Relevance of non-human animal studies to the understanding of human sexuality

There are several reasons for studying sexual behavior in animals other than the human. Prominent among these is probably the use of sexual behavior as a model system for analyzing hormone actions on the brain. In this kind of study, lordosis behavior in the female rat has frequently been used as the behavioral end-point. Recently, the mouse has become a popular subject because of the availability of strains lacking estrogen or progesterone receptors. Animal sexual behavior is also studied for its own sake by biologists, by agricultural scientists and by those interested in the management of wildlife resources. Finally, there are some researchers interested in human sexual behavior who prefer to approach their problems through studies in non-human subjects, as they thereby gain access to techniques of experimentation impossible in human subjects. This is particularly important when the neurobiological basis of sexual behavior is the subject of study. Two striking similarities between humans and other mammals are the hormone dependency of sexual motivation and the fundamentally bisexual organization of the nervous system. In addition, animal studies have revealed how learning with sexual reinforcement can be an important determinant of sexual behavior. The role of learning has been largely ignored in human studies, and this has led to many misconceptions. Paramount among these is the idea that sexual behavior is associated with reproduction.     

Dogs in Animal Shelters: Problems, Suggestions, and Needed Expertise

Because of very real practical constraints, conditions in animal shelters are often reminiscent of those in early primate deprivation studies. Dogs are frequently surrendered to shelters because of behavior problems, and aspects of the shelter environment may induce anomalous behavior, increasing the chances that adopted dogs will be returned to the shelters. Comparative psychologists, psychobiologists, and other behavioral scientists possess the knowledge and techniques to help shelters intervene in this cycle. Experience suggests human interaction and the application of basic conditioning procedures can reduce the impact of the shelter environment, and ease the transition into the adoptive home. A program developed to meet these goals is described. Shelters can provide opportunities both for the training of students in animal-related exercises and for limited applied research. Behavioral scientists stand in a unique position to help transform conditions in animal shelters to the benefit of all involved.     

Living the eighth day online: liturgies,sacramental life,and building human relationships

ABSTRACT

Online human relationships can exacerbate some of the worst of our tendencies toward each other, including deception, selfishness, apathy and disembodiment, and sexual harassment. Yet Christians can also bring their prayer practices online, as ways of bringing God’s new creation (known in Christian tradition as the Eighth Day) to the forefront. Through examination of three distinctive online prayer practices, combined with discussion of liturgical and sacramental theologies, this article shows that prayer online also holds out possibilities of reconciliation and justice as potential responses to negative human relationship tendencies.     

ANIMALS,ANIMISTS, AND ACADEMICS

Abstract. Animism is the label given to worldviews in which the world is understood to be a community of living persons, only some of whom are human. (An older use of the term to label a putative “belief in spirits” is less useful.) Animists inculcate locally meaningful means of communicating with other‐than‐human persons, especially in order to express respect. Ethnographic accounts of particular animist ways of engaging with animal persons are noted. I argue that ethologists interested in engaging respectfully with animals while researching cognition, behavior, and other critical issues may find their research methods and results enhanced by learning from animists about tested methods of communicating with animals. The mediation of animists in this communicative engagement between animals and those who research among them is proposed not as a romantic gloss on modernist culture but in full recognition that the challenge offered by dialogue with marginalized and excluded “others” may result in a reconfiguration of academic protocols. Nonetheless, this entry into full relationality is seriously posed as an improved means of achieving established goals of understanding animals, humans, and the world we coinhabit.     

The human side of animal behavior

An important element of behavioral research with nonhuman animals is that insights are drawn from it about human behavior, what is called here the human side of animal behavior. This article examines the origins of comparing human behavior to that of other animals, the ways in which such comparisons are described, and considerations that arise in evaluating the validity of those comparisons. The rationale for such an approach originated in the reductionism of experimental physiology and the understanding of the commonalities of all life forms promulgated by Darwinian evolutionary biology. Added more recently were such observations as the relative simplicity of animal behavior, tempered by the constraints placed on resulting comparisons by the absence of verbal behavior in animals. The construction of comparisons of human behavior to that of animals may be framed on the basis of Skinner's (1957) distinction between the metaphorical and generic forms of the extended tact. Both ordinary and systematic comparisons of animal and human behavior are congruent with Skinner's extended tact framework. The most general consideration in evaluating comparisons of animal and human behavior is that a functional basis for the claimed similarity be established. Systematic analysis and convergent evidence also may contribute to acceptability of these comparisons. In the final analysis, however, conclusions about the human side of animal behavior are nondeductively derived and often are assessed based on their heuristic and pragmatic value. Such conclusions represent a valuable contribution to understanding the human animal and in developing practical solutions to problems of human behavior to which much of psychology is dedicated.     

Dominance, leadership, and aggression: animal behavior studies during the Second World War

During the decade surrounding the Second World War, an extensive literature on the biological and psychological basis of aggression surfaced in America, a literature that in general emphasized the significance of learning and environment in the origins of aggressive behavior. Focusing on the animal behavior research of Warder Clyde Allee and John Paul Scott, this paper examines the complex interplay among conceptual, institutional, and societal forces that created and shaped a discourse on the subjects of aggression, dominance, and leadership within the context of World War II. The distinctions made between sexual and social dominance during this period, distinctions accentuated by the threat of totalitarianism abroad, and the varying ways that interpretations of behavior could be negotiated attests to the multiplicity of interactions that influence the development of scientific research.     

Sexual promiscuity & self-control: A behavior genetic explanation to an evolutionary question

Within separate academic disciplines there exist two consistent findings that have emerged. Behavior geneticists, on one hand, continue to uncover moderate to high heritability estimates for virtually every human trait measurable. Evolutionary psychologists, on the other hand, have thoroughly documented species-wide universality in various human traits, suggesting that natural (or sexual) selection may have directly favored such outcomes. The goal of the current study, then, is to explore ways in which these lines of inquiry can be united via the use of behavior genetic methodologies coupled with evolutionary thought. Additionally, we attempt to unite our findings in a framework that can both account for the existence of heritable individual differences, while also understanding the importance of species-wide characteristics.     

进化心理学视角下的两性冲突与缓和

进化心理学观点认为两性冲突是一个性别达到最佳适应的过程被另一个性别所阻碍,其根本原因是两性繁衍成功的根本进化利益存在冲突。从进化心理学的角度,根据两性敌对性选择理论,两性冲突可以分为基因座内的两性冲突与基因座间的两性冲突,前者可由性选择理论解释,后者涉及到两性的适应与反适应以及在军备竞赛中的协同进化。而两性冲突缓和则可以由费舍尔模型与基因复制理论、性别二态性和一夫一妻制度解释。两性冲突及缓和也分别具有进化心理学的相关实证依据支持。未来两性冲突领域的研究需要提升研究方法的客观性及两性冲突特质的多样性,并关注两性冲突缓和的现实有效途径以及婚配制度与评估方式对繁衍成功的交互作用。     

Gender and sexual orientation differences in sexual response to sexual activities versus gender of actors in sexual films

In this study, the authors investigated the hypothesis that women's sexual orientation and sexual responses in the laboratory correlate less highly than do men's because women respond primarily to the sexual activities performed by actors, whereas men respond primarily to the gender of the actors. The participants were 20 homosexual women, 27 heterosexual women, 17 homosexual men, and 27 heterosexual men. The videotaped stimuli included men and women engaging in same-sex intercourse, solitary masturbation, or nude exercise (no sexual activity); human male-female copulation; and animal (bonobo chimpanzee or Pan paniscus) copulation. Genital and subjective sexual arousal were continuously recorded. The genital responses of both sexes were weakest to nude exercise and strongest to intercourse. As predicted, however, actor gender was more important for men than for women, and the level of sexual activity was more important for women than for men. Consistent with this result, women responded genitally to bonobo copulation, whereas men did not. An unexpected result was that homosexual women responded more to nude female targets exercising and masturbating than to nude male targets, whereas heterosexual women responded about the same to both sexes at each activity level.     

Learning about food: starlings, skinner boxes, and earthworms

Despite its importance as a tool for understanding a wide range of animal behavior, the study of reinforcement schedules in the laboratory has suffered from difficulties in the biological interpretation of its findings. This study is an operant-laboratory investigation of the ability of European starlings, Sturnus vulgaris, to learn to respond adaptively to the problem of foraging on patchily distributed prey that are uncertainly located in space. In order to maximize the biological relevance of the laboratory study, variation in the aggregation of earthworms, Lumbricus terrestris (a prey species), was rigorously quantified from the field, and the experimental birds were presented with reinforcement schedules designed to represent the extremes of the observed variation. The results demonstrate that, even for a single prey species, the degree to which individuals are aggregated can vary markedly over a range of spatial scales, and that starlings can rapidly learn to respond, in an adaptive manner, to these variations. These findings suggest that starlings are capable of adjusting their behavior to facilitate the efficient exploitation of prey that occurs in patches of an uncertain nature, and thus illustrate the heuristic value of an ecologically informed operant-laboratory approach to studying foraging behavior.     

Basic research needed for stimulating the development of behavioral technologies

The costs of disconnection between the basic and applied sectors of behavior analysis are reviewed, and some solutions to these problems are proposed. Central to these solutions are collaborations between basic and applied behavioral scientists in programmatic research that addresses the behavioral basis and solution of human behavior problems. This kind of collaboration parallels the deliberate interactions between basic and applied researchers that have proven to be so profitable in other scientific fields, such as medicine. Basic research questions of particular relevance to the development of behavioral technologies are posed in the following areas: response allocation, resistance to change, countercontrol, formation and differentiation/discrimination of stimulus and response classes, analysis of low-rate behavior, and rule-governed behavior. Three interrelated strategies to build connections between the basic and applied analysis of behavior are identified: (a) the development of nonhuman animal models of human behavior problems using operations that parallel plausible human circumstances, (b) replication of the modeled relations with human subjects in the operant laboratory, and (c) tests of the generality of the model with actual human problems in natural settings.     

Dietary interventions,the gut microbiome,and aggressive behavior: Review of research evidence and potential next steps

Research in biosocial criminology and other related disciplines has established links between nutrition and aggressive behavior. In addition to observational studies, randomized trials of nutritional supplements like vitamins, omega-3 fatty acids, and folic acid provide evidence of the dietary impact on aggression. However, the exact mechanism of the diet-aggression link is not well understood. The current article proposes that the gut microbiome plays an important role in the process, with the microbiota–gut–brain axis serving as such a mediating mechanism between diet and behavior. Based on animal and human studies, this review synthesizes a wide array of research across several academic fields: from the effects of dietary interventions on aggression, to the results of microbiota transplantation on socioemotional and behavioral outcomes, to the connections between early adversity, stress, microbiome, and aggression. Possibilities for integrating the microbiotic perspective with the more traditional, sociologically oriented theories in criminology are discussed, using social disorganization and self-control theories as examples. To extend the existing lines of research further, the article considers harnessing the experimental potential of noninvasive and low-cost dietary interventions to help establish the causal impact of the gut microbiome on aggressive behavior, while adhering to the high ethical standards and modern research requirements. Implications of this research for criminal justice policy and practice are essential: not only can it help determine whether the improved gut microbiome functioning moderates aggressive and violent behavior but also provide ways to prevent and reduce such behavior, alone or in combination with other crime prevention programs.     

A ganglionic model of “learned helplessness”

The phenomenon known as “learned helplessness” (LH) is seen broadly across the animal kingdom. Some of the basic characteristics of this behavior are: failure to escape shock when it is possible to do so following non-escapable shock; reversion to non-escape behavior even after successful escape; if the animal is given escape/avoidance training prior to being given inescapable shocks, the latter will not interfere with its ability to later show normal escape/avoidance behavior (generally described as an immunization effect); following inescapable shock training the animals often become “passive and still” when confronted with an escapable shock. These behaviors are seen in intact mammals, lower vertebrates, and invertebrates. In fact, the basic characteristics are even seen in a spinal rat and, with the exception of one characteristic not yet examined, in an isolated thoracic ganglion of an insect. The brain is evidently not essential either in mammals or in invertebrates for demonstrating this behavior. Not only can an insect ganglion show the behavioral characteristics of LH, but the neural information underlying the phenomenon of LH can be shown to transfer from one ganglion innervating one pair of legs to another ganglion innervating a different pair of legs. Thus, how CNS information underlying LH is coded and transferred from one site to another within the CNS can be examined in such a system. The LH model has provided valuable insights into the physiology of depression. This model suggests that human depression is caused by one’s lack of control over traumatic events. It is supported by a number of parallels between depression and LH behavior. Tricyclic antidepressants, MAO inhibitors, and ECT, which are effective in treating depression, also can prevent and reverse LH in mammals. It would be important to find out if they are also effective in invertebrate models. The fact that the characteristics of the behavior called LH are seen in invertebrates such as slugs, cockroaches, and locusts provokes other intriguing questions about the presence of cognition at these phylogenetic levels, as well as what animal or preparation constitutes an appropriate model for human depression.     

The valence of sex:Automatic affective associations in erotophilia and erotophobia

Sexual stimuli may elicit positive and negative emotions that can impact sexual thoughts, responses, and behavior. To date, most research on affect and sexuality has focused on conscious processes and affective states. Less is known about how automatic and trait-level affective processes influence our reactions to sexual stimuli. This study used a priming task with backward masking and a trait measure of erotophobia-erotophilia - the tendency to respond to sex on a negative-to-positive continuum - to improve our understanding of the role of automatic and affective processes in response to sexual stimuli. Erotophilic individuals demonstrated automatic associations between sexual primes and positively-valenced targets, whereas erotophobic individuals classified negatively-valenced targets faster regardless of whether primes were sexual or neutral. The findings suggest that the valence of sexual stimuli can be processed automatically and is associated with trait-level affective responses to sex. Implications for research on risky sexual behavior and sexual dysfunction are discussed.     

Three-dimensional spatiotemporal imaging of movement patterns: Another step toward analyzing the continuity of behavior

Computer-aided spatiotemporal imaging techniques, like those that are proving to be important in many other scientific fields, are being used to represent and study movement patterns of animals exposed to basic reinforcement contingencies. Data from a video-tracking system that provides real-time tracking of the position of an experimental animal as it moves about in a three-dimensional space can be plotted in up to three dimensions. When the data are plotted in two spatial dimensions and the time dimension, behavior is captured as continuous patterns or structures in space-time. Spatiotemporal imaging of movement patterns permits regularities to be observed that are not seen as readily in other ways such as watching videotapes of the experimental sessions or simply examining rate of responding. By providing a concise spatiotemporal representation of the movement patterns that occurred in a given experimental preparation, the imaging techniques described here represent an advancement in the scientific study of continuously flowing behavior. Although we concentrate here on movement patterns produced by basic reinforcement contingencies, the spatiotemporal imaging technology is applicable to any research topic in which movement patterns are of interest, such as foraging, place learning, sign language, and limb movement.     

Aristotle's Cognitive Science: Belief,Affect and Rationality

I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non‐rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the pathways between cognition and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non‐rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non‐vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings.     

Sexual desire,not hypersexuality,predicts self-regulation of sexual arousal

A person's ability to control their own sexual arousal is important both to reduce the risks associated with some sexual behaviours and to respond sexually with intimate partners. A lack of control over sexual urges is a proposed feature of “hypersexual disorder”, though some evidence suggests that sexual desire predicts the self-regulation of sexual arousal better than hypersexuality. In the current study, a sample (N = 116) of men and women recruited from community ads viewed a series of 20-second neutral and sexual films. Before each sexual film, participants were instructed to increase their sexual arousal, decrease their sexual arousal or respond as usual. Higher levels of desire for sex with a partner consistently predicted failures to downregulate sexual arousal. Hypersexuality was unrelated. These findings replicate Winters et al.'s study and extend their findings by including upregulation, women, a new measure of hypersexuality and a higher-trial design.     

“Brands as Intentional Agents”: Questions and extensions

The notion that consumers' relationships with brands can be characterized in ways that resemble their relationships with people is gaining considerable ground in the areas of consumer behavior and branding. Kervyn, Fiske and Malone's “Brands as Intentional Agents” offers additional support for this basic proposition. The authors argue that the ability to translate research on human social interaction relationships with brand relationships provides useful insights into brand positioning and brand communications. This author, while raising a few general questions about the SCM and BIAF models, identifies additional research questions in the consumer behavior and branding domains that might be informed by the basic components of the SCM model.     

Extracting Low-Dimensional Psychological Representations from Convolutional Neural Networks

Convolutional neural networks (CNNs) are increasingly widely used in psychology and neuroscience to predict how human minds and brains respond to visual images. Typically, CNNs represent these images using thousands of features that are learned through extensive training on image datasets. This raises a question: How many of these features are really needed to model human behavior? Here, we attempt to estimate the number of dimensions in CNN representations that are required to capture human psychological representations in two ways: (1) directly, using human similarity judgments and (2) indirectly, in the context of categorization. In both cases, we find that low-dimensional projections of CNN representations are sufficient to predict human behavior. We show that these low-dimensional representations can be easily interpreted, providing further insight into how people represent visual information. A series of control studies indicate that these findings are not due to the size of the dataset we used and may be due to a high level of redundancy in the features appearing in CNN representations.     

ANIMAL PASSIONS AND BEASTLY VIRTUES: COGNITIVE ETHOLOGY AS THE UNIFYING SCIENCE FOR UNDERSTANDING THE SUBJECTIVE,EMOTIONAL, EMPATHIC,AND MORAL LIVES OF ANIMALS

Abstract. In this essay, my response to four papers that were presented at the 2004 annual meeting of the American Academy of Religion in a session devoted to my research on animal behavior and cognitive ethology, I stress the importance of interdisciplinary research and collaboration for coming to terms with various aspects of animal behavior and animal cognition. I argue that we have much to learn from other animals concerning a set of “big” questions including who we are in the grand scheme of things, the role science (“science sense”) plays in our understanding of the world in which we live, what it means to “know” something, what some other ways of knowing are and how they compare to what we call “science,” and the use of anecdotes and anthropomorphism to inform studies of animal behavior. I ask, Are other minds really all that private and inaccessible? Can a nonhuman animal be called a person? What does the future hold if we continue to dismantle the only planet we live on and persecute the other animal beings with whom we are supposed to coexist? I argue that cognitive ethology is the unifying science for understanding the subjective, emotional, empathic, and moral lives of animals, because it is essential to know what animals do, think, and feel as they go about their daily routines in the company of their friends and when they are alone. It is also important to learn why both the similarities and differences between humans and other animals have evolved. The more we come to understand other animals, the more we will appreciate them as the amazing beings they are, and the more we will come to understand ourselves.
