SIGNED: Sarah Beth Burger 4 ACKNOWLEDGEMENTS Few things are harder to put up with than the annoyance of a good example. -Mark Twain I would like to thank Dr. W. Jake Jacobs for his substantial theoretical contributions to this project. I would also like to thank my committee, Dr. W. Jake Jacobs, Dr. Alfred Kaszniak, Dr. David Sbarra, and Dr. Richard Bootzin for their invaluable constructive criticism and feedback, which further strengthened this work. I would also like to thank the outstanding group of undergraduate research assistants who have worked with me on this project, without whom completion would have been impossible. In particular, I would like to thank Matthew Kleinman, Sean Whitson, and David Sawyer for their theoretical contributions to the design of this project following pilot procedures. I would also like to thank Sean Whitson and his father for building the track used within this investigation, and Todd Burgess for his frequent assistance with maintenance and upkeep of the track during the investigative period. Finally, I would like to thank my committee and Dr. W. Jake Jacobs in particular for the outstanding mentorship and support I’ve received throughout my graduate career. It has been refreshing to be both stretched and nurtured by the brilliant minds that compose my dissertation committee; I will forever be grateful for the opportunity I had to study here, and for the friendships, collegial and collaborative relations I made along the way. 5 DEDICATION The culmination of this work celebrates a wonderful phase of my life, and ushers in another. I could never have finished this without the love and support of so many I am blessed to call family. I can’t possibly mention everyone who has helped me get here in this short paragraph, but there are a few whose contributions to both my development and my happiness demand mention. I dedicate this to “Grandpa Jake,” who created an environment supportive of both research and motherhood. I dedicate this to my husband Shaun, who loves me for me and keeps me grounded. I dedicate this to my daughter Bethany, whose enthusiasm for learning and naturalistic observation skills have given me enough research ideas to fill three careers. I dedicate this to my sister Tracey, who inspires me to be better and understands me like no other. I dedicate this to my twin Amy, the one I entrusted to nurture Bethany’s brain in my absence while I wrote this thing up! I dedicate this to my father, who I am more like than I used to realize. Finally, and most importantly, I dedicate this to my mother, who instilled in me a wonderful sense of independence and fostered a drive that has taken me further than either of us imagined I would go; I love you mom. 6 TABLE OF CONTENTS LIST OF TABLES..............................................................................................................9 LIST OF FIGURES...........................................................................................................10 ABSTRACT.......................................................................................................................11 INTRODUCTION AND LITERATURE REVIEW.........................................................13 Overview........................................................................................................................13 Expectancies…………………………………………………………………………..15 Arachnophobia ……………………………………………………………………….15 Prevalence……………………………………………………………………….16 Behavioral vs. Cognitive-Behavioral Models of Fear Learning and Avoidance..16 Neo-Behavioral Models of Specific Fear………………………………..17 Cognitive Models of Overprediction of Fear……………………………18 The Match-Mismatch Hypothesis.……………………...………..19 Summarized Predictions for the Two Primary Questions of Interest…………………22 Spider Fear in Focused Review……………………………………………………….23 The Nature of Fear: Latent or Emergent Construct?…...…………………………24 Revised Conceptualizations of Fear……………………………………..24 A Potential Role for Implicit Measures of Fear ………………………...25 Spider-Fearful vs. Spider-Phobic: A Meaningful Distinction?………………….25 A Matter of Context……………………………………………………………...26 Perceived Danger vs. Perceived Probability of Unwanted Physical Contact ….28 Predictability and Control…………………..………………………………………….29 Empirically Supported Treatment……………………………………………….30 Systematic Desensitization…………………………...………………….30 In Vivo vs. In Vitro Exposure, and Everything In Between…….………31 Toward a Unified Fear Hierarchy………………………………………..33 Specific Aims………………………………………………………………………….33 Specified Hypotheses …………………………………………....................................34 METHOD...…………….……………………………………………………………..…36 Participants...………………………………………………………………………….36 Recruitment Method...…………………………………………………………………36 Measured Sample Characteristics ……………………………………………………37 Materials...…………………………………………………………………………….37 Spider and Spider-Stimuli….………………………………………………….....37 Spider Track and Platform………………………………………………………38 AZ-Live Immersive Environment ………………………………………………..39 Physiological Recording Equipment .……………………………………………39 Predictive Measures .…………………………………………………………………39 Self-Report Measures of Fear .…..……..…….…………………………………39 Diagnostic Clinical Interview ..…………………………………………39 Spider Questionnaire (SPQ) .……………………………………….……40 Fear of Spiders Questionnaire (FSQ)……………………………….……40 7 Self-Report Affective Measures……………………………………….………….41 Spielberger State and Trait Anxiety Inventories (STAI)..………....….…41 Beck Depression Inventory (BDI-II)…………………………..……...…41 Implicit Measure of Spider Fear Intensity……….……………………..…..……42 Teachman’s Implicit Association Test (IAT)…………………..…..……42 Measures of Trial-Specific Fear Predictions……….………………………..…..……43 Self-Report Predictions of Distance, Heart Rate, GSR, and Fear…..…….....…..43 Measures of Trial-Specific Fear Reactions……………………………………....……43 Self-Report Measures of Distance, Heart Rate, GSR, and Fear….……………..43 Direct Observation of Distance………………………….………………....……44 Procedure ……………………………………………………………………………44 Statistical Analysis: ANOVAs with Follow-Up GLMS …………………………....…49 Our GLM Predictor Model Variables: Hierarchical Variance Partitioning…....49 RESULTS.……………………………………………..………………………………..51 Sample Characteristics by Group….…………..……………….……………..…..…51 Relations among Measured Constructs………………………………………......….51 Learning Trials (1-7) Results……………………………………………………..…52 Expectation Accuracy.……..…………………………..……....……...……..….52 Match-Mismatch Data………………………………………………..…52 Statistical Analyses of Expectation Accuracy across Domains…..…..…53 Utility of Expectation Accuracy……………………………………...…54 Directly Observed

  • Evidence for Nanocoulomb Charges on Spider Ballooning Silk
    PHYSICAL REVIEW E 102, 012403 (2020) Evidence for nanocoulomb charges on spider ballooning silk E. L. Morley1,* and P. W. Gorham 2,† 1School of Biological Sciences, University of Bristol, 24 Tyndall Avenue, Bristol BS8 1TQ, United Kingdom 2Department of Physics & Astronomy, University of Hawaii at Manoa, 2505 Correa Rd., Honolulu, Hawaii 96822, USA (Received 10 December 2019; revised 5 March 2020; accepted 6 March 2020; published 9 July 2020) We report on three launches of ballooning Erigone spiders observed in a 0.9m3 laboratory chamber, controlled under conditions where no significant air motion was possible. These launches were elicited by vertical, downward-oriented electric fields within the chamber, and the motions indicate clearly that negative electric charge on the ballooning silk, subject to the Coulomb force, produced the lift observed in each launch. We estimate the total charge required under plausible assumptions, and find that at least 1.15 nC is necessary in each case. The charge is likely to be nonuniformly distributed, favoring initial longitudinal mobility of electrons along the fresh silk during extrusion. These results demonstrate that spiders are able to utilize charge on their silk to attain electrostatic flight even in the absence of any aerodynamic lift. DOI: 10.1103/PhysRevE.102.012403 I.

  • Portia Perceptions: the Umwelt of an Araneophagic Jumping Spider
    Portia Perceptions: The Umwelt of an Araneophagic Jumping 1 Spider Duane P. Harland and Robert R. Jackson The Personality of Portia Spiders are traditionally portrayed as simple, instinct-driven animals (Savory, 1928; Drees, 1952; Bristowe, 1958). Small brain size is perhaps the most compelling reason for expecting so little flexibility from our eight-legged neighbors. Fitting comfortably on the head of a pin, a spider brain seems to vanish into insignificance. Common sense tells us that compared with large-brained mammals, spiders have so little to work with that they must be restricted to a circumscribed set of rigid behaviors, flexibility being a luxury afforded only to those with much larger central nervous systems. In this chapter we review recent findings on an unusual group of spiders that seem to be arachnid enigmas. In a number of ways the behavior of the araneophagic jumping spiders is more comparable to that of birds and mammals than conventional wisdom would lead us to expect of an arthropod. The term araneophagic refers to these spiders’ preference for other spiders as prey, and jumping spider is the common English name for members of the family Saltici- dae. Although both their common and the scientific Latin names acknowledge their jumping behavior, it is really their unique, complex eyes that set this family of spiders apart from all others. Among spiders (many of which have very poor vision), salticids have eyes that are by far the most specialized for resolving fine spatial detail. We focus here on the most extensively studied genus, Portia. Before we discuss the interrelationship between the salticids’ uniquely acute vision, their predatory strategies, and their apparent cognitive abilities, we need to offer some sense of what kind of animal a jumping spider is; to do this, we attempt to offer some insight into what we might call Portia’s personality.

  • The Sublethal Effects of Neonicotinoids on Spiders Are Independent of Their
    www.nature.com/scientificreports OPEN The sublethal efects of neonicotinoids on spiders are independent of their nutritional status Milan Řezáč1, Nela Gloríková1, Shawn M. Wilder2 & Petr Heneberg3* Spiders were recently shown to be adversely afected by feld-realistic concentrations of a broad scale of neonicotinoid insecticides. Among the reported efects of neonicotinoids on invertebrates were declines in lipid biosynthesis and upregulation of β-oxidation, while vertebrate models suggest increased adipogenesis following treatment with neonicotinoids. Therefore, we hypothesized that there exists synergy between the efects of diet and concurrent exposure to feld-realistic concentrations of neonicotinoid insecticides. To address this hypothesis, we fed frst instars of the large wolf spider Hogna antelucana with two types of diets and exposed them to feld-realistic concentrations of three formulations of neonicotinoids (thiamethoxam, thiacloprid and acetamiprid). We then measured the growth of the tested spiders; the lipid and protein content of their bodies; and their behavior, including ballooning, rappelling, and locomotor parameters. The two tested diets consisted of casein-treated and sucrose-treated Drosophila melanogaster. The dietary treatments afected the lipid and protein content of the spiders, their body weight and carapace length but did not afect any of the measured behavioral parameters. Surprisingly, we did not fnd any efects of acute exposure to neonicotinoid insecticides on the lipid or protein reserves of spiders. Exposure to neonicotinoids altered the behavior of the spiders as reported previously in other spider species; however, these efects were not afected by dietary treatments. Overall, the dietary treatments did not have any major synergy with acute exposure to feld-realistic concentrations of neonicotinoid insecticides.

  • Predatory Behavior of the Zebra Spider, Salticus Scenicus (Araneae: Salticidae)
    Predatory behavior of the zebra spider, Salticus scenicus (Araneae: Salticidae) LAWRENCEM. DILL' Department of Biology, York University, Toronto, Ontario Received March 27, 1975 DILL, L. M. 1975. Predatory behavior of the zebra spider, Salticus scenicus (Araneae: Sal- ticidae). Can. J. Zool. 53: 1284-1289. The zebra spider (Salticus scenicus), a small jumping spider, orients towards prey detected by its lateral eyes whenever the angle subtended by such prey exceeds 5.5". The velocity of the prey is not involved in the determination of reactive distance, but only moving objects elicit orienta- tion. The probability that orientation is followed by stalking is a function of both prey size and velocity, but the effects of these parameters on reactive distance for stalking were not deter- mined. The zebra spider's stalk velocity declines progressively as it nears its (stationary) prey, and the probable optimality of this behavioral tactic is discussed. DILL,L. M. 1975.
