Country Roads, Take Me Home ... To My Friends: How Intelligence, Population Density, And Friendship Affect Modern Happiness, Norman P. Li, Satoshi Kanazawa Nov 2016

Country Roads, Take Me Home ... To My Friends: How Intelligence, Population Density, And Friendship Affect Modern Happiness, Norman P. Li, Satoshi Kanazawa

Research Collection School of Social Sciences

We propose the savanna theory of happiness, which suggests that it is not only the current consequences of a given situation but also its ancestral consequences that affect individuals’ life satisfaction and explains why such influences of ancestral consequences might interact with intelligence. We choose two varied factors that characterize basic differences between ancestral and modern life – population density and frequency of socialization with friends – as empirical test cases. As predicted by the theory, population density is negatively, and frequency of socialization with friends is positively, associated with life satisfaction. More importantly, the main associations of life satisfaction …


Blame The Shepherd Not The Sheep: Imitating Higher-Ranking Transgressors Mitigates Punishment For Unethical Behavior, Christopher W. Bauman, Leigh Plunkett Tost, Ong, Madeline Nov 2016

Blame The Shepherd Not The Sheep: Imitating Higher-Ranking Transgressors Mitigates Punishment For Unethical Behavior, Christopher W. Bauman, Leigh Plunkett Tost, Ong, Madeline

Research Collection Lee Kong Chian School Of Business

Do bad role models exonerate others’ unethical behavior? Based on social learning theory and psychologicaltheories of blame, we predicted that unethical behavior by higher-ranking individuals changes howpeople respond to lower-ranking individuals who subsequently commit the same transgression. Fivestudies explored when and why this rank-dependent imitation effect occurs. Across all five studies, wefound that people were less punitive when low-ranking transgressors imitated high-ranking membersof their organization. However, imitation only reduced punishment when the two transgressors werefrom the same organization (Study 2), when the transgressions were highly similar (Study 3), and whenit was unclear whether the initial transgressor was punished (Study 5). …


Parasite Stress And Pathogen Avoidance Relate To Distinct Dimensions Of Political Ideology Across 30 Nations, J.M. Tybur, Y. Inbar, L. Aaroe, P. Barclay, F.K. Barlow, M. De Barra, D.V. Becker, L. Borovoi, I. Choi, J.A. Choi, N.S. Consedine, A. Conway, J.R. Conway, Li, Norman P., Jose C. Yong, D.E. Demirci, A.M. Fernandez, D.C.S. Ferreira, K. Ishii, I. Jaksic Nov 2016

Parasite Stress And Pathogen Avoidance Relate To Distinct Dimensions Of Political Ideology Across 30 Nations, J.M. Tybur, Y. Inbar, L. Aaroe, P. Barclay, F.K. Barlow, M. De Barra, D.V. Becker, L. Borovoi, I. Choi, J.A. Choi, N.S. Consedine, A. Conway, J.R. Conway, Li, Norman P., Jose C. Yong, D.E. Demirci, A.M. Fernandez, D.C.S. Ferreira, K. Ishii, I. Jaksic

Research Collection School of Social Sciences

People who are more avoidant of pathogens are more politically conservative, as are nations with greater parasite stress. In the current research, we test two prominent hypotheses that have been proposed as explanations for these relationships. The first, which is an intragroup account, holds that these relationships between pathogens and politics are based on motivations to adhere to local norms, which are sometimes shaped by cultural evolution to have pathogenneutralizing properties. The second, which is an intergroup account, holds that these same relationships are based on motivations to avoid contact with outgroups, who might pose greater infectious disease threats than …


Angels And Demons: Using Behavioral Types In A Real-Effort Moral Dilemma To Identify Expert Traits, Hernan Bejarano, Ellen P. Green, Stephen Rassenti Oct 2016

Angels And Demons: Using Behavioral Types In A Real-Effort Moral Dilemma To Identify Expert Traits, Hernan Bejarano, Ellen P. Green, Stephen Rassenti

ESI Publications

In this article, we explore how independently reported measures of subjects' cognitive capabilities, preferences, and sociodemographic characteristics relate to their behavior in a real-effort moral dilemma experiment. To do this, we use a unique dataset, the Chapman Preferences and Characteristics Instrument Set (CPCIS), which contains over 30 standardized measures of preferences and characteristics. We find that simple correlation analysis provides an incomplete picture of how individual measures relate to behavior. In contrast, clustering subjects into groups based on observed behavior in the real-effort task reveals important systematic differences in individual characteristics across groups. However, while we find more differences, these …


New Measures To Capture End Of Life Concerns In Huntington Disease: Meaning And Purpose And Concern With Death And Dying From Hdqlife (A Patient-Reported Outcomes Measurement System)., N E Carlozzi, N R Downing, M K Mccormack, S G Schilling, J S Perlmutter, E A Hahn, J S Lai, S Frank, K A Quaid, J S Paulsen, D Cella, S M Goodnight, J A Miner, M A Nance Oct 2016

New Measures To Capture End Of Life Concerns In Huntington Disease: Meaning And Purpose And Concern With Death And Dying From Hdqlife (A Patient-Reported Outcomes Measurement System)., N E Carlozzi, N R Downing, M K Mccormack, S G Schilling, J S Perlmutter, E A Hahn, J S Lai, S Frank, K A Quaid, J S Paulsen, D Cella, S M Goodnight, J A Miner, M A Nance

Rowan-Virtua School of Osteopathic Medicine Departmental Research

PURPOSE: Huntington disease (HD) is an incurable terminal disease. Thus, end of life (EOL) concerns are common in these individuals. A quantitative measure of EOL concerns in HD would enable a better understanding of how these concerns impact health-related quality of life. Therefore, we developed new measures of EOL for use in HD.

METHODS: An EOL item pool of 45 items was field tested in 507 individuals with prodromal or manifest HD. Exploratory and confirmatory factor analyses (EFA and CFA, respectively) were conducted to establish unidimensional item pools. Item response theory (IRT) and differential item functioning analyses were applied to …


The Interaction Between Perfectionism And Rumination Predicting State Self-Compassion, Caitlin A. Sharp Oct 2016

The Interaction Between Perfectionism And Rumination Predicting State Self-Compassion, Caitlin A. Sharp

Student Publications

Recent research has revealed self-compassion to be associated with many aspects of mental wellness. The present study investigates the relationship between perfectionism and rumination in predicting state self-compassion separately for both conscientious and self-evaluative forms of perfectionism. We hypothesized that perfectionism would interact with rumination in predicting state self-compassion such that there would be a negative association between occurrence of rumination and state-self compassion that would be more prominent in those with lower levels of perfectionism in regards to self-evaluative, but not conscientious perfectionism. To test these predictions, participants filled out a perfectionism inventory and completed a four minute ruminative …


A Closer Look At The Hedonics Of Everyday Meaning And Satisfaction, William Tov, Huey Woon Lee Oct 2016

A Closer Look At The Hedonics Of Everyday Meaning And Satisfaction, William Tov, Huey Woon Lee

Research Collection School of Social Sciences

Contrasts between eudaimonic well-being and hedonic well-being often compare meaning and happiness. Less work has examined the extent to which meaning and satisfaction can be distinguished. Across five diary studies (N = 923) and a large cross-sectional survey (N = 1471), we examined the affective profile of meaning and satisfaction in everyday life. Using response surface methodology, both judgments were modeled as a joint function of positive (PA) and negative (NA) affect. Affective discrepancy (preponderance of PA over NA) was more strongly associated with satisfaction than meaning. In general, meaning correlated less with affect than satisfaction, but the …


A Behavior Analytic Intervention To Teach Exploratory Motor Behavior To Infants With Down Syndrome, Sara M. Bauer Sep 2016

A Behavior Analytic Intervention To Teach Exploratory Motor Behavior To Infants With Down Syndrome, Sara M. Bauer

Dissertations, Theses, and Capstone Projects

Exploratory Motor (EM) behavior refers to manipulating a toy in the hand(s). Infants with Down syndrome demonstrate significant impairments in the duration and frequency of EM behavior compared to their typically developing counterparts. A behavior analytic intervention involving multiple opportunities, prompting, and social reinforcement was used to teach three infants with Down syndrome between 4-9 months of age to emit EM behavior. Results indicate that all three infants with Down syndrome emitted the three EM target behaviors to mastery and demonstrated generalized responding across stimuli and other EM behaviors. The importance of these findings in addressing impairments in infants with …


The Effects Of Descriptions And Images Of Antecedent Stimuli And Outcomes To Correct Responses In Task Analysis Instruction, Bryan C. Tyner Sep 2016

The Effects Of Descriptions And Images Of Antecedent Stimuli And Outcomes To Correct Responses In Task Analysis Instruction, Bryan C. Tyner

Dissertations, Theses, and Capstone Projects

Task analysis (TA) instruction is commonly used for teaching behavior chains; however, little research informs best practices for TA instruction. Data regarding the effects of instructional variables on responding may enhance TA efficacy and learner performance. Linking TA instruction to the three-term contingency may facilitate the development of control by stimuli that are naturally present while completing complex tasks; therefore, this study employed a two-by-two factorial design to analyze the relative effects of supplementing TA instruction with descriptions and images of: (factor A) antecedent stimuli relevant to each instructed discrete response and (factor B) the outcomes of accurately completing instructed …


Ptsd From Childhood Trauma As A Precursor To Attachment Issues, Christy Owen Sep 2016

Ptsd From Childhood Trauma As A Precursor To Attachment Issues, Christy Owen

Fidei et Veritatis: The Liberty University Journal of Graduate Research

The past 20 years have been turbulent regarding Reactive Attachment Disorder (RAD), with conflicting research about its causes, effects, treatment, and prognosis. The current diagnostic criteria in the DSM-5 fails to adequately address this disorder. A number of deviant and maladaptive behaviors common amongst children with RAD are not even mentioned in the diagnostic criteria. As such, the diagnostic definition is almost unidentifiable or incompatible with real-life conduct manifestations of the disorder. Rather, this author contends that RAD is foundationally a unique and extreme form of Posttraumatic Stress Disorder (PTSD) from Early Childhood Trauma. The child endured unspeakable neglect and/or …


A Collaborative Approach To Address Student Behavior And Academic Achievement Across Systems, Beverly Ngozi Okereke Sep 2016

A Collaborative Approach To Address Student Behavior And Academic Achievement Across Systems, Beverly Ngozi Okereke

Electronic Theses, Projects, and Dissertations

Academic achievement and in-classroom behaviors are two significant child outcomes that affect student success in school. According to Systems Theory, in order to truly understand the factors that affect these outcomes for children, one must look to the major systems that encapsulate the child (including their school and home environments). This project is a meta-analytic review that examined the effectiveness of measures representing each system in predicting child achievement and behavior: School-Wide Positive Behavior Supports (SWPBS) for the school as a system, level of parent involvement (high versus low) for the home system, and student motivation (intrinsic versus extrinsic) for …


Evaluation Of A Modified Incidental Teaching Procedure To Increase Child Compliance, Corey M. Cohrs Aug 2016

Evaluation Of A Modified Incidental Teaching Procedure To Increase Child Compliance, Corey M. Cohrs

Theses & Dissertations

Teaching noncompliant children to engage in compliant behavior has long been a goal for many parents, teachers, and therapists (Patterson, Shaw, & Ebner, 1969). This goal has driven the development of behavioral technology, including entire manualized treatment programs, specifically intended for the treatment of noncompliance (Forehand & McMahon, 1981; Hembree-Kigin & McNeil, 1995). These programs have typically included time-out based interventions that are associated with resistance to instruction (Roberts, 1982;Roberts, 1984). Given children’s frequent resistance to traditional approaches (e.g., timeout; Ducharme & Popynick, 1993), alternative interventions for the treatment of noncompliance are warranted.

A modified version of incidental teaching (Hart …


Automating Scoring Of Delay Discounting For The 21- And 27-Item Monetary Choice Questionnaires, Brent A. Kaplan, Michael Amlung, Derek D. Reed, David P. Jarmolowicz, Todd L. Mckerchar, Shea M. Lemley Aug 2016

Automating Scoring Of Delay Discounting For The 21- And 27-Item Monetary Choice Questionnaires, Brent A. Kaplan, Michael Amlung, Derek D. Reed, David P. Jarmolowicz, Todd L. Mckerchar, Shea M. Lemley

Research, Publications & Creative Work

Delay discounting describes the process wherein rewards lose value as a function of their delayed receipt; how quickly rewards lose value is termed the rate of delay discounting. Rates of delay discounting are robust predictors of much behavior of societal importance. One efficient approach to obtaining a human subject’s rate of delay discounting is via the 21- and 27-item Monetary Choice Questionnaires, brief dichotomous choice tasks that assess preference between small immediate and larger delayed monetary outcomes. Unfortunately, the scoring procedures for the Monetary Choice Questionnaires are rather complex, which may serve as a barrier to their use. This report …


An Evaluation Of The Acceptability And Effects Of A Computer-Delivered Values-Based Behavioral Activation Treatment For Depression Among Older Adults, Kellie Reynolds Aug 2016

An Evaluation Of The Acceptability And Effects Of A Computer-Delivered Values-Based Behavioral Activation Treatment For Depression Among Older Adults, Kellie Reynolds

Dissertations

Depression is a common psychological disorder among older adults and is associated with serious secondary effects to health and social well-being. Behavioral activation has been found to be an efficacious treatment for depression. However, there is limited research on the treatment effects of behavioral activation with older adults. In general, older adults under-utilize mental health treatments. Computer-delivered treatments have been developed to address access and under-utilization. The purpose of this dissertation was to evaluate the acceptability and effects of a computer-delivered values-based behavioral activation treatment for depression in older adults. This study consisted of two phases. Phase I consisted of …


Conceptualization, Measurement, And Effects Of Helicopter Parenting On College Students From The Millennial Generation, Baochun Z. Hind Aug 2016

Conceptualization, Measurement, And Effects Of Helicopter Parenting On College Students From The Millennial Generation, Baochun Z. Hind

Dissertations

The social phenomenon of helicopter parenting (HP) has been rapidly growing. Although HP is generally characterized as overly involved parents who “hover” over their college student children (Cline & Fay, 1990), and some research efforts have been made in recent years on understanding the construct of HP, an essential weakness of the majority of these studies is the inadequate conceptualization of HP, both theoretically and operationally. The aim of the current study was to develop a new scale to measure the construct of helicopter parent controlling (HPC), and three questions were used to guide this study: (1) What are the …


The Role Of Encoding Strategy In Younger And Older Adult Associative Recognition: A Think-Aloud Analysis, Mark C. Fox, Zachary Baldock, Sara P. Freeman, Jane M. Berry Aug 2016

The Role Of Encoding Strategy In Younger And Older Adult Associative Recognition: A Think-Aloud Analysis, Mark C. Fox, Zachary Baldock, Sara P. Freeman, Jane M. Berry

Psychology Faculty Publications

Older adults have especially poor recognition memory for word pairs, and recent research suggests this associative deficit manifests primarily in older adults’ higher rates of false alarms compared to younger adults. This could result from older adults either failing to generate meaningful (deep) mediators at study, or failing to benefit from having generated deep mediators at test. Younger and older adults performed a recognition memory task for words and word-pairs. A think-aloud analysis of their spontaneous encoding strategies (e.g., repetition, shallow mediators, and deep mediators) revealed that generation of deep mediators did not differ between younger and older adults, and …


The Effects Of Peer-Mediated Check-In, Check-Out With A Self Monitoring Component On Disruptive Behavior And Appropriate Engagement In The Classroom, Chandler Erin Mclemore Aug 2016

The Effects Of Peer-Mediated Check-In, Check-Out With A Self Monitoring Component On Disruptive Behavior And Appropriate Engagement In The Classroom, Chandler Erin Mclemore

Dissertations

Check-In/Check-Out (CICO) is a commonly used Tier II behavioral intervention within public school settings. The present study evaluated the use of an alternative method of service delivery for CICO that included peers as interventionists. Self-monitoring was an additional intervention component, utilized in order to reduce teacher response effort associated with intervention implementation. Three target student/peer interventionist dyads served as participants (one elementary school dyad, one middle school dyad, and one high school dyad). Direct observation data were collected, and the effects of peer-mediated CICO were evaluated with an ABAB design. Social validity measures were also completed by each teacher as …


A Functional Analysis Of Leader Behavior In A Behavioral Health Setting, Jason White Aug 2016

A Functional Analysis Of Leader Behavior In A Behavioral Health Setting, Jason White

All Theses And Dissertations

A requirement for Maine behavioral health organizations to provide all employees with evaluations lacks guidelines on how to evaluate leader behavior; best practices are to provide a multifaceted evaluation process that includes direct observation. A single-case research design and continuous partial interval recording procedures were conducted on a male behavioral health clinician leading clinical supervision in which the dependent variable was the clinician’s delivery of positive reinforcement and the independent variable was the provider’s increased discussion of case shares. The basic findings showed that leader behavior changed as follower behavior changed to manage the group and meet group goals. The …


Proposed Treatment Of Problematic Pornography Use: A Cognitive-Behavioral Approach, Jennifer Minarcik Aug 2016

Proposed Treatment Of Problematic Pornography Use: A Cognitive-Behavioral Approach, Jennifer Minarcik

Graduate Theses and Dissertations

As pornography use increases across the general population, mental health professionals are encountering more patients who present symptoms of sexual addictions and sexual compulsivity (Cooper et al., 2001). Never before have pornographic materials been so accessible to consumers. Viewing pornography is related to many negative consequences for the individual, including impairment of academic and professional functioning, subjective distress, and sexual compulsivity (Cooper et al., 1999a; Manning, 2006). Studies found pornography use by an individual typically leads to a decline in relationship and sexual satisfaction (Bridges, 2008a). Despite the growth in research related to problematic pornography use, to date there have …


Measure Athletes’ Volition—Short: Evidences For Construct Validity And Reliability, Ioannis Proios, Miltiadis Proios Jul 2016

Measure Athletes’ Volition—Short: Evidences For Construct Validity And Reliability, Ioannis Proios, Miltiadis Proios

Journal of Human Performance in Extreme Environments

The Measure Athletes’ Volition consists of 23 items that measure six elements of volitional competences. The purpose of the present study was to examine whether a subset of these items could form a short version of the scale; to provide evidence for the structural validity and internal consistency of the short version; and to test validity issues of the new scale. A total of 831 individuals from three different samples completed the long version of the scale. Results indicated that the short version consisted of 15 items that measured volitional competences of persistence, expediency, and purposefulness. This scale had acceptable …


Duration Of Time Spent Playing Online Video Games, Interpersonal Skills, And Introversion Personality Traits As Predictors For Social Anxiety Symptoms, James D. Bender Jul 2016

Duration Of Time Spent Playing Online Video Games, Interpersonal Skills, And Introversion Personality Traits As Predictors For Social Anxiety Symptoms, James D. Bender

Masters Theses & Specialist Projects

This study sought to determine if time spent engaging in online gaming, interpersonal communication skills, and introvert personality traits are predictors of an individual’s likelihood of experiencing symptoms of social anxiety. A sample of 128 participants (82 males and 46 females) completed measures of demographics, interpersonal communication skills, problematic online gaming, social anxiety, and introversion. Participants were recruited through Amazon Mechanical Turk. There were significant correlations among social anxiety and interpersonal communication skills, problematic online gaming, and introversion. There was no significant correlation among social anxiety and time spent playing Massively Multiplayer Online Role-Playing Games (MMORPG), a specific form of …


Evaluating Current Practices In Brief Experimental Analysis, Alex P. Isbill Jul 2016

Evaluating Current Practices In Brief Experimental Analysis, Alex P. Isbill

Masters Theses & Specialist Projects

Brief experimental analysis (BEA) has shown to be an effective method of rapidly testing the relative effects of two or more interventions in order to determine interventions that best supports a student’s learning. Little research has been found in regards to the consistency of methods across studies. A meta-analysis in 2008 by Burns and Wagner looked at BEAs that assessed oral reading fluency and provided recommendations for future practice. This study investigates the methods, procedures, and outcomes in BEA studies from 1994 to 2016. The findings of this study are compared to Burns and Wagner’s (2008) recommendations from their meta-analysis, …


Nonsuicidal Self-Injury Characteristics As Predictors Of A Suicide Attempt, Kandice M. Perry Jul 2016

Nonsuicidal Self-Injury Characteristics As Predictors Of A Suicide Attempt, Kandice M. Perry

Masters Theses & Specialist Projects

This study examines the impact features of nonsuicidal self-injury (NSSI) have on predicting a suicide attempt in a sample of young adult self-injurers. Participants completed the Inventory of Statements About Self-Injury, the Self-Harm Behavior Questionnaire and demographics questionnaires to assess lifetime self-injury frequency, number of different methods used, severity of methods, the desire to stop self-harming, functions, the experience of pain, and response latency. Results indicated that NSSI frequency, high severity methods, and endorsing more intrapersonal functions predicted the presence of a suicide attempt. Additionally, those who experienced pain while selfinjuring were found to be significantly more likely to report …


The Influence Of Happy Faces On Spatiotemporal Vision, Siera Nicole Bramschreiber Jul 2016

The Influence Of Happy Faces On Spatiotemporal Vision, Siera Nicole Bramschreiber

Masters Theses & Specialist Projects

Past research demonstrates that fearful faces lead to an increase in temporal and a decrease in spatial gap detection, an effect proposed to be caused by a flow of input to the magnocellular pathways from the amygdala to the visual system (Bocanegra & Zeelenberg, 2009). The amygdala is also active for positive and arousing stimuli, including happy faces. The current study extends past research by presenting happy facial cues just before a gap detection task. Facial stimuli (i.e., happy/neutral faces) were presented in the periphery of the receptive field and quickly followed by a Landolt circle. Half of the participants …


The Effect Of Emotional Faces On The Attentional Blink In Younger And Older Adults, Allison M. Sklenar Jul 2016

The Effect Of Emotional Faces On The Attentional Blink In Younger And Older Adults, Allison M. Sklenar

Masters Theses & Specialist Projects

The attentional blink occurs when detection of a second target (T2) is impaired when it occurs between 180 to 450 ms after the first target (T1) in a rapid serial visual presentation (RSVP). The attentional blink can be affected by relevant emotional stimuli, like emotional faces, such that an emotional T1 enhances the attentional blink, and an emotional T2 attenuates it. However, not all studies use the same type of face stimuli, and there is debate over whether schematic and photo-realistic faces are processed in the same way. Furthermore, the effect of emotion on the attentional blink should differ with …


Computational Modeling Of Facial Response For Detecting Differential Traits In Autism Spectrum Disorders, Manar D. Samad Jul 2016

Computational Modeling Of Facial Response For Detecting Differential Traits In Autism Spectrum Disorders, Manar D. Samad

Electrical & Computer Engineering Theses & Dissertations

This dissertation proposes novel computational modeling and computer vision methods for the analysis and discovery of differential traits in subjects with Autism Spectrum Disorders (ASD) using video and three-dimensional (3D) images of face and facial expressions. ASD is a neurodevelopmental disorder that impairs an individual’s nonverbal communication skills. This work studies ASD from the pathophysiology of facial expressions which may manifest atypical responses in the face. State-of-the-art psychophysical studies mostly employ na¨ıve human raters to visually score atypical facial responses of individuals with ASD, which may be subjective, tedious, and error prone. A few quantitative studies use intrusive sensors on …


Behavioral Economic Analyses Of Reinforcement In The Experimental Analysis Of Human Behavior, James Allen Chastain Jul 2016

Behavioral Economic Analyses Of Reinforcement In The Experimental Analysis Of Human Behavior, James Allen Chastain

Theses and Dissertations

Evidence-based advances in the field of Behavior Analysis have begun to demonstrate ways in which behavioral-economic methods may provide a coherent understanding of responding and consumption of reinforcers. This dissertation extends the literature to behavioral-economic analyses of programmed video reinforcement in the experimental analysis of human behavior (EAHB), as well as a novel reinforcement arrangement for reduction of in-session duration. Three aims served to guide this study: (a) demonstrate the feasibility and utility of behavioral-economic assessments of reinforcement in EAHB, (b) extend economic predictions of unit price to video reinforcement arrangements, and (c) evaluate the utility of an exponential model …


No Sweat: African American Adolescent Girls’ Opinions Of Hairstyle Choices And Physical Activity, Susan J. Woolford, Carole Woolford-Hunt, Areej Sami, Natalie Blake, David R. Williams Jul 2016

No Sweat: African American Adolescent Girls’ Opinions Of Hairstyle Choices And Physical Activity, Susan J. Woolford, Carole Woolford-Hunt, Areej Sami, Natalie Blake, David R. Williams

Faculty Publications

Background

Obesity prevalence is higher among African American adolescent (AAA) girls than among non-black girls. Lower levels of physical activity (PA) likely contribute to this disparity; this may be impacted by hairstyle concerns.

Methods

In 2011, focus groups were conducted with AAA girls 14-17 years old (n = 36) in Michigan (n = 9), California (n = 11), and Georgia (n = 16). Groups addressed perceptions of hairstyles, exercise, and relationships between the two. Groups were recorded, transcripts reviewed, and themes identified. Adolescents completed a standardized ethnic identity (EI) measure and a survey addressing demographics and …


Human Choices Between Variable And Fixed Rewards In Hypothetical Variable-Delay And Double-Reward Discounting Procedures, Todd Mckerchar, James E. Mazur Jun 2016

Human Choices Between Variable And Fixed Rewards In Hypothetical Variable-Delay And Double-Reward Discounting Procedures, Todd Mckerchar, James E. Mazur

Research, Publications & Creative Work

Prior research has shown that nonhumans show an extreme preference for variable- over fixed-delays to reinforcement. This well-established preference for variability occurs because a reinforcer’s strength or “value” decreases according to a curvilinear function as its delay increases. The purpose of the present experiments was to investigate whether this preference for variability occurs with human participants making hypothetical choices. In three experiments, participants recruited from Amazon Mechanical Turk made choices between variable and fixed monetary rewards. In a variable-delay procedure, participants repeatedly chose between a reward delivered either immediately or after a delay (with equal probability) and a reward after …


The Behavioral Analysis Of Gambling, Benjamin Witts, Anne Macaskill, Mack Costello Jun 2016

The Behavioral Analysis Of Gambling, Benjamin Witts, Anne Macaskill, Mack Costello

International Conference on Gambling & Risk Taking

A behavioral analysis of gambling is unique among the psychologies. A behavioral analysis seeks answers to questions pertaining to the prediction and influence of gambling in terms of the individual gambler, and thus emphasis is placed on well-controlled small-n studies in which findings are generalized to other individuals. Further, the behavioral analysis of gambling is concerned with environmental and historical relations in accounting for current gambling behavior, and less of a reliance is placed on internal and hypothetical causal factors. This symposium explores two data-driven analyses of gambling behavior from a behavioral account of gambling while a third conceptual and …
