How career variety promotes the adaptability of managers: A theoretical model

This paper presents a theoretical model showing how managerial adaptability develops from career variety over the span of the person’s career. By building on the literature of career theory, adult learning and development, and career adjustment, we offer a new conceptualization of managerial adaptability by identifying its behavioral, cognitive, and socio-emotional dimensions, discuss how these competencies can develop from the variety of managers’ cumulative career experiences, and propose several individual and career-related factors that moderates the relationship between managerial career variety and adaptability.     

An essay on inequalities and order-restricted inference

This essay was prompted by a concern on the part of many senior members of the Society for Mathematical Psychology that the training of contemporary cognitive scientists exhibits a trend away from quantitative sophistication. Such a trend, if it goes unchallenged, can only serve to further marginalize mathematical psychology. There are several ways to combat this disturbing situation. Members of the Society might involve themselves more vigorously with scientific problems that are widely viewed as substantively or methodologically important, problems that require technical skill for their resolution; one example, discussed here, concerns order-restricted inference. We can also do more to encourage graduate students to develop and explore sophisticated theoretical models by giving them the tools to do so; that last battle must take place in the classroom.     

Mathematical Pluralism: The Case of Smooth Infinitesimal Analysis

A remarkable development in twentieth-century mathematics is smooth infinitesimal analysis (‘SIA’), introducing nilsquare and nilpotent infinitesimals, recovering the bulk of scientifically applicable classical analysis (‘CA’) without resort to the method of limits. Formally, however, unlike Robinsonian ‘nonstandard analysis’, SIA conflicts with CA, deriving, e.g., ‘not every quantity is either = 0 or not = 0.’ Internally, consistency is maintained by using intuitionistic logic (without the law of excluded middle). This paper examines problems of interpretation resulting from this ‘change of logic’, arguing that standard arguments based on ‘smoothness’ requirements are question-begging. Instead, it is suggested that recent philosophical work on the logic of vagueness is relevant, especially in the context of a Hilbertian structuralist view of mathematical axioms (as implicitly defining structures of interest). The relevance of both topos models for SIA and modal-structuralism as appled to this theory is clarified, sustaining this remarkable instance of mathematical pluralism.     

Event-related potentials and the decision to shoot: The role of threat perception and cognitive control

Participants played a videogame in which they were required to make speeded shoot/don’t-shoot decisions in response to armed and unarmed targets, half of whom were Black, half of whom were White. Event-related brain potentials (ERPs), recorded during the game, assessed attentional processes related to target race and object type. Early ERP components (i.e., the P200 and N200) differentiated between Black and White targets, as well as between armed and unarmed targets. Explicitly measured cultural stereotypes predicted both this racial ERP differentiation and racial bias in the game. Most importantly, the degree of racial differentiation in the early ERP components predicted behavioral bias in the videogame and mediated the relationship between cultural stereotypes and bias.     

Analytical methods in the theory of psychophysical discrimination II: The Near-miss to Weber's Law, Falmagne's Law, the Psychophysical Power Law and the Law of Similarity

We examine the possibility of accounting for an empirical phenomenon in auditory psychophysics called the “Near-Miss to Weber's Law” [Jesteadt, W., Weir, C., & Green, D. (1977). Intensity discrimination as a function of frequency and sensation level. Journal of the Acoustical Society of America, A, 61, 169-177], within the framework of Fechner's Psychophysics. To this end, we introduce a pair of Psychophysical Laws governing the behavior of Weber sensitivities. One of these, the Power Law, embodies ideas that Jesteadt et al. introduced in their original discussion of the near-miss phenomenon. Falmagne's Law captures ideas of Falmagne and colleagues [Falmagne, J.-Cl. (1985). Elements of psychophysical theory. New York: Oxford University Press; Doble, C., Falmagne, J.-Cl., & Berg, B.G. (2003). Theoretical note: Recasting (the near-miss to) Weber's Law. Psychological Review, 110, 365-375]. These two laws, which account for the near-miss phenomenon in quite different ways, are shown to be special cases of a more general Psychophysical Law of Similarity. We find all (smooth) solutions of this Law of Similarity that are compatible with Fechnerian psychophysics. Of the 11 solutions, four are relevant to the near-miss phenomenon; two of these solutions reproduce the models of Jesteadt et al. and Doble et al. and the other two solutions each provide a new accounting of the near-miss phenomenon. We discuss the possibility of distinguishing among these four models in empirical data.     

Attachment and sensitivity in family context: the roles of parent and infant gender

This study examined the role of child gender in fathers' and mothers' sensitivity to and attachment relationships with their infants from a family systems perspective. Eighty‐seven 1‐year‐olds participated in the Strange Situation with each parent. Parental sensitivity was examined during a competing demands task. Results indicated that fathers and mothers were equally sensitive to sons, but fathers were less sensitive than mothers to daughters, and mothers were more sensitive to daughters than to sons. Although mothers and fathers within the same families were similarly sensitive to daughters and sons, daughters' attachment security with fathers and mothers was similar whereas sons' was not. Further analyses revealed that fathers were more sensitive to sons with an insecure relationship with their mothers. Results of this investigation suggest that child gender is relevant for parent–infant, especially father–infant, attachment relationships. Copyright © 2006 John Wiley & Sons, Ltd.     

The social‐psychological bases of far‐right support in Europe and the United States

The roles of authoritarianism, social dominance orientation (SDO), and prejudice in the prediction of far‐right support were examined in Europe and the United States. A meta‐analysis shows remarkably similar, positive, and strong associations of far‐right support with these three variables in previous studies conducted in Europe, the United Kingdom, and the United States. Results from two cross‐sectional studies in the United States further indicated that higher levels of authoritarianism and SDO related to higher voting intentions and support for Trump, via increased prejudice. In a three‐wave longitudinal study in the United Kingdom, authoritarianism and SDO predicted pro‐Brexit attitudes and support for the U.K. Independence Party, again via prejudice. These results shed a new light on the widely held beliefs in “American and British exceptionalism,” as Trump and Brexit adherents share the same social‐psychological underpinnings as far‐right supporters observed in several European countries.     

ICD-11 guidelines for psychotic,mood, anxiety and stress-related disorders in Mexico: Clinical utility and reliability

Background/Objective: The World Health Organization's diagnostic guidelines for ICD-11 mental and behavioural disorders must be tested in clinical settings around the world to ensure that they are clinically useful and genuinely global. The objective is evaluate the inter-rater reliability and clinical utility of ICD-11 guidelines for psychotic, mood, anxiety- and stress-related disorders in Mexican patients. Method: Adult volunteers exhibiting the selected symptoms were referred from the pre-consultation unit of a public psychiatric hospital to an interview by a pair of clinicians, who subsequently assigned independent diagnoses and evaluated the clinical utility of the diagnostic guidelines as applied to each particular case, on the basis of a scale developed for this purpose. Results: 23 clinicians evaluated 153 patients. Kappa scores were strong for psychotic disorders (.83), moderate for stress-related (.77) and mood disorders (.60) and week for anxiety and fear-related disorders (.43). A high proportion of clinicians considered all diagnostic guidelines to be quite to extremely useful as applied to their patients. Conclusions: ICD-11 guidelines for psychotic, stress-related and mood disorders allow adequate inter-rater consistency among Mexican clinicians, who also considered them as clinical useful tools.
