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.     

Support for Leader's Decisions in Conflict and Negotiation: Women Do Not Benefit From Relevant Expertise While Men Do

In the present research, we examined the role of leaders' domain‐specific expertise and gender as affecting individuals' evaluation of proposals related to intergroup conflict. Across three studies, conducted in two different conflict‐related contexts (Israeli‐Palestinian conflict and the refugee crisis in Europe), we showed that men and women do not equally benefit from domain‐specific expertise. Having high (compared to low) domain‐specific expertise positively affected participants' attitudes towards the proposal when its author was a man but not when she was a woman. We further demonstrate that specific characteristics of the proposal (i.e., security relevance) and of the participants (i.e., level of sexism) affect reactions to different negotiation proposals. Our findings suggest that even when women acquire relevant knowledge and experience, they do not benefit from them as much as men. One implication of these findings is that training and enhancing women's expertise may not be enough to eliminate gender bias.     

Standard errors and confidence intervals for correlations corrected for indirect range restriction: A simulation study comparing analytic and bootstrap methods

A frequent topic of psychological research is the estimation of the correlation between two variables from a sample that underwent a selection process based on a third variable. Due to indirect range restriction, the sample correlation is a biased estimator of the population correlation, and a correction formula is used. In the past, bootstrap standard error and confidence intervals for the corrected correlations were examined with normal data. The present study proposes a large-sample estimate (an analytic method) for the standard error, and a corresponding confidence interval for the corrected correlation. Monte Carlo simulation studies involving both normal and non-normal data were conducted to examine the empirical performance of the bootstrap and analytic methods. Results indicated that with both normal and non-normal data, the bootstrap standard error and confidence interval were generally accurate across simulation conditions (restricted sample size, selection ratio, and population correlations) and outperformed estimates of the analytic method. However, with certain combinations of distribution type and model conditions, the analytic method has an advantage, offering reasonable estimates of the standard error and confidence interval without resorting to the bootstrap procedure's computer-intensive approach. We provide SAS code for the simulation studies.     

The curious,context‐dependent case of anger: Explaining voting intentions in three different national elections

Collective action is typically studied in social protest contexts and predicted by different motivations (i.e., ingroup identification and efficacy beliefs, and outgroup‐directed anger). Assuming that voting to some extent reflects a form of collective action, we tested whether these three different motivations predicted voting in Dutch, Israeli, and Italian national election contexts. Based on previous meta‐analyses on voting and collective action, we hypothesized that identification with and efficacy beliefs regarding this party would motivate voting across the different elections (i.e., context‐independent effects). As for anger, we predicted more context‐dependent effects, depending on whether the anger is targeting the previous government or at the political system at large. Results were largely in line with predictions, showing the relatively context‐independent motivational power of party identification and efficacy beliefs, and clearly context‐dependent effects for anger. Specifically, we found little support for a similar motivational power of anger targeting previous government policies, but anger targeting politics in general demotivated Dutch and Israeli participants to vote (interpreted as an expression of political cynicism), while curiously motivating Italian participants to vote (interpreted as a desire for system change from “old” to “new” politics). We discuss these findings in the context of voting in national elections, and recommend further integration of the voting and social protest literatures.     

The importance of decision making in causal learning from interventions

Recent research has focused on how interventions benefit causal learning. This research suggests that the main benefit of interventions is in the temporal and conditional probability information that interventions provide a learner. But when one generates interventions, one must also decide what interventions to generate. In three experiments, we investigated the importance of these decision demands to causal learning. Experiment 1 demonstrated that learners were better at learning causal models when they observed intervention data that they had generated, as opposed to observing data generated by another learner. Experiment 2 demonstrated the same effect between self-generated interventions and interventions learners were forced to make. Experiment 3 demonstrated that when learners observed a sequence of interventions such that the decision-making process that generated those interventions was more readily available, learning was less impaired. These data suggest that decision making may be an important part of causal learning from interventions.     

Extending Free Pregroups with Lower Bounds

In this paper, we propose an extension of free pregroups with lower bounds on sets of pregroup elements. Pregroup grammars based on such pregroups provide a kind of an algebraic counterpart to universal quantification over type-variables. In particular, we show how our pregroup extensions can be used for pregroup grammars expressing natural-language coordination and extraction.     

Psychoneuroimmunology and male infertility: A possible link between stress,coping and male immunological infertility

Abstract

This current study investigated a link between stress and coping with some male infertility problems via psychoneuroimmunological theories. The study was carried out on 77 males who came to a fertility clinic for sperm diagnosis. Appraisal and coping with stress reaction to negative life events and to infertility were related to non-sperm cells within the seminal plasma. Those men who had felt strained from external events and from problems of infertility, and had used emotional escape coping strategies, were more prone to have an immunosuppressed reaction, indicated by bacteria within their plasma. Those using task focused control strategies were more prone to have an immunostimulatory reaction, indicated by white blood cells, including in some cases, sperm destroying phagocytes suggesting a possible auto-immunity reaction. When the analyses were done separately on patients with known male fertility problems in comparison with those with unexplained infertility, the two opposing psychoneuroimmunological processes became more pronounced.
