The consequences of loneliness include anxiety, depression, and chronic illnesses, but little is known about its association with cognitive distortions. Three experiments investigated the effect of loneliness, and current context, on the content of false perceptions. A total of 446 participants completed psychometric tests (University of California, Los Angeles Loneliness Scale, Hospital Anxiety and Depression Scale, and a Schizotypy Scale) and a word detection task. The word detection task explored the effects of "lonely" and "neutral" contexts (experiments 1 and 2), as well as "positive social" contexts (experiment 3), on false perceptions. In all experiments, participants reporting higher loneliness reported more false perceptions with a lonely content, but only when in a context reflecting a lonely theme. The results show current environmental context and individuals' psychological state combine to affect false perception content. That such findings are found with loneliness, when controlling for depression, anxiety, and schizotypy, show the degree to which this state can distort cognition and perception.
