Assessing the Truthfulness of Witness Statements Made by Children (Aged 7--8, 10--11, and 13--14) Employing Scales Derived from Johnson and Raye's Model of Reality Monitoring

The goal of this study was to determine whether children's true and false witness statements could be differentiated using the model of reality monitoring. The effects of age and verbal ability on scales based on the model were also investigated. Children (N = 68) from three different age-groups (7--8, 10--11, and 13--14 years) made both a true and a false statement concerning a mildly traumatic event. The statements were analysed using the Revised Memory Characteristics Questionnaire. The vocabulary sub-scale of the WISC-R was also administered. True statements were found to contain more sensory information and expressions of time, and less affective information. Overall, 64% of the statements were correctly classified on the basis of the scales. Older children received higher scores on most of the reality monitoring scales compared to the youngest children regardless of the truthfulness of their statements. Furthermore, the verbal ability of the children was positively associated with scores on several of the scales. The classification accuracy suggests that the model should not be applied to individual cases of child testimony. Although the final decision concerning the usefulness of the scales should be based on ecologically valid field studies.     

ON THE RELATION OF MANDS AND THE FUNCTION OF DESTRUCTIVE BEHAVIOR

When standard analogue functional analysis procedures produce inconclusive results in children with conversational speech, the child's mands may help to identify the function of destructive behavior. In the current investigation, functional analyses conducted with 2 children who exhibited self-injury, aggression, and property destruction were undifferentiated across conditions. Based on informal observations and school and parental report, an analysis was conducted using mands to help determine the function of the destructive behavior. Using a multielement design, the therapist's compliance with the child's mands occurred either on a fixed-ratio (FR) 1 schedule or contingent on destructive behavior. Destructive behavior occurred at high and consistent levels when reinforcement of mands was contingent on destructive behavior and at near-zero levels when reinforcement of mands occurred on the FR 1 schedule. Based on these results, a second analysis was conducted in which compliance to mands occurred only when the child appropriately requested it (i.e., functional communication training plus extinction) and, for 1 child, compliance with mands was terminated contingent upon destructive behavior (i.e., functional communication training plus response cost). For both children, the rates of destructive behavior decreased markedly. The results suggest that assessing the child's mands may be useful in decreasing destructive behavior when a functional analysis is inconclusive.     

Negotiating the Reality of Visual Impairment: Hope, Coping, and Functional Ability

A consecutive sample of 63 adventitiously blinded American military veterans in a interdisciplinary inpatient rehabilitation program participated in this study examining the relation of hope to self-reported functional ability level. Scores from a modified oral administration of the Hope Scale and the Millon Behavioral Health Inventory basic coping styles were used as predictor variables to test regression-based models of mediation and moderation relations to functional ability level. Results support a mediating role for hope in the relation between a proactive sociable style and perceived level of functional ability.

Recent reinforcement-schedule research and applied behavior analysis

Reinforcement schedules are considered in relation to applied behavior analysis by examining several recent laboratory experiments with humans and other animals. The experiments are drawn from three areas of contemporary schedule research: behavioral history effects on schedule performance, the role of instructions in schedule performance of humans, and dynamic schedules of reinforcement. All of the experiments are discussed in relation to the role of behavioral history in current schedule performance. The paper concludes by extracting from the experiments some more general issues concerning reinforcement schedules in applied research and practice.     

Newborns of mothers with depressive symptoms are less expressive

The facial expressions of 40 newborns of mothers with depressive symptoms (n = 20) and of nondepressive mothers (n = 20) were recorded during the Brazelton Neonatal Behavior Assessment Scale and during the modeling of happy, sad, and surprised faces. Infants of mothers with depressive symptoms demonstrated inferior performance on the orientation cluster of the Brazelton scale and showed fewer interest and more precry expressions during the Brazelton. During the facial expression modeling, they showed less orientation and fewer facial expressions in response to the modeled happy and surprise facial expressions.     

Cognitive ability and communicative disability

The area of cognitive ability and communicative disability is introduced and delineated in this special issue of Scandinavian Journal of Psychology. A set of 13 chapters is included in the issue to illustrate the theoretical and methodological advances in the areas of memory and amnesia, reading and dyslexia, speech-reading, tactile speech and objects, and developmental disorders. Theoretical communalities among the different subspecialities are emphasized.     

The Development of Early Externalizing Problems Among Children from Low-Income Families: A Transformational Perspective

The present study examined pathways leading to early externalizing problems from age 1 to 31/2 in a design that took advantage of our knowledge of normative progression and normative socialization as well as findings from research on risk. A sample of 130 low-income participants was followed longitudinally from 12 to 42 months using observational measures of developmentally salient parenting and child disruptive behavior to predict early externalizing problems. Results are best accommodated by concepts such as transformation and transaction from developmental psychology. For boys, both child and parent variables predicted later externalizing. For girls and boys, the interaction between child noncompliance and maternal rejection was significant.     

Relations between infant irritability and maternal responsiveness in low-income families

Relations between infant irritability and maternal responsiveness at 12 and18 months were investigated in low-income mother-infant dyads. Emphasis was placed on whether results varied according to measurement strategies, infant gender, or level of maternal social support and satisfaction with that support. Irritability was measured separately through observation and maternal report, responsiveness was measured observationally, and maternal social support and satisfaction were self-reported via questionnaire. Concurrent relations between irritability and responsiveness were, in general, negative and were larger when irritability was measured observationally rather than by maternal report. Correlations were similar across gender. No longitudinal relations were found between irritability and responsiveness. Amount of maternal social support was weakly related to responsiveness and to responses to infant irritability, and the nature of these relations was unexpected. Irritability-responsiveness relations varied as a function of measurement strategies, which may in part explain mixed findings in the empirical literature.     

The rasch model,the law of comparative judgment and additive conjoint measurement

Relationships between the Rasch model and both the law of comparative judgment and additive conjoint measurement are discussed. The distance between the ability of Persona and the difficult of Itemi is, in the Rasch model, the baseline value corresponding to the probability thata will respond correctly toi, where this probability is interpreted as the area under a logistic curve (which is substantially equivalent to the normal curve) and is thus an application of the law of comparative judgment. Under certain assumptions, the Rasch model is also a special case of additive conjoint measurement and, properly reinterpreted, may be usefully applied in contexts other than individual differences.
