Gender differences in factors affecting rejection of food in healthy young Swedish adults.

With the objectives to better understand gender-related differences in variables of importance for food intake, and interrelations between these variables, 100 healthy, young women and 100 healthy, young men responded to self-administrated questionnaires about general food rejection, learned illness-associated food aversions, disgust (the Disgust Scale), food neophobia (the Food Neophobia Scale), nausea and appetite. The results show that food rejection and aversions were more common in women (69 and 38%, respectively) than in men (47 and 18%), and that women are more disgust sensitive than men. However, no differences between women and men were observed regarding reasons for rejecting food (predominantly sensory attributes), prevalence of gastrointestinal illness as an associated aversion symptom (95 vs 89%), type of aversive food due to associated illness (predominantly high protein items), or food neophobia. Based on path analyses, a model is proposed of interrelations between disgust, food neophobia, learned food aversions, nausea, appetite, and general food rejection in healthy young adults.

Environmental influences on psychological restoration.

Research on psychological restoration and restorative environments is a needed complement to work on stress and environmental stressors. Two laboratory experiments tested the utility of two restorative environments theories, one concerned with directed attention capacity renewal and the other with stress reduction and associated changes in emotion. Various strategies were employed to distinguish restorative effects from other effects, to limit the role of arousal reduction in attentional restoration, and to begin mapping the time course for the emergence of outcomes. Both experiments tested for differential emotional and performance effects as a function of photographic environmental simulation (natural or urban environment). Across the experiments the natural environment simulation engendered generally more positive emotional self-reports. That consistent performance effects were not found in either study suggests that attentional restoration as reflected in performance is a more time-intensive process.

Hemisphere inactivation and mood-state changes.

Mood-state changes were studied during a sodium Amytal testing procedure in epilepsy patients with unilateral temporal lobe foci. The results showed that inactivation of the left hemisphere, but not the right hemisphere, produced a negative mood state. This decline in mood was not specifically related to side of focus or sex. As expected, the inactivation of either hemisphere also lead to an impairment in memory performance. This impairment was somewhat worse during a left than a right hemisphere inactivation. Furthermore, patients with left hemisphere foci showed a lower memory performance than patients with a right-hemisphere lesion. These results suggest (a) a hemispheric specialization for emotion that underlie changes in mood and (b) a discrepancy between mood states at encoding (during inactivation) and retrieval (after inactivation).

Psychological factors in orthognathic surgery.

27 patients subjected to various orthognathic surgery procedures were studied preoperatively and during a period of 18 months postoperatively by a team of psychologists to evaluate the patients' own opinions concerning the indication for surgery, information about the surgical procedure, the postoperative period and the long-term aesthetic and functional results. The patients were interviewed 5 times: 2 days before surgery, 2 days after surgery and 2, 6 and 18 months after surgery. The decision to undergo surgery was taken after a long period of time, 4 years on average, and half of the patients were influenced by their family or dentist before they made their decision. 60% gave three or more reasons for surgery, 85% mentioned functional problems, 74% facial appearance and 59% craniomandibular symptoms. 63% indicated that the facial appearance problems had negatively influenced their personal life and 44% their social life. Women experienced this problem more often than men. The results showed that the overall majority of patients were relieved of their presurgical problems. The aesthetic improvement was better than expected. It was found that improvements in facial features had a beneficial influence on the patients as individuals and also on their social life situation.
