Chickens Play To The Crowd, Cinzia Chiandetti
Animal Sentience
The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.

Early Contributions To Infants’ Mental Rotation Abilities, Mihaela Constantinescu, David S. Moore, Scott P. Johnson, Melissa Hines
Pitzer Faculty Publications and Research
Some cognitive abilities exhibit reliable gender differences, with females outperforming males in specific aspects of verbal ability, and males showing an advantage on certain spatial tasks. Among these cognitive gender differences, differences in mental rotation are the most robust, and appear to be present even in infants. A large body of animal research suggests that gonadal hormones, particularly testosterone, during early development could contribute to this gender difference in mental rotation. Also, substantial evidence supports an influence of socialization on mental rotation performance. The present study investigated the relationship of two types of factors, early postnatal testosterone exposure and parental …

The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, John E. Kiat, Michael D. Dodd, Robert F. Belli, Jacob E. Cheadle
Department of Psychology: Faculty Publications
Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected …

Overt And Covert Attention In Infants Revealed Using Steady-State Visually Evoked Potentials, Joan Christodoulou, David S. Leland, David S. Moore
Pitzer Faculty Publications and Research
Although looking-time methods have long been used to measure infant attention and investigate aspects of cognitive development, steady-state visually evoked potential (SSVEP) measures may be more sensitive or practical in some contexts. Here, we demonstrate habituation of infants’ SSVEP amplitudes to a flickering checkerboard stimulus, and recovery of attention upon presentation of a novel checkerboard stimulus. This modulation of SSVEP amplitude was more robust than the modulation of looking time. In addition, we provide evidence of enhanced SSVEPs in response to covertly attended checkerboards flickering in peripheral visual fields, even while infants are fixating a central stimulus. These experiments provide …
The Impact Of Neonatal Pain And Reduced Maternal Care On Brain And Behavioral Development,

The Impact Of Neonatal Pain And Reduced Maternal Care On Brain And Behavioral Development, Sean Michael Mooney-Leber
Wayne State University Dissertations
In the neonatal intensive care unit (NICU) preterm infants are exposed to a multitude of stressors, which include both neonatal pain and reduced maternal care. Clinical and preclinical research has demonstrated that exposure to neonatal pain and reduced maternal care has a profound negative impact on brain and behavioral development. Currently, the biological mechanism by which both of these stressors impacts brain and behavioral outcomes remains widely unknown. To uncover a potential biological mechanism, the current dissertation project utilized a preclinical model of repetitive needle pokes and developed a novel model of reduced maternal care through tea-ball encapsulation. Briefly, rat …

Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur
Jeffrey Stevens Publications
Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions or with actions from previous …

Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers
Theses and Dissertations
Anxiety disorders (ADs) and stress-related disorders are some of the most common psychiatric disorders in the United States. Like other c0mplex psychiatric illness, genetics and neuroimaging research has focused on understanding their underlying neurobiology. Areas within the fear-network play important roles in threat perception, fear conditioning/learning, cognitive processing, and modulation of fear responses including contextual modulation and extinction and have been implicated in ADs as well as stress disorders such as posttraumatic stress disorder (PTSD). The primary gap in the current search for underlying biological mechanisms is in whether biomarkers associated with disorders share genetic influences with the disorders they …

Occupational Health Psychology, Irvin Sam Schonfeld
Publications and Research
Occupational health psychology (OHP) is a cross-disciplinary subspecialty within psychology. OHP derives from two disciplines within applied psychology, health psychology and industrial/organizational psychology. OHP is also linked to disciplines outside of psychology, such as occupational medicine and public health. The discipline has roots in eighteenth, nineteenth, and twentieth century thinkers, including Adam Smith, Friedrich Engels, Karl Marx, Émile Durkheim, and Max Weber. These thinkers were concerned with the impact of the organization of work and the business cycle on human life. Later research by Elton Mayo, Marie Jahoda, Walter B. Cannon, Hans Selye, and investigators at the University of Michigan’s …

Despite literature revealing the adverse consequences of objectifying gazes for women, little work has empirically examined origins of objectifying gazes by perceivers. Integrating alcohol myopia and objectification theories, we examined the effects of alcohol as well as perceived female attractiveness, warmth, and competence on objectifying gazes. Specifically, male undergraduates (n = 49) from a large U.S. Midwestern university were administered either an alcoholic or placebo beverage. After consumption, participants were asked to focus on the appearance or personality (counterbalanced) of pictured women who were previously rated as high, average, or low in attractiveness, warmth, and competence. Replicating previous work, appearance …

The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton
Theses and Dissertations--Psychology
Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Modeling The Psychiatric Aspects Of Polycystic Ovary Syndrome And Induced Stress, Danielle Peecher
All Master's Theses
Polycystic ovary syndrome (PCOS) is an endocrine disorder in women that is characterized by excess testosterone and is associated with increased risk of infertility. Women with PCOS also show higher rates of depression and anxiety. Modeling PCOS in mice via administration of dihydrotestosterone (DHT) results in physiological alterations that are consistent with the physiological symptoms of PCOS in women. While some studies have investigated behavioral changes in PCOS mouse models, findings have varied. Thus, the current research examined whether a PCOS model with an additional stress factor resulted in behavioral changes. To create a stress condition, subjects were implanted with …

Cal Poly Humboldt theses and projects
Brain health, and the benefits of exercise have been linked to the biological signaling molecule called brain-derived neurotrophic factor (BDNF). Animal and human studies have provided some support for physical exercise as a mechanism for increasing BDNF levels. However, results have been inconsistent, which may be attributed in part to incomplete information about normal variation in circulating peripheral BDNF levels. This investigation examined capillary-drawn whole blood samples from nine healthy adult participants over 30 days with the goal of documenting variability in resting BDNF levels and changes that may be attributed to physical exercise. It was hypothesized that BDNF concentrations …

One factor influencing organismal longevity is the activity of transcription factors of the “fork head domain” family, otherwise known as “Forkhead box” (Fox) proteins. Studies of the four isoforms of the “O” subclass of Fox proteins found in human genes have revealed a direct relationship between FoxO3a-dependent gene expression and the conservation of neural stem cell (NSC) in the adult brain, specifically in the subgranular zone of the dentate gyrus in the hippocampus and the subventricular zone of the cortex. This transcription factor has also been shown to regulate apoptosis in nervous tissue during embryonic development in zebrafish. The current …

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …

Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …

Do Different Music Genres Differentially Affect Autonomic Activity? How Music And Sound Affect Autonomic Activity Aroused By Visual Stimuli, Andrew Manson
Online Theses and Dissertations
The primary researcher sought to determine whether different genres of music would differentially influence measures of autonomic nervous system activity (heart rate, galvanic skin response) while viewing visual stimuli in a sample of college students. All participants listened to the same songs and music genres and viewed the same International Affective Picture System (IAPS) images. Autonomic nervous system activity was recorded by attaching electrodes to participants' non-dominant hand and torso. Music order presentation and picture order presentation were randomly determined by E-Prime. Heart rate and skin conductance responses were both significant, with melodic metal music inducing greater intensity of responses …

Investigating The Roles Of Mechanoreceptive Channels In Tactile Apparent Motion Perception: A Vibrotactile Study, Phill Kim, Philip Servos Dr.
Theses and Dissertations (Comprehensive)
Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this. The current study focused on the Rapidly Adapting (RA) channel and Slowly Adapting I (SAI) channel on the index finger. The experiment implemented vibrotactile masking stimuli to target the mechanoreceptive channels with the goal of gaining better insight into the involvement of mechanoreceptive channels in the perception of TAM. Masking stimuli were used because previous studies have used them to differentiate between different channels; a …

Making Smart Choices When Faced With Risk: The Role Of Interoceptive Awareness And Life Stress On Implicit Learning., Ronald A. Nicholson
Dissertations and Theses
In complex situations where there is an unclear link between the available options and an advantageous outcome, visceral signals of arousal play a role in decision-making. Perception of the body’s various visceral signals is called interoceptive awareness (IA). Exposure to stressful events can impede the production and perception of these signals, leading to a potentially impaired perception of risk and impeded decision-making. However, there is a paucity of research exploring the impact of life event stress on IA, or how both of these factors may influence the dynamic process of decision-making during risk. To address this gap the current study …

Epigenetic mechanisms result in persistent changes at the cellular level that can lead to long-lasting behavioral adaptations. Nucleosome remodeling is a major epigenetic mechanism that has not been well explored with regards to drug-seeking behaviors. Nucleosome remodeling is performed by multi-subunit complexes that interact with DNA or chromatin structure and possess an ATP-dependent enzyme to disrupt nucleosome-DNA contacts and ultimately regulate gene expression. Calcium responsive transactivator (CREST) is a transcriptional activator that interacts with enzymes involved in both histone acetylation and nucleosome remodeling. Here, we examined the effects of knocking down CREST in the nucleus accumbens (NAc) core on drug-seeking …
