Effect of emotional valence on true and false recognition controlling arousal.

The aim of our experiment was to analyse the effect of the emotional valence (positive, negative, or neutral) on true and false recognition, matching the arousal, frequency, concreteness, and associative strength of the study and recognition words. Fifty younger adults and 46 healthy older adults performed three study tasks (with words of different valence: positive, negative, neutral) and their corresponding recognition tests. Two weeks later, they performed the three recognition tests again. The results show that words with a negative valence produced less true recognition and less false recognition than words with a positive or neutral valence, in both younger and older adults, on the immediate recognition test. This pattern of results was also found in the younger adults on the delayed recognition test, whereas in the older participants, these differences disappeared. Thus, when arousal is controlled, both younger and older adults tend to recognise negative information worse than positive or neutral information, but they also commit fewer errors. Results would suggest that the greater arousal commonly associated with negative stimuli, rather than their own valence, could explain some of the contradictory results found in the literature.

Coping and guilt in informal caregivers: a predictive model based on structural equations.

Caregivers experience great stress, and coping can be one of the factors, which determine the extent of stress. The aim of the present paper is to analyze the effects of coping strategies on distress of the older adult's caregiver, including guilt as a mediating factor in those maladaptive strategies. The sample consisted of 201 informal caregivers of institutionalized older adults. The three constructs measured were: stress, guilt, and coping strategies. Results showed that strategies that have a better ability to reduce stress are active, positive reframing and acceptance; on the contrary, behavioral disengagement, self-distraction, self-blame and venting positively predicted the feeling of guilt that facilitated the perception of stress. Given the important association obtained between the experience of guilt and psychological distress in caregivers, it could be relevant to develop psychoeducational interventions with caregivers including techniques to reduce this feeling of guilt and develop cognitive behavioral strategies that facilitate adaptation.

Conflict monitoring on an emotional Stroop task. Comparison of healthy older adults and patients with major neurocognitive disorders due to probable AD.

INTRODUCTION: The conflict monitoring system exerts an influence on centers responsible for cognitive control, causing them to intervene more strongly in processing when conflict occurs. These mechanisms are usually investigated through specific tasks where there is an inherent interference elicited by the congruency or incongruency between the stimuli and responses, such as the Stroop task. In studies of emotional conflict, one hypothesis related to the dorsal anterior cingulate cortex (ACC) is that it serves, in part, to signal the appearance of conflicts, thus triggering compensatory adjustments. This study aims to verify whether the conflict monitoring hypothesis is confirmed in a group with Alzheimer's disease and, therefore, whether they exhibit a reduction in their reaction times. METHOD: A group of healthy older adults (HOA) and a group with Major Neurocognitive Disorders due to probable AD were evaluated to test the conflict monitoring hypothesis with an emotional Stroop task. RESULTS: A significant interaction was obtained on the word and faces blocks. In the HOA group, a reduction in reaction times was observed, whereas in the AD groups, no reduction in reaction times was obtained. CONCLUSIONS: Whereas in HOA the conflict monitoring hypothesis is confirmed, in the Major Neurocognitive Disorders due to probable AD group there is no reduction in their reaction times on the high conflict resolution trials (incongruent trials that follow incongruent trials) due to their difficulty in making compensatory adjustments to cognitive control that help them to reduce conflict and improve their success rate.

Big Five and psychological and subjective well-being in Colombian older adults.

The goal of the current study was to investigate the relationships between the Five Factor Model of personality and the dimensions of subjective well-being (positive affect, negative affect, and life satisfaction), and psychological well-being (self-acceptance, personal growth, environmental mastery, autonomy, positive relations with others, and purpose in life). Participants included 618 Colombian adults aged 60-92 years. Multiple linear regression analyses were conducted. Regarding the subjective well-being, neuroticism was associated with lower scores on life satisfaction, and positively associated with negative affect, whereas extroversion and conscientiousness were associated with higher scores on life satisfaction and positive affect. For psychological well-being, neuroticism showed a negative and significant association with all of the psychological well-being dimensions, except purpose in life, whereas extroversion and conscientiousness showed a significant and positive relationship with the six dimensions. Neuroticism, extraversion, and conscientiousness represent personality predispositions for general well-being. Extraversion and conscientiousness are predictors of optimal aging. Neuroticism was the only significant predictor of negative affect.

Executive Functions, Episodic Autobiographical Memory, Problem-Solving Capacity, and Depression Proposal for a Structural Equations Model.

The executive functions play an important role in storing and recovering autobiographical memories, especially episodic memories. These types of memories provide information about solutions and experiences from the past that can be utilized as examples in the present when seeking solutions to any problem. In addition, a close relationship between depression and the executive functions has been widely recognized. This study aims to elaborate a structural equations model that empirically supports the relationships among the executive functions, episodic autobiographical memory, and the adaptive capacity to solve problems, taking into account the depressed mood state. In all, 32 healthy elderly people, 32 patients with Parkinson disease, 32 with amnestic mild cognitive impairment, and 32 with Alzheimer disease were evaluated. Structural equation models were estimated to test the effects among the constructs. The final model shows adequate fit indexes, thus revealing that an individual's problem-solving capacity will depend on the capacity to access the episodic autobiographical memory, which in turn will depend on the maintenance of executive functioning. In a parallel way, the mood state, and specifically depression, will play a modulator role because when there is depressive symptomatology, some capacities that depend on executive control can be diminished.

Personality and Emotional Intelligence in Older Adults: A Predictive Model Based on Structural Equations Modeling.

Recent research on emotions in aging points to emotional intelligence (EI) as a factor that plays an important role in this process, and different conceptualizations of EI show that this construct is closely linked to personality in the general population. The main purpose of this study was to find out whether findings obtained in the general population indicating a predictive relationship between personality and EI are also confirmed during the aging process. A sample of 233 healthy older subjects between 60 and 90 years old was used. Participants answered two self-report scales on EI and personality, respectively. Structural equation modeling was used to test the predictive role of personality in EI. Personality was found to be a predictor of EI in older people, and the weight of the prediction was significant in all the dimensions of the big five personality factors, except the dimension of neuroticism, which is known to vary greatly during the aging process. These results indicate that personality influences EI differently in the older adult population, compared to the general population. This is a relevant finding that should be examined further in order to better understand the influence of personality on positive emotional development in this population.

Wellbeing, resilience, and coping: Are there differences between healthy older adults, adults with mild cognitive impairment, and adults with Alzheimer-type dementia?

The changes that occur with cognitive impairment and Alzheimer's disease could affect psychological aspects unrelated to memory. The purpose of this study is to compare 32 healthy older adults, 31 amnestic mild cognitively impaired (aMCI) adults, and 32 patients diagnosed with Alzheimer's disease (AD), in order to determine whether there are differences in their psychological wellbeing, resilience, and coping strategies. Unifactorial MANOVAS and ANOVAS were performed to analyze the between-group differences. The results reveal that the AD group showed lower levels of resilience and orientation toward problem-solving and greater use of religious strategies. In addition, they had significantly lower wellbeing scores than the other groups. The worsening of the pathology impedes the capacity for adaptation and resilience and the application of strategies oriented toward the problem, and it increases the application of strategies based on magical thinking. Moreover, it also produces a reduction in wellbeing.

A Follow-Up Study of a Reminiscence Intervention and Its Effects on Depressed Mood, Life Satisfaction, and Well-Being in the Elderly.

The purpose of this study was to investigate the extent to which a reminiscence intervention reduces depressed mood and improves life satisfaction and psychological well-being. 160 healthy elderly people participated in a 10-session intervention. An experimental design with pretest and posttest evaluations was applied, comparing a control group to an intervention group to evaluate the effects of the program. Follow-up measures were also taken to find out whether the intervention's positive effects lasted over time. Mixed Model ANOVAs showed significant increases in the time-group interaction, life satisfaction, and psychological well-being measures, and decreases in depressed mood, after treatment. The effects remained after three months in the case of life satisfaction and some dimensions of psychological well-being, but they were lower on depressed mood. This study provides additional support for the effectiveness of a reminiscence program as a useful intervention to improve the quality of life of older adults.
