  "abstract": "<p>Individuals high in depressive symptom severity show probability bias: they believe negative&nbsp;events are relatively probable, and positive events relatively improbable, compared to those&nbsp;with less severe symptoms. However, this has only ever been demonstrated using self-report&nbsp;measures, in which participants explicitly estimate events&rsquo; probabilities: this leaves open the&nbsp;risk that &lsquo;probability bias&rsquo; is merely an artefact of response bias. We tested the veracity of&nbsp;probability bias using an indirect behavioural measure, based on a sentence-reading task.&nbsp;Study 1 tested 112 Turkish students; Study 2 tested 117 international users of online groups&nbsp;for people with depressive and anxiety disorders. As predicted, participants with higher&nbsp;depressive symptom scores responded relatively quickly to sentences stating negative events&nbsp;might occur, and relatively slowly to sentences stating positive events might occur, compared&nbsp;to those with lower scores. This effect was only marginal in Study 1, but reached significance&nbsp;in Study 2. However, contrary to predictions, this effect was not moderated by the probability&nbsp;level stated in the sentence. This makes our findings difficult to interpret, and we must&nbsp;present these studies as a failure to convincingly demonstrate depression-related probability&nbsp;bias. We hope this stimulates more work on the nature and veracity of probability bias.</p>",
