This study attempted to determine the specific mathematics necessary to a student in a beginning course in behavioral science research statistics. To determine the most desirable form for a review of mathematics prior to a research statistics course,, it was first necessary to determine the following: (1) the specific overall content of such a course, (2) the specific mathematics topics of such a course, and (3) the specific mathematics operations utilized in such a course. The study consisted of three parts. The first phase was a determination of the content of a typical beginning course in research statistics for the behavioral sciences. To make this determination, a survey was conducted among forty universities chosen by random sampling from those in the United States offering the Doctor of Education degree. Course outlines and textbooks used by these universities were analyzed, and topics were tabulated. In addition, a selection of recent statistics texts was analyzed, and these topics were also tabulated. These tables were used as a means of content determination.

Diese Dissertation unterstreicht die Rolle von Informationen bei der Erforschung ökonomischer Entscheidungen. Das erste Kapitel beschäftigt sich mit dem Zugang zu akkuraten Informationen über die Wirksamkeit medizinischer Interventionen. Unserem Model zufolge besteht in vielen entwickelten Ländern Nachfrage für Zugang zu unabhängigen medizinischen Informationen wie Cochrane Reviews. Wir schätzen, dass für viele Länder diese Nachfrage zu moderaten oder geringen Kosten erfüllt werden kann. Das zweite Kapitel beschäftigt sich mit der Kommunikation solcher Informationen und untersucht den unterstützenden Effekt natürlicher Häufigkeiten bei der Berechnung von A-posteriori Wahrscheinlichkeiten (Gigerenzer & Hoffrage, 1995). Durch eine Meta-Analyse erklären wir Konzepte und entflechten die Effekte von 15 Studienmerkmalen. Im einfachsten Studiendesign führen natürliche Häufigkeiten zu 24 Prozent korrekten Antworten verglichen mit 4 Prozent bei konditionellen Wahrscheinlichkeiten. Die finalen beiden Kapitel analysieren Satisficing-Strategien für unsichere Entscheidungsumgebungen in denen Agenten eine vollumfassende, probabilistische Beschreibung des Entscheidungsproblems fehlt. Simon (1955) zufolge nutzen Satisficing-Strategien ein Anspruchsniveau um die Suche nach weiteren Entscheidungsalternativen zu beenden. Das dritte Kapitel beschreibt wie solche Strategien in der ökonomischen Literatur als Präferenz modelliert werden um Entscheidungen zu erklären die der Nutzenmaximierung unterlegen sind während die Kognitionswissenschaften diese Strategien als Lösungen für Inferenzprobleme betrachten. Wir erklären die Divergenz mit unterschiedlichen Annahmen über die vorliegenden Informationen der Agenten. Das letzte Kapitel untersucht Satisficing-Strategien unter Taxifahrern. Wir stellen fest, dass die Stundenlöhne von Taxifahrern kaum vorhersagbar sind und ihre Entscheidungen Schichten zu beenden am besten durch einfache Satisficing-Strategien vorhergesagt werden können. / This doctoral thesis emphasizes the significance of informational conditions in studying economic decisions. The first chapter concerns access to accurate probabilistic information in the domain of medical interventions. We estimate that, in many developed countries, there appears to be demand for governments to grant citizens free access to impartial reviews of medical evidence, as provided in Cochrane Reviews. For these countries, we estimate that this demand can be met at low costs. The second chapter concerns the communication of such information and examines the facilitating effect of natural frequencies on the derivation of posterior probabilities, as delineated by Gigerenzer and Hoffrage (1995). In a meta-analysis, we clarify concepts and disentangle the effects of 15 study characteristics. We find that in the simplest study design, 4 percent correct solutions when presented with conditional probabilities and 24 percent when presented with natural frequencies. The final two chapters examine the satisficing class of strategies for uncertain decision environments in which agents lack a full probabilistic description of the decision problem. According to Simon (1955), satisficing strategies use aspiration levels to terminate search for suitable alternatives. The third chapter describes how in economics, satisficing is modeled as a preference structure or as a decision rule that yields choices inferior to utility maximization, whereas in cognitive science, satisficing strategies use aspiration levels to solve inference problems. We explain the divergence, noting that they refer to risky and uncertain environments, respectively. The final chapter examines satisficing in an applied setting, studying taxi drivers' shift termination behavior. We find that drivers' hourly earnings are very uncertain and drivers’ behavior is best predicted by simple satisficing strategies that terminate shifts when reaching an aspired shift income or shift duration.

For many decades there has been an ongoing feud between the fields of behaviorism and cognitive science. This feud is not about specific scientific findings, it is about deep philosophical convictions, and about what terms and methods it makes sense to use when studying psychology. In the late 1950’s, behaviorism was declared dead when it was convincingly argued that behaviorism could not explain the nature of language, a centerpiece of human psychology. But since then behaviorism has slowly risen from its grave, as a new behaviorist theory of language emerged. The new behaviorist theory of language is called Relational Frame Theory (RFT), and it is part of a new behaviorist paradigm called Contextual Behavioral Science (CBS). This paradigm also includes a behaviorist psychotherapy called Acceptance and Commitment Therapy (ACT), which in the last decade has become popular across the world. Thus, the feud has once again become active, and the question about which philosophical principles are most suitable for the science of psychology is yet again something that needs an answer. But things have changed since the mid-1900’s when the discussion was last active. The philosophy of CBS is not exactly like that of earlier versions of behaviorism, having developed into a more explicit and coherent set of philosophical principles, summarized under the name functional contextualism. Old arguments against behaviorism do not apply to the same degree. So it is time for a new look at this debate, taking into consideration what functional contextualism and RFT has to offer. According to Contextual behavioral science, cognitive science generally entails a commitment to the correspondence theory of truth, the idea that something is true if it corresponds with reality, or a worldly fact. CBS, on the other hand, makes an explicit commitment to a pragmatic theory of truth, which focuses on the consequences (i.e. usefulness) of a statement or theory, instead of its correspondence with reality. Because of the supposed centrality of these theories of truth for the divide between cognitive science and behaviorism, I will focus on what exactly this divide is about, and whether there is any way that the differences can be reconciled. I will argue that the divide isn’t as big as it may seem when we take a closer look at the philosophical principles and empirical theories of CBS, and that it may in fact be possible to bridge this divide by formulating a version of the correspondence theory that is compatible with CBS. In part 1 I present a quick sketch of behaviorism as contrasted with cognitive science, and the connection between behaviorism and the pragmatic theory of truth, as well as the connection between cognitive science and the correspondence theory of truth. In part 2 I give a more detailed description of the philosophy and science of Contextual behavioral science, including the tools for understanding language in CBS terms. In part 3 I present a more detailed description of the correspondence theory of truth, giving an overview of the different versions of this theory that have been proposed throughout the history of philosophy. In part 4 I make a careful evaluation of the CBS objections towards the correspondence theory of truth, and arrive at a version of the correspondence theory that can be expressed in CBS terms. I will conclude that this version is compatible with the underlying philosophy of CBS, even though the CBS pragmatic theory of truth claims otherwise. I call it a behaviorist correspondence theory of truth.

We used a multiple-baseline across participants and combined reversal and multielement design to assess the effects of contingent-token-reinforcement, compared to noncontingent-token-reinforcement, on moderate-to-vigorous physical activity (MVPA) exhibited by four preschool-aged children. Three children engaged in higher levels of MVPA when tokens were delivered contingent on MVPA compared to baseline (no token) and noncontingent-token conditions. Although MVPA was differentiated across contingent-token sessions and corresponding baseline (no token) control probes for three of the four participants, some variability was apparent. The present study demonstrated that the delivery of tokens contingent on MVPA can increase and maintain MVPA exhibited by preschool-aged children, resulting in more MVPA than in baseline conditions and conditions in which tokens are awarded without respect to MVPA.

Hermetic storage systems represent viable pest control methods for postharvest crop storage. Nevertheless, there is limited understanding of how insect respond to hypoxic conditions inside hermetic storage. This study was conducted to investigate: i) the oxygen consumption behavior of T. castaneum under hermetic conditions, and effects of hypoxia exposure on: ii) the survival of different life stages after hypoxia iii) their feeding and movement (activity), and iv) the cellular energy as a measure of adenylate energy charge (AEC). T. castaneum consumed 6.80 ± 0.45 mL of oxygen during egg-to-adulthood while adults consumed 5.37 ± 0.30 mL of oxygen during 21-d at 27°C. The daily rate of oxygen utilization increased with increasing temperature and in larger volume containers. Eggs and young larvae were the most susceptible stages, experiencing total mortality when exposed to 2% oxygen level for 3d compared to larvae and pupae (required ≥10 d), and adults (required ≥15 d). At 4% oxygen level, total mortality was achieved for eggs and other life stages at 5 d and ≥15 d, respectively. By contrast, the 8% oxygen level was not lethal except for eggs, but it caused significant developmental delays in immatures. Likewise, the ultrasonic device revealed that hypoxia exposure could affect insect activity within the first 30 minutes of treatments. Furthermore, the AEC index of T. castaneum adults at normoxia control was 0.70 ± 00, while the AEC at <1%, 2, 4, 8% oxygen levels were 0.18 ± 0.0, 0.19 ± 0.01, 0.25 ± 0.02, and 0.58 ±0.01, respectively suggesting that hypoxia diminish energy production in insect cells. Complete mortality of T. castaneum adults was achieved when exposed to <1% oxygen levels for 96 h. In conclusion, exposing T. castaneum to <2% oxygen levels for 15 d produce total mortality; however, even the higher levels of oxygen at 4-8% can subtly affect insect population development.

Behavioral science faculty (BSF) who work in family medicine residency education find themselves in inpatient medicine teaching service settings. However, there is limited research on the roles and responsibilities that BSF fill while working in inpatient medicine teaching services within family medicine residencies. The purpose of the present modified sequential explanatory study was to clarify the roles of BSF and how the BSF responsibilities inform training of mental health clinicians. The convenience sample for quantitative analysis included 60 BSF who currently work on an inpatient medicine teaching service and completed a web-based survey on contextual demographics and roles on inpatient medicine teaching service. The convenience sample for qualitative analysis included 24 BSF who participated in a semi-structured interview about the roles and responsibilities on an inpatient medicine teaching service. Results suggest that behavioral science faculty members assume the roles of Educator, Administrator, Patient Care Supporter, Evaluator, Scholar/Researcher, Community Service Liaison, Mentor/Advisor, and Gatekeeper, and perform multiple responsibilities within each role. I will identify the responsibilities within each role that BSF fill in inpatient medicine teaching services using qualitative analysis and explore discrepancies between previous frameworks and this study's outcomes. Implications for this research will help to inform the hiring process for behavioral science faculty, resident education, and comprehensive behavioral science faculty and marriage and family therapy training. / Ph.

Sustainability is a complex socio-technical challenge that requires new ways of thinking. To help meet this challenge, I have created three case-based modules that teach engineering students how to apply sustainability principles and help them recognize potential cognitive traps, or barriers, that may prevent more consideration for sustainability during design. Each of my three case studies is built into a PowerPoint-guided module for undergraduate engineering classes, which may be taught in 1-3 class days. I have implemented each of the three modules in senior-level classes at Virginia Tech, assessed survey data, and scored student assignments. This work and the underlying literature background is reflected in three journal papers, one for each module. My case study modules, along with all associated teaching materials, are shared in the Center for Sustainable Engineering repository for other instructors to adapt and use. Each module includes a case study about an infrastructure project recognized and awarded by the Envision rating system, demonstrating a case of sustainability done well. Adaptable PowerPoint slides are used to teach about the Envision rating system and credits particularly relevant to the project. Active learning assignments allow students to apply the Envision framework and design criteria to complex and ill-structured problems related to the case study. Slides also cover the relation of three selected behavioral decision science concepts to each case study; these include cognitive biases and barriers which tend to inhibit sustainability outcomes, as well as some potential solutions to mitigate or overcome such barriers. Paired with the decision-making framework of Envision, awareness of these transdisciplinary concepts will allow students to more effectively manage the complex decisions found in real-world projects. Results were assessed through a variety of methods to determine the modules' level of effectiveness in accomplishing defined student learning outcomes. Pre-module and post-module student surveys were employed to measure several indicators: changes in self-assessed confidence levels, perceptions of sustainable design (characteristics and barriers), and accuracy of module concept definitions. Each of several active learning assignments was scored on a simple rubric. Concept maps were also tested as further type of assessment, and scored with both traditional and holistic methods. However, fully integrating the concept mapping approach is left to the future work of others. These modules are a significant contribution to engineering education, as they integrate diverse topics and disciplines into a unified and relevant teaching package. Over 350 students have already been reached through the three modules, and sharing the materials in a peer-reviewed repository allows for expansion, adaptation, and capacity building. Each module's content and pedagogy align with ABET accreditation requirements and ASCE's Body of Knowledge, making them relevant tools for equipping the future generation of engineers. Future development of similar case studies can build partnerships between academia and industry, as well as increase cross-disciplinary collaboration. These efforts will both improve undergraduate education and advance the profession. / Master of Science

The purpose of this thesis was to determine the proportion of participants enrolled in a community-based weight loss program that would accept and use a wearable device (Fitbit) if included as part of the program. A sample of 526 newly enrolled, adult, female weight loss program participants (BMI ≥ 30 kg/m2 ) were recruited. Participants were randomized to either a Fitbit experimental condition or no-Fitbit control condition, and received emailed information on program features. The experimental condition email also included a free Fitbit offer. The full sample (n=526) was 44±12.6 years old with a BMI of 37±6.2 kg/m2. The proportion of experimental sample (n=266) that accepted and synced was 50% and 23%, respectively. Twenty-two participants in the control condition (8%) also independently obtained and synced a Fitbit. Ninety-nine percent passively declined (did not respond to request for Fitbit color and size information). Those that declined were older (46±13.4 vs. 42±11.3 years of age, p=.001) and weighed less (214±38.9lbs. vs. 231±41.3lbs., p=.01) than those who accepted. Those in the experimental sample who synced were younger (42±10.0 vs. 45±13.2 years of age, p=.012), and weighed more (237±45.2lbs. vs. 217±38.1lbs., p=.002) than those who accepted but did not sync. This thesis provides preliminary support that 23% of participants will accept and sync a free wearable device. These data can be used for decision making, combined with effectiveness and cost data, and research on wearable activity trackers and community, incentive, and web-based weight loss. / Master of Science

Purpose:The purpose of this master dissertation is to examine current research on trust and its building process in business to business relationship from marketing and behavioral sciences perspectives. Research Questions: (1) What relationships do inter-organizational trust and inter-personal trust have? (2) How trust is built from perspectives of business and behavioral sciences? (3) What benefits and limitations do trust researches in behavioral sciences have, comparing to trust research in marketing? Research Design/Methodology: Qualitative research conducted a literature review between business administration and behavioral sciences, and interdisciplinary interviews with nine scholars and four business managers. Meanwhile, criteria are generated to ensure research quality. Findings: The finding of this research claims that interpersonal and interorganizational trusts are linked with organizational learning theory. Trust-building process is a social cognition sequence, which developed based on theory of social cognition and social interaction. A conceptual framework of trust-building process on the basis of social cognition was developed. Managerial Implications: This research suggests that mangers need to improve companies’ learning and cognition capability in order to identify new business opportunities, reduce the risk on mistakenly trust ineptitude partners, and increase companies’ competitive advantages.
