A transactional systems model of autism services

There has been an escalation in the number of children identified with autism spectrum disorders in recent years. To increase the likelihood that treatments for these children are effective, interventions should be derived from sound theory and research evidence. Absent this supportive foundation, intervention programs could be inconsequential if not harmful. Although atypical, the development of children with autism should be considered initially from the perspective of the same variables that affect the development of typical children. In addition, the developmental deviations that characterize autism must be considered when developing intervention programs. Behavioral systems models describe both typical and atypical development and emphasize dynamic multidirectional person-environment transactions. The environment is viewed as having multiple levels, from the individuals with autism themselves, to larger societal and cultural levels. Behavioral systems models of human development can be generalized to a transactional systems model of services for children with autism. This model is the foundational theoretical position of the Southern Illinois University Center for Autism Spectrum Disorders. The center's programs are described to illustrate the application of the model to multiple levels of the social ecology.     

A transactional model of bullying and victimization

The purpose of the current study was to develop and test a transactional model, based on longitudinal data, capable to describe the existing interrelation between maternal behavior and child bullying and victimization experiences over time. The results confirmed the existence of such a model for bullying, but not for victimization in terms of maternal involvement, although a transactional relationship was supported for both bullying and victimization when considering conflict between parents and children. More specifically, the study’s results show that maternal involvement, including monitoring, predicts negatively both the initial value of bullying and its degree of change over time. In other words, the more a parent is involved, and the closer her supervision is, the less possible it is for her child to participate in bullying others activity. Moreover, the findings show that increases in bullying behavior on the part of the child cause a reduction in maternal involvement and monitoring over time. Finally, initial conflict between parents and children influence both bullying and victimization, and in turn, the development of bullying and victimization affects parent-child conflict. Hence, the findings of this study offer support to the hypothesis that parental and child behavior reciprocally influence each other, rather than one shaping the other in a unidirectional fashion.     

Prejudice and self-esteem: A transactional model

This paper reviews three theoretical models of how prejudice affects the self-esteem of its targets. The stimulus-response model assumes that prejudice has a direct, negative effect on self-esteem. The stimulus-perception-response model recognises that perceptions of prejudice may not directly mirror experiences with prejudice, but predicts that the subjective perception of being a target of prejudice has a direct, negative effect on self-esteem. Both of these models are found to be inadequate. We propose a third, transactional model, which assumes that individuals do not respond in uniform way to being the target of prejudice. Rather, this model contends that self-esteem and emotional responses to prejudice are determined by cognitive appraisals of prejudicial events and coping strategies used in response to these events; these processes, in turn, are shaped by personal, situational, and structural factors. Experiments are presented showing that self-esteem in response to perceived prejudice is moderated by presence or absence of threats to personal identity, clarity of prejudices cues in the situation, ingroup identification, dispositional optimism, endorsement of legitimising ideologies, and group status. We argue that a transactional model of responses to prejudice emphasises sources of resistance as well as vulnerability among targets of prejudice.     

A longitudinal transactional risk model for early eating disorder onset

The presence of binge eating behavior in early middle school predicts future diagnoses and health difficulties. We showed that this early binge eating behavior can be predicted by risk factors assessed in elementary school. We tested the acquired preparedness model of risk, which involves transactions among personality, psychosocial learning, and binge eating. In a sample of 1,906 children assessed in the spring of fifth grade (the last year of elementary school), the fall of sixth grade, and the spring of sixth grade, we found that fifth grade negative urgency (the personality tendency to act rashly when distressed) predicted subsequent increases in the expectancy that eating helps alleviate negative affect, which in turn predicted subsequent increases in binge eating behavior. This transactional risk process appeared to continue to occur at later time points. Negative urgency in the fall of sixth grade was predicted by fifth grade pubertal onset, binge eating behavior, and expectancies. In turn, it predicted increases in high-risk eating expectancies by the spring of sixth grade, and thus heightened risk.     

A role perception transactional process model for organizational communication-outcome relationships

This study presents a role perception transactional process model for organizational communication to understand and predict the relationships among organizational communications and employee satisfaction and performance. This transactional process model, being based on role perceptions, also represents a means by which to bridge organizational communication and organizational behavior. Dimensions of organizational communications, consistent with those used elsewhere, were used in this study in two organizations. In one organization data were collected on a longitudinal basis. Relationships among four dimensions of organizational communication, role perceptions and employee satisfaction and performance were examined. It was hypothesized that these variables would be reciprocally related and that role perceptions would intervene in the communication-outcome relationship. The results supported the hypothesized reciprocal relationships among these variables and the intervening effect of role perceptions. The results, therefore, generally supported the role perception transactional process model for organizational communication and the existence of vicious cycle phenomena in organizational communications and behavior.     

A componential analysis of pacemaker-counter timing systems

Why does counting improve the accuracy of temporal judgments? Killeen and Weiss (1987) provided a formal answer to this question, and this article provides tests of their analysis. In Experiments 1 and 2, subjects responded on a telegraph key as they reproduced different intervals. Individual response rates remained constant for different target times, as predicted. The variance of reproductions was recovered from the weighted sum of the first and second moments of the component timing and counting processes. Variance in timing long intervals was mainly due to counting error, as predicted. In Experiments 3-5, unconstrained response rate was measured and subjects responded at (a) their unconstrained rate, (b) faster, or (c) slower. When subjects responded at the preferred rate, the accuracy of time judgment improved. Deviations in rates tended to increase the variability of temporal estimates. Implications for pacemaker-counter models of timing are discussed.     

Transformational and transactional leaderships,empowerment climate,and innovation performance: A multilevel analysis in the Chinese context

Innovation through creativity is an important factor in the success and competitive advantage of organizations. Theory and research suggest that both leadership and organizational climate have important consequences for individual creativity. However, researchers have rarely considered the interactive effects of leadership and organizational climate. This study taking a “Substitute for Leadership” perspective, develops and tests the idea that empowerment climate affect the relationship between leadership and followers' creative performance. Data were collected from 93 teams, including 465 team members and 93 team supervisors, in a large multinational company based in China. Hierarchical linear modelling was used to examine the hypothesized cross-level model. As expected, transformational leadership and team empowerment climate were positively related to subordinates' creative performance and transactional leadership was negatively related to subordinates' creative performance. In addition, the relationship between leadership and subordinates' creative performance was moderated by team empowerment climate. The study resulted in the implication of several major variables for explaining individual creativity in the Chinese context.     

The transactional model of early home intervention

This article describes a developmental model for early home intervention and treatment of environmentally and biologically at-risk infants and their parents: The Transactional Model of Home Intervention. The model identifies the development of both infants and parents as targets of intervention and considers their ongoing interactions or transactions within the family context as the vehicle of intervention. The child and his physical/social environment are conceptualized as actively influencing one another in their reciprocal transactions. An early intervention program based on this transactional model is described. The intervention is tailored to suit the needs of both child and parents and, more generally, the needs of the family. The intervention process involves a problem-solving model of education by which parents acquire cognitive strategies that will enable them to assess the needs of their child and to design a program to fulfill these needs.     

Reward sensitivity in depression: a biobehavioral study

The approach-withdrawal model posits 2 neural systems of motivation and emotion and hypothesizes that these systems are responsible for individual differences in emotional reactivity, or affective styles. The model also proposes that depression is characterized by a deficit in reward-seeking behavior (i.e., approach motivation) and is associated with a relative decrease in left frontal brain activity. The authors tested aspects of this model by comparing the electroencephalogram alpha power of depressed and nondepressed individuals during a task that manipulated approach motivation. The study found that control participants and individuals with late-onset depression exhibited the hypothesized increase in left frontal activity during the approach task but individuals with early-onset depression did not. This suggests that early-onset depression may be associated with a deficit in the hypothesized approach motivation system.     

Stress and burnout among French elementary school teachers: A transactional approach

Teachers meet increasing difficulties in their work: overwork, students dropping out of the system, the discredit of the profession among users of the educational system. These problems are stressors which have an influence on the vulnerability of teachers and lead to burnout. The transactional model of stress by Lazarus and Folkman [Lazarus, R.S., Folkman, S., 1984. Stress, appraisal and coping, New York, Springer] emphasizes the importance of the activity expended by an individual in order to confront a stressful situation. We administered several questionnaires to 410 French elementary schoolteachers during the first term (T1) in order to evaluate: their sociobiographic characteristics; the frequency of professional problems; perceived self-efficacy; social support; and their coping strategies. The burnout of 259 teachers of the same cohort was evaluated during the third term (T2). The results of this research show the interest of taking into account transactional processes in order to study the effects of professional stress on burnout.     

A systems analysis of the behaviors of schooling

Summary and conclusions Thus, the existing nonsystematic system, and the various vested interests associated with it, targets groups of students rather than individuals. Prior to the advent of a science of schooling, the tutorial approach associated with the privileged or ruling classes did not seem feasible for educating the masses, simply because there was no adequate science of behavior for the individual. Even after that science showed promise for pedagogy, there was still no systems-wide science for applying what was known to groups and organizations in which the individual was pivotal. In order to determine whether behavioral conceptions of schooling work on a larger scale, we must experimentally test whether or not thoroughgoing applications are feasible to educate the masses individually. Findings from 8this research can be used to design and modify systems of schooling that are measurably effective, workable year in and year out, automatically self-correcting, and beneficial to all of the parties involved. CABAS has demonstrated how such a system can work on a small scale; other attempts may show us how to make a large scale system work. We have not yet seen what man can make of man (Skinner, 1971, p. 215).     

Evolving the biobehavioral family model: the fit of attachment

The 1993 Biobehavioral Family model (BBFM) posits that family relational patterns and biobehavioral reactivity interact so as to influence the physical and psychological health of the children. The revised 1999 BBFM incorporates parent-child attachment as a pivotal construct. The current study tests the 1999 BBFM by predicting, in asthmatic children, that child perception of parental relationship quality, triangulation of child in marital conflict, and parent-child security of relatedness will be associated with hopelessness and vagal activation (one mechanism of airway compromise in asthma). In this study, 22 children with asthma (11 males/11 females, aged 8 to 16), watched, alone, an emotionally challenging movie, then engaged in family discussion tasks (problem solving, loss, conflict, cohesion) and completed the Children's Perception of Interparental Scale, the Relatedness Questionnaire, The Multidimensional Scale of Anxiety in Children, and the Hopelessness Scale for Children. Heart rate variability, measured at baseline and throughout the movie and family tasks, was used to compute respiratory sinus arrhythmia (RSA)--an inferential measure of vagal activation. The child's perception of parental conflict showed trends of association with triangulation and insecure father-child relatedness. Triangulation and hopelessness also were associated with insecure father-child relatedness, all of which were associated with vagal activation. Insecure mother-child relatedness was correlated only with hopelessness. Anxiety was not related to any variables. These findings lend support to the 1999 BBFM, and suggest a key role for parent-child attachment.
