Past research on verbal deception has found inconsistent patterns, possibly due to failure to consider the dynamic nature of interpersonal deception. The current investigation examined temporal changes and sequencing effects in truthful and deceptive responding on 23 linguistic measures. Interviewees responded to 12 questions during which they alternated between giving blocks of truthful and blocks of deceptive answers. Results showed significant variability in verbal behavior across the course of the interviewon virtually all measures. Deceptive responding differed from truthful responding depending on the truth-deception sequence and the phase of the interview. The truth-first order made it much easier for deceivers to approximate truthful discourse sooner. The existence of significant variability due to time and sequence has important implications for identifying reliable indicators of deception and for research paradigms used to investigate deceptive and truthful discourse.

Background: Mainland China has experienced five epidemics of human cases of avian influenza A(H7N9) virus infection since 2013. We conducted a prospective study to assess long-term clinical, pulmonary function testing, and chest computed tomography (CT) imaging findings after patients were discharged from hospital. Methods: A(H7N9) survivors in five provinces and one municipality underwent follow-up visits from August 2013 to September 2018, at three, six, and 12 months after illness onset, and a subset was also assessed at 18 and 64 months after onset. Thirteen patients were enrolled from the first A(H7N9) epidemic in 2013, 36 from the 2013-2014 second epidemic, and 12 from the 2016-2017 fifth epidemic. At each visit, A(H7N9) survivors received a medical examination, including the mMRC (modified Medical Research Council) dyspnea scale assessment, chest auscultation, pulmonary function testing and chest CT scans. Findings: The median age of 61 A(H7N9) survivors was 50 years. The cumulative rate of pulmonary dysfunction was 38¢5% and 78¢2% for chest CT scan abnormalities at the end of follow-up. Restrictive ventilation dysfunction was common during follow-up. Mild dyspnea was documented at three to 12-month follow-up visits. Interpretation: Patients who survived severe illness from A(H7N9) virus infection had evidence of persistent lung damage and long-term pulmonary dysfunction.
