The purpose of this thesis is to examine the problem of employing unidimensional deterministic scaling in a multidimensional probabilistic world. The best known unidimensional deterministic scaling method is Guttman scaling. The scope of inquiry is limited to scaling with four dichotomous scale items. As a consequence of this examination, the paper offers two contributions to the study of scaling. First, it identifies two paradoxes of existing unidimensional deterministic scaling methods....
Show moreThe purpose of this thesis is to examine the problem of employing unidimensional deterministic scaling in a multidimensional probabilistic world. The best known unidimensional deterministic scaling method is Guttman scaling. The scope of inquiry is limited to scaling with four dichotomous scale items. As a consequence of this examination, the paper offers two contributions to the study of scaling. First, it identifies two paradoxes of existing unidimensional deterministic scaling methods. Second, it suggests a general framework, called segment analysis, from which to approach unidimensional deterministic scaling with dichotomous scale items.

Service learning is a pedagogy designed to teach democratic skills to prepare students to become civically engaged members of society. One of the challenges in the field of service learning is to demonstrate the effectiveness of this pedagogy. Common methodological problems include small sample sizes, difficulty differentiating correlation from causation, self-selection bias, and use of primarily qualitative and experiential outcome measures.

Show moreService learning is a pedagogy designed to teach democratic skills to prepare students to become civically engaged members of society. One of the challenges in the field of service learning is to demonstrate the effectiveness of this pedagogy. Common methodological problems include small sample sizes, difficulty differentiating correlation from causation, self-selection bias, and use of primarily qualitative and experiential outcome measures. The literature review failed to reveal any quantitative scales designed for the health professions. The purpose of this study was to develop and test a quantitative scale to measure service learning outcomes among health professions students, before and after an academic service learning activity. Phase 1 of the study, the development phase, involved an extensive review of the literature to develop the conceptual framework and identify the operational indicators to be measured. Items were adapted from existing scales that were consistent with the personal and social responsibility dimensions and found to possess at least minimally acceptable reliability and validity. Items were adapted to add the health professions perspective which resulted in the preliminary twenty-two item scale, divided into four subscales: Civic Responsibility, Self-Efficacy Toward Service, Civic Participation, and Social Justice Attitudes. Psychometric testing of this preliminary PSR Scale was done in 3 studies. Study 1 involved evaluation of content validity with subject matter experts utilizing a Content Validity Index. The scale was modified based on the results of the CVI and recommendations of the subject matter experts. The S-CVI/Ave for the entire scale was .84 suggesting content validity of the PSR Scale. Study 2 utilized principal components analysis of the subscales to validate the dimensions and operational indicators. Data was constrained to four factors which accounted for 60.56% of the total variance. Items with factor loadings less than 0.4 were deleted. Cronbach’s alpha coefficient was calculated for internal consistency. Based on these results, the scale was further revised by deleting items that decreased the Cronbach’s alpha. This resulted in a 16 item scale, containing four subscales, each with four items. The Cronbach’s alpha for the entire revised scale PSR Scale was .94. Study 3 involved testing the final 16 item version for sensitivity. Wilcoxon signed rank analysis revealed statistically significant changes pre and post service learning activity in the Civic Participation Subscale. Civic Participation Subscale items that were significant included “volunteering time to support my community”, “being involved in programs and activities that improve my community”, and “being involved in activities that improve the health of my community”. These findings suggest that participation in a service learning activity can increase civic participation. Psychometric testing of the Personal and Social Responsibility Scale (PSR) support preliminary validity, reliability and sensitivity of the instrument and the premise, consistent with prior research that changes in civic participation can occur as a result of service learning.

- It’s all just in your head: How does a person’s cultural identity affect their flood risk perceptions and mitigation behaviors?.
- Creator
- Oglesby, Glen E., Polsky, Colin, Florida Atlantic University, Department of Geosciences, Charles E. Schmidt College of Science
- Abstract/Description

As flood risk rises in the U.S., technology and insights rise too, but even with these advances we still see the consequences of flood risk. Together, the rational actor paradigm (“RAP”), psychometrics, and cultural theory help to explain risk perceptions and behaviors of 20 respondents. Results from the mixed-methods approach found the RAP insufficient, less accurate than a coin toss (48%), when explaining respondent behaviors. Rather, risk perceptions and behaviors of the RAP explain the...
Show moreAs flood risk rises in the U.S., technology and insights rise too, but even with these advances we still see the consequences of flood risk. Together, the rational actor paradigm (“RAP”), psychometrics, and cultural theory help to explain risk perceptions and behaviors of 20 respondents. Results from the mixed-methods approach found the RAP insufficient, less accurate than a coin toss (48%), when explaining respondent behaviors. Rather, risk perceptions and behaviors of the RAP explain the behaviors of lower risk portrayal groups (66%) and higher income groups (80%), with higher risk portrayals being relying on respondents’ trust in flood experts (45%) and cultural worldviews (55%). Cultural identities explain 65% of respondents’ behaviors across levels of risk portrayal (500-, 100-, and 25-year floodplain), and risk portrayal types (cumulative and AAL). In a world with increased risk, technology, and knowledge, researchers need understand the explanatory power of the RAP, psychometrics, and cultural theory.

- Title
- A Hebbian characterization of mismatch negativity.
- Creator
- Starratt, Gerene K., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
- Abstract/Description
-
Mismatch Negativity (MMN) is a component of the event-related potential (ERP) that is associated with the detection of novel stimuli in one's environment. Naatanen has suggested that a neural template theory provides the best explanation of the mechanism that underlies this psychophysiological phenomenon. The purpose of the present project was to propose that a Hebbian model of cell-assemblies (Hebb, 1949) provides a plausible competing theory of MMN. A Hebbian model is consistent with the...
Show moreMismatch Negativity (MMN) is a component of the event-related potential (ERP) that is associated with the detection of novel stimuli in one's environment. Naatanen has suggested that a neural template theory provides the best explanation of the mechanism that underlies this psychophysiological phenomenon. The purpose of the present project was to propose that a Hebbian model of cell-assemblies (Hebb, 1949) provides a plausible competing theory of MMN. A Hebbian model is consistent with the evidence provided by imaging studies that demonstrate increased neural efficiency in learning cognitive (as opposed to skilled motor) tasks and with recent animal studies in an analogous model. This model suggests three hypotheses which were addressed by the present study. First, it is proposed that the method that is traditionally used to calculate MMN may not be the ideal. Specifically, it is proposed that the baseline measure used in the calculation does not yield optimal MMN data and the present experiment investigated a new method of gathering baseline data. Second, it was hypothesized that an investigation of sequence effects related to standard and deviant stimuli in an oddball paradigm would provide further support for a Hebbian reinterpretation of MMN. Finally, the argument is made that a Hebbian model of MMN garners additional support in terms of parsimony and ecological validity in addition to being consistent with our current understanding of the physiological underpinnings of learning phenomena. Results indicate that the new method of calculating MMN does, indeed, provide a more robust measure of MMN. Furthermore, sequence effects were demonstrated for both the standard and deviant stimuli, however the sequence effects observed in standard stimuli were not in the expected direction. Both practical and theoretical implications are discussed.

The purpose of this study was to develop and explore the factor structure of a retrospective assessment instrument designed to identify the presence of early covert traumas in an individual’s history. Covert traumas are those which are psychosocial, and often interpersonal, in nature (Altobelli, 2017).

Show moreThe purpose of this study was to develop and explore the factor structure of a retrospective assessment instrument designed to identify the presence of early covert traumas in an individual’s history. Covert traumas are those which are psychosocial, and often interpersonal, in nature (Altobelli, 2017). While a deficiency in the available body of research addressing such traumas currently exists, limited research suggests that experiences of such phenomena may affect individual potential across various domains of development, functioning, health, and well-being (van der Kolk, 2014). In addition, the residual effects of such traumas may exacerbate adverse adult outcomes, such as experiences of chronic pain, proclivities towards maladaptive forms of coping, and hindrances to academic and occupational performance and achievement (Felitti et al., 1998). Furthermore, some theorists propose that the impact of such traumas, especially when compounded, may cause more emotional harm than exposure to a single overtly traumatic event (Staggs, 2014).

Argument is made for the use of variation permissive methods in the study of social judgment; one such dynamic method which purports to track on-line social evaluation (the mouse paradigm) is then introduced. The methodology of the mouse paradigm, which involves updating 'moment-to-moment' feelings via manipulation of a cursor by computer mouse, permits a wide range of experimental contrivance. Three varieties (SCALE, 1D and 2D), which differ in the amount of virtual (on screen) freedom of...

The methodology of the mouse paradigm, which involves updating 'moment-to-moment' feelings via manipulation of a cursor by computer mouse, permits a wide range of experimental contrivance. Three varieties (SCALE, 1D and 2D), which differ in the amount of virtual (on screen) freedom of movement and psychological constraint, were tested with stereotyped targets (negative, ambivalent and positive) to determine any differences in their absolute distance time series and the extent to which aspects of these time series remained correlated with traditional scale-ratings of positivity and stability in feelings about targets. Results indicated a sharp difference between the two-dimensional (2D) variety and the one-dimensional varieties (SCALE and 1D), a finding which supports contention that the 2D variety possesses an appropriate balance of freedom and constraint.
