Top-Down ProcessingIII. SensationCurrent LectureI. Most complex functions require both hemispheres working together.a. Left-Hemisphere: More active with language, logic and math.i. This side treats things in a serial matter/ serial ladder (chronological).b. Right-Hemisphere: More active with spatial tasks, music and visual recognition.i. This side treats things as a whole.c. Conclusion: There are better ways to describe ability and personality than right and left hemisphere.II. Chapter 6: Sensation and Perceptiona. Two types of processing information:i. Bottom-Up Processing: Analysis that begins with sense and works its wayup to the brain’s integration of sensory information.ii. Top-Down Processing: Information-processing guided by the higher levels of mental processes.1. Example: Experience and expectationsIII. In sensory research processing is traditionally divided into two processes:a. Sensation: Detecting energy from environment and encoding it as neural signs. b. Perception: Selecting, organizing and interpreting sensations.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. Adding meaning to the sensations.IV. Sensationa. Psychophysics: Study of the relationships between the physical characteristics ofstimuli and our psychological or sensory experience of them.i. Absolute Threshold: The minimum stimulation needed to detect a stimulus 50% of the
