Enhancing grammar assignment perceptions by increasing assignment demands: Extending additive interspersal
research to students with emotional and behavioral disorders.
followed by activity interspersal
consisting of the child and his/her parent listening to the piano for a few seconds.
This technique has been called interspersal
training, and it involves embedding low-probability demands in a series of high-probability demands.
For example, natural environment training is not unique to VB it began with Hart and Risley's (1975) work on incidental teaching, sign language is certainly not unique to VB, nor are interspersal
or behavioral momentum techniques.
Twenty learn units were presented for each of the 5 categories resulting in a random interspersal
of 100 learn units for a complete stimulus set.
Constant time delay, paired picture/word procedure, picture cuing, and interspersal
of known words were some methods used at this stage.
Etzel & LeBlanc, 1979; Lancioni & Smeets, 1986; Terrace, 1963; Touchette & Howard, 1984) and task variation and interspersal
stimulus prompts, response prompts, interrupted chains as establishing operations, interspersal
of known items).
The effects of known-item interspersal
on acquisition and retention of spelling and sightreading words.
A comparison of the effects of interspersal
and concurrent training sequences on acquisition, retention, and generalization of picture names.
An empirical analysis of interspersal
research evidence, implications and applications of the discrete task completion hypothesis.
Skinner's (2002) meta-analysis of interspersal
research posits that a completed discrete task within an assignment also functions as a reinforcing event.
