Learned Helplessness - an idiot's guide!

There have been so many references lately to Dressage horses displaying signs of learned helplessness that I decided to blog about what learned helplessness is (and is not!)

Any internet search on this topic will usually refer you to the work of Seligman and his colleagues.  They conducted several experiments, mostly on dogs . To understand the experiments you need a basic understanding of learning theory. At its very simplest this states that animals (and indeed humans) tend to repeat behaviours which lead to positive outcomes and/ or the avoidance of negative outcomes. For example, if a bell was rung followed quickly by an electric shock if you didn’t perform a particular action such as pressing a lever, you would very quickly learn to press that lever! This principle is an integral part of training the Dressage horse: a light leg aid signals the horse to go forwards – if it doesn’t go forward then it receives a tap with the whip. Horses quickly learn to avoid the whip by moving off the leg.

In Seligman’s experiments they set up various situations where the stimulus (signal) was applied but the animals were not offered a way of avoiding the negative outcome. So the bell would be followed by an electric shock regardless of any action (more here). Animals (and humans) subjected to these unavoidable negative outcomes learn that they are helpless.  Even if the situation changes, and there arises an opportunity to avoid the negative outcome, many of these animals don’t even try as they have come to believe that any action is futile. In humans this is sometimes seen in victims of repeated abuse and also in some who are clinically depressed. Animals and people suffering from learned helplessness are usually very withdrawn and non-responsive: they feel powerless to change their situations.

Let’s go back to the Dressage horse and look at jaw flexion. The usual sequence is: rider places light pressure on the jaw via the bit – horse flexes jaw – rider eases rein pressure. If the horse doesn’t yield then the rider may increase the pressure. So the horse is offered the option of avoiding the stronger pressure by relaxing its jaw. Result = happy horse, light in the rein.

But what if the horse is not offered a way of avoiding the increasing rein pressure? So the pressure is continually increased and applied even when the horse is in maximum flexion?  Is this in line with learning theory? No, of course it isn’t.  But is a horse ridden like this in learned helplessness?  Probably not. Because when it is offered the option of avoiding the pressure it does so: otherwise horses warmed up in hyperflexion would not ‘come up’ when presented in the test.


Just a bit more...

There have been suggestions that there are grades of learned helplessness, or that it may be context specific. An example could be a riding school horse that is dull to the aids, but a different ride altogether if taken out of the school environment.  Another suggestion is that horses can cope with learned helplessness in a certain situation if they ‘know’ that this is not permanent.  So a horse that may feel ‘helpless’ while ridden may be able to cope if the rest of its daily routine is stable and allows self-expression. At the 2011 Global Dressage Forum, Richard Davison light- heartedeadly likened this to girls at the supermarket checkout who look thoroughly bored but can cope because they know that at the end of the shift they can go out clubbing! These are nice ideas, but the whole point about learned helplessness is that it becomes overwhelming and the feeling of helplessness tends to be extrapolated to all situations. Horses in true learned helplessness would probably not be trainable, or even rideable. They would be withdrawn, unresponsive and unthrifty. They would certainly not go out and perform expressive tests at Grand Prix level!
I hope this post has clarified that whatever your opinions about hyperflexion and its physical effects on the horse’s way of going (I have mine, but will keep them to myself!), successful dressage horses trained by this method are not in learned helplessness.

  1. Thanks for the introduction to the concept of learned behaviour - I shall have to think about that with both horse and dog. Nice blog, how did you get your test block so broad? Mine seems narrower by comparision but I haven't spotted where to adjust it? HWD

    1. That should have been text block by the way.

  2. Thanks for the feedback, HWD, it's very much work in progress.

    I think the text block is the default setting, but you can change it in template - adjust widths. Hope this helps!
