Fostering First Graders’ Fluency With Basic Subtraction and Larger Addition Combinations Via Computer-Assisted Instruction

Achieving fluency with basic subtraction and add-with-8 or -9 combinations is difficult for primary grade children. A 9-month training experiment entailed evaluating the efficacy of software designed to promote such fluency via guided learning of reasoning strategies. Seventy-five eligible first graders were randomly assigned to one of three conditions: guided subtraction (e.g., If 5 + 3 = 8, then 8 – 3 is 5), guided use-a-10 (e.g., If 10 + 7 = 17, then 9 + 7 is 16), or an unguided-practice condition for 30-minute sessions twice a week for 12 weeks. An ANCOVA revealed that at the delayed posttest, the guided-subtraction group outperformed both comparison groups on unpracticed subtraction combinations. Analyses of gains in slow but appropriate use of reasoning and decreases in inefficient strategy use indicated that both types of guided training promoted the learning of a targeted reasoning strategy.     

Ten Year Research Update (2001–2010): Evaluations for Competence to Stand Trial (Adjudicative Competence)

This article reviews and evaluates publications during 2001–2010 with relevance for assessments of competence to stand trial, referred to in this article as adjudicative competence. The review focuses specifically on articles that provide new concepts or data supported by research or case analyses. The studies are reviewed under the following headings: (i) systemic issues, (ii) conceptual guidelines for AC evaluations, (iii) AC assessment methods, (iv) empirical correlates of AC judgments and psycholegal abilities, (v) quality of AC evaluations and reports, (vi) interpretive issues, (vii) special populations (defendants who are elderly, defendants with intellectual disabilities), (viii) AC evaluations of juveniles, and (ix) treatment of incompetent defendants. Suggestions are offered for further research to advance the quality of clinical evaluations of adjudicative competence. Copyright © 2013 John Wiley & Sons, Ltd.     

Assessing Young Children's Number Magnitude Representation: A Comparison Between Novel and Conventional Tasks

Previously, researchers have relied on asking young children to plot a given number on a 0-to-10 number line to assess their mental representation of numbers 1 to 9. However, such a (“conventional”) number-to-position (N-P) task may underestimate the accuracy of young children's magnitude estimates and misrepresent the nature of their number representation. The purpose of this study was to compare young children's performance on the conventional N-P task and a “modified” N-P task that is more consistent with a discrete-quantity view of number and with measures of theoretically related mathematical competencies. Participants (n = 45), ranging in age from 4;0 to 6;0, were administered both versions of the N-P task twice during 4 sessions in 1 of 2 randomly assigned and counterbalanced orders. Between and within conditions, children were significantly more accurate on the modified version than on the conventional task. The results indicate that the conventional task, in particular, may be confusing and that several simple modifications can make it more understandable for young children. However, when performance on theoretically related number tasks is taken into account, both the conventional and the modified N-P tasks appeared to underestimate competence.     

Compounding Vulnerability: Pregnancy and Schizophrenia

The predominant ethical framework for addressing reproductive decisions in the maternal–fetal relationship is respect for the woman's autonomy. However, when a pregnant schizophrenic woman lacks such autonomy, healthcare providers try to both protect her and respect her preferences. By delineating etic (objective) and emic (subjective) perspectives on vulnerability, I argue that options which balance both perspectives are preferable and that acting on etic perspectives to the exclusion of emic considerations is rarely justified. In negotiating perspectives, we balance the etic commitment to protect the vulnerable patient and her fetus from harm with the emic concern to empower a decisionally incapacitated woman. Equilibrium is best achieved by nurturing interdependent relationships that empower and protect the vulnerable woman. The analysis points to the need for better social support for mentally ill patients.     

Evidence for a detrimental relationship between hypertension history, prospective memory, and prefrontal cortex white matter in cognitively normal older adults

Hypertension affects many older adults and is associated with impaired neural and cognitive functioning. We investigated whether a history of hypertension was associated with impairments to prospective memory, which refers to the ability to remember to perform delayed intentions, such as remembering to take medication. Thirty-two cognitively normal older adult participants with or without a history of hypertension (self-reported) performed two laboratory prospective memory tasks, one that relied more strongly on executive control (nonfocal prospective memory) and one that relied more strongly on spontaneous memory retrieval processes (focal prospective memory). We observed hypertension-related impairments for nonfocal, but not focal, prospective memory. To complement our behavioral approach, we conducted a retrospective analysis of available structural magnetic resonance imaging data. Lower white matter volume estimates in the anterior prefrontal cortex were associated with lower nonfocal prospective memory and with a history of hypertension. A history of hypertension may be associated with worsened executive control and lower prefrontal white matter volume. The translational implication is that individuals who must remember to take antihypertensive medications and to monitor their blood pressure at home may be impaired in the executive control process that helps to support these prospective memory behaviors.     

The Relationships Among Grief Experience,Problem-Solving Appraisal,and Depression: An Exploratory Study

Abstract

Research has consistently shown a relationship between problem-solving appraisal and depressive symptoms. This study expands that research by including grief symptomatology as a variable. A college student sample completed the Problem-Solving inventory, the Beck Depression Inventory, and the Revised Grief Experience Inventory. Consistent with hypotheses, those individuals who had experienced the death of a close loved one within the previous 5 years reported significantly higher levels of grief and depression than those who had not experienced such a loss. However, the group that had experienced the death of a close loved one did not report significantly worse problem-solving scores than the group that did not. This study also examined the relationships among problem-solving appraisal, depressive symptoms, and grief symptoms within the subsample that had experienced the loss of a close loved one within the previous 5 years. Consistent with predictions, grief symptoms were associated with depressive symptoms and self-appraised ineffective problem solving. The results of this study extend the research on grief and mourning. Also, the results expand our understanding of the grief process by providing preliminary evidence for the role of problem solving in this process     

Sexual Prejudice among Christian College Students, Denominational Teachings, and Personal Religious Beliefs

Although numerous studies have examined the role of religious tradition and religiosity on attitudes toward lesbian, gay, and bisexual people, the role of endorsement of denominational teachings has largely been overlooked, even though such teachings are often cited to explain study findings. To better understand the complex relationship between religion and sexual prejudice, this study explores the unique contributions of religious tradition, religiosity, and individual endorsement of denominational doctrine about same-sex sexuality in shaping these attitudes. Findings indicate that endorsement of denominational doctrine concerning same-sex sexuality is more influential than religiosity, and that endorsement of denominational doctrine is not simply a proxy for believing that same-sex sexuality is a sin. Implications for future research are discussed.     

Less is more: The effect of multiple implementation intentions targeting unhealthy snacking habits

Implementation intentions have been shown to effectively change counter‐intentional habits. Research has, however, almost solely been concerned with the effectiveness of a single plan. In the present research, we investigated the behavioral and cognitive implications of making multiple implementation intentions targeting unhealthy snacking habits and its underlying processes, linking multiple habitual snacking cues to healthy alternatives. Study 1 revealed that formulating multiple implementation intentions was not effective in decreasing unhealthy snacking, whereas formulating a single plan successfully induced behavior change. By using a lexical decision task in Study 2, it was found that when making a single plan, but not multiple plans, the healthy alternative became cognitively more accessible in response to a critical cue prime than the habitual response. However, when making additional plans in an unrelated domain, the negative effects of making multiple plans were absent. In sum, the current findings suggest that formulating multiple implementation intentions is ineffective when changing unwanted behavior. These reduced effects of multiple implementation intentions do not occur when making the plan but are rather due to interference in the enacting phase of the planning process.

Motor Development During the First Year: A Comparative Study

This investigation of the motor development characteristics of Brazilian infants during the 1st year of postnatal life compared the findings with those of a widely used U.S. sample (N. Bayley, 1993). Analysis of the 12 monthly assessments indicated that Brazilian infants' scores increased with age, with the greatest increase occurring over the first 8 months. As a general comparison, the results are similar to the U.S. patterns of development. However, the Brazilian sample exhibited mean scores significantly lower than the U.S. sample's in the 3rd, 4th, and 5th months. More specific analyses indicated that the difference within these months was on tasks of sitting and grasping. Possible explanations for the differences focus on variations in child-rearing practices and the influence of biological maturation in early movement behaviors.
