Older peoples' attitudes to mental illness.

Despite the prevalence of mental health problems in later life, older people markedly underutilize mental health services. A greater awareness of factors influencing older peoples' attitudes to mental illness may therefore improve awareness and treatment of mental disorders in this population. A mixed methodology approach was used to explore and compare older peoples' attitudes to mental illness in a sample of clinical and non-clinical participants. Results indicated that, similar to younger people, older people endorsed a range of positive and negative attitudes to mental illness. However, when attitudes to mental illness were considered within the context of ageing and experience a more complex pattern of results emerged. Although negative attitudes to mental illness were associated with negative attitudes to ageing across the entire sample, clinical participants (and those with prior experience of mental illness) reported more positive attitudes to mental illness and more negative attitudes to ageing than non-clinical participants, for whom the reverse was true. Attitudes were also differentially related to health behaviour outcomes. Results suggest that attitudes to mental illness and ageing may be linked and mediated by personal experience and capacity for psychological self-regulation in the face of age-associated adversity.

Perception of facial expressions of emotion in bipolar disorder.

OBJECTIVES: Some studies have reported deficits in the perception of facial expressions among depressed individuals compared with healthy controls, while others have reported negative biases in expression perception. We examined whether altered perception of emotion reflects an underlying trait-like effect in affective disorder by examining facial expression perception in euthymic bipolar patients. METHODS: Sensitivity to six different facial expressions, as well as accuracy of emotion recognition, was examined among 17 euthymic bipolar patients and 17 healthy controls using an interactive computer program. RESULTS: No differences were found between euthymic bipolar patients and controls in terms of sensitivity to any particular emotion. Although initial analysis of the data suggested impairment in the recognition of fear among the patients, identification of this emotion was not relatively impaired compared with that of the other emotions. CONCLUSIONS: The study did not find any conclusive evidence for trait-like deficits in the perception of facially conveyed emotions in bipolar disorder. Altered perception of facial expressions that has been found to accompany depressed mood may instead reflect mood-congruent biases.

Facial affect perception in alcoholics.

Satisfactory interpersonal interaction involves understanding others' facial expressions. Alcoholic individuals often have severe interpersonal difficulties that may relate to poor and distorted perception of facial expressions. The importance of attention direction has been highlighted by the finding, in recent primate studies, of neurons responsible for the detection of attention direction. Studies on humans suggest that expression perception is modulated by attention direction (whether the expression is directed towards or away from the observer). Here, for the first time, the relationship between attention direction and perception of expression (anger, sadness, happiness and disgust) in alcoholic and control subjects is investigated. We used animated facial stimuli depicting different emotions to give measures of recognition accuracy and of perceptual sensitivity. Our study demonstrated that alcoholics made more errors than control subjects in recognising expressions generally and had a tendency to mis-label sad expressions directed towards them as being hostile (angry/disgusted). When asked to select the point when they started to see the expression, alcoholics, especially female alcoholics, chose higher expression intensities. This study highlights the importance of investigating the modulating effects of attention direction when studying the perception of expressions and provides an indication of how alcoholics' inappropriate social reactions may be triggered.
