An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler Dec 2014

An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler

Dissertations

Approval does not function as a powerful reinforcer for many children with autism, making it difficult to reinforce appropriate behavior in a functional and consistent manner. The current study first assessed the effects of establishing approval (“Nice,” accompanied by a smile and nod) and nonsense words as discriminative stimuli, with the intent that they might also become learned reinforcers. We conducted several experiments to assess the effectiveness of approval as a reinforcer, including tests on learning new responses (receptive, expressive, freeoperant, and simple simultaneous discriminations) and tests on the performance of previously mastered responses (receptive and expressive responses). Despite the …


The Impact Of Sleep Restriction (Nap Deprivation) On Preschool Children's (Aged 3-5) Emotional Response, Hui-Ya Gail Han Aug 2014

The Impact Of Sleep Restriction (Nap Deprivation) On Preschool Children's (Aged 3-5) Emotional Response, Hui-Ya Gail Han

Dissertations

This study examined the effect of nap restriction on 3- to 5-year-old habitually napping children’s emotional responding. It was predicted that the intensity of emotional stimuli would moderate the relationship between nap restriction and the magnitude of emotional responding. Specifically, following nap restriction, the emotional responses to stronger stimuli would be amplified, while the emotional responses to weaker stimuli would be reduced. Emotional stimuli, were classified into four categories: strong negative, weak negative, weak positive, and strong positive. Facial electromyography was measured to reflect preschoolers’ emotional responses. The results indicated emotional responses to both strong negative and positive stimuli were …


The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker Aug 2014

The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker

Masters Theses

In recent years, researchers have evaluated individuals' preferences for different mand modalities and its effects on the acquisition of novel mands during functional con1munication training (i.e., FCT; e.g., Falcomata, Ringdahl, Christensen, & Boelter, 20 I 0). In many of these studies, the modality of responding that Michael ( 1985) classified as selection-based responding, is preferred by participants (e.g., Falcomata et al., 201 0). Wraikat, Sundberg, and Michael (1991) suggest that topography-based responses may be preferable for the acquisition of complex language. However, selection-based verbal responses may have faster acquisition in learning initial verbal operants (Charlop-Christy, Carpenter, Le, LeBlanc & Kellet, …


Parental Depression And Child Behavior Problems: A Closer Examination, Yangmu Xu Jun 2014

Parental Depression And Child Behavior Problems: A Closer Examination, Yangmu Xu

Loma Linda University Electronic Theses, Dissertations & Projects

Parents of children with autism spectrum disorders (ASD) have higher rates of depressive symptoms, and parental depressive symptoms are strongly associated with problem behaviors in children. However, the direction of effect between parental depression and child behavior problems is unclear. Additionally, the mechanisms through which parental depression contributes to child behavior problems and vice versa are not well understood. The purpose of the present study is to examine the relationship between parental depression and child behavior problems among families of children with ASD; more specifically to investigate as mediating variables that may explain the mechanisms through which parental depression and …


Who Confronts Sexual Prejudice? How Gender And Ideologies Are Related To Heterosexual Allies Challenging Hate Speech, Kelly L. Lemaire Apr 2014

Who Confronts Sexual Prejudice? How Gender And Ideologies Are Related To Heterosexual Allies Challenging Hate Speech, Kelly L. Lemaire

Master's Theses (2009 -)

Sexual prejudice and discrimination are extremely prevalent throughout society and previous research suggests that there are a multitude of negative consequences associated with being the target of this prejudice. One way of reducing prejudice is by confronting the perpetrator; however the majority of previous research examining confrontation has focused on the target's response to racism or sexism. The current study utilized a 10-condition experimental design in order to examine how the gender of the perpetrator, target, and non-target witness of heterosexist prejudice affected the witness' responses. Attitudinal variables and past allied behaviors were also examined in order to determine if …


An Anti-Bullying Intervention For Children With Autism Spectrum Disorder, Catherine Rex Jan 2014

An Anti-Bullying Intervention For Children With Autism Spectrum Disorder, Catherine Rex

CMC Senior Theses

The effects of a video modeling intervention, given to six children with ASD, were evaluated through a multiple-baseline and multiple-probe design across children. The research targeted teaching children with ASD to assertively respond to physical bullying, verbal bullying, and social exclusion, as well as telling one’s mother. In baseline, the participants demonstrated inconsistent to no skills for responding to the bullying in the vignette movies (SAAS) and the generalization probe skits. During intervention the participants watched a video of a person assertively responding to bullying, and were assessed through VM questions and SAAS. Post-intervention the children participated in generalization probe …
