A key concern regarding television advertising aimed at children is that it:

Concept: Socialisation is the process through which a child takes on the values, attitudes and behaviour patterns of the surrounding culture, and mass media is one of its agents. Advertising is persuasive communication whose purpose is to sell goods, so the value it repeatedly models is that owning and consuming products brings happiness and status. Up to roughly eight years of age a child cannot reliably recognise persuasive intent, so an advertisement is received as information rather than judged as a sales appeal.

Application: The stem asks for a concern, that is, a documented harmful outcome. Because the content of children’s television advertising is product-centred and its audience cannot yet discount it, consumer-socialisation studies report a rise in materialism: stronger wanting of advertised goods, repeated purchase requests to parents (often called pester power), and greater dissatisfaction with what the child already owns. This is why the syllabus lists the encouragement of materialistic values and desires as the key concern.

Cross-check with the other claims:

• Improves nutritional awareness reliably — food advertising aimed at children is dominated by confectionery, sugary drinks and other high-fat, high-salt, high-sugar items, so exposure is linked to a preference for those foods, not to a dependable gain in nutrition knowledge.

• Develops independent thinking skills — a persuasive message received before the age of recognising persuasive intent invites acceptance of the claim, which is the opposite of evaluating it independently.

• Promotes physical activity consistently — viewing is sedentary and displaces active play, so more advertising exposure means more screen time, not more movement.

Result: The key concern about television advertising aimed at children is that it encourages materialistic values and desires.
