Costs of Suppressing Emotional Sound and Countereffects of a Mindfulness Induction: An Experimental Analog of Tinnitus ImpactHesser, Hugo, Molander, Peter, Jungermann, Mikael, Andersson, Gerhard January 2013 (has links)
Tinnitus is the experience of sounds without an appropriate external auditory source. These auditory sensations are intertwined with emotional and attentional processing. Drawing on theories of mental control, we predicted that suppressing an affectively negative sound mimicking the psychoacoustic features of tinnitus would result in decreased persistence in a mentally challenging task (mental arithmetic) that required participants to ignore the same sound, but that receiving a mindfulness exercise would reduce this effect. Normal hearing participants (N = 119) were instructed to suppress an affectively negative sound under cognitive load or were given no such instructions. Next, participants received either a mindfulness induction or an attention control task. Finally, all participants worked with mental arithmetic while exposed to the same sound. The length of time participants could persist in the second task served as the dependent variable. As hypothesized, results indicated that an auditory suppression rationale reduced time of persistence relative to no such rationale, and that a mindfulness induction counteracted this detrimental effect. The study may offer new insights into the mechanisms involved in the development of tinnitus interference. Implications are also discussed in the broader context of attention control strategies and the effects of emotional sound on task performance. The ironic processes of mental control may have an analog in the experience of sounds. / <p>On the day of the defence date the status of this article was <em>Manuscript</em>.</p>

Profiles of Everyday Thought SuppressionIe, Amanda Yen Lin 06 June 2014 (has links)
The present research assessed whether levels of depression, anxiety and worry, obsessive-compulsive distress, and psychopathy were differentially related to distinct thought suppression profiles. As a means to achieving this goal, the Profiles of Everyday Thought Suppression (PETS) scale was constructed to measure the frequencies with which various target thoughts are suppressed. The PETS scale demonstrated good internal consistency and test-retest reliability, and scores were positively correlated with the general tendency to experience intrusions, the general tendency to suppress thoughts, neuroticism, and health complaints. Although the proportions of time people suppress thoughts was positively associated with the frequencies with which the thoughts are experienced, the strength of the associations differed across thought contents, suggesting that not all frequently experienced thoughts are invariably subject to suppression attempts. The frequency with which thoughts are generally suppressed was positively associated with overall levels of subclinical psychopathology experienced during the past month. When comparing across the various thought categories, results from multiple analytic strategies converged to suggest that specific subclinical psychopathological states are associated with particular sets of thoughts that are frequently suppressed. / Psychology
