Introduction to course assessment 18 Module Structure - a module with a difference What you won’t do Exams Dissertations Multiple Choice Data Collection
course assessment 19 Module Structure - a module with a difference What you will do Listen to some lectures Read about something that interests you the most (a PDF library is provided to get you started) Think of an experiment that would advance our knowledge of that subject Price up your experiment Write up your experiment proposal X 3
course assessment - the form 22 Choose your equipment and participants
course assessment FAQ 24 What should the proposals contain? Each 2,500 word research proposal should detail the background, rationale, methodology and expected outcomes of one or more make-believe experiments investigating a particular HSI issue. The word limit is an absolute maximum and a set form should be used. Each proposal must be submitted 5 weeks after each mini lecture series. What is required?Imagination and a good understanding of a specific research area in HSI. Can I choose any topic? Yes, as long as it is related to the lecture material. Check with me if you are not sure. Can I invent any experiment? Yes, but within limits. You can use any equipment or participant groups you want, so long as you stay within a specified budget. Equipment and participants have a cost roughly relating to how rare that equipment or participant is in real life. You have a maximum of 1500 units to spend.
course assessment FAQ 25 What can we get from you? Practically nothing in terms of ideas for experiments, but periodic feedback will be given as well as some web-based support (in addition to lectures of course). I can tell you if an experiment is plausible and within the scope of the course and I can help with budget queries. 1 email rule. Anything else we should know? You will have to show that you understand the procedural and analysis requirements for any proposed experiments as well as having a solid rationale and sensible potential outcomes that are theoretically relevant to social neuroscience. If you don’t feel up to that you should bale out now. What else? All proposed experiments must be original (theoretically relevant modifications to existing paradigms are allowed, replications are not). What if my great idea gets published before I hand it in? You can bank ideas with me by email if you are worried that they might be stolen by real scientists.
course assessment FAQ 26 What you will write about Why it would be an interesting thing to study (background) What you would hope to find out (Q.’s to be answered) How you would do it (plan of investigation) How you would analyse it (details of data analysis) What you think you would find (expected outcomes) What could go wrong (details of difficulties foreseen) What it all means (future purpose and theoretical implications)
course assessment FAQ 27 How will it be marked? according to lab report guidelines in Handbook (this is not true) When will it be marked? soon after submission (this is true) When will I get my marks back? that is a very good question PROVISIONAL marks should be available 2-3 weeks after submission What kind of feedback can I get? Individual feedback will not be possible Group feedback between each submission
Course website - useful pages 28 www.psychology.nottingham.ac.uk/staff/rwn/C83SNR All handouts & lectures can be downloaded from the web Large print or full page versions can also be made Username: c8clhs (lowercase!!) Password: hsipfn Several very relevant journal articles and review articles are available as PDFs on the web-site This is not an exhaustive list. Further reading is freely available through internet and library resources Revision questions should be submitted through the web-site.
Course Reading 29 Recommended Books: None Best course material is source material (i.e. journal articles). Many are available from my web-page library. Many more available on request. They are: free up-to-date Vital for being on the cutting edge of research (which will help you get a good mark). *Good primer reading available on web page*

Introduction to cognitive social neuroscience Social cognitive neuroscience: An integrated interdisciplinary field asks questions about topics traditionally of interest to social psychologists (such as emotion regulation, attitude change, or stereotyping) using cognitive neuroscience methods (such as functional brain imaging and neuropsychological patient analysis) NB: This course will concentrate mainly on aspects of social interaction that are non-verbal and are concerned with the interpreting the actions and emotions of other people 31
D 32 Why do we want to know about brain activity? We already know that behaviour involves the brain (e.g. Gage, Tan, Bertino) brain localization can be helpful in solving psychological models Models use hypothetical representations and processes. Automatic process: The boy’s a fool Controlled process: Some of my best friends are presidents Hypothetical representation

Automatic process: The boy’s a fool Controlled process: Some of my best friends are lecturers Hypothetical representation
Except on Tuesdays Why do we want to know about brain activity? We can observe a behaviour and construct a hypothetical model to explain that behaviour (e.g. Bruce and Young face processing model) Evidence in support of models is based on whether they can account for behavioural data On the face of it, models work because they can explain observable behaviour And they can be modified to incorporate new, unusual behaviour Processing unit Visual input Observed behaviour 34
Problem - More than one model can explain the same data Visual input Visual input Face processing unit Fear P.U Anger P.U Emotion processing unit Fear Anger Fear Anger Two potential models for the processing of facial expressions of fear and anger so how do we tell which one is correct? 35
Visual input Visual input Face processing unit Fear P.U Anger P.U Emotion processing unit Fear Anger Fear Anger How do we differentiate between models? 36 Behavioural measures such as RT data Brain localization
37 Cognitive neuroscience methods Three main techniques Single Cell recording Animal studies Open head surgery Brain Imaging PET fMRI EEG MEG TMS Patient studies Disease Degeneration Head Trauma Stroke Congenital abnormality Psychiatric patients
lesion studies Patient ML Patient RM Problems Large lesions Up/downstream White matter etc. Overlay issues + monkey lesions 39
Brain imaging – PET & fMRI PET and fMRI provide indirect measures of blood flow (haemodynamic response) BOLD (Blood Oxygen Level Dependent) fMRI provides a measure of haemodynamic adjustments Good spatial resolution, poor temporal resolution Results often displayed on maps like these 41
Brain imaging 42 Functional brain imaging and lesion studies often try to localise constructs such as lexical access or motor sequence learning Localising the brain activity associated with a construct is compelling evidence for the psychological reality of the construct e.g. Theory of Mind. Subject. One mature Atlantic Salmon (Salmo salar) participated in the fMRI study. The salmon was approximately 18 inches long, weighed 3.8 lbs, and was not alive at the time of scanning. Task. The task administered to the salmon involved completing an open-ended mentalizing task. The salmon was shown a series of photographs depicting human individuals in social situations with a specified emotional valence. The salmon was asked to determine what emotion the individual in the photo must have been experiencing.
EEG/ERP EEG is a measurement of the electrical activity in the brain created when neurons fire ERPs are a type of EEG EEG measurement time-locked to an experimental event Good temporal resolution Poor spatial resolution 44
MEG (Magnetoencephalograpgy) Measurement of magnetic fields occurring outside the head as a result of naturally occurring electrical activity in the brain Better spatial resolution than EEG/ERP Relatively rare 45
46 Transcranial Magnetic Stimulation (TMS)? Uses electromagnetic induction to temporarily disrupt brain function Can be very focal Very high temporal resolution Can induce seizures + need to exercise caution with vulnerable populations

Summary 49 Social psychology is riddled with hypothetical models (as well as rubbish experiments and unexplored avenues of research). Knowledge about brain function can help differentiate between models Cognitive neuroscience provides information about brain function Social cognitive neuroscience is an integrated interdisciplinary field that asks questions about social psychology using cognitive neuroscience methods
