Semantic effects in visual word detection with visual similarity controlled

In three experiments, subjects searched through word lists for a single target word. Search was faster when the target word belonged to a different semantic category from that of the background words with visual similarity controlled. This semantic effect increased with number of items to be searched through, and it obtained whether the target was cued visually or verbally. Semantic homogeneity within the background also speeded search, but only when subjects had no prior knowledge of the nature of a list. Several models of the semantic effect are described. All contrast the encoding of physical identity with the encoding of semantic attributes, but they differ in ascribing the effect to: (1) the relative access times for these codes, (2) the power of the codes in dealing with multiple comparisons, or (3) the attentional demands of comparison using different levels of code.     

How long do the advantages of learning to read a transparent orthography last? An investigation of the reading skills and reading impairment of Welsh children at 10 years of age

Spencer and Hanley (2003) showed that Welsh-speaking children aged between 5 and 7 years who were learning to read Welsh (a transparent orthography) performed significantly better at reading both real words and nonwords than did English-speaking children living in Wales who were learning to read English (a deep orthography). In this study, the reading skills of these children were reexamined three years later, during their sixth year of formal reading instruction. The children learning to read English continued to perform poorly at reading low- and medium-frequency irregular words but no differences were observed in reading regular words or nonwords. These findings emphasize how long it takes to acquire a large sight vocabulary in English, but indicated that the reading skills of the majority of the English-speaking children had caught up with those of their Welsh-speaking counterparts. However, the poorest 25% of the English readers continued to perform much worse than the lowest performing 25% of Welsh readers on both words and nonwords. An underachieving tail of this kind was not observed in the reading performance of the Welsh-speaking group. Overall, these findings suggest that in the long term the detrimental effects of an opaque orthography are most damaging to the poorest readers.     

CHRISTIAN AND BUDDHIST PERSPECTIVES ON NEURO PSYCHOLOGY AND THE HUMAN PERSON: PNEUMA AND PRATITYASAMUTPADA

Abstract. Recent discussions of the mind‐brain and the soul‐body problems have been both advanced and complexified by the cognitive sciences. I focus explicitly here on emergence, supervenience, and nonreductive physicalist theories of human personhood in light of recent advances in the Christian‐Buddhist dialogue. While traditional self and no‐self views pitted Christianity versus Buddhism versus science, I show how the nonreductive physicalist proposal regarding human personhood emerging from the neuroscientific enterprise both contributes to and is enriched by the Christian concept of pneuma (spirit) and the Buddhist concept of pratityasamutpada (codependent origination).     

Can treatment trial samples be representative?

A catchment area-based sample of patients recruited for an eating disorder treatment trial was compared with patients from the same geographical area seen in the 12 months before and after the trial. The three samples were very similar. The research sample was representative of the usual clinic sample from which it had been selected and thus the results could be extrapolated with some confidence to other similar clinical settings. It is concluded that whilst treatment trials, by their very nature, have explicit and implicit inclusion and exclusion criteria with appropriate designs they can be usefully representative.     

Reviewing policies on satellite broadcasts in east asia: New technology,political economy,and civil society

As an instrument of national integration, domestic television in many post-colonial countries has long neglected cultural minorities. Transnational television via newer satellite and cable technologies has been able to target cross-border ethnic groups which then constituted viable audience markets. Governments in Asia sought initially to control access to transnational broadcasts out of paternalistic nationalism, but audiences and entrepreneurs have circumvented such policies. Thus over the last decade the political economy of television in countries such as Malaysia, Philippines and Thailand have been transformed, though in differing ways. Belated media deregulation has often led to alliances between business and political elites. This paper argues that most policy developments in Asian television have been driven by business and government imperatives rather than by civil society involvement.

His eclectic research interests include the political economy of international communications, globalization/transnationalization strategies, cross-cultural dimensions in marketing and management, and ethical issues in post-industrial society.

Effects of psychopathy traits on unprovoked aggression

Research has demonstrated that risk of violent behavior is high in individuals who display psychopathic traits. However, prediction of general aggression, and in particular unprovoked aggression, in nonforensic men who possess such traits has received little experimental attention to date. This study examined the role of psychopathic traits in the prediction of unprovoked aggression in a nonforensic sample. One hundred and five men completed the Levenson Self-Report Psychopathy Scales and competed in a sham aggression paradigm. These men were identified as unprovoked aggressors, provoked aggressors, and provoked nonaggressors contingent on their responses to the experimental paradigm. Findings indicated that men with high levels of psychopathic traits had a 30% greater probability of becoming aggressive in the absence of provocation relative to those with lower psychopathic traits. Results also indicated that unprovoked aggressors evinced more general aggression when provocation was initiated. Findings are discussed in terms of the importance of trait-based risk factors in the prediction of seemingly random, unprovoked aggression.
