What does theory of mind mean? Why are autistic individuals thought to have poorly developed theory of mind? Identify some other key symptoms of autism.
Which of the following is an illustration of experience-dependent plasticity? A) Rats raised in cages with toys have more dendritic spines and more synapses per neuron than rats raised in cages without this stimulation B) The brain expects experiences that all humans have (such as visual and auditory input) and uses them to shape the structure of the brain. C) Adults who became blind early in life were better able to discriminate musical pitch than were those who became blind later in life. D) All of the above
What is true of prenatal effects on brain plasticity? Parents' experiences before conception can influence their children's later brain development. Positive experiences influence prenatal brain development, whereas negative experiences do not. Negative experiences influence prenatal brain development, whereas positive experiences do not. Gene expression cannot be altered by prenatal experiences but can be altered after a child is born.
Using Piaget’s theory of cognitive development, describe howyou would explain the death of a parent to children 4, 9, and13 years of age.
In the sheep brain, the cerebellum is Anterior or Posterior (select the best answer) to the cerebral hemispheres. This is different than in the human brain, where the cerebellum is ventral or dorsal (select the best answer) to the cerebral hemispheres. The right or left (select the best answer) hemisphere controls the movement of the right arm.
Epilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures. About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain. A common goal of the surgical procedure to treat epileptic seizures is to reduce the connection between the two hemispheres of the brain. By cutting through this structure, an epileptic seizure occurring on one side of the brain will not be spread to the other side. Identify the structure that connects the two hemispheres of the brain.
Should drugs be prescribed to children who have ADHD? What about adults? On what scientific evidence do you base your opinion?
The brain is particularly sensitive to being shaped by input from the environment during sensitive periods of neuroplasticity. Which of the following, related to this statement, is true? A) Experience-dependent and experience-expectant plasticity during sensitive periods allow children to adapt to the environment to which they are exposed. B) Properties of sensitive period plasticity are adaptive, but also leave the brain vulnerable to harm. C) Sensitive periods are only relevant during prenatal development, and the postnatal environment shapes the brain via different mechanisms D) A & B are both correct
EVOLUTION CONNECTION Scientists often use measures of“higher-order thinking” to assess intelligence in other animals.For example, birds are judged to have sophisticated thoughtprocesses because they can use tools and make use of abstractconcepts. Identify problems you see in defining intelligence inthese ways
Do you believe that one's intelligence as a baby will yield the same level of intelligence later in life? Use your knowledge about the factors that can influence infant brain development and your understanding of nature and nurture influences to support your answer.
If the mind is not included in the set of things considered to be physical, then this would mean that the mind is non-physical and therefore distinct from the physical brain. Is it possible that there are non physical components of reality and can the mind be different from the physical brain?
What is neuroplasticity? How do people become more intelligent? How does the diagram of the neurons “At birth verses at age 6, demonstrate how people become more intelligent? How are our brains like muscles? When do our brains grow the most?
