Children’s movement is an important issue in child development and outcome in early childhood research, intervention, and practice. Digital sensor technologies offer improvements in naturalistic movement measurement and analysis. We conducted validity and feasibility testing of a real-time, indoor mapping and location system (Ubisense, Inc.) within a preschool classroom. Real-time indoor mapping has several implications with respect to efficiently and conveniently: (a) determining the activity areas where children are spending the most and least time per day (e.g., music); and (b) mapping a focal child’s atypical real-time movements (e.g., lapping behavior). We calibrated the accuracy of Ubisense point-by-point location estimates (i.e., X and Y coordinates) against laser rangefinder measurements using several stationary points and atypical movement patterns as reference standards. Our results indicate that activity areas occupied and atypical movement patterns could be plotted with an accuracy of 30.48 cm (1 ft) using a Ubisense transponder tag attached to the participating child’s shirt. The accuracy parallels findings of other researchers employing Ubisense to study atypical movement patterns in individuals at risk for dementia in an assisted living facility. The feasibility of Ubisense was tested in an approximately 90-min assessment of two children, one typically developing and one with Down syndrome, during natural classroom activities, and the results proved positive. Implications for employing Ubisense in early childhood classrooms as a data-based decision-making tool to support children’s development and its potential integration with other wearable sensor technologies are discussed. 相似文献

A brief historical and philosophical analysis suggests that the biomedical model and prevention have been the pillars of health
promotion practices with the underlying assumption that these concepts provide answers to people’s health woes. Another observation
resulting from this analysis is that biomedical, prevention, and more recently, wellness, do not differ much from each other
paradigmatically (e.g., instrumental rationality) and, hence, are severely restricted in their short- and long-term effectiveness
for helping people with healthy living and quality of life. It is proposed that eudaimonic well-being—if explored, understood,
and implemented in a manner that holds true to the purity of the concept—offers significant promise for shifts in health promotion
practices that may lead to transformative health experiences and enhanced quality of life. 相似文献

In a location-based negative priming task, targets that appear at locations that were previously occupied by distractors are typically responded to more slowly than are targets that appear at formerly unoccupied positions. In the present study, we attempted to disengage the location-based negative priming mechanism by presenting visual cues indicating the most likely location of the upcoming target. The first experiment showed that 75% cue-target validity was not sufficient to affect the negative priming mechanism. However, the second experiment demonstrated that a much reduced, but not eliminated, negative priming effect occurred with 100%cue-target validity. These findings are similar to those found with inhibition of return, suggesting that location-based inhibition of return effects and location-based negative priming effects may share a common inhibition mechanism. 相似文献

Previous research on the interaction between manual action and visual perception has focused on discrete movements or static postures and discovered better performance near the hands (the near-hand effect). However, in everyday behaviors, the hands are usually moving continuously between possible targets. Therefore, the current study explored the effects of continuous hand motion on the allocation of visual attention. Eleven healthy adults performed a visual discrimination task during cyclical concealed hand movements underneath a display. Both the current hand position and its movement direction systematically contributed to participants’ visual sensitivity. Discrimination performance increased substantially when the hand was distant from but moving toward the visual probe location (a far-hand effect). Implications of this novel observation are discussed. 相似文献

Smoking cessation among pregnant adolescents remains a complex and unresolved issue. The purpose of this study was to examine adolescents' knowledge of the detrimental effects of smoking on pregnant women and fetuses and its relationship to efforts to quit smoking. The sample consisted of 71 pregnant adolescents, and a three-group randomized intervention design-Teen FreshStart (TFS), Teen FreshStart with buddy (TFSB), and usual care control (UCC)-was used. Instruments included a demographic questionnaire, a smoking history questionnaire, and an 11-item scale measuring knowledge of the effects of smoking during pregnancy. For the entire sample, knowledge scores increased significantly (p = .000) from T1 (preintervention) to T2 (postintervention), and the adolescents who quit smoking had significantly higher knowledge at T2 (p = .028) and greater increases (T1 to T2) in their knowledge (p = .019) than did those who did not quit. Together, the TFS and TFSB groups had significantly higher knowledge at T2 (p = .017) and a significantly greater increase in knowledge from T1 to T2 (p = .005) than did the UCC group. This also held true when the TFS and TFSB groups were examined individually. Each had significantly higher knowledge at T2 (TFS, p = .029; TFSB, p = .008) and a significantly greater increase in knowledge from T1 to T2 (TFS, p = .007; TFSB, p = .009) than did the UCC group. Furthermore, despite the small sample sizes, within-group comparisons showed (a) no significant differences between quitters and nonquitters in the UCC group, (b) significantly higher knowledge at T2 (p = .052) and a trend indicating greater increases in knowledge from T1 to T2 (p = .092) for the quitters compared with the nonquitters in the TFS group, and (c) a trend for adolescents in the TFSB group who quit smoking to have greater increases in knowledge compared with those who did not quit (p = .158). These results indicate the need for continued inquiry into the relationship between pregnant teenagers' health knowledge and decisions to stop smoking. 相似文献

According to Hume, the idea of a persisting, self-identical object, distinct from our impressions of it, and the idea of a
duration of time, the mere passage of time without change, are mutually supporting "fictions". Each rests upon a "mistake",
the commingling of "qualities of the imagination" or "impressions of reflection" with "external" impressions (perceptions),
and, strictly speaking, we are conceptually and epistemically entitled to neither.
Among Kant's aims in the First Critique is the securing of precisely these entitlements. Like Hume, he acknowledges the correlativity of the notions of temporal
duration and persisting self-identical objects (i.e., continuant substances). Unlike Hume, however, he undertakes to establish
the legitimacy or objective validity of the schematized category of substance and, correspondingly, of the representation of time as a formal unity with duration
as one of its modes.
This essay formulates Hume's problem and then explores Kant's complex argument for the legitimacy of our concepts of substantial
identity and temporal duration, from its origins in his accounts of the forms of inner and outer sense and the transcendental
unity of apperception through the Transcendental Deduction of the unschematized category of inherence and substance and its
schematized counterpart, substance as permanence, in the First Analogy.

The process of making judgments and decisions requires a method for combining data. To compare the accuracy of clinical and mechanical (formal, statistical) data-combination techniques, we performed a meta-analysis on studies of human health and behavior. On average, mechanical-prediction techniques were about 10% more accurate than clinical predictions. Depending on the specific analysis, mechanical prediction substantially outperformed clinical prediction in 33%-47% of studies examined. Although clinical predictions were often as accurate as mechanical predictions, in only a few studies (6%-16%) were they substantially more accurate. Superiority for mechanical-prediction techniques was consistent, regardless of the judgment task, type of judges, judges' amounts of experience, or the types of data being combined. Clinical predictions performed relatively less well when predictors included clinical interview data. These data indicate that mechanical predictions of human behaviors are equal or superior to clinical prediction methods for a wide range of circumstances. 相似文献

Where we make ocular fixations when viewing an object likely reflects interactions between 'external' object properties and internal 'top-down' factors, as our perceptual system tests hypotheses and attempts to make decisions about our environment. These scanning fixation patterns can tell us how and where the visual system gathers information critical to specific tasks. We determined the effects of the internal factors of expertise, experience, and ambiguity on scanning during a face-recognition task, in eight subjects. To assess the effects of expertise, we compared upright with inverted faces, since it is hypothesized that inverted faces do not access an orientation-dependent face-expert processor. To assess the effects of experience, we compared famous with novel faces, as famous faces would have stronger internal representations than anonymous ones. Ambiguity in matching seen and remembered faces was manipulated with morphed faces. We measured three classes of variables: (i) total scanning time and fixations; (ii) the spatial distribution of scanning; and (iii) the sequence of scanning, using first-order Markov matrices for local scan structure and string editing for global scan structure. We found that, with inverted faces, subjects redistributed fixations to the mouth and lower face, and their local and global scan structure became more random. With novel or morphed faces, they scanned the eyes and upper face more. Local scan structure was not affected by familiarity, but global scan structure was least random (most stereotyped) for novel upright faces. We conclude that expertise (upright faces) leads to less lower-face scanning and more predictable global patterns of information gathering. Experience (famous faces) leads to less upper-face scanning and more idiosyncratic global scan structures, suggesting a superseding influence of facial memories. With morphed faces, subjects return to the upper face to resolve ambiguity, implying a greater importance of this region in face recognition. 相似文献

Empirical evidence suggests that television and other media influence adolescents' attitudes and behaviors. Much of the research in this area is based on surveys in which adolescents are asked to rank the relative importance of a fixed set of factors such as parents, peers, and media. We reviewed data from focus groups conducted with adolescents and their parents to examine the extent to which adolescents identify--without prompting--media as a source of influence on sexual behavior. Adolescents seemed indifferent to media influence (e.g., media influence was mentioned in only one adolescent focus group), but their parents expressed significant concern about media influence. Future research should investigate the extent to which influences exist outside of adolescents' consciousness. For now, parents and sexuality educators may need to convince adolescents that concerns about the media are valid before trying to change media-influenced behavior. 相似文献
