Description
Incidental learning of sequential information occurs in visual, auditory and tactile domains. It occurs throughout our lifetime and even in nonhuman species. It is likely to be one of the most important foundations for the development of normal learning. To date, there is no agreement as to how incidental learning occurs. The goal of the present set of experiments is to determine if visual sequential information is learned in terms of abstract rules or stimulus-specific details. Two experiments test the extent to which interaction with the stimuli can influence the information that is encoded by the learner. The results of both experiments support the claim that stimulus and domain specific details directly shape what is learned, through a process of tuning the neuromuscular systems involved in the interaction between the learner and the materials.

Description
The aim of this study was to examine the influence of Assisted Cycling Therapy (ACT) on information processing measured by simple reaction time in older adults with Down Syndrome (DS). Twenty-one participants were randomly assigned to one of three interventions over eight weeks. 1) Eleven older adults with Down Syndrome completed the ACT intervention, which is stationary cycling with the assistance of a motor to maintain a cadence at least 35% greater than voluntary cycling. 2) Eight older adults with Down Syndrome completed the voluntary cycling (VC) intervention and 3) two older adults with Down Syndrome were in our no cycling (NC) intervention. Both exercise groups participated in the eight-week, supervised exercise protocol for at least three, 30-minute sessions per week. None of our results reached conventional levels of significance. However, the greatest improvements in reaction time occurred following the voluntary cycling (VC) intervention. Our results are discussed with respect to physiological differences in older adults with DS that may limit improvements in executive function following exercise. These physiological differences and limitations include muscle atrophy and reduced perceptions, age related latency between motor cortex activation and onset of muscle activity, as well as general age related slowing in reaction time. Although it may be difficult to improve executive function in older adults with DS, we suggest other benefits to exercise which include improving social communication, gross motor skills, and exercise perception. Future research should continue to investigate the effects of exercise on multiple areas in older adults with DS with the hopes of improving quality of life.

Description
The aim of this study was to examine the effects of Assisted Cycle Therapy (ACT) on self-efficacy and exercise perception in older adults with Down syndrome (DS) after a three times a week for 8 weeks intervention. Thirteen participants were in the ACT group in which a motor assisted their cycling to be performed at least 30% faster than voluntary cycling (VC), 11 participants were in the voluntary cycling group and two participants were in the no cycling (NC) group. The results showed that both exercise groups (i.e., ACT and VC) improved in their self-efficacy after the 8 week intervention. In addition, exercise perception improved following ACT and not VC or NC. Our results are discussed with respect to their future implications for exercise in the DS population. It might be that the yielded results were due to differences in effort required by each intervention group as well as the neurotrophic factors that occur when muscle contractions create synaptic connections resulting in improvement in cognition and feelings of satisfaction. In the future, research should focus on the psychological factors such as social accountability and peer interaction as they relate to ACT and physical activity in person's with DS.

Description
Education is a fundamental human right. However, when groups of people are subjugated to systematic violence and institutionalization, the importance of education often is often forgotten. A team of students and faculty at Arizona State University (ASU) currently teach an Introduction to Psychology course within a minimum-security unit in conjunction with both the Arizona Department of Corrections and the Prison Education Program at ASU. This course aims to enhance the current educational programs offered by the prison by fostering an environment where inmates can practice literacy skills and are introduced to standard classroom procedures for the typical university class. In addition, the course introduces students to an academic field previously unknown to them, specifically, psychology. However, the most important aspect of this educational endeavor is to provide an environment where people who have been deemed inhuman and outside of the human experience can come together and learn. By doing so, the curriculum sought to instill confidence in the students by demonstrating that they are in fact capable of learning and comprehending university level material. As of 2016, numerous studies have been conducted from across the nation that have reaffirmed the validity and efficacy of prison education on reducing recidivism levels of the previously incarcerated (ADC 2005, Kim & Clark 2013, Nuttal et al. 2003). Additionally, studies have determined that the benefits that students receive from education while incarcerated are, over time, shared with the family members (Erisman & Contardo, 2005). These benefits, while not strictly educational, are incredibly important within the realm of reduction in crime as they pertain to "reduction of costs, reduction of strain of offenders on their families, and an economic boost for society" (Erisman & Contardo, 2005). Teaching within any prison unit, regardless of the security level, provides a variety of unique challenges. Some of these include the lack of technological resources within most classrooms, prohibition of outside material unless vetted and approved by prison education staff, and rigid restrictions on student-teacher interactions. Also, because of the nature of psychology and the students within the class, certain sensitive topics must be either handled with extreme care or will not be covered at all. However, particular achievements were made in regards to increasing in class participation and encouraging the students to continue to pursue academics. Most importantly, it provides an environment where the humanity of the prisoner is restored, if but for only a few hours a week. It allows them to be seen as more than numbers, allows them to think and voice their opinions in a space that respects them for their beliefs. And the restoration of humanity to an inherently inhumane system is far more important than any other educational goal.

Description
The human body is a complex system comprised of many parts that can coordinate in a variety of ways to produce controlled action. This creates a challenge for researchers and clinicians in the treatment of variability in motor control. The current study aims at testing the utility of a nonlinear analysis measure – the Largest Lyapunov exponent (1) – in a whole body movement. Experiment 1 examined this measure, in comparison to traditional linear measure (standard deviation), by having participants perform a sit-to-stand (STS) task on platforms that were either stable or unstable. Results supported the notion that the Lyapunov measure characterized controlled/stable movement across the body more accurately than the traditional standard deviation (SD) measure. Experiment 2 tested this analysis further by presenting participants with an auditory perturbation during performance of the same STS task. Results showed that both the Lyapunov and SD measures failed to detect the perturbation. However, the auditory perturbation may not have been an appropriate perturbation. Limitations of Experiment 2 are discussed, as well as directions for future study.
