A comparative approach to affect and cooperation

A central premise of the science of comparative affect is that we can best learn about the causes and consequences of affect by comparing affective phenomena across a variety of species, including humans. We take as a given that affect is widely shared across animals, but a key challenge is to accurately represent each species' affective experience. A common approach in the comparative study of behavior and cognition is to develop standardized experimental paradigms that can be used across species, with the assumption that if the same task is being used, we can directly compare behavioral responses. This experimental approach rests on two underlying assumptions: first, that different species' perception of and affective response to these paradigms are the same; and second, that behavioral and physiological (including endocrine and neural) responses to these paradigms are homologous; if either of these assumptions is not true, then the comparison becomes much less straightforward. Our goal in the present paper is to summarize the dominant paradigms that have been used for such comparative research, with a particular focus on paradigms common in the cooperation literature, and to critically discuss dominant assumptions about what affective states these tasks can or should measure. We then consider the advantages and drawbacks of this experimental method, and consider alternatives that may improve our understanding. We hope that this will help scholars recognize and avoid pitfalls inherent in studying affect, and stimulate them to create novel, ecologically relevant paradigms for examining affect across the animal kingdom.Action Contro

New Caledonian crows rapidly solve a collaborative problem without cooperative cognition

There is growing comparative evidence that the cognitive bases of cooperation are not unique to humans. However, the selective pressures that lead to the evolution of these mechanisms remain unclear. Here we show that while tool-making New Caledonian crows can produce collaborative behavior, they do not understand the causality of cooperation nor show sensitivity to inequity. Instead, the collaborative behavior produced appears to have been underpinned by the transfer of prior experience. These results suggest that a number of possible selective pressures, including tool manufacture and mobbing behaviours, have not led to the evolution of cooperative cognition in this species. They show that causal cognition can evolve in a domain specific manner-understanding the properties and flexible uses of physical tools does not necessarily enable animals to grasp that a conspecific can be used as a social tool

The effects of individual cubicle research on the social interactions and individual behavior of brown capuchin monkeys (Sapajus apella)

Primates are increasingly being tested individually in purpose-built research centers within zoos. The voluntary nature of research testing indicates that participation is enriching for the primate subjects, but previous studies have generally focused only on stress-related behavior, indicating that the research does not have a negative effect. Few data are available on the effects that individual research may have on social behavior, yet given primates' complex social lives and their responses to how conspecifics are treated, it is important to determine whether individual testing impacts upon their social interactions. The current study compared the social and individual behavior of 11 brown capuchin monkeys (Sapajus apella) between three conditions: (1) directly after undergoing individual testing, (2) a control, and (3) upon returning to the group having voluntarily left. The results indicate that individual and stress-related behaviors were affected very little by individual research testing and that social behaviors increased. However, although affiliative interactions were enhanced, aggressive interactions were also seen to increase in the condition following individual testing compared with the return to group condition. Suggestions for minimizing the negative interactions are given. Provided that these suggestions are taken into account by researchers, our results provide support for developing research centers within zoos given the important findings emerging on our closest living relatives, combined with the potentially positive effects the research has on their welfare

Travel Behavior Over Time

Using detailed travel surveys (the Travel Behavior Inventory) conducted by the Metropolitan Council of the Minneapolis/Saint Paul (Twin Cities) Region in Minnesota for 1990, 2000-2001, and 2010-2011, this report conducts an analysis of changes in travel behavior over time. Specifically looking at changes in travel duration, time, use, and accessibility; telecommuting and its relationship with travel and residential choices; transit service quality and transit use; effects of age and cohort; and changes in walking and bicycling. Much has changed in this period, including the size of the region, demographics, economics, technology, driver licensing, and preferences, examining in turn the effects of investment, development, and population change on behaviors for the Minneapolis-St. Paul region as a whole and for areas within the region. While this research cannot hope to untangle all of the contributing factors, it aims to increase understanding of what did happen, with some explanation of why. This will inform transportation engineers, planners, economists, analysts, and decision makers about the prospective effects of future changes to networks, land use, and demographics while also evaluating the effects of previous network investments

To Each According to His Need? Variability in the Responses to Inequity in Nonhuman Primates

While it is well established that humans respond to inequity, it remains unclear the extent to which this behavior occurs in our nonhuman primate relatives. By comparing a variety of species, spanning from New World and Old World monkeys to great apes, scientists can begin to answer questions about how the response to inequity evolved, what the function of this response is, and why and how different contexts shape it. In particular, research across nonhuman primate species suggests that the response is quite variable across species, contexts and individuals. In this paper, we aim to review these differences in an attempt to identify and better understand the patterns that emerge from the existing data with the goal of developing directions for future research. To begin, we address the importance of considering socio-ecological factors in nonhuman primates in order to better understand and predict expected patterns of cooperation and aversion to inequity in different species, following which we provide a detailed analysis of the patterns uncovered by these comparisons. Ultimately, we use this synthesis to propose new ideas for research to better understand this response and, hence, the evolution of our own responses to inequity

Bats Use Magnetite to Detect the Earth's Magnetic Field

While the role of magnetic cues for compass orientation has been confirmed in numerous animals, the mechanism of detection is still debated. Two hypotheses have been proposed, one based on a light dependent mechanism, apparently used by birds and another based on a “compass organelle” containing the iron oxide particles magnetite (Fe3O4). Bats have recently been shown to use magnetic cues for compass orientation but the method by which they detect the Earth's magnetic field remains unknown. Here we use the classic “Kalmijn-Blakemore” pulse re-magnetization experiment, whereby the polarity of cellular magnetite is reversed. The results demonstrate that the big brown bat Eptesicus fuscus uses single domain magnetite to detect the Earths magnetic field and the response indicates a polarity based receptor. Polarity detection is a prerequisite for the use of magnetite as a compass and suggests that big brown bats use magnetite to detect the magnetic field as a compass. Our results indicate the possibility that sensory cells in bats contain freely rotating magnetite particles, which appears not to be the case in birds. It is crucial that the ultrastructure of the magnetite containing magnetoreceptors is described for our understanding of magnetoreception in animals

The importance of communication and involvementin decision-making: A study in Ireland exploring birthsatisfaction using the Birth Satisfaction Scale-Revised (BSS-R)

Introduction:Evaluation in healthcare services has become a priority, globally1. The Government of Ireland has highlighted the importance of stakeholder engagement to identify the needs of women in the design and delivery of high-quality health services, driven by necessity rather than financial ability2. The Birth Satisfaction Scale-Revised (BSS-R), an internationally validated tool, and recommended for measuring childbirth satisfaction by the International Consortium for Health Outcomes Measurement (ICHOM)3; however, it has yet to be considered in the Irish context. The aim of the study was to explore birth satisfaction with a sample of new mothers in Ireland.Methods:A mixed-methods study was conducted including a survey that involved collection of data from the BSS-R 10-item questionnaire from 307 mothers over an 8-week period in 2019, in one urban maternity hospital in Ireland. Quantitative and qualitative data were collected. Qualitative data from the free-text comments of the survey questions were analyzed using content analysis.Results:Overall, women reported positive relationships with their care providers and were satisfied with the communication and support they received, as well as high levels of control and choice. Postnatal care, however, was highlighted as being less satisfactory with staffing levels described as inadequate.Conclusions:Understanding women’s birth experiences and what is important to them could facilitate midwives and other health professionals to improve the quality of their care and develop guidelines and policies that focus on women and their families’ needs. The vast majority of women rated their birthing experience as extremely positive. The main elements of care that contributed to a positive birthing experience for women were quality relationships with clinicians, choice and control, and emotional safety

Public understandings of addiction: where do neurobiological explanations fit?

Developments in the field of neuroscience, according to its proponents, offer the prospect of an enhanced understanding and treatment of addicted persons. Consequently, its advocates consider that improving public understanding of addiction neuroscience is a desirable aim. Those critical of neuroscientific approaches, however, charge that it is a totalising, reductive perspective–one that ignores other known causes in favour of neurobiological explanations. Sociologist Nikolas Rose has argued that neuroscience, and its associated technologies, are coming to dominate cultural models to the extent that 'we' increasingly understand ourselves as 'neurochemical selves'. Drawing on 55 qualitative interviews conducted with members of the Australian public residing in the Greater Brisbane area, we challenge both the 'expectational discourses' of neuroscientists and the criticisms of its detractors. Members of the public accepted multiple perspectives on the causes of addiction, including some elements of neurobiological explanations. Their discussions of addiction drew upon a broad range of philosophical, sociological, anthropological, psychological and neurobiological vocabularies, suggesting that they synthesised newer technical understandings, such as that offered by neuroscience, with older ones. Holding conceptual models that acknowledge the complexity of addiction aetiology into which new information is incorporated suggests that the impact of neuroscientific discourse in directing the public's beliefs about addiction is likely to be more limited than proponents or opponents of neuroscience expect

“Leaps of faith”: parents' and professionals' viewpoints on preparing adolescents on the autism spectrum for leaving school

Adolescents on the autism spectrum experience difficulty transitioning from secondary school to post-school activities, often due to transition planning processes that do not meet their unique needs. This study identified parents' and professionals' viewpoints on transition planning for adolescents on the autism spectrum. Interviews were completed with nine parents of adolescents on the autism spectrum and four professionals who worked with adolescents on the autism spectrum. A constant comparison approach was used to analyse the transcripts. Four themes were identified, reflecting parents' and professionals' viewpoints on how to meet the transition planning needs of adolescents on the autism spectrum. Supporting adolescents to grasp the big picture can enhance motivation to participate in transition planning. Autism can be an ‘invisible disability’; therefore, encouraging adolescents to be active participants and to be seen in transition planning ensures their individual needs are met. Encouraging adolescents to have high aspirations in transition planning develops their self-determination. Finally, to be prepared for the transition from school may reduce the adolescent's' anxiety. Adolescents on the autism spectrum face unique challenges in transition planning. The themes identified in this study provide insight into how parents and professionals might support adolescents with these challenges
