%). Individuals with SSD were more impaired, had more often comorbid panic and generalized anxiety disorders, and had more medical consultations as those with IAD. Yet, no significant differences were found between SSD and IAD with regard to levels of health anxiety, other hypochondriacial characteristics, illness behavior, somatic symptom attributions, and physical concerns, whereas both groups differed significantly from clinical and healthy controls in all of these variables. Conclusion: These results do not support the proposed splitting of health anxiety/hypochondriasis into two diagnoses. Further validation studies with larger samples and additional control groups are warranted to prove the validity of the new diagnoses. 相似文献

This study investigated the effects of environmental enrichment on the cognitive performance of female conventional farm (growing) pigs in a spatial holeboard task. Ten pairs of littermates matched for weight were used. From each litter, one piglet was randomly assigned to a barren environment; the other was assigned to an enriched environment from 4 weeks of age. The enriched environment was double the size of the barren environment, had a floor covered with straw, a rooting area filled with peat, and one of the four different enrichment toys which were exchanged daily. Starting at 11 weeks of age, all pigs were tested in a spatial holeboard discrimination task in which 4 out of 16 holes were baited. Furthermore, basal salivary cortisol levels of all pigs were determined after the end of all testing. All pigs were able to acquire the pattern of baited holes (acquisition phase, 40 trials) and the diagonally mirrored pattern (reversal phase, 20 trials). During the acquisition phase, the reference memory performance of the enriched-housed pigs was better than that of their barren-housed littermates, i.e. they reduced visits to the unbaited set of holes. During the reversal phase, enriched-housed pigs had a better general working memory performance than the barren-housed pigs as indicated by reduced revisits to holes already visited during a trial, irrespective of whether they were of the baited or the unbaited set. The enriched-housed pigs also searched for the hidden bait faster during both phases. The environments did not affect basal salivary cortisol levels. In conclusion, environmental enrichment slightly improved the cognitive performance of pigs in a spatial learning task. We hypothesise that the long period of habituation to and testing in the holeboard acted as enrichment that partially reduced the effects of barren housing. 相似文献
