Modular Self-Reconfigurable Robot for Autonomous Rehabilitation Assistance in Daily Living Tasks for Spinal Cord Injury Patients

This paper presents a modular robot for assisting individuals with spinal cord injury with everyday tasks. The basic premise of modularity for task-variable environments is laid out, and the modular robot design is detailed including needs assessment, kinematics, and hardware. Early pilot testing of the robot is also described.

Interpretation and Matching Bias in a Reasoning Task

Subjects were required to construct verifying and falsifying cases of conditional rules in which the presence and absence of negative components was varied. Their responses gave some indication of consistent interpretation of the rules, generally conforming to Wason's (1966) idea of a “defective” truth table. Much of their behaviour, however, seemed to be determined by a task variable in the form of a tendency to construct instances which matched, rather than altered, the values named in the rules.
