Question

Quizplus · Accepted Answer

The environmental cumulative deficit hypothesis suggests that the negative effects of underprivileged rearing conditions on IQ increase over time, meaning that the longer a child remains in those conditions, the more detrimental the effects will be. Choice A is incorrect because the hypothesis suggests the opposite - that the effects on IQ worsen over time, rather than improving. Choice B is also incorrect because the hypothesis suggests that most poor children are not resilient and will experience negative effects on IQ. Choice C is not supported by the hypothesized relationship between economic disadvantage and IQ, and it is not necessary to administer IQ tests more frequently to economically disadvantaged children.
