System-Wide versus Component-Specific Trust Using Multiple Aids

Previous research in operator trust toward automated aids has focused primarily on single aids. The current study focuses on how operator trust is affected by the presence of multiple aids. Two competing theories of multiple-trust are presented. A component-specific trust theory predicts that operators will differentially place their trust in automated aids that vary in reliability. A system-wide trust theory predicts that operators will treat multiple imperfect aids as one “system” and merge their trust across aids despite differences in the aids’ reliability. A simulated flight task was used to test these theories, whereby operators performed a pursuit tracking task while concurrently monitoring multiple system gauges that were augmented with perfect or imperfect automated aids. The data revealed that a system-wide trust theory best predicted the data; operators merged their trust across both aids, behaving toward a perfectly reliable aid in the same manner as they did towards unreliable aids.     

An Evolutionary Approach Toward Exploring Altered States of Consciousness,Mind–Body Techniques,and Non-Local Mind

Humans are a part of the complex system including both natural and cultural-technological environment. Evolution of this system included self-amplifying feedbacks that lead to the appearance of human conscious mind. We describe the current state of the understanding of human brain evolution that stresses neurohormonal and biochemical changes rather than simple increase of anatomical substrate for the mind. It follows that human brain is strongly influenced by the state of the body and may operate at various levels of consciousness depending on its biochemical environment created by ingestion of various substances and by specific physical activities. Through the study of the widespread phenomenon of shamanism that uses mind-altering practices we argue that altered states of consciousness and non-local minds are not only real phenomena, but that they are products of natural evolution, valuable for human survival and development. Consideration of altered states of consciousness and broadening of the framework for understanding brain function beyond mechanistic interpretations is necessary to further develop human adaptations and provide a better way of fitting humans as parts of the interconnected system into the global and universal patterns.     

Factors influencing child witnesses

This study elucidates how professional intervention can influence children's abilities to report accurately about abuse experiences. Based on knowledge acquired through previous research and the present case study, the study shows how methods of information acquisition used during preliminary investigations can negatively affect child reports. The case study emanates from a larger study of 193 allegedly sexually abused children. Examination of these police interviews shows that 55 children were interviewed more than once and their reports were exposed to possible professional influences before and during the preliminary investigation. The case study reveals the inadequate management of a child witness. The findings indicate that police officers and psychologists should avoid suggestive interventions and co-ordinate their efforts during the preliminary investigation in order to safeguard the children's as well as the suspects' legal interests. This paper points out the need for implementing interview interventions that can enhance children's abilities to report accurately about abuse experiences.     

Anxiety Disorders in Childhood: Casting a Nomological Net

Empirical research highlights the need for improving the childhood anxiety disorder diagnostic classification system. In particular, inconsistencies in the stability estimates of childhood anxiety disorders and high rates of comorbidity call into the question the utility of the current DSM criteria. This paper makes a case for utilizing a nomological net⁴ model for advancing the understanding of childhood anxiety disorders. In this article, we discuss measurement and assessment issues related to improving the childhood anxiety disorder diagnostic system and show how these issues can be addressed by employing the nomological net of childhood anxiety. Because employing the nomological net involves drawing from etiological process theories to facilitate classification and assessment, an integrative model of childhood anxiety disorders is presented as a tentative heuristic. Then evidence for the existing symptom sets is discussed in the context of how process theory mechanisms may be utilized to improve classification and assessment. Testable hypotheses are presented. Measurement, disorder definition, treatment, and policy implications are also discussed.A nomological net can be briefly defined as the theoretical structure of a construct.

The role of contextual variables in maternal reactions to children's compliance and noncompliance

The present study was designed to assess whether certain contexts influenced material reactions to children's compliant and noncompliant behavior. Study 1 examined the following contextual variables: chronic negative conditions of the child (physical illness and psychological disturbance) and recent life events experienced by the child (both positive and negative). Study 2 examined maternal mood states as another contextual variable. Results indicated that these contexts relate to differential choices of discipline techniques, based on maternal self-report. These data are examined in light of the literature on treatment acceptability and are discussed in terms of a signal-detection model. Clinical applications are addressed, and suggestions for future research are offered.Portions of this paper were presented at the meeting of the Association for Advancement of Behavior Therapy, Philadelphia, November 1984.We express gratitude to the Research Council of the University of North Carolina at Greensboro for Research Council Grant 2110 218 00000 7719 and to the following for their assistance: James Herbert, Nancy Quinn, Carol Roberson, Ira Turkat, and Marilyn Williams.     

A minimum-cost network-flow solution to the case V thurstone scaling problem

This paper presents an approach for determining unidimensional scale estimates that are relatively insensitive to limited inconsistencies in paired comparisons data. The solution procedure, shown to be a minimum-cost network-flow problem, is presented in conjunction with a sensitivity diagnostic that assesses the influence of a single pairwise comparison on traditional Thurstone (ordinary least squares) scale estimates. When the diagnostic indicates some source of distortion in the data, the network technique appears to be more successful than Thurstone scaling in preserving the interval scale properties of the estimates.My special thanks go to Alvin Silk, Thomas Magnanti, and Roy Welsch for their support and advice throughout the formative stages of this paper, and to V. Srinivasan for his helpful comments on a later draft of this paper. I also wish to thank the Editor, Associate Editor, and two reviewers for their constructive suggestions.James M.

AN EXPERIMENTAL ANALYSIS OF “SPILLOVER” EFFECTS ON THE SOCIAL INTERACTION OF BEHAVIORALLY HANDICAPPED PRESCHOOL CHILDRENsp1

The effects of prompting and social reinforcement directed to target subjects on their social behavior and that of peers who never received prompting and reinforcement for positive social behavior, were examined. In a combined reversal and multiple-baseline design, three behaviorally handicapped preschool boys who exhibited divergent social behavior repertoires and varied histories with social reinforcement events, were sequentially exposed to intervention conditions in order to investigate “spillover” of treatment effects. Prompting and reinforcement increased positive social behavior and decreased negative social behavior emitted by all target subjects. The results also demonstrated a “spillover” effect on two target subjects, who at various times were not under intervention, and on the peers as well. The findings suggest that: (a) the direct and indirect effects of intervention procedures may be enhanced by designing treatment based on the social repertoire and reinforcement histories of the subjects; and (b) the treatment “spillover” effect may be increased by applying procedures to two children at once, rather than to one at a time.     

Experiential Family Therapy: An Innovative Approach to the Resolution of Family Conflict in Genetic Counseling

Experiential family therapy is an intuitive approach that utilizes active, multisensory techniques. These techniques, such as role plays and drawings, increase the family's expression of affect and uncover new information. Increased affect and uncovered information stimulate change and growth in the family system. Experiential techniques are especially useful when more traditional, verbal-based communication is not effective. In this article, I will present a pediatric case in which the patient, a 7-year-old boy diagnosed with autism, was referred to the genetics clinic to rule out the presence of an associated genetic disorder. I will then describe a hypothetical second counseling session with the same family and suggest how three experiential family therapy techniques: family drawing, empty chair technique, and continuums might be used in the session to help resolve a marital conflict between the patient's parents.     

Competing Conceptions of Diagnostic Reasoning – Is There a Way Out?

Diagnostic errors are more frequently a result of the clinician's failure to combine medical knowledge adequately than of data inaccuracy. Diagnostic reasoning studies are valuable to understand and improve diagnostic reasoning. However, most diagnostic reasoning studies are characterized by some limitations which make these studies seem more simple than diagnostic reasoning in real life situations actually is. These limitations are connected both to the failure to acknowledge components of knowledge used in clinical practice as well as to acknowledge the physician-patient relationship's influence on clinical knowledge and on the reasoning process itself. In addition the modes of reasoning described in these studies frequently is oversimplified. In this paper three simplistic and competing models of diagnostic reasoning are analyzed and criticized, followed by an evaluation of two alternative models proposing a combined view.
