Relationships Between Parental Negativity and Childhood Antisocial Behavior over Time: A Bidirectional Effects Model in a Longitudinal Genetically Informative Design

This study examined the direction and etiology underlying the relationships between parental negativity and early childhood antisocial behavior using a bidirectional effects model in a longitudinal genetically informative design. We analyzed parent reports of parental negativity and early childhood antisocial behavior in 6,230 pairs of twins at 4 and 7 years of age. Results from a cross-lagged twin model contribute to the understanding of the mechanisms underlying the bidirectional processes involved in parental negativity and childhood antisocial behavior. Specifically, the findings of this study suggest that the association between parenting and child antisocial behavior is best explained by both parent-driven and child-driven effects. We found support for the notion that parent's negative feelings towards their children environmentally mediate the risk for child antisocial behavior. We also found evidence of genetically mediated child effects; in which genetically influenced antisocial behavior evoke parental negativity towards the child.     

Perspective-dependence and Critical Thinking

Recent theories of critical thinking have stressed the importance of taking into consideration in critical enquiry the perspectives, or presuppositions, of both the speaker whose statements are under scrutiny and the critic himself. The purpose of the paper is to explore this idea from an epistemological (rather than a pedagogical or psychological) point of view. The problem is first placed within the general context of critical thinking theory. Three types of perspective-dependence are then described, and the consequences of each for the possibility of critical discussion discussed. It is concluded that although it is essential in critical discussion to take the other’s perspective into consideration, perspective-dependence does not exclude the possibility of criticism.     

Identifying and analyzing the construction and effectiveness of offensive plays in basketball by using systematic observation

In the field of sports research, there is a growing need for the rigorous collection of data that provide empirical evidence about the complex reality they refer to. Although sports psychology research has advanced considerably in recent years, in both extent and quality, one area of research that remains relatively unexplored is the dynamics of the sports group and the influence of the group on its members (George & Feltz, 1995; Widmeyer, Brawley, & Carron, 1992). Key aspects in this regard include the presence of regularities that are not detectable through visual inference or traditional methods of data analysis, the lack of standard observation instruments, and, assuming priority, the need to develop powerful, computerized coding systems, all of which must form part of an approach that is suitable for natural and habitual contexts. The present study is part of a broader research project concerning ACB teams (first Spanish basketball division) and considers the interaction context before teams try to score (where this is understood as how teams create scoring opportunities) as the core aspect that links team play. This investigation proposes a new model of analysis for studying the effectiveness and construction of offensive basketball plays in order to identify their outcomes, thus providing coaches with an important device for improving or consolidating them.     

Spinal and locus coeruleus noradrenergic lesions abolish the analgesic effects of 5-methoxy-N,N-dimethyltryptamine

Two experiments were performed on Sprague-Dawley rats to study the effects of noradrenaline and 5-hydroxytryptamine depletion upon the antinociceptive effects of acute 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) administration. 6-Hydroxydopamine-induced lesions following microinjections to either the locus coeruleus or the spinal cord (lumbar) abolished completely 5-MeODMT-induced analgesia in the tail-flick, hot-plate, and shock titration tests whereas 5,7-dihydroxytryptamine-induced lesions of the nucleus raphe magnus and the lumbar spinal cord attenuated 5-MeODMT analgesia in the tail-flick and shock titration tests. Thus, the experiments serve to demonstrate an important interaction between descending noradrenergic and serotonergic pathways, possibly at a spinal locus.     

EFFECTS OF LYSERGIC ACID DIETHYLAMIDE (LSD-25) ON NORMAL SUBJECTS IN A SCHIZOPHRENIA-DISCRIMINATING TEST BATTERY

Psychological tests with differing sensitivity to schizophrenic reactions were administered to eight normal subjects after oral intake of 75–100 μ g LSD-25. Control data were obtained from placebo trials. Six of the tests were chosen as sensitive to schizophrenic reactions, two tests as so-called 'hold' tests, and another test as a measure of attention, which is supposed to be reduced by LSD. Significantly lower results were obtained on four of the six sensitive tests after LSD, on one of the 'hold' tests, and on the attention test.     

STUDIES IN THE PSYCHOLOGICAL EFFECTS OF A NEW DRUG (DIETHYLPROPION)

In a 'triple blind' study on 30 subjects, 50 mg diethylpropion was compared with 10 mg dexamphetamine, 50 mg phenmetrazine, 250 mg caffeine, and placebo. The effects were measured in 5 subjective variables at 40 minutes intervals up to 4 hours. Clear trends were obtained in 'happiness', 'alertness' and 'pleasantness'. Peak effects were seen at about two hours, but in pleasantness the effects of phenmetrazine were increased even after that time. The demonstrated effects were discussed in relation to data on abuse of diethylpropion and phenmetrazine.     

BEHAVIOUR OF RATS UNDER THE INFLUENCE OF ETHYL ALCOHOL IN AN OPEN-FIELD SITUATION

In a standardized open-field test, ambulation, defecation, time of non-locomotor activity, time spent motionless, preening, and rearing were recorded. Inter-observer differences were small. Test repetition caused significant behavioural changes. Different rats were used for each of five doses of alcohol (0.5–2 mg/g). The lowest dose (0.75 mg/g) affecting behaviour significantly increased time motionless, decreased non-locomotor activity, and depressed preening. Ambulation was the last sensitive measure of behaviour. The results suggest that arousal mechanisms are particularly sensitive to alcohol. The procedure seems useful for studies of effects of small doses of alcohol.     

Science as a Vocation in the Era of Big Data: the Philosophy of Science behind Big Data and humanity’s Continued Part in Science

We now live in the era of big data, and according to its proponents, big data is poised to change science as we know it. Claims of having no theory and no ideology are made, and there is an assumption that the results of big data are trustworthy because it is considered free from human judgement, which is often considered inextricably linked with human error. These two claims lead to the idea that big data is the source of better scientific knowledge, through more objectivity, more data, and better analysis. In this paper I analyse the philosophy of science behind big data and make the claim that the death of many traditional sciences, and the human scientist, is much exaggerated. The philosophy of science of big data means that there are certain things big data does very well, and some things that it cannot do. I argue that humans will still be needed for mediating and creating theory, and for providing the legitimacy and values science needs as a normative social enterprise.     

Multiple layers of information processing in deductive reasoning: combining dual strategy and dual-source approaches to reasoning

The idea that inferential performance cannot be analyzed within a single model has been suggested within two theoretical contexts. The dual strategy model suggests that people reason using different approaches to processing statistical information. The dual-source model suggests that people reason probabilistically using both statistical information and some intuition about logical form. Each model suggests that people have different approaches to processing information while making inferences. The following studies examined whether these different forms of information processing were equally present during reasoning. Participants were given a series of problems designed to distinguish counterexample from statistical reasoners. They were then given a series of MP or AC inferences for which identical statistical information was provided. Results show that MP inferences were considered to be deductively valid more often than equivalent AC inferences. The effect of logical form was independent of reasoning strategy, and of relatively equivalent size for both counterexample and statistical reasoners. The second study examined explicitly probabilistic inferences, and showed smaller effects of logical form and of reasoning strategy, although with a complex set of interactions. These results show that understanding the way that people use information when making inferences requires a multidimensional approach.
