In this paper the results and implications of two studies of computer-supported collaborative learning are presented and implications discussed. The first study was an experimental study in a British secondary school, while the second study followed a group of primary school children in a naturalistic context. Assessing learning situations is discussed with an emphasis on the affective factors....

There is currently no agreement as to how specific or general are the mechanisms underlying newborns' face preferences. We address this issue by manipulating the contrast polarity of schematic and naturalistic face-related images and assessing the preferences of newborns. We find that for both schematic and naturalistic face images, the contrast polarity is important. Newborns did not show a pr...

I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for...

From Charles Darwin to Edward Wilson, evolutionary biologists have attempted to construct systems of evolutionary ethics. These attempts have been roundly criticized, most often for having committed the naturalistic fallacy. In this essay, I review the history of previous efforts at formulating an evolutionary ethics, focusing on the proposals of Darwin and Wilson. I then advance and defend a p...

The types of research pursued by occupational therapists have evolved in response to societal trends, external pressures, and the priorities of individual practitioners. Although many therapists have reconciled the pursuit of research with the roots o...

We present a method to measure the rate of information transfer for any continuous signals of finite duration without assumptions. After testing the method with simulated responses, we measure the encoding performance of Calliphora photoreceptors. We find that especially for naturalistic stimulation the responses are nonlinear and noise is nonadditive, and show that adaptation mechanisms affect...

Purpose Naturalistic speech samples should be routinely collected in the assessment of individuals with communication difficulties. However, even when these are collected, they often underutilized. We propose that analysis naturalistic can greatly enhance our understanding and evaluation functional impact primary progressive aphasia (PPA) on communication. First, we review current practices eva...
