This chapter discusses the Ontogeny Phylogeny Model (OPM), which focuses on the formation and development of second language phonological systems. It proposes an interrelationship between L2 native-like productions, L1 transfer, and universal factors. The model argues that chronologically, and as style becomes increasingly formal, L2 native-like processes increase, L1 transfer processes decrease, and universal processes increase and then decrease. It further claims that the roles of universals and L1 transfer are mediated by markedness and similarity, both of which slow L2 acquisition. Specifically, in similar phenomena L1 transfer processes persist, while in marked phenomena universal processes persist. The OPM also argues that these same principles obtain for learners acquiring more than one L2, monolingual and bilingual acquisition, and L1 attrition. In addition to the chronological stages and variation of the individual learner, the model claims that these relationships hold true for language variation and change, including pidgins and creoles.
Human creativity originates from brain cortical networks that are specialized in idea generation, processing, and evaluation. The concurrent verbalization of our inner thoughts during the execution of a design task enables the use of dynamic semantic networks as a tool for investigating, evaluating, and monitoring creative thought. The primary advantage of using lexical databases such as WordNet for reproducible information-theoretic quantification of convergence or divergence of design ideas in creative problem solving is the simultaneous handling of both words and meanings, which enables interpretation of the constructed dynamic semantic networks in terms of underlying functionally active brain cortical regions involved in concept comprehension and production. In this study, the quantitative dynamics of semantic measures computed with a moving time window is investigated empirically in the DTRS10 dataset with design review conversations and detected divergent thinking is shown to predict success of design ideas. Thus, dynamic semantic networks present an opportunity for real-time computer-assisted detection of critical events during creative problem solving, with the goal of employing this knowledge to artificially augment human creativity.
The question of whether extraterrestrials exist has driven both the search for extraterrestrial intelligence (SETI) and some attempts of messaging to extraterrestrial intelligence (METI). Nevertheless, no data-driven or theory-based behavioural policy has been suggested. Here we simulate a comprehensive set of human–extraterrestrial strategic interactions, modelled as two-by-two game-theoretic matrices. We examine a sample of possible outcomes by relying on the theory of subjective expected relative similarity (SERS), which takes into account both the expected payoffs and the extent of strategic similarity – the prospects of the opponent making identical choices. Simulation results suggest: focusing messaging efforts on signalling of complete strategic similarity, monitoring potential alien communications for similarity-indicating signals, and using risk-averse decision rules for policy planning and decision-making. The discussion puts forward three guidelines for METI initiatives and addresses the relevance of the findings to human conflict management.
Experience is the cornerstone of Epicurean philosophy and nowhere is this more apparent than in the Epicurean views about the nature, formation, and application of concepts. ‘The Epicureans on Preconceptions and Other Concepts’ by Gábor Betegh and Voula Tsouna aims to piece together the approach to concepts suggested by Epicurus and his early associates, trace its historical development over a period of approximately five centuries, compare it with competing views, and highlight the philosophical value of the Epicurean account on that subject. It is not clear whether, properly speaking, the Epicureans can be claimed to have a theory about concepts. However, an in-depth discussion of the relevant questions will show that the Epicureans advance a coherent if elliptical explanation of the nature and formation of concepts and of their epistemological and ethical role. Also, the chapter establishes that, although the core of the Epicurean account remains fundamentally unaffected, there are shifts of emphasis and new developments marking the passage from one generation of Epicureans to another and from one era to the next.
Inclusion of a decoy alternative dominated by a target option, but not its competitor, typically leads to increased choice for the target over the competitor, known as the attraction effect. However, the reverse sometimes occurs, known as the repulsion effect. This research tested factors that moderate the repulsion effect in preferential choice scenarios with numerical attributes. Experiment 1 used a between-subjects design with a small set of consumer products and demonstrated robust repulsion effects that did not depend on the relative similarity of the decoy and target. Experiments 2 and 4 used a more powerful within-subjects design along with an expanded set of products and showed that repulsion effects were generally enhanced when the decoy and target had more similar attributes; however, the moderating effect of decoy–target similarity appeared to be fragile and sensitive to stimulus presentation factors. These findings provided mixed support for the hypothesis that the target is tainted by its proximity to the decoy. Experiments 3 and 5 tested whether the extremity of values on the attribute favoring the target moderates the repulsion effect. The results demonstrated that repulsion is more likely when all the alternatives have extremely high values on the target’s better attribute. Extremity of attribute values on the dimension favoring the target may result in a categorical assessment along that dimension and shift focus to the attribute favoring the competitor as one way to foster the repulsion effect.
The retrieval of past instances stored in memory can guide inferential choices and judgments. Yet, little process-level evidence exists that would allow a similar conclusion for preferential judgments. Recent research suggests that eye movements can trace information search in memory. During retrieval, people gaze at spatial locations associated with relevant information, even if the information is no longer present (the so-called ‘looking-at-nothing’ behavior). We examined eye movements based on the looking-at-nothing behavior to explore memory retrieval in inferential and preferential judgments. In Experiment 1, participants assessed their preference for smoothies with different ingredients, while the other half gauged another person’s preference. In Experiment 2, all participants made preferential judgments with or without instructions to respond as consistently as possible. People looked at exemplar locations in both inferential and preferential judgments, and both with and without consistency instructions. Eye movements to similar training exemplars predicted test judgments but not eye movements to dissimilar exemplars. These results suggest that people retrieve exemplar information in preferential judgments but that retrieval processes are not the sole determinant of judgments.
In Chapter 5, we discuss the processing components that underlie the perspective-taking analogy that we articulated in Chapter 2. This analysis makes it clear that the retrieval of personal knowledge and experience is critical, and we review some of what is known about episodic retrieval and how it can be used in this context. In forming an analogy, one must be able to identify how elements of the story world are related to corresponding elements in one’s own experience. To understand this process, we discuss how readers must construct similarity relations. Finally, we discuss the mechanics of analogy formation per se and describe the notion of a structural mapping between the reader and the character that underlies the perspective-taking analogy. We close out Chapter 5 with a discussion of perspective-taking dynamics. This includes an illustration of how perspective taking can be driven by the events of the story world or evaluations of the character. As we make clear, perspective taking is an ongoing process that can unfold in a variety of ways over the course of reading a narrative.
This chapter explores interpersonal attraction, the subjective appeal of another person, which is often accompanied by a positive emotional reaction and an affiliative motivation for greater closeness to that person. This chapter organizes the many specific traits that enhance attraction in terms of characteristics that offer domain-general rewards (e.g., pleasure, self-esteem, belonging) and characteristics that advance specific evolutionary goals (e.g., survival, reproduction). The chapter then reviews the characteristics that are most consistently desirable, including physical attractiveness, social status, warmth/kindness, intelligence, proximity, familiarity, similarity, and reciprocity by reviewing relevant research findings, as well as exceptions and boundary conditions. The chapter ends with a review of how sociocultural factors, including the immediate situation, women’s reproductive cycles, and the broader relationship trajectories provide context for understanding romantic attraction.
Chapter 2: Linearly independent lists of vectors that span a vector space are of special importance. They provide a bridge between the abstract world of vector spaces and the concrete world of matrices. They permit us to define the dimension of a vector space and motivate the concept of matrix similarity.
Inductive reasoning involves using existing knowledge to make predictions about novel cases. This chapter reviews and evaluates computational models of this fundamental aspect of cognition, with a focus on work involving property induction. The review includes early induction models such as similarity coverage, and the feature-based induction model, as well as a detailed coverage of more recent Bayesian and connectionist approaches. Each model is examined against benchmark empirical phenomena. Model limitations are also identified. The chapter highlights the major advances that have been made in our understanding of the mechanisms that drive induction, as well as identifying challenges for future modeling. These include accounting for individual and developmental differences and applying induction models to explain other forms of reasoning.
Analogy is a core cognitive capacity encompassing basic similarity (“this is like that”), relational similarity (proportional analogies of the form A:B::C:x), and complex system mappings, in which the elements of one situation are structurally aligned with the elements of another. The latter permits complex inferences from a known source situation to a less familiar target situation. Because of its centrality in human thinking, analogy has been the subject of numerous computational modeling efforts. Models of similarity come from multiple traditions in cognitive science, including associationist approaches (such as connectionist models), “traditional” symbolic approaches (such as graph matching and production systems), and hybrid symbolic/connectionist approaches. This chapter reviews and evaluates several models from these various approaches in terms of their ability to simulate basic similarity, relational similarity, and system mapping.
This chapter provides an overview of approaches to formal modeling in the domain of categorization. The core psychological processes addressed by models are: generating a classification decision in response to a stimulus and constructing category representations based on supervised experience. A taxonomy is provided that organizes the formal models in terms of their use of a fixed, combined, or constructed approach to predicting categories under either a cue-based or item-based framework. The chapter gives in-depth coverage of a leading approach (exemplar models) as well as an emerging alternative: a constructed cue-based model (DIVA) that differs from competing accounts by learning to reconstruct the input features via sets of category-specific weights and using the degree of reconstructive success (i.e., goodness-of-fit to the category) to determine the likelihood of membership.
This chapter introduces the basic patterns of Chinese comparison sentences, emphasizing that there are no comparative adjectives in Chinese. Attention is drawn to the features of the special constructions of 比 bǐ and 跟 gēn constructions and their negation forms.
Sign systems help to create descriptive and depictive representations. Descriptive representations operate on symbols. They are based on conceptual analyses identifying objects or events as well as attributes and interrelations. Attributes and relations are ascribed by predications to entities according to syntactic rules resulting in so-called propositions (“idea units”). These propositions can be integrated into coherent semantic networks. Propositional representations are considered as mental structures which can be externalized in the form of spoken or written texts. Despite their informational incompleteness, descriptions have high representational power. Depictive representations are based on inherent commonalities between a representing object and the represented subject matter. The inherent commonalities can be based on similarity or analogy. These representations are complete with regard to a certain class of information. Due to their completeness and consistency and because information can be read off directly, depictive representations have high computational efficiency.
Chapter 5 examines how considerations of coherence manifest in the use of analogical reasoning by investor-state tribunals. In particular, it demonstrates through concrete examples and case studies that the persuasiveness and correctness of an arbitral award based on analogical reasoning depends on the degree of its internal coherence. It is argued that coherence in an analogical inference manifests in two ways. Firstly, in a methodological sense, coherence manifests itself in the way the adjudicator frames the legal question at issue and in the degree to which the analogy, as drawn, satisfies the elements of similarity, structural parallels, and purposiveness. Secondly, in a substantive sense, coherence manifests itself in the normative contextualisation of the legal question and in the moral appeal of the proposed interpretation derived from the analogy.
The representativeness heuristic suggests that similarity judgments provide a basis for judgments of likelihood. We use Tversky’s (1977) contrast model of similarity to design tests of this underlying mechanism. If similarity is used to judge likelihood, factors that are known to affect similarity should also affect judgments of likelihood. In two experiments, we manipulated two such factors described in the contrast model of similarity: the nature of the task and context effects. In a between-subject design, respondents assessed either similarity of fictive citizens of 15th century Florence, or the likelihood that they belonged to the same family. The factors that affected similarity also affected the likelihood judgments. These results support the assumption that similarity is an important contributor to judgments of likelihood.
The similarity principle is based on the acknowledgment that a river, if left alone for a sufficiently long time with fixed values of water and sediment discharge loads, will adjust its width, depth, slope, and meandering pattern in a certain manner. If the values of water and sediment discharge loads imposed on the river change are different, the adjustment will be made similarly. This chapter derives the hydraulic geometry using this principle of similarity.
Modelling the distributional semantics of such a morphologically rich language as Arabic needs to take into account its introflexive, fusional, and inflectional nature attributes that make up its combinatorial sequences and substitutional paradigms. To evaluate such word distributional models, the benchmarks that have been used thus far in Arabic have mimicked those in English. This paper reports on a benchmark that we designed to reflect linguistic patterns in both Contemporary Arabic and Classical Arabic, the first being a cover term for written and spoken Modern Standard Arabic, while the second for pre-modern Arabic. The analogy items we included in this benchmark are chosen in a transparent manner such that they would capture the major features of nouns and verbs; derivational and inflectional morphology; high-, middle-, and low-frequency patterns and lexical items; and morphosemantic, morphosyntactic, and semantic dimensions of the language. All categories included in this benchmark are carefully selected to ensure proper representation of the language. The benchmark consists of 45 roots of the trilateral, all-consonantal, and semivowel-inclusive types; six morphosemantic patterns (’af‘ala; ifta‘ala; infa‘ala; istaf‘ala; tafa‘‘ala; and tafā‘ala); five derivations (the verbal noun, active participle, and the contrasts in Masculine-Feminine; Feminine-Singular-Plural; Masculine-Singular-Plural); and morphosyntactic transformations (perfect and imperfect verbs conjugated for all pronouns); and lexical semantics (synonyms, antonyms, and hyponyms of nouns, verbs, and adjectives), as well as capital cities and currencies. All categories include an equal proportion of high-, medium-, and low-frequency items. For the purpose of validating the proposed benchmark, we developed a set of embedding models from different textual sources. Then, we tested them intrinsically using the proposed benchmark and extrinsically using two natural language processing tasks: Arabic Named Entity Recognition and Text Classification. The evaluation leads to the conclusion that the proposed benchmark is truly reflective of this morphologically rich language and discriminatory of word embeddings.
This article adds nuance to current understandings of the relationship between the populist leader and the public by using the concept of trust. Merging the literature on populism with the growing scholarship on trust from philosophy, psychology and other social sciences, it argues that following on from the populist leader’s appeals to similarity, the populist–public relationship involves an intertwining of two forms of public trust: the public’s trust in the populist and the public’s trust in itself (what we term ‘public self-trust’). Contrary to what political and constitutional theorists have recognized as a tension between public self-trust and the public’s trust in its political representatives, we contend based on the scholarship on trust that in the populist–public relationship these two forms of trust can be mutually reinforcing. This mutual reinforcement, we suggest, has the potential to create a positive feedback loop of public trust that, given the value of public trust to political leaders, empowers the populist.
This chapter gets into the techniques of data analytics, focusing on the three pillars of data mining, namely clustering, classification, and association rule mining, and how each can be used for cybersecurity. This chapter can be seen as a crash course in data mining. It begins with an understanding of the overall knowledge discovery and data mining process models and follows the elements of the data life cycle. This chapter outlines foundational elements such as measures of similarity and measures of evaluation. It outlines the landscape of various algorithms in clustering, classification, and frequent and rare patterns.
