Can Parts of Space Move? On Paragraph Six of Newton’s Scholium

Paragraph 6 of Newtons Scholium argues that the parts of space cannot move. A premise of the argument – that parts have individuality only through an order of position – has drawn distinguished modern support yet little agreement among interpretations of the paragraph. I argue that the paragraph offers an a priori, metaphysical argument for absolute motion, an argument which is invalid. That order of position is powerless to distinguish one part of Euclidean space from any other has gone virtually unremarked. It remains uncertain what the import of the paragraph is but it is not close to apparently similar arguments of Leibniz.     

Problems With the Argument From Fine Tuning

The argument from fine tuning is supposed to establish the existence of God from the fact that the evolution of carbon-based life requires the laws of physics and the boundary conditions of the universe to be more or less as they are. We demonstrate that this argument fails. In particular, we focus on problems associated with the role probabilities play in the argument. We show that, even granting the fine tuning of the universe, it does not follow that the universe is improbable, thus no explanation of the fine tuning, theistic or otherwise, is required.     

Susceptibility of the MMPI-2 clinical, restructured clinical (RC), and content scales to overreporting and underreporting

The authors examined and compared the susceptibility of three Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scale sets (Clinical, Restructured Clinical [RC], and Content) to over- and underreporting using five analog samples. Two samples of 85 and 191 undergraduate students, respectively, took the MMPI-2 under underreporting versus standard instructions. Three samples consisting of 42 undergraduates, 73 psychiatric inpatients, and 84 medical patients took the MMPI-2 under overreporting versus standard instructions. A comparison of the effect sizes across the three sets of scales indicated that Clinical Scale scores are not less susceptible to distortion than the Content or RC Scales. An apparent lesser susceptibility to underreporting for the Clinical Scales was an artifact of the subtle items' effect on these scales.     

Using overt rehearsals to explain word frequency effects in free recall

Three experiments examined the word frequency effect in free recall using the overt rehearsal methodology. Experiment 1 showed that lists of exclusively high-frequency (HF) words were better recalled, were rehearsed more, and were rehearsed to more recent serial positions than low-frequency (LF) words. A small HF advantage remained even when these 2 variables were equated. Experiment 2 showed that all these effects were much reduced with mixed lists containing both HF and LF words. Experiment 3 compared pure and mixed lists in a within-subject design and confirmed the findings of Experiments 1 and 2. It is argued that number of rehearsals, recency of rehearsals, and strength of interitem associations cause the word frequency effect in free recall.     

MMPI-2 validity scale characteristics in a correctional sample

The current study investigated the proportion of content-nonresponsive and content-responsive faking Minnesota Multiphasic Personality Inventory-2 (MMPI-2) protocols in a state corrections sample. Participants were 51,486 inmates who completed the MMPI-2 at the time they entered the Ohio Department of Rehabilitation and Correction system. Overall, approximately 79% of the study participants produced valid profiles. Of the entire study sample, 11.3% produced content-nonresponsive profiles, and 9.4% produced content-responsive faking profiles. African Americans produced a higher proportion of content-nonresponsive profiles than Caucasians, and women were slightly more likely than men to produce content-responsive faking profiles. Differences in level of education between African Americans and Caucasians did not account for the disparity in content-nonresponsive profiles. Implications for current practice and future research are discussed.     

Acquired equivalence and distinctiveness in human discrimination learning: evidence for associative mediation

In the first stage of Experiments 1-3, subjects learned to associate different geometrical figures with colors or with verbal labels. Performance in Stage 2, in which the figures signaled which of 2 motor responses should be performed, was superior in subjects required to make the same response to figures that had shared the same Stage 1 associate. A third stage of testing showed that the events used as associates in Stage 1 were capable of evoking the motor response trained in Stage 2, an outcome predicted by an associative interpretation of such transfer effects. Experiment 4 provided evidence that the relevant associations can be effective in controlling motor responding even when subjects report an antagonistic relationship between events.     

Emotional effect of physical aggression among adults in the general population in a Canadian province

The emotional effect of personal involvement in physical aggression was examined in a random sample of 1,753 adults from Ontario, Canada, using Computer Assisted Telephone Interviewing (response rate of 67%). Respondents reported a range of emotional responses from feeling good or justified to feeling angry, upset, terrified, disgusted, hurt, and embarrassed. Open-ended responses regarding emotional response were rated by the authors for 149 incidents of aggression, which yielded five categories: (1) positive impact 4%, (2) no feeling or no effect 31%, (3) mildly negative 20%, (4) moderately negative 28%, and (5) severely negative 17% (Kappa statistic of interrater agreement=.77). The substantial proportion of incidents involving positive or no emotional response suggests that a greater understanding of aggression among individuals can be gained by the development and application of a quantitative measure of emotional response that reflects the full range of emotions (positive and negative), using dimensions identified in this study such as feeling upset, fear, and anger.     

Chunking versus foraging search patterns by rats in the hierarchically baited radial maze

Rats were exposed to a radial maze containing six black smooth arms and six wire-grid-covered arms and a striped 'exit arm' in experiment 1. The probability of a black or grid arm being baited (5/6 vs 1/6) with sunflower seeds was associated with its proximal cue for some rats (the Relevant Arm Cue group) but not for others (the Irrelevant Arm Cue group). All rats could terminate a trial and receive a highly preferred morsel of apple by entering the exit arm only after having sampled all six seed-baited arms. Relevant Arm Cue rats usually chose some arms from the more densely baited set before choosing an arm from the less densely baited set and made fewer reentries than Irrelevant Arm Cue rats. Although such clustered, higher choice accuracy in the Relevant Arm Cue group corresponds to human clustered, better recall of verbal items from lists hierarchically organized by categories, these rats did not similarly exhaustively retrieve items (arm locations). That is, when required to terminate a trial by entering the 'exit' arm for an apple morsel after having sampled all seed-baited arms, both groups were equally unable to withhold making nonrewarded premature exits. This nonexhaustive foraging search pattern was maintained in the next two experiments in which the radial maze was reduced to three black and three grid arms along with the striped 'exit' arm and in which black and grid arm cues were paired with number of seeds (eight or one) in an arm for Relevant Arm Cue rats. Although Relevant Arm Cue rats displayed perfect clustering by entering all eight-seeded arms before a one-seeded arm, they made more premature exits and reentries into eight-seeded arms in experiment 2 or when forced to enter all eight-seeded arms in experiment 3 than did Irrelevant Arm Cue rats. These foraging tendencies prevent accurate estimations of the amount of information (i.e., arm locations) rats can 'chunk'. Electronic Publication     

Do the right thing! Rule finitism, rule scepticism and rule following

Rule following is often made an unnecessary mystery in the philosophy of social science. One form of mystification is the issue of 'rule finitism', which raises the puzzle as to how a learner can possibly extend the rule to applications beyond those examples which have been given as instruction in the rule. Despite the claim that this problem originated in the work of Wittgenstein, it is clear that his philosophical method is designed to evaporate, not perpetuate, such problems. The supposed problem of rule finitism is malformed, deriving from misconceptions about the relation between understanding a rule and making an application of it.
