[Preschoolers' understanding of characteristics of their friends' behavior: prediction of friends' behavior and behavioral intention toward friends].

These studies examined preschoolers' understanding of characteristics of friends. "Friends" were defined as children of the same sex who chose each other as good friends, and "acquaintances" were those who knew each other but did not mutually chosen. In Study 1, 30 five- to six-year-old children were asked how they expected their friends and acquaintances to behave toward them in various situations, such as play, help, and trust situations. It was found that they tended to expect their friends in play and trust situations to behave more kindly than their acquaintances. In Study 2, they were asked how they themselves would behave toward their friends and acquaintances in the same situations. They replied that they would behave more kindly toward their friends than toward their acquaintances in all the situations. These results were interpreted as preschoolers showing a consistent understanding of their friends' behavior, as well as a clear comprehension of reciprocity in their relationship with their friends.

[Variability and inheritance of behavior in fine-wool sheep. II. Character of inheritance of domesticated behavior and correlation of behavior with productivity traits in fine-wool sheep].

The results of an experimental study of the inheritance of individual behaviour in various types of crosses are presented; the phenotypic and genetic correlations between the behavior and producutivity characters in sheep and the possibility of applying behaviour characteristics to the selection process of fine-wool sheep are analysed. It is shown that the progeny from crosses between parents with the same type of behaviour inherits mainly the type of behaviour of their parents and that, in general, the inheritance has a polygenic character. A genetic relation between the type of domestic behaviour and the productive characters of fine-wool sheep is established. The genetic correlation coefficient between the behaviour and the wool productivity is 0,57, and that between the behaviour and the live weight is 0,53. It is concluded that the inheritance component contributes to the formation of the type of domestic behaviour of fine-wool sheep. Phenotypic and genetic correlations between the type of behaviour and the main productivity characters are discussed. The posibility of using behaviour characteristics as a character under selection is considered.

Covariations of eating behaviors with other health-related behaviors among adolescents.

PURPOSE: The study objectives are: (1) to examine and compare patterns of covariation of a wide range of health behaviors among adolescent boys and girls; (2) to determine whether eating behaviors are part of a larger construct of health-related behaviors and to identify the behaviors with which they share underlying similarities; and (3) to determine whether youth engaging in other health-compromising behaviors are at risk for unhealthy eating. METHODS: Data were analyzed from the Minnesota Adolescent Health Survey, a classroom-administered questionnaire, completed by 36,284 adolescents, in grades 7-12 from 1986-87. RESULTS: Among boys, factor analysis revealed five factors: (1) risk-taking behaviors, (2) school-related behaviors, (3) "quietly" disturbed behaviors (e.g., frequent dieting, self-induced vomiting, suicide attempts), (4) health-promoting behaviors; and (5) exercise. Eating behaviors loaded on the construct of health-promoting behaviors with brushing teeth and seat belt use. Among girls, four similar factors emerged; however, exercise loaded on the construct of health-promoting behaviors. Therefore, eating behaviors loaded with brushing teeth, seat belt use, and exercise among girls. Logistic regression analyses, controlling for sociodemographic and personal variables, revealed that boys and girls engaging in health-promoting behaviors were less likely to have unhealthy eating behaviors, while those engaging in quietly disturbed behaviors, risk-taking behaviors, and problematic school behaviors were more likely to have unhealthy eating behaviors. CONCLUSIONS: Eating behaviors appear to be part of a health-promoting behavioral construct and should not be viewed in isolation from other behaviors. Although eating behaviors do not appear to be part of the "problem behavior syndrome," youth engaging in a wide range of health-compromising behaviors are at risk for unhealthy eating; emphasizing the need to target high-risk youth with health promotion programs.

[On the improvement of everyday life behavior of chronic schizophrenic patients; from the viewpoint of "play-like behavior"].

In this study, the author examined the behavioral patterns of chronic schizophrenic inpatients to follow the process of the amelioration of abulic symptoms such as loss of interest, poverty of thought, lack of sociality, and poor communication. In everyday life in the ward, abulic patients had difficulties in accomplishing not only the basic habitual acts such as getting up or going to bed regularly, exchanging greetings, cleaning teeth, bathing, and washing clothes, but also their assigned duties on the ward. Furthermore, they were unable to behave according to the rules for inpatients, express their emotions appropriately, or build normal interpersonal relationship. The author found that five inpatients achieved some spontaneous behaviors of their own choices in the process of improvement in the above-mentioned habitual acts. As these spontaneous behaviors proceeded through several phases, obvious improvements in their behavioral patterns in everyday life were also observed. The initial phase of transient spontaneous behavior was followed by the second phase of continual spontaneous behavior. Finally, in the interview sessions, the patients became to express pleasurable emotions and physical feelings when they performed their own acts of continual spontaneous behavior. This phenomenon seemed valuable in the therapeutic context because schizophrenic patients are considered seldom capable of having positive feelings toward their own experiences. Therefore, these pleasurable continual spontaneous behaviors may be called "play-like behavior", as confirmed by comparison with the properties of "play" as defined by Caillois. In considering schizophrenic autism, Minkowski described "activité autiste" as an intrinsic quality of the way of life in schizophrenic patients. The manifestation of such quality in spontaneous behaviors can be regarded as having two meanings; an aspect of pathological acting out and a sign of recovery to realistic behaviors. Therapists should consider both aspects when conducting therapies. Although the patients regained the habits and norms of everyday life during hospitalization, the rules involved in "play-like" behavior seemed to contradict some rules in the habitual acts or assigned duties in their daily lives because within "play-like" behavior, freedom predominates over rules. The rules in "play-like" behavior are acquired mostly by mimicking other people. These rules are not fixed laws with penalties but are changeable rules depending on the circumstances of the behavioral process. From this viewpoint, "play-like" behavior allows the patients to acquire practical rules and to understand the relative nature of the rules. Most of the "play-like" behaviors originate from the preferences of the individual patients, which may be something that they have already experienced, something that they have longed for, or something that gives them self-fulfillment. These qualities contribute to the acquisition of experiences that they find pleasurable. For the patients, recalling each "play-like" behavior in the interview sessions enables them to grasp the whole picture of their behaviors, to reinforce their attachment to these behaviors as their own experiences, and to promote the dynamic process between behavior and thought. In this sense, psychotherapy incorporating the aspect of "play-like" behavior seems to prepare the schizophrenic patients to improve their way of thinking. To nurture "play-like" behavior helps the chronic schizophrenic patients to recover will power, independence and sociality, and contributes to the improvement of clinical symptoms and of daily life activities.

Behavioral transitions modulate hippocampal electroencephalogram correlates of open field behavior in the rat: support for a sensorimotor function of hippocampal rhythmical synchronous activity.

A clear relationship exists between moment-to-moment behavioral elements and hippocampal rhythmical synchronous activity (RSA) (theta rhythm). However, behavioral elements are not isolated events but are part of behavioral sequences in a context of behavioral activity. By concurrently monitoring open field behavior and hippocampal EEG, EEG correlates of open field behavior in relation to preceding and following behavior were studied in Sprague Dawley rats to determine whether the behavioral context influences EEG correlates of behavior. Results show that preceding and subsequent behavioral patterns influenced the spectral power correlates of behavior. RSA power was increased when a "type 1 behavior" (voluntary movement) preceded the behavior compared with when a "type 2 behavior" (automatic movement, awake immobility) preceded it. The modulating effect of behavioral transitions was shown for several types of behaviors, and systematic modulation of hippocampal EEG correlates of behavior was demonstrated. The present report shows that the strong and systematic relationship between hippocampal RSA and behavior is modulated by the behavioral-sequential context. Thus, in addition to the well established relationship between RSA and motor activity, a second nonmotor process seems to contribute to hippocampal RSA. A likely candidate is a sensory process, which is in accordance with theories on the sensorimotor function of hippocampal RSA.

Human behavioral momentum: implications for applied behavior analysis and therapy.

Recent behavioral studies have addressed the persistence of behavior under altered environmental conditions using more sophisticated techniques of behavior analysis which have direct relevance for applied behavior analysis and therapy. In clinical populations, for example, behavioral programs are concerned with issues such as generalizability of behavior and relapse prevention (Epstein, 1992). Free-operant behavior can be analyzed not only in terms of its response rate but also in terms of its persistence under changed environmental constraints. The aggregation of these two response measures, rate and persistence, has been termed behavioral momentum (Nevin, Mandell, & Atak, 1983). This study assessed behavioral momentum in a human population in order to test predictions made from the behavioral model and potential clinical applications of behavioral momentum to behavior analysis and therapy. Eight undergraduates served as subjects for this study. Results were consistent with the predictions based on behavioral momentum. Denser reinforcement schedules, regardless of response contingency, produced greater resistance to the implementation of changed contingency schedules. Results of this study may have direct application to behavior analysis programs. If humans, in clinical contexts, show similar patterns of persistence in behavior under changed environmental settings, schedules could be implemented that provide both contingent and non-contingent reinforcement, thereby strengthening behavior to give it greater generalizability outside of the immediate situation.

Behavioral cusps: a developmental and pragmatic concept for behavior analysis.

Most concepts of development explain certain behavior changes as products or markers of the invariable succession of emerging periods, stages, refinements, or achievements that define and order much of an individual's life. A different but comparable concept can be derived from the most basic mechanisms of behavior analysis, which are its environmental contingencies, and from its most basic strategy, which is to study behavior as its subject matter. From a behavior-analytic perspective, the most fundamental developmental questions are (a) whether these contingencies vary in any systematic way across the life span, and thus make behavior change in a correspondingly systematic way; (b) whether some of these contingencies and their changes have more far-reaching consequences than others, in terms of the importance to the organism and others, of the behavior classes they change. Certain behavior changes open the door to especially broad or especially important further behavior change, leading to the concept of the behavioral cusp. A behavioral cusp, then, is any behavior change that brings the organism's behavior into contact with new contingencies that have even more far-reaching consequences. Of all the environmental contingencies that change or maintain behavior, those that accomplish cusps are developmental. Behavior change remains the fundamental phenomenon of development for a behavior-analytic view; a cusp is a special instance of behavior change, a change crucial to what can come next.

The Good Behavior Game: a best practice candidate as a universal behavioral vaccine.

A "behavioral vaccine" provides an inoculation against morbidity or mortality, impacting physical, mental, or behavior disorders. An historical example of a behavioral vaccine is antiseptic hand washing to reduce childbed fever. In current society, issues with high levels of morbidity, such as substance abuse, delinquency, youth violence, and other behavioral disorders (multiproblems), cry out for a low-cost, widespread strategy as simple as antiseptic hand washing. Congruent research findings from longitudinal studies, twin studies, and other investigations suggest that a possibility might exist for a behavioral vaccine for multiproblem behavior. A simple behavioral strategy called the Good Behavior Game (GBG), which reinforces inhibition in a group context of elementary school, has substantial previous research to consider its use as a behavioral vaccine. The GBG is not a curriculum but rather a simple behavioral procedure from applied behavior analysis. Approximately 20 independent replications of the GBG across different grade levels, different types of students, different settings, and some with long-term follow-up show strong, consistent impact on impulsive, disruptive behaviors of children and teens as well as reductions in substance use or serious antisocial behaviors. The GBG, named as a "best practice" for the prevention of substance abuse or violent behavior by a number of federal agencies, is unique because it is the only practice implemented by individual teachers that is documented to have long-term effects. Presently, the GBG is only used in a small number of settings. However, near universal use of the GBG, in major political jurisdictions during the elementary years, could substantially reduce the incidence of substance use, antisocial behavior, and other adverse developmental or social consequences at a very modest cost, with very positive cost-effectiveness ratios.

Youth Risk Behavior Surveillance--National Alternative High School Youth Risk Behavior Survey, United States, 1998.

PROBLEM/CONDITION: Alternative high schools serve approximately 280,000 students nationwide who are at high risk for failing or dropping out of regular high school or who have been expelled from regular high school because of illegal activity or behavioral problems. Such settings provide important opportunities for delivering health promotion education and services to these youth and young adults. However, before this survey, the prevalence of health-risk behaviors among students attending alternative high schools nationwide was unknown. REPORTING PERIOD: February-May 1998. DESCRIPTION OF SYSTEM: The Youth Risk Behavior Surveillance System (YRBSS) monitors the following six categories of priority health-risk behaviors among youth and young adults: behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs) (including human immunodeficiency virus [HIV] infection); unhealthy dietary behaviors; and physical inactivity. The national Alternative High School Youth Risk Behavior Survey (ALT-YRBS) is one component of the YRBSS; it was conducted in 1998 to measure priority health-risk behaviors among students at alternative high schools. The 1998 ALT-YRBS used a three-stage cluster sample design to produce a nationally representative sample of students in grades 9-12 in the United States who attend alternative high schools. The school response rate was 81.0%, and the student response rate was 81.9%, resulting in an overall response rate of 66.3%. This report summarizes results from the 1998 ALT-YRBS. RESULTS AND INTERPRETATION: In the United States, 73.6% of all deaths among youth and young adults aged 10-24 years results from only four causes--motor vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 1998 ALT-YRBS demonstrate that many students at alternative high schools engage in behaviors that increase their likelihood of death from these four causes. During the 30 days preceding the survey, 51.9% had ridden with a driver who had been drinking alcohol, 25.1% had driven a vehicle after drinking alcohol, 32.9% had carried a weapon, 64.5% had drunk alcohol, and 53.0% had used marijuana. During the 12 months preceding the survey, 15.7% had attempted suicide, and 29.0% had rarely or never worn a seat belt. Substantial morbidity among school-aged youth and young adults also results from unintended pregnancies and STDs, including HIV infection. ALT-YRBS results indicate that in 1998, a total of 87.8% of students at alternative high schools had had sexual intercourse, 54.1% of sexually active students had not used a condom at last sexual intercourse, and 5.7% had ever injected an illegal drug. Among adults aged > or =25 years, 66.5% of all deaths result from two causes--cardiovascular disease and cancer. Most risk behaviors associated with these causes of death are initiated during adolescence. In 1998, a total of 64.1% of students at alternative high schools had smoked cigarettes during the 30 days preceding the survey, 38.3% had smoked a cigar during the 30 days preceding the survey, 71.2% had not eaten > or =5 servings of fruits and vegetables during the day preceding the survey, and 81.0% had not attended physical education (PE) class daily. Comparing ALT-YRBS results with 1997 national YRBS results demonstrates that the prevalence of most risk behaviors is higher among students attending alternative high schools compared with students at regular high schools. Some risk behaviors are more common among certain sex and racial/ethnic subgroups of students. PUBLIC HEALTH ACTION: ALT-YRBS data can be used nationwide by health and education officials to improve policies and programs designed to reduce risk behaviors associated with the leading causes of morbidity and mortality among students attending alternative high schools.

Suppression of receptive and proceptive behavior in ovariectomized, estrogen-progesterone-primed rats by intraventricular beta-endorphin: studies of behavioral specificity.

Intraventricular (i.c.v.) administration of beta-endorphin (beta-END) has been shown to suppress lordosis behavior in ovariectomized (OVX) estrogen-progesterone (EP) primed rats, but the behavioral specificity of this effect is not known. Using OVX EP-primed rats, the present study assessed the effect of i.c.v. beta-END on proceptive behavior as well as on lordosis (receptive) behavior, and attempted to discern whether the sexual effects were secondary to generalized nonspecific behavioral effects. Doses of 0.5-4 micrograms beta-END (human) significantly suppressed lordosis behavior. Doses of 1 and 4 micrograms were used in experiments which measured proceptive behaviors (presentations and ear wiggling), and both doses abolished or nearly abolished the display of these behaviors. Administration of inactive peptide (a protein digest) had no effect on sexual behavior. Neither 1 nor 4 micrograms beta-END elicited measurable catalepsy. In a series of tests for responsiveness to general somatosensory stimuli, 1 microgram had no effect on responsiveness while 4 micrograms had minor effects, even though sexual activity was severely diminished after both doses. Blood pressure was unaltered by infusion of beta-END (1 microgram), although there was a significant reduction in heart rate. When open field behavior was tested in conjunction with sexual behavior, ambulation and rearing were significantly decreased after beta-END treatment as compared with saline treatment. However, simple linear correlation tests showed a lack of correlation between the changes in open field behavior and the changes in sexual behavior, indicating that the effects of beta-END on the two types of behavior may be unrelated.(ABSTRACT TRUNCATED AT 250 WORDS)

Application of the theory of planned behavior to understand intentions to engage in physical and psychosocial health behaviors after cancer diagnosis.

A cancer diagnosis can trigger change in both lifestyle behaviors and mental health outcomes such as 'growth' and 'benefit-finding'. Assuming changes in mental health outcomes are based upon changes in specific behaviors, the Theory of Planned Behavior (TPB) may facilitate understanding of post-diagnosis change in physical and psychosocial 'health' behaviors. Adults (n = 130) < or =2 years post-cancer diagnosis completed an internet survey. Current performance and future behavior intentions for two physical (e.g. eating a healthy diet) and four psychosocial (e.g. spending quality time with family/friends; engaging in spiritual or religious activities) health behaviors were assessed. TPB constructs (subjective norm, behavior attitudes, perceived behavioral control) for each of the six behaviors were also assessed. Multiple regression analyses indicated the set of TPB constructs accounted for an increment of 25-53% of variance in behavioral intentions beyond that accounted for by clinical and demographic variables. Among individual TPB constructs, behavioral attitude was most consistently associated with behavioral intentions while subjective norm was least consistently associated with behavioral intentions. The TPB could serve as a comprehensive model for understanding change in both physical and psychosocial health behaviors after cancer diagnosis and could suggest innovative approaches to developing interventions to enhance post-diagnosis 'growth' and 'benefit finding'.

The prediction of safe lifting behavior: an application of the theory of planned behavior.

PROBLEM: Injuries resulting from lifting are costly, and create significant pain and discomfort. While engineering controls are the most effective means of reducing risks, most organizations continue to rely on manual lifting techniques. The problem, however, is that the use of safe-lifting techniques is inconsistent and managers have a difficult time motivating use of these techniques. Consequently, it is important to understand the factors driving safe-lifting behaviors. METHODS: This study used a survey to apply the theory of planned behavior (Ajzen., I., 1991. The theory of planned behavior. Organization Behavior and Human Processes, 50, 179-211) to safe-lifting among 136 materials management employees at a heavy manufacturing organization. Structural equation modeling and factor analysis were employed to analyze relationships among constructs. RESULTS: Results revealed that perceived behavioral control and intention were the strongest predictors of safe-lifting behavior. Subjective norms, to a lesser degree, were also important influences on intention. Attitudes did not surface as effective direct predictors of safe-lifting behavior, but did affect behavior and intent via mediating factors (subjective norms and perceived behavioral control). Finally, the theory of planned behavior was supported as an effective model explaining safe-lifting behavior, and had potential application for many other safety-related behaviors. IMPACT ON INDUSTRY: Results from this study emphasize the importance of perceived behavioral control as a factor associated with safety-related behavior.

Applying the theory of planned behavior to women's behavioral attitudes on and consumption of soy products.

OBJECTIVE: To identify variables that significantly predict the intention and behavior concerning soy consumption applying the Theory of Planned Behavior and to determine the role of race on women's perspectives and consumption behaviors concerning soy. DESIGN: Cross-sectional survey, with self-administered questionnaires. SETTING: City park service programs, community organizations, black cultural classes, and university offices. PARTICIPANTS: A convenience sample of 205 black (n = 103) and white (n = 102) women. VARIABLES MEASURED: Women's behavioral attitudes, subjective norms, perceived behavioral control, intention, and behavior related to soy consumption. ANALYSIS: Correlation and stepwise regression analysis. RESULTS: All variables in the Theory of Planned Behavior showed significant correlations with behavioral intention, with behavioral attitudes exhibiting the strongest correlation (r = .57, P < .01). Stepwise multiple regression analyses revealed that behavioral attitude toward taste and subjective norms accounted for 47.7% of the variance in behavioral intention. Behavioral attitude toward taste explained 48.6% of the variability in behavior. There was no difference between races for consumption or Theory of Planned Behavior variables. CONCLUSIONS AND IMPLICATIONS: A negative attitude toward the taste of soy was the major predictor for low soy consumption. However, future studies should be undertaken to verify this relationship once more women become aware of and have tasted soy.

Clinical behavior therapy and the experimental analysis of behavior.

Advances in areas of behavior analysis are discussed to show the relevance of experimental science to behavior therapy. It is concluded that there are many areas of mutual interest between experimental operant psychologists and behavior therapists that may serve to enhance the clinical efficacy and range of behavior problems addressed by behavior therapists. Specific examination is given to areas of experimental behavior analysis such as reinforcement, including schedules of reinforcement; the matching law; advanced issues in stimulus control; the interaction between operant and classical conditioning; behavioral momentum; rule-governed behavior; and stimulus equivalence. The argument that behavior therapists are not knowledgeable about behavior analysis is disputed, and it is concluded that behavior therapists are in a unique position to be the practice professionals best able to utilize the principles of learning and behavior analysis in the service of adaptive behavior change.

Accelerated nervous system development contributes to behavioral efficiency in the laboratory mouse: a behavioral review and theoretical proposal.

The emergence of the laboratory mouse as a favored species for genetic research has posed a number of problems for scientists interested in the reflection of genetic influences in mouse behavior. It is commonly thought that rat behavior, which has been studied more extensively than mouse behavior, could be easily generalized to mice. In this article, a number of categories of behavior displayed by the mouse (motor, spatial, defensive, social) are reviewed and contrasted with the same categories of behavior displayed by the rat. The comparison suggests that mouse behavior is simpler and more dependent upon elementary actions than the behavior of the rat. We suggest that the behavioral simplification in the mouse adapts it for a different ecological niche than that occupied by the rat. We propose that this simplification may be mediated by accelerated brain maturation during development. We further propose that this developmental acceleration in the mouse renders it less dependent upon complex social behavior and plastic nervous system changes associated with learning than the rat. This difference poses problems for the development of relevant methods of behavioral analysis and interpretation. Since the mouse's biological adaptations will be reflected in laboratory behavior, suggestions are made for behavioral approaches to the study and interpretation of mouse behavior.

Behavioral analysis and nursing interventions for reducing disruptive behaviors of patients with dementia.

In this study, two cases were used to examine the potential of behavioral analysis as an intervention to decrease disruptive behaviors of institutionalized individuals with dementia. Behavioral modeling was used to teach the principles of behavioral analysis. The nurses observed a behavior change plan implemented by the investigator, revised the plan based on behavioral analysis techniques, and subsequently implemented the revised behavioral strategies. The patients' disruptive behaviors decreased markedly when the behavioral intervention was implemented. Patients resumed disruptive behaviors when care was provided without the behavioral plan. The findings suggest the need to address interventions in nursing research, education, and practice that use behavioral analysis to reduce disruptive behaviors in individuals with dementia.

Compulsive-like behavior in individuals with Down syndrome: its relation to mental age level, adaptive and maladaptive behavior.

This study examined the nature of repetitive, ritualistic, and compulsive-like behaviors in 50 typically developing children and 50 individuals with Down syndrome (DS), matched on mental age (MA; M = 59.72 months). Parents reported on their children's compulsive-like behaviors-including ritualistic habits-and perfectionistic behaviors, as well as their children's adaptive and maladaptive behaviors. Results indicated that children with DS show similar MA-related changes in compulsive-like behaviors compared to the MA-matched comparison group. Younger children (both typical and DS) exhibited significantly more compulsive-like behaviors than older children. In general, children with and without DS did not differ from each other in terms of the number of compulsive-like behaviors they engaged in, although participants with DS engaged in more frequent, more intense repetitive behaviors. Compulsive-like behaviors were differentially related to adaptive and maladaptive behaviors across the MA and mental retardation groups. The results extend the "similar sequence" model of development to the construct of compulsive-like behaviors, and also suggest that some repetitive behaviors may be among the behavioral phenotype of individuals with DS.
