Here is evidence for
- Encouraging playful parent-child activities with speech sounds
- Equipping teachers to foster explicit auditory learning from an early age
- Including Playful Sounds in the speech & language clinician's tool kit
Auditory Learning and Speech & Language Development:
"Studies of normal perception and [speech] production skills have shown many instances of perception preceding production." (Groenen, Maassen, Crul & Thoonen, 1996.)
Phonological processes of perception and speech production likely enhance each other. (Adams & Gathercole, 1995; Groenen et al., 1996; Mayo, Scobbie, Hewlett & Waters, 2003; Rvachew, 1994; Rvachew, 2006; Rvachew, Nowak & Cloutier, 2004; Wolfe & Mesaris, 2003.)
Various language skills, such as verbal working memory, word retrieval, and speech comprehension under noise, depend upon phonological processing abilities. (Nittrouer, 2002; Rvachew and Jamieson (1989) cited in Groenen et al., 1996; Rvachew, et al., 2004.)
Short-term phonological memory is correlated with articulation and language skills in young children. (Adams & Gathercole, 1995; Gathercole & Baddeley (1990) cited in Groenen et al.,1996.)
Early development of phoneme awareness is associated with improved speech and later morphological awareness. (Kirk & Gillon, 2007; Rvachew et al., 2004.)
Children with speech and language deficits can make significant and lasting improvement in phonemic awareness skill and reading, in contrast with students whose therapy ameliorates speech or language problems but does not address PA. (Gillon, 2000; Gillon, 2005; Justice, 2006; Kirk & Gillon, 2007; Rvachew et al., 2004; van Kleeck et al., 1998.)
Phonemic Awareness Principles
Phonemic awareness differentiates between children who succeed in reading and those who struggle. (Catts & Kamhi, 1999; Vellutino et al., (1996) cited in Gillon, 2000; Grossen, 1997; Schuele & Boudreau, 2008; Smith, Simmons & Kameenui (n.d.); Swank & Catts, 1994; van Kleeck, Gillam & McFadden, 1998.)
Because speech sounds do not exist as separate units in natural speech, (Nittrouer, 2002) and because of the consequences of failure to learn to discern and manipulate these sounds in words, instruction in phonemic awareness is critical. (Grossen, 1997; Nittrouer, 2002; Schuele & Boudreau, 2008; Smith et al. (n.d.); van Kleeck et al.,1998.)
Instruction in phonemic awareness is effective and efficient. (Grossen 1997; Schuele & Boudreau, 2008; Smith et al. (n.d.); Swank & Catts, 1994.)
Specific tasks develop phonemic awareness (PA). (Grossen, 1997; Schuele & Boudreau, 2008; van Kleeck et al., 1998)
The focus should be on early instruction and prevention. (Gillon, 2005; Grossen, 1997; van Kleeck et al., 1998).
Children succeed in learning PA skills via instructional structure or 'scaffolding.' Task elements are manipulated from simpler to more complex, and to provide for initial supports, then gradual independence:
- concrete representations to help focus attention
- opportunities for student to produce specific sounds
- control of phonological awareness difficulty (e.g. rhyming tasks are simplest, segmentation and manipulation tasks are most difficult)
- control of response difficulty (e.g. receptive/pointing tasks before expressive/naming tasks)
- control of task units (e.g. segmenting by word before segmenting by syllable)
- control of linguistic characteristics (e.g. 'stretchy' continuant sounds before 'non-stretchy' stop sounds)
- reduced scaffolding support as children become more proficient (e.g. 'easier' and 'more difficult' task versions)
Phonemic awareness proceeds in overlapping stages. Mastery at one step is not required to benefit from the next. (Schuele & Boudreau, 2008.)
Three- and 4-year-olds, including those with moderate or severe speech impairment, can learn phonemic awareness via developmentally appropriate activities. (Gillon, 2005; Schuele, & Boudreau, 2008.) (Phonemic awareness is part of a larger category called 'phonological awareness,' which includes pre-skills such as rhyming. In Playful Sounds, the term ‘phonemic awareness’ is used to include both).
Motor Learning in Therapy for Speech Sound Disorders:
"Phonetic placement has been shown to be effective for teaching a child how to say a new sound." (Powell, Elbert, Miccio, Strike-Roussos & Brasseur (1998), cited by Rvachew, 2006.)
For speech, research supports approaches that address the phonological system as a whole, improving perceptual, articulatory and phonological knowledge of misarticulated sounds. (Rvachew, 2006.) However, the efficacy of nonspeech oral-motor exercises is not supported. (Lof & Watson, 2008; Powell, 2008; Ruscello, 2008; Steeve & Moore, 2009.)
