Declines in cognitive functioning are commonly experienced with aging, yet there is wide variation in the nature and extent of these changes. Previous research has shown associations between the frequency of engaging in stimulating cognitive activities and performance on cognitive tests. However, it is not known whether it is important to increase the amount of cognitive activity as one gets older in order to curtail cognitive declines. We examined cognitive activities and cognition in a national sample of 2,130 community-dwelling middle-aged and older adults from the Midlife in the United States longitudinal study. Participants completed cognitive assessments of episodic memory (EM) and executive functioning (EF) on two occasions, ~9 years apart. At the first assessment, participants ranged in age between 33 and 83 years (M = 55.76, SD = 11.09), with 56.1% women. Multilevel models were tested to examine educational level and change in cognitive activity as predictors of change in EM and EF, controlling for initial level of cognitive activity and key correlates of cognitive decline. Results indicated that increases in cognitive activity were important over and above earlier levels of cognitive activity for reducing declines in EF. Further analysis also showed differential results by educational level. Increased cognitive activity was not associated with changes in EF among individuals with a college degree. In contrast, individuals without a college degree who increased their cognitive activity showed significantly less decline in EF compared to those without a college degree who decreased or maintained their cognitive activity across the 9 years. Thus, the results suggest that increased engagement in cognitive activity makes more of a difference for EF declines among those without a college degree. The results have particular relevance given that aging-related changes in domains such as work status, health, or social relationships can lead to reductions in stimulating cognitive activities. The findings emphasize the importance of increasing cognitive activities especially among those with lower educational attainment.

Abstract Objectives Although educational attainment is related to cognitive function in later life, little is known about the mechanisms involved. This study assessed the independent mediating effects of two behavioral variables, physical and cognitive activity, on the association between educational attainment and cognitive function and change. Methods Data were derived from the three waves of the Midlife in the United States (MIDUS) study. Predictors (educational attainment) were from the 1995 baseline, mediators (physical and cognitive activities) were from the 2004 wave, and outcomes (cognitive function) were from the 2004 and 2013 waves. Conditional process modeling was applied using PROCESS in SPSS. Results There were both direct and indirect effects of educational attainment on level and change of executive function (EF) and episodic memory (EM). Physical activity and cognitive activity were both significant mediators for cognitive level. For mediators of change, however, cognitive activity was significant for EF and physical activity was significant for EM. Discussion Physical and cognitive activity are discussed as possible factors for protecting against cognitive decline in later life. The findings have implications for advancing supportive policies and practices related to maximizing the benefits of education and physical and cognitive activities for cognition in middle age and later life.

This research examined socioeconomic variables, offending behavior, and prior police contact, as predictors of self-reported police contact (questioning or arrest). Utilizing multilevel models and eight waves of National Youth Survey Family Study data, the predictors were examined in a national sample of individuals, over 24 years. Results indicate that police contact is predominately predicted by sex, delinquent peers, and offending behavior. This suggests that several of the variables commonly discussed in police contact literature, including race, are not predictors of police contact at the national level in the United States. Implications of national-level findings on police policy are discussed.

BACKGROUND: Non-motor symptoms have been described in primary dystonia, but the results on cognitive impairment in this condition are discordant. Blepharospasm (BM) is a type of primary focal dystonia characterized by recurrent and involuntary eye blinking. Hemifacial spasm (HS), a condition with different pathophysiology, constitutes an adequate control group when investigating non-motor disturbances in BM. OBJECTIVE:To compare the performance of patients with BM and HS in the Frontal Assessment Battery (FAB). METHOD: Twenty-two patients with BM and 29 patients with HS were submitted to the FAB and the Mini-Mental State Examination (MMSE). FAB scores were compared between the two groups. Correlations between FAB and sociodemographic and clinical variables were calculated. RESULTS: BM group was not different from HS in relation to gender, age, length of symptoms, educational level and performance in the MMSE. FAB scores were also similar in both groups. FAB scores correlated negatively with age and positively with educational level and MMSE scores. CONCLUSION: Executive functioning as assessed by FAB is not altered in BM in comparison with HS.

Abstract Background and Objectives This study explored whether the intensity of cognitive activities could moderate the relationship between a genetic predisposition for developing Alzheimer’s disease (AD) and cognitive functioning among older adults in the United States. Furthermore, we examined whether the same moderating effects were dependent on different measures of cognition. Research Design and Methods We used a data set from the 2000–2014 waves of the Health and Retirement Study and the Consumption and Activities Mail Survey. Our sample included 3,793 individuals aged 50 or older. We used the polygenic score (PGS) for AD as a genetic trait for cognitive functioning. Reading, listening to music, using a computer, playing cards/games/solving puzzles, singing/playing musical instruments, and creating art and crafts were included as cognitive activities, and TV viewing as passive activities. We used total cognition, fluid intelligence, and crystallized intelligence as proxies for cognitive functioning. Growth-curve models were conducted. Results After controlling for covariates, we found that reading books, using a computer, and playing cards/games/solving puzzles had a positive effect on cognitive functioning. An additional hour spent reading books moderated the negative effect of AD PGS on cognition. The measure of fluid, when compared with crystallized intelligence, appeared to drive these results. Discussion and Implications Reading could be a protective factor against cognitive decline among older adults who are genetically predisposed to developing AD. Implications for individuals, caregivers, clinicians, and policymakers are suggested. Furthermore, the onset of AD in those at greater genetic risk may be delayed with this intervention.

Abstract Objective Identifying biomarkers is a priority in translational chronic pain research. Dehydroepiandrosterone (DHEA) and its sulfated form, DHEA-S, are adrenocortical steroids in the blood with neuroprotective properties that also produce sex hormones. They may capture key sex-specific neuroendocrine mechanisms of chronic pain. Design Cross-sectional study. Methods Using data from 1,216 community-dwelling adults aged 34–84 from the Midlife in the United States (MIDUS) cohort, we examined blood DHEA and DHEA-S levels in association with chronic pain in men and women, adjusting for demographics, chronic diseases, medications including opioids, and psychosocial factors. If an association was found, we further explored dose-response relationships by the number of pain locations and the degree of pain interference. Results In women, chronic pain was associated with 0.072 lower (95% confidence interval [CI], –0.127 to –0.017) log10 DHEA-S µg/dL, with pain in one to two locations associated with 0.068 lower (95% CI, –0.131 to –0.006) and in three or more locations 0.071 lower (95% CI, –0.148 to 0.007) log10 DHEA-S (P for trend = 0.074). Furthermore for women, low-interference pain was associated with 0.062 lower (95% CI, –0.125 to –0.000), whereas high-interference pain was associated with 0.138 lower (95% CI, –0.233 to –0.043) log10 DHEA-S (P for trend = 0.004). Chronic pain was not associated with DHEA or DHEA-S levels in men or DHEA levels in women. Conclusions Chronic pain and its functional interference correspond to lower blood DHEA-S levels in women.

Abstract. The positive effects of goal setting on motivation and performance are among the most established findings of industrial–organizational psychology. Accordingly, goal setting is a common management technique. Lately, however, potential negative effects of goal-setting, for example, on unethical behavior, are increasingly being discussed. This research replicates and extends a laboratory experiment conducted in the United States. In one of three goal conditions (do-your-best goals, consistently high goals, increasingly high goals), 101 participants worked on a search task in five rounds. Half of them (transparency yes/no) were informed at the outset about goal development. We did not find the expected effects on unethical behavior but medium-to-large effects on subjective variables: Perceived fairness of goals and goal commitment were least favorable in the increasing-goal condition, particularly in later goal rounds. Results indicate that when designing goal-setting interventions, organizations may consider potential undesirable long-term effects.

Summary: In the United States' normative population for the WAIS-R, differences (Ds) between persons' verbal and performance IQs (VIQs and PIQs) tend to increase with an increase in full scale IQs (FSIQs). This suggests that norm-referenced interpretations of Ds should take FSIQs into account. Two new graphs are presented to facilitate this type of interpretation. One of these graphs estimates the mean of absolute values of D (called typical D) at each FSIQ level of the US normative population. The other graph estimates the absolute value of D that is exceeded only 5% of the time (called abnormal D) at each FSIQ level of this population. A graph for the identification of conventional “statistically significant Ds” (also called “reliable Ds”) is also presented. A reliable D is defined in the context of classical true score theory as an absolute D that is unlikely (p < .05) to be exceeded by a person whose true VIQ and PIQ are equal. As conventionally defined reliable Ds do not depend on the FSIQ. The graphs of typical and abnormal Ds are based on quadratic models of the relation of sizes of Ds to FSIQs. These models are generalizations of models described in Hsu (1996) . The new graphical method of identifying Abnormal Ds is compared to the conventional Payne-Jones method of identifying these Ds. Implications of the three juxtaposed graphs for the interpretation of VIQ-PIQ differences are discussed.

Scholarly and public debates about criminal appeals have largely taken place in an empirical vacuum. This study builds on our prior empirical work exploring defense-initiated criminal appeals and focuses on criminal appeals by state and federal prosecutors. Exploiting data drawn from a recently released national sample of appeals by state prosecutors decided in 2010, as well as data from all appeals by federal prosecutors to the United States Court of Appeals terminated in the years 2011 through 2016, we provide a detailed snapshot of non-capital, direct appeals by prosecutors, including extensive information on crime type, claims raised, type of defense representation, oral argument and opinion type, as well judicial selection, merits review, and relief. Findings include a rate of success for state prosecutor appeals about four times greater than that for defense appeals (roughly 40% of appeals filed compared to 10%). The likelihood of success for state prosecutor-appellants appeared unrelated to the type of crime, claim, or defense counsel, whether review was mandatory or discretionary, or whether the appellate bench was selected by election rather than appointment. State high courts, unlike intermediate courts, did not decide these appeals under conditions of drastic asymmetry. Of discretionary criminal appeals reviewed on the merits by state high courts, 41% were prosecutor appeals. In federal courts, prosecutors voluntarily dismissed more than half the appeals they filed, but were significantly less likely to withdraw appeals from judgments of acquittal and new trial orders after the verdict than to withdraw appeals challenging other orders. Among appeals decided on the merits, federal prosecutors were significantly more likely to lose when facing a federal defender as an adversary compared to a CJA panel attorney.

OBJECTIVETraumatic brain injury (TBI) is a leading cause of morbidity and mortality in the US, but the true incidence of TBI is unknown.METHODSThe National Trauma Data Bank National Sample Program (NTDB NSP) was queried for 2007 and 2013, and population-based weighted estimates of TBI-related emergency department (ED) visits, hospitalizations, and deaths were calculated. These data were compared to the 2017 Centers for Disease Control and Prevention (CDC) report on TBI, which used the Healthcare Cost and Utilization Project’s National (“Nationwide” before 2012) Inpatient Sample and National Emergency Department Sample.RESULTSIn the NTDB NSP the incidence of TBI-related ED visits was 59/100,000 in 2007 and 62/100,000 in 2013. However, in the CDC report there were 534/100,000 in 2007 and 787/100,000 in 2013. The CDC estimate for ED visits was 805% higher in 2007 and 1169% higher in 2013. In the NTDB NSP, the incidence of TBI-related deaths was 5/100,000 in 2007 and 4/100,000 in 2013. In the CDC report, the incidence was 18/100,000 in both years. The CDC estimate for deaths was 260% higher in 2007 and 325% higher in 2013.CONCLUSIONSThe databases disagreed widely in their weighted estimates of TBI incidence: CDC estimates were consistently higher than NTDB NSP estimates, by an average of 448%. Although such a discrepancy may be intuitive, this is the first study to quantify the magnitude of disagreement between these databases. Given that research, funding, and policy decisions are made based on these estimates, there is a need for a more accurate estimate of the true national incidence of TBI.
