Dr. Ramirez is a sleep researcher who records the rhythmic electrical patterns of the brain. A) EEC B) MRI scans C) PET scans D) 45. He is most likely to use which of the following methods? monitoring blood levels Which of the following is NOT characteristic of the scientific approach? A) Casual or uncontrolled observations B) C) D) 46. Clear and defined concepts Valid and reliable instruments Curious, skeptical, humble attitudes 47. Which of the following is NOT one of the purposes for sensory adaptation? A) Focusing on novel stimuli B) Reducing background chatter C) Increasing stimulation to an unmotivated state D) Providing personally-useful perceptionsExplanation / Answer
Electroencephalography (EEG), is an instrument attached to one's brain to read brain signals when an individual is in deep slumber. The waves keep changing in REM and NREM. A sleep researcher measures and records the rhythmic electrical patterns of the brain through an EEG.
Thus, the correct answer is A.
An approach is scientific when it's objective, empirical, standardized and has substantiate proofs. Subjectivity does not play a role in a scientific study. Valid and reliable instruments, clear and defined concepts, curious, skeptical and humble attitude is of utmost importance in a scientific study.
Thus, the correct answer is A.
Sensory adaption focuses on helping an individual adapt to one's surroundings. It first focuses on a novel stimuli, and if it's constant, the brain cells no more signals to concentrate on it. The stimulation is then reached to an unmotivated state. For instance, you enter a room and someone is wearing a very strong cologne. The waft just hits your nostrils. You are at first very frustrated and annoyed by it, however, with time you adapt.
Thus, the correct answer is D.
