  • An analysis of U-Value as a measure of variability

    Kong, Xiuyuan; McEwan, James S.A.; Bizo, Lewis A.; Foster, T. Mary (The Association for Behavior Analysis International (ABAI), 2017)
    The variability in behavior has frequently been assessed using a measure known as the U-value. Of concern in this article were the limits and constraints on U-value as a measure of variability. The relation between the ...
  • Behavior-based assessment of the auditory abilities of brushtail possums

    Osugi, Mizuho; Foster, T. Mary; Temple, William; Poling, Alan (JEAB/Psychology, 2011)
    Brushtail possums (Trichosurus vulpecula) were trained to press a right lever when a tone was presented (a tone-on trial) and a left lever when a tone was not presented (a tone-off trial) to gain access to food. During ...
  • Comparing demand functions when different price manipulations are used: Does unit price help?

    Sumpter, Catherine E.; Temple, William; Foster, T. Mary (Psychonomic Society Inc, 2004)
    Six hens pecked a key (Experiment 1) or pushed a door (Experiment 2) to obtain food reinforcement. In both experiments and as an analogue of price changes, the response requirements were varied in two ways: by increasing ...
  • A comparison of two methods for assessing critical flicker fusion frequency in hens

    Railton, Renee Caron Richards; Foster, T. Mary; Temple, William (Elsevier, 2009)
    This paper compared two general methods for assessing critical fusion frequency in hens (gallus gallus domesticus). The first method was a conditional discrimination procedure with the stimuli presented successively. The ...
  • Concurrent second-order schedules: some effects of variations in response number and duration

    Sealey, Diane M.; Sumpter, Catherine E.; Temple, William; Foster, T. Mary (Society for the Experimental Analysis of Behavior, 2005)
    To examine the effects on concurrent performance of independent manipulations of response-unit duration and number, 6 hens were exposed to concurrent second-order schedules of reinforcement. Each first-order operant unit ...
