P-1B-35 文脈に対する凶器の特異性が凶器注目効果に及ぼす影響(2001年度 日本基礎心理学会第20回大会優秀発表賞)

抄録

The present study was designed to investigate the relationship between a weapon focus and a physical feature of a weapon, that is, whether a sharp knife attracts more attention than a not-sharp knife. Sixty participants watched a cooking scene depicted in pictures where a woman held one of three items: a sharp knife, a not-sharp knife, or a detergent spray. A weapon focus effect was measured as recognition of the central information related to the knife or spray. In the three conditions recognition of the central information was better for the sharp knife condition than for the other conditions. This result suggests that a weapon focus can be produced by the sharpness of a knife.
