Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist
Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist
Dissertations
Recent escalation in the popularity of recreational synthetic cathinone (“bath salts”) use has prompted numerous scientific investigations of the neurochemical and behavioral effects of 3,4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC), two of the more common chemical constituents of these illicit “bath salts”. Previous neurochemical and electrophysiological studies have revealed that MDPV functions as a blocker, and 4-MMC as a substrate, at monoamine transporters, and both produce transient increases in extracellular monoamines. In addition, previous research has demonstrated that MDPV and 4-MMC support self-administration in nonhuman experimental subjects, and their rewarding effects are observed when paired with contextual cues in nonhuman models …
Increasing Vocal Behavior And Establishing Echoic Stimulus Control In Children With Autism, Joseph Shane
Increasing Vocal Behavior And Establishing Echoic Stimulus Control In Children With Autism, Joseph Shane
Dissertations
Many children with autism fail to demonstrate vocal-verbal behavior, including echoic behavior, as early as their typically developing peers. Some also make very limited vocal sounds in general, remaining mostly mute aside from crying or engaging in stereotypy. Echoic behavior involves auditory discrimination and matching, and functions as a beneficial, if not necessary, prerequisite for many other vocal-verbal skills. The purpose of this study was to develop and implement an echoic training procedure for primarily non-vocal children who did not demonstrate auditory discrimination in baseline. The intervention consisted initially of sessions in which any vocal sounds were reinforced. Then differential …

Session-By-Session Feedback From Psychotherapy Outcome Assessment: An Analysis Of Treatment Utility, Lynn Hallberg Hall
Dissertations
This study sought to examine the effect of providing outcome assessment data to therapists treating a sample of community adults seeking mental health services at two university training clinics. The participants (N = 41) were predominantly unmarried, Caucasian females, 19 to 39 years old, with a wide range of psychological problems. The therapists were trainees from master’s and doctoral programs in counseling and clinical psychology participating in their first clinical practicums. The Outcome Questionnaire 45-2 (OQ), an instrument designed for frequent measurement of client symptom, interpersonal, and social-role distress, served as the dependent measure. The OQ was designed to show …
