Information Processing Styles

1. Linear v. Holistic/Logical v. Intuitive The left brain processes information in a linear and logical manner. This means that information is analyzed by piece until a bigger picture is formed. The left brain necessarily have to form a logical order of every piece of information before drawing conclusions. On the other hand, the right hemisphere processes information from whole, to pieces. The significance of details will be difficult to appreciate without an overview of the bigger picture. Unlike the left hemisphere, the right hemisphere starts with the conclusion before drawing the premises (Left v. Right, 2009).

2. Sequential v. Random The left hemisphere processes information in sequence while the right hemisphere processes information in a random manner. This explains why people with a dominant left hemisphere works well by planning and making lists, and would do well in following directions. This is not the case with people with dominant right hemisphere who prefer or rather, are used to doing things in no specific order (Left v. Right, 2009). 3. Symbolic v. Concrete Symbols and minute details are processed by the left hemisphere.

In general, people with a dominant left-hemisphere tend to process language and mathematical problems easily. This hemisphere is capable of comprehending language through phonetic analysis, as well as isolating small details from spoken words. In contrast the comprehension through the right hemisphere must necessarily involve participation of the senses. Unlike the left hemisphere, language is processed by matching patterns instead of analysis of details (Miller, 2007). 4. Verbal v. Non-verbal Left-brained individuals have no trouble with verbal expression.

They do not need any visual cues to remember things. Right-brained individuals are better with expressing themselves non-verbally because they need illustrations or at least a mental picture of things as part of mental processing (Left v. Right, 2009). 5. Reality v. Fantasy The left hemisphere is more adept when there are rules available to be followed. If none is available, it will eventually create one. On the other hand, the right-hemisphere usually misses the rules. This makes right-brained individuals less flexible and adaptable to the environment (Left v.

Right, 2009). Part II 1. Distances and three-dimensional space The concept of depth perception explains how distances are judged and how three-dimensional space is perceived (Hacker, 2002). In order to be able to judge distances and perceive three-dimensional space, depth perception uses a combination of different cues including monocular and binocular cues. Some monocular cues include motion parallax, perspective, relative size, focus. Motion parallax is the relative movement of objects that results simultaneously with the movement of an observer.

Objects that are closer to the observer, for example more relatively faster than objects that are farther, upon movement of the observer (Ferris, 1972). Cues on perspective results when parallel lines converge toward infinity allowing the observer to recreate the perception of distance between two objects (Hacker, 2002; Bruce, et. al, 1996). Perhaps one of the most interesting cues is focus. In this cue, the lens of the eyes increase/decrease its size in order to bring objects into focus. This gives the observer an approximation of the distance of the object given knowledge from previous experience.

In other words, if the observer has knowledge of the size of an object, the brain will be able to gauge the distance of such object and the others in its periphery (Hacker, 2002; Bruce, et. al, 1996). Binocular cues include convergence and accommodation. Both of these cues are referred to as occulomotor cues for depth perception. In convergence, the object converges when two eyeballs focus on the same object, causing the extraocular muscles to stretch. When the angle of convergence is larger, it creates a perception of farness (Bruce, et.

al, 1996). In accommodation, kinesthetic sensations that result from the contraction and relaxation of intraocular muscles are sent to brain for interpretation as to its distance or depth (Bruce, et. al, 1996). 2. Sense and Perception Sensation and perception are different processes. While sensation involves a passive process, perception is active. Sensation refers to the process of gathering information from the environment using the senses, through sight, sound, smell, taste and touch which will then be sent to the brain for interpretation.

Perception comes into play in this last part. Perception is the process of interpreting and making sense of the information gathered through sensation. It involves not only interpretation but also the selection and organization of data for easier translation into meaningful ideas (Goldstein, 2002). References Bruce, V. , Green, P. R. & Georgeson, M.
