[edit] Behavior analysis

Contingencies, uncertainity, and attachment

The behavioral model of attachment recognizes the role of uncertainity and uncertainity reduction. An infant is helpless and born into an uncertain world. From its earliest moments, the infant relies on the parent for many types of reinforcers such as heat (human infants do not thermoregulate well), food, water and protection. In addition, infants have a very limited repertiore for communicating such needs. Actions that produce contingent responding on the parents part are highly valued.[1] Thus at the heart of behavior analytic theories is the importance of contingent relationships.[2][3][4] The importance of contingency appears to be highlighted in other developmental theories;[5] however, many traditional developmental psychologists fail to recognize that contingency needs to be determined by two conditional probabilities.[6] In short, it is not just the efficiency of the action but the efficiency of the act compared to all other acts that the infant may perform at that point.

It is through the learning of contingent relationships that infants and adults are able to function within their environment. Research has shown that contingent relationships lead to more emotionally satisfying relationships.[7]

As early as the 1960s, behavioral research showed that parental responsiveness toward the infant on separation predicted identified outcomes in the "stranger situation" and modified versions of this preparation.[8] In one study six, 8 to 10 month old infants were run through four test conditions. The study was a classic reversal design (see single-subject research). The study assessed infant approach rate to the stranger. If attention was based on stranger avoidence the infant avoided the stranger. If attention was placed on infant approach, the infant approached the stranger.[9]

Recent meta-ananlytic studies of the behavioral development model of attachment based on contingency find that it has a moderate effect size, which increases to a large effect size when the quality of reinforcement is considered.[10] Recent research on the study of contingency highlights the matching quality[11] and places it in the diadic context[12][13] In addition, such studies have shown that contingencies can affect the development of both prosocial and antisocial behavior.[14][15][16][17] Indeed, training parents to become sensitive to the function of children's behavior and to respond behaviorally has a very large effect size[18]

The infants sensativity to contingency can be effected by biological factors (philogentic),[19] as well as being placed in irratic environments which contain few contingencies.[20] Less sensativity to contingencies can set the child up to have conduct problems[21] Loss of contingency could lead to depression (see Behavioral Development and Depression below).

Research and theory continue to look at the effects of learning based attachment on moral development.[22] Erratic use of contingencies early in life can produce devastating effects later[23]

Behavior analysis of socialization

Studies in behavior analysis of development observed the extended pattern of using rewards on behavior over time. The model focuses on two levels a micro and macro-analysis. The micro-analysis studies the moment to moment interactions while a macro-analysis focuses on parenting variables. Over the last few decades, longitudinal studies have lent credence to the idea that the use of reinforcement and punishment over extended periods of time lead to the development of prosocial,[24] antisocial,[25][26]and sick behavior.[27] Midlarsky and colleagues (1973) used a combination of modeling and reinforcement to build altruistic behavior.[28] At least two studies exist in which modeling by itself did not increase prosocial behavior;[29][30] however, modeling is much more effective then instruction giving such as "preaching"[31][32]The role of rewards has been implicated in the building of self-control[33] and empathy.[34][35][36] Cooperation seems particularly susceptible to rewards.[37][38][39][40] Sharing is another prosocial behavior influenced by reinforcement.[41][42] Reinforcement is particularly effective at least early in the learning series if context conditions are similar.[43] Evidence exists to show some generalization.[44] While reinforcement is generally accepted, the role of punishment has been more controversial.

Studying the role of punishment an interesting batch of studies exist. One study found that donation rates of children could be increased by punishing episodes of failure to donate[45]

The socialization process continues by teachers and by peers with reinforcement and punishment playing major roles. Peers are more likely to punish cross gender play and reinforce play specific to gender.[46][47][48] In the school older studies found that teachers were more likely to reinforce dependent behavior in females.[49] Such patterns have been found to contribute to gender differences at least in the short run[50]

Behavioral principles have also been researched in emerging peer groups with focus on status.[51] Such research as found that neglected boys are the least interactive and aversive, yet remain relatively unknown in groups. This research also suggests that it takes different social skills to enter groups then to maintain or build status in groups. Other research has found that withdrawn behavior can be decreased with a corresponding increase in social interactions for children[52]

The tradition continues to grow with its focus on moral and prosocial behavior. Recent efforts by Pelaez-Nogueras & Gewirtz (1995)[53] are of interest. They presented a comprehensive conceptual behavior-analytical approach to the basic behavioral processes that are thought to be involved in the acquisition and maintenance of early moral behavior patterns. Their analysis emphasizes that what has been termed “moral” behavior of an individual is ultimately the result of a history of socio-environmental contingencies affected by the consequences of that individual’s behavior. They illustrated how the operant-learning paradigm, with its emphasis on action and extrinsic stimuli, can account for much moral behavior as an outcome of conditioning processes. In this analysis, various processes are proposed for pre- and post-language acquisition individuals, taking into account behaviors that are public or private, non-verbal or verbal, and that may denote altruism, empathy, self-sacrifice, sharing, caring, conscience, justice, loyalty, or virtue. In this conceptual work, they noted the distinction between direct contingency-shaped behavior and rule-governed behavior in which moral behavior is seen initially as under the control of nonverbalizable direct contingencies in prelinguistic children. Later, with advances in the child’s language skills, much of that behavior is seen as coming under the control of verbalizable explicit rules (including both those that are self-formulated and those provided by others). This behavior analytic approach details the features of the operant-learning paradigm efficiently to explain the very same phenomena in the moral realm that nonbehavioral cognitive and mentalistic theories have targeted, at the same time that it attempts to fill in details that cognitive-developmental postulates seem to require. Moreover, this work offered a basic behavior analytic explanations of moral phenomena not previously analyzed. They emphasized behavioral outcomes as well as on antecedent and concurrent verbalizations of those behaviors (including verbal reasoning and moral judgment that have been the study matter of cognitive-developmental theories), the model may provide some leads on how to deal with overt actions in the moral realm.

Behavior analysis and antisocial behavior

In the development of antisocial behavior, etiological models for antisocial behavior show considerable correlation with negative reinforcement and response matching (see matching law).[54][55][56] Such models have consistently found a role for escape conditioning through the use of coercive behavior as having a powerful effect on the development and use of future antisocial tactics. From this view, antisocial behavior can be seen as functional for the child in moment to moment interactions. The rate of pro-social tactics used to antisocial tactics used during conflicts is directly proportional to the payoff.[57] This model explains 76% of the variance in child's chosen tactics and over 56% of the variance in the parents chosen tactics. Finally, the tactic payoff model predicted arrest rates two years later.[58] Interventions based on this model are developing as enhancements to the typical behavioral parent training model[59]

The role of stimulus control has also been extensively explored in the development of antisocial behavior[60] Using lag sequential analysis, researchers have been able to describe the immediate impact of one person's behavior on another in the family. Such patterns showed that overlearning was so rampant that the behavior was automatic and cognitive awareness was neither necessary nor sufficient to explain the interactions[61][62]

Recent behavioral focus in the study of antisocial behavior has been a focus on rule governed behavior. While correspondence for saying and doing has long been an interest for behavior analysts in normal development and typical socialization,[63][64][65] recent conceptualizations have been built around families that actively train children in antisocial rules[66] as well as children who fail to develop rule control[67]

Behavior analysis of cognitive behavior

As children get older, direct control of contingencies is modified by the presence of rule governed behavior[68]While the size of the effects on intellectual development are less clear, it appears that stimulation does have a facilitative effect on intellectual ability.[69] However, it is important to be sure not to confuse the enhancing effect with the initial causal effect.[70] Some data exists to show that children with developmental delays take more learning trials to acquire in material[71]

Behavior analysis of cognitive development

Following the fall of the soviet backed government in Romania in 1989, international adoption became a legal practice again. In 1991, a study was started that followed the development of orphans from the Romania orphanage to their new homes four years later. In total seventy Canadian children were divided into three different groups. These groups related the orphanage against a normal childhood upbringing. The researchers interviewed the subjects and paired each of them with a similar subject in an opposing group, matching exact age and gender. The groups were Romanian Orphans, Canadian Born, and Early Adoption.

There were twenty-four Romanian orphans were followed after adoption. These children stayed in the orphanage for at least eight months of the first year of their life. Also children in this group where monitored to see if they were favored by the workers at the orphanage, to see if they received special care or attention. The twenty-four Canadian Born children were set up as a control group. These children were born in traditional, nuclear families. These were not Romanian children; the only thing they had in common with their counterpart was exact age and gender. The third group was a smaller variable group where the researchers looked at eleven children that had been adopted from the orphanage less than four months from birth. These children were picked to determine if the amount of time in the orphanage had any effect on development at all.

When the children were on average, two researchers would interview the parents and the child separately. The parents were interviewed to determine the type of environment the child had lived in. The child was given a Stanford-Binet Intelligence Scale IQ test. The preconception was that the Romanian group would score lower than both the Canadian group and the early adopted. The results show that the Romanian children have what is considered healthy brain activity, but show a deficiency in higher power motor skills and cognitive processes. This supports the researchers claims that early childhood institutionalization directly affects the cognitive development of a child.

The early adoption group proved little results against either group. All eleven children in the group scored in between the Romanian and the Canadian groups in the IQ tests, yet there were not enough subjects in the group to give it credibility. But, one can take from this data that adoption before four months does increase the child’s chances of cognitive growth.[72]

Opportunity to respond, learned units, and developmental retardation

Behavior analysts have spent considerable time measuring learning in the classroom and in the home. Recent work has been on a model of "developmental retardation".[73] Often research in this area looks at cumulative environmental effects and how they create developmental delays. The opportunity to respond is defined as an instructional antecedent and its success in getting the appropriate response, sometimes fluency is used to measure this.[74] The learned unit is defined as the opportunity to respond plus reinforcement[75]

In one study using this model, students time of instruction was compared in affluent schools to poorer schools. Actual amount of instruction received revealed that poorer school lost on average about 15 minutes/day in instruction due to issues of classroom management This compiled to 2 years worth of lost instructional time by the 10th grade[76]

Behavior analysis and class formation

The formation of class-like behavior has been of considerable interest to behavior analysts studying development. Extensive research has been done in this area.[77] From this research, behavior analysts have offered multiple paths to the development and formation of class-like behavior. These paths include primary stimulus generalization,[78][79] an analysis of abstraction[80],[81][82][83][84][85] relational frames theory[86][87][88][89] stimulus class analysis (sometimes referred to as recombinative generalization),[90][91] stimulus equivalence,[92] and response class analysis[93].[94][95][96][97][98] Of particular interest is the analysis of the response class. Multiple process's for class like formation provide behavior analysts with relatively pragmatic explanations for common issues of novelty and generalization.

Responses organize in a form assembled by the particular form need to fit the environmental challenge at hand. Thus, the forms of the responses organize by responses functional consequences. Such large response classes can merge as in the case of contingency adduction.[99] Much more research needs to be done on the issue of contingency adduction, especially with a focus on how large classes of concepts shift. For example, as Piaget pointed out have a tendency at the pre-operational stage to have limits to their ability to conserver (Piaget & Szeminska, 1952). While training children to develop conservation skills has been generally successful[100][101] it is by no means easy.[102] Behavior analysts argue that this is largely due to the number of tool skills that need to be developed and integrated. Adduction offers a process by which such skills can be synthesized and hence warrants further attention, particularly by early interventionists. Even with this said, children who learn to conserve early do not appear to have any other life benefit from the learning process.[103] This last brings up questions of the relevance of Piaget's model to development.

Behavior analysis of child development's role in education

In the field of education, in 1968, Siegfried Englemann used operant conditioning techniques, a task analysis of curriculum, and combined them with rule learning to produce the Direct Instruction curriculum.[104]In addition, Fred Keller used similar techniques to develop programmed instruction. Skinner developed a programmed instruction curriculum for teaching hand writing. One of Skinner's students, Ogden Lindsley, developed a standardized semilogrithmic chart, the "Standard Behavior Chart" now "Standard Celeration Chart" for recording frequencies of behavior,and to allow direct visual comparisons of such frequencies and changes in those frequencies, termed "celeration". Use of this charting tool for analysis of instructional effect or other environmental variable by direct measurement of learner performance has become known as precision teaching.[105]

In education, there are many different kinds of learning that are required for later interaction in the world. Such aspects of learning include social, and language[106]These different areas of development are crucial for a growing child. And as technology continues to increase, its power has been spread to all areas. Technology can be used for good but too much of a good thing can have negative effects on a child or person. According to the NWREL (Northwest Regional Educational Laboratory), too much technology will hinder a child’s social interactions with others. There is always a fear that later in life, this early computer interaction will become an addiction and lead to antisocial behavior.[107]Not only is education and technology a big factor in child development, language always plays a big role. Language development doesn’t seem to have the same need for technology as social development does but studies show that some technology helps motor skills develop more efficiently. It is said that by the age of 18 months, a child will start to learn and know about 5 -20 different words[108]It is then understood that once the child knows these words, they go explore in the world and get a better understanding of this world.

Behavior analysis of motor development

Behavior analysts have held since the days of Watson that motor development represents a conditioning process. The argument is that crawling, climbing, and even the walking displayed by all typical infants represents conditioning of biologically pre-programmed reflexes. In this view, the nature end is represented by the innate respondent behavior (stepping) and these reflexes are environmentally conditioned through experience and practice. This position was critiqued by maturation theorists. On criticism was that the stepping reflex for infants appeared to disappear and thus was not "continuous." While working from a slightly different theoretical model but using operant conditioning and opportunity to respond techniques, Esther Thelen was able to show that children's stepping reflex disappears as a function of increased physical weight but if infants are placed in water, it returns.[109] This offered a plausible model for the continuity of the stepping reflex and thus the progressive stimulation model of the behavior analysts.

Indeed, infants deprived of physical stimulation or the opportunity to respond were found to have delayed motor development.[110][111] Under conditions of extra stimulation the motor behavior of these children rapidly improved.[112] One area of research has shown that treadmilling can be beneficial to children with motor delays including Down syndrome and cerebral palsy[113] Research on opportunity to respond and the building of motor development continues today[114][115][116]

Behavior analysis of developmental depression with origins in childhood

Behavioral theory of depression was outlined by Charles Ferster.[117] A later revision was provided by Peter Lewisohn and Hyman Hops. Hops continued the work on the role of negative reinforcement in maintaining depression with Anthony Bigland.[118][119][120][121] Additional factors such as the role of loss of contingent relations through extinction and punishment were taken from early work of Martin Seligman. The most recent summary and conceptual revisons of the behavioral model was provided by Johnathan Kanter.[122] The standard model is that depression has multiple paths to develop. It can be generated by five basic processes, including: lack or loss of positive reinforcement,[123] direct positive or negative reinforcement for depressive behavior, lack of rule-governed behavior or to much rule governed behavior, and/or to much environmental punishment. For children, some of these variables could set the pattern for life long problems. For example, a child who's depressive behavior functions for negative reinforcement by stopping fighting between parents could develop a life long pattern of depressive behavior in the case of conflicts. Two paths that are particularly important are (1) lack or loss of reinforcement because of missing necessary skills at a developmental cusp point or (2) the failure to develop adequate rule governed behavior. For the latter, the child could develop a pattern of always choosing the short term small immediate reward (i.e., escaping studying for a test) at the expense of the long term larger reward (failing courses in middle school).

Critiques of behavioral approach and new developments

Some have questioned if a behavioral approach to development is enough or do more traditional developmental variables play a causal role.[124] Particularly in areas of attachment.[125] While some questions remain, it is clear that in general, response contingent learning opportunities produce strong emotional benefits and enhance emotional development.[126] Behavior analytic theories have been criticized for focusing on explaining the acquisition of relatively simple behavior (the behavior of nonhuman species, of infants, and of individuals who are mentally retarded or autistic) rather than complex behavior (see Commons & Miller).[127] Commons continued behavior analysis's rejecting of mentalism and substituted task analyses. This approach shows that more complex behaviors combine and sequence less complex behaviors. This fact of hierarchical organization may be used to define the nature of stage and stage transition. In his new model, he has created a behavior analytic model of more complex behavior in line with more contemporary quantitative behavior analytic models. He calls this the model of hierarchical complexity. Commons (Commons, Trudeau, et. al 1998[128]) constructed the model of hierarchical complexity of tasks and their corresponding stages of performance using basically just three main axioms (see Model of hierarchical complexity).[129]

In the study of development, recent work has been generated around combining behavior analytic views with dynamical systems theory[130] The added benefit of this approach is that it shows how small patterns of changes in behavior in terms of principles and mechanisms over time can produce substantial changes in development.[131]

Current research in behavior analysis attempts to extend the patterns learned in childhood and to determine their impact on adult development
