Word length effect in early reading and in developmental dyslexia

Vocal reaction times were measured in Italian dyslexics and in proficient readers while they read single words. Three groups of control participants (for a total of 79) were tested. All were in the first, second or third grade of elementary school. Nine third graders with a low level of reading ability when assessed by standard reading procedures were also tested. Results indicated that vocal RTs of control participants were faster and less sensitive to word length as a function of age; also, there was a particularly marked change between first and second graders. Dyslexics' vocal RTs and errors were much worse than those of peer control participants and resembled those of first grade controls. It is suggested that normal readers in an orthographically transparent language (Italian) adopt a lexical strategy quite early in their learning. On the contrary, dyslexics seem unable to learn this mode of processing and continue to use a sub-lexical reading procedure.     

The spontaneous use of a group typology as an organizing principle in memory

Five studies investigated the spontaneous use of group typology in encoding information about various social groups. Participants saw faces or behaviors along with a label indicating the group membership of the face or the behavior. Labels corresponded to 2 groups each of 3 group types (i.e., 2 intimacy groups, 2 task-oriented groups, and 2 social categories). Recognition results showed more within-group-type errors than between-group-types errors. A free-recall task replicated these results, as the sequence of remembering items showed that memory organization reflected the group typology. A final study investigated the effects of group typology on the speed and accuracy of category membership verification. Results demonstrate the spontaneous use of an implicit group typology and its influence on the cognitive organization of information about groups.     

Self-regulation in early childhood: the interplay between family risk,temperament and teacher–child interactions

Abstract

This study investigates the interplay between family risk and the quality of classroom interactions and their impact on self-regulation skills in two groups of children—children from socioeconomically disadvantaged backgrounds (at-risk) and non-risk children. Participants included 485 children (N = 93 classrooms)—233 (N = 47 classrooms) of which were from socioeconomically disadvantaged areas. Temperament was measured using teacher report. Trained observers rated classroom quality via live observations of a typical preschool day. Behavioral regulation was assessed using direct measures and emotional regulation was assessed using a teacher report. Analyses using multiple group structural equation modeling showed that at-risk children had lower levels of cool behavior regulation than non-risk children. In addition, classroom quality was positively linked to cool behavioral self-regulation. Moderating effects were additionally found between family risk and classroom quality on both hot behavioral regulation and emotional regulation. Classroom quality served as a protective factor for children exposed to more risk factors. Results showed complex associations between individual characteristics, classroom quality, and family risk, indicating a need to further explore the interplay among these variables.     

Individual and Collective Intentionality: Elaborating the Fundamentality-Question

This is a contribution to the controversy which of individual or collective intentionality is more fundamental. I call it the fundamentality-question. In a first step, I argue that it is really two questions. One is about sense and one about reference. The first is: Can one grasp or understand the concept individual intentionality and, correspondingly, individuality, on the one hand, without grasping or understanding the concept collective intentionality and, correspondingly, collectivity, on the other? The second is: Can the concept individual intentionality and corresponding concept of individuality, on the one hand, refer to something without the concept of collective intentionality and corresponding concept of collectivity referring to something, on the other? Simplifying somewhat, this elaborated fundamentality-question admits of nine answers. In a second step, I pursue a tentative answer to the elaborated fundamentality-question. Given a disambiguation of individuality and, correspondingly, individual intentionality, the answer is the combination of claims that individuality and individual intentionality in one sense is fundamental in reference-dependence but that collectivity and collective intentionality is fundamental in reference-dependence in the other sense of individuality, while collectivity and collective intentionality is in both cases fundamental in sense-dependence.

     

Knowing about not remembering: developmental dissociations in lack‐of‐memory monitoring

Children aged 7 and younger encounter great difficulty in assessing whether lack of memory for an event indicates that the event was not experienced. The present research investigated whether this difficulty results from a general inability to evaluate memory absence or from a specific inability to monitor one feature of memory absence that has been examined in previous studies, namely expected memorability. Seven‐, 8‐ and 9‐year‐olds, and adults (N = 72) enacted, imagined and confabulated about bizarre and common actions. Two weeks later, participants were asked to recognize the actions that had been enacted. Even 7‐year‐olds monitored the relative familiarity of rejected distracters (i.e. reported higher confidence for the rejection of novel versus imagined and confabulated distracters). However, only older children and adults exhibited the ability to monitor expected memorability (e.g. reported higher confidence for the rejection of bizarre versus common distracters). These results suggest that young children exhibit specific, rather than general, deficits in monitoring memory absence, and provide an indication of the specific domains in which lack‐of‐memory monitoring improves during childhood.     

‘Three is better than two’: Increasing donations with the attraction effect

Five experiments (N_total = 2,503) tested the attraction effect and its boundary conditions in the context of helping behaviour. Participants could choose one donation appeal in a set of either two or three alternatives. The three alternatives set included a decoy – an alternative that resembled but was clearly inferior to a target (i.e., the most beneficial) alternative. A clear and consistent pattern emerged: Participants chose the target alternative more frequently and perceived it as more beneficial (and somewhat less costly) when the decoy was present compared to when it was absent. This finding was robust when the attribute ratings of the alternatives were unclear, when the target alternative offered a bundle of unrelated products, and when participants could refrain from donating altogether, or contribute any amount they wished. Our findings offer concrete and simple strategies that charities can implement at zero cost to increase giving and the perceived benefits that people’s good deed bring about to those in need.
