Effect Of A Learned-Threat On Pain Perception And Behaviors, Eric Kruger
Effect Of A Learned-Threat On Pain Perception And Behaviors, Eric Kruger
Psychology ETDs
Pain is an adverse experience and a motivating force which allows for effective responding to environmental threats. There has been limited research in how pain related consequences can be learned outside of direct experience. The purpose of this study was to investigate if a non-painful threatening stimulus can modulate pain behavior. Forty-three male participants were trained via a computer task to respond to a threatening visual symbol (i.e. learned-threat). Participants also completed a painful task, a cold-pressor task (CPT), prior to and after threat training and were randomly assigned to threat/non-threat conditions during a CPT after the threat training. Repeated …

Understanding The Learning Benefits Associated With Transcranial Direct Current Simulation Of The Right Ventrolateral Prefrontal Cortex, Benjamin C. Gibson
Psychology ETDs
Previous work has demonstrated that anodal transcranial direct current stimulation (tDCS) applied to the right ventrolateral prefrontal cortex (rVLPFC) is capable of accelerating learning of a threat identification and classification task. However, questions remain as to the cognitive mechanisms underlying this effect, and whether the observed tDCS mediated learning is specific to threatening stimuli or, rather, a more generalizable learning processes. The goal of the current project was to isolate specific aspects of the threat detection task in order to exemplify previous findings. A number of pre-test measures were included to attempt to decipher the characteristics of subjects who are …

Our ability to make informed decisions about ebooks is constrained by our limited understanding of how students perceive and use them. A team of librarians and a professor in learning sciences asked graduate students to serve as informants on student experience with ebooks. In two semester-long studies we analyzed student work, focusing on barriers and affordances they identified. In the first cohort, students who chose to explore ebooks uncovered affordances. In the second cohort, student comfort levels with PDF formats increased, while comfort with ebooks decreased. We discuss strategies for minimizing challenges and increasing desirable difficulties to support ebooks as …
