A Christian Rationale for Vegetarianism

Abstract :  This article lays out an argument for vegetarianism based on a Christian theological rationale, specifically on a new articulation of a Christian anthropology for the 21^st century. What I suggest is that an exploration of what it means to be human in a contemporary first world context leads to the conclusion that vegetarianism is a logical expression of one's understanding of oneself as a Christian, and one's exercise of one's Christian faith and discipleship.     

Prioritizing Rights in the Social Justice Curriculum

The biggest problem facing schools having social justice curricula, beyond implementation of a programme, I claim, is the problem of justification: what grounds what in social justice and how do we make this manifest to ourselves and to the curricula? If we cannot address this, then social justice curricula are doomed to begging the question. I claim that a ranking of human rights is not only necessary to adjudicate competing claims for social justice and at the same time, thwart interference with already agreed-upon human rights: it is necessary for any curriculum of social justice for schools. That is to say, curricular programs of social justice cannot justify social practices that interfere with human rights, nor can they teach otherwise than this. Due attention to the violation of human rights is necessary, I shall argue, and must be central in the discussion of education for social justice.     

Adult Attachment Styles and Life Satisfaction in Individuals with Physical Disabilities

Examined the impact of adult attachment style on overall psychosocial adjustment among people with physical disabilities. 100 individuals with chronic, non-progressive physical disabilities living in the community. Adult attachment style, self-esteem, social integration and life satisfaction. Participants with physical disabilities did not differ from the general population in terms of secure versus insecure attachment styles represented. Secure attachment style predicted higher selfesteem. Both attachment security and physical independence were independently related to life satisfaction. This study highlights the importance of examining interpersonal relationships in life satisfaction in people with physical disabilities     

Facial identity and facial expression matching in 5–12‐year‐old children and adults

Facial identity and facial expression matching tasks were completed by 5–12‐year‐old children and adults using stimuli extracted from the same set of normalized faces. Configural and feature processing were examined using speed and accuracy of responding and facial feature selection, respectively. Facial identity matching was slower than face expression matching for all age groups. Large age effects were found on both speed and accuracy of responding and feature use in both identity and expression matching tasks. Eye region preference was found on the facial identity task and mouth region preference on the facial expression task. Use of mouth region information for facial expression matching increased with age, whereas use of eye region information for facial identity matching peaked early. The feature use information suggests that the specific use of primary facial features to arrive at identity and emotion matching judgments matures across middle childhood.

What is the Social Impact of ADHD in Girls? A Multi-Method Assessment

This study explores the social impact of ADHD, with and without opposition-defiant behaviour (ADHD+ODD (n= 22) and ADHD-only (n= 18)), in 9- to 12- year old girls compared to girls without ADHD (n= 40). Girls played a computer game involving simulated players, and mothers and teachers completed rating scales. In general, mothers and teachers saw girls with ADHD+ODD as more overtly and relationally aggressive and less prosocial than girls with ADHD-only, who were seen as more overtly and relationally aggressive and less prosocial than control girls. On the computer game, girls with ADHD+ODD were more overtly aggressive, more directly relationally aggressive, and showed less skilled behaviour than the other groups. Girls with ADHD-only showed less covert, indirect relational aggression and more socially awkward interactions than girls in the control group on the computer game. In all, the results indicate that girls with ADHD, with and without ODD behaviour, engage in socially detrimental behaviours.     

The exact variance of weighted kappa with multiple raters

Weighted kappa described by Cohen in 1968 is widely used in psychological research to measure agreement between two independent raters. Everitt then provided the exact variance for weighted kappa for two raters. In this paper, Everitt's exact variance is extended to three or more raters.     

Switching between simple cognitive tasks: the interaction of top-down and bottom-up factors.

How do top-down factors (e.g., task expectancy) and bottom-up factors (e.g., task recency) interact to produce an overall level of task readiness? This question was addressed by factorially manipulating task expectancy and task repetition in a task-switching paradigm. The effects of expectancy and repetition on response time tended to interact underadditively, but only because the traditional binary task-repetition variable lumps together all switch trials, ignoring variation in task lag. When the task-recency variable was scaled continuously, all 4 experiments instead showed additivity between expectancy and recency. The results indicated that expectancy and recency influence different stages of mental processing. One specific possibility (the configuration-execution model) is that task expectancy affects the time required to configure upcoming central operations, whereas task recency affects the time required to actually execute those central operations.     

Best face forward: Similarity effects in repetition priming of face recognition

Two experiments examined the graded similarity effect in the repetition priming of familiar face recognition. From the model of repetition priming proposed by Burton, Bruce, and Johnston (1990) it was predicted that similarity effects may be a confound of stimulus preparation. Experiment 1 was used to discount this hypothesis, but failed to replicate a pattern of graded priming related to the similarity of prime and target faces. Experiment 2 attempted a more extensive investigation using two different measures of prime-target similarity. The results replicated Ellis, Young, Flude, and Hay's (1987) finding that similar primes confer more priming than dissimilar ones, but found no correlation between amount of priming and the degree of prime-target resemblance for either similarity metric used. In view of these findings the mechanism of repetition priming in familiar face recognition is discussed.     

Driven to Distraction: Dual-Task Studies of Simulated Driving and Conversing on a Cellular Telephone

Dual-task studies assessed the effects of cellular-phone conversations on performance of a simulated driving task. Performance was not disrupted by listening to radio broadcasts or listening to a book on tape. Nor was it disrupted by a continuous shadowing task using a handheld phone, ruling out, in this case, dual-task interpretations associated with holding the phone, listening, or speaking. However, significant interference was observed in a word-generation variant of the shadowing task, and this deficit increased with the difficulty of driving. Moreover, unconstrained conversations using either a handheld or a hands-free cell phone resulted in a twofold increase in the failure to detect simulated traffic signals and slower reactions to those signals that were detected. We suggest that cellular-phone use disrupts performance by diverting attention to an engaging cognitive context other than the one immediately associated with driving.
