The students behavior change is best described as ontogenic and an instance of extinction Ontogenic behavior refers to behavior that is acquired or modified during an individuals lifetime through learning experiences and interaction with their environment The students decision to stop staying late based on the teachers consistent lack of acknowledgement over three weeks is a direct result of their personal learning history not an inherited trait Phylogenic behavior refers to behaviors that are inherited as a result of the evolutionary history of a species they are genetically determined eg reflexes fixed action patterns The students study habits are not a phylogenic trait Extinction occurs when a previously reinforced behavior is no longer followed by the reinforcing consequence resulting in a decrease in the frequency of the behavior in the future In this scenario the students behavior of staying late was presumably maintained by the hope of teacher approval reinforcement When this reinforcement was withheld teacher doesnt acknowledge the student the behavior decreased student stops staying late which is the definition of extinction Respondent behavior or classical conditioning involves the elicitation of reflexes by antecedent stimuli eg salivating to a bell after pairing it with food The students voluntary action of staying late is an operant behavior maintained by its consequences not a reflex Cultural behavior refers to practices or customs learned and transmitted within a social group often verbally While social context plays a role the primary mechanism described is individual learning history and contingency management
