<strong>PDTE</strong> AGM MEETING In SPAIN 25 – 26 September 2010<br />

What is memory?<br />

Memory is an accumulation of things that<br />

have been learnt, or experiences that have<br />

been experienced and that are stored in<br />

the brain.<br />

This includes facts, events, spatial mapping<br />

(where to find things), physical processes<br />

/ motor skills (how to do activities)<br />

Your brain has stored a range of different<br />

facts — what you had for breakfast yesterday,<br />

the date you were born or that Paris<br />

is the capital of France and Helsinki is the<br />

capital of Finland.<br />

SPATIAL MAPPING just means where<br />

things are in life, where you find things,<br />

where the bathroom is, how you get from<br />

home to work or how you get from home to<br />

the supermarket.<br />

Also, you remember how to do things.<br />

PHYSICAL PROCESSES are what we call<br />

motor skills, how to do things like swim or<br />

jump or brush your teeth, or play the piano<br />

or drive a car.<br />

All of these things make up what we call<br />

memory.<br />

Types of dog memory<br />

MEMORY MATTERS<br />

Understanding memory and its effects on behaviour modification in the dog<br />

As humans we have two main types of<br />

memory:<br />

1) DECLARATIVE MEMORY.<br />

That means that we can state, or declare,<br />

certain facts.<br />

• Semantic memory (facts / figures)<br />

Semantic memory is memory concerning<br />

specific facts such as Helsinki being the<br />

capital of Finland, or that the next Olympic<br />

games is London 2012. You know (hopefully!)<br />

that 2 x 2 = 4 and how to tell the<br />

time from looking at a clock face.<br />

As far as we can tell dogs do not have<br />

semantic memory.<br />

• Episodic memory (events)<br />

Also part of declarative memory, things<br />

we can declare, is EPISODIC MEMORY.<br />

This refers to episodes, things that have<br />

happened to us or to those around us.<br />

The simple word for that is “events”. So<br />

you may remember your 25th birthday or<br />

your first day at school, or your wedding.<br />

Amber Batson, BVetMed MRCVS, ENGLAND<br />

All this is part of your declarative memory.<br />

Dogs have this type of memory, we may<br />

not know the exact details of an event they<br />

remember but we all know dogs remember<br />

events that happen to them.<br />

2) PROCEDURAL MEMORY<br />

This includes motor skills and emotional<br />

responses.<br />

• Motor skills<br />

Playing tennis, for example, is a physical<br />

skill. You have to learn how to throw a<br />

ball up and how to swing a racket. It is a<br />

physical skill to learn to ride a bicycle or<br />

a horse, or drive a car, or simply to climb<br />

stairs.<br />

• Emotional responses<br />

Emotional responses, like when you are<br />

really scared, involve a physical process<br />

like running away, or hiding, known as fight<br />

or flight. Emotional responses are part of<br />

procedural memory because they involve<br />

procedures, things that we do. And this is<br />

very relevant because dogs have these<br />

types of memories too.<br />

To recap, then, as far as we know dogs<br />

do not have semantic memory. It is very,<br />

very hard to prove that dogs remember<br />

facts or figures. Nobody has yet demonstrated<br />

that dogs can learn multiplication<br />

or addition. They might have a response,<br />

but they don’t seem to hold the fact in their<br />

head. They don’t know that the capital of<br />

Germany is Berlin.<br />

But they do have episodic memory; they<br />

have event memory and they do have motor<br />

skills and emotional responses, which<br />

are procedural memory. A dog definitely<br />

remembers being beaten up by a cat as an<br />

event! That is declarative memory. They<br />

remember having had a painful injection<br />

at the vet’s. Equally, they can learn motor<br />

skills like offering a paw or going through<br />

weave bars or catching a rabbit. They also<br />

have emotional fight or flight responses.<br />

They remember being chased by a horse,<br />

but they also knew at that moment how to<br />

run away from it.<br />

Dogs can learn a whole range of cues to<br />

certain activities. They can learn how to<br />

negotiate agility courses. For example, a<br />

dog can easily run under the agility bar,<br />

but he has learnt that in order to get a<br />

reward (reinforcement) — whatever that<br />

reinforcement is — he should jump over<br />

the bar. We’ve been able to teach dogs to<br />

find drugs, and they know that if they find<br />

the drug, they will get a reward (not the<br />

drug). We have taught them to be obedience<br />

tasks, agility tasks and even to be<br />

assistance dogs – letting us know when<br />

the phone rings, picking things up, moving<br />

things around.<br />

Therefore, if we understand how memory<br />

works in dogs, we can be better trainers.<br />

It means we can be better at fixing and resolving<br />

learnt undesirable behaviours. For<br />

example, say I don’t want my dog to jump<br />

up anymore. I want it to keep all its feet<br />

on the floor when I come home from work,<br />

I teach it a new behaviour - a new thing,<br />

a new memory. We’ll be better placed to<br />

fix behavioural problems if we understand<br />

how they got the behaviour in the first<br />

place — why they have a memory that<br />

causes a problem and very importantly, we<br />

might even be able to prevent behavioural<br />

problems by affecting their memories as<br />

well.<br />

We also have something called SHORT-<br />

TERM MEMORY and something called<br />

LONG-TERM MEMORY.<br />

THE HERE AND NOW – Short-term<br />

memory<br />

Short-term memory is information that’s<br />

coming in right now from the environment<br />

and from your mind, and you’re aware of it<br />

at this moment. But you’re only aware of it<br />

for very short periods.<br />

Normally you can only hold on to this<br />

awareness for a few moments.<br />

LONG-TERM memory is information that’s<br />

been previously stored, and you retrieve it<br />

from where it is stored and use it.<br />

Short-term memory seems to contain 5-9<br />

slots.<br />

Short-term memory can only hold information<br />

within this number of slots for a few<br />

seconds before forgetting the information.<br />

Increasing the amount of information starts<br />

to displace information from the slots.<br />

For example, if I were to ask you to close<br />
