Contextual Conditioning of Drug Tolerance and Drug Addiction Research on the contextual conditioning of drug tolerance shows it is an important factor in understanding drug addiction in humans. Context is a way of noting that the likelihood of a behavior or response depends on certain conditions. Contextual conditioning is said to occur when a person becomes conditioned not only to the drug but also to the environmental circumstances or cues in which the drug is taken. Studies have shown that tolerance

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

The behaviours of eating and sexual activity in humans are regarded in terms of motivated behaviour such that they appear to be purposeful and directed toward a goal. The hypothalamus is a brain structure located deep within the brain that‚ although small in size less than 1% of the brains total mass‚ is largely responsible for and controls a wide variety of human behaviour including motivation‚ eating‚ sexual activity and emotion. However in trying to understand this role it is important to first
