An experimental comparison of viewpoint-specific and viewpoint-independent models of object representation

Four experiments that investigate the cognitive representation of objects in human observers are reported. Two broad classes of theory were examined: viewpoint-specific and viewpoint-independent models. The former postulate that the data structures underpinning object recognition correspond to discrete views and require additional processing to access them from unfamiliar viewpoints. The latter postulate data structures that are independent of any particular viewpoint and can be directly accessed from a wide range of viewpoints. Two experimental tasks were used: a sequential matching paradigm and a cognitive learning paradigm. Findings favour viewpoint-specific models over viewpoint-independent models.     

I Love to Tell the Story: Reshaping the Narrative of Adoption

Abstract : This article argues that a Christian theological understanding of adoption can be a helpful corrective to some of the negative interpretations and assumptions around adoption that continue to circulate in secular culture. The article proceeds as follows: First, I argue that the way in which Christians understand and describe the experience of being adopted into God's family counters the idea that one's birth family is one's “real” family. Second, I argue that a Christian understanding of adoption mitigates the tendency to view adoption as a sort of “Plan B.” Finally, I argue that because of the value Christians place on caring for those in need, and the replacement of kin relationships with relationships of love and faith, the metaphor of adoption can and should be used more widely, to create broader networks of family that encompass far more than mere blood ties.     

The Optimality of Tax Transfers: What does Life Satisfaction Data Tell Us?

This paper addresses an important policy question: who gets the largest utility gain from income and does the tax system adequately reflect this? We address this question by using Australian panel data and taking life satisfaction as a proxy for utility, allowing us to identify the marginal utility of additional income for different groups of individuals. We find that optimal transfers consist of transfers from the old to the middle aged, and from the married to the unmarried. This optimal utilitarian welfare policy is then contrasted with information on who actually receives transfers and who pays for them in Australia, where we find that taxes are too high for some groups, like the young, and that they are too low for other groups, like the elderly. We believe that the methodology developed in this paper could be fruitfully applied to the issue of optimal taxation in other countries.     

Parenting and Conduct Problems: Moderation by Child Empathy

Child empathy was examined as a moderator of the relations between positive and negative parenting behavior and child conduct problems. Participants were 56 mother-child dyads (child age M?=?10.8 years; 64 % male) and children were recruited with a range of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms. Parenting was assessed by direct observations of mothers’ praise and criticism during parent–child interactions and child empathy was measured with mother report. Child conduct problems were assessed via observation and mother-report measures, and a composite variable was created. In regression analyses, child ADHD symptoms were uniquely related to child conduct problems. Second, as hypothesized, child empathy moderated the relations between parenting and conduct problems. Mother praise was negatively related to child conduct problems at lower levels of child empathy, but this relation was not significant at higher levels of child empathy. On the contrary, mother criticism was positively related to child conduct problems at high levels of child empathy, but this relation was not significant at low levels of empathy. The results suggest that different types of parenting behavior may be differentially beneficial to children, depending on their level of empathy.
