How and why does a metaphor work? What happens to us when we hear or read one? My guess is that a metaphor, because it is an erroneous statement, conflicts with our expectations. It releases, triggers, and stimulates our predisposition to detect error and to take corrective action. We do not dismiss or reject a metaphor as simply a false statement for we recognize it as a metaphor and know as [Donald] Davidson suggests that it alludes to something else that (...) we might wish to notice. It preempts our attention and propels us on a quest for the underlying truth. We are launched into a creative, inventive, pleasurable act. To turn Piaget around, to invent is to understand. For the hearer or reader of a metaphor to detect, by himself, the nature of the error and to invent his own version of the truth entails understanding and achievement and thus pleasure. Such pleasure perhaps owes its origin to, and is enhanced by an echo from, the metaphoric playfulness of childhood. A metaphor is a peremptory invitation to discovery. What is discoverable are the various allusive ties, or common attributes, between the metaphor and the underlying truth to which it points. It is plausible to guess that the pleasure, and hence power, of the metaphor depends on two factors. It is the more powerful and effective the greater the number of allusive ties discovered and the greater the speed or suddenness with which the discoveries are made. A metaphor that packs all of its allusions into one or a few words should be more effective than a metaphor on which the same allusions are scattered throughout a long chain of words or sentences. The number of allusive ties in some sense reflects how close the metaphor approaches the truth—how near it is to being on target. Perhaps the closer it is, the more compelling the urge to correct the error—like the pull of a magnet. Don R.

In recent years there has been an increased awareness with regards to ethics in business. More specifically, the abundance of well-publicized examples of cheating, greed, and hypocrisy has created some alarm about the general state of personal ethics. Recent examples include the Oliver North, Ivan Boesky, and Jimmy Swaggart cases. The tax practitioner probably has little direct concern for matters of misconduct and ethical improprieties as mentioned above. Adherence to a code of conduct appears to circumvent the ethical conflict typically (...) found in the business environment. The tax practitioner's ultimate goal is tax minimization for clients. This goal has the blessings of the courts and the writers of tax law.The present day dynamic global economic system includes organizations which have extensive international activity. In an effort to enhance the performance of these organizations, there is typically decentralization of operations. When decentralization exists it is necessary to evaluate the decentralized units. Profit centers are commonly used for this purpose. With profit centers comes the need for transfer pricing between profit centers. The transfer price should be determined in some objective fashion. However, tax minimization often is the driving force in the transfer price decision. (shrink)

This article presents an approach to understanding human spatial competence that focuses on the representations and processes of spatial cognition and how they are integrated with cognition more generally. The foundational theoretical argument for this research is that spatial information processing is central to cognition more generally, in the sense that it is brought to bear ubiquitously to improve the adaptivity and effectiveness of perception, cognitive processing, and motor action. We describe research spanning multiple levels of complexity to understand both (...) the detailed mechanisms of spatial cognition, and how they are utilized in complex, naturalistic tasks. In the process, we discuss the critical role of cognitive architectures in developing a consistent account that spans this breadth, and we note some areas in which the current version of a popular architecture, ACT-R, may need to be augmented. Finally, we suggest a framework for understanding the representations and processes of spatial competence and their role in human cognition generally. (shrink)

Watching another person in pain activates brain areas involved in the sensation of our own pain. Importantly, this neural mirroring is not constant; rather, it is modulated by our beliefs about their intentions, circumstances, and group allegiances. We investigated if the neural empathic response is modulated by minimally-differentiating information (e.g., a simple text label indicating another’s religious belief), and if neural activity changes predict ingroups and outgroups across independent paradigms. We found that the empathic response was larger when participants viewed (...) a painful event occurring to a hand labeled with their own religion (ingroup) than to a hand labeled with a different religion (outgroup). Counterintuitively, the magnitude of this bias correlated positively with the magnitude of participants’ self-reported empathy. A multivariate classifier, using mean activity in empathy-related brain regions as features, discriminated ingroup from outgroup with 72% accuracy; the classifier’s confidence correlated with belief certainty. This classifier generalized successfully to validation experiments in which the ingroup condition was based on an arbitrary group assignment. Empathy networks thus allow for the classification of long-held, newly-modified and arbitrarily-formed ingroups and outgroups. This is the first report of a single machine learning model on neural activation that generalizes to multiple representations of ingroup and outgroup. The current findings may prove useful as an objective diagnostic tool to measure the magnitude of one’s group affiliations, and the effectiveness of interventions to reduce ingroup biases. (shrink)

This collection of essays on themes in the work of John Locke , George Berkeley , and David Hume , provides a deepened understanding of major issues raised in the Empiricist tradition. In exploring their shared belief in the experiential nature of mental constructs, The Empiricists illuminates the different methodologies of these great Enlightenment philosophers and introduces students to important metaphysical and epistemological issues including the theory of ideas, personal identity, and skepticism. It will be especially useful in courses devoted (...) to the history of modern philosophy. (shrink)

This paper critically examines the claim that parallel distributed processing (PDP) networks are autonomous learning systems. A PDP model of a simple distributed associative memory is considered. It is shown that the 'generic' PDP architecture cannot implement the computations required by this memory system without the aid of external control. In other words, the model is not autonomous. Two specific problems are highlighted: (i) simultaneous learning and recall are not permitted to occur as would be required of an autonomous system; (...) (ii) connections between processing units cannot simultaneously represent current and previous network activation as would be required if learning is to occur. Similar problems exist for more sophisticated networks constructed from the generic PDP architecture. We argue that this is because these models are not adequately constrained by the properties of the functional architecture assumed by PDP modelers. It is also argued that without such constraints, PDP researchers cannot claim to have developed an architecture radically different from that proposed by the Classical approach in cognitive science.

We focus on two issues: (1) an unusual, counterintuitive prediction that quantum probability (QP) theory appears to make regarding multiple sequential judgments, and (2) the extent to which QP is an appropriate and comprehensive benchmark for assessing judgment. These issues highlight how QP theory can fall prey to the same problems of arbitrariness that Pothos & Busemeyer (P&B) discuss as plaguing other models.

In most decision-making situations, there is a plethora of information potentially available to people. Deciding what information to gather and what to ignore is no small feat. How do decision makers determine in what sequence to collect information and when to stop? In two experiments, we administered a version of the German cities task developed by Gigerenzer and Goldstein (1996), in which participants had to decide which of two cities had the larger population. Decision makers were not provided with the (...) names of the cities, but they were able to collect different kinds of cues for both response alternatives (e.g., “Does this city have a university?”) before making a decision. Our experiments differed in whether participants were free to determine the number of cues they examined. We demonstrate that a novel model, using hierarchical latent mixtures and Bayesian inference (Lee & Newell, 2011) provides a more complete description of the data from both experiments than simple conventional strategies, such as the take–the–best or the Weighted Additive heuristics.

The ethical issues in conducting research on preventing HIV infection are among the most complex of any area of human subjects research. This article is an update of a 1987 article that addressed potential conflicts between research design and ethics with respect to AIDS prevention among injecting drug users. The present article reviews current ethical issues that arise in the design and conduct of HIV/AIDS prevention research focused on injecting drug users.

Many new mothers question the nature of their motherly love after birth. This affectionate relationship towards the infant is commonly called bonding in everyday speech, clinical practice and research. Bonding may not sufficiently describe the mother’s emotional response to the infant and does not capture the ambivalence and struggle to develop maternal affection of many women. This study aims to explore the phenomenon of disturbed maternal affection through the clinical case of one mother who experienced severe and prolonged disturbances. Two (...) in-depth interviews led to a descriptive phenomenological analysis. The mother developed depressive symptoms from not feeling enough for her child, not the opposite, as is often hypothesized. We describe and discuss crucial constituents of her experience, such as ambivalence, remoteness, boredom, guilt, and the looming repetition of parenting patterns, and a solution resulting from therapy-enhanced reflection on motherhood vis-à-vis early life patterns, sociocultural expectations and existential predicaments.
