Transformation to achieve a longitudinally stationary factor pattern matrix

Meredith's method of extracting a factorially invariant solution is adapted to longitudinal settings. An explorational estimation procedure is presented which attempts to identify the longitudinal factor components of an across occasion variance-covariance matrix. This is effected by transforming an initial factor pattern matrix to stationarity. The estimation is performed in two parts, the first employing a stepwise algorithm to ascertain the dimensionality and existence of the longitudinal components and the second being the direct estimation of the existing factor pattern.     

Out of the laboratory and into the community. 26 years of applied behavior analysis at the Juniper Gardens Children's Project.

Application of Skinner's principles to socially significant human behavior had been well articulated by 1968 (Baer, Wolf, & Risley, 1968). Applications of these principles by Baer, Wolf, Risley, Hall, Hart, Christophersen, and their colleagues were in evidence as early as 1964 in the homes, schools, and clinics of inner-city Kansas City, Kansas, at the Juniper Gardens Housing Project. The work continues relatively uninterrupted, having contributed extensively to the literature of applied behavior analysis and the lives of community residents. This article describes the project and illustrates how applied behavioral research was initiated and extended, how the work addressed general concerns in psychology, and how it continues to address contemporary concerns within the community.     

THE CLASSWIDE PEER TUTORING PROGRAM: IMPLEMENTATION FACTORS MODERATING STUDENTS' ACHIEVEMENT

We conducted a study designed to assess implementation of the classwide peer tutoring program and the relationship between implementation variation and student outcome. A clinical replication design was used. Five volunteer elementary teachers were trained to implement the program; their implementation was monitored for 19 consecutive weeks during 1 school year. Overall, the results indicated that specific variations in program implementation were associated with students' responses to treatment. It was also demonstrated that different teachers' applications of the program produced differential levels of student outcome. Implementation factors related to lower spelling achievement were (a) reduced opportunities to receive program sessions, (b) reduced probabilities of students' participation in program opportunities, (c) too many students assigned unchallenging spelling words, and (d) reduced rates of daily point earning reflecting lower levels of spelling practice during tutoring sessions. The implications of these findings and methods of preventing these implementation problems are discussed in the context of quality assurance and social validity.     

The California Family Health Project: IV. Family structure/organization and adult health.

This research explores the relationships between each of four "domains" of family life and the health of husbands and wives in a community-based sample of 225 families. In this article we report the association between Family Structure/Organization and adult Health. This family domain refers to the architecture of the family or the structural frame of roles and rules within which the family operates. Interrelationships among 13 self-reported, family Structure/Organization scales are described, using principle components analysis (PCA) and multidimensional scaling analysis (MDS). Derived, joint-spouse or couple Structure/Organization variables also were created using inter-battery factor analysis. The PCA yielded a poor solution, whereas the MDS yielded a good two-dimensional solution, which roughly displayed the scales in a circular pattern for both husbands and wives. The analyses indicated that no single dimension or set of separate subdimensions adequately described the Structure/Organization variables. All 13 scales than were associated with a battery of 14 adult health scales for husbands and wives separately, using canonical correlation. Different aspects of family Structure/Organization were correlated with health for husbands and wives: Organized Cohesiveness, Sex Role Traditionalism, Role Flexibility and Shared Roles for husbands; and Organized Cohesiveness and Differentiated Sharing for wives. Different patterns of health scores also emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: II. Family world view and adult health.

This article explores the pattern of relationships between family World View and adult Health in a community-based sample of 225 families. Family World View refers to the beliefs, appraisals, and values that define a family's orientation to the world. The interrelationships among eight self-reported family World View variables are described, using principal components analyses (PCA) and multidimensional scaling analyses (MDS). Derived, joint-spouse World Views also are examined using inter-battery factor analysis. The World View variables then are analyzed as a set with 14 self-reported health variables for husbands and wives separately, using canonical correlation. The PCAs for family World View yielded poor solutions for both husbands and wives. The MDS displayed the eight variables in a circular pattern for husbands and for wives, indicating the absence of a single broad dimension, or subgroupings of separate dimensions, that could be used to "describe" the domain. In the canonical analyses, family World View was a strong correlate of Health, with approximately 50% of the variance accounted for by the respective canonical variates. For husbands, what we called Family Coherence, Family Religiousness, Family Life Engagement, and Family Optimism, were correlated with Health. For wives, Family Coherence, Family Religiousness, and Family Optimism, were correlated with Health. Different patterns of health scores emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: III. Family emotion management and adult health.

This article explores the broad patterning of interrelationships between family Emotion Management and adult Health in a community-based sample of 225 families. Emotion Management refers to how emotion is expressed, acknowledged, and managed by the marital partners. Fifteen reliable-observer ratings of husband-wife behavior were made during each of three 10-minute Emotion Management Interaction Tasks (EMITs). Each of the three tasks "pulled" for the expression of a different emotional theme: loss, intimacy, or conflict. A principle components analysis of the 15 ratings yielded a poor solution. A nonmetric, multidimensional scaling analysis described a two-dimensional, bipolar display with ordering among the variables in each of two wings. One dimension reflected positive versus negative Emotion Management characteristics, and the second reflected active and overt versus passive or covert emotional expression. The pattern of relationships among the couple ratings was similar for each of the three tasks. Using canonical correlation, the couple ratings demonstrated significant associations with 14 adult Health scores for both husbands and wives for the intimacy and conflict tasks, but not for the loss task. Specific gender patterns also emerged. In general, couple overt emotional aversiveness was negatively associated with husbands' health, and couple emotional avoidance/distance was negatively associated with wives' health.     

The effects of social support on children's eyewitness testimony

Child witnesses often give only short accounts of witnessed events. Part of the reason for this failing centres on the stress present during an interview. The most obvious means of reducing stress in children, through the provision of social support, has typically been neglected in eyewitness research, presumably because of fears over children's excessive suggestibility. Social support is also believed to inhibit children during interviews. However, these fears appear to stem more from general suspicions about children's competencies rather than empirical findings. Studies are described which show that child witnesses express a strong desire for social support, and that support may be provided in a number of different ways, from peers as well as adults. It is argued that social support is one of the most unfairly neglected issues in eyewitness research, and the minimal evidence available suggests that allowing support may have a facilitative effect on task performance, including free-recall memory.     

Verbal hallucinations in normals,I: People who hear ‘voices’

Two studies are reported that describe the phenomena of verbal hallucinations in the general population and test two explanations of those reports. Subjects were 198 male and 387 female college students who completed a verbal hallucination questionnaire plus one or more additional questionnaires. We found that a large minority reported hallucinations and that nearly half reported having them at least once a month. The present data indicated that these reports were not related to four measures of social conformity. Neither were they related to measures of overt, or incipient, symptoms of psychopathology. We have concluded that the majority of these reports are generally veridical accounts of conscious experience in normal individuals.     

Gender and family therapy: Adding a bi-level belief systems component to assessment

This article proposes that most couples requesting therapy describe gender socialized patterns as part of their relationship issues. Adding a component to assessment derived from principles of strategic and systemic family therapies and post-modernist feminist psychology which examines the couple's gendered belief system context is described. The belief system context is identified as the family's epistemology about gendering at the family belief system and sociocultural belief system level contexts. Three dimensions of the gendered belief system and a method for assessing the functionality of the belief system are discussed.     

An inexpensive automated system for the measurement of rotational behavior in small animals

A reliable, low-cost automated system for the quantification of rotational behavior from up to 10 subjects simultaneously is described. The system resolves quarter and full turns to the left and right, and can relay data to another computer for statistical analysis. The system is easily constructed from simple and inexpensive components, including the computer, that total less than $1,000 and can be used with a variety of different test chambers.
