An experiment that is high in internal validity will be able to be replicated at a later date and yield similar results.]]> 2017-11-12 16:47:39 UTC https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/206000864 https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207137703 - Accurate measurements due to standardised procedure
- Easier to replicate in a controlled environment
- Experiments which are closer to real world scenarios have a greater degree of ecological validity

(explorable, 2017) for example, an experimenter could influence the results consciously or unconsciously via the way they word a question or by certain verbs they use just like in the Loftus and palmer study thus impacting on the results (1974) 
this could be reduced via double blind controls for example, not knowing the type of variable that they are giving to the participant.]]> 2017-11-15 11:48:44 UTC https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207138025 https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207138582 Standardized procedures are they instructions the participants will recieve before taking part in the experiment for example: 
same diet
same amount of caffeine
similar ages
similar IQ
time of day - same
relativley same sleep pattern 

The standardised procedures help make the experiment be more reliable because the factors that could contribute to the experiment and vary results are made similar between the participants to avoid extraneous variables affecting results. ]]> 2017-11-15 11:51:18 UTC https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207138582 https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207138801 demand characteristic is the hint or cue that makes participants aware of what the experimenter expects to find or how participants are expected to behave. Demand characteristics can change the outcome of an experiment because participants will often alter their behavior to meet certain exception 

reducing demand characteristics?
> placebo effect 
Participants unaware of hypothesis in order to prevent participants being influenced


impacts- results less accurate/reliable/validity ]]> 2017-11-15 11:52:25 UTC https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207138801 https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207139152 - Controlled environment is not replicated in real world situations
- Higher chance of subjects displaying demand characteristics
- Usefulness of ecological validity much debated amongst experts]]> 2017-11-15 11:53:53 UTC https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207139152 https://padlet.com/victoria_hindle/vve0ne37z3s6/wish/207140064 They use  manipulated  variables more  than field experiment.
Reduce biased experiment
