PIGEONS ARE SENSITIVE TO THE SPATIAL ORGANIZATION OF COMPLEX VISUAL STIMULI

Abstract— Two experiments investigated the role of spatial organisation in the discrimination and generalization of complex visual stimuli by pigeons. In Experiment 1, after pigeons had been trained to discriminate line drawings of four objects, they were tested with novel pictures in which the same component parts of the objects were spatially rearranged. The spatially scrambled pictures led to a dramatic drop in recognition accuracy, hut responding remained above chance. In Experiment 2, pigeons reached a high level of discriminative performance when required to choose among four different spatial arrangements of the same object parts. These results confirm Cerella's (1980) conclusion that pigeons discriminate the component parts of complex visual stimuli, but. unless it is assumed that the scrambling deleted or created emergent features, the results disconfirm his conclusion that spatial organization plays no role in pigeons' picture perception.     

Person-centered theory and the contemporary practice of psychological testing

This paper examines the effects of person-centered theory on contemporary psychological testing. Seven basic ideas or assumptions, which are integral to and guide the testing process, are identified and briefly discussed. Each idea is considered to have been affected either directly or indirectly by person-centered philosophy. Some of the ways in which these ideas are reflected in contemporary testing practice are indicated.     

Creativity and Aging: Personal Journals and the Creation of Self

This article considers the writing of personal journals as a process through which an individual constructs a linguistic representation of one's self, with the self constituting a narrative. Rather than a fixed narrative, one's life exists as a narrative subject to revision and reinterpretation. Through journal writing, then, one constructs and reconstructs his or her identity. Berman finds the value in personal journals not only in the themes that surface but also in the creative process they reveal. In this article, he examines passages from five journalists that demonstrate this process of creating and revising meaning in one's life.

Authoritarianism and Economic Threat: Implications for Political Behavior

This study examined whether authoritarians experiencing economic threat are more likely than other authoritarians to support social policy and political agendas that restrict benefits or curtail rights for disadvantaged groups. A sample of 131 college students completed questionnaires that measured authoritarianism, degree of economic and societal insecurity, and attitudes toward eight political issues. Economic and social insecurity were indexed to perceptions of whether one's standard of livingg had declined, whether incom inequality had grown among social classes, and whether crime, race relations, environmental quality, and governmental services had worsened. The political scales reflected issues currently debated in public forums; they included funding mechanisms for social security and health care, the state's role in regulating abortion, government services for illegal immigrants, terminating welfare for unemployed women with children, and regulation of sexual conduct. A logistic model found that, relative to non-threatened authoritarians or nonauthoritarians, threatened authoritarians were six times as likely to favor restricting benefits to powerless groups and eight times as likely to support the state's preventing women from securing anabortion. These results are discussed in terms of systemic changes in the economy that have resulted in declines in real income and increasing income inequality.     

Case illustration: Moving along…and,is change gradual or sudden?

A sequence of analytic sessions of a professional woman in her forties is used to illustrate the moving along process. The material shows a gradual change, where the patient's experience of her sense of agency is altered through a particular kind of interactive sequence. The example is intended to make it clear that the group's view of how change occurs is not strictly or primarily in terms of sudden changes, and that the problem of assessing moments of meeting as well as quantitative and qualitative shifts is one with which the group continues to struggle. © 1998 Michigan Association for Infant Mental Health     

Writers Blocked: On the Wrongs of Research Co-authorship and Some Possible Strategies for Improvement

The various problems associated with co-authorship of research articles have attracted much attention in recent years. We believe that this (hopefully) growing awareness is a very welcome development. However, we will argue that the particular and increasing importance of authorship and the harmful implications of current practices of research authorship for junior researchers have not been emphasised enough. We will use the case of our own research area (bioethics) to illustrate some of the pitfalls of current publishing practices—in particular, the impact on the evaluation of one’s work in the area of employment or funding. Even where there are explicit guidelines, they are often disregarded. This disregard, which is often exemplified through the inflation of co-authorship in some research areas, may seem benign to some of us; but it is not. Attribution of co-authorship for reasons other than merit in relation to the publication misrepresents the work towards that publication, and generates unfair competition. We make a case for increasing awareness, for transparency and for more explicit guidelines and regulation of research co-authorship within and across research areas. We examine some of the most sensitive areas of concern and their implications for researchers, particularly junior ones, and we suggest several strategies for future action.     

Could Presentism in the Histories of Psychology Actually be Futuristic?

Disputes about the origins of psychology in the history of the discipline are functional not for our understanding of the past, but as normative signs that regulate the construction of ideas in the future. We introduce the notion of open-ended normativity that regulates the development of a given discipline towards its future. Hence the question of the cultural origins of psychology becomes contested in the 21st century as an important topic. It proves that the history of psychology is an active participant in the making of psychology, as it is creating its future.     

Implicit Theories of Common Health Conditions Held by Indian Social Workers and Students

Social work is viewed as a change-related profession. However, little is known about social workers’ own beliefs about change. To understand this, we used the implicit theory paradigm to compare theories about various health conditions held by social workers, social work students, and undergraduate students from Bombay, India (N = 352). The participants had to assess the possibility of change in four health conditions: cancer, tuberculosis, depression, and mental retardation. We predicted that social workers whose professional education involves concepts such as Person-in-Environment would display more incremental views of these conditions than students – namely that they are modifiable. Our predictions were supported for the following conditions: cancer, tuberculosis, and depression. These incremental views were neither related to age nor years of professional experience. Though we expected that the extent to which participants believed these health issues to be amenable to change would influence their support for a small personal tax, our findings did not bear this out. We explore the possible reasons for our findings and discuss their implications for health communication in India as well as for social work education.
