Does humor facilitate coping with physical discomfort?

The mediation of superior coping with physical discomfort after humorous stimulation was explored through respondents' exposure to materials varying markedly in their capacity to evoke amusement and joviality. Both male and female respondents were exposed to (a) stand-up comedy, (b) situation comedy, (c) serious drama, (d) instructional material, or (e) tragedy. Discomfort threshold for cuff pressure at the upper arm was ascertained prior to and following exposure. Cognitive and affective responses to the materials were recorded after the postexposure threshold measurement. Compared against exposure to instructional material in the control condition, and compared against pre-exposure threshold measures, exposure to either type of comedy and, unexpectedly, to tragedy significantly elevated the threshold for physical discomfort in both male and female respondents. Serious drama had no such effect. Taken together, the exposure effects on the discomfort threshold could not be attributed to amusement reactions. Nor could they be considered mediated by responses of positive hedonic quality during and after exposure. There was some indication, however, that the capacity of stimuli to evoke humorous reactions (material being deemed funny) and the absorption potential of stimuli (material being deemed captivating) were positively involved in the mediation of postexposure tolerance of physical discomfort.The authors would like to thank Charles Aust, Rahul Biswas, Ted Jones, and John Owens for their assistance in the data collection and in the planning of this investigation.     

Age and sex differences in health habits and beliefs of schoolchildren

All children in Grades 3 through 12 of one school system completed a survey about health habits and beliefs including smoking and eating habits, perceptions of exercise, weight, and parental involvement in health. The surveys were factor-analyzed within grade and sex, and the overall factors that emerged were Smoking Habits, Family Discussion of Health, Family Thinking About Health, Nutritional Habits, and Health Locus of Control. Analysis of variance of each factor revealed that girls generally reported healthier food habits than did boys. However, girls reported more smoking and less exercise. There are also changes in habits and belief with age; junior high school is a particularly important time for the development of several habits. The findings are discussed in relation to theories of child development and the implications for the content and timing of future health education intervention programs with children.     

A COMPONENT ANALYSIS OF FUNCTIONAL COMMUNICATION TRAINING ACROSS THREE TOPOGRAPHIES OF SEVERE BEHAVIOR PROBLEMS

We evaluated the separate treatment components of a functional communication training program for 3 severely handicapped persons who each displayed different topographies of aberrant behavior. Following a functional analysis of maintaining conditions for inappropriate behavior (self-injury, stereotypy, aggression), each participant was trained to emit a communicative response that functioned to solicit reinforcement. For 2 participants, consequences (time-out or graduated guidance) for inappropriate behavior were also included. Treatment continued until the participants emitted the communicative response independently and no occurrences of inappropriate behavior were observed for at least two sessions. Following treatment, the separate contributions of the treatment components for communicative responding and for inappropriate behavior were evaluated with a reversal design. The results indicated that both sets of treatment components were necessary for maximal control over aberrant behavior. These results are discussed in relation to the efficiency, history, and control over reinforcement of both appropriate and inappropriate responses.     

Natural Disaster and Risk of Psychiatric Disorders in Puerto Rican Children

We examined the persistence of psychiatric disorders at approximately 18 and 30 months after a hurricane among a random sample of the child and adolescent population (4–17 years) of Puerto Rico. Data were obtained from caretaker-child dyads (N = 1,886) through in person interviews with primary caretakers (all children) and youth (11–17 years) using the Diagnostic Interview Schedule for Children IV in Spanish. Logistic regressions, controlling for sociodemographic variables, were used to study the relation between disaster exposure and internalizing, externalizing, or any disorder. Children’s disaster-related distress manifested as internalizing disorders, rather than as externalizing disorders at 18 months post-disaster. At 30 months, there was no longer a significant difference in rates of disorder between hurricane-exposed and non-exposed youth. Results were similar across age ranges. Rates of specific internalizing disorders between exposed and unexposed children are provided. Research and clinical implications are discussed.     

The basis of shared intentions in human and robot cognition

There is a fundamental difference between robots that are equipped with sensory, motor and cognitive capabilities, vs. simulations or non-embodied cognitive systems. Via their perceptual and motor capabilities, these robotic systems can interact with humans in an increasingly more “natural” way, physically interacting with shared objects in cooperative action settings. Indeed, such cognitive robotic systems provide a unique opportunity to developmental psychologists for implementing their theories and testing their hypotheses on systems that are becoming increasingly “at home” in the sensory--motor and social worlds, where such hypotheses are relevant. The current research is the result of interaction between research in computational neuroscience and robotics on the one hand, and developmental psychology on the other. One of the key findings in the developmental psychology context is that with respect to other primates, humans appear to have a unique ability and motivation to share goals and intentions with others. This ability is expressed in cooperative behavior very early in life, and appears to be the basis for subsequent development of social cognition. Here we attempt to identify a set of core functional elements of cooperative behavior and the corresponding shared intentional representations. We then begin to specify how these capabilities can be implemented in a robotic system, the Cooperator, and tested in human–robot interaction experiments. Based on the results of these experiments we discuss the mutual benefit for both fields of the interaction between robotics and developmental psychology.     

Differences in cognitive processes underlying the collaborative activities of children and chimpanzees

We compared the performance of 3- and 5-year-old children with that of chimpanzees in two tasks requiring collaboration via complementary roles. In both tasks, children and chimpanzees were able to coordinate two complementary roles with peers and solve the problem cooperatively. This is the first experimental demonstration of the coordination of complementary roles in chimpanzees. In the second task, neither species was skillful at waiting for a partner to be positioned appropriately before beginning (although children did hesitate significantly longer when the partner was absent). The main difference between species in both tasks was in children's, but not chimpanzees’, ability to profit from experience as a collaborator in one role when later reversing roles. This difference suggests that as they participate in a collaboration, young children integrate both roles into a single “birds-eye-view” representational format in a way that chimpanzees do not.
