Ordinary variations in maternal caregiving influence human infants' stress reactivity

ABSTRACT— We sought to extend earlier work by examining whether there are ordinary variations in human maternal caregiving behavior (MCB) that are related to stress reactivity in infants. We observed 185 mother-infant dyads and used standard coding systems to identify variations in caregiving behavior. We then created two extreme groups and found that infants receiving low-quality MCB showed more fearfulness, less positive joint attention, and greater right frontal electroencephalographic asymmetry than infants receiving high-quality MCB. Group differences in stress reactivity were not a result of measured infant temperament. However, infants receiving low-quality MCB manifested significantly more negative affect during caregiving activities than did infants receiving high-quality MCB. The results suggest that ordinary variations in MCB may influence the expression of neural systems involved in stress reactivity in human infants.     

Building Bridges Across Differences to Meet Social Action Goals: Being and Creating Allies Among People of Color

Although challenges of anti-racist work are most commonly framed in relation to White people and People of Color, there are significant challenges involved in creating allies across minority racial groups. This article describes our experiences within a community organization aimed at training anti-racist culturally sensitive K-12 educators. As Asian American and Native American facilitators within a group of facilitators of color who were predominantly Black, we describe our experiences of relative marginalization and our (mostly failed) attempts to create change within the organization to be more inclusive of the perspectives, experiences, and needs of non-Black people/students of color. We contextualize these experienced conflicts in relation to race hierarchies, the “divide and conquer strategy” and the maintenance of White privilege. We offer reflections for how racial minorities engaged in anti-racist education could be better allies and how organizations might better foster environments that contribute to the creation of these alliances.

Deconstructing therapy outcome measurement with Rasch analysis of a measure of general clinical distress: the Symptom Checklist-90-Revised

Rasch analysis was used to illustrate the usefulness of item-level analyses for evaluating a common therapy outcome measure of general clinical distress, the Symptom Checklist-90-Revised (SCL-90-R; Derogatis, 1994). Using complementary therapy research samples, the instrument's 5-point rating scale was found to exceed clients' ability to make reliable discriminations and could be improved by collapsing it into a 3-point version (combining scale points 1 with 2 and 3 with 4). This revision, in addition to removing 3 misfitting items, increased person separation from 4.90 to 5.07 and item separation from 7.76 to 8.52 (resulting in alphas of .96 and .99, respectively). Some SCL-90-R subscales had low internal consistency reliabilities; SCL-90-R items can be used to define one factor of general clinical distress that is generally stable across both samples, with two small residual factors.     

Children's printed word database: Continuities and changes over time in children's early reading vocabulary

In this paper we introduce a comprehensive database of the vocabulary in reading materials used by 5 – 9 year old children in the UK. The database is available on‐line http:www.essex.ac.ukpsychologycpwd and allows researchers into early reading development the possibility of rigorous control over critical characteristics of experimental stimuli such as word frequency, regularity and length, frequency of grapheme‐phoneme correspondences, orthographic and phonological neighbourhoods etc. The on‐line database is also a resource that can be used by practitioners with interests in literacy development and literacy instruction. It can be used to obtain characteristics for a user‐generated list of words, or else to generate a list of words according to constraints specified by the user. Here we present an overview of the construction of the database, the materials entered into it, the survey of schools by which we obtained information about the books that were most likely to be used by children in each age group, and the search features available on the database website. We also discuss certain characteristics of the Vocabulary itself and compare these with those reported in an earlier non‐representative database reported in Stuart, Dixon, Masterson and Gray (2003). We then present a detailed analysis of the characteristics of Vocabulary in books used in the Reception year, against the background of recent recommendations for change in the early teaching of reading. Finally, we present data showing that the database is indeed already proving a useful resource for both practitioners and researchers.     

Visuospatial tasks suppress craving for cigarettes

The Elaborated Intrusion (EI) theory of desire posits that visual imagery plays a key role in craving. We report a series of experiments testing this hypothesis in a drug addiction context. Experiment 1 showed that a mental visual imagery task with neutral content reduced cigarette craving in abstaining smokers, but that an equivalent auditory task did not. The effect of visual imagery was replicated in Experiment 2, which also showed comparable effects of non-imagery visual working memory interference. Experiment 3 showed that the benefit of visual over auditory interference was not dependent upon imagery being used to induce craving. Experiment 4 compared a visuomotor task, making shapes from modeling clay, with a verbal task (counting back from 100), and again showed a benefit of the visual over the non-visual task.We conclude that visual imagery supports craving for cigarettes. Competing imagery or visual working memory tasks may help tackle craving in smokers trying to quit.     

Separation of Religion and State and Secularism in Theory and in Practice

Abstract

This study examines whether states follow the religion policies they declare in their constitutions. It identifies four types of policies which officially seek to limit religion's role in government: absolute separation of religion and state (SRAS); neutral political concern; exclusion of ideals; and secularism–laicism. I determine whether states follow these policies using the religion and state (RAS) dataset and compare this to constitutional declarations that the state is secular and declarations of separation of religion and state. The results show that a majority of states which make both types of declaration do not follow these policies based on any of the four standards used in this study. However, the presence and wording of these clauses are correlated with state religion policy.     

Phonological similarity and the irrelevant speech effect: Implications for models of short-term verbal memory

Three experiments studied the interaction between irrelevant speech and phonological similarity within both the remembered and the irrelevant auditory material. Phonological similarity within the remembered list impaired performance in both baseline and irrelevant speech conditions, whereas phonological similarity between the remembered and ignored irrelevant items did not influence performance. Although there was a tendency for similarity within the irrelevant items to reduce interference, this proved to be a less robust finding. Implications for the theoretical interpretation of the irrelevant speech effect are discussed.     

Determinants of the vividness of visual imagery: The effects of delayed recall,stimulus affect and individual differences

This study investigated the influence of emotion on vividness of imagery. A total of 80 undergraduate participants saw 25 pictures from the International Affective Picture System, representing different dimensions of valence and arousal. They rated each stimulus for valence, arousal, and emotionality. Each stimulus was then presented again, and participants formed an image of it, rating the image for vividness, valence, arousal, and emotionality. During a 15‐minute retention interval, participants completed several individual differences questionnaires. They then recalled each image from a verbal prompt and re‐rated its quality. Slides rated as extremely valenced and highly arousing were more vividly imaged than neutral slides. Low mood was also associated with more vivid imagery. The influence of stimulus variables was greater in the immediate imagery phase; that of individual differences tended to be greater in the delayed imagery phase. Of 29 participants, 7 reported intrusive memories of highly unpleasant stimuli at 1 year follow‐up.     

Learning Under Conditions of Action Information Feedback

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied.     

Physical Attractiveness and Popularity: The Mediating Role of Self-Perception

Subjective ratings of physical attractiveness were compared with objective ratings of attractiveness in the prediction of popularity. The relationships between Harter's (1979) Perceived Competency Scale for Children (PCSC) and both popularity and physical attractiveness were also examined. Fifty-three third-grade and 54 fifth-grade children were tested on the Harter scales and on a new 7-item scale of self-perceived attractiveness. Objective attractiveness ratings were provided by 30 other children of the same grades and sex. Popularity was assessed by sociometric nominations and ratings. The results replicated the moderate relationship of objective attractiveness and popularity found in prior studies. Self-perceived attractiveness was unrelated to popularity in third-grade children but was significantly related at the fifth-grade level. Subjective and objective attractiveness were inversely related at the third-grade level but were positively related in fifth graders. Objective attractiveness was unrelated to self-esteem at either grade level but subjective attractiveness predicted self-esteem for all the children.
