Walter Miles, Pop Warner, B. C. Graves, and the psychology of football

In 1926-1927, a graduate student, B. C. Graves, working with Stanford University psychologist Walter Miles and legendary football coach Pop Warner, conducted an investigation of variations in signal calling as they affected the charging times of football players. The study was one of two that involved Miles and the ingenious multiple chronograph that he had invented to time the reactions of seven players simultaneously. These studies represented a brief digression in the career of Miles, who certainly was no sport psychologist. They tell of an interesting collaboration between scientist and coaches that produced one of the richest studies in sport psychology in the first half of the twentieth century.     

Processing Speed Deficits in Attention Deficit/Hyperactivity Disorder and Reading Disability

The goal of the current study was to test whether deficits in processing speed (PS) may be a shared cognitive risk factor in reading disability (RD) and Attention Deficit/Hyperactivity Disorder (ADHD), which are known to be comorbid. Literature on ADHD and RD suggests that deficits on tasks with a speeded component are seen in both of these disorders individually. The current study examined a wide range of speeded tasks in RD, ADHD, comorbid RD+ADHD, and a control group to test whether RD and ADHD have similar profiles of PS deficits, and whether these deficits are shared by the two disorders. The results suggest that a general PS deficit exists in both clinical groups compared to controls, although children with RD demonstrate greater PS deficits than children with ADHD. Two tests (underadditivity and partial correlations) were conducted to test whether these PS deficits are shared. Since we found that PS deficits were underadditive in the comorbid group and that partialling PS reduced the correlation between RD and ADHD, it appears that PS is a shared cognitive risk factor that may help explain the comorbidity of these two disorders.     

The timing of brain events: reply to the "Special Section" in this journal of September 2004, edited by Susan Pockett

In this "Reply" paper, the arguments and experimental findings by Pockett, Pollen, and Haggard et al. are analyzed. It had been shown () that a 0.5s duration of repetitive activations of sensory cortex is required to produce a threshold of sensation. The view that this is due to a facilitatory buildup in excitatory state to finally elicit neuronal firing is shown to be incompatible with several lines of evidence. Objections to the phenomenon of subjective referral backwards in time (for the delayed sensation) are also untenable. report that a self-initiated act can, under hypnotic suggestion, appear to the subject to be "involuntary." The act under hypnosis is better viewed as one initiated unconsciously, not as an act of conscious will.     

Trade-offs and individual differences in evolved traits

Comments on Evolutionary psychology: Controversies, questions, prospects, and limitations (see record 2010-02208-001) by Confer et al. We applaud Confer et al.'s (February-March 2010) clarifications of the many misconceptions surrounding the use of evolutionary analyses in psychology. As they noted, such misunderstandings are common and result in a curious tendency of some of our colleagues to criticize evolutionary psychology without a firm understanding of evolution itself. Confer et al. also did an admirable job acknowledging current unresolved issues among evolutionary psychologists (e.g., the relative importance of group selection on humans). The above said, we disagree with their view that a current limitation of evolutionary psychology is its inability to explain phenomena "that appear to reduce an individual's reproductive success, and cannot be explained by mismatches with, or hijacking of, our psychological mechanisms by modern-day novel inputs" (Confer et al., 2010, p. 122). Mismatches between modern environments and environments of evolutionary adaptedness are only one set of explanations for seemingly maladaptive traits (Nesse, 2005). Another set involves evolutionary trade-offs.     

Personality Processes in Anger and Reactive Aggression: An Introduction

ABSTRACT The situational factors precipitating anger and reactive (i.e., emotional) aggression have been well documented in the social psychology literature. However, there are pronounced individual differences in reactivity to hostile cues that are equally important in understanding such outcomes. Indeed, in predicting tendencies toward anger and reactive aggression, it appears critical to simultaneously consider both individual difference and situational factors. This case is first made. Subsequently, the utility of this individual difference realm in understanding wider personality processes related to social cognition, reactivity, and self-regulation is highlighted. Individual difference frameworks of this type are scattered across multiple literatures. For this reason, the present special section of the Journal of Personality invited contributions from experts in developmental, social, cognitive, trait, and biological subdisciplines of psychology. The final section introduces the invited papers and makes a brief case for broader process-related conclusions that are generally apparent.     

Indeterminacy,Ultimacy, and the World: the Self-Creation of Religious Pluralism through Community and Creation

Common arguments for truth in religious pluralism absolutize an ultimate or lived component of religion, reducing a positive affirmation of plurality to deeper unity or exclusion. The arguments of John Hick, William Connolly, Nicholas Rescher, and S. Mark Heim fall into such a trap. By considering how an indeterminate concept of ultimacy, proposed by Robert C. Neville, fares against the problems their arguments raise, it will be shown that such a concept of ultimacy can both give rise to and grow out of communal experiences and the nature of the world. The indeterminate ultimate, communal experiences, and the world pluralize themselves once understood in mutual relation.     

On the Speed Sensitivity Parameter in the Lognormal Model for Response Times and Implications for High-Stakes Measurement Practice

In high-stakes testing, often multiple test forms are used and a common time limit is enforced. Test fairness requires that ability estimates must not depend on the administration of a specific test form. Such a requirement may be violated if speededness differs between test forms. The impact of not taking speed sensitivity into account on the comparability of test forms regarding speededness and ability estimation was investigated. The lognormal measurement model for response times by van der Linden was compared with its extension by Klein Entink, van der Linden, and Fox, which includes a speed sensitivity parameter. An empirical data example was used to show that the extended model can fit the data better than the model without speed sensitivity parameters. A simulation was conducted, which showed that test forms with different average speed sensitivity yielded substantial different ability estimates for slow test takers, especially for test takers with high ability. Therefore, the use of the extended lognormal model for response times is recommended for the calibration of item pools in high-stakes testing situations. Limitations to the proposed approach and further research questions are discussed.     

Effects of instruction on learners’ ability to generate an effective pathway in the method of loci

One of the most effective mnemonic techniques is the well-known method of loci. Learning and retention, especially of sequentially ordered information, is facilitated by this technique which involves mentally combining salient loci on a well-known path with the material to be learned. There are several variants of this technique that differ in the kind of path that is suggested to the user and it is implicitly assumed that these variants are comparable in effectiveness. The experiments reported in this study were designed to test this assumption. The data of two experiments show that participants who are instructed to generate and apply loci on a route to their work recall significantly more items in a memory test than participants who are instructed to generate and apply loci on a route in their house. These results have practical implications for the instruction and application of the method of loci.
