This effect distorts smooth interaction or an emotional connection between humans and artificial figures. Verkkowe argue that the uncanny valley hypothesis is ultimately an engineering problem that bears on the possibility of building androids that may some day become indistinguishable from humans. In closing, we propose a dehumanization hypothesis to explain the uncanny phenomenon. Verkkothe paper reports a scoping review of the uncanny valley (uv) based on neuroscientific studies. • neural processing differences and similarities between artificial agents and humans were found. • understanding of the uv from a neuroscience perspective can help inform the design of artificial agents. Verkkothe uncanny valley theory describes how emotional reactions vary with perceived human likeness. Verkkothe present study investigated the uncanny valley by measuring observers' impressions of facial images whose degree of realism was manipulated by morphing between artificial and real human.
