Birds Of A Feather: Exploring Social Facilitation Effects On Learning And Suboptimal Choice In Pigeons (Columba Livia), Peyton Mueller
Birds Of A Feather: Exploring Social Facilitation Effects On Learning And Suboptimal Choice In Pigeons (Columba Livia), Peyton Mueller
Theses and Dissertations--Psychology
The social facilitation effect describes a change in the behavior of an individual due to the presence of another organism of the same species (i.e., a conspecific). Many theories exist that attempt to explain why this change in behavior exists across species. A set of four experiments were executed to best explain how pigeons learn in the presence of non-competing conspecifics. The first experiment sought to replicate an interesting effect previously found in cockroaches and rats, such that conspecific presence inhibits performance early in training but facilitates it with increased training. The second experiment placed the novel response acquired in …
Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra
Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra
Undergraduate Student Research Internships Conference
The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.4 Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.1 Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).2 Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like …
Individual Differences In Structure Learning, Philip Newlin
Individual Differences In Structure Learning, Philip Newlin
Theses and Dissertations
Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …
Examining The Relationship Between Confusion And Learning: A Descriptive Meta-Analysis, Dara L. Mcweeney, Aaron Y. Wong, Caitlin Mills
Examining The Relationship Between Confusion And Learning: A Descriptive Meta-Analysis, Dara L. Mcweeney, Aaron Y. Wong, Caitlin Mills
Honors Theses and Capstones
Previous research into confusion and learning neglects to investigate how this relationship varies when faced with impact factors such as multiple types of affect and learning measurements, learning environment, or grade level. Moreover, past research also reports di-verse effect size values for this relationship, making the correlation ambiguous. As such, the current research seeks to reconcile these nuances between confusion and learning through a meta-analytic approach. In this analysis, it was found that there was no relationship between confusion and learning gains, or in the subgroup analysis of grade level. Since only one impact factor, grade level, was analyzed, it …

Psychology: Faculty Scholarship
Volitional exploration and learning are key to adaptive behavior, yet their characterization remains a complex problem for cognitive science. Exploration has been posited as a mechanism by which motivation promotes memory, but this relationship is not well-understood, in part because novel stimuli that motivate exploration also reliably elicit changes in neuromodulatory brain systems that directly alter memory formation, via effects on neural plasticity. To deconfound interrelationships between motivation, exploration, and memory formation we manipulated motivational state prior to entering a spatial context, measured exploratory responses to the context and novel stimuli within it, and then examined motivation and exploration as …
