Figure 1. Percentage of 10-s intervals with inappropriate verbal behaviors during baseline (A), Social Story<br />

without perspective sentences (B), Social Story with perspective sentences (C), <strong>and</strong> withdrawal (A)<br />

for Taro.<br />

mary investigator asked <str<strong>on</strong>g>the</str<strong>on</strong>g>m to initiate <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

first sessi<strong>on</strong>.<br />

In <str<strong>on</strong>g>the</str<strong>on</strong>g> first of <str<strong>on</strong>g>the</str<strong>on</strong>g> four sessi<strong>on</strong>s in Interventi<strong>on</strong>,<br />

Taro’s teacher read <str<strong>on</strong>g>the</str<strong>on</strong>g> SS without PS for<br />

him. Taro, <str<strong>on</strong>g>the</str<strong>on</strong>g>n, took a turn to read <str<strong>on</strong>g>the</str<strong>on</strong>g> Social<br />

Story out loud. His teacher provided c<strong>on</strong>trolling<br />

prompt (i.e., modeling) when he read <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

story incorrectly. The teacher for Kenji read<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> SS without PS with giving examples <strong>and</strong><br />

explaining <str<strong>on</strong>g>the</str<strong>on</strong>g> meaning of <str<strong>on</strong>g>the</str<strong>on</strong>g> each sentence.<br />

Starting with <str<strong>on</strong>g>the</str<strong>on</strong>g> sec<strong>on</strong>d sessi<strong>on</strong>, both students<br />

read <str<strong>on</strong>g>the</str<strong>on</strong>g> SS without PS out independently.<br />

A formal reading time for SS without<br />

PS was provided <strong>on</strong>ce each day, just prior to<br />

initiating observati<strong>on</strong> of <str<strong>on</strong>g>the</str<strong>on</strong>g> target behavior.<br />

During <str<strong>on</strong>g>the</str<strong>on</strong>g> rest of <str<strong>on</strong>g>the</str<strong>on</strong>g> day, <str<strong>on</strong>g>the</str<strong>on</strong>g> Social Story<br />

book was placed <strong>on</strong> a shelf to be accessible to<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> student.<br />

Interventi<strong>on</strong> 2. This c<strong>on</strong>diti<strong>on</strong> was identical<br />

to Interventi<strong>on</strong> 1 with <str<strong>on</strong>g>the</str<strong>on</strong>g> excepti<strong>on</strong> that<br />

perspective sentences were added to a story<br />

used in Interventi<strong>on</strong> 1. The teachers provided<br />

students an SS with PS <strong>and</strong> asked <str<strong>on</strong>g>the</str<strong>on</strong>g>m to read<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> story. Because <str<strong>on</strong>g>the</str<strong>on</strong>g> c<strong>on</strong>tent of <str<strong>on</strong>g>the</str<strong>on</strong>g> SS with<br />

PS was identical to that of <str<strong>on</strong>g>the</str<strong>on</strong>g> SS without PS,<br />

with <str<strong>on</strong>g>the</str<strong>on</strong>g> excepti<strong>on</strong> of a perspective sentence,<br />

Taro read <str<strong>on</strong>g>the</str<strong>on</strong>g> story with a few prompts at <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

beginning of <str<strong>on</strong>g>the</str<strong>on</strong>g> interventi<strong>on</strong> phase, followed<br />

by no prompts from <str<strong>on</strong>g>the</str<strong>on</strong>g> sec<strong>on</strong>d sessi<strong>on</strong>. For<br />

Kenji, his teacher asked him to read <str<strong>on</strong>g>the</str<strong>on</strong>g> SS<br />

with PS, explaining <str<strong>on</strong>g>the</str<strong>on</strong>g> meaning of <str<strong>on</strong>g>the</str<strong>on</strong>g> added<br />

perspective sentence <str<strong>on</strong>g>the</str<strong>on</strong>g> first sessi<strong>on</strong> of <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

interventi<strong>on</strong> phase. He did not have any questi<strong>on</strong>s,<br />

<strong>and</strong> he read <str<strong>on</strong>g>the</str<strong>on</strong>g> story independently<br />

from <str<strong>on</strong>g>the</str<strong>on</strong>g> sec<strong>on</strong>d sessi<strong>on</strong>.<br />

Baseline 2. Taro’s did not provide him any<br />

opportunities to access <str<strong>on</strong>g>the</str<strong>on</strong>g> Social Story book<br />

(SS with PS) throughout <str<strong>on</strong>g>the</str<strong>on</strong>g> day. No Baseline<br />

2 was implemented for Kenji due to <str<strong>on</strong>g>the</str<strong>on</strong>g> terminati<strong>on</strong><br />

of <str<strong>on</strong>g>the</str<strong>on</strong>g> semester.<br />

Figure 1 shows <str<strong>on</strong>g>the</str<strong>on</strong>g> change of Taro’s persistent<br />

<strong>and</strong> aggressive verbal behaviors across Baseline,<br />

Interventi<strong>on</strong> 1, Interventi<strong>on</strong> 2, <strong>and</strong> Baseline<br />

2. As illustrated, during <str<strong>on</strong>g>the</str<strong>on</strong>g> first baseline<br />

phase, <str<strong>on</strong>g>the</str<strong>on</strong>g> percentage of his inappropriate<br />

verbal behaviors was high, for an average of<br />

49.1%, ranging from 19.4% to 86.1%. Following<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> implementati<strong>on</strong> of SS without PS, his<br />

inappropriate behaviors showed a downward<br />

trend, for an average of 10.6%, ranging from<br />

0.0% to 16.7%. It should be noted, however,<br />

that <str<strong>on</strong>g>the</str<strong>on</strong>g> difference in level between Baseline<br />

<strong>and</strong> Interventi<strong>on</strong> 1 was not substantial. After
