小孩不吃菜？ 给奖品可能有用
<p>一项英国研究称，如果学龄前小孩不愿吃蔬菜，只要他们尝尝味道，就给他们一些小奖励，或许可以帮助小孩吃下原本不想吃的食物。研究发现，每当3、4岁的小孩吃点不喜欢的蔬菜，家长就发贴纸给他们，可以慢慢改变小孩的态度。几周后，获得这种奖励的小孩，对蔬菜的评价变高，从1到2级（大概介于“恶心”与“还好”），上升到2到3级，相当于“还好”与“好吃”之间。研究显示，在实验室的味觉试验中，有贴纸奖励的小孩也更愿意吃更多蔬菜，不管是红萝卜、芹菜、小黄瓜、红辣椒、卷心菜还是碗豆。而口头赞美之所以无效，是因为小孩可能觉得爸妈说的话“不真诚”。</p><p><span word="If">If</span> <span word="your">your</span> <span word="preschoolers">preschoolers</span> <span word="turn">turn</span> <span word="up">up</span> <span word="their">their</span> <span word="noses">noses</span> <span word="at">at</span> <span word="carrots">carrots</span> <span word="or">or</span> <span word="celery">celery</span>, <span word="a">a</span> <span word="small">small</span> <span word="reward">reward</span> <span word="like">like</span> <span word="a">a</span> <span word="sticker">sticker</span> <span word="for">for</span> <span word="taking">taking</span> <span word="even">even</span> <span word="a">a</span> <span word="taste">taste</span> <span word="may">may</span> <span word="help">help</span> <span word="get">get</span> <span word="them">them</span> <span word="to">to</span> <span word="eat">eat</span> <span word="previously">previously</span> <span word="shunned">shunned</span> <span word="foods">foods</span>, <span word="a">a</span> <span word="UK">UK</span> <span word="study">study</span> <span word="said">said</span>.</p><p><span word="Though">Though</span> <span word="it">it</span> <span word="might">might</span> <span word="seem">seem</span> <span word="obvious">obvious</span> <span word="that">that</span> <span word="a">a</span> <span word="reward">reward</span> <span word="could">could</span> <span word="tempt">tempt</span> <span word="young">young</span> <span word="children">children</span> <span word="to">to</span> <span word="eat">eat</span> <span word="their">their</span> <span word="vegetables">vegetables</span>, <span word="the">the</span> <span word="idea">idea</span> <span word="is">is</span> <span word="actually">actually</span> <span word="controversial">controversial</span>, <span word="researchers">researchers</span> <span word="wrote">wrote</span> <span word="in">in</span> <span word="the">the</span> <span word="American">American</span> <span word="Journal">Journal</span> <span word="of">of</span> <span word="Clinical">Clinical</span> <span word="Nutrition">Nutrition</span>.</p><p><span word="That">That</span>'<span word="s">s</span> <span word="because">because</span> <span word="some">some</span> <span word="studies">studies</span> <span word="have">have</span> <span word="shown">shown</span> <span word="that">that</span> <span word="rewards">rewards</span> <span word="can">can</span> <span word="backfire">backfire</span> <span word="and">and</span> <span word="cause">cause</span> <span word="children">children</span> <span word="to">to</span> <span word="lose">lose</span> <span word="interest">interest</span> <span word="in">in</span> <span word="foods">foods</span> <span word="they">they</span> <span word="already">already</span> <span word="liked">liked</span>, <span word="said">said</span> <span word="Jane">Jane</span> <span word="Wardle">Wardle</span>, <span word="a">a</span> <span word="researcher">researcher</span> <span word="at">at</span> <span word="University">University</span> <span word="College">College</span> <span word="London">London</span> <span word="who">who</span> <span word="worked">worked</span> <span word="on">on</span> <span word="the">the</span> <span word="study">study</span>.</p><p><span word="Verbal">Verbal</span> <span word="praise">praise</span>, <span word="such">such</span> <span word="as">as</span> "<span word="Brilliant">Brilliant</span>! <span word="You">You</span>'<span word="re">re</span> <span word="a">a</span> <span word="great">great</span> <span word="vegetable">vegetable</span> <span word="taster">taster</span>," <span word="did">did</span> <span word="not">not</span> <span word="work">work</span> <span word="as">as</span> <span word="well">well</span>.</p>
