A system has been constructed for the study of two- and three-choice behavior in animals, using either a free operant or discrete-trial procedure. An IBM-026 card punch is utilized to automatically program stimulus and reinforcement events, and to record choices and choice latencies. Eight Ss may be run simultaneously in the apparatus.

We simulate two types of environments to investigate how closely rats approximate optimal foraging. Rats initiated a trial where they chose between two spouts for sucrose, which was delivered at distinct probabilities. The discrete trial procedure used allowed us to observe the relationship between choice proportions, response latencies and obtained rewards. Our results show that rats approximate the optimal strategy across a range of environments that differ in the average probability of reward as well as the dynamics of the depletion-renewal cycle. We found that the constituent components of a single choice differentially reflect environmental contingencies. Post-choice behaviour, measured as the duration of time rats spent licking at the spouts on unrewarded trials, was the most sensitive index of environmental variables, adjusting most rapidly to changes in the environment. These findings have implications for the role of confidence in choice outcomes for guiding future choices.

The article iis devoted to the research of the institution of investigative judge introduced into the criminal procedure of the Kyrgyz Republic in 2019. The authors analyze the conceptual foundations of this institution, its procedural significance, as well as the legal model under Kyrgyz legislation in its comparative perspective with the legislation of Germany and some former Soviet republics. Two main achievements: the organizational and functional isolation of an investigating judge during the criminal procedure and granting them the power of deposition are seen by the authors as advantages of the Kyrgyz model of the institution of an investigative judge. The former is aimed at guaranteeing the objectivity, impartiality and neutrality of the judge considering the case on the merits, who is discharged judicial control in pre-trial procedure nowadays. The latter is aimed at implementing for the prosecution and defense the right to be equal parties of procedural opportunities to participate in evidence as an integral element of the adversarial principle.
