Which of the following statements best reflects what the effect of ‘Natural Fear Level’ in the table tells us?
about an animal. Three groups of children were shown a picture of an animal that they had
never seen before (a quoll). Then one group was told a negative story (in which the quoll is
described as a vicious, disease?ridden, bundle of nastiness that eats children’s brains), one
group a positive story (in which the quoll is described as a harmless, docile creature that
likes nothing more than to be stroked), and a final group weren’t told a story at all. After the
story children rated how scared they would be if they met a quoll, on a scale ranging from 1
(not at all scared) to 5 (very scared indeed). To control for the natural anxiousness of each
child, a questionnaire measure of trait anxiety was given to the children and used in the
analysis. The (edited) R output is below. The next two questions relate to this output.
a. The child’s natural level of fear had a significant relationship with their fear
beliefs about the animals.
b. The child’s natural level of fear did not have a significant relationship with
their fear beliefs about the animals.
c. The type of information given to the children had a significant relationship
with the child’s natural level of fear.
d. The type of information given to the children did not have a significant
relationship with the child’s natural level of fear.
e. Natural fear levels were significantly different in the groups of children.
