An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler
An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler
Dissertations
Approval does not function as a powerful reinforcer for many children with autism, making it difficult to reinforce appropriate behavior in a functional and consistent manner. The current study first assessed the effects of establishing approval (“Nice,” accompanied by a smile and nod) and nonsense words as discriminative stimuli, with the intent that they might also become learned reinforcers. We conducted several experiments to assess the effectiveness of approval as a reinforcer, including tests on learning new responses (receptive, expressive, freeoperant, and simple simultaneous discriminations) and tests on the performance of previously mastered responses (receptive and expressive responses). Despite the …
The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker
The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker
Masters Theses
In recent years, researchers have evaluated individuals' preferences for different mand modalities and its effects on the acquisition of novel mands during functional con1munication training (i.e., FCT; e.g., Falcomata, Ringdahl, Christensen, & Boelter, 20 I 0). In many of these studies, the modality of responding that Michael ( 1985) classified as selection-based responding, is preferred by participants (e.g., Falcomata et al., 201 0). Wraikat, Sundberg, and Michael (1991) suggest that topography-based responses may be preferable for the acquisition of complex language. However, selection-based verbal responses may have faster acquisition in learning initial verbal operants (Charlop-Christy, Carpenter, Le, LeBlanc & Kellet, …
Combined Effects Of Mdma And Ethanol On Locomotor Activity And Place Conditioning In Male And Female Adolescent Sprague-Dawley Rats, Keli A. Herr
Masters Theses
MDMA, ("Ecstasy") is commonly abused in combination with ethanol (EtOH). Relatively few preclinical studies have investigated sex differences in animal models of polysubstance use. The current study employed a conditioned place preference (CPP) procedure to assess the behavioral effects of the co-administration ofMDMA /EtOH in 32 male and 32 female adolescent Sprague-Dawley rats. Following a 15 min habituation trial, eight 30-min conditioning trials were conducted in two- compartment chambers with different environmental cues. Before each drug conditioning trials, rats were administered intraperitoneal (i.p.) injections of MDMA(6.6 mg/kg), EtOH (1.5 g/kg), MDMA (6.6 mg/kg) and EtOH (1.5 g/kg), or saline. Prior …
The Gender Of Participants In Published Research Involving People With Autism Spectrum Disorders, Erin Watkins
The Gender Of Participants In Published Research Involving People With Autism Spectrum Disorders, Erin Watkins
Masters Theses
Research articles involving participants with an autism spectrum disorder and published from 2010-2012 in Autism, Journal of Autism and Developmental Disorders, Journal of Child Psychology and Child Psychiatry, and Research in Autism Spectrum Disorders were examined to determine the reported gender of participants. The overall male:female ratio was 4.62, which is similar to that reported in epidemiological studies, but the ratio was 6.07 in intervention studies. These findings suggesting that males were in a statistical sense over-represented in intervention studies, but not in other kinds of research. Most (82.21%) of these studies included both male and female participants, but …
