Working memory limits are best defined in terms of the complexity of the relations that can be processed in parallel. Complexity is defined as the number of related dimensions or sources of variation. A unary relation has one argument and one source of variation; its argument can be instantiated in only one way at a time. A binary relation has two arguments, two sources of variation, and two instantiations, and so on. Dimensionality is related to the number of chunks, because (...) both attributes on dimensions and chunks are independent units of information of arbitrary size. Studies of working memory limits suggest that there is a soft limit corresponding to the parallel processing of one quaternary relation. More complex concepts are processed by or In segmentation, tasks are broken into components that do not exceed processing capacity and can be processed serially. In conceptual chunking, representations are to reduce their dimensionality and hence their processing load, but at the cost of making some relational information inaccessible. Neural net models of relational representations show that relations with more arguments have a higher computational cost that coincides with experimental findings on higher processing loads in humans. Relational complexity is related to processing load in reasoning and sentence comprehension and can distinguish between the capacities of higher species. The complexity of relations processed by children increases with age. Implications for neural net models and theories of cognition and cognitive development are discussed. (shrink)

The core issue of our target article concerns how relational complexity should be assessed. We propose that assessments must be based on actual cognitive processes used in performing each step of a task. Complexity comparisons are important for the orderly interpretation of research findings. The links between relational complexity theory and several other formulations, as well as its implications for neural functioning, connectionist models, the roles of knowledge, and individual and developmental differences, are considered.

This paper discusses using the Chernobyl Incident as a case study in engineering ethics instruction. Groups of students are asked to take on the role of a faction involved in the Chernobyl disaster and to defend their decisions in a mock debate. The results of student surveys and the Engineering and Science Issues Test indicate that the approach is very popular with students and has a positive impact on moral reasoning. The approach incorporates technical, communication and teamwork skills and has (...) many of the features suggested by recent literature. (shrink)

Informed by this premise the book explores some of the key questions in criminal theory, addressing first the ethics of criminalisation and punishment.

In a rational system defences should interlock with the elements of the offence to ensure that conviction labels are differentiated according to the defendant’s degree of wrongdoing and culpability. The overall grading structure of criminal homicide, as represented in contemporary doctrine, goes some way to reflect this ethic. But the substance lacks precision and, in some key details, moral coherence. The recent Law Commission Consultation Paper, in a pragmatic and sensible attempt to rid the law and procedure of murder of (...) the malign influence of the mandatory sentence, has unnecessarily compromised such structural coherence as it currently enjoys and which could properly form a satisfactory basis for reform already precise and morally coherent. This is evident both in relation to the abandonment of the attack based template for the fault element in murder, and also in the unwillingness to view the partial defences as affecting the wrong in homicide as opposed to the grade.

Cowan's review shows that a short-term memory limit of four items is consistent with a wide range of phenomena in the field. However, he does not explain that limit, whereas an existing theory does offer an explanation for capacity limitations. Furthermore, processing capacity limits cannot be reduced to storage limits as Cowan claims.

We propose that the missing link from nonhuman to human cognition lies with our ability to form, modify, and re-form dynamic bindings between internal representations of world-states. This capacity goes beyond dynamic feature binding in perception and involves a new conception of working memory. We propose two tests for structured knowledge that might alleviate the impasse in empirical research in nonhuman animal cognition.

Selected writings from the most influential texts of the samurai era—in a pocket-size edition. The samurai of Japan, who were the country's military elite from medieval times to the end of the nineteenth century, were synonmous with valor, honor, and martial arts prowess. Their strict adherence to the code of bushido ("the way of the warrior"), chivalry, and honor in fighting to the death continues to capture the imagination of people today, inspiring authors, filmmakers, and artists. The Pocket Samurai contains (...) the essential writings of the era by the most esteemed samurai and philosophers of the age, including the iconic Miyamoto Musashi, author of The Book of Five Rings; Yamamoto Tsunetomo, author of Hagakure, the best-known explication of the samurai code; Takuan Soho, the Zen priest and adviser to samurai; Yagyu Munenori, whose The Life-Giving Sword describes a deeply spiritual approach to sword fighting; and others.
