Which scientist studied the role of the environment in fostering cognitive growth?

You are a BCBA consulting with a teacher in a general education setting. She has one student who continues to talk to his peers sitting next to him during lecture. The teacher asks him to stop, but he continues. The teacher eventually asks him to sit in the hall because he is being disruptive. The next couple of days in class, the student continues to talk to his peers and the teacher continues to send him out in the hall. The teacher tells you that it is so much easier to teach when the student is out in the hall. The teacher’s continued behavior in throwing the student out of class is due to…

You are an RBT working with middle school aged children. The child you are working with has reportedly been completing only up to 25% of his assigned homework before class the next day. The parents have talked with the BCBA and voiced their concerns over their child’s completion of homework assignments. After taking proper preliminary data, your BCBA supervisor has created a program implementing reinforcement procedures that include providing the child you serve with a piece of candy for every question he completes correctly within a reasonable time period (1 to 2 minutes). After you have completed these procedures with great gains of 100% correct completion of assignments over 5 consecutive days, what is the most reasonable next step?

You are working as an RBT in a client’s home. Your BCBA supervisor gives you a new plan to implement with your client that includes a continuous reinforcement schedule for completing questions on homework tasks. You follow the program and even have a fellow RBT take fidelity data on your implementation. After implementing this intervention for one month, the mother comes to you and says that she is concerned because her child will not complete the entire homework task because she satiates on the reinforcer after completing half of the questions. You let the BCBA know what is happening. The BCBA goes to the home and tells the mother that you implemented the intervention poorly and another RBT should implement the intervention. Which core principle does this situation most likely violate?

You are working with a child who is learning to mand for information. After assessing the learner for preference, you identify his favorite games to use during the sessions. Then, you hide relevant, needed items to evoke a mand for the missing item. Manipulating the establishing operation for the missing item is likely to __________.

What is the best way to interpret the results of the function in the following FA data?

A therapist is working to increase the complexity of a client’s manding repertoire by targeting mands for action. The therapist uses environmental arrangement by locking the cabinet where the client’s favorite toys are located. The locked cabinet creates the opportunity for the learner to engage in the mand “unlock the cabinet”. In this scenario what is the source of control of the mand?

You are a BCBA working with a non-verbal child in middle school. You observe the child and talk to family. You come up with the overall conclusion that the child only requests what he wants by grunting. Those around the child do not know what he wants or needs, so you make that your first priority in skill acquisition. Which core principle does this best represent?

You are a BCBA at a local clinic that offers in home therapy. Your colleague typically takes the cases in the home while you work in the clinic. She came to your office one day and let you know that she is attracted to the client’s father. She says that he reciprocated the feelings and asked her on a date. She declined because she wants to avoid violating the ethical codes, but it is getting harder for her to work there because she really would like to date him. What advice can you give your colleague that follows all ethical guidelines?

You are aiding a professor who is a BCBA doing research in a local clinic. The study includes taking data on engagement behaviors of three participants during circle time. These behaviors include sitting with crossed legs on the floor, correctly responding to each question asked by the instructor, and imitating each motor movement modeled by the instructor. Your professor says this should be a very simple research study and there is very little risk of harm to the participant. Before you start taking data, the BCBA tells you to give the parents a sheet that explains the research procedures and have them sign off on the procedures. After the parents sign off, you begin taking baseline data alongside the BCBA. After taking baseline data, the BCBA has you read through the ethical guidelines. You realize that one element was missing at the beginning of the study. Which element was missed?
