EFFECTS OF MATERNAL DEPRESSION AND PANIC DISORDER ON MOTHER-INFANT INTERACTIVE BEHAVIOR IN THE FACE-TO-FACE STILL-FACE PARADIGM

The present study evaluated the interactive behavior of three groups of mothers and their 3-month-old infants in the Face-to-Face Still-Face paradigm. The mothers had either a clinical diagnosis of major depressive disorder (MDD, n = 33) with no comorbidity, a clinical diagnosis of panic disorder (PD, n = 13) with no comorbidity, or no clinical diagnosis (n = 48). The sample was selected to be at otherwise low social and medical risk, and all mothers with PD or MDD were in treatment. The findings indicated that (a) infants of mothers with PD or MDD displayed the traditional still-face and reunion effects described in previous research with nonclinical samples; (b) the 3-month-old infants in this study showed similar, but not identical, gender effects to those described for older infants; and (c) there were no patterns of maternal or infant interactive behavior that were unique to the PD, MDD, or control groups. These results are discussed in light of mothers' risk status, receipt of treatment, severity of illness, and comorbidity of PD and MDD.     

The Philosophy of Osman bin Bakar

This article examines the philosophy that Osman bin Bakar has published in English. Beginning with his biography and theoretical groundings, and especially the influences that Greek, Chinese, Indian, and Islamic philosophers have had on his thought, the article then turns to Bakar's philosophy of science, ‘ilm al‐tawhīd, how knowledge about the world should be classified, and especially evolutionary theory within Islamic philosophy. These developments in philosophical grounding provide Bakar with a platform to suggest how science can be used as a vehicle for inter‐civilizational dialogue.     

Modeling the Information Preferences of Parents of Children with Mental Health Problems: A Discrete Choice Conjoint Experiment

Although materials informing parents about children’s mental health (CMH) problems can improve outcomes, we know relatively little about the design factors that might influence their utilization of available resources. We used a discrete choice conjoint experiment to model the information preferences of parents seeking mental health services for 6 to 18 year olds. Parents completed 30 choice tasks presenting experimentally varied combinations of 20 four-level CMH information content, transfer process, and outcome attributes. Latent class analysis revealed three segments with different preferences. Parents in the Action segment (43%) chose materials providing step-by-step solutions to behavioral or emotional problems. They preferred weekly meetings with other parents and coaching calls from a therapist. The Information segment (41%) chose materials helping them understand rather than solve their child’s problems. These parents were more sensitive to logistical factors such as receiving information in groups, the location where information was available, the modality in which the information was presented, and the time required to obtain and use the information. The Overwhelmed segment (16%) reported more oppositional and conduct problems, felt their children’s difficulties exerted a greater adverse impact on family functioning, and reported higher personal depression scores than those in the Action or Information segments. Nonetheless, they did not choose information about, or solutions to, the problems their children presented. Simulations predicted that maximizing utilization and realizing the potential benefits of CMH information would require knowledge transfer strategies consistent with each segment’s preferences.

Types of Aggression,Responsiveness to Provocation,and Callous-unemotional Traits in Detained Adolescents

The present study investigated differences in the behavioral and psychophysiological responses to provocation and in the level of callous-unemotional traits in boys exhibiting different patterns of aggression. Eighty-five boys (ages 13-18) in a juvenile detention center played a competitive computer task against a hypothetical peer who provided low and high levels of provocation. Youth high on both self-reported reactive and proactive aggression showed different behavioral responses to provocation than youth high on only reactive aggression. Specifically, the combined group showed high levels of aggressive responses without any provocation, whereas the group high on reactive aggression showed an increase in aggressive responding to low provocation. Further, results revealed a trend for the combined group to show lower levels of skin conductance reactivity to low provocation if they were also high on callous-unemotional traits.     

Why did I right that? Factors that influence the production of homophone substitution errors

Despite considerable research on language production errors involving speech, little research exists in the complementary domain of writing. Two experiments investigated the production of homophone substitution errors, which occur when a contextually appropriate word (e.g., beech) is replaced with its homophone (e.g., beach tree). Participants wrote down auditorily presented sentences containing dominant or subordinate homophones. Homophones were preceded by a lexical prime that overlapped in phonology and orthography (e.g., teacher) or only orthography (e.g., headmaster) with the target homophone. Results showed more substitution errors when the context elicited a subordinate homophone than when it elicited a dominant homophone. Furthermore, both types of primes equivalently increased production of homophone errors relative to control words (e.g., lawyer), suggesting that only orthographic overlap between the prime and target was necessary to influence errors. These results are explained within dual-route models of spelling, which postulate an interaction between lexical and sublexical routes when spelling.     

Implicit depression and hopelessness in remitted depressed individuals

Cognitive theories of depression posit that automatically activated cognitive schemas, including negative thoughts about the self and the future, predispose individuals to develop depressive disorders. However, prior research has largely examined these constructs using explicit tests in currently depressed individuals. Using the Implicit Association Test (IAT), the present study examined automatic associations between the self and mood state ("depression IAT") and between the future and mood state ("hopelessness IAT") before and after a negative mood induction in 19 remitted depressed individuals and 23 healthy controls. In the depression IAT, remitted depressed participants exhibited an overall lower tendency to associate themselves with happiness relative to the healthy controls before the mood induction. Control, but not remitted depressed, participants' automatic associations between the self and happiness diminished following the mood induction. Contrary to our hypotheses, no significant findings emerged when considering the hopelessness IAT. Consistent with prior studies, no significant correlations emerged between implicit and explicit biases, suggesting that these measures probe different processes. Results extend prior IAT research by documenting the presence of a reduced tendency to associate the self with happiness in a sample at increased risk for depression.     

Adolescent family experiences and educational attainment during early adulthood

In this study, the authors investigated the degree to which a family investment model would help account for the association between family of origin socioeconomic characteristics and the later educational attainment of 451 young adults (age 26) from 2-parent families. Parents' educational level, occupational prestige, and family income in 1989 each had a statistically significant direct relationship with youths' educational attainment in 2002. Consistent with the theoretical model guiding the study, parents' educational level and family income also demonstrated statistically significant indirect effects on later educational attainment through their associations with growth trajectories for supportive parenting, sibling relations, and adolescent academic engagement. Supportive parenting and sibling relations were linked to later educational attainment through their association with adolescent academic engagement. Academic engagement during adolescence was associated with educational attainment in young adulthood. These basic processes operated similarly regardless of youths' gender, target youths' age relative to a near-age sibling, gender composition of the sibling dyad, or gender of parent.     

What do children learn about biology from factual information? A comparison of interventions to improve understanding of contagious illnesses

Background . Children have been shown to hold misconceptions about illness, and previous work has indicated that their knowledge can be improved through the use of interventions. Aims . This study aims to evaluate interventions based on the provision of factual information for improving understanding of contagious illness. Sample . The participants were 96 children from two age groups: 7 and 11 years. Methods . During the pre‐test, the children were asked about three contagious illnesses and one novel illness. There were three intervention conditions, differing in the level of factual information provided: explanations provided, no explanations provided and scientific factual style. The interventions were focused on contagious illnesses (cold, chickenpox). A post‐test was conducted 6 weeks later. Results . Results from the pre‐test show that the older children have more sophisticated understanding of illness than the younger children. Mean pre‐ to post‐test change was calculated and analyses revealed that there is greater pre‐ to post‐test change in the explanation and scientific fact conditions when compared with that in the no‐explanation condition. The improvements in knowledge generalized to other contagious illnesses, and the older children showed more improvements than the younger children. Conclusions . These findings add to the literature on children's understanding of contagious illnesses and contribute towards discussions on the best approach to health education.     

Number words in young children's conceptual and procedural knowledge of addition, subtraction and inversion

Three studies addressed children's arithmetic. First, 50 3- to 5-year-olds judged physical demonstrations of addition, subtraction and inversion, with and without number words. Second, 20 3- to 4-year-olds made equivalence judgments of additions and subtractions. Third, 60 4- to 6-year-olds solved addition, subtraction and inversion problems that varied according to the inclusion of concrete referents and number words. The results indicate that number words play a different role in conceptual and procedural development. Children have strong addition and subtraction concepts before they can translate the physical effects of these operations into number words. However, using number words does not detract from their calculation procedures. Moreover, consistent with iterative relations between conceptual and procedural development, the results suggest that inversion acquisition depends on children's calculation procedures and that inversion understanding influences these procedures.     

Female sexual orientation and menstrual influences on person perception

Heterosexual women have previously been shown to display enhanced sensitivity to information that is both reproductively- and sexually-relevant (e.g., sexually mature male faces) during phases of high fertility. In the present study, homosexual women who maintained a regular menstrual cycle and did not use hormonal contraceptives completed a sex-categorization task at periods of high and low fertility within their menstrual cycle. For homosexual women there is a separation between reproductively-relevant (i.e., sexually mature males) and sexually-relevant (i.e., sexually mature females) targets. Our participants showed enhanced sensitivity to sexually-relevant information (i.e., female faces) at high fertility but showed no fluctuation in sensitivity to reproductively-relevant information (i.e., male faces) across testing sessions. These findings are considered in terms of adaptive person perception and the impact of sexual desire on mate preferences.
