    >Dear all,
    >
    >This is a somewhat long message. It is more relevant for those interested
    >in the pragmatics of questions - specifically, in the context of
    >experimental research. If anyone can give me a feedback in terms of the
    >"pragmatic effects" in the explanation of the results I've got on the last
    >question of this version of the adoption paradigm:
    >
    >Story:
    >
    >One day a turtle gave birth to a little baby. Right after the baby was born
    >the Turtle died without ever seeing the baby. The baby was found and taken
    >right away to live with toads in a place where there are lots of toads. The
    >baby grew up with toads and never saw another turtle again.
    >
    >Questions 1 to 4: ...
    >
    >Question 5:
    >
    >Now that the baby is all grown up, what kind of animal is it? A turtle or a
    >toad?
    >
    >Follow-up Story:
    >
    >When the baby was growing up it became sick. A doctor came and, with a
    >needle, took out all of the old blood that the baby got from its mother
    >when it was born. The doctor then went to the animal that was taking care
    >of the baby and took some of its blood to give to the baby. So the baby got
    >all new blood like the blood of the toad.
    >
    >Question 6:
    >
    >Now that the baby is all grown up, what kind of animal is it? A turtle or
    >a toad?
    >
    >4, 5, 6 and 7 year olds and adults from Brazil participated in the
    >experiment. In question 5, most of the partipants in all age groups
    >significantly chose the birth parent kind - the turtle.
    >In question 6, most adults chose the birth parent kind, but most children
    >in all ages chose the adoptive parent kind - the toad.
    >
    >I wonder if this asymmetry in the results of question 6 is due to the fact
    >that questions 5 and 6 are exactly the same. Here are three possible ways
    >that could explain the asymmetry:(If anyone can give me a feedback if my
    >remarks about possible pragmatics factors in the explanations are out of
    >the mark in terms of the pragmatic of questions or can suggest a more
    >precise explanation.)
    >
    >The first one would argue that children don't have any understanding of a
    >relation between blood transfusion and species kind identity and that their
    >answers were simply an artifact of the task. It can be that the reiteration
    >of the question in the context of the blood story made children infer the
    >following implicature: the right answer to this question should be
    >different from my previous answer. This is because the additional
    >information given by the blood story would make the second question
    >irrelevant if the speaker was searching for the same answer he had obtained
    >before. In other words, if children don't have any belief about the
    >relation between blood transfusion and species kind identity, the
    >pragmatics of the task would bias them to a specific answer. Therefore most
    >children chose the adoptive parent kind in the second answer simply because
    >most of them chose the birth parent kind in the first question.
    >
    >The second one would argue that children have a type of belief commitment
    >to the idea that blood transfusion changes kind identity and that their
    >answers were simply a consequence of this belief - in this case there is no
    >bias in the experiment and the second question would achieve relevance as a
    >test of this belief. To understand the plausibility of this second
    >explanation, it is important to point out that in Brazil as in many other
    >places adults talk about blood as if it were the substance that determines
    >family kind identity - people are of the same family because they share the
    >same blood. I don't know exactly the level of belief commitment involved in
    >this way of talk - if this is simply a metaphor without any belief
    >commitment, if this is a loose way of talk driven by a belief with half
    >understood content or if this is literal way of talk driven by a belief
    >with a somewhat well understood content(probably different Brazilians are
    >in each of these possibilities). But it can be that Brazilian children
    >interpret this way of talk more literally and understand blood as the
    >essence that determines family kind identity. And it can also be that when
    >reasoning about the task, most children generalize from family kind
    >identity to species kind identity - what is plausible since the story
    >evokes the mother-baby relationship. In this case, they would choose the
    >adoptive parent kind.
    >
    >The third one would be a compromise between the first two explanations. It
    >is neither that children don't have any understanding of a relation between
    >blood transfusion and species kind identity nor that they have a stable
    >understanding of such a relation. It is neither that children's answers are
    >simply driven by the pragmatics of the task nor that there is no bias in
    >the experiment. It is rather that children have a half understood idea of
    >the relation between blood transfusion and kind identity and that the bias
    >of the task led them to a more literal interpretation and a consequent
    >choice of the adoptive parent kind answer.
    >
    >All of them can explain the asymmetry - adults' answers would be driven
    >simply by their belief that blood transfusion does not change species kind
    >identity. And of course it can be that different children answered in
    >different ways according to any of these explanations.
