Decision‐making in civil litigation: Effects of attorney credibility,evidence strength,and juror cognitive processing

The current study examined the relationship between juror cognitive processing (measured by need for cognition [NFC]), attorney credibility, evidence strength, and civil litigation verdicts (liability, likelihood of causation, and compensatory damages). Participants (N = 446) viewed a videotaped mock civil trial in which the credibility of the attorneys and the strength of the plaintiff's evidence were manipulated. Plaintiff attorney credibility, defense attorney credibility, and strength of evidence interacted with one another for liability verdicts. In the strong evidence condition, the likelihood of a liable verdict was higher for a credible plaintiff attorney than a non‐credible plaintiff attorney when facing a non‐credible defense attorney. In the ambiguous evidence condition, the likelihood of a liable verdict was higher for a credible plaintiff attorney than a non‐credible plaintiff attorney when facing a credible defense attorney. Plaintiff attorney credibility, however, was found to be more influential on jurors’ decision‐making than case evidence for likelihood of causation and compensatory damage award decisions. Participants’ NFC also interacted with plaintiff attorney credibility. High NFC jurors were more influenced by a credible plaintiff attorney than low NFC jurors. Although these findings are counter to common findings in the NFC literature, they conform to a body of literature that supports the notion that jurors view attorney credibility as a piece of case evidence and not a peripheral cue as is often assumed. Thus, the findings indicate that attorneys do matter to the outcomes of cases. Policy and practice implications for attorneys and the courts are discussed.     

The Astounding Assumption of Infinite Life

The multimillennial philosophical discussion about life after death has received a recent boost in the prospect of immortality attained via technologies. In this newer version, humans generally are considered mortal but may develop means of making themselves immortal. If “immortal” means not mortal, thus existing for infinity, and if the proposed infinite‐existing entity is material, it must inhabit an infinite material universe. If the proposed entity is not material, there must be means by which it can shed its material substance and exist nonmaterially. The article examines arguments for how an infinite life would be possible given current physical understanding. The paper considers a Pascalian‐style wager weighing the likelihood of adjusting to existence wholly within a finite universe versus betting on there being some way to construe the universe(s) as a viable medium for infinite beings. Conclusion: the case for a finite being to exist infinitely has little viable support.     

Alcohol-Induced Amnesia and Personalized Drinking Feedback: Blackouts Predict Intervention Response

Alcohol-induced amnesia (“blackout”) is a reliable predictor of alcohol-related harm. Given its association with other negative consequences, experience of alcohol-induced amnesia may serve as a teachable moment, after which individuals are more likely to respond to intervention. To test this hypothesis, alcohol-induced amnesia was evaluated as a moderator of brief intervention effect on (a) alcohol-related consequences and (b) the proposed intervention mediators, protective behavioral strategies and peak blood alcohol concentration (BAC). Baseline alcohol risk measured using the Alcohol Use Disorders Identification Test (AUDIT) was also evaluated as a moderator to rule out the possibility that amnesia is simply an indicator of more general alcohol risk. College students (N = 198) reporting alcohol use in a typical week completed assessments at baseline and 1-month follow-up as part of a larger intervention trial. Participants were randomized to assessment only (AO; n = 58) or personalized feedback intervention (PFI; n = 140). Hierarchical regression was used to examine direct and indirect intervention effects. A significant group-by-amnesia interaction revealed that only PFI participants who had experienced alcohol-induced amnesia in the past month reported decreases in alcohol consequences at 1-month follow-up. The PFI reduced alcohol-related consequences indirectly through changes in peak BAC, but only among those who had experienced amnesia at baseline. In contrast, baseline alcohol risk (AUDIT) did not moderate intervention effects, and use of protective behavioral strategies did not statistically mediate intervention effects. Findings suggest that loss of memory for drinking events is a unique determinant of young adult response to brief alcohol intervention. Normative feedback interventions may be particularly effective for individuals who have experienced alcohol-induced amnesia in the past 30 days.     

Optimal Item Calibration for Computerized Achievement Tests

Item calibration is a technique to estimate characteristics of questions (called items) for achievement tests. In computerized tests, item calibration is an important tool for maintaining, updating and developing new items for an item bank. To efficiently sample examinees with specific ability levels for this calibration, we use optimal design theory assuming that the probability to answer correctly follows an item response model. Locally optimal unrestricted designs have usually a few design points for ability. In practice, it is hard to sample examinees from a population with these specific ability levels due to unavailability or limited availability of examinees. To counter this problem, we use the concept of optimal restricted designs and show that this concept naturally fits to item calibration. We prove an equivalence theorem needed to verify optimality of a design. Locally optimal restricted designs provide intervals of ability levels for optimal calibration of an item. When assuming a two-parameter logistic model, several scenarios with D-optimal restricted designs are presented for calibration of a single item and simultaneous calibration of several items. These scenarios show that the naive way to sample examinees around unrestricted design points is not optimal.

     

Analysis of Hispanic representation and conceptualization in psychology and law research

Hispanics are now the largest minority group in the United States, yet research examining the impact this will have on the American legal system is limited. The first purpose of this article was to synthesize the studies that have been conducted, which have found that Hispanics have a perspective toward the police, the courts and the law, and jury decision making that is unique from those of Caucasians and other ethnic groups. The second purpose of this article was to analyze whether psychology and law research has been conducted in a manner conducive to identifying this unique Hispanic perspective. An analysis of 800 articles published in five psychology and law journals revealed that, while Hispanics were typically conceptualized properly, the proportion of articles devoted to the Hispanic perspective is disturbingly low. To increase understanding of the Hispanic perspective, psychology and law researchers must increase the amount of empirical attention given to Hispanics.     

Saving the best for last: how adults treat social partners of different ages

Older adults report more positive feelings and fewer problems in their relationships than do younger adults. These positive experiences may partially reflect how people treat older adults. Social partners may treat older adults more kindly due to their sense that time remaining to interact with these older adults is limited. Younger (n = 87, age 22 to 35) and older (n = 89, age 65 to 77) participants indicated how positively they would behave (i.e., express affection, proffer respect, send sentimental cards) and what types of conflict strategies they would use in response to hypothetical negative interactions with two close social partners, a younger adult and an older adult. Multilevel models revealed that participants were more avoidant and less confrontational when interacting with older adults than when interacting with younger adults. Time perspective of the relationship partially mediated these age differences. Younger and older participants were also more likely to select sentimental cards for older partners than for younger partners. Findings build on socioemotional selectivity theory and the social input model to suggest that social partners facilitate better relationships in late life.     

Scoring the DSM-IV personality disorders using the Five-Factor Model: development and validation of normative scores for North American, French, and Dutch-Flemish samples

Five-Factor Model (FFM) personality disorder (PD) counts have demonstrated significant convergent and discriminant validity with DSM-IV PD symptoms. However, these FFM PD counts are of limited clinical use without normative data because it is difficult to determine what a specific score means with regard to the relative level of elevation. The current study presents data from three large normative samples that can be used as norms for the FFM PD counts in the respective countries: United States (N = 1,000), France (N = 801), and Belgium-Netherlands (N = 549). The present study also examines the performance, with regard to diagnostic efficiency, of statistically-defined cut-offs at 1.5 standard deviations above the mean (T > or = 65) versus previously identified cut-offs using receiver-operator characteristics (ROC) analyses. These cut-offs are tested in three clinical samples-one from each of the aforementioned countries. In general, the T > or = 65 cut-offs performed similarly to those identified using ROC analyses and manifested properties relevant to a screening instrument. These normative data allow FFM data to be used in a flexible and comprehensive manner, which may include scoring this type of personality data in order to screen for DSM-IV PD constructs.     

The test-retest reliability of the Form 90-DWI: an instrument for assessing intoxicated driving.

Although driving while intoxicated (DWI) is a pervasive problem, reliable measures of this behavior have been elusive. In the present study, the Form 90, a widely utilized alcohol and substance use instrument, was adapted for measurement of DWI and related behaviors. Levels of reliability for the adapted instrument, the Form 90-DWI, were tested among a university sample of 60 undergraduate students who had consumed alcohol during the past 90 days. The authors administered the instrument once during an intake interview and again, 7-30 days later, to determine levels of test-retest reliability. Overall, the Form 90-DWI demonstrated high levels of reliability for many general drinking and DWI behaviors. Levels of reliability were lower for riding with an intoxicated driver and for variables involving several behavioral conjunctions, such as seat belt use and the presence of passengers when driving with a blood alcohol concentration above .08. Overall, the Form 90-DWI shows promise as a reliable measure of DWI behavior in research on treatment outcome and prevention.     

Personality Characteristics Associated with Persistent ADHD in Late Adolescence

This study focused on the personality characteristics associated with Attention-deficit/Hyperactivity disorder (ADHD) in a longitudinal sample of youth, with a particular focus on differences between those with and without persisting ADHD symptoms. Participants with ADHD (n = 90) were initially evaluated when they were 7–11 years old, and re-assessed at 16–22 years of age. Matched control subjects (n = 80) were recruited at the time of the follow-up evaluation. At follow-up, the Kiddie-SADS-PL, a semi-structured psychiatric interview, and the NEO-PI, a self-report personality inventory, were administered. Data were analyzed using multivariate analyses of variance (MANOVA). Results indicate that childhood ADHD is associated with lower scores on the NEO Conscientiousness subscale in adolescents/young adults—irrespective of the degree of ADHD persistence. In contrast, ratings of Neuroticism and Agreeableness appear to be more closely linked to adolescent status; those with persisting symptoms only exhibited increased Neuroticism and decreased Agreeableness. These results suggest that ADHD, and the degree to which symptoms persist into adolescence, may be closely linked to personality structure.     

The Early Neuropsychological and Behavioral Characteristics of Frontotemporal Dementia

Frontotemporal lobar degeneration (FTLD) represent a constellation of disorders that may be overlooked or misdiagnosed, despite being fairly common presenile neurodegenerative diseases. Although the cognitive disorder can be difficult to document, particularly early in the dementia course, neuropsychological evaluation can assist in the diagnosis. Neuropsychologists are in an excellent position to draw from related disciplines like personality theory and social psychology to better assess the types of changes that characterize the prodromal and early phases of the disease. This review summarizes the current state of the field in the diagnosis of FTLD and discusses the emerging role of neuropsychology in elucidating the brain organization of complex processes including empathy, behavioral control and inhibition, reward systems, appetitive behaviors, emotional regulation, and goal-orientation. As this review underscores, frontotemporal dementia remains a powerful model for studying brain–behavior relationships.
