The generalization of newly acquired behaviors by parents and child across three different settings

The generalization of newly learned behaviors to different settings on the part of an autistic child and his parents was investigated by means of a multiple baseline design. Contingency management techniques were taught to the parents while they interacted with their child in a training apartment equipped with observation facilities. In order to assess whether the parents generalized the use of these techniques, data were gathered at their own home. Data were also gathered in the child's school in order to ascertain whether changes brought about in the child's behavior in the training apartment generalized to the school situation. It was concluded that the child's behavior was responsive to the contingencies of each particular environment. Generalization did not occur until the contingencies and stimulus cues were specifically designed to promote a change in behavior in each setting.     

Generalization in a child's oppositional behavior across home and school settings

A 9-year-old clinic-referred boy, his mother, and his teacher were observed in 38 home and 38 school sessions on the same days. Categories of the boy's oppositional behavior and the inappropriate social attention of his mother and teacher were graphed to visually inspect changes during baseline, a parent-training phase, a follow-up phase, and a final parent-training booster phase. Parent-training phases produced reductions in the mother's inappropriate attention and in the boy's oppositional behavior, whereas the follow-up and baseline phases were associated with higher rates of these categories. Generalization occurred in the school across these home phases, as seen in the increase in rates of the boy's problem behavior, despite the lack of change in his teacher's attention. Correlational analyses of proportion scores reflecting the boy's home-school oppositional behavior and mother-teacher social attention suggested his responsiveness to relative changes in adult social contingencies across settings.     

An examination of behavioral consistency using individual behaviors or groups of behaviors in serial homicide

Establishing behavioral consistency in serial homicide offending behavior is essential when linking homicides together and to a common offender. An examination of 35 serial homicide behaviors utilized by 90 offenders in 450 serial homicide cases was carried out to identify whether these offenders consistently performed the same behaviors across their series of homicides and whether it is more effective to examine individual behaviors or groupings of behaviors in order to identify behavioral consistency. This study provides the first empirically based evidence testing the use of using single behaviors as linking factors in linking homicide cases in a series, and shows that this method has inherent difficulties in accomplishing this, thus providing the first wave of empirical testing that questions current theories in the literature on serial homicide, which has suggested that signatures or specific key behaviors are important in understanding the consistency in an offender's behavior across the crimes. Recommendations for future studies on linking using signatures are suggested, including a more in-depth qualitative empirical evaluation of individual series.     

Accelerating stimuli for two classes of coercive behaviors

The analyses focused on a means by which classes of events may be derived from sequential data. A prior analyses of family interaction has derived two classes labeled Hostile and Social Aggression. Events in a class were initiated by a common network of antecedent behaviors. The current analyses showed that class members also shared a common set of maintaining consequences. These events correlated with altered probabilities for the immediate recurrence of a target event.     

An evaluation of reciprocal peer tutoring across elementary school settings

The effects of a reciprocal peer tutoring (RPT) intervention on the arithmetic performance of 12 low-income, underachieving elementary school students across three elementary school settings were evaluated and a partial component analysis was conducted. The results indicated that merely teaming students and providing them with positive attention for constructive team activities had no clear effect on arithmetic performance. An RPT condition that involved peer-managed group contingencies yielded consistent increases in rate of accurate arithmetic performance to a level that was significantly above the rates of untreated control students. Attendance and maintenance data also supported the efficacy of the intervention.     

Longitudinal consistency of adolescent ethnic identification across varying school ethnic contexts

The present study examined consistency and inconsistency in adolescents' ethnic identification (i.e., self-reported ethnicity) across the 6 middle-school semesters. The sample (N = 1,589, of whom 46% were boys and 54% were girls) included African American, Asian/Pacific Islander, Caucasian/White, Latino/Latina, Mexican/Mexican American, and multiethnic students. Latent class analyses yielded 3 key patterns in ethnic identification across the middle-school years: consistent, late consistent, and inconsistent. Ethnic identification remained consistent across fall and spring of 6th, 7th, and 8th grades for only about 60% of the students. Asian/Pacific Islander students were more consistent, and multiethnic students were less consistent than students from other ethnic groups. School ethnic composition was associated with systematic shifts in ethnic identification from the beginning to the end of middle school for those students who initially identified as Latino/Latina, African American, or multiethnic but not for Mexican-origin students. In combination, the results provide insight into the consistency of ethnic identification, the role of context in adolescents' self-representation, and considerations for longitudinal studies that examine ethnic differences.     

The consistency of hysteric traits across three situational contexts

The consistency of personality traits across three situational contexts was demonstrated, thereby supporting the view of the individual as creator of societal groups and institutions. Nineteen sorority members were administered the Multivariate Personality Inventory (MPI), an instrument that assesses eight trait styles derived from a multivariate theory of personality in three conditions varying in both temporal order and immediate strength of sorority activity. As predicted, greater endorsement of the hysteric style was found for sorority members and the endorsement remained consistent across the three situational conditions. Results are discussed in light of the view that traits are fairly comparable across situations even though social behavior could vary depending upon the demands of the situation.     

The functional significance of autistic behaviors for the psychotic child

Physiological, cognitive, and emotional factors were examined throughout the treatment of a psychotic child. Heart rate, latency and accuracy in task performance, behavioral indices of stress (e.g., muscular tension, facial expression), and frequency of autistic mannerisms were measured concurrently. Both contemporaneous relationships and patterns of change suggested that autistic behaviors were organized and psychologically meaningful. Self-stimulation, conflict, and negativism (deliberate erroneous performance) occurred predictably, were intimately related, and were associated with specific patterns of heart-rate change. The changing function of self-stimulation across treatment and the centrality of negativism in this child's disturbance were discussed.This research was supported in part by a Program Project Grant from the National Institute of Child Health and Human Development to the Institute of Child Development, University of Minnesota (1 PO1 IID05027).     

An evaluation of a perceived overqualification scale across work settings

The authors extended and evaluated the dimensionality of the L. J. Khan and P. C. Morrow (1991) subjective underemployment scale. They used data from 3 independent samples to assess the measurement properties of the scale. The results of confirmatory factor analyses supported 2 dimensions and indicated that the measurement model parameters partially generalized across samples. Correlational and additional confirmatory factor analytic results rendered empirical support for most of the postulated relationships of the 2 overqualification dimensions with the somatization, job satisfaction, and organizational commitment variables. The findings indicate that the scale of perceived overqualification needs to be further developed and validated in different samples. The implications of the findings for person-job fit are discussed.     

A responsive parenting intervention: the optimal timing across early childhood for impacting maternal behaviors and child outcomes

This study examined the optimal timing (infancy, toddler-preschool, or both) for facilitating responsive parenting and the intervention effects on maternal behaviors and child social and communication skills for children who vary in biological risk. The intervention during infancy, Playing and Learning Strategies (PALS I), showed strong changes in maternal affective-emotional and cognitively responsive behaviors and infants' development. However, it was hypothesized that a 2nd intervention dose in the toddler-preschool period was needed for optimal results. Families from the PALS I phase were rerandomized into either the PALS II, the toddler-preschool phase, or a Developmental Assessment Sessions condition, resulting in 4 groups. Facilitation of maternal warmth occurred best with the PALS I intervention, while cognitive responsive behaviors were best supported with the PALS II intervention. Behaviors that required responsiveness to the child's changing signals (contingent responsiveness, redirecting) required the intervention across both the early and later periods.     

The impact of childbirth settings and maternal medication on infant behaviors

The Brazelton Neonatal Behavioral Assessment Scale (BNBAS) was administered to 61 full-term, healthy newborns between 7–10 days of age. Three groups of newborns made up the sample: 23 babies were born at planned home births to nonmedicated mothers, 22 were born in the hospital to nonmedicated mothers, and 16 neonates were born in the hospital to mothers who received obsteric medication. Analysis of variance indicated a significant F ratio on the BNBAS cluster for orienting behaviors; comparison of the BNBAS scores of the three groups revealed a significant difference on the BNBAS cluster for orienting behavior between the home-born babies and infants born in the hospital to mothers who received obsteric medication. There was no significant difference between groups for medication or birth setting alone, suggesting these perinatal factors have a complex, perhaps synergistic effect on newborn behavior.     

Action-control beliefs and behaviors as predictors of change in adjustment across the transition to middle school

Abstract

We examined longitudinal changes in young adolescents’ (N=368) action-control beliefs, coping behaviors, and adjustment (i.e., positive and negative affect, depression, aggression) across the transition from elementary school to middle school. Results indicated greater inter-individual instability in adjustment during this transition than during the previous school year. Using ordinary least-squares (OLS) growth models to extract intra-individual change scores for each variable (i.e., slopes and intercepts), we conducted a series of stepwise regressions to determine which features of control beliefs and coping behaviors best predicted changes in adjustment across the transition to middle school. We found that negative coping behaviors (i.e., antisocial coping) consistently predicted negative changes in the adjustment variables (e.g., greater depression, more aggression), whereas positive beliefs and behaviors did not consistently predict changes in the adjustment variables.     

Young children's interpersonal trust consistency as a predictor of future school adjustment

Young children's interpersonal trust consistency was examined as a predictor of future school adjustment. One hundred and ninety two (95 male and 97 female, M_age = 6 years 2 months, SD_age = 6 months) children from school years 1 and 2 in the United Kingdom were tested twice over one year. Children completed measures of peer trust and school adjustment and teachers completed the Short-Form Teacher Rating Scale of School Adjustment. Longitudinal quadratic relationships emerged between consistency of children's peer trust beliefs and peer-reported trustworthiness and school adjustment and these varied according to social group, facet of trust, and indicator of school adjustment. The findings support the conclusion that interpersonal trust consistency, especially for secret-keeping, predicts aspects of young children's school adjustment.     

The effects and side effects of punishing the autistic behaviors of a deviant child

Timeout procedures in the home and extinction and reinforcement of incompatible behaviors in the laboratory failed to eliminate the disruptive and dangerous climbing behavior of a deviant child. Punishment with electric shock was used to eliminate this behavior in the laboratory and then in the home. The effects were reversible and were restricted to specific stimulus conditions. A less severe form of punishment was used to eliminate the child's autistic rocking. Other behaviors of the subject were continuously measured in the laboratory to determine the side effects of punishment. No suppression of other behaviors correlated with punishment was noted. However, the rate of some behaviors increased when punishment was used to eliminate deviant behaviors, but these increases were, primarily, desirable.     

The impacts of ignoring individual mobility across clusters in estimating a piecewise growth model

A three-level piecewise growth model (3L-PGM) can be used to break up nonlinear growth into multiple components, providing the opportunity to examine potential sources of variation in individual and contextual growth within different segments of the model. The conventional 3L-PGM assumes that the data are strictly hierarchical in nature, where measurement occasions (level 1) are nested within individuals (level 2) who are members of a single cluster (level 3). However, in longitudinal research, it is sometimes difficult for data structures to remain purely clustered during a study, such as when some students change classrooms or schools over time. One resulting data structure in this situation is known as a multiple membership structure, where some lower-level units are members of more than one higher-level unit. The new multiple membership PGM (MM-PGM) extends the 3L-PGM to handle multiple membership data structures frequently found in the social sciences. This study sought to examine the consequences of ignoring individual mobility across clusters when estimating a 3L-PGM in comparison to estimating a MM-PGM. MM-PGM estimates were less biased (especially in the cluster-level coefficient estimates), although we found substantial bias in cluster-level variance components across some conditions for both models.     

The school psychologist as a behavior management consultant in a special class setting

The efficacy of the consultant's role in dealing with problems in large special classes and the value of introducing operant techniques through untrained teachers were investigated in the present study. Twenty-two out-of-control boys in a special class for emotionally disturbed children were brought under the control of a number of token reinforcement systems with a resultant increase in task-oriented behavior and academic productivity. With teachers acting as observer-recorders and behavior change agents the school psychologist was able to minimize his role as a consultant with considerable success.     

The consistency of inconsistency in serial homicide: patterns of behavioural change across series

Linkage analysis is a crucial part of the investigative process when faced with a possible series of related offences. Establishing behavioural consistency (i.e., offender's behaviours consistently present across the series) is at the core of linkage. Recent empirical studies have found little evidence of consistency looking at either individual or groups of behaviours in serial homicide. It is argued that behavioural changes are rooted in the changing cognitive strategies that offenders use to reach their ultimate goal (i.e. the commission of multiple homicides). Factors that could account for these changes include learning, situational factors, loss of control, and changes in the offender's fantasy. Patterns of behavioural change have been identified in serial crimes, such as rape. However, no empirical studies have looked at patterns of behavioural change in serial homicide. The present study examined patterns of consistency and change using a combination of thematic and behavioural subgroup approaches that use Multidimensional Scaling. Thematic differentiation indicative of behavioural manifestations of cognitive strategies was found in all three examined subgroups: planning, wounding, and offender–victim interaction, and patterns of change within these subgroups provided support for the above theories. Looking at behavioural patterns rather than individual behaviours, may be a more fruitful way of examining consistency in serial homicide, and could have significant implications for linkage analysis.

Perceptions and behaviors of dogmatic subjects in a T-group setting.

Ss scoring 1 SD above or below the mean of the Rokeach Dogmatism Scale, Form E participated. During 12 hr. of training, Ss' behaviors were recorded by observers and each S was periodically rated by his peers on his perceived level of contributions to the group process. Significant differences were found between high and low dogmatics in the behaviors exhibited during the T-groups. Low dogmatics were more self-revealing, more attentive to the here-and-now aspects of the T-group, less apt to give negative feedback, and less likely to reject the group. A significant curvilinear relation was found between peer ratings and behavior in the T-group, with Ss who were rated extremely by their peers being more self-revealing, more attentive to the here-and-now of the group, more apt to give negative feedback, and less likely to reject the group verbally.
