In Defence of Entrapment in Journalism (and Beyond)

The use of 'proactive' methods of newsgathering in journalism is very frequently condemned, from within and without the media. I argue that such condemnation is too hasty. In the first half of the paper, I develop a test which distinguishes between legitimate and illegitimate uses of proactive methods by law enforcement agencies. This test combines the virtues of the standard objective and subjective tests usually used, while avoiding the defects of both. I argue that when proactive methods pass this test, they are always legitimate; but that in addition they are sometimes mandatory. In the second half, I apply this test to journalism. I show that actual uses of proactive methods by journalists pass the test, and are therefore (at least) permissible. There are other ethical considerations which are relevant to the use of such techniques by journalists, which ought to be taken into account before it is decided to employ such methods, but I show that they are rarely of sufficient weight to render proactive newsgathering impermissible.     

Assessing heterogeneity in meta-analysis: Q statistic or I2 index?

In meta-analysis, the usual way of assessing whether a set of single studies is homogeneous is by means of the Q test. However, the Q test only informs meta-analysts about the presence versus the absence of heterogeneity, but it does not report on the extent of such heterogeneity. Recently, the I(2) index has been proposed to quantify the degree of heterogeneity in a meta-analysis. In this article, the performances of the Q test and the confidence interval around the I(2) index are compared by means of a Monte Carlo simulation. The results show the utility of the I(2) index as a complement to the Q test, although it has the same problems of power with a small number of studies.     

Individualized assessment moderates the impact of HIPAA privacy rules

In this comment, I express appreciation of Erard's (this issue) review, and urge psychologists to continue to protect test security. I disagree with Erard's belief that the Health Insurance Portability and Accountability Act of 1996 (HIPAA) is salient for nonhealth forensic issues. I then review some ways in which individualized assessment practices can moderate the negative impact of the HIPPA privacy rules. Assessors can use tests as a ground forjoint exploration of the client's experience, behavior, and their contexts. Clients may later ask for a review of test data and collaborative life findings, but they rarely are interested in acquiring test records. Attorneys, after discovering that assessment conclusions are based largely on events/contexts provided by the client and others, are less interested in acquiring test records that the psychologist used as tools rather than as evidence for conclusions.

A closer look at the effect of preliminary goodness-of-fit testing for normality for the one-sample t-test

Student's one-sample t-test is a commonly used method when inference about the population mean is made. As advocated in textbooks and articles, the assumption of normality is often checked by a preliminary goodness-of-fit (GOF) test. In a paper recently published by Schucany and Ng it was shown that, for the uniform distribution, screening of samples by a pretest for normality leads to a more conservative conditional Type I error rate than application of the one-sample t-test without preliminary GOF test. In contrast, for the exponential distribution, the conditional level is even more elevated than the Type I error rate of the t-test without pretest. We examine the reasons behind these characteristics. In a simulation study, samples drawn from the exponential, lognormal, uniform, Student's t-distribution with 2 degrees of freedom (t(2) ) and the standard normal distribution that had passed normality screening, as well as the ingredients of the test statistics calculated from these samples, are investigated. For non-normal distributions, we found that preliminary testing for normality may change the distribution of means and standard deviations of the selected samples as well as the correlation between them (if the underlying distribution is non-symmetric), thus leading to altered distributions of the resulting test statistics. It is shown that for skewed distributions the excess in Type I error rate may be even more pronounced when testing one-sided hypotheses.     

Keep 'Gestalt' in the name of the test: the curious name permutations of the Bender-Gestalt Test

The Bender-Gestalt Test is often referred to in the literature by several different names, or just as the Bender Test, without the term Gestalt. As a consequence, the figures of the test are frequently called Bender figures or Bender designs, terms which are unjustified and misleading because the figures have been taken from Wertheimer's classical study of Gestalt laws. In this article, I trace the beginnings of the name of the test and its curious permutations, and I advocate the retention of the term Gestalt in the name of the test for logical and historical reasons.     

Personality assessment without borders: adaptation of the MMPI-2 across cultures

In contemporary psychology, personality assessment knows few national or cultural boundaries. Psychological tests developed in one country are often translated and adapted into cultures that might appear to be greatly different from the country of origin. In this article, I address the factors that are important to international test adaptation and examine problems that can adversely affect cross-cultural test research programs. I address qualities important for verifying the accuracy and adequacy of cross-cultural assessment. I review the extensive adaptation of the MMPI (Hathaway & McKinley, 1940) and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), the most frequently used personality measure. I highlight several contemporary research trends in international personality assessment.

The mental accounting of sunk time costs: why time is not like money

The sunk‐cost effect, an irrational attention to non‐recoverable past costs while making current decisions, has been documented widely in the domain of monetary costs. In this paper, I study the effect of past time investments on current decisions. In three experiments using choice situations, I demonstrate that the sunk‐cost effect is not observed for past investments of time, but the effect reappears when the investments are expressed as monetary quantities. I further propose that this ‘pseudo‐rationality’ is due to the fact that individuals lack the ability to account for time in the same way as they account for money. In two additional experiments, I facilitate the accounting of time and show that the irrational sunk‐cost effect reappears. In a final experiment, I test my propositions in a setting where subjects make real investments of time and subsequently make real choices. Copyright © 2001 John Wiley & Sons, Ltd.     

Epistemic Contextualism: An Idle Hypothesis

Epistemic contextualism is one of the most hotly debated topics in contemporary epistemology. Contextualists claim that ‘know’ is a context-sensitive verb associated with different evidential standards in different contexts. Contextualists motivate their view based on a set of behavioural claims. In this paper, I show that several of these behavioural claims are false. I also show that contextualist test cases suffer from a critical confound, which derives from people's tendency to defer to speakers’ statements about their own mental states. My evidence consists in results from several behavioural experiments. I conclude that contextualism is an idle hypothesis and I propose some general methodological lessons.

Manipulations of vasopressin alter aggression differently across testing conditions in monogamous and non‐monogamous Peromyscus mice

Differences in the distribution of arginine vasopressin (AVP) and a subtype of AVP receptors, the V_1a receptor, may explain dissimilarities in social behavior of monogamous and non‐monogamous rodents. Intracerebroventricular infusions of AVP and a V_1a antagonist were used in sexually naive males of two mouse species, the monogamous and highly aggressive California mouse (Peromyscus californicus) and the non‐monogamous and less aggressive white‐footed mouse (P. leucopus), to begin testing the interaction between the social system of a species and the effects of AVP on aggression. Two testing conditions, the resident‐intruder aggression test (R‐I) and the neutral arena aggression test, were used because they may differ in function and underlying biological mechanisms. In the R‐I test, administration of the antagonist lengthened attack latencies in California mice. In contrast, blocking V_1a receptors did not alter attack latencies in the R‐I test in white‐footed mice or in the neutral arena aggression test in both species. AVP also did not alter aggression in either species in either behavioral test. Overall, these results suggest that AVP may be more likely to be associated with offensive aggression as measured in the R‐I test than with neutral arena aggression and that the effects of AVP manipulations may differ between monogamous and non‐monogamous rodents.

A comparison of two‐stage procedures for testing least‐squares coefficients under heteroscedasticity

This study explores the performance of several two‐stage procedures for testing ordinary least‐squares (OLS) coefficients under heteroscedasticity. A test of the usual homoscedasticity assumption is carried out in the first stage of the procedure. Subsequently, a test of the regression coefficients is chosen and performed in the second stage. Three recently developed methods for detecting heteroscedasticity are examined. In addition, three heteroscedastic robust tests of OLS coefficients are considered. A major finding is that performing a test of heteroscedasticity prior to applying a heteroscedastic robust test can lead to poor control over Type I errors.     

Book Review of Sattler and Ryan,Assessment With the WAIS–IV

The Rorschach and Minnesota Multiphasic Personality Inventory (MMPI) are among the most widely used personality assessment tools. However, there is little guidance in the literature about their combined use. In this article, I discuss conceptual and methodological issues of combining these widely used psychological tests, including the use of the test battery and the necessity of rationales for test utilization. Methodological approaches to integrating the test findings are discussed, including score, construct, test by test, and theory-based integrative approaches. The value of a person-centered interpretive and integrative focus is affirmed.     

The Suppositional Ramsey Test and Decision-Instability

I analyse the relationship between the Ramsey Test (RT) for the acceptance of indicative conditionals and the so-called problem of decision-instability. In particular, I argue that the situations which allegedly bring about this problem are troublesome just in case the relevant conditionals are evaluated by non-suppositional versions, e.g. causal/evidential, of the test. In contrast, a suppositional RT, by highlighting the metacognitive nature of the evaluation of indicative conditionals, allows an agent to run a simulation of such evaluation, without yet committing her to the acceptance of such conditionals. I conclude that a suppositional interpretation of RT is superior to its non-suppositional counterparts and by briefly showing that a suppositional RT is compatible with a deliberational decision theory.     

Trial and intertrial durations in Pavlovian conditioning: issues of learning and performance

Four experiments assessed the effects of trial (T) and intertrial (I) durations on magazine approach behavior in rats. In Experiments 1 and 2, different groups of animals were conditioned with various combinations of I and T durations. The rate of acquisition, in terms of the number of trials required to reach various acquisition criteria, generally was faster in groups trained with large I:T ratios. There also were differences in rate of acquisition and terminal response rates between groups trained with identical I:T ratios but with different absolute I and T durations. Differences evident at the end of conditioning persisted during a common test with various combinations of I and T durations. Experiments 3 and 4 provided a more specific test of the predictions of 2 general classes of theories and found results that were consistent with those theories that characterize group differences as indicative of differences in learning, rather than in performance.
