Psychological research supports which of the following claims?

A) Subliminal messages can influence what products people buy.
B) Newborn infants can recognize the sound of their own mother's voice.
C) Most of us use only 10% of our brain.
D) A psychologist can accurately diagnose someone's psychological disorder from responses to the Rorschach Inkblots.

There is a substantial body of research that shows newborn infants can recognize the sound of their own mother's voice. This recognition may begin before birth, and it can play an essential role in building a bond between mother and child.

Answer: A
While there was a lot of popular interest in the idea that subliminal messages could influence consumer behavior, studies on the topic have consistently shown that these messages are unlikely to have a significant impact. People may be aware of subliminal messages on some level, which negates any potential effect.

Answer: None
There is no scientific evidence to support the claim that humans only use 10% of their brain. While it's true that we may not use every part of our brain equally all the time, we do use the majority of our brain. This myth likely originated from early studies of brain function, which were limited in scope and technology.

Answer: D
Research has shown that the Rorschach Inkblot test is not a valid measure of personality or mental health. There is no evidence that psychologists can accurately diagnose someone's psychological disorder based on responses to this test.
