Attaching meaning to the number words: contributions of the object tracking and approximate number systems

Children's understanding of the quantities represented by number words (i.e., cardinality) is a surprisingly protracted but foundational step in their learning of formal mathematics. The development of cardinal knowledge is related to one or two core, inherent systems – the approximate number system (ANS) and the object tracking system (OTS) – but whether these systems act alone, in concert, or antagonistically is debated. Longitudinal assessments of 198 preschool children on OTS, ANS, and cardinality tasks enabled testing of two single‐mechanism (ANS‐only and OTS‐only) and two dual‐mechanism models, controlling for intelligence, executive functions, preliteracy skills, and demographic factors. Measures of both OTS and ANS predicted cardinal knowledge in concert early in the school year, inconsistent with single‐mechanism models. The ANS but not the OTS predicted cardinal knowledge later in the school year as well the acquisition of the cardinal principle, a critical shift in cardinal understanding. The results support a Merge model, whereby both systems initially contribute to children's early mapping of number words to cardinal value, but the role of the OTS diminishes over time while that of the ANS continues to support cardinal knowledge as children come to understand the counting principles.     

Present but invisible: Physical obscurity fosters social disconnection

Research suggests that we feel invisible and disconnected when others avoid our gaze. In three studies, we examine whether similar feelings may arise when others are unable to meet our gaze—when they are unaware of our presence altogether. We posit that feelings of loneliness and disconnection can arise when others are unable to sense one's physical presence. To test whether invisibility engenders loneliness, we primed participants with the invisibility construct (Studies 1 and 2) and manipulated actual visibility (Study 3) prior to assessing feelings of loneliness and isolation. Results revealed that being present, but unseen, is sufficient to induce loneliness. Findings are related to the ostracism and intersectional invisibility literatures, and the social costs of physical obscurity are discussed.     

The effects of independent and interdependent self-construals on reactions to transgressions: distinguishing between guilt and shame

The self-conscious emotions of guilt and shame are commonly distinguished by the self-reflective processes that foster these emotions. Distinctions based on resulting behavioral reactions, however, have been questioned in recent studies highlighting the role of different self-motivations. The current work draws on the self-construal literature to further clarify the antecedents and consequences of guilt and shame. We hypothesized that conceptualizing the self as independent from (vs. interdependent with) others fosters behavior-related (vs. self-related) cognitions typically associated with guilt (vs. shame). Additionally, we predicted that the deleterious consequences of shame for externalizing blame are more characteristic of independent (vs. interdependent) selves. These hypotheses were supported across two studies that measured (Study 1) and primed (Study 2) self-construals. Overall, our results suggest that the cognitive reactions associated with guilt and shame are differently encouraged by independent and interdependent self-construals.     

Onset of Illness and Developmental Factors in Social Anxiety Disorder: Preliminary Findings from a Retrospective Interview

Although many advances have been made in the treatment of Social Anxiety Disorder (SAD), less is known about its onset and factors related to its course and severity. The current study aimed to investigate developmental factors (e.g., onset of illness, behavioral inhibition, socially traumatic experiences) that research has suggested are related to the course and severity of SAD in a sample of adults diagnosed with generalized SAD. Results showed behavioral inhibition to be the only consistent predictor of current severity. Results for age of onset were consistent with previous studies suggesting an early childhood and later adolescent pattern. In addition, an earlier age of onset negatively impacted improvement in cognitive behavior therapy for SAD, but no other developmental factors were related to treatment outcome. Future research using longitudinal designs and multiple informants is needed to confirm findings from retrospective reports.

Positive and negative sources of emotional arousal enhance long-term word-list retention when induced as long as 30 min after learning

The consolidation of newly formed memories occurs slowly, allowing memories to be altered by experience for some time after their formation. Various treatments, including arousal, can modulate memory consolidation when given soon after learning, but the degree of time-dependency of these treatments in humans has not been studied. Thus, 212 participants learned a word list, which was followed by either a positively or negatively valenced arousing video clip (i.e., comedy or surgery, respectively) after delays of 0, 10, 30 or 45 min. Arousal of either valence induced up to 30 min after learning, but not after 45 min, significantly enhanced one-week retrieval. The findings support (1) the time-dependency of memory modulation in humans and (2) other studies that suggest that it is the degree of arousal, rather than valence that modulates memory. Important implications for developing memory intervention strategies and for preserving and validating witness testimony are discussed.     

Continuity in social cognition from infancy to childhood

Research examining the development of social cognition has largely been divided into two areas: infant perception of intentional agents, and preschoolers’ understanding of others’ mental states and beliefs (theory of mind). Many researchers have suggested that there is continuity in social cognitive development such that the abilities observed in infancy are related to later preschool ability, yet little empirical evidence exists for this claim. Here, we present preliminary evidence that capacities specific to the social domain contribute to performance in social cognition tasks both during infancy and in early childhood. Specifically, looking time patterns in an infant social cognition task correlated with preschool theory of mind; however, no such relationship was found for infants in a nonsocial cognition task.     

The Relationship between Cultural Values and Political Ideology, and the Role of Political Knowledge

Cultural theory maintains that four worldviews—egalitarianism, individualism, hierarchicalism, and fatalism—can be used to describe people and societies. We examine survey measures of two of those worldviews—egalitarianism and individualism—to understand their relationship with belief systems. Contrary to what one might expect based on the cultural theory literature, we find that people with low levels of political knowledge seem not to have coherent worldviews regarding these issues. In contrast, people with high levels of political knowledge respond to egalitarianism and individualism questions as if they were opposite ends of a single, liberal-conservative continuum, rather than two of four distinct worldviews. We conclude that cultural theory researchers should take account of the influence of political knowledge whenever they investigate worldviews.     

The Low Risk Research Ethics Application Process at CQUniversity Australia

The CQUniversity Australia Human Research Ethics Committee (HREC) is a human ethics research committee registered under the auspices of the National Health and Medical Research Council. In 2009 an external review of CQUniversity Australia’s HREC policies and procedures recommended that a low risk research process be available to the institution’s researchers. Subsequently, in 2010 the Human Research Ethics Committee Low Risk Application Procedure came into operation. This paper examines the applications made under the Human Research Ethics Committee Low Risk Application Procedure during the course of 2010 and 2011. The paper contributes to the literature analyzing the decision-making processes of research review committees through an analysis of the quantitative data relating to the low risk research applications made and through discourse analysis of the qualitative data represented by the assessment comments of the members of the Committee.     

Pregnancy as an Opportunity for Trauma-Intervention Among Women Who Are Addicted to Substances

Victims of violence come from various backgrounds; however, the intersection of gender combined with poverty, belonging to a racial minority, [dis]ability, and youth, put women at greater risk for experiencing violence and trauma. Many of these features are also high-risk markers for women who experience addictions to substances. Considering the risk factors and prevalence of violence and addictions experienced by young women, it is important to consider the comorbidity of complex trauma and substance use disorder and their combined effects on women’s reproductive health. The experience of pregnancy, combined with the experience of past trauma and addictions, presents a complex and compelling situation in which women struggle to balance their intentions to maintain a healthy pregnancy, with the drive to use substances as a way to cope with unresolved past traumatic experiences. By reviewing the literature regarding addictions, pregnancy, and complex trauma, this article aims to demonstrate that pregnancy presents a unique opportunity for trauma intervention among addicted women, and to establish how a missed opportunity for trauma-focused intervention can contribute to intergenerational trauma, creating a cycle of harm for women and their children.
