Richard Gerrit Coss is an American evolutionary psychologist and academic. He is a Professor Emeritus of Psychology at the University of California, Davis. [1]
Coss's research interest spans the field of behavioral evolution, with a particular focus on analyzing adaptive variation in antipredator behavior in different populations, and the impact of developmental, physiological, and neurobiological constraints on behavior. He is most known for his work on dendritic spine plasticity, and early contributions to the field of evolutionary aesthetic preferences. [2] [3] He has also authored and co-authored more than 130 peer-reviewed journal articles [4] and is the editor of the book Environmental Awareness: Evolutionary, Aesthetic and Social Perspectives. [5]
Coss is a Fellow of the Association for Psychological Science [6] and has been a member of numerous professional societies, including the Animal Behavior Society and the International Society for the Arts, Sciences and Technology. [7]
Coss was born on January 3, 1940, in Sanger, California. He is the son of Dr. Joe Glenn and Cornelia Geraldine Coss. After completing his early education, he enrolled at the University of Southern California and graduated in 1962 with a major in Industrial Design in the School of Architecture. Later in 1966, he earned his master's degree in design from the University of California, Los Angeles. In 1973, he completed his Ph.D. in Comparative psychology at the University of Reading in the UK, where Corinne Hutt was his dissertation adviser. For his dissertation, Coss conducted comparative research on the perceptual aspects of eye-like schemata in African jewelfish, mouse lemurs, [8] and autistic and typically developing children. [9]
Coss worked at Douglas Aircraft Company from 1962 to 1966. Afterwards, in 1966 he held an appointment as Research Director at the Compagnie de l'Esthetique Industrielle in France that developed the corporate identity for the Shell Oil Corporation. [10] Later, in 1986, he received a Fellowship by the NASA-Ames Research Center where he aided in evaluating ways to enhance space-station interiors for long-term habitation. [11]
Coss started his academic career in 1971, as a lecturer of design at the University of California, Los Angeles. After earning his Ph.D. in psychology, he became an assistant professor of psychology at the University of California, Davis. He was later promoted to associate professor in 1978 and became a professor of psychology in 1984. Since 2014, he has been serving as Professor Emeritus of Psychology at the University of California, Davis. [1]
At the beginning of his career, Coss focused his research on human-factors engineering with aerospace applications at Douglas Aircraft Company. In this context, he was appointed Project Engineer for a lunar-base design proposal to NASA using, for habitation, the spherical tanks manufactured for the second stage of the Saturn 5 lunar rocket. He has studied environmental aesthetics with respect to art and design. Later, his work was aimed at analyzing the antipredator behavior of several species in both field and laboratory conditions as model systems for understanding the development of innate behavior and aesthetic preferences in the context of human evolutionary history. He has published numerous articles in scientific journals and was the recipient of a patent for creating an apparatus for measuring pupillary dilation. [12]
Coss published a monograph in 1965 that described his visual perception research based on his theory that human ancestors were the prey of predators for a sufficient evolutionary time to engender innate recognition of predator features including two-facing eyes, sharp teeth, and claws. [13] Subsequently, he posited that recognizing such specific provocative shapes enhanced emotional arousal in a manner that have had an impact on works of art, [14] architecture, and product design. [15] [16]
While working on behavioral evolution, Coss identified that, despite having relaxed natural selection from snake predation for more than 300,000 years, [17] California ground squirrels are still capable of distinguishing their rattlesnake and gopher snake predators [18] as compared with Arctic ground squirrels that have lost this ability over 3 million years. [19] However, both species under prolonged relaxed selection have also lost their physiological resistance to rattlesnake venom. [20] [21] Following this research, he hypothesized that "evolved cognitive behavior in humans might persist for as long as 3 million years of relaxed selection" and to test this hypothesis he assessed the preschool children's selection of schematic trees as a form of refuge from predators and their overall refuge-seeking behavior on the playground, [22] particularly by investigating whether historical sexual-size dimorphism plays a role in influencing such behavior. [23] Subsequently, he examined the remembrances in pre-school children and adults of where "something scary" was located in their imagination relative to their beds at night [24] [25] producing findings which reinforced his argument that ancestral sources of natural selection might continue to bias modern aesthetic expression. [15]
Coss has been acknowledged for his substantial work on the innate pattern-recognition ability of different species. He elucidated that the salient effects of glossy and sparkling surface finishes attract infants and toddlers, [26] increasing the possibilities of endangering their life by drowning or suffocation from plastic bags [27] and described that viewing water has calming effects on adults. [28] Furthermore, he discovered that wild California ground squirrels, [29] white-faced capuchin monkeys, [30] and bonnet macaques are capable of recognizing their snake predators [31] by their size and scale patterns and, for bonnet macaques, their leopard predators by the spots on their coat. [32] [33] He later documented that young human infants are visually attracted reliably to snake-scale and leopard-spot patterns. [34]
Coss evaluated the provocative effects of two-facing eyes in humans and worked on the brain development [35] and behavior [36] of jewel fish which led him to a cover article in Science. [37] His joint study with A. Globus revealed that, due to social deprivation, the formation of dendritic branches in the optic tectum was arrested as was the experience-based shortening of dendritic spine stems. [38] Moreover, a single threatening experience shortened dendritic spine stems in the optic tectum, [39] [40] and enhanced fish behavioral excitability in a manner analogous to PTSD in humans. In related research, he examined developing honeybees and observed the shortening of dendritic spine stems on calycal interneurons with progressive nursing and foraging experiences [41] and also during their first orientation flight. [42]
Coss also conducted a research series to explore the sources of natural selection mediating human brain evolution. This led to experiments measuring flight distances of wild horses in Arizona and African zebras to an approaching human. [43] The lower fear of wild horses compared with zebras led to his hypothesis that extensive human hunting in Africa might have led to an arm's race for more competent hunting by humans to counter the increasingly evasive ability of wary prey. [44] Such an arm's race for enhanced visual and spatial competence in hunting might explain the enlargement of the human parietal cortex for accurate spear throwing as well the ability of modern humans to translate mental images into figurative art with significant cultural impact. In contrast, the lack of figurative art among European Neanderthals, who likely hunted less wary game with thrusting spears during the Middle Paleolithic, might account for the smaller size of the Neanderthal parietal cortex that limited their artistic expression. [45]
Apart from working on environmental aesthetics and behavioral evolution, Coss has contributed to animal welfare by examining the impacts of human intrusions in wildlife habitats. He advised graduate students studying African wild dogs and found that black-tailed deer in coastal California unaccustomed to humans were highly cautious when a human approached. [46] [47] While working in India, he studied the sleeping-site selection of bonnet macaques living near human settlements, [48] [49] and also examined the decline in tigers caused by the loss of palatable vegetation for large tiger prey. [50] Also in India, he studied crop-raiding by Asian Elephants, [51] and found that crop-raiding could be thwarted when elephant-activated tiger growls were played back to them. [52] [53] Another facet of his research on animal welfare involved the effects of crowding on brain development. Jewel fish crowded during development continue to school like younger fish [54] and their tectal interneurons look like those of younger fish, an indication that crowding restricts behavioral flexibility similar to that of developmental deprivation. [55] [56]
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved venom apparatus, such as fangs or a stinger, in a process called envenomation. Venom is often distinguished from poison, which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and toxungen, which is actively transferred to the external surface of another animal via a physical delivery mechanism.
The striatum or corpus striatum is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
The olfactory bulb is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.
The common garter snake is a species of snake in the subfamily Natricinae of the family Colubridae. The species is indigenous to North America and found widely across the continent. There are several recognized subspecies. Most common garter snakes have a pattern of yellow stripes on a black, brown or green background, and their average total length is about 55 cm (22 in), with a maximum total length of about 137 cm (54 in). The average body mass is 150 g (5.3 oz). The common garter snake is the state reptile of Massachusetts.
Ophidiophobia /əˌfɪdioˈfo͡ʊbiə/ is fear of snakes. It is sometimes called by the more general term herpetophobia, fear of reptiles. The word comes from the Greek words "ophis" (ὄφις), snake, and "phobia" (φοβία) meaning fear.
Interneurons are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons. Interneurons are the central nodes of neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS). They play vital roles in reflexes, neuronal oscillations, and neurogenesis in the adult mammalian brain.
Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation. It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator. Often, an animal's escape response is representative of an instinctual defensive mechanism, though there is evidence that these escape responses may be learned or influenced by experience.
Interspecies communication is communication between different species of animals, plants, or microorganisms.
The basal ganglia form a major brain system in all vertebrates, but in primates there are special differentiating features. The basal ganglia include the striatum, pallidus, substantia nigra and subthalamic nucleus. In primates the pallidus is divided into an external and internal globus pallidus, the external globus pallidus is present in other mammals but not the internal globus pallidus. Also in primates, the dorsal striatum is divided by a large nerve tract called the internal capsule into two masses named the caudate nucleus and the putamen. These differences contribute to a complex circuitry of connections between the striatum and cortex that is specific to primates, reflecting different functions in primate cortical areas.
In the hippocampus, the mossy fiber pathway consists of unmyelinated axons projecting from granule cells in the dentate gyrus that terminate on modulatory hilar mossy cells and in Cornu Ammonis area 3 (CA3), a region involved in encoding short-term memory. These axons were first described as mossy fibers by Santiago Ramón y Cajal as they displayed varicosities along their lengths that gave them a mossy appearance.
Accident-proneness is the idea that some people have a greater predisposition than others to experience accidents, such as car crashes and industrial injuries. It may be used as a reason to deny any insurance on such individuals.
The Mauthner cells are a pair of big and easily identifiable neurons located in the rhombomere 4 of the hindbrain in fish and amphibians that are responsible for a very fast escape reflex. The cells are also notable for their unusual use of both chemical and electrical synapses.
Primate cognition is the study of the intellectual and behavioral skills of non-human primates, particularly in the fields of psychology, behavioral biology, primatology, and anthropology.
Dario Maestripieri is an Italian behavioral biologist who is known for his research and writings about biological aspects of behavior in nonhuman primates and humans. He is currently a professor of Comparative Human Development, Evolutionary Biology, and Neurobiology at The University of Chicago.
Addiction is a state characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. The process of developing an addiction occurs through instrumental learning, which is otherwise known as operant conditioning.
Donald H. Owings was a professor of psychology and faculty member of the Animal Behavior Graduate Group at the University of California, Davis. His research focused on ground squirrels, in particular, their interactions with predators such as rattlesnakes; and, more generally, on concepts of communication within and between species. In 1994, he was elected as a fellow of the animal behavior society and in 2010 he received the Exemplar Award for mentoring graduate students.
In biology, paternal care is parental investment provided by a male to his own offspring. It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. Paternal care may be provided in concert with the mother or, more rarely, by the male alone.
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non-copulatory mounting, oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub participants, as well as sex with dead animals.
Displaced aggression, also referred to as redirected aggression, occurs when an animal or human is fearful or agitated by external stimuli, a provocation, or perception, but is unable or unwilling to direct their aggression toward the stimulus. The aggressor may direct aggression toward whoever is nearest. The behavior is more common in cats than it is in dogs. In certain species of monkeys anger is redirected toward a relative or friend of an opponent. In cichlid fish, it may be used to manage conflict within the group. Displaced aggression is experienced by humans and animals.
