Corrected entry: After the battle with Gozer and the Stay-Puft Marshmallow man, if you pay close attention, you can see that the marshmallow goo covering Ray varies in amount, especially after he apologises for the barbecued dog hair comment.

Correction: Just before the barbequed dog hair comment, watch Ray in the lower right section of the screen. He is clearly seen to be wiping marshmallow off of his face, which accounts for the change in amount.

Corrected entry: When Dana returns from dog form she has no foam in her hair. When she emerges from the building at the bottom with Bill Murray she does.

Correction: She had to walk down the stairs through the entire building with a group of people covered in marshmallow. It wouldn't be hard to get some on her on the way down.

Correction: Both shots take place during different time frames: When she becomes human she has no foam, and much later on she walks down the building with foam on her. There's plenty of time for her to get covered in foam for whatever the reasons.

Correction: It is an ellipsis, many minutes in between have gone by. It is not a mistake that takes place in a matter of seconds. She could have hugged any ghostbusters and get covered in foam, for example.

Corrected entry: At the beginning of Ghostbusters, Peter Venkman says that he studies the effects of negative reinforcement on ESP ability, when, in fact, he actually studies the effects of positive punishment on ESP ability. This can be seen in the fact that he adds an aversive stimulus to the subject when the subject "gets it wrong" in order to decrease that behavior, which is positive punishment. If he was studying negative reinforcement, he would have to make the shock occur at all times unless the subject guessed the right card, at which point, the shock would be removed. Of course, Peter's methods were shown to be less than sound.

Correction: The "negative reinforcement" occurs with the female subject. She sees that the punishment for getting a wrong answer is electric shock. When she gets the right answer (or so Venkman tells her) she escapes that aversive stimulus. *That* is negative reinforcement. The experiment is bunk anyway, because Venkman is lying to them both.

You could just as easily say that she's receiving positive reinforcement because he keeps complimenting her. The only thing that's for sure here is that his experimental design and conduct has a faulty member is poor.

Correction: The shock isn't the only stimulus. He's is also either being overtly obvious that he's helping the woman OR could be that the stimulus is the woman getting all the right answers.

Or that Venkman is a hack and doesn't know the difference between negative reinforcement and positive punishment.


Corrected entry: When Dana tells Peter of the refrigerator incident, Peter opens the door to investigate. On the top shelf is a can of Coke with the label "Coke" clearly displayed. Just a moment later, he double checks the fridge, where the can now reads "coca-cola." Somebody turned the can between shots.

Correction: There are two cans, it's just that in some shots we see them one at a time.

Corrected entry: When Ray purchases the car for the business, Peter comes up and asks "how much?" In that scene, Peter is wearing a green and black checkered shirt and then he waks inside and asks if there are any messages. When he walks inside, he now has a completely different shirt on.

Correction: The scene when Ray pulls up with the car and when Peter walks inside the building are different days. you can hear Dana quite clearly say that the incident happened 2 days ago. So they might have bought the car on the same day as her problem or the day after.

Corrected entry: When Dana is tested if she's telling the truth, right after she says "Who would make up story like that?", we can see her saying "yeah I know" silently, as if she had messed up that line. (00:23:00)

Correction: She says "make up a story like that". She didn't mess up the line. Why she made the facial expression is therefore moot.

Revealing mistake: There's a scene where Dana's building is falling apart and stones and stuff are falling to the street below. One of the huge boulders bounces off a wooden police barricade in the bottom left hand corner of the screen, and then off a person. (01:29:14)
