Second-Order Characterizable Cardinals and Ordinals

The notions of finite and infinite second-order characterizability of cardinal and ordinal numbers are developed. Several known results for the case of finite characterizability are extended to infinite characterizability, and investigations of the second-order theory of ordinals lead to some observations about the Fraenkel-Carnap question for well-orders and about the relationship between ordinal characterizability and ordinal arithmetic. The broader significance of cardinal characterizability and the relationships between different notions of characterizability are also discussed.

Reliability and Validity of a Brief Life Satisfaction Scale with a High School Sample

This study investigated the psychometric properties of a brief life satisfaction scale, the Brief Multidimensional Students’ Life Satisfaction Scale (Huebner et al., 2004a), with a high school age sample. The results revealed preliminary evidence of internal consistency, two-week test–retest reliability, construct validity, and criterion-related validity for research purposes. Expected demographic effects were also obtained. Overall, the findings suggest that the BMSLSS may provide a useful indicator of adolescent life satisfaction in studies in which brevity of measures is an important consideration.     

'BY LEIBNIZ'S LAW': REMARKS ON A FALLACY

I investigate a form of argument which refers to Leibniz's law as its inference ticket (where 'Leibniz's law' is understood as the thesis that if x = y, then all properties of x are properties of y, and vice versa). Arguments of this form are often used to establish certain categorial distinctions, e.g., a distinction between kinds and properties, or a distinction between processes and events. I show that there can be deficient arguments of this form, and why. I then argue that the interesting philosophical cases of this argument form are unconvincing, since they cannot be seen as clear cases of its unproblematic variety.     

Gender Role Development and Body Image among Male and Female First Year College Students

In the current study we examined associations between gender role development and body image. Male and female first-semester college students (N = 434) who identified as African American, Latino/a American, and European American completed surveys about gendered personality traits (instrumentality/expressivity), gender role attitudes, and aspects of body image (e.g., satisfaction, orientation). Gendered traits were more frequently associated with body image than were gender role attitudes. In particular, individuals who were more instrumental and less inauthentic in their relationships felt more positive about their bodies. Gender role attitudes were also associated with body image, but sometimes in an unexpected direction. These findings highlight the importance of examining multiple components of gender role development and body image in both men and women.An earlier version of this paper was presented at the 2004 Biennial Meeting of the Society for Research on Adolescence, Baltimore, MD. This research was supported by grant R01 HD 41720 from the National Institute of Child Health and Human Development to Eva S. Lefkowitz.     

The cognitive functioning of older adult instrumental musicians and non-musicians

This study examined similarities and differences in the cognitive profiles of older adult instrumental musicians and non-musicians. We compared neuropsychological test scores among older adult non-musicians, low-activity musicians (<10 years of lessons), and high-activity musicians (≥10 years of lessons), controlling for self-reported physical and social activity, years of education, and overall health. Significant differences among groups were found on tasks of visual spatial ability, naming, and executive functioning. No significant differences were found on tests of attention/processing speed, or episodic memory. The current study supports late life cognitive benefits of early musical training, but only in select cognitive domains, including language, executive functioning, and visual spatial ability. The results are discussed in the context of cognitive reserve and aging.     

Internet-Delivered Exposure-Based Cognitive-Behavioral Therapy for Adolescents With Functional Abdominal Pain or Functional Dyspepsia: A Feasibility Study

Functional abdominal pain (FAP) and functional dyspepsia (FD) are common in adolescents and associated with low quality of life. Exposure-based cognitive-behavioral therapy (CBT) is efficient for adult and adolescent irritable bowel syndrome (IBS), but has never been evaluated for adolescent FAP/FD. The aim of this study was to evaluate the feasibility and potential efficacy of a novel disorder-specific Internet-delivered CBT (Internet-CBT) for adolescents with FAP or FD, using an uncontrolled open pilot including 31 adolescents. The Internet-CBT consisted of 10 weekly online modules, which focused mainly on exposure to abdominal symptoms. Parents received modules to help them reduce unhelpful parental behaviors. Participants reported the treatment to be credible, and an overall satisfaction with the treatment. Data attrition rate was low (7%) and adherence to treatment was acceptable. We saw a significant and large effect on the primary outcome, pain intensity, at posttreatment (d = 1.20, p < .001) that was further improved after 6 months (d = 1.69, p < .001). Participants also made significant and large improvements on gastrointestinal symptoms (d = 0.84, p < .001) and quality of life (d = 0.84, p < .001) that were sustained or further improved at follow-up 6 months after treatment. This study demonstrated that exposure-based Internet-CBT, tailored for adolescents with FAP or FD, is a feasible treatment that potentially improves pain intensity, gastrointestinal symptoms, and quality of life.     

Observers’ reactions to workplace incivility in the masculine domain: How does role congruency explain gender bias in future workers?

Based on Role Congruity Theory, we tested the hypothesis of gender bias by examining gender differences in observers’ evaluations of the awareness and acceptability of workplace incivility gender‐dyad interaction. Three hundred and ninety‐six Spanish high school students (55.3% female) read one scenario of overt incivility (publicly humiliates and openly doubts the employee's judgment) or covert (omits and pays little attention) from a leader (female vs. male) toward a subordinate (female vs. male) in engineering. Results indicated gender differences among observers. From the leader actor of incivility, males were more aware and accepted less the incivility when performed by a female leader in a male domain; whereas females were more aware and accepted less incivility than males in all cases. Regarding the subordinate target of incivility, only females were more aware and accepted less incivility, and both males and females were more aware and accepted less covert incivility. Our results reveal practical implications for interventions from a gender perspective.
