Language and autobiographical memory development from 5 to 12 years: A longitudinal perspective.

The main aim of this study, with two repeated measurements, was to analyze the development of autobiographical memory in a sample of 78 Spanish participants at ages 5 (Time 1; M = 62.43 months, range: 50-74 months) and 12 (Time 2; M = 142.71 months, range: 132-155 months). Data were collected on autobiographical memory and verbal functions. We analyzed the relation between language and autobiographical memory specificity from a longitudinal perspective and assessed the indirect effect of vocabulary in the relationship between age and specific memory at both temporal moments. The results showed that language skills were positively related with autobiographical memory specificity at preschool age, but not at the second measurement. Furthermore, vocabulary scores appear to mediate the relationship between age and autobiographical specificity when children are in the preschool years, but not later. These findings agree with previous research that consider preschool age to be a crucial period for the development of autobiographical memory and its relations with language, but once basic command of language is acquired, linguistic differences impact much less on individual differences in autobiographical specificity.

Effect of the emotional valence of autobiographical memory and parental bonding on depressive symptoms in a community sample.

Retrospective perceptions of parental bonding may be a protective factor for emotional health. These perceptions are grounded in autobiographical memory, which plays a key role in the onset and maintenance of depressive symptomatology. The aim of the present study was to explore whether the emotional valence of autobiographical memories (positive and negative) and the dimensions of parental bonding (care and protection) have an impact on depressive symptomatology, examining the role of depressive rumination and possible age-related differences. A total of 139 young adults (18-28 years) and 124 older adults (65-88 years) completed the Parental Bonding Instrument, the Beck Depression Inventory (BDI-II), the Autobiographical Memory Test and the Short Depressive Rumination Scale. Our results show that positive autobiographical memories serve as a protective factor for depressive symptoms in both young and older adults. Additionally, in young adults, high paternal care and protection scores are associated with increased negative autobiographical memories, although this association has no effect on depressive symptomatology. In older adults, high maternal protection scores are directly related to greater depressive symptomatology. Depressive rumination significantly increases depressive symptoms in both young and older adults, with an increase in negative autobiographical memories in young adults, and a decrease in such memories in older adults. Our findings progress the understanding of the relationships between parental bonding and autobiographical memory with respect to emotional disorders, which, in turn, will help in the design of effective prevention measures.

The role of intolerance of uncertainty and anxiety on compulsive exercise in adolescents.

BACKGROUND AND OBJECTIVES: The role of anxiety as a risk factor for compulsive exercise elements among adolescents is unclear. Intolerance of uncertainty (IU), which is a risk feature for anxiety and eating disorders, may be an important, unexplored risk factor for compulsive exercise dimensions. This study aimed to examine the role of IU dimensions and anxiety on compulsive exercise elements. Given previous evidence indicating gender differences in compulsive exercise and IU levels, gender was included as a moderator. DESIGN/METHODS: A total of 201 adolescent girls and 207 adolescent boys completed the following questionnaires: Eating Disorder Inventory-3, Intolerance of Uncertainty Scale-12 (IUS-12), a brief version of the State-Trait Anxiety Inventory and the Compulsive Exercise Test (CET). RESULTS: The hierarchical regression analyses showed that the interaction between IUS-Prospective and gender emerged as a significant predictor of CET-Avoidance and CET-Weight control exercise beyond symptoms of eating disorders and anxiety. Post hoc analysis revealed that the IUS-Prospective was a significant predictor of CET-Avoidance and CET-Weight Control among boys, but not among girls. CONCLUSIONS: These findings suggest that prospective IU may contribute towards obsessive-compulsive attitudes towards exercise among adolescent population, specifically among boys.

Effects of the use of autobiographical photographs on emotional induction in older adults: a systematic review.

There is evidence to support the positive contribution of autobiographical recall based techniques on individuals' quality of life, mood and cognitive functioning. In this review, we analyzed the effects of the use of personal photographs in interventions based on autobiographical memory in older people with and without cognitive impairment. The PRISMA guidelines for systematic reviews were followed. The search was carried out in the electronic databases Web of Sciences (WOS), Medline (PubMed), SCIELO and PsycInfo (American Psychological Association). The articles based on clinical trials selected were evaluated using the PEDRo scale, which is specific to this type of article. Of the 1098 articles initially found, 6 met the inclusion criteria. The final articles focused their intervention on the use of autobiographical photographs as a means of stimulation. The results show that the use of photographs in different autobiographical recall stimulation techniques is associated with higher scores on well-being and quality of life, as well as with improvements in personal identity and cognitive functioning. This suggests that using personal photographs shows promise in enhancing the effect of these types of interventions in healthy or cognitively impaired older adults.

Effects of affectively-loaded childhood-related photos from the IAPS on the induction of involuntary autobiographical memories in young and older adults.

Objective: Aging produces changes in emotional reactivity and the retrieval of autobiographical memories. The main aim of this study was to assess age-related differences, comparing emotion induction and autobiographical memory recall using photos from the International Affective Picture System (IAPS) that are thematically related to childhood. Method: A cross-sectional observational study was conducted, with the participation of 327 individuals (168 young adults and 159 older adults) with no cognitive impairment and aged between 18 and 88 years. We showed the participants a set of five pictures from the IAPS, the affective content of which was related to childhood. Two of these were considered to be positive images, two negative and one neutral, according to the valence of these pictures in the literature. The main study variables were the reactions associated with emotional valence or pleasure, arousal and dominance, after viewing the photos, and the autobiographical memories retrieved by the participants. Results: The younger adults retrieved a larger number of memories than their older counterparts. As regards the responses to the five affective pictures (IAPS) on valence, arousal and dominance (IAPS), statistically significant differences were only found for pictures 2,345 (BlackEye), with a more positive valence in the group of older adults and higher arousal in the young ones, and 2,312 (Mother), with a more positive valence in the group of older persons. A greater number of memories were retrieved for the photos that generated higher levels of pleasure, greater relaxation and greater emotional control. Conclusion: Of the variables that may be associated with the elicitation of involuntary autobiographical memories, the most significant are age and a positive stimulus.

Effect of popular songs from the reminiscence bump as autobiographical memory cues in aging: a preliminary study using EEG.

Introduction: Music has the capacity to evoke emotions and memories. This capacity is influenced by whether or not the music is from the reminiscence bump (RB) period. However, research on the neural correlates of the processes of evoking autobiographical memories through songs is scant. The aim of this study was to analyze the differences at the level of frequency band activation in two situations: (1) whether or not the song is able to generate a memory; and (2) whether or not the song is from the RB period. Methods: A total of 35 older adults (22 women, age range: 61-73 years) listened to 10 thirty-second musical clips that coincided with the period of their RB and 10 from the immediately subsequent 5 years (non-RB). To record the EEG signal, a brain-computer interface (BCI) with 14 channels was used. The signal was recorded during the 30-seconds of listening to each music clip. Results: The results showed differences in the activation levels of the frequency bands in the frontal and temporal regions. It was also found that the non-retrieval of a memory in response to a song clip showed a greater activation of low frequency waves in the frontal region, compared to the trials that did generate a memory. Discussion: These results suggest the importance of analyzing not only brain activation, but also neuronal functional connectivity at older ages, in order to better understand cognitive and emotional functions in aging.

Emotion Classification from EEG with a Low-Cost BCI Versus a High-End Equipment.

The assessment of physiological signals such as the electroencephalography (EEG) has become a key point in the research area of emotion detection. This study compares the performance of two EEG devices, a low-cost brain-computer interface (BCI) (Emotiv EPOC+) and a high-end EEG (BrainVision), for the detection of four emotional conditions over 20 participants. For that purpose, signals were acquired with both devices under the same experimental procedure, and a comparison was made under three different scenarios, according to the number of channels selected and the sampling frequency of the signals analyzed. A total of 16 statistical, spectral and entropy features were extracted from the EEG recordings. A statistical analysis revealed a major number of statistically significant features for the high-end EEG than the BCI device under the three comparative scenarios. In addition, different machine learning algorithms were used for evaluating the classification performance of the features extracted from high-end EEG and low-cost BCI in each scenario. Artificial neural networks reported the best performance for both devices with an F[Formula: see text]-score of 75.08% for BCI and 98.78% for EEG. Although the professional EEG outcomes were higher than the low-cost BCI ones, both devices demonstrated a notable performance for the classification of the four emotional conditions.

Dimensional and Discrete Emotional Reactivity in Alzheimer's Disease: Film Clips as a Research Tool in Dementia.

BACKGROUND: No studies have been conducted to date on the dimensional and discrete classification of emotions to study the emotional reactivity of older adults with Alzheimer's disease (AD). Additionally, the presentation of film clips with affective content is currently one of the most effective and widely used Mood Induction Procedures (MIPS). However, it has been scarcely used in AD patients. OBJECTIVE: Based on the dimensional and discrete models of emotion, this study examines the emotional reactivity of older adults with AD, using a popular set of film clips to induce emotions. METHODS: We compared the responses of older adults aged over 65-years with mild to moderate AD (n = 15) and a healthy comparison group (n = 17) to six target emotions: disgust, fear, anger, sadness, amusement, and tenderness. RESULTS: The results showed significant differences in the reactivity of fear, anger, and sadness between AD patients and healthy comparison group. However, the responses of the two groups to positive film clips were similar. Only in the amusement clip did the AD participants show a higher intensity response. CONCLUSION: These findings suggest that the characteristic loss of cognitive abilities in AD is related to a reduction in the ability to react to emotional stimuli, especially negative ones. However, these abilities seem to be preserved when it comes to positive emotions. Future research is necessary to investigate whether the positivity effect is present in AD patients.

Determining the ambient influences and configuration of optimised environments for emotional wellbeing of older adults.

It is now widely recognised that aspects such as tiredness or mood state can have an impact on an individual's wellbeing. However, there also exist other less studied factors that might be influential, and whose analysis is important to maximise personal wellbeing. The aim of this study was to determine the influence of a set of 12 selected factors. Using the analysis of a 20-experiment case study by soft computing techniques the intention was to establish the most appropriate configuration for each factor to compose an optimal living environment to foster wellbeing. The analysis revealed that ambient lighting and stress level are the factors that most impact emotional wellbeing. To a lesser extent, being able to take a break, ambient temperature and ambient noise play a relatively determining role. The findings of this work can be used to establish a living environment for older persons that favours their emotional wellbeing. Practitioner summary: This study analyses the level of influence of a set of ambient factors on the emotional wellbeing of older people, conducting, to this end, a series of controlled experiments, and concluding that ambient lighting and stress level are the factors most relevant to promote a better living environment.KEY POINTSOlder adults' emotional interpretation of pictures depends on the environment and ambient factors.Ambient factors, such as lighting and stress, have a significant, positive effect on visual interpretation of stimuli and greater wellbeing.The use of soft computing techniques facilitates the quantification of the influence of factors affecting emotional wellbeing.

Facial Affect Recognition by Patients with Schizophrenia Using Human Avatars.

People with schizophrenia have difficulty recognizing the emotions in the facial expressions of others, which affects their social interaction and functioning in the community. Static stimuli such as photographs have been used traditionally to examine deficiencies in the recognition of emotions in patients with schizophrenia, which has been criticized by some authors for lacking the dynamism that real facial stimuli have. With the aim of overcoming these drawbacks, in recent years, the creation and validation of virtual humans has been developed. This work presents the results of a study that evaluated facial recognition of emotions through a new set of dynamic virtual humans previously designed by the research team, in patients diagnosed of schizophrenia. The study included 56 stable patients, compared with 56 healthy controls. Our results showed that patients with schizophrenia present a deficit in facial affect recognition, compared to healthy controls (average hit rate 71.6% for patients vs 90.0% for controls). Facial expressions with greater dynamism (compared to less dynamic ones), as well as those presented from frontal view (compared to profile view) were better recognized in both groups. Regarding clinical and sociodemographic variables, the number of hospitalizations throughout life did not correlate with recognition rates. There was also no correlation between functioning or quality of life and recognition. A trend showed a reduction in the emotional recognition rate as a result of increases in Positive and Negative Syndrome Scale (PANSS), being statistically significant for negative PANSS. Patients presented a learning effect during the progression of the task, slightly greater in comparison to the control group. This finding is relevant when designing training interventions for people with schizophrenia. Maintaining the attention of patients and getting them to improve in the proposed tasks is a challenge for today's psychiatry.

Autobiographical Memory Impairment in Adolescents in Out-of-Home Care.

Childhood maltreatment is a major risk factor for emotional problems in adolescence and adulthood and has deleterious effects on cognitive functions such as working memory. A key aspect in the study of the cognitive and affective consequences of maltreatment is autobiographical memory, especially regarding the difficulty retrieving specific memories, known as overgeneral memory. In this study, autobiographical memory tests, working memory, and a depressive symptom assessment were administered to 48 adolescents in care with a history of maltreatment (22 abused and 26 neglected) without mental disorder, who had been removed from their family and were living in residential child care, and to 61 adolescents nonmaltreated who had never been placed in care. The results show that adolescents with a history of maltreatment remember fewer specific events (Cohen d = 1.1-1.3) and that both working memory and depressive symptoms are involved in overgeneral memory (R2 = .13-.26). Directions for future research include neuropsychological assessment and implementation of a training program to increase specific memory recall in this population.

Emotional Intelligence and Mental Health in the Family: The Influence of Emotional Intelligence Perceived by Parents and Children.

INTRODUCTION: The relevant scientific literature has confirmed the relationship between emotional intelligence (EI) and mental health. In addition, previous studies have underlined the importance of perceived EI between family members in the construction of one's own EI. Adolescence is considered to be a crucial stage in identity construction and a time when mental health is vulnerable. OBJECTIVES: To analyze the mediating role of self-reported EI on mental health of adolescents and young adults still living in the family home, we considered the relationship between perceived EI in parents and children. METHOD: The sample was comprised of 170 children and their respective fathers and mothers living in the same family home. Self-reported EI was evaluated using the Trait Meta-Mood Scale (TMMS-24), whereas perceived EI was evaluated via the Perceived Emotional Intelligence Scale-24 (PTMM-24) and mental health using the MH-5. RESULTS: Parents' perceived EI of their children also children's perceived EI of their parents has a direct effect on children's mental health and an indirect effect through the EI self-reported by children. We discuss the differences in the role of mothers and fathers in emotional education and its influence on the results. CONCLUSIONS: We highlight the importance of perceived EI among family members, over and above the self-reported EI of each member, for its predictive power on the mental health of children.

Arousal Detection in Elderly People from Electrodermal Activity Using Musical Stimuli.

The detection of emotions is fundamental in many areas related to health and well-being. This paper presents the identification of the level of arousal in older people by monitoring their electrodermal activity (EDA) through a commercial device. The objective was to recognize arousal changes to create future therapies that help them to improve their mood, contributing to reduce possible situations of depression and anxiety. To this end, some elderly people in the region of Murcia were exposed to listening to various musical genres (flamenco, Spanish folklore, Cuban genre and rock/jazz) that they heard in their youth. Using methods based on the process of deconvolution of the EDA signal, two different studies were carried out. The first, of a purely statistical nature, was based on the search for statistically significant differences for a series of temporal, morphological, statistical and frequency features of the processed signals. It was found that Flamenco and Spanish Folklore presented the highest number of statistically significant parameters. In the second study, a wide range of classifiers was used to analyze the possible correlations between the detection of the EDA-based arousal level compared to the participants' responses to the level of arousal subjectively felt. In this case, it was obtained that the best classifiers are support vector machines, with 87% accuracy for flamenco and 83.1% for Spanish Folklore, followed by K-nearest neighbors with 81.4% and 81.5% for Flamenco and Spanish Folklore again. These results reinforce the notion of familiarity with a musical genre on emotional induction.

Effectiveness of the level of personal relevance of visual autobiographical stimuli in the induction of positive emotions in young and older adults: pilot study protocol for a randomized controlled trial.

BACKGROUND: The ability to retrieve specific memories is a cognitive and emotional protective factor. Among the most effective techniques to generate autobiographical memories is the use of audio-visual stimuli, particularly images. Developing and improving techniques that facilitate the generation of such memories could be highly effective in the prevention of depressive symptoms, especially in the elderly population. The aim of the present study is to examine how the level of personal relevance of pictures as autobiographical memory cues to induce positive emotions may affect an individual's emotion regulation. METHODS: The participants, 120 older adults aged 65 and over and 120 young adults aged between 18 and 35, of both sexes and without depressive symptoms, will be induced to a negative mood state by means of viewing a film clip. Following the negative mood induction, the participants will be shown positive images according to experimental group to which they were randomly assigned (high personal relevance: personal autobiographical photographs; medium personal relevance: pictures of favourite locations associated with specific positive autobiographical memories; and low personal relevance: positive images from the International Affective Picture System). We will analyse the differences in subjective (responses to questionnaires) and objectives measures (EEG signal, heart rate variability and electrodermal activity) between the groups before and after the induction of negative affect and following the recall of positive memories. DISCUSSION: The use of images associated with specific positive autobiographical memories may be an effective input for inducing positive mood states, which has potentially important implications for their use as a cognitive behavioural technique to treat emotional disorders, such as depression, which are highly prevalent among older adults.

Functioning of autobiographical memory specificity and self-defining memories in people with cancer diagnosis.

OBJECTIVES: Cognitive and emotional disturbances have been associated with the diagnosis and treatment of cancer. Autobiographical memory is one of the specific cognitive processes affected during this disease. The current study had two main aims: (1) to compare the functioning of autobiographical memory specificity and its related variables (executive functioning, depression and perceived stress) in a group of persons with cancer and a control group; and (2) to analyze whether the experience of cancer evolved into a self-defining memory in the sample of participants diagnosed with this disease. METHOD: The study sample comprised 62 participants, 31 in the group with a cancer diagnosis and 31 in the control group. Autobiographical memory specificity, executive functions, depression, stress and self-defining memory were evaluated in the current study. RESULTS: Depressive symptomatology and reduced executive functioning, but not perceived stress levels, are related and are predictors of autobiographical memory specificity. In addition, the identified characteristics of the self-defining memories were associated with the cancer experience as a threat to physical integrity and an awareness of the meaning of life. CONCLUSION: This emerging research line is especially important in view of its possible impacts on patients' well-being, due to the importance of psychological processes in cancer disease.

How effective are films in inducing positive and negative emotional states? A meta-analysis.

Meta-analyses and reviews on emotion research have shown the use of film clips to be one of the most effective methods of mood induction. Nonetheless, the effectiveness of this method when positive, negative and neutral emotional targets are studied under similar experimental conditions is currently unknown. This comprehensive meta-analysis included only studies that implemented neutral, positive and negative mood inductions to evaluate the effectiveness of the film clip method as a mood induction procedure. In addition, several factors related to the films, sample and experimental procedure used, the number of emotional categories, for example, or the number of film clips watched, were included to study their influence on the effectiveness of this mood induction procedure. Forty-five studies were included with 6675 participants and 12 possible moderator variables according to the sample and the research procedure. Our findings suggest that film clips are especially powerful in inducing negative mood states (Hedges' g for valence = -1.49 and for arousal = -1.77) although they are also effective inducers of positive mood states (Hedges' g for valence of = . -1.22 and for arousal = -1.34). Additionally, this meta-analysis reveals that variables, such as the number of emotional categories or the type of stimulus used to measure the baseline, should be considered.

Testing the properties of the triarchic model of psychopathy in a community sample: Self-reported trait aggression and drug consumption associations.

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive-Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.

Autobiographical memory specificity across life periods in people with schizophrenia.

OBJECTIVE: Because the well-known relationship between autobiographical memory (AM) with social functioning and psychopathology can manifest itself in a different way for memories of different life periods, the current work assesses AM specificity deficits across different life stages in people with schizophrenia. METHOD: This cross-sectional study compares the performance of specific AM in people with a diagnosis of schizophrenia (n = 53, 78% male, 39.03 mean age) and controls ( n = 69, 88% male, 36.65 mean age) for four life periods (childhood, adolescence, early adulthood, and the year preceding the assessment) using the Autobiographical Memory Enquiry. RESULTS: The results revealed worse AM performance in people with schizophrenia, especially for memory of events occurring over the preceding year, and the use of overgeneral memory style for life periods succeeding childhood. CONCLUSION: These results highlight the need for systematic assessment of difficulties in retrieving specific memories across life periods in people with schizophrenia.

Psychometric Properties of the Spanish Short Depressive Rumination Scale in a Nonclinical Sample.

Repetitive negative thinking (RNT) is considered a transdiagnostic variable underlying common symptoms (e.g., depressed mood) across various mood disorders. Depressive rumination is one typical and frequent manifestation of RNT and is a well-known vulnerability factor of depression onset, maintenance and recurrence. Due to the time-related constraints in assessment settings and the association of rumination on sadness with diagnosis of depression, the rapid identification of individuals scoring high on this construct may become a useful screening tool in non-clinical samples. The main aim of the present study was to test the psychometric properties of the Spanish version of the Short Depressive Rumination Scale (SDRS) in a large sample (N = 649). Confirmatory Factor Analysis supported a one-factor model accounting for 75% of variance with an excellent internal consistency (α = .93) in spite of the reduced number of items (4 items). Criterion validity results based on associations with other well-established rumination (sub)scales, age, scores in depression and gender differences, were congruent. The results suggest that the SDRS, the shortest existing scale assessing depressive rumination to our knowledge, can be a useful instrument for a rapid assessment of depressive rumination in community samples.
