The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Preattentive face processing: What do visual search experiments with schematic faces tell us? (2007, background): “A few other visual search studies tested positive and negative faces within neutral crowds (e.g., Eastwood et al., 2001; Williams et al., 2005).”
What we fear most: A developmental advantage for threat-relevant stimuli (2013, background): “Further, Williams et al. (2005) found that angry and happy faces are detected equally quickly, and more quickly than sad or fearful faces.”
Visual search of emotional faces: The role of affective content and featural distinctiveness (2009, methodology): “Gilboa-Schechtman et al. (1999) included three emotional expressions (happy, angry, and disgusted); Juth et al. (2005), another three (happy, angry, and fearful); and Williams et al. (2005), four (happy, angry, sad, and fearful).”
Young children with Autism Spectrum Disorder look differently at positive versus negative emotional faces (2008, background): “In light of evolutionary theories on the neurobiology of emotion (LeDoux, 1998), these findings may reflect heightened vigilance for threatening (social) situations ( Williams, Moss, Bradshaw, & Mattingley, 2005 ).”
The perception and categorisation of emotional stimuli: A review (2010, background): “Other studies report a search advantage both for angry and happy faces (Williams, Moss, Bradshaw, & Mattingley, 2005 ), or for happy compared to angry faces (Juth, Lundqvist, Karlsson, & Ohman, 2005 ).”
