Specifying the self for cognitive neuroscience

Cognitive neuroscience investigations of self-experience have mainly focused on the mental attribution of features to the self (self-related processing). In this paper, we highlight another fundamental, yet neglected, aspect of self-experience, that of being an agent. We propose that this aspect of self-experience depends on self-specifying processes, ones that implicitly specify the self by implementing a functional self/non-self distinction in perception, action, cognition and emotion. We describe two paradigmatic cases - sensorimotor integration and homeostatic regulation - and use the principles from these cases to show how cognitive control, including emotion regulation, is also self-specifying. We argue that externally directed, attention-demanding tasks, rather than suppressing self-experience, give rise to the self-experience of being a cognitive-affective agent. We conclude with directions for experimental work based on our framework.     

Specifying levels of processing

This study examines the nature of stimulus processing under semantic and nonsemantic orienting instructions. Two experiments are reported in which subjects were presented with a series of trials each beginning with the presentation of a “decision word” about which they made either a semantic or non-semantic orienting decision. This decision was followed by a word in coloured ink whose colour subjects were required to name as quickly as possible. On half the trails the coloured word was the primary associate of the decision word whilst on the other half the two words were normatively unrelated. On completion of the experiments the subjects were given an unexpected free recall test. The semantic orienting condition led to longer colour naming latencies on associate trials whilst no such difference was found in the non-semantic condition. The semantic condition also produced higher levels of incidental recall although paradoxically an analysis of associative clustering in recall failed to show any difference between the two orienting conditions. The results are interpreted as support for the “Levels of Processing” approach to memory since they provide an index of processing depth which is independent of retention performance.     

Specifying the scope of 13-month-olds'' expectations for novel words

Recent research has documented that for infants as young as 12–13 months of age, novel words (both count nouns and adjectives) highlight commonalities among objects and, in this way, foster the formation of object categories. The current experiment was designed to capture more precisely the scope of this phenomenon. We asked whether novel words (count nouns; adjectives) are linked specifically to category-based commonalities from the start, or whether they also direct infants' attention to a wider range of commonalities, including property-based commonalities among objects (e.g. color, texture). The results indicate that by 12–13 months, (1) infants have begun to distinguish between novel words presented as count nouns versus. adjectives in fluent, infant-directed speech, and (2) infants expectations for novel words accord with this emerging sensitivity.     

Specifying factors in radiation risk perception

This is a study of risk perception and a test of a model of perceived risk. A scale measuring fear was factor analyzed and the resulting five fear factors were related to a large number of risk dimensions, both personal and general. Fear was only rather weakly related to perceived risk. Furthermore, perceived risk of two ionizing radiation hazards (nuclear power, X-rays) were investigated in more detail. These risk ratings were modelled on the basis of attitude, risk sensitivity, specific perceived risk of radiation, trust and an extended version of the traditional Psychometric Model, enhanced by the introduction of a factor of Tampering with Nature. It was found that risk perception could be well explained with this approach and the importance of Tampering with Nature, as well as specific perceived risk, were stressed.     

Specifying optimum examinees for item parameter estimation in item response theory

Information functions are used to find the optimum ability levels and maximum contributions to information for estimating item parameters in three commonly used logistic item response models. For the three and two parameter logistic models, examinees who contribute maximally to the estimation of item difficulty contribute little to the estimation of item discrimination. This suggests that in applications that depend heavily upon the veracity of individual item parameter estimates (e.g. adaptive testing or text construction), better item calibration results may be obtained (for fixed sample sizes) from examinee calibration samples in which ability is widely dispersed.This work was supported by Contract No. N00014-83-C-0457, project designation NR 150-520, from Cognitive Science Program, Cognitive and Neural Sciences Division, Office of Naval Research and Educational Testing Service through the Program Research Planning Council.

Cross-Cultural Awareness: A Framework for Interaction

In order to facilitate cross-cultural understanding, a framework for interaction is provided by focusing on personal experience and on attrition theory and the W-curve,     

Specifying importance weights consistent with a covariance structure

Many situations exist in which multiple dimensions must be combined to create a composite which reflects overall utility or value to a decision maker. A linear combination is often used in which the decision maker's importance weights are multiplied by values of each dimension and then added. When the decision maker's weights are applied, however, the dimension values must have equal variance and essentially zero correlations, or else the ordering on the composite will be incorrect. In this paper, we provide a method which compensates for dimension correlation and inequality of dimension variance. The method is illustrated with ratings of modifications proposed for nuclear power plants.     

Predicting Units Needed for College Entrance

This article reports an example of guidance research to improve student decision-making. Each of 278 students in a recent high school graduating class in Palo Alto was classified according to the criterion of highest level of college (in terms of academic preparation required for entrance) by which he had been accepted. A correlation analysis indicated that the criterion could be predicted almost as accurately from test scores and grades available at the end of Grade 9 as from data available in grades 11 and 12. The criterion data and the 9th grade data were incorporated into an experience table for use by 9th graders in determining how rigorous a high school program a student would need for entrance into the highest level of college by which he might eventually be accepted. An additional analysis indicated that many of the poorer students took far more college preparatory courses than they needed for college entrance purposes.     

Specifying executive representations and processes in number generation tasks

The Interacting Cognitive Subsystems framework, ICS (Barnard, 1985) proposes that central executive phenomena can be accounted for by two autonomous subsystems, which process different forms of meaning: propositional and schematic (implicational) meanings. The apparent supervisory role of the executive arises from limitations on the exchange of information between these and other cognitive subsystems. This general proposal is elaborated in four experiments in which a total of 1,293 participants are asked to spontaneously generate a large verbal number to varying task constraints, with the intention of specifying the representations of number and task that underlie responses. Responses change systematically according to participants' use of explicit propositional information provided by the instructions, and inferred implicational information about what the experimenter is requesting. There was a high error rate (between 6% and 24%), participants producing responses that did not fall within the large range indicated by the instructions. The studies support the distinction between propositional and implicational processing in executive function, and provide a framework for understanding normal executive representations and processes.     

Specifying the Concept of Future Generations for Addressing Issues Related to High-Level Radioactive Waste

The nuclear community frequently refers to the concept of “future generations” when discussing the management of high-level radioactive waste. However, this notion is generally not defined. In this context, we have to assume a wide definition of the concept of future generations, conceived as people who will live after the contemporary people are dead. This definition embraces thus each generation following ours, without any restriction in time. The aim of this paper is to show that, in the debate about nuclear waste, this broad notion should be further specified and to clarify the related implications for nuclear waste management policies. Therefore, we provide an ethical analysis of different management strategies for high-level waste in the light of two principles, protection of future generations—based on safety and security—and respect for their choice. This analysis shows that high-level waste management options have different ethical impacts across future generations, depending on whether the memory of the waste and its location is lost, or not. We suggest taking this distinction into account by introducing the notions of “close future generations” and “remote future generations”, which has important implications on nuclear waste management policies insofar as it stresses that a retrievable disposal has fewer benefits than usually assumed.     

Specifying the Nature of Social Skill Deficits Associated With Depression

According to the social skill deficit theory of depression, people who lack social skills are unable to obtain positive social reinforcement and thus become depressed. However, past research is replete with mixed findings on the social skill-depression relationship. The present research was designed to overcome two prominent shortcomings in this research: poor operationalizations of social skill and constraining experimental procedures. In Study 1, 67 depressed and 74 nondepressed subjects engaged in an unstructured interaction with knowledge that they were being videotaped. In Study 2, 40 depressed and 61 nondepressed subjects were surreptitiously videotaped as they waited with another student for a study to begin. Analyses of subjects' social skill in these interactions indicated that depression is associated with a partial social skill deficit, most notable in terms of excessive social anxiety, low motivation to communicate with others, low social expressivity, and diminished behavioral involvement in Study 2. Partners of depressed subjects also showed low behavioral involvement in Study 2. However, on some aspects of social skill, depressed subjects appeared no different from their nondepressed peers. Depressed subjects' social skill was most deficient when they were given no instruction to interact and had no knowledge that they were being recorded.     

Specifying the impulsivity of female inmates with borderline personality disorder

Impulsivity is regarded as a core feature of borderline personality disorder (BPD; M. C. Zanarini, J. G. Gunderson, & F. R. Frankenburg, 1989) despite lack of evidence from laboratory research (D. M. Dougherty, J. M Bjork, H. C. G. Huckabee, F. G. Moeller, & A. C. Swann, 1999). This study examined impulsivity in incarcerated women with BPD using a passive avoidance task (J. P. Newman & W. A. Schmitt, 1998) and the Impulsiveness-Monotony Avoidance-Detachment inventory (IMD; D. Schalling, 1978). As predicted, incarcerated women diagnosed with BPD committed more passive avoidance errors and reported more impulsivity on the IMD than controls. These findings identify disinhibition as a potentially important component of the impulsivity that characterizes BPD. Specifying the impulsive behavior identified with BPD may contribute to the effective assessment and management of the disorder.     

A Scoring Scheme for the TAT and other Verbal Projective Techniques

Summaiy: Three groups of subjects rated each item in Rotter's I-E Scale for its social desirability value. Social desirability scale values (SDSV) of paired items were compared with one another. Results indicated that paired items are not sufficiently similar in their SDSVs, thus enabling subjects to respond on the basis of social desirability. All three groups rated internal items as being significantly more socially desirable than external items. The correlations between the SDSV ratings of the three groups were highly significant. The results indicate that the scale, as it is currently used, is seriously deficient.     

Enacted Others: Specifying Goffman's Phenomenological Omissions and Sociological Accomplishments

Erving Goffman's distinctive contribution to an understanding of others was grounded in his information control and ritual models of the interaction process. This contribution centered on the forms of the interaction order rather than self-other relations as traditionally conceived in phenomenology. Goffman came to phenomenology as a sympathetic but critical outsider who sought resources for the sociological mining of the interaction order. His engagement with phenomenological thinkers (principally Gustav Ichheiser, Jean-Paul Sartre and Alfred Schutz) has to be understood in these terms. The article traces basic differences in analytical focus through a range of phenomenological critiques of Goffman and a comparison of salient aspects of Schutz's and Goffman's writings. While the contrasts have perhaps been overplayed, I conclude that Goffman's thinking about others probably owed more to his pragmatist roots than to his later encounters with phenomenology.Earlier versions of this paper were presented at the Annual Meeting of the Society for Phenomenology and the Human Sciences in 1992 and 2003. I am grateful to discussions with participants at both meetings, which helped to clarify my ideas on a number of the paper's themes.     

Specifying what makes a personal memory unique enhances emotion regulation

During recollection of past experiences, the way autobiographical information is processed affects the intensity of the emotion aroused. Two main hypotheses were proposed in this respect: One focuses on the type of information activated during retrieval; the second is centered on the mode of processing at work. This article defends the notion that both perspectives need to be integrated to predict emotional arousal during autobiographical recollection. The authors explored the consequences on emotional feeling intensity by manipulating the type of information processed, together with the cognitive mode activated (specific vs. general level of processing). Results support previous findings that voluntarily specifying memories reduces emotional intensity. However, this was observed only when the details that make the event unique were processed.
