Perseverant responding in children's picture naming

Two groups of children were given pictures of animals to name as quickly as they could. The groups comprised 40 nursery aged children (mean age 3 ; 11) and 40 Year 2 children (mean age 6 ; 9) attending primary school in London. The 30 animals were presented one by one, on cards, and any errors made by the children were noted. Consistent with a similar object naming study with adults (Vitkovitch, Kirby & Tyrrell, 1996) and a study with children (Gershkoff-Stowe, 2002), picture naming errors referred to earlier named objects. However, while adults showed below-chance interference from objects that had only just been named (Lag 1), children were most susceptible to interference from very recently named objects (see also Gershkoff-Stowe, 2002). Furthermore, the proportion of younger children making Lag 1 errors was higher than the proportion of older children making Lag 1 errors. The results are discussed in relation to the activation levels of lexical representations.
