Perceiving Necessity

In many diagrams one seems to perceive necessity – one sees not only that something is so, but that it must be so. That conflicts with a certain empiricism largely taken for granted in contemporary philosophy, which believes perception is not capable of such feats. The reason for this belief is often thought well‐summarized in Hume's maxim: ‘there are no necessary connections between distinct existences’. It is also thought that even if there were such necessities, perception is too passive or localized a faculty to register them. We defend the perception of necessity against such Humeanism, drawing on examples from mathematics.     

The Use of Risk and Need Factors in Forensic Mental Health Decision-Making and the Role of Gender and Index Offense Severity

Canadian legislation makes Review Boards (RBs) responsible for rendering dispositions for individuals found Not Criminally Responsible on account of Mental Disorder (NCRMD) after considering public safety, the mental condition of the accused, and his/her potential for community reintegration. We reviewed 6,743 RB hearings for 1,794 individuals found NCRMD in the three largest Canadian provinces to investigate whether items from two empirically supported risk assessment measures, the Historical Clinical Risk Management-20 and the Violence Risk Appraisal Guide, were considered. Less than half the items were included in expert reports or in RBs' reasons for dispositions, and consideration of these items differed according to gender and index offense severity of the accused. These items included evidence-based risk factors and/or legally specified criteria: mental health, treatment, and criminal history. These results illustrate the gap between research on risk factors and the integration of this evidence into practice. In particular, we recommend the implementation of structured measures to reduce the potential for clinicians to be unduly influenced by gender and offense severity.

WOMEN'S HOSTILITY TOWARD WOMEN

Three studies investigating the self-report correlates of women's hostility toward other women were conducted among a total of 477 college women. In Study 1, hostility toward women was negatively associated with both personal and collective self-esteem and positively associated with hostility toward men, controlling for state anger. In Study 2, hostility toward women was negatively associated with self-efficacy and age and positively associated with emotional dependence on men, but not with self-identification as a feminist or support of the feminist movement. In Study 3, women's hostility toward women was negatively associated with measures of intimacy and life satisfaction and positively associated with acceptance of interpersonal violence. We suggest that women's hostility toward other women not only is an important aspect of women's personal satisfaction, happiness, intimacy, and self-esteem, but also may serve as a barrier to women's progress as a group.     

Intersection crossing considered as intercepting a moving traffic gap: Effects of task and environmental constraints

Safely crossing an intersection requires that drivers actively control their approach to the intersection with respect to characteristics of the flow of incoming traffic. To further our understanding of the perceptual-motor processes involved in this demanding manoeuvre, we designed a driving simulator experiment in which 13 participants actively negotiated intersections by passing through a gap in the train of incoming traffic. Task constraints were manipulated by varying the size of the traffic gap and the initial conditions with respect to the time of arrival of the traffic gap at the intersection. Environment constraints were manipulated by varying the intersection geometry through changes in the angle formed by the crossroads. The results revealed that the task constraints systematically gave rise to continuous and gradual adjustments in approach velocity, initiated well before arriving at the intersection. These functionally appropriate adjustments allowed the drivers to safely cross the intersection, generally just slightly ahead of the center of the traffic gap. Notwithstanding the fact that the geometry of the intersection did not affect the spatiotemporal constraints of the crossing task, approach behavior varied systematically over geometries, suggesting that drivers rely on the traffic gap's bearing angle. Overall, the pattern of results is indicative of a continuous coupling between perception and action, analogous to that observed in locomotor interception tasks.     

Relationship distress in partners of combat veterans: the role of partners' perceptions of posttraumatic stress symptoms

Partners of combat veterans with posttraumatic stress disorder report elevated relationship and psychological distress, but little is known about the mechanisms by which such distress develops. In two separate samples, we examined partners' perceptions of veterans' PTSD symptoms, with a specific focus on the simultaneous associations of partners' distress with their perceptions of veterans' reexperiencing, withdrawal/numbing, and hyperarousal symptom clusters. The first sample consisted of 258 partners of Operation Enduring- and Iraqi Freedom-era veterans who completed questionnaires. The second sample consisted of 465 partners of Vietnam-era veterans who completed interviews as part of the National Vietnam Veterans Readjustment Study. In both samples, path analyses revealed that, when examined simultaneously, partners' perceptions of withdrawal/numbing symptoms were associated with greater distress, but perceptions of reexperiencing symptoms were unrelated to psychological distress and significantly associated with lower levels of relationship distress. Given the cross-sectional nature of the data in both samples, there are multiple plausible interpretations of the results. However, the pattern is consistent with an attributional model of partner distress, whereby partners are less distressed when symptoms are more overtly related to an uncontrollable mental illness. Potential clinical implications are discussed.     

“It's ok — Not everyone can be good at math”: Instructors with an entity theory comfort (and demotivate) students

Can comforting struggling students demotivate them and potentially decrease the pool of students pursuing math-related subjects? In Studies 1–3, instructors holding an entity (fixed) theory of math intelligence more readily judged students to have low ability than those holding an incremental (malleable) theory. Studies 2–3 further revealed that those holding an entity (versus incremental) theory were more likely to both comfort students for low math ability and use “kind” strategies unlikely to promote engagement with the field (e.g., assigning less homework). Next, we explored what this comfort-oriented feedback communicated to students, compared with strategy-oriented and control feedback (Study 4). Students responding to comfort-oriented feedback not only perceived the instructor's entity theory and low expectations, but also reported lowered motivation and lower expectations for their own performance. This research has implications for understanding how pedagogical practices can lock students into low achievement and deplete the math pipeline.     

How Opposites (Should) Attract: Humility as a Virtue for the Strong

This article first examines pervasive present‐day attitudes toward humility (‘The Contemporary Distaste for Humility’) before turning to Thomas Aquinas and Zhu Xi for their more positive treatments of this disposition (‘Thomas Aquinas and Zhu Xi on Humility’). It then considers their ideas about how humility is related to our human limitations (‘Humility Grounded in Our Finite Nature and Knowledge’), before surveying how they think it should be expressed in our relationships with our neighbours (‘Humility in Community’). The article looks at what Thomas and Zhu have to say about excessive pride in rulers (‘Humility and Authority’) before closing in the Conclusion with some thoughts about the viability of humility as a virtue for the strong, and its especial importance in contemporary politics.
