OBJECTIVE: Referring to the alexithymia construct and Bruch's clinical observations, this study investigated the ability to decode nonverbal signs of emotion in obese boys and girls, and their mothers. METHOD: A group of 10 boys and 11 girls with obesity and their mothers, and a control group were tested. Both mothers and children were asked to recognize a set of 32 brief film sequences interpreted by four actors expressing four emotions (anger, sadness, fear, happiness) with two intensity levels. Each sequence was presented first without sound, second without video, and finally with video and sound. RESULTS: As expected, boys and girls suffering from obesity and their mothers showed a reduced ability to decode visual and verbal signs of emotion compared to the control group. DISCUSSION: This result may be interpreted in accordance with the alexithymia construct, and suggests the importance of developing therapeutic strategies to face alexithymic characteristics in obese children and their mothers.
Twenty women underwent ultrasound examination three times during low-risk pregnancy. Before and after ultrasonography, the Symptom Questionnaire was applied to evaluate changes in psychological distress. Anxiety, depression, somatic symptoms, and hostility significantly decreased after the patients received video and verbal feedback during the first ultrasound examination. Such changes were consistently observed also during the subsequent two examinations.
The effect of an aversive, high-arousing film on heart rate, respiratory sinus arrhythmia, and electrogastrographic activity (EGG) was investigated. Previous studies have indicated a larger heart-rate deceleration for visual stimuli depicting surgery or blood compared to neutral content, and this phenomenon is similar to the bradycardia observed in animals in response to fear. The heart-rate deceleration is clearly parasympathetically driven, and it is considered a general index of attention. An accurate index of cardiac vagal tone can be obtained by means of quantification of the amplitude of respiratory sinus arrhythmia. The relationship between cardiac vagal tone and EGG is complex, but animal research has shown that suppressing vagal activity dampens gastric motility. We have investigated whether a movie depicting surgery is associated with greater heart-rate deceleration, larger increase in respiratory sinus arrhythmia, and greater increase in EGG activity compared to a neutral movie. In addition, if both respiratory sinus arrhythmia and EGG are indices of vagal tone, a positive correlation between these physiological responses was expected. Analysis indicated an effect of the surgery movie on heart rate and respiratory sinus arrhythmia, but not on EGG activity. Moreover, the expected correlation was not found. Implications for future studies are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
