Outline and evaluate the working memory model (12 marks) Baddeley and Hitch proposed that memory has 4 components. The central executive, phonological loop, visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components, the phonological store (inner ear), which holds acoustically coded information, and the articulatory process (inner voice), which allows for sub vocal rehearsal (words you are about to say).
The other purpose of the stroop effect is that it shows the dominations of some parts of the brain and how functional areas are dominated. The studies that have been used to measure the functions in the brain using the FMRI and the EEG have shown that there is a selective activation of the cingulated cortex during the stroop task. stroop effect is tested using the colour identification task. This includes participants being asked to say as
Acetylcholine acts as a neuromodulator which engage in direct synaptic transmission between specific neurons. In the CNS acetylcholine plays a role in attention and arousal in the PNS it works as a major part of the autonomic nervous system and works to activate muscles (Waymire, 1997). Acetylcholine is involved in voluntary movement, learning, memory, and sleep. | | | | Pharmacological agent prescribed to increasethe neurotransmitter: | List three possible side effects linked to this agent: | To increase the neurotransmitter in the body the supplement choline bitartrate and CDP-Choline and herbal agents ginseng and ginkgo biloba (Moore, 2013). | 1) Low blood pressure | | 2) Stomach ache | | 3) Increase perspiration and salivation (Moore, 2013) | Example of a neurological disorder, disease, or condition where this agent occurs | List possible risks associated with not taking this agent for the disorder, disease, or condition: | A severe autoimmune muscular disease by varying progressions of defects of the skeletal muscles in the body is known as myasthenia gravis.
P1 – explain the principal physiological perspectives There are different physiological perspectives which relates to the normal functioning of a human being. Some of the perspectives I will be talking about are Cognitive, Biological, Social learning, Humanistic, Psychodynamic and Behaviourists. Cognitive/information processing perspective – This perspective understands the way in which we process information, the internal process of their mind. This theory talks about the way that perception, attention, memory, language and thinking in humans, human intelligence and thinking and problem solving. This theory is discovering ways to learn more about the processes that underlie our ability to represent information about the world in memory, how language works and how we solve problems and also how we learn things.
In Audacity, what should you do if you want to see more detail in a sound wave? If you want to see in more detail of a sound wave you click the zoom button. Lesson 3 1. What is the phase of a waveform? A phrase of a waveform is the point where the wave is in its cycle.
The effects are alertness and arousal, and influences on the reward system. Anatomically, the noradrenergic neurons originate both in the locus coeruleus and the lateral tegmental field. The axons of the neurons in the locus
Axons of mitral cells pass directly back to the olfactory cortex on the ipsilateral side. Anterior commissure is a small commissure that connects the two halves of the olfactory system. Olfactory cortex is the portions of the cerebral cortex that receive direct projections from the olfactory bulb (via mitral cell axons) are collectively referred to as the olfactory cortex. It is located on the base of the frontal lobe and medial aspect of the temporal lobe. On the base of the frontal lobe it overlies the anterior perforated substance through which the striate arteries enter the interior of the brain.
Parietal lobe - responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness. Occipital lobe- responsible for processing information related to vision Cerebrum lobe - biggest part of the Brain its role is memory, attention, thought, and our consciousness, senses and movement. Hippocampus = responsible for memory forming, organizing and storing and emotions. 3. Explain why depression, delirium and age related memory impairment may be mistaken for dementia.
It’s one thing to propose the existence of a primary memory system. It’s something else again to find a primary memory system located in the dorsolateral frontal cortex of the brain (Pg. 31). Cognitive psychologists used localization to determine what areas of the brain enable functioning. Research helps understand the states of consciousness, sensory experiences, emotions, motivations, and more (Willingham, 2007).
Bathsheba Kabubi Psychology (SL) Essay 10(draft 1) Discuss the use of brain imaging technologies for investigating the relationship between biological processes and behaviour. Brain imaging technologies are used in psychology to examine the human brain. They are specifically useful in neuropsychology because it provides an opportunity to study the active brain. It allows researchers to see where specific brain processes take place. It also provides correlations between brain activity and behaviour.
