Sampling fluctuations resulting from the sampling of test items

Sampling fluctuations resulting from the sampling of test items rather than of examinees are discussed. It is shown that the Kuder-Richardson reliability coefficients actually are measures of this type of sampling fluctuation. Formulas for certain standard errors are derived; in particular, a simple formula is given for the standard error of measurement of an individual examinee's score. A common misapplication of the Wilks-Votaw criterion for parallel tests is pointed out. It is shown that the Kuder-Richardson formula-21 reliability coefficient should be used instead of the formula-20 coefficient in certain common practical situations.Most of the work reported here was carried out under contract with the Office of Naval Research.

Reversing roles: a cognitive strategy for undoing memory deficits associated with token status

Tested whether having tokens (Ts) adopt the role of judge reduces cognitive deficits; examined several hypotheses to explain these deficits. In 3 experiments, Ss were asked to remember as many as possible of opinions exchanged in a group interaction with 3 actors. Experiment 1 demonstrated that judging majority members helped gender Ts improve their memory and ruled out self-denigration as a mediator of token deficits. Experiment 2 indicated that judging others was effective regardless of whether the others were said to know about it or not, ruling out insulation from evaluative scrutiny as a viable mediator for the judge role. Experiment 3 suggested the judge role restores completely the Ts, cognitive capacities and ruled out heightened responsibility as an explanation for the improved memory of judges. This work suggests that Ts may perform better if they can restructure cognitively their social environments.     

Estimating the imputed social cost of errors of measurement

If a loss function is available specifying the social cost of an error of measurement in the score on a unidimensional test, an asymptotic method, based on item response theory, is developed for optimal test design for a specified target population of examinees. Since in the real world such loss functions are not available, it is more useful to reverse this process; thus a method is developed for finding the loss function for which a given test is an optimally designed test for the target population. An illustrative application is presented for one operational test.This work was supported in part by contract N00014-80-C-0402, project designation NR 150-453 between the Office of Naval Research and Educational Testing Service.

The real symmetry problem(s) for wide-scope accounts of rationality

You are irrational when you are akratic. On this point most agree. Despite this agreement, there is a tremendous amount of disagreement about what the correct explanation of this data is. Narrow-scopers think that the correct explanation is that you are violating a narrow-scope conditional requirement. You lack an intention to x that you are required to have given the fact that you believe you ought to x. Wide-scopers disagree. They think that a conditional you are required to make true is false. You aren’t required to have any particular attitudes. You’re just required to intend to x or not believe you ought to x. Wide-scope accounts are symmetrical insofar as they predict that you are complying with the relevant requirement just so long as the relevant conditional is true. Some narrow-scopers object to this symmetry. However, there is disagreement about why the symmetry is objectionable. This has led wide-scopers to defend their view against a number of different symmetry objections. I think their defenses in the face of these objections are, on the whole, plausible. Unfortunately for them, they aren’t defending their view against the best version of the objection. In this paper I will show that there is a symmetry objection to wide-scope accounts that both hasn’t been responded to and is a serious problem for wide-scope accounts. Moreover, my version of the objection will allow us to see that there is at least one narrow-scope view that has been seriously underappreciated in the literature.     

Meditative dialogue: tuning in to the music of family therapy

Meditative dialogue is a mindfulness method through which families and their therapists are able to access the present moment and develop acceptance, non‐judgmental attitudes and attunement with one another and with the music that is always present in their lives. This process can be used to deepen empathic connections, tap into creative forces and loosen and encourage embodied and flexible interactions that alter patterns and cultivate openness to possibility and to change.     

The Mother Teresa Effect: Counterproductive Effects of Touching an Altruist’s Possessions on Charitable Giving

Charities that recruit famous humanitarians, or obtain celebrity endorsements, may promote products associated with these altruistic superstars in an effort to increase donations. Previous research supports that “superstar” role models can promote desirable behavior. Charitable organizations may assume if people handle a product associated with a famous humanitarian, they will be inspired and more motivated to donate as a result. An opposite possibility is that physically handling reminders of an extreme altruist may result in contrast effects. Such positive exemplars may result in more negative perceptions of one’s own charitable behavior, and decrease the perceived efficacy of one’s own contributions. In two studies, participants did or did not touch items said to have belonged to a very altruistic person (Experiment 1) or to Mother Teresa (Experiment 2). Compared to participants in non-touch and other control conditions, those who physically touched items said to belong to an altruist subsequently donated fewer raffle tickets to charity. The results are related to theories of perceived efficacy, metacognitive processes, and the counterproductive influence of extremely positive role models.
