Here are the best blogs in each of the following respective areas, according to me.

There are some sub-fields I know nothing about (clinical topics mainly), so this list is not comprehensive in that regard.

I’ll update this as time goes by. Feel free to repost this on your own website to spread the word about these excellent resources.

Critical Thinking

Bad Science – Ben Goldacre’s site. Not a psychology site actually, but if you’re a psychology student you should immediately subscribe to Ben’s blog and let his critical attitude rub off on you through the power of web-osmosis.

If you’re doing a study using two or more groups, you’ve got two options: You can use different people in each group (between participants design), or you can use the same participants in each group (within participants design). There are pros and cons to each.

Say I’m an office manager and I want to measure the effect of distraction on workplace performance. My workers always have that damned radio playing all those cheesy love songs, and I think it’s distracting them and costing me valuable profit. So I hire a researcher to find out for sure.

He might use a between participants design. On one floor of my office he bans the radio. On another floor, he let’s them carry on as usual. At the end of the week, we work out which floor got the most work done. Pretty simple.

Or, he might use a within participants design. He only looks at one floor. For a week he measures their workrate while the radio is there, then the week after he takes it away and measures workrate again.

What’s the best way?

There’s no right or wrong answer. If he used a between participants design, he’s got different people on each floor. Maybe one floor is populated by people who are better workers than the other floor. To truly test the effect of the radio, and nothing else, the conditions – and the people – in the test would have to be exactly the same. Normally in psychology, researchers try to get large numbers of people in each group, and assign people randomly to each one. That way it’s expected that, since most human traits fall on a normal distribution, the groups will be pretty similar to each other on average.

But to get them exactly the same, you’d have to use the same people! That’s a within participants design. This brings it’s own problems with it. In this particular example, there might be temporal effects – differences in the environment week by week. For instance, maybe there were an unusually high number of birthdays in the office on the second week, and they went out celebrating a few times, leaving them tired at work. Or maybe on the first week, they were a bit nervous about having a researcher watching over them, but by the second one they had gotten over it.

Temporal effects aren’t limited to within participants designs of course – in a between participants design you might test the groups at different times; although you should not do this unless you have no other choice, to avoid these temporal effects.

Within participants designs are also vulnerable to something called practice effects. If I’m measuring the effect of caffeine on some cognitive ability, such as working memory, I might test people when they first step into the lab, then give them a triple espresso, and test them again.

Is this a between or within participants design? It’s within participants – testing the same people twice. But, the second time they do the test they know what to expect; they have had a little practice. So they might improve on the second test purely through this practice effect, rather than the caffeine.

Alternatively, maybe the results were influenced in the opposite direction – maybe they got bored of doing the test twice and didn’t put as much effort in the second time around.

There’s a way of getting around this – counterbalancing. You split the sample in two, and half of them would get the espresso before the first test, while the other half would get it before the second test. In this case you’d have to leave a few hours between tests so that the caffeine wears off, but both conditions – with caffeine and without caffeine – would be equally susceptible to practice effects, so we can be more certain that any difference is due to the effect of the caffeine.

Once more, just to clarify

In a between participants design, a given participant is allocated to one group or the other, but not both.

In a within subjects design, a given participant is allocated to both groups.

Advantages of between participants design:

Help to avoid practice effects and other ‘carry-over’ problems that result from taking the same test twice.

Is possible to test both groups at the same time.

Disadvantages of between participants design:

Individual differences may vary between the groups

Vulnerable to group assignment bias (though you would use random assignment wherever possible to compensate)

Advantages of within participants design:

Half the number of participants need to be recruited

They offer closer matching of the individual differences of the participants.

Disadvantages of within participants design:

Practice and other ‘carry-over’ effects may contaminate the results (though you would use counterbalancing where possible to compensate)

Visualising this in SPSS

When you’re putting data into SPSS, a row always indicates a single participant. Data from two different participants will never appear on the same row. Therefore, in a within participants design, our coffee experiment would have two columns for our data – one for with caffeine, one for without.

But, if we had used a between participants design, we would have ONE column for the data, plus another column saying which group that participant was in.

Alternative names

Between participants is also known as independent measures design, or between subjects design.

Within participants is also known as repeated measures design, or within subjects design.

Are you finding the stats section of your course a little difficult? It’s hard to understand at first, but I’ve explained the bulk of what you need to know in plain English, in the study guide. Have a look.

Whether you’re writing a novel, a blog, or an essay, the biggest problem has to be writer’s block. It’s so annoying when you’ve actually gotten past the initial procrastination hurdle (not an easy task in itself), you’re sat at your desk and you WANT to write – but it’s just not coming out. Or, what is coming out isn’t to your liking.

Trust me, I know how that feels; I started this blog post in 2005.

Here are a few tips you can try to give your creativity a little boost.

1) Get the right emotions for the job

Our emotions serve evolutionarily adapted purposes. We have different emotions because they each solve different evolutionary problems. Anger helps to stop people transgressing against us, love helps us keep a mate, fear keeps us out of danger, and so on. Because they are specialised, emotions have different effects on our perceptual system, and the ways we think. ‘Negative’ emotions tend to narrow our though-action repertoire, while ‘positive’ emotions tend to broaden them (Fredrickson, 2001 – PDF).

In other words, when you’re in a lower mood, you’re more likely to look at the little details, when your mood is high, you’re see the bigger picture and be more creative.

So whenever you’re brainstorming or coming up with new ideas, boost your mood with something uplifting, heart warming, or side-splitting. I like this.

Whenever you’re editing or proof-reading, put some downbeat music on, and get to work.

(We might also suppose that continuing a long argument with your spouse is a bad idea – you’re both focusing too much on the things that put you into that negative state. Sleep on it and discuss in the morning.)

2) Take breaks

Whenever you’re doing work that requires focused, mental effort, you’re draining your mental willpower reserves. Once these are depleted, performance suffers and you suddenly can’t be bothered to work. Take regular breaks and do something that requires no effort to attend to – spending time in nature has proven to be a useful exercise to this end (See the extensive work of the Kaplans). Also, make sure you don’t go hungry while working – the fuel that willpower runs on is glucose (Gailliot and Baumeister, 2007) – empty stomach equals poorer mental performance.

3) Use novelty to your advantage

Short answer: If you want a novel idea, expose your brain to novelty.

Long answer: The area of the brain associated with novelty is thought to be the substantia nigra/ventral tegmental area (SN/VTA). The VTA is part of the dopamine system, in other words, the reward system. When we perceive novelty, our brain signals us to explore, because it is always looking for rewards. The brain likes novelty.

What’s more, these brain areas are connected to the hippocampus, which is involved in learning. You can see where I’m going with this; enhanced learning might occur in the context of novelty. On top of that, a novel environment exposes you to a different set of priming, which themselves trigger different areas in your brain.

There’s the science, here’s the simple advice – go somewhere new to write. Try a park, a library, a coffee shop you’ve never been to. Try a car park, a zoo, a big wheel, try wearing different clothes, talking to different people. Use novelty to your advantage and see if your brain doesn’t come up with some new ideas.

4) Try the SCAMPER method

Luciano Passuello of LiteMind discusses the SCAMPER method of creative problem solving. This is going to be more effective when you have a specific writing problem you are ’stuck’ on. It is essentially a list of questions which help you to look at the problem from 7 different angles, each represented by the SCAMPER acronym. Not all of these angles will be appropriate to your specific writing problem, but I’ve found it really useful at various times. I’m interested to hear how you get on with this method, so let me know if you use it – leave a comment with your experiences!

Get to it

I’m certain that by using one or more or these techniques (all four if necessary) you’ll be able to make at least SOME headway on your writing. Let me know how you get on!
