The imaginative use of religious symbols in subjective experiences of anorexia nervosa.

Clinicians working with contemporary women with anorexia nervosa have commented on the ascetic component in anorexia, meaning their self-denial, heightened morality, opposition between body and spirit, asexuality, and denial of bodily death (Mogul, 1980; Palazzoli, 1978; Rampling, 1985; Sabom, 1985; Turner, 1984). While these clinicians have commented on the asceticism in contemporary anorexia nervosa, they have little to say about the role of culture in subjective experiences of this asceticism. As we have seen, Jane and Margaret used notions of asceticism about food and the body that are a part of their religious beliefs to create a personal meaning system through which they expressed their self-starvation. These cases, while supporting clinical studies that point to an ascetic component in modern anorexia, go further to suggest that in some cases, this asceticism may be encoded in religion. Religious anorectics like Jane and Margaret challenge models of anorexia nervosa that understand the condition exclusively in terms of cultural foci on "dieting" and secular ideals of beauty and bodily thinness for women (Bemporad, Hoffman, & Herzog, 1989; Chernin, 1985; Garner et al., 1980; Orbach, 1986; Rost, Newhaus, & Florian, 1982). They also suggest a continuing persistence into the twentieth century of an association between religiosity and self-starvation noted by historians during the early Christian, medieval, and late-Victorian periods in the West (Bell, 1985; Brown, 1988; Brumberg, 1985, 1988; Bynum, 1987). The above discussion points to the new directions in psychological anthropology which challenge a strict and opposing dichotomy between the conscious and unconscious, between culture (seen as "public") and the individual mind (seen as "private" and idiosyncratic). Obeyesekere's concept of "the work of culture," (Obeyesekere, 1990) and Stephen's concept of the "autonomous imagination" are especially useful in understanding how persons like Jane and Margaret use in imaginative ways cultural symbols, such as notions of asceticism about food and the body that are a part of religion, to give meaning to their personal concerns with growth, separation, and sexuality. We saw how Jane and Margaret transform cultural symbols and language to express their starvation and deep anxieties. These cases lend support to views that culture and religion, as symbolic systems, have underpinnings in deep motivation (Obeyesekere, 1981, 1990; Spiro, 1965, 1987). They also suggest that the relations between culture and the individual mind (and between culture and "illness," between "normal" and "abnormal") must be viewed as a moving continuum, with culture constantly worked and reworked by the individual imagination in innovative and creative ways.

[Correlation of scope and content in treatment of dyssocial children and adolescents. A psychoanalytic study of disordered symbolization processes].

The article discusses the significance of a holding therapeutic environment for the processes of symbol development. Using epistomological psychoanalytic concepts it demonstrates, through a series of examples, how semiotic progression can be facilitated or how, through insufficient handling of frame guiding therapeutic semiotic regression--in the sense of a "reversal of alpha function"--can be triggered, with a resultant increase in symptomatic behavior. The distinction is drawn between three different levels of mental functioning: At the deepest level, behavior is controlled according to somatic, autoregulative and homoeostatic principles. The second level is concerned with mental functioning, such as determines behavior of individuals within a group and which is influenced by symbol systems and affective automatisms, while obeying a type of "symmetrisation-mechanism." Only at the third level, we are concerned with psychic spaces and the thinking subject, who is capable of symbolic interaction with both the internal and external world.

[Aspects of group therapy with sexually abused children--symbolic processing and construction of the initial phase].

This study deals with aspects of group therapy with traumatized children. Various examples from a children's therapy group with sexually abused girls at the age of nursery and primary school enlighten the theoretical explanations. With a reflexion about traumatization by sexual abuse as a starting point a catalogue of therapeutical ends is set up including a methodic realization in exemplary form. A central point is marked by reflexions on the featuring of the initial phase: according to the high level of fear in the children and their minimal abilities to set up limits, there has to be a procedure of absolutely clear structuring; considerations on means establishing security are being focussed. Moreover, this study describes the use of forms of coping by symbols. With the help of theoretical considerations on the role of symbolic function and the games children play the use of the former is explained. Concrete proceeding and the efficacy of coping by symbols are made obvious throughout a treasure of examples. The central motive of this study is to give concrete impulses for practical work with traumatized children and not to discover new continents through scientific research.

Nonlinear measures of heart period variability: decreased measures of symbolic dynamics in patients with panic disorder.

Time series of heart period are not linear and recent studies illustrated the importance of using nonlinear methods to quantify the complexity of these time series. We compared different techniques to quantify the nonlinear complexity of these time series in patients with panic disorder and normal controls and correlated these measures with spectral powers in different bands of interest. Twenty-four hour ECG was recorded in 23 normal controls and 29 patients with panic disorder by using Holter records. Time series of heart period were analyzed by using approximate entropies, slopes of 1/f scaling, two algorithms to calculate fractal dimension, and word sequences using symbolic dynamics. Measures using symbolic dynamics, especially word count (WC-100), showed highly significant differences between the two groups similar to some of the frequency domain (spectral) measures, while the other techniques were relatively ineffective to distinguish between the two groups. Different nonlinear techniques may relate to different aspects of nonlinear complexity of the time series. These nonlinear techniques were also not uniform in showing the differences between awake and sleep periods. Some correlate with the measures of respiratory sinus arrhythmia and some measures obtained from symbolic dynamics may reflect not only the nonlinear complexity of the time series but also the total variability in the 24 hr HP time series, especially power in the ultra-low frequency band (< 0.0033 Hz). However, word count (WC-100) had only weak correlations with other measures and discriminated best between the two groups and showed that this nonlinear measure was of additional value to the linear measures in classifying the two groups.

Inconsistencies in pedigree symbols in human genetics publications: a need for standardization.

To determine consistency in usage of pedigree symbols by genetics professionals, we reviewed pedigrees printed in 10 human genetic and medical journals and 24 medical genetics textbooks. We found no consistent symbolization for common situations such as pregnancy, spontaneous abortion, death, or test results. Inconsistency in pedigree design can create difficulties in the interpretation of family studies and detract from the pedigree's basic strength of simple and accurate communication of medical information. We recommend the development of standard pedigree symbols, and their incorporation into genetic publications, professional genetics training programs, pedigree software programs, and genetic board examinations.

Aboriginal spirituality: symbolic healing in Canadian prisons.

Symbolic healing is a complex phenomenon that is still relatively poorly understood. This paper documents a process of symbolic healing which is occurring in Canadian penitentiaries, and which involves Aboriginal offenders in cultural awareness and educational programs. The situation is compounded, however, by the existence of offenders from diverse Aboriginal cultural backgrounds with differing degrees of orientation to Aboriginal and Euro-Canadian cultures. Participants must first receive the necessary education to allow them to identify with the healing symbols so that healing may ensue, and both the healers and the patients must engage in a process of redefining their cultures in search of a common cultural base.

Numeric and symbolic knowledge representation of cerebral cortex anatomy: methods and preliminary results.

The human cerebral cortex anatomy describes the brain organization at the scale of gyri and sulci. It is used as landmarks for neurosurgery as well as localization support for functional data analysis or inter-subject data comparison. Existing models of the cortex anatomy either rely on image labeling but fail to represent variability and structural properties or rely on a conceptual model but miss the inner 3D nature and relations of anatomical structures. This study was therefore conducted to propose a model of sulco-gyral anatomy for the healthy human brain. We hypothesized that both numeric knowledge (i.e., image-based) and symbolic knowledge (i.e., concept-based) have to be represented and coordinated. In addition, the representation of this knowledge should be application-independent in order to be usable in various contexts. Therefore, we devised a symbolic model describing specialization, composition and spatial organization of cortical anatomical structures. We also collected numeric knowledge such as 3D models of shape and shape variation about cortical anatomical structures. For each numeric piece of knowledge, a companion file describes the concept it refers to and the nature of the relationship. Demonstration software performs a mapping between the numeric and the symbolic aspects for browsing the knowledge base.

Effects of spatial and symbolic precues on localization performance.

One of the fundamental properties of spatial vision is the ability to localize objects in space. According to a recent proposal, accurate localization performance involves the operation of two systems: the attention system and the eye movement system. Upon stimulus presentation, attention is shifted to the target area: this provides coarse location information. Subsequently, a saccadic eye movement is executed: this provides fine location information. In this study we tested predictions derived from this model concerning the effects of precue information on localization performance. In a series of five experiments we manipulated duration of precue (71, 400, and 1,000 ms) and type of precue (spatial versus symbolic). Results showed that very short duration (i.e., 71 ms) spatial precues improved localization performance whereas very short duration symbolic precues did not. In contrast, the 1,000 ms duration precue condition showed similar amounts of precuing benefit for the spatial and symbolic precues. This pattern of differential precuing effects corroborated the two-process model of localization performance.

[Between symbol and symptom: pain and its meanings in classical antiquity].

According to semiotics, which may be defined as the doctrine of the essential nature and fundamental varieties of signs, objects, and interpretants, pain is considered to be a sign (significant) with very different meanings (significance) either as a naturalistic symptom (of disease) or as a symbol used in a metaphorical context. When following this methodological perspective it is possible to interpret medical as well as poetic writings on equal terms. In Graeco-Roman medical texts pain was mostly understood as a result and an indicator of disease, but nonetheless as a symptom which seemed to be actively produced by the affected body. Especially in the Corpus Hippocraticum dating from the 5th and 4th century B. C. this materialistic and at the same time psychosomatic attitude can be noticed. Aristotle (4th century B. C.), Celsus (1st century A. D.), and the famous experimental physiologist Galen (2nd century A. D.) agreed that pain was a sign of evil which should be fought without exception. It was Galen who added the disturbance of function (functio laesa) as the fifth cardinal sign of inflammation to the four well-known cardinal signs of Celsus (rubor, calor, tumor, dolor). He also coined the term [see text] to characterize an attack of migraine. In algotherapy, Galen used a complex pharmacological system which was based upon the four cardinal qualities of humoral pathology. On the other hand, pain was designed as a multi-dimensional symbol by the famous Graeco-Roman epic poets. In Homer's Odyssey (8th century B. C.), pain appears transformed into the shape of a scar which is visible and palpable on the hero's leg like an identification tag, whereas in Virgil's Aeneids (1st century B. C.) pain symbolizes weakness and defencelessness which can only be alleviated by the goddess Venus.

An interactive aid for expressive communication with pictographic symbols.

An individual who is unable to acquire skills in natural language communication may frequently find a pictographic symbolic language to be an appropriate alternative means of expression. This paper discusses some underlying features of the communication process and describes a computer-based augmentative aid for communication with pictographic linguistic units, which provides flexibility for user-definition of symbols, inter-symbol mapping and multi-mode expression. The system is consequently a potentially very powerful tool for the development and utilisation of communication processes among groups of users who do not necessarily share access to a common linguistic knowledge base.

Symbol-string sensitivity and children's reading.

In this study of primary school children, a novel 'symbol-string' task is used to assess sensitivity to the position of briefly presented non-alphabetic but letter-like symbols. The results demonstrate that sensitivity in the symbol-string task explains a unique proportion of the variability in children's contextual reading accuracy. Moreover, developmental dyslexic readers show reduced sensitivity in this task, compared to chronological age controls. The results suggest that limitations set by visuo-spatial processes and/or attentional iconic memory resources may constrain children's reading accuracy.

A common N400 EEG component reflecting contextual integration irrespective of symbolic form.

OBJECTIVE: Electroencephalographic (EEG) waves modulated by context have been identified about 400 ms after presentation of a new semantic stimulus, such as a word or a number, within a prior context. However, it is not known if any component of these waves arises from a common brain system activated by different symbolic forms. METHODS: Multichannel EEG recordings were performed in 10 healthy subjects during the presentation of lexical and numerical series with congruent and incongruent endings. EEG was analysed using a combination of independent component and cluster analysis. RESULTS: Contextual integration of semantic stimuli elicited a negative independent component at around 400 ms that shared the same pattern of spatio-temporal covariation across numerical series and sentences within single subjects. This independent component was bigger following incongruent endings. CONCLUSIONS: These data provide evidence that one element of the activity contributing to the N400 is common to different symbolic forms. SIGNIFICANCE: One component of the brain systems evaluating the semantic inter-relationship of new stimuli with prior context may be common to different symbolic forms.

Finding needles in haystacks: symbolic resonance analysis of event-related potentials unveils different processing demands.

Previous ERP studies have found an N400-P600 pattern in sentences in which the number of arguments does not match the number of arguments that the verb can take. In the present study, we elaborate on this question by investigating whether the case of the mismatching object argument in German (accusative/direct object versus dative/indirect object) affects processing differently. In general, both types of mismatches elicited a biphasic N400-P600 response in the ERP. However, traditional voltage average analysis was unable to reveal differences between the two mismatching conditions, that is, between a mismatching accusative versus dative. Therefore, we employed a recently developed method on ERP data analysis, the symbolic resonance analysis (SRA), where EEG epochs are symbolically encoded in sequences of three symbols depending on a given parameter, the encoding threshold. We found a larger proportion of threshold crossing events with negative polarity in the N400 time window for a mismatching dative argument compared to a mismatching accusative argument. By contrast, the proportion of threshold crossing events with positive polarity was smaller for dative in the P600 time window. We argue that this difference is due to the phenomenon of "free dative" in German. This result also shows that the SRA provides a useful tool for revealing ERP differences that cannot be discovered using the traditional voltage average analysis.

A magnitude code common to numerosities and number symbols in human intraparietal cortex.

Activation of the horizontal segment of the intraparietal sulcus (hIPS) has been observed in various number-processing tasks, whether numbers were conveyed by symbolic numerals (digits, number words) or by nonsymbolic displays (dot patterns). This suggests an abstract coding of numerical magnitude. Here, we critically tested this hypothesis using fMRI adaptation to demonstrate notation-independent coding of numerical quantity in the hIPS. Once subjects were adapted either to dot patterns or to Arabic digits, activation in the hIPS and in frontal regions recovered in a distance-dependent fashion whenever a new number was presented, irrespective of notation changes. This remained unchanged when analyzing the hIPS peaks from an independent localizer scan of mental calculation. These results suggest an abstract coding of approximate number common to dots, digits, and number words. They support the idea that symbols acquire meaning by linking neural populations coding symbol shapes to those holding nonsymbolic representations of quantities.

The impact of symbolism on immunogenetics: an application to HLA.

The genes coding for the class I human lymphocyte antigens (HLA) are located on chromosome 6. These antigens are involved with the immunological interaction between cells. In some immunogenetic systems, such as HLA in humans, genes are defined by antibody/antigen reaction and are denoted by single symbolic identifiers. This symbolization assumes a one-to-one correspondence between antibodies, antigens and genes. Recent molecular studies, however, suggest that HLA antibody/antigen reaction is complex and most HLA class I specific antibodies may not uniquely identify a single allelic product. Where cross-reactivity is present in an immunogenetic system it is important to label each reagent with symbols corresponding to all genes coding for antigens with which the reagent will react. The problems of cross-reactive groups and unexplained linkage relations may be elucidated by the redefinition and clarification of certain HLA antigens. A computer program can suggest such labelling schemes using input given by phenotype reaction patterns with a panel of reagents. When this program was applied to data on the class I HLA antigens a genetic model was suggested that differs somewhat from the currently accepted model. The new model is able to predict what would appear as linkage relations in the accepted model. Our methodology can provide alternate models to guide in typing cloned genes in terms of the HLA locus and alleles.

Perceptual symbol systems.

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statistics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement recording systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During perceptual experience, association areas in the brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The storage and reactivation of perceptual symbols operates at the level of perceptual components--not at the level of holistic perceptual experiences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a common frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspection (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and abstract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinatorially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a perceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal symbol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored.

Vested interest, symbolic politics, and attitude-behavior consistency.

Considerable research suggests the relevance of vested interest for attitude-behavior consistency. Conversely, symbolic politics theory holds that self-interest is irrelevant for attitude valence and related attitude phenomena. Rather, attitudes acquired early in life generalize to other issues and motivate actions, even actions contrary to self-interest. The present research replicates and extends the findings of an earlier symbolic politics study (D. O. Sears, C. P. Hensler, & L. K. Speer, 1979) on the mandated busing of school children (N > 1,300). Analysis of the archival data revealed that vested interest is a significant moderator of (racial) attitude-criterion consistency and of attitude-behavior consistency as well. The results are taken as supportive of both the vested interest and the symbolic politics orientations and form the basis of a position that suggests both schools of thought can coexist.

Vested interest and symbolic politics--observations and recommendations: reply To Sears (1997).

In his comment on the author's original article (W. D. Crano, 1997) on vested interest, symbolic politics, and attitude-behavior consistency, D. Sears (1997) concentrated on 3 important features of the original study: the logic of the analytic design, the strength of effects and, more broadly, the possibility that the apparent discontinuity between survey and laboratory findings on self-interest and attitude may reside in respondent characteristics. In response, it is argued that (a) the analytic logic, although at variance with that used in survey studies of symbolic politics, is appropriate, logical, and in conformance with standard practice; (b) the predicted effects reported are both statistically and practically significant; (c) the discontinuity between laboratory and field research may be more apparent than real; but (d) a more intense integration of self-interest and symbolic politics--a suggestion made in the original article--is precisely what is needed.
