The Dragonfly’s Web: Courseware for children created by college students on the World-Wide Web

We describe a successful approach to teaching first-year undergraduates to produce World-Wide Web courseware. Students were responsible for coding, writing, graphics, research, and theory. We taught that courseware should elicit higher order cognitive processes such as problem solving, application, synthesis, and critical thinking in children. It appears that the exercise facilitated experiential learning, the application of theories of learning, and courseware and hypertext design, as well as promoting critical thinking in our undergraduates. We argue that psychology students can and should develop useful Web pages as a learning experience and service to the field.     

Using AGENDA for qualitative data analysis

Computerized approaches to qualitative analysis have lagged significantly behind comparable developments in quantitative analysis. AGENDA, a PC-based, free-form database package, manipulates text as data, performs the basic tasks of qualitative data analysis, and satisfies the criteria of computerized field research methods. AGENDA's contributions to qualitative research outweigh its limitations.     

Guided search: an alternative to the feature integration model for visual search

Subjects searched sets of items for targets defined by conjunctions of color and form, color and orientation, or color and size. Set size was varied and reaction times (RT) were measured. For many unpracticed subjects, the slopes of the resulting RT X Set Size functions are too shallow to be consistent with Treisman's feature integration model, which proposes serial, self-terminating search for conjunctions. Searches for triple conjunctions (Color X Size X Form) are easier than searches for standard conjunctions and can be independent of set size. A guided search model similar to Hoffman's (1979) two-stage model can account for these data. In the model, parallel processes use information about simple features to guide attention in the search for conjunctions. Triple conjunctions are found more efficiently than standard conjunctions because three parallel processes can guide attention more effectively than two.     

Self-monitoring and the association between confidence and accuracy

A personality prediction task in which a confidence rating accompanies each judgment is used to test the hypotheses that self-monitoring is positively related to accuracy, positively related to confidence, negatively related to calibration, and capable of acting as a moderator of the relationship between accuracy and confidence. Data from 101 university students support two of these predictions: High self-monitors exhibit more confidence and poorer calibration than low self-monitors. Concern for appropriateness is found to be unrelated to all other variables studied. Results are discussed in the context of socioanalytic theory and recent theories of self-presentation, affectivity, and the relationship between illusions and well-being.     

Concern for appropriateness as a moderator variable in the statistical explanation of self-reported use of alcohol and marijuana

Two studies examine the Concern for Appropriateness Scale (Lennox & Wolfe, 1984) as a likely moderator of dispositional and environmental variables associated with self-reported use of alcohol and marijuana by college and precollege students. In Study 1, data from 408 upper division students show that concern score interacts significantly with religiosity in analyses of use of both drugs, but not with any of 11 other dispositional variables nor with drug-specific environment predictors in analyses of use of either drug. In Study 2, data from 242 recent high school graduates show that concern score interacts significantly with religiosity and drug-specific environment in the explanation of alcohol use but not in the explanation of marijuana use. All of the significant interactions are in the predicted direction. Results therefore suggest that the concern scale is valid for some of its intended purposes.     

Construct validity of the Concern For Appropriateness scale

Construct validity of the Concern For Appropriateness scale (CFA; Lennox & Wolfe, 1984), a measure of the tendency to adopt protective self-presentation styles, is examined using a multitrait-multimethod approach. Self-ratings on the CFA and ratings by suitemates constitute the two methods, and concern for appropriateness, interpersonal trust, and boredom susceptibility are assessed with each. Multitrait-multimethod analysis shows that the CFA scale exhibits convergent validity against peer ratings and discriminant validity against boredom susceptibility, the only other variable demonstrating convergence. Results indicate that the CFA exhibits construct validity and might therefore prove useful as an operationalization for self-presentation tendencies.     

The Eschatological Turn in German Philosophy

This article argues that modern European philosophy was significantly shaped by the transposition of eschatology from a theological into a philosophical register. By ‘eschatology’, I here mean thought about the ‘last things’ as they relate to present systems of life and action; and about those systems as determined, at least in part, by their end. I take as my starting point the claim that the scepticism regarding revelation that was such a central characteristic of the Enlightenment did not eradicate the importance of eschatology as a structuring frame of historical and moral thought, but merely changed it. Modern theologians and philosophers tended to shift the ground of eschatology from revelation to the inner logic of a system; eschatology was seen as legitimated by, and in turn legitimating, the shape of a given philosophical account of history. The questions and challenges arising from this shift were important drivers of early twentieth‐century European philosophy. This article works out this claim through indicative accounts of several large debates of early twentieth‐century philosophies of history and of politics as contestations about the meaning of eschatology: the crisis of historicism, the rise of existentialism, and the surge of political religions. It concludes with a discussion of Martin Heidegger’s eschatological thought of the 1930s, illuminated by the recent publication of his Black Notebooks.     

Visual search asymmetries in motion and optic flow fields

In visual search, items defined by a unique feature are found easily and efficiently. Search for a moving target among stationary distractors is one such efficient search. Search for a stationary target among moving distractors is markedly more difficult. In the experiments reported here, we confirm this finding and further show that searches for a stationary target within a structured flow field are more efficient than searches for stationary targets among distractors moving in random directions. The structured motion fields tested included uniform direction of motion, a radial flow field simulating observer forward motion, and a deformation flow field inconsistent with observer motion. The results using optic flow stimuli were not significantly different from the results obtained with other structured fields of distractors. The results suggest that the local properties of the flow fields rather than global optic flow properties are important for determining the efficiency of search for a stationary target.
