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.
@PsychExamReview
@PsychExamReview Күн бұрын
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.

@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.

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.

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?
@PsychExamReview
@PsychExamReview 17 күн бұрын
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.

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.

@PsychExamReview

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'd recommend starting with a general overview so you can become aware of the different areas of psychology and some of the general principles for thinking about psychological topics. It's important to have a sense of the main approaches (biological, behavioral, cognitive, sociocultural) before choosing a specific area so that you know how different perspectives would approach it; what types of questions each would consider and how these might fit together. I have a playlist of all of my intro psych videos in order on my channel, or you could choose from the playlists by unit.

@@AHMEDTANJAWI-ms5qv What you'll discover is that this is actually an infinitely complex question (though that shouldn't be discouraging!). Trying to fully understand why someone has a particular thought or engages in a certain behavior means that we would need to consider their biology (genes, hormones, neurotransmitters, brain function) both at that moment and potentially extending over millions of years of the evolutionary past, their previous experience with the world (rewards, punishments, & other environmental factors, which also influence gene expression) leading up to that moment, their patterns of thinking, language use, and stored knowledge and perceptions of the world (called schema) as well as potential distortions & biases that may influence which of these they are drawing from, as well as their culture, past social experiences and relationships, and their unique interpretation of this particular social interaction. Identifying a definitive answer that incorporates all of these is essentially impossible, but that doesn't mean that we can't draw any conclusions or consider the most important factors for some types of thoughts or behaviors. So psychologists using different approaches may focus on the importance of different aspects for certain situations, but this doesn't mean that one explanation will always be correct or will be the "best" explanation for other thoughts or behaviors or for other individuals (though some psychologists occasionally seem to forget to keep this in mind). Hopefully this glimpse of the complexity of human thought and behavior inspires you to want to learn more; don't accept simple answers and remember there are almost always more possibilities to consider.

It's not impossible for most people to be above average. If you have 99 people with an IQ of 100 and 1 person with an IQ of 90, 99% will have an IQ that is above average.
@PsychExamReview
@PsychExamReview Ай бұрын
You're right, this is technically possible with small sample sizes where the mean can be a poor measure of central tendency and median or mode would be better (both would be 99 in this case). This is also a good reminder to students not to focus on the "class average" on an exam in a small class, because 1 or 2 low scores can make most students believe they scored "above average". But this is much less likely to occur with large sample sizes and when estimating the population mean for a trait that is normally distributed.

@PsychExamReview
@PsychExamReview 26 күн бұрын
Great question, this formula is just a broad-sense estimate, so there are some limitations that can inflate the heritability and in some cases this can lead to heritability greater than 1.0, which is obviously impossible. This calculation doesn't consider that MZ twins may have more shared environment than DZ twins and gene-environment interactions may make their environments more similar (the formula assumes these are the same for MZ and DZ twins). As a result this can misattribute some environmental factors to genetics. Hope this helps!

Great question, I probably should have worded this more clearly; in sufferers normal pleasures aren't present, but they are present in healthy people. The name "anhedonia" means "without pleasure" so healthy people do have pleasure responses to things like food, hobbies, etc. but this pleasure is absent in sufferers, so saying they show anhedonia means the normal pleasure responses are not present, making it a negative symptom.
