Connexive Logic, Probabilistic Default Reasoning, and Compound Conditionals
2023
We present two approaches to investigate the validity of connexive principles and related formulas and properties within coherence-based probability logic. Connexive logic emerged from the intuition that conditionals of the form if not-A, then A, should not hold, since the conditional’s antecedent not-A contradicts its consequent A. Our approaches cover this intuition by observing that the only coherent probability assessment on the conditional event A | not-A is p(A | not-A) = 0. In the first approach we investigate connexive principles within coherence-based probabilistic default reasoning, by interpreting defaults and negated defaults in terms of suitable probabilistic constraints on con…
Logical Operations among Conditional Events: theoretical aspects and applications
2019
We generalize the notions of conjunction and disjunction of two conditional events to the case of $n$ conditional events. These notions are defined, in the setting of coherence, by means of suitable conditional random quantities with values in the interval $[0,1]$. We also define the notion of negation, by verifying De Morgan's Laws. Then, we give some results on coherence of prevision assessments for some families of compounded conditionals and we show that some well known properties which are satisfied by conjunctions and disjunctions of unconditional events are also satisfied by conjunctions and disjunction of conditional events. We also examine in detail the coherence of the prevision a…
Probabilistic inference and syllogisms
2014
Traditionally, syllogisms are arguments with two premises and one conclusion which are constructed by propositions of the form “All S are P ” and “At least one S is P ” and their respective negated versions. We will discuss probabilistic notions of the existential import and the basic sentences type. We will develop an intuitively plausible version of the syllogisms that is able to deal with uncertainty, exceptions and nonmonotonicity. We will develop a new semantics for categorical syllogisms that is based on subjective probability. Specifically, we propose de Finetti’s principle of coherence and its generalization to lower and upper conditional probabilities as the fundamental corner ston…
Majority and minority influence, task representation and inductive reasoning
1996
One hundred and fifty-five participants had to solve a set of 2–4–6 like reasoning problems (Wason, 1960), in which they were told which hypothesis a majority (or a minority) proposed, as well as which example was used for the test. In a 2 × 2 design, participants were also told that the problems allowed either one single correct answer or several possible answers. Results show that, when the source is a majority and the problem allows one single answer, most participants adopt the source's hypothesis and use confirmatory testing. On the contrary, it is when the source is a minority and the problem allows several answers that most participants give alternative hypotheses and use disconfirma…
The longitudinal relations among dimensions of parenting styles, sympathy, prosocial moral reasoning, and prosocial behaviors
2010
Developmental scholars assert that parents are important in fostering prosocial behaviors in adolescents, but longitudinal investigations on this topic are limited. Participants consisted of 372 boys and 358 girls with a mean age of 10.84 years (SD = 1.57) at Wave 1 from a mostly middle class community in Spain. Across three successive years, participants completed measures of fathers’ and mothers’ warmth and strict control, sympathy, prosocial moral reasoning, and self- and peer-reported prosocial behaviors. Results showed that parental warmth, sympathy, and prosocial moral reasoning were predictive of prosocial behaviors. Further analyses showed bidirectional effects such that early proso…
El síndrome del cromosoma X Frágil: fenotipo conductual y dificultades de aprendizaje
2015
In this article, we describe the behavioral phenotype of individuals with Fragile X Syndrome and its impact in the educational scope. This syndrome is characterized by difficulties in sensory integration, cognitive deficits (verbal reasoning, abstract/ visual and cuantitative skills, short term memory, sequential processing, attention and executive processes), language disorders (phonetic-phonologicals, semanticals, morphosyntacticals and pragmaticals) and communication disorders, social anxiety, general hyperarousal, autism, non autistic social difficulties, attention deficit and hyperactivity, and learning disabilities. The behavioral phenotype is highly variable and depends on sex, age, …
Examining the predictors of prosocial behavior in young offenders and nonoffenders
2021
Research on young offenders has primarily focused on identifying predictors of the maladaptive, aggressive behavior; there is a scarcity of evidence on factors that relate to prosocial behavior in these adolescents. The current study examined the link from parenting, emotional instability, and prosocial reasoning to prosocial behavior, while also examining the mediating roles of empathic concern (EC) and perspective taking (PT) in a sample of Spanish adolescent offenders compared to a sample of nonoffenders. Participants were 440 adolescents: 220 young offenders residing in four Youth Detention Centres of Valencia (67.3% men) and 220 enrolled in public and private schools within the metrop…
Placement of responsibility and moral reasoning in couple therapy
2005
Within the past two decades there has been a growing awareness of the importance of moral and ethical judgements in family and couple therapy. In this article we provide a detailed analysis of placements of responsibility related to blame in one couple therapy session. We suggest that it is important to study therapeutic interaction in situ, when searching for an understanding of moral reasoning in couple therapy and an ethical evaluation of the practice. A detailed analysis of discursive tools used by clients and therapists makes it possible to look at moral reasoning in action as it unfolds within the flow of therapeutic conversation. The findings are discussed in relation to two discours…
A Comparison of Dyadic and Social Network Assessments of Peer Influence.
2021
The present study compares two methods for assessing peer influence: the longitudinal actor–partner interdependence model (L-APIM) and the longitudinal social network analysis (L-SNA) Model. The data were drawn from 1,995 (49% girls and 51% boys) third grade students ( Mage= 9.68 years). From this sample, L-APIM ( n = 206 indistinguishable dyads and n = 187 distinguishable dyads) and L-SNA ( n = 1,024 total network members) subsamples were created. Students completed peer nominations and objective assessments of mathematical reasoning in the spring of the third and fourth grades. Patterns of statistical significance differed across analyses. Stable distinguishable and indistinguishable L-AP…
PROSOCIAL MORAL REASONING AND PROSOCIAL BEHAVIOR AMONG TURKISH AND SPANISH ADOLESCENTS
2012
Due to copyright restrictions, the access to the full text of this article is only available via subscription. Prosocial moral reasoning and behavior of young people in early and middle adolescence were examined in relation to the association among the variable of cultural group, age, and gender. Adolescents from Valencia, Spain (673 boys, 579 girls) and Ankara, Turkey (185 boys, 145 girls) participated in this study. Results showed significant cultural group differences on both prosocial moral reasoning subscales and peer rating of prosocial behavior with Spanish adolescents scoring higher than Turkish adolescents, and in the pattern of relationships between these variables. There were als…
