The Address I Heard Wrong: A PS200 Unit 1 Discussion Post on an Everyday Cognitive Slip
PS200 · Unit 1 Discussion Board Post
Posted by [Student Name]
The writer, the call and the classmates are composite; the sources cited are real.
Initial Post
I work nights as a 911 call-taker in Sacramento County, and the slip I want to describe happened on my third call of a shift last month. A woman reported that her father had collapsed. I asked for the address, she gave it quickly, and I typed Fulton Avenue. The mapping screen dropped the pin about four miles from the cell tower that had carried the call, and when I read the address back she said, "No, Folsom." We caught it in under twenty seconds, but I have thought about it since.
I can see three ways cognitive psychology might explain it. The first is perception. Fulton and Folsom share their first sound and their rhythm, and the caller was crying, so the acoustic signal was poor. My brain may have filled in the missing sounds with a street I type more often. Warren (1970) showed that listeners report hearing speech sounds that have been replaced by a cough, so filling gaps is normal.
The second is attention. While she spoke, I was also watching the call timer and the other line flashing, so I may not have been fully listening.
The third is memory. I had to hold the address for a few seconds while I clicked into the location field, and something could have slipped during that short delay.
A two-syllable street name went through perception, attention and memory before it reached the screen, and any of the three could have changed it.
I suspect perception did most of the work, because Fulton is the street I hear most often on the night shift. Goldstein (2019) describes this kind of top-down influence, where expectations shape what we perceive, and that seems to fit.
My question for the class: when you made a similar slip, did you notice it yourself, or did something outside you, like my map, catch it?
Reply to Priya
Priya, driving past your exit mid-phone-call is such a familiar story. Strayer and Johnston (2001) found that drivers in conversation missed more signals even with hands-free phones, which suggests attention rather than your hands was the problem.
Reply to Luis
Luis, forgetting why you walked into the kitchen sounds like a memory slip, but could a change of setting be part of it? I would like to know whether going back to the first room helped you remember.

Reading the PS 200 Unit 1 instructions
PS200's opening board asks you to describe a slip from daily life or work and name the cognitive process you think was responsible. Pick a slip you can describe precisely: what happened, what you were doing at the time and how the error was discovered. Offer more than one possible explanation, since perception, attention and memory often produce similar mistakes, and say which you find most likely and why. A source on cognition, even the course text, helps the post sound like psychology rather than anecdote. End by asking peers how their own lapses came to light. In replies, suggest a process that might explain a classmate's error, ideally with a study that tested it, rather than simply sharing a similar story.
How this PS200 Unit 1 example is built
The call-taker's post opens with the collapse call, the typed street, the misplaced map pin and the twenty seconds it took to correct. Three short paragraphs test perception, attention and memory as explanations, with Warren's coughed-over speech sound supporting the first. A highlighted line traces the street name through all three processes before it reached the screen. The writer favors perception because Fulton is the more familiar street, citing Goldstein on expectation shaping what is heard. A question asks how classmates caught their own slips. Priya's reply links a missed exit to Strayer and Johnston's driving study, and Luis's asks whether returning to the first room restored a forgotten errand.
PS200 Unit 1 rubric: what earns full points
Instructors reading this first board look for a slip described in enough detail to analyze and for at least two possible cognitive explanations. A post that jumps to one answer, or names a process without explaining how it produced the error, earns less. Precise vocabulary such as top-down processing or working memory shows early learning, but only when it is used correctly. A source, cited in APA style, lifts the post above anecdote. The closing question is expected to invite real replies. Replies are assessed on whether they add a process or a piece of evidence to a classmate's account. A courteous tone toward peers matters on this first board too.
PS200 Unit 1 help from the desk
Many posts tell an amusing story and never name a process, which leaves nothing cognitive to discuss. Another frequent issue blames memory for every slip, when attention or perception often failed first. Students sometimes use terms from the textbook loosely, calling any lapse a working memory failure. Posts drawn from work occasionally include details that identify customers or patients; describe the situation without names or addresses. Replies tend to say only that the same thing happened to them. Before posting, write one sentence on what you were doing at the moment of the slip, list two processes that could explain it, and choose a question that requires classmates to think about their own errors.

PS200 Unit 1 questions, answered
What counts as a cognitive slip for PS200?
Forgetting why you entered a room, missing an exit while talking, mishearing a name; any moment where attention, memory or perception fell short.
Should the post name a theory?
A tentative one helps, since later units will test it.
How long are replies?
A few sentences that suggest another process that might explain a classmate's slip.
Where can I find a free PS200 Unit 1 sample paper?
This page holds the complete PS200 Unit 1 post on a composite 911 call-taker mishearing a street name, with three possible explanations and two replies.
Which process does the PS200 Unit 1 sample blame for the misheard street?
Mainly perception: a distressed caller's poor audio let expectation fill in a more familiar street name, though attention and memory are also considered.
