An Explication of Modern Reasearch on Animal Emotions

The Inception of Emotions in Animals

There is everlasting dissension encompassing the capacitance of nonhuman animals (hereafter animals) to experience emotions (Ekman, 1992). Contemporaneous intelligence insinuates the conceivability of animal sentiments homogenous to those of humans. These span from positive emotions like happiness, love, and elation to negative emotions like fear, embarrassment, and sorrow (Safina, 2015). Scientists are frequently apprehensive of discussing emotionality in animals due to the ineradicable challenges of generating meaningful empirical data to substantiate their hypotheses.

Charles Darwin's approach to this conundrum persists in popularity among modern scientists. As the foremost scientist to formally address this subject, he contended the existence of a harmonious interconnection between human and animal emotions. Darwin maintained that the experience of emotions in animals transmutes in scope and scale, not class and composition. His vindication is the ubiquity of a single shared ancestor through which emotions had evolved for adaptive aid in communication and motivation (Darwin, 1989).

Due to the unique circumstances surrounding animal study, the need for supplementary field experimentation in espousal or demurral of animal emotions endures. Naturalizing experiments is paramount for the generation of steadfast data (Bekoff, 2006). The laboratory's proclivity for psychological transmogrification distorts accumulated data. Cynics indicate the anecdotal and observational essence of current research as sanctioning invalidity ascribed by their subjectivity. Nevertheless, these contentions do not formulate a compelling disputation. A substantial portion of globally recognized research enacts the philosophical heuristic of inference to the best explanation to fortify their hypotheses, like evolution and paleontology.

This article dissects documented case studies of animal emotions to encapsulate noteworthy contemporaneous findings. The principal purpose is to encourage researchers to pay closer attention to the aggregate suppositions of anecdotal attestations, philosophical ratiocinations, and empirical data in all research moving forward. Research concerning the emotional lives of animals should sustain despite the skeptic's dubious allegations of invalidity. This unique niche in biology is currently in its infancy despite its interminable potential for understanding other earthlings. Learning the experiences of animals has immense potential for animal activism, animal ethics, and the environment.

Systematizing Animal Emotions

Emotions are a complex neural phenomenon amidst no universally affirmed elucidation. For the study of animal emotions, they are the adaptive and integrative functions necessitous for survival (Panksepp, 1998). In sharp contrast to the stringent scrutinization of physiological responses to emotions, specialists should engage in the gauging of emotional expressions regarding their circumstantial advantages.

Another approach to this grueling enigma stems from behaviorism. Proponents of this view include René Descartes, B.F. Skinner, and John B. Watson who recommend the stimulus-response paradigm of behavioral interpretation. This school believes animals are organic automatons, reacting to particular stimuli based on learned behaviors, conditioning, and reinforcements. This minimalistic insolence questions animal emotions on the basis of a simpler response mechanisms existence (Watson, 1913). This design, due to its simplicity and ease of understanding, has consummated abundant approbation from the scientific community. Behaviorists view the interpretation of animal behaviors as unscientific and a direct ramification of motivated rationalizations precipitated by the unwarranted and blasphemous act of anthropomorphism (Masson & McCarthy, 1994). Contemporary research in neurobiology, psychology, and philosophy opposes behaviorism and argues the feasibility of objective data collection via the physiological responses to manufactured circumstances (Dawkins, 2000).

The complexity of emotions presents scientists with a new quandary. In engagement, it is quintessential to decipher emotional concepts before forming appraisals based on an emotional foundation. Investigators must differentiate primary emotions and secondary emotions. Primary emotions are inborn, the automatic inhibitions of the fight-or-flight mechanism in response to perceived danger. This instinctive response is essential for vestige and is a direct result of natural selection (Goldstein & Kopin, 2007). Secondary emotions are those whose experience relies on the cognitive evaluation of occurrences. These require higher mental processes and provide for variability and plasticity in behaviors. Historically, primary emotions are those shared with animals and secondary emotions as those which are not. (Viki et al., 2006).

The experience of emotions changes between species and chiefly depends on one's cognitive faculty. Experiences of emotions fluctuate and get molded by conscious reflections and evaluations. This assessment of stimuli is apparent in literature as subsisting in humans, but research must progress to authenticate its residence in animals. It is quintessential that science acknowledges the link connecting cognition and emotions for future integrity in research results (Paul, Harding, & Mendl, 2005).

Animals Living Emotionally

Much information is discoverable concerning the hidden perceptions of animals and their contingent potential to endure emotions. Research conducted in the preceding several decades has vindicated the permeance of animal emotions and has contributed considerable evidence. A wholesome starting locality is with primates because of their uncanny resemblance to humans. Primate investigations have rendered support for the presence of empathetic and altruistic characteristics.

One study exhibited these emotions in macaque (Macaca mulatta) monkeys. Pairs of macaques in transparent cells faced each other. With the jerk of a chain, one macaque would obtain food, but its comrade a three-second electrical shock. Evident was an inhibition to administering agony to a compatriot. On average, the macaques would persist up to 7.6 days with minimal provisions before inflicting the shock (Wechkin, Masserman, & Terris, 1964). A comparable study conducted on black rats (Rattus rattus) evoked extraordinary results, suggesting that they too work to diminish the distress of their kin. The potential of these behaviors in rodents (Rice & Gainer, 1962) embellishes the ubiquitous presence of animal emotions despite their negligible cognitive capabilities. This pronouncement additionally bolsters claims of adjustment in the range and austerity of emotions between species, rather than alterations in kind.

Support for the bearing of emotions in chimpanzees (Pan troglodytes) has great significance in the study of great apes. In one study, chimps from several families who were unfamiliar with one another would endeavor to alleviate the pain and suffering of another who was the victim of aggression. The consoling grew in direct correlation with harsher victimization (De Waal and Aureli 1996). Experts would likely encounter frustration beholding this incredulity even amidst humans.

Research has also afforded evidence of the potential of animals to undergo negative feelings like grief, despair, and depression. A chimp named Flint, who, following the death of his mother, withdrew from his group, halted eating and then perished soon after (Goodall, 1990). These feelings were also witnessed in a California sea lion mothers' (Zalophus californianus) audible utterances of lament as she watched her offspring get decimated by killer whales. Similar was the response of bottlenose dolphins (Tursiops truncatus) in their fruitless struggles to preserve the life of a stillborn infant (Bekoff, 2000b). In yet another example, African elephants (Loxodonta Africana) stood sentinel over their terminal toddlers for days in sorrow while different elephants shrieked and thrashed as they woke from their nightmares shortly after heeding their mother's death at the paws of predators (Choice Review, 2013).

Animals Living with Cognition

One of the most explicit exhibitions of animal cognition is in many human homes, the domestic dog (Canis familiaris). Scientists have ascertained that much of what a canine is feeling is evident in their posture, facial expressions, and other verbal and nonverbal communications. Their wagging tails also express many of their emotions (McConnell, 2006). Using these cues as an objective measure of what a dog is feeling, scientists were able to present provision for the presence of six consistent and stable "narrow" personality traits. These personality traits guard the actuality of cognition in dogs and are invaluable evidence of animal emotions. These six traits are curiosity & fearlessness, shyness & boldness, chase-proneness, sociability, aggressiveness, and playfulness (Svartberg & Forkman, 2002; Svartberg, Tapper, Temrin, Radesäter, & Thorman, 2005), which scientists discerned in a study conducted on 15,329 dogs of 164 different breeds.

Further data has uncovered the carriage of cognition in man's best friend from dogs demonstrating their capacity for emotional recognition both in their family and in those of humans. One study conferred dogs with faces denoting happiness or aggressiveness. When paired with a congruent or noncongruent vocalization, dogs looked at the congruent valence for significantly longer. These results further confirm animal cognition. The ability of dogs to delineate among emotional states; an ability long believed to be strictly human, is a milestone as it provides superior support for complex cognition in simpler brains (Albuquerque et al., 2016).

Chimpanzee cognition was also evident in a separate study. In this groundbreaking inquiry, chimps classified their experience of emotions by choosing relative facial expressions on cards. Ere their evaluation, chimps viewed numerous video clips of emotionally encumbered scenes. These involved displays of conspecifics in agony, abhorrent excursions to the veterinarian, and the application of needles to inoculate other chimps. On the positive end of the spectrum, they observed footage of their preferred refreshments, trinkets, and personages. The chimps were accurate in their judgments which parades their sophisticated perspicacity of the emotional significance marked by facial expressions. Throughout this study, scientists also documented the peripheral skin temperatures of the subjects, further betokening animal emotions (Parr, 2001).

Injunctions for Future Inquisition

Anthropomorphism has continually been the vassal of criticism and is exercised by skeptics as a medium for rejecting the validity of considerable research. Moving onward, scientists must master the recognition of this and combat the critical claims of fallacy skeptics promote. Due to the mysterious and bizarre lives of animal species on Earth, scientists must employ considerable time analyzing animals and strive to experience the world from their perspectives (Allen & Bekoff, 1997). Anthropomorphic rejections of research fail to advance science in this sphere and are deleterious to harmony on Earth.

Another impediment to the progression of research besieging animal emotions is the dread of potential “unscientific” damnation. These unsubstantiated assertions are an outgrowth of close-mindedness. The human interpretation and classification of animal experiences remain restricted by language, mandating engagement in anthropomorphism to access any insight into the private minds of different animals (Urquiza-Haas & Kotrschal, 2015). Simplistic attributions of biology, neurology, and physiology restrict our comprehension of complex functions due to their scarcity of context in humans, leaving only obscure and insignificant proclamations with no station in scientific discourse.

The scientific viewpoint on anthropomorphism in evaluating an animal's emotional experiences must face modifications, less all the research face falsehood. Anthropomorphism is the most communicative method of reporting and interpreting animal behaviors (Bekoff 2000). The sentiment of "critical anthropomorphism" is one form of mitigating cynical concerns. It suggests the utilization of an extensive assortment of informational sources in the generation of constructs which can be serviceable in the composition of prospective investigations (Burghardt, 1991).

The environments used by scientists to study animal behaviors and emotions must also face evaluation as there is an irrefutable influence of setting on psychology. Study naturalization is crucial to establishing a differentiation amid the actual lives of animals and the laboratory-induced lives of animals (Phillips, 1994). This paradigm shift's importance becomes compounded by the popular perception of stress in animals. Much of the research completed on laboratory animals must face careful evaluation as the same captivity believed to mitigate variability in data, is found to stress animals to the point of nullifying gathered data (T. Poole, 1997).

Future research must enable the cross-discipline collaboration of all domains concerned, including psychology and philosophy, as this provides further access to essential data. This collaborative venture between scholars of distinctive subjects has long been the cause of much of humankind's achievement in its scientific endeavors. Teamwork and cooperation are hallmarks of science and their utilization in the battle to understand animals should not be an innovative concept to any researcher. This interdisciplinary research must also target the study of more diverse taxa. Most contemporary research conducted is on dogs, primates, and cats. Science is an ever-evolving construct. The profound capacity to illuminate many of life's conundra is a keystone of human civilization and intellectual exploration.

Skeptics and Conclusory Thoughts

There is enormous controversy among segments of the scientific population concerning emotionality in animals. This disparity among scientists has been a prime motivator in the pursuance of knowledge and has resulted in much of the modern marvels taken for granted today. For flourishing study in this biological domain to be conducive, savants signifying skepticism need to contribute further justification, rather than deeming all advocacy as indigent based on complexity - the heart of science. This heuristic defense of theses has transpired toward the destruction of scientists for generations. It begets no station in contemporary science. Future research into the subject of animal emotions must account for the fact that there is almost nothing separating humans from animals. Researchers must enact the psychological principle of introspection to represent these traits in animals. The study of animal emotions is vital. All investigations mandate the utmost precaution and methodology.
