VISITING DEAD ANCESTORS: SHAMANS AS INTERPRETERS OF RELIGIOUS TRADITIONS

Abstract. Religious traditions enable ancestors to encourage proper social behavior in their distant descendants. Although traditional myths and rituals can provide basic values, these values must be interpreted in light of the specific circumstances encountered by later generations. In tribal societies the task of interpreting religious traditions falls upon religious leaders known as shamans. Shamans, perhaps universally, are claimed to obtain instructions from dead ancestors on how to deal with social disruptions. This paper argues that a focus on the more exotic aspects of shamanism has kept previous studies from realizing the crucial role of shamans as interpreters of religious traditions.     

LOCAL AND GLOBAL PROCESSES IN VISUAL COMPLETION

In the natural environment, objects are frequently occluded, and people continuously complete partly occluded objects Do local processes or global processes control the completion of partly occluded objects? To answer this question, most previous studies simply asked subjects to draw the completions they "saw" Such drawing tasks are highly subjective, and they provide equivocal results Our studies are the first to use an objective, implicit paradigm (primed matching) to determine the extent to which local or global processes underlie the visual completion of partly occluded objects Our results suggest that global processes dominate perceptual completion, whereas local processes do not play a large role Therefore, local theories of completion, or theories in which local processes dominate, cannot be entirely correct     

Hierarchical structure in perceptual representation

A theoretical framework for perceptual representation is presented which proposes that information is coded in hierarchical networks of nonverbal propositions. The hierarchical structure of the representations implies selective organization: Some subsets of a figure will be encoded as integral, structural units of that figure, while others will not. A context-sensitive metric for the “goodness” of a part within a figure is developed, corresponding to the probability that the subset will be encoded as a structural unit. Converging evidence supporting this position is presented from four different tasks using simple, straight-line figures. The tasks studied are (a) dividing figures into “natural” parts, (b) rating the “goodness” of parts within figures, (c) timed verification of parts within figures, and (d) timed mental synthesis of spatially separated parts into unitary figures. The results are discussed in terms of the proposed theory of representation, the processes that operate on those representations, and the general implications of the data for perceptual theories.     

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.
