The Relation Between Self-Report Mindfulness and Performance on Tasks of Sustained Attention

Validation of self-report mindfulness measures has been promising, although comparisons with non-self-report instruments are lacking. Because past research suggests that mindfulness training is associated with improved attention, this study predicted that higher self-report mindfulness would be positively related to performance on tasks of sustained attention. Fifty undergraduates completed the Mindful Attention Awareness Scale (MAAS), the Kentucky Inventory of Mindfulness Skills (KIMS), the Cognitive and Affective Mindfulness Scale, Revised (CAMS-R), and performed the Continuous Performance Test II (CPT-II) and the Paced Auditory Serial Addition Test (PASAT). Mindfulness scores, as measured by the MAAS and CAMS-R, were negatively related to target omissions on the CPT-II (ps ≤ 0.001), but were not related to PASAT performance (ps ≥ 0.11). Scores on the KIMS were not related to the CPT-II or PASAT (ps ≥ 0.15). Results suggest that self-report mindfulness is related to exaggerated lapses of attention, as measured by the CPT-II.     

The Relation Between the Two Factors of Psychopathy and Intimate Partner Aggression

Psychopathy is a personality disorder that has emerged as a correlate of antisocial, impulsive, and violent behavior, including intimate partner violence (IPV). In the current study, we sought to explore the complex relationship between two factors of psychopathy and IPV perpetration. The Fearlessness-Dominance Factor I (PPI-I) assesses the affective-interpersonal traits of psychopathy, whereas the Impulsive-Antisociality Factor II (PPI-II) assesses the behavioral-lifestyle traits of psychopathy. Data from 114 couples was utilized in the current study. When using male self-report of IPV, all forms of violence were significantly correlated with PPI-I. No male self-report or female-report of any of the forms of violence were significantly correlated with PPI-II. Hierarchical regression was utilized to study the impact of psychopathy factors in predicting physical violence while controlling for demographic variables. In predicting women’s report of men’s violence, the addition of psychopathy factors to the model explained significantly more of the variance (F = 2.71; p < .05) above and beyond demographic variables. The addition of psychopathy factors to the model predicting men’s self-reported physical violence was also significant (F = 4.78, p < .001). These results suggest that individuals high in PPI-I may be at higher risk of IPV perpetration compared to those high in PPI-II.     

Choice Between Two Discrimination Tasks in Chimpanzees (Pan troglodytes)

The purpose of the present study was to investigate the effects of cognitive effort on a chimpanzee's choice between discrimination tasks. The tasks were of the matching-to-sample type. In Experiment 1, the chimpanzee was required to choose between a task providing a high reinforcement rate with high cognitive effort and a task providing a low reinforcement rate with low cognitive effort. Her choice depended on the reinforcement rate more than the cognitive effort. Experiments 2, 3, and 4 examined whether the kind of cognitive effort influenced the chimpanzee's choice. Experiment 2 manipulated the sample-choice relationship, so-called symmetry in the matching-to-sample tasks. Experiment 3 manipulated the number of comparison stimuli. Experiment 4 manipulated the delay interval between the sample and the comparison stimuli. In Experiments 2 and 3, the effects of the cognitive effort were confounded with those of the reinforcement rates. However, in one condition of Experiment 4, the chimpanzee preferred the simultaneous task to the delayed task, despite the lack of a significant difference in reinforcement rates between the two tasks. The present study demonstrated that the chimpanzee's choice of discrimination task depended on the cognitive effort involved, in addition to the reinforcement rate.

The Relationship Between a Mechanical Comprehension Test and Weapons-Training Tasks

The aim of the present study was to establish whether a relationship exists between recruit RT4 (mechanical comprehension) scores and a weapons-handling task from the Royal Marines (RM) recruit training course. This aim was achieved through the collection of subjective and objective performance data from RM recruits carrying out the tasks. Statistical analyses revealed that performance at weapons training was significantly related to RT4 score. On the basis of the findings, it was concluded that low mechanical comprehension scores appear to be related to difficulties with weapons-handling tasks. This is of interest given the known association between low mechanical comprehension scores and training wastage. It is recommended that the use of RT4 as a selection measure for RM training may reduce the number of recruits joining training who are at high risk of opting out at a later date.     

The Balance-Scale Dilemma: Either the Subject or the Experimenter Muddles Through

We examined two critiques of rule-assessment methodology: (a) the method does not take into consideration other rules that subjects use to solve problems, and (b) its multiple-choice format misrepresents subjects' cognitive level. In Study 1, high school students completed a paper-and-pencil, multiple-choice balance scale questionnaire. Their performance was assessed with Siegler's original rules and a revised set of rules that included an addition and a qualitative proportionality rule. Results showed that Siegler's Rule 3 was not homogeneous and that distinguishing specific patterns of answers among Rule 3 subjects increased the diagnostic value of the rule-assessment methodology. In Study 2, we compared rule-assessment methodology to the Piagetian clinical model. High school students solved balance-scale problems within each method. Results indicated an overall match between Piagetian levels and Siegler's rules, with the exception of Rule 3, suggesting again the pertinence of specifying alternative rules.     

经济增长、分配不平等与政治稳定的结构关系及其政策启示

经济增长与分配的不平等之间并不具有直接的互动关系,二者的关系不仅取决于特定的经济、政治和社会结构,而且取决于政府特定的公共政策。导致政府调整经济增长与收入分配关系政策的关键因素之一,是这二者关系对政治稳定的影响和威胁。因此,政策制定者应当将政治不稳定因素的聚集作为调整经济增长与收入分配关系的关键性信号。     

两种“内在价值”理论之争——重审摩尔对布伦塔诺的批评

在"是否承认内在价值"的问题上,摩尔属于布伦塔诺少有的同盟者,不过在一些重要方面摩尔却对后者提出了严厉批评:在"内在善好"概念上,摩尔批评布伦塔诺的说明方式没有清晰认识到"内在善好"仅仅取决于相关对象的内在本质而与情感无关;在偏爱原则上,摩尔批评布伦塔诺混淆了正当性的程度差异和正当的偏爱情感,而没有认识到前者才是决定价值排序的本质要素;在总量原则上,摩尔批评布伦塔诺没有恰当认识到在整体和部分的内在价值之间的复杂关系,甚至会导致恶劣的道德后果。通过重新审视上述批评可知,布伦塔诺不仅可以在很大程度上回应摩尔对其的批评,而且在"内在价值"理论上,他提供了一种与摩尔不同甚至更加精致的理论形态。重审及回应摩尔对布伦塔诺的批评也有助于弄清"内在价值"这种"实事"本身。     

Two Kinds of Time-Consciousness and Three Kinds of Content

This paper explores the distinction between perceiving an object as extended in time, and experiencing a sequence of perceptions. I argue that this distinction cannot be adequately described by any present theory of time-consciousness and that in order to solve the puzzle, we need to consider perceptual content as having three distinct constituents: Explicit content, which has a particular phenomenal character, modal content, or the kind of content that is contributed by the psychological mode, and implicit content, which lacks phenomenal character. These notions are then further clarified and related to each other.     

Inverted U-Shaped Function Between Flow and Cortisol Release During Chess Play

This study focused on the salivary cortisol level and its relation to the two components of flow (flow absorption and flow fluency) in tournament chess players exposed to one of the skill-demand-level manipulations (underload, fit, and overload). The aims of this study were to investigate how skill-demand-level manipulations affect cortisol release and how flow and cortisol release are related in the context of an engaging task. Specifically, the task involved fifty-seven tournament chess players playing chess against a software in one of the experimental groups. We assessed flow after chess playing for 25 min via questionnaire and collected saliva before chess playing (T1), right after chess playing (T2), and 10 min after T2 (T3). Our findings show that cortisol levels were affected by the skill-demand-level manipulations. At T3, participants in the overload group showed higher cortisol levels than participants in the fit and underload groups. There were no differences in cortisol release between the experimental groups at T2. In addition, we found the expected inverted U-shaped relation between cortisol release and flow absorption at T2. A moderate level of cortisol was associated with a higher level of flow absorption. In contrast, a higher level of cortisol was associated with a lower level of flow absorption. Against our expectations, flow fluency was not related to cortisol release. We discuss practical and theoretical implications of our results as well as potential for future research.     

The Relation Between Factual and Counterfactual Conditionals

What is the relation between factual conditionals: If A happened then B happened, and counterfactual conditionals: If A had happened then B would have happened? Some theorists propose quite different semantics for the two. In contrast, the theory of mental models and its computer implementation interrelates them. It postulates that both can have a priori truth values, and that the semantic bases of both are possibilities: states that are possible for factual conditionals, and that were once possible but that did not happen for counterfactual conditionals. Two experiments supported these relations. Experiment 1 showed that, like factual conditionals, certain counterfactuals are true a priori, and others are false a priori. Experiment 2 replicated this result and showed that participants selected appropriate paraphrases, referring, respectively, to real and to counterfactual possibilities, for the two sorts of conditional. These results are contrary to alternative accounts of conditionals.     

The Relation Between Self-Continuity and Measures of Identity

Conceptualizations of Erikson's (1968) fifth psychosocial stage, identity formation, have been criticized for failing to be inclusive of an individual's sense of self-continuity. However, recent research has shown that identity commitment is significantly correlated to measures of continuity. This study further examined the relation among measures of identity, including identity commitment and continuity. The results suggest that many of the current measures of identity do indeed share a significant amount of variance with continuity. The specific results concerning identity commitment and continuity add to the growing evidence that these constructs are reliably related.     

Two Kinds of Unknowing

Miranda Fricker claims that a “gap” in collective hermeneutical resources with respect to the social experiences of marginalized groups prevents members of those groups from understanding their own experiences (Fricker 2007). I argue that because Fricker misdescribes dominant hermeneutical resources as collective, she fails to locate the ethically bad epistemic practices that maintain gaps in dominant hermeneutical resources even while alternative interpretations are in fact offered by non‐dominant discourses. Fricker's analysis of hermeneutical injustice does not account for the possibility that marginalized groups can be silenced relative to dominant discourses without being prevented from understanding or expressing their own social experiences. I suggest that a gap in dominant hermeneutical resources is ambiguous between two kinds of unknowing: hermeneutical injustice suffered by members of marginalized groups, and epistemically and ethically blameworthy ignorance perpetrated by members of dominant groups.     

Two Kinds of Stakes

I distinguish two different kinds of practical stakes associated with propositions. The W‐stakes (world) track what is at stake with respect to whether the proposition is true or false. The A‐stakes (attitude) track what is at stake with respect to whether an agent believes (or relies on) the proposition. This poses a dilemma for those who claim that whether a proposition is known can depend on the stakes associated with it. Only the W‐stakes reading of this view preserves intuitions about knowledge‐attributions, but only the A‐stakes reading preserves the putative link between knowledge and practical reasoning that has motivated it.

Knowledge Representation: Two Kinds Of Emergence

Two different but closely related issues in current cognitive science will be considered in this essay. One is the controversial and extensively discussed question of how connectionist and symbolic representations of knowledge are related to each other. The other concerns the notion of connectionist learning and its relevance for the understanding of the distinction between propositional and nonpropositional knowledge. More specifically, I shall give an overview of a result in Rantala and Vadén (1994) establishing a limiting case correspondence between symbolic and connectionist representations and, on the other hand, study the problem, preliminarily investigated in Rantala (1998), of how propositional knowledge may arise from nonpropositional knowledge. I shall also try to point out that on some more or less plausible assumptions, often made by cognitive scientists, these results may have some significance when we try to comprehend the nature of human knowledge representation. Some of these assumptions are rather hypothethical and debatable for the time being and they will become justified in the future only if there will be more progress in the empirical and theoretical research on the brain and on artificial networks. The assumptions concern, besides some questions of the behavior of neural networks, such things as the relevance of pattern recognition for modelling human cognition, in particular, knowledge acquisition, and the relation between emergence and reduction.
