Comparing Indices of Happiness during Teaching Interactions

Comparing Indices of Happiness during Teaching Interactions

Date: May 2010
Creator: Anderson, Claire Therese
Description: The measurement of happiness has received increasing attention in behavior analytic literature. Happiness in individuals with developmental disabilities has been assessed by 1) counting a specific behavior, or 2) sampling constellations of behaviors. The purpose of this study was to examine the two approaches while observing nine child and teacher dyads at an autism treatment center. Results showed that, overall, a constellation of behaviors can yield similar patterns when compared to a specific behavior count. However, the affect of one person did not predict the affect of the other and similar instructional conditions did not predict affect either. The implications of these results and future directions are discussed.

Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism

Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism

Date: 2016-5
Creator: Litvin, Melanie Ann
Description: Reinforcer assessments have largely relied on the use of progressive ratio (PR) schedules to identify stimuli that function as reinforcers. PR schedules evaluate the reinforcing efficacy of a stimulus by measuring the number of responses produced in order to access a stimulus as the number of required responses increases. The current evaluation extends the literature on reinforcer assessments by measuring responding under a progressive force (PF) schedule, in addition to progressive ratio requirements. We compared responding under PR and PF schedules with two children with autism using a multielement design embedded within a reversal experimental design. Results were mixed and implications for further development of reinforcer assessment methods (particularly PF schedules) are discussed.

A Comparison of Auditory and Visual Stimuli in a Delayed Matching to Sample Procedure with Adult Humans.

A Comparison of Auditory and Visual Stimuli in a Delayed Matching to Sample Procedure with Adult Humans.

Date: December 2002
Creator: DeFulio, Anthony L.
Description: Five humans were exposed to a matching to sample task in which the delay (range = 0 to 32 seconds) between sample stimulus offset and comparison onset was manipulated across conditions. Auditory stimuli (1” tone) and arbitrary symbols served as sample stimuli for three (S1, S2, S3) and two (S4 and S5) subjects, respectively. Uppercase English letters (S, M, and N) served as comparison stimuli for all subjects. Results show small but systematic effects of the retention interval on accuracy and latency to selection of comparison stimuli. The results fail to show a difference between subjects exposed to auditory and visual sample stimuli. Some reasons for the failure to note a difference are discussed.

A Comparison of Brief Versus Extended Paired-Choice Preference Assessment Outcomes.

A Comparison of Brief Versus Extended Paired-Choice Preference Assessment Outcomes.

Date: December 2005
Creator: Cason, Caroline Adelaide
Description: Few studies have systematically evaluated whether preferences can reliably be identified using brief procedures. Typically, studies have used brief procedures to select potential reinforcers for use in intervention procedures. A total of 17 food and leisure paired-choice preference assessments were administered to 10 subjects in order to evaluate the extent to which the results of a brief (i.e., single-session) assessment correspond with those from more extended procedures (i.e., 5 sessions). Eleven out of the 17 brief and extended assessments identified the same stimulus as the most preferred (highest rank). Outcomes suggest that a brief assessment can be useful when a single, potent reinforcing stimulus is desired, and an extended assessment should be conducted when a larger number of preferred stimuli is desired.

Comparison of Client Attendance, Attrition, and Outcomes in 2 Class System Packages.

Comparison of Client Attendance, Attrition, and Outcomes in 2 Class System Packages.

Date: August 2008
Creator: Berends, Valori
Description: Using the principles of systems analysis as a guide, this study compared two class schedule formats used by Behavior Management and Parenting Services (BMAPS) in order to address the following research questions: 1) What effects do 2 different class formats have on student attrition and appointment keeping? 2) What effects do 2 different class formats have on student outcomes on a pre and posttest assessment? 3) What effects do 2 different class formats have on staff procedures? BMAPS provides parent education to individuals referred by Child Protective Services. The current research included approximately 200 referred clients with an appointment or class scheduled with BMAPS between January 1, 2006 and September 22, 2007. Data was collected by reviewing client files for class attendance and performance records. Results of this study allow BMAPS to enlist the class format that is correlated with better attrition rates and client outcomes.

A Comparison of Discounting Parameters Obtained Through Two Different Adjusting Procedures: Bisection and Up-Down.

A Comparison of Discounting Parameters Obtained Through Two Different Adjusting Procedures: Bisection and Up-Down.

Date: December 2007
Creator: Woelz, Thomas Anatol da Rocha
Description: The study compared delay discounting in adult humans using two different methods of adjustments. Both methods used hypothetical choices of monetary outcomes. One involved adjustments using a fixed sequence of ascending or descending amounts, the other used a bisection algorithm in which the changes in amounts varied as a function of the subjects' choices. Two magnitudes of delayed outcomes were used: $1,000 and $10,000. A within subject design was used to compare indifference curves and discounting measures across the two adjusting procedures. Twenty four subjects were divided in two groups and exposed to the procedures in opposite order, to account for sequence effects. Results from within subject comparisons showed no systematic differences between procedures.

A Comparison of Picture to Word Training and Word to Word Training on Native English Speaking College Students’ Acquisition of Italian Vocabulary

A Comparison of Picture to Word Training and Word to Word Training on Native English Speaking College Students’ Acquisition of Italian Vocabulary

Date: December 2013
Creator: Vo, Phuong Vi
Description: The current study assessed the effects of two teaching stimulus presentations, i.e. picture to word and word to word, used to teach second language vocabulary to college students. It also evaluated the emergence of untaught relations when picture to word and word to word were used separately as a teaching strategy. The findings showed picture to word training resulted in more untaught relations. Several aspects such time allotted for online quizzes, experimental and teaching arrangements and vocabulary complexity were suggested for future research.

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research

Date: August 1999
Creator: Rouse, Susan L.
Description: Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed up with money were the reinforcers, however, high rates of behavior were generated, disrupting the previously established baseline performance. This suggests that while points may be effective in generating high rates of behavior, they may be ineffective in producing sensitive baselines needed to study human operant behavior on schedules of reinforcement.

A Comparison of the Effects of Errorful and Errorless Teaching Methods on the Acquisition, Generalization, and Retention of Letter Sound Discriminations in Young Children.

A Comparison of the Effects of Errorful and Errorless Teaching Methods on the Acquisition, Generalization, and Retention of Letter Sound Discriminations in Young Children.

Date: May 2007
Creator: Doucette, Jessica
Description: The present study compared the effects of an errorless stimulus shaping procedure to an errorful fluency based procedure for teaching difficult letter sound discriminations using a counterbalanced multielement experimental design. For 2 participants, letters fsteai were taught using the errorless procedure and letters bpdvou were taught using the errorful procedure. For the other 2 participants the conditions were reversed. All participants had considerably fewer errors and fewer trials to criterion with the errorless than with the errorful procedure. Tests of retention and generalization indicate that the errorful procedure generalized and was retained at a higher frequency than the errorless procedure. For 3 participants preference for the errorless procedure over the errorful procedure was demonstrated; whereas, the fourth participant demonstrated preference for the errorful procedure.

A Comparison of Transfer of Stimulus Control Or Multiple Control on the Acquisition of Verbal Operants in Young Children with Autism: an Extension

A Comparison of Transfer of Stimulus Control Or Multiple Control on the Acquisition of Verbal Operants in Young Children with Autism: an Extension

Date: August 2012
Creator: Pasat, Irina V.
Description: One language intervention approach for individuals with autism involves teaching one response topography under multiple sources of control and then establishing that response under individual controlling variable. Another approach involves establishing one response topography under singular control and then using that response to establish the response topography under different controlling variables. The study sought to extend previous research by investigating the impact of each approach on the acquisition of verbal responses. Three of the eight participants acquired all target responses for at least one response topography. The results of previous research were not replicated directly and the findings were discussed in terms of preexperimental verbal repertoires and restricted interests.
