KASER: Knowledge Amplification by Structured Expert Randomization.

In this paper and attached video, we present a third-generation expert system named Knowledge Amplification by Structured Expert Randomization (KASER) for which a patent has been filed by the U.S. Navy's SPAWAR Systems Center, San Diego, CA (SSC SD). KASER is a creative expert system. It is capable of deductive, inductive, and mixed derivations. Its qualitative creativity is realized by using a tree-search mechanism. The system achieves creative reasoning by using a declarative representation of knowledge consisting of object trees and inheritance. KASER computes with words and phrases. It possesses a capability for metaphor-based explanations. This capability is useful in explaining its creative suggestions and serves to augment the capabilities provided by the explanation subsystems of conventional expert systems. KASER also exhibits an accelerated capability to learn. However, this capability depends on the particulars of the selected application domain. For example, application domains such as the game of chess exhibit a high degree of geometric symmetry. Conversely, application domains such as the game of craps played with two dice exhibit no predictable pattern, unless the dice are loaded. More generally, we say that domains whose informative content can be compressed to a significant degree without loss (or with relatively little loss) are symmetric. Incompressible domains are said to be asymmetric or random. The measure of symmetry plus the measure of randomness must always sum to unity.

Social deviance in autism: a central integrative failure as a model for social nonengagement.

Clinically, adult autistic and PDD individuals appear to have an uneasy relationship with their social environment no matter how much developmental progress they make. Many can work at modest jobs, many more do not, and even fewer are interested enough in the human environment to cohabitate and/or marry. A conversation with a young autistic man of 20 about a trip to visit a relative focuses more on the time the train left and how late it was in hypermnestic detail, including all details except the affective environment or the relationships to human beings. This is the human significance of the term autism. Autistics can speak and reference, but they seem not to understand the social requirements of a human interchange. If they do know it, they know it in a fragmentary or rudimentary way devoid of subtlety or nuance. Whatever we mean by social intercourse and whatever functions subsume it, they seem to emerge in interaction with cognition and language. They develop apace as human traverse those first 3 years of life and as they reach social maturity in adolescence. Autistic children appear not to integrate their knowledge of things in a representation that includes emotional and cognitive elements. They do not seem to understand that words necessarily refer to things of this world that others are also referencing in their words and sentences--shared reference is not natural to them. Intersubjectivity as a feature of common code use is not tacit or explicit in their behavior. They similarly do not use social referencing in the way in which normals do, and although they show some attachment to people, they seem to do so without benefit of affective display leading to reciprocity. There is little notion of the external that makes another human being distinguishable from a thing. Their treasured objects in early childhood are hard and lack comforting proximal receptor attractiveness as in normals. Hobson's extensive studies have elaborated a notion about the autistic child's knowledge of person. He comments on the lack of integration of the verbal and visual situational ties in which affective expression emerges and functions. He also comments on the deictic inabilities, inferring that the "I," "you," and "he" references do not have any significance for such children. We would like to note that while Vygotsky and others have observed that speech comes from the world of people, language comes from the maturing organism as an innate propensity.(ABSTRACT TRUNCATED AT 400 WORDS)

Substance abuse in adolescent mothers: strategies for diagnosis, treatment and prevention.

Adolescent drug addiction and alcohol abuse are on the rise in this country. Teenagers of all races, socioeconomic groups and both genders have become avid experimenters with a full spectrum of substances, including alcohol, marijuana, stimulants, cocaine and hallucinogens. A diagnosis of addiction requires familiarity with the normative trends of adolescent behavior, as well as deviations from these trends. Moreover, an adolescent mother with a drug addiction problem confronts the additional burden of fostering adaptive developmental patterns in her infant. Treatment techniques such as previewing, which empowers through the representation and enactment of future outcomes, have helped addicted teenage mothers relinquish drug use and adopt more mature caregiving behaviors.

Do familiar landmarks reset the global path integration system of desert ants?

It is often suggested that animals may link landmark memories to a global coordinate system provided by path integration, thereby obtaining a map-like representation of familiar terrain. In an attempt to discover if desert ants form such associations we have performed experiments that test whether desert ants recall a long-term memory of a global path integration vector on arriving at a familiar food site. Ants from three nests were trained along L-shaped routes to a feeder. Each route was entirely within open-topped channels that obscured all natural landmarks. Conspicuous artificial landmarks were attached to the channelling that formed the latter part of the route. The homeward vectors of ants accustomed to the route were tested with the foodward route, either as in training, or with the first leg of the L shortened or extended. These ants were taken from the feeder to a test area and released, whereupon they performed a home vector. If travelling the latter part of a familiar route and arriving at a familiar food site triggers the recall of an accustomed home vector, then the home vector should be the same under both test conditions. We find instead that the home vector tended to reflect the immediately preceding outward journey. In conjunction with earlier work, these experiments led us to conclude in the case of desert ants that landmark memories do not prime the recall of long-term global path integration memories. On the other hand, landmark memories are known to be linked to local path integration vectors that guide ants along a segment of a route. Landmarks thus seem to provide procedural information telling ants what action to perform next but not the positional information that gives an ant its location relative to its nest.

Level of object representation and psychic structure deficit in obese persons.

The structural deficit and external regulation hypotheses of addiction state that addicts do not have adequate psychic structure with which to regulate painful affects internally. They instead use their drug of choice as an external regulator to self-medicate painful affects. This study tests whether the hypotheses can be applied to obese persons, for whom food may be the drug of choice. The level of object representation of 22 moderately obese and 24 normal weight subjects was compared using the Blatt Family Interaction Questionnaire. The mean level of object representation of both parents was lower for the obese subjects than for the normal-weight subjects. This finding supports the structural deficit and external regulation hypotheses of food addiction.

Narcissistic personality disorder in an identical twin.

An identical twin with a narcissistic personality disturbance was analyzed. Clinical and metapsychological issues were discussed. Phenomena of narcissistic pathology and twinship clarify one another. Persistence of the twin as a need-satisfying, mirroring, idealized object interferes with the maternal symbiosis, and the separation-individuation experience. If any object, be it twin, mother, nurse or sibling, retards individuation, there may be instability of the self-representation as well as faulty development of ego and superego structures. Confusing and primitive identifications, as occur in twinship, impair the more stabilizing identifications of the oedipal period, and promote narcissistic character malformation.

Computer-assisted, fluoroscopy-based ventral spondylodesis of thoracolumbar fractures.

OBJECTIVE: To design and evaluate a novel computer-assisted, fluoroscopy-based planning and navigation system for minimally invasive ventral spondylodesis of thoracolumbar fractures. MATERIALS AND METHODS: Instruments and an image intensifier are tracked with the SurgiGATE navigation system (Praxim-Medivision). Two fluoroscopic images, one acquired from anterior-posterior (AP) direction and the other from lateral-medial (LM) direction, are used for the complete procedure of planning and navigation. Both of them are calibrated with a custom-made software to recover their projection geometry and to co-register them to a common patient reference coordinate system, which is established by attaching an opto-electronically trackable dynamic reference base (DRB) on the operated vertebra. A bi-planar landmark reconstruction method is used to acquire deep-seated anatomical landmarks such that an intraoperative planning of graft bed can be interactively done. Finally, surgical actions such as the placement of the stabilization devices and the formation of the graft bed using a custom-made chisel are visualized to the surgeon by superimposing virtual instrument representations onto the acquired images. The distance between the instrument tip and each wall of the planned graft bed are calculated on the fly and presented to the surgeon so that the surgeon could formalize the graft bed exactly according to his/her plan. RESULTS: Laboratory studies on phantom and on 27 plastic vertebras demonstrate the high precision of the proposed navigation system. Compared with CT-based measurement, a mean error of 1.0 mm with a standard deviation of 0.1 mm was found. CONCLUSIONS: The proposed computer assisted, fluoroscopy-based planning and navigation system promises to increase the accuracy and reliability of minimally invasive ventral spondylodesis of thoracolumbar fractures.

The child's active role in mother-child, father-child psychotherapy: a psychodynamic approach to the treatment of relational disturbances.

The short-term mother-child and father-child psychoanalytic psychotherapy assumes that children develop specific types of relationships with each parent, as well as with the parenting couple. The model integrates an intra-psychic, object-relational view with an interpersonal perspective to the treatment of relational disturbances in childhood. The same therapist meets with the mother-child, father-child dyads on a weekly basis, along with regular meetings with the parental dyad. The model focuses on the developmentally prelatency child's need for the active participation of both parents in the here-and-now shared experiences of the therapeutic process. The participants express, in interactions and in enactments, various contents and meanings of their specific patterns of relations. The therapist addresses the behaviours as well as the meanings of relations, thus promoting reflective understanding and experiential changes in self, other, and self-other relations. The child's active and different participation with each parent is the main change-promoting factor. The child uses mainly the medium of play to express his/her needs and to mobilize the therapist's help. The therapist's access to the different dyads is utilized to better understand the explicit and implicit relational themes. The therapist supports the co-construction of new and different behaviour patterns and the co-creation of additional meanings to representations. The setup fosters the child's active participation in each dyad's growth-promoting changes.

The superego concept. Part II: Superego development, superego pathology summary.

From its inception the superego concept has been historically at the center of a process of scientific convergence-yet it has always presented difficulties in conceptualizing. In this paper, a condensed literature review selectively explore: (1) Freud's fundamental contributions to this concept; (2) major trends in the psychoanalytic exploration of the concept, as they derived from Freud's germinal ideas and; (3) some "stumbling blocks" which may have interfered with efforts at intergration of the superego concept. An object-relational frame of reference, incorporating Kernberg's recent contributions and his efforts at integration in this field at large, as well as Jacobson's contributions as they relate to superego concept in particular are briefly considered. Such a frame of reference is then applied in an effort at describing a sequential development of the superego in four progressively differentiated and integrated phases: (1) agressively derived primitive sadistic superego forerunners; (2) integration of aggressively derived, primitive superego forerunners and ideal self-object representations; (3) oedipally-derived superego and (4) post-oedipal superego individualization. Toward the end some succinct considerations regarding superego pathology are given and paths for possible further integration and exploration are suggested.

Weak hierarchies associated with similarity measures--an additive clustering technique.

A new and apparently rather useful and natural concept in cluster analysis is studied: given a similarity measure on a set of objects, a sub-set is regarded as a cluster if any two objects a, b inside this sub-set have greater similarity than any third object outside has to at least one of a, b. These clusters then form a closure system which can be described as a hypergraph without triangles. Conversely, given such a system, one may attach some weight to each cluster and then compose a similarity measure additively, by letting the similarity of a pair be the sum of weights of the clusters containing that particular pair. The original clusters can be reconstructed from the obtained similarity measure. This clustering model is thus located between the general additive clustering model of Shepard and Arabie (1979) and the standard hierarchical model. Potential applications include fitting dendrograms with few additional nonnested clusters and simultaneous representation of some families of multiple dendrograms (in particular, two-dendrogram solutions), as well as assisting the search for phylogenetic relationships by proposing a somewhat larger system of possibly relevant "family groups", from which an appropriate choice (based on additional insight or individual preferences) remains to be made.

Effects of early mother-twin relationships from birth to age 3, on twin bonding.

Findings from an earlier phase of this research project clearly pointed to the mother's psychological adaptation inherent to the specificities of triadic interaction. Mothers' attitudes were classified in a typology ranging from "early twinness" where the two babies are treated as though they were a single unit, to attempt to create two dyadic relationships. The current program deals with the effects of the type of parent-child relationship at one year on the emergence of twin bonding. Sixty-eight families of twins (26MZ, 24DZ same sex, 18DZ different sex) are followed up from birth to the age of 3 using a method based on clinical interviews, videotaped observations, and questionnaires. The data cover mothers' rearing attitudes towards organization of babycare and outward signs of twinness, maternal representations of the relationship between the twins and observation of the children's interaction in a standardized game situation. The findings are discussed in terms of zygosity, and parental SCS.

Multiple identities and the integration of personality.

Life-history interviews show narrators to shift among multiple, often contradictory self-representations. This article outlines a model that accounts for how a relatively small set of self-symbols and metaphors can form a grammar-like system that simultaneously defines and integrates multiple identities. Drawing on generative theories from linguistics, anthropology, and music, the model proposes that this system provides a unitary deep structure that can be configured in various arrangements to yield multiple surface structures. Each "surface" identity constructs an individual's emotions and social relations--and what he or she accepts as "Me" and rejects as "not-Me"--into a distinct pattern, with identity per se appearing as a dialogic or fugue-like structure of opposed voices. Study-of-lives interviews conducted by the author in urban America and rural Morocco are used to present the model and to demonstrate the pivotal role played by multistable or "structurally ambiguous" symbols in anchoring reversible self-representations which integrate personality as a system of organized contraction. The musical analogy is emphasized in order to build a bridge toward current research in cognitive science and toward efforts to formulate a "state integration" theory of personality development.

Religious patients' metaphors in the light of transference and countertransference considerations.

The verbal material of religious individuals in psychotherapy is laden with metaphors, folkloristic themes, and literary allusions whose meanings are generally deemed adequately elucidated by analysis of their symbolic content, generally in terms of the classic psychosexual conflict model. Contemporary psychoanalytic models demand that such material be further examined in terms of the level and quality of object relations and representation that characterize such content, and with an eye toward the influence of early, preverbal intersubjective factors that, by nature, tend to attain a minimal amount of psychic representation. These factors add richness and complexity to our overall understanding of the religious personality. The expanded role of countertransference as a tool for comprehending prerepresentational states, and the modes in which these are communicated, helps to outline new dimensions of religious object experience.

The place of psychodynamic theory in developmental psychopathology.

Psychoanalysis ushered in this century. Will its influence on developmental psychopathology end in the next? The paper explores some critical obstacles in the way of psychodynamic research, including the fragmentation of psychoanalytic theory. the relative independence of theory from its clinical and empirical base, the predominance of inductive scientific logic, the polymorphous use of terms, the privacy of clinical data, the dominance of the reconstructionist stance, and the isolation of psychoanalysis from psychology and neurobiology. Notwithstanding these limitations, core psychoanalytic precepts are not only consistent with some of the most important advances of the last decade but may also be helpful in elaborating these new discoveries in the next century. Psychoanalysis is centered on the notion that complex, conflicting, unconscious representations of mental states constitute a key facet of normal and abnormal development. This notion retains its power, and deserves a prominent position among the major frames of reference to guide developmental science in the next century.

Parental reflective functioning: an introduction.

Reflective functioning refers to the essential human capacity to understand behavior in light of underlying mental states and intentions. The construct, introduced by Fonagy, Steele, Steele, Moran, and Higgitt in 1991, and elaborated by Fonagy and his colleagues over the course of the next decade, has had an enormous impact on developmental theory and clinical practice. This paper introduces the construct of parental reflective functioning, which refers to the parent's capacity to hold the child's mental states in mind, and begins with a review of Fonagy and his colleagues' essential ideas regarding the reflective function. Next, the applicability of this construct to parental representations of the child and the parent-child relationship is considered. A system for coding parental reflective functioning, which will serve as the organizing framework for this special issue, is described. Finally, the three papers that make up this special section are introduced.

A process view of the self.

This paper further develops the concept of the self as experiential being, and its relevance for an understanding of psychopathology. It is proposed that the self, or 'I', processes and regulates its experiences by means of three modalities that are dynamically interrelated throughout life: exchanges/boundaries, internal mirroring/affective awareness, and the representational space. It is further proposed that pathology develops when these processes of self-regulation go wrong. As a result, different psychopathological positions are identified which, in the case of severe disorders, require a distinctive initial approach to therapy.

Supernumerary tendons of the abductor pollicis.

During a study of variants of the tendon of the abductor pollicis longus (APL) muscle, in 1 of 110 upper extremities prepared, we recorded the rare finding of a division of the APL muscle tendon into 7 sections in the first tunnel. Whereas the actual main tendon inserted at the base of the first metacarpal bone, as depicted in the textbooks, the supernumerary tendons attached to the fascia of the opponens pollicis muscle to the radial edge of the abductor pollicis brevis muscle and to the dorsoradial third of the base of the first metacarpal bone. All accessory tendons were arranged in a radial formation around the main tendon within the same synovial sheath, but the main tendon occupied a separate compartment. In 80% of the upper extremities prepared for this study, the classical description of the abductor tendon did not apply. The classical representation of a single abductor tendon applied to only 20% of the upper extremities examined. In about one third of the wrists prepared, the first tunnel was clearly divided by a septum, so that 2 or more osteofibrous tunnels were present within the main tunnel. The number, thickness and length of such accessory tendons have a functional significance in the development of de Quervain's stenosing tendovaginitis and possibly also have a practical significance, as they may be regarded as a source of transplant material for plastic reconstructions.

Human morality and temperament.

This chapter has tried to make two points. First, the concept of morality refers to a developmental cascade of phenomena whose essential features are (a) inhibition of punished acts; (b) a representation of prohibited actions; (c) the emotions of uncertainty, empathy, shame, and guilt; (d) the semantic concepts of good and bad; (e) accepting the moral obligations of social categories; and (f) the concepts of fairness and the ideal. The inhibition of prohibited actions and the cognitive representation of prohibited behaviors, as well as the affect states that follow violations, appear by the end of the second year of life. The concepts of good and bad appear early in the third year, the experience of guilt and awareness of social categories by 4-6 years, and the notions of fairness, the ideal, and relational social categories during the school years. Second, some of the variation in the intensity and frequency of the moral emotions is attributable to the child's temperament. Eleven-year-old children who had been high-reactive infants and admitted to feelings of guilt when they violated a family standard were cortically and autonomically more aroused than the low reactives who reported equally frequent experiences of guilt. Further, high reactives who were perceived by their mothers as highly sensitive to punishment were biologically more aroused than high reactives perceived as less sensitive. Both universal developmental phenomena tied to brain maturation and temperamental variation associated with neurochemistry contribute to the complex phenomena that constitute the moral domain. The role of affect in promoting the adherence to standards remains controversial. Kant believed that people acted morally because acceptance of the categorical imperative required proper behavior-reason was the guardian of social harmony. Peirce and Dewey, by contrast, argued that anticipation of the emotions of anxiety, shame, and guilt motivated loyalty to the community's ethical standards. The fact that adults pay to watch a film that they know will generate a deep feeling of sadness--an emotion most do not seek or welcome in their daily lives--and will remark that they enjoyed the movie warrants an explanation. One possibility is that the experienced emotion affirms their moral values. The Australian film The Rabbit Proof Fence describes three aboriginal sisters who have been taken from their mother to a camp a thousand miles away to be socialized in Australian values. The three girls run away, and most of the film illustrates the hardships that they endure and their close escapes from the authorities who are pursuing them as they walk the thousand miles to reach their home. The audience's empathic sadness for the children affirms their moral belief that children should love their parents and miss their home. I suspect that those in the audience who felt the most intense sadness would praise the film with greater enthusiasm than those who had muted feelings. Because sadness is an emotion that few enjoy or try to attain, there must be another reason for deciding that the film was gratifying. The affirmation of one's moral beliefs could be that source of gratification. The tension between the importance of a rational and the importance of an affective basis for morality is seen in modern industrialized societies where the balance between the feeling of virtue that follows enhancing another and the pleasure that follows the enhancing of self has shifted toward favoring the latter state. Increasing numbers of Americans do not regard their gender, ethnicity, vocation, place of residence, or friendships or the religion of their parents as distinctive sources of virtue. As a result, they are freed from the moral obligations that were attached to these categories in the past and rely primarily on the anticipation of sensory delight and self-enhancement as guides for action and sources of reassurance that they are managing their lives correctly. Although it is likely that future scientists will synthesize a drug that blocks feelings of guilt without affecting the knowledge that an act is wrong, it is less certain that broad use of this drug would eliminate loyalty to the mutual obligations that make a society habitable. Nonetheless, a posture of vigilance is appropriate, for humans, unlike gorillas, can hold representations of envy, hostility, and anger, even toward those whom they have never met, for a very long time. Therefore, empathy and the anticipation of guilt or shame may restrain rudeness, dishonesty, and aggression when reason fails.
