1 ISCP2010 Symposium 1: What is animal intelligence? - Ability to generate novel adaptive behavior in humans and animals - Tohru Moriyama, Masao Migita, Shin Maruyama, Nobuhiro Furuyama

2 1. Timetable Presentations 10:10-10:30 Tohru Moriyama (Pill bug) 10:30-10:50 Masao Migita (Starfish) 10:50-11:10 Shin Maruyama (Human) Discussion and Questions 11:10-11:30 Nobuhiro Furuyama

3 Problem-solving experiment: good method. Animal that can solve problem also solved by human cannot always be called intelligent. 2. Problem

4 Pill bug, Armadillidium vulgare, Isopoda, Crustacea

5 “Thinking” “Mechanical process” Different mechanisms Pill bug

6 Fast Slow Fast Mechanical process: Bilaterally asymmetrical leg movement (BALM) (Hughes, Anim. Learn. Behav., 1985) 3.Mechanical process and conventional adaptive behavior in pill bugs Conventional adaptive behavior: Turn alternation (Kupfermann, Anim. Behav., 1966)

7 How can we determine intelligence in such mechanical animals? 4. Question

8 5. Answer Setting unfamiliar situation

9 6. Elicitation of novel adaptive behavior Novel detouring Sensing of wall’s texture (Moriyama, Int’l. J. Comp. Psychol., 1999)

10 7.Mechanism of elicitation of novel adaptive behaviors Leg movements etc. Choose Ignore Stimuli sensed Pill bug Autonomous choice of stimuli Leg movements Others Choose Ignore Stimuli sensed Pill bug Wall’s texture Unfamiliar situation Wall’s texture

11 a, b, c, ・・・ β, γ, ・・ ・ Choose Ignore Stimuli sensed Human or animals Autonomous choice of stimuli α 8.Autonomous choice of stimuli: common mechanism for “us” Capacity

12 In consecutive T-maze (unfamiliar situation)

13 Common mechanism Intelligent in encountering stimuli eliciting novel adaptive behaviors Autonomous choice of stimuli

14 Novel sensory organs in pill bugs: artificial tubes attached to antennae Tohru Moriyama Young Researchers Empowerment Center, Shinshu University

15 1. The antennae flagellum

17 3. Stair descent experiment

22 4. Results for normal antennae

23 L 1.27L L ≤ 10.5 mm

24 L > 10.5 mm

25 Short Long 5. Unfamiliar situation Teflon tube clamped on Can pill bugs use sense experienced through the tube?

26 6. Results for antennae with tubes Normal

27 Sense at tip of antennae Choose Ignore Stimuli sensed Pill bug Autonomous choice of stimuli Sense from tubes 7. Autonomous choice of stimuli through antennae Capacity

28 Short Long Normal Descent Suspending descent Artistic falling 8. Novel adaptive behavior

30 Sensation at tips of tubes? In humans: Sensation at tips of invisible tools (Yamamoto & Kitazawa, Nature, 2001) Sense from tubes
