RESUMO
The present study aims to gain a greater understanding of the manner in which culture may impact parenting and, thus, child development by examining the relationship between cultural values, socialization goals (SGs), and parental ethnotheories (PEs). Specifically, this study examined links between cultural value dimensions (i.e., individualism/collectivism, power distance, masculinity/femininity, uncertainty avoidance, indulgence/restraint, and long-term/short-term orientation; Hofstede et al., 2010) and autonomous as well as relational SGs and PEs. We examined data collected from mothers of toddlers (N = 865) between 17 and 40 months of age (M = 26.88 months, SD = 5.65 months; 52% boys) from 14 nations represented in the Joint Effort Toddler Temperament Consortium. We hypothesized that: (a) Cultural values consistent with independent cultural ideals would be positively associated with SGs and PEs representative of greater autonomy and independence, and (b) Cultural values consistent with interdependent ideals would be positively associated with SGs and PEs representative of greater interrelatedness. Multilevel modeling was used to regress parental psychology on Hofstede's cultural values. Support for these hypotheses was somewhat mixed; higher ratings of culture-level indulgence were associated with higher autonomous PEs, as well as with higher relational and autonomous SGs. Furthermore, higher ratings of culture-level masculinity were associated with lower relational PEs and with lower autonomous SGs. The results suggest differences in the effects for cultural values associated with parenting versus cultural values associated with child outcomes and highlight considerations related to dichotomous cultural frameworks. The findings help explain both individual- and country-level variations in aspects of parental psychology. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
RESUMO
Objectives: The present study examined parental sleep-supporting practices during toddlerhood in relation to temperament across 14 cultures. We hypothesized that passive sleep-supporting techniques (e.g., talking, cuddling), but not active techniques (e.g., walking, doing an activity together), would be associated with less challenging temperament profiles: higher Surgency (SUR) and Effortful Control (EC) and lower Negative Emotionality (NE), with fine-grained dimensions exhibiting relationships consistent with their overarching factors (e.g., parallel passive sleep-supporting approach effects for dimensions of NE). Methods: Caregivers (N = 841) across 14 cultures (M = 61 families per site) reported toddler (between 17 and 40 months of age; 52% male) temperament and sleep-supporting activities. Utilizing linear multilevel regression models and group-mean centering procedures, we assessed the role of between- and within-cultural variance in sleep-supporting practices in relation to temperament. Results: Both within-and between-culture differences in passive sleep-supporting techniques were associated with temperament attributes, (e.g., lower NE at the between-culture level; higher within-culture EC). For active techniques only within-culture effects were significant (e.g., demonstrating a positive association with NE). Adding sleep-supporting behaviors to the regression models accounted for significantly more between-culture temperament variance than child age and gender alone. Conclusion: Hypotheses were largely supported. Findings suggest parental sleep practices could be potential targets for interventions to mitigate risk posed by challenging temperament profiles (e.g., reducing active techniques that are associated with greater distress proneness and NE).
RESUMO
Although, in the last years several studies have moved beyond analyzing the role of mother-child relationship in the association between child temperament and child emotional functioning, our knowledge is still limited about which fine-grained temperamental components of child reactivity and self-regulation are associated with child-teacher relationship quality. Also, fewer studies have looked at the moderating role of child-teacher relationship in the association between child temperament and child internalizing/externalizing problems during early childhood. The present study examined the relation between components of child temperamental Negative Affectivity, Surgency, and Effortful Control and child-teacher relationship quality (i.e., closeness, conflict) in preschool children. In addition, our aim was to test the moderating effect of the child-teacher relationship on the association between temperament and internalizing and externalizing problems. One hundred Romanian preschoolers (55 boys, mean age = 4.04 years) participated in this study. Mothers assessed their child's temperament by completing the Children's Behavior Questionnaire and externalizing and internalizing problems with the Child Behavior Checklist. Child-teacher relationship quality was evaluated by children's teachers using the Student-Teacher Relationship Scale. Our results revealed that teachers rated their relationship as less conflictual with children who were assessed by their mothers as better in shifting and focusing attention, enjoying situations involving low stimulus intensity and displaying higher levels of Shyness, Sadness and Activity Level. Moreover, higher levels of Discomfort were associated with more conflict and less closeness while emotional reactivity such as Sadness, Fearfulness, and Activity Level were positively associated with closeness. Teacher-child closeness was associated with three temperamental self-regulation factors in the expected direction, except inhibitory control. Furthermore, results revealed a statistically significant interaction between child temperamental Shyness and child-teacher closeness in the prediction of child internalizing problems. Thus, when child-teacher closeness was low, there was a significant and positive relationship between child temperamental Shyness and child internalizing problems. Results highlight the importance of child-teacher relationship quality in relation to child temperament and social-emotional development during preschool period.
RESUMO
Recent empirical evidence shows heterogeneity in the expression of shyness in children. Some children tend to express their shyness displaying positive affect along with gaze aversions (positive shyness), whereas others display more negative emotional reactions accompanied by gaze aversions (negative shyness). Temperamental differences in approach-avoidance tendencies are likely to explain these differences in shyness expression in children and influence their visual attention to social stimuli, yet little empirical attention has been devoted to these associations. Our study examined the temperamental profile (approach, fear, and inhibitory control) associated with positive and negative shyness and the relation between expression of shyness and attention to social stimuli in 47 children aged 3-6 years. Children's positive and negative expressions of shyness were assessed using a performance task. Visual attention to facial emotional expressions was measured with the dot - probe task, and temperament was measured with maternal reports. Positive shyness was found to be positively associated with temperamental dimensions of approach, inhibitory control, and fear. Positive shyness was significantly associated with attentional orientation to positive facial expressions and with less attentional avoidance of threatening facial expressions. Negative shyness was positively associated only with temperamental fear, and no associations were found with attention to social stimuli. Our study provides empirical support for the association between temperament and the multidimensional character of the expression of positive shyness and adds relevant evidence regarding the connection between the expression of shyness and attention to social stimuli.

Television exposure in early childhood has increased, with concerns raised regarding adverse effects on social-emotional development, and emerging self-regulation in particular. The present study addressed television exposure (i.e., amount of time watching TV) and its associations with toddler behavioral/emotional dysregulation, examining potential differences across 14 cultures. The sample consisted of an average of 60 toddlers from each of the 14 countries from the Joint Effort Toddler Temperament Consortium (JETTC; Gartstein & Putnam, 2018). Analyses were conducted relying on the multi-level modeling framework (MLM), accounting for between- and within-culture variability, and examining the extent to which TV exposure contributions were universal vs. variable across sites. Effects of time watching TV were evaluated in relation to temperament reactivity and regulation, as well as measures of emotional reactivity, attention difficulties, and aggression. Results indicated that more time spent watching TV was associated with higher ratings on Negative Emotionality, emotional reactivity, aggression, and attention problems, as well as lower levels of soothability. However, links between TV exposure and both attention problems and soothability varied significantly between cultures. Taken together, results demonstrate that increased time spent watching television was generally associated with dysregulation, although effects were not consistently uniform, but rather varied as a function of culturally-dependent contextual factors.

PURPOSE: Rheumatoid arthritis (RA) is a chronic inflammatory systemic disease associated with various degrees of impairment across different cognitive domains. We aimed to provide a detailed computerized investigation of verbal and visuospatial short-term and working memory (dys)functions in RA patients, assessing both accuracy and response speed, while relating them to age, disease-related activity, affective problems, psychomotor speed and other clinical parameters. PATIENTS AND METHODS: The study included 29 RA patients (mean age 50.6 ± 12.3 years, 79% female) and 30 controls (matched according to age, gender and education), assessed with short-term and working memory tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB) and the Automated Working Memory Assessment (AWMA). RESULTS: RA patients were significantly slower on the basic processing speed test (Motor Screening Test, p =0.003). Their short-term information storage (verbal and visuospatial) was comparable to controls, yet this similar accuracy came at the expense of a longer response time to retain information correctly (on spatial span, p = 0.04). On tasks with higher executive demands, both visuospatial and verbal working memory were compromised, as RA patients took longer (p = 0.004) and had a higher number of total errors (p = 0.02) when conducting a strategic memory-guided search (Spatial Working Memory), and had a significantly lower verbal working memory span on the backwards digit recall test (p = 0.02). CONCLUSION: The findings of this study emphasize the usefulness of performing computerized tests to detect subtle signs of cognitive impairment and of intact performance, which can inform memory training protocols for this vulnerable population.
RESUMO
Over the recent years, there is growing recognition of the social and cultural regulatory processes that act upon individual emotions. The adult-to-child social regulation of emotion is even more relevant, given the development of child self-regulatory abilities during early years. Although it is acknowledged that parental regulatory attempts to their children's emotional expressions are influenced by cultural models, relatively little is known about the specific relationship between parental cultural models and socialization practices that foster emotion self-regulation, particularly in the case of toddlers. Therefore, in the present study, our first aim was to examine, in a Romanian sample of mother-toddler dyads, the relationships between maternal cultural model of self and maternal regulatory attempts targeting toddlers' emotions during a delay of gratification task, while controlling for maternal perceptions of child individual characteristics, namely temperament. The second aim was to analyze, within the delay of gratification task, the relations between maternal regulatory attempts, child regulatory strategies and child affect expression, as the outcome of emotion regulation. Results showed that mothers scored higher for Independence as compared to Interdependence dimensions of self-construal. Also, the multidimensional analysis of self-construal revealed that Autonomy/Assertiveness scores were significantly higher than Relational Interdependent scores. Moreover, different dimensions of Independence predicted different maternal regulatory strategies employed during the delay of gratification task. This pattern of results suggests that maternal representations of an independent self, evidenced in our sample, are reflected in regulatory practices, aimed to develop primary control in the toddler. Moreover, our data revealed several significant associations between maternal regulatory strategies and child regulatory strategies expressed during the delay of gratification task. Finally, we demonstrated that child self-regulation mediated the relation between maternal regulatory attempts and child expression of affect during this task.
RESUMO
The present study examined the independent contributions and the interaction effects of oppositional defiant problems (ODD), callous unemotional traits (CU) and anxiety symptoms on attentional orienting to emotional faces, in a community sample of preschoolers. Additionally, based on Rothbart's (2007) model of temperament, we analyzed whether fine-grained dimensions of reactivity (fear, anger, discomfort, sadness, activity level, approach, high intensity pleasure, impulsivity) and self-regulation (attentional shifting, attentional focusing, inhibitory control), as well as the higher order temperamental factors of negative affectivity, surgency and effortful control are associated with CU traits and ODD-related problems. Attentional orienting to emotional faces was assessed with pictorial Dot-probe task, while teachers rated CU traits and ODD-related problems. Also, parents reported on ODD-related problems, anxiety and temperament. Results indicated significant interaction effects between ODD-related problems and CU, as well as between CU and anxiety, in predicting attentional orientation patterns for angry, fearful and happy faces. Moreover, temperamental reactivity was positively associated with CU traits and ODD-related problems, whereas temperamental self-regulation was negatively related to CU traits and ODD-related problems. Results of this study have implications for early intervention and prevention approaches targeting preschool oppositional defiant problems.
RESUMO
The integration of the folk affect concept of "contempt" into the analysis of the complex institution known generally as charivari is mutually beneficial for both ethno-anthropology (which may thus access inner causes for disputed social and collective behaviors) and evolutionary psychology (which may thus study the length of tradition together with the width of the institution spread, serving the same social functions).

This study examined the effects of individual differences in temperamental reactivity (fear) and self-regulation (attentional control) on attentional biases toward threat in a sample of school-aged children (age range was between 9 years 1 month and 13 years 10 months). Attentional biases were assessed with pictorial Dot-probe task, comparing attention allocation toward angry (threat-related) vs. neutral and happy faces. Children also completed self-report temperamental measures of fear and attentional control. We compared attentional bias scores in 4 groups of children: high/low fear and high/low attentional control. Results indicated that, in the case of children with high fear and low attentional control, attention was significantly biased toward angry faces compared with children who had low fear and low attentional control. Findings are discussed in terms of the moderating role of individual differences in attentional control in the context of threat, anxiety-related attentional biases in children.
RESUMO
It has been conjectured that basic individual differences in attentional control influence higher-level executive functioning and subsequent academic performance in children. The current study sets out to complement the limited body of research on early precursors of executive functions (EFs). It provides both a cross-sectional, as well as a longitudinal exploration of the relationship between EF and more basic attentional control mechanisms, assessed via children's performance on memory storage tasks, and influenced by individual differences in anxiety. Multiple measures of verbal and visuospatial short-term memory (STM) were administered to children between 3 and 6 years old, alongside a non-verbal measure of intelligence, and a parental report of anxiety symptoms. After 9 months, children were re-tested on the same STM measures, at which time we also administered multiple measures of executive functioning: verbal and visuospatial working memory (WM), inhibition, and shifting. A cross-sectional view of STM development indicated that between 3 and 6 years the trajectory of visuospatial STM and EF underwent a gradual linear improvement. However, between 5 and 6 years progress in verbal STM performance stagnated. Hierarchical regression models revealed that trait anxiety was negatively associated with WM and shifting, while non-verbal intelligence was positively related to WM span. When age, gender, non-verbal intelligence, and anxiety were controlled for, STM (measured at the first assessment) was a very good predictor of overall executive performance. The models were most successful in predicting WM, followed by shifting, yet poorly predicted inhibition measures. Further longitudinal research is needed to directly address the contribution of attentional control mechanisms to emerging executive functioning and to the development of problematic behavior during early development.
RESUMO
The aim of this article is to describe the roles of water channel proteins (WCPs) in some neurological diseases in which the implications of these proteins became obvious in the decades after the discovery of WCPs of their presence in the CNS. The diseases which were selected for this review include: epilepsies, muscular dystrophies, amyotrophic lateral sclerosis, neuromyelitis optica, Parkinson's disease, and spongiform encephalopathies. The priorities of Benga group from Cluj-Napoca, Romania, are mentioned, such as the idea of a generalized membrane defect affecting water permeability in epilepsy and in Duchenne muscular dystrophy. Some of these neurological disorders discussed in this article appeared to be water channelopathies. A typical example is neuromyelitis optica (NMO), in which the identification of the specific marker autoantibody against aquaporin 4 in the sera of patients was a milestone in the diagnosis. This has aided understanding of the pathogenesis of NMO and led to better control of its treatment. However, further studies are needed to characterize the function and regulation of WCPs in other neurological diseases, in particular to determine if modulation of WCP function may provide a novel approach to therapy in such diseases.

The present study examined the associations between attentional biases to threat, attentional control and anxiety in a sample of children aged 9 to 14. It was hypothesised that the association between attentional biases toward threat and anxiety might be stronger when the ability to control attention is reduced. The study employed pictures of neutral, happy and angry facial expressions as they have greater ecological value compared to words. Children completed a dot-probe task measuring attentional biases toward such stimuli. They also completed the Spence child anxiety scale for anxiety symptoms and, for attentional control, the child version of the attention control scale measuring the ability to focus and shift attention. Results of a hierarchical regression analysis showed that attentional control significantly explained anxiety. Furthermore, the interaction between attentional control and attentional biases significantly explained anxiety level. These results indicate that attentional control moderates the relation between attentional biases toward threatening facial expressions and anxiety in children. Additionally, a discussion about a possible protective role of attentional control is provided.

Newborns cry in response to another newborn cry and researchers agree that these are the very early signs of empathy development. Yet, little is known about the development of these affect sharing reactions in infancy, beyond the very first few days after birth. The aim of this study is to investigate the presence of contagious cry phenomenon in infancy. Infants aged 1-, 3-, 6-, and 9-month-old were presented with the sound of another infant cry vocalizations. Their emotional reactions were recorded in terms of vocal (presence of vocal distress, latency, and intensity) and facial (anger and sadness) expressions of emotions. Results show that during the presentation of a pain cry sound, 1, 3, 6, and 9 months old infants manifest increased vocal and facial expressions of distress. These affect sharing reactions do not decrease with age. Both boys and girls manifest similar levels of contagious crying reactions. The results are discussed in terms of early empathy development.

In self-paced auditory memory span tasks, the microanalysis of response timing measures represents a developmentally sensitive measure, providing insights into the development of distinct processing rates during recall performance. The current study first examined the effects of age and trait anxiety on span accuracy (effectiveness) and response timing (efficiency) measures from word and digit span performance in a preschool sample (N=76, mean age=57 months, SD=11). Children were reassessed 8 months later using the same two tasks plus a test of nonword memory span and a measure of articulation rate. The results at the second time point (T2) confirmed the effects of age on both processing effectiveness and efficiency. Trait anxiety was an additional negative predictor of span effectiveness (especially for digit span) and efficiency (in the case of word and nonword span). The findings are discussed in the context of factors contributing to early short-term memory development and attentional control theory.

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant.

Despite the circumstantial and sometimes equivocal support, the hypothetic involvement of aluminum (Al) in the etiology and pathogenesis of Alzheimer's disease (AD) has subsisted in neuroscience. There are very few other examples of scientific hypotheses on the pathogenesis of a disease that have been revisited so many times, once a new method that would allow a test of Al's accumulations in the brain of AD patients or a comparison between Al-induced and AD neuropathological signs has become available. Although objects of methodological controversies for scientists and oversimplification for lay spectators, several lines of evidence have strongly supported the involvement of Al as a secondary aggravating factor or risk factor in the pathogenesis of AD. We review evidence on the similarities and dissimilarities between Al-induced neurofibrillary degeneration and paired helical filaments from AD, the accumulation of Al in neurofibrillary tangles and senile plaques from AD, the neuropathological dissociation between AD and dialysis associated encephalopathy, and the epidemiological relations between Al in drinking water and the prevalence of AD. We also critically analyze the prospects of Al-amyloid cascade studies and other evolving lines of evidence that might shed insights into the link between Al and AD. The message between the lines of the following article is that the involvement of Al in the pathogenesis of AD should not be discarded, especially in these times when the amyloid dogma of AD etiology shows its myopia.

BACKGROUND: To determine whether early imitative responses fade out following the maturation of attentional mechanisms, the relationship between primitive imitation behaviors and the development of attention was examined in 4-month-old infants. They were divided into high and low imitators, based on an index of imitation. The status of attention was assessed by studying inhibition of return (IOR). Nine-month-old infants were also tested to confirm the hypothesis. RESULTS: The IOR latency data replicate previous results that infants get faster to produce a covert shift of attention with increasing age. However, those 4-month-olds who showed less imitation had more rapid saccades to the cue before target presentation. CONCLUSION: The cortical control of saccade planning appears to be related to an apparent drop in early imitation. We interpret the results as suggesting a relationship between the status of imitation and the neural development of attention-related eye movement.
