Perceptual inhibition associated with sensory integration for balance in older adults. Table 3. Curr. This is a planned secondary analysis of a cohort study conducted between July and December 2012 on stepping, cognition and falls in 212 independently living older adults in Sydney, Australia (Schoene et al., 2017). 11:133. doi: 10.3389/fnagi.2019.00133.

The aging brain undergoes physical and functional changes including a decline in processing speed, central sensory functioning, white matter integrity, and brain volume. Physiol. Behav. 53, 1618–1622. Our findings suggest the incorporation of implicit learning tasks in interventions for older people may be beneficial to improve balance and reduce fall risk. Between- and within-individual effects of visual contrast sensitivity on perceptual matching, processing speed, and associative memory in older adults. Cogn. Gerontology 47, 189–194. 14:107. doi: 10.1186/1471-2318-14-107, Sherrington, C., Michaleff, Z. Soc. (2013). It is important to remember however, that there are a very wide range of causes of disability: some individuals may have high physical health and healthcare needs, and others may experience a very high standard of physical health. [32] This increase in blood flow is potentially related to the evidence that atrophy heightens blood flow and metabolism, which is measured as the BOLD response, or blood-oxygen-level dependence, with fMRI. Research has suggested that cognitive flexibility is related to other cognitive abilities, such as fluid intelligence, reading fluency, and reading comprehension. Regardless of the specificity of the definition, researchers have generally agreed that cognitive flexibility is a component of executive functioning, higher-order cognition involving the ability to control one's thinking. Fitness is the condition of being physically fit and healthy and involves attributes that include, but are not limited to mental acuity, cardiorespiratory endurance, muscular strength, muscular endurance, body composition, and flexibility. Aging 34, 1133–1144. 17, 27–35. We have also shown that slow inhibitory choice stepping reaction time (iCSRT), a test of combined inhibition and rapid step initiation, was predictive of falls in older people and that this association was not mediated by body sway, processing speed or attention (Schoene et al., 2017). [17][19], In the Multiple Classification Card Sorting Task, children are shown cards and asked to sort them based on two different dimensions (e.g. J. Clin. Obtaining insights into these processes would increase our understanding of the complex inter-relationships between cognitive and motor functions and their impact on falls. Consistent with previous findings, those with poor balance were older and performed worse in tests of contrast sensitivity, proprioception and hand reaction time than those with good balance (Lord and Ward, 1994). It is calculated by subtracting the mean RT of all congruent flanking conditions, summed across cue types, from the mean RT of incongruent flanking conditions (Fan et al., 2002). Perceptual inhibition is associated with sensory integration in standing postural control among older adults. J. de Boer, M. R., Pluijm, S. M., Lips, P., Moll, A. C., Volker-Dieben, H. J., Deeg, D. J., et al. J. Gen. Intern. What does 10 L I mean? Notice from this description that psychological flexibility does not prescribe one’s attempts to escape or avoid their most painful experiences but instead is an invitation to experience them with an aim to live a meaningful life. These findings suggest that poor mental flexibility affects the ability to maintain steady balance contributing to increased risk of falls in older people. Regions associated with cognitive flexibility such as the PFC and PC atrophy, or shrink, with age, but also show greater task-related activation in older individuals when compared to younger individuals. The relevance of situation awareness in older adults’ cognitive functioning: a review. While most research has examined aerobic training (Ludyga et al., 2016), findings from one study suggest a positive effect of resistance training on cognitive outcomes in older adults (Liu-Ambrose et al., 2012). The unity and diversity of executive functions and their contributions to complex “Frontal Lobe” tasks: a latent variable analysis. Redfern, M. S., Chambers, A. J., Sparto, P. J., Furman, J. M., and Jennings, J. R. (2018). Our findings may indicate fallers have poorer executive function in general, rather than specific mental flexibility deficits confirming results from cognitive and brain-imaging studies that demonstrate executive functions, including mental flexibility reflect some common, and distinct components (Miyake et al., 2000; Wager et al., 2005). Figure 1. doi: 10.1016/j.gaitpost.2010.11.011. Visual impairment and falls in older adults: the Blue Mountains Eye Study. Impaired executive functions, especially inhibition, have been identified as risk factors for falls in several studies. doi: 10.3758/s13428-011-0096-6, Plummer-D’Amato, P., Altmann, L. J., and Reilly, K. (2011). Latent structure of the Wisconsin Card Sorting Test in a clinical sample. Healthy mind in healthy body? doi: 10.1016/s0966-6362(01)00134-5, Verbaken, J. H., and Johnston, A. W. (1986). 42, 345–346. The objective of the current study, therefore, was to investigate the importance of more complex mental flexibility components to balance control and falls in older people and their role as potential confounders and moderators in the association between poor balance and falls. Exploring the nature of cognitive flexibility. Bone Miner. Cognitive flexibility, or mental flexibility, is the important ability to switch between tasks and adapt to a changing situation quickly and efficiently. 92, 947–953. J. Other terms for and components of cognitive flexibility include mental flexibility, mental set shifting, cognitive shifting, task switching/shifting, and attention switching/shifting. This study found significant associations between cognitive functioning, balance and falls in older people without major cognitive impairments. Be open-minded. [6] Thus, when an individual is better able to suppress aspects of a stimulus to focus on more important aspects (i.e. For no-go trials (33% of trials), signaled by an arrow on the screen changing from white to purple, participants had to suppress the prepotent stepping response. Further, lower concept formation ability partly explained the association between balance and falls: i.e., fallers in the upper balance tertile had reduced concept formation performance whereas non-fallers had similar concept formation performance across the three balance tertiles. This confounding was driven by notably poorer concept formation performance in the fallers and no corresponding reduction in the non-fallers within the poor balance group (Figure 1). [29] Potential treatments may lie in neurochemical modulation. For example, when individuals are better able to shift their thinking from situation to situation they will focus less on stressors within these situations.[15]. Components of postural dyscontrol in the elderly: a review. In this test, participants matched stimulus cards according to a rule (color, shape, or number) without being informed of the rule. 22, 262–272. The basic score on each card is the total time (in seconds) that the participant takes to respond verbally. Med. Cognitive flexibility (also referred to as “shifting”) refers to our ability to switch between different mental sets, tasks, or strategies (Diamond, 2013; Miyake & Friedman, 2012). Med. Contrast sensitivity but not visual acuity is associated with gait in older adults. Thus, research suggests if an individual is centrated in their thinking, then they will be more cognitively inflexible. At this time, this does not apply to the term Mental Strength. Examination of age-related deficits on the Wisconsin Card Sorting Test. Computerized cognitive training with older adults: a systematic review. If calendars were not returned, follow-up phone calls were made within 14 days of end of each month to remind participants to send back their calendars and to obtain additional information on falls. Here, it is defined as a construct composed of multiple cognitive processes that work together to adjust the course of thoughts or actions according to the changing demands of a situation without the use of explicit instructions (Berg, 1948). (2013). A Biol. both color and kind of object). 65, 1338–1343. However, the role of mental flexibility in balance in older people remains unclear. Lord, S. R., and Fitzpatrick, R. C. (2001). Sports Med. Osteoporos. Our study confirms previous findings that balance is associated with higher order cognitive functions and shows older people with both impaired balance and reduced mental flexibility are at a substantially increased risk of falling. The "color card" displays patches of different colors, which participants are asked to identify as quickly as possible. Sci. Table 4. The rate of commission errors during the iCSRT task would have been a more genuine reflection of inhibition. Participants were recruited via a research institute’s volunteer database and from residents of a retirement village in Sydney, Australia. doi: 10.1093/gerona/glx021, Fan, J., Mccandliss, B. D., Sommer, T., Raz, A., and Posner, M. I. This is not surprising as balance depends on multiple sensory, motor, and cognitive functions. Several online programs marketed to those seeking to increase cognitive ability have been created to enhance "brain fitness", including cognitive flexibility. Applications for teacher education have involved teacher-training sessions based on video instruction, whereby novice teachers viewed footage of master teachers conducting a literacy workshop. The most widely used example of hypertext is the Internet, which dynamically presents information in terms of interconnection (e.g. Panel (A) shows a decline in concept formation performance across sway tertiles; Panel (B) shows the additional impact of faller status. Aging Phys. A response switch would require different response mapping, such as circle right button and square left button and vice versa. Emotional flexibility, a component of psychological flexibility, is typically acknowledged to encompass the capacity to Brespond flexibility to changing emotional circumstances^ (Waughetal. The final card type is the "color-word card", which displays the names of the colors printed in an ink of a conflicting color (e.g. Attention influences sensory integration for postural control in older adults. The "word card," displays the names of colors printed in black and white ink, which participants are again asked name as quickly as possible. Juveniles with Anorexia nervosa have marked decreases in set-shifting abilities, possibly associated with incomplete maturation of prefrontal cortices associated with malnutrition. Gregory, M. A., Gill, D. P., and Petrella, R. J. BT, DS, FP-F, SL, and WK analyzed the data. Sci. Seated cognitive training can also improve motor functions (Verghese et al., 2010; Milman et al., 2014; Smith-Ray et al., 2015), and videogames and virtual reality interventions with high attentional switching demands may contribute to improved mental flexibility (Canty et al., 2014; Cardoso-Leite and Bavelier, 2014), as well as balance control in older adults (Schoene et al., 2014). Finally, when ANT executive network performance and iCSRT_RT were entered into the model, balance status (tertile 3), concept formation, contrast sensitivity and iCSRT_RT remained significant predictors of falls status (model 4, Table 4), with no evidence of an effect modification by balance status × concept formation (p = 0.250). Effect of cognitive remediation on gait in sedentary seniors. Sci. doi: 10.1016/j.neurobiolaging.2011.05.010, Lord, S. R., Clark, R. D., and Webster, I. W. (1991). 23, 2409–2424. Behavioral inhibition, sustained attention, and executive functions: constructing a unifying theory of ADHD. Mental flexibility is important to shift mental sets to adjust behaviors quickly, e.g., when (unpredictable) environmental demands require proactive and/or reactive responses to avoid a loss of balance. Soc. Risk factors for falls in community-dwelling older people: a systematic review and meta-analysis. doi: 10.1016/j.jclinepi.2004.10.018, Haaland, K. Y., Vranes, L. F., Goodwin, J. S., and Garry, P. J. [1] Cognitive flexibility is usually described as one of the executive functions. Researchers in the field advocate a teaching style that incorporates group problem-solving activities and demands higher-level thought. Mental flexibility is a component of the executive function and comprises multiple cognitive processes that work together to adjust the course of thoughts or actions according to the changing demands of a situation without the use of explicit instructions. Flexibility in your convictions or thoughts isn’t the Negative binomial regression analysis revealed that balance status (sway tertiles) was associated with an increased rate of falls. Some cognitive functions, especially executive functioning have been shown to affect balance and discriminate fallers from non-fallers. Sci. Testing the efficiency and independence of attentional networks. doi: 10.1093/gerona/glr019, Duggan, E., Donoghue, O., Kenny, R. A., Cronin, H., Loughman, J., and Finucane, C. (2017). J. Optom. Sci. Particularly, in individuals with poor balance, worse mental flexibility was associated with more falls, further confirming our second hypothesis. Individuals with reduced balance control also performed worse in the computerized short version of the WCST, a test of mental flexibility, mainly due to poor concept formation. Further analyses demonstrated that this conceptual ability impairment statistically confounded the association between balance status and falls. Age Ageing 23, 452–460. Dual-task effects of spontaneous speech and executive function on gait in aging: exaggerated effects in slow walkers. In related research conducted with nursing home residents, more than 50% of falls were due to incorrect weight shifting and poor obstacle negotiation (Robinovitch et al., 2013). Geriatr. its a mental flexibility quiz ... ... .. the quality of being easily adapted or of offering many different options: This blogging platform is becoming more and more popular because of its flexibility, power, and simplicity. However, response selection and response inhibition should not be separated as they are linked with each other in that first the automatic response is inhibited to enable a switch to the controlled response selection (Mostofsky and Simmonds, 2008). hyperlinks). doi: 10.1037/a0015389, Ashendorf, L., and McCaffrey, R. J. As noted above, heritability is specific Unadjusted and adjusted models for the association between balance status and fall rates with 95% confidence intervals. 29, 198–214. 51, 1750–1758.

Hypertext documents, therefore, include nodes â bits of information â and links, the pathways between these nodes. Population norms for edge contrast sensitivity. Bonferroni-adjusted pairwise comparisons showed the poor balance group required more trials than the good balance group (p = 0.003) (Table 3). A Biol. 58, 595–602. A Biol. Med. A WCST short form (64 trials) was computer-administered using a freely available and validated software tool [The Psychology Experiment Building Language (PEBL), version 0.141] (Piper et al., 2012; Fox et al., 2013). Sway path in millimeters was measured with a sway-meter that measured displacements of the body at the level of the waist. 121, 65–94. Sci. This is reflected in the integration of cognitive flexibility into educational policy regarding academic guidelines and expectations. We need to acknowledge some limitations. 64, 569–576. Psychol. This task appears to be more difficult as research has shown that seven-year-old children were incapable of sorting cards based on the two dimensions simultaneously. This work was supported by an International Postgraduate Research Scholarship (DS) and a NHMRC Senior Principal Research Fellowship (SL). J. Indeed, findings from the current study demonstrate that non-fallers react faster in a complex stepping task (Schoene et al., 2017). Stance and target panels were displayed on the screen. [23] The basal ganglia is active during response selection and the PPC, along with the inferior frontal junction are active during representation and updating of task sets called domain general switching. Second, all tests were done in one single session and it cannot be ruled out that fatigue played a role. 4, 3–13. Disord. Further studies could include real life simulations to examine how poor concept formation is related to the process of falling. The mean number of falls for the good balance group was 0.65 (SD 1.17), for the fair balance group 1.01 (1.63) and for the poor balance group 1.74 (SD 3.92). doi: 10.1016/j.jamda.2017.03.010, Schoene, D., Lord, S.

People were excluded if they were cognitively impaired [diagnosis of neurodegenerative disease, Rapid Dementia Screening Test ≤4 (Kalbe et al., 2003)], had movement disorders (self-reported) or limiting lower limb pain and visual impairments that could not be corrected [>6/16 on a LogMAR visual acuity chart, color-blind]. Findings from a 12 week pilot study. (2009) found subtle differences in inhibition are an early marker of increased fall risk, while multiple cognitive domains are impaired in recurrent fallers. However, cognitive flexibility refers to the ability to adapt to a change, while mental shifting is the process that makes it possible to adapt to the change. 24,238–265.
