Following previous work on the spiritual health of secondary students, the author wondered if it was possible to develop a spiritual health measure for younger children. Taking Fisher's model of spiritual health as the basis, items were developed to reflect relationships with self, with others, with the environment and with a god. The children's ideals for spiritual health (what makes them Feel Good) were compared with their lived experience (Living Life) to ascertain their levels of spiritual health. Factor analyses on responses from 1080 students in 14 schools (State, Catholic, Independent and Christian Community Schools) in Victoria and Western Australia are reported in this paper. 相似文献

Prior studies have indicated that post-encoding stress can protect memories from the effects of forgetting, and this has been taken as evidence that stress facilitates memory consolidation. However, it is not known whether stress acts by directly influencing the strength of the underlying memories or whether it influences the generation process that plays a critical role in tests such as free recall. To address this issue, we examined the effects of stress produced by skydiving on recognition memory for negative and neutral pictures. Relative to a non-stress control condition, post-encoding stress in males was found to increase recognition memory for neutral pictures. However, stress was not found to improve recognition for emotional pictures, nor was it found to influence recognition memory in female participants. Additional analysis of recognition performance suggested that stress increased familiarity-based recognition rather than recollection. This study indicates that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories. 相似文献

Engineers must deal with risks and uncertainties as a part of their professional work and, in particular, uncertainties are
inherent to engineering models. Models play a central role in engineering. Models often represent an abstract and idealized
version of the mathematical properties of a target. Using models, engineers can investigate and acquire understanding of how
an object or phenomenon will perform under specified conditions. This paper defines the different stages of the modeling process
in engineering, classifies the various sources of uncertainty that arise in each stage, and discusses the categories into
which these uncertainties fall. The paper then considers the way uncertainty and modeling are approached in science and the
criteria for evaluating scientific hypotheses, in order to highlight the very different criteria appropriate for the development
of models and the treatment of the inherent uncertainties in engineering. Finally, the paper puts forward nine guidelines
for the treatment of uncertainty in engineering modeling. 相似文献

Nouns are generally easier to learn than verbs (e.g., Bornstein, 2005; Bornstein et al., 2004; Gentner, 1982; Maguire, Hirsh-Pasek, & Golinkoff, 2006). Yet, verbs appear in children's earliest vocabularies, creating a seeming paradox. This paper examines one hypothesis about the difference between noun and verb acquisition. Perhaps the advantage nouns have is not a function of grammatical form class but rather related to a word's imageability. Here, word imageability ratings and form class (nouns and verbs) were correlated with age of acquisition according to the MacArthur-Bates Communicative Development Inventory (CDI) (Fenson et al., 1994). CDI age of acquisition was negatively correlated with words' imageability ratings. Further, a word's imageability contributes to the variance of the word's age of acquisition above and beyond form class, suggesting that at the beginning of word learning, imageability might be a driving factor. 相似文献

Our aim in the present study was to identify key components of physical appearance among young Thai women. Free listings, focus groups and pile sorting were used. One-hundred twenty young women generated 78 unique physical appearance characteristics. Ninety-four nursing students validated these characteristics in focus groups and then sorted them into piles that reflected separate domains of physical appearance and labeled them. Salience analysis revealed that facial appearance (e.g., bright facial skin, high nose bridge, big eyes) was the most important domain, followed by body weight and shape, skin color and texture, hair (color, texture, length), and ‘other’ physical appearance (e.g., slender neck, slim fingers). This is the first study to identify aspects of physical appearance that are most salient to young Thai women and that may differ from women in other cultural contexts. These findings could be used to develop culturally grounded measures of physical appearance in Thai women. 相似文献

A Dialectical Behavior Therapy Skills training manual (DBT Skills) was adapted for use with caregivers of individuals with dementia. Implementation occurred in a community clinic with a heterogeneous caregiver group at risk for elder abuse. Sixteen caregivers completed the 9-week group. The results point to improved psychosocial adjustment, particularly increased problem-focused coping, enhanced emotional well-being, and less fatigue. Caregivers tended to utilize individual therapeutic services at a higher rate during the period of group attendance, indicative of appropriate help-seeking behavior in highly demanding situations. Six of the 16 caregivers repeated the training sequence in “booster” groups. Follow-up data from the booster groups suggest that high-risk caregivers may require continuing support to maintain treatment gains. In addition to demonstrating the feasibility of DBT Skills with caregivers, the results warrant a controlled outcome evaluation. 相似文献

Harvey's cognitive model of insomnia (2002a) proposes that sleep-related safety behaviors play a central role in the maintenance of insomnia because such maladaptive coping strategies are thought to reinforce threat-based appraisals of the likelihood and consequences of poor sleep. Research to date has assessed the frequency of safety behavior use in those with insomnia only; however, in addition to the frequency of occurrence, the function of safety behaviors (i.e., a belief that they will prevent a feared outcome from occurring), may be an important consideration. The purpose of this study was to examine sleep-related safety behaviors based on an expanded theoretical understanding of such behaviors across psychological disorders; that is, by examining both their frequency and perceived utility. Undergraduate students (N = 376) completed an online survey about their sleep, mood, and use of sleep-related safety behaviors. Insomnia severity was associated with a greater perceived need to use safety behaviors (i.e., utility) but not with frequency of safety behavior use. Higher perceived utility of safety behaviors was also associated with unhelpful beliefs about sleep, fear and avoidance of fatigue, and both general and sleep-specific helplessness. These results suggest that these behaviors and the associated underlying maladaptive beliefs may be important targets in cognitive behavioral therapy for insomnia. The current study extends the existing literature and refines the concept of safety behaviors in insomnia to include both the function and frequency of these behaviors. 相似文献

Successful social interactions rely on the ability to make accurate judgments based on social cues as well as the ability to control the influence of internal or external affective information on those judgments. Prior research suggests that individuals with schizophrenia misinterpret social stimuli and this misinterpretation contributes to impaired social functioning. We tested the hypothesis that for people with schizophrenia, social judgments are abnormally influenced by affective information. Twenty-three patients with schizophrenia and 35 healthy control participants rated the trustworthiness of faces following the presentation of neutral, negative (threat-related), or positive affective primes. Results showed that all participants rated faces following negative affective primes as less trustworthy than faces following neutral or positive primes. Importantly, this effect was significantly more pronounced for participants with schizophrenia, suggesting that schizophrenia may be characterized by an exaggerated influence of negative affective information on social judgment. Furthermore, the extent that the negative affective prime influenced trustworthiness judgments was significantly associated with patients' severity of positive symptoms, particularly feelings of persecution. These findings suggest that for people with schizophrenia, negative affective information contributes to an interpretive bias, consistent with paranoid ideation, when judging the trustworthiness of others. This bias may contribute to social impairments in schizophrenia. 相似文献

Is processing of conceptual information as robust as processing of perceptual information early in development? Existing empirical evidence is insufficient to answer this question. To examine this issue, 3- to 5-year-old children were presented with a flexible categorization task, in which target items (e.g., an open red umbrella) shared category membership with one test item (e.g., a folded umbrella) and perceptual characteristics with another test item (e.g., a red mushroom). Participants were instructed to either categorize stimuli by the same dimension (i.e., perceptual similarity or category membership) in both phases of the task, or switch from categorizing by one dimension to categorizing by the other dimension. Results pointed to a strong asymmetry in switch costs: conceptual switch costs were higher than perceptual switch costs. These results suggest that processing of perceptual information remains more robust than processing of conceptual information at least until 5 years of age. 相似文献
