Aerobic cycle exercising in a rehabilitation program with a wider choice of intensity

When patients in rehabilitation programs use cycle ergometers for aerobic fitness training, the exercise intensity is often restricted to a small range of heart rate. In this study, a wider choice of intensities was left to the patients without giving up the potential to reduce cardiac risks factors. 24 patients in 3-wk. rehabilitation programs could choose the exercise intensity up to a workload limit preset by the physical therapist. 20 of them exercised at an intensity covering the full range between the aerobic and anaerobic lactate threshold and 4 a little above. The opportunity to vary the workload was frequently used by 67%. In 75% of the exercise sessions, the patients' average heart rates exceeded moderate heart-rate targets recommended in rehabilitation and health promotion for people with moderate cardiac risks without a graded exercise test. In 72% of these sessions, the anaerobic lactate threshold at 4 mmol/L was not exceeded. But a tendency of 33% of the patients to exercise at higher blood lactate or blood pressure levels underlined the necessity of limiting the exercise intensity.     

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.     

Facing prejudice: implicit prejudice and the perception of facial threat

We propose that social attitudes, and in particular implicit prejudice, bias people's perceptions of the facial emotion displayed by others. To test this hypothesis, we employed a facial emotion change-detection task in which European American participants detected the offset (Study 1) or onset (Study 2) of facial anger in both Black and White targets. Higher implicit (but not explicit) prejudice was associated with a greater readiness to perceive anger in Black faces, but neither explicit nor implicit prejudice predicted anger perceptions regarding similar White faces. This pattern indicates that European Americans high in implicit racial prejudice are biased to perceive threatening affect in Black but not White faces, suggesting that the deleterious effects of stereotypes may take hold extremely early in social interaction.     

Tell me where you come from and I know what makes you tick: Managing the consumer personality–satisfaction link in diverse cultures

Marketing programs that evoke high satisfaction and marketing success in one culture often fail in others, but the understanding of those cultural differences is insufficient. The question of how culture is linked to consumer satisfaction is still not answered satisfactorily. One promising paradigm for exploring such questions comes from progress in cross-cultural personality psychology. Thus, we examine the influence of individual-level cultural orientations on personality, and the role of personality and affect in satisfaction formation across cultures. Based on experimental data, we show that a high individualism orientation triggers higher levels of extraversion; a high uncertainty-avoidance orientation triggers higher levels of neuroticism. Based on field data from Japan, Spain, and the United States, we identify equivalent relationships amongst personality-related antecedent processes shaping satisfaction indicating universality across these cultures. The findings demonstrate the usefulness of cross-cultural personality psychology theory and methods for understanding and predicting consumer responses to marketing actions across cultures.     

Barriers to treatment success in behavioral consultation: Current limitations and future directions

Behavioral consultation is a prominent indirect service model in the practice of psychology in the schools. Despite some empirical support for the use of behavioral consultation strategies, consultants frequently face a number of barriers to implementation of treatment in practice. This article outlines a number of these barriers in behavioral consultation, including the lack of standardization of consultation, lack of specific training of consultants, little or no consultee (teacher) training, problems surrounding target behavior identification, and external constraints to consultation. Each of these areas is described along several dimensions that need to be addressed in future research.     

The operant control of vocalization in the dog

Control over the vocal responses of three dogs was established using operant-conditioning procedures. Several points of interest were observed in the data. First, fixed-ratio schedules of reinforcement generated a vocal response topography which was similar in detail to that of a “motor” bar-nosing response. Second, vocal responding was brought under the control of external visual stimuli as a result of differential reinforcement. Third, good stimulus control was maintained on a multiple schedule containing a vocal-response component and a bar-response component. Fourth, the stimulus control on the multiple schedule transferred with minimal disruption to a chain schedule requiring a sequence of 10 bar responses followed by 10 vocal responses. Fifth, because vocal and bar responses are not mutually exclusive, concurrent responding tended to develop on the chain schedule.

These results were discussed with reference to the advisability of applying the terms operant and respondent to unconditioned behavior, and, particularly, to unconditioned verbal behavior.

     

COMBINING STIMULUS FADING,REINFORCEMENT, AND EXTINCTION TO TREAT FOOD REFUSAL

The food refusal of a 6-year-old girl with destructive behavior was treated using stimulus fading, reinforcement, and escape extinction. Intake increased and compliance with prompting procedures remained relatively stable despite the increased consumption requirement.
