Question

psychology questions for discovering psychology: sensation and perception 1. what did the brain do to change its perception of the host from large to small? 2. how does the video define perception? 3. give one example of a persons absolute threshold. what does this say about the sensitivity of our sensory receptors? 4. what is the
eal task of perception,\ according to the video? 5. what must the brain do in order to convert its sensations into perceptions? 6. what two things does the brain seem to look for in order to facilitate this process? 7. what happens when we remove one of these cues? 8. what does a quarterback have to calculate (almost instantly) to throw a ball to a receiver? 9. what happens when we change their visual field by 20 degrees? what happens when we remove the distortion? why does this happen? 10. what is the difference between bottom - up and top - down processing? 11. give some examples of the videos claim that what we perceive is an active construction of reality 12. how do edges and boundaries help us with our perceptions?

Explanation:

1. Without the video content, specific answers cannot be provided. However, in general, the brain may use context - clues, size - comparison with other objects, and past experience to change its perception of an object's size.
2. Perception is often defined as the process by which the brain organizes and interprets sensory information to give it meaning.
3. An example of an absolute threshold could be the softest sound a person can hear. This shows the sensitivity of our auditory receptors; a low absolute threshold indicates high sensitivity.
4. The real task of perception might be to make sense of the sensory input in a way that is useful for survival and interaction with the environment.
5. The brain must organize, interpret, and integrate sensory information to convert sensations into perceptions.
6. The brain may look for patterns and consistencies in the sensory input to facilitate this process.
7. Removing a cue can lead to misperception or a less accurate perception as the brain has less information to base its interpretation on.
8. A quarterback has to calculate the receiver's position, speed, and the ball's trajectory almost instantly.
9. Changing the visual field by 20 degrees can cause disorientation and misperception. Removing the distortion may lead to a readjustment period as the brain has to re - calibrate. This happens because the brain has adapted to the distorted visual input.
10. Bottom - up processing starts with the sensory input and builds up to a perception, while top - down processing uses prior knowledge and expectations to interpret sensory input.
11. Examples could include optical illusions or the way we perceive faces in clouds, where our brain actively constructs a meaningful perception from the available sensory data.
12. Edges and boundaries help us to distinguish objects from their background and from each other, which is crucial for object recognition and perception.

Answer:

1. Without video, cannot answer precisely. Brain may use context, comparison, experience.
2. Process of organizing and interpreting sensory info for meaning.
3. Softest sound heard; shows auditory receptor sensitivity (low threshold = high sensitivity).
4. Make sense of sensory input for survival and interaction.
5. Organize, interpret, integrate sensory info.
6. Patterns and consistencies in sensory input.
7. Can lead to misperception due to less info.
8. Receiver's position, speed, ball's trajectory.
9. Disorientation with change; readjustment when distortion removed due to adaptation.
10. Bottom - up: starts with sensory input; Top - down: uses prior knowledge.
11. Optical illusions, face - perception in clouds.
12. Distinguish objects from background and each other for recognition.
