与同种动物的社会互动会影响暴露动物的大脑发育和行为。这种体验可能涉及视觉、化学、听觉和触觉信号的交换和保留。当几个果蝇黑腹雄蝇与交配的女性在食物的存在下，他们表现出频繁的侵略性的相互作用。为了测量社会经验对雄性-雄性互动的作用，在没有雌性和食物的情况下，两个测试雄性在其成年发育的可变时期内天真或暴露于兄弟姐妹。这两个男性表现出同性恋求爱和攻击行为，频率，强度和方向根据他们的经验而变化。社会经验的影响大大增强部分缺陷的信息素感知的转基因雄性之间，表明男性抑制性信息素通常用于抑制雄性-雄性互动。
Social interaction with conspecifics can influence the developing brain and behaviour of the exposed animal. This experience can involve the exchange and retention of visual, chemical, acoustic and tactile signals. When several Drosophila melanogaster male flies are associated with mated females in the presence of food, they show frequent aggressive interactions. To measure the role of social experience on male-male interaction, two tester males naive or exposed to sibling(s) during a variable period of their adult development - were confronted in the absence of female and food. The two males displayed homosexual courtship and aggressive behaviours, the frequency, intensity and directionality of which varied according to their experience. The effect of social experience was greatly enhanced between transgenic males partially defective for pheromonal perception, indicating that male inhibitory pheromones are normally used to repress male-male interaction.
