Comparison of Pavlovian serial conditional discrimination in rats and hamsters in the same experimental situation

Brazilian Journal of Medical and Biological Research, 2001
The present study compares behavioral changes between two distinct rodent groups, hamsters (Mesocricetus auratus) and Wistar rats, when submitted in the same homogeneous experimental situations to a serial conditional discrimination procedure which ...

A THEORY OF ATTENDING AND REINFORCEMENT IN CONDITIONAL DISCRIMINATIONS [PDF]

Journal of the Experimental Analysis of Behavior, 2005
A model of conditional discrimination performance (Davison & Nevin, 1999) is combined with the notion that unmeasured attending to the sample and comparison stimuli, in the steady state and during disruption, depends on reinforcement in the same way as predicted for overt free-operant responding by behavioral momentum theory (Nevin & Grace, 2000).

Patterned ELR‐Gelatin Hydrogels Enable Rapid Endothelial Monolayer Formation via Bioactive Matrix Chemistry and Surface Topography

Advanced Healthcare Materials, EarlyView.
Micro‐ and nano‐patterned elastin‐like recombinamer (ELR) hydrogels integrate bioactive matrix chemistry with defined surface topography. The combined cues promote rapid endothelial cell capture, alignment, and monolayer formation on soft substrates.

“TRANSITIVE INFERENCE” IN MULTIPLE CONDITIONAL DISCRIMINATIONS [PDF]

Journal of the Experimental Analysis of Behavior, 1993
We used multiple conditional discriminations to study the inferential abilities of pigeons. Using a five‐term stimulus series, pigeons were trained to respond differentially to four overlapping pairs of concurrently presented stimuli: A+B−, B+C−, C+D−, and D+E−, where plus and minus indicate the stimulus associated with reinforcement and extinction ...

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

Advanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Rat's time estimation under conditional discrimination procedure / Estimação de tempo em ratos submetidos a um procedimento de discriminação condicional

Psicologia: Reflexão e Crítica, 2007
In a feature positive conditional discrimination procedure, a stimulus A is not followed by reinforcement when presented alone, but it is always followed by reinforcement when it is preceded by stimulus X.

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

Advanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...
