The illusion of replacement in research into the development of thinking biases: the case of the conjunction fallacy

The conjunction fallacy is a violation of a very basic rule of probability. Interestingly, although committing the fallacy seems irrational, adults are no less susceptible to the fallacy than young children. In Experiment 1, by employing tasks where the conjunctive response option involved two non-representative items, we found a large reduction in fallacy rates as compared to traditional conjunction fallacy problems. Nevertheless, fallacy rates remained relatively high in both adolescents and adults, although adults showed more consistency in their normative responses. In Experiment 2, we demonstrated that children’s relatively good performance on the task was not the consequence of their missing knowledge of social stereotypes. Additionally, children were more strongly affected by explicitly presented frequency information than adults. Indeed, adults only took frequency information into account when frequencies were made relevant by a training in probabilistic reasoning. Overall, the results suggest that whereas the potential for normative reasoning increases with development, this potential is often overshadowed by a pervasive tendency in adolescence and adulthood to rely on contextual information, knowledge, and beliefs, even when conflicting information is available. By contrast, children are more strongly influenced by explicitly presented information than relevant knowledge cued by the tasks.     

The assessment of knowledge and learning in competence spaces: The gain–loss model for dependent skills

The gain–loss model (GaLoM) is a formal model for assessing knowledge and learning. In its original formulation, the GaLoM assumes independence among the skills. Such an assumption is not reasonable in several domains, in which some preliminary knowledge is the foundation for other knowledge. This paper presents an extension of the GaLoM to the case in which the skills are not independent, and the dependence relation among them is described by a well‐graded competence space. The probability of mastering skill s at the pretest is conditional on the presence of all skills on which s depends. The probabilities of gaining or losing skill s when moving from pretest to posttest are conditional on the mastery of s at the pretest, and on the presence at the posttest of all skills on which s depends. Two formulations of the model are presented, in which the learning path is allowed to change from pretest to posttest or not. A simulation study shows that models based on the true competence space obtain a better fit than models based on false competence spaces, and are also characterized by a higher assessment accuracy. An empirical application shows that models based on pedagogically sound assumptions about the dependencies among the skills obtain a better fit than models assuming independence among the skills.     

Belief,trust, and relationality: a Simmelian approach for the study of faith

Religion has been conceptualised as personal belief in the transcendent. Anthropologists of religion have critiqued such a construct for decades for being based on a Christian Protestant model and one that reflected subsequently modern rationalist Western culture. This construct has increasingly been shown to fail to account for the religiosity of contemporary Christians. Drawing on the sociology of Georg Simmel and based on ethnographic research in a Christian evangelical church, the article proposes a reconceptualisation of religious belief that is experiential and relational. Evangelicals in this case study show that propositional belief plays increasingly a secondary role to belief intended as trust in God and forming a relationship with God and others. Relationships mediate personal religious experience and are shown to be essential to the conversion process, the life of faith, and Christian identity. The study thus bridges the separation between theoretical and empirical works by operationalising Simmel’s sociology.     

Age-related trends in Stroop and conflicting motor response task findings.

Inhibition problems are reportedly at the heart of several childhood pathologies and learning disorders, but few instruments are available for their in-depth investigation. The main aim of the present study was to investigate the development of a capacity to inhibit automatic responses in young and middle childhood. For this purpose, 100 children between 6 and 11 years old were administered two tests that measure executive inhibition: an animal Stroop task (in a paper-and-pencil version of the computerized original proposed by Wright and colleagues in 2003) and a conflicting motor response task. Our results indicate that performance clearly improves in both tests during the course of a child's development and the data obtained with the paper-and-pencil animal Stroop task overlap with those obtained with the computerized version. When the task calls for a stronger inhibitory control (the incongruent situation in the Stroop task and in the opposite condition in the conflicting motor response test) the trend of the response times is less homogeneous, peaking in the youngest and oldest age brackets considered. The positivity and significance of the correlation coefficients between the two tests also suggest that the two measures are tapping cognitive abilities that are developing in a parallel fashion.     

Simultaneous and sequential Feature Negative discriminations: Elemental learning and occasion setting in human Pavlovian conditioning

Using a conditioned suppression task, we investigated simultaneous (XA−/A+) vs. sequential (X → A−/A+) Feature Negative (FN) discrimination learning in humans. We expected the simultaneous discrimination to result in X (or alternatively the XA configuration) becoming an inhibitor acting directly on the US, and the sequential discrimination in X becoming a negative occasion setter acting indirectly on the A-US link. After simultaneous FN training, X+ training completely abolished discriminative XA/A responding (Experiment 1), and X transferred inhibition to new targets B regardless of their training history (B+ or YB−/B+) (Experiment 2), suggesting X became a simple inhibitor. After sequential FN training, X showed the predicted selective transfer to a target B that also had been modulated (Y → B−/B+), not to a simple excitor (B+) (Experiment 4), but turning X into an excitor (X+) likewise disrupted discriminative X → A/A responding (Experiment 3). This suggests that X acquired a combination of modulatory and direct inhibitory properties, and that the joint contribution of both components is necessary for the suppression of the target-induced US activation.     

The Determinants of Subjective Economic Well-being: An Analysis on Italian-Silc Data

Using Italian data on Income and living conditions for the year 2005, the paper investigates the main determinants of households’ subjective economic well-being by means of a Partial Proportional Ordered Logit Model. According to a joint subjective and objective perspective of analysis, we use as dependent variable the perceived ability of households to make ends meet. Whereas, we use as explanatory variables some objective aspects of living conditions relating to housing, financial equilibrium, possession of durables and quality of residence place and some socio-demographic characteristics. The empirical results show that the financial strain is the most relevant dimension of living conditions influencing the subjective economic well-being, but its effect is attenuated depending on the level of education and the tenure status of accommodation. Actually, when the highest levels of education are coupled with the status of self-employee and house-owner households have more chances to reach a higher probability to be economically satisfied. The insights coming out from the results may call for different policy measures depending on the degree of well-being and the characteristics of households. In particular, more efficient policies would be oriented to sustain the households’ income, to encourage to buy a house and to allow young people to get the highest levels of education.     

The neuropsychological correlates of cognitive insight in healthy participants

Cognitive insight is the ability to monitor and correct one's own erroneous convictions. The Beck Cognitive Insight Scale (BCIS) assesses two sub‐dimensions of cognitive insight: self‐reflectiveness (SR), which is the attitude of questioning one's own judgments; and self‐certainty (SC), which is the unwillingness to modify and correct one's own convictions. There is little information about cognitive insight in healthy participants (HP). Here we investigated the socio‐demographic and neuropsychological correlates of cognitive insight in 50 HP who were administered the BCIS and a comprehensive neuropsychological battery. The global BCIS R‐C index correlated positively with age and WCST perseverative errors. SR correlated positively with age. These data support the hypothesis that a less self‐reflective and more self‐confident style is cognitively functional in HP. Thus, what has been found malfunctioning in mental illnesses is adaptive in HP. Future studies should consider a wider range of factors that might affect this complex construct.

Affect, unconscious and sensemaking. A psychodynamic, semiotic and dialogic model

The work presents a psychodynamic, semiotic and dialogical model of affect and of the role it plays in sensemaking. The model is based on the following three general assumptions.A) Affective semiosis works in accordance to the dynamic unconscious which Freud conceptualized in terms of primary process. According to this interpretation, the unconscious is the mind’s homogenising way of functioning, which transforms every categorical relation into a relation of identity. B) Affect is the generalized, homogenising and absolutizing embodied basic intersubjective meanings according to which experience is interpreted. C) Affective semiosis performs both the grounding and regulative functions in sensemaking, orienting the way people interpret experience.     

Three Students with Developmental Disabilities Learn to Operate an iPod to Access Age-Appropriate Entertainment Videos

Students with developmental disabilities may not have the necessary skills or the same opportunities to access multimedia-based leisure materials as their typical peers. Portable multimedia devices such as the iPod Touch® may provide them with a useful tool for accessing age-appropriate leisure material. The present study examined the feasibility of teaching 3 students with developmental disabilities to independently operate an iPod to watch age-appropriate entertainment videos. A delayed multiple-probe design across participants was implemented with baseline, intervention, fading, and follow-up phases. Video modeling and least-to-most response prompting were successfully used to teach these 3 students to operate an iPod Touch® to watch preferred videos without adult assistance. The results complement previous findings supporting the use of video modeling as an instructional strategy and add to the literature by using portable multimedia devices as assistive technology for teaching an age-appropriate leisure skill.     

Newborns' preference for goal-directed actions

The central role of sensory-motor representations in cognitive functions is almost universally accepted. However, determining the link between motor execution and its sensory counterpart and when, during ontogenesis, this link originates are still under investigation. The aim of the present study is to investigate whether at birth this link is already present and 2-day-old newborns are able to discriminate between visual cues indicating goal-directed or non-goal-directed actions. Here, with a preferential looking technique, a hand grasping a ball was the observed movement and we orthogonally manipulated the three factors necessary to successfully reach the goal: (a) presence of the ball, (b) direction of the arm movement, and (c) hand shaping. Results indicated that newborns orient more frequently and look longer at a hand shape for whole hand prehension but only when the movement is directed away from the body and toward the external world. In addition, newborns prefer the away from the body movement only when the object is present. We argue that newborns prefer a movement directed toward the external world only when it may develop into a purposeful movement because of the presence of the to-be-grasped object. Overall, our results support the existence of primitive sensory-motor associations since the first days after birth.
