Presents a model that borrows concepts of economic utility theory to describe the effects on behavior of a contingency among responses. If subjects allocate their time among responses to maximize the value of their behavior, contingency may be seen to restrict the set of available allocations. Describes the allocation of time to contingent,…

Describes an algorithm used at the University of Ottawa to create examination schedules that are not only conflict free and minimize number of consecutive examinations for individual students, but provide for the scheduling of certain proper subsets of examinations into proper time slots and minimal overall number of consecutive examinations.

Tested 3-, 5-, and 8-year-olds on temporal generalization with visual stimuli. Found increasing sharpness of generalization gradient with increasing age, and change from symmetrical to adult-like asymmetrical generalization gradients among 8-year-olds. Theoretical models attributed changes to increasing precision of the reference memory with…

The present experiments extend the temporal discounting paradigm from choice between an immediate and a delayed reward to choice between 2 delayed rewards: a smaller amount of money available sooner and a larger amount available later. Across different amounts and delays, the data were consistently well described by a hyperbola-like discounting…

The author lists the advantages of component models and suggest their substitution for sequence models, which emphasize time rather than space relationships, in the teaching of geomorphology. (JH)

National policy makers have put forth different life cycle planning proposals for the more satisfying integration of education, work and leisure over the life course. This speech describes a decision making scheme, the Time Paradigm, for researched-based choice among various proposals. The scheme is defined in terms of a typology of time-related…

Examines the temporal reference of Spanish verb forms by using a simple time axis showing five points of temporal reference. (NCR)

This paper is a study of textbooks in chemical technology in Sweden during the industrialisation in the 19th century. In this period, teaching in technological education in general became more and more founded on science. However, there existed very few textbooks in chemical technology, and it is argued that the reason was that the essentials of…

A typology of time-related concepts is put forth as a step toward the building of comprehensive theory in aging. The concepts derive from statistics (age, cohort, period effects), the theoretical writings of Sorokin (life course role sequences, durations and rates), the writings of Riley (on the synchronization of life course socialization and…

Proposes an account of the development of temporal understanding, linking it with episodic memory development. Distinguishes between ways of representing time in terms of frameworks involved; describes perspectival and nonperspectival frameworks and those representing recurrent sequences or particular times. Describes emergence of new kinds of…

Paper has attempted to display two sets of perceptual disorganizations, both parents' and children's. As well, suggestions for action are given. (Author/RK)

Examined developmental changes in time estimation among 5- to 99-year olds. Found that older adults and young children performed at lower levels than young adults; identified qualitative differences in error patterns of older adults and children. Proposed model of temporal generalization and bisection assuming developmental changes in noisiness of…

In this article the five career narratives of three siblings and two unemployed men are drawn upon to critically examine the use of contemporary career discourse as a means to negotiate changes to work since the 1980s and to the present time. A critical analysis enables contemporary career discourse and workplace change to be located within the…

Presents to subjects graphs representing differential variabilities over time in an attitude, a behavior, and a physical state and asks them to estimate the possibility of influencing each trend. Highly variable attitudes were seen as susceptible to change, whereas the others were not. (RW)

Observed changes in clients' expectations-perceptions over time and as a function of duration in counseling, and the relationship between perceptions and actual interview behavior. Results suggested before counseling clients focused more on the relationship than on expected results. By termination, perceptions of process and outcome were similar.…
