CONSCIOUSNESS SUBMITTED TO:- MISS ISHA PAUL SUBMITTED BY:SHRADHA GAUR MA I PRESENTATION OUTLINE Definition and characteristics History in brief Modern theories of consciousness Waking states of consciousness: Controlled and Automatic processing, Self-Awareness, Effects of SelfAwareness. Consciousness George Miller wrote in 1962, "Consciousness is a word worn smooth by a million tongues.” What he meant was that, the term means many different things to many different people, and no universally agreed "core meaning" exists. This uncertainty about how to define consciousness is partly brought about by the way global theories about consciousness have intruded into definitions. Consciousness In classical Indian writings such as the Upanishads, consciousness is thought to be the essence of Ātman, that is ultimately identified with Brāhman—a pure, transcendental, subject-object-less consciousness. (Sen,2008). In the classical Western tradition, "substance dualists" such as Plato and Descartes bifurcated the universe, believing it to consist of two fundamental kinds of stuff, material stuff and the stuff of consciousness (a substance associated with soul or spirit). History The concept of consciousness dates back to the pre 18th century era. Philosophers like Rene Descartes, in defining consciousness, focused on the subjective experience of the mind. One of his famous quotes is ‘I think therefore I am”. Then came the 18th century theorists one of whom was Wilhelm Wundt who used the term in the very definition of psychology- the ‘study of mind and consciousness’. He used the introspective method to study consciousness. However, soon came Watson’s behaviorism which out rightly rejected the study of consciousness because they believed that for psychology to become a science, it’s data must be objective and measurable. History However, soon psychologists began to realize that various aspect of consciousness are too important to be neglected. This revived focus on consciousness and led to the development of theories. What is consciousness? Consciousness is defined as our moment-to-moment awareness of ourselves and our environment. (Begley,1978) Another way of defining consciousness could be- all the sensations, perceptions, memories and feelings we are aware of in any instant. (Bisiach,1980 ) Another definition could be the phenomenal experience of sensation, action and thought. What is consciousness? According to Niedermeyer (1967), to be conscious is to be aware of things and the things can be objects outside ourselves, or in our own memories, thoughts and feelings. All these definitions, however, identify only one aspect of consciousness and ignore the fact that we are also conscious when we try to solve a problem or deliberately select one course of actions over others in response to environmental circumstances. Consciousness involves: What is consciousness? 1. 2. Monitoring ourselves and our environment so that perceptions, memories and thoughts are represented in awareness, and Controlling ourselves and our environment so that we are able to initiate and terminate behavioral and cognitive activities. (Kihlstrom,2007) Consciousness involves both the feeling of awareness and the content of awareness (Chalmers,1995,1996). Characteristics of consciousness Consciousness is: 1. Subjective and private: Other people cannot directly know what reality is for you, nor can you enter directly into their experience. 2. Dynamic(ever changing): We drift in and out of various states throughout each day. Although the stimuli of which we are aware constantly change, we typically experience consciousness as a continuously flowing “stream” of mental activity, rather than as disjointed perceptions and thoughts(James, 1890/1950). Characteristics of consciousness 3. Self-reflective and central to our sense of self: the mind is aware of its own consciousness. Thus, no matter what your awareness is focused on—a lovely sunset or an itch on your back—you can reflect upon the fact that “you” are the one who is conscious of it. Finally, consciousness is intimately connected with the process of selective attention. Characteristics of consciousness William James noted that “. . . the mind is at every stage a theatre of simultaneous possibilities. Consciousness consists in . . .the selection of some, and the suppression of the rest by the . . . agency of Attention”(1879, p. 13). Selective attention focuses conscious awareness on some stimuli to the exclusion of others. If the mind is a theatre of mental activity, then consciousness reflects whatever is illuminated at the moment the “bright spot on the stage”—and selective attention is the “spotlight” or mechanism behind it(Baars, 1997). Automatic and Controlled Processing Many cognitive processes may be differentiated in terms of whether they do or do not require conscious control. Two kinds of processes may take place: Automatic: Automatic processing uses very little of our information-processing capacity and seems to occur in an automatic manner with very little conscious awareness on our part. Several different activities, each under automatic control, can occur at the same time. For example- Automatic and Controlled Processing Brushing your teeth while talking to your mother. Driving your car while listening to music and singing along. Writing your name or giving your signatures while talking to someone, or listening to music or thinking about something else. Automatic processing occurs most often when we carry out routine actions or well-learned tasks, particularly under constant or familiar circumstances (Ouellette & Wood,1998). Automatic and Controlled Processing Through years of practice, typists, athletes, and musicians program themselves to execute highly complex skills with a minimum of conscious thought. According to Posner and Snyder, 1975), three attributes characterize automatic processes:1) They are concealed from consciousness 2) They are unintentional 3) They consume few attentional resources. Automatic and Controlled Processing However, automatic processing has a key disadvantage too. It can reduce our chances of finding new ways to approach problems. Though it is rapid and efficient, it can be relatively inflexible precisely because it is so automatic. Controlled : Controlled processing involves more effortful and conscious control of thought and behavior. You direct careful attention to the task at hand and concentrate on it. Automatic and Controlled Processing Processing of this type consumes significant cognitive resources; as a result, only one task requiring controlled processing can usually be performed at a time. Therefore, controlled processing is slower than automatic processing, but is more flexible and open to change. In sum, both play an important role in our efforts to deal with information from the external world. Automatic and controlled processing are not hard and fast categories, but rather ends of a continuous dimension. Automatic and Controlled Processing In fact, many tasks that start off as controlled processes eventually become automatic ones. For example, learning to speak a foreign language, is initially a controlled process because you need to translate word for word from your native tongue. Eventually, however, you learn it and speaking in that language comes naturally to you. This process is termed as Automatization.
