Posted on your blog,Trish,but Ive read and would reccomend two of Bens books;
"The art and science of clicker training for horses" is a great instructional one and " The horseman within" is great too.

got it, thank you so much! and i've ordered that first book

i'm still WAY behind on reading the 6+ pages here

but i wanted to post what i consider a very good definition of the title of this thread:
A poisoned cue is one that sometimes has a negative consequence instead of a positive one. A cue becomes poisoned when you cue a behaviour and use a correction such as negative reinforcement or punishment for the incorrect behaviour and positive reinforcement for the correct behaviour.
For a behaviour trained entirely with positive reinforcement, if one now clicks for correct behaviour following a discriminator ( a cue, command, or signal) but also gives an aversive correction (negative reinforcement, punishment) for incorrect behaviour following that same stimulus, the stimulus immediately loses its value as a positive reinforcer. It is, at best, ambiguous in terms of reinforcement. It is not a click. It no longer automatically triggers the positive emotions associated with conditioned positive reinforcers. It can no longer be predictably used inside a chain to reinforce previous behaviour.
which i found in the 'CT terminology' section here

- really clarified things for me. AND made me realize that i have indeed done some 'poisoned cues' inadvertantly.
Ben Hart makes a thought provoking comment in one of his books about that which is to ask yourself whether you/your horse have ANY unresolved issues.
my initial reaction to this was "me? no!" but days of horsey inactivity (due to horrid weather and long work hours) have caused me to spend lots of time reflecting on this.......and i realize that i really
cannot say "no" 100%

. not really anything *major* imho, but it's there nonetheless. so i'm diving in, trying some true/pure CT

. not sure where i go from just target training? am going to post my own thread addressing this, along with a few other question so don't bother answering me here
