The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine age‐related changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an ex‐Gaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher, and they also showed a higher distribution average except for the lower and higher presentation time. The results suggest a general slowdown in both tasks for age under different presentation times, except for the cases where presentation times were lower and higher. Moreover, if these parameters are understood to be a reflection of executive functions, these findings are consistent with the common view that age‐related cognitive deficits show a decline in this function.  相似文献

Most languages have a basic or "canonical" word order, which determines the relative positions of the subject (S), the verb (V), and the object (O) in a typical declarative sentence. The frequency of occurrence of the six possible word orders among world languages is not distributed uniformly. While SVO and SOV represent around 85% of world languages, orders like VSO (9%) or OSV (0.5%) are much less frequent or extremely rare. One possible explanation for this asymmetry is that biological and cognitive constraints for structured sequence processing make some word orders easier to be processed than others. Therefore, the high frequency of these word orders would be related to their higher learnability. The aim of the present study was to compare the learnability of different word orders between groups of adult subjects. Four artificial languages with different word orders were trained: two frequent (SVO, SOV) and two infrequent (VSO, OSV). In a test stage, subjects were asked to discriminate between new correct sentences and syntax or semantic violations. Higher performance rates and faster responses were observed for more frequent word orders. The results support the hypothesis that more frequent word orders are more easily learned.  相似文献

The low acceptance of influenza vaccination by both medical students and healthcare workers (HCWs) signals the need for innovative strategies. We administered an anonymous questionnaire to 410 University of Barcelona medical students who were asked about using the Internet to find information on influenza vaccination of HCWs and about their willingness to use technical and informal Facebook pages as an information channel on this topic. Of the 410 participants, 74.1 percent were female and 58.3 percent were in the first preclinical 3-year university cycle. A total of 7.6 percent participants reported using the Internet for queries on influenza vaccination, 89.8 percent reported that they were Facebook users, and 275 (67.1 percent) would accept an invitation from the technical or informal Facebook pages. The technical Web site would be actively followed by 77, or by 30.0 percent of those who would accept the invitation and the informal site by 116 (43.6 percent of those who would accept). The marked willingness to use Facebook to obtain information on the influenza vaccination of HCWs potentially opens a new window in health education: social networks could be used to help create professional habits. Students would be more likely to engage with this type of Facebook page if the contents were informal rather than highly technical.  相似文献

Although the participation of men in household activities has increased, this has not prompted an equitable division of household activities among men and women, since Spanish women continue to perform a greater share of these activities than Spanish men. This article explores the explanatory potential of three theoretical approaches (traditional gender division, role-strain and the resource-bargaining approach) to account for the emergence of different patterns in the division of unpaid work among Spanish dual earner couples. Using a representative sample of 2,877 Spanish workers and through logit ordered models, our study reveals that the three models contribute to the explanation of the different patterns of household labor and, therefore, may be regarded as complementary.  相似文献

In a series of 4 experiments, the authors show that phonological repair mechanisms, known to operate in the auditory modality, are directly translated in the visual modality. This holds with the provision that printed stimuli are presented for a very brief duration and that the effect of phonological repair is tested after a delay of some 100 ms has elapsed after that presentation. The case of phonological repair chosen to exemplify the parallelism between print and speech is the prosthesis of /e/ in utterances beginning with /s/ followed by a consonant in Spanish. Native speakers of Spanish hear a prothetic /e/ in auditorily presented pseudowords such as special (/speojal/, derived from "especial") as well as stuto (/stuto/, derived from "astuto"). It is shown here that they also hear that same vowel /e/ when presented with the printed pseudowords "special" and "stuto." This finding of a phonological repair effect in print has implications for the issue of phonological activation from print, as well as for the prelexical locus and mandatory nature of phonological repair mechanisms in general.  相似文献

Positive and negative alliance‐related behaviours of thirty‐seven families seen in brief family therapy were rated from videotapes using the System for Observing Family Therapy Alliances ( Friedlander et al., 2006b ). Positive associations were found between in‐session behaviour and participants' perceptions of the alliance and improvement so far both early (session 3) and later in therapy (session 6). Binary logistic regression showed that successful outcomes (defined as consensus by therapist and all family members on general improvement and reduced problem severity) were significantly predicted by positive individual behaviour (Engagement in the Therapeutic Process, Emotional Connection with the Therapist, Safety within the Therapeutic System) in session 3 and productive within‐family collaboration (Shared Sense of Purpose within the Family) in session 6. Shared Sense of Purpose was the alliance indicator most consistently associated with clients' and therapists' perceptions of therapeutic progress; moreover, it was the only alliance indicator to improve significantly over time in treatment.  相似文献

Temporal logic is one of the many areas in which a possible world semantics is adopted. Prior's Ockhamist and Peircean semantics for branching-time, though, depart from the genuine Kripke semantics in that they involve a quantification over histories, which is a second-order quantification over sets of possible worlds. In the paper, variants of the original Prior's semantics will be considered and it will be shown that all of them can be viewed as first-order counterparts of the original semantics.  相似文献

Tim Crane has maintained that intentional objects are to be conceived of as schematic entities, having no particular intrinsic nature. While I take this metaphysical thesis to be correct, I cast doubt on whether it excludes intentionalia, especially non-existent ones, from the general inventory of what there is, as Crane seems to think it does. There is a tension here, since Crane uses intentionalia in order to individuate intentional states, but at the same time attempts to dispense with them. If my doubts are grounded, the tension disappears.  相似文献

In this paper, I want to deal with the problem of how to find an adequate context of interpretation for indexical sentences that enables one to account for the intuitive truth-conditional content which some apparently puzzling indexical sentences like “I am not here now” as well as other such sentences contextually have. In this respect, I will pursue a fictionalist line. This line allows for shifts in interpretation contexts and urges that such shifts are governed by pretense, which has to be understood in terms of socially shared make-believe games. By appealing to pretense so conceived, I will show that the fictionalist perspective is halfway between an intentionalist perspective, according to which the above indexical sentences have to be interpreted in a shifted intended context, (this perspective is primarily defined by Predelli 1998, Analysis 58, 107; Mind and Language 13, 400) and a conventionalist perspective, according to which indexical reference shifts in accordance with a conventional setting. (For this perspective, cf. Corazza et al. 2002, Philosophical Studies 107, See also Corazza 2004, Reflecting the Mind: Indexicality and Quasi-Indexicality, Oxford University Press). Finally, I will claim that the fictionalist analysis of cases of non-ordinary uses of indexicals like “here” and “now” can be retained in face of a new alternative analysis of those cases in terms of an ‘unbound anaphora’ – theory (cf. Corazza 2004, Synthese 138, 145).  相似文献

In a journal entry from 1906, Husserl complains of lacking “internal stability” and of his desire to “achieve” it. My claim in this paper is that the “phenomenological method,” which he made public in his 1907 lectures Die Idee der Phänomenologie was, and is, a means to achieve the inner harmony that Husserl longed for. I do not provide an analysis of why Husserl might have felt the way he did; my aim is to show what internal stability might be and how one might achieve it. I conclude that the phenomenological method is the means, the “how,” to internal stability, which I characterize as “clarity” and “harmony” regarding our beliefs and, and ultimately, our authentic comportment.  相似文献
