Editorial: The role of reasoning in mathematical thinking

ABSTRACT

Research into mathematics often focuses on basic numerical and spatial intuitions, and one key property of numbers: their magnitude. The fact that mathematics is a system of complex relationships that invokes reasoning usually receives less attention. The purpose of this special issue is to highlight the intricate connections between reasoning and mathematics, and to use insights from the reasoning literature to obtain a more complete understanding of the processes that underlie mathematical cognition. The topics that are discussed range from the basic heuristics and biases to the various ways in which complex, effortful reasoning contributes to mathematical cognition, while also considering the role of individual differences in mathematics performance. These investigations are not only important at a theoretical level, but they also have broad and important practical implications, including the possibility to improve classroom practices and educational outcomes, to facilitate people's decision-making, as well as the clear and accessible communication of numerical information.     

Using individual functional channels of interest to study cortical development with fNIRS

Functional near‐infrared spectroscopy (fNIRS) is a noninvasive neuroimaging technique that could be uniquely effective for investigating cortical function in human infants. However, prior efforts have been hampered by the difficulty of aligning arrays of fNIRS optodes placed on the scalp to anatomical or functional regions of underlying cortex. This challenge can be addressed by identifying channels of interest in individual participants, and then testing the reliability of those channels' response profiles in independent data. Using this approach, cortical regions with preferential responses to faces versus scenes, and to scenes versus faces, were observed reliably in both adults and infants. By contrast, standard analysis techniques did not reliably identify significant responses to both categories in either age group. These results reveal scene‐responsive regions, and confirm face‐responsive regions, in preverbal infants. More generally, the analysis approach will be a robust and sensitive tool for future characterization of the early functional development of the human brain.     

A self-determination theory approach to problematic drinking and intimate partner violence

Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression.     

What Makes an Idea Risky? The Relations between Perceptions of Idea Novelty,Usefulness, and Risk

Individuals and organizations frequently tout creative ideas as a desirable goal, and yet, creative ideas are frequently rejected. Creativity researchers have often suggested that creative ideas are rejected because they are perceived as riskier due to their inherent novelty or originality. Although this assumption is prevalent, we are unaware of any empirical research directly examining the relations between perceptions of novelty and risk. We provide an empirical test of this assumption in two studies in which participants rate the novelty, usefulness, and riskiness of ideas. Across both studies, we find consistent support for the idea that usefulness, rather than novelty, has the strongest relation with risk perceptions. We also find some evidence that novelty and usefulness interact to predict perceptions of risk. Additionally, in Study 2, we find that usefulness has the strongest relation with willingness to invest and buy a product. The findings of this study suggest that the bias against creativity may be driven by the perceived usefulness of an idea, rather than its novelty, such that ideas with lower usefulness are perceived to be riskier.     

Student Healthcare Clinicians' Illness Narratives: Professional Identity Development and Relational Practice

ABSTRACT

In this qualitative, grounded theory study we examine how the intersection of self-reflection, illness narratives and perceived messages of professional identity inform care provided by medical, nursing, and medical family therapy students to patients and families. We discovered four common challenges students faced navigating personal experiences of illness and connecting to patients: 1) discrepancies between ideal and lived experiences, 2) challenges of healthcare work and culture, 3) navigating power and hierarchy, and 4) developing a shell of privacy. Discussion and implications include interdisciplinary training and collaboration and the unique role of medical family therapists in healthcare.     

Unpacking the Blockers: Understanding Perceptions and Social Constraints of Health Communication in Hereditary Breast Ovarian Cancer (HBOC) Susceptibility Families

Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those who are perceived by study participants as health information gatherers, disseminators, and blockers within families with Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23–56 years, enrolled in a Breast Imaging Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational Map (CEGRM). Purposive sampling ensured that participants varied according to numbers of participating family members e.g., ranging from 1 to 6. Eighty-nine women from 42 families (1–8 relatives/family) participated. They collectively designated 65 blockers, both male and female. Situational factors, beliefs, attitudes and cultural traditions, privacy and protectiveness comprised perceived reasons for blocking intra-family health communications. Longitudinal data collected over 4 years showed families where blocking behavior was universally recognized and stable over time, as well as other families where blocking was less consistent. Self-blocking was observed among a significant minority of participating women. Blocking of health communications among family members with HBOC was variable, complex, and multifaceted. The reasons for blocking were heterogeneous; duration of the blocking appeared to depend on the reasons for blocking. Blocking often seemed to involve bi-directional feedback loops, in keeping with Lepore’s Social Constraints and Modulation Theory. Privacy and protectiveness predominated as explanations for long-term blocking.     

Thin,Sexy Women and Strong,Muscular Men: Grade-School Children's Responses to Objectified Images of Women and Men

There are data that show that women are objectified in the media, that girls and women experience a high rate of body dissatisfaction and eating problems, and that exposure to objectified media images of women is related to the experience of self-objectification and body shame among women. Media images of women promote a thin, sexy ideal. The objectification of men in the media has increased, perhaps promoting a “drive for muscularity” among boys. In the present study grade-school girls and boys ages 6 through 12 were shown four pictures of objectified images of women and men, respectively, and asked about their responses to the pictures. Although girls and boys responded equally positively to the objectified images of the people of their gender, girls showed a more consistent response to the pictures. Further, there were stronger relationships between girls' responses to the pictures, awareness and internalization of media images, and body esteem. Girls who consistently showed a rejection response to the pictures had higher body esteem than those girls who were uncertain about how to respond to the pictures. It was concluded that, perhaps due to cultural images and cultural pressures, girls more readily develop a consistent response to objectified images of women (than boys do to objectified images of men) that relates to their feelings about their own bodies.     

Laboratory analogue investigation of defusion and reappraisal strategies in the context of symbolically generalized avoidance

The present study examined and compared the effects of 2 analogues of cognitive treatments—cognitive defusion and cognitive reappraisal—on symbolically generalized avoidance established using a basic behavioral laboratory paradigm. This back‐translation design contributes to the development and validation of principle‐based definitions of the applied constructs of defusion and reappraisal. Eighty‐eight participants first underwent basic laboratory procedures designed to establish symbolically generalized avoidance in response to an arbitrary stimulus (a nonsense word). Participants were then randomized to defusion, reappraisal, or control conditions. The response variables were (a) equivalence responding—indicative of the trained relational network and analogous to the cognitive content responsible for symbolic generalization—and (b) avoidance—the behavioral impact of symbolic generalization. A between‐groups analysis revealed that defusion and reappraisal significantly increased the odds of nonavoidance responding. Discrete‐time survival mediation analyses provided preliminary support for the classification of defusion as a functional context intervention and reappraisal as a relational context intervention.
