AbstractDesign Fluency (DF) is typically assumed to assess planning, cognitive flexibility, and fluency in generation of visual patterns, above and beyond contributions from motor speed (Delis, Kaplan, & Kramer, 2001; Ruff, 1998). The present study examined these assumptions, as little construct validation research has been done in the past. Sixty one community-dwelling elderly participants were administered the DF, Trail Making, and Letter Fluency tests from the Delis-Kaplan Executive Function System (D-KEFS), as well as electronically administered measures of motor planning and motor sequence fluency. Hierarchical regressions were used to parse out unique variance contributions to DF performance. The results showed that generation of novel designs (i.e., the first two trials on the D-KEFS DF) relied primarily on motor planning, the ability to generate novel motor actions, and, to a lesser extent, speed of drawing with a writing implement. In contrast, generation of unique designs while switching (i.e., the third trial on the D-KEFS DF) relied primarily on visual scanning and perhaps visual-attentional resources. These findings highlight the wisdom of interpreting the switching trial of the D-KEFS DF separately. Interestingly, cognitive flexibility did not contribute to performance on any of the three D-KEFS DF trials. (JINS, 2010, 16, 26–37.)

Abstract Objective ApoE is a well-known gene carrying risk for Alzheimer’s disease and is associated with memory performance while the COMT gene is associated with executive functioning but is understudied. The present study investigated these gene interactions across cognitive domains. Method A larger study on gait and aging recruited 89 healthy community-dwelling adults over the age of 60. The primary analyses included 82 participants (67% female, mean age = 74.61, SD = 6.71). The analyses on executive functioning included 72 participants (65% female, mean age = 73.02, SD = 4.99) who completed all measures of interest. ApoE status was defined as presence/absence of Ɛ4. The rs4680 gene on the COMT allele was classified into Val/Met, Val/Val, and Met/Met genotypes. Biological sex was included as a binary term (i.e., male/female). Index variables and age corrected standard scores on the Repeatable Battery for the Assessment of Neuropsychological Status, verbal fluency, and Trail Making Test were included. Results Gene–gene interactions were found for overall cognitive functioning, immediate memory, and semantic fluency. There were main effects of sex for overall cognitive functioning, immediate memory, delayed memory, and semantic fluency. There were main effects for COMT for delayed memory and a main effect for both COMT and ApoE for visuospatial functioning, coding, and verbal fluency (all p’s < 0.05). There were no ApoE x COMT x Sex interactions and Trail Making Test B was not related to either gene or sex. Conclusion(s) Our findings suggest that both COMT and ApoE (and their interaction) influence cognition. Future research should investigate gene–gene interactions in larger samples with more comprehensive cognitive batteries.

Successful Behavior

Executive functions (EF) represent higher order top-down mechanisms regulating information processing. While suboptimal EF have been studied in various patient groups, their impact on successful behavior is still not well described. Previously, it has been suggested that design fluency (DF)—a test including several simultaneous EF components mainly related to fluency, cognitive flexibility, and creativity—predicts successful behavior in a quickly changing environment where fast and dynamic adaptions are required, such as ball sports. We hypothesized that similar behaviors are of importance in the selection process of elite police force applicants. To test this hypothesis, we compared elite police force applicants (n = 45) with a control group of police officer trainees (n = 30). Although both groups were better than the norm, the elite police force applicants had a significantly better performance in DF total correct when adjusting for sex and age [F(1,71) = 18.98, p < 0.001]. To understand how this capacity was altered by stress and tiredness, we re-tested the elite police force applicants several days during an extreme field assessment lasting 10 days. The results suggested that there was a lower than expected improvement in DF total correct and a decline in the DF3-subtest that includes a larger component of cognitive flexibility than the other subtests (DF1 and DF2). Although there was a positive correlation between the baseline session and the re-test in DF3 [r(40) = 0.49, p = 0.001], the applicants having the highest scores in the baseline test also displayed the largest percentage decline in the re-test [r(40) = −0.46, p = 0.003]. In conclusion, our result suggests that higher order EF (HEF) that include cognitive flexibility and creativity are of importance in the application for becoming an elite police officer but relatively compromised in a stressful situation. Moreover, as the decline is different between the individuals, the results suggest that applicants should be tested during baseline conditions and during stressful conditions to describe their cognitive capacity fully.

Abstract The relationship between older adults’ gait and cognition has been well-studied, however there is little consensus regarding a best set of measures to assess cognition. One option that has not been previously examined is the NIH Toolbox Cognition Battery (NIHT-CB), which was developed to be used across the lifespan and across research disciplines. This study examined the relationships between the seven subtests of the NIHT-CB, Trail-Making Tests A and B, and temporospatial measures of gait. One hundred sixty-seven healthy, community-dwelling older adults (115 females, 73.4 ± 4.5 years) completed these cognitive measures and also walked at their self-selected pace back-and-forth five times along a temporospatial-measuring walkway. The mean and coefficient of variation were calculated for each gait variable (stride length, width, time and velocity; stance/swing time and % of stride). After controlling for potential confounders (height, weight, age, sex, education, self-efficacy, health, exercise and falls history), executive function measures were typically the most significant cognitive predictors. More specifically, the Dimensional Change Card Sort task was the best predictor of temporal measures and stride velocity (all ps < 0.001) and the Trail-Making Test Part B was the best predictor for variability measures (five of eight p-values < 0.001). Interestingly, stride length and also stance and swing % of stride were strongly related to a measure of language - Picture Vocabulary (all ps < 0.006). The NIHT-CB appears to be a useful tool for studies of gait in older adults, particularly when used in conjunction with Trail-Making Test B.

ABSTRACT Objectives: (1) To delineate whether cognitive flexibility and inhibitory ability are neurocognitive markers of passive suicidal ideation (PSI), an early stage of suicide risk in depression and (2) to determine whether PSI is associated with volumetric differences in regions of the prefrontal cortex (PFC) in middle-aged and older adults with depression. Design: Cross-sectional study. Setting: University medical school. Participants: Forty community-dwelling middle-aged and older adults with depression from a larger study of depression and anxiety (NIMH R01 MH091342-05 PI: O’Hara). Measurements: Psychiatric measures were assessed for the presence of a DSM-5 depressive disorder and PSI. A neurocognitive battery assessed cognitive flexibility, inhibitory ability, as well as other neurocognitive domains. Results: The PSI group (n = 18) performed significantly worse on cognitive flexibility and inhibitory ability, but not on other neurocognitive tasks, compared to the group without PSI (n = 22). The group with PSI had larger left mid-frontal gyri (MFG) than the no-PSI group. There was no association between cognitive flexibility/inhibitory ability and left MFG volume. Conclusions: Findings implicate a neurocognitive signature of PSI: poorer cognitive flexibility and poor inhibitory ability not better accounted for by other domains of cognitive dysfunction and not associated with volumetric differences in the left MFG. This suggests that there are two specific but independent risk factors of PSI in middle- and older-aged adults.

Stuttering is a neurodevelopmental disorder characterized by impaired execution of articulatory movements needed for fluent speech production. Existing theoretical models propose that these deficits reflect a malfunction in the cortico-basal-ganglia-thalamocortical (cortico-BG) loop that is responsible for selecting and initiating speech motor programs. However, the cortico-BG loop has also been hypothesized to play a role in speech motor learning. To distinguish motor execution impairments from motor learning impairments in stuttering, the authors examined the behavioral and neural correlates of learning to produce novel phoneme sequences in adults who stutter (AWS) and neurotypical controls. Participants intensively practiced producing pseudowords containing non-native consonant clusters over two days. Results showed that, behaviorally, both AWS and controls produced the words with increased speed and accuracy following motor practice, and the rate of improvement was comparable for the two groups. Using functional magnetic resonance imaging (fMRI), the authors compared brain activity during articulation of the practiced words and a set of novel pseudowords (matched in phonetic complexity). FMRI analyses revealed no differences between AWS and controls in cortical or subcortical regions; both groups showed comparable increases in activation in left-lateralized brain areas implicated in phonological working memory and speech motor planning during production of the novel sequences compared to the practiced sequences. Moreover, activation in left-lateralized basal ganglia sites was negatively correlated with stuttering severity in AWS. Collectively, these findings indicate that AWS exhibit no deficit in learning novel speech sequences but do show impaired execution of these sequences prior to and after learning.

During navigation, animals often use recognition of familiar environmental contexts to guide motor action selection. The retrosplenial cortex (RSC) receives inputs from both visual cortex and subcortical regions required for spatial memory and projects to motor planning regions. However, it is not known whether RSC is important for associating familiar environmental contexts with specific motor actions. We test this possibility by developing a task in which motor trajectories are chosen based on the context. We find that mice exhibit differential predecision activity in RSC and that optogenetic suppression of RSC activity impairs task performance. Individual RSC neurons encode a range of task variables, often multiplexed with distinct temporal profiles. However, the responses are spatiotemporally organized, with task variables represented along a posterior-to-anterior gradient along RSC during the behavioral performance, consistent with histological characterization. These results reveal an anatomically organized retrosplenial cortical circuit for associating environmental contexts with appropriate motor outputs.
