evolutionary theory of emotion

Are there cues in the lion's behavior that indicate whether it has eaten recently, and so is unlikely to be predatory in the near future? With the preceding view of emotions in mind, in the next section we will outline the evolutionary and cognitive principles that led us to it (detailed arguments for these positions can be found in Tooby & Cosmides, 1992, 1990a, and 1990b, and in Cosmides & Tooby 1987, 1992, 1997). Evaluating entire chains as units is not sufficient, because each item in a chain (staying behind from the hunt, making a tool, borrowing materials from a friend, etc.) For example, there should be algorithms in the auditory system that, upon detecting the fear signal (see (6)), reset signal detection thresholds, increasing acuity for predator-relevant sounds. It is difficult to sleep when your heart and mind are racing with fear, and this is no accident: disastrous consequences would ensue if proprioceptive cues were activating sleep programs at the same time that the sight of a stalking lion was activating ones designed for predator evasion. 1995 / 2000. The class of events captured by "unexpectedly positive" is extremely broad, general, and have only a few additional properties in common. Depression should be precipitated by (1) a heavy investment in a behavioral enterprise that was expected to lead to large payoffs that either failed to materialize or were not large enough to justify the investment; or (2) insufficient investment in maintaining a highly valued person or condition that was subsequently lost (possibly as a consequence); or (3) gradual recognition by situation-detectors that one's long-term pattern of effort and time expenditure has not led to a sufficient level of evolutionarily meaningful reward, when implicitly compared to alternative life paths (the condition of Dickens' Scrooge). Maynard Smith, J. Imposed conceptual frameworks: Emotions should prompt construals of the world in terms of concepts that are appropriate to the decisions that must be made. Emotion: Theory, Research, and Experience, Volume 1: Theories of Emotion, presents broad theoretical perspectives representing all major schools of thought in the study of the nature of emotion. For example, the condition of having a mate plus the condition of one's mate copulating with someone else constitutes a situation of sexual infidelity: a situation that has recurred over evolutionary time, even though it has not happened to every individual. Diego, CA: Academic Press. Decreased social status. 1983. For example, imagining the death of your child can call up the emotion state you would experience had this actually happened, activating previously dormant algorithms and making new information available to many different mechanisms. 1985. Fear can be evoked by two systems in the brain, both involving the thalamus and the amygdala: one old, short and fast, the other more recently evolved, more circuitous and slower. From this perspective, one can define the mind as a set of information-processing procedures (cognitive programs) that are physically embodied in the neural circuitry of the brain. Undoubtedly they sometimes are. Again, a superordinate program is needed that coordinates these components, snapping each into the right configuration at the right time. The second of the principles is that of antithesis. Not only can humans articulate and share their emotions, they can use their experiences to foresee and take appropriate action in future experiences. M. Lewis & J. M. Haviland-Jones, Editors. This article considers the implications of natural selection for several classic questions about emotions and emotional disorders. The logic of social exchange: Has natural selection shaped how humans reason? According to this theory, emotions are composed of two factors: physiological and cognitive. Individuals often behave as if they are in the grip of an emotion, while denying they are feeling that emotion. These generate correct (or, at least, adaptive) outputs that would not be warranted on the basis of perceptual data processed through some general-purpose decisional algorithm. Tomaka, J., Blascovich, J., Kibler, J., Ernst, J. Selection detects the individually unobservable. Typically, the goal is to explain why emotions are present in humans today by referring to natural selection that occurred some time in the past. Emotion programs have evolved to take such elements into account, whether they can be perceived or not. Psychophysiology of emotional and memory networks in posttraumatic stress disorder. According to modern evolutionary theory, different emotions evolved at different times. Shepard, R. N. 1987. An evolutionary perspective makes clear why the cognitive or computational level of description is more than an analogy. Those alterations that improve the machine's ability to solve reproduction-promoting tasks (compared to the earlier model design feature) will increase their own frequency over the generations, until (usually) they become universally incorporated into the species design. Consequently, the key to unlocking and activating many complex evolved decision and evaluation programs was chained to the present: to being in an environment displaying specific perceptually detectable cues and cue constellations (sweetness, predators, running sores, emotion expressions). Bodily changes in pain, hunger, fear and rage. - Evolution, Emotion, and Reason: Emotions, Part I Overview. Selection will not shape decision rules so that they act solely on the basis of what is most likely to be true, but rather on the basis of the weighted consequences of acts given that something is held to be true. Even if the algorithms assign a 51% (or even 98%) probability to the tree being predator-free, under most circumstances an evolutionarily well-engineered decision rule should cause you to avoid the tree - to act as if the predator were in it. Far from being internal free agents, these programs have an unchanging structure regardless of the needs of the individual or her circumstances, because they were designed to create states that worked well in ancestral situations, regardless of their consequences in the present. How did emotions arise and assume their distinctive structures? These are emotion programs that have appeared puzzling from a functional perspective because the feelings they engender interfere with short-term utilitarian action that an active organism might be expected to engage in. Negative emotions like fear trigger the “fight or flight” response necessary for dealing with danger. An evolutionary perspective leads one to view the mind as a crowded zoo of evolved, domain-specific programs. Charles Darwin proposed that emotions evolved because they allowed humans and animals to survive and reproduce. Signal detection thresholds shift: Less evidence is required before you respond as if there were a threat, and more true positives will be perceived at the cost of a higher rate of false alarms. For this reason, evolutionary psychology is both environment-oriented and past-oriented in its functionalist orientation. There are six basic human emotions: anger, fear, surprise, sadness, happiness, and disgust. Paradoxically, grief provoked by death may be a byproduct of mechanisms designed to take imagined situations as input: it may be intense so that, if triggered by imagination in advance, it is properly deterrent. It is also important to understand that evolutionarily recurrent situations can be arrayed along a spectrum in terms of how rich or skeletal is the set of probabilistically associated elements that defines the situation. Evolutionary approaches to the emotions have traditionally focused on a subset of emotions that are shared with other species, characterized by distinct signals, and designed to … The evolutionary theory of emotions is supported by _____. (1994). New York: Academic Press. The role of imagery and emotion in planning: Imagery is the representation of perceptual information in a format that resembles actual perceptual input. Note that a coma is not a physically mandated state of paralysis: it is a computational state (technically, "a state of unconsciousness from which the patient cannot be roused" (Miller, 1976, p. 46), or "unarousable unresponsiveness" (Berkow, 1992, p. 1398): It occurs even when there has been no damage to the motor system. The effort that it takes to perform given tasks will shift accordingly, with things being easier or more effortful depending on how appropriate they are to the situation reflected by the emotion (Tooby & Cosmides, 1990a). Odd places that you normally would not occupy - a hallway closet, the branches of a tree - suddenly may become salient as instances of the category "safe" or "hiding place". or What is the relationship between others' facial expressions and their mental states? Why? Is there somewhere I can go where I can see and hear what is going on better? and on to frontal association areas, where appraisal occurs. The payoff of each "factor of production"-of each act in the sequence-must be computed before an agent could determine whether the whole sequence was worthwhile. Evidence of the presence (or absence) of high degrees of coordination between adaptive problems and the design features of putative adaptations allows researchers to distinguish adaptations, byproducts, and noise from one another (Williams, 1966; Cosmides & Tooby, 1997). If the EEA imposes certain evolutionarily repeated games, then the "strategies" (the evolved cognitive programs that govern behavior in those contexts) should evolve in the direction of choices that lead to the best expected fitness payoffs. Journal of Personality & Social Psychology, 73, 63-72. Question 1 5 pts Describe the connection between emotion and stress. Humans viewing expression of pride automatically assign a higher social status to such individuals than to those expressing other emotions.[6]. When selection is neutral, the signs of an emotion should only be the byproducts of whatever is necessary to run the emotion program, without any selection to make the cues informative. (Prioritizing algorithms can be thought of as a supervisory system operating over all of the emotions.). Describe evolutionary theories of emotion and how they support the connection between emotion and stress. If our psychological mechanisms were not using present outcomes to assign a common internal currency of hedonic weights to classes of acts, there would be no function to suffering, joy, and so on. Thus, the claim that emotion is computational does not mean that an evolutionary psychological approach reduces the human experience to bloodless, affectless, disembodied ratiocination. Signals dominance. According to the American Psychological Association (APA), emotion is definedas “a complex reaction pattern, involving experiential, behavioral and physiological elements.” Emotions are how individuals deal with matters or situations they find personally significant. Introduction to Lecture 00:51 Chapter 2. Adaptive problems. The evolutionary designs of all modern species, including humans, use distinctive constellations of perceptual inputs as signals of states of affairs (for the rabbit, the outline of a hawk silhouette means a hawk is swooping in). Other goals and the computational systems that subserve them are deactivated: You are no longer hungry; you cease to think about how to charm a potential mate; practicing a new skill no longer seems rewarding. (Ed.) Little experimental work has been done to extend the theory, however. The single most limiting resource to reproduction is not food or safety or access to mates, but what makes them each possible: the information required for making adaptive behavioral choices. The overall result of these selection pressures would be that some emotions would evolve to be automatically broadcast, others would not evolve a signal, and a third category would evolve circuits that regulate the broadcast to some extent, just as it is in language. More specifically, however, mechanisms proximately involved in the generation of actions (as opposed to processes like face recognition that are only distally regulatory) should be very sensitive to emotion state. Strong evidence for universals in facial expressions. (For detailed arguments, both on the weakness of domain-general architectures and on the many advantages of architectures that include a large number of domain-specific computational devices, see Cosmides & Tooby, 1987, 1994; Tooby & Cosmides, 1990a, 1992). A key task for psychologists, then, is to discover, inventory and map the "circuit logic" of the collection of programs that constitute the human mind, and relate how that adaptive logic maps onto the suite of informational problems faced by our hunter-gatherer ancestors. However, unlike most of Darwin’s other work, this area of inquiry lay dormant for almost 100 years. Psychological Bulletin. According to modern evolutionary theory, different emotions evolved at different times: primal emotions, filial emotions and, later on, social emotions. In The latest on the best: Essays on evolution and Optimality, J. Dupre (Ed.). Affective coloration of events and stimuli as a form of learning: A behavioral sequence is composed of many acts. - Evolution, Emotion, and Reason: Emotions, Part I Overview. Emotions can be explained as specialized states, shaped by natural selection, that increase fitness in specific situations. Gould, S.J. If the threat is real, and the ambush occurs, the victim may experience an amygdala-mediated recalibration (as in post-traumatic stress disorder) that can last for the remainder of his or her life (Pitman & Orr, 1995). In The cognitive neurosciences, M. S. Gazzaniga (Ed.). Primal emotions, such as fear, are associated with ancient parts of the brain and presumably evolved among our premammal ancestors. But programs for inferring emotion states from facial displays would not have evolved unless doing so created a net advantage for the inferer, suggesting that these inferences were warranted more often than not. Any controllable biological process that, by shifting its performance in a specifiable way, would lead to enhanced average fitness outcomes should have come to be partially governed by emotional state (see (7) above). What ultimately happens to each mutation is shaped both by chance and by the stable consequences the mutation has on the design of the organism -- selection. What someone learns from stimuli will be greatly altered by emotion mode, because of attentional allocation, motivation, situation-specific inferential algorithms, and a host of other factors. A homunculus scans the environment and freely chooses successful actions in a way that is not systematic enough to be implemented by a program. Indeed, recalibrational emotion programs are emotion programs such as guilt, grief, depression, shame, and gratitude, whose primary function is to carry out such recomputations (Tooby & Cosmides, 1990a), rather than to orchestrate any short run behavioral response. For example, the negative effects of incestuous conceptions are difficult for any individual to observe in the absence of a modern controlled study with numerous participants, much less integrate rationally into one's motivational system. Darwin himself began the investigation into the relationship between emotions and evolution with The Expression of the Emotions in Man and Animals in 1872. NY: Oxford. (1997). Jealousy, guilt, or boredom are all genuine emotions lacking distinctive signals. A child did not have to wait to be ambushed and killed in the dark to prudently modulate her activities. Evolutionary psychologists consider human emotions to be best adapted to the life our ancestors led in nomadic foraging bands. Ekman noted that while universal expressions do not necessarily prove Darwin's theory that they evolved, they do provide strong evidence of the possibility. Others indicated sexual attractiveness (Symons, 1979; Buss 1994). Jealousy, for example, involves several sets of recalibrations (e.g., dimunition in estimate of own mate value, diminution of trust). ), The adapted mind. Consequently, each decision about where to allocate assistance depends on inferences about the relative weights of these variables. To be moved with gratitude, to be glad to be home, to see someone desperately pleading, to hold one's newborn baby in one's arms for the first time, to see a family member leave on a long trip, to encounter someone desperate with hunger, to hear one's baby cry with distress, to be warm while it is storming outside: these all mean something to us. There should be a larger set of emotions that have no automatic display. 3 SURVIVAL … & Cosmides, L. 1990a. They take the cues in (3) as input. Such processes include: Goals: The cognitive mechanisms that define goal-states and choose among goals in a planning process should be influenced by emotions. The brain came into existence and, over evolutionary time, accreted its present complex structure because, in ancestral populations, mutations that created or altered cognitive programs such that they more successfully carried out adaptively consequential information-processing tasks were differentially retained, replicated, and incorporated into our species' neural design. Feelings of fear compel people to either fight or flee the source of danger. Whereas other parts of the body were designed for lifting loads, grinding food, chemically extracting nutrients, and so on, the brain was designed by evolution to use information derived from the environment and the body to functionally regulate behavior and the body. Information-processing programs - food preferences and aversions, or rules for inferring emotions from facial expressions - acquired one set of design features rather than many others because the retained features better computed solutions to these information-processing problems. However, many important features of the world cannot be perceived directly. On the emotions as guarantors of threats and promises. Recent evolutionary theories of emotion also consider emotions to b… Evolutionary psychology is not a specific subfield of psychology, such as the study of vision, reasoning, or social behavior. For example, predators use darkness and cover to ambush. 115: 268-87. Recent evolutionary theories of emotion also consider emotions to be innate responses to stimuli. Evolutionary psychology is an approach to the psychological sciences in which principles and results drawn from evolutionary biology, cognitive science, anthropology, and neuroscience are integrated with the rest of psychology in order to map human nature. Smith and Ellsworth, 1985, or Roseman, 1996) have emerged that attempt to create a full account of emotion formulation. Cross-cultural studies and studies on the congenitally blind have found that these groups display the same expressions of shame and pride in situations related to social status. Emotions and personality also fall into this category, although their evolution is much more complex than basic instinctual survival skills. Thinking  - June 6, 2019. The study of the evolution of emotions dates back to the 19th century. Robert Plutchik's PSYCHOEVOLUTIONARY THEORY OF BASIC EMOTIONS Postulates 1 ANIMALS AND HUMANS The concept of emotion is applicable to all evolutionary levels and applies to all animals as well as humans.
