Activity Measures

62 rats, operationally divided into those who were seizure-prone and nonseizure-prone, gave similar activity measures over the shorter delays of test but seizure Ss in the longer delay groups moved less than nonseizure Ss before and after bell-can treatment. This finding was interpreted as evidence for an interaction between seizure-prone condition with longer periods of fasting. When Ss were tested in a 4-manipulandum test situation, reinforcement schedules (CRF, FR-4, VR-4, and controls) were differentially effective. Preferences for specific devices developed. Response variability did not differentiate seizure and nonseizure Ss but was significantly influenced by schedules of reinforcement.

Odour Perception

Data previously collected to determine odour thresholds in fish flesh for individual contaminants identified as possible fish tainting substances from oil sands wastewaters were reanalyzed to determine both the variability in response for an 11 member panel and the range of uncertainty for the detection method. Results are presented for 8 compounds: naphthalene, 1-methylnaphthalene, 2,6-dimethylnaphthalene, 2,3,5-trimethylnaphthalene, 1.4-dimethylbenzene, benzothiophene, dibenzothiophene and 2,5-dimethylphenol. These results demonstrate that substantial variability was present in responses from a group of only 11 panelists who were selected for their sensitivity and consistency, while method uncertainty was tolerably narrow.
