Sensation & Perception
Sensation VS. Perception? Or will they be a team?
Understanding the Seperation of Each
Sensation is the process of detecting physical energy from your environment and turn it into signals to give the brain. Perception gives the signals meaning an is usually influenced by memory, motivation, emotion, and even culture at times. This process of converting these physical signals in the environment into neural activity in the brain is known as transduction. This relationship is mainly studied by psychophysics (the study of our sensitivity to stimuli of different strengths).
Absolute threshold is the minimum stimulation needed to cause perception. while the signal detection theory claims that there is no absolute threshold and that the threshold changes with factors such as fatigue, attention, expectation, motivation, and emotional distress. Difference threshold on the other hand gets to have its own law! Kind of unfair, no? The difference threshold is the minimum difference between any two stimuli that can be detected 50% of the time.
