Cognitive Psychology Chapter 7 Summary

Lots of research forms an put together biopsychosocial approach which realizes the biological, psychological, and sociocultural factors

Memory is divided into three categories. These categories consist of: sensory memory, short term memory and long term memory, out of these short term memory is the main focus in this essay. It has been widely researched due to interest of how much memory can be stored, how long this memory can be stored for and what information is memorised.

“Information flows from the outside world through our sight, hearing smelling, tasting and touch sensors. Memory is simply ways we store and recall things we 've sensed.” When we recall memories, the original neuron path that we used to sense the experience that we are recalling is refined, and the connection is made stronger. Sensory information in stored for only a few seconds in the cortex of the brain. This information can then progress to short-term memory, and then long-term memory, depending on the importance of the information received.

In Chapter 7 of our What Is Psychology textbook, we learned about the importance, details and strategies of memory techniques. One type of memory is Short Term, which only last up to thirty seconds before forgetting. Whenever has to remember a number or a name, they often repeat the information multiple times so that the Short Term Memory can transition into Long Term Memory. In order for this transition to occur, the information must be constantly repeated, or important enough to be held in the permanent memory, which helps create a “folder” with all retaining information and reminiscing. Another way short term can become long term is using a method called Chunking, this breaks the bigger pictures into smaller ones for the brain to remember,

If the logical mind, isn’t enough to create motivation within us! Should we then let emotions decide what we should be doing? Should we use emotions to prioritize? This might look really emotional, but let’s just look at it by this;

Some people like sweet things and others don’t , or some people may like sports and others won’t. Our brain tells us what we like and don’t like by controlling our emotions, it does this with the Cerebrum or by using our genes.

A hypothesis is an explanation that can be tested based on observation. A statistical hypothesis is testable explanation based on observation and different variables. A null hypothesis explains what the results of the experiment will be if the original hypothesis is wrong. An alternate hypothesis is the opposite result if there is or isn’t a null hypothesis. Semmelweis hypothesized that bacteria/virus filled extremities resulted in higher death rates.

2) Isolation/causation. Isolation is if only thing changing is that which is being manipulated whether up or down, then the change in effect is caused by the change in IV (the thing manipulated). It is harder to get isolation from psychology, than that from physical experiments. In experiments, even in a double blind study, the IV and subjects are changing. This can prove to make things even more difficult when the DV is based on the subject, the change on the DV may be due to difference in samples and not on changes due to the IV. Where a confounding variable is the environment or situation, the difference in subjects such as age or gender is a subject variable. This is important to note the differences as subject difference Subject variables

Cognitive psychology is the scientific investigation of human cognition, that is, all our mental abilities – perceiving, learning, remembering, thinking, reasoning, and understanding. The term “cognition” stems from the Latin word “

In general, there are three types of memory: sensory memory, short-term memory and long-term memory. Sensory memory, by definition, is the preservation of information in its original sensory form, for a fraction of a second. This means that when you smell, touch and/or see anything, the impression of the occurrence will last for a couple of moments. This

Smith (2001) defines psychology as the study of the mind. One major subset within the broad study of psychology is popularly known as cognitive psychology. According to Aukrust (2011), cognitive psychology is a branch of psychology that deals with the study of mental processes which includes how people or individuals think, perceive, learn and remember. As a part of the larger cognitive science field, this psychology branch is by means related to other disciplines such as neuroscience, linguistics and philosophy. Processes included in cognition are judging, thinking, remembering, knowing and problem solving.

Memory is the process involved in retaining, retrieving and using information about stimuli, images, events, ideas and skills after the original information is no longer present. We can relate this case with what we learn in psychology. Short term memory holds information from 15 until 30 seconds whereas long term memory holds information for years. Short-term memory (STM) is the system that is involved in storing small amount of information for a brief period of time while long-term memory (LTM) is the system that is responsible for storing information for long periods of time and recall information about past events in lives and knowledge learned.
