- The study is an experimental test of Hallam's habituation theory of tinnitus; this theory implies that the huge variation in suffering among individuals with about the same amount of tinnitus is due to differences in habituation to the perceived sound. Fourteen patients, seven 'complainers' and seven 'noncomplainers', participated in an experiment where we studied changes in skin conductance and heart rate responses to a series of tinnitus-like sound stimuli. No group differences in habituation were observed. We suggest that facilitatory processes, like disinhibition, may be more important than deficient habituation for the inability, in some individuals, to adapt to their tinnitus.

- Acquired hearing loss has frequently been reported to cause strains in everyday life, but few attempts have been reported where the affliction is related to the concept of stress. In this within-subjects investigation of 48 middle-aged to elderly hearing impaired patients, the relationships between hearing measurements, experienced disability and handicap (HMS), and psychological and somatic distress symptoms (SCL-90(R)) were analyzed. The variations in experienced hearing disability was found to correlate to the occurrence of a few, but more severe distress symptoms, and by loss of hearing for high frequencies. The experienced handicap, defined as emotional responses and personal opinions, was found to correlate to a general level of distress. In particular those distress items expressing insecurity were related to handicap experience. It was suggested that insecurity in social settings, and diminished hearing for contextual sounds, could cause a perceived loss of control, which could induce stress reactions.

- To determine the importance of emotional stress for relative polycythaemia, we studied 11 subjects with the Type A and 11 subjects with the Type B behaviour patterns during short-term mental stress. All subjects were healthy, normotensive non-smoking young males aged 20-34 yr. without any medication. During rest there were no significant differences in heart rate, blood pressure, or plasma catecholamines between the two groups, but the A-group had significantly higher haemoglobin concentration (147 vs 140 g/l; p less than 0.005) and haematocrit (43.8 vs 42.1%: p = 0.05) than the B-group. In the whole group, there was a positive correlation between resting diastolic blood pressure and haemoglobin concentration (r = 0.53; p less than 0.05). In response to 10 min of mental arithmetic, haematocrit, haemoglobin and erythrocyte count rose approximately 2% (p less than 0.001 throughout). The stress-induced changes were not significantly different between the A- and B-groups. It is concluded that mild relative polycythaemia could be induced by acute emotional stress. In subjects with the Type A behaviour pattern a slight haemoconcentration is present already at rest, which further increases during stress.
