We trained our dog Gemini using positive reinforcement techniques, “clicker training.” She can sit, give handshakes and high fives, roll over, and we never used negative reinforcement to teach her.
That’s all true, but what do I mean by negative reinforcement? A lot of us assume that it has something to do with punishment, whereas positive reinforcement involves rewarding good behavior, but this assumption isn’t strictly true. To reinforce a behavior is to make that behavior more likely. Giving Gemini a treat when she sits after I make a certain gesture positively reinforces the association between my gesture and her sitting, because it makes that behavior more likely next time I make the gesture. I’m introducing something Gemini wants to strengthen a particular connection between my gesture and her response. On the other hand, when I strengthen a connection by removing something she doesn’t want, I’m negatively reinforcing the behavior.
Punishment involves introducing something unpleasant to make a particular behavior less likely. Sternly telling Gemini that she’s not allowed to eat the cat food is my attempt to punish her, introducing something unpleasant (disappointed dad voice) to make a behavior less likely (eating her sisters’ food). This hasn’t worked yet – maybe I’m not doing the voice right – but my point is that punishment isn’t negative reinforcement. Reinforcement is about making a behavior more likely; punishment is about making a behavior less likely.
This is a nice example of how technical terminology can be subtly misleading when we’re not careful. Read more »


Today marks eight years since I had my last drink. Or maybe yesterday marks that anniversary; I’m not sure. It was that kind of last drink. The kind of last drink that ends with the memory of concrete coming up to meet your head like a pillow, of red and blue lights reflected off the early morning pavement on the bridge near your house, the only sound cricket buzz in the dewy August hours before dawn. The kind of last drink that isn’t necessarily so different from the drink before it, but made only truly exemplary by the fact that there was never a drink after it (at least so far, God willing). My sobriety – as a choice, an identity, a life-raft – is something that those closest to me are aware of, and certainly any reader of my essays will note references to having quit drinking, especially if they’re similarly afflicted and are able to discern the liquor-soaked bread-crumbs that I sprinkle throughout my prose. But I’ve consciously avoided personalizing sobriety too much, out of fear of being a recovery writer, or of having to speak on behalf of a shockingly misunderstood group of people (there is cowardice in that position). Mostly, however, my relative silence is because we tribe of reformed dipsomaniacs are a superstitious lot, and if anything, that’s what keeps me from emphatically declaring my sobriety as such.

On a small paper bag maybe from a bookstore, one side Romeo’s soliloquy, “But soft! What light from yonder window breaks?” On the other side, these words: “Dorothy lived in the midst of the great Kansas prairies, with Uncle Henry, who was a farmer, and Aunt Em, who was the farmer’s wife. Their house was small, for the lumber to build it had to be carried by wagon many miles. There were four walls, a floor and a roof, which made one room; and this room contained a rusty looking cook stove, a cupboard for the dishes, a table, three of four chairs, and the beds. Uncle Henry and Aunt Em had a big bed in one corner, and Dorothy a little bed in another corner. There was no garret at all, and no cellar–except a small hole dug in the ground, called a cyclone cellar, where the family could go in case one of those great whirlwinds arose, mighty enough to crush any building in its path. It was reached by a trap-door in the middle of the floor, from which a ladder
