Fallow Bucks Attend To Vocal Cues Of Motivation And Fatigue, Benjamin J. Pitcher, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott

Sentience Collection

Vocalizations encode a range of information about the caller, and variation in calling behavior and vocal structure may provide listeners with information about the motivation and condition of the caller. Fallow bucks only vocalize during the breeding season and can produce more than 3000 groans per hour. Males modulate their calling rates, calling faster when other calling males and/or females are nearby. Groans also reveal caller fatigue, becoming shorter and higher pitched toward the end of the rut. Thus, fallow deer groans vary both over very short (minute to minute) and longer timescales (the rut). However, no studies have investigated …

Learning And Memory In The Port Jackson Shark, Heterodontus Portusjacksoni, Tristan L. Guttridge, Culum Brown

Sentience Collection

Basic understanding of the fundamental principles and mechanisms involved in learning is lacking for elasmobranch fishes. Our aim in this study was to experimentally investigate the learning and memory capacity of juvenile Port Jackson sharks, Heterodontus portusjacksoni. Sharks (N = 30) were conditioned over a 19-day period to associate an underwater LED light or stream of air-bubbles [conditioned stimulus (CS)] with a food reward [unconditioned stimulus (US)], using three procedures (delay, trace and control). During experiments, the CS signalled at a random time between 180 and 300 s for 30 s (six times per day). For the delay the US …

Levels Of Altruism, Martin Zwick, Jeffrey Alan Fletcher

Complex Systems Faculty Publications and Presentations

The phenomenon of altruism extends from the biological realm to the human socio-cultural realm. This paper sketches a coherent outline of multiple types of altruism of progressively increasing scope that span these two realms and are grounded in an ever-expanding sense of"self." Discussion of this framework notes difficulties associated with altruisms at different levels. It links scientific ideas about the evolution of cooperation and about hierarchical order to perennial philosophical and religious concerns. It offers a conceptual background for inquiry into societal challenges that call for altruistic behavior, especially the challenge of environmental and social sustainability.

Stress-Dependent Opioid And Adrenergic Modulation Of Newly Retrieved Fear Memory, Allen M. Schneider, Peter E. Simson , '78, Caitlin M. Daimon , '11, Jakob Mrozewski , '11, Nicholas M. Vogt , '12, John R. Keefe , '10, Lynn G. Kirby , '89

Psychology Faculty Works

Recent studies on the effect of stress on modulation of fear memory in our laboratory have uncovered endogenous opioid and adrenergic based modulation systems, working in concert, that limit the strengthening or weakening of newly acquired fear memory during consolidation under conditions of mild or intense stress, respectively. The present study sought to determine if similar stress-dependent modulation, mediated by endogenous opioid and adrenergic systems, occurs during reconsolidation of newly retrieved fear memory. Rats underwent contextual fear conditioning followed 24 h later by reactivation of fear memory; a retention test was administered the next day. Stress was manipulated by varying …

Gender Identity, Ethnic Identity, And Self-Esteem In Latino Adolescent Males, Miriam Asya Reder

Master's Theses

The relationship between gender identity and psychological adjustment has long been investigated, but it is only in the 21^st century that gender identity has been examined as a multi-faceted construct. According to Egan and Perry (2001), there are five dimensions comprising a person’s gender identity and they have demonstrated a significant relationship between these dimensions and youth’s psychological adjustment. Three of their gender identity constructs are pertinent to this study: gender typicality, gender contentedness, and felt pressure. While subsequent studies have had similar significant results (Carver, Yunger, & Perry, 2003; Yunger, Carver, & Perry, 2004), one study found that …

Parenting Styles And Adjustment Outcomes Among College Students, Keisha M. Love, Deneia M. Thomas

Educational, School, and Counseling Psychology Faculty Publications

Research has demonstrated that parenting styles partially explain college students’ academic adjustment. However, to account for academic adjustment more fully, additional contributors should be identified and tested. We examined the fit of a hypothesized model consisting of parenting styles, indicators of well-being, and academic adjustment among 315 college students. The model demonstrated a close fit to the data and contained several significant paths.

Family Incivility And Job Performance: A Moderated Mediated Model Of Psychological Distress And Core Self-Evaluation, Sandy Lim, Kenneth Tai

Research Collection Lee Kong Chian School Of Business

This study extends the stress literature by exploring the relationship between family incivility and job performance. We examine whether psychological distress mediates the link between family incivility and job performance. We also investigate how core self-evaluation might moderate this mediated relationship. Data from a 2-wave study indicate that psychological distress mediates the relationship between family incivility and job performance. In addition, core self-evaluation moderates the relationship between family incivility and psychological distress but not the relationship between psychological distress and job performance. The results hold while controlling for general job stress, family-to-work conflict, and work-to-family conflict. The findings suggest that …

Judging A Man By The Width Of His Face: The Role Of Facial Ratios And Dominance In Mate Choice At Speed-Dating Events, Katherine A. Valentine, Norman P. Li, Lars Penke, David I. Perrett

Research Collection School of Social Sciences

Previous research shows that men with higher facial width-to-height ratios (fWHRs) have higher testosterone, are more aggressive, more powerful, and more financially successful, but are they more attractive to women in an ecologically valid mating context, speed-dating? Male fWHR was positively associated with perceptions of dominance, being chosen for a second date, and attractiveness to women for short-term, but not long-term relationships. Perceived dominance mediated (by itself and through physical attractiveness) the relationship between fWHR and women’s interest in short-term relationships. Furthermore, men’s perceptions of own dominance reflected patterns in mating desirability similar to those of fWHR. These results support …

Muscle Tension Induced After Learning Enhances Long-Term Narrative And Visual Memory In Healthy Older Adults, Kristy A. Nielson, Laura L. Wulff, Timothy J. Arentsen

Psychology Faculty Research and Publications

Arousing events are better remembered than mundane events. Indeed, manipulation of arousal, such as by muscle tension, can influence memory even when it occurs shortly after learning. Indeed, our founding study showed this approach can raise delayed memory performance in older adults to a level comparable to that of unaided young adults. Yet, systematic studies, especially those investigating different modalities or types of memory, have not been done. This study investigated the effects of a brief bout of isometric exercise via handgrip on narrative and visuospatial episodic memory in healthy elders. Forty-seven participants completed the Logical Memory subtest of the …

An Asymmetry In Shape And Shape Word Interference: Evidence For Core Geometric Knowledge, Joshua E. Edwards, Ty W. Boyer, Bradley R. Sturz

Psychology: Faculty Presentations (2009-2022)

Nativists have postulated fundamental geometric knowledge that predates linguistic and symbolic thought. Central to these claims is the existence of an isolated cognitive system dedicated to processing geometric information. Testing such hypotheses presents challenges due to difficulties in eliminating the combination of geometric and non-geometric information through language. We present evidence using a modified matching interference paradigm that an incongruent shape word interferes with identifying a shape, but an incongruent shape does not interfere with identifying a shape word. This asymmetry in shape and shape word interference suggests that shape words activate spatial representations of shapes but shapes do not …

Orientation Via Enclosure Geometry By Blind-Folded Adults: Evidence Against View-Based Matching Theories Of Spatial Orientation, Marshall L. Green, Katherine A. Gaskin, Jonathan E. Roberts, Bradley R. Sturz

Psychology: Faculty Presentations (2009-2022)

Although spatial orientation via geometric properties of an environment is an ability shared across species, debate remains concerning similarities and differences in the underlying mechanism(s). One theoretical account of spatial orientation suggests that participants match visual memories to current visual perception and navigate to reduce discrepancy between the two. We tested a view-based matching account of spatial orientation by training disoriented and blind-folded human participants to search by touch for a target object hidden in one of four locations marked by distinctive textural cues located in the corners of a rectangular enclosure. Following training, we removed the distinctive textural cues …

An Exploration Of Early Childhood Attachment In A Sample Of Christian Men Experiencing Same-Sex Attraction, Ann Gillies

Doctoral Dissertations and Projects

The purpose of the study was to describe the attachment histories of these men in an attempt to hear the lived experiences from the voices of the men themselves. The Adult Attachment Interview (AAI) was utilized, followed by several in-depth questions. A phenomenological analysis of the transcripts revealed several themes.

The AAI themes were identified as Insecure attachment: (a) Unresolved/disorganized (U/d) due to loss; (b) Passively Preoccupied (E) with a rejecting/neglecting father and an involving/rejecting mother. Secondary themes of abuse and peer rejection were also identified. The themes of a neglecting father and over-involved mother were collaborated in the in-depth …

Variable Temporoinsular Cortex Neuroanatomy In Primates Suggests A Bottleneck Effect In Eastern Gorillas, S. K. Barks, A. L. Bauernfeind, C. J. Bonar, M. R. Cranfield, A. A. De Sousa, J. M. Erwin, William D. Hopkins, A. H. Lewandowski, A. Mudakikwa, Kimberley A. Phillips, Mary Ann Raghanti, Cheryl D. Stimpson, Patrick R. Hof, K. Zilles, Chet C. Sherwood

Psychology Faculty Research

We describe an atypical neuroanatomical feature present in several primate species that involves a fusion between the temporal lobe (often including Heschl's gyrus in great apes) and the posterior dorsal insula, such that a portion of insular cortex forms an isolated pocket medial to the Sylvian fissure. We assessed the frequency of this fusion in 56 primate species (including apes, Old World monkeys, New World monkeys, and strepsirrhines) by using either magnetic resonance images or histological sections. A fusion between temporal cortex and posterior insula was present in 22 species (seven apes, two Old World monkeys, four New World monkeys, …

The Quantified Self, Behind The Cover Art, Leslie Love Stone

The Transdisciplinary STEAM+ Journal

We lead quantified lives. The information we send and receive through our computers, CD players, and smart phones is coded in ones and zeroes. We exist as numerical accounts, license numbers, and login IDs. Anyone who has ever waited on hold for a live customer service representative understands the desire to be treated like a person, not a number. We each want acceptance for our inherent peculiarities and consideration for our circumstance—conditions we believe extrinsic to numbers.

Promoting The Study Of Wrongful Convictions In Criminal Justice Curricula, Jessica S. Henry

Department of Justice Studies Faculty Scholarship and Creative Works

Criminal justice education promotes interdisciplinary learning, critical thinking skills, and ethical decision making. A course on wrongful convictions falls squarely within that paradigm, as it draws upon criminology, criminal justice, law, psychology, and forensic science to examine basic assumptions about the criminal justice system and the actors within it. In a wrongful convictions course, students learn to think critically about the criminal justice system, and what happens when it fails to function as it should. Students identify practice and policy reforms that improve the accuracy and reliability of the system. This article first considers the broad objectives of criminal justice …

Detecting Deception Via Eyeblink Frequency Modulation, Brandon S. Perelman

Michigan Tech Publications, Part 1

To assess the efficacy of using eyeblink frequency modulation to detect deception about a third party, 32 participants were sent on a mission to deliver a package to an interviewer. 17 of the participants lied to the interviewer about the details of their mock mission and 15 responded truthfully. During the interview, eyeblink frequency data were collected via electromyography and recorded video. Liars displayed eye- blink frequency suppression while lying, while truth tellers exhibited an increase in eyeblink frequency during the mission relevant questioning period. The compen- satory flurry of eyeblinks following deception observed in previous studies was ab- sent …

Investigating Habits: Strategies,Technologies And Models, Kyle S. Smith, Ann M. Graybiel

Dartmouth Scholarship

Understanding habits at a biological level requires a combination of behavioral observations and measures of ongoing neural activity. Theoretical frameworks as well as definitions of habitual behaviors emerging from classic behavioral research have been enriched by new approaches taking account of the identification of brain regions and circuits related to habitual behavior. Together, this combination of experimental and theoretical work has provided key insights into how brain circuits underlying action-learning and action-selection are organized, and how a balance between behavioral flexibility and fixity is achieved. New methods to monitor and manipulate neural activity in real time are allowing us to …

Development And Preliminary Evaluation Of A Telephone-Based Mindfulness Training Intervention For Survivors Of Critical Illness, Christopher E. Cox, Laura S. Porter, Pamela J. Buck, Mary Hoffa, Derek Jones, Brenda Walton, Catherine L. Hough, Jeffrey M. Greeson

College of Science & Mathematics Departmental Research

Rationale: Persistent symptoms of psychological distress represent an unmet need among intensive care unit (ICU) survivors.

Objectives: We aimed to develop and pilot test a simple telephone-based mindfulness training intervention to address this population’s unique needs.

Methods: Open trial involving survivors of medical and surgical critical illness and their informal caregivers, using a pretest–posttest design.

Measurements and Main Results: We developed a six-session, telephone-delivered, ICU survivor–specific mindfulness intervention based on past focus groups, the medical literature, and the precedent of the most effective components of existing mindfulness programs. A total of 11 survivors of mechanical ventilation were enrolled, together with …

Personality Affects Learning And Trade-Offs Between Private And Social Information In Guppies, Poecilia Reticulate, Larissa Trompf, Culum Brown

Sentience Collection

The acquisition of information such as the location and quality of food, mates or shelter is a key survival requirement for animals. Individuals can acquire information through personal experience (private information) or through observing and interacting with others (social information). Environmental spatial and temporal heterogeneity can mean that sometimes social information conflicts with private knowledge. We tested how personality affected the importance placed on public versus private information in wild female guppies when these two information sources came into conflict. We found that boldness and sociality affected decisions to use conflicting social and private information. Bolder females used social information …

Direct And Relational Representation During Transitive List Linking In Pinyon Jays (Gymnorhinus Cyanocephalus), Cynthia Wei, Alan Kamil, Alan B. Bond

Alan Bond Publications

The authors used the list-linking procedure (Treichler & Van Tilburg, 1996) to explore the processes by which animals assemble cognitive structures from fragmentary and often contradictory data. Pinyon jays (Gymnorhinus cyanocephalus) were trained to a high level of accuracy on two implicit transitive lists. They were then given linkage training on the single pair that linked the two lists into a composite, 10-item hierarchy. Following linkage training, the birds were tested on nonadjacent probe pairs drawn both from within (B-D and 2–4) and between (D-1, E-2, B-2, C-3) each original list. Linkage training resulted in a significant transitory disruption in …

Inter-Religious Relationships And Anxiety In The Regulation Of Automatic Inter-Religious Prejudice, Karla J. Felix

Dissertations, Theses, and Capstone Projects

Shared reality theory predicts and evidence suggests that inter-religious relationships are motivated to maintain or regulate interpersonal interactions with others. However, this motivation has been given little attention within the automatic attitude literature. This research is centered on the idea that automatic prejudice is moderated by two fundamental themes, shared reality and anxiety. These themes are reviewed to determine the degree to which participants socially tune to ingroup versus outgroup religious experimenters. In Experiment 1, automatic inter-religious attitudes toward Christian and Jewish experimenters were assessed via a subliminal prime procedure. Religious orientation (extrinsic, intrinsic) and regulation of inter-religious relationships were …

"When I Heard About The March": Testimonies And Participatory Archiving In Peacebuilding, Carolina Muñoz Proto

Dissertations, Theses, and Capstone Projects

This dissertation studies the Memoscopio archive and its collection of testimonies about the 2009 World March for Peace and Nonviolence (the March). This collection came into existence during 2009 and 2010 through a participatory archiving project carried out by a team of peace advocates and researchers in collaboration with March participants. The March was a transnational and decentralized campaign that promoted peace, nonviolence, and justice through activities in 600 cities, social media, and a three-month march around the world. Through the case of Memoscopio and the March, this dissertation explores the personal and cultural meanings of transnational peace marchers in …

Development Of A Model Of Participation Of Community-Based, Discretionary Activities By People Who Use Wheelchairs, Anita Perr

Dissertations, Theses, and Capstone Projects

This cross-sectional research analyzed an existing data set of 302 wheelchair users to identify the psychosocial predictors of participation in community-based, discretionary activities. Two defining elements of participation were studied: the extent of participation and satisfaction with participation. Descriptive analyses of the participants' demographic information and portions of four assessments were completed first. Regression analyses were then used to systematically eliminate potential covariates until the significant psychosocial covariates of the extent of and satisfaction with participation were identified. Perceived control over one's life and perceived reintegration to social function were found to predict the extent of participation. Perceived control also …

Affective Language And Attitudes Toward Public Policy, Rachel A. Wolitzky

Dissertations, Theses, and Capstone Projects

This dissertation project focused on affective and unconscious processes involved in the evaluation of public policy. It follows recent scholarship in political psychology showing how the response to political messages depends greatly on what values and emotions are evoked. Of particular focus has been the notable discrepancy between the conscious way people construe their political judgments and the unconscious operations that more truly account for their views and actions. Motivated by a neuroscientific and psychoanalytic model of the mind and brain that recognizes both the pre-eminence of unconscious (implicit) processing and the primacy of affect in mind (brain) activity, this …

Effects Of 5-Hydroxytryptamine 2c Receptor Agonist Mk212 And 2a Receptor Antagonist Mdl100907 On Maternal Behavior In Postpartum Female Rats, Weihai Chen, Qi Zhang, Wenxin Su, Yu Yang, Jing Qiao, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

Maternal behavior in rats is a highly motivated and well-organized social behavior. Given the known roles of serotonin (5-HT) in emotion, motivation, social behavior, and major depression – and its known interaction with dopamine – it is likely that serotonin also plays a crucial role in this behavior. So far, there are surprisingly few studies focusing on 5-HT in maternal behavior, except for maternal aggression. In the present study,we examined the effects of 5-HT_2C receptor agonism and 5-HT_2A receptor antagonism on maternal behavior in postpartum female rats.We hypothesized that activation of 5-HT_2C receptors and blockade of 5-HT …

Pipeline Revision: A Call To Change, Roni Reiter-Palmon, Pablo P. L. Tinio

Psychology Faculty Publications

Comments on the original article by Matthew Makel (see record 2014-06823-002) which raises an important concern regarding selfcorrection in science. While the notion that science should be self-correcting, and is failing, is not new, recent events in both social and biological sciences have led to a renewed call to develop approaches that would allow for self-correction ( Economist, 2013). Makel addresses a number of issues that hinder self-correction through replications and suggests a number of solutions. In this commentary, we as the editors of Psychology of Aesthetics, Creativity, and the Arts (PACA), would like to offer our perspective. …

Coaching: What Business And Social Researchers Need To Know About It, Raymond L. Forbes

All Faculty and Staff Scholarship

This paper explores the historical and current world of organizational coaching. Coaching is offered as a means of assistance to aid organizational leaders in effectively responding to the stressful external and internal demands associated with their positions or ones to which they aspire. Coaching is also discussed as a vehicle for improving individual and team performance as well as for actualizing a leader’s inherent potential. This work draws heavily upon current literature and practice in both the leadership and coaching fields. It also provides a review of relevant theory, contrasts the roles of leader and manager, defines executive coaching, and …

Direct Control Of Visual Perception With Phase-Specific Modulation Of Posterior Parietal Cortex, Andrew Jaegle, Tony Ro

Publications and Research

We examined the causal relationship between the phase of alpha oscillations (9–12 Hz) and conscious visual perception using rhythmic TMS (rTMS) while simultaneously recording EEG activity. rTMS of posterior parietal cortex at an alpha frequency (10 Hz), but not occipital or sham rTMS, both entrained the phase of subsequent alpha oscillatory activity and produced a phase-dependent change on subsequent visual perception, with lower discrimination accuracy for targets presented at one phase of the alpha oscillatory waveform than for targets presented at the opposite phase. By extrinsically manipulating the phase of alpha before stimulus presentation, we provide direct evidence that the …

The Neurodevelopment Of Basic Sensory Processing And Integration In Autism Spectrum Disorder, Alice Brown Brandwein

Dissertations, Theses, and Capstone Projects

This thesis presents three studies that together explore the neurophysiological basis for the sensory processing and integration abnormalities that have been observed in autism spectrum disorder (ASD) since the disorder was first described over half a century ago. In designing these studies we seek to fill a hole that currently exists in the research community‟s knowledge of the neurodevelopment of basic multisensory integration -- both in children with autism and as well as in those with typical development. The first study applied event related potentials (ERPs) and behavioral measures of multisensory integration to a large group of healthy participants ranging …
