Speaking is one of the most complex motor actions that humans can perform, requiring the coordination between linguistic, cognitive, affective and sensorimotor systems. Perhaps counterintuitively, it is also one of the easiest acts that humans perform, on a daily basis, from a very early age till the end of life, without even thinking about it. With age, however, spoken language production undergoes significant changes, with potential impacts on interpersonal communication and social participation. Unfortunately, the neurobiological mechanisms involved are unclear, which impedes efforts towards the development of clinical interventions, differential diagnosis strategies and even prevention strategies for this population. In the present study, we examined age differences in speech production using a simple diadochokinetic rates task in which phonological and sequential complexity were manipulated. 85 cognitively healthy adults (20-93 years) were recruited from the general population. Cognitive level, hearing and depression symptoms were measured. Participants produced short and long sequences of simple and complex syllables aloud as quickly, steadily and accurately as possible. Performance was assessed in terms of articulation rate, articulation rate stability and accuracy. Results show that, controlling for cognition, hearing and depression, articulation rate stability and accuracy declined significantly with age. The phonological manipulation had more impact on performance than the sequential manipulation. These findings were interpreted as reflecting age-related central disruptions at the level of phonological and motor planning, which provides important new cues into underlying neurobiological mechanisms.

Life balance is associated to health, well-being and quality of life and is a target of psychiatric rehabilitation interventions. However, little is known about this life dimension in women living with personality disorders. The purpose of this descriptive-correlational study was to compare and explore relationships between subjective life balance, objective time use, quality of life and perceived stress in women without a mental health disorder (n = 43) and women with a personality disorder (clusters B and C) (n = 30), aged between 18 and 50 years old. The variables were measured with the Life Balance Inventory (subjective life balance), the Occupational Questionnaire (objective time use), the Depression Anxiety Stress Scale (perceived stress) and the Quality of Life Index (satisfaction and importance with life domains). The analyses showed that women with a personality disorder spend significantly less time in work but more time in daily tasks and leisure. Subjective life balance, quality of life and perceived stress were significantly lower in women with a personality disorder (p < 0.05). In women with a personality disorder, subjective life balance was explained by quality of life (R = 27.5 %). In women without a mental illness, subjective life balance was explained by quality of life and motherhood (R = 36.1 %). To support the recovery of women with personality disorders and their quality of life, it is important to address objective and subjective time use to enable accomplishment of a variety of meaningful activities.

Date Presented 4/17/2015 Little is known about the life balance of women with Clusters B and C personality disorders. This study compared subjective and objective life balance in women with and without personality disorders. It also examined relationships among subjective and objective life balance, stress, and quality of life.
