Enriched Vs Impoverished Housing: Food Choice And Consumption, Berenice Martinez
Enriched Vs Impoverished Housing: Food Choice And Consumption, Berenice Martinez
Theses and Dissertations - UTB/UTPA
This study focused on the relationship between environmental setting, eating choices and food intake. Ten Swiss Webster female subjects were socially housed under impoverished environmental conditions and ten under enriched housing conditions. Subjects were exposed to a nutritious food and sweet fat-laden food diet together with ad lib access to regular tap water on a 12 h light and dark cycle for four weeks. Results showed that an impoverished environment does not lead to an increase in body weight (t(6)= 0.293, p > .05) and environmental manipulations do not delineate a preference for diet type (t(6)= .877, p >.05). Further research …
The Effects Of Physical Activity On Self-Injurious Behavior, Lynnette D. Aguilar
The Effects Of Physical Activity On Self-Injurious Behavior, Lynnette D. Aguilar
Theses and Dissertations - UTB/UTPA
Auto-mutilation is a maladaptive coping mechanism and a major problem confronting behavioral medicine with no known treatment to date to place the behavior on complete extinction. The purpose of this experiment is to examine the possible beneficial effects of running relative to caffeine-induced SIB. Female Sprague Dawley rats (n = 4) served as subjects with each having a different extended baseline and treatment condition. Visual analysis of a multiple baseline graph did not support the hypothesis that as treatment (physical activity) was implemented SIB would decrease. It was found that subjects who drank more caffeinated water had higher amounts of …
The Use Of Debit Cards In Promoting On-Time Payment Behavior In A Daycare Center In The Rio Grande Valley Region Of Texas, Ruben James Nieto
The Use Of Debit Cards In Promoting On-Time Payment Behavior In A Daycare Center In The Rio Grande Valley Region Of Texas, Ruben James Nieto
Theses and Dissertations - UTB/UTPA
The study investigates the inappropriate payment behavior of consumers at a local daycare in the Rio Grande Valley. An AB, baseline and intervention, single subject design was used to increase the on-time payment behavior of consumers paying on time at the daycare. Baseline data was taken for 14 weeks before the intervention was implemented. The intervention consisted of an alternative payment method, accepting credit and debit cards, [as an antecedent, to the consumer in order to receive payments on time]. This alternative payment method showed that on-time payment behavior increased compared to pre-intervention.
Does Responding On Progressive Ratio Schedule Of Reinforcement Vary As A Function Of Phase In Estrous Cycle?, Armandina M. Sanchez
Does Responding On Progressive Ratio Schedule Of Reinforcement Vary As A Function Of Phase In Estrous Cycle?, Armandina M. Sanchez
Theses and Dissertations - UTB/UTPA
Hormonal fluctuations across the menstrual and estrous cycle have been found to influence a variety of behavioral and physical responses in humans and animals, respectively. Impulsive behavior has been associated with the luteal phase of the cycle. Progressive ratio schedule of reinforcement has been widely used to assess the strength of reinforcers. In the present study, a comparison was made between the rate of motor activity, lever pressing, of early and late estrous groups. Differences between the groups were not statistically significant. Further analysis explored subjects individually. Visual examination of the data reveal extreme variability in responding, which coupled with …
Are Progressive Ratio And Fixed Interval Schedules Of Reinforcement Related Measures Of Impulsivity?, Christine Guiterrez
Are Progressive Ratio And Fixed Interval Schedules Of Reinforcement Related Measures Of Impulsivity?, Christine Guiterrez
Theses and Dissertations - UTB/UTPA
The area of impulsivity is widely studied among many different professional fields. However, given the broad brush that has been used to paint the construct of impulsivity, it’s apparent that there is no true agreement on a definitive definition. In the present study, a purely behavioral procedure was tested with 10 female Sprague-Dawley rats who were placed on a progressive ratio and then a fixed interval 20 s schedule of reinforcement to see if these two schedules were related measures of impulsivity. The definition of impulsivity used in this study was relative to the performance of all animals in that …
