Being in a relationship means being happy together, celebrating the differences Featured photo credit: avesisland.info . I'd had serious relationships before meeting my fiancé, with a couple lasting for years. I thought I was an adult; I thought I knew how to be a. It also involves the cognitive processes required to process of time thinking about the actual process that occurs when you perceive the legs or the change in position of the body in relation to objects in the environment.
Broadbent and others in the 's adopted a model of the brain as a limited capacity information processing system, through which external input is transmitted. The Information Processing System Information processing models consist of a series of stages, or boxes, which represent stages of processing.
Arrows indicate the flow of information from one stage to the next. Critical Evaluation A number of models of attention within the Information Processing framework have been proposed including: However, there are a number of evaluative points to bear in mind when studying these models, and the information processing approach in general. The information processing models assume serial processing of stimulus inputs.
Serial processing effectively means one process has to be completed before the next starts. Parallel processing assumes some or all processes involved in a cognitive task s occur at the same time.

There is evidence from dual-task experiments that parallel processing is possible. It is difficult to determine whether a particular task is processed in a serial or parallel fashion as it probably depends a on the processes required to solve a task, and b the amount of practice on a task. Parallel processing is probably more frequent when someone is highly skilled; for example a skilled typist thinks several letters ahead, a novice focuses on just 1 letter at a time.
The analogy between human cognition and computer functioning adopted by the information processing approach is limited. Computers can be regarded as information processing systems insofar as they: BUT - i the human brain has the capacity for extensive parallel processing and computers often rely on serial processing; ii humans are influenced in their cognitions by a number of conflicting emotional and motivational factors.
Most laboratory studies are artificial and could be said to lack ecological validity.
How The Computer Works: The CPU and Memory
In everyday life, cognitive processes are often linked to a goal e. Although these laboratory experiments are easy to interpret, the data may not be applicable to the real world outside the laboratory.
More recent ecologically valid approaches to cognition have been proposed e. Attention has been studied largely in isolation from other cognitive processes, although clearly it operates as an interdependent system with the related cognitive processes of perception and memory.
The more successful we become at examining part of the cognitive system in isolation, the less our data are likely to tell us about cognition in everyday life. These influences are known as 'top-down' or 'conceptually-driven' processes.
The information processing approach in psychology is closely allied to the computational theory of mind in philosophy; it is also related, though not identical, to cognitivism in psychology and functionalism in philosophy Horst, Two types[ edit ] Information processing may be vertical or horizontal, either of which may be centralized or decentralized distributed. The horizontal distributed processing approach of the mids became popular under the name connectionism.
But "unlike in semantic networks, it is not a single node that has a specific meaning, but rather the knowledge is represented in a combination of differently activated nodes" Goldstein, as cited in Sternberg, Models and theories[ edit ] There are several proposed models or theories that describe the way in which we process information.
Every individual has different information overload point with same information load, because individuals have different information-processing capacity Eppler and Mengis, Sternberg's triarchic theory of intelligence[ edit ] Sternberg's theory of intelligence is made up of three different components: Creativeness is the ability to have new original ideas, and being analytical can help a person decide whether the idea is a good one or not.
In the middle of Sternberg's theory is cognition and with that is information processing. These processes move from higher-order executive functions to lower order functions. This theory in action can be explained by working on an art project. First is a decision about what to draw, then a plan and a sketch. During this process there is simultaneous monitoring of the process, and whether it is producing the desired accomplishment. All these steps fall under the metacomponent processing, and the performance component is the art.
The knowledge-acquisition portion is the learning or improving drawing skills. An example of this is the working memory model.
The central executive is like the secretary of the brain. It decides what needs attention and how to respond. The central executive then leads to three different subsections. The first is phonological storage, subvocal rehearsal, and the phonological loop. These sections work together to understand words, put the information into memory, and then hold the memory.Caught on Film Processing Emotions -- A Taste of Real, Raw Communication w/ Conor + Brittany
The result is verbal information storage. The next subsection is the visuospatial sketchpad which works to store visual images.
The storage capacity is brief but leads to understanding of visual stimuli. Finally, there is an episodic buffer. This section is capable of taking information and putting it into long-term memory. In order for these to work, the sensory register takes in via the five senses: These are all present since birth and are able to handle simultaneous processing e.
In general, learning benefits occur when there is a developed process of pattern recognition. The sensory register has a large capacity and its behavioral response is very short 1—3 seconds.
