Of adoptees whose biological mothers had schizophrenia and who were raised in disturbed family environments, 36.8% were likely to develop schizophrenia; of adoptees whose mothers did not have schizophrenia and who were raised in disturbed family environments, 5.3% were likely to develop schizophrenia. What is the most appropriate conclusion of these results? a. Genetic factors are most important to determining whether a person is likely to develop schizophrenia. b. Environmental factors are most important to determining whether a person is likely to develop schizophrenia. c. Environmental factors and genetic factors interact to determine whether a person is likely to develop schizophrenia. d. Not enough information is provided in order to make a conclusion about environmental versus genetic contributions to schizophrenia.

Environmental factors and genetic factors interact to determine whether a person is likely to develop schizophrenia.

The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language. The topic of this reading is: a. Language b. Brain c. Frontal Lobe d. Emotion

Frontal Lobe

Which of the following conclusions can be drawn from the case study of Phineas Gage's accident, which led to brain injury? a. Frontal lobe injury causes people to be incapable of controlling their emotional impulses. b. Injury to the frontal lobe does not affect behavior. c. Injury to the brain causes changes in behavior, and specific brain areas are linked to particular behaviors. d. Injury to the brain causes changes in behavior, but specific brain areas are not linked to specific behaviors.

Injury to the brain causes changes in behavior, and specific brain areas are linked to particular behaviors.

The brain's parietal lobe is located immediately behind the frontal lobe, and is involved in processing information from the body's senses. It contains the somatosensory cortex, which is essential for processing sensory information from across the body. The topic of this reading is: a. Somatosensory cortex b. Parietal Lobe c. Frontal Lobe d. Your body senses

Parietal Lobe

The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language. The Main Idea of this reading is: a. The frontal lobe sits as the back of the brain and is linked to the central sulcus. b. The frontal lobe is found at the front of the brain, and it is concerned with our reasoning, motor control, emotion, and language. c. There is a fissure called the sulcus that extends backwards. d. The brain has a lobe and it is located at the front of the skull.

The frontal love is found at the front of the brain, and it is concerned with our reasoning, motor control, emotion, and language.

The brain's parietal lobe is located immediately behind the frontal lobe, and is involved in processing information from the body's senses. It contains the somatosensory cortex, which is essential for processing sensory information from across the body. The Main Idea of this reading is: a. There is a cortex called the somatosensory cortex. b. The parietal lobe is important because it is located behind the occipital lobe and has a cortex. c. The parietal lobe is located directly behind the frontal lobe and is involved in managing information from our senses. d. Your body senses information from the somatosensory cortex and acts on it.

The parietal love is located directly behind the frontal lobe and is involved in managing information from our senses.

Rosemary had a stroke about a year ago and now she cannot understand what people are saying to her. This is embarrassing for her, so she responds using vague language and tries to make it appear as though she understands. Which area of Rosemary's brain was likely damaged by the stroke? a. Wernicke's area b. Broca's area c. prefrontal cortex d. occipital cortex

Wernicke's area

Which of the following senses is associated with the temporal lobe? a. vision b. audition c. pain d. touch

audition

________ is a neurotransmitter with roles in pleasure and pain modulation. a. norepinephrine b. GABA c. acetylcholine d. beta-endorphin

beta-endorphin
