Phonological sensitivity is an important causal variable in reading acquisition; however, there is controversy concerning its nature. One view holds that sensitivity to various linguistic units reflects independent abilities, whereas another holds sensitivity to these units reflects one ability. We examined relations among sensitivity to words, syllables, rhymes, and phonemes in 149 older preschool children (4- and 5-year-olds) and 109 younger preschool children (2- and 3-year-olds) who completed eight measures of phonological sensitivity and measures of print knowledge. Confirmatory factor analyses of all combinations of word, syllable, rhyme, and phoneme factors found that a one-factor model best explained the data from both groups of children (CFIs >.98). Only variance common to all phonological sensitivity skills was related to print knowledge and rudimentary decoding. Findings support a developmental conceptualization of phonological sensitivity.  相似文献

Fifty students responded to a semantic differential questionnaire designed to test the meaning of sexually symbolic concepts. Two measures were used: first, the mean potency score, and, second, the mean score on the masculine-feminine (M - F) subscale. It was found that a number of discrepancies occurred between (a) mean potency and mean M - F scores; (b) mean potency score and predictions based on psychoanalytic theory; and (c) mean M - F scores and predictions based on psychoanalytic theory. The results were interpreted within a learning theory framework in accord with Staats' (1968) theoretical formulation.  相似文献

The usefulness and efficacy of group psychotherapy with a variety of adolescent problems has been well documented. Far less has been reported with respect to group treatment approaches for youthful depressives, however. Currently available treatments lack specificity, making replication difficult. Additionally, they often focus on a narrow range of deficit areas rather than addressing the multifaceted range of dysfunction characteristic of depression in adolescents. This paper critically reviews the available literature on group treatments with depressed adolescents, explores some of the shortcomings inherent in these reports, and suggests alternatives for future group protocols. It is proposed that subsequent interventions be manualized and that they target affective, behavioral, and cognitive aspects of adolescent depression. Such an approach would be more amenable to scientific investigation, replication, and comparison with alternative approaches.  相似文献

Previous research has described the significant role that social interaction plays in both the acquisition and use of speech by parrots. The current study analyzed the speech of one home-raised African Grey parrot (Psittacus erithacus erithacus) across three different social contexts: owner interacting with parrot in the same room, owner and parrot interacting out of view in adjacent rooms, and parrot home alone. The purpose was to determine the extent to which the subject’s speech reflected an understanding of the contextual substitutability (e.g., the word street can be substituted in context for the word road) of the vocalizations that comprised the units in her repertoire (i.e., global co-occurrence of repertoire units; Burgess in Behav Res Methods Instrum Comput 30:188–198, 1998; Lund and Burgess in Behav Res Methods Instrum Comput 28:203–208, 1996). This was accomplished via the human language model hyperspace analog to language (HAL). HAL is contextually driven and bootstraps language “rules” from input without human intervention. Because HAL does not require human tutelage, it provided an objective measure to empirically examine the parrot’s vocalizations. Results indicated that the subject’s vocalization patterns did contain global co-occurrence. The presence of this quality in this nonhuman’s speech may be strongly indicative of higher-order cognitive skills.  相似文献

Abstract

In assessing the quality of life of patients with cancer. :in important. though largely ignored. variable is self-esteem. The development of an instrument to measure self-esteem, using visual analogue scales, is described. This instrument was administered to 170 patients with newly diagnosed early breast cancer. Hodgkin's disease and non-Hodgkin's lymphoma three months and one year alter diagnosis. The instrument was acceptable to patients; internal consistency and test-retest reliability data are reported. Self-esteem scores were inversely correlated with depression and trait anxiety scores, and positively correlated with internal locus of control. Self-esteem was not significantly affected by tumour grade or stage. or by the extent to which patients felt disabled by the symptoms and side effects of their disease and treatment. The implications of these findings are discussed.  相似文献

The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.  相似文献

This paper aims to make three contributions to decision theory. First there is the hope that it will help to re-establish the legitimacy of the problem, pace various recent analyses provided by Maitzen and Wilson, Slezak and Priest. Second, after pointing out that analyses of the problem have generally relied upon evidence that is conditional on the taking of one particular option, this paper argues that certain assumptions implicit in those analyses are subtly flawed. As a third contribution, the piece aims to draw attention to an important similarity between Newcomb’s problem and the toxin puzzle. In short, both problems illustrate the fact that you can have a reason to intend to φ without having a reason to actually φ.  相似文献

Showups (a one-person identification) were compared to both simultaneous and sequential lineups that varied in lineup fairness and the position of the suspect in the lineup. We reanalyzed data from a study by Gronlund, Carlson, Dailey, and Goodsell (2009), which included simultaneous and sequential lineups, and using the same stimuli and procedures, collected new data using showup identifications. Performance was compared using ROC analysis, which is superior to traditional measures such as correct and false identification rates, and probative value measures. ROC analysis showed that simultaneous lineups consistently produced more accurate identification evidence than showups, but sequential lineups were sometimes no more accurate than showups, and were never more accurate than simultaneous lineups. These results supported prior suppositions regarding the suggestiveness of showups, revealed a misconception about the superiority of sequential lineups, and demonstrated why eyewitness identification procedures need to be evaluated using ROC analyses.  相似文献
