they are all able to sign and communicate in this manner. Bystanders may make negative comments about the deaf community in that family's presence, not realizing the child can hear.[citation needed] Deaf parents may not adequately understand that while a deaf person can look away or close their eyes, a hearing person cannot choose to ignore hurtful words so easily. The codas might often keep the hurtful comments to themselves adding additional weight to the already difficult circumstances. Discordant hearing status can also pose practical problems. Deaf and hearing people differ in visual attention patterns, with deaf people being more easily distracted by movement in peripheral vision. Deaf parents often instinctively use such movement to attract their child's attention, which can lead to difficulties engaging in joint attention with hearing toddlers. Parental sensitivity to child cues modulates this effect, with highly sensitive parents being more able to adjust to a child's differences from them. Support organizations Millie Brother established the organization CODA (Children of Deaf Adults) in 1983 as a non-profit organization for the hearing children of deaf parents. Its first annual conference took place in 1986 in Fremont, California. The conferences have grown and have taken on an international status, with attendees hailing from around the world. CODA aims to raise awareness about the unique experiences and issues of growing up between these two cultures. It provides a forum for CODAs to discuss the shared problems and experiences with other CODAs. Regardless of the spoken and sign languages used, CODA believes that such feelings and experiences that derive from the binary relationship of the two divergent cultures are universally felt by codas. CODA provides educational opportunities, promotes self-help, organizes advocacy efforts, and serves as a resource for codas raised in both signing and non-signing environments. There are support groups for deaf parents who may be concerned about raising their hearing children, as well as support groups for adult codas. One organization, KODAheart provides educational and recreational resources for deaf parents and hearing children through an educational website and pop-up camps. Several camps have been established for KODAs: Camp Mark Seven, which was established as the first KODA camp in 1998. They have two two-week programs for campers from 9 to 16 years old. Camp Grizzly, which hosts a one-week program for preteen and teen codas KODAWest, which is a week-long camp in Southern California held annually in the summer
