PSYC19H3 Chapter Notes - Chapter 2: Brian Nosek, Self-Control, Ego Depletion
Replication Crisis & Importance of Self Control Part 2
Replication Crisis is My Crisis, Michael Inzlicht
Many studies unsupported or irreproducible
oPower posing may not boost confidence and increase circulating hormones
oReminding people of money may not influence opinions or behaviour
File drawer effect – studies with negative outcomes are tucked away
oData flexibility leads to false positives, size of drawer is unknown, process may be
unknown
oThink we’re chasing real & robust things, but actually puffs of smokes
Makes us question if certain phenomenon are actually real despite studies
oEgo depletion: limited reservoir of energy for exercising self control & mental
disciplines
oStereotype threat: people consider selves at risk of negative stereotype about social
group
Can impact performances on tests, in jobs, other situations
Problems are solvable
oMore statistical power, greater transparency surrounding null results, confirmatory
studies
How Reliable are Psychology Studies, Ed Yong
The Reproducibility Project by Brian Nosek – to repeat experiments for replicability
oPublication of studies with impossible effects (precognition)
oFailure to replicate results of classic textbook experiments
oSome prominent cases of outright fraud
Problems are well documented
oPublication bias: journals tend to only publish positive outcomes
oP hacking: questionable practices, attempt to torture positive result out of
ambiguous data
Check for statistically significant results before collecting more data
Report only the results of successful experiments
oNosek considered effect size of studies (measure strength of phenomenon)
oWithin-subject designs: test same people under different conditions
