Achieving a preventive attitude is the first step in eliminating cancer risk behaviours. This cross-sectional study evaluated the attitude towards the European Code against Cancer, in 3,031 relatives of cancer patients. The study looked for keys to improve attitude by means of educational interventions. Attitude was evaluated using a questionnaire with 63 items and a Likert's scale. Measured from -2 to +2 , the mean score was 0.905 [0.894 - 0.971]. Five per cent had a mean score under 0.38 and another 5% over 1.46. A multivariate analysis found that age, sex and level of education were significantly associated with attitude: young men with a low cultural level were those with the lowest preventive attitude. The family history of cancer was not associated with attitude. Educational interventions should modify the perceived advantages of smoking and drinking, and the disadvantages related to preventive diet and sun and workplace protection. 相似文献

Many studies have shown that IQs have been increasing over the last half century. These increases have come to be known as "the Flynn effect". The "Flynn effect" represents a difference on ability-level between groups of the same age but different cohort. The ability-level differentiation hypothesis represents a difference on the relevance of cognitive factors between groups of high and low ability. Hence, it should be possible to imitate the ability-level differentiation effect by comparing groups of the same age but different cohort. The indifferentiation hypothesis represents no differences on the relevance of cognitive abilities in all age groups within the same cohort. The aim of the present study is to test the relationships between these phenomena. For this purpose we analyzed the American standardisation samples of the WISC, WISC-R and WISC-III. Results support the link between the Flynn effect and the differentiation hypothesis. Also, reported evidence replicate previous findings supporting the indifferentiation hypothesis. Implications for the assessment of the intelligence are discussed. 相似文献

A masked priming lexical decision experiment was conducted to examine whether or not assignment of letter position in a word
can be influenced by lexeme boundaries. The experiment was run in Basque, which is a strongly agglutinating language with
a high proportion of inflected and compound words. Nonword primes were created by transposing two nonadjacent letters that
crossed or did not cross morphological boundaries. Specifically, we compared morphologically complex prime-target pairs (e.g.,arbigide-ARGIBIDE) with orthographic controls (e.g.,arkipide-ARGIBIDE; note that ARGIBIDE is a compound of ARGI + BIDE) and noncompound pairs (e.g.,ortakila-ORKATILA) with orthographic controls (e.g.,orbahila-ORKATILA). Results showed that transposed-letter effects were virtually the same for compound and noncompound words, both
when the orthographic control condition was used as a baseline and when the identity condition was used as a baseline. Thus,
transposed-letter similarity effects seem to be orthographic in nature. We examine the implications of these results for the
models of visual word recognition. 相似文献

Two masked priming experiments were conducted to examine phonological priming of bisyllabic words in French, and in particular, whether it operates sequentially or in parallel. Bisyllabic target words were primed by pseudowords that shared either the first or the second phonological syllable of the target. Overlap of the first syllable only-not the second-produced facilitation in both the lexical decision and the naming tasks. These findings suggest that, for polysyllabic words, phonological codes are computed sequentially during silent reading and reading aloud. 相似文献

Using survey methodology, this exploratory study examined the attitudinal and perceptual dimensions of body image among 1,272 eighth- and ninth-grade males and females from higher and lower socioeconomic backgrounds in Buenos Aires, Argentina (n = 195), Guatemala City, Guatemala (n = 212), Havana, Cuba (n = 213), Lima, Peru (n = 218), Panama City, Panama (n = 195), and Santiago, Chile (n = 239). The two dimensions of body image were assessed by showing the participants nine male and nine female silhouettes depicting body sizes ranging from extremely thin (#1) to extremely obese (#9). Approximately 50% of the male and female adolescents chose silhouette #3 as best depicting the attractive male body. Silhouette #2 was chosen by 45% of the females as best depicting feminine attractiveness, while 45% of the males chose silhouette #3. When identifying the silhouette that best depicted the healthy male body, 26% of the participants chose silhouette #2, 41% chose #3, and 19% chose #4. Silhouette #2 was selected by 33% of the adolescents as best depicting the healthy female body, 38% chose #3, and 14% chose #4. In all cities, the effect of body mass index (BMI) on body satisfaction was highly significant (p < 0.001). Almost 40% of the middle weight adolescents indicated a preference to be thinner, even though 72% of the males and 84% of the females in this subgroup already perceived themselves as thin. Similarly, 89% of the heavier weight participants indicated a preference to be thinner, even though only 10% of the males and 2% of the females in this subgroup perceived themselves as heavy. In five of the six cities, a significantly higher (p < 0.05) percentage of females than males desired to be thinner, the exception being Havana, where the distribution of desired change in body size was almost identical for males and females. Findings suggest a need for culturally sensitive, age- and gender-specific preventive interventions focusing on the importance of achieving a healthy weight during adolescence to promote body size acceptance among adolescents who are at a healthy weight. 相似文献

An eye-movement monitoring experiment was carried out to examine the effects of the difficulty of the problem (simple versus complex problems) and the type of figure (figure 1 or figure 4) on the time course of processing categorical syllogisms. The results showed that the course of influence for these two factors is different. We found early processing effects for the figure but not for the difficulty of the syllogism and later processing effects for both the figure and the difficulty. These results lend support to the Model Theory (Johnson-Laird, P. N., Byrne, R. M. J. (1991). Deduction. Hillsdale, New Jersey: LEA.) as opposed to other theories of reasoning (Chater, N., Oaksford, M. (1999). The probability heuristics model of syllogistic reasoning. Cognitive Psychology, 38, 191-258; Rips, L. J. (1994). The psychology of proof. Cambridge, MA: MIT Press; Rips, L. J. (1994). The psychology of proof. Cambridge, MA: MIT Press). 相似文献

Standard models of practical rationality face a puzzle that has gone unnoticed: given a modest assumption about the nature
of deliberation, we are apparently frequently briefly irrational. I explain the problem, consider what is wrong with several
possible solutions, and propose an account that does not generate the objectionable result. 相似文献

Revisionism in the theory of moral responsibility is the idea that some aspect of responsibility practices, attitudes, or concept is in need of revision. While the increased frequency of revisionist language in the literature on free will and moral responsibility is striking, what discussion there has been of revisionism about responsibility and free will tends to be critical. In this paper, I argue that at least one species of revisionism, moderate revisionism, is considerably more sophisticated and defensible than critics have realized. I go on to argue for the advantages of moderate revisionist theories over standard compatibilist and incompatibilist theories. 相似文献

Evidence for an early involvement of phonology in word identification usually relies on the comparison between a target word preceded by a homophonic prime and an orthographic control (rait-RATE vs. raut-RATE). This comparison rests on the assumption that the two control primes are equally orthographically similar to the target. Here, we tested for phonological effects with a masked priming paradigm in which orthographic similarity between priming conditions was perfectly controlled at the letter level and in which identification of the prime was virtually at chance for both stimulus onset asynchronies (SOAs) (66 and 50 msec). In the key prime-target pairs, each prime differed from the target by one vowel letter, but one changed the sound of the initial c, and the other did not (cinal-CANAL vs. conal-CANAL). In the control prime-target pairs, the primes had the identical vowel manipulation, but neither changed the initial consonant sound (pinel-PANEL vs. ponel-PANEL). For both high- and low-frequency words, lexical decision responses to the target were slower when the prime changed the sound of the c than when it did not, whereas there was no difference for the controls at both SOAs. However, this phonological effect was small and was not significant when the SOA was 50 msec. The pattern of data is consistent with an early phonological coding of primes that occurs just a little later than orthographic coding. 相似文献

Four experiments explored the interrelations between working memory, attention, and eye movements. Observers had to identify a tilted line amongst vertical distractors. Each line was surrounded by a colored shape that could be precued by a matching item held in memory. Relative to a neutral baseline, in which no shapes matched the memory item, search was more efficient when the memory cue matched the shape containing the target, and it was less efficient when the cued stimulus contained a distractor. Cuing affected the shortest reaction times and the first saccade in search. The effect occurred even when the memory cue was always invalid but not when the cue did not have to be held in memory. There was also no evidence for priming effects between consecutive trials. The results suggest that there can be early, involuntary top-down directing of attention to a stimulus matching the contents of working memory. 相似文献
