Presentation Transcript

  1. Explanations of dreaming • Psychological theories • Ego defence (Freud) • Problem solving (Webb & Cartwright) • Physiological theories • Reverse learning (Crick & Mitchison) • Activation synthesis (Hobson & McCarley) psychlotron.org.uk

  2. Explanations of dreaming • Psychological & physiological theories differ in terms of: • Emphasis on subjective vs. objective features of dreaming • Assumptions about meaningfulness of dream experiences psychlotron.org.uk

  3. Ego defence • Weakening of ego • Unconscious ideas impinge on conscious • Dream work by the ego • Manifest & latent dream content psychlotron.org.uk

  4. Ego defence - symbols psychlotron.org.uk

  5. Problem solving • Agrees with idea that subjective dream content is significant • Disagrees with idea that meaning is hidden behind symbolism • Suggest direct relationship between dream content & problems from waking life • Dreaming allows mind to form new associations to help solve problems psychlotron.org.uk

  6. Psychological theories • Main predictions: • Brain systems involved with emotion will be active; those involved with rationality will not • Dreams will reflect current problems • Dreams will provide solutions • Dreams will be remembered psychlotron.org.uk

  7. Physiological Theories • Activation synthesis • Dreaming is a by-product of brain activity during REM sleep, which is carried out for brain restoration • Parts of the brain associated with memory & emotion become activated • The frontal cortex ‘synthesizes’ a story to make sense of it psychlotron.org.uk

  8. Physiological theories • Reverse learning • During waking, brain takes in lots of info, not all of which is important • During dreaming, such ‘parasitic’ info is cleared out, allowing more efficient access to important info • ‘Storage space’ is freed up, like defragging a hard-drive • Dreaming is a meaningless by-product of this process psychlotron.org.uk

  9. Physiological theories • Main predictions: • Dreams will be meaningless & bizarre • Dreams will be quickly forgotten • Mammals that do not have REM sleep will have large brains (or large cortexes) psychlotron.org.uk
