Gina is a BCBA who wants to determine whether providing access to bubbles would function as a reinforcer for her client.

Devon would like to prepare Jaxson for an upcoming trip to the dentist, where the dentist only needs to briefly look over Jaxson’s teeth and gums.

He decides it would be safest to run many trials first with toy dental object touching his inside his mouth, then a toothbrush then other basic dental tools prior to the dentist appointment. Which teaching method would be best for the behavior analyst to use and why?

Calculate the amount of heat required to convert 10.0 grams of ice at –20.°C to steam at 120.°C. (Sp. heat of H2O(s) = 2.09 J/g•°C,  Sp. heat of H2O(l) = 4.18 J/g•°C, Sp. heat of H2O(gas) = 2.03 J/g•°C; heat of fusion of H2O(solid) = 333 J/g, heat of vaporization of H2O(liquid) = 2260 J/g).

Bruno is a 3-year-old whose parents bring him to the ABA center for continued treatment after his initial evaluation. Bruno does not ask for things and spends a lot of time on his own while engaging in repetitive behaviors. When the behavior analyst attempts to engage with Bruno, he does not respond. He is not observed to engage with many items, and his parents report that he does not have many items for which he is motivated while at home. Given this scenario, which of the following would be most appropriate for the behavior analyst to do FIRST?

Chana is working with Zvi in math class. Zvi is having difficulty with single digit addition word problems. Chana and Zvi work together to build a deck of flashcards with word problems written on one side and the correct word answer on the other.  They begin by going through the cards slowly and identifying Zvi’s problem areas.  They then set a timer for 1 minute and go through the cards quickly to see how many Zvi can answer correctly in the 1-minute timing. They continue these quick 1-minute timings across several sessions until Zvi is fluent in single digit addition word problems. Chana is using which basic element while teaching in this scenario?

Given this scenario, which of the following factors is impacting the effectiveness of the rule?

Three identical flasks contain three different gases at standard temperature and pressure. Flask A contains CH4, flask B contains CO2, flask C contains N2. Which flask contains the largest number of molecules?

Rich is a BCBA working in a group home. One of his clients engages in self-injurious behavior and he wants to make sure the staff are implementing the behavior plan with fidelity. Rich has just directly observed staff working with the client and collected data on integrity of implementation for procedures in the plan. What is the very next step Rich should take when assessing treatment integrity?
