Definition and hypothesis in Plato's meno (II)

The application of semantical concepts such as synonymy and interpretation to actual situations of usage gives rise to perplexing problems. One of the few attempts to tackle these problems has been carried out by Arne Naess. Further advances along this line may become possible after a clarification of the basic concepts employed. The discussion centers around empirical synonymy and certain other notions built on this concept by Naess. Possible ways of making the system coherent are indicated.     

Definition and hypothesis in Plato's meno (III)

With the publication of The Social Frameworks of Knowledge? the English speaking world has at last been given a serious opportunity to approach the complex sociological thought of Georges Gurvitch. However, as the author himself admits in the Preface, this book appears ‘abstract and schematic particularly to the uninitiated’.1 The aim of this paper will be to try to relate this translated work to the main body of Gurvitch's writing and particularly to his stance in the sociology of knowledge. First I will examine the intellectual origins of his sociology of knowledge and his attitude to his predecessors in the field. Secondly I will compare his approach to the sociology of knowledge to that of P. L. Berger and T. Luckmann.     

The influence of symbolic literacy on memory: testing Plato's hypothesis.

The present study examined the influence of the production of external symbols on memory strategies. Plato hypothesized that dependency on writing as an external memory store would be deterimental to memory. Three experiments were conducted to explore this hypothesis. Participants played Concentration, a memory game where players must find matching pairs of cards placed face down in an array. Participants were allowed to make notes to aid their performance under some experimental conditions, while under other conditions they could not. In Experiments 1 and 2, the unexpected removal of participants' notes revealed that the performance benefit was due to notes acting as a form of external memory storage, rather than as an aid to encoding information in memory. Experiment 3 qualified these findings by demonstrating that the identity of each card was retained in memory, while the location of each card tended to be stored in the participants' external notations. These data suggest a modified interpretation of Plato's hypothesis in that symbolic literacy may change how we remember information. Rather than storing all information in memory, we only have to retain the information necessary to use the much larger storage capacity of the external system. Thus, the introduction of external symbols allows for a change in how memory is adaptively distributed.     

Definition and hypothesis in Plato's Meno 1 (I)

There is no amount or quality of evidence such that if that amount or quality is reached, then truth is reached. If, therefore, a proposition must be true in order to constitute knowledge, knowledge is never reached. If certain standards of evidence are satisfied I have the right to say ’I know’, and the right does not depend on how one answers the question whether it is right what I say.     

Testing the implicit processing hypothesis of precognitive dream experience

Seemingly precognitive (prophetic) dreams may be a result of one’s unconscious processing of environmental cues and having an implicit inference based on these cues manifest itself in one’s dreams. We present two studies exploring this implicit processing hypothesis of precognitive dream experience. Study 1 investigated the relationship between implicit learning, transliminality, and precognitive dream belief and experience. Participants completed the Serial Reaction Time task and several questionnaires. We predicted a positive relationship between the variables. With the exception of relationships between transliminality and precognitive dream belief and experience, this prediction was not supported. Study 2 tested the hypothesis that differences in the ability to notice subtle cues explicitly might account for precognitive dream beliefs and experiences. Participants completed a modified version of the flicker paradigm. We predicted a negative relationship between the ability to explicitly detect changes and precognitive dream variables. This relationship was not found. There was also no relationship between precognitive dream belief and experience and implicit change detection.     

A significant "dream within a dream"

This brief clinical note is an attempt to clarify Freud's remarks regarding the significance of real occurrences of the "dream within a dream". There is affirmation of the reality of an actual event in the manifest dream (the "tickling" in adolescence). Certain representations regarding real events are alluded to in the manifest dream and are confirmed by the latent dream thoughts (the underlying homosexual theme involving the patient's mother and herself). Within the ongoing transference neurosis, a new understanding led this patient to experience intense sexual affects which were recalled for the first time during the course of an analytic session. The analyst's attention to this "dream within a dream" led to a facilitating active interpretation of the repressed sexual feelings. At the same time it was possible to observe a developmental arrest which had interfered with the consolidation of the patient's adolescent maturation begin to be undone by interpretation. The process of disengaging the patient from her unconscious bond with her mother (the undoing of the negative oedipal involvement) had been set in motion. The "dream within a dream" seems to represent a special defensive effort of the dream work to encapsulate the memory of one or more related actual events and the intense affects associated with them--affects whose pressure for discharge threaten to arouse the sleeper. The form the dream assumes is related to its hidden sexual origins and engages the active participation of both patient and analyst.     

Dormio: A targeted dream incubation device

Information processing during sleep is active, ongoing and accessible to engineering. Protocols such as targeted memory reactivation use sensory stimuli during sleep to reactivate memories and demonstrate subsequent, specific enhancement of their consolidation. These protocols rely on physiological, as opposed to phenomenological, evidence of their reactivation. While dream content can predict post-sleep memory enhancement, dreaming itself remains a black box. Here, we present a novel protocol using a new wearable electronic device, Dormio, to automatically generate serial auditory dream incubations at sleep onset, wherein targeted information is repeatedly presented during the hypnagogic period, enabling direct incorporation of this information into dream content, a process we call targeted dream incubation (TDI). Along with validation data, we discuss how Dormio and TDI protocols can serve as tools for controlled experimentation on dream content, shedding light on the role of dreams in the overnight transformation of experiences into memories.     

Digital dream analysis: A revised method

This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams. A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four “classic” sets of dreams: The male and female “Norm” dreams of Hall and Van de Castle (1966), the “Engine Man” dreams discussed by Hobson (1988), and the “Barb Sanders Baseline 250” dreams examined by Domhoff (2003). A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis.     

A pilot study for the analysis of dream reports using Maslow's need categories: an extension to the emotional selection hypothesis

The emotional selection hypothesis describes a cyclical process that uses dreams to modify and test select mental schemas. An extension is proposed that further characterizes these schemas as facilitators of human need satisfaction. A pilot study was conducted in which this hypothesis was tested by assigning 100 dream reports (10 randomly selected from 10 dream logs at an online web site) to one or more categories within Maslow's hierarchy of needs. A "match" was declared when at least two of three judges agreed both for category and for whether the identified need was satisfied or thwarted in the dream narrative. The interjudge reliability of the judged needs was good (92% of the reports contained at least one match). The number of needs judged as thwarted did not differ significantly from the number judged as satisfied (48 vs. 52%, respectively). The six "higher" needs (belongingness, esteem, cognitive, aesthetic, self-actualization, and transcendence) were scored significantly more frequently (81%) than were the two lowest or "basic" needs (physiological and safety, 19%). Basic needs were also more likely to be judged as thwarted, while higher needs were more likely to be judged as satisfied. These findings are discussed in the context of Maslow's hierarchy of needs as a framework for investigating theories of dream function, including the emotional selection hypothesis and other contemporary dream theories.     

Emil Kraepelin's dream speech: A psychoanalytic interpretation

Freud's contemporary fellow psychiatrist Emil Kraepelin collected over the course of several decades some 700 specimens of speech in dreams, mostly his own, along with various concomitant data. These generally exhibit far more obvious primary-process influence than do the dream speech specimens found in Freud's corpus; but Kraepelin eschewed any depth-psychology interpretation. In this paper the authors first explore the respective orientations of Freud and Kraepelin to mind and brain, and normal and pathological phenomena, particularly as these relate to speech and dreaming. They then proceed, with the help of biographical sources, to analyze a selection of Kraepelin's deviant dream speech in the manner that was pioneered by Freud, most notably in his 'Autodidasker' dream. They find that Kraepelin's particular concern with the preservation of his rather uncommon family name-and with the preservation of his medical nomenclature, which lent prestige to that name-appears to provide a key link in a chain of associations for elucidating his dream speech specimens. They further suggest, more generally, that one's proper name, as a minimal characteristic of the ego during sleep, may prove to be a key in interpreting the dream speech of others as well.     

A parapraxis in a dream

When a parapraxis is put on display in a dream, one can only wonder what service the willful mistake is rendering to resourceful dream work. Freud taught us that anything that appears in the manifest content of a dream may well be a disguise or a distortion of a subject that originally made an anxiety-provoking, and hence short-lived, first appearance in latent dream thoughts. Dreams in dreams and jokes in dreams have been examined from this perspective (Mahon 2002a, 2002b), and this paper focuses on the appearance and meaning of a parapraxis in a dream, with the argument that seemingly casual "mistakes" are highlighted in the manifest display to cover up some latent, much more deliberate subject matter.     

A poem and a dream

Recently, a journalist in analysis had a dream that stimulated the writing of a poem, the two psychic products occurring no more than a few hours apart. Since the analysand had copious free associations to both products, believing both to be culled from the same unconscious raw material, an interesting study of an act of aesthetic creation almost in statu nascendi became possible. A concept called poem work is entertained in this paper and is compared and contrasted with the classical psychoanalytic concept of dream work, allowing some unanswerable questions to be posed and discussed in regard to the formal constitutive elements of poetry.
