Examining the Strengths and Weaknesses of Applying Evolutionary Theory to Understand Human Behaviour. In the case of evolutionary theory, its many false predictions reveal that the theory is not motivated by the science and that the textbook claim that evolution is a fact does not come merely from empirical evidence (see Conclusions). To begin with, scientific usage of "theory" differs from everyday usage.In common usage a theory is simply a conjecture. Moreover, Barrett cited evidence that negative dreams and their associated handicapping in the waking state do not enhance fitness: “Cheerful, confident-appearing people seem to have the advantage in mate selection and most other types of interactions” (p. 137). Theory of evolution Evolution of human beings over millions of years from ape-like ancestors. McNamara's (2004) theory that dreams produce images that are used in rituals and religious ceremonies is supported by the historical record about Native American tribes in the 17th and 18th centuries provided by Jesuit missionaries, who described the centrality of sacred dream images in the cultural and religious life of the tribal members. It doesn't seem necessary to insist that these signals are also costly in the sense of being negative. Persons with autism spectrum disorder (ASD) experience problems with human relatedness and meaningful social interactions. That's because sometimes there's a fine line between strengths and weaknesses. This is further supported by Franklin and Zyphur (2005), who argued that increased activity of the anterior cingulate during REM involves cognitive functions that are implicated in social interactions: “These data suggest that aspects of cognition centering on the processing of social information are strongly activated during REM sleep” (p. 69). I had my own insight into this a few years ago when one of my positive psychology colleagues urged me to join a gym and lose weight. According to McNamara, when using these scoring rules, about 80% of dreams of men and women contain negative emotions. The evolution of management thought, 6th ed. … Morewedge and Norton (2009) found that in addition to creating emotions that carry over into waking life, dreams impact many people's waking feelings, thoughts, and actions more than actual waking experiences do: We suggest, however, that people do not merely lend the same amount of credence to thoughts that occur in dreams as thoughts that occur while awake but actually treat the content of their dreams as more meaningful than the content of similar waking thoughts. McNamara (2004) posited that REM dreams create costly and hard-to-fake signals that nonetheless enhance communication, increasing the dreamer's overall fitness. (, Kozlov, S.V., Bogenpohl, J.W., Howell, M.P., Wevrick, R., Panda, S., Hogenesch, J.B. and Stewart, C.L. Participation in these ceremonies and rituals, according to McNamara, could be used to gauge the commitment of tribal or community members. McNamara then contradicted this statement while discussing the emotional impact of REM dreams: “REM-related production of emotional states and costly signals would influence dream content and the display of emotional signals the person emits the next day, whether or not the person remembered any dream that morning” (p. 163). Whether or not these signals are predominantly negative is less certain. The theory is attributed to the following strengths and weaknesses. The theory – that liberal democracies tend to go to war less frequently than other forms of state governments – is a controversial one, with both strengths and weaknesses, supporting and weakening points, although the academic work surrounding the debate has shown the scales to be tipped towards support for the theory.

Problems for TE are not restricted to irreconcilable differences between evolutionary theory and the first two chapters of Genesis. In addition to regulating sleep and wakefulness, orexin is involved in regulation of food intake and male fertility. In situating his theory of REM sleep dreaming within evolutionary theory, McNamara (2004) provided a detailed description of the appearance of REM and NREM sleep states in mammals and argued that these distinct sleep states emerged from a combination of sleep states that first appeared in monotremes. Bowlby’s theory is sometimes referred to as an evolutionary theory. Agreeing, Fosshage (2007) argued that dreams function to regulate affect, and that visual images evoke more affect. The evolutionary theory like any other sociological theory is strived with strengths and weaknesses. Contemporary Psychodynamic Theories I have read and accept the terms and conditions. This essay will investigate the evolutionary psychology theory and the Attachment theory and how they relate to other theories. According to McNamara and Szent-Imrey: “Dreams can also function to facilitate production of signals when they produce some daytime effect such as a memory or mood (or both) or a behavior that communicates a message to an observer” (p. 29). Central to McNamara's (2004) costly signaling theory of REM dreams is the impact the dream continues to exert in the waking life of the individual. These included dreams that increased transcendent awareness and mundane dreams with an absence of any intense emotion or aggression. By identifying them, I am able devise a plan to improve my areas of weakness, while using my strength to my advantage. Many weaknesses listed for convenience here. To the extent that these genes are imprinted, these effects arise in a context of genomic conflict, lending credence to McNamara's (2004) evolutionary psychology theory of dreaming. Although this seems plausible, he did not present any evidence of an exchange of dream elements as signals. Traits which offered our ancestors a survival or reproductive advantage in our environment of evolutionary adaptation (EEA) would be passed on to offspring and as a result … There is strong evidence that REM sleep and dreaming is biologically costly, and that the REM sleep state produces hormonal, neurological, and biochemical signals. Please read and accept the terms and conditions and check the box to generate a sharing link. McNamara (2004) described genes that regulate sleep, including separate genes that regulate REM and NREM, and presented information that indicates that some genes regulating REM are imprinted by paternal alleles, and some genes regulating NREM are imprinted by maternal alleles, lending support to his theory that genomic conflict influences the interactions of REM and NREM sleep. Furthermore, in discussing genetic determinants of sleep, McNamara described sleep behavior that has been observed in fruit flies. They can dictate the syllabus. Valli and Revonsuo (2007) argued that REM sleep and dreaming are products of evolution: Dreaming and its closest physiological correlate, the REM state of sleep, are energetically costly, and natural selection does not retain costly characteristics unless they provide advantages. From an ethnographic perspective, Lohman (2007) provided a detailed description of the role of dreams in shaping cultural and social interactions in a variety of traditional cultures in the modern world. His evolutionary theory of dreaming is based largely on the physiological costs of REM, as well as on the handicapping properties of REM dreams, which he related to the destabilizing effect of REM on the ANS and other physiologic systems, and the emotions produced by the parts of the brain that are activated during REM, respectively. Not only are aspects of maternal behavior caused by imprinted genes, but also maternal behavior causes epigenetic effects in the offspring, which are then transmitted to future generations (Champagne, 2008; Champagne and Meaney, 2007; Weaver et al., 2004). Evolutionary psychology provides the conceptual tools for emerging from this fragmented state BUT problem with seeing everything as an adaptation. He theorized that this signaling would follow the rules of animal communication and that if REM and NREM interact through signaling in physiological systems, then REM and NREM could interact in sleeping to exchange signals that affect the structure, imagery, and content of dreams during REM and NREM sleep. There is strong evidence that emotions affect cooperation, but less evidence that negative emotions are any more effective than positive emotions in this respect. In addition to mammals, sleep has been characterized in genetic model organisms, ranging from the nematode … The other type of costly signal is the production of images that are used to construct religious ceremonies and rituals in cultures that view dreams as sacred. As with the strengths, each weakness is accompanied by a brief description to help you decide whether that particular flaw suits you or not. If you have the appropriate software installed, you can download article citation data to the citation manager of your choice. They stated: “Thus, it appears advantageous to be able to create vivid representations in the mind's eye of various scenarios, which in fact, is what dreaming entails” (p. 65). Just to add a bit to Ian's three points and the other excellent answers here: The basic rule for evolution is: don't be any stronger than you need to be. Strengths and Weaknesses Strengths: We now have a clear set of established mid-level properties of human language, and a clear set of established tests. Since human beings have never lived during a time when the earth was entirely covered by water, to avoid conflict with scientific consensus TE proponents will have to treat this story as a myth as well. Evolutionary theory cannot be used to justify or condemn human action (although it may explain the origins and causes of such action). For more information view the SAGE Journals Article Sharing page. Although this seems plausible, McNamara does not offer any evidence to support this theory. Another paternally expressed gene that affects hypothalamic function is Magel2, as described by Kozlov et al. Through DNA methylation, effects of maternal behavior change the oxytocin-estrogen interactions, estrogen receptor levels in the hypothalamus, and oxytocin receptor binding in the hypothalamus (Champagne, 2008; Champagne and Meaney, 2007). In relation to cooperation they stated: “Natural selection will have favored psychological attributes that enhance the individual's ability to engage in, and profit from, cooperative enterprises” (p. 8). Even so, he maintained his claim about the negative emotional content of dreams: Dreams more often involve negative than positive emotion. As described in these studies, genomic conflict plays a role in growth, development, sleep regulation, maternal behavior, and maternal-infant interactions, supporting McNamara's claim for the role of genomic conflict in REM and NREM sleep and dreams. McNamara posited that dreams and religion are interconnected in a way that promotes cooperation: “Religion may call on the dream as a source of signals and images that are costly and that will work to establish cooperation in a local group of people and to punish potential free riders” (p. 166). History of Lamarckism, an early theory of organic evolution. He stated that it has been found that REM sleep is important to the development of lateral geniculate neurons, which are implicated in the development of the visual system. Conversely, infant rats prefer to nurse while they are in REM sleep. 806 8067 22, Registered office: International House, Queens Road, Brighton, BN1 3XE, Strengths and Weaknesses of the Cosmological Argument, See all Religious, Moral and Philosophical Studies resources », See all Christianity: Belief and Science resources », Should Creationism be taught in schools? You can be signed in via any or all of the methods shown below at the same time. The strengths and weaknesses of this model are then evaluated in terms of its consonance with measurable neurological and biological properties of dreaming, its fit within the tenets of evolutionary theories of dreams, and its alignment with evolutionary concepts of cooperation and spirituality. Their emphasis on evolutionary process had been fruitful. For example, when rats and monkeys are separated from their mothers under experimental conditions, there is an initial increase in their REM times, followed by a dramatic reduction. (2005) found that in mice, grbrb3, which codes for GABA receptor, is imprinted, affecting EEG and behavior. Genesis 6-9 describes the well-known story of the Flood. There are many notable examples of psychological theories with evolutionary bases, such as Bowlby’s (1969) model of attachment, yet these are often isolated examples. It is important to note that McNamara argued that it is not REM sleep per se that constitutes a signal in the waking state; rather, the emotions experienced during REM dreams result in residual affect or moods that serve as hard-to-fake signals, enhancing social interaction, and REM dreams in relation to spiritual practices provide symbols that are hard to fake, increasing cooperation and unity among the members of the group who adhere to the spiritual practice. Barrett posited that in addition to providing images for rituals and religious ceremonies, dreams also provided other useful images: “Modern hunter-gatherers, and less industrialized societies in general, often teach explicitly that dreams can provide inspiration or solve problems” (p. 147). The idea that brain development and function are influenced by imprinted genes is supported by Wilkinson, Davies, and Isles (2007) who found that maternally expressed genes influence higher cognitive functions, whereas paternally expressed genes influence emotional and autonomic functions: One interpretation of the data might be that the maternal interests are, in broad terms, mediated by neurodevelopmental effects on ‘higher’ cognitive systems, whereas the paternal interests are mediated by effects on brain systems that sub-serve ‘emotional’ or ‘autonomic’ functions” (p. 833).
