Which of the following is NOT the best example of a conditioned reinforcer for Jax’s behavior (see the cutie’s picture below)?  

**YOU ARE REQUIRED TO SHOW WORK FOR THIS QUESTION TO RECEIVE CREDIT!** Bob is picking what sport he wants to play this school year. The probability that he plays soccer is 0.18, the probability that he plays baseball is 0.34, and the probability that he plays both soccer and baseball is 0.15. (Round to three decimal places as needed.)   a. What is the probability that Bob plays soccer or baseball? [a] b. What is the probability that Bob does not play baseball but plays soccer? [b] c. Based off your answer for part b, would it be unusual for Bob to play baseball but not soccer? [c] (yes/no), because the probability is [d] (less than/more than) 0.05. d. If we know that Bob plays baseball, what is the probability that Bob also plays soccer? [e]

Match each term with the best description. You will not use all descriptions.

Please fill in the blank, using your own words in the space provided.  Rasmussen et al. (2024) described two methods for evaluating conditioned reinforcement.  In one of those methods, a neutral stimulus is paired with an unconditioned reinforcer. Then, researchers compare responding for a previously mastered responde during extinction with and without the delivery of the neutral stimulus. This is called the method.

Please fill-in-the-blank by selecting one of the dropdown box options provided. In one of the conditioned reinforcer tests, a neutral stimulus is paired with an unconditioned reinforcer. Then, the rate of a mastered response is compared when it results in nothing versus the delivery of the neutral stimulus.  For example, if a red light (the SD) was associated with high-fives, then we would test whether the client responded during extinction sessions with or without a red light. In this assessment, if a high-five functions as a conditioned reinforcer, then during the test trials you would expect the organism to when it resulted in nothing versus the tests that resulted in only the red light. 

A nurse is teaching a health and nutrition class about foodborne illnesses. Which statement by the client is correct about Toxoplasma gondii?

A nurse knows that most foodborne illnesses cause which symptoms?
