  1. 1. MINDDR. JAMES Malce ALO
  2. 2. MIND Is the complex of cognitive faculties  mental processes that enables:  1. Consciousness – quality/state of being aware  2. Thinking – act of thinking that includes:  Cognition - awareness  Sentience – ability to feel, perceive, be conscious  Imagination – ability of mind creativity2/15/2013 drjma
  3. 3.  3. Reasoning  capacity of human being to make sense of things  Establish and verify facts  Change or justify practices, beliefs, & institutions  4. Perception  is the organization, identification, and interpretation of sensory information in order to fabricate a mental representation through the process of transduction, which sensors in the body transform signals from the environment into encoded neural signals.  5. judgment  Evaluation of evidence  Making of decision2/15/2013 drjma
  4. 4. Process of Transduction  refers to changing physical energy into electrical signals (neural impulses) that can make their way to the brain.2/15/2013 drjma
  5. 5. Nature of Mind - is its relation to the physical brain and nervous system - Is somehow separate from physical existence - deriving from and reducible to physical phenomena - is identical with the brain or some activity of the brain2/15/2013 drjma
  6. 6. Whatever its relation to the physical body it isgenerally agreed that mind is that which enablesa being to:1. Subjective awareness and intentionality towards their environment,2. perceive and respond to stimuli with some kind of agency, and3. consciousness, including thinking and feeling.2/15/2013 drjma
  7. 7. Important philosophers of mindinclude :  Plato - Greek Philosopher, presented ideas thru dramatic dialogues  Descartes – French philosopher & mathematician. He concluded that everything was open to doubt except conscious experience.  Leibniz- German rationalist, he devised a method of calculus  Kant – German philosopher, he argued that reason is the means by which the phenomena of experience are translated to understanding.2/15/2013 drjma
  8. 8. influential theories about the nature ofthe human mind developed by:  Siegmund Freud = Neurologist & Psychoanalyst  Id, ego, super-ego are three parts of psychic apparatus  William James = Philosopher & Psychologists,  “the meaning of truth”  “The will to believe”  ?The sentiment of rationality in mind”2/15/2013 drjma
  9. 9. Attributes of Mind:  "higher" intellectual functions constitute mind, particularly reason and memory  various rational and emotional states cannot be so separated  it is a private sphere to which no one but the owner has access  can only interpret what we consciously or unconsciously communicate2/15/2013 drjma
  10. 10. Mental Faculties:  "higher" cognitive function and the analysis of thinking processes is a part of cognitive psychology  connected with our capacity to make and use tools to understand cause and effect  engage in problem solving, reasoning and making decisions  allows human beings to make sense of things in the world, and to represent and interpret them in ways that are significant, or which accord with their needs, attachments, goals, commitments, plans, ends, desires  involves the symbolic or semiotic mediation of ideas or data, as when we form concepts2/15/2013 drjma
  11. 11. Mental content  are those items that are thought of as being "in" the mind, and capable of being formed and manipulated by mental processes and faculties - Examples: - Thoughts – idea/mental picture - concepts – abstract idea/ general notion - memories – person’s power to remember things - Emotions – any particular feelings - percepts – something that is perceived - Intentions – the act or fact of intending2/15/2013 drjma
  12. 12. BRAIN & MIND  Brain, or encephalon (Greek for "in the head")  control center of the central nervous system  responsible for thought  located in the head,  protected by the skull and  close to the primary sensory apparatus of vision, hearing, equilibrioception, taste and olfaction  all vertebrates have a brain, most invertebrates have either a centralized brain or collections of individual ganglia2/15/2013 drjma
  13. 13. - Primitive animals such as sponges do not have a brain at all. - Brains can be extremely complex. - For example; the human brain contains more than 100 billion neurons, each linked to as many as 10,000 others2/15/2013 drjma
  14. 14. Part of the nervous systemSensory system2/15/2013 drjma
  15. 15. Relationship between the brain andthe mind:  physical brain matter and the mind is the impact physical alterations to the brain have on the mind,  such as with traumatic brain injury and psychoactive drug use  relationship between mental activity and brain activity  drugs influence cognition, and  neural correlates of consciousness.2/15/2013 drjma
  16. 16. Anatomy/Physiology A. Neuron- highly specialized for the processing and transmission of cellular signals 1. Basic component of the nervous sy. 2. Composed of cell body, axon & dendrites a. Cell body = center of metabolism b. Axon =long fibers > conduct impulses away from the cell body; usually 1 axon for each cell body c. Dendrites = short, unsheathed fibers> receive nerve impulses> transmit to cell body2/15/2013 drjma
  17. 17. 3 major philosophical schools ofthought of MIND:  Dualism holds that the mind exists independently of the brain  materialism holds that mental phenomena are identical to neuronal phenomena  idealism holds that only mental phenomena exist2/15/2013 drjma
  18. 18. Philosophy & Psychology of MIND:  the branch of philosophy & psychology that studies the nature of the mind, mental events, mental functions, mental properties, consciousness and their relationship to the physical body.2/15/2013 drjma
  19. 19. SCIENCE of mind:  Psychology is the scientific study of human behavior, mental functioning, and experience  Psychology involves the scientific study of mental processes  such as perception, cognition, emotion, personality, as well as environmental influences, such as social and cultural influences, and interpersonal relationships, in order to devise theories of human behaviour.2/15/2013 drjma
  20. 20.  Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals daily lives and the treatment of mental health problems.  Noology the study of thought. As both an academic and applied discipline,2/15/2013 drjma
  21. 21. Mental health• "A state of emotional and psychological well- being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life." According to the World Health Organization (WHO)2/15/2013 drjma
  22. 22. Mind/Body Perspectives:• Monism is the position that mind and body are not physiologically and ontologically distinct kinds of entities• According to Spinozas dual-aspect theory, mind and body are two aspects of an underlying reality which he variously described as "Nature" or "God".2/15/2013 drjma
  23. 23. “When we talk about understanding, surely it Takes place only when the mind listens Completely --- the mind being your Heart, your nerves, your ears == When you give your whole Attention to it.” -Jiddu Krishnamurti2/15/2013 drjma
