Maybe because it's a city in Africa now?
Freud is so widely disliked (particularly by women) because he was so widely correct about human nature and unafraid to speak his mind. The sad truth is that we currently live in a world where whistle-blowers and people who speak the truth are all too often ridiculed and even reviled.
I wonder, what is the demo tool you use, where you are able so elegantly to edit while doing the demo? :)
absolutely fantastic overview of LMMs! Good balance of demonstrating many aspects of the model, tools, and of course, interpretation
Shocking to see now Israelis using the jewish holocaust to justify their genocide of Palestinians and the Palestinian holocaust.
Apparently, Chinese tourists are also being afflicted
Great lecture
Sir, this is a wonderful video, thank you
This individual was addicted to chloral hydrate (HIGHLY ADDICTIVE) and morphine (ditto), both of which she was given like candy for her asinine behavior. God knows what else, Freud himself took enough cocaine to kill a horse. Ether was a big problem then too (TS Eliot's wife Vivienne was addict). When Hunter S. Thompson is cataloguing the drugs in FEAR AND LOATHING IN LAS VEGAS it's not the pills or LSD or grass that scares him, it's the ether he's most concerned about. May I point out that before Ecstasy became a SCHEDULE 1 drug with the Drug Enforcement Agency in the U.S. it was used by marriage therapists in California whole doled it out to patients under the name of EMPATHY. Thank you clinicians! Appreciate that one! Now virtually half the kids in the US are drugged for "disorders." This mania began with ANNA O and others under the name of "science."
Paris is no longer a European city, that might be part of the problem.
Do her symptoms not sound like some kind of neuropathological condition … started at pns and eventually went to cns…
I'm not Japanese and I've had Paris syndrome, Paris is awful
It would be like visiting North Korea and it turns out to be a thriving utopia.
Oh I wonder what it could be in France causing this condition, an Elephant in the room I suspect.
Very clear. Thank you.
6:05 But previously you said 5-6 groups is ideal for a variable used as random effect. But if you also say participants are used as random effect, isn't usually 100s of participants in a study? Doesn't that mean hundreds of groups in the random effect variable (participant ID)?
They should have left him alone, he wasn't retarded, autistic or psychotic, if anything 'Victor' could have taught them something.
This happened to me im japanese. I later died.
RIP
VaatiVidya, is that you? :)
Its because its no longer French. It was exquisite in the 70s and early 80s. Not anymore though. The life force has been sucked out of it. Irish visitor.
My son had what seemed like an Oedipus complex but it wasen't because at 5 he wanted to sleep with me but because the monsters came out of his closet at night and scared him. He knew when my husband was out of town he could sleep safe in my bed but when my husband came back from a business trip he couldn't as my husband and I after being away from each other for many days naturally wanted to have a great deal of intimacy. Thus when my husband came home from a trip he would push the door close and say "Leave, I'm sleeping with Mommy". Rather than this being sexual he explained the monsters did not follow him to my room. His sister who was 4 years older than agreed to allow him to sleep with her and he felt safe there until when he was about 8 he outgrew all fear of monsters.
I can’t believe i never heard of this!
3:52 😂😂😂
I wonder if there's a name for when weebs visit japan (when they're not in tokyo or other major area)
Thanks for the excellent explanation. May I ask why you used the "SUM" for an ordinal data scale scored at the 7-point Likert scale instead of the average/ mean? and also you used "average" for the other ordinal scale variables? if the sum method is better, what would be the procedure if I have 3 main variables with different number of dimensions, e.g. IV: measured by 6 dimensions*3 items each, DV: 4 dimensions*3 items, and MD: 6 dimensions*1 item.
Very useful. Thank you.
Reminds me a bit about the old David Lean movie Summertime, about a middle aged American woman, unmarried and played by Katherine Hepburn, who visits Venice on vacation and has a bit of culture shock when the Venice of her imagination is challenged by the actual Venice of its residents, who are more or less like people anywhere in most ways, just different culturally, and she has a bit of a hard time adjusting. But eventually she does, of course, and loves it. It's actually the basic plot of way too many "fish out of water" movies and TV series, from Emily in Paris to Under the Tuscan Sun, and a staple of light rom-coms one might watch when you don't want to watch anything too heavy. I just saw one about a young but not too young American woman who travels to Vietnam after a breakup and has a bit of a culture shock. Of course, as ALWAYS happens in these things, she meets a local and falls in love, but not before various complications ensue. Anyway, everyone has culture shock to one extent or another when venturing too far from familiar surroundings for the first time, whether it's the next block over when you'd a kid to another part of the country when you're a bit older to on the other side of the world. People and cultures are different in certain ways and it's always a bit of an adjustment. My view is that if you didn't experience culture shock then you didn't really experience anything real and were on a canned vacation.
When you use it to estimate a mediation model, should you exclude some of the covariates from one of the two equations?
If there is a strong rationale to include covariates, they should probably not be excluded.
@@PsychEDD using lavaan though i get an error that says that the model is not identified, Do you have some suggestions?
Hard to say without looking at the code/data and I don't frequently use mediation models (more of a moderator type of person) - i'd recommend just having a look through the syntax on the lavaan tutorial site to see if there is perhaps something you've missed: lavaan.ugent.be/tutorial/sem.html
Excellent presentation, thank you
Neurosyphilis symptoms are absolutely terrifying. It sounds like these studies did not contribute to researching this disease since they continued administering placebo treatment to participants for another 30 YEARS after a treatment that was effective in treating it was found. So sad for the participants and their families.
The syphilis bacteria literally eats away at the brain - terrifying indeed!
Well, the dates and pics don't add up. No one was taking pictures in the 1700's.
I took the photos myself - trust me, it was Victor.
You must always greet a Parisian with Bonjour ! Once you try to speak French the ice is broken and they are very nice. Just be courteous and polite that is what they expect and they are the same in return. It is a very beautiful country with beautiful people from my experience…
Yes, exactly. Show them proper respect and don't act like you're entitled to anything as an American or whatever, and you should be fine. Sure, you'll come across rude people, but that happens almost everywhere.
This is one of, if not the best video on the topic here on youtube. Very well done.
As a British guy who was laying over in Paris for one night, as I arrived at the Charles de guale airport, I was immediately harassed by a guy asking me where I'm going and if I want to get in an Uber with him. After he finally went away and I found a taxi to take me to my overnight hotel, he tried to charge me 60 euro for a 10 minute ride. I just handed him 20 and told him that's all I'll give him since 60 is ridiculous. After I got to the hotel I asked the receptionist in broken French that I have a reservation and she was snarking at me like I was a cockroach, she finally gave me my key and sent me to the room. Then the lift was broken and my room was on the 9th floor so I wasn't taking the stairs. So I went back to the reception to ask about the lift and apparently you need to use a key card (that she never gave me) to operate the lift. >.> The breakfast in the hotel was nice though. Honestly I kinda got depressed after 1 night and would never go there again... and I'm a westerner. 😂 Must be hellish if you are coming from somewhere as sophisticated as Japan.
Now I know how the genocide of the Jewish people happened. But, then again, doesn’t Jesus say not to resist evil and that evil must happen because it’s part of a godly plan? To the hell with this religious nonsense!
The majority of people would do this. And, yet, we’re still under the spell of the idea of ‘democracy’, being at the mercy of the mobs. What am I missing here?
I remember studying this in A-level psychology
This sounds somewhat like Naive Realism.
how can this experiment apply to and explain the concepts of pliance and tracking?
I was kicked out of 2 police academies for being disobedient. Dude is a fucking tit. Whole thing is rigged.
How many people wanted to continue with the experiment just for the $4.50?
do i even have to write this down in my exam paper 😭my god so twisted
It's illegal now and no ethics committee anywhere in the world will give permission but I'd like to see how it would go outside the US.
When shady dude in the street corner sells you something, take it, and you will see the Paris of your dreams.
Surprisedly the Paris France that the Japanese and other Asian countries fantasize so much fits more the description of Monaco 🇲🇨 It matches all the luxurious high expectations that they assume with Paris France. 🤔 Imagine if the Japanese man that began the whole Paris syndrome decided to save up all his life savings and took a trip to Monaco 🇲🇨 to wash down the disappointment of Paris France, only to realize “Oh my freaking gosh!? It was France’s neighbor all along!” 🤯😵😭 Sometimes the country of your traveling dreams is where you least expect.
Maybe if they were gambling enthusiasts😂
this is the best video i have ever came across that simplified the link between longitudinal data and mixed effect models. It is really helpful and thanks a lot for this video
Very interesting but skip the music!
