AbstractMicro-PK was explored in zebra finches (Taeniopygia guttata) to test the hypothesis of nondirectional REG randomness reduction during an alarm situation. A 15-s video clip of a crawling snake was presented to 80 participants and a REG's outcome during the presentation of the stimulus was analysed under three conditions: Bird Alone, Bird Plus Observer, and Observer Alone. One 200-bit trial was collected every quarter of a second during die presentation of the stimulus and the 5-min control period before die start of die disturbing stimulus, and the obtained cumulative chi-square deviation scores were analysed. The finding diat die scores during die stimulus period for die diree conditions belonged to the same population, their direction being die same when independently and globally analysed, togetiier with the nonsignificant difference with respect to their controls do not support die proposed hypotiiesis. However, an as yet undifferentiated psi observer effect is suggested by die global scores of die stimulus periods departing from chance while the scores of die corresponding controls did not, by die former's values surpassing die latter, and by die scores of die stimulus periods deviating from chance when die observer was present.
