English-speaking children typically avoid using regular plurals in novel grammatical deverbal compounds as in rat eater but allow irregular plurals as in mice eater (Gordon, 1985). To explain these data, it has been argued that Kiparsky’s (1983) level-ordering model constrains the production of morphologically complex words, including those with which children have had little to no experience. If level-ordering can be supported, children should avoid regular plurals in their ungrammatical deverbal compounds like a breaker-bottle. Seventy-two English-speaking children were included in the present study, 36 from Britain and 36 from Canada. The results showed that 50% of the children who produced ungrammatical compounds included regular plurals in the compounds they produced. Conversely, none of the children who produced grammatical compounds included regular plurals. These results indicate that level-ordering does not constrain children’s production of ungrammatical compounds. These results raise the possibility that level-ordering may not be a valid constraint of children’s compounding in general.  相似文献

This paper analyzes the impact of Italian immigration policies on migrants’ lives. Policies and changes in policies can affect migrants’ capabilities to stabilize themselves in the host country, in terms of legal residence and secure labor conditions, as well as their chances of becoming part of the host society. We argue that, together with border controls, these are crucial ways through which immigration policies may have the postulated effects on the lives of migrants. We use data from 59 in-depth interviews conducted with first-generation Moroccan and Egyptian migrants living in two Italian cities, Turin and Rome, in the period 2011–2013. The results show that Italian immigration policies do not successfully control migration inflow, but effectively hinder the stability of migrants’ legal status and the status transition from temporary residence to permanent residence and subsequent Italian citizenship. In this way, Italian immigration policies largely affect migrants’ capabilities to be part of the host country; this gets in the way of integration, social cohesion, and future migration projects.  相似文献

People with Williams syndrome are characterized by linguistic abilities that are higher than their level of intelligence. There is controversy concerning their reading level because there are few studies. The aim of this work was to test reading abilities in a group of school-age children with Williams syndrome. Their performance was contrasted with a control group of the same mental age. Three kinds of tasks were used: word and pseudoword reading, phonological awareness, and naming speed. Results show that the Williams syndrome children performed similarly to control children in reading accuracy but were slower in reading words and pseudowords. They were also slower in the naming speed tasks. These results suggest that Williams syndrome children do not have difficulties in developing grapheme-phoneme decoding but do present some difficulties in developing lexical reading.  相似文献

According to the Fr?hlich effect, observers perceive the initial position of a fast moving stimulus displaced in the direction of motion. On the basis of Kirschfeld and Kammer's as well as Fr?hlich's original assumption that metacontrast plays an important role in the emergence of the phenomenon, we predicted different amounts of misperception for stimulus enlargement compared to stimulus reduction. These basic predictions were confirmed in Experiment 1. In Experiment 2, we investigated whether an overestimation-bias might account for these results. But the overestimation of non-changing stimuli was too small to adequately explain the dissociation. In Experiment 3, we predicted and found different effects of the factor stimulus lightness on misperception in the enlargement and reduction condition. In Experiment 4, we showed that misperception in the enlargement condition is reduced when frames are used instead of filled stimuli, as in the earlier experiments. Results are discussed with respect to the original Fr?hlich effect.  相似文献

Cognitive neuroscientists have anticipated the union of neural and behavioral science with ethics (Gazzaniga 2005). The identification of an ethical rule--the dictum that we should treat others in the manner in which we would like to be treated--apparently widespread among human societies suggests a dependence on fundamental human brain mechanisms. Now, studies of neural and molecular mechanisms that underlie the feeling of fear suggest how this form of ethical behavior is produced. Counterintuitively, a new theory presented here states that it is actually a loss of social information that leads to sharing others' fears with our own, thus allowing us to treat others as we would like to be treated. Adding to that hypothetical mechanism is the well-studied predilection toward affiliative behaviors. Thus, even as Chomsky hypothesizes that humans are predisposed to utter grammatical sentences, we propose that humans are 'wired for reciprocity'. However, these two neural forces supporting ethical behavior do not explain individual or collective violence. At any given moment, the ability to produce behavior that obeys this ethical rule is proposed to depend on a balance between mechanisms for prosocial and antisocial behaviors. That balance results not only from genetic influences on temperament but also from environmental effects particularly during critical neonatal and pubertal periods.  相似文献

This article presents a study whose objective was to identify certain personal and institutional variables that are associated with academic achievement among Spanish, secondary school students, and to analyze their influence on the progress of those students over the course of that stage of their education. In order to do this, a longitudinal, multi-level study was conducted in which a total of 965 students and 27 different schools were evaluated in Language, Math and Social Science at three different times (beginning, middle and end of the period). The results show progress in all the schools and in all areas. As for the personal, student variables, the longitudinal, HLM analyses confirmed the importance of sex and sociocultural background and, distinguishing it from other studies, also the predictive capacity of meta-cognitive abilities and learning strategies on success in school. On the institutional level, the school climate and teachers' expectations of their students were the most relevant of the variables studied. The size of the school, the percentage of students who repeat grades, and the leadership of the administration also explained a portion of the variance in some areas.  相似文献

The attachment styles and parental bonding of 72 patients (M age= 45.3 yr., SD=13.5) suffering from Gastroesophageal Reflux Disease were compared with those of 105 healthy subjects (M age =44.9 yr., SD = 5.8). A clinical interview and two questionnaires, the Attachment Style Questionnaire and the Parental Bonding Instrument, showed that the scores on the ASQ Confidence subscale were significantly lower in the clinical group. Similar results were obtained for the Discomfort with Closeness subscale in the subsample with Pure Gastroesophageal Reflux Disease. The results indicate Insecure Attachment in the clinical sample. The results obtained from the Parental Bonding Instrument indicate that scores on the Protection Mother scale were significantly higher in the clinical subjects, suggesting a Low Care-High Protection combination (Affectiveless Control), at least for patients with pure Gastroesophageal Reflux Disease. These characteristics can be considered important factors in the tendency to somatization. The symptoms may have a paradoxically normalising function while the patient shows an emotional detachment towards intimate relationships. The illness appears to act as a bond through which the relationship with the caregivers is maintained.  相似文献

Is there a specific neurocognitive system underlying the subjective sense of having a unitary continuous self across time? If so, it should be possible to isolate functions involved in the sense of self from those supporting mental activities that the self is currently engaged in. We report a study of real-time noninvasive recordings of the brain's electrical activity (event-related potentials, ERPs). We found a common neural signature that is associated with self-referential processing regardless of whether subjects are retrieving general knowledge (noetic awareness) or reexperiencing past episodes (autonoetic awareness). These ERP data are consistent with models of autobiographical memory that postulate a single locus of control over explicit memory for various kinds of self-related information. The temporal properties and scalp distribution of this novel self-reference ERP effect also suggest that it may be a neurophysiological correlate of self-related activation in medial prefrontal and parietal neocortical circuits identified in functional magnetic resonance imaging experiments.  相似文献

Controversies exist regarding the impact of psychological stress on the functioning of the immune system in humans. The aim of the present study, therefore, was to evaluate whether the condition of a pre-exam stress may or not modify resting lymphocyte subsets, as well as blood pressure and heart rate. About 22 medical residents of both sexes not suffering from any medical or psychiatric disorder were included in the study. Anxiety levels were measured by means of the Hamilton rating scale for anxiety (HRSA) and anxiety traits by means of the panic-agoraphobic spectrum self-report (PAS-SR) version and the obsessive-compulsive spectrum self-report (OBS-SR) version. The results showed that systolic blood pressure and heart rate increased significantly just before sitting an examination (t(1)) in all subjects, as compared with a calm situation (t(2)), in parallel with the increase in the HRSA total score, while no significant difference was observed in lymphocyte subsets at the two assessment times. However, men had a higher number of CD4+ cells than women at t(1) and t(2), while women showed a higher heart rate at t(1). In addition, significant correlations between CD4+ lymphocyte count and heart rate at t(1) or HRSA at t(2) were detected. These findings indicate that the acute stress determined by sitting for examination provokes changes in autonomic nervous system parameters, such as blood pressure and heart rate, as well as in the subjective feeling of anxiety, as shown by the increased HRSA total scores, which were not paralleled by modifications of lymphocyte subsets. However, individual differences, related to both sex and personality traits yet to be identified, seem to have an impact in shaping the stress response.  相似文献
