In a discrete-trial conditional discrimination procedure, 4 pigeons obtained food reinforcers by pecking a key with a short latency on trials signaled by one stimulus and by pecking the same key with a long latency on trials signaled by a second stimulus. The physical difference between the two stimuli and the temporal separation between the latency values(More)
A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract Parallel software development must face the fact that diierent ar-chitectures require diierent implementations. Flexibility in modifying parallel methods and software is necessary because the eeciency of algorithms is dependent on the characteristics of the(More)
Domain decomposition is a well known technique in parallel computing. It requires the decomposition of a problem domain into sub-domains. This involves also a decomposition of the data structures for the problem into substructures, one for each sub-domain. If the data structures are complex, then the decomposition of the data structures may be a complicated(More)
Preferences of hungry pigeons among 10 grains and pellets were analyzed using a Thurstone scaling procedure. The recovered scales were positively correlated with size of the feed. The correlations improved when the Thurstonian assumption of equal-sized discriminal dispersions (Case V) was replaced with the assumption of proportional-sized dispersions (Case(More)
In this paper, a short overview of project 3 "Advanced Flux Modelling" in the NOWESP project of the MAST II programme is given. The computational requirements of large scale 3-D ow and transport models of the NorthWest European Shelf are considered. The possibilities and implications of massively parallel processors for the simulation of these models are(More)
We propose that a fundamental unit of behavior is the concurrent discriminated operant, and we discuss in detail a quantitative model of the concurrent three-term contingency that is based on the notion that an animal's behavior is controlled to differing extents by both stimulus–behavior and behavior–reinforcer relations. We show how this model can(More)
