Progression And Protectiveness Of Social Bonds And Play In A Captive Group Of Western Lowland Gorillas, Madeline L. Vandevere Jan 2023

Progression And Protectiveness Of Social Bonds And Play In A Captive Group Of Western Lowland Gorillas, Madeline L. Vandevere

West Chester University Doctoral Projects

The current study aims to bring to light the critical role that play has on healthy development, not only for nonhuman primates, but also for humans. In addition to building the literature concerning social and play development among gorillas and humans, this study also hopes to promote the observation and welfare of captive gorillas. The present study conducted longitudinal observational research of a troop of captive western lowland gorillas (Gorilla gorilla gorilla) to gain insights into primate play development and how it relates to social bonding and zoological enrichment. The study followed the early infancy and juvenile years …


From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood Jun 2021

From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood

Dissertations, Theses, and Capstone Projects

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Domestication And Cognitive Complexity, David R. Brodbeck, Madeleine I. R. Brodbeck, Keeghan Rosso Jan 2019

Domestication And Cognitive Complexity, David R. Brodbeck, Madeleine I. R. Brodbeck, Keeghan Rosso

Animal Sentience

Marino and Merskin (2019) list a number of tasks that sheep can perform well. As comparative psychologists, we are not surprised by these results. Indeed, many domesticated animal species show similar abilities.


Exploring Temperament In Beluga Whale Calves (Delphinapterus Leucas), Beri Brown Dec 2018

Exploring Temperament In Beluga Whale Calves (Delphinapterus Leucas), Beri Brown

Dissertations

Studies of personality and temperament in humans span many disciplines, although animal research is still relatively undeveloped. Research investigating stable individual differences in marine mammals has been limited, and to date there have not been any studies with beluga whales. As an ongoing longitudinal study, seven beluga calves, housed at SeaWorld San Antonio, were videotaped throughout their first two years of life. Four videos were selected from archived video recordings for each calf from the following nine phases: newborn phase (month 1), Q1 (month 2-3), Q2 (month 4-6), Q3 (month 7-9), Q4 (month 10-12), Q5 (month 13-15), Q6 (month 16-18), …


The Conundrum Of Causal Reasoning In Elephants, Beri Brown May 2018

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly looked …


Engaging Undergraduates In Comparative Psychology: A Case Study, Lauren Highfill, Deirdre Yeater Jan 2018

Engaging Undergraduates In Comparative Psychology: A Case Study, Lauren Highfill, Deirdre Yeater

Psychology Faculty Publications

With many comparative psychologists teaching at small colleges and universities where resources are limited, maintaining a traditional animal laboratory housing rats or pigeons is not realistic for many of these researchers. One way to overcome this lack of overhead costs and extensive lab space, is to forge collaborations with local zoos and aquariums. Zoo and aquarium research projects provide a way to examine a wide range of species, which is an important tenet within the field of comparative psychology. Furthermore, many undergraduates are innately attracted to the prospect of working with exotic animals. Here, we propose utilizing visitor behavior research …


Replicability And Reproducibility In Comparative Psychology, Jeffrey R. Stevens May 2017

Replicability And Reproducibility In Comparative Psychology, Jeffrey R. Stevens

Jeffrey Stevens Publications

Psychology faces a replication crisis. The Reproducibility Project: Psychology sought to replicate the effects of 100 psychology studies. Though 97% of the original studies produced statistically significant results, only 36% of the replication studies did so (Open Science Collaboration, 2015). This inability to replicate previously published results, however, is not limited to psychology (Ioannidis, 2005). Replication projects in medicine (Prinz et al., 2011) and behavioral economics (Camerer et al., 2016) resulted in replication rates of 25 and 61%, respectively, and analyses in genetics (Munafò, 2009) and neuroscience (Button et al., 2013) question the validity of studies in those fields. Science, …


Peace And The Human Animal: Toward Integration Of Comparative Evolutionary Psychology And Peace Studies., Nancy Dess Jun 2012

Peace And The Human Animal: Toward Integration Of Comparative Evolutionary Psychology And Peace Studies., Nancy Dess

Nancy K Dess

Peace is arguably the problem of the 21st century. Peacefulness is not uniquely human, but a dearth of it among humans disproportionately threatens people and other animals around the globe. The urgent need for peace—if not immediately, everywhere, at any cost, then soon, as a pervasive norm—coincides with unprecedented scholarly attention to peace and to the implications of evolution for psychological functioning in the context of complex sociality. The time is ripe to integrate evolutionary perspectives into peace studies. Toward that end, this chapter describes potential impediments to an evolutionary peace project, provides a basic lexical and conceptual tool kit, …
