A Systematic Review Of The Literature On The Assessments Used For Social Communication In The Diagnosis Of Autism Spectrum Disorder, Rachel E. Kim
A Systematic Review Of The Literature On The Assessments Used For Social Communication In The Diagnosis Of Autism Spectrum Disorder, Rachel E. Kim
Masters Theses
This review of the literature aims to analyze the current assessments available for clinicians, parents, and other professionals to use during the diagnosis of Autism Spectrum Disorder (ASD) that specifically addresses social communication. Although ASD can be diagnosed as early as the age of 2, children are often not diagnosed until the age of 4-5 years old. Especially for children who would be diagnosed with ASD and require Level 2 and/or Level 3 supports, early diagnosis can lead to early intervention which can help to provide the necessary support for both the child and family. Early intervention can help to …
A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla
A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla
Masters Theses
Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify …
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 …
Delayed Match-To-Sample In Preschool Children, Thomas Ratkos
Delayed Match-To-Sample In Preschool Children, Thomas Ratkos
Masters Theses
In delayed match-to-sample (DMTS) tasks, a sample stimulus is shown and then removed for some period of time before comparison stimuli are presented. Joint control theory (Lowenkron, 1984, 1988, 1991, 1998, 2006) explains correct selections on delayed match-to-sample tasks in terms of the joint control of behavior by the comparison stimulus and a repeated word or words originating from the sample stimulus. Eight children ages 3 to 6 were exposed to a DMTS task with visual stimuli using a 15s delay. During training, children were taught to name the stimulus cards and then repeat the name of the target stimulus …
Schedule Thinning Following Mand Training: Attempts To Enhance Signaled Delay To Reinforcement, Jamie M. Severtson
Schedule Thinning Following Mand Training: Attempts To Enhance Signaled Delay To Reinforcement, Jamie M. Severtson
Masters Theses
Mand training, a common component of language training programs for children with autism, is associated with several clinical benefits (Sundberg & Michael, 2001), yet mand training sometimes results in high-rate responding that is difficult to maintain. One method of reducing high-rate mands to manageable rates is known as graduated signaled delay to reinforcement. The current investigation involved a series of three studies to evaluate the ability of three independent variables (a) highly preferred toys, (b) signal duration, and (c) schedule thinning methods to enhance signaled delay to reinforcement. The results of the three studies indicate that 7 of the 8 …
