Most Norwegians are Internet users. We conducted a stratified probability sample study (Norway, 2007, age-group 16–74 years, N = 3,399, response rate 35.3%, 87.1% Internet users) to assess the prevalence of Internet addiction and at-risk Internet use by the Young Diagnostic Questionnaire (YDQ). The prevalence of Internet addiction (YDQ score 5–8) was 1.0% and an additional 5.2% were at-risk Internet users (YDQ score 3–4). Internet addiction and at-risk Internet use was strongly dependent on gender and age with highest prevalences among young males (16–29 years 4.1% and 19.0%, 30–39 years 3.3% and 10.7%). Logistic regression showed that male gender, young age, university level education, and an unsatisfactory financial situation were factors positively associated with "problematic Internet use" (at-risk and addicted use combined). Time spent on the Internet and prevalence of self-reported sleeping disorders, depression, and other psychological impairments increased linearly with YDQ score. Problematic Internet use clearly affects the lives of many people. 相似文献

We carried out three experiments aimed at testing whether hand posture affects the compatibility effect that Chen and Bargh
(1999) found between a word’s emotional connotation and arm movement direction. In the present study, participants responded
by pressing two buttons: one placed near their body, the other far away. In Experiment 1, in which they pressed the response
button with their hand open, RTs were shorter when participants pressed the far button for positive words and the near button for negative words, as if they simulated reaching for something good and avoiding something bad. However, in Experiments
2 and 3, in which participants pressed the response button with a tennis ball in their hand, RTs were shorter when participants
pressed the near button for positive words and the far button for negative words, as if they simulated drawing a good thing closer and pushing a bad thing away. Results are discussed
within the framework of theories on concept grounding in emotion and action systems. 相似文献

Clustering Qualitative Data Based on Binary Equivalence Relations: Neighborhood Search Heuristics for the Clique Partitioning Problem 总被引:2,自引:0,他引:2
The clique partitioning problem (CPP) requires the establishment of an equivalence relation for the vertices of a graph such
that the sum of the edge costs associated with the relation is minimized. The CPP has important applications for the social
sciences because it provides a framework for clustering objects measured on a collection of nominal or ordinal attributes.
In such instances, the CPP incorporates edge costs obtained from an aggregation of binary equivalence relations among the
attributes. We review existing theory and methods for the CPP and propose two versions of a new neighborhood search algorithm
for efficient solution. The first version (NS-R) uses a relocation algorithm in the search for improved solutions, whereas
the second (NS-TS) uses an embedded tabu search routine. The new algorithms are compared to simulated annealing (SA) and tabu
search (TS) algorithms from the CPP literature. Although the heuristics yielded comparable results for some test problems,
the neighborhood search algorithms generally yielded the best performances for large and difficult instances of the CPP. 相似文献

This article discusses large-scale assessment of change in student achievement and takes the study by Hickendorff, Heiser,
Van Putten, and Verhelst (2009) as an example. This study compared the achievement of students in the Netherlands in 1997 and 2004 on written division problems.
Based on this comparison, they claim that there is a performance decline in this subdomain of mathematics, and that there
is a move from applying the digit-based long division algorithm to a less accurate way of working without writing down anything.
In our discussion of this study, we address methodological challenges that come in when investigating long-term trends in
student achievements, such as the need for adequate operationalizations, the influence of the time of measurement and the
necessity of the comparability of assessments, the effect of the assessment format, and the importance of inclusion relevant
covariates in item response models. All these issues matter when assessing change in student achievement. 相似文献

There is evidence that we may be more likely to share stories about other people to the extent that they arouse emotion. If so, this emotional social talk may have important social consequences, providing the basis for many of our social beliefs and mobilising people to engage or disengage with the targets of the talk. Across three studies, we tested the situated communicability of emotional social information by examining if the ability of emotionality to increase communicability would depend on the emotion that was aroused and the identity of the audience. Study 1 showed that participants were more willing to share social anecdotes that aroused interest, surprise, disgust and happiness with an unspecified audience. Study 2 provided a behavioural replication of these findings. Study 3 showed that the communicability of emotional social talk did vary with audience identity (friend or stranger). Together, these findings suggest that emotional social events (particularly those that arouse disgust and happiness) are likely to become part of a society's social beliefs, with important consequences for the structure of social relationships.

Violations of social norms can either be evaluated in an absolute or in a gradual fashion depending on whether group goals are represented as minimal or maximal goals. Recent research has shown that absolute versus gradual deviations lead to increased levels of demanded punishment and inclination to exclude the deviant from the respective moral community. In this article, we investigate whether individual differences in orientation towards setting goals in either minimal or maximal terms predict reactions to norm violation. In three studies we found that a dominant minimal goal orientation (MIN) relative to maximal goal orientation (MAX) increased punishment inclinations and social exclusion tendencies towards norm violators. These effects were mediated by affective reaction and proved to be unique goal orientation effects when possible effects of need for closure, intolerance of ambiguity and regulatory focus were controlled for.

A connectionist model of the balance scale task is presented which exhibits developmental transitions between ‘Rule I’ and ‘Rule II’ behavior [Siegler, R. S. (1976). Three aspects of cognitive development. Cognitive Psychology,8, 481–520.] as well as the ‘catastrophe flags’ seen in data from Jansen and van der Maas [Jansen, B. R. J., & van der Maas, H. L. J. (2001). Evidence for the phase transition from Rule I to Rule II on the balance scale task. Developmental Review, 21, 450–494]. The model extends a connectionist model of this task [McClelland, J. L. (1989). Parallel distributed processing: Implications for cognition and development. In R. G. M. Morris (Ed.), Parallel distributed processing: Implications for psychology and neurobiology (pp. 8–45). Oxford: Clarendon Press] by introducing intrinsic variability into processing and by allowing the network to adapt during testing in response to its own outputs. The simulations direct attention to several aspects of the experimental data indicating that children generally show gradual change in sensitivity to the distance dimension on the balance scale. While a few children show larger changes than are characteristic of the model, its ability to account for nearly all of the data using continuous processes is consistent with the view that the transition from Rule I to Rule II behavior is typically continuous rather than discrete in nature. 相似文献

This study aims at discovering the essential constituents involved in the experiences of guilt and shame. Guilt concerns a
subject’s action or omission of action and has a clear temporal unfolding entailing a moment in which the subject lives in
a care-free way. Afterwards, this moment undergoes a reconstruction, in the moment of guilt, which constitutes the moment
of negligence. The reconstruction is a comprehensive transformation of one’s attitude with respect to one’s ego; one’s action;
the object of guilt and the temporal-existential experience. The main constituents concerning shame are its anchorage in the
situation to which it refers; its public side involving the experience of being perceptually objectified; the exclusion of
social community; the bodily experience; the revelation of an undesired self; and the genesis of shame in terms of a history
of frozen now-ness. The article ends with a comparison between guilt and shame. 相似文献
