To extend the hypothesis that bizarre discontinuities in dreams result from the interaction of chaotic, "bottom-up" brainstem activation with "top-down" cortical synthesis, we have performed a detailed analysis of dream discontinuities using a new methodology that allows for objective characterization of this formal dream feature. Transformations of characters and objects in dream reports were found to follow definite associational rules. While there were 11 examples of character–character transformation and 7 of inanimate object–inanimate object transformation, transformations of characters into inanimate objects and vice versa were never observed. Judges′ scores on a transformation-matching task further showed that the nature of the transformed character or object is highly constrained by the features of the initial character or object . We conclude that despite the threat to dream coherence posed by bizarre discontinuities, significant coherence is maintained by associational constraints, especially in the case of object and character transformations

We have conducted a home-based study of children′s dream reports in which parents used open-ended interviewing styles to collect 88 dream reports from their 4- to 10-year-old children in the comfortable and supportive environment of their own homes. Particular attention was paid to formal properties including characters , settings, self-representation, and bizarreness. In contrast to previous studies, our data indicate that young children are able to give long, detailed reports of their dreams that share many formal characteristics with adult dream reports. Because this wide range of dream mentation is only revealed to trusted confidants in a familiar and comfortable environment, an important implication is that the sleep laboratory may not be the best source of naturalistic dream data

We have investigated the emotional profile of dreams and the relationship between dream emotion and cognition using a form that specifically asked subjects to identify emotions within their dreams. Two hundred dream reports were collected from 20 subjects, each of whom produced 10 reports. Compared to previous studies, our method yielded a 10-fold increase in the amount of emotion reported. Anxiety/fear was reported most frequently, followed, in order, by joy/elation, anger, sadness, shame/guilt, and, least frequently, affection/eroticism. Unexpectedly, there was no significant difference in the profiles of emotion reported by men and women. When the reports were scored for bizarreness, a significant correlation was found between the occurrence of bizarreness and major shifts in emotion. These results support the conclusion that dreaming is a mental state whose general emotional features are widely shared across individuals and strongly linked to cognitive features within individual dreams

Definitions of dreaming are not required to map formal features of mental activity onto brain measures. While dreaming occurs during all stages of sleep, intense dreaming is largely confined to REM. Forebrain structures and many neurotransmitters can contribute to sleep and dreaming without negating brainstem and aminergic-cholinergic control mechanisms. Reductionism is essential to science and AIM has considerable heuristic value. Recent findings support sleep's role in learning and memory. Emerging technologies may address long-standing issues in sleep and dream research.

Thinking is known to be state dependent but a systematic study of how thinking in dreams differs from thinking while awake has not been done. The study consisted of analyzing the dream reports of 26 subjects who, in addition to providing dream reports also provided answers to questions about their thinking within the dream. Our hypothesis was that thinking in dreams is not monolithic but has two distinct components, one that is similar to wake-state cognition, and another that is fundamentally different. We found that cognition within a dream scenario was similar to that of wake-state cognition, but that thinking about the scenario itself was deficient and very different than wake-state thinking

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep

Consciousness can be studied only if subjective experience is documented and quantified, yet first-person accounts of the effects of brain injury on conscious experience are as rare as they are potentially useful. This report documents the alterations in waking, sleeping, and dreaming caused by a lateral medullary infarct. Total insomnia and the initial suppression of dreaming was followed by the gradual recovery of both functions. A visual hallucinosis during waking that was associated with the initial period of sleep and dream suppression is described in detail. Since the changes in sleep and their recovery are comparable to results of animal experiments, it can be concluded that damage to the medullary brain stem causes extreme but short-lived alterations in conscious state and that substantial recovery occurs even though the damage to the brain stem endures.

This study investigated the relationship between dream emotion and dream character identification. Thirty-five subjects provided 320 dream reports and answers to questions on characters that appeared in their dreams. We found that emotions are almost always evoked by our dream characters and that they are often used as a basis for identifying them. We found that affection and joy were commonly associated with known characters and were used to identify them even when these emotional attributes were inconsistent with those of the waking state. These findings are consistent with the finding that the dorsolateral prefrontal cortex, associated with short-term memory, is less active in the dreaming compared to the wake brain, while the paleocortical and subcortical limbic areas are more active. The findings are also consistent with the suggestion that these limbic areas have minimal input from the dorsolateral prefrontal cortex in the dreaming brain.

First published in 1931, this _Routledge Revivals_ title reissues J.A Hobson’s analysis of financial distribution in the early years of Twentieth Century Britain. The book focuses on the moral questions that he considered to be important in regard to the economic reforms that were necessary to secure the utilisation of modern productivity for the welfare of mankind. In this work, Hobson considers the wasteful working of the economic system, with its over-production, under-consumption and unemployment and states that these errors are due to the unfair way in which income is apportioned among the nations, classes and individuals that produce it. _Poverty in Plenty_ argues for a conscious economic government inspired by a sense of justice and humanity. It makes suggestions towards the establishment of such a government and presents business prosperity as a problem of morals.

First published in 1913, this _Routledge Revivals_ title reissues J. A. Hobson’s seminal analysis of the causal link between the rise in gold prices and the increase in wages and consumer buying power in the early years of the Twentieth Century. Contrary to the assertions of some notable contemporary economists and businessmen, Hobson contended that the relationship between gold prices and wages (and the resulting social unrest across much of Europe) was in fact much more complex than it initially appeared and that there were significantly more important factors in the rise of contemporary wealth, such as the rapid enlargement of state enterprise and joint stock companies; a wide extension of banking and general financial apparatus; and the opening of profitable fields of investment for the development of underdeveloped countries, which helped raise the rate of interest and profits.

How can we investigate the relation between language and the human capacity for intersubjective engagement? Here we combine insights from linguistics and psychology to study the language of children with autism. We begin by reviewing why it might be worthwhile to study autism from the perspective of dialogic resonance, defined as the catalytic activation of affinities across utterances. Then we report on a controlled study of conversations involving individual children with autism and an interested adult interviewer. According to reliable ratings of the transcribed conversations, each considered as a whole, the speech of participants with autism was characterized by atypical forms of dialogic resonance. On the other hand, the children with autism were similar to control participants insofar as their conversations manifested “typically developed frame grabs” in which dialogic resonance was accompanied by a coherent expansion. These findings were compatible with those that emerged from utterance-by-utterance analyses of the same conversations reported elsewhere (Hobson et al. 2012). To complement the quantitative findings, we present illustrative excerpts of language use. We consider how dialogic resonance relates to structural priming, and consider implications for understanding the relations among intersubjectivity, language, and autism.
