This paper reports on the use of the construction toy LEGO as an effective learning resource for undergraduate classes in the psychology of creativity. Students first attended a short series of lectures on aspects of creativity, including learner characteristics such as motivation and metacognition, and theoretical approaches to problem-finding and problem-solving including the Geneplore model ...

Although many attempts have been made to enable creative and effective design activities using a computer, many design activities depend on the designer’s personal ability and are learned through interpersonal communication. These limitations are thought to be due to the fact that the knowledge we use does not cover the entire design process, comprising the problem-forming process and the probl...

Recent research on the crossmodal integration of visual and auditory perception suggests that evaluations of emotional information in one sensory modality may tend toward the emotional value generated in another sensory modality. This implies that the emotions elicited by musical stimuli can influence the perception of emotional stimuli presented in other sensory modalities, through a top-down ...

The relationship between a theory of learning and a theory of instruction is discussed. Examples are presented that illustrate how to proceed from a theoretical description of the learning process to the specification of an optimal strategy for carrying out instruction. The examples deal with fairly simple learning tasks and are admittedly of limited generality. Nevertheless, they clearly defin...

A key difficulty in Cooperative Coevolutionary Algorithms (CCEAs) is the credit assignment problem[1]. One solution to the credit assignment problem is the difference evaluation function, which produces excellent results in many multiagent domains. However, to date, there has been no prescriptive theoretical analysis deriving conditions under which difference evaluations improve the probability...

Existing methods for constructive induction usually isolate feature generation from problem solving, and do not exploit information about the purpose for which features are created. This paper describes a theory of feature generation that creates features using both a domain theory and feedback from a concept learner. An evaluation function can then be learned using these features that is able ...

The following problem is considered: given a Boolean formula f, generate another formula g such that: (i) If f is unsatisfiable then g is also unsatisfiable. (ii) If f is satisfiable then g is also satisfiable and furthermore g is “easier” than f. For the measure of this easiness, we use the density of a formula f which is defined as (the number of satisfying assignments)/2n, where n is the num...

Three experiments were conducted to investigate the short-term use of supplementary Trp on the behavior of grow/finish pigs. Three levels of dietary Trp were used, representing the standard requirement for growth (control), twice (2x), and 4 times (4x) the control amount. In Exp. 1, pigs were fed the diets for 7 d, during which observations were made of their general behavior (time budget), agg...

How does the scattering cross section change when the colliding bound-state fragments are allowed particle-emitting resonances? This question is explored in the framework of a multichannel algebraic scattering method of determining nucleon-nucleus cross sections at low energies. Two cases are examined, the first being a gedanken investigation in which n + 12C scattering is studied with the targ...
