Costs and benefits of strategy construction in a speeded discrimination task

The costs and benefits of constructing and utilizing a strategy for performing a speeded discrimination task were assessed in terms of time and mental resources. The strategy involved using information about the position a word occupied in order to respond to its identity more rapidly. The resources used to construct and utilize the strategy were assessed from responses to probes presented at various times during the task. In Experiment 1, the probe required a manual response, whereas in Experiment 2, the probe required a vocal response. Strategy construction interfered with the probe task in Experiment 1 but not in Experiment 2, suggesting that strategy construction required resources specific to the manual response system. There was also some evidence that strategy construction required general resources, but the evidence for specific resources was much stronger. The findings are consistent with our previous ideas about how the strategy is represented (Logan, 1980a; Logan & Zbrodoff, 1979). The different results with different responses to the probes point out important limitations on previous studies of probe interference and of cost-benefit analysis, which each focused on a single dimension of cost and benefit. The differences suggest that a multiple-resources approach to probe interference and cost-benefit analysis might be more appropriate.     

Perfectionism,Components of Stress Reactivity,and Depressive Symptoms

The current study examined the associations among dimensions of perfectionism, facets of stress reactivity, and self-reported depressive symptoms in 191 university students. Participants completed the Multidimensional Perfectionism Scale, the Perfectionism Cognitions Inventory, the Perceived Stress Reactivity Scale (PSRS), and a measure of depressive symptoms. The PSRS is a relatively new instrument that measures several distinguishable facets of stress reactivity including prolonged stress reactivity, reactivity to failure, and reactivity to social evaluation. Analyses confirmed that most of the perfectionism measures were associated with stress reactivity to failure experiences. Socially prescribed perfectionism and perfectionistic automatic thoughts were also associated with prolonged stress reactivity and reactivity to social evaluation. Moreover, all facets of stress reactivity were correlated with depressive symptoms. Finally, prolonged stress reactivity and reactivity to social evaluation mediated the links between perfectionism dimensions and depressive symptoms. The current findings provide general support for models of perfectionism and stress, and suggest that perfectionists have heightened sensitivities to stressors related to their self-definitions that are activated when threatening stressors involving these themes are experienced.     

Factors Affecting Reported Rates of Self-Injury*

ABSTRACT: The magnitude of variation in reported rates of self-injury suggests that factors other than actual incidence affect these rates. Factors that relate to the scope of the reporting network and to the intensity of contacts within this network are examined in detail to determine their effect on the reporting process. Differences in study design and reporting procedures are found to explain most of this variation and suggest the need for standardized techniques in studying the epidemiology of self-injury.     

Why Virginity Pledges Succeed or Fail: The Moderating Effect of Religious Commitment Versus Religious Participation

Over the past two decades, virginity pledges have proliferated in the US, despite mixed results regarding their effectiveness. Few studies have examined possible mechanisms that may shed light on why pledges work for some individuals but not others. Using a sample of emerging-adults aged 18–24 years old (n = 1,380), we examine the influence of religiosity on pledge signing and adherence, specifically whether the effectiveness of pledges is moderated by religiosity. Findings show that while religious participation is positively associated with signing a pledge, there is a moderating effect of religious commitment. That is, when religious commitment is high, adherence to the pledge is greater. However, for pledge signers with low religious commitment, there are unintended negative consequences with regard to increased participation in risky sexual behaviors, whether compared to other people who signed the pledge who are equally committed to their religion or to individuals who have never taken such a pledge. Implications for research and policy are discussed.     

A ‘Glaring Misunderstanding'? Schleiermacher,Barth and the Nature of Speculative Theology

Both Friedrich Schleiermacher and Karl Barth attempted to keep Christian dogmatic theology free from abstract philosophical speculation. However, Barth thinks that Schleiermacher is guilty of the very speculative theology to which Schleiermacher is so averse. This article will defend the claim that Barth misreads Schleiermacher's Glaubenslehre, such that Schleiermacher's theological method and formulations are just as anti‐speculative as Barth's. To defend this claim, this article examines what Barth considers to be speculative theology as well as his accusation that Schleiermacher is guilty of such speculative proposals. After considering Barth's challenges, this article defends Schleiermacher's methodology and theology as anti‐speculative. Finally, several additional accusations against Schleiermacher (those of Bruce McCormack and Thomas Curran) are overcome.     

What skilled typists don’t know about the QWERTY keyboard

We conducted four experiments to investigate skilled typists’ explicit knowledge of the locations of keys on the QWERTY keyboard, with three procedures: free recall (Exp.?1), cued recall (Exp.?2), and recognition (Exp.?3). We found that skilled typists’ explicit knowledge of key locations is incomplete and inaccurate. The findings are consistent with theories of skilled performance and automaticity that associate implicit knowledge with skilled performance and explicit knowledge with novice performance. In Experiment?4, we investigated whether novice typists acquire more complete explicit knowledge of key locations when learning to touch-type. We had skilled QWERTY typists complete a Dvorak touch-typing tutorial. We then tested their explicit knowledge of the Dvorak and QWERTY key locations with the free recall task. We found no difference in explicit knowledge of the two keyboards, suggesting that typists know little about key locations on the keyboard, whether they are exposed to the keyboard for 2 h or 12 years.     

Meditation Awareness Training (MAT) for Improved Psychological Well-being: A Qualitative Examination of Participant Experiences

Mindfulness-based interventions are reported as being efficacious treatments for a variety of psychological and somatic conditions. However, concerns have arisen relating to how mindfulness is operationalized in mindfulness-based interventions and whether its ‘spiritual essence’ and full potential treatment efficacy have remained intact. This qualitative study used interpretative phenomenological analysis to examine participant experiences regarding the acceptability and effectiveness of a newly designed secularized intervention called meditation awareness training (MAT) that follows a more traditional Buddhist approach to meditation. Participants (with issues of stress and low mood) reported experiencing improvements in psychological well-being due to receiving MAT. The wider implications are discussed.
