When an employer signs a check, it is endorsing the transfer of money from the business' account to the employee. The act of signing the check is considered an endorsement, and is considered proof of the intent of the payer to transfer funds to the payee.
This model was proposed by Howard Gardner in his 1983 book Frames of Mind: The Theory of Multiple Intelligences. Gardner articulated eight criteria for a behavior to be considered an intelligence.
Visual/spatial intelligence: includes the ability to think in terms of physical space, detect patterns, and manipulate physical space ; Bodily/kinesthetic intelligence: includes the ability to use the body to send messages, communicate needs, and solve problems ; Naturalistic intelligence: includes the ability to observe patterns in nature and a love of outdoors ; Interpersonal intelligence: includes the ability detect the moods, feelings, and motivations of others
