Spontaneous Alternation Behavior describes the tendency to alternate in their pursuit of different stimuli in consecutive trials despite a lack of training or reinforcement. The Behavior emerged from experiments using animals, mainly rodents, who naturally demonstrated the behavioral pattern when placed in previously unexplored maze shapes. Spontaneous Alternation testing .   Abstract. Factors affecting spontaneous alternation behavior (SAB) in animals, for example, age, gender and species studied; type of apparatus and cues employed; and neuro-anatomical, neuro-chemical and motivational status of the organism, were by: Spontaneous alternation behavior in Paramecium. Abstract. Spontaneous alternating behavior (SAB), the tendency of an organism to successively turn left and right in a maze, is a standard metric of short-term memory in developmental and pyschopharmacological by: Spontaneous alternation is the behavioral pattern emerging from an organism's tendency to explore places that have been least recently visited without any reinforcement by:

Spontaneous alternation is achieved when an animal enters a new arm rather than returning to one visited previously. Since rodents typically prefer to investigate new environments, over the course of multiple arm entries, they usually show a tendency to enter a less recently visited by: Y Maze Spontaneous Alternation is a behavioral test for measuring the willingness of rodents to explore new environments. Rodents typically prefer to investigate a new arm of the maze rather than returning to one that was previously visited. The spontaneous alternation task is used to assess spatial working memory in rodents and is based on the innate tendency of rodents to explore a prior unexplored arm of a T- or Y-maze. Thus, a rodent typically remembers which arm it has just visited. Two types of procedures are classically described. Spontaneous alternation is a reduced tendency to return to the same location on successive trials. It is measured in rats in a T maze and is thought to depend on an intact hippocampus. In human infants, we measured alternation in the tendency to reach toward one of two identical toys placed in locations to the left and right of by:

SAB, unlike other mnestic tasks, does not require any prior training or reinforcement. Because of its close correlation with the development and function of the hippocampus in mice, it is thought to reflect a type of by: 2. Spontaneous alternation is a reduced tendency to return to the same location on successive trials. It is measured in rats in a T maze and is thought to depend on an intact hippocampus. Spontaneous alternation is manifested even in the early trials of a discrimination-learning experiment, where only one of the choices is reinforced. Indeed, that was the setting in .
