Word reading partly depends on the activation of sublexical letter clusters. Previous research has studied which types of letter clusters have psychological saliency, but less is known about cognitive mechanisms of letter string parsing. Here, we take advantage of the high degree of context-dependency of the Russian orthography to examine whether consonant–vowel (CV) clusters are treated as units in two stages of sublexical processing. In two experiments using a nonword reading task, we use two orthogonal manipulations: (a) insertion of a visual disruptor (#) to assess whether CV clusters are kept intact during the early visual parsing stage, and (b) presence of context-dependent grapheme–phoneme correspondences (GPCs; e.g., л[а] → /l/; л[я] → /lj/), to assess whether CV clusters remain intact or are split during the print-to-speech conversion stage. The results suggest that although CV clusters are initially processed as perceptual units in the early visual parsing stage, letters and not CV clusters drive print-to-speech conversion.  相似文献

In five studies we show that the introduction of the Euro influences price estimations and the perception of salaries among people in Germany. People confronted with wages given in Euros compared to the German Mark (DM) showed a reduced willingness to face long distances to get to work when accepting a job offer. When asked to price various consumer goods appropriately, they estimated higher prices if they used the ‘Euro’ currency compared to price estimations made in DM. This phenomenon only occurred with regard to the Euro, but not in comparison with other currencies (cf. the British Pound and Austrian Schilling). The differing price estimations between the Euro and the German Mark were not influenced by participants' attitude towards the Euro. Moreover, it turned out that they depended on how the judgement context was framed. Only if participants expected to make price estimations for shops in their home country, Germany, did the familiar nominal DM figures serve as an anchor heightening the estimated prices in Euro. The same effect disappeared if participants were instructed to make their price estimations for shops in a foreign country (Ireland). Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Reflecting Teams (RTs) are an internationally recognized clinical consultation methodology, first developed by Tom Andersen in 1985. Over the last three decades, family therapists around the world have used RTs to enhance treatment. However, this innovation to family therapy practice is not well‐standardized nor evaluated. The pilot study described in this article is an attempt to expand on the previous studies on RTs, and quantitatively examines RTs conducted with family therapy participants at a university medical center psychiatric institute. Preliminary analyses indicate that after participating in a single RT, family members may feel more hopeful, believe they can better support each other in times of stress, have more confidence in working together, and resolve conflicts. Additionally, the analyses suggest that family members may feel better understood and have more ideas about how to have a conversation with their family members, even though, after the RT, they may not view their family differently. These preliminary results suggest that further studies should explore the influence of RTs on family functioning.  相似文献

Few data are available on alcohol experiences among elementary school children, although early onset and trying of alcohol use is known to be a risk factor for adolescent alcohol abuse. Until now, research leaves open the question on which factors encourage early trying behavior. In a cross-sectional study design, a written survey was conducted in 49 randomly selected elementary schools in Germany. The survey was carried out among 3rd and 4th graders with a median age of 9 years during class time in the school year 2010/2011. 1806 questionnaires were included in the study. The risk behavior of having tried alcohol was analyzed. A total of 37.7% (n = 681) of all children reported to have already tried alcohol. While grade and age had no significant influence in the final multivariate model, the gender effect stayed relevant (Male: aOR 1.2, 95%-CI 1.0–1.5), as did the question of whether the child liked going to school (No: aOR 1.4, 95%-CI 1.1–1.7), a lack of parental monitoring (aOR 1.5, 95%-CI 1.1–2.1), consistent parenting (Sometimes/never: aOR 1.5, 95%-CI 1.1–1.9), a regularly provided break-time snack (No: aOR 2.2, 95%-CI 1.3–3.8), as well as parents’ drinking (Yes: aOR 2.0, 95%-CI 1.6–2.6) and drinking among peers (Yes: aOR 8.5, 95%-CI 6.2–11.6). Our study shows that alcohol experiences can be highly prevalent among 3rd and 4th grade elementary school children in Germany. Our findings suggest that especially those variables which may be controlled by the parents are strongly associated with children’s alcohol experiences suggesting a starting point for preventative intervention measures. The results also indicate the need for innovative gender-sensitive approaches in the living environment of elementary school children.  相似文献

The study investigated whether the P600/SPS component is sensitive to the richness of semantic content in sentences. ERPs were recorded while 30 native Swedish speakers read sentences, of which half were syntactically correct and half contained a syntactic violation. Both kinds of sentences came in one of three types of descending semantic completeness: semantically coherent sentences, sentences which were incoherent due to violations of selectional restrictions, or sentences of pseudo words, hence void of lexical content. In the semantically coherent sentences a P600/SPS was found for the syntactic violation. A less salient positivity was found for the violation in the semantically incoherent sentences. No P600/SPS was found for the syntactic violation in the pseudo word sentences and no LAN component in any sentence type. The results are interpreted as supporting the hypothesis that the P600/SPS component reflects a semantically based reanalysis process.  相似文献

A potential mechanism that can explain preterm children's heightened risk for the development of later cognitive and behavioral problems is attention. Attention is the ability of an infant or child to orient to, to shift between and to maintain focus on events, objects, tasks, and problems in the external world, processes which are all dependent on the functioning of attentional networks in the brain. The aim of this paper is to provide a review of the literature on attention development in children born preterm during the first 4 years of life. First, research examining the differences between preterm and full-term children indicates that early attention development in infants born preterm is less optimal and that these differences increase when infants grow into toddlers. Second, studies investigating individual differences within preterm populations reveal the influence of both biological factors and environmental factors. Third, individual differences in early orienting and sustained attention have been shown to be predictive of later attentional, cognitive and behavioral functioning in children born preterm. The importance of long-term follow-up studies, with a focus on individual developmental trajectories in orienting, sustained and executive attention, is emphasized.  相似文献

The main purpose of this article is to analyse integration in Compulsory Secondary School and the variables that teachers perceive as its indicators. More specifically, we wished to determine teachers' experience, their perceptions of integration students' achievement, participation, acceptance and involvement, and their appraisal of various measures in order to improve integration. Various preferred means of schooling and teachers' perception of the functioning of integration are analysed with a Likert-scaled questionnaire made up of 114 items. The sample comprised 242 secondary education teachers. The results show that the most poorly integrated group of students had behavioural problems and that a significant percentage of the teachers would prefer not to have these students in their classrooms. According to the teachers, integration does not work effectively with some groups of students, mainly due to the lack of resources and adequate strategies.  相似文献
