Research Investigation
The topics are set by the SQA, though the details of how the experiments are carried out are up to you. I like this year's topics - one is on the use of images to help with memory, and the other is on the effects of a 'stressor' on a bodily response such as heart rate. Both should be pretty straightforward to carry out and write up. Usually students find this part of the course enjoyable, so I hope it will be again this year.

Past Papers; textbooks
Working Memory
1) The model was proposed by Baddeley and Hitch in 1974
2) It is an alternative view of STM, which emphasises active processing (i.e. it doesn't see STM as a passive store of info).
3) WM is the part of our mind that we use for day-to-day tasks and problem solving
4) WM can achieve more than one task at once
5) The Central Executive is a system based on attention, and how your attention can be divided between tasks. It controls the other parts, which are known as 'slave systems'.
6) The Central Executive is modality-free, has a limited capacity, and is necessary for creative and non-routine processes.
7) Sound and language are mainly processed in the Phonological Loop, which has two parts...
8) The Articulatory Process or 'Inner Voice' is responsible for rehearsing words or numbers inside your head. It has a capacity of around two seconds. The Phonological Store is sometimes called the 'Inner Ear'.
9) The Visuo-spatial Sketchpad does routine visual processing, but is less well-researched. It is sometimes known as the 'Inner Eye'.
10) Recently, a new slave system, the Episodic Buffer, has been proposed. This is similar to Episodic LTM, except that it is temporary.
IRP again; memory
We're well underway with the topic of memory now - nearly finished it in fact. Well done on all the hard work, good homework tasks and practical work too. Next week we'll be looking at the last sub-topic, memory improvement strategies and mnemonics, which is always good fun.
I had mentioned before that your presentation topics could make IRP topics. It is worth noting that a topic such as 'schizophrenia' would lend itself to purely reading-based type of research. In contrast, some of the memory tasks we have done recently might give you an idea of how you could do an IRP based around a psychology experiment.
If you have a vague idea of something you'd like to do along these lines but haven't yet got a specific topic, why not email me about it.

Atypical Behaviour again; IRP
I will keep the posters to display in the future, but it occurred to me that the PPTs don't benefit from this. For this reason I intend to gather together as many as possible, and put them into a shared network folder for other students to view at their leisure.
I mentioned in the previous post that some aspect of the Atypical Behaviour topics could give rise to an IRP topic. Another possibility to bear in mind for the IRP could be doing something more experimental, along the lines of some of the memory experiments we have done so far, followed by a write-up.

Atypical Behaviour
As I said before, it would be great if you could take your research further - many of the topics would make excellent starting points for the IRP.

Another illusion

Illusions
Talking about illusions in class today - this is one of my favourite ones, and I think it works better on the screen than on paper:
Yes - believe it or not, squares 'A' and 'B' are exactly the same shade of grey.
Illusions like this help us to understand a key idea of the 'cognitive perspective' - the world that we percieve is to a large extent constructed by our mental processes. How we respond to objects and events can depend on our expectations and thought processes.
In this example, we expect square 'A' to be black and square 'B' to be white - so that is what we see!
Welcome!

The Higher Psychology exam 2008
I thought the exam paper was pretty reasonable. Section A was pretty good - nice chunky areas of the topics to talk about. Section B was an experiment which was great, especially as we had practice of answering similar Qs in your 2nd Prelim.
The section that stood out as most problematic was Conformity & Obedience. The first Q ('What is meant by conformity and obedience') was ok, but the other two were harder. For (b), 'consider factors which affect conformity...refer to relevant research evidence', I hope you thought to include situational factors such as group size, and individual factors such as age and gender. Certainly not an easy one. (C), on the ethical issues with obedience research, is perhaps more straightforward, but not something that many people would have prioritised in revision. However, bear in mind that pupils throughout the country would have the same problems with these questions!
The essay Q on Intelligence was always going to be a bit tough, but the topic was fairly predictable - theories of intelligence (aspect 1) - this hadn't come up as an essay Q before.
All in all, I thought it was as good as could be expected, and I hope you gave a good account of yourselves!!!!

Multiple intelligences
Multiple intelligences is a popular area of the topic intelligence, but there tend to be a lot of misunderstandings. Hope I can clarify a little:
The theory was proposed as a reaction against the idea of unitary intelligence, and the importance of IQ scores.
Gardiner (1983) felt that IQ was too simply defined and measured - short answers on a test could not accoutn for all types of intelligent behaviour.
If you compare two people, one might be less able in one area than the other, but the other might be stronger in another are of cognition.
Gardiner believes that everyone has a unique pattern of intelligences, a unique 'cognitive profile'.
Gardiner set out eight criteria for whether an ability or capacity should be defined as an intelligence, including:
- There are case studies of individuals exhibiting unusual talents in the capacity
- There is neurological evidence of areas of the brain specialized for the capacity
- The capacity has clear evolutionary relevance
- There exists a symbolic notation (e.g. written language, musical notation, choreography).
Seven intelligences were originally set out. An eigth, naturalistic intelligence, was added in 1999. Discussions are ongoing as to whether a ninth, existential intelligence, should be included in the theory.
Here's a more colourful version of the image from your booklet!Explanation: Reliability v's validity
Reliability and validity can be confusing. I will try to clarify.
Any kind of test or measure - IQ tests, exams, langauge tests - should be both reliable and valid.
Being reliable means that it gets consistent results. Two people with the same ability should get the same result. The same person tested on more than one occasion should get the same result.
The problem with making an IQ test reliable is that it is hard to know someone's intelligence level without testing them, and if you then test them again on the same test, they will do better because of practice. Test can be made more reliable by reducing elements of chance or guesswork.
Being valid means that it measures what it aims to measure. Surprisingly often, this is not the case. For example, you might fail a memory test because you ran out of time. However, it was supposed to be a test of memory, not a test of speed. An IQ test is supposed to measure intelligence. You could not give someone a science test and say that it measured their intelligence, because knowledge of science is (in principle) separate from intelligence.
The problem with making an IQ test valid is that nobody seems to agree what exactly intelligence is. This makes it hard to know what kind of questions to include. For example, some people would include verbal questions such as:
What is the odd one out - hat, coat, scarf, shelf
Other people might say that language ability is separate from intelligence. Also, the question above could be accused of being culturally biased, as not all cultures wear hats etc.
Culture
Most psychological research is done in North America and Europe, and theories are sometimes criticised for this - do the conclusions apply to other cultures around the world?
It used to be the case that in the unit 1 topics, you could get a tricky little 4 or 6-mark question on culture. However, the new format seems to make that less likely - I can't see a ten mark question on this coming up.
However, it would still be useful to know at least one piece of info or research for each topic that will allow you to show an awareness of cross-cultural issues. This will help you pick up extra marks, especially A&E marks, and give that 'WOW' factor to the examiner by knowing things that most candidates don't know!
Here are some possibilities:
Memory: a lot of our long-term memories form culture-based bundles of knowledge called schemas. Bartlett (1932) showed how people tend to distort info from other cultures. Any good theory of LTM must take culture into account.
Early Socialisation: Morelli & Tronick (1992) gave evidence that 'stages of attachment' apply to an African hunter-gatherer tribe, despite differences in child-rearing. A strength of Ainsworth's theory of attachment types (secure, avoidant, resistant) is that she studied Ugandan children as well as American.
Stress: Social support is one of the strategies for reducing stress. Kim & McKenry (1998) studied social support in the USA, and found that ethnic minorities (e.g. black, hispanic) tended to have better support from their parents/children than the white majority.
Intelligence: The main issue to be aware of is cultural bias in IQ testing. Gould (1982) disputed evidence of racial differences in IQ, as cultural background and knowledge of English were confounding variables.
Textbooks
I don't mind people borrowing them, but there are quite a few missing, and obviously I do need them for next year. Please pass them back when you can, you won't get into trouble.
Thank you!

Explanation - sensory memory
Sensory memory (SM) is the mind's ability to store information from the senses for very brief periods before it is processed.
Each sense is thought to have a separate 'sensory store', but the most well-known are the vision-based store, 'iconic memory', and the hearing-based store, 'echoic memory'.
Iconic memory lasts for 0.5 seconds, and echoic memory lasts for 2 seconds.
We often experience this, when somebody speaks to us & we are not paying attention. If we then focus on what they said, we can still hear a kind of shadow of what they said ringing in our ears, and are able to process it. This can be very useful!
Sperling (1960) studied the capacity of iconic memory by presenting visual items very briefly. The capacity initially appeared small, less than that of STM, but he later found using a 'cued recall' technique that a lot of information is taken in, but it fades too fast for people to be able to report it all. By the time they have recalled the first three or four items, the rest has faded from their 'mind's eye'. By cuing Ps to recall just one line from a three line display, recall rose to 75% from a 12 item display.
A&E marks again
I've already posted on this topic, but just to highlight again, underline, circle in red pen and otherwise draw to your attention, two especially important points:
1) You can get A&E marks for giving real-world examples.
2nd Prelim (again)
If you haven't seen me and want to know how you did, send me an email and I'll reply with your grade, although I'd rather see you in person and go over it.
Explanation: Decay theory of forgetting
The basic idea of decay is that when we encode a memory, a structural change takes place in the brain. Hebb (1949) argued that this trace (sometimes called an 'engram') is delicate, and liable to disruption over time unless further learning takes place. So, in short, if we don't practice/rehease learning, then it will fade and be forgotten. Decay means fading/crumbling of memories over a period of time.
However, research shows that procedural LTMs - skills such as driving a car - are not forgotten even if not used for many years. Additionally, memories sometimes spontaneously reappear, in dreams or if you have a bump on the head. This phenomenon suggests that the engram has not actually decayed, but some other process has caused forgetting.
An early piece of research by Jenkins & Dallenbach (1924) gave participants ten nonsense syllables to learn. Some participants went to sleep (this is a 'do nothing - no interference' condition) and others carried on with normal activities. The period spent asleep didn't result in greater forgetting, leading them to conclude that forgetting in LTM is not due to decay but due to interference of new information.
Similarly, Baddeley & Hitch looked at forgetting in rugby players. Some participants had played a large number of games over a season, and others had played fewer due to injury or suspension. The researchers found that the key variable affecting recall was the number of games played - again supporting the idea that memories suffer from interference rather than decay.
Evidence for decay in STM is better - Peterson & Peterson (1959) found that forgetting in STM was a function of time, with recall falling sharply over the course of 30 seconds. However, even this kind of research does not prove the role of decay. This is because to allow for other factors (especially displacement/interference), the participants would have to be doing nothing during the time period. In fact, they were doing a distraction task (counting backwards) to prevent them from rehearsing the items.

Early socialisation vids
Harlow's monkeys:
http://www.youtube.com/watch?v=fLrBrk9DXVk
Great illustration of how the monkey goes to the wire surrogate to feed, but is comforted by the cloth one.
Separation anxiety:
http://www.youtube.com/watch?v=Y6QtuU1L_A8&feature=related
Similar to the 'strange situation', this shows an approx 1 year old child upset with a stranger, but easily comforted by an attachment figure (his dad, we assume). I agree with scantysanwiches, it seems to be a secure attachment!
Parenting styles - website
A bit weaker is most people's ability to discuss the impact of the different styles on children. If you're doing this topic, the following article is definitely worth a look:
http://www.athealth.com/Practitioner/ceduc/parentingstyles.html
Like with other areas, an answer is going to be much stronger if you can accurately refer to a research finding.

Explanation: Factor models & information-processing models of intelligence
What is the difference between 'factor' & 'information-processing' models of intelligence? Which group does Gardiner's model go in?
Bear in mind that people do not universally agree what intelligence is. Some people decided that the best approach would be to give people ability tests, and use statistics to see what patterns emerge. The theory can then built from that information. This is the case with factor models. The main statistical test used is Spearman's 'factor analysis', and the term factor models derives from this test.
One problem with this is that it can depend on what tests you give to your research participants. Spearman (1904) found a single 'g' (general) factor, but Thurstone (1938) found 7 factors. Also, it only shows that certain factors exist, it doesn't tell us anything about how these processes work, or how performance could be improved.
Information-processing (or 'cognitive') models are not based on testing - instead they make models of how people process information & solve problems.
Cognitive psychologists have looked into various abilities such as reaction time, working memory, ability to retrive words from LTM, and ability to make accurate comaprisons. Rather like models of memory that we have studied, models of intelligence in this approach are built up, and include various elements that link together.
Gardiner's model of multiple intelligences doesn't fit neatly into either group. Gardiner places a lot of emphasis on neuroscience - studies of the brain and brain damage. He is also very interested in 'savants' - profoundly retarded people who have one special ability e.g. drawing or mathematics. Many people in psychology are sceptical of Gardiner's approach, which seems to rely a lot on assumptions rather than research.
If you have to place it in a category, then call it an information-processing theory, because it has developed as part of contemporary cognitive psychology. Besides, it's definitely not a factor model, as it doesn't use ability testing or factor analysis.
Exam info: A&E marks
I thought it would be useful to copy from the course arrangement document the SQA's description of what these marks should be awarded for, and this is in italics below. Three of the main points which you may not have realised:
You can get A&E marks for giving real-world examples
You can get A&E marks for explaining parts of a model and how they work together
You can get A&E marks for comparing and contrasting
Remember that A%E makes up 40% of the exam marks overall, but check carefully the mark allocation for each question before you answer it.
Analysis will involve, for example:
♦ explanation of components of a behaviour or mental process and the relationship between
these
♦ description of factors affecting behaviours and mental processes
♦ discussion of origins and development of behaviours and mental processes
♦ interpretation of research findings and conclusions in relation to relevant theory
♦ the ability to discuss psychological phenomena from alternative theoretical perspectives
♦ comparison of evidence from different cultural contexts
♦ integration of knowledge from different psychological areas, and of new information with
already-existing knowledge
♦ identification of common underlying themes, such as nature/nurture interaction; application
of knowledge in a new context, or in a situation in everyday life
Evaluation may include aspects of analysis as well as the ability:
♦ to weigh up the strengths and weaknesses of psychological theories, concepts, research
evidence, research methodology, and psychological applications
♦ to compare and contrast theories
♦ to discuss ethical issues in psychological research and applications

Revision classes
I know most of you would rather avoid anything too early, too late, or too often, so can I suggest we go for a once a week, 10.30 to 12.30 session? As follows:
Thursday 15th May, 10.30, Room B43 (day before the 2nd Prelim)
Thursday 22nd May, 10.30, Room B43 (to return 2nd prelim scripts)
Thursday 29th May, 10.30, Room B43
Monday 2nd June, 10.30, Room B43 (2 days before exam)
Obviously if you have an exam to go to the same day then that comes first, but otherwise I do expect people to turn up for these sessions. In the past I have found it makes a big difference, with people who regularly attend May revision classes doing well in the exam.
2nd Prelim
Previous exam questions will be included in prelims, so it's worth going through the past papers as preparation.
Just to make it completely clear, the 2nd prelim is the one and only piece of evidence I will submit as appeals evidence, so it is extremely important that you make it on Friday and give a good account of yourselves. Without a good pass in the 2nd prelim, no appeal can be submitted.

Past papers
The situation is that the past papers are not currently published by Leckie and Leckie, mainly because the revised version of the course has not been running for long enough. What I can do instead is photocopy my copies of these papers for you. Also, the marking schemes are available for free on the SQA website, and I have saved these onto the the school network.
I also have an updated version of the Specimen Question Paper for Higher Psychology available for you, and again the marking scheme is on the network. This is the only publiched paper which has the new-format Section A. Take note that the past papers from 2005-2007 contain old-format Section A, with only 2 of the 3 topics included. From 2008 onwards, this section will contain all three topics, from which you can choose 2 to answer. Also, these questions will all be either 10+10 marks, or 8+12 marks.
