Aging and the visual, haptic, and cross-modal perception of natural object shape

One hundred observers participated in two experiments designed to investigate aging and the perception of natural object shape. In the experiments, younger and older observers performed either a same/different shape discrimination task (experiment 1) or a cross-modal matching task (experiment 2). Quantitative effects of age were found in both experiments. The effect of age in experiment 1 was limited to cross-modal shape discrimination: there was no effect of age upon unimodal (ie within a single perceptual modality) shape discrimination. The effect of age in experiment 2 was eliminated when the older observers were either given an unlimited amount of time to perform the task or when the number of response alternatives was decreased. Overall, the results of the experiments reveal that older observers can effectively perceive 3-D shape from both vision and haptics.     

"Frog, where are you?" Narratives in children with specific language impairment, early focal brain injury, and Williams syndrome

In this cross-population study, we use narratives as a context to investigate language development in children from 4 to 12 years of age from three experimental groups: children with early unilateral focal brain damage (FL; N=52); children with specific language impairment (SLI; N=44); children with Williams syndrome (WMS; N=36), and typically developing controls. We compare the developmental trajectories of these groups in the following domains: morphological errors, use of complex syntax, complexity of narrative structure, and types and frequency of evaluative devices. For the children with early unilateral brain damage, there is initial delay. However, by age 10, they are generally within the normal range of performance for all narrative measures. Interestingly, there are few, if any, side specific differences. Children with SLI, who have no frank neurological damage and show no cognitive impairment demonstrate significantly more delay on all morphosyntactic measures than the FL group. Quantitatively, on morphosyntactic measures, the SLI group clusters with those children with WMS who are moderately retarded. Together these data help us to understand the extent and nature of brain plasticity for language development and those aspects of language and discourse that are dissociable.     

Brief assessment and treatment of pica using differential reinforcement,response interruption and redirection,and competing stimuli

Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non-edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented-CSA (A-CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A-CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people.     

Promoting resilience to depression among couples during pregnancy: The protective functions of intimate relationship satisfaction and self-compassion

Pregnancy, while often marked by joy, may pose considerable risk for depression among parents. Against a backdrop of adverse life events, expectant parents may be even more vulnerable to developing symptoms of depression during the prenatal period. Thus, it is critical to identify sources of resilience that might facilitate a successful transition to parenthood among couples who have a history of adversity. Prior work suggests that interpersonal and intrapersonal factors associated with resilience, such as intimate relationship satisfaction and self-compassion (i.e., self-kindness, common humanity, and mindfulness), have the potential to attenuate prenatal depression among couples with a history of stressful life experiences. We tested this possibility in a sample of 159 couples navigating pregnancy. As predicted, a greater number of prior stressful life experiences was associated with increased depression symptom severity for both mothers and fathers. However, moderation analyses revealed the positive link between cumulative stressful life experiences and depression symptom severity was attenuated among mothers who reported greater self-compassion in the form of feelings of common humanity, and fathers who reported higher levels of intimate relationship satisfaction and self-compassion in the form of mindfulness. Findings suggest enhancing intimate relationship satisfaction and self-compassion among expectant couples may be valuable in attenuating prenatal depression among those with a greater history of adversity.     

Science Anxiety as a Function of Gender and Experience

This study examined the influence of gender and various background factors on science anxiety. Students (50 women, 37 men) took the Science Anxiety Scale (Mallow, 1994), provided information about high school and college academic accomplishments, described gender-role stereotyping in the home, and evaluated their science teachers and science experiences. Most participants were Caucasian and from an upper-middle class background. Women were not uniformly more science anxious and had a relatively similar science background to men, although they had higher science grades in high school and did report less stringent sex-role socialization in the home. However, students with high science anxiety took fewer science courses in college, had lower SAT-Q scores, and reported that their high school science teachers were not helpful. The findings regarding gender- and anxiety-linked differences are discussed in terms of women's and men's differential interpretations of their abilities, the influence of parental gender typing on pursuit of science, and the gender-appropriateness of studying science.     

A Multifaceted and Dyadic Examination of Intimate Relationship Quality during Pregnancy: Implications for Global Relationship Satisfaction

Understanding how couples navigate and negotiate the challenges and demands of pregnancy has important implications for family health. The aim of this study was to apply a multidimensional model of intimate relationship quality in a sample of 154 pregnant, cohabitating couples, to investigate the association between a range of intimate relationship processes (i.e., emotional intimacy, conflict management, sexual quality, received respect and acceptance, and received support) and the global relationship satisfaction of each partner. Semistructured clinical interviews were administered to each partner assessing multiple qualities of the relationship, and participants completed home surveys of global relationship satisfaction each day for 14 days. Results demonstrated that multiple dimensions of the intimate relationship were associated with greater relationship satisfaction. Some processes (e.g., degree of emotional intimacy and closeness, conflict management) had larger effects on relationship satisfaction than others (e.g., quality of the sexual relationship). Furthermore, some processes were more important for maternal than paternal satisfaction (e.g., emotional intimacy, support, respect). Finally, results varied, to some degree, as a function of whether parents were transitioning to parenthood for the first time. We discuss the implications of adopting a multidimensional approach to studying the specific relationship processes associated with global relationship satisfaction and present implications for clinicians working with couples navigating the transition into parenthood.

Observing mother-child relationships across generations: boundary patterns,attachment, and the transmission of caregiving

Grounded in both attachment and family systems theories, this study is one of the first to examine how relationship patterns observed in mothers' current relationships with their own mothers are recreated in their relationships with their infants. Mostly white, middle-class families (N = 55), including maternal grandmothers, mothers, and infants, were observed when infants were 6, 9, and 18 months old. At 6 months, mothers and grandmothers completed self-report assessments and worked together on discussion tasks. These interactions were coded using the Boundary Assessment Coding System, developed for the present study, which assessed three relational patterns: disengagement, balance, and entanglement. At 9 months, mothers were rated on sensitivity and intrusiveness while playing with and feeding their infants; and, at 18 months, infant-mother attachment was assessed using the Strange Situation. Multiple regression analyses revealed, as predicted, that mothers who remembered being accepted by their mothers as children and who were in highly balanced relationships with their own mothers currently were more sensitive and less intrusive with their 9-month-old infants. Further, discriminant function analyses indicated that memories of acceptance, high levels of balance, and low levels of disengagement differentiated secure from insecure attachment, whereas memories of overprotection and high levels of entanglement distinguished resistant from secure and avoidant attachment. Discussion focuses on the theoretical hypothesis that mothers internalize relationship strategies experienced with their own caregivers and recreate these patterns with their infants.     

Non-pharmacologic Interventions for CFS: A Randomized Trial

Non-pharmacological behavioral treatments for CFS have been suggested as promising. These trials have tested protocols composed of behavioral, cognitive and cognitive–behavioral interventions but there have been few efforts to differentially evaluate their outcomes. The primary purpose of the current study was to evaluate the effectiveness of nurse delivered non-pharmacologic interventions. In the present study, 114 participants diagnosed with CFS were randomly assigned to four 6-month interventions. The interventions were: cognitive–behavior therapy, cognitive therapy, anaerobic activity, and a relaxation control group. The study found that these interventions led to increases in several areas of functioning, with more consistent changes occurring among those participants in the cognitive condition. For the 25 variables in this study, significant change occurred for 28%, 20%, 16%, and 12% of the variables for the cognitive, cognitive behavior therapy, anaerobic activity, and relaxation conditions, respectively. However, the majority of participants continued to be diagnosed with CFS following the treatment trial. Implications of these findings are discussed.     

Theoretical Models of Affectionate Versus Affectionless Control in Anxious Families: A Critical Examination Based on Observations of Parent–Child Interactions

Psychosocial theories focused on the intrafamilial transmission of anxiety often concentrate on specific parenting behaviors that increase risk of anxiety disorders in children. Two such theories—affectionate versus affectionless control—both implicate parenting, although differently, in the pathogenesis of childhood anxiety. The present article reviews observational studies that focus on interactions between parents and children in anxious families in order to examine critically each of these two models. We divide these observational studies into two groups: those that seek to characterize the behavior of anxious parents (top-down studies) versus parents of anxious children (bottom-up studies). This approach reveals that there is a consistent relationship between controlling parental behavior in families with anxiety-disordered children as well as a consistent relationship between parental behavior low in warmth and families with anxiety-disordered parents. The present article discusses the implications of the pattern that unfolds from the observational studies of the last decade and provides suggestions for future research in the area.
