Understanding sustainability

Proposed solutions to sustainability often bring different economic sectors into conflict; when a sustainable solution for one sector is non-sustainable for another it creates what we call the dilemma of sustainability. A recent example took place in the Columbia Basin of the Pacific Northwest, involving competing notions of sustainability by fisheries and the energy industry. Taking up some ideas of Eger and Lyotard, we criticize the constructivist approach which treats large ecosystems as constructions and the process of resolving conflicts of sustainability as one solely consisting of negotiations involving the trading off of interests. We propose instead to treat such conflict resolution via a Gadamerian-inspired hermeneutics that sees different economic sectors as having different interpretations of sustainability and that aims at common understanding.     

Place Learning in Virtual Space I: Acquisition, Overshadowing, and Transfer

Three experiments showed that, in virtual space, humans learn to find an invisible target that remains in a fixed location relative to distal cues. Experiment 1 showed that people rapidly learned to locate an invisible target in a computer-generated virtual arena. Participants searched the appropriate place intensely when, on a probe trial, the target was removed. Experiment 2 showed that two groups of participants, one with a visible and one with an invisible target, learned to locate the target in the virtual arena. A probe trial, during which the target was removed, showed that participants from both groups searched the former location of the target in the virtual arena, suggesting the presence of proximal cues did not interfere with place learning. Experiment 3 showed that, following place learning, people directly approach the location of the invisible target from novel start positions. The data were discussed in terms of spatial learning and memory.

Psychometric properties of the Learning-Orientation Grade-Orientation II Scale.

The Learning-Orientation Grade-Orientation Scale of Eison, Pollio, and Milton was administered to 85 college students and analyzed to study the psychometric properties of the instrument. Scale means were consistent with those usually reported. Cronbach coefficients alpha for 5 of the 6 scales ranged from .58 to .70; however, the coefficient alpha for learning-orientation attitude scale was questionably low (.29). Item analyses and factor analyses support the continued use of at least 5 of the 6 scales measured by the inventory.     

Testing a semistochastic variant of the interactive activation model in different word recognition experiments.

A semistochastic variant of the interactive activation (IA) model of context effects in letter perception (McClelland & Rumelhart, 1981) was used to simulate response time distributions and means in different experiments investigating the effects of word frequency, neighborhood size and frequency, and orthographic priming in visual word recognition. The results provide evidence in favor of the connectivity assumption underlying the model but question the necessity of the interactivity assumption for simulating latencies in word recognition tasks. Together with those of a recent study by McClelland (1991), the present results suggest that 10 years after its appearance, the IA model's potential for testing hypotheses about the structure and dynamics of basic phenomena of human information processing in a variety of perceptual and cognitive tasks is not yet fully exploited.     

On the question of self-disclosure by the analyst: error or advance in technique?

The question of self-disclosure by the analyst and its uses in treatment is an issue widely debated today. In this paper, the author reviews this controversial technique from historical and contemporary points of view, delineates several forms of self-disclosure, and, by means of several clinical examples, discusses the effects on the patient and the analytic process of utilizing one or another kind of self-disclosure in these particular situations.     

Adolescents who apparently are invulnerable to drug, alcohol, and nicotine use

As part of a large survey of addictive behavior in high school students, a group of 43 girls and 34 boys was identified who denied any use of drugs, alcohol, or tobacco. These apparently invulnerable adolescents were compared to the rest of the "user" sample on the remaining items of the questionnaire. The invulnerable students reported generally better physical and mental health and academic achievement. They also indicated a significantly lower rate of similar problems in their parents.
