Cartwright RD. Psychol Rev (2000) 107(2):261–88. Search. REM sleep, prefrontal theta, and the consolidation of human emotional memory. If we proceed with our definition of consciousness as a holistic experience of the present, brief past, long-term past (via memory retrieval) and the future (goal directed), we may assume that the ability to recall prior experiences, i.e., for continuity to function, would allow focus to be maintained in reaching future goals. Imagination Cogn Pers (2014) 34(2):163–77. Nevertheless the relationship between REM sleep and novel ideas has been shown in a number of empirical investigations exploring not only creativity but also problem solving and insight. Also the memory fragments that were rebound with another memory (source) during dreaming should lead to enhanced recallability of both the original source of the memory fragment as well as the memory source that appeared in the dream, relative to memories and fragments that had not been dreamed about, due to all these aspects having been activated during sleep. These predictions present exciting opportunities for the collaboration of dream and sleep scientists with memory consolidation scholars, to explore the nature of sleeping mentation as a reflection of the cognitive processes of memory reorganization over time. Malinowski JE, Horton CL. For instance, some existing work has identified benefits of a labile sleep–wake pattern in terms of the number of cycles through sleep stages upon knowledge awareness tasks (84, 85) and recent work has identified that lucid dreaming training benefits performance in field independence tasks (86). Trends Cogn Sci (2001) 5(9):394–400. 31. But strictly speaking during sleep your are not consciously aware of your actual environment. doi:10.1006/ccog.1994.1005, 50. Disturbed dreaming, posttraumatic stress disorder, and affect distress: a review and neurocognitive model. doi:10.1016/j.smrv.2014.06.004, 16. doi:10.1037/0096-3422.214.171.1249. Kirov R, Kolev V, Verleger R, Yordanova J. Labile sleep promotes awareness of abstract knowledge in a serial reaction time task. It also assumes that any as yet explained variance may be problematic, or simply, “error.” Indeed, discontinuities have been somewhat dismissed as being either a product of activation-synthesis [for instance, see Ref. This model of sleep-dependent memory consolidation accounts for the discontinuity within REM sleep mentation, and perhaps in elements of non-REM sleep reports and in aspects of waking also, as the fragmentary activation of specific memories being coupled with other memory fragments, giving rise to a new image, illustrates discontinuity clearly. 11. doi:10.1093/brain/120.7.1173, 33. This should be mapped on to changes in the continuity, or order, of the conscious manifestation of that experience. While sleep patterns change as we age, the ... At our deepest level of sleep our brain waves actually resemble our _____ Do we sleep more if we are physically active? Schreuder BJN, Igreja V, van Dijk D, Kleijn W. Intrusive re-experiencing of chronic strife or war. As such according to this model, discontinuity is the norm during REM sleep and is taken to reflect the lack of order and purpose of the epiphenomena of dreams. Our states of consciousness change as we move from wakefulness to sleep. This is essentially a state somewhere between stage 1 sleep and wakefulness, and can lapse in and out of the two for many minutes before people stop hitting the snooze button and actually rouse themselves out of bed. Front Psychol (2015) 6:324. doi:10.3389/fpsyg.2015.00324, 65. This raises questions concerning the extent to which continuity and discontinuity may be “normal” in terms of being psychologically healthy. Conscious Cogn (2003) 12:298–308. References. Taken together, there is much evidence for comparable cognitive processing across sleep and wake. 4. What are three view on why we sleep? This causes their body to reflexively awaken in order to breathe again. doi:10.1046/j.1365-2869.2003.00344.x, 13. Future work should aim to characterize dream–wake continuity in specific ways, noting trends for specific memory features to be either largely continuous or discontinuous.3 This may help to alleviate concerns with discontinuity as being merely unexplained variance in models of continuity that aim to predict dreaming behavior.
