Frequency drives lexical access in reading but not in speaking: the frequency-lag hypothesis

To contrast mechanisms of lexical access in production versus comprehension we compared the effects of word frequency (high, low), context (none, low constraint, high constraint), and level of English proficiency (monolingual, Spanish-English bilingual, Dutch-English bilingual) on picture naming, lexical decision, and eye fixation times. Semantic constraint effects were larger in production than in reading. Frequency effects were larger in production than in reading without constraining context but larger in reading than in production with constraining context. Bilingual disadvantages were modulated by frequency in production but not in eye fixation times, were not smaller in low-constraint contexts, and were reduced by high-constraint contexts only in production and only at the lowest level of English proficiency. These results challenge existing accounts of bilingual disadvantages and reveal fundamentally different processes during lexical access across modalities, entailing a primarily semantically driven search in production but a frequency-driven search in comprehension. The apparently more interactive process in production than comprehension could simply reflect a greater number of frequency-sensitive processing stages in production.     

Associations Between Maternal Mental Health and Child Emotional and Behavioral Problems: Does Prenatal Mental Health Matter?

This study examined associations between elevated symptoms of prenatal depression or anxiety and offspring emotional and behavioral problems during mid to late childhood taking into account the impact of later maternal mental health symptoms. The sample consisted of 2,891 women and their children (49 % male) from a prospective, community-based study, the Avon Longitudinal Study of Parents and Children. Women completed measures of depressive (Edinburgh Postnatal Depression Scale) and anxious (Crown Crisp Experiential Index) symptoms at regular intervals beginning in pregnancy. Mothers and teachers assessed offspring emotional and behavioral problems using the Strengths and Difficulties Questionnaire when children were 10–11 years old. Multivariable regression models were fit to address study hypotheses. Exposure to elevated symptoms of maternal depression during pregnancy was associated with increased total offspring emotional and behavioral problems, even after controlling for later maternal mental health problems and a range of sociodemographic and psychosocial characteristics, according to mothers’ but not teachers’ reports. Similarly, children exposed to elevated symptoms of maternal anxiety during pregnancy were reported to have increased total emotional and behavioral problems by mothers but not by teachers. We found support for modest associations between elevated symptoms of maternal depression and anxiety during the prenatal period and certain domains of offspring emotional and behavioral problems in mid to late childhood above and beyond the impact of later maternal mental health problems. These findings highlight the need for additional clinical and research attention to the prenatal period and to both maternal depression and anxiety.     

Cultural Adaptation and Psychometric Validation of the Ages and Stages Questionnaires for use in Georgia

Low- and middle-income countries need simple, technically sound developmental screening tools. The Ages and Stages Questionnaires, 3rd edition (ASQ-3) is widely accepted as a scientifically reliable and valid, user-friendly, and easy-to-learn and administer tool. This study documents the cultural adaptation, validation, and standardization of the Georgian ASQ-3 for children 1–66 months. The parents of 2974 children from one to 66 months completed the Georgian ASQ-3. We compared mean domain scores to the US normative sample, and performed multivariate analyses to detect variables associated with ASQ-3 cutoff scores. Cronbach's alpha values for all age groups varied from 0.643 to 0.824 across areas. We found significant differences in cutoff points between the Georgian ASQ-3 and US reference population in most domains across age groups. Child gender was associated with Communication (B, 0.453; p?=?0.01), Fine Motor (B, 0.457; p?=?0.01) and Personal–Social (B, 0.576; p?=?0.001) with scores for girls more frequently distributed above the cutoff. We found administration of the Georgian ASQ-3 was easy after adaptation. We recommend additional research to investigate sensitivity and specificity and gender differences.     

Linking Family Functioning and Self-Discrepancies among Children with Functional Somatic Symptoms

Functional somatic symptoms (FSS), defined as physical symptoms of unknown pathology, are common among children and adolescents and are often associated with high levels of functional impairment. Self-discrepancy theory (SDT) suggests that discrepancies between one’s ideal, ought, or undesired self-states and one’s actual self-representation may lead to emotional distress. Among families with dysfunctional patterns, such emotional distress may result in FSS. The current study examined the relationship between familial patterns and children’s levels of self-discrepancies, among children with and without FSS. Twenty-three children diagnosed with FSS and 23 children with orthopedic problems (non-FSS) and their mothers participated in the study. Mothers and children completed the Child Somatization Inventory and the Integrated Self-Discrepancies Index. Mothers also completed the general scale of the Family Assessment Device. Higher levels of symptom intensity were found in the FSS group than in the non-FSS group. Dysfunctional familial patterns were significantly higher in the FSS group, and higher levels of discrepancies were reported in the FSS group, compared with the non-FSS group. No significant relationship was found in the FSS group between level of self-state discrepancies and level of family functioning. Higher levels of dysfunctional patterns are observed among families of children with FSS. Furthermore, children with FSS and their mothers hold relatively high levels of self-state discrepancies. However, these elevated discrepancies are not significantly related to familial dysfunctional patterns. Viewing self-state discrepancies together with family maladaptive patterns might help address both inter- and intrapersonal conflicts within the family and reduce children’s symptoms.
