• 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 ...

  

• The relative effectiveness of alternative treatments for young children with attention deficit hyperactivity disorder 

  Heriot, S.A. (The University of Waikato, 1999)

  The objective of this study was to evaluate the relative effectiveness of pharmacological and behavioural interventions for young children diagnosed with Attention Deficit Hyperactivity Disorder. A randomised between-groups ...

  

• Concurrent schedule performance of possums: a comparison of two models 

  Bron, Angela (The University of Waikato, 2001)

  These experiments examined the behaviour of brushtail possums (Trichosurus vulpecula) under concurrent variable-interval schedules of reinforcement. In the first experiment the lever pressing of six possums resulted in ...

  

• Assessing psychophysical abilities in brushtail possums. 

  Signal, Tania Dawn (The University of Waikato, 2002)

  In Experiment 1, 6 brushtail possums were trained, using food, to perform a conditional discrimination between flickering (5.00 Hz) and steady lights. A block-wise method of limits procedure was then used to increase flicker ...

  

• The utility of the psychopathy checklist- screening version for predicting serious violent recidivism in a New Zealand offender sample 

  Wilson, Nicol John (The University of Waikato, 2003)

  This study set out to evaluate the ability of the Psychopathy Checklist: Screening Version (PCL: SV) to predict criminal reoffending by New Zealand offenders convicted of previous serious violent offences. Psychopathy has ...

  

• Effects of sample-set size on delayed-matching-to-sample 

  Adamson, Coreen (The University of Waikato, 2002)

  In a series of experiments the discriminative performance of university students was assessed using a Delayed-Matching-to-Sample task. White disks, presented on computer screens, served as stimuli. For the general DMTS ...
