Does the amount of sleep one gets affect memory recall?
ETHICS/IVCRADD
Confidentiality: No personal information will be disclosed. ID numbers allocated to people is a way to ensure confidentiality.
Right to withdraw: Participants should be allowed to withdraw of the experiment without any questions asked.
Voluntary Participation: Researchers need to be careful that there is no coercion when the participants consent. The participant should be able to withdraw at anytime without any negative consequences.
Accurate Reporting: Even if the results go against the hypothesis, researchers have to release the results to the public. There can't be any fabricated data. Credit must be given to everyone involved.
Informed Consent: Participants must be given the aim of the experiment and any information given must be clear and concise. The participant must also sign a consent form and if their are a minor they need their parents consent. Deception can be used in the experiment but it cannot be harmful.
Deception/Debrief: Debriefing is a necessary step at the end of the experiment. Deception can be used but only if the participants are told about it afterwards. If any harm is done to the participants during the experiments, the researchers have an obligation to ensure that are helped to repair.
Variables
Independent Variable: The variable that gets manipulated in a study
Dependent Variable: The variable that get measured
Controlled Variable: The variables that stay the same to ensure accuracy in the experiment
Extraneous Variable: The uncontrollable variables that effect the accuracy of the experiment
Memory
Long Term Memory
Declarative Memory: Memories of facts that can be consciously recalled.
Semantic memories: memory that stores info about the world. E.g. facts, definitions, rules, concepts, everyday knowledge.
Procedural Memory: Memories of how to perform different actions like riding a bike or breathing
Episodic Memory: Memories of personal experiences. Stores context and physical and psychological condition at the time
Memory Recall: The process of receiving information from the past. There are three types of recall
Free recall: Free recall is the process of when a person is given a list of things to remember and then have to recall them in any order. Free recall usually displays the recency effect.
Recency effect: The effect to remember more of the first and last items on a list compared to the middle of the list.
Serial recall: Serial Recall is being able to recall items or events in the order it happened. During serial recall in LTM, the sequence is repeated until it is one memory, rather then multiple items.
Cued recall: Cued recall is when a person is given a list of items and then tested with cues to remember certain items. Participants are given pairs to study and then the experimenter gives a cue to recall the word it was originally paired with.
Sleep
REM sleep: A type of sleep where there are random eye movement and the sleeper dreams vividly.
non-REM sleep
Stage 1: Light sleeping, 5-10 minutes
Stage 2: Eye movements stop, heart rate slows and body temperature decreases. Body prepares to enter deep sleep.
Stage 3: This stage is deep sleep. It is hard to be woken up at this point. There is no eye movement or muscle activity. If woken up the person feels disorientated for a few minutes.
Design types
Qualitive Data: Descriptions, words, meaning, pictures, verbal statements.
Quantitative data: Numbers, thoughts and feelings on a scale of 1 to 10,
Sample Size
Young Adults without any mental impairments.
