- On the misperception of variabilityYaakov Kareev
Goldie Rotman Center for Cognitive Science and Education, School of Education, The Hebrew University, Jerusalem, Israel
J Exp Psychol Gen 131:287-97. 2002..Results of 5 experiments show that people use sample variability, uncorrected for sample size, in tasks in which a correction is normatively called for, and indeed perceive variability as smaller than it is...
- Judge for yourself: reply to Evans and Buehner (2011)Yaakov Kareev
School of Education and The Center for the Study of Rationality, The Hebrew University of Jerusalem, Jerusalem 91905, Israel
J Exp Psychol Learn Mem Cogn 37:1595-8. 2011..However, whereas Evans and Buehner only reiterate this point (and present it as novel), we continue from there and show that small samples are likely to result in clear data...
- Seven (indeed, plus or minus two) and the detection of correlationsY Kareev
Goldie Rotman Center for Cognitive Science and Education, School of Education, Hebrew University of Jerusalem, Israel
Psychol Rev 107:397-402. 2000..for which each variable is a valid predictor of the other) first outnumber correlations for which this is not the case. Capacity limitations are thus shown to maximize the chances for the early detection of strong and useful relations...
- Correct acceptance weighs more than correct rejection: a decision bias induced by question framingYaakov Kareev
School of Education and The Center for the Study of Rationality, The Hebrew University of Jerusalem, Jerusalem, 91904, Israel
Psychon Bull Rev 18:103-9. 2011..A regression analysis revealed that, in addition, individuals' decision criteria reflected their learning experiences, with the weight of hits being greater than that of correct rejections...
- Base rates, contingencies, and prediction behaviorYaakov Kareev
School of Education and Center for the Study of Rationality, Hebrew University of Jerusalem, Israel
J Exp Psychol Learn Mem Cogn 35:371-80. 2009..In the second, in which the contribution of contingency over base rate is manipulated, they study participants' willingness to forgo a costly predictor. Results indicate a close correspondence between ExpPA and behavior...
- Choosing between adaptive agents: some unexpected implications of level of scrutinyYaakov Kareev
The Center for the Study of Rationality, The Hebrew University of Jerusalem, Jerusalem, Israel
Psychol Sci 18:636-41. 2007..We conclude by pointing out that small-sample-based, error-prone decisions may also maintain competition and diversity in the environment...
- Nonproportional sampling and the amplification of correlationsYaakov Kareev
School of Education and Center for Rationality, The Hebrew University of Jerusalem, Jerusalem, Israel
Psychol Sci 17:715-20. 2006..People's sampling behavior thus resembles that of a research designer who maximizes the chance of detecting a relationship, at the cost of diminished accuracy in estimating its strength...
- The effects of problem content and scientific background on information search and the assessment and valuation of correlationsShira Soffer
School of Education, The Hebrew University of Jerusalem, Jerusalem 91905, Israel
Mem Cognit 39:107-16. 2011....
- The dynamics of choice in a changing world: Effects of full and partial feedbackJudith Avrahami
Federmann Center for the Study of Rationality and School of Education, Hebrew University of Jerusalem, Edmund Safra Campus, Jerusalem, 91904, Israel
Mem Cognit . 2016..As expected, the other manipulated variables (change frequency, the options' values, and the difference between them) had no effect on the dynamics of behavior...
- Do the weak stand a chance? Distribution of resources in a competitive environmentJudith Avrahami
School of Education and The Center for the Study of Rationality, The Hebrew University of Jerusalem
Cogn Sci 33:940-50. 2009..Our results indicate that they do...
- Does decision quality (always) increase with the size of information samples? Some vicissitudes in applying the law of large numbersKlaus Fiedler
Psychology Department, University of Heidelberg, Heidelberg, Germany
J Exp Psychol Learn Mem Cogn 32:883-903. 2006..The relative advantage of small samples is most apparent when information loss is low, when the threshold is high relative to the ecological contingency, and when the sampling process is self-truncated...
