Answer 3

no but i really need help

Answer 4

well thats why im here.

Answer 5

well Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns and random patterns that distract from the information.

Answer 6

thank you

Answer 7

so thasts not it

Answer 8

the actual answer is B

Answer 9

AP Psych? Did this exact example before

Weber's law - as the variation of the magnitude of two stimuli increase, they are more noticeable.
Absolute Threshold - (By Fechner) the level of stimulus to be detected at least 50% of the time
Sensory Adaptation - Our sense receptors (except for eyes) are able to adapt to changes to the point we don’t notice them. It is commonly confused with Habituation where we don’t notice things as the stimuli decreases.
Signal Detection Theory - The environment can influence our stimuli detection
The four categories are:
-Hit = P(Detection | Signal)
-Miss = P(No detection | signal) - A Type I error
-False Alarm - P(Detection | No Signal) - Type 2 Error
-Correct Rejection = P(No detection | No signal)
