An 8-step program: Shaping and fixed-time food delivery effects on several approximations and undesired responses in goats.

An 8-step program: Shaping and fixed-time food delivery effects on several approximations and undesired responses in goats.

Date: May 2003
Creator: Fernandez, Eduardo J.
Description: This study investigated the effects of a shaping program for halter training across 8 steps in the program and 4 trial-terminating, or "undesirable," responses. Three La Mancha goats (Capra hircus) located at the Frank Buck Zoo in Gainesville, Texas were used for the study. A fixed-time 15 s (FT-15 s) was used during the baseline conditions, to examine the effects of response contingent and response-independent food deliveries, as well as to examine what preliminary steps might not necessarily have to be shaped. All 3 goats successfully learned to allow the halter to be placed on them and to lead on the halter, although 2 of the 3 goats required an additional task analysis for the fifth step to further break down that approximation. Several of the early steps selected by the researchers were not necessary to complete the program, as determined by the baseline condition.

Adolescent goals and their reports of what they do to achieve those Goals

Adolescent goals and their reports of what they do to achieve those Goals

Date: May 2000
Creator: Lucky, Derek
Description: Twenty-five adolescents' ranking of a set of equally highly valued goals on a Paired-comparisons Survey was compared with what adolescents say they are doing to achieve those goals. Results of the Paired-comparisons Survey showed that adolescents ranked career, interpersonal, and educational goals rather high and reputation and self-presentation goals rather low. Results analyzed with a contingency coefficient and biserial correlation indicated that not all number one ranked goals had the same value for a particular adolescent, and that number one ranked goals were correlated with verbal reports of concrete actions directed at achieving those goals.

An analysis of sample duration in a parent training program.

An analysis of sample duration in a parent training program.

Date: May 2007
Creator: Laino, Kathleen S.
Description: Although several guidelines are available for designing observational procedures in both basic and applied settings, few researchers have experimentally examined and compared different direct observation methods. Such methods may have a direct impact on practitioners' ability to effectively assess strengths and challenges, set treatment goals, adjust intervention procedures, and monitor progress. The current study compared 1 and 5 min observations to 10 min observations throughout baseline and intervention phases of a parent training program for toddlers with autism. Results showed similarities with regards to variability, level, and trend in the 5 and 10 min data samples; however, clear differences were seen in the 1 min data sample, which typically showed very low occurrences of responding and displayed steady and flat trends. The findings have implications for the development of time-efficient direct observation procedures utilized in parent training programs for children with autism.

Analyzing the Effects of a Performance Pay Plan on Manager Performance in an Accounting Firm

Analyzing the Effects of a Performance Pay Plan on Manager Performance in an Accounting Firm

Date: May 2007
Creator: McDaniel, Sarah Curran
Description: This study examined the effect of a score card¬-based performance pay plan in a professional services firm. The plan was implemented in response to a decreasing trend in productivity and a desire for a formal incentive compensation plan. Performance of manager and senior manager accountants were analyzed across two departments over a five year period. A definitive account of the effects of the intervention is limited by the case-¬study design, but the data does suggest that the performance pay plans used did not adversely affect performances. Design limitations of the plan and future research are also discussed.

Assessing optimal sibling training conditions: An empirical approach.

Assessing optimal sibling training conditions: An empirical approach.

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: Merker, Stephanie K.
Description: The purpose of the study was to investigate the effects of play materials on the interactions between a child with autism and her sibling. Three conditions were assessed: open choice, materials chosen by the child with autism, and materials chosen by the typically developing sibling. Within each activity, measures of social interactions were assessed. Results of the assessment showed that more interactions occurred with a material chosen by the child with autism. After sibling training (targeting specific teaching skills), social interactions remained highest in the condition with materials chosen by the child with autism. The results are discussed in terms of a material assessment to optimize sibling training conditions and the importance of sibling relationships.

Assessing play interests in toddlers.

Assessing play interests in toddlers.

Date: December 2009
Creator: Kodaka, Mitsuru
Description: Play is a significant part of childhood. Typically developing children exhibit a wide range of interests within their play behavior, but children with autism do not. The purpose of this study was to design and implement an assessment tool that will capture the constellation of behaviors indicating play interests in young children. The Early Play Interests Assessment (EPIA) includes categories of play behavior and their components behaviors. Additionally, measures of child affect were built into the EPIA. All behaviors were observed under various environmental conditions. The results show that the EPIA was useful in observing toddlers' play behavior within behavioral categories and components and in assessing the interactions among these measures of play interests. The results are discussed in relation to the importance of creating observational systems to quantify play interests in typical and atypical children and for establishing a link between the information gathered in assessment and the planning and implementation of autism interventions.

Assessing the stimulus control of observers.

Assessing the stimulus control of observers.

Date: December 2009
Creator: Kuhn, Robin Merritt
Description: The science of behavior analysis relies heavily on direct observation. Human observers are typically used to measure behavior in applied settings. Although the use of human observers is beneficial in many regards, it also presents challenges. Of primary concern is the extent to which the data generated by observers actually corresponds to the behavioral events of interest, and the implications this may have in terms of replication. This study assessed the effects that labels, definitions, and examples and non-examples of two different modalities had on observer accuracy, consistency, and agreement. Results showed that current practices in observer training may require refinement to ensure high observer accuracy, consistency, and agreement. Suggestions for how to improve the desired stimulus control of observers are provided.

Assessment of Resident and Staff Activity in a State Residential Setting

Assessment of Resident and Staff Activity in a State Residential Setting

Date: December 2003
Creator: Galletta, Katharine Lena
Description: Previous studies have demonstrated the use of momentary time-sampling methods for the objective measurement of naturally occurring events (Zarcone, Iwata, Rodgers & Vollmer, 1993; Shore, Lerman, Smith, Iwata & DeLeon, 1995). These studies have provided information about observed levels and characteristics of direct care services, supervision, resident activity and facility conditions. The present study evaluated the utility of these assessment procedures in a residential facility for developmentally delayed adults. The procedure was further evaluated for sensitivity to changes relative to an intervention designed to increase staff and client interaction. A multiple baseline design was used to assess a data collection procedure in the context of intervention in four residences on a state facility campus. Intervention included the use of scheduling, modeling and performance feedback. Results indicate an overall increase of staff and client interaction and demonstrate the utility of the assessment procedure for the evaluation of multiple, on-going activities as well as intervention effects.

An attempt to dissociate effects of response requirements and sample duration in conditional discrimination learning with pigeons.

An attempt to dissociate effects of response requirements and sample duration in conditional discrimination learning with pigeons.

Date: May 2009
Creator: Levine, Joshua
Description: Attempts to control various aspects of response requirements and sample viewing durations of sample stimuli show that an increase in both facilitates acquisition of conditional discriminations. Despite these attempts, few empirical data exist that demonstrate the relative contributions of both response- and time-dependent schedules. In addition, viewing opportunities of sample stimuli are present outside of the researchers' control, allowing for 'unauthorized sample viewing.' This study employed a titrating delay matching-to-sample procedure to systematically control various aspects of response requirements and sample viewing durations to independently assess their relative contributions towards conditional discrimination performance. Four pigeons worked on a titrating delay matching-to-sample procedure in which the delay between sample offset and comparison onset continuously adjusted as a function of the accuracy of the pigeons' choices. Results show sample viewing durations contribute most toward conditional discrimination performance. The data show 'unauthorized sample viewing' improved acquisition of conditional discriminations and should be a consideration in design of future research.

A behavioral economic analysis of different reinforcers: Sound-clips versus points exchangeable for money

A behavioral economic analysis of different reinforcers: Sound-clips versus points exchangeable for money

Date: December 2000
Creator: Alvey, Debi A.
Description: Human operant studies frequently use points exchangeable for money as reinforcers. Some studies employ more immediately consumable reinforcers to emulate properties of food reinforcers. This study examined demand for points/money and for sound-clips to compare their economic characteristics. Across four participants, demand was often higher and less elastic for points/money than for sounds. During subsequent exposures at each response requirement, demand for sounds often decreased to a greater degree than demand for points/money. Thus, sound-clips seem less durable than points/money across prices and across repeated exposure to the same price. Response rates for points/money were often higher than for sounds, suggesting that reinforcers that generate higher response rates may be less elastic than reinforcers that generate lower response rates.
