The Sociability Chamber operates on the principle of social choice behavior, where test subjects demonstrate their social preferences through voluntary movement between chambers containing different social stimuli. The apparatus consists of three interconnected chambers with removable dividers that contain sliding doors. During testing, stimulus animals are placed in round wire enclosures within the side chambers, allowing sensory interaction while preventing direct physical contact that could lead to aggressive behaviors.
Behavioral assessment relies on measuring time spent in each chamber, number of transitions between chambers, and specific behaviors such as sniffing, grooming, and approach behaviors directed toward the stimulus enclosures. Researchers typically score these behaviors through manual observation or video recording, with optional integration of video tracking software such as ConductVision for automated behavioral analysis. Social preference is quantified by comparing time spent in chambers containing social stimuli versus empty chambers, while social novelty recognition is assessed by comparing interactions with familiar versus unfamiliar stimulus animals.
The modular design permits various experimental configurations including biased conditioning protocols using aversive floor stimuli (stainless-steel grids) and unbiased preference testing with standard flooring. Removable doors allow researchers to establish conditioned place preference paradigms or restrict access during habituation phases.
