[en] All living beings exhibit preferences for a variety of biologically significant stimuli. Interestingly, stimuli without biological significance, such as saccharine, are also able to induce preferences in vertebrates. Can invertebrates show preferences for biologically neutral cues as well – i.e. independently of any conditioning process? Experiment 1 aimed to determine the preference of woodlice (Porcellio scaber Latreille 1804) exposed to floor textures that differed in tactile cues, how they expressed their tactile preference, and whether they were able to inhibit that preference when a shelter of variable quality was available on the non-preferred floor texture. Experiment 2 provided additional information relative to the strength of woodlice’s tactile preference as well as the way of measuring it. Experiment 3 complemented the previous one in attempting to determine woodlice’s preference for regular versus random tactile cues. Taken together, the results suggest that (i) woodlice are able to process sensory information relative to biologically non-significant stimuli and (ii) that, because the motivation induced can interact with sheltering as a survival-related behavior, the processing of both types of motivation might depend on the same brain systems.
