Chronometric evidence for memory retrieval in causal conditional reasoning: The case of the association strength effect
2005
According to many models of conditional reasoning, correct responses to the uncertain forms affirmation of consequent (AC) and denial of antecedent (DA) rely on the retrieval of an alternative antecedent from semantic memory. The main prediction issuing from this hypothesis of online retrieval is that the associative strength of the relevant information in long-term memory affects the latency of its retrieval and then of the correct response of uncertainty to AC and DA. This prediction was tested in 64 adults who performed a syllogism evaluation task with familiar causal conditional premises. As predicted, correct responses of uncertainty to AC and DA were not only more frequent but also fa…
Facilitating Effect of Natural Frequencies: Size Does Not Matter
2009
The question of whether humans are able to work in a Bayesian way is currently a topic of substantial investigation. An important finding, reported by Gigerenzer and Hoffrage in 1995 is that Bayesian reasoning is facilitated when the information format corresponds to natural frequencies. The present concern was whether the facilitating effect of frequencies persists when natural frequencies relate to samples which are not convenient multiples of 10. 150 undergraduates participated as volunteers (42 men, 108 women; M age = 23 yr.). Analysis showed the effect of natural frequency formats was not dependent on size of reference class. Theoretical and practical implications are discussed.
Moral reasoning and moral conflict in patients of the amyotrophic lateral sclerosis – Frontotemporal dementia spectrum
2020
The aim of this study was to investigate the moral reasoning and moral conflict in patients of the amyotrophic lateral sclerosis – frontotemporal dementia (ALSFTD) spectrum. Ten ALS patients without cognitive impairment, 10 ALS patients with cognitive or behavioral impairment, 10 ALSFTD patients and 23 controls were examined with neuropsychological and behavioral tests as well as with a set of eight well -designed moral dilemmas. The responses to the moral dilemmas were used as proxies to evaluate interpersonal moral reasoning. Reactivity to change, reaction time and arousal were used as markers of moral conflict. ALSFTD patients showed more “utilitarian” responses and less moral conflict t…
VBM-DTI correlates of verbal intelligence: a potential link to Broca's area.
2012
Abstract Human brain lesion studies first investigated the biological roots of cognitive functions including language in the late 1800s. Neuroimaging studies have reported correlation findings with general intelligence predominantly in fronto-parietal cortical areas. However, there is still little evidence about the relationship between verbal intelligence and structural properties of the brain. We predicted that verbal performance is related to language regions of Broca's and Wernicke's areas. Verbal intelligence quotient (vIQ) was assessed in 30 healthy young subjects. T1-weighted MRI and diffusion tensor imaging data sets were acquired. Voxel-wise regression analyses were used to correla…
Feelings or cognitions? Moral cognitions and emotions as longitudinal predictors of prosocial and aggressive behaviors
2010
Abstract There is debate regarding the roles of sociomoral cognitions and emotions in understanding moral development. The short-term longitudinal relations among perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors and aggression in adolescents were examined. Participants were 489 students ( M age = 12.28 years, SD = .48; 232 boys) in public and private schools from predominantly middle class families in Valencia, Spain. Students completed measures of perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors, and aggressive behaviors. Overall, structural equation modeling analyses showed that moral reasoning and emotions were interrelated and pre…
Violence, exclusion and the role of children and adolescents moral features in the sport domain: The save project
2019
The prevention of violence and exclusion in the sport domain is one of the principal priorities of the European Union Programs. Sport Against Violence and Exclusion (SAVE) Project is an initiative co-founded by the Erasmus Plus Programme of the European Commission, whose aim is to train coach to recognize and manage violent and exclusion episodes in the sport situation. According to the psychological literature, one of the predictors of aggressiveness and antisocial tendencies is morality. In particular, for what concerns children, a less mature moral reasoning is associated to a greater tendency to aggress, while for adolescents, the moral atmosphere, in particular, the perception of the c…
Inductive synthesis of dot expressions
2005
We consider the problem of the synthesis of algorithms by sample computations. We introduce a formal language, namely, the so-called dot expressions, which is based on a formalization of the intuitive notion of ellipsis (‘...’). Whilst formally the dot expressions are simply a language describing sets of words, on the other hand, it can be considered as a programming language supporting quite a wide class of programs. Equivalence and asymptotical equivalence of dot expressions are defined and proved to be decidable. A formal example of a dot expression is defined in the way that, actually, it represents a sample computation of the program presented by the given dot expression. A system of s…
Designed Examples as Mediating Tools: Introductory Algebra in Two Norwegian Grade 8 Classrooms
2019
A critical element in the introduction of algebra is to focus student attention on the basic ideas of algebraic reasoning including the use of concepts such as variable and algebraic expression. In the Norwegian classrooms, representing a student-centered instructional philosophy, the teachers utilized examples and problems that they themselves had designed, and the examples involved resources such as concrete objects and body movements in order to make algebra accessible to students. When designing these examples, teachers thus used their own previous experiences of teaching algebra in an attempt to articulate the passage from arithmetic to algebra.
On Inductive Generalization in Monadic First-Order Logic With Identity
1966
Publisher Summary The chapter examines the results obtained by means of a system when the relation of identity is used in addition to monadic predicates. The chapter compares the new system of inductive logic sketched by Jaakko Hintikka with Carnap's system. The main advantage of Hintikka's system is that it gives natural degrees of confirmation to inductive generalizations, whereas Carnap's confirmation function c * enables one to deal satisfactorily with singular inductive inference only. According to Carnap's system, general sentences that are not logically true receive nonnegligible degrees of confirmation only if the evidence contains a large part of the individuals in the whole univer…
Closedness properties in team learning of recursive functions
1997
This paper investigates closedness properties in relation with team learning of total recursive functions. One of the first problems solved for any new identification types is the following: “Does the identifiability of classes U1 and U2 imply the identifiability of U1∪U2?” In this paper we are interested in a more general question: “Does the identifiability of every union of n−1 classes out of U1,...,Un imply the identifiability of U1∪...∪Un?” If the answer is positive, we call such identification type n-closed. We show that n-closedness can be equivalently formulated in terms of team learning. After that we find for which n team identification in the limit and team finite identification t…
