When comparing the force of static friction and the force of kinetic friction between a horizontal surface and an object, choose which statement below is true. If more than one statement is true, choose the most complete choice.

What is the Force of friction acting on the block?

[MidA] Given the baseline data depicted below, which subsequent data path offers the most likely prediction of future problem behavior in the absence of a behavior intervention?  

[MidA] Considering the baseline data illustrated below, which continuing data path best predicts future problem behavior in the absence of intervention?

[MidA] Which best exemplifies a functional response definition?

A Supersonic Waterfall : There were periods of time in the past when a massive saltwater waterfall occurred at the Strait of Gibraltar. The water falling in this waterfall reached supersonic speeds; that is, by the time it hit the bottom, the water reached speeds larger than the speed of sound.Ignoring air resistance, what was the height necessary for the water to reach the speed of sound? Assume the speed of sound is 3.4 x 102 m/s.

[MidA] In consideration of the baseline data illustrated below, which continuing data path best predicts future problem behavior in the absence of intervention?

[MidA] Fredrick’s mother reports that he often cries and hides when told it is time for bed most nights. The behavior analyst observes Fredrick just before bedtime for several days and graphs the data. Next, she instructs Fredrick’s parents to implement a visual-schedule intervention, which provides their son with a clear sequence of activities before bedtime. Fredrick’s parents report that they are happy with the outcome of the intervention. Which basic operation of the science of behavior analysis is missing from this example?

[MidA] Naomi receives a referral to support a student who frequently calls out in class without raising their hand. Naomi observes the student during a 45-minute language-arts block and documents 22 instances of calling out. At the next visit, she recommends that the teacher implement a reinforcement system for hand-raising and remind the student of the class rules before each lesson. One week later, Naomi returns and observes only 6 instances of hand raising in 45 minutes. She graphs the data and compares the frequency from before and after the strategy was introduced, showing a noticeable reduction. Which basic operation of the science of behavior analysis is missing from this example?

[MidA] Tania delivers a parenting class and teaches the task-analyzed skill of using reinforcement. Tania asks a volunteer named Isaiah to come to the front while she demonstrates the skill. She then asks Isaiah to demonstrate the skill while she provides prompts and to practice with feedback in front of the class. After the demonstration, Tania performs a pretest of each participant’s percent of accurate steps of the skill without additional prompts or practice. Next, she provides training using the prompts and practice with feedback, followed by another test for each participant post-training. Isaiah scores higher than most other participants on his pre-test and post-test. This is most likely an example of what type of threat to internal validity?
