Effects of "Dirty" Information on Disgust Responding to an Unknown Animal in Children: The Moderating Role of Maternal Disgust Proneness

Although research has shown that disgust facilitates avoidance of small animals among adults, much less is known about disgust appraisals of small animals in children as well as the predictors of such appraisals. To address this gap, children (ages 5–13) were exposed to dirt-related and cleanliness-related information about unknown animals. The extent to which these types of information influenced children's feelings of fear, disgust, positivity, and avoidance behavior in relation to the animals was examined. The present study then examined the extent to which child and maternal disgust proneness predicted feelings of disgust to the ‘dirty’ animal. The findings show that providing dirt-related information resulted in a significant increase in disgust, but not fear, responding to the animal. Dirt-related information also resulted in a significant decrease in positive feelings toward the animal. Conversely, providing cleanliness-related information resulted in a significant decrease in disgust, but not fear, responding to the animal. In addition, providing cleanliness-related information resulted in a significant increase in positive feelings toward the animal. Children also engage in more avoidance of the animal described as dirty compared to the animal described as clean. In addition, subsequent analysis revealed an interaction between child and maternal disgust propensity in predicting learned disgust to the dirty animal such that the highest levels of feelings of disgust to the dirty animal were observed among children with high disgust proneness who also have mothers with high disgust proneness. The implications of these findings for conceptualizing the role of disgust in animal phobias among youth will be discussed.     

Number Use at Home by Children and Their Parents and Its Relationship to Early Mathematical Performance

The purpose of this research was to measure the frequency and variety of number activities occurring in the homes of pre-school and kindergarten children and to determine if there was a relationship between those activities and the children's mathematical performance. In two studies, parents were interviewed over the telephone and asked how often their child or they and their child had engaged in each of 33 number-related activities over the last week. Both studies found considerable variability in the frequency and type of number activities that children participated in at home. There was a positive correlation between the frequency of number activities that parents reported for their children and parental participation in the same activities. In addition, in study 2, parental reports of children's number activities at home were predictive of children's performance on a standardized test of early mathematical ability.     

Self-Report Versus Performance-Based Activities of Daily Living Capacity Among Heart Transplant Candidates and Their Caregivers

Transplant candidates completed the Every Day Problems test (EPT), a performance-based measure of instrumental activities of daily living (IADL), and the Katz self-report scale of IADL functioning. Caregivers estimated the candidate's IADL capacity using the Katz scale. A healthy community group and patients with cardiac disease not undergoing transplant evaluation and their caregivers served as controls. Discrepancies between the EPT and Katz scales were generated. Results showed that the total number of discrepancies was significantly higher among the two patient groups as compared to controls. Three or more discrepancies (a total of 7 IADL domains were assessed) occurred in 40–52% of the participants and their caregivers in the two patient groups. Similarly, the total number of discrepancies between the Katz scale of the participant and their caregiver was significantly higher among the two patient groups as compared to controls, with only 33–44% showing perfect agreement in the patient groups as compared to 97% among controls. Despite a high prevalence of discrepancies in both patient groups, results did not support the hypothesis that transplant candidates tend systematically to overestimate their ability level on self-report IADL measures.     

Analysis and treatment of finger sucking

We analyzed and treated the finger sucking of 2 developmentally typical children aged 7 and 10 years. The functional analysis revealed that the finger sucking of both children was exhibited primarily during alone conditions, suggesting that the behavior was maintained by automatic reinforcement. An extended analysis provided support for this hypothesis and demonstrated that attenuation of stimulation produced by the finger sucking resulted in behavior reductions for both children. Treatment consisted of having each child wear a glove on the relevant hand during periods when he or she was alone. Use of the glove produced zero levels of finger sucking for 1 participant, whereas only moderate reductions were obtained for the other. Subsequently, an awareness enhancement device was used that produced an immediate reduction in finger sucking.     

Providing independent recreational activities to reduce stereotypic vocalizations in chronic schizophrenics.

We evaluated the effects of minimally supervised, independent recreational activities on stereotypic vocal behavior in two chronic schizophrenic patients. In baseline sessions, subjects were observed during unstructured free time in the psychiatric ward. In treatment sessions, therapists presented preferred recreational materials (magazines, models, and art projects), verbally prompted on-task behavior every 20 min, and, in one condition, administered contingent tokens. Independent recreational activities reduced medium-rate self-talk in one subject and high-rate mumbling in a second subject by 60%-70%. Results were the same with or without contingent tokens. Apparent self-maintaining characteristics of these vocal responses are discussed.     

TEACHING BETWEEN-CLASS generalization OF TOY PLAY BEHAVIOR TO HANDICAPPED CHILDREN

In this study, young children with severe and moderate handicaps were taught to generalize play responses. A multiple baseline across responses design, replicated with four children, was used to assessthe effects of generalization training within four sets of toys on generalization to untrained toys from four other sets. The responses taught were unique for each set of toys. Acrossthe four participants, training to generalize within-toy sets resulted in complete between-class generalization in 11 sets, partial generalization in 3 sets, and no generalization in 2 sets. No generalization occurred to another class of toys that differed fromthe previous sets in that they produced a reaction tothe play movement (e.g., pianos). Implications for conducting research using strategies based on class interrelationships in training contexts are discussed.     

Determinants of everyday time allocation

Two experiments examined the role of intentions in people's allocation of time to everyday activities (e.g., talcing a shower, running for exercise). In Experiment 1 32 subjects rated their intentions of, preferences for, and perceived control over performance of 10 activities at different frequencies during the following month. In Experiment 2 another 36 subjects performed the same ratings for the following week, then returned after that week to report how frequently they had been engaged in the activities. The results of both experiments showed that either the ratings of preference, of perceived control, or both combined linearly, predicted the intentions. However, intentions did not predict performance particularly well. This probably reflected (1) that some activities are performed routinely without intentions being formed; (2) that intentions to perform some other, more impulsively timed activities are formed late when appropriate actual situations are encountered; and (3) that for still other activities intentions are formed but not maintained.     

The uses of mental imagery in athletics: An overview

This article surveys the extant literature on mental imagery as used in athletics for performance enhancement, arousal regulation, affective and cognitive modification, and rehabilitation. For each category of use, applications are discussed, an overview of the empirical and case-study research findings is presented, and the research is critiqued. A concluding section recommends directions for future research on uses of mental imagery in athletics.     

Discriminated response and incentive processes in operant conditioning: a two-factor model of stimulus control

Understanding stimulus control generated in instrumental learning requires the direct investigation of discriminated response and reinforcer (incentive) processes acquired exclusively through the response-reinforcer contingencies operating on complex (multicomponent) baselines. Two series of stimulus-compounding studies accomplished this direct investigation. In one series, the independent variable was the relative reinforcement between schedule components; in the second series, it was relative response rate between components. Stimulus-compounding tests revealed that response and incentive processes enhanced each other when in agreement, counteracted each other when in opposition, and produced intermediate results when only one factor was operating. This pattern of results led to the conclusion that these factors were algebraically combining and to the development of a response/incentive matrix reflecting these dynamics. This two-factor analysis was extended to the peak-shift effect in stimulus generalization experiments and to the generation of inhibitory control. Two decades of stimulus compounding and peak-shift research were organized within this two-factor framework, extending this traditional approach to learning to active research areas heretofore not systematically considered in these terms.
