Treiman (1983) and others have argued that spoken syllables are best characterized not as linear strings of phonemes, but as hierarchically organized units consisting of an onset (initial consonant or consonant cluster) and a rime (the vowel and any following consonants) and that the rime is further divided into a peak or nucleus (the vowel) and a coda (the final consonants). It has also been argued that the sonority (or vowel-likeness) of the consonant closest to the peak, which is a function of its phonetic class, may have an effect on the strength of boundaries determined by the hierarchical division of the syllable (e.g., Treiman, 1984). We examined the evidence for syllable-internal structure and for sonority in two experiments that employed visually presented stimuli and lexical decision, naming, and reading tasks. Our results provide support for the breakdown of the rime into a peak and a coda and for an effect of the sonority of the postvocalic consonant on that break. This pattern occurred only in our lexical decision tasks, so the effect is assumed to be postlexical. We did not find an effect of the onset-rime boundary, perhaps because of an unanticipated effect of word frequency. Our results are discussed in terms of phonological coding in short-term memory. 相似文献

Several authors have suggested that perfectionism is associated with irrational thinking. The purpose of the present research was to test the hypothesis that various dimensions of perfectionism are related significantly to core irrational beliefs. In Study 1, 102 subjects completed the Multidimensional Perfectionism Scale (MPS) and the Irrational Beliefs Test (IBT). The MPS provides assessments of self-oriented, other-oriented, and socially prescribed perfectionism. Analyses revealed that self-oriented perfectionism was correlated positively with the IBT high self-expectations and perfect solutions subscales. Socially prescribed perfectionism was correlated significantly with a variety of irrational beliefs including high self-expectations, demand for social approval, dependency, blame proneness, and anxious overconcern. Other-oriented perfectionism was correlated with few irrational beliefs. In Study 2, 130 subjects completed the MPS and the Survey of Personal Beliefs, a new measure of core irrational beliefs. Analyses confirmed that all three perfectionism dimensions were associated with core irrational beliefs. It is concluded that the results constitute general support for the hypothesis that cognitive aspects are important in both personal and social components of perfectionism and that perfectionists are characterized by increased levels of irrational beliefs that may contribute to maladjustment. The findings are discussed in terms of the associations among perfectionism, irrational beliefs, and maladjustment.Gordon L.

Mental arithmetic abilities were studied among unschooled African adults and American college students. A set of problems tested the use of the four basic arithmetic operations. Performance was analyzed for: strategies, implicit arithmetic principles, and explicit explanations of the principles. Both groups showed accurate mental arithmetic strategies related to the base ten structure of their native counting systems. The American students' mental strategies additionally made use of algorithms based on written place values. Several principles were implicit in the calculation strategies of both groups, and both used these principles to short-cut calculations. Though the African subjects did not, the American subjects did describe these abstract principles in explicit common language or algebraic expressions. Relationships between schooling and cognition are discussed. 相似文献

Duration discrimination of the last of a series of four clicks was investigated. Examination of psychophysical functions from eight subjects revealed evidence for a Weber’s law model relating discrimination to base interclick interval. Also, the point of subjective equality was seen to change reliably as a function of base rate. 相似文献

The present investigation was conducted to determine whether subjects could use categorical codes based on semantic memory information (gender of names) to make rapid decisions about the order of names in a linear series. Subjects were taught linear order problems in which 12 names (six male and six female) were either randomly ordered or blocked by sex. The results support a dual-process model which proposes that subjects use both categorical information (discrete linguistic codes) and serial position information when asked to make mental comparisons of arbitrarily ordered items. Furthermore, the data indicate that both the ordinal distance between the terms in the test pair (step size) and the serial position of the test terms in the linear order affect the reaction time to a particular test comparison. 相似文献

Combined treatment approaches, co-therapy and family work are three concepts which are under much discussion in psychiatry. This paper describes the systematic use of an integrated treatment approach used by co-therapists working with families in which a child was the referred patient. The rationale behind this approach together with its advantages and disadvantages are discussed. The authors conclude that the approach is sufficiently promising to merit formal evaluation. 相似文献

McCauley, Stitt, Woods and Lipton's finding that groups were more conservative than individuals when betting at a race track has been criticized on statistical and methodological grounds. The present study which does not suffer the shortcomings for which McCauley et al. were legitimately criticized does, nonetheless, sustain their general results and conclusions. Groups were significantly more cautious than individuals when wagering $2.00 on a horse race. 相似文献
