The Development of a Clinical Rating Scale the McMaster Model of Family Functioning

This article describes the development and validation of the McMaster Clinical Rating Scale (MCRS). The MCRS is a 7-item scale designed to be completed by a trained rater after completion of an in-depth interview of the family. We present data from four new studies and review previously published articles concerning the reliability, validity, and clinical utility of the MCRS. Adequate interrater reliability and rater stability were obtained. The MCRS was found to correlate significantly with the self-report Family Assessment Device and to discriminate between families in different phases of a depressive disorder.     

The thinking heart: Developmental dynamics in Etty Hillesum'sdiaries

This essay has three purposes. First, it proposes a method for reading texts developmentally, noting the appropriate type of text for this enterprise, the process for estimating the subject's developmental perspective, and necessary cautions when undertaking a developmental interpretation. Second, it highlights developmental dynamics which can be approximated in other contexts. Finally, it lifts up the writings of an extraordinary young Dutch woman, a victim of Auschwitz, offering her life as a model of virtues which our society would do well to imitate more than fifty years after the Holocaust.Where she also directs the Program in Christian Spirituality.     

ON ULTIMATE EPISTEMIC FOUNDATIONS1

This paper is a contribution to the debate on epistemic foundationalism. Section I expounds and criticises Hans Albert's critical rationalist antifoundationalism position. Section I1 discusses Karl-Otto Apel's ‘transcendental pragmatic’ argument for ultimate epistemic foundations. Section III suggests how the latter argument can be restated so as to avoid ambiguity and yield a plausible case for epistemic foundationalism.     

Deceived versus nondeceived participants' perceptions of scientific and applied psychology

Research examining the possible effects of deceptive research participation on participants' perceptions of psychology has yielded equivocal results. The present study's goal was to clarify the possible effects of participation in mildly deceptive research on participants' impressions of scientific and applied psychology. Participants (N = 112) were randomly assigned to one of six experimental conditions: active groups receiving negative, positive, or no feedback, or passive groups receiving negative, positive, or no feedback. Following participation, participants completed measures of impressions of psychotherapy and psychotherapists, researchers, and instructors. The manipulation did not affect attitudes toward psychology on any of the dependent measures, although gender effects resulted on one measure. Participants in general reported very positive attitudes toward the science and practice of psychology. Recommendations are offered for future research on the effects of more extensive deceptions.     

Extraction of relief from visual motion

We quantified the ability of human subjects to discriminate the relative distance of two points from a slanted plane when viewing the projected velocities of this scene (orthographic projection). The relative distance from a plane (called relief) is a 3-D property that is invariant under linear (affine) transformations. As such, relief canin principle be extracted from the instantaneous projected velocity field; a metric representation, which requires the extraction of visual acceleration, is not required. The stimulus consisted of a slanted planeP (specified by three points) and two pointsQ ₁ andQ ₂ that are non-coplanar withP. This configuration of points oscillated rigidly around the vertical axis. We have measured thesystematic error andaccuracy with which human subjects estimate the relative distance of pointsQ ₁ andQ ₂ from planeP as a function of the slant of_P. The systematic error varies with slant: it is low for small slant values, reaches a maximum for medium slant values, and drops again for high slant values. The accuracy covaries with the systematic error and is thus high for small and large slant values and low for medium slant values. These results are successfully modeled by a simple relief-from-motion computation based on local estimates of projected velocities. The data are well predicted by assuming (1) a measurement error in velocity estimation that varies proportionally to velocity (Weber’s law) and (2) an eccentricity-dependent underestimation of velocity.     

Parents, infants, and day-care teachers: Interrelations and implications for better child care

Many young children are reared today in both family and child-care settings. The relation that exists between these two settings has important implications for child care. Bronfenbrenner's (1979) ecological model is used as a way to view the interrelations among children, families, and child-care programs. Data from a study of infants in day care provide information on the time infants spend in family and day-care contexts, how parents and caregivers view children's behavior in these two settings, and rates of otitis media (ear infections) and other illnesses for these children. Results show that infants spend about twice as many hours per day awake with parents as in day care. Regarding child behaviors, parents and caregivers seem to have similar behaviors they like and dislike, but they each see particular children quite differently with respect to these behaviors. Finally, infants in this sample were diagnosed with illnesses 60% to 70% of the time. Findings are discussed in terms of the ecological model with particular attention given to relations between parents and caregivers.     

The dynamics of Prägnanz

Summary There is quite wide-spread agreement about the relevance of pattern Pragnanz (Koffka, 1935) with respect to the human interpretation of visual patterns. There is less agreement about whether pattern Pragnanz is based solely on pattern information (static) or also on the history of the perceiver (dynamic). In Van Leeuwen and Van den Hof (1991), experimental data concerning serial patterns are presented within the framework of the dynamic-network approach initiated by Buffart (1986, 1987). These experimental data are claimed to give evidence against the static-coding approach initiated by Leeuwenberg (1969, 1971). In the present paper, however, I show first that Buffart's theoretical basis is incorrect, and that in fact Leeuwenberg's static-coding approach is the basis for the dynamic-network approach. Second, I show that those experimental data rather give evidence in favor of the static-coding approach, by using those same data for a test of the most recent static-coding model (Van der Helm & Leeuwenberg, 1991; Van der Helm, Van Lier, & Leeuwenberg, 1992). Finally, I propose a reconciliation between the two approaches, in the sense that the dynamic-network model could be shaped in such a way that it yields a simulation, and maybe even an enrichment, of the static-coding model.     

Robust conditioned flavor preferences with a sensory preconditioning procedure

During sensory preconditioning, rats were given two distinct flavors (saccharin and coffee) in sequence with 0, 9, or 27 sec between the two flavors. A control group received the flavors unpaired. In subsequent training, the second flavor preceded sucrose by 5 min. Later, the subjects that had had 0- or 9-sec delays between the two flavors showed a significant preference for the flavor not directly reinforced, whereas those that had had a 27-sec delay showed only a marginally significant preference. Although taste aversions have been produced using these methods, this is the first demonstration of conditioned preferences for flavors not directly associated with the reinforcers. These results offer an alternative way to study flavor-flavor learning.     

Reliability of self-reported service use: Test-retest consistency of children's responses to the Child and Adolescent Services Assessment (CASA)

This paper reports on the reliability of children's responses on the Child and Adolescent Services Assessment (CASA) — a self-report instrument for use with 8– to 18-year-olds that gathers information about services used to address mental health problems. Findings were based on interviews completed by 77 children at a one week test-retest interval. Results showed that reports of lifetime service use were as reliable as were reports of service use in the preceding three months. Children reported restrictive and intrusive services more reliably than services that were provided in their natural environment. Reliability appeared to be associated more strongly with characteristics of the type of service than with characteristics of the child. Children also could report reliably on some details about their encounters with service providers (e.g., length of stay, number of visits, and onset of service use).
