Epistemicism and the Combined Spectrum

Derek Parfit's combined‐spectrum argument seems to conflict with epistemicism, a viable theory of vagueness. While Parfit argues for the indeterminacy of personhood, epistemicism denies indeterminacy. But, we argue, the linguistically based determinacy that epistemicism supports lacks the sort of normative or ontological significance that concerns Parfit. Thus, we reformulate his argument to make it consistent with epistemicism. We also dispute Roy Sorensen's suggestion that Parfit's argument relies on an assumption that fuels resistance to epistemicism, namely, that ‘the magnitude of a modification must be proportional to its effect.’     

Abortion outcome as a function of sex-role identification

The present study investigated the relationship between sex-role identification and abortion outcome in 120 women receiving first trimester abortions. The sex-role concept dimension was measured both by self-attributions of sex-role traits (as measured by the Bern Sex-Role Inventory) and by life-style (career vs. homemaker) trait attributions. Psychological and physiological aspects of abortion outcome were included; slightly more than 7% of scores were in the symptomatic range, similar to percentages found in previous studies. Both Androgyny (r = -.42, p <.001) and Masculinity (r = -.23, p <.05) were found to be related to positive abortion outcome. Androgyny was more strongly related, which suggests that a balance of masculine and feminine traits, at least for women in the post-abortion situation, is preferable to high Masculinity scores alone. Congruence between one's self-image and one's image of a career woman was also found to be related to abortion outcome (r =.31, p <.01). In attempting to differentiate between the upper and lower 10% of the distribution of abortion outcome, only two variables, Androgyny and self-career congruence, survived parameter criterion, and accounted for 32% of the variance.     

Rural Embedded Assistants for Community Health (REACH) Network: First-Person Accounts in a Community–University Partnership

Community research and action projects undertaken by community–university partnerships can lead to contextually appropriate and sustainable community improvements in rural and urban localities. However, effective implementation is challenging and prone to failure when poorly executed. The current paper seeks to inform rural community–university partnership practice through consideration of first-person accounts from five stakeholders in the Rural Embedded Assistants for Community Health (REACH) Network. The REACH Network is a unique community–university partnership aimed at improving rural health services by identifying, implementing, and evaluating innovative health interventions delivered by local caregivers. The first-person accounts provide an insider’s perspective on the nature of collaboration. The unique perspectives identify three critical challenges facing the REACH Network: trust, coordination, and sustainability. Through consideration of the challenges, we identified several strategies for success. We hope readers can learn their own lessons when considering the details of our partnership’s efforts to improve the delivery infrastructure for rural healthcare.     

Rising to the threat: Reducing stereotype threat by reframing the threat as a challenge

In two experiments, we found that the performance-inhibiting consequences of stereotype threat were eliminated when the threat was subtly reframed as a challenge. In Experiment 1, Black school children in North Carolina completed a 10-item mathematics test. Participants who reported their race before taking the test performed more poorly than participants who reported their race after completing the test, unless the test was framed as a challenge. Experiment 2 replicated this effect with undergraduates at a prestigious university. When reminded that they graduated from high schools that were poorly represented at the university, they performed more poorly than their peers on a math test. However, when the test was reframed as a challenge, this threat had no effect on their performance. These findings are discussed in terms of their theoretical and practical applications for both educational and athletic training.     

Lateralization of auditory language functions: a dynamic dual pathway model

Spoken language comprehension requires the coordination of different subprocesses in time. After the initial acoustic analysis the system has to extract segmental information such as phonemes, syntactic elements and lexical-semantic elements as well as suprasegmental information such as accentuation and intonational phrases, i.e., prosody. According to the dynamic dual pathway model of auditory language comprehension syntactic and semantic information are primarily processed in a left hemispheric temporo-frontal pathway including separate circuits for syntactic and semantic information whereas sentence level prosody is processed in a right hemispheric temporo-frontal pathway. The relative lateralization of these functions occurs as a result of stimulus properties and processing demands. The observed interaction between syntactic and prosodic information during auditory sentence comprehension is attributed to dynamic interactions between the two hemispheres.     

The brain generates its own sentence melody: a Gestalt phenomenon in speech perception

Brain processes underlying spoken language comprehension comprise auditory encoding, prosodic analysis and linguistic evaluation. Auditory encoding usually activates both hemispheres while language-specific stages are lateralized: analysis of prosodic cues are right-lateralized while linguistic evaluation is left-lateralized. Here, we investigated to what extent the absence of prosodic information influences lateralization. MEG brain-responses indicated that syntactic violations lead to early bi-lateral brain responses for syntax violations. When the pitch of sentences was flattened to diminish prosodic cues, the brain's syntax response was lateralized to the right hemisphere, indicating that the missing pitch was generated automatically by the brain when it was absent. This represents a Gestalt phenomenon, since we perceive more than is actually presented.     

Overcoming intuition: metacognitive difficulty activates analytic reasoning

Humans appear to reason using two processing styles: System 1 processes that are quick, intuitive, and effortless and System 2 processes that are slow, analytical, and deliberate that occasionally correct the output of System 1. Four experiments suggest that System 2 processes are activated by metacognitive experiences of difficulty or disfluency during the process of reasoning. Incidental experiences of difficulty or disfluency--receiving information in a degraded font (Experiments 1 and 4), in difficult-to-read lettering (Experiment 2), or while furrowing one's brow (Experiment 3)--reduced the impact of heuristics and defaults in judgment (Experiments 1 and 3), reduced reliance on peripheral cues in persuasion (Experiment 2), and improved syllogistic reasoning (Experiment 4). Metacognitive experiences of difficulty or disfluency appear to serve as an alarm that activates analytic forms of reasoning that assess and sometimes correct the output of more intuitive forms of reasoning.     

On being happy but fearing failure: The effects of mood on self-handicapping strategies

Does temporary mood influence people’s tendency to engage in self-handicapping behaviors? Based on past research on self-handicapping and recent work on affect and social behaviors, this experiment predicted and found that positive mood significantly increased the tendency to engage in two kinds of self-handicapping strategies. Participants (N = 94) first received contingent or non-contingent positive feedback about performance on a task of ‘cognitive abilities’, and then underwent a positive, neutral, or negative mood induction using video films. Self-handicapping was assessed in terms of their subsequent preference for (a) drinking a performance-enhancing, or performance-inhibiting herbal tea, and (b) engaging or not engaging in performance-enhancing cognitive practice. As predicted, happy mood and non-contingent feedback significantly increased self-handicapping on both measures. The implications of these results for everyday performance tasks, and for recent affect-cognition theories, are discussed.     

Suppressing Secrecy Through Metacognitive Ease: Cognitive Fluency Encourages Self-Disclosure

ABSTRACT— Understanding when people reveal unfavorable information about themselves is both practically and theoretically important. Existing research suggests that people tend not to adopt stable disclosure strategies, and consequently disclose too much information in some situations (e.g., embarrassing personal information on Facebook) and too little in other situations (e.g., risky sexual behavior to a physician during diagnosis of a possible sexually transmitted disease). We sought to identify a domain-general cue that predicts self-disclosure patterns. We found that metacognitive ease, or fluency, promoted greater disclosure, both in tightly controlled lab studies (Studies 1a, 1b, and 3) and in an ecologically valid on-line field study (Study 4). Disfluency tended to prime thoughts and emotions associated with risk, which might be one reason why people who experience disfluency are less comfortable with self-disclosure (Studies 2 and 3). We conclude by discussing the implications of these results for theory and clinical practice.
