The experimenter sat at a table across from the child and introduced two tools(fig.1).one tool,the “blicket”,was demonstrated ringing a bell. The blicket was not described ; the experimenter simply called attention to it then performed the action by inserting the tool into the slot of a box a single time and quickly striking an internal bell 2 to 3 times . the child was invited to try once too.
The other tool,the “dax”,was equally affordant for ringing the bell but was not demonstrated achieving that goal. Instead,children performed the action of unwrapping it from colorful paper. An inner transparent wrapping layer was included to give preliminary visual access to the tool during unwrapping . the experimenter was animated about the dax, making it particularly salient pointing out its characteristics(e.g,color,texture)
