Final answer:
Expert systems are not capable of critical decision making as they lack fluid intelligence, consciousness, and intentionality. Artificial Neural Networks do not react to emotional stimulation since current AI technology does not encompass emotional understanding and is considered weak AI, performing specific tasks.
Step-by-step explanation:
Characteristics of Expert Systems
Characteristics of expert systems include their ability to use heuristics to solve complex problems, reliance on rules of thumb to guide them, and their use of cognitive skills to make decisions. However, expert systems are not capable of critical decision making in the same way humans are. The critical decision making involves understanding complex relationships and solving problems, a trait of fluid intelligence, which expert systems lack because they do not possess true consciousness or intentionality.
Artificial Neural Networks
An artificial neural network (ANN) is designed to look for patterns in large data sets, use feedback during training, and process multiple attempts for finding the correct answer. ANNs are modeled after the human brain's network of neurons and are part of the artificial intelligence spectrum. However, they do not react to emotional stimulation, as this is beyond the capabilities of current artificial intelligence, which primarily operates within the realms of weak AI, performing specific tasks without genuine emotional understanding.
