Toward an animal model of type A behavior

Time estimation and dominance tests were used to differentiate the behavior of Mongolian gerbils to be analogous to Type A and Type B human behavior. Preliminary classification of animals as "Type A" or "B" was based upon differential performance on DRL 20-sec and DRL 60-sec reinforcement schedules. To retain their preliminary classification, Type A and Type B animals were required to be dominant and subordinate, respectively, in matches with each of three same-sex animals of opposite behavioral classification. Following classification, breeding pairs were constituted and classification procedures were repeated with two succeeding generations. Animals that exhibited Type A timing "won" significantly more dominance matches than did Type B animals. Incidence rates of Type A and Type B behavior in the two selectively bred generations were significantly greater than frequencies in the original stock generation. The usefulness of the present animal model for investigating the association of Type A behavior with coronary heart disease is discussed.     

A test of a disease-avoidance model of animal phobias

This study examined the relationship between disgust/contamination sensitivity and fear of animals. The results suggested that sensitivity to disgust and contamination was directly related to scores on the animal phobia and fear of illness and death sub-scales of the Fear Survey Schedule (FSS). Further analysis suggested that disgust/contamination sensitivity was related only to fear of certain groups of animals: namely those animals that are not considered to attack and harm human beings but are considered fear-evoking (e.g. rat, spider, cockroach), and those animals that are normally considered to evoke revulsion (e.g. maggot, snail, slug). Disgust/contamination sensitivity was not related to fear of animals that are considered highly likely to attack and harm human beings (e.g. tiger, lion, shark). These results are discussed as support for a disease-avoidance model of common animal fears.     

A Fishbein-Ajzen model of intention to work following childbirth

This research identifies factors which influence college women's intention to work during the first 3 years following childbirth. It uses a model, derived from M. Fishbein and I. Ajzen (1975, Belief, attitude, intention, and behavior, Reading, MA, Addison-Wesley) as modified by P. M. Bentler and G. Speckart (1979, Psychological Review, 86, 452–464), which proposes that intentions are a function of own work experience, vicarious experience with a working mother, subjective normative pressure, and attitudes. Data collected via a mailed questionnaire from 202 white women and analyzed using maximum likelihood estimation of structural equation parameters supported the fit of the model. Attitudes had the strongest influence on intentions.     

A laboratory model for evaluating relapse of undesirable caregiver behavior

The success of behavioral treatments like functional communication training depends on their continued implementation outside of the clinical context, where failures in caregiver treatment adherence can lead to the relapse of destructive behavior. In the present study, we developed a laboratory model for evaluating the relapse of undesirable caregiver behavior that simulates two common sources of disruption (i.e., changes in context and in treatment efficacy) believed to affect caregiver treatment adherence using simulated confederate destructive behavior. In Phase 1, the caregiver's delivery of reinforcers for destructive behavior terminated confederate destructive behavior in a home‐like context. In Phase 2, the caregiver implemented functional communication training in a clinical context in which providing reinforcers for destructive or alternative behavior terminated confederate destructive behavior. In Phase 3, the caregiver returned to the home‐like context, and caregiver behavior produced no effect on confederate destructive or alternative behavior, simulating an inconsolable child. Undesirable caregiver behavior relapsed in three of four treatment‐adherence challenges.     

An animal model of fetishism

An animal model of sexual fetishism was developed with male Japanese quail based on persistence of conditioned sexual responding during extinction to an inanimate object made of terrycloth (Experiments 1 and 3). This persistent responding occurred only in subjects that came to copulate with the terrycloth object, suggesting that the copulatory behavior served to maintain the fetishistic behavior. Sexual conditioning was carried out by pairing a conditioned stimulus (CS) with the opportunity to copulate with a female (the unconditioned stimulus or US). Copulation with the CS object and persistent responding did not develop if the CS was a light (Experiment 1) or if conditioning was carried out with a food US (Experiment 2). In addition, subjects that showed persistence in responding to the terrycloth CS did not persist in their responding to a light CS (Experiment 3). The results are consistent with the hypothesis that conditioned copulatory behavior creates a form of self-maintenance that leads to persistent responding to an inanimate object. The development of an animal model of such fetishistic behavior should facilitate experimental analysis of the phenomenon.     

Local patterns in human operant behavior and a behaving model to interrelate animal and human performances

College students pressed buttons for points delivered according to molecular concurrent reinforcement contingencies similar to those used in previous experiments with animal subjects. Relative frequency of reinforcement and the relative and absolute durations of two reinforced patterns of button pressing were experimentally varied. Qualitative effects of all three variables resembled those obtained previously with animals. Computer simulation of a cognitive processing model described these qualitative effects. A similar model was used previously to describe corresponding behavior in pigeons. Therefore, similar cognitive processing may underlie the local temporal patterning of animal and human operant behavior maintained by this concurrent reinforcement contingency.     

A discriminated rapid-acquisition laboratory procedure for human continuous choice

Previous continuous choice laboratory procedures for human participants are either prohibitively time-intensive or result in inadequate fits of the generalized matching law (GML). We developed a rapid-acquisition laboratory procedure (Procedure for Rapidly Establishing Steady-State Behavior, or PRESS-B) for studying human continuous choice that reduces participant burden and produces data that is well-described by the GML. To test the procedure, 27 human participants were exposed to 9 independent concurrent random-interval random-interval reinforcement schedules over the course of a single, 37-min session. Fits of the GML to the participants' data accounted for large proportions of variance (median R²: 0.94), with parameter estimates that were similar to those previously found in human continuous choice studies [median a: 0.67; median log(b): -0.02]. In summary, PRESS-B generates human continuous choice behavior in the laboratory that conforms to the GML with limited experimental duration.     

Traumatic stress at work: A public health model

The emergence of the 'New Public Health' movement provides a framework for an integrated and co-ordinated policy for responding to traumatic stress in the workplace. A review of the clinical literature on post-traumatic stress reveals that the components of this framework are available: the challenge is to put in place all the various elements. An organisational response is described which tries to use primary, secondary and tertiary prevention strategies to reduce the impact of traumatic incidents-in this case, armed robberies-on employees of a financial services company. Inter-departmental working, appropriate use of management and social support, pre-trauma training and cognitive-behavioural counselling techniques are all used in an attempt to tailor support to the individual's own needs. Binding the process together is a simple psychological health screening process, offering as a by-product information to improve the responsiveness of the service.     

A model for judgments of work values and job satisfaction

First, a discussion is presented of some previous research results on the relation of a person's assessment of the importance ("value") of an object and his or her attitude toward that object, in particular on the relation of work values with job satisfaction. Then, a model is formulated and simulated to explain how both types of judgments are generated. In Phase 1, the elements of the mental representation of the respective attitude object are aggregated by two composition rules to an overall satisfaction and an overall importance judgment, respectively. In addition, possible dissonance of high importance and low satisfaction is reduced by a coping function.     

Prevention of the development of problem behavior: A laboratory model

Few studies have isolated the preventive efficacy of common behavioral strategies like noncontingent reinforcement (NCR) and differential reinforcement of alternative behavior (DRA). The purpose of the current study was to develop and evaluate a laboratory model of these two problem behavior prevention strategies. Undergraduate students participated in a computer simulation, in which clicks to a designated area of the computer screen were analogous to the emergence of problem behavior. The responding of participants in a control group, who experienced a percentile schedule used to mimic the shaping of problem behavior, was compared to that of participants in two experimental groups, each with a history of either DRA or NCR. Between‐subjects group comparisons showed that both intervention strategies were equally effective in the prevention of our analog to problem behavior when compared to the control group. The strengths and limitations of a laboratory model for prevention are discussed in light of recent applied work in this area.     

A causal model of burnout among self-managed work team members

The findings on burnout that are almost universally from research in service settings are applied to an industrial setting with self-managed work teams. Researchers formulated several hypotheses on the basis of this literature. These hypotheses were then used to develop a structural (causal) model that was tested and refined using LISREL 8. Data were collected from 320 employees concerning perceptions of several job and organization conditions, as well as the three components of burnout. Results indicated that role conflict contributed to emotional exhaustion, and participation in work teams diminished it. Job ambiguity, low co-worker support, and low job ability contributed to feelings of low personal accomplishment. These results were consistent with previous findings. When insufficient time to complete a job was removed from the workload measures, workload actually diminished burnout, a finding opposite from previous research. Other organization factors had no significant impact on burnout in this setting.     

A progressive model for teaching children with autism to follow gaze shift

Gunby, Rapp, Bottoni, Marchese and Wu (2017) taught three children with autism spectrum disorder to follow an instructor's gaze shift to select a specific item; however, Gunby et al. used different types of prompts with each participant. To address this limitation, we used a progressive training model for increasing gaze shift for three children with autism spectrum disorder. Results show that each participant learned to follow an adult's shift in gaze to make a correct selection. In addition, two participants displayed the skill in response to a parent's gaze shift and with only social consequences; however, the third participant required verbal instruction and tangible reinforcement to demonstrate the skill outside of training sessions.     

The muskrat (Ondatra zibethicus) as a laboratory animal

Methods for the capture, maintenance, taming, and behavioral testing of wild-born muskrats(Ondatra zibethicus) are described. The muskrat is simple and inexpensive to maintain in the laboratory and seems suitable for behavioral research.
