Localisation of Function and Hemispheric Lateralisation in Psychology
This document... Show more
Hemispheric lateralisation in psychology refers to the functional differences between the two brain hemispheres. This concept is a key topic in AQA A-level Psychology, particularly in the study of biopsychology.
Definition: Hemispheric lateralisation is the idea that the two brain hemispheres are functionally different, with certain processes and behaviors mainly controlled by one hemisphere.
The document outlines the key features of hemispheric lateralisation:
Left hemisphere dominance:
Right hemisphere dominance:
Highlight: Information received in one hemisphere is sent to the other through bundles of nerve fibers, such as the corpus callosum.
The concept of hemispheric lateralisation was derived from studies on split-brain patients, typically those with epilepsy. In these patients, surgeons cut the corpus callosum to prevent violent activity from crossing between hemispheres.
The document presents several critical evaluations (AO3 points) regarding hemispheric lateralisation:
Lateralisation increases neural processing activity:
Example: Rogers et al. found that in domestic chickens, lateralisation enhanced the ability to perform two tasks simultaneously: finding food and being vigilant for predators.
Lateralisation changes with age:
Quote: "Szaflarki et al found language was more lateralised with increasing age in children but after 25 it decreased with each decade of life."
These points provide valuable insights for students preparing to discuss localisation of function in the brain (16 marks) or answer questions about hemispheric lateralisation in A-level Psychology.
Localisation of function in psychology refers to the principle that certain functions in the brain have specific locations. This concept is crucial for understanding brain organization and function in AQA A-level Psychology.
Definition: Localisation of function is the principle that certain functions in the brain have specific locations.
Before the advent of brain imaging techniques, much of our knowledge about brain function came from case studies. One famous example is the case of Phineas Gage, a railroad worker in 1848 who survived a severe brain injury.
Example: Phineas Gage's case demonstrated the role of the frontal lobe in personality and behavior. After an accident caused damage to his frontal lobe, his temperament changed significantly.
The document outlines several key areas of the brain and their functions:
Visual Centers:
Motor Cortex:
Somatosensory Cortex:
Auditory Centers:
Language Areas:
Highlight: Damage to Broca's area leads to Broca's aphasia, while damage to Wernicke's area results in Wernicke's aphasia.
The document also presents several critical evaluations (AO3 points) regarding localisation of function in the brain:
Vocabulary: Equipotentiality refers to the brain's ability to transfer functional memory from damaged areas to undamaged areas.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
