Object- and location-based inhibition of return in younger and older adults

When a cued object moves to new spatial coordinates, inhibition of return (IOR) with younger adults is found at the original cued location (location-based IOR) and at the current location of the object (object-based IOR). Older adults, however, show only location-based IOR. To determine whether this pattern of results represents a general age-related deficit in object-based IOR, the authors used static displays in which the placeholders (i.e., objects) were either present (location-based IOR+object-based IOR) or absent (location-based IOR only). Both age groups showed location-based IOR, but the older adults failed to show object-based IOR, consistent with age-related differences in visual pathways.     

Distinct mechanisms for planning keypress and reaching responses: a developmental study

This study examined developmental effects in the ability to use precue information for the planning of keypress and reaching responses. Participants from four age groups (7, 9, 13, and 21 year olds) performed a spatial precuing task either by pressing one of four response keys (keypress task) or by reaching directly toward one of the four target locations on the screen (reaching task). Reaction time data revealed striking age differences in the ability to use advance information in the keypress task, not in the reaching task. This dissociation confirms the hypothesis that distinct and separate mechanisms govern the planning of indirect keypress and direct reaching responses.     

The role of temporal and spatial factors in the covert orienting of visual attention tasks

There is a biphasic pattern in response times to peripheral uninformative cues, with faster responses to targets in cued locations when the stimulus onset asynchrony (SOA) is under 300 ms and slower responses when it is over 300 ms. The effect has typically been attributed entirely to the SOA while ignoring other aspects of the cues (duration, spatial configuration). To examine these other factors, along with SOA, the present experiments included manipulations of SOA (50, 100, 200, 400, 800 ms), inter-stimulus interval (ISI; 0, 50, 100, 150, 200, 300, 350, 400, 500, 600, 700, and 750 ms), and whether or not the cue and target overlap in the same space. The results indicate that cueing effects depend on the combination of cue duration, ISI, SOA, and the spatial configuration of the cues and targets. Three factors are used to explain these time course results.     

Inquiry and Analysis: Dewey and Russell on Philosophy

In an environment characterized by the emergence of new and diverse (and often opposed) philosophical efforts, there is a need for a conception of philosophy that will promote the exchange and critical consideration of divergent insights. Depending upon the operative conception, philosophical efforts can be viewed as significant, insightful and instructive, or unimportant, misguided and not real philosophy. This paper develops John Dewey's conception of philosophy as a mode of inquiry in contrast with Bertrand Russell's conception of philosophy as a mode of analysis. I argue that while Russell's analytic conception of philosophy justifies the dismissal of non-analytic philosophies, Dewey's conception of philosophy provides a theoretical framework for the comparison, evaluation and interaction of alternatives.     

Christian‐Muslim theological encounter: The priority of tawhid

Both Islam and Christianity are monotheistic faiths, yet the one God proclaimed and worshipped by each appears to be a different deity by virtue of the different conceptual construct that applies in each case. For Islam the defining motif is the idea of tawhld, for Christianity it is the notion of Trinity. In respect to theological dialogue between these two faiths the onus lies with the side holding the more complex construct to relate that back to the simpler and less complex, especially where the simpler motif is deemed to be contained within ike complex. Thus it behoves the Christian side to examine critically the trinitarian and related doctrines concerning the understanding of God, with a view to a clearer restatement of the essential oneness of deity which, after all, is the undergirding conceptual reference. In attempting this task, the ‘problematic of unity’ inherent in the Christian concept of God is addressed and a theological revision is suggested. The intention is to rethink critically aspects of Christian doctrine so as to further Christian‐Muslim theological dialogue, without in any way diminishing the essential insight of either side, but rather with a view to opening new lines of expression that each might equally affirm.

Environmentalism as a context for expressing identity and generativity: patterns among activists and uninvolved youth and midlife adults

Previous qualitative studies have identified themes of generativity and identity development in the interviews of environmental activists (Chan, 2009 ; Horwitz, 1996 ), suggesting their importance as motives for environmental behavior. The purpose of our study was to extend this work by identifying positive relationships between identity maturity, generativity, and environmentalism using quantitative methodologies. To explore these relationships, we designed quasi‐experimental and correlational studies. We recruited 54 environmental activists and 56 comparison individuals, half of whom were youth (mean age = 22 years) and the other half midlife adults (mean age = 43 years). Sixty‐three percent of our sample was female. Participants completed several environmental, generativity, and identity questionnaires. We found that activists and comparison individuals differed on the identity maturity, generativity, and environmental measures overall. Further, greater identity maturity and generativity were associated with higher environmental engagement. And generativity was found to mediate the relation between identity maturity and environmentalism. Our findings suggest that engaging in generative behaviors may be an important part of the process in forming an environmental identity and engaging in environmental actions.     

Rethinking community: Conservation,practice, and emotion

This paper focuses on the intersection of practice and emotion in collective environmental work. In recent years, “community” has become a central concept in conservation, reflecting the shift from top-down strategies to grassroots, participatory approaches. This community focus has generated abundant critique, especially in political ecology where scholars claim that normative notions of community clash with complex realities on the ground. I argue, however, that these critiques fail to fully grapple with the embodied materiality of togetherness and therefore remain too focused on preconceived social categories. Using the example of an international conservation fieldtrip from Chile to Costa Rica, I suggest that theories of practice and emotion can help remedy this problem in that they advance a performative understanding of being-in-common. I conclude by suggesting that such a formulation has implications for advancing collective environmental politics.
