Thanks a l❤t! I'm passionate about becoming a university lecturer or taking an academic job, so I have two questions: 1. Someone with a master's in clinical psychology and a PhD in Neuropsychology is capable of teaching in both fields? 2. Does A professor need also to practice programs?! Like going to hospitals and...?
You saud "I don't have the time or inclination". Try my patent pending recemic l-time, d-inclination product!
Why did it lose audio ?
Honestly, I'm not sure... back when I was making these videos, I was more-or-less teaching myself how to do recordings with PowerPoint and TH-cam.

Excellent Lecture series! Thank you for this.
You're welcome. I am happy that people are still getting some benefit from my old lectures!
Professor, do you supervise PhD students? I am looking to do PhD
@@Ali-lm7uw I’m flattered by the question, but unfortunately the answer is “no”. I’m no longer a professor of psychology. These days, I am in full-time clinical practice.
That's unfortunate professor, usually Psychology professors do not have a good grasp on research and statistics. But I see you are quite passionate and proficient in Research. I will watch all your lectures and prepare for starting my PhD in Psychology. Thank you sir .
Great lecture, you’re fantastic
Slimmers found them useful but became addicted .coming off them was not nice
Thanks for the is quality of this information
You’re welcome. My lectures are getting a bit out of date (I am no longer a professor), but I think that there is still some useful information in them. That said, please be sure to follow-up by reading more recent research.
Theres actually alpt more alkiliods then just those 3 pretty. Crazy to look into.. papervine noscapine narcotine oripavine....pretty sure oripavine is what they use to make subutex.... and some other stong opiate maybe it is the nitazine opiods
👍
Thanks for posting this for everyone to access Keith you da man
You’re welcome!
Wow, this is the most useful educational TH-cam video I have ever seen. Thank you so much for posting this lecture. Such practical information. I really appreciate it.
If drugs were prescribed weekly, rather than monthly, there would be much less abuse and deliberate or accidental OD'S. When people have a large amount of drugs they tend to use more, this has been my experience.
Why they don't prescribe benzodiazpines for amphetamine abuse is beyond me. 🙄
Of all the resources out there, I can't begin to tell you how amazingly helpful this has been! Thank you!!
Thank you for your kind words. I am happy that people are still enjoying my old videos. One of these days, I would like to get back to making more.
Amphetamine use in the US is near 1970 levels. I fear that another amphetamine crackdown is coming…
Thank you. These lectures are very very helpful indeed
You're welcome! I am happy that people are still watching my old psychology lectures!
@keithdonohue4631 Theory never gets old and you explain it very well. Very useful for someone like me doing a distance degree. I literally listen to your lectures all the time on my commute, at home while I'm doing chores etc. And then I listen again 😄It's such a great addition to the self study that I already do. Thank you again
Hello Keith Do you know how one gets formally trained on administering and scoring the RBANS? Thank you Debbie
I am thinking of changing my career and becoming Neuropsychologist, but not sure how much of hard work, consistency and resilience will be required...
In the United States, you typically have to earn a PHD in clinical psychology, and then follow-up with a specialized clinical post doc in neuropsychological testing, in order to be licensed and credentialed as a neuropsychologist. That’s a lot of fairly challenging course work and clinical work.
@@keithdonohue4631 how many years will it take? and Do I need to do Bachelors again for this? Since I did my Bachelors and MBA in Finance...

How can I get access to your other lectures on neuropsychological and other types of testing? Your presentations are great!
Where is lecture 8a?
I think that the numbering of my lectures is a little bit inconsistent, because it is based on a course that I used to teach live. I made a practice of re-recording some of the lectures, if students wanted them, or if I felt they might need a resource for review. Sorry for the confusion.
The Benzedrine inhaler should be brought back.
From philippines thank you. Hoping to pass my board examination this year
I'm a freshman in college who aspires to study neuropsychology in the future. This video honestly has solidified by love and interest for the subject. Although, I have some questions and I'd love to email you to see if you can answer my questions. Hope to hear back from you.
Oxycododone is a Thebaine derivative not morphine
You're right. I think I meant to say that oxycodone was derived from opium (specifically thebaine). Oh well, mistakes were made...
Thank you for this free lectures you've uploaded years back, this would totally help me in my upcoming Licensure Examinations here in my country. 🥺💕💕
You’re welcome! I wish I had the time to update or expand on them, but I am busy with my career as a full-time clinical psychologist. Good luck with your exams and your career!!
@@keithdonohue4631 that's totally fine! Making this free for everyone who wants a refresher with Psychological Testing/Assessment for their review means a lot to me already. 🥺💕
I must say that ,I must be a rarity as a user and abuser of this drug. I have not really had any schizo side effects that you describe. In fact ,I have not had any of those side effects you speak since I started in q1985 ,16 yrs.old .and in those days it was the best I seriously would extend the days if possible to 5/7 day benders less than 3 days was pointless because thatv is when all the halleucinations both auditory and visuals started . After 7 days is when it got kinda scary.but I will say in all honesty I never went out became a thief or any crimes or deviant behavior or obsessions with sexual weirdness ,no I'll do anything for a fix like some girls and mostly gay men do ,never sold my body and never sold everything I owned still had some limits and parametersand scruples and morals were always kept to a standard
i had serious physiological side effects when consuming it in not very much amount. i dont know why. can we shed some light of your experience? have any contact?
When you start talking about adhd and stimulants it goes wrong you show a picture of the worst adhd medicin ritalin and the one and only reasonible effective and good medicin IS AMPHETAMINE! and the more pure dextro amphetamine whitout prolonged disolving the better for treating the adhd symptoms children or adults it does not matter and its finally been studiet and proven world wide a couple of years ago
In addition, your graph isn't delineating marijuana sale vs simple use. That's a distinction with a very big difference in the mind of law enforcement.
I'll suggest that a reason for the discrepancy in white vs black arrests for marijuana has to do with income levels and where they live. It would make sense that more affluent people would smoke in their homes or other privately owned areas, whereas poorer urban blacks would be doing it outside, more or less in public. Also minority populations tend to live in urban areas, where there are more police or more exposure to police than rural or more affluent whites. I could be wrong, but we should look more into where the arrests happen. Another thing, whites are probably more likely to sell in private homes, dorm rooms, less suspicious locales, vs urban drug sales in open air markets.
Did you find any information on the legal production and global trade in opium in the present day? When I tried I didn't find much apart from that a substantial amount of what they refer to as "Opium Gum" from Afghanistan and the middle east is brought into Turkey and stored in warehouses before being purchased by Pharmaceutical companies and governments of Countries with national health services and being converted into morphine and other pain killer drugs in production facilities, It was also quite surprising that many countries that you wouldn't expect too like England for instance are growing limited amounts of poppies on specially licensed farms at home in an effort to be less reliant on imported Opium Gum, the amount and price of which is subject to fluctuations, Still though there's hardly any easily accessed info on the legal global trade...
That relief carving of the person using the pipe was interesting, there seemed to be a tiny man with a rod in his hand riding the pipe like a person might control a horse or beast of burdon ,, possibly alluding to the addictive nature of opium??
One correction, amphetamine's stimulant properties weren't really understood until the interwar years. Coca products were used primarily in WWI, along with caffeine and strychnine. Another correction: Mother's little helper referred to Meprobamate, which was around at the time the Rolling Stones made their song. It came in 'little yellow pills' however modern culture usually assumes these pills to be 5mg diazepam tablets, which weren't on the market at that point. Stimulants were widely prescribed up until the 60s for housewives, after which sedatives were more often prescribed as a first line treatment for 'nerves'. Speaking of stuff from the wars, I may be able to get you some photos of stuff used in both wars, related to this video and some of your other videos. Friend of a friend owns a museum which has a collection of WWI and WWII medic's stuff. Pills and boxes mainly.
Extremely helpful and easy to understand. Thank you for the great explanation, sir!
Can anyone explain how a k correction is performed?
K correction is done as an automatic calculation in the computer scored version of the MMPI-2. I don’t remember exactly how the calculation is done. It isn’t done on the MMPI-2-RF or -3.
www.upress.umn.edu/test-division/mmpi-2/mmpi-2-faqs
The k correction was developed by McKinley, Hathaway, & Meehan in 1948 and involved adding some fraction of a test-taker’s k score to some of the other scores. The idea was that test takers with elevated k scores were answering the test in a defensive way , and thus their scores on some of the other scales should really be higher ( if you could account or correct for the defensiveness). Over the years, research and clinical usage suggested that this was a interesting idea that didn’t actually improve test performance. So it wasn’t included in modern versions of the test.
Thank you for thorough explanation. This was really helpful, looking forward for more test's interpretation.
You're very welcome. I'm afraid that I don't have any more videos planned, as I've switched from being a full-time professor to being a full-time therapist, and that doesn't leave me with much time for making new TH-cam content. That said, I would like to do something... maybe a new video on the MMPI-3 or the MCMI-IV, in the coming months.
22:31 this has always been the strange part when it comes to suppression. Very few people explain the effect of the suppressor on the DV. For instance, we are left here with anxiety having a negative beta when it comes to anhedonia. Someone looking at the betas might conclude that the more anxiety you have the less likely you will experience anhedonia. So is it misleading to leave it in a path model like this? How would you interpret the effect that anxiety has on the DV? In this case, I'd probably turn them into a composite variable (depression and anxiety), but assuming you didn't, can you give me your take on the best interpretation here, regarding anxieties effect on anhedonia?
20:31 in this scenario is "anxiety" the suppressor variable, or are you saying "depression" is the suppressor?
It's been a while since I made this lecture, but if I remember correctly, I was trying to set-up anxiety as a potential suppressor for the relationship between depression and anhedonia. To be honest, if the variables are all measured at the same time (e.g., you gave out questionnaires for anxiety, depression, and anhedonia at the same time), then which one is the predictor, which one is the outcome, and which one is the suppressor is just a matter of how you chose to set up your analyses.
@@keithdonohue4631 Ok, yes, this makes sense, I just wanted to double check! Thanks for the great video!
So Sad Govt and WHO scam and plan to ban this gift of nature only for money and people dying from pain and overdose of heroin but if opium legal no one will go to synthetic drug.
Of course you have to have people commenting on every video mentioning amphetamines that they take adderall, evekeo, vyvamse, dexedrine, etc for adhd and how it makes them feel euphoric, motivated , and happy 🤣🤣🤣 How do you know someone is prescribed adderall? One, they don't shut up, two they'll let you know as if they have the shiny toy you can't have. Just so y'all know, I take Ritalin! It doesn't "bring me out of the corner" but I can focus!
May I ask why scattered data in scaled scores is difficult to interpret?
Hmm... It's been a while since I taught my assessment class or even used a WAIS, but let's see if I can answer your very good question. We can think of the WAIS (and many tests of cognitive abilities) like a set of bigger scores, made up of smaller scores. The FSIQ and GAI scores are made up of composite index scores (like VCI, PRI, etc.). And the composite index scores are made up of subtest scores. All these scores are trying to tell you something about the test-takers abilities. The FSIQ score is trying to tell you their overall cognitive abilities, the VCI score is trying to tell you their verbal comprehension ability, the vocabulary subtest score is trying to tell you their ability to use vocabulary... If all the components that make up a particular score are very consistent, then we can usually feel confident that the score is giving us good information about that test-taker's actual or "real" abilities. If all the composite index scores that make up the FSIQ are really high, then we might feel pretty confident in thinking that the test-takers overall cognitive ability is also really high. If some of the composite index scores are high, but others are low, the overall FSIQ score might still be fairly high, but we might now feel less confident that it is giving us good information about the test-takers overall cognitive ability (what the FSIQ score is supposed to be telling us) -- maybe that person really has varied cognitive abilities, such that they are stronger in some areas and weaker in others....?
In a sense, this is all just classical test theory. Any observed test score (FSIQ, VCI, vocabulary subtest) is made of of the test-takers "true" score (a perfectly accurate measure of their ability in that area) and error (all the things that cloud or distort our understanding of that true score). Error is operationalized as variability in measurement. If the test-takers scores on a given composite area are highly variable, that is a lot of error in our measurement of whatever the index for that composite area is supposed to be measuring. We should feel less confident that we know what the test-taker's score should "really" be.
Eugenists at work.
There certainly is an overlap between some areas of psychological testing, particularly intellectual ability testing, and eugenics movements in America (and elsewhere), but I’m not sure I see the overlap between neuropsychological testing (at least as I have presented it) and eugenics. Is there a specific concern that you have?
Oxycodone actually comes from the baine not morphine.
I think you're right. I must have made a mistake in the video. Thanks for catching it.
Where is lecture 8a
I think that there isn't a lecture 8a. It's been quite a few years since I last taught this course (I'm in full-time practice, now), but I remember that the numbering got a little bit off, because I was mixing online work with in-class work. I'm pretty sure that this lecture is just supposed to follow the one on introduction to ability testing (even though the numbering doesn't make complete sense!).
@@keithdonohue4631 Thank you for helping out. I had a quiz tomorrow and i needed an integrative report. I thought that the 8a lecture might have anything on that. You saved a lot of my time today. Thank you again.
Sir, about the uses of testing - maybe I am wrong, but I think testing (follow up) can happen post the assessment as well to check if the treatment is/was successful, and then it verifies the initial assessment/result.
Wow. It's always fun for me when someone finds one of my old lectures on testing, drugs, statistics, etc. Thanks for watching and commenting. You are right that testing can be used to evaluate the effect of a treatment. Ideally, you can do pre-treatment testing and post-treatment testing for two groups of subjects, one of which gets the treatment and the other of which does not (the control group). Then, you could use graphical or statistical analyses to compare the changes (in test scores) across the two groups, to help you decide how effective the treatment was.
You are also right that you can repeat a test, with just one subject, to try to evaluate the validity of the first test. For instance, you might administer multiple versions of the same test (e.g., alternative versions of the R-BANS), across different testing days, to measure a subjects neurocognitive functioning. If you can assume that whatever construct you are measuring (e.g., working memory) is fairly stable over the time-frame that you are testing in (e.g., if working memory *shouldn't* change a lot), and if you can assume that there are no independent effects of repeated testing (e.g., if doing memory testings again and again *shouldn't* result in improving scores because of practice or changes in effort), then the results of these repeated tests help you to estimate the persons *true* score for that test. For instance, you might take an average, across multiple tests, and use it as the estimate of what the person's working memory score *really* is. The mean of the test scores that you have is a statistic that is estimating a parameter (i.e., the mean of all the test scores you could have, if you repeated the test with the same person and infinite number of times) that *should* reflect the reality of the construct (i.e., what the person's working memory *really* is). Of course, you can't ever do this (you can never know any parameters, you can only ever estimate them with statistics like means, medians, etc.). The point here is that repeatedly testing isn't so much about verifying the first test results, as it is about estimating what those results -- or any results -- should *really* be. And if it's not obvious, I have used a bunch of "*"s to emphasize that all of this rests on assumptions about the construct that you are trying to measure (e.g., does it even exist as a unitary thing, does the test even measure it at all, is it stable over time, can you really test repeatedly without biasing your estimate...?). The more you think about it, the more confusing it can get!
I try to talk about estimating *true* scores in my video on Classical Test Theory and in my video on the WAIS (th-cam.com/video/hUGFR8odet4/w-d-xo.html)
@@keithdonohue4631 Thanks much for your response, Sir. Psychological testing was a difficult topic until I saw your videos - these are extremely insightful and have made concepts super easy. Best regards. :)
10:11, it'd probably be ideal for progesterone oriented premenstrual lethargy... And mood elevation for the more uninitiated to amphetamines. It also can help with constipation, just saying. Other than that, I'm not sure how helpful it is for menstrual related discomforts 😉
Thank you Dr.Keith! Your presentation did what you intended to do very well; It explained the concepts in simple terms without a ton of maths. I appreciate this so much as a medical student.
You’re welcome. It’s been quite a few years since I last made any videos. I have been working full-time as a practicing psychologist, after leaving my previous position as a college professor. I’m glad that people are still finding some interest in my old lectures.

Nice racist comment about the white guy.
Hmmm… it’s been a while since I recorded that lecture, so I don’t remember the part you are referring to. Could you tell me the time in the video when it occurs? Thanks.
@@keithdonohue4631 Around 41 minutes; talking about executive function and 'oh yuck! A white guy'. It's just so woke. Most executives in the US are White guys... so, it is representative. As a fellow educator, I say let's get these comments based on skin color out of our lectures unless they are really pertinent to the discussion.
@@tootsietoyrestoration I found the part that you are referring to, and I don't think that I agree with your characterization of what I said. Obviously, I didn't say 'oh yuck! A white guy.', so your quote (?) doesn't really make sense. Rather, I made a comment about the process that I went through, when making my PowerPoint slide for this introduction to that unit. I was disappointed that most of the free image searches that I made for the keyword "executive" returned images of older, White males, because I didn't think that this gave fair representation to the range of people who serve as executive in businesses. Maybe things are different now, but back when I made this lecture, that's how they seemed to me, and that's how I felt. I'm not an educator any more, when I was, I tried to be mindful about not reinforcing cultural representations (e.g., executives are only or overwhelmingly white males) that tend to disadvantage females and minorities. Even if it's the case that most executives are white males, I think it's still important to offer (or at least acknowledge the possibility of) other possibilities. And it's easy to come up with other scenarios where this desire for representation might work the other way. If I was writing a lecture on empathy, and I searched for free images to depict this concept, then it might very well be the case that most would be of women. I would probably try to find an image or two that showed a male behaving in a compassionate way, so as to not reinforce a cultural representation (i.e., that empathic people are only or overwhelmingly female) that tends to disadvantage males. If all this counts as 'just so woke', then I'll accept that label. You and I probably disagree about some priorities in education, and I suppose that's okay. In any case, thanks for watching my video.
@@keithdonohue4631 Well, the white oppressor theme is alive and well in your answer. White executives do not 'disadvantage' women and blacks - that is simply unsupported wokeness. Here is the ONLY male (other than your photo) in the whole video and you feel a need to apologize and explain, but the four or five girls and women in the video needed no explanation or apology. You made a good video, but stepped on my toes with that one remark... I then felt an uncharacteristic strong urge to label it racist and you took the bait. Your answer was considered and kind - much appreciated. Keep up the good work.
