2 Project Description Primary Objective: Design an apparatus that will be used to present three-dimensional objects in a match-to-sample procedure Purpose: To assess the beluga whale s visual and auditory perception abilities Scope of Project: 1 Testing Apparatus 2 sets of 42 Target Objects Testing Procedure Supporting Documentation Budget: $3500

3 Primary Design Criteria Operator and whale safe Quiet operation Durable & weatherproof Corrosion-proof No external power Compact and mobile 1-person operation Able to block whale and trainer s view of both object sets 24 total design width 1-3sec target time between object set display, 5 sec max 5lb max object weight

4 Final Concept

5 Final Design

6 Apparatus Operation 1. Apparatus is assembled 2. Objects are attached 3. Apparatus is rotated over the pool 4. Apparatus is lowered into underwater testing ti position 5. Sample object is lowered 6. Sample object is raised 7. Choice set is lowered 8. Choice set is raised 9. Apparatus is raised into attachment position 10. Apparatus is rotated over the beach 11. Objects are removed

9 System Testing Results: Pool Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Average Filling Tub Emptying Tub Setup Changing sets Raising/lowering Objects Disassemble Note: All times are in seconds.

10 System Testing Results: On-site Tested in Mystic Aquarium on 5/15/09 Apparatus functioned as designed Trainers examined apparatus and objects for whale safety Trainers approved of the design and its functionality Recommendations from trainers: Add labels for sample and choice pulleys Ensure double blind test by creating a shield to block view of experimenter from the whale Tether apparatus to beach Replace top shield Replace coated wires Adjust to swing apparatus to left instead of right Add ability to roll up shields out of the way Ensure all objects are whale safe, i.e. no sharp edges
