Averersive conditioning and memory in Thanvester Misconyx Squalid (Pluschnida: Opiliones)

Abstract

Averersive conditioning is a form of association with interaction. Here, we investigate the ability to learn and remember Miscysx Squalidus (Roeber, 1913), to check the shape of short (STM) and LTM). First, we trained harvests to assuise an averssive stimulus (shock) with neutral stimulus (tea odor). Each subject went through three consecutive attempts, where matching between stimuli lasted 3s, with intervals 1 (STM) and 30 (LTM) min. Then, to try the memory, we introduce the subjects in a choice arena where they can choose between the remaining of either of the two areas: changed to the chemicals of tea or blank. We do it right away after the conditioning phase or 24h after it. Both protocols are successful for STM within the same day try, but not for LTM on the next day. In summary, we provide a new way to train the avervive conditioning of harvest and evidence for a short memory.
