Persons scoring high on negative affectivity (NA) have more subjective heal
th complaints. In this study, we tested the hypothesis that high NA persons
are more likely to experience internal sensations as threatening signs of
health problems. Low and high NA participants (N = 44) were given four brea
thing trials: one room air trial followed by three trials containing 5.5% C
O2 which induced transient low intensity somatic sensations. Prior to each
CO2 trial, participants received either positive, negative or uncertain lab
elings of the sensations that might occur. Participants rated the (un)pleas
antness of the experienced somatic sensations and the perceived intensity.
Also respiratory responses were measured. During CO2 trials, reliable main
effects of information were found but no effects involving NA were observed
, neither on pleasantness ratings nor on respiratory responses. However, du
ring room air breathing, high NA participants reported more intense somatic
sensations than low NA participants. Post-experimental data suggested that
high NA participants had more negative meanings and worries about the cons
equences of the physical sensations. It is concluded that interpretational
biases in high NA is situated at the level of attributional processes.
