This study focused on four aspects of parental monitoring of Internet use by their children: parental supervision, communication
and tracking, and adolescent disclosure. Data were obtained from a SAFT (Safety Awareness for Teens Project) national survey
of Singapore youths and parents regarding Internet safety at home. Study 1 examined 1,124 adolescents and 1,002 parents; Study
2 examined a subsample of 169 dyads of adolescents and their parents. Frequency of use and engagement in risky Internet behaviors
such as visiting inappropriate websites were analysed. The results indicated that parents tend to underestimate adolescents’
engagement in risky Internet behaviors and overestimate the amount of parental monitoring regarding Internet safety that occurs
at home. The study suggested that mothers have a better awareness of their adolescents’ Internet use than fathers. The findings
were explained in the context of parental monitoring. The results suggest that parental monitoring needs to be reconceptualized
and that parents need to improve the communication with their adolescents regarding Internet use. 相似文献

The neurocognitive structure of the acting self has recently been widely studied, yet is still perplexing and remains an often confounded issue in cognitive neuroscience, psychopathology and philosophy. We provide a new systematic account of two of its main features, the sense of agency and the sense of ownership, demonstrating that although both features appear as phenomenally uniform, they each in fact are complex crossmodal phenomena of largely heterogeneous functional and (self-)representational levels. These levels can be arranged within a gradually evolving, onto- and phylogenetically plausible framework which proceeds from basic non-conceptual sensorimotor processes to more complex conceptual and meta-representational processes of agency and ownership, respectively. In particular, three fundamental levels of agency and ownership processing have to be distinguished: The level of feeling, thinking and social interaction. This naturalistic account will not only allow to “ground the self in action”, but also provide an empirically testable taxonomy for cognitive neuroscience and a new tool for disentangling agency and ownership disturbances in psychopathology (e.g. alien hand, anarchic hand, anosognosia for one’s own hemiparesis). 相似文献

The current project is an initial attempt at validating the Virtual Reality Cognitive Performance Assessment Test (VRCPAT), a virtual environment-based measure of learning and memory. To examine convergent and discriminant validity, a multitrait-multimethod matrix was used in which we hypothesized that the VRCPAT's total learning and memory scores would correlate with other neuropsychological measures involving learning and memory but not with measures involving potential confounds (i.e., executive functions; attention; processing speed; and verbal fluency). Using a sequential hierarchical strategy, each stage of test development did not proceed until specified criteria were met. The 15-minute VRCPAT battery and a 1.5-hour in-person neuropsychological assessment were conducted with a sample of 30 healthy adults, between the ages of 21 and 36, that included equivalent distributions of men and women from ethnically diverse populations. Results supported both convergent and discriminant validity. That is, findings suggest that the VRCPAT measures a capacity that is (a) consistent with that assessed by traditional paper-and-pencil measures involving learning and memory and (b) inconsistent with that assessed by traditional paper-and-pencil measures assessing neurocognitive domains traditionally assumed to be other than learning and memory. We conclude that the VRCPAT is a valid test that provides a unique opportunity to reliably and efficiently study memory function within an ecologically valid environment. 相似文献

M. Singh and B. L. Anderson proposed a perceptual theory of achromatic transparency in which the perceived transmittance of a perceived transparent filter is determined by the ratio of the Michelson contrast seen in the region of transparency to that of the background seen directly. Subsequently, B. L. Anderson, M. Singh, and J. Meng proposed that Michelson contrast should be replaced by perceived contrast in this theory. However, their experimental stimuli were nongeneric (i.e., special cases), and their observers had little choice in their matching strategy. Here, the author shows that both of their ratio-of-contrasts theories are incorrect and that problems with their theoretical analyses and experimental designs led them to conclude that mean luminance does not affect perceived transmittance when contrast is held constant. The author also shows that B. L. Anderson's (2003) transmittance anchoring principle is not valid when a transparent surface is perceived to penetrate rather than overlay another surface. Finally, the author shows that M. Singh's (2004) theoretical proof that the ratio-of-Michelson-contrasts theory accurately predicts lightness matching through transparency is incorrect. 相似文献

Discretized multivariate normal structural models are often estimated using multistage estimation procedures. The asymptotic
properties of parameter estimates, standard errors, and tests of structural restrictions on thresholds and polychoric correlations
are well known. It was not clear how to assess the overall discrepancy between the contingency table and the model for these
estimators. It is shown that the overall discrepancy can be decomposed into a distributional discrepancy and a structural
discrepancy. A test of the overall model specification is proposed, as well as a test of the distributional specification
(i.e., discretized multivariate normality). Also, the small sample performance of overall, distributional, and structural
tests, as well as of parameter estimates and standard errors is investigated under conditions of correct model specification
and also under mild structural and/or distributional misspecification. It is found that relatively small samples are needed
for parameter estimates, standard errors, and structural tests. Larger samples are needed for the distributional and overall
tests. Furthermore, parameter estimates, standard errors, and structural tests are surprisingly robust to distributional misspecification.

We examined children’s behavioral coping in response to an in vivo peer rejection manipulation. Participants (N=186) ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (i.e., being voted out of the game) or non-rejection control. During a five-min. post-feedback waiting period children’s use of several behavioral coping strategies was assessed. Rejection elicited a marked shift toward more negative affect, but higher levels of perceived social competence attenuated the negative mood shift. Children higher in depressive symptoms were more likely to engage in passive and avoidant coping behavior. Types of coping were largely unaffected by gender and perceived social competence. Implications are discussed. 相似文献

The 9 members of the Institute for Rational-Emotive Therapy’s International Training Standards and Review Committee (of which
Albert Ellis is currently one) predict the status of Rational Emotive Behavior Therapy (REBT) after the death of Albert Ellis,
its progenitor. Most respondents addressed whether REBT will exist in its own right or be subsumed under the broad umbrella
of Cognitive Behavior Therapy.

Summary
Religious Faith and Criticism of Religion of Enlightenment. Restrictions of the Use of Reason in the Light of Critical Philosophy. In the this paper I analyse the present problem situation of the christian faith with respect to the assumption of the existence
of God and the role of Jesus and I criticize the problem-solutions offered by Bultmann, Ratzinger, Küng and Habermas. I try
to show that all these solutions imply a similar arbitrary restriction of the use of reason. 相似文献

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study. 相似文献

Marsh, Ward, and Landau (1999) demonstrated that participants asked to create novel words use elements of sample nonwords they are given, even when instructed to avoid use of the examples. In four studies, we replicated the effect of conformity to sample nonwords and found the effect was not influenced by the semantic category of the words unless those words shared orthographic characteristics. We found that although we could increase conformity to examples when word exemplars were grouped by category, it was likely that much of this increase was strategically driven. We propose that the presence of the sample non-words, presented in groups with the same word rules, created an orthographic category used by participants in the word creation task. 相似文献
