Psych Exam Review provides tutorials and answers to common questions, with explanations of the key concepts in psychology and statistics.
These videos cover content in introductory psychology, introductory statistics, and tips for improving learning, and can help students enrolled in university, AP, or IB programs. I try to explain concepts as if I were tutoring a student; going over key terms and explaining why these ideas matter for deeper conceptual understanding.

I'm planning to make some more statistics videos first, then I'd like to cover more topics in cognitive psychology, social psychology, and neuroscience eventually. Thanks for the suggestion!
@@RobertoLion I didn't plan the timing this way but this is very close to the total lecture time for a one semester course (3 hours/week for ~12 weeks)
@dhruvjha4856 I'm planning to focus on the main concepts in statistics rather than specific software or formatting for now, but thanks for the suggestions!
5:00 The assertion that the divisor n-1 has its reasoning in there only being n-1 independent deviations from the sample mean has never made sense to me because of the fact that the n-th deviation is still included in the numerator. Also, the decomposition of the variance into the estimated variance and the variance of the population mean (the bias in this case) doesn’t give an intuition for Bessel’s Correction either in my view; why should the estimated variance s^2 be the difference between the population variance with one score and the population variance with n scores? Nevertheless, thank you very much for this presentation.
Great questions. The reason we include the nth deviation in the numerator but use n-1 in the denominator is that we need to increase our underestimate. If we didn't include the deviation in the numerator and then used n-1 it would be just like having a sample size 1 smaller and the result would still be an underestimate. As for the example of a sample size of 1 (with 0 variance), this is just to demonstrate the maximum amount of error since it would cause us to estimate the variance to be 0. It's not possible to have a variance below 0, and we also can't have a biased sample variance that's greater than the population variance (because the population includes all scores that could possibly be in the sample), so the maximum amount of error we could have for our estimate would be sigma squared, and this maximum bias will then decrease as n increases. Hope this is clearer, thanks for commenting!
Hi there, I would like to praise you as these videos have helped me throughout my studies in order to gain great results. Thank you once again. Greatly appreciated. Much love.
I've added this link to the video description box, thanks for catching that it wasn't there! psychexamreview.com/language-cognition-practice-questions/
I don't have a video covering this as it's not mentioned in most introductory courses but maybe I can return to it if I make more detailed videos on treatment in the future
As a psychology student I’m still unsure how to study because I have to understand the material or subjects + do have know a lot of detail and facts On one hand there are some ed content creators who say that bloom’s taxonomy is best even for memorising and others go with past papers exam q’s flash cards etc
I generally think that Bloom's taxonomy is a great way of thinking about how cognitive skills develop, initially we need to focus on facts and comprehension, and as we do this we'll gradually start to see connections that will allow us to engage in synthesis, critique, and, perhaps, come up with new creative ideas. This isn't in conflict with study strategies like flash cards and retrieval practice. These can be very helpful when initially building knowledge, though they are not as useful for higher order skills (building an argument, critiquing a position, etc.). Once you have enough background knowledge to engage in these higher-order skills, more of your time should be spent on things like writing essays, analyzing a study's strengths & weaknesses, etc. In theory this sounds quite simple: build knowledge with flashcards and retrieval practice, then move to essays, analysis, etc. But, of course, in practice things are a bit more complicated. Even after we have built broad background knowledge, there will always be new facts to learn, and we'll also find that learned material will fade from memory if it hasn't been drawn upon recently. So these different strategies still need to be practiced repeatedly and simultaneously, even for someone who is very knowledgeable in a particular field. Hope this makes sense!
This is for a general introductory course, so it doesn't cover personality disorders in great detail, but these are briefly described in the disorders unit in the following video (there are separate playlists for each unit available on the channel page): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VnUfEeI6PYU.htmlsi=ft5K5weR8W6bop-f
amazing vid but could you maybe not use the images of potentially naked women, cause if my mum walks in she will never believe me that I was actually studying and that I'm also not gay😶
Contention for #3: The question specifically refers to children. Kohlberg's stages occur not just in childhood, but across the lifespan. Piaget's stages of moral development only occur in childhood. The correct answer should be A.
I think this is a valid contention for the wording of "children", but other aspects of the question indicate Kohlberg as a better answer choice, as Piaget included only 2 stages of moral development (heteronomous and autonomous), and Kohlberg referred to 3 levels of moral reasoning. Thanks for commenting!
@@Gela29 There are some variations for how data can be summarized and presented as well as other types of columns that could be included, so you may see some exceptions to the examples and guidelines I've given here. Feel free to ask if you have any questions about specific aspects of a table.
@@shirakumo_tubame If you find the complete playlist with all intro videos on the channel page, all the videos are in order and so the position in the playlist (at the top of the playlist box) matches the video title number. Hope this helps!
@adityapandey8319 Great question, I didn't fully explain this in detail here as it has to do with probability. Essentially, the lower the first score, the greater the probability the second score will fall above that point, leading to a less extreme average. By taking the average of 2 scores, extreme scores are still possible but half as likely to occur. For a more detailed explanation and examples, you can see some of my other replies to comments here. Hope this helps!
Hi, thanks for the playlist. I have a question. I have ZERO knowledge of psychology and soon I'll start my counselling journey (becoming a counselor). Is this series for me? Aim: strengthen basic knowledge so i am not blank in my classes. & To train my mind to learn/study counselling
@@lonewalker1595 Hi, this playlist covers all areas of introductory psychology so some topics may not be as relevant for you. I don't have any specific counseling playlists but you may want to check out the specific unit playlists on the channel for developmental psychology, stress & health, and clinical psychology to find background information that would be most relevant to a counseling program. Hope this helps!
I love how in almost the first video about psychology i watched, i already knew about the topic trough one piece lol (one piece is a huge factor about why i like psychology so it’s basically coming full circle)
@@B-SharpBenchmarksit was a video with both with argument for nature, being doflamingo and corazon, and an argument for nurture, being the effect both of them respectively had on law.
You're welcome. I don't know which areas are causing your suffering, but I'd generally recommend drawing as much as possible when learning biology. Your drawings don't have to be good or artistic, but attempting them will force you to pay careful attention to details and structures and should also help you to remember more. Let me know if this ends up being helpful!
Hey PsycheExamReview, Thanks for this playlist! I'm a third year medical student and I'm so much intrested in psychology and Neuro... Is it possible to pursue online degree in psychology?
Hi, glad to hear that! While there are some online programs for psychology I don't have any experience with them and don't have any specific recommendations. If you're currently a medical student I would suggest asking about any psychology-related courses at your university that you might be able to add into your program.
I do have a general video on the Rorschach test here if you haven't seen it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xok-Wh1awSc.htmlsi=OUWuD70cEjgxhs75 I probably won't be making a more detailed video on the Rorschach test since I'm not a proponent of the test's use and other assessments seem to have greater validity and reliability. I'm not a clinical or forensic psychologist so my opinion may not really matter, but I tend to side with critics of the test and see it as a rather flawed approach to assessing personality. Thanks for commenting!
But what if we decided to play the game, say, max. 6 times in a row, with the plan to stop immediately after the first win? Plus, (highly) increasing the stake every time we play. Wouldn't this strategy be quite safe, considering the probability of losing 6 consecutive times is approximately 0.5⁶?
The problem with this approach (known as a Martingale strategy) is that the upside is constrained and the downside is much larger, even though it is less probable. If we had a game with 50/50 odds (like a coin flip), we could plan to double our bet each round and stop whenever we win. So if we bet $5 and win we stop. But if we lose we have to bet $10 on the second round. If we win, we're still only up by $5 overall, but if we lose we have to bet $20 for the 3rd round to cover previous losses and still be up $5. This continues for each subsequent round. This means that the maximum we could win at any point is only $5 (because that's when we stop), but the total we could lose would be $315 if we were really unlucky and lost all 6. Would you want to risk losing a total of $315 in order to win $5? I wouldn't consider this a "safe" strategy because of how much you might have to risk in order to get a small gain. The coin doesn't remember the previous flips, so each round has 50/50 odds, but in later rounds you're risking very large losses for a tiny overall gain (your wallet does remember the previous losses 😅). You probably wouldn't want to play a single game where you'd have to risk $160 to win $5 with 50/50 odds (which is essentially what you'd be doing in round 6), and you're probably only willing to take that risk because of the previous sunk costs of losing rounds 1-5. In order to nearly guarantee a gain of $5 we'd need a very large bankroll relative to our first bet because we don't know how long we might have to play (it might be more than 6 before we win). In practice this is why casinos have maximum stakes, so you can't carry this on indefinitely until you win (eventually you won't be allowed to double your bet) even if you had an infinite bankroll. And, of course, they also don't offer 50/50 odds, even for something like red/black on roulette since there are 2 green spaces, giving the house a slight edge on every round.
@@PsychExamReview oh, there's a term for my idea I didn't know about yet. Highly appreciate you mentioned it. Just as I appreciate your detailed explanation, of course. Thank you!
All practice question videos are available in this playlist, or you can find one question video at the end of each unit playlist: Psychology Practice Questions - ru-vid.com/group/PLkKvotUGCyLdlWlX1XbKssmpd03V5S__Y
We could say that data is referring to specific and carefully collected measurements, which can then provide evidence for or against a hypothesis that tries to explain some phenomenon. In this case the data would be the skull measurements and observed faculties, and these would provide possible evidence for the existence of a relationship between skull shapes and mental abilities. Hope this helps!
If we are not duel why we feel sad , love , disgrace , hate and other feelings and you know no matter how you explaine no cell can feel love or sad ! I learn we have soul and body not a single body only
This is a deep philosophical question and a monist approach in psychology assumes that these feelings result from physiological patterns of activity from millions of cells communicating. This assumption may not be correct, but within psychological research there's generally a focus on providing physiological explanations for all thoughts, feelings, and emotions, rather than non-material explanations that can't be directly observed. It may be the case that we do have a non-material soul, but this type of explanation would generally be considered a philosophical or theological explanation rather than a formal scientific psychological explanation for thought or behavior. Hope this is clearer!
I had this surgery, partially separated, not fully separated. Had trouble feeling one side of my body after the surgery and the disconnection syndrome absolutely sucked.
