Graphical language games: interactional constraints on representational form

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to communicate can also affect the structure and organization of symbol systems independently of cognitive change. We propose that mutual-modifiability-opportunities for people to edit or manipulate each other's contributions-is a key constraint on the emergence of complex symbol systems. We discuss the implications for models of language development and the origins of compositionality.     

Evolutionary origins of stigmatization: the functions of social exclusion

A reconceptualization of stigma is presented that changes the emphasis from the devaluation of an individual's identity to the process by which individuals who satisfy certain criteria come to be excluded from various kinds of social interactions. The authors propose that phenomena currently placed under the general rubric of stigma involve a set of distinct psychological systems designed by natural selection to solve specific problems associated with sociality. In particular, the authors suggest that human beings possess cognitive adaptations designed to cause them to avoid poor social exchange partners, join cooperative groups (for purposes of between-group competition and exploitation), and avoid contact with those who are differentially likely to carry communicable pathogens. The evolutionary view contributes to the current conceptualization of stigma by providing an account of the ultimate function of stigmatization and helping to explain its consensual nature.     

Delivering effective children's services in the community: Reconsidering the benefits of system interventions

This article examines research on systems of care, which are acknowledged as the current dominant paradigm in the delivery of children's mental health services. The authors conclude that systems of care produce important system-level changes. Early results suggest that these systems changes do not impact clinical outcomes, however. One plausible explanation for this finding is that system interventions are too far removed from the actual delivered services, thereby limiting their potential impact. Moreover, numerous assumptions underlying the purported effectiveness of systems of care remain unvalidated. The authors propose that the primary direction to improving children's mental health services should be through effectiveness research, in contrast to continued large-scale investments in systems research and development. Recommendations are made for addressing methodological problems that researchers will confront and for developing policies encouraging future research on the effectiveness of children's mental health services.     

Perception2

The article is an overview of some central philosophical problems associated with perception. It discusses what distinguishes perception from other sensory capacities and from conception. It discusses anti‐individualism, a view according to which the nature of a perceptual state is dependent not just causally but for its identity or ‘essence’ on relations to a normal environment in which systems containing that state were formed. It discusses different views about epistemic warrant. By emphasising the deep ways in which human and animal perceptual systems, especially visual systems, are similar, it criticises a dominant view of the last century, in both philosophy and large parts of psychology, according to which a range of sophisticated supplementary abilities have to be learned before a child can perceive objective features of the physical world.     

Marital systems of agoraphobic women: contributions of husbands' denial and projection

The problems of measuring psychological concepts such as repression and denial are discussed in the context of the marital systems of agoraphobic women and the credibility of a couples approach to treatment. Repression, denial and projection in husbands were inferred from systematic measurement of mood, hostility and symptom changes after intensive behaviour therapy for the agoraphobia. The results suggested that the agoraphobic symptoms of about half of the women were reinforced by their husbands' habitual denial of affect and of personal problems; in this group, worthwhile symptomatic improvement occurred only in those women whose husbands relinquished repression and denial as major defence mechanisms, acknowledging their own personal problems, and allowing the patients to take more responsibility for their agoraphobia. The marital systems of the remaining couples were characterized by incompatible ways of dealing with hostility, with husbands' abnormal extrapunitiveness reinforcing patients' self-blame, which inhibited problem-solving and hence indirectly perpetuated the agoraphobia.     

Category learning and multiple memory systems

Categorization is a vitally important skill that people use every day. Early theories of category learning assumed a single learning system, but recent evidence suggests that human category learning may depend on many of the major memory systems that have been hypothesized by memory researchers. As different memory systems flourish under different conditions, an understanding of how categorization uses available memory systems will improve our understanding of a basic human skill, lead to better insights into the cognitive changes that result from a variety of neurological disorders, and suggest improvements in training procedures for complex categorization tasks.     

Developmental changes in dopamine neurotransmission in adolescence: Behavioral implications and issues in assessment

Adolescence is characterized by increased risk-taking, novelty-seeking, and locomotor activity, all of which suggest a heightened appetitive drive. The neurotransmitter dopamine is typically associated with behavioral activation and heightened forms of appetitive behavior in mammalian species, and this pattern of activation has been described in terms of a neurobehavioral system that underlies incentive-motivated behavior. Adolescence may be a time of elevated activity within this system. This review provides a summary of changes within cortical and subcortical dopaminergic systems that may account for changes in cognition and affect that characterize adolescent behavior. Because there is a dearth of information regarding neurochemical changes in human adolescents, models for assessing links between neurochemical activity and behavior in human adolescents will be described using molecular genetic techniques. Furthermore, we will suggest how these techniques can be combined with other methods such as pharmacology to measure the impact of dopamine activity on behavior and how this relation changes through the lifespan.     

Twenty years of applied behavior analysis in treating the most severe problem behavior: Lessons learned

This paper reviews some of the author's experiences during the past 20 years of treating severe problem behavior. Factors that represent barriers to success are identified and discussed, as are factors that contribute to the development of successful treatment programs. Barriers to success include the inherent reactive nature of human services and educational systems, expertise problems, systems problems, information gaps, programming problems, characteristics of problem behavior, and maintenance problems. Some new programmatic directions are suggested for overcoming the various treatment barriers. The paper concludes with strategies and factors to consider that will ensure long-term success in the treatment of severe problem behavior.     

Human factors in air traffic control: problems at the interfaces

The triangular ISIS model for describing the operation of human factors in complex sociotechnical organisations or systems is applied in this research to a large international air traffic control system. A large sample of senior Air Traffic Controllers were randomly assigned to small focus discussion groups, whose task was to identify problems occurring at the interfaces of the three major human factor components: individual, system impacts, and social. From these discussions, a number of significant interface problems, which could adversely affect the functioning of the Air Traffic Control System, emerged. The majority of these occurred at the Individual-System Impact and Individual-Social interfaces and involved a perceived need for further interface centered training.     

Neurological knowledge and complex behaviors

Some scholars believe thot Cognitive Science is the attempt to achieve in artificial systems what has already been achieved in the brain. Others, by contrast, argue that the study of ideal adaptive mechanisms could go on without reference to the brain. The author points out that the brain may not be the ideal cognitive device because of biological limitotions on its capacity. Although it may not be ideal, it is still of major interest to cognitive scientists because of the great interest in the human mind, and, in addition, because at this moment the brain is the most important single reservoir of odoptive mechanisms. The paper discusses several areas of neuroscience which are likely to shed light on mechanisms of adaptation. The study of simple nervous systems is likely to reveal important design principles of cognitive devices. The study of complex nervous systems will, of course, exert a major influence. The study of such systems leads to certain general principles concerning the neural circuits involved in complex odoptive behaviors: (1) There exist innate specialized systems for the learning of many specific behaviors that at first might appeor to be purely cultural. (2) There is no evidence for the existence of any all-purpose computer in the brain. (3) There are many surprising dissociations manifested by the specialized systems in the brain, e.g., a special system for recognition of faces as against other visual patterns. (4) The study of the nervous system enables one to formulate more precise mechanisms for the role of emotion in cognitive function.(5) Some human behoviors con probably be understood poorly or not at all if the neural substrate is not considered. (6) The cognitive systems designed for dealing with ottentionol processes may be among the most complex neural structures which underlie behavior. There are certain other properties of brains that should be kept in mind by the cognitive scientists who are studying human behovior: (1) Brains differ from each other in structure, and it is very likely that the strategy for the solution of certain problems differs from person to person. (2) The presence of certain innate cognitive strategies in the brain may prevent that organism from employing other strategies which might be optimal for other problems. (3) Any theory about a particular cognitive strategy will have implications as to the particular mode of breakdown that might be expected after brain lesions. The study of disordered function from brain disease may thus be a valuable way to test certain cognitive theories.     

Attention support in digital environments. Nine questions to be addressed

Research in attention aware systems, i.e. systems that support users in their attentional choices, promises to address many of the problems related to information overload, cyber collaboration, and mobility, by providing features helping users in coping with attentional limitations. However, the design of attention aware systems necessitates a deep understanding of human attentional processes, of the knowledge a system needs to support those processes, and of the manner in which such knowledge may be acquired. Because the conceptualization of such systems requires understanding users' cognitive states in terms of their past interactions with the environment, the interactivist framework may provide a strong basis for analyzing attention aware systems.This paper briefly introduces the services that attention aware systems may provide, suggests how attention may be modeled within the interactivist framework, and proposes nine questions that may be answered within such framework to gain the knowledge necessary for the creation of attention aware systems.     

Ordinary magic. Resilience processes in development

The study of resilience in development has overturned many negative assumptions and deficit-focused models about children growing up under the threat of disadvantage and adversity. The most surprising conclusion emerging from studies of these children is the ordinariness of resilience. An examination of converging findings from variable-focused and person-focused investigations of these phenomena suggests that resilience is common and that it usually arises from the normative functions of human adaptational systems, with the greatest threats to human development being those that compromise these protective systems. The conclusion that resilience is made of ordinary rather than extraordinary processes offers a more positive outlook on human development and adaptation, as well as direction for policy and practice aimed at enhancing the development of children at risk for problems and psychopathology.     

Demystifying Intuition: What It Is,What It Does,and How It Does It

Definitions of intuition are discussed and two working definitions are proposed. This is followed by a list of eight unresolved problems concerning intuition. It is suggested that all of these problems can be resolved by cognitive-experiential self-theory (CEST), a dual-process theory of personality according to which people process information with two systems, an experiential/intuitive system that is an associative learning system that humans share with other animals and a uniquely human verbal reasoning system. Intuition is considered to be a subsystem of the experiential/ intuitive system that operates by exactly the same principles and attributes but has narrower boundary conditions. The next section includes a presentation of the most relevant aspects of CEST with an emphasis on the operating rules and attributes of the experiential/intuitive system. This is followed by demonstrating how the operation of the experiential/intuitive system can resolve each of the unresolved problems concerning intuition. The article closes with a comparison of the advantages and disadvantages of the experiential/intuitive and rational/analytic systems. It is concluded that neither system is generally superior to the other, as each has important advantages and disadvantages.     

A Developmental Model for Family Systems

This paper reviews the historical context of concepts of development and some of the problems of applying them to family systems. A model of family systems development is presented that emphasizes changes in family shape through the individual life cycle. Some clinical uses of the model are described.     

Florian Znaniecki: Creative evolution of a sociologist

Znaniecki devoted his creative life to aconstant reexamination of the basic problems of sociology: its subject matter and the methodology through which it can be studied. The developments in his thought can be traced with the help of the prefaces to his books, in which he explains the location of that work in his over-all effort to develop a systematic sociology, the major influences on his thought, and his arguments with other theories. Starting as a philosopher with a special interest in the evolution of values, he spent years as a result of Thomas's influence attempting to find a psychological base for human behavior, finally abandoning the attempt in favor of systems of social interaction. He focused on four such systems: social relation, social role, social groups, and societies.     

The Psychology of Global Environmental Change: Some Basic Data and an Agenda for Cooperative International Research

In the first part of this paper existing evidence (mostly from earth and atmospheric sciences) on global climatic changes and their dependence (and effect) upon human action is briefly reviewed. Reference is made to existing major international programmes of research focusing on these climatic changes. The main part of the paper concentrates on the study of global change within the framework of the social sciences. Five psychological characteristics of global environmental change are explained which would account for the human inability to respond adequately without the supportive means of information presentation and processing. Future research on psychological dimensions of global change should explore these in greater detail and study modes of social communication that will become instrumental in implementing such support systems.

The Ecology of Human-Machine Systems I: Introduction

A symposium entitled, The Ecology of Human-Machine Systems, was held at the Fifth International Conference on Event Perception and Action. This sympo- sium examined the challenges that human-machine systems hold for an ecological approach to perception, cognition, and action and the promises that an ecological approach holds for problems that traditionally have been the domain of human factors psychology. The presenters from this symposium have been invited to submit articles about an applied ecological psychology to Ecological Psychology. Articles that are accepted for publication will be appearing in future issues of this journal. It is hoped that these articles will stimulate productive interaction between ecological and human factors psychology. This correspondence reflects the natural affinity between ecological and human factors psychology. It examines some of the issues that distinguish basic and applied research. It also considers the contribution that ecological physics can make for improving tradi- tional approaches to task analysis. Finally, this article speculates about emerging areas of research in which the ecological approach may contribute to the design of human-machine systems.     

Dynamics of human postural transitions

In the present study, the authors examined transitions between postural coordination modes involved in human stance. The analysis was motivated by dynamical theories of pattern formation, in which coordination modes and transitions between modes are emergent, self-organized properties of the dynamics of animal-environment systems. In 2 experiments, standing participants tracked a moving target with the head. Results are consistent with the hypothesis that changes in body coordination follow typical nonequilibrium phase transitions, exhibiting multistability, bifurcation, critical fluctuations, hysteresis, and critical slowing down. The findings suggest that posture may be organized in terms of dynamical principles and favor the existence of general and common principles governing pattern formation and flexibility in complex systems.
