Ethical Concerns of Nonclinical Forensic Witnesses and Consultants

Current research suggests that nonclinical forensic psychologists[sup1] are appearing increasingly more often in the legal arena. We argue that many of the ethical dilemmas that face these psychologists differ from those encountered by clinical forensic psychologists. To test the accuracy of this assertion, 37 nonclinical forensic psychologists were surveyed to identify some of the ethical issues and dilemmas they have encountered while engaging in expert testimony or pretrial consulting. Respondents were asked also about how they have resolved these ethical issues and whether they were aware of the "Specialty Guidelines for Forensic Psychologists" (Committee on Ethical Guidelines for Forensic Psychologists, 1991). Results of the survey are discussed in terms of the need for additional regulatory guidelines or professional standards that speak directly to the ethical issues confronting nonclinical, forensic expert witnesses and consultants.     

Group Psychotherapy With Ego Impaired Children: The Significance of Peer Group Culture in the Evolution of a Holding Environment

In this paper, we will attempt to delineate the process by which peer group culture emerges and develops among groups of ego impaired children. The process of culture building in groups, as will be illustrated in a detailed case presentation, is critical for the child's development of skills for structuring and ordering the internal and external worlds. By definition, ego impaired children lack the ability to organize their internal experience. The challenge of group treatment with these children is to provide a situation in which their maladaptive efforts to organize volatile affects and impulses can be tolerated and structured. If they are provided with an adequate holding environment, the children learn to create cultural structures (i.e., therapeutic group culture), for the representation of salient aspects of their emotional lives creates the basis for internal organization. Their growing capacity to build integrating structures, at first collectively within the group, (Pfeifer and Weinstock-Savoy, 1984), which previously could only be provided by the therapist functioning as an auxiliary ego.     

The Value of Research Methods in Psychotherapy Research: A Reply to the Commentary of Dr Norton

Norton's commentary on our article has prompted us to think further about the purpose of psychotherapy research. We agree with his suggestion that researchers have much work to do to understand when and for whom interventions are most efficacious. We hope that our field will make progress in this regard. In this reply, we further describe why we believe careful attention to research methods, such as those highlighted in our article, is key to making progress in psychotherapy research.     

How people interpret conditionals: shifts toward the conditional event

We investigated how people interpret conditionals and how stable their interpretation is over a long series of trials. Participants were shown the colored patterns on each side of a 6-sided die and were asked how sure they were that a conditional holds of the side landing upward when the die is randomly thrown. Participants were presented with 71 trials consisting of all combinations of binary dimensions of shape (e.g., circles and squares) and color (e.g., blue and red) painted onto the sides of each die. In 2 experiments (N? = 66, N? = 65), the conditional event was the dominant interpretation, followed by conjunction, and material conditional responses were negligible. In both experiments, the percentage of participants giving a conditional event response increased from around 40% at the beginning of the task to nearly 80% at the end, with most participants shifting from a conjunction interpretation. The shift was moderated by the order of shape and color in each conditional's antecedent and consequent: Participants were more likely to shift if the antecedent referred to a color. In Experiment 2 we collected response times: Conditional event interpretations took longer to process than conjunction interpretations (mean difference = 500 ms). We discuss implications of our results for mental models theory and probabilistic theories of reasoning.     

Personality differences in mental imagery and the effects on verbal memory

This study examined the effects of extraversion and neuroticism on participants’ reported vividness of visual imagery and on their memory performance for concrete and abstract nouns. Groups of extraverts (n = 15) and introverts (n = 15) were selected from a larger original sample and asked to remember a series of concrete and abstract nouns, including a set of lexically ambiguous concrete homonyms (e.g., earth = 1. planet, 2. soil). Extraverts reported more vivid imagery than introverts but this did not translate into better recall for extraverts, even for concrete stimuli. Recall was best for unambiguous concrete nouns, followed by concrete homonyms, then abstract nouns. While initial analyses suggested that there was an interaction between extraversion and the type of word presented, later analyses revealed that neuroticism was the main driver in differences in recall between different word types. While differences in recall were best explained by context availability theory (Schwanenflugel, 1991) rather than dual coding theory (Paivio, 1991), questions remain about the power of either theory to explain the role of individual differences in personality on recall, particularly given that imagery vividness effects were related to extraversion while differences in recall were related to neuroticism. The implications of these findings for future research and theoretical development are discussed.
