Color measurement and color theory: II. Opponent-colors theory

Quantitative opponent-colors theory is based on cancellation of redness by admixture of a standard green, of greenness by admixture of a standard red, of yellowness by blue, and of blueness by yellow. The fundamental data are therefore the equilibrium colors: the set A₁ of lights that are in red/green equilibrium and the set A₂ of lights that are in yellow/blue equilibrium. The result that a cancellation function is linearly related to the color-matching functions can be proved from more basic axioms, particularly, the closure of the set of equilibrium colors under linear operations. Measurement analysis treats this as a representation theorem, in which the closure properties are axioms and in which the colorimetric homomorphism has the cancellation functions as two of its coordinates.Consideration of equivalence relations based on opponent cancellation leads to a further step: analysis of equivalence relations based on direct matching of hue attributes. For additive whiteness matching, this yields a simple extension of the representation theorem, in which the third coordinate is luminance. For other attributes, precise representation theorems must await a better qualitative characterization of various nonlinear phenomena, especially the veiling of one hue attribute by another and the various hue shifts.     

Aspects of psychoanalytic theory: drives, defense, and the pleasure-unpleasure principle

Freud explained certain fundamentally important aspects of mental motivation by assuming the existence of two drives, one libidinal and the other aggressive/destructive. Elements of this theory that seem invalid are identified and discussed, and revisions are proposed that appear to have more validity and greater clinical usefulness.     

The current status of the psychoanalytic theory of instinctual drives. II: The relation of the drive concept to structures, regulatory principles, and objects

There has been and continues to be some degree of failure to recognize the effects of the introduction of the ego-id-superego model on the drive construct. In particular, some of the criticisms of drive theory fail to take cognizance of the structural position of drives. Drives, as an aspect of id, are more clearly separated from behavior conceptually than many discussions imply. Drive energy is a different concept from drive. Especially in the area of the governance of drives by the regulatory principles of mental functioning some improvement in clarity and utility seems possible through the use of different, more sophisticated models. Difficulties in the concept of objects appear to underlie considerable controversy in psychoanalysis today. I have here attempted to clarify the concept of drive objects, as a step in resolving the broader issues.     

A misinterpreted psychoanalyst: Herbert Silberer and his theory of symbol-formation

The primary aim of this article is to give a more detailed exposition of the cultural, personal, and theoretical contexts in which the Viennese psychoanalyst, Herbert Silberer's theories were born. When assessing the broader picture that this approach offers, it can be concluded that Silberer was an innovative thinker who inspired several of his contemporaries. Recognized in many respects by the society and scholars of this time, he represented quite a different viewpoint that was significantly influenced by several forms of Western esoteric thinking. Yet his main aim was to contribute to the field of psychoanalysis and develop a theory in which rationalistic psychoanalytic interpretations were combined with nonreductive approaches to mystical experiences. Silberer's name is frequently mentioned in a specific context in which his tragic suicide is emphasized rather than his innovations. Upon evaluating the materials recording Silberer's private life, it seems very likely that his suicide was not triggered by the criticism of Freud alone. Silberer's family affairs, his relationship with his father, and his financial and professional struggles could have all contributed to his tragic decision. This paper contends that Silberer's oeuvre deserves greater attention and must be evaluated based upon its own merit.     

In the shadow of a controversy: Freud and Ferenczi 1925‐331

In recent literature, Freud's relation with pioneers of psychoanalysis has been reevaluated. This paper describes the evolution of the relation between Freud and Ferenczi during their most controversial period‐1925‐33. The consequences of this evolution on psychoanalytic theory and practice are shown. The links between events of the protagonists' lives, their refl ections about them, and the resulting theoretical elaboration (e.g. on homosexuality, female sexuality, problems of separation) are also taken into account. This work is essentially based on their recently published correspondence.     

The relationship of Clark L. Hull's hypnosis research to his later learning theory: The continuity of his life's work

What has been missing in previous historical accounts of Clark L. Hull is a view of his life's work as an integrated whole. This paper contributes to that end by relating his hypnosis research and theory during the years 1921 to 1933 to the developing behavioral orientation of his learning theory. In addition, this paper relates his work historically and conceptually to the theory of idemotor action endorsed by William James and a number of other nineteenth-century psychologists, and transmitted by Hull into the stimulus-response terminology of the 1930s.     

The current status of the psychoanalytic theory of instinctual drives. I: Drive concept, classification, and development

The evolution of Freud's theory of instinctual drives, with the accompanying models of a mental apparatus, is remarkable for its tenacious adherence to addressing the fundamental problems of human psychology, here phrased as the problems of body-mind-environment relationships. The concept of instinctual drives continues to be one of the most pervasive concepts of psychoanalysis, weathering considerable attack over the last several decades, although losing some clarity in the process. I have cited and discussed as basic issues of the concept of instinctual drives: the relationship of observational data and theoretical constructs in psychology; whether our construct of drives is or should be or can be purely psychological; the problem of conceptualizing the ontogenetic origin of mind; the issues of the "force-meaning conjunction" and the problem of psychic energy in psychoanalytic constructs; and the relation of our concept of instinctual drives to the concept of instincts in general. It seems that progress with these fundamental issues might be made by utilizing models that are more homologous with present knowledge in related fields than is Freud's reflex arc model of the nervous system, in order to build a better drive construct within the framework of psychoanalysis. The classification of instinctual drives remains a problem. Clinically, aggression seems to be a factor in conflict, very much like sexuality. Despite widespread acceptance of the idea of aggression as simply parallel to sexuality in all respects, there are major discrepancies. Perhaps aggression cannot be viewed as a drive after all; perhaps our drive construct needs to be modified to accommodate aggression. Certainly, controversy in this area has interfered with the production of good clinical studies which could begin to increase our understanding of aggression and its place in the human personality. The psychoanalytic theory of drive development has probably undergone less change in the last forty years than other aspects of drive theory, although careful observational work has led to alterations of our views of the age of onset of genital awareness, of female sexual development and function, and of the latency period. This is the conclusion of the first of two papers examining the post-Freud development of the theory of instinctual drives in psychoanalysis. The companion paper follows on p. 402 of this issue of The Psychoanalytic Quarterly.     

In the shadow of giants: The work of mario pieri in the foundations of mathematics

A discussion is given of the research in the foundations of mathematics of Mario Pieri (1860-1913) and how it compares with the works of Christian von Staudt (1798-1867), Giuseppe Peano (1858-1932), David Hubert (1862-1943), and Alfred Tarski (1902-1983). The author demonstrates that the acceptance of Pieri’s results was overshadowed by the research of these four scholars, and argues that Pieri’s work merits a more significant place in the history of mathematics than it currently enjoys     

In the shadow of the boss's boss: effects of supervisors' upward exchange relationships on employees

Dyadic relationships in an organizational hierarchy are often nested within one another. For instance, the relationship between a supervisor and an employee is nested within the relationship between that supervisor and his or her boss. In that context, the authors propose that the supervisor's relationship with his or her boss (leader-leader exchange) moderates the effects of the supervisor's relationship with the employee (leader-member exchange). Specifically, the authors argue that leader-member exchange has a stronger positive effect on employees' attitudes toward the organization and its customers when leader-leader exchange is higher. Cross-level analysis of data from 581 frontline nurses and 29 supervisors in a midwestern hospital supports this contention. Implications for research and practice are discussed.
