what is signal detection theory? - ok science

This video covers the basics of Signal Detection Theory, including hits, misses, correct rejections, and false alarms, sensitivity, and receiver operating characteristic curves. We also look at how Signal Detection Theory is used in everyday life to answer questions that other ways of looking at data don't!

The irony of discussing noise in signal theory with that background music.

Really good video but skip the music next time or maybe lower it? :)

Excellent video and example using Waldorf and noise! I am a perception scientist, and sometimes I get confused about the signal detection theory too. It's a great video to get me back to basics (and to rethink from another perspective) when I am getting confused about my data again!

I agree - your voice faded in and out but the music was always louder than the voice. Distracting, frustrating

[amnanajib]

could you just please remove the sound on the background :) ?

this video helped me understand this sososo much better than before thank you!!!!

I loved this video.
Here I was, watching Richard and Mortimer, when Richard suddenly shouted out his deep and insightful catch phrase 'wubba lubba dub dub'. Only true intellectuals (such as myself) would be able to grasp the theoretical undertones of such as statement, and it brought to mind my college days of statistical analysis and engineering. So here I am, reveling in my superior intellect. and yes I have a rick and morty tattoo, and no you can't see it.

My professor put this in our material to go over and I really wish he hadn't. The concepts were explained really well but the music was too loud. The water sound actually hurt my ears but I couldn't turn it down because I couldn't hear the speech otherwise. This video definitely could have benefitted from better editing.

Many thanks for this, I'm planning to play a section in class tomorrow for my students :)

Great work on this. The structure of your presentation created a nice flow of definitions, conceptual explanations, and applied knowledge. Also, the simple language you used really assisted in grasping signal detection theory. Keep it up!

Great video, nice exaples, well exlplained. but the background audio is irritating and has high volume. please focus on sound quality and music to match your presentation and explanation.

not being a hater or anything, if i were to identify the 'noise' in this video, i will tell you its the background music... love the content though

[screamingperson]

Hey thanks a lot for this man, you legit explained it 10x better than khan academy did

[andreawang]

Great explaination! Thank you so much!

[batoolhayat]

this background sound wasn't annoying until I read the comments about it then it became annoying ugh we humans work weird.

[avapayne]

how did i end up here, i’m litterally 13. Great presentation tho 👍 explained it rlly good

[ddss]

Hey, I know this video is old but can you please provide the sources for the stats about hits/false alarm proportions in sequential and simultaneous lineups that you showed at 13:11?

[meryemgumus]

was very informative! thank you now i understand this topic better. but this background music is a disaster!!

[sitorkeens]

Why did you have to add music?! Its so distracting!!!
