Interpersonal relations: Cooperation and competition

Social relations between two persons require that consequences each receives depend at least in part on the responses of the other. Historically, research in several areas has focused on two contingencies, cooperation and competition, in which reinforcement is determined by the responses of both participants. A major research question in social psychology and applied behavior analysis has been: Which contingency is more effective with regard to the quantity or quality of some response? Although this question has not been addressed in the experimental analysis of behavior, this area provides a perspective and method to more fully investigate the relevant controlling variables. Among these are the frequency of opportunities to audit the performances of others, information (or lack of it) provided by social or nonsocial stimuli with regard to reinforcement and performance, degree of face-to-face interaction, types of reinforcement contingencies, and number of participants. A neglected dependent variable is cost effectiveness — amount of behavior maintained by a given reinforcer amount. The larger agenda for the experimental analysis of interpersonal relations includes a variety of forms of reinforcement interdependence that raise issues of basic and applied interest.     

Alcohol,head injury,and neuropsychological function

Evidence is reviewed indicating that the extent of alcohol abuse alone cannot account for the neuropsychological deficits observed in alcoholics, and that alcohol abuse and head injury may interact in some patients to influence neuropsychological status. Alcohol abuse both increases the risk for head trauma and potentiates the resulting brain injury, which can lead to negative neuropsychological consequences. Clinicians involved in the treatment of addiction should assess patients for history of head injury, and neuropsychological deficits consequent to both head injury and ethanol. These deficits may limit patient ability to comply with addiction rehabilitation programs. Conversely, clinicians in acute care and rehabilitation of the sequelae of head trauma should routinely assess their patients for substance abuse, because such abuse can have a significant impact on recovery from brain injury.     

Assessment of fear of fear among Agoraphobic patients: The Agoraphobic Cognitions Scale

A self-report scale for the measurement of fear of fear, the Agoraphobic Cognitions Scale (ACS), was psychometrically evaluated. Two samples of inpatients satisfying DSM-III-R criteria for unipolar depressive and/or anxiety disorder were studied. Intercorrelational and factor analyses indicated that the ACS measured three dimensions of fear of fear: fear of bodily incapacitation, fear of losing control, and fear of acting embarrassingly. Three subscales were constructed to measure these dimensions. The subscales proved to have satisfactory internal consistency and criterion-related validity. However, fear of losing control was related not only to other anxiety symptoms, but also to depressive symptomatology. Agoraphobic patients reported more fear of bodily incapacitation and fear of losing control than social phobic, generally anxious, and nonanxious depressed patients. Fear of embarrassing action was higher among agoraphobic and social phobic patients than among generally anxious and nonanxious depressed patients. These results were obtained after controlling for general anxiety and depression level and, thus, support the validity of the fear of fear construct.     

Who's Up First? Testing for Order Effects in Structured Interviews Using a Counterbalanced Experimental Design

A growing body of research suggests that, apart from the wording of specific questions, various aspects of the interview process itself may affect the reliability of information provided by research participants. To examine whether the order of presentation of specific diagnostic modules affects the likelihood of subjects' yes/no responses within the Diagnostic Interview Schedule for Children (DISC), the authors used a counterbalanced design, presenting two DISC diagnostic modules to children and their parents in standard or reversed order. Results indicate that the order of module administration exerts effects on the total numbers of symptoms endorsed, level of impairment, and the likelihood of meeting diagnostic criteria, regardless of whether the information is provided by parent or child respondents. Future child and adult assessment measures should take these difficulties fully into account through novel approaches to instrument design and interview procedures.     

Subject and Interview Characteristics Affecting Reliability of the Diagnostic Interview Schedule for Children

Despite the well-known difficulties in obtaining reliable and valid assessments of child psychopathology, investigators generally have not examined the influence of factors such as subject characteristics or the specific assessment procedures themselves on the validity of the information obtained. To address these issues, this special section presents four studies of the Diagnostic Interview Schedule for Children, in which investigators examined the impact of a range of variables on the reliability of its symptom and diagnostic information. Factors studied include interview structural characteristics; question length, complexity, and placement within the interview; and interview subject characteristics. Overall findings suggest that interview and subject characteristics exert important influences on the data obtained, and that novel approaches, such as allowing subjects a greater role in the ordering of questions to be answered, may improve the precision and accuracy of such measures of children's psychopathology.     

Spider-Phobic Children Do Not React with Differential Skin Conductance Responses to Masked Phobic Stimuli

In the present study, spider-phobic children (N = 22) were exposed to subliminal presentations of spiders, snakes, and mushrooms, while skin conductance responses (SCRs) were measured. In addition, pre- and post-treatment symptom severity data were obtained. As a group, spider-phobic children did not react with differential SCRs to masked phobic pictures. In addition, no convincing evidence was found to suggest that individual variation in differential SCRs to phobic stimuli is linked to pre-treatment symptom severity or therapy outcome. These findings cast doubts on the idea that phobics' phenomenal experience of their fear as irrational and uncontrollable is a result of pre-attentive physiological fear activation.     

Custody and Access Evaluations: Issues for Mental Health Professionals Conducting Assessments withMentally Disordered or Mentally Retarded Parents

Mental health professionals are increasingly beingcalled upon by the courts to offer their expertise inchild custody and access disputes. This paperaddresses the specialized role mental healthprofessionals have in custody and access hearings,particularly in cases wherein one or both parents havereceived a mental diagnosis (i.e., of mental disorderor mental retardation). The focus upon thispopulation of parents is warranted, as there is adearth of both empirical literature and professionalguidelines to provide direction to the mental healthprofessional that is offering his or her expertise tothe court regarding these parents. Additionally,there are specific issues that the mental healthprofessional needs to remain cognizant of, above andbeyond general issues associated with conductingcustody and access assessments, when conductingassessments on parents with mental diagnoses. Theliterature on the parenting behaviors and risk ofchild abuse and neglect associated with mentallydisordered and mentally retarded parents is reviewed,and the limitations in our empirical knowledge ofthese areas are highlighted. Recommendations formental health professionals conducting custodyevaluations in hearings where one or both parents havea mental diagnosis are provided.     

Cognitive Event-Related Potentials in Neuropsychological Assessment

Neuropsychology is a behavioral approach to studying the brain, and an integration of neuropsychology with on-line processing measures of brain function is important for advancing the understanding of brain–behavior relationships. Cognitive event-related potentials (ERPs) are on-line processing measures that are of interest to neuropsychologists because they are linked to familiar neuropsychological test paradigms and because they have reached a degree of standardization sufficient to make them applicable in individual assessment. A selective review of cognitive ERPs is given, focusing on studies of attention in the oddball paradigm and arguing that an adequate assessment of attention is basic in understanding higher order cognitive functions. General principles for using ERP data to supplement and clarify neuropsychological analysis are discussed, and available evidence on dementia and traumatic head injury is reviewed. It is concluded that ERPs are a useful supplement to neuropsychological assessment. Although diagnostic use of ERPs must be guarded because of limited standardization and validation, information-processing analysis with ERPs may aid significantly in interpretation of behavioral data.
