Assessing Working Memory Capacity Through Time-Constrained Elementary Activities

Working memory (WM) capacity measured through complex span tasks is among the best predictors of fluid intelligence (Gf). These tasks usually involve maintaining memoranda while performing complex cognitive activities that require a rather high level of education (e.g., reading comprehension, arithmetic), restricting their range of applicability. Because individual differences in such complex activities are nothing more than the concatenation of small differences in their elementary constituents, complex span tasks involving elementary processes should be as good of predictors of Gf as traditional tasks. The present study showed that two latent variables issued from either traditional or new span tasks involving time-constrained elementary activities were similarly correlated with Gf. Moreover, a model with a single unitary WM factor had a similar fit as a model with two distinct WM factors. Thus, time-constrained elementary activities can be integrated in WM tasks, permitting the assessment of WM in a wider range of populations.     

Moore's Proof And Martin Davies's Epistemic Projects

In the recent literature on Moore's Proof of an external world, it has emerged that different diagnoses of the argument's failure are prima facie defensible. As a result, there is a sense that the appropriateness of the different verdicts on it may depend on variation in the kinds of context in which the argument is taken to be a move, with different characteristic aims. In this spirit, Martin Davies has recently explored the use of the argument within two different epistemic projects called respectively ‘deciding what to believe’ and ‘settling the question’. Depending on which project is in hand, according to Davies, the diagnoses of its failure—if indeed it fails—will differ. I believe that, by introducing the idea that the effectiveness of a valid argument may be epistemic project-relative, Davies has pointed the way to an important reorientation of the debates about Moore's Proof. But I wish to take issue with much of the detail of his proposals. I argue that Davies's characterization of his two projects is misleading (§1), and his account of their distinction defective (§2). I then canvass some suggestions about how it may be improved upon and about how further relevant kinds of epistemic projects in which Moore's argument may be taken to be a move can be characterized, bringing out how each of these projects impinges differently on the issue of the Proof's failure and of its diagnosis (§§3 and 4). In conclusion (§5) I offer an overview of the resulting terrain.     

Right—left prevalence effect with horizontal and vertical effectors

We investigated the right-left prevalence effect in spatial compatibility tasks by assessing subjects’ performance on a two-dimensional task in which both the horizontal and vertical spatial dimensions were task relevant. Two experiments were performed, in which stimulus-response mappings were one-dimensional (Experiment 1) and two-dimensional (Experiment 2). The subjects responded by using either horizontal or vertical effectors to stimuli appearing in four possible locations. With the one-dimensional mapping, the spatial compatibility effect was present only in the dimension relevant to the mapping. With the two-dimensional mapping, the horizontal compatibility effect was always present, whereas the vertical compatibility effect was present only when vertical effectors were used. This pattern of results indicates that horizontal coding takes place with either horizontal or vertical effectors, whereas vertical coding takes place only when vertical effectors are used.     

Stopping points: ‘I’, immunity and the real guarantee

Abstract

The aim of the paper is to bring out exactly what makes first-personal (and more generally indexical and demonstrative) contents special, by showing that they perform a distinctive cognitive function. Namely, they are stopping points of inquiry. First, I articulate this idea and then I use it to clear the ground from a troublesome conflation. That is, the conflation of this particular function all first-person thoughts have with the property of immunity to error through misidentification, which only some I-thoughts enjoy. Afterward, I show the implications of this idea for a theory of first-person content and of immunity to error though misidentification. I then make some comparisons with Pryor’s notion of wh-misidentification and immunity thereof and with Cappelen and Dever’s position on immunity to error through misidentification and show why they are defective.     

Eye movement desensitization and reprocessing as a therapeutic intervention for traumatized children and adolescents: a systematic review of the evidence for family therapists

Eye movement desensitization and reprocessing (EMDR) is a relatively new form of psychotherapy for post‐traumatic symptoms of relevance to systemic therapists. The literature available on individual EMDR in traumatized children is reviewed in this article. A sample of eight studies was examined, consisting of three controlled trials, two uncontrolled studies and three case reports or series. The controlled trials compared EMDR with waiting list controls or cognitive behavioural therapy (CBT). The study samples were small and their methodological quality variable. In all the studies, the results suggested a positive effect for EMDR but did not appear superior to CBT. It is therefore possible that systemic interventions may be improved by the integration of EMDR and family therapy with children and adolescents.     

Sexual harassment under social identity threat: the computer harassment paradigm

Two laboratory experiments investigated the hypothesis that threat to male identity would increase the likelihood of gender harassment. In both experiments, using the computer harassment paradigm, male university students (N=80 in Experiment 1, N=90 in Experiment 2) were exposed to different types of identity threat (legitimacy threat and threat to group value in Experiment 1 and distinctiveness threat and prototypicality threat in Experiment 2) or to no threat and were then given the opportunity to send pornographic material to a virtual female interaction partner. Results show that (a) participants harassed the female interaction partner more when they were exposed to a legitimacy, distinctiveness, or prototypicality threat than to no threat; (b) this was mainly true for highly identified males; and (c) harassment enhanced postexperimental gender identification. Results are interpreted as supporting a social identity account of gender harassment.     

Factor Analysis of the Italian Version of the Alabama Parenting Questionnaire in a Community Sample

Despite difficulties measuring parenting styles, many studies have demonstrated a significant relationship between disruptive children and certain parenting practices. One of the most frequently used scales to measure parenting styles is the Alabama Parenting Questionnaire (APQ). This scale was originally defined based on theoretical dimensions and using samples from the USA. Therefore, both factor analysis studies and its adaptation to other countries have been proposed to improve and widen its use. The aim of this study was to adapt the APQ to the Italian population. A community sample of 258 mothers and children (94 %) and 192 fathers (70 %) from 274 families with children from 10- to 14-years-old who agreed to participate and met the inclusion criteria completed the APQ. Principal components and exploratory factor analyses resulted in a unique 19-item version of the APQ for mothers, fathers, and children. This unified version has resulted in two factor categories: positive (12 items) and negative parenting (7 items). The internal consistency and goodness of fit of the model were satisfactory. Moderate and significant convergent validity were found for mothers and fathers but not for children. In fact, we found differences in validity rates among the participants. Children perceived less positive and more negative parenting than did fathers and mothers, and mothers believed that they provided more positive parenting than did other parents. In conclusion, the APQ Italian version of the parents and children global report forms are considered a suitable measure for positive and negative parenting styles with acceptable validity and reliability indices.
