If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour, pink.
Pink dots flashing
However if you stare at the black ‘+ ‘ in the centre, the moving dot turns to green.
Now, concentrate on the black ‘ +’ in the centre of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.
It’s amazing how our brain works. There really is no green dot, and the pink ones really don’t disappear. This should be proof enough, we don’t always see what we think we see.

The London Dungeon offers you to chance to be transported back ‘to the darkest moments in the capital’s history … live actors, shows, two rides and interactive special effects ensure that you face your fears head on in this unique ninety minute experience.’ Two psychologists (Tim Valentine and Jan Mesout of Goldsmith’s College, University of London) had the great idea to utilise this experience as an opportunity to ethically test EWT in a stressful context.In the Labyrinth of the Lost a hooded actor jumps out on unsuspecting visitors, blocking their path – which offered the psychologists the opportunity to ask people, after they emerged from the labyrith, if they could identify the man from a set of photographs. In total they interviewed 56 people and found that those who reported feeling more anxious about the labyrinth experience were less accurate in their identification – 17% of high anxiety participants were correct compared with 75% of low anxiety participants. This demonstrates the negtive effects of anxiety on EWT.A separate investigation showed that self-reports of anxiety were positively correlated with physiological arousal in the labyrinth.

No excuses …

Several times it has been suggested that playing video/computer games trains the brain to become cognitively more skilled. This doesn’t refer to hand-eye coordination, but to memory, thinking, reasoning, decision-making skills. However this hypothesis has been challenged by researchers at the University of Illinois who had non-gamers as participants. These individuals played one of three video games and after more than 20 (non-consecutive!) hours  gaming the participants took some psychological tests. Unfortunately they showed no increase in memory skills or multitasking ability as had previously been predicted, though it is still possible that this type of gaming could improve concentration even if other cognitive skills don’t benefit.

So is this doom and gloom for gamers’ self-worth? Not really, as we all know that one study proves nothing, and a few hours of gaming is unlikely to rewire the brain in any meaningful way. Of course, as the lead researcher Boot says, “Perhaps individuals with superior abilities are more likely to choose video gaming as an activity in the first place.”

Am I normal?

BBC radio 4 has been running an interesting series called Am I normal? One of the programmes looks at Working Memory and what is normal in terms of how people can use there working memories. Have a look here. Research suggests that working meory is the single most important predictor of later academic success – the big question then is, how can you improve your working memory?

One of a collection of ‘spirit’ photographs taken by the medium William Hope.

He produced such photos for bereaved individuals, desperate to contact their loved ones. His services were especially in demand by those who had lost relatives in World War One.

In the 1920′s he was accused of faking such photos by superimposing other images upon the original.

I don’t know what this sad collection of photos tells us about parapsychology -beyond warning about a misplaced faith in technology and a desperate desire for something to be ‘out there’…….

In the AS Complete Companion the arrows were incorrectly drawn in the diagram. The correct version is shown below and will appear in more recent reprints.cc-diagram-p12.jpg

An Australian radio programme has recently broadcast a programme (11 October 2008) which went in search of some of the original subjects and interviewed them. There is an option which allows you to download it too! Here’s the link. There are also audio clips from the original experiment. Quite fascinating.

You can also read interviews with Milgram’s subjects in the book by Laren Slater called Opening Skinner’s Box.

Over FIFTY psychological explanations of learning – all in one place…..

I wonder if some kind of advanced form of theoretical systematic review could iron out all of the inevitable overlaps and maybe shake it all down to a manageable three or four key factors? – I wonder what they’d be? Would the ’key’ theorists everybody has heard of play the biggest role? Or would some obscure approach that seldom emerges in lectures outside of a PhD course prove to have the most robust supporting evidence? – I often feel a lot of the classics we teach, in every field of psychology, can carry a weight or ‘historical resonance’ far beyond the quality of the actual research results….

My money would be on Vygotsky – not for any reason other than it feels right to me (You might get a mark for this very feeling in an exam if you call it ‘intuitive appeal’). For example, I like his idea of ‘scaffolding’ :

Instructional scaffolding is the provision of sufficient supports to promote learning when concepts and skills are being first introduced to students. These supports may include:

These supports are gradually removed as students develop autonomous learning strategies, thus promoting their own cognitive, affective and psychomotor learning skills and knowledge. Teachers help the students master a task or a concept by providing support. The support can take many forms such as outlines, recommended documents, storyboards, or key questions.

- building a tower of knowledge together with a nudge and a prod – shoring up this bit, talking up that bit onto a firmer footing. It’s a pleasingly rugged, masculine model of teaching- Like the guys who scaffolded our place: Roll up in a van whistling a cheery tune, throw up a rough structure for students to build their knowledge skywards, knock off mid-afternoon, never come back to take it down again….
