Issue Information

PsyCh Journal's December issue opens with a special collection on chronobiology, the topic taking the 2017 Nobel Prize in Medicine, starting with an editorial introduction titled “Chronobiology—Circadian Oscillators in Neuroscience.” An original article then reports a suggested association between sleep length and depression in a large sample of Chinese adolescents, followed by review articles discussing research on the impacts of chronotype on education, and on interactions of the circadian system with the stress system which may include disruptions of the circadian clock by repeated psychosocial stress. Two short communications close out the collection with a report on the potential use of sleep‐time indices as a proxy for in‐lab melatonin measures of circadian phase, and a proposal for using chromatic pupillometry for testing the functionality of arousal‐promoting non‐visual effects of light in older adults. The December issue also includes an original article validating the Asian American Family Conflict Scale in a study among Chinese Americans, plus special reports examining the impact of characteristics of the urban environment on the way‐finding strategies of the blind, and a consideration of how problem‐oriented research might best be organized given the heuristic assumption of a world lacking universities as we know them. There are also short communications reporting an fMRI study showing different patterns for self‐serving and other‐serving decisions in a tempting‐decision task, and the results of a survey on the link between jealousy and relationship satisfaction among dating adults in Indonesia. A final contribution reports research results from China relevant to the question of whether neural markers can be identified for temporal segmentation in the domain of a few seconds.
