The changing role of gesture in linguistic development: a developmental trajectory and a cross-cultural comparison between British and Finnish children.

We studied how gesture use changes with culture, age and increased spoken language competence. A picture-naming task was presented to British (N = 80) and Finnish (N = 41) typically developing children aged 2-5 years. British children were found to gesture more than Finnish children and, in both cultures, gesture production decreased after the age of two. Two-year-olds used more deictic than iconic gestures than older children, and gestured more before the onset of speech, rather than simultaneously or after speech. The British 3- and 5-year-olds gestured significantly more when naming praxic (manipulable) items than non-praxic items. Our results support the view that gesture serves a communicative and intrapersonal function, and the relative function may change with age. Speech and language therapists and psychologists observe the development of children's gestures and make predictions on the basis of their frequency and type. To prevent drawing erroneous conclusions about children's linguistic development, it is important to understand developmental and cultural variations in gesture use.

Breast cancer awareness and barriers to symptomatic presentation among women from different ethnic groups in East London.

BACKGROUND: During 2001 to 2005, 1-year breast cancer survival was low in ethnically diverse East London. We hypothesised that this was due to low breast cancer awareness and barriers to symptomatic presentation, leading to late stage at diagnosis in women from ethnic minorities. We examined ethnic differences in breast cancer awareness and barriers to symptomatic presentation in East London. METHODS: We carried out a population-based survey of 1515 women aged 30+ using the Cancer Research UK Breast Cancer Awareness Measure. We analysed the data using logistic regression adjusting for age group and level of deprivation. RESULTS: South Asian and black women had lower breast cancer awareness than white women. South Asian women, but not black women, reported more emotional barriers to seeking medical help than white women. White women were more likely than non-white women to report worry about wasting the doctor's time as a barrier to symptomatic presentation. CONCLUSION: Interventions to promote early presentation of breast cancer for South Asian and black women should promote knowledge of symptoms and skills to detect changes, and tackle emotional barriers to symptomatic presentation and for white women tackle the idea that going to the doctor to discuss a breast symptom will waste the doctor's time.
