Purpose<br />

The purpose of this paper is to review the<br />

research literature <strong>on</strong> simultaneous prompting,<br />

a fifth prompting strategy that results in<br />

near errorless learning. This review includes<br />

skills <strong>and</strong> individuals taught using simultaneous<br />

prompting <strong>and</strong> strengths <strong>and</strong> weaknesses<br />

of simultaneous prompting as identified in<br />

the literature.<br />

Simultaneous Prompting<br />

Simultaneous prompting is a resp<strong>on</strong>se<br />

prompting strategy that results in near errorless<br />

learning. During this procedure the instructi<strong>on</strong>al<br />

cue <strong>and</strong> c<strong>on</strong>trolling prompt are<br />

presented c<strong>on</strong>currently or simultaneously<br />

with probes c<strong>on</strong>ducted prior to the instructi<strong>on</strong>al<br />

sessi<strong>on</strong> to measure skill acquisiti<strong>on</strong><br />

(Gibs<strong>on</strong> & Schuster, 1992; Schuster, Griffen,<br />

& Wolery, 1992). Simultaneous prompting<br />

c<strong>on</strong>sists of three comp<strong>on</strong>ents (a) baseline or<br />

full probe sessi<strong>on</strong>s, (b) assessment or daily<br />

probe sessi<strong>on</strong>s, <strong>and</strong> (c) instructi<strong>on</strong>al sessi<strong>on</strong>s.<br />

During baseline/full probe sessi<strong>on</strong>s, data are<br />

collected <strong>on</strong> the students’ identificati<strong>on</strong> or<br />

completi<strong>on</strong> of all stimuli within the program.<br />

Baseline/full probe sessi<strong>on</strong>s are presented<br />

prior to the beginning of instructi<strong>on</strong> <strong>and</strong> typically<br />

following mastery of a set of stimuli prior<br />

to presentati<strong>on</strong> of the next set of stimuli. Full<br />

probe sessi<strong>on</strong>s may serve as baseline c<strong>on</strong>diti<strong>on</strong>s<br />

as well as maintenance c<strong>on</strong>diti<strong>on</strong>s. As-<br />

sessment/daily probe sessi<strong>on</strong>s which measure<br />

acquisiti<strong>on</strong> of the stimuli targeted for instructi<strong>on</strong>,<br />

are presented prior to each instructi<strong>on</strong>al<br />

sessi<strong>on</strong>. Assessment/daily probe sessi<strong>on</strong>s provide<br />

for independent resp<strong>on</strong>ding opportunities<br />

for the students. Instructi<strong>on</strong>al sessi<strong>on</strong>s are<br />

c<strong>on</strong>ducted following assessment/daily probe<br />

sessi<strong>on</strong>s each day. During instructi<strong>on</strong>al sessi<strong>on</strong>s<br />

the stimulus <strong>and</strong> the c<strong>on</strong>trolling prompt<br />

are presented c<strong>on</strong>currently.<br />

Method<br />

An electr<strong>on</strong>ic search of ERIC was c<strong>on</strong>ducted<br />

with simultaneous prompting used as the keyword.<br />

Articles also were identified through the<br />

reference lists of research articles <strong>and</strong> a published<br />

review of the literature <strong>on</strong> simultaneous<br />

prompting (Morse & Schuster, 2004). Articles<br />

were included if (a) they employed simultaneous<br />

prompting in an experimental design <strong>and</strong><br />

(b) were published in a peer review journal. A<br />

total of 35 peer reviewed articles <strong>and</strong> <strong>on</strong>e<br />

review of the literature were identified. Investigati<strong>on</strong>s<br />

that were not included in the initial<br />

review of the literature are included in Tables<br />

1 <strong>and</strong> 2.<br />

Demographic Variables<br />

Participants. A total of 35 published studies<br />

spanning eighteen years (1992–2010) <strong>and</strong><br />

<strong>on</strong>e review of the literature <strong>on</strong> simultaneous<br />

prompting are included. In an initial review of<br />

the literature Morse <strong>and</strong> Schuster (2004)<br />

identified 18 published studies which examined<br />

simultaneous prompting including 74<br />

participants. Since the initial review of the<br />

literature an additi<strong>on</strong>al 17 studies have been<br />

identified with an additi<strong>on</strong>al 62 participants<br />

for a total of 35 published studies <strong>and</strong> 136<br />

participants.<br />

Simultaneous prompting has been employed<br />

predominately with students in elementary<br />

school (Akmanoglu & Batu, 2004;<br />

Batu, 2008; Birkan, 2005; Griffen, Schuster, &<br />

Morse, 1998; Kurt & Tekin-Iftar, 2008; Parrott,<br />

Schuster, Collins, & Gassaway, 2000; Schuster<br />

& Griffen, 1993; Schuster, Griffen, & Wolery,<br />

1992; Singlet<strong>on</strong>, Schuster, & Ault, 1995; Tekin<br />

& Kircaali-Iftar, 2002; Tekin-Iftar, 2008; Tekin-<br />
