An analysis of U-Value as a measure of variability
(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 ... -
Examination of the Accuracy and Applicability of Information in Popular Books on Dog Training
(Brill Academic publishers, 2017)There is a wealth of popular literature available on dog behavior and training; sourcing reliable and trustworthy advice is important to achieving successful training. The aim of this study was to select five best-selling ... -
Extinction-induced variability in human behavior
(Psychological Record, Southern Illinois University, 2009)Participants earned points by pressing a computer space bar (Experiment 1) or forming rectangles on the screen with the mouse (Experiment 2) under differential-reinforcement-of-low-rate schedules, followed by extinction. ... -
Matching-to-sample and stimulus-pairing-observation procedures in stimulus equivalence: The effects of number of trials and stimulus arrangement
(Southern Illinois University Carbondale, 2013)Studies comparing the effectiveness of the stimulus-pairing-observation and matching-to-sample procedures in facilitating equivalence relations have reported conflicting findings. This study compared the effectiveness of ... -
Perceptual outcomes as reinforcers
(EAHB SIG, http://www.eahb.org/NewSitePages/BulletinHomepage.htm, 2003)The paucity of basic behavioral research with humans was highlighted almost 40 years ago (Findley, 1966). A recent search of the basic behavioral research journals by the present authors indicated that this situation ...

Effects of sample-set size on delayed-matching-to-sample
(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 ... -
The effects of shadow presence on visual object-recognition
(The University of Waikato, 2004)Shadows provide valuable cues for many aspects of visual perception. This thesis discusses the definitions of cast and attached shadows, and the different types of shadow borders that exist. Eight experiments investigated ... -
An investigation into the persistence-strengthening effects of differential reinforcement of alternative (DRA) behaviour
(The University of Waikato, 2018)Ten experiments used hens to investigate the effects of different disruptive events and ways of introducing differential reinforcement of alternative behaviour (DRA), on the persistence of responding. Of interest was the ... -
To work or not to work: The effect of response requirement variation on signal detection performance in hens
(The University of Waikato, 2017)The role of effort in an SDT paradigm has not been adequately investigated using only natural contingencies, where hits are the only reinforced responses. Fixed-ratio (FR) requirement as a measure of effort was systematically ... -
Differential Reinforcement of Low-Rate Behaviour In The Brush Tail Possum Explicit Alternative Responses During Differential Reinforcement of Low-Rate Responding
(The University of Waikato, 2017)Differential reinforcement of low rate responding (DRL) can be defined as withholding reinforcement until probability of a target behaviour has decreased to a particular criterion. Typically, the DRL lowers the overall ...
