On voice neurocognitive psychologists and diagrams

On Tuesday, my sort of supervisor showed me what she'd done to my data the other day to put in her own paper. It was this intelligent and beautiful rainbow spectrum of a graph, all blue, red and yellow, and where data overlapped it became purple and orange... it was preeetty! And it was the data that I'd collected! Sadly I won't be using it for my own project cos that would feel too much like cheating. Turned out she wasn't the only working on pretty diagrams. That same morning, one of the other francophones in the lab also showed me his crazy complex multiple graph diagrams that he'd been creating. And then yesterday (after a right cuffufle of forgetting the right usb stick with the version of my project that I'd been intensively working on over the last couple of days) I got some highly useful feedback from my actual supervisor.
At least half of what he said could be condensed into this:-
- "Put in some cool diagrams here and here and here and here"
(it may have been a summary of what he said but I assure you, the word "cool" made an appearance on several occasions). So I had a go at some "cool" diagrams today. I made a reasonable effort I think, but none of them come even close to the rainbow spectrum graph I saw on Tuesday :( siiiigh...

Lessons for the week:
- Programming matlab is a useful skill to learn
- Voice neurocognitive psychologists like "cool" diagrams
- Never put your usb stick in your jeans pocket so you don't lose it. You will inevitably forget to take it out the next day

Man am I becoming geeky... see what final year is doing to me!

to foveate or not to foveate?

"Humans do not stare at scenes. They foveate. Their eyes dart about the scene at locations of interest during the analysis of the scene. Except for special cases, humans tend to focus on corners and edges of important objects of the scene." Jason Kinser, Institute for BioScience, Bionformatics, Biotechnology

We don't process everything we see. And that's not surprising really since we wouldn't get anywhere or do anything if we were constantly processing everything that's round about us. However that can sometimes result in confusion and/or misinterpretation. I did a presentation on how this kind of misintepretation manifests itself in language illusions on Friday. Let me demonstrate.

How many did each kind of animal did Moses put on the ark?
.........................

Did you get it? Did you say two? Or did you see the anomaly? If so, nice work because most people don't and this is known as the Moses Illusion and it's an example of "shallow processing" (what linguists call foveation). So why am I waffling about this other than to fulfil my geeky inclinations? Well today I was thinking about how much of a conscious foveator I am. How I so often only critically evaluate what I find relatively easy to understand because I am scared of the stuff I find more difficult to understand. How I so often see what I want to see and not what I'd prefer not to see. And that applies to everything, from bits of the bible I can't get my head around and would prefer to avoid, to things going on in another part of the world or even part of my city I prefer to remain blissfully unware of. But I specifically want to talk about the way in which I read the bible.
In order to avoid misinterpretation surely we need the full picture. So many mistakes have been made in the past, and we are still unclear on things because we are unware of the full context of a statement within the bible and in the era it was written in. Shouldn't we need to at least be aware of all these things so that we might understand the bible more fully?

But where does the balance lie between, one the one hand, questioning things, finding reason and understanding behind what we believe and on the other hand, knowing that God is God, that His wisdom is far above and beyond us and that we won't have all the answers in this lifetime? It's one of those "to what extent" questions that seem to crop all the time. I think it's easy to lean either too much to one side or the other. I definitely lean in the foveating direction i.e "I don't have all the answers so why bother too much about it?" but it isn't enough. Especially when I get interrogatively questioned about my faith.
I've leaned the other way in the past too; trying to process too much at once and as a result getting tied up and confused with trivial issues. To the point where it has gotten in the way of my ability to see and do and think straight in other areas of life. I think experiences like that may have scared me off deeply questioning things... but then maybe I've been questioning in the wrong way before.
I've been reading this passage over and over again the last few days, and something is starting to click in my head. We have God's Spirit in us, He gives us understanding, He gives us knowledge and the Spirit is key to that. But what kind of knowledge is that? I do know He enables to know Jesus and that He enables to understand God's plan for salvation so we can accept it and communicate it to others. I do know that He helps us grapple with the kind of knowledge that results in us having everything we need for life and godliness and that knowledge for the sake of knowledge is futile. But is that knowledge and understanding of the more difficult concepts, having a grip on prophecies that scholars have studied for years? Or is it just a grasp on concepts such as grace (not that those are especially simple)? Does the Spirit help us gain academic knowledge; the kind of apologetics that go way over my head or knowledge as in knowing God as a father, lord and friend? Should we as Christians know the bible inside out from cover to cover, or is it ok to skim the bits that we "may never understand" like certain prophecies or parts of Revelation?

That's a lot of questions and this probably makes for muddy reading. But if you do get through this I would appreciate any thoughts you might have on the matter. I'm kinda unsure...

Remember what you have seen with your own eyes

Anyone else get frustrated by their memory sometimes? I remember silly things like car number plates, phonenumbers, childhood memories from the waybackdistantpast, birthdays of people I've lost touch with, people's names who I meet once and never see again... but then I forget many other things that I should remember, like to fill in important forms, deadlines, vocabulary in french, that I was meant to clean the bathroom the other day, names of people I see everyday... my dad always called it my "selective memory"...

I wonder if we really do choose to forget or remember or not... I don't find that to always be the case.

Hermann Ebbinghaus, a psychologist (or scientist if you prefer ;) ) discovered this ... the forgetting curve.

He discovered, or rather (as most psychologists seems to do), put into a theory, that forgetting; memory decline, is exponential in nature, as illustrated in the graph. A person learns a piece of material, and as time goes on, slowly their retention of the information declines. Obviously there is some variation in this, some people coughBreakeycoughPottercough have unusual memories allowing them to view material and retain more information for longer periods of time and others can sometimes view something and seem to instantly forget it yet this curve seems to generally be the case quand-même. According to the studies and curve we never completely forget everything we learned, but we don't retain very much of it.

This however is dramatically changed when the learned material is repeatedly reviewed. Sadly not being the Glasgow uni library right now means I cannot access the Web of Knowledge which I relied on so heavily in first and second year of psychology, and thus cannot illustrate the significant effect it has with with another beautiful graph. But I'm sure you would probably agree, it seems like common sense to me...

Now I have been experiencing uncharacteristic bouts of anxiety of late. Anxiety about the future more than anything else, both near and far-off... and I blame this on the forgetting curve.

Because I know God has been faithful to me throughout my life! When I look back, I see so evidently how He has taken care of me... The Lord's my Shepherd, I shall not be in want. Even when I've least expected it, that has been the case! Oh I was nervous before I came to France all right, and yet He has taken care of my every need and exceeded them in countless ways! So why can't I trust Him with the unknown this time?!

Because I forget who He is and what He has done for me... Check out the number of times the word "Remember" features in the book Deuteronomy! Clearly the Israelites needed to remember these things, and yet the history told in the bible tells us the Israelites forgot them all the time. I'd like to think I'm different... but life and silly anxiety and the Bible and even the science of psychology all seem to suggest that I'm really not... not really at all...

So I'm blogging this as a general reminder, not least to myself, to look at the past, at our own lives, at each others lives, at the bible, and to remember who God is and what He has done... what we have seen with our own eyes...
