Serial Reversal Learning And The Evolution Of Behavioral Flexibility In Three Species Of North American Corvids (Gymnorhinus Cyanocephalus, Nucifraga Columbiana, Aphelocoma Californica), Alan B. Bond, Alan Kamil, Russell P. Balda

In serial reversal learning, subjects learn to respond differentially to 2 stimuli. When the task is fully acquired, reward contingencies are reversed, requiring the subject to relearn the altered associations. This alternation of acquisition and reversal can be repeated many times, and the ability of a species to adapt to this regimen has been considered as an indication of behavioral flexibility. Serial reversal learning of 2-choice discriminations was contrasted in 3 related species of North American corvids: pinyon jays (Gymnorhinus cyanocephalus), which are highly social; Clark’s nutcrackers (Nucifraga columbiana), which are relatively solitary but specialized for spatial memory; and western …

A Critical Examination Of Food Technology, Innovation And Teacher Education : A Technacy Genre Theory Perspective, Angela Frances Turner

Dr Angela Turner

There are many and varied forces that shape food technology curriculum, but two that emerge as significant and of specific interest to this research are the perceptions of food technology education and economic trends that influence food technology. The broad goal was to examine the extent to which food technology in secondary schooling is well placed to meet emerging policy and economic demand for food innovation expertise in the industry. With both the school sector and the professional sector each asserting that their respective perceptions of Food Technology was correct, a method for clarifying and classifying the nature of the …
