The role of the feedforward paradigm in cognitive psychology

Feedforward control is a process adjusting behaviour in a continuative way. Feedforward takes place when an equilibrium state is disrupted and the system has to automatically retrieve the homeostatic stable state. It also occurs when a perturbation is previewed and must be eliminated in order to achieve a desired goal. According to the most general definition, a feedforward process operates by fixing the future representation of the desired state, the achieving of which stops the process. Then, feedforward works by means of the refinement determined by successive comparisons between the actual and target products. In its applications, a feedforward process is thought to be modulated by the subject’s purpose and the environmental state. Over the years, the feedforward process has assumed different connotations in several contests of cognitive psychology. An overview of the research fields in psychology that significantly progressed with the introduction of a feedforward paradigm is provided by: (a) reviewing models in which the feedforward concept plays a fundamental role in the system control; (b) examining critical experiments related to the interaction of feedforward and feedback processes; (c) evidencing practical applications for some of the presented feedforward-based architectures.     

The emerging role of school psychology

This report relates personal experiences as they influenced the emerging role of the school psychologist, especially in Pennsylvania and Indiana from 1930 to 1970.     

The role of eye-fixation research in cognitive psychology

Eye-fixation research can be used to address issues of theoretical interest in several areas of cognitive psychology, such as linguistic processing, spatial processing, and reading. The eye-fixation behavior can lead to processing models, assuming that the eye fixates the referent of the symbol being operated on.     

On the role of behaviorism in clinical psychology

This discussion presents the viewpoints of five well-known psychologists on the role of behaviorism in clinical psychology. The article is a condensed version of a symposium presented at the 1978 annual APA convention.     

The role of James McCosh in God's exile from psychology

As a discipline of psychology coalesced during the latter half of the 19th century in American institutions of higher learning, the role of God as an explanatory force declined dramatically. Part of this story must include the role played by James McCosh, president and primary psychology professor at Princeton, 1868-1888, in assuring orthodox educated believers that the new psychology was essentially a safe endeavor and that the truths discovered therein posed no threat and ultimately would harmonize with the truths of the historic Christian faith. Several of McCosh's students later credited him with leading the way. Where McCosh led and how he did it is the focus of this article.     

Person,symbol, sociality: Towards a social psychology of cultural dynamics

Contemporary research on personality and culture has successfully mapped out major cultural differences in personality profile. However, in order to investigate the dynamic process by which culturally shaped personalities are formed, maintained, and transformed, sociality or the totality of social processes that mediate the culture–personality relationship need to be examined. A research program of a social psychology of cultural dynamics is outlined, and a computer simulation is described as an example of this metatheoretical orientation. This connectionist-based simulation suggests that there exists a physically realizable system that can generate both individual differences and culture from a stream of social interaction episodes among multiple actors. The importance of sociality in personality and culture research is emphasized.     

Maintaining the viability of counseling psychology: The role of research training

Data and trends affecting the future of counseling psychology are discussed. It h concluded that the future existence of the specialty is largely influenced by the research productivity of counseling psychologists. A major factor affecting that productivity is the quality and effectiveness of research training provided to graduate students. The empirical literature on research training is reviewed with respect to procedures for increasing research productivity. Suggestions for modifying graduate research training are discussed.     

The role of standing in the psychology of procedural justice: Towards theoretical integration

In the current chapter, the authors explore the relation between social standing and procedural justice. Standing is an important construct in procedural justice theories and tends to be broadly defined as the position that people have in social groups. It is argued that the standing construct suffers from conceptual ambiguity: In procedural justice literature two distinct interpretations of standing can be distinguished, one defining standing as intragroup status and one defining standing as the extent to which people are included in social groups. Furthermore, it is argued that research findings on the relation between standing and procedural justice are not conclusive. The authors review recent empirical findings that address these concerns, and conceptually integrate these findings. In closing, the authors outline avenues for future research that the procedural justice field may want to take, and discuss implications of the work reviewed here.     

Psychosis,symbol, affectivity 1: etiopathogenesis and treatment through analytical psychology

This is the first of two papers concerning our study into an integrated approach to psychotic disorders, conducted at the University of Palermo’s Psychiatry Unit Polyclinic over approximately 15 years. Here we will explore and reflect upon the acute psychotic condition mainly from a theoretical and conceptual perspective, while in the second paper we will explore the clinical perspective. From the point of view of psychopathology, and in the light of C.G. Jung’s conceptualization of analytical psychology, as well as calling on contributions from other authors from the systemic-relational and post-psychoanalytic field, we will clarify the ideas developed over these last few years by our team. From a more speculative perspective we will advance new interpretive hypotheses in an attempt to thoroughly understand the nature of the psychotic condition, both on a psychodynamic relational and a neuroscientific level. The paper describes how we revised our understanding of psychosis from a brain disease to a process aimed at the rearrangement of psychic functioning, as anticipated by John Weir Perry nearly 40 years ago.     

The twelfth Bartlett memorial lecture: The role of single neurons in the psychology of perception

I feel deeply honoured by your invitation to give the Bartlett lecture, and am especially glad to do so in Holland, the home of so many distinguished psychologists of sensation and perception. And there is a third reason why it has given me much pleasure, for Sir Frederick Bartlett was one of those who had an important influence on the direction of my career some 40 years ago. I had to decide whether to spend my last year at Cambridge reading psychology or physiology, so I attended a short course of introductory lectures he gave in July. About half a dozen of us sat on upright wooden chairs circled around him as he sat in an armchair, smiling benignly. The first thing he did was to tell us to close our notebooks, for he was not going to say anything that would help us to pass any exams. And I believe the very last words of his last lecture were, “So you see it is all very difficult”. I was very glad he said that, for I had in fact found it all very heavy going: my brain seemed always to be lost in clouds of uncertainty when “remembering”, “thinking”, or “perceiving” were mentioned, because there was no conceptual framework for these processes except the words themselves and others spun around them. What I was looking for were the definable quantities of physics, chemistry and even physiology, these I could handle conceptually in their geometric and functional interactions, whereas I always find a purely verbal argument about abstractions difficult to follow and impossible to believe. So this lack of any nonverbal conceptual framework was very painful.

There was one phrase I think I recall him using that particularly aroused my interest-“the effort after meaning”; intuitively this seemed to be very important, but however much effort I made the meaning never quite emerged. I had almost decided that my mistrust of words made me unsuited to a career in psychology, but all the same I put my problem about “physiology or psychology” directly to Bartlett. After finding out that I was mainly interested in problems of sensation and perception, he said he thought that E. D. Adrian's research over the last 20 years had made more difference to that subject than any results obtained from within psychology itself.
