The contributions of strategy use to working memory span: a comparison of strategy assessment methods

In two experiments, we tested whether individual differences in strategy production account for individual differences in performance on a working memory span task. We measured the strategies used during a standard experimenter-paced operation span (OSPAN) task by having participants make both set-by-set reports of strategy use for individual item sets and global reports of strategy use. In Experiment 1, although normatively effective strategies were self-reported on only a small proportion of OSPAN sets, individual differences in effective strategy use correlated with span performance. Experiment 2 replicated this outcome using a sample of 100 participants but, as important, it demonstrated that individual differences in effective strategy use did not mediate the relationship between OSPAN and measures of verbal ability. Discussion focuses on the interpretation of strategy-span relationships and the relative utility of general reports of strategy use versus the set-by-set reports introduced here for the OSPAN task.     

Free will,bound and unbound: reflections on Shaun Nichols’ <Emphasis Type="Italic">bound</Emphasis>

Nichols’ Bound presents interesting new angles on traditional debates about free will and moral responsibility, relating them to the latest empirical research in psychology, social sciences and experimental philosophy. In experimental philosophy, he cites numerous recent studies showing that there are strong incompatibilist strands in folk intuitions about free will and responsibility, taking issue with other recent studies claiming that folk intuitions are predominantly compatibilist. But he also argues that incompatibilist folk intuitions are based on faulty reasoning and cannot be realized. We are left with a choice between an eliminativism about free will and moral responsibility (free will skepticism) or revising ordinary beliefs and practices in a compatibilist direction. Though Nichols sees problems with both these positions, he ultimately opts for the latter. Despite agreeing with Nichols on many points, I argue in this paper that he takes the libertarian view of free will off the table too precipitously, leaving us with too narrow a choice of options. I argue that we can make sense of an incompatibilist view of free will and responsibility without reducing it to mere chance or mystery and that it remains an open scientific question whether we can have such a free will.     

Religious belief,age, and sexual orientation on attributions of younger and older gay and heterosexual men

Using 4 vignettes and 20 response items, this exploratory study investigated attributions about older or younger gay or heterosexual men with a history of multiple sex partners, substance abuse, and legal problems. The character is diagnosed with a terminal illness and two options for care: no treatment or an aggressive treatment protocol with a small chance of recovery. When controlling for respondents’ (N?=?324) religious identification, frequency of attendance at religious services, and ethno-cultural identification, a General Linear Model was significant (F?=?57.014, df?=?20, p?<?.001). Differences in the vignette responses centred on perceptions of quality of life, the character's lifestyle, and suicide.     

Examining Cognitive Functioning Following TASER Exposure: A Randomized Controlled Trial

Individuals who experience electrical injury suffer significant, sometimes long‐term deficits in neuropsychological functioning. The TASER, an electrical device used by thousands of police departments, generates a high‐voltage (up to 50 000 V), low‐amperage (2.1 mA) current of electricity that is designed to disable a resistive criminal suspect. Questions have emerged regarding the potential for TASER exposure to cause impairment in cognitive functioning. In the current study, healthy human volunteers were randomly assigned to four groups, two of which received a TASER exposure. Participants completed a battery of cognitive tests before and after receiving their assigned treatment. Participants who received a TASER exposure experienced statistically meaningful declines in measures of verbal learning and memory, although deficits lasted less than 1 hour. After TASER exposure, participants also self‐reported significant difficulties with concentration, anxiety, and feeling overwhelmed. Other dimensions of cognitive functioning were not affected. Our findings show that the effects of TASER exposure on brain functioning are not well understood. Copyright © 2015 John Wiley & Sons, Ltd.     

Moral Responsibility,Reactive Attitudes and Freedom of Will

In his influential paper, “Freedom and Resentment,” P. F. Strawson argued that our ordinary practices of holding persons morally responsible and related reactive attitudes (such as blame, resentment, indignation, and moral approval) were wholly “internal” to the practices themselves and could be insulated from traditional philosophical and metaphysical concerns, including concerns about free will and determinism. This “insulation thesis” is a controversial feature of Strawson’s influential paper; and it has had numerous critics. The first purpose of this paper is to explain my own reasons for thinking that our practices of holding responsible cannot be entirely insulated from incompatibilist concerns about freedom and determinism. The second purpose is to argue that these incompatibilist concerns are in fact legitimate concerns: There are sound reasons to believe that our ordinary practices of holding persons morally responsible do require at least sometimes in our lives that we must be capable of acting freely in a manner that is not determined. I defend this thesis by spelling out why I believe various compatibilist strategies attempting to show that moral responsibility is compatible with determinism fail to show this. In the course of this critique, a general theme will emerge: In order to do full justice to our ordinary practices of holding persons responsible and the freedoms thus involved, one must distinguish between different types of freedom, and in particular, between freedom of action and freedom of will.     

Biased interpretation in perfectionistic concerns: an experimental investigation

Background and objectives: Perfectionism is associated with the development and maintenance of several disorders. Given the importance of perfectionism understanding the biased information processes that underpin it is critical. The present study tested the hypothesis that heightened concern over mistakes subscale scores of the Frost Multidimensional Perfectionism Scale are characterized by a tendency to impose emotionally negative interpretations on perfectionism-relevant situations.

Method and design: Seventy-six non-clinical, general population participants’ were presented with interpretations of scenarios where a protagonist was described as achieving well above what was required, but fell short of their own high standard. Using a within-subjects, quasi-experimental design, we assessed interpretations of these scenarios by examining the degree to which participants rated test sentences as being likely implications of the original scenarios.

Results: A generalized linear mixed model revealed higher concern over mistakes scores were associated with an increased tendency to rate negative target test sentences as being similar to the original perfectionism-relevant scenarios, and a reduced tendency to rate positive target test sentences as being similar to these original scenarios.

Conclusions: The findings provide support for the cognitive–behavioral model of perfectionism. These findings support the inclusion of strategies in cognitive–behavioral treatment of perfectionism to reduce interpretation bias.     

Web-based strategies to disseminate a sun safety curriculum to public elementary schools and state-licensed child-care facilities.

The Sunny Days, Healthy Ways curriculum, which has been effective in previous trials, was disseminated to public elementary schools (n=2,030) and state-licensed child-care facilities (n=3,755) in 4 states. Two Web sites were created, varying in the amount and type of information. Mailings referred principals and directors to the sites. Overall 117 unique users made 172 visits to the sites. More repeat visits were made to the enhanced than to the basic site (p=.04). In a survey, 20.0% of principals and directors recalled receiving the mailings and 80.9% of these read them. Web-based strategies were weak, but the low response rate may be typical for such marketing. They will require supplementation by more personal approaches.
