The finding that women are attracted to men older than themselves whereas men are attracted to relatively younger women has been explained by social psychologists in terms of economic exchange rooted in traditional sex-role norms. An alternative evolutionary model suggests that males and females follow different reproductive strategies, and predicts a more complex relationship between gender and age preferences. In particular, males' preferences for relatively younger females should be minimal during early mating years, but should become more pronounced as the (...) male gets older. Young females are expected to prefer somewhat older males during their early years and to change less as they age. We briefly review relevant theory and present results of six studies testing this prediction. Study 1 finds support for this gender-differentiated prediction in age preferences expressed in personal advertisements. Study 2 supports the prediction with marriage statistics from two U.S. cities. Study 3 examines the cross-generational robustness of the phenomenon, and finds the same pattern in marriage statistics from 1923. Study 4 replicates Study 1 using matrimonial advertisements from two European countries, and from India. Study 5 finds a consistent pattern in marriages recorded from 1913 through 1939 on a small island in the Philippines. Study 6 reveals the same pattern in singles advertisements placed by financially successful American women and men. We consider the limitations of previous normative and evolutionary explanations of age preferences and discuss the advantages of expanding previous models to include the life history perspective.

After writing my response to the commentaries, I sat back and reflected on the fascination and frustration of work on this topic. There is the ancient fascination of trying to understand the nature of the sensory bridge linking us to the external world. Also, discussing the measurability of sensation brings to the surface concepts we use and take for granted when we are working in other areas of psychology; and it holds them before us for critical examination. The frustration lies (...) chiefly in the difficulty of formulating concepts clearly, in a way understood by all. At least when constructing the original Tower of Babel, workers hearing strange words knew that communication was not occurring. The psychophysical Tower of Babel sometimes has workers using the same words, but with different meanings. Much of my response is based on attempts to clarify concepts and clear up confusions.

According to Davey, generalized expectancy biases cause fearrelevant behavior and may complement Seligman's biological preparedness model. Expectancy biases do not explain the preparedness phenomenon, because such cognitive (or covert behavioral) processes are themselves controlled by social and other environmentally based contingencies. Davey's own examination of the importance of cross-cultural factors can show the relationship between FR stimuli and behavior without needing cognitive agency to explain the behavioral phenomenon.

Davey suggests that increased resistance to extinction of CRs conditioned to fear-relevant stimuli may be due to more persistent expectancies of the UCS following these stimuli. However, this viewpoint is contradicted by existing empirical evidence that fear-relevant CRs survive an extinction trials series producing extinction of expectancies whereas CRs conditioned to non-fear-relevant CSs do not.

Davey has failed to clarify the critical evidence that could corroborate the expectancy bias hypothesis and refute preparedness theory. Such a clarification is necessary because each theory could potentially allow for multiple distal and proximal influences on selective associations. Expectancies are not the only proximal mediators. Our recent findings indicate that affective response matching may be an additional factor promoting such associations.

This commentary focuses upon two issues raised by Davey's target article: (1) whether there are certain core features of stimuli we learn to fear, rather than specific types of objects or situations, which implies some element of innateness; and (2) whether expectancy biases serve to maintain rather than generate anxiety.

Posner & Raichle's (1994) book is a fascinating and readable account of the studies the authors have conducted on the localization of cognitive functions in the brain mainly using PET and EEC evoked potential methods. Our criticism concerns the underrepresentation of some imaging techniques (magnetoencephalography) and some forms of brain activity (spontaneous activity). Furthermore, the book leaves the reader with the impression that the brain only responds to external events.

We divided the many diverse comments on our book into categories. These are: theory, scope and goals of our project, methods, comments on specific anatomical areas, the concept of attention, consciousness and cognitive control, and finally other issues. Although many of the points of the critics are certainly well taken, we believe studies that have emerged since our book provide strong evidence that the general approach taken in our book is now yielding important new data on the relation of cognitive (...) processes to underlying brain activity.

This is an excellent book but it lacks a detailed presentation and formulation of images of memory. Positron emission tomography (PET) findings sometimes raise more enigmatic questions than they answer, with differences between studies and differences with established lesion evidence. Perhaps the book could have been more critical in its analysis of these enigmas, covering more of the basic issues and assumptions underlying PET research.

A mechanistic study of consciousness need not be confined to human complexity. Other animals also display key behaviors and responses that have long been intimately tied to the measure of consciousness in humans. Among them are some very well-defined and measurable endpoints: selective attention, sleep and general anesthesia. That these three variables associated with changes in consciousness might exist even in a fruit-fly does not necessarily imply that a fly is “conscious”, but it does suggest that some of the problems (...) central to the field of consciousness studies could be investigated in a model organism such as Drosophila melanogaster. Demonstrating suppression of unattended stimuli, which is central to attention studies in humans, is now possible in Drosophila by measuring neural correlates of visual selection. By combining such studies with an eventual understanding of suppression in other arousal states in the fly, such as sleep and general anesthesia, we might be unraveling mechanisms relevant to consciousness as well.

The primary argument against Rachlin's act-versus-pattern analysis of self-control is that it is wrong to think of a temptation as a solitary act while the alternative is conceived of as an element of a pattern. Either both are solitary acts or both are members of patterns, however different the patterns may be in their complexity and abstractness.

Toward a neurobiologically grounded approach to explaining self-control we discuss the case of a patient with a bilateral lesion in frontal ventromedial cortex. Patients with such lesions display a marked deficit in social decision making. Compared with an account that examines the causal antecedents of self-control, Rachlin's behaviorist approach seems lacking in explanatory strength.

Psychologists tend to examine their activities in experimentation with the same objective scientific attitude as they routinely assume in the experimental situation. A few psychologists have stepped outside this closed expistemic practice to undertake reflexive analysis of the psychologist in the laboratory. Three cases of such critical reflexive analysis are considered to better understand the strategies and consequences of confronting what Steve Woolgar has called ‘the horrors of reflexivity’. Reflexive work of William James, Horace Mann Bond, and Saul Rosenzweig are (...) examined: working in the early years of modern experimental psychology these scientists identified limitations in the dominant natural science model of experimentation. Attending to the scientist's own cognitions, social status, and unconscious processes respectively, James, Bond, and Rosenzweig criticized this natural science model and presented methodological and epistemic alternatives. The relative neglect of their constructive observations underscores the resistance to addressing psychology's reflexive dimensions. (shrink)

The reply to Kanterian offers a rebuttal of his central criticisms. It reaffirms the difference between Kant's arguments in the Aesthetic and at B 148-9; it rejects the alleged error of logic in Fischer's (and my) arguments; and it rejects Kanterian's reading of passages in the Preface (A xx-xxii) and of the Amphiboly. Beyond these specific points Kanterian assumes that Kant's project in the first Critique cannot be understood as a and so begs the question at issue.

A pair of arguments suggests that self-control is not properly conceptualized on the pattern/act/preference model Rachlin proposes. The first concerns the irrational following of personal rules. The second concerns scenarios in which behavioral patterns an agent deems good come into conflict.

We describe the emergence of a new field, Mind Brain and Education, dedicated to the science of learning, as well as the roles researchers, policy makers, and educators need to play in developing this collaborative effort. The article highlights the challenges that MBE faces and the strategy researchers and educators in Texas are developing to meet these challenges. In particular, through the creation of a Research Schools Network, educators and researchers are creating an infrastructure to identify and test ideas critical (...) to educators. This network builds on Dewey's laboratory school by creating new responsibilities and partnerships. To this end we identify four critical objectives: develop a clear vision; build trusting relationships; set a standard for rigorous research and scholarship; and, promote meaningful assessment tools.

Since its inception the ‘mindblindness’ theory of autism has greatly furthered our understanding of the core social-communication impairments in autism spectrum conditions . However, one of the more subtle issues within the theory that needs to be elaborated is the role of the ‘self’. In this article, we expand on mindblindness in ASC by addressing topics related to the self and its central role in the social world and then review recent research in ASC that has yielded important insights by (...) contrasting processes relating to both self and other. We suggest that new discoveries lie ahead in understanding how self and other are interrelated and/or distinct, and how understanding atypical self-referential and social-cognitive mechanisms may lead to novel ideas as to how to facilitate social-communicative abilities in ASC.
