Posttraumatic stress disorder (PTSD) is an anxiety disorder in which an individual re-experiences a traumatic event, avoids situations related to it, and shows excessive arousal. The disorder appears after experiencing a life-threatening event, such as a war or a natural disaster. Thus, the validation of tests which assess the disorder after the earthquake on February 27, 2010, in Chile is crucial for its evaluation and subsequent intervention. The present study includes psychometric data for the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) on a sample of 509 survivors of the disaster. Values indicate good psychometric properties of the questionnaire. 相似文献

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology
in general. Instead of taking knowledge attributions as the primary use of the verb ‘to know’ that needs to be given an account
of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge
that is given here understands first-person knowledge claims as the primary use of the verb ‘to know’. This means that a cognitive
act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to
explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of
the problems in modern epistemology, such as the Gettier problem. 相似文献

Disambiguating Information and Memory Resources in Children’s Processing of Italian Relative Clauses
We investigated the role of number agreement on verb and of animacy in the comprehension of subject and object relative clauses
in 51 monolingual Italian-speaking children, mean age 9:33, tested through a self-paced listening experiment with a final comprehension question. A digit span test and a listening span test were also administered to examine the role of memory in comprehension. Subject relative clauses were easier to comprehend
than object relative clauses; animacy of the relative clause head improved comprehension of object relative clauses; memory,
as measured by the digit span test, modulates comprehension of object relative clauses, both with animate and inanimate heads,
as shown in response accuracy. Although all children process number agreement morphology on the verb, only some perform a
correct reanalysis, as shown by the accuracy measures. We argue that number agreement disambiguation is particularly taxing
for children, as it provides a negative symptom in the sense of Fodor and Inoue (J Psycholinguist Res 29(1):25–36, 2000) and reanalysis requires them to hold two dependencies in memory. 相似文献

In languages with flexible constituent order (so-called free word order languages), available orders are used to encode given/new distinctions; they therefore differ not only syntactically, but also in their
context requirements. In Experiment 1, using a self-paced reading task, we compared Russian S V IO DO (canonical), DO S V
IO and DO IO V S constructions in appropriate vs. inappropriate contexts (those that violated their context requirements).
The context factor was significant, while the syntax factor was not. The less pronounced context effect evidenced in previous
studies (e.g., Kaiser and Trueswell in Cognitioin 94:113–147, 2004) might be due to the use of shorter target sentences and less extensive contexts. We also demonstrated that the slow-down
starts at the first contextually inappropriate constituent, which shows that the information about context requirements is
taken into account immediately, but that it develops faster on preverbal subjects and postverbal indirect objects (occupying
their canonical positions) than on preverbal indirect objects (occupying a noncanonical position, or scrambled). In Experiment 2, these findings were replicated for IO S V DO and IO DO V S orders. S V IO DO orders with a continuation
were used to show that there is no additional effect of inappropriate context at the end of the sentence. 相似文献

The personality trait Openness/Intellect reflects the tendency to be imaginative, curious, perceptive, artistic, and intellectual - all characteristics that involve cognitive exploration. Little is known about the biological basis of Openness/Intellect, but the trait has been linked to cognitive functions of prefrontal cortex, and the neurotransmitter dopamine plays a key role in motivation to explore. The hypothesis that dopamine is involved in Openness/Intellect was supported by examining its association with two genes that are central components of the prefrontal dopaminergic system. In two demographically different samples (children: N = 608; adults: N = 214), variation in the dopamine D4 receptor gene (DRD4) and the catechol-O-methyltransferase gene (COMT) predicted Openness/Intellect, as main effects in the child sample and as a gene-gene interaction in adults. 相似文献

Speech remains intelligible despite the elimination of canonical acoustic correlates of phonemes from the spectrum. A portion of this perceptual flexibility can be attributed to modulation sensitivity in the auditory-to-phonetic projection, although signal-independent properties of lexical neighborhoods also affect intelligibility in utterances composed of words. Three tests were conducted to estimate the effects of exposure to natural and sine-wave samples of speech in this kind of perceptual versatility. First, sine-wave versions of the easy and hard word sets were created, modeled on the speech samples of a single talker. The performance difference in recognition of easy and hard words was used to index the perceptual reliance on signal-independent properties of lexical contrasts. Second, several kinds of exposure produced familiarity with an aspect of sine-wave speech: (a) sine-wave sentences modeled on the same talker; (b) sine-wave sentences modeled on a different talker, to create familiarity with a sine-wave carrier; and (c) natural sentences spoken by the same talker, to create familiarity with the idiolect expressed in the sine-wave words. Recognition performance with both easy and hard sine-wave words improved after exposure only to sine-wave sentences modeled on the same talker. Third, a control test showed that signal-independent uncertainty is a plausible cause of differences in recognition of easy and hard sine-wave words. The conditions of beneficial exposure reveal the specificity of attention underlying versatility in speech perception. 相似文献

Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed. 相似文献

In this paper, potential underlying mechanisms for massage therapy effects on preterm infant weight gain are reviewed. Path analyses are presented suggesting that: (1) increased vagal activity was associated with (2) increased gastric motility, which, in turn, was related to (3) greater weight gain; and (4) increased IGF-1 was related to greater weight gain. The change in vagal activity during the massage explained 49% of the variance in the change in gastric activity. And, the change in vagal activity during the massage explained 62% of the variance in the change in insulin. That the change in gastric activity was not related to the change in insulin suggests two parallel pathways via which massage therapy leads to increased weight gain: (1) insulin release via the celiac branch of the vagus; and (2) increased gastric activity via the gastric branch of the vagus. 相似文献

Although homework completion is said to be rather important to achievement, nowadays there is a growing concern of educators about the increasing number of students who do not engage properly on doing the homework tasks and the subsequent impact on school failure rates. Focusing on English as a Foreign Language (EFL) and using a sample of 591 Portuguese fifth and sixth graders, the present study analyses the role played by a number of homework variables on students' achievement (proximal and distal), and their mediating role on the use of self-regulated learning strategies and perceived self-efficacy in the domain. Data confirm the indirect effect of homework on school achievement, by means of the referred cognitive and motivational variables (use of self-regulated learning strategies and self-efficacy). These findings are further discussed in order to highlight the significant role homework completion can play on fighting school failure. 相似文献
