Parental Separation and Children's Behavioral/Emotional Problems: The Impact of Parental Representations and Family Conflict

In this longitudinal study, we examine whether the effect of parental separation on kindergarten children's behavioral/emotional problems varies according to the level of family conflict, and children's parental representations. One hundred and eighty seven children were assessed at ages 5 and 6. Family conflict was assessed using parents' ratings. Children's parental representations were assessed using a story-stem task. A multiinformant approach (parent, teacher, child) was employed to assess children's behavioral/emotional problems. Bivariate results showed that separation, family conflict, and negative parental representations were associated with children's behavioral/emotional problems. However, in multivariate analyses, when controlling for gender and symptoms at age 5, we found that children of separated parents who showed negative parental representations had a significantly greater increase in conduct problems between 5 and 6 than all other children. In terms of emotional symptoms and hyperactivity, symptoms at 5 and (for hyperactivity only) gender were the only predictors for symptoms 1 year later. Our results suggest that kindergarten children's representations of parent-child relationships moderate the impact of parental separation on the development of conduct problems, and underline play and narration as a possible route to access the thoughts and feelings of young children faced with parental separation.     

Drunk,but not blind: The effects of alcohol intoxication on change blindness

Alcohol use has long been assumed to alter cognition via attentional processes. To better understand the cognitive consequences of intoxication, the present study tested the effects of moderate intoxication (average BAC between .071 and .082) on attentional processing using complex working memory capacity (WMC) span tasks and a change blindness task. Intoxicated and sober participants were matched on baseline WMC performance, and intoxication significantly decreased performance on the complex span tasks. Surprisingly, intoxication improved performance on the change blindness task. The results are interpreted as evidence that intoxication decreases attentional control, causing either a shift towards more passive processing and/or a more diffuse attentional state. This may result in decreased performance on tasks where attentional control or focus are required, but may actually facilitate performance in some contexts.     

Differentiation of Adolescent Activity Participation

The sex typing or lack of it among 133 adolescent activities was investigated. Twenty-seven percent (32) of the activities on an Adolescent Activity Questionnaire showed very clear participation differences for male and female adolescents (11 to 18 years old). The initial two factors extracted in a principal components factor analysis were easily interpreted as feminine and masculine activities. Discriminant function analysis of 15 items from the first three factors yielded an 8-item function on the basis of which every sample member was correctly classified as male or female. Masculine activities included more sports-related activities and activities dealing with mechanics and building, whereas feminine activities were domestic in nature and included more sedentary activities (e.g., reading, writing in diaries).     

Hindsight bias in insight and mathematical problem solving: Evidence of different reconstruction mechanisms for metacognitive versus situational judgments

This article presents two experiments that used insight and mathematical problems to investigate whether different factors would affect hindsight bias on metacognitive and situational judgments. In both studies, participants initially rated their likelihood of solving each problem within a certain amount of time (metacognitive judgments) and rated the importance of each component of the problem for finding the solution (situational judgments). Next, participants attempted to solve each problem. In Experiment 1, all participants were given solution feedback information, but in Experiment 2, participants were not given any solution feedback. After 1 week, participants were asked to recall their original judgments. Hindsight bias was assessed by comparing the initial with the final ratings. Insight problems and math problems showed different patterns of hindsight bias effects on the metacognitive and situational judgments. The results suggest that two competing models of hindsight effects are actually complementary explanations for judgment reconstruction on different types of judgment tasks.     

Neuroanatomical distribution of five semantic components of verbs: evidence from fMRI

The Simulation Framework, also known as the Embodied Cognition Framework, maintains that conceptual knowledge is grounded in sensorimotor systems. To test several predictions that this theory makes about the neural substrates of verb meanings, we used functional magnetic resonance imaging (fMRI) to scan subjects' brains while they made semantic judgments involving five classes of verbs-specifically, Running verbs (e.g., run, jog, walk), Speaking verbs (e.g., shout, mumble, whisper), Hitting verbs (e.g., hit, poke, jab), Cutting verbs (e.g., cut, slice, hack), and Change of State verbs (e.g., shatter, smash, crack). These classes were selected because they vary with respect to the presence or absence of five distinct semantic components-specifically, ACTION, MOTION, CONTACT, CHANGE OF STATE, and TOOL USE. Based on the Simulation Framework, we hypothesized that the ACTION component depends on the primary motor and premotor cortices, that the MOTION component depends on the posterolateral temporal cortex, that the CONTACT component depends on the intraparietal sulcus and inferior parietal lobule, that the CHANGE OF STATE component depends on the ventral temporal cortex, and that the TOOL USE component depends on a distributed network of temporal, parietal, and frontal regions. Virtually all of the predictions were confirmed. Taken together, these findings support the Simulation Framework and extend our understanding of the neuroanatomical distribution of different aspects of verb meaning.     

Extreme Values of Maternal Serum Analytes in Second Trimester Screening: Looking Beyond Trisomy and NTD’s

Second trimester maternal serum screening can identify high risk pregnancies and fetuses at risk for birth defects (in addition to those in the standard interpretation). The purpose of this study was to quantify such risks to improve counseling. We compared outcomes of 692 pregnancies that had abnormal levels of at least one analyte with a cohort of 713 pregnancies with normal analytes. Increased risks include: demise with high AFP and low uE3; intrauterine growth restriction with high AFP, high and low hCG, and low uE3; placental abnormalities with high AFP; fetal stress with high AFP and high hCG. Birth defects are increased with high AFP, high hCG, and low hCG. When two or more analytes are abnormal, 46% have a poor outcome. Abnormal levels of maternal serum analytes provide information in addition to the risks for neural tube defects, Down syndrome, and trisomy 18. This information is important for counseling and pregnancy management.     

Effects of titles on the processing of text and lexically ambiguous words: Evidence from eye movements

Providing titles for passages improves the comprehension and memorability of text. Titles have generally been thought to facilitate comprehension at later stages of processing. Consistent with prior research, we found that passages presented with titles were better recalled than those without titles. Furthermore, in Experiment 1, the presence of titles led to fewer regressive eye movements, shorter end-of-sentence reading times, and shorter fixation times on target nouns. Experiments 2 and 3, using ambiguous target words, indicated that except when a very infrequent sense of a word is required, titles provide a strong enough context to allow for ambiguous words to be processed as quickly as control words. The results of the three experiments suggest that titles affect processing at both integrative and lexical stages of reading.     

Disease controllability moderates the effect of coping efficacy on positive affect

Objective: This study aims to test experimentally whether coping strategies (approach- vs. avoidance-oriented coping) have differential effects under conditions of high or low stressor controllability.

Design: Undergraduates (62 women, 30 men) participated in a 2 × 2 experimental study where they were introduced to a fictitious disease (tisomerase enzyme deficiency) said to be either controllable or uncontrollable and an approach- or avoidance-oriented coping behaviour induction.

Main Outcome Measures: Changes in positive and negative affect.

Results: A significant disease control x coping interaction on positive affect (f² = .07, p = .011) revealed that approach-coping condition participants had higher positive affect than avoidance-coping condition participants when disease control was high (d = .94, p = .003), but not when it was low (d = .11, p = .93). The experimental conditions did not significantly influence negative affect.

Conclusion: Results demonstrate that disease control moderates the salubrious effects of approach-oriented coping on positive affect. For controllable, but not uncontrollable, health stressors, promoting problem-focused approach-oriented coping strategies may be recommended.
