Ethical decision-making research has centered on Rest’s framework that represents a rational, nonaffective model for ethical decision making. However, research in human cognition suggesting a “dual-processing” framework, composed of both rational and affective components, has been relatively ignored in the ethical decision-making literature. Examining dual-processing literature, it seems affect might be an important factor in decision making when a person’s mood is congruent with the task or situational context frame. Given that ethical decisions are serious and complex tasks, it is (...) |

Research on innovation often highlights analogies from sources outside the current problem domain as a major source of novel concepts; however, the mechanisms underlying this relationship are not well understood. We analyzed the temporal interplay between far analogy use and creative concept generation in a professional design team's brainstorming conversations, investigating the hypothesis that far analogies lead directly to very novel concepts via large steps in conceptual spaces . Surprisingly, we found that concepts were more similar to their preceding concepts (...) |

The paper focuses on the embodied view of cognition applied to language. First we discuss what we intend when we say that concepts are “embodied”. Then we briefly explain the notion of simulation, addressing also its neuro-physiological basis. In the main part of the paper we will focus on concepts mediated by language, presenting behavioral and neuro-physiological evidence of the action/perception systems activation during words and sentences comprehension. |

Using a cross-modal semantic priming paradigm, both experiments of the present study investigated the link between the mental representations of iconic gestures and words. Two groups of the participants performed a primed lexical decision task where they had to discriminate between visually presented words and nonwords (e.g., flirp). Word targets (e.g., bird) were preceded by video clips depicting either semantically related (e.g., pair of hands flapping) or semantically unrelated (e.g., drawing a square with both hands) gestures. The duration of gestures (...) |

Previous research has shown implicit semantic processing of faces or pictures, but whether symbolic carriers such as words can be processed this way remains controversial. Here we examine this issue by adopting the continuous flash suppression paradigm to ensure that the processing undergone is indeed unconscious without the involvement of partial awareness. Negative or neutral words projected into one eye were made invisible due to strong suppression induced by dynamic-noise patterns shown in the other eye through binocular rivalry. Inverted and (...) |

The performance of symbolic inference tasks has long been a challenge to connectionists. In this paper, we present an extended survey of this area. Existing connectionist inference systems are reviewed, with particular reference to how they perform variable binding and rule- based reasoning and whether they involve distributed or localist representations. The bene®ts and disadvantages of different representations and systems are outlined, and conclusions drawn regarding the capabilities of connectionist inference systems when compared with symbolic inference systems or when used (...) |

A central aim of Construction Grammar is to model links within the construct-i-con. This paper investigates three constructions that share one property: an atypical element in the object slot. The constructions are therefore not prototypically transitive. Structural priming (implemented with an automatic maze variant of self-paced reading) is used to test hypotheses on the relation among the Reaction Objoid (She smiled her thanks), the Cognate Objoid (She smiled a sweet smile or He told a sly tale), and the Superlative Objoid (...) |

The field of cognition and emotion is characterised as the cognitive psychology of evaluative and affective processes. The most important development in this field is the fruitful adoption of cognitive psychology paradigms to study automatic evaluation processes, for example. This has led to a plethora of findings and theories. Two points are emphasised: First, the (often metaphorical) theoretical way of thinking has changed over the decades. Theorising with symbolic models (e.g. semantic networks), which was prevalent in earlier years, has been (...) |

The contents and structure of semantic memory have been the focus of much recent research, with major advances in the development of distributional models, which use word co‐occurrence information as a window into the semantics of language. In parallel, connectionist modeling has extended our knowledge of the processes engaged in semantic activation. However, these two lines of investigation have rarely been brought together. Here, we describe a processing model based on distributional semantics in which activation spreads throughout a semantic network, (...) |

Our response to this symposium on our 2006 paper centers on three questions. First, what motivations exist in the political wild, and do our experimental manipulations realistically capture them? We agree that strong accuracy motivations are likely (but not certain) to reduce biases, but we are not at all confident that the real world supplies stronger accuracy motivations than our subjects received. Second, how can we square our findings of stubbornly persistent beliefs and attitudes with the well-established literatures on framing (...) |

The Influence of Emotional and Non-emotional Concepts Activation on Information Processing and Unintentional Memorizing The aim of the work is to compare mechanisms of semantic and emotional processing and memory. Targets were primed by category name. The congruency of prime and target was manipulated. The reaction time of lexical decisions and the effects of unintentional memorizing of word targets were measured. Activation of semantic and emotional nodes leads to faster processing of related concepts: congruent targets are processed faster than incongruent. (...) |

According to Mednick’s (1962) theory of individual differences in creativity, creative individuals appear to have a richer and more flexible associative network than less creative individuals. Thus, creative individuals are characterized by “flat” (broader associations) instead of “steep” (few, common associations) associational hierarchies. To study these differences, we implement a novel computational approach to the study of semantic networks, through the analysis of free associations. The core notion of our method is that concepts in the network are related to each (...) |

Semantic priming has long been recognized to reflect, along with automatic semantic mechanisms, the contribution of controlled strategies. However, previous theories of controlled priming were mostly qualitative, lacking common grounds with modern mathematical models of automatic priming based on neural networks. Recently, we introduced a novel attractor network model of automatic semantic priming with latching dynamics. Here, we extend this work to show how the same model can also account for important findings regarding controlled processes. Assuming the rate of semantic (...) |

The syntagmatic paradigmatic model is a distributed, memory‐based account of verbal processing. Built on a Bayesian interpretation of string edit theory, it characterizes the control of verbal cognition as the retrieval of sets of syntagmatic and paradigmatic constraints from sequential and relational long‐term memory and the resolution of these constraints in working memory. Lexical information is extracted directly from text using a version of the expectation maximization algorithm. In this article, the model is described and then illustrated on a number (...) |

Most Artificial Intelligence theories of language either assume a syntactic component which serves as “front end” for the rest of the system, or else reject all attempts at distinguishing modules within the comprehension system. In this paper we will present an alternative which, while keeping modularity, will account for several puzzles for typical “syntax first” theories. The major addition to this theory is a “marker passing” (or “spreading activation”) component, which operates in parallel to the normal syntactic component. |

Variable binding has long been a challenge to connectionists. Attempts to perform variable binding using localist and distributed connectionist representations are discussed, and problems inherent in each type of representation are outlined. |

Findlay and Lumsden have proposed a model of creative potential which accounts for divergent thinking but not for convergent thinking. This limitation impedes the applicability of the model to scientific creativity, where competence and thus convergent thinking play a fundamental role since the early stages of creation. This limitation is a natural consequence of the fact that Findlay and Lumsden's model is purely intrapsychic. This paper proposes a model of scientists' creative potential which accounts for both divergent and convergent processes. (...) |

This article draws attention to a pattern of development within science and other intellectual research communities that has received virtually no mention. We propose that subsequent dominance of a research community by a figure responsible for significant innovation often delays progress in the field. During the period in which the revolutionary continues to influence research in a community, far too frequently the effect is to freeze progress within the limited directions which the revolutionary sanctions. |
