The effects of stimulus sequence on event related potentials: A comparison of visual and auditory sequences

The effect of stimulus sequence on the waveform of the scalp-recorded event-related potential (ERP) was studied in the auditory and visual modalities. The results indicate that the sequential effects are qualitatively similar in the two modalities; however, an interaction appeared between the modalities and the stimulus effects. The degree of sequential effect was a function of whether or not the stimulus eliciting the ERP was the counted (target) event. This finding is discussed in terms of an expectancy model, and the interaction is attributed to variations in short-term memory for past events as a function of the level of processing required for each.     

The perception of assimilation and brightness contrast as derived from code theory

It is shown that assimilation and brightness contrast effects are evoked by structural aspects of patterns. In a pilot experiment, variously shaped gray patterns were used as stimuli. The backgrounds used with each of these shapes were identical: half black and half white. If the gray area against the black part was judged to be more black than the gray area against the white part, an assimilation effect will have occurred; when the reverse occurred, this was called a contrast effect. The task was to rank-order the stimuli on the assimilation-contrast scale. It is argued that the two effects are due to two different interpretations, each derivable from a different code of a pattern. The simpler the contrast code is with respect to the assimilation code, the more it will be perceptually preferred. In the specification of pattern complexity, structural information theory was used. A significant correlation was discovered between the theoretical preference for the contrast interpretation and the contrast preference of subjects.     

How residents cope with living near a hazardous waste landfill: An example of substantive theorizing

It is hard to be a community or environmental psychologist and not be interested in newspaper stories on global warming, oil spills, or toxic wastes in your own backyard. To the general public, these issues tend to be viewed as environmental, technological, toxicological, or governmental, but not psychological. As psychologists, we see many ways in which psychology does play a role in understanding these events. We have been engaged in a study of residents living near a hazardous waste landfill in which many subdisciplines of psychology have played an illuminating role. Wicker's (this issue) article on substantive theorizing outlines an approach to theory and research that helps communicate the structure and process of doing research on a complex area. We use his article to help us describe key aspects of our research that are not usually discussed in research articles. We believe that the type of research Wicker describes occurs more often than people realize. Unfortunately, however, journal conventions cause investigators to omit discussions of substantive theorizing aspects of their work. We hope that reading this article increases your understanding of substantive theorizing and our research as much as writing it increased our own.     

Trauma, Shame, and Group Psychotherapy: A Self Psychology Perspective

This paper attempts to define trauma from a self psychology/intersubjective perspective and explores shame as a basic aspect of trauma. Self psychologically oriented group therapy is examined as an effective treatment modality for dealing with issues of shame as well as the after effects of trauma.     

Differentiation of personality types among opiate addicts

A wide range of studies indicate that although sociopathic characteristics are predominant in opiate addiction, depressive and psychotic features are also frequently observed. To test the hypothesis that there are really three types of individuals who become addicted to opiates (rather than a single, predominant personality style), fifty-three opiate addicts were given the Loevinger Sentence Completion Test, the Bellak Ego Functions Interview, and the Rorschach. Variables derived from these three procedures were submitted to cluster and discriminant function analyses. Three groups of addicts were identified--those primarily with impaired interpersonal relationships and affective lability (42%), those primarily characterized by thought disorder and impaired ego functioning (30%), and a group with diminished ideational and verbal activity (28%). Comparison of the assessment of these three groups with independently defined normal, neurotic, and schizophrenic samples provided support for three opiate-addicted personality types, each respectively characterized as character disordered, borderline psychotic, and depressed. Although there seems to be a predominance of character-disordered individuals who become addicted to opiates, the data indicate several additional types of opiate addicts with different types of psychopathology who may require different approaches to management and treatment.     

Pilot test of a measure to assess clients’ perceptions of their home visitors

Home visiting services for caregivers of infants and young children have been found to be an effective method for promoting child development. Unfortunately, such services suffer from high rates of attrition, suggesting the need to identify factors related to client retention in services. Research has indicated that the client-provider relationship is an important predictor of client retention in home visiting services; however, measures to assess this relationship are limited. This study reports on a pilot test of the Client Perceptions of Home Visitors Questionnaire, developed to assess home visiting clients’ perceptions of their relationship with their home visitor. The measure was completed by 39 diverse home visiting clients during pregnancy in a midwestern town in the United States. The scale was found to have good internal consistency. Validity analyses found that the scale was positively associated with client satisfaction with services and perceived provider cultural sensitivity. The scale was also positively associated with retention in services at an 8-month follow-up. Additional research should examine the measure's psychometrics with larger samples.     

Merleau‐Ponty and Nagarjuna: relational social ontology and the ground of ethics

Through a comparative analysis of the key ontological notions in Merleau‐Ponty and Nagarjuna, I develop a relational social ontology that is grounded in their respective implicit and explicit ethics. Both thinkers take heed of our being‐in‐the‐world; this is evident in their views on intersubjective sociality and language. Recognizing the limitations in these views points us toward a greater understanding of the meaningfulness of our situated existences. In this vein, I propose a number of ideas to guide the work of comparative philosophy.     

Are Some Psychotherapies Much More Effective Than Others?

In a previous paper we had reported on the examination of comparisons of 18 metaanalyses of active treatments with each other (Luborsky, Rosenthal, Diguer, et al., 2001). These metaanalyses gave a small and nonsignificant mean level of difference between types of treatments. The smallness of this correlation confirms Rosenzweig's (1936) expectation that because of the large overlap in effective ingredients of different psychotherapies, comparative studies of psychotherapies would show little difference. Such a comparison that includes psychoanalyses seems a long way off, but if outcomes of psychoanalyses are defined similarly to those in the other psychotherapies, the expected differences in outcomes may also be small.
