Prenatal maternal anxiety and early childhood temperament

The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.     

Visuospatial skills and their association with math performance in girls with fragile X or Turner syndrome.

The present study was designed to assess object identification ("what") and location ("where") skills among girls with fragile X or Turner syndrome and girls with neither disorder. Participants completed standardized subtests of visual perception and tasks of visuospatial "what" and "where" memory. Girls with fragile X had average performance on most object identification tasks, yet 53% failed to accurately recreate the gestalt of a design during the "where" memory task. Fewer than 7% of girls in the Turner or comparison group made this error. Girls with Turner syndrome had lower scores and longer response times on object perception tasks and had poorer recall of location for internal features of the design on the "where" memory task, relative to girls in the comparison or fragile X group. When limiting analyses to IQ-matched samples, correlations between math and visual perception tasks emerged, but only for girls with fragile X. These results reflect important differences between two cognitive phenotypes and have implications for the role of visuospatial processing in early math performance.     

Maternal perception of infant intentionality at 4 and 8 months

This study examines the degree to which mothers perceive infants as intentional and the relations among perception of intentionality, background variables, maternal emotional adjustment, and maternal interactive style. Forty mother-infant dyads were assessed when the infants were 4 months old, and 34 were retested at 8 months. Parent perception of infant intentionality (PPII) was measured via a rating of videotaped segments of infant behavior and an interview. Intentionality scores showed acceptable internal consistency and were positively intercorrelated at each age and across age. The two measures were aggregated to form an index of PPII at each age. Higher educational attainment was associated with lower PPII scores, experience with infants was associated with higher PPII scores, and academic knowledge about child development was not related to PPII. Mothers with more symptoms of anxiety had lower PPII scores, but high maternal separation anxiety was associated with higher PPII scores. Maternal symptoms of depression had a complex relation to PPII scores. Mothers rated as sensitive in mother-infant interactions had higher PPII scores. These variables accounted for 34% of the variance in PPII at 4 months and 49% at 8 months. There were also group differences: Mothers of 8-month-olds had higher PPII scores than mothers of 4-month-olds, mothers of girls had higher PPII scores than mothers of boys, and mothers attributed more intentionality in episodes with girls than in episodes with boys. The results are discussed in relation to mechanisms whereby PPII interacts with aspects of the parent and infant.     

Visuospatial and mathematical dysfunction in major depressive disorder and/or panic disorder: A study of parietal functioning

The parietal cortex is critical for several different cognitive functions, including visuospatial processing and mathematical abilities. There is strong evidence indicating parietal dysfunction in depression. However, it is less clear whether anxiety is associated with parietal dysfunction and whether comorbid depression and anxiety are associated with greater impairment. The present study compared participants with major depression (MDD), panic disorder (PD), comorbid MDD/PD and controls on neuropsychological measures of visuospatial processing, Judgement of Line Orientation (JLO), and mathematical abilities, Wide Range Achievement Test (WRAT) Arithmetic. Only comorbid MDD/PD was associated with decreased performance on JLO, whereas all psychopathological groups exhibited comparably decreased performance on WRAT Arithmetic. Furthermore, the results were not accounted for by other comorbid disorders, medication use or psychopathology severity. The present study suggests comorbid depression and anxious arousal are associated with impairment in visuospatial processing and provides novel evidence indicating mathematical deficits across depression and/or anxiety. Implications for understanding parietal dysfunction in internalising psychopathology are discussed.     

Trait anxiety,visuospatial processing,and working memory

This experiment assessed the components of Baddeley's working memory system impaired by anxiety during performance of the Corsi Blocks Test. The Corsi task was performed concurrently with different secondary tasks (i.e., articulatory suppression; counting backwards; spatial tapping; simple tapping). Results showed Corsi performance depended mainly on the central executive and visuospatial sketchpad components of working memory. Adverse effects of trait anxiety on the Corsi task were observed on the central executive but not on the phonological loop or the visuospatial sketchpad. These effects were not mediated by state anxiety. The findings indicate for the first time that trait anxiety impairs central executive functioning on a nonverbal task, and that anxiety does not impair functioning of the “slave” systems (i.e., phonological loop; visuospatial sketchpad). Theoretical implications of these findings are discussed.     

Pregnancy-specific stress, prenatal health behaviors, and birth outcomes

OBJECTIVE: Stress in pregnancy predicts earlier birth and lower birth weight. The authors investigated whether pregnancy-specific stress contributes uniquely to birth outcomes compared with general stress, and whether prenatal health behaviors explain this association. DESIGN: Three structured prenatal interviews (N = 279) assessing state anxiety, perceived stress, life events, pregnancy-specific stress, and health behaviors. MAIN OUTCOME MEASURES: Gestational age at delivery, birth weight, preterm delivery (<37 weeks), and low birth weight (<2,500 g). RESULTS: A latent pregnancy-specific stress factor predicted birth outcomes better than latent factors representing state anxiety, perceived stress, or life event stress, and than a latent factor constructed from all stress measures. Controlling for obstetric risk, pregnancy-specific stress was associated with smoking, caffeine consumption, and unhealthy eating, and inversely associated with healthy eating, vitamin use, exercise, and gestational age at delivery. Cigarette smoking predicted lower birth weight. Clinically-defined birth outcomes were predicted by cigarette smoking and pregnancy-specific stress. CONCLUSION: Pregnancy-specific stress contributed directly to preterm delivery and indirectly to low birth weight through its association with smoking. Pregnancy-specific stress may be a more powerful contributor to birth outcomes than general stress.     

Parental Attachment and Body Satisfaction in Adolescents

Insecure attachment can contribute to various psychological problems including body dissatisfaction. It is not clarified which attachment quality, anxiety or avoidance predict lower body satisfaction, and the relationship of maternal and paternal patterns has not been distinguished yet. Our aim was to test these aspects in adolescents. Participants of the large cross-sectional survey were Hungarian children and adolescents (N?=?5214, 51.6?% boys, mean age 14.8 years, SD?=?2.6 years). Measures included self-reported body weight and height data, body satisfaction scale, the Experience in Close Relationships Scale—Relationship Structures, and the Child Depression Inventory. Boys had significantly higher body satisfaction, and worse maternal attachment than girls, who showed worse paternal attachment and higher depression. Higher paternal anxiety and avoidance, and maternal avoidance predicted lower body satisfaction in both genders adjusted for age and BMI (R ²?=?6.1–12.5?%). Depression fully mediated the relationship between dysfunctional maternal attachment and lower body satisfaction in both genders, between dysfunctional paternal attachment and lower body satisfaction in girls, while only partially mediated between dysfunctional paternal attachment and lower body satisfaction in boys. Dysfunctional parental attachment was associated with adolescents’ lower body dissatisfaction, mediated by the level of depression. The importance of paternal attachment was highlighted in boys’ body concerns. Results suggest that handling negative moods, parental anxiety and avoidance may be useful in the case conceptualizations and treatments related to adolescents’ body dissatisfaction that requires further assessment.     

Maternal perinatal mental health: Associations with bonding,mindfulness, and self-criticism at 18 months’ postpartum

The perinatal period is a time of significant transition for women, with changes in maternal mental health from pregnancy to 18 months’ postpartum. This study specifically analyzes maternal self-criticism and mindfulness during pregnancy and at 18 months’ postpartum, and their associations with bonding. A longitudinal study (30 weeks’ gestation–18 months’ postpartum) assessed 32 mother–infant dyads, examining changes in maternal depression, anxiety, self-criticism, and mindfulness. In addition, associations between maternal variables during pregnancy and bonding were investigated. Maternal depression and self-criticism significantly increased from pregnancy to postpartum. Maternal anxiety, self-criticism, and facets of mindfulness during pregnancy were also associated with mother–infant bonding at 18 months. Maternal mental health during pregnancy is subject to change postchildbirth. The lack of control and autonomy accompanying motherhood may result in an increase in self-criticism during this period. Such feelings may elevate a woman's vulnerability to postpartum depression and have consequences for later maternal bonding. Early identification of at-risk mothers is important to increase likelihood of positive outcomes.     

Postnatal depression and infant cognitive and motor development in the second postnatal year: The impact of depression chronicity and infant gender

A large body of literature has investigated the effects of postnatal depression on infant development. However, the particular circumstances in which depression is associated with adverse effects remain unresolved. Factors, such as the nature of depression (e.g., duration and severity) and the context with respect to other risk and protective factors (e.g., socioeconomic status and child gender) have been suggested as moderators of the effects of postnatal depression on infant outcomes. This study examined the impact of brief and chronic depression in a non-poverty sample of 112 mothers and their infants. Infant language development was assessed at 12 months, and at 15 months the Bayley Scales of Infant Development-II were administered. Chronic maternal depression, lasting throughout the first 12 months postpartum and beyond, was associated with lower infant cognitive and psychomotor development, with the effects being similar for boys and girls, while brief depression did not significantly impact the infant performance. Language development and infant behavior during testing were equivalent across the groups. The relatively high rates of motor development delay associated with chronic maternal depression found in this study are discussed along with the methodological issues and models of cumulative risk.     

Attentional networks and visuospatial working memory capacity in social anxiety

Social anxiety is associated with attentional bias and working memory for emotional stimuli; however, the ways in which social anxiety affects cognitive functions involving non-emotional stimuli remains unclear. The present study focused on the role of attentional networks (i.e. alerting, orienting, and executive control networks) and visuospatial working memory capacity (WMC) for non-emotional stimuli in the context of social anxiety. One hundred and seventeen undergraduates completed questionnaires on social anxiety. They then performed an attentional network test and a change detection task to measure visuospatial WMC. Orienting network and visuospatial WMC were positively correlated with social anxiety. A multiple regression analysis showed significant positive associations of alerting, orienting, and visuospatial WMC with social anxiety. Alerting, orienting networks, and high visuospatial WMC for non-emotional stimuli may predict degree of social anxiety.     

Processing efficiency theory in children: working memory as a mediator between trait anxiety and academic performance

Working memory skills are positively associated with academic performance. In contrast, high levels of trait anxiety are linked with educational underachievement. Based on Eysenck and Calvo's (1992) processing efficiency theory (PET), the present study investigated whether associations between anxiety and educational achievement were mediated via poor working memory performance. Fifty children aged 11-12 years completed verbal (backwards digit span; tapping the phonological store/central executive) and spatial (Corsi blocks; tapping the visuospatial sketchpad/central executive) working memory tasks. Trait anxiety was measured using the State-Trait Anxiety Inventory for Children. Academic performance was assessed using school administered tests of reasoning (Cognitive Abilities Test) and attainment (Standard Assessment Tests). The results showed that the association between trait anxiety and academic performance was significantly mediated by verbal working memory for three of the six academic performance measures (math, quantitative and non-verbal reasoning). Spatial working memory did not significantly mediate the relationship between trait anxiety and academic performance. On average verbal working memory accounted for 51% of the association between trait anxiety and academic performance, while spatial working memory only accounted for 9%. The findings indicate that PET is a useful framework to assess the impact of children's anxiety on educational achievement.     

Working memory, psychiatric symptoms, and academic performance at school

Previous studies of the relationship among working memory function, academic performance, and behavior in children have focused mainly on clinical populations. In the present study, the associations of the performance in audio- and visuospatial working memory tasks to teacher reported academic achievement and psychiatric symptoms were evaluated in a sample of fifty-five 6-13-year-old school children. Working memory function was measured by visual and auditory n-back tasks. Information on incorrect responses, reaction times, and multiple and missed responses were collected during the tasks. The children's academic performance and behavioral and emotional status were evaluated by the Teacher Report Form. The results showed that good spatial working memory performance was associated with academic success at school. Children with low working memory performance, especially audiospatial memory, were reported to have more academic and attentional/behavioral difficulties at school than children with good working memory performance. An increased number of multiple and missed responses in the auditory and visual tasks was associated with teacher reported attentional/behavioral problems and in visual tasks with teacher reported anxiety/depressive symptoms. The results suggest that working memory deficits may underlie some learning difficulties and behavioral problems related to impulsivity, difficulties in concentration, and hyperactivity. On the other hand, it is possible that anxiety/depressive symptoms affect working memory function, as well as the ability to concentrate, leading to a lower level of academic performance at school.     

Maternal stress and affect influence fetal neurobehavioral development

The authors investigated the association between maternal psychological and fetal neurobehavioral functioning. Data were provided by 52 maternal-fetal pairs at 24, 30, and 36 weeks gestation. The relations between maternal measures and fetal heart rate, variability, and motor activity were statistically modeled. Fetuses of women who were more affectively intense, appraised their lives as more stressful, and reported more frequent pregnancy-specific hassles were more active across gestation. Fetuses of women who perceived their pregnancy to be more intensely and frequently uplifting and had positive emotional valence toward pregnancy were less active. Associations with fetal heart-rate measures were detected at 36 weeks gestation. These data provide evidence for proximal effects of maternal psychological functioning on fetal neurobehavior.     

IMPACT OF MATERNAL DEPRESSION ON PREGNANCIES AND ON EARLY ATTACHMENT

The relatively high prevalence and duration of depression in the prenatal and postpartum periods reinforce the need for better understanding of maternal depression. The purpose of this article is to explore the main effects of depression to pregnancies’ outcome and to early attachment reviewing research from the last decade and to find the best way to prevent the negative effects of maternal depression to infants. Recent studies have reported significant associations between maternal depression and several adverse obstetric, fetal, and neonatal outcomes. Antenatal depression has been associated with shorter gestation and lower birth weight, with consequences for infant development. A number of studies have demonstrated an association between prenatal depression and attachment difficulties, which seems to play an important mediating role in the development of further adverse outcomes for children. This review reveals some potential risks of untreated depression during the antenatal and postnatal periods, with possibly significant implications for practice and further research. Considering the high prevalence of depression, antenatal detection of depressive symptoms and intervention before childbirth has huge importance in prevention. Early interventions also may need to focus on mother–infant interactions as a key factor of later child development.

Mood and prospective memory

This study considered the relationship between mood states, prospective memory, and retrospective memory among a non-clinical sample of undergraduate students. Multiple regression analyses with simultaneous entry of variables were undertaken to examine the unique contributions of the alternate memory test and the emotional states to memory test performance. As expected, retrospective free recall performance and anxiety made unique and significant contributions to performance on the prospective memory task. However, only prospective memory performance emerged as a significant predictor of retrospective free recall. It is suggested that none of the mood measures emerged as a significant predictor of retrospective memory performance because they do not account for unique variance. In contrast, the relationship between anxiety and prospective memory appears to be due to factors uniquely associated with anxiety, and unrelated to depression.

Stress,sense of coherence and emotional symptoms in adolescents

This paper aims to investigate the association between the domains of stress, sense of coherence (SOC) and emotional symptoms (depression and anxiety) in adolescents, as well as the potential moderating role of SOC on the relationship between stress and emotional symptoms. The study is based on a cross-sectional sample of 1183 adolescents aged 13–18 who attend public elementary and secondary schools in Mid-Norway. The results showed that girls scored higher than boys on stress related to peer pressure, home life, school performance, school/leisure conflict and emotional symptoms. Conversely, boys reported higher SOC than girls. Results from multiple hierarchical regression analyses showed that for boys, stress related to school performance was positively associated with symptoms of both depression and anxiety, whereas stress from peer pressure was associated with depressive symptoms. For girls, stress from peer pressure, romantic relationships and school was associated with more depressive symptoms. SOC was strongly and inversely associated with emotional symptoms, especially anxiety in girls. SOC also moderated the association between stress related to peer pressure and depressive symptoms in both genders. The study provides evidence of the association of SOC with stress and emotional symptoms during adolescence.     

Maternal anxiety and toddler depressive/anxiety behaviors: The direct and moderating role of children's focused attention

Attention mechanisms have a pertinent role in shaping developmental pathways to anxiety and depressive disorders. The current study examined the direct and interactive associations between maternal anxiety symptoms, children's focused attention, and children’s anxiety and depression behaviors in early toddlerhood. Participants were 150 mother-child dyads (50 % female) that were assessed at two time points. At 12 months of child age, mothers reported about their anxiety symptoms and children's focused attention. Children's focused attention was also observed and rated from an individual play task. At 18 months of age, mothers reported about children's anxiety and depression behaviors. Focused attention predicted child anxiety and depressive behaviors, with different patterns of associations between observed and reported measures of attention. There was also a significant interaction between maternal anxiety symptoms and observed children's focused attention. A positive association between maternal anxiety symptoms and child anxiety and depression symptoms was evident only for children with above-average levels of observed focused attention during play. Results suggest that different aspects of focused attention play a role in maternal reported anxiety and depression behaviors in early development and may modulate the intergenerational transmission of anxiety.     

Multi-day Adaptation and Savings in Manual and Locomotor Tasks

Using an individual differences approach, we evaluated whether manual and locomotor adaptation are associated in terms of adaptation and savings across days, and whether they rely on shared underlying mechanisms involving visuospatial working memory or visual field dependence. Participants performed a manual and a locomotor adaptation task during 4 separate test sessions over a 3-month period. Reliable adaptation and savings were observed for both tasks. It was further found that higher visuospatial working memory performance and lower visual field dependence scores were associated with faster learning in the manual and locomotor tasks, respectively. Moreover, adaptation rates were correlated between the 2 tasks in the final test session, suggesting that people may gradually be learning something generalizable about the adaptation process.
