Commentary: What is the Meaning and Utility of the Psychopathy Concept?

The concept and measurement of psychopathy in young people is discussed with respect to five key issues: (1) the respective merits of self-reports and ratings by others; (2) whether callous/unemotional (CU) features may be more appropriately tapped by physiological measures; (3) the possible utility of genetic studies; (4) the distinctiveness of CU from other risk factors for antisocial behavior; and (5) the homogeneity of CU as a construct.     

Attention and the right-ear advantage: What is the connection?

Dichotic listening originally was a means of studying attention. Half a century ago Doreen Kimura parlayed the dichotic method into a noninvasive indicator of lateralized cerebral language representation. The ubiquitous right-ear advantage (REA) for verbal material was accepted as a concomitant of left-sided language lateralization and preferential conduction of right-ear messages to the left hemisphere. As evidence has accumulated over the past 50years showing the REA to be dynamic and modifiable, the concept of attention has become essential for interpreting the findings. Progress in understanding the role of attention has been manifested as a transition from efforts to document attention effects to efforts to characterize their mechanisms. We summarize the relevant evidence, trace the evolution of explanatory models, and outline contemporary accounts of the role of attention in dichotic listening.     

Hope and General Self-efficacy: Two Measures of the Same Construct?

The aim of this study was to test the extent to which hope measure is equivalent to general self-efficacy measure. Questionnaire data on these two constructs and other external variables were collected from 199 Chinese college students. The factor analytic results suggested that hope and self-efficacy items measured the same construct. The unidimensional model combining hope items and GSE items fit the data as well as the bidimensional model, indicating that their corresponding items measured the same underlying construct. Further analyses showed that hope and GSE did not correlate with external variables differently in a systematic manner. Most of these correlational differences were non-significant and negligible. These findings suggested that the literatures studying GSE and hope could be considered to be integrated and that researchers need to recognize and acknowledge the conceptual and operational similarities among these constructs in the literature.     

Socioeconomic Status and Health: What is the role of Reserve Capacity?

ABSTRACT— A robust, linear association between socioeconomic status (SES) and health has been identified across many populations and health outcomes. This relationship is typically monotonic, so that each step down the SES hierarchy brings increased vulnerability to disease and premature mortality. Despite growing attention to health disparities, scientists and policymakers have made little progress toward confronting their causes and implementing effective solutions. Using the reserve capacity model ( Gallo & Matthews, 2003 ) as an organizing framework, the current article examines the contribution of resilient psychosocial resources to socioeconomic disparities in physical health. Findings suggest that deficient psychosocial resources, such as low perceptions of control and social support, may be one of many factors that connect low SES with poor health. Additional research is needed to test these relationships and their underlying mechanisms, to consider interventions to enhance reserve capacity, and to evaluate the efficacy of such efforts in fostering resilience to socioeconomic hardship.     

What is the Problem of Non-Existence?

It is widely held that there is a problem of talking about or otherwise representing things that not exist. But what exactly is this problem? This paper presents a formulation of the problem in terms of the conflict between the fact that there are truths about non-existent things and the fact that truths must be answerable to reality, how things are. Given this, the problem of singular negative existential statements is no longer the central or most difficult aspect of the problem of non-existence, despite what some philosophers say.     

What is the Normativity of Meaning?

There has been much debate over whether to accept the claim that meaning is normative. One obstacle to making progress in that debate is that it is not always clear what the claim amounts to. In this paper, I try to resolve a dispute between those who advance the claim concerning how it should be understood. More specifically, I critically examine two competing conceptions of the normativity of meaning, rejecting one and defending the other. Though the paper aims to settle a dispute among proponents of the claim that meaning is normative, it should be of interest to those who challenge it. After all, before one takes aim, one’s target needs to be in clear view.

Rephrasing the madness and creativity debate: What is the nature of the creativity construct?

This paper aims to reframe the debates about the association between creativity and mental illness. For centuries the link between the two has been debated, yet research has largely ignored the underlying nature of creativity in this context. The full understanding of the creativity construct, however, is essential to completely grasp its relationship with psychopathology. Three possible models for the creativity construct are proposed: the existence of different kinds of creativity each associated with specific types of psychopathology, creativity operating as a continuum, and creativity as a single entity. Support for each model is examined among the current literature. It is concluded that all three models are viable possibilities for the conceptualization of the creativity construct, each offering ample predictions and hypotheses for future research.

What is the Philosophy of Information?

Computational and information-theoretic research in philosophy has become increasingly fertile and pervasive, giving rise to a wealth of interesting results. In consequence, a new and vitally important field has emerged, the philosophy of information (PI). This essay is the first attempt to analyse the nature of PI systematically. PI is defined as the philosophical field concerned with the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and the elaboration and application of information-theoretic and computational methodologies to philosophical problems. I argue that PI is a mature discipline for three reasons: it represents an autonomous field of research; it provides an innovative approach to both traditional and new philosophical topics; and it can stand beside other branches of philosophy, offering a systematic treatment of the conceptual foundations of the world of information and the information society.     

Underdetermination and Meaning Indeterminacy: What is the Difference?

The first part of this paper discusses Quine’s views on underdetermination of theory by evidence, and the indeterminacy of translation, or meaning, in relation to certain physical theories. The underdetermination thesis says different theories can be supported by the same evidence, and the indeterminacy thesis says the same component of a theory that is underdetermined by evidence is also meaning indeterminate. A few examples of underdetermination and meaning indeterminacy are given in the text. In the second part of the paper, Quine’s scientific realism is discussed briefly, along with some of the difficulties encountered when considering the ‘truth’ of different empirically equivalent theories. It is concluded that the difference between underdetermination and indeterminacy, while significant, is not as great as Quine claims. It just means that after we have chosen a framework theory, from a number of empirically equivalent ones, we still have further choices along two different dimensions.     

Creativity of university students: What is the impact of field and year of study?

There is a long‐lasting dispute about development of students' creativity in the course of their university education. Both the duration and major field of study may represent the educational effects. To address the issue, the present study collected data (N = 859) from a series of surveys of students in Hong Kong to clarify educational effects by controlling a number of background characteristics and prior scores on creativity. Apart from measuring self‐reported creative traits and creative products, it measured divergent thinking with five tasks to elicit students' creative ideas, which led to scores of fluency, flexibility, novelty, innovativeness, and originality. Results indicate the trend of monotonic decline in creativity with years of study at university and the general superiority of verbal creativity among students of humanities and social sciences, whereas business students had the highest scores on self‐assessed creative traits and products.

What is the link between regret and weakness of will?

This paper argues (a) that most contemporary accounts of weakness of will either implicitly or explicitly assume that regret is a typical or even necessary element of standard cases of weakness of will and (b) that this assumption is mistaken. I draw on empirical and philosophical work on self-assessment to show that regret need not accompany typical weak-willed behavior, and that we should therefore revise the dominant account of the difference between weakness of will and (mere) changes of mind.     

On the measurement of priming: What is the correct baseline?

Abstract

We argue, contrary to Ostergaard (this issue), that the baseline for measuring priming effects in “recognition/identification” experiments is correctly estimated by the subjects’ performance with non-primed items. There is no reason to assume, as Ostergaard (this issue) does, that priming that occurs in a single presentation of the target item is qualitatively different from priming that occurs, in the same experimental situation, in two or more presentations, or that empirical findings, such as stochastic independence between recognition and primed identification, are affected by the number of presentations of the target items at study.     

Psychosocial Stress and Cardiovascular Risk: What is the Role of Daily Experience?

We describe an ecological momentary assessment (EMA) protocol designed to measure daily life experiences along several psychosocial dimensions (Social Conflict, Task Demand, Decisional Control, Negative Affect, and Arousal) hypothesized to be relevant for cardiovascular disease risk. In a large community sample, these assessments have been administered in conjunction with ambulatory blood pressure (ABP) monitoring and measures of subclinical cardiovascular disease. Several results have emerged that support the promise of this approach. First of all, each of these dimensions of experience appears to be a trigger for cardiovascular activation, with movement on each scale being associated with significant within-person changes in heart rate and blood pressure in the natural environment. Second, there appear to be individual differences in physiological responsiveness to these dimensions of daily experience, with such differences being associated in some cases with laboratory-based assessments of cardiovascular reactivity, as might be expected. Third, EMA ratings are associated in several instances with (between-person) stable individual differences in ABP readings. And finally, we have found that some of the characteristics defined by our EMA ratings are related to measures of subclinical atherosclerosis. Such effects appear to be mediated, in part, by ABP. The advantages of using EMA measures for capturing the effects of psychosocial stressors are highlighted by comparing the predictive validity of these daily life assessments to traditional global self-reports. We conclude by describing future plans for use of this type of assessment protocol for helping us to characterize psychosocial characteristics relevant to cardiovascular disease risk. Personality and social processes during daily living may have an important impact not only on psychological functioning but also on physical health and disease. In this article we review our recent work involving the assessment of daily experience as a means of better understanding the role of psychosocial stress in cardiovascular disease risk. First, we outline the rationale for our interest in daily experience sampling for examining these processes, and we describe the methods we have adopted for this purpose. Next, we review findings from a recent study in which we have used these approaches to examine the role of psychosocial stress on ABP and atherosclerosis in a community-dwelling sample. We compare our approach to more traditional (global self-report and laboratory-observation) methods for examining these relationships in humans, and we discuss potential future directions for use of daily experience sampling in studies of health and behavior.     

What is the role of the cerebellum in motor learning and cognition?

The exact role of the cerebellum in motor learning and cognition is controversial. Nonetheless, recent ideas and facts have prompted an attempt at building and testing a more unified and coherent conceptualization. This article will suggest that the cerebellum might indeed participate in both motor control and cognition, and in motor adaptation, motor learning, and procedural learning. The proposed process would entail stimulus-response linkage through trial and error learning, and would consist of groupings of single-response elements-motor and cognitive-into large combinations. After practice, the occurrence of a sensory or experiential `context' would automatically trigger the combined response. The parallel fiber is the proposed agent of stimulus-response linkage and of combining the response elements. The attempt here is to focus on the role of the parallel fiber as a possible combiner of downstream motor and cognitive elements.
