Genetic Testing Likelihood: The Impact of Abortion Views and Quality of Life Information on Women’s Decisions

Little is known about factors predicting the likelihood of choosing genetic testing in college aged women versus older women, including knowledge of quality of life (QOL) associated with a disorder. Using vignettes with female college students (Experiment 1: n = 257, mean age = 19.70 yrs) and female faculty/staff/alumni (Experiment 2: n _nulliparous = 83, mean age = 30.20 yrs; n _mothers = 53, mean age = 33.77 yrs), we examined the contribution of multiple factors to predicting genetic testing likelihood for cystic fibrosis. We investigated malleable situational factors (style of genetic risk presentation and providing QOL information including physical and social aspects) and stable dispositional factors (abortion views). Parity (i.e., prior births) was more influential in women’s genetic testing likelihood than was age. Greater acceptability of abortion for oneself and self-assessed knowledge following QOL information were predictors of higher testing likelihood for college students. Greater acceptability of abortion for another person was a predictor for nulliparous women. Abortion views moderated the effect of predictors for nulliparous women and mothers. Findings encourage genetic counselors to utilize QOL information to promote informed decision making through genetic testing.     

Health and turnover of working mothers after childbirth via the work-family interface: an analysis across time

This study examined organizational levers that impact work-family experiences, participant health, and subsequent turnover. Using a sample of 179 women returning to full-time work 4 months after childbirth, we examined the associations of 3 job resources (job security, skill discretion, and schedule control) with work-to-family enrichment and the associations of 2 job demands (psychological requirements and nonstandard work schedules) with work-to-family conflict. Further, we considered subsequent impact of work-to-family conflict and enrichment on women's health (physical and mental health) 8 months after women returned to work and the impact of health on voluntary turnover 12 months after women returned to work. Having a nonstandard work schedule was directly and positively related to conflict, whereas schedule control buffered the effect of psychological requirements on conflict. Skill discretion and job security, both job resources, directly and positively related to enrichment. Work-to-family conflict was negatively related to both physical and mental health, but work-to-family enrichment positively predicted only physical health. Physical health and mental health both negatively influenced turnover. We discuss implications and opportunities for future research.     

Group‐based evaluations for pupil‐on‐teacher violence: The impact of teacher intervention strategy

Although extreme violence to teachers is rare, the fact remains that in the UK, 29% of teachers report having been physically assaulted by a pupil (ATL, 2008a ). The ways in which responsibility for such assaults are attributed can have legal, educational and managerial implications. In the current study, teachers (N = 66), pupils (N = 68) and parents (N = 64) from a large secondary school in the UK read an incident report form outlining an incident depicting a pupil physically assaulting a teacher. The incident report was manipulated such that, prior to being assaulted, the teacher had either separated the assailant pupil from another pupil using a physical or non‐physical intervention. Results revealed that participating parents' and teachers' evaluations of the assailant's parents and the teacher differed from those of pupils in several ways. The results are discussed in terms of group‐based responsibility for deviant behaviour and implications for teacher behaviour in response to pupil on teacher violence.

Why we simulate negated information: a dynamic pragmatic account

A well-established finding in the simulation literature is that participants simulate the positive argument of negation soon after reading a negative sentence, prior to simulating a scene consistent with the negated sentence (Kaup, Ludtke, & Zwaan, 2006; Kaup, Yaxley, Madden, Zwaan, & Ludtke, 2007). One interpretation of this finding is that negation requires two steps to process: first represent what is being negated then "reject" that in favour of a representation of a negation-consistent state of affairs (Kaup et al., 2007). In this paper we argue that this finding with negative sentences could be a by-product of the dynamic way that language is interpreted relative to a common ground and not the way that negation is represented. We present a study based on Kaup et al. (2007) that tests the competing accounts. Our results suggest that some negative sentences are not processed in two steps, but provide support for the alternative, dynamic account.     

The sensitivity of a palm-based psychomotor vigilance task to severe sleep loss

In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-192 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of wakefulness. Overall, standardized response speed scores on the 5-min PDA-PVT closely tracked those of the PVT-192; however, the PDA-PVT was generally associated with more lapses/minute. Closer inspection of the data indicated that when the level of sleep loss and fatigue became more severe (i.e., Day 3), the 5-min PDA-PVT was not quite as sensitive as the 10-min PVT-192 when 2- to 10-sec foreperiods were used for both. It is likely, however, that the observed differences between the two devices was due to differences in task length. Thus, the findings provide further evidence of the validity of the 5-min PDA-PVT as a substitute for the 10-min PVT-192, particularly in circumstances in which a shorter test is required and/or the PVT-192 is not as practical.     

The Self-Organization of Explicit Attitudes

ABSTRACT— How do minds produce explicit attitudes over several hundred milliseconds? Speeded evaluative measures have revealed implicit biases beyond cognitive control and subjective awareness, yet mental processing may culminate in an explicit attitude that feels personally endorsed and corroborates voluntary intentions. We argue that self-reported explicit attitudes derive from a continuous, temporally dynamic process, whereby multiple simultaneously conflicting sources of information self-organize into a meaningful mental representation. While our participants reported their explicit (like vs. dislike) attitudes toward White versus Black people by moving a cursor to a "like" or "dislike" response box, we recorded streaming x - and y -coordinates from their hand-movement trajectories. We found that participants' hand-movement paths exhibited greater curvature toward the "dislike" response when they reported positive explicit attitudes toward Black people than when they reported positive explicit attitudes toward White people. Moreover, these trajectories were characterized by movement disorder and competitive velocity profiles that were predicted under the assumption that the deliberate attitudes emerged from continuous interactions between multiple simultaneously conflicting constraints.     

Meaning and the External World

Realism, defined as a justified belief in the existence of the external world, is jeopardized by ‘meaning rationalism,’ the classic theory of meaning that sees the extension of words as a function of the intensions of individual speakers, with no way to ensure that these intensions actually correspond to anything in the external world. To defend realism, Ruth Millikan (1984, 1989a, b, 1993, 2004, 2005) offers a biological theory of meaning called ‘teleosemantics’ in which words, without requiring any contribution from the speaker’s intensions, are supposedly matched directly with their extensions by external norms. But even if one granted as a theoretical possibility that word meaning might possibly be stabilized through an external process, nonetheless, realists who wish to appeal to teleosemantics for a semantic proof of the external world must be capable of identifying these external norms, something that Millikan describes as highly fallible. Furthermore, because they can be aware of these norms only as these are internally represented, it would also be necessary for realists to verify that these internal representations accurately reflect the norms as they occur in the external world. But given that this is virtually the same stumbling block to realism found in meaning rationalism, it is concluded that teleosemantics is not likely to restore faith in this worldview.

Natural born killers: The genetic origins of extreme violence

The current article examines the influence of genetics and evolution on acts of extreme and criminal violence among human primates. Moderate aggression can function to increase an organism's reproductive success; extreme violence can place the organism at unnecessary risk. Genetic polymorphisms that have been linked to extreme acts of violence are reviewed as is research elucidating how genetic risk and environmental stress may interact to increase risk of extreme violence. Extreme violence is viewed as high-end variance in an evolutionarily adaptive process in which the propensity for aggression and violent behavior, in moderate doses, has been adaptive for individual humans.
