Fatigue, sleep loss, and confidence in judgment

Sixty-four adults participated in a study examining the accuracy of metacognitive judgments during 28 hr of sleep deprivation (SD) and continuous cognitive work. Three tasks were studied (perceptual comparison, general knowledge, and mental addition), collectively spanning a range of cognitive abilities and levels of susceptibility to SD. Subjective and objective measures of sleepiness confirmed the expected patterns of increasing fatigue with SD. Participants displayed differing levels of metacognitive abilities across tasks, but traditional indices of the confidence-accuracy relation (i.e., calibration, resolution, over- and underconfidence), as well as the accuracy of pre- and posttask estimates of performance, remained stable over the SD period. The findings suggest that people can accurately assess their own cognitive performance when deprived of 1 night of sleep and that this ability need not be based on subjective estimates of sleepiness. The implications and limitations of the study are discussed and directions for future research are proposed.     

Response scatter in measuring changing-loudness aftereffects: evidence for simplified processing of auditory motion-in-depth and potential collision

Researchers have postulated 2 mechanisms for processing auditory motion: a direct mechanism processing motion itself and an indirect mechanism sensitive to location over discrete points in time. Measuring aftereffects of azimuthal motion by nulling entails scattered responding, which is attributed to a conflict between direct and indirect mechanisms. In this experiment, the author obtained nulls following adaptation to changing sound level, a property of approaching or receding sound sources, and for nonadaptation. Test stimuli ranged in duration from 1.0 to 2.5 s. Longer test stimuli evinced reductions in both changing-loudness aftereffects and the associated response scatters. However, the latter matched the nonadaptation response scatters. The author suggests that judging longer test stimuli is easier, so an indirect mechanism need not be invoked. Simplified processing of changing sound level may underlie the rapid responses required for potential collision.     

When sad is better than happy: Negative affect can improve the quality and effectiveness of persuasive messages and social influence strategies

Based on recent affect-cognition theories and research on social influence strategies, four experiments predicted and found that people in negative mood produced higher quality and more effective interpersonal persuasive messages than did people in positive mood. This effect was obtained for messages advocating both popular and unpopular positions (Experiments 1 and 2), and arguments produced in negative mood actually induced greater attitude change in naïve recipients (Experiment 3). Experiment 4 replicated these effects in an interactive situation, and mediational analyses showed that mood influenced processing style, resulting in the production of more concrete and thus more effective messages when in a negative mood. The role of negative affect in information processing and the production of interpersonal influence strategies in particular is discussed, and the implications of these findings for everyday interaction strategies, and for contemporary affect—cognition theorizing are considered.     

Is death really the worm at the core? Converging evidence that worldview threat increases death-thought accessibility

According to terror management theory, if the cultural worldview protects people from thoughts about death, then weakening this structure should increase death-thought accessibility (DTA). Five studies tested this DTA hypothesis. Study 1 showed that threatening Canadian participants' cultural values (vs. those of another culture) increased DTA on a word-fragment completion task. Study 2 showed that when participants could dismiss the threat, DTA remained low. Study 3 replicated the results of Study 1, but DTA was measured using a lexical decision task. Response latencies to death, negative, and neutral content were measured. Worldview threat increased DTA relative to accessibility for negative and neutral content. Study 4 showed that the DTA effect emerged independently of the arousal of anger or anxiety. Finally, Study 5 demonstrated that participants with a pro-creation (vs. pro-evolution) worldview had higher DTA after reading an anti-creation article. Discussion focused on theoretical implications and directions for further research.     

Deceptiveness on the PAI: a study of naïve faking with psychiatric inpatients

In this study, we sought to explore the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales (Negative Impression Management [NIM] and Positive Impression Management [PIM]) and indexes (Malingering index, Defensiveness index [DEF]; Morey, 1993, 1996; Cashel Discriminant Function; Cashel, Rogers, Sewell, & Martin-Cannici, 1995; and Rogers Discriminant Function [RDF]; Rogers, Sewell, Morey, & Ustad, 1996) to identify differences in profiles completed by psychiatric inpatients under standardized instructions (Time 1) and after random assignment (Time 2) to a fake good (n=21), fake bad (n=20), or retest (n=21) scenario. Repeated measures analysis of variance revealed a significant interaction effect. Whereas the retest group did not show any significant changes on the PAI variables from Time 1 to Time 2, both faking groups showed changes in expected directions. Discriminant function analyses revealed that NIM, RDF, and lower scores on DEF best differentiated between the faking bad and retest groups. PIM was the only nonredundant significant score discriminating the faking good and retest groups. Cutoffs for these scales and indexes established in prior research were supported using diagnostic efficiency statistics. Results suggest that NIM and RDF in faking bad scenarios and PIM in faking good scenarios are most sensitive to unsophisticated attempts to dissimulate by inpatient psychiatric patients.     

Internet stings directed at pedophiles: A study in philosophy and law

This article is published under rules given in “Multiple Publication Reconsidered,”Journal of Information Ethics 7 (Fall 1998): (2)47-53 and “Multiple Publication Reconsidered II,”Journal of Information Ethics 15 (Spring 2006): (1)5-7 and is substantially revised from 15Widener Law Journal 47 (2005), per refereeing, and also has an additional final section. The article is intended to, in Sections I and II, flesh out and put within a metaphilosophical framework the theoretical argument first made in 2002 in “Do Internet Stings Directed at Pedophiles Capture Offenders or Create Offenders? And Allied Questions” (Sexuality &; Culture 6(4): 73–100), with some modifications (See note 14). Where there are differences, I stand by this version as the final version of the argument. Section III addresses three experimental or empirical studies which might be thought to contradict or confirm the data of the 2002 study. Section IV compares what we have done with the one other jurisprudential argument made by Summer 2005. Section V discusses why, despite the evidence and the arguments, these sting operations are popular with prosecutors and the public alike. Section VI comments on why my empirical study dating to 2002 does not appear to have gained wide acceptance, and what, if anything, can be said about this.     

Identifying effective mental health interventions for American Indians and Alaska Natives: a review of the literature

The pursuit of evidence-based practice (EBP) within the mental health professions has contributed to efficacious clinical intervention for individuals struggling with mental health problems. Within the context of the EBP movement, this article reviews the treatment outcome literature for mental health interventions directed specifically toward American Indians and Alaska Natives experiencing psychological distress. Fifty-six articles and chapters pertaining to the treatment of Native Americans with mental health problems were identified, though the vast majority of these did not systematically assess outcomes of specified treatments for Native American clients under scientifically controlled conditions. Of just nine studies assessing intervention outcomes, only two were controlled studies with adequate sample sizes and interpretable results relative to the identification of EBP among American Indians and Alaska Natives. The advantages and limitations of EBP for treatment of Native American mental health problems are discussed.     

Marriage and the Public Good

In this article I seek to address some misunderstandings inarguments about same sex-marriage. I do this by evaluating severalviews on homosexuality and marriage. My central aim is to showthat a rejection of same-sex marriage does not depend upon theview that homosexual acts are immoral or disordered. Rather,one must examine sexual acts in light of public goods that areat stake. I also argue that the Christian understanding of marriageand sexuality offers more than a set of prohibitions againstcertain sexual acts. Rather, it offers reasonable principlesby which to evaluate the relationship between sexual acts andthe public good.     

Presumed consent for organ preservation in uncontrolled donation after cardiac death in the United States: a public policy with serious consequences

Organ donation after cessation of circulation and respiration, both controlled and uncontrolled, has been proposed by the Institute of Medicine as a way to increase opportunities for organ procurement. Despite claims to the contrary, both forms of controlled and uncontrolled donation after cardiac death raise significant ethical and legal issues. Identified causes for concern include absence of agreement on criteria for the declaration of death, nonexistence of universal guidelines for duration before stopping resuscitation efforts and techniques, and assumption of presumed intent to donate for the purpose of initiating temporary organ-preservation interventions when no expressed consent to donate is present. From a legal point of view, not having scientifically valid criteria of cessation of circulation and respiration for declaring death could lead to a conclusion that organ procurement itself is the proximate cause of death. Although the revised Uniform Anatomical Gift Act of 2006 provides broad immunity to those involved in organ-procurement activities, courts have yet to provide an opinion on whether persons can be held liable for injuries arising from the determination of death itself. Preserving organs in uncontrolled donation after cardiac death requires the administration of life-support systems such as extracorporeal membrane oxygenation. These life-support systems can lead to return of signs of life that, in turn, have to be deliberately suppressed by the administration of pharmacological agents. Finally, allowing temporary organ-preservation interventions without expressed consent is inherently a violation of the principle of respect for a person's autonomy. Proponents of organ donation from uncontrolled donation after cardiac death, on the other hand, claim that these nonconsensual interventions enhance respect for autonomy by allowing people, through surrogate decision making, to execute their right to donate organs. However, the lack of transparency and the absence of protection of individual autonomy, for the sake of maximizing procurement opportunities, have placed the current organ-donation system of opting-in in great jeopardy. Equally as important, current policies enabling and enhancing organ procurement practices, pose challenges to the constitutional rights of individuals in a pluralistic society as these policies are founded on flawed medical standards for declaring death.
