Associations Between Parent Mental State Language and Child Inhibitory Control in Children Who Are Deaf or Hard of Hearing

Longitudinal Influence of Family Environment on Language Outcomes of Deaf and Hard of Hearing Children

PURPOSE

Many child-, hearing-, and device-related factors contribute to spoken language outcomes in children who are deaf and hard of hearing (DHH). Recently, the family environment has been implicated as another contributing factor in language development. However, most studies on the role of families in language outcomes of children who are DHH are cross-sectional in nature and fail to draw directional conclusions. This study investigated the bidirectional relationship between attributes of the family environment and the spoken language outcomes of DHH children by examining data collected over approximately 1 year.

METHOD

Caregiver-child dyads composed of 57 typically hearing (TH) children and 53 DHH children and their primary caregiver completed a standardized, self-report family environment assessment, along with three standardized measures of receptive language at two separate home visits, separated by approximately 1 year.

RESULTS

Family environments of DHH and TH children did not differ significantly. In the DHH and TH groups, families that reported placing a greater emphasis on intellectual and cultural pursuits at the initial visit (T1) had children with better language outcomes at the second visit (T2), above and beyond the contribution of T1 language. Additionally, in the DHH group only, families that reported a greater emphasis on achievement and competition at T1 had children with poorer language skills at T2.

CONCLUSIONS

Families that emphasize intellectual-cultural environments had DHH and TH children with better language skills 1 year later, whereas those that deemphasized competition and perfection had DHH children with better language skills 1 year later. These findings highlight the importance of family environment and dynamics in contributing to language development in all children, but particularly DHH children, who are at a heightened risk for language delays.

Real-time spoken word recognition in deaf and hard of hearing preschoolers: Effects of phonological competition

This study investigates how phonological competition affects real-time spoken word recognition in deaf and hard of hearing (DHH) preschoolers compared to peers with hearing in the normal range (NH). Three-to-six-year olds (27 with NH, 18 DHH, including uni- and bilateral hearing losses) were instructed to look at pictures that corresponded to words alongside a phonological competitor (e.g., /bin-pin/) vs. an unrelated distractor (e.g., /toy-bed/). Phonological competitors contrasted in either voicing or place of articulation (PoA), in the onset or coda of the word. Relative to peers with NH, DHH preschoolers showed reduced looks to target in reaction to the spoken words specifically when competition was present. DHH preschoolers may thus, as a group, experience increased phonological competition during word recognition. There was no evidence that phonological properties (voicing vs. PoA, or onset vs. coda) differentially impacted word recognition.
