| Abstract: Clinicians regularly use preference and reinforcer assessments to identify effective reinforcers. Typically measurement of stimuli occurs subsequent to the assessment of preferences to confirm putative reinforcers. The types of preference assessment and tests of reinforcing efficacy used vary widely and usually to take into account ecological fit. Consideration of the assessment and measurement of effects of different types of stimuli must be taken. This symposium includes four presentations that report on multiple types of methods to assess preference and measure the effects of reinforcers, which advance methods in preference assessment and reinforcer measurement . Two studies involved the use of video-based stimuli to assess preference in paired-choice and multiple stimulus without replacement preference assessments. One study compared two different types of preference assessments (i.e, . multiple stimulus without replacement and response restriction). In two studies researchers examined the reinforcing effects using a progressive-ratio schedule, while in a different study researchers |

Examining Factors Related to Animal-Assisted Intervention for Children With Autism Spectrum Disorder: Evaluation of Video-Based Preference Assessment and Validation |

| Abstract: Recent research suggests benefits of the presence of pets in social responding of children with ASD. It follows, pets may be preferred and valuable as rewards in treatments for these children. However, preference for animals, and contingent access to animals to increase desired responding has not been clearly demonstrated in research. This study aimed to investigate preference for, and rewarding efficacy of a typical animal pet (i.e., dog) in children with ASD. We conducted in vivo and video-based paired-preference assessments including a dog. We subsequently conducted reinforcer assessments using progressive ratio schedules. Results of this study revealed in vivo and video-based preference assessment outcomes highly correlated for 2 of 3 participants. Outcomes of reinforcer assessment revealed access to a dog served as a reinforcer. However, relative reinforcing efficacy of the dog was not as strong as other social interactions for 1 of 3 participants. |

| Abstract: Brief and continuous conditioned reinforcers have been shown to have differential effects on free operant responding in basic literature (Findley and Brady, 1965; Jwaideh, 1973). Specifically, brief conditioned reinforcers have been demonstrated to have a response optimizing effect when delivered contingent on responding under second-order schedules of reinforcement (Findley and Brady, 1965; Malagodi, DeWesse, and Johnston, 1973). Alternatively, continuously present stimuli that are associated with the initial components of second-order tokens schedules of reinforcement have been shown to result in response suppression under specific schedule parameters (Foster, Hackenberg, and Vaidya, 2001; Bullock and Hackenberg, 2006). Although these types of conditioned reinforcers are used extensively in applied settings, there has been limited applied research on the effect these stimuli may differentially have on the behavior of humans (Kazdin & Bootzin, 1972; Hackenberg 2018). The purpose of the present study is to determine whether these types of conditioned reinforcers have differential effects on the behavior of humans. Preliminary results show that these stimuli produce differential effects on the amount of behavior maintained under progressive ratio schedules of reinforcement with continuous second-order schedules of reinforcement maintaining the highest response counts relative to brief and tandem second-order schedules. |
