While several cognitive domains have been widely investigated in the field of aging, the age-related effects on tool use are still an open issue and hardly any studies on tool use and aging is available. A significant body of literature has indicated that tool use skills might be supported by at least two different types of knowledge, namely, mechanical knowledge and semantic knowledge. However, neither the contribution of these kinds of knowledge to familiar tool use, nor the effects of aging on mechanical and semantic knowledge have been explored in normal aging. The aim of the present study was to fill this gap. To do so, 98 healthy elderly adults were presented with three tasks: a classical, familiar tool use task, a novel tool use task assessing mechanical knowledge, and a picture matching task assessing semantic knowledge. The results showed that aging has a negative impact on tool use tasks and on knowledge supporting tool use skills. We also found that aging did not impact mechanical and semantic knowledge in the same way, confirming the distinct nature of those forms of knowledge. Finally, our results stressed that mechanical and semantic knowledge are both involved in the ability to use familiar tools. 相似文献

An earlier diagnosis and better overall multidisciplinary care enable people suffering from Cystic Fibrosis (CF) to have a life expectancy of 40. Consequently, new populations and questions about the development of the life of couples have arisen. This study by questionnaires takes a first look at marital adjustment, anxiety, depression, and emotion focused, social support focused, and problem focused coping strategies in 16 CF patients and their partners. As a whole, the couples' marital adjustment level was good; it was higher for men who were patients than men who were partners, and vice versa for women. Anxiety was high for at least one partner in 10 of the couples; depression, for at least one partner in seven of them. The participants seem to use coping strategies to a lesser extent than the general population. The results are discussed in terms of how the quality of life as a couple with one partner suffering from CF is affected by the proper mutual adjustment of the partners. 相似文献

Two experiments tested whether phonological phrase boundaries constrain online syntactic analysis in French. Pairs of homophones belonging to different syntactic categories (verb and adjective) were used to create sentences with a local syntactic ambiguity (e.g., [le petit chien mort], in English, the dead little dog, vs. [le petit chien] [mord], in English, the little dog bites, where brackets indicate phonological phrase boundaries). An expert speaker recorded the sentences with either a maximally informative prosody or a minimally informative one. Participants correctly assigned the appropriate syntactic category to the target word, even without any access to the lexical disambiguating information, in both a completion task (Experiment 1) and an abstract word detection task (Experiment 2). The size of the experimental effect was modulated by the prosodic manipulation (maximally vs. minimally informative), guaranteeing that prosody played a crucial role in disambiguation. The authors discuss the implications of these results for models of online speech perception and language acquisition. 相似文献

This prospective study evaluated the main and interactive effects of peritraumatic reactions with gender on posttraumatic stress disorder (PTSD) onset, independently of known risk factors. Further, 111 adult victims of violent crime completed the Structured Clinical Interview, the Modified PTSD Symptom Scale, the Peritraumatic Dissociative Experience Questionnaire, and the Peritraumatic Distress Inventory. Hierarchical regressions and chi-square tests were conducted for continuous and categorical measures of PTSD. Extremely elevated scores of peritraumatic dissociation (PD) and peritraumatic distress (PDI) were obtained for both sexes. Greater PDI and PD were related to more PTSD symptoms. No significant interaction effects with gender emerged. These results remained when acute stress disorder was controlled for. Analyses on categorical data produced similar results. Victims of violent crimes recall severe peritraumatic reactions. The more severe these are, the more likely they are to develop significant PTSD symptomatology in the months that follow. 相似文献

The ethical matrix is a participatory tool designed to structure ethical reflection about the design, the introduction, the development or the use of technologies. Its collective implementation, in the context of participatory decision-making, has shown its potential usefulness. On the contrary, its implementation by a single researcher has not been thoroughly analyzed. The aim of this paper is precisely to assess the strength of ethical matrixes implemented by a single researcher as a tool for conceptual normative analysis related to technological choices. Therefore, the ethical matrix framework is applied to the management of high-level radioactive waste, more specifically to retrievable and non-retrievable geological disposal. The results of this analysis show that the usefulness of ethical matrixes is twofold and that they provide a valuable input for further decision-making. Indeed, by using ethical matrixes, implicit ethically relevant issues were revealed—namely issues of equity associated with health impacts and differences between close and remote future generations regarding ethical impacts. Moreover, the ethical matrix framework was helpful in synthesizing and comparing systematically the ethical impacts of the technologies under scrutiny, and hence in highlighting the potential ethical conflicts. 相似文献

Recent works showed that tool use can be impaired in stroke patients because of either planning or technical reasoning deficits, but these two hypotheses have not yet been compared in the field of neurodegenerative diseases. The aim of this study was to address the relationships between real tool use, mechanical problem‐solving, and planning skills in patients with Alzheimer's disease (AD, n = 32), semantic dementia (SD, n = 16), and corticobasal syndrome (CBS, n = 9). Patients were asked to select and use ten common tools, to solve three mechanical problems, and to complete the Tower of London test. Motor function and episodic memory were controlled using the Purdue Pegboard Test and the BEC96 questionnaire, respectively. A data‐transformation method was applied to avoid ceiling effects, and single‐case analysis was performed based on raw scores and completion time. All groups demonstrated either impaired or slowed tool use. Planning deficits were found only in the AD group. Mechanical problem‐solving deficits were observed only in the AD and CBS groups. Performance in the Tower of London test was the best predictor of tool use skills in the AD group, suggesting these patients had general rather than mechanical problem‐solving deficits. Episodic memory seemed to play little role in performance. Motor dysfunction tended to be associated with tool use skills in CBS patients, while tool use disorders are interpreted as a consequence of the semantic loss in SD in line with previous works. These findings may encourage caregivers to set up disease‐centred interventions. 相似文献

Recent findings suggest that dispositional traits can influence personal affective forecasting. In this study, we investigated the relationship between dispositional happiness and affective prediction about academic performance among undergraduate students. Participants were asked to predict their emotional reactions on a 7-point Likert scale in regard to an important exam’s result two months prior obtaining their results. All the participants were contacted by SMS (Short Text Message) 8 h after the results were available and were requested to rate their actual emotional feelings on the same scale. According to their scores on the subjective happiness scale, participants were assigned into ‘happy’ and ‘unhappy’ groups. Results show no emotional prediction differences between the two groups for extreme results (i.e. good and bad results). In contrast, happy participants predicted less negative emotional feelings than unhappy ones for moderate results. No differences appear for the emotional feelings assessed the day they received their exam’s scores. These findings support the idea that dispositional happiness is related to emotional prediction and, more particularly, indicate that happiness induces more positive feelings concerning moderate future events, but not for extreme ones. This study suggests that happiness induces a positive view about emotional coping for future intermediate accomplishments only and not a positive view of the future in general. 相似文献

Destination memory refers to the recall of the destination of previously relayed information, and source memory refers to the recollection of the origin of received information. We compared both memory systems in Huntington's disease (HD) participants. For this, HD participants and healthy adults had to put 12 items in a black or a white box (destination task), and to extract another 12 items from a blue or a red box (source task). Afterwards, they had to decide in which box each item had previously been deposited (destination memory), and from which box each item had previously been extracted (source memory). HD participants showed poorer source as well as destination recall performance than healthy adults in the proposed tasks. Correlation analysis showed that destination recall was significantly correlated with episodic recall in HD participants. Destination memory impairment in HD participants seems to be considerably influenced by their episodic memory performance. 相似文献

Minimal understandings of populism focus on measuring explicit stances of antielitism and people centrism. What remains poorly understood is the way less overt forms of populist rhetoric enable leaders to emulate the language of common citizens to achieve electoral success. This article suggests that the study of the populist discourse also requires taking into account their implicit occurrences, that is, those conveying connect, closeness, commonness, and similarity with ordinary people. Expressed through performances of “layman likeness,” they enable populist politicians to dissociate from traditional ruling elites while enabling people leaders' identifications. Using a novel 261-million-word dataset of Indian political discourses—including the speeches of 11 Prime Ministers—to proxy such identifications, we argue that populist leaders rely on a mimesis of the common people. Three core mimetic speech items are quantified: intimacy, disintermediation, and simplicity. We use a replicable corpus-contextual multiword collocation technique to populate lexicons of pretested psychometric profiles as well as a threefold validation method. The analysis finds that current Prime Minister Narendra Modi communicates mimetic identification around his persona, indexing the linguistic markers of his stylistic, ideological, and institutional populist politics. We indicate that our context-aware method could also be of use to study the cross-regional variability of mimetic populism. 相似文献
