Diurnally Active Rodents For Laboratory Research, Roberto Refinetti, G. J. Kenagy

Psychological Sciences Faculty Publications and Presentations

Although inbred domesticated strains of rats and mice serve as traditional mammalian animal models in biomedical research, the nocturnal habits of these rodents make them inappropriate for research that requires a model with human-like diurnal activity rhythms. We conducted a literature review and recorded locomotor activity data from four rodent species that are generally considered to be diurnally active, the Mongolian gerbil (Meriones unguiculatus), the degu (Octodon degus), the African (Nile) grass rat (Arvicanthis niloticus), and the antelope ground squirrel (Ammospermophilus leucurus). Our data collected under 12L:12D light-dark cycles confirmed and expanded …

Motivational Valence Alters Memory Formation Without Altering Exploration Of A Real-Life Spatial Environment, Kimberly S. Chiew, Jordan Hashemi, Lee K. Gans, Laura Lerebours, Nathaniel J. Clement, Mai-Anh T. Vu, Guillermo Sapiro, Nicole E. Heller, R. Alison Adcock

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 …

The Relationship Between Exposure To Lead And Criminal Behavior, Margaret Meyer, Christine Rogers

2017-2018: Scott County, Iowa Health Department

In recent years it has been made apparent that exposure to lead is a significant problem for many individuals and families. Lead exposure–whether through the air, water, or by ingestion–has been linked to numerous physical, cognitive, and social problems (Chandramouli, 2009; Nevin, 2007). Furthermore, urban, poor and immigrant populations are at a higher risk for lead exposure (Bakhireva, et al., 2013). And increasingly a connection between lead exposure and criminal behavior has been identified through both correlation studies and experiments. The high cost of exposure to lead is apparent when looking at the effects of lead over a lifetime, and …

The Impact Of Chronic Stress, Traumatic Experiences And Genes On Behavior, Colten Brown

Research on Capitol Hill

Chronic unpredictable stress (CUS) alters neurotransmission and remodels neural circuits involved in learning, attention and decision making.

Glial-derived neurotrophic factor (GDNF) is essential for the function of neurons. Regulation of GDNF during stress is linked to resiliency while the inability to regulate it causes behavioral alterations.

We investigated the effects of CUS on latent inhibition (LI), a measure of selective attention expressed in this model as freezing behavior.

Normal Behavioral Responses To Light And Darkness And The Pupillary Light Reflex Are Dependent Upon The Olivary Pretectal Nucleus In The Diurnal Nile Grass Rat, Andrew J. Gall, Ohanes S. Khacherian, Brandi Ledbetter, Sean P. Deats, Megan Luck, Laura Smale, Lily Yan, Antonio A. Nunez

Faculty Publications

The olivary pretectal nucleus (OPT) is a midbrain structure that receives reciprocal bilateral retinal projections, is involved in the pupillary light reflex, and connects reciprocally with the intergeniculate leaflet (IGL), a retinorecipient brain region that mediates behavioral responses to light pulses (i.e., masking) in diurnal Nile grass rats. Here, we lesioned the OPT and evaluated behavioral responses in grass rats to various lighting conditions, as well as their anxiety-like responses to light exposure. While control grass rats remained diurnal, grass rats with OPT lesions exhibited a more night-active pattern under 12h:12h light-dark (LD) conditions. However, when placed in constant darkness, …

A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko

Senior Honors Projects

Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a …

Adolescent Cannabinoid Exposure Induces A Persistent Sub-Cortical Hyper-Dopaminergic State And Associated Molecular Adaptations In The Prefrontal Cortex., Justine Renard, Laura G Rosen, Michael Loureiro, Cleusa De Oliveira, Susanne Schmid, Walter J Rushlow, Steven R Laviolette

Brain and Mind Institute Researchers' Publications

Considerable evidence suggests that adolescent exposure to delta-9-tetrahydrocanabinol (THC), the psychoactive component in marijuana, increases the risk of developing schizophrenia-related symptoms in early adulthood. In the present study, we used a combination of behavioral and molecular analyses with in vivo neuronal electrophysiology to compare the long-term effects of adolescent versus adulthood THC exposure in rats. We report that adolescent, but not adult, THC exposure induces long-term neuropsychiatric-like phenotypes similar to those observed in clinical populations. Thus, adolescent THC exposure induced behavioral abnormalities resembling positive and negative schizophrenia-related endophenotypes and a state of neuronal hyperactivity in the mesocorticolimbic dopamine (DA) pathway. …

Origins Of Thalamic And Cortical Projections To The Posterior Auditory Field In Congenitally Deaf Cats., Blake E Butler, Nicole Chabot, Andrej Kral, Stephen G Lomber

Psychology Publications

Crossmodal plasticity takes place following sensory loss, such that areas that normally process the missing modality are reorganized to provide compensatory function in the remaining sensory systems. For example, congenitally deaf cats outperform normal hearing animals on localization of visual stimuli presented in the periphery, and this advantage has been shown to be mediated by the posterior auditory field (PAF). In order to determine the nature of the anatomical differences that underlie this phenomenon, we injected a retrograde tracer into PAF of congenitally deaf animals and quantified the thalamic and cortical projections to this field. The pattern of projections from …

Marine Mammal Behavior: A Review Of Conservation Implications, Philippa Brakes, Sasha R. X. Dall

Social Behavior Collection

The three orders which comprise the extant marine mammals exhibit a wide range of behaviors, varying social structures, and differences in social information use. Human impacts on marine mammals and their environments are ubiquitous; from chemical and noise pollution, to marine debris, prey depletion, and ocean acidification. As a result, no marine mammal populations remain entirely unaffected by human activities. Conservation may be hindered by an inadequate understanding of the behavioral ecology of some of these species. As a result of social structure, social information use, culture, and even behavioral syndromes, marine mammal social groups, and populations can be behaviorally …

Impacts Of Music On Sectional View Drawing Ability For Engineering Technology Students As Measured Through Technical Drawings, Petros J. Katsioloudis, Mildred Jones, Vukica Jovanovic

STEMPS Faculty Publications

Results from a number of studies indicate that the use of different types of music can influence cognition and behavior; however, research provides inconsistent results. Considering this, a quasi-experimental study was conducted to identify the existence of statistically significant effects on sectional view drawing ability due to the impacts of music. In particular, the study compared the use of three different types of music; classical, rock, heavy metal and whether a significant difference exists towards sectional view drawing ability, among engineering technology students. According to the results of this study it is suggested that the impact of music provides no …

Enriching Cultural Psychology With Research Insights On Norms And Intersubjective Representations, Xi Zou, Angela K. Y. Leung

Research Collection School of Social Sciences

Norms are one of the most important yet least understood processes influencing social behavior.Since the seminal work of Kurt Lewin (1943), social norms have been widely studied in socialpsychology research, contributing to studies on attitude–behavior relations (e.g., Ajzen, 1991),social influence (e.g., Deutsch & Gerard, 1955), social control (e.g., Ajzen & Madden, 1986;Bandura, 1977), group decision making (e.g., Janis, 1972; Longley & Pruitt, 1980), conformity(e.g., Asch, 1951; Sherif, 1936), and stereotypes (e.g., Schaller & Latané, 1996; Stangor, Sechrist,& Jost, 2001). The goal of this Special Issue is to capture the latest wave of research discoverieson the role of norms in understanding …

Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet

Research Collection School of Social Sciences

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that …

Contrasting Styles In Cognition And Behaviour In Bumblebees And Honeybees., David F Sherry, Caroline G Strang

Psychology Publications

Bumblebees and honeybees have been the subjects of a great deal of recent research in animal cognition. Many of the major topics in cognition, including memory, attention, concept learning, numerosity, spatial cognition, timing, social learning, and metacognition have been examined in bumblebees, honeybees, or both. Although bumblebees and honeybees are very closely related, they also differ in important ways, including social organization, development, and foraging behaviour. We examine whether differences between bumblebees and honeybees in cognitive processes are related to differences in their natural history and behaviour. There are differences in some cognitive traits, such as serial reversal learning and …

The Effects Of Varied Opportunities To Respond Embedded In A Group Contingency Program, Teresa Donna Bolt

Student Works

This study investigated the effects of using a group contingency program with three students with disabilities in a small group special education setting. These students exhibited both academic and behavioral difficulties. With the use of Class Wide Function-Related Intervention Team (CW-FIT) students increased their active engagement and correct responses, as well as decreased their disruptive behaviors; however, these behaviors did not maintain over time. CW-FIT with high opportunities to respond showed an even greater improvement than CW-FIT with low opportunities to respond. Increased opportunities to respond resulted in higher levels of active engagement and correct responses and decreases in disruptive …

Decoding The Neural Circuitry Of Reward Behavior, Ernesto H. Bedoy, James M. Hyman

McNair Poster Presentations

Classical conditioning demonstrates that rewards can be used to train behavior by pairing a stimulus, known as a prompt, with reinforced behavior. At a neuronal level, this association strengthens the connections between the neurons involved, making communication easier the next time. Enhanced communication is identified with learning, allowing an organism to anticipate a reward with a prompt so that it can perform the desired behavior to successfully obtain the reward (Noonan et al., 2011). In this study, we created a computational model to represent a neural circuit with synaptic plasticity during reward, no-reward and anticipation states. Our results confirmed our …

Pupil Dilation Dynamics Track Attention To High-Level Information, Olivia E. Kang, Katherine E. Huffer, Thalia P. Wheatley

Dartmouth Scholarship

It has long been thought that the eyes index the inner workings of the mind. Consistent with this intuition, empirical research has demonstrated that pupils dilate as a consequence of attentional effort. Recently, Smallwood et al. (2011) demonstrated that pupil dilations not only provide an index of overall attentional effort, but are time-locked to stimulus changes during attention (but not during mind-wandering). This finding suggests that pupil dilations afford a dynamic readout of conscious information processing. However, because stimulus onsets in their study involved shifts in luminance as well as information, they could not determine whether this coupling of stimulus …

Preference-Based Serial Decision Dynamics: Your First Sushi Reveals Your Eating Order At The Sushi Table, Jaeseung Jeong, Youngmin Oh, Miriam Chun, Jerald D. Kralik

Dartmouth Scholarship

In everyday life, we regularly choose among multiple items serially such as playing music in a playlist or determining priorities in a to-do list. However, our behavioral strategy to determine the order of choice is poorly understood. Here we defined ‘the sushi problem’ as how we serially choose multiple items of different degrees of preference when multiple sequences are possible, and no particular order is necessarily better than another, given that all items will eventually be chosen. In the current study, participants selected seven sushi pieces sequentially at the lunch table, and we examined the relationship between eating order and …

Growing Ideas - Daily Transitions - Time For A Change, University Of Maine Center For Community Inclusion And Disability Studies

Early Childhood Resources

Young children with and without disabilities experience many changes during their day. Daily transitions in early care and education programs take place during an activity, or when children move from one activity to another or one location to another. Transitions include the following: Arriving at or departing from a program; Exchanging toys; Entering or leaving a play area during free choice time; Cleaning up after morning activities and starting a group circle time; Getting dressed to go outside to play; and Shifting from playing with friends to working with a teacher/therapist on a particular skill. Thoughtful planning is needed so …

Academic Predictors And Characteristics Of Self-Reported Juvenile Firesetting, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

The main purpose of this study was to address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Logistic regressions were run to determine if attention problems predicted firesetting and the findings indicated that attention problems are predictive …

An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli

Psychology Faculty Research and Publications

Recently research on the relationship between stress and cognition, emotion, and behavior has greatly increased. These advances have yielded insights into important questions ranging from the nature of stress' influence on addiction1 to the role of stress in neural changes associated with alterations in decision-making^2,3. As topics being examined by the field evolve, however, so too must the methodologies involved. In this article a practical and effective alternative to a classic stress induction technique, the cold pressor test (CPT), is presented: the cold pressor arm wrap (CPAW). CPT typically involves immersion of a participant's dominant hand in ice-cold …

Caffeinated Alcohol Use And Expectancies For Caffeine Versus Alcohol, Cathy Lau-Barraco, Ashley N. Linden

A Study Of How Selected Public School Junior-High Students Perceive The Effect Of Popular Music On Classroom Behavior, Christopher Mc Allister

Masters Theses

The objective of this study is to further the understanding of how junior-high students in the public schools perceive the effects of popular music on their behavior in the classroom. Two primary research questions serve as the foundation for this study. The first question investigates how themes disclosed in interviews of selected public school junior high students help to explain their personal perceptions of how popular music affects their behavior in the academic environment. The second question seeks to determine whether students that listen to a particular genre of popular music have different or similar perceptions of how music affects …

Skill Learning Strengthens Cortical Representations Of Motor Sequences., Tobias Wiestler, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Motor-skill learning can be accompanied by both increases and decreases in brain activity. Increases may indicate neural recruitment, while decreases may imply that a region became unimportant or developed a more efficient representation of the skill. These overlapping mechanisms make interpreting learning-related changes of spatially averaged activity difficult. Here we show that motor-skill acquisition is associated with the emergence of highly distinguishable activity patterns for trained movement sequences, in the absence of average activity increases. During functional magnetic resonance imaging, participants produced either four trained or four untrained finger sequences. Using multivariate pattern analysis, both untrained and trained sequences could …

A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson

Faculty Scholarship for the College of Science & Mathematics

This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles and practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention toward one's health, while acknowledging the spiritual aspects of one's nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness …
