Cognitive psychology and modern physics: Some analogies

Abstract

Patterns in physics and psychology are often related. This paper examines such relations on two levels. First, a survey is made of the various possible relations between physics and psychology and, secondly, a series of analogies between patterns in modern physics and cognition is presented. The analogies pertain both to the theory of relativity (both special and general) and to quantum mechanics. While the different analogies noted are argued for independently from one another, together they do present some unified patterns. It is argued that the analogies may be useful in opening up avenues for new conceptual bameworks in psychology. In particular, they are linked to a possible critique of the representational view of mind.     

The psychology of inferring conditionals from disjunctions: A probabilistic study

There is a new probabilistic paradigm in the psychology of reasoning that is, in part, based on results showing that people judge the probability of the natural language conditional, if $A$then $B$, $P\left(ifAthenB\right)$, to be the conditional probability, $P(B\mid A)$. We apply this new approach to the study of a very common inference form in ordinary reasoning: inferring the conditional if not-$A$then $B$ from the disjunction $A$ or $B$. We show how this inference can be strong, with $P$(if not-$A$then $B$) “close to” $P\left(AorB\right)$, when $A$ or $B$ is non-constructively justified. When $A$ or $B$ is constructively justified, the inference can be very weak. We also define suitable measures of “closeness” and “constructivity”, by providing a probabilistic analysis of these notions.     

Contextualized self: when the self runs into social dilemmas

Research on the construction of self and of others has indicated that the way that individuals construe themselves and others exerts an important influence on their cognition, emotion, and even behavior. The present study extends this line of research to mixed-motive situations in which short-term individual and long-term collective interests are at odds. In addition, this study associates the importance of context interdependence, and specifically its interaction with independent self-construal, with an individual's cooperative behavior. We used a priming task to manipulate the level of self-construal and also manipulated the degree of interdependent context by giving participants a chance to assign rewards either to their group members or to themselves alone. The results showed that when participants received interdependent (as opposed to independent) self-construal priming, they consistently contributed highly, regardless of context manipulation. In contrast, those primed with an independent self-construal contributed less in the investment game, but only when placed in a context where group members were encouraged to think about their individual (versus mutual) fate. In this situation they contributed the least to the group in the game. These findings indicate that independent self-construal in a low interdependence context produces the most competitive behavior. The results also showed that how participants felt about their interaction with other group members mediated the effect of context interdependence on cooperative behavior, and possibly that was especially the case for independent self-construal. The results demonstrate that the self can be contextualized and embedded in the social contexts and symbolic systems within which people live.     

When causality does not imply correlation: more spadework at the foundations of scientific psychology

Experimental research in psychology is based on an open-loop causal model which assumes that sensory input causes behavioral output. This model was tested in a tracking experiment where participants were asked to control a cursor, keeping it aligned with a target by moving a mouse to compensate for disturbances of differing difficulty. Since cursor movements (inputs) are the only observable cause of mouse movements (outputs), the open-loop model predicts that there will be a correlation between input and output that increases as tracking performance improves. In fact, the correlation between sensory input and motor output is very low regardless of the quality of tracking performance; causality, in terms of the effect of input on output, does not seem to imply correlation in this situation. This surprising result can be explained by a closed-loop model which assumes that input is causing output while output is causing input.     

Inquiry into intentional systems I: Issues in ecological physics

Summary The role of intention in guiding the behavior of goal-directed systems is a problem that continues to challenge behavioral science. While it is generally agreed that intentional systems must be consistent with the laws of physics, there are many obvious differences between inanimate, physical systems and sentient, intentional systems. This suggests that there must be constraints over and above those of physics that govern goal-directed behavior. In this paper it is suggested that generic properties of self-organizing mechanisms may play a central role in the origin and evolution of intentional constraints. The properties of self-organizing systems are first introduced in the context of simple physical systems and then extended to a complex (biological) system. Whereas behavior of an inanimate physical system is lawfully determined by force fields, behavior of an animate biological system is lawfully specified by information fields. Biological systems are distinguished from simple physical systems in terms of their ubiquitous use of information fields as special (biological and psychological, social, etc.) boundary conditions on classical laws. Unlike classical constraints (boundary conditions), informational constraints can vary with time and state of the system. Because of the nonstationarity of the boundary conditions, the dynamic of the system can follow a complex trajectory that is organized by a set of spatially and temporally distributed equilibrium points or regions. It is suggested that this equilibrium set and the laws that govern its transformation define a minimal requirement for an intentional system. One of the benefits of such an approach is that it suggests a realist account for the origin of semantic predicates, thereby providing a basis for the development of a theory of symbolic dynamics. Therefore, the principles of self-organization provide a comprehensive basis for investigating intentional systems by suggesting how it is that intentions arise, and by providing a lawful basis for intentional behavior that reveals how organisms become and remain lawfully informed in the pursuit of their goals.     

The concept of a proposition in classical and quantum physics

A proposition is associated in classical mechanics with a subset of phase space, in quantum logic with a projection in Hilbert space, and in both cases with a 2-valued observable or test. A theoretical statement typically assigns a probability to such a pure test. However, since a pure test is an idealization not realizable experimentally, it is necessary — to give such a statement a practical meaning — to describe how it can be approximated by feasible tests. This gives rise to a search for a formal representation of feasible tests, which leads via mixed tests (weighted means of pure tests) to vague tests (convex sets of mixed tests). A model is described in which the latter form a continuous lattice; the pure and mixed tests are the maximal elements and the feasible tests form a basis. Each type of test has its own logic; this is illustrated by the passage from mixed tests to pure tests, which corresponds to the transition from L to classical logic.This work was supported by a grant from the National Research Council of Canada.     

Indeterminacy and consciousness in the creative process: What quantum physics has to offer

The quantum view of creativity, based on Goswami's idealistic interpretation of quantum physics, is presented. It provides a resolution for two controversial areas of creativity theory and research: the “aha”; experience and the role of consciousness. According to the quantum model, the mind‐brain consists of classical and quantum functions and structures. The source for creative ideation lies in the quantum realm in the form of unlearned coherent superpositions or states of simultaneous multiple possibilities. While access of coherent superpositions (CohS) are susceptible to interference from classical domain functions, such as attention, the CohS itself is experienced as an altered state, facilitating creative ideation. The relationships among attention, self‐awareness, context, ambiguity, uncertainty, and conscious and unconscious perception in creative ideation are proposed to be experienced discontinuously due to an indeterminate element inherent in nature. Theoretical and empirical investigation of the above propositions is possible through quantum physics.     

Replanting the Bodhi tree: New paradigms for Buddhist philosophy from quantum physics

This study explores and assesses the nature and practice of Mindfulness-Based Cognitive Therapy (MBCT) from the perspective of Theravāda Buddhism. It is particularly concerned with how both models of training understand and apply ‘mindfulness’. The approach here is, firstly, to examine how the Theravāda understands and employs mindfulness and, secondly, to explore, and more accurately contextualize, the work of MBCT. The evaluation of MBCT in terms of the Theravāda suggests the former has both a strong affinity with, as well as some significant distinctions from, its dominant Theravādin influences.     

Potential legislative inroads into personnel psychology: Appropriate reaction measures

This article discusses an emerging interest on behalf of state legislators in the area of preemployment psychological testing. Along with describing specific legislation which has been recently introduced and defeated, public policy issues stimulating such initiatives are identified. Given the commonality of issues across all forms of testing, the importance of the psychology profession's involvement in opposing such legislation is identified and advocated.     

Quanta, quarks, and families: implications of quantum physics for family research

This paper offers recommendations for family research in light of the scientific paradigm ushered in by quantum physics in the early twentieth century. After summarizing the basic discoveries of quantum physics, the author discusses philosophical implications of these discoveries, and then presents implications for conducting scientific research about families within a post-Newtonian paradigm that emphasizes relations, process, and dynamic causation. The author argues for using complementary research models, including linear and systemic, because no one theory or methodology can illuminate fully the inscrutable nature of family processes.     

A theory of causality: Causality=interaction (as defined by a suitable quantum field theory)

In this paper I put forward a suggestion for identifying causality in micro-systems with the specific quantum field theoretic interactions that occur in such systems. I first argue — along the lines of general transference theories — that such a physicalistic account is essential to an understanding of causation; I then proceed to sketch the concept of interaction as it occurs in quantum field theory and I do so from both a formal and an informal point of view. Finally, I present reasons for thinking that only a quantum field theoretic account can do the job — in particular I rely on a theorem by D. Currie and to the effect that interaction cannot be described in (a Hamiltonian formulation of) Classical Mechanics. Throughout the paper I attempt to suggest that the widespread scepticism about the ability of quantum theory to support a theory of causality is mistaken and rests on several misunderstandings.     

Gestalt psychology: the forgotten paradigm in abnormal psychology

Gestalt views of psychopathology are almost completely ignored in mainstream psychology and psychiatry. However, a review of available evidence indicates a remarkable consistency between these views and current data from experimental psychopathology and cognitive neuroscience. This consistency is especially pronounced in the area of schizophrenia. In addition, there is a convergence of cognitive and neurobiological evidence regarding the validity of early Gestalt views of both normal brain-behavior relationships and disordered ones, as in schizophrenia. This article reviews some contributions of Gestalt psychology regarding schizophrenia and examines these views in light of more recent findings from cognitive psychology, cognitive neuroscience, and experimental psychopathology. We conclude that Gestalt theory is a viable theoretical framework from which to understand schizophrenia. Specifically, it appears that a breakdown of Gestalt organizational processes may characterize both the cognitive and the brain processes in schizophrenia.     

Putting the psychology back into psychological models: Mechanistic versus rational approaches

Two basic approaches to explaining the nature of the mind are the rational and the mechanistic approaches. Rational analyses attempt to characterize the environment and the behavioral outcomes that humans seek to optimize, whereas mechanistic models attempt to simulate human behavior using processes and representations analogous to those used by humans. We compared these approaches with regard to their accounts of how humans learn the variability of categories. The mechanistic model departs in subtle ways from rational principles. In particular, the mechanistic model incrementally updates its estimates of category means and variances through error-driven learning, based on discrepancies between new category members and the current representation of each category. The model yields a prediction, which we verify, regarding the effects of order manipulations that the rational approach does not anticipate. Although both rational and mechanistic models can successfully postdict known findings, we suggest that psychological advances are driven primarily by consideration of process and representation and that rational accounts trail these breakthroughs.
