On the development of knowledge during problem solving

A person might solve a problem progressing very quickly after an initial period of very little progress, as if new insight was suddenly gained, without that person possessing anything that merits being called insight. This is demonstrated in a series of studies as an extension of the experiments of Kotovsky and Simon (1990). A total of 68 undergraduate students solved an isomorph of the Chinese Ring Puzzle. The first study showed that the verbal protocols of participants thinking aloud contained accumulating explicit knowledge. In the second study, the participants' move records were analysed in a novel way, and it was shown that the choices of moves gradually improved. In the third study the knowledge about the puzzle was tested after the puzzle was solved. The participants demonstrated that they knew, although imperfectly, which move was possible in a given situation. The fourth study showed that verbalising did not alter problem solving profoundly. Together, the four studies demonstrated that solving the puzzle took place after a gradual development of knowledge, instead of a flash of insight.     

The relative contributions of subjective and objective measures of body shape and size to body image and disordered eating in women

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR.     

Stress and Student Job Design: Satisfaction, Well-Being, and Performance in University Students

It is imperative that the university environment be supportive and capable of nurturing optimal learning and performance in students. Using job design and work stress theories, the study assessed relationships between psychosocial work characteristics, well-being and satisfaction, and performance in a random sample survey of Australian university students (N = 176). Methodological improvements were a time lag between survey and performance measures, an objective measure of performance, and LISREL structural equation modeling. Results showed high levels of psychological distress and low levels of satisfaction, both linked to high demands combined with low control. In accord with the happy-productive student hypothesis, satisfaction mediated the impact of the work environment on performance. Reengineering the design of the student work environment may therefore improve performance outcomes (student grades) through enhancing satisfaction.     

Collective Responsibility

The basic bearer of responsibility is individuals, because that isall there are – nothing else can literally be the bearer of fullresponsibility. Claims about group responsibility therefore needanalysis. This would be impossible if all actions must be understoodas ones that could be performed whether or not anyone else exists.Individuals often act by virtue of membership in certain groups;often such membership bears a causal role in our behavior, andsometimes people act deliberately in order to promote the prospectsof members of a given group. Nevertheless, it is rational to awardproportionally to individual contributions to those actions andindividual shares in the production of the consequences of thoseactions.     

Caregiver burnout among intimate partners of patients with a severe illness: An equity perspective

In the present study, caregiver burnout among the intimate partners of 106 cancer patients and 88 patients with multiple sclerosis was assessed. This study examined how burnout is related to marital quality and perceptions of inequity in the relationship. LISREL analyses showed that higher perceptions of inequity are strongly associated with higher emotional exhaustion and depersonalization, and lower feelings of personal accomplishment. Intimate partners of both cancer patients and patients with multiple sclerosis are relatively likely to experience burnout when they feel that they do not invest or benefit enough in the exchange with their ill partner. The relationship between inequity and burnout held when general marital quality, gender, the duration of the illness, the physical and psychological condition of the ill partner, and support from other persons were controlled for. This study shows that perceptions of equity or balance in the relationship between patients and their intimate partners are important for preventing caregiver burnout and for enhancing positive caregiver experiences.     

Improving Health Care Utilization, Improving Chronic Disease Utilization, Health Status, and Adjustment in Adolescents and Young Adults with Cystic Fibrosis: A Preliminary Report

We conducted a randomized clinical trial of a 3-session written self-disclosure intervention for patients with cystic fibrosis (CF). Patients (n = 39) who were at least 15 years of age and diagnosed with CF participated in the intervention. Participants in the intervention arm were asked to write in the health care setting about an important emotionally distressing issue of personal significance for a 20-min period of time and two additional 20-min writing episodes at the patient's home, which were prompted by telephone calls. Patients in the control condition received standard care alone. Findings revealed that the intervention resulted in a reduction of the number of days patients spent in the hospital over a 3-month period. The intervention did not have an impact on physiological (Forced Expiratory Volume and Body Mass Index or subjective markers of health status. These findings extend those of Pennebaker's (cf., J. Smyth, 1998) demonstrating an effect of the written-self-disclosure intervention on health care utilization. These preliminary findings are promising and justify further investigation of the modified intervention in other chronic illness populations.     

Study of the adjustment of Western expatriates in Taiwan ROC with the Multicultural Personality Questionnaire

The present paper examined the validity of the Multicultural Personality Questionnaire (MPQ). As criteria of validity three levels of adjustment were used. The study took place among a sample of expatriates ( N = 102) during their assignment in Taiwan. The MPQ has scales for cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. The MPQ scales appeared to be predictive of expatriates' personal, professional and social adjustment. In all three domains, emotional stability appeared most consistently as a predictor of adjustment. Social initiative was an additional strong predictor of psychological well-being, as was cultural empathy of satisfaction with life and of the amount of social support in the host country. Flexibility was a predictor of job satisfaction and social support. The study also examined the effects of marital status on adjustment. Married expatriates showed higher levels of adjustment than expatriates who were single or separated.
