The present study examines the relationship of emotional awareness to anticipatory psychophysiological markers and performance on the Iowa Gambling Task (IGT). The IGT is a computerized card game that simulates real-life decisions through uncertainty of reward or punishment. The participant’s goal is to make advantageous card choices. Anticipatory somatic markers of physiological arousal, like electrodermal activity and heart rate, have been proposed to bias decisions in the IGT. The central hypothesis is that a participant’s emotional awareness is related to their ability to make advantageous decisions through biasing psychophysiological responses. The Toronto Alexithymia Scale was used to assess each participant’s emotional awareness. Less emotional awareness was associated with enhanced performance on the IGT. However, anticipatory physiological arousal (electrodermal activity and heart rate) and emotional awareness yielded no significant relationships. Findings suggest a need for further research on cognitive models, such as the expectancy valence model, in relation to decision-making.

Currently, there is no standard protocol to identify students who are gifted in science. If students are identified as gifted early on in elementary school, teachers and parents can foster their interest, increasing the students’ knowledge, value, and affect as well as their willingness to re-engage science (Eccles & Wigfield, 2002; Gottfried & Gottfried, 1996; Häussler 1987; Neber & Schommer-Aikins, 2002; Osborne, 2003; Schunk, Pintrich, & Meece, 2008). In this study, a brief student identification form was developed for elementary school teachers to complete. The form was based on Hidi and Renninger’s (2006) four-phase model of interest development. The form was one piece of a more comprehensive identification protocol. Students in grades second, third, fourth, fifth, and sixth from six Warren County elementary schools were asked to participate in this study. However, due to insufficient data, grades two and six were not used after collection. Few sixth grade teachers completed the forms and second graders did not take the ITBS. This study primarily focused on identifying students from underrepresented populations. These six schools, Cumberland Trace, Bristow, Lost River, Oakland, Richardsville, and North Warren, were chosen based on their larger population of students who qualify for free and reduced lunch.

This study examined the theoretical basis for decision making behavior of patients with right or left temporal lobectomy and a control group when they participated in the Iowa Gambling Task. Two cognitive decision models, Expectancy Valence Model and Strategy Switching Heuristic Choice Model, were compared for best fit. The best fitting model was then chosen to provide the basis for parameter estimation (sources of decision making, i.e. cognitive, motivational, and response processes) and interpretation. Both models outperformed the baseline model. However comparison of G2 means between the two cognitive decision models showed the expectancy valence model having a higher mean and thus a better model between the two. Decision parameters were analyzed for the expectancy valence model. The analysis revealed that the parameters were not significant between the three groups. The data was simulated from the baseline model to determine whether the models are different from baseline.
