We all look forward to a good sleep. Conway MA, Pleydell-Pearce CW. In addition, as with the function of any memory system, the ability to recall prior experiences is the consequence of successful learning and allows those experiences to shape our interaction with the world in light of them. The activation of prior experience in a truly continuous manner would mean that we need to access all aspects of that prior experience. For example, individuals with direct military experience of war have direct, unambiguous, and sometimes apparently veridical dream incorporations of their experiences; civilians, on the other hand, have “indirect” or “symbolic” incorporations (78). J Cogn Neurosci (2003) 15:1–9. While sleep patterns change as we age, the amount of sleep we need generally does not * * Yes- A regular waking time in the morning strengthens the circadian function and can help with sleep onset at night. doi:10.1037/a0037817, 8. Trends Cogn Sci (2007) 11(10):442–50. Trends Cogn Sci (2001) 5(9):394–400. Getting up is hard to do, as your cold brain tries to warm up and notice what's going on. 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. Oddly, deep sleep is where sleepwalking and other funky sleep movements occur. Or the conscious act of daydreaming: a part-focused activity perhaps with a pleasant goal but one that requires fantasy, mind-wandering and a loss of engagement with reality. This awareness of the origin of events as being either internal, such as a thought or a dream, or external in that it is truly perceived, is known as reality monitoring (37). This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness … Malinowski JE, Horton CL. Memory in the Real World. (22, 23)]. Rather, discontinuity in sleep, and likely in wake also though perhaps to a lesser extent, may reflect offline processing that maintains the organization and consolidation of experiences within a neurocognitive system that is constantly being updated. What is Consciousness? Int J Dream Res (2012) 4(Suppl 1):S45. A person with sleep apnea stops breathing while they sleep due to obstruction to their airway. During sleep, as evidenced from dream reports from across the night, experiences from our waking lives are particularly discontinuous as specific constituent features of autobiographical experiences are selected for processing. The content of this field is kept private and will not be shown publicly. A handful of dream studies have been able to map the activation of a specific memory source over time, although unfortunately these studies are varied in their methodological approach. Dissociation can be exacerbated by sleep loss (45) and sleep disturbances are symptomatic (or perhaps even causal) of virtually all mental disorders as listed in the DSM-5 (43). J Behav Ther Exp Psychiatry (2015) 47:9–17. Very rarely do we recall episodes in this way. Behav Brain Sci (2013) 36:589–607. For thousands of years, the study of human consciousness was largely the work of philosophers. Llewellyn (65) illustrates this in detail with her “quicksand dream,” showcasing how various different elements of waking life had been recombined and synthesized into a single, composite dream event. As such, we can present two arguments: (i) consciousness is varied across both sleep and wake, yet (ii) in both states continuity of memory may not prevail. Perogamvros L, Dang-Vu TT, Desseilles M, Schwartz S. Sleep and dreaming are for important matters. doi:10.1080/10673220802432517. Int J Dream Res (2011) 4(2):86–92. The role of sleep in changing our minds: a psychologist’s discussion of papers on memory reactivation and consolidation in sleep. Kozmová M, Wolman RN. As Hartmann (21) suggested, but did not test empirically, REM sleep cognition may be hyperassociative, in that the links from one activated thought to another are more tenuous than in waking. Malinowski JE, Horton CL. For example, recalling a dream (continuity of dreaming memories to wake) may involve accessing a number of features of the original experience, but with some added appraisal of the experience and with some features being omitted from memory. Kahan and LaBerge (35) suggest that differences between waking and dreaming cognition may be quantitative; there being more of certain cognitions in waking than dreaming and vice versa, but not qualitative, since there were incidences of the different types of cognitions sampled from both states. Continuity, therefore, would be high if AMs were activated and recalled accurately and in full. As stated earlier, continuity may reflect maladaptive processing. While there seems to be change in the manifestation and perhaps function of consciousness both across sleep and wake, and within each of those states, there also exists continuity. Fluctuating states of consciousness confuse the heck out of people but are very common. We also alter our consciousness through the use of various psychoactive drugs. Exploring the role of need for cognition, field independence and locus of control on the incidence of lucid dreams during a 12 week induction study. Cell Mol Life Sci (2009) 66:2285–97. doi:10.1073/pnas.012689199, 69. Indeed, in order to explore discontinuities across sleep and wake, Kunzendorf et al. As such, we cannot assume that discontinuity functions to make revelations conscious. A new approach to dream bizarreness: graphing continuity and discontinuity of visual attention in narrative reports. Conscious Cogn (1997) 6(6):132–47. Diagnostic and Statistical Manual of Mental Disorders. Dream recall and confabulation. In their study, Kozmová and Wolman (40) identified thought units as featuring cognitive or metacognitive processing, such as being analytical or operational, and in doing so illustrated the complexity of cognitions available in dreaming, concluding that the content of the dream (be it bizarre or not) does not preclude the application of rational thought, much like one would in waking life, and in fact the thought processes applied to a dream situation have much in common with those applied to a situation experienced in waking life. 63. Hobson JA, Pace-Schott EF, Stickgold R. Dreaming and the brain: toward a cognitive neuroscience of conscious states. Dreaming (2005) 15(3):155–69. Similarly dreaming of an upcoming social event (from waking life) may seem largely continuous in the manner of reflecting concerns, characters involved and the general setting, but could be discontinuous in that the actual future event could never happen. What Might be the Function of Continuity? Front Psychol (2015) 6:874. doi:10.3389/fpsyg.2015.00874. Stickgold and Walker (42) presented a “triage” model of sleep-dependent memory consolidation, whereby salient aspects of an experience are tagged as requiring processing during sleep. 1. Discontinuity could present as disjointed cognition, with absences or lapses in attention (i.e., consciousness being interrupted). doi:10.1093/sleep/6.3.265.
