Implicit attitudes toward children may be unrelated to child abuse risk

Objective

To explore whether adults possess implicit attitudes toward children and whether those attitudes are especially negative among respondents who are high in child physical abuse (CPA) risk.

Methods

The present study used an implicit evaluative priming procedure. In this procedure, participants were instructed to make decisions about the evaluative implications of target words. These words were preceded by photographs of child faces or adult faces displaying positive, neutral, or negative expressions. Reaction times for the evaluative decisions were used as an index of the extent to which photos invoked negative or positive evaluative reactions.

Results

Results from 2 studies, the first conducted on a student sample (N = 90) and the second on a parent sample (N = 95), demonstrated that evaluative congruence between the facial expressions displayed in photographs and the target words facilitated responses. Furthermore, the results suggested that regardless of CPA risk, child faces, relative to adult faces, facilitated responses to negative target words, suggesting an out-group bias. This implicit out-group bias was not moderated by respondents’ CPA risk status.

Conclusions

Faces of children, relative to faces of adults, appear to activate negative information structures that facilitate evaluative decisions of negative stimuli, suggesting an out-group bias. Given that out-group biases typically lead to less favorable treatment of out-group members, additional research is needed to examine the pervasiveness of negative evaluative biases towards children and the potential implications of such biases on children's lives. Further, research examining whether high CPA risk parents and low CPA risk parents differ in how they manage initial negative evaluative reactions is needed.

Another Perspective on Assessing the Significance of Information Technology in Education

Summary

The significance of information technology in education is usually assessed or evaluated on terms of some measures of effectiveness. In different school settings the effectiveness is operationalized in different ways, and in the literature various methods of determining the effectiveness have been discussed (e.g., Secretary's Conference on Educational Technology 1999). In this article, models for assessing the significance of information technology in education based on the teachers' subjective perspective are introduced. Theoretical backgrounds of the models are based on methods developed in information management science to assess the impact of information technology (IT) in industry and business. The first model is comprised of categorizing the rationales for using IT in education, the second model assesses the strategic impact of existing IT applications on one hand and of future IT applications on the other on education, and the third model assesses the roles of applications of IT in teaching. Also, the empirical findings of a small scale test of the two latter models in the Teacher Training School in Rauma (TTSR), a primary school in Finland with about 260 pupils and 19 teachers, are introduced.     

中国公民个人信息权保护现状

随着计算机和网络信息化的普及,个人信息可以轻易地在网络上被获取。而中国的许多公民由于传统习惯的影响,在社会的经济文化生活中,往往缺乏自我信息的保护意识,导致不法分子在获得公民个人信息后对公民信息权进行侵害。文章就我国公民个人信息权在日常生活中被侵害现状进行阐述,希望能够引起社会各界的广泛关注。
