Ms. march is teaching matthew to do his laundry. she has written a task analysis for doing laundry, which consists of 36 steps. she conducted an initial assessment to identify which steps matthew could already do, and she discovered that the only step he can presently do independently is to open the lid to the washer. she decides to use total task presentation as her method of teaching this complex chain of behaviors, using a least-to-most prompting strategy. what might be one disadvantage to this procedure?
a)this procedure is likely to make each training session quite long. b) matthew may become confused with the sequence of the task because the teaching procedure involves having him do the last step, then the last two steps, and so on. c) because matthew's present behavior will be placed on extinction until he emits a new behavior that is closer to the terminal behavior, he will likely become very frustrated. d) all of these are reasonable concerns given the teaching context.

Blue computers, a major pc manufacturer in the united states, currently has plants in kentucky and pennsylvania. the kentucky plant has a capacity of 1 million units a year and the pennsylvania plant has a capacity of 1.5 million units a year. the firm divides the united states into five markets: northeast, southeast, midwest, south, and west. each pc sells for $1,000. the firm anticipates a 50 perc~nt growth in demand (in each region) this year (after which demand will stabilize) and wants to build a plant with a capacity of 1.5 million units per year to accommodate the growth. potential sites being considered are in north carolina and california. currently the firm pays federal, state, and local taxes on the income from each plant. federal taxes are 20 percent of income, and all state and local taxes are 7 percent of income in each state. north carolina has offered to reduce taxes for the next 10 years from 7 percent to 2 percent. blue computers would like to take the tax break into consideration when planning its network. consider income over the next 10 years in your analysis. assume that all costs remain unchanged over the 10 years. use a discount factor of 0.1 for your analysis. annual fixed costs, production and shipping costs per unit, and current regional demand (before the 50 percent growth) are shown in table 5-13. (a) if blue computers sets an objective of minimizing total fixed and variable costs, where should they build the new plant? how should the network be structured? (b) if blue computers sets an objective of maximizing after-tax profits, where should they build the new plant? how should the network be structured? variable production and shipping cost ($/unit) annual fixed cost northeast southeast midwest south west (million$) kentucky 185 180 175 175 200 150 pennsylvania 170 190 180 200 220 200 n. carolina 180 180 185 185 215 150 california 220 220 195 195 175 150 demand ('000 units/month) 700 400 400 300 600
