Answer: CONCRETE JUDGEMENT.
Judgment can be defined as an act of concluding on an opinion or decision. For example, taking a bite of a salty meal and making a face, this can be termed to be judgment.
Concrete judgment can be said to be decision made due to them being appealing to the senses or as a result of a physiological response.
