--- abstract: "The study investigated the effects of perceptual load on the bias to report seeing non-existing events—a bias associated with positive symptoms of schizophrenia and positive schizotypal symptoms. Undergraduate students completed psychometric measures of schizotypy and were asked to detect fast moving words among non-words under different levels of perceptual load. Perceptual load was manipulated through stimulus motion. Overall, the results showed that the higher the perceptual load, the stronger the bias to report seeing words in non-word trials. However, the observed bias was associated with positive schizotypy (Unusual Experiences) only when visual detection was performed under conditions of medium perceptual load. \r\nNo schizotypy measure was associated with accuracy. The results suggest that, although some amount of perceptual ambiguity seems to be necessary for schizotypal bias generation, an increase in the perceptual load can inhibit this process possibly by preventing perception of task-irrelevant internal events, such as loose word associations. \r\n\r\n" altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Tsakanikos given: Elias honourific: '' lineage: '' date: 2006 date_type: published datestamp: 2008-11-23 09:31:47 department: ~ dir: disk0/00/00/62/70 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 6270 fileinfo: /style/images/fileicons/application_pdf.png;/6270/1/Tsakanikos_Perceptual_biases_%26_schizotypy_PAID_2006b.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2011-03-11 08:57:16 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: Personality and Individual Differences publisher: ~ refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 20 series: ~ source: ~ status_changed: 2008-11-23 09:31:47 subjects: - clin-psy succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: 'Perceptual biases and positive schizotypy: The role of perceptual load' type: journalp userid: 5051 volume: ~
