Effects of contextual diversity on semantic decision and reading aloud: evidence from a word learning study in English as a second language / Efectos de la diversidad contextual en la decisión semántica y la lectura en voz alta: evidencia de un estudio de aprendizaje de palabras en inglés como segundo idioma

This experiment investigated contextual diversity effects on novel word learning in English as a second language (L2). A group of advanced English speakers, whose native language was Spanish, participated in the study. Participants learned the meaning of real but obscure words that were embedded in either two or 12 different sentences and learned over two days (frequency of exposure was kept constant). On day three, participants were tested using reading aloud and semantic decision tasks. The results showed that participants learned the meaning of words in both conditions fairly well as revealed by their accuracy in the semantic decision task. However, words experienced in 12 different contexts generated more accurate and faster reaction times (RTs), suggesting the acquisition of more robust semantic representations. Strikingly, reading latencies were also faster for the 12-sentence condition, which might imply that semantics has an effect on reading newly learned words in English as a second language. These results are discussed and accommodated in view of the DRC and the PDP models of single-word reading.     

Sibling Death and Adult Maladjustment Indices: A Brief Report

While symptoms of grief pose the most immediate psychological concern in the aftermath of sibling death, emerging research suggests that distal correlates may include strained interpersonal relations and externalized forms of psychological distress. College students with a history of Sibling Loss (n = 36), Parental Loss (n = 32), or No Loss (n = 367) were compared on the Minnesota Multiphasic Personality Inventory (MMPI-2). Sibling Loss was associated with higher Psychopathic Deviate (Pd; d = .62) and Hypomania (d = .42) scores. The relative risk (RR = 2.96) of a Pd elevation (T > 65) was higher after sibling death.     

A preliminary study of the comfort of paced respiration

In order to obtain basal information about what type of externally paced respiration is comfortable, 25 male and 25 female undergraduate students were asked to practice self‐paced respiration. After a 1‐min rehearsal following instructions on comfortable self‐paced respiration, subjects carried out 2 min of self‐paced respiration and rated their level of comfort on a scale of 1–5. This was repeated (up to a maximum of seven times) until the subject recorded a high rating. Results indicated that self‐paced respiration was most comfortable, irrespective of sex, when a respiratory pattern was attained of half the respiratory rate and nearly twice the tidal volume of the trainee's resting condition. Although respiratory sinus arrhythmia and heart rate were indicative of a decrease in cardiac vagal activity and end‐tidal PCO₂ was suggestive of a reduction in anxiety, these effects were small. The results have implications for the utilization of externally paced respiration.

An overview of malingering and deception in neuropsychiatric cases

Forensic practitioners must shoulder special responsibilities when evaluating over-stated pathology (e.g., malingering) as well as simulated adjustment. Such determinations may modify or even override other clinical findings. As a result, practitioners must be alert to their own misassumptions that may unintentionally bias their conclusions about response styles. Detection strategies for malingering—based on unlikely or markedly amplified presentations—are highlighted in this article. Given page constraints, assessment methods for feigning are succinctly presented with their applications to administrative, civil, and criminal referrals.     

A Typology of Interactional Patterns Between Youth and Their Stepfathers: Associations with Family Relationship Quality and Youth Well‐Being

Stepfamilies are an increasingly common family form, many of which are headed by a resident mother and stepfather. Stepfather–child relationships exert notable influence on stepfamily stability and individual well‐being. Although various stepfather roles have been observed, more research is warranted by which stepfather–child interactions are explored holistically and across a variety of life domains (e.g., recreational, personal, academic, and disciplinary). Thus, the primary purpose of the current study is to explore varying interactional patterns between youth and their stepfathers. A latent class analysis is conducted using a representative sample of 1,183 youth (53% female; mean age = 15.64 years, SD = 1.70 years; 62% non‐Hispanic White) residing in mother–stepfather families from Wave I of the National Longitudinal Study of Adolescent to Adult Health. Latent‐class enumeration processes support a four‐class solution, with latent classes representing inactive, academically oriented, casually connected, and versatile and involved patterns of youth–stepparent interaction. Notable differences and similarities are evident across patterns with respect to family relationship quality, youth well‐being, and socio‐demographic characteristics. Differences are most stark between the inactive and versatile and involved patterns. Ultimately, the results showcase notable variation in youth–stepparent interactional patterns, and one size does not necessarily fit all stepfamilies. Family practitioners should be mindful of variation in youth–stepparent interactional patterns and assist stepfamilies in seeking out stepparent–child dynamics that are most compatible with the needs and dynamics of the larger family system.     

Marital Processes Linking Gender Role Attitudes and Marital Satisfaction Among Mexican‐Origin Couples: Application of an Actor–Partner Interdependence Mediation Model

Informed by dyadic approaches and culturally informed, ecological perspectives of marriage, we applied an actor–partner interdependence mediation model (APIMeM) in a sample of 120 Mexican‐origin couples to examine (a) the associations linking Mexican immigrant husbands’ and wives’ gender role attitudes to marital satisfaction directly and indirectly through marital processes (i.e., warmth and negativity) and (b) whether the associations between spouses’ gender role attitudes and marital processes were moderated by wives’ employment. Although previous research has identified spouses’ gender role attitudes as potential predictors of spouses’ marital satisfaction, no study has examined these links in a dyadic model that elucidates how gender role attitudes may operate through processes to shape marital satisfaction and conditions under which associations may differ. We found that when spouses reported less sex‐typed attitudes, their partners reported feeling more connected to them and more satisfied with the marriage, regardless of whether wives were employed. Our results suggest that marital satisfaction was highest for those Mexican‐origin couples in which marital partners were less sex‐typed in their attitudes about marital roles to the extent that partners’ attitudinal role flexibility promoted spouses’ feelings of warmth and connection to their partner.     

Mother‐Stepfather Coparenting in Stepfamilies as Predictor of Child Adjustment

Coparenting between biological parents is a strong predictor of child adjustment. To date, however, little is known about the coparenting dynamics between parent and stepparent in stepfamilies. This study aimed at exploring the links between coparenting in the mother–stepfather dyad and child behavior in stepfamilies compared with the links between mother–father coparenting and child behavior in first‐marriage families. Two modes of coparenting were assessed: overt coparenting, that is, coparental behaviors in the presence of the child, and covert coparenting, that is, the way each parent speaks of the other parent to the child. The sample (N = 80) comprised 48 stepfamilies and 32 first‐marriage families with a child between 7 and 13 years old. Overt coparenting was assessed through direct observation in the standardized situation of the PicNic Game. Covert coparenting and child behavior were assessed through mother‐reported questionnaires. Results showed (a) more covert coparenting behaviors in first‐marriage families, (b) no differences in overt coparenting, (c) more child difficulties reported in stepfamilies, (d) less optimal overt coparenting being linked with more difficulties in children in both family structures, and (e) an interaction effect between family structure and coparenting, showing that overt coparenting is linked with child behavior mainly in stepfamilies.     

Predicting Substance Use Patterns Among Rural Adults: The Roles of Mothers,Fathers, and Parenthood

This study examined the role of parenthood and parental influences on substance use patterns for 710 stimulant users age 18–61 living in the rural Midwest and Mid‐south U.S. Longitudinal growth analyses showed that a maternal history of drug use was associated with increased baseline drug use severity, lesser declines in severity, and greater plateau of drug use severity over time. Parental conflict was associated with lesser declines in drug use severity, and drug use severity declined more steeply for participants who were themselves parents. Participants with two parents having a history of alcohol use had a greater baseline severity of alcohol use, with paternal history of drug use associated with lower baseline alcohol use severity. These findings demonstrate the importance of identifying parental influences in evaluating adult substance use, and point to the inclusion of parents in efforts to prevent and treat substance use disorders.
