Incidental learning of food and emotional words in women with anorexia nervosa.

Prior research suggests that anorexic patients show a memory bias for fattening foods when they are processed in depth or with reference to the self. The present study examined whether anorexic subjects exhibit a bias for fattening foods when these are presented as task-irrelevant distractor stimuli. It also investigated whether anorexic patients pay less attention to emotion stimuli. A sequential word-word evaluation task was administered to 11 inpatients with anorexia nervosa and 11 non-dieting normal subjects. There were four types of distractor words: high caloric foods, positive, negative, and neutral. Anorexic patients recalled no more food words but fewer neutral and positive words than normal subjects. The present data suggest that, compared to healthy young women, anorexic patients show no memory bias for fattening foods when these data are presented as peripheral environmental information. Anorexic patients are perceptually no less sensitive to negative emotional information than normal subjects.

20-Item Toronto Alexithymia Scale: do difficulties describing feelings assess proneness to shame instead of difficulties symbolizing emotions?

A hallmark of alexithymia is the difficulty putting emotional states into words which has to be differentiated from problems to communicate emotion to others. Shame proneness is a personality trait that is expected to be closely related to a reduced emotional self-disclosure in social interactions. The present investigation was conducted to examine construct validity of the Difficulties Describing Feelings scale of the 20-Item Toronto Alexithymia Scale (TAS-20). The TAS-20 was administered to 68 subjects (30 psychiatric inpatients and 38 normals) along with the Levels of Emotional Awareness Scale (LEAS), a direct measure of the ability to express feelings verbally, and the Shame-Guilt-Scale. Difficulties Describing Feelings was associated with shame assessing scales but not with guilt assessing scales or the LEAS. Thus, in view of our data one should be cautious in interpreting scores from the TAS-20 scale Difficulties Describing Feelings as indices of a difficulty to symbolize one's emotions. Instead, this TAS-20 scale seems to evaluate aspects of social shame.
