Downward causation in fluid convection

Recent developments in nonlinear dynamics have found wide application in many areas of science from physics to neuroscience. Nonlinear phenomena such as feedback loops, inter-level relations, wholes constraining and modifying the behavior of their parts, and memory effects are interesting candidates for emergence and downward causation. Rayleigh–Bénard convection is an example of a nonlinear system that, I suggest, yields important insights for metaphysics and philosophy of science. In this paper I propose convection as a model for downward causation in classical mechanics, far more robust and less speculative than the examples typically provided in the philosophy of mind literature. Although the physics of Rayleigh–Bénard convection is quite complicated, this model provides a much more realistic and concrete example for examining various assumptions and arguments found in emergence and philosophy of mind debates. After reviewing some key concepts of nonlinear dynamics, complex systems and the basic physics of Rayleigh–Bénard convection, I begin that examination here by (1) assessing a recently proposed definition for emergence and downward causation, (2) discussing some typical objections to downward causation and (3) comparing this model with Sperry’s examples. The aim of science is not things themselves, as the dogmatists in their simplicity imagine, but the relations among things; outside these relations there is no reality knowable. – Poincaré     

Reading Loewald: Oedipus reconceived

Loewald's 'Waning of the Oedipus complex' is a watershed paper in the history of psychoanalytic thought. By means of a close reading of Loewald's paper, the author frames, discusses and clinically illustrates his understanding of Loewald's reconceptualization of the Oedipus complex. The principal elements of Loewald's reformulation include: 1) the idea that the tension between the pressures of parental infl uence and the child's innate need to establish his own capacities for originality lies at the core of the Oedipus complex; 2) the notion that oedipal parricide is driven, most fundamentally, by the child's 'urge for emancipation.' Parricide involves a revolt against, and an appropriation of, parental authority; 3) the idea that the child atones for the act of parricide by internalizing a transformed version of the child's experience of the oedipal parents. This results in an alteration of the very structure of the child's self (i.e. in the formation of the superego as the agency of autonomy and responsibility); 4) the notion that, in the child's appropriation of parental authority, he in reality 'kill[s] something vital in them [thus] contributing to their dying' and to the succession of generations; and 5) the idea that the incestuous component of the Oedipus complex involves, in health, the creation of a transitional incestuous object relationship which, over the course of one's life, mediates the interplay between undifferentiated and differentiated aspects of self and relatedness to others. The author concludes with a comparison of Freud's and Loewald's conceptions of the Oedipus complex.     

Comparing expert and novice understanding of a complex system from the perspective of structures, behaviors, and functions

Complex systems are pervasive in the world around us. Making sense of a complex system should require that a person construct a network of concepts and principles about some domain that represents key (often dynamic) phenomena and their interrelationships. This raises the question of how expert understanding of complex systems differs from novice understanding. In this study we examined individuals’ representations of an aquatic system from the perspective of structural (elements of a system), behavioral (mechanisms), and functional aspects of a system. Structure-Behavior-Function (SBF) theory was used as a framework for analysis. The study included participants from middle school children to preservice teachers to aquarium experts. Individual interviews were conducted to elicit participants’ mental models of aquaria. Their verbal responses and pictorial representations were analyzed using an SBF-based coding scheme. The results indicated that representations ranged from focusing on structures with minimal understanding of behaviors and functions to representations that included behaviors and functions. Novices’ representations focused on perceptually available, static components of the system, whereas experts integrated structural, functional, and behavioral elements. This study suggests that the SBF framework can be one useful formalism for understanding complex systems.     

Belief, hope and faith

A case of hysteria is presented in order to create a frame of reference for the author's approach to the concepts of hope, belief and faith. A difference between hope as a 'sad passion' (which is here called regressive hope) and hope as a principle of mental functioning is established. The concept of hope will at fi rst always be based on beliefs-either beliefs organised in the paranoid-schizoid position (called here fragmented and delusional beliefs)-or those organised from the depressive position (complex systems of beliefs, which end up being dogmatic); the latter typically occur in neurotics. It is suggested here that there is another possibility for hope, which is based on faith. The meaning of faith is considered here externally to the religious sense. The solid establishment of hope as a principle-based on faith-can be viewed as responsible for the opening up of creative potentials and as one of the main aims of analysis. Such an aim, however, requires the establishment of a deep relationship, both in theory and in clinical practice, between the Kleinian question of the depressive position and the Freudian question of the Oedipus complex.     

Introduction to This Special Issue: Complex Thought and Construction of Identity

This Introduction summarizes the rationale for three Special Issues in the Journal of Adult Development. The first, the present Special Issue, is on the themes of complex thought and the construction of identity. Summaries of the six empirical and theoretical articles in this first Special Issue appear below. The argument is made that work in this area adds to our knowledge about the complex network of factors present in and intersecting with adult development.     

Reliability and Validity of the Complex Postformal Thought Questionnaire: Assessing Adults’ Cognitive Development

Three studies investigated the psychometric properties of the complex postformal thought (PFT) questionnaire (Sinnott, unpublished scale, 1998; Sinnott and Johnson 1997), which is a measure of adult cognitive development. The scale was found to be moderately reliable (α = .63). To assess construct validity, a comparison of participants’ performance on the PFT scale to their performance on the Need for Cognition scale was conducted, which indicated the PFT scale is valid measure of complex thought. Factor analysis reduced the scale to three factors, which correspond to important components of PFT: Multiple Elements, Subjective Choice, and Underlying Complexities. Implications for understanding the nature of adult cognitive development and the usefulness of this new measure for research in this area are discussed.     

Aspects of Anima and Animus in Oedipal Development

This paper aims to insert the contrasexual archetype into the dynamic narrative of the Oedipus complex. Jung used the terms 'anima' and 'animus' to classify observed phenomena but did not explore the developmental origins of these phenomena in terms of personal history and experience. Some typical manifestations of anima and animus are described and shown to be rooted in the vicissitudes of Oedipal development. The contrasexual archetype is initially mediated by the oedipally loved parent and subsequent manifestations bear the imprint not only of the parent himself or herself but of the entire complex of object relationships in which Oedipal love is embedded. Successful resolution of the Oedipus complex depends on freeing the anima/animus from its Oedipal bonds so that its function as a bridge to the unconscious can be realized. This function is connected with the emergence of a symbolic capacity through which anima and animus can be recognized and valued as imaginal rather than external realities. The clinical material explores the damaging impact of a split parental couple on this process and the positive role of idealization as a stimulus to psychic development.     

Wendy's Story: analytic perspectives on J. M. Barrie's Peter and Wendy

This essay is a study of Peter and Wendy, J. M. Barrie's 1911 novel based on his 1904 play Peter Pan. Utilizing Jungian and Kleinian theory, the tale is treated as an expression of Wendy's psyche in transformation, tracking her passage into puberty and the transition from omnipotent narcissism towards depressive concern which accompanied her differentiation from idealized identification with her mother. The resultant changes in Wendy's parental imagos are given particular emphasis, especially the moves towards the integration of her split paternal imago, symbolized by Peter Pan and Captain Hook. This enables Wendy's fuller engagement with the Oedipus situation, resulting in her assimilation of unconscious aspects of the instinctual feminine. In turn, she opens to a conception of parental intercourse which is more reality orientated and allows an internal sense of coupledom vital for her own capacity to form adult relationships.     

Performances on Rey Auditory Verbal Learning Test and Rey Complex Figure Test in a healthy, elderly Danish sample--reference data and validity issues

This study presents Danish data for Rey Auditory Verbal Learning Test (RAVLT) and Rey Complex Figure Test (RCFT) from 100 subjects aged 60-87 years. Education and estimated verbal intelligence (DART score) had a significant impact on the RAVLT trial 1-5 score but not on other RAVLT measures. The RCFT copy score was significantly related to age and the DART score. On RCFT recall a highly significant difference was found between persons who could make a faultless copy and persons with incomplete copy performance. Thus, this study presents separate data for RCFT recall scores according to the subjects' copying performance (in separate tables for age and education groups). For all measures on both RAVLT and RCFT wide distributions of scores were found and the impact of this broad score range on the tests' discriminative validity is discussed. RAVLT performances for elderly were similar to previous published meta-norms, but the included sample of elderly Danes performed better on RCFT (copy and recall) than elderly from the United States.
