Prediction of toddlers’ expressive language from maternal sensitivity and toddlers’ anger expressions: A developmental perspective

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.     

A comparison of human performance in figural and navigational versions of the traveling salesman problem

Performance on a typical pen-and-paper (figural) version of the Traveling Salesman Problem was compared to performance on a room-sized navigational version of the same task. Nine configurations were designed to examine the use of the nearest-neighbor (NN), cluster approach, and convex-hull strategies. Performance decreased with an increasing number of nodes internal to the hull, and improved when the NN strategy produced the optimal path. There was no overall difference in performance between figural and navigational task modalities. However, there was an interaction between modality and configuration, with evidence that participants relied more heavily on the NN strategy in the figural condition. Our results suggest that participants employed similar, but not identical, strategies when solving figural and navigational versions of the problem. Surprisingly, there was no evidence that participants favored global strategies in the figural version and local strategies in the navigational version.     

Symptoms,impairment and illness intrusiveness–their relationship with depression in women with CFS/ME

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is an illness in which physiological and psychological factors are believed to interact to cause and maintain CFS/ME in an individual predisposed to it. The various symptoms and impairments associated with CFS/ME have a large impact on quality of life. The purpose of the present study was to identify the extent to which the core symptoms and impairments associated with CFS/ME relate to depression in women with CFS/ME, and to discover whether these relationships were mediated by illness intrusiveness. CFS/ME was found to be a highly intrusive illness, intruding into more life domains and to a greater degree than other illnesses. The effects of both symptoms and impairment on depression were, in part, mediated by illness intrusiveness. Although symptoms severity and impairment had both direct and indirect effects on depression, illness intrusiveness was the strongest predictor of depression.     

Sleep disturbance and emotion dysregulation as transdiagnostic processes in a comorbid sample

Sleep disturbance and emotion dysregulation have been identified as etiologic and maintaining factors for a range of psychopathology and separate literatures support their relationships to anxiety, depression, PTSD, and alcohol dependence (AD) symptom severity. Previous studies have examined these relationships in isolation, failing to account for the high rates of comorbidity among disorders. It is not yet known whether these processes uniquely predict symptom severity in each of these domains. Participants were 220 patients in residential substance abuse treatment, who had experienced a potentially traumatic event and exceeded screening cutoffs for probable PTSD and problematic alcohol use. Controlling for emotion dysregulation and the interrelationships among the outcome variables, insomnia was uniquely associated with anxiety (B = .27, p < .001), depression (B = .25, p < .001), PTSD (B = .22, p < .001), and AD (B = .17, p = .01) symptom severity. Similarly, controlling for insomnia, emotion dysregulation was uniquely associated with anxiety (B = .40, p < .001), depression (B = .47, p < .001), PTSD (B = .38, p < .001), and AD (B = .26, p < .001) symptom severity. Insomnia and emotion dysregulation appear to be transdiagnostic processes uniquely associated with symptom severity across a number of different domains and might be important treatment targets for individuals with PTSD and AD.     

A Foreigner in My Own Country: Forgetting the Heterogeneity of Our National Community

The issues of human cloning and stem cell retrieval are inseparable in circumstances in which the rationale of self-preservation may be invoked as a negative right. I apply this rationale to a hypothetical case in which cloning is necessary to preserve the bodily integrity or life of an individual. Self-preservation as moral integrity is examined in a narrower context, i.e., as applicable to those for whom deliberate termination of embryonic life is morally-problematic. This issue is addressed through comparison with two paradigms commonly used in support of clinical practice: the distinction between letting die and killing, and the permissibility of vital organ retrieval after death. Although these paradigms are questionable in their own right, they offer a rationale by which scientists and clinicians may respect the negative right to moral integrity of those with whom they disagree.     

Pupil diameter measurement errors as a function of gaze direction in corneal reflection eyetrackers

Pupil dilation is a useful, noninvasive technique for measuring the change in cognitive load. Since it is implicit and nonverbal, it is particularly useful with preverbal or nonverbal participants. In cognitive psychology, pupil dilation is most often measured by corneal reflection eye-tracking devices. The present study investigates the effect of gaze position on pupil size estimation by three common eye-tracking systems. The task consisted of a simple object pursuit situation, as a sphere rotated around the display screen. Systematic errors of pupil size estimation were found with all three systems. Implications for task-elicited pupillometry, especially for gaze-contingent studies such as object tracking or reading, are discussed.     

Life Events may Contribute to Family Communication About Cancer Risk Following BRCA1/2 Testing

We assessed whether certain life events contributed to the communication about cancer risk within families who have undergone BRCA1/2 testing. We also explored what type of resources participants would have valued to help in supporting family communication about genetic information. Two hundred and forty-six individuals (218 women, 28 men) who received a BRCA1/2 genetic test result 3 to 10 years earlier (mean of 6.4 years) participated in a telephone interview. Participants were asked about the occurrence of a number of life events (cancer diagnosis, death, uptake of prophylactic surgery, and providing care to a family member with cancer) in their family since their BRCA1/2 test result disclosure and, for each occurrence, whether it fostered family communication about cancer risk. A total of 182 participants (74 %) reported that they or one of their relatives received a cancer diagnosis, 176 (72 %) reported that someone died in their family, and 73 (30 %) stated that they or one of their relatives undertook a prophylactic surgery. During this period, 109 participants (44 %) also provided care for a family member who had cancer. Among participants who reported these life events, family communication was fostered by these events in proportions varying from 50 % (death) to 69 % (cancer diagnosis). Our results indicate that life events may contribute to family communication about cancer risk. Further research is needed to determine whether these events provide a “window of opportunity” to reach family members, address their needs and concerns about cancer, update family cancer history, and introduce genetic counseling and risk assessment.     

Long-Term stress reactions in new immigrants to israel exposed to the chernobyl accident

Abstract

This comparison study examined the relation between presumed level of exposure to the accident at Chernobyl in 1986 to symptoms of post-traumatic stress disorder (PTSD) and other psychological symptoms (depression, somatization, anxiety, obsessive-compulsive style and interpersonal sensitivity), life events and the negative appraisal of the events surrounding the accident. The sample (N = 708) included new immigrants from the former Soviet Union (Confederation of Independent States) who arrived in Israel since 1989 from more exposed areas (n = 137), less exposed (n = 240) and a comparison sample (n = 331) who immigrated from other republics. The exposed groups had higher mean scores on all psychological outcome measures than the comparison group, particularly symptoms of PTSD. Both subsequent stressful life events and a negative, cognitive assessment of events contributed to present psychological distress, independent of exposure.     

An Island in a Sea of Development: An Examination of Place Attachment,Activity Type,and Crowding in an Urban National Park

ABSTRACT

As more people move to urban areas there will be increased pressure on existing green spaces to offer places for recreation, contemplation, historic interpretation, exercise, and nature appreciation. Development and a rise in population has led to too few public recreation sites available in many regions of the world resulting in unsustainable pressure being applied to parks. The objective of this study was to examine how place attachment may be related to type and frequency of park use and management issues regarding crowding. Data for this study were obtained via intercept survey of a random sample of visitors (N = 1088) at a park in the Metro Atlanta area, Georgia. Results suggest that place attachment had a significant relationship with frequency of visits and types of activities that visitors engaged in. There was, however, no significant relation between place attachment and crowding. First-time visitors and less frequent visitors felt most crowded, which may support the idea that the most frequent visitors expect it to be crowded and are, therefore, less sensitive to it. This study sheds light on how visitors to an urban park view their experience while recreating, and may inform policies and regulations that will help mitigate the unique management situations that urban parks present.     

Strengthening encoding via implementation intention formation increases prospective memory commission errors

Prospective memory refers to the ability to remember to execute future intentions (e.g., taking medication with dinner). Although most prior research on prospective memory errors has focused on omission errors (i.e., failures to perform an intention in response to a target cue), there has been a recent surge in research on commission errors, the erroneous performance of a finished intention. Existing studies have examined factors at retrieval that lead to commission errors; the present study extends this research by investigating the impact of encoding strength. We found that relative to standard encoding, implementation intention encoding doubled the risk of commission errors in our laboratory paradigm for both young and older adults. This novel finding demonstrates the impact of encoding strength on commission errors and documents the potential challenges of deactivating the effects of implementation intentions upon completion of a prospective memory task.
