Partition epistemology and arguments from analogy

Nineteenth and twentieth century philosophies of science have consistently failed to identify any rational basis for the compelling character of scientific analogies. This failure is particularly worrisome in light of the fact that the development and diffusion of certain scientific analogies, e.g. Darwin’s analogy between domestic breeds and naturally occurring species, constitute paradigm cases of good science. It is argued that the interactivist model, through the notion of a partition epistemology, provides a way to understand the persuasive character of compelling scientific analogies without consigning them to an irrational or arational context of discovery.     

Selective attention and avoidance on a pictorial cueing task during stress in clinically anxious and depressed participants

Although it is well established that attentional biases exist in anxious populations, the specific components of visual orienting towards and away from emotional stimuli are not well delineated. The present study was designed to examine these processes. We used a modified spatial cueing task to assess the speed of engagement and disengagement from supraliminal and masked pictorial cues depicting threat, dysphoria, or neutral content in 36 clinically anxious, 41 depressed and 41 control participants. Participants were randomly assigned to a stress or neutral condition. During stress, anxious participants were slow to disengage from masked left hemifield pictures depicting threat or dysphoria, but were quick to disengage from supraliminal threat pictures. Information processing in anxious participants during stress was characterized by early selective attention of emotional stimuli, occurring prior to full conscious awareness, followed by effortful avoidance of threat. Depressed participants were distinct from the anxious group, displaying selective attention for stimuli depicting dysphoria, but not threat, during the neutral condition. In sum, attentional biases in clinical populations are associated with difficulties in the disengagement component of visual orienting. Further, a vigilant-avoidant pattern of attentional bias may represent a strategic attempt to compensate for the early activation of a fear response.     

Videogame Addiction and its Treatment

For many, the concept of videogame addiction seems far-fetched, particularly if their concepts and definitions of addiction involve the taking of drugs. This paper overviews the small, but growing area of videogame addiction and then examines the treatment options available for those affected by excessive videogame playing. An overview of the available empirical literature appears to indicate that adverse effects are likely to affect only a relatively small subgroup of players and that frequent players are the most at-risk for developing problems. Worldwide, there are relatively few practitioners that specialise in the treatment of videogame addiction and this may be because there are so few players who are genuinely addicted to playing videogames. However, the Internet may be facilitating excessive online game playing as evidenced by the increasing number of specialist addiction treatment clinics for online videogame addiction. This paper overviews the various approaches that have been used as an intervention in treating videogame addicts, including online support groups, 12-step programmes, behavioural and cognitive-behavioural therapies, and motivational interviewing.     

EXPERIENCE AND CONTENT

The 'content view', in slogan form, is 'Perceptual experiences have representational content'. I explain why the content view should be reformulated to remove any reference to 'experiences'. I then argue, against Bill Brewer, Charles Travis and others, that the content view is true. One corollary of the discussion is that the content of perception is relatively thin (confined, in the visual case, to roughly the output of 'mid-level' vision). Finally, I argue (briefly) that the opponents of the content view are partially vindicated, because perceptual error is due to false belief.     

Measuring happiness: The higher order factor structure of subjective and psychological well-being measures

The nature and structure of well-being is a topic that has garnered increasing interest with the emergence of positive psychology. Limited research to date suggests two separate but related factors of subjective well-being and psychological well-being. Subjective well-being comprises an affective component of the balance between positive and negative affect, together with a cognitive component of judgments about one’s life satisfaction. Psychological well-being is conceptualised as having six components, including positive relations with others, autonomy, environmental mastery, self-acceptance, purpose in life and personal growth. In the current study, we used exploratory factor analysis and confirmatory factor analysis to examine the higher order factor structure of subjective and psychological well-being in a series of large UK samples. Analyses showed that subjective well-being and psychological well-being loaded separately onto two independent but related factors, consistent with previous research. Further, we demonstrated that these loadings did not vary according to gender, age or ethnicity, providing further support for the robustness of this higher order factor structure. The discussion locates these findings in context and explores future research directions on the associations between subjective and psychological well-being over time.     

When Can One Requirement Override Another?

I argue that any theory of moral obligation must be able toexplain two things: why we cannot be thrust into a moraldilemma through no fault of our own, and why we can get intoa moral dilemma through our own negligence. The most intuitivetheory of moral obligation cannot do so. However, I offer atheory of moral obligation that satisfies both of these criteria,one that is founded on the principle that if you are required todo something, then you would be blameworthy for failing to do it.I conclude by relating these results to the current literatureon moral dilemmas.     

Leadership and Adolescent Girls: A Qualitative Study of Leadership Development

This research investigated youth leadership experiences of adolescent girls who participated in a comprehensive feminist-based leadership program. This qualitative study utilized a grounded theory approach to understand changes that occurred in 10 female adolescent participants. The words of the participants revealed that initially they viewed leadership in traditional terms and were hesitant to identify themselves as leaders or to see themselves included within their concepts of leadership. Following the program their view of leadership expanded and diversified in a manner that allowed for inclusion of themselves within it. They spoke with greater strength and confidence and felt better positioned and inspired to act as leaders. Participants identified having examples of women leaders, adopting multiple concepts of leadership, and participating in an environment of mutual respect and trust as factors that contributed to their expanded conceptualization.
