Psych U4 Q's Thread!

Question... I know that generalisations cannot be made if results are not statistically significant but can conclusions be made? And is the conclusion just if the hypothesis is supported or not?

I don't think either can with the results are not statistically significant.

Great thank you!

Does adaptive plasticity serve any other purpose other than for brain damage? I once had "to maximise functions (e.g. pianists have larger cortical area for finger control)" But apparently developmental plasticity occurs "in response to experience and learning throughout lifespan"... which the pianists thing would come under, right? So confused.

That's what I thought but then why does the STAV 2011 exam say that the results are not significant to just go on to say that a conclusion can be made which supports the hypothesis :/

Adaptive plasticity
-to enable adjustment to experience
-compensate for lost function
-maximise remaining functions in the event of a brain damage

A conclusion cannot be made and hence nor a generalisation when:

The sample is not representative of the population
Sampling is not random
P-value of over 0.05
Obvious confounding variables
Breached ethical principles

Is this correct?

[jwongton]

^ I'd really like to know for sure about supporting/not supporting a hypothesis too

[harlequinphoenix]

Sounds pretty right monkey, I am yet to have a last skim over research methods later tonight but I THINK that, if the results are significant and there's no CVs yadayada then a conclusion can be made, but that doesn't mean a generalisation can automatically be made - the representativeness of the sample HAS to be all good before a generalisation can be made am I right?

also if the hypothesis is rejected but the experiment  is statistically significant what do you say about the results?

[mattmcmahon]

I thought that they could be made when ethical principles were breached? I'm not 100% sure though


Does anybody have a clear distinction between demand characteristics and experimenter effects? Cause the difference a bit unclear to me

Also, with Bandura's 1963a study, was there any difference between the results of a physical model, the model on screen or the cartoon model?

[roxannie136]

whats the difference between meditation and relaxation?

[papertissue]

Meditation involves going into an altered states of consciousness while relaxation does not.

In 1963a, viewing the real-life model made showing aggression to the doll more likely. The cartoon, least likely.

As for demand characteristics, try reading up on this: http://knol.google.com/k/gblackhart/demand-characteristics/2iym3t7edxw1s/2#

I suppose demand characteristics can refer to more general cues while experimenter effects have to be made by the experimenter saying/doing something that shows their bias.

[mattmcmahon]

Thanks for that! so is an experimenter effect a type of demand characteristic or are they just very similar?

[roxannie136]

thanks

I think conclusions can be made after breaching ethical principles, like the Little Albert experiment contributed a lot to the knowledge of classical conditioning, and I assume conclusions were drawn. If a study breached ethical principles, it is likely that the research wouldn't be allowed to go forward in the first place anyway. I could be wrong though.
