Behavioral Measures

There are substantial declines in behavioral measures of cognitive function with age, including decreased function of executive processes and long-term memory. There is also evidence that, with age, there is a decrease in brain volume, particularly in the frontal cortex. When young and older adults perform cognitive tasks that depend heavily on frontal function, neuroimaging evidence indicates that older adults recruit additional brain regions in order to perform the tasks. This additional neural recruitment is termed "dedifferentiation," and can take multiple forms. This recruitment of additional neural tissue with age to perform cognitive tasks was not reflected in the behavioral literature, and suggests that there is more plasticity in the ability to organize brain function than was previously suspected. We review both behavioral and neuroscience perspectives on cognitive aging, and then connect the findings in the two areas. From this integration, we suggest important unresolved questions and directions for future research.

Abstract We identify the significance and typical requirements of developmental analyses of the microbiome-gut-brain (MGB) in parents, offspring, and parent-offspring relations, which have particular importance for neurobehavioral outcomes in mammalian species, including humans. We call for a focus on behavioral measures of social-emotional function. Methodological approaches to interpreting relations between the microbiota and behavior are discussed.

Purpose The purpose of this study was to assess the perceptions of stuttering of school-age children who stutter and those of adults who stutter through the use of the same tools that could be commonly used by clinicians. Method Twenty-three participants across various ages and stuttering severity were administered both the Stuttering Severity Instrument–Fourth Edition (SSI-4; Riley, 2009 ) and the Wright & Ayre Stuttering Self-Rating Profile ( Wright & Ayre, 2000 ). Comparisons were made between severity of behavioral measures of stuttering made by the SSI-4 and by age (child/adult). Results Significant differences were obtained for the age comparison but not for the severity comparison. Results are explained in terms of the correlation between severity equivalents of the SSI-4 and the Wright & Ayre Stuttering Self-Rating Profile scores, with clinical implications justifying multi-aspect assessment. Conclusions Clinical implications indicate that self-perception and impact of stuttering must not be assumed and should be evaluated for individual participants. Research implications include further study with a larger subject pool and various levels of stuttering severity.

To investigate the effects of leisure activities on cognitive performance of healthy older subjects, an innovative intervention program was developed. Frequent participation in cognitively stimulating activities (i.e., reading, playing chess, or playing music) is associated with reduced risk of dementia. AKTIVA (active cognitive stimulation – prevention in the elderly) is an intervention program designed to enhance cognitive stimulation in everyday life by increasing cognitive stimulating leisure activities. The present study determines the effects of AKTIVA on cognitive function, mood and attitude toward aging in a sample of older participants from the general population. Several measurement instruments were used including the Alzheimer’s Disease Assessment Scale (ADAS-Cog), the Trail-Making Test (TMT), and the Memory Complaint Questionnaire (MAC-Q). Initially, the sample consisted of 307 older persons (170 female, 72 ± 7 years). The intervention was evaluated with a randomized, controlled pre-post follow-up design. Participants were randomly assigned to one of three conditions: AKTIVA intervention (n = 126), AKTIVA intervention plus nutrition and exercise counseling (n = 84), no-intervention control group (n = 97). The AKTIVA intervention consisted of 8 weekly sessions and two booster sessions after a break of 4 months. Participation in the group program resulted in positive effects on cognitive function and attitude toward aging for subassembly groups. Older persons (≥ 75 years) showed enhanced speed of information processing (by TMT Version A) (F = 4.17*, p < .05); younger participants (< 75 years) showed an improvement in subjective memory decline (by MAC-Q) (F = 2.55*, p < .05). Additionally, AKTIVA enhanced the frequency of activities for leisure activities for subassembly groups. The results of this study suggest that the AKTIVA program can be used to increase cognitively stimulating leisure activities in the elderly. Further research is necessary to identify the long-term effects of this intervention particularly with respect to the prevention of dementia.
