Inherent directionality of “even if” counterfactual conditionals

In this research, we investigate whether semifactual conditionals such as “even if there had been an A, there would have been a B” are understood by thinking initially of the antecedent “A”, as was found with factual conditionals. The “inherent directionality” hypothesis assumes that for the comprehension of most relational statements, a presuppositional element (i.e. the “relatum”) is initially established. For “even if”, both terms could work as “relatum”. This is because on the one hand, people tend to infer “B” from “A” and “not-A” and, on the other hand, “B” could work as a pragmatic presupposition. In the present experiment, semifactual and factual conditionals were tested with a sentence-picture verification task. Results were consistent with the “inherent directionality” hypothesis: only “if then” factual conditionals, but not semifactuals, showed a preference for reasoning from the antecedent, with faster verifications.     

Obstacle Avoidance Increases Asymmetry of Crossing Step in Individuals With Parkinson's Disease and Neurologically Healthy Individuals

The authors' aim was to investigate gait asymmetry of crossing step during obstacle avoidance while walking in people with Parkinson's disease (PD) under and without the effects of dopaminergic medication. Thirteen individuals with PD and 13 neurologically healthy individuals performed 5 trials of unobstructed gait and 10 trials of obstacle crossing during gait (5 trials with each leg) and spatiotemporal parameters were analyzed. Obstacle crossing increased step duration of the crossing step for the most-affected or nondominant limb compared to the crossing step with the least-affected or dominant limb. Individuals with PD without the effects of medication increased step duration for the step with the least-affected limb compared to the step with the most-affected limb during obstacle crossing.     

The final chapter of Vygotsky's Thinking and Speech: A reader's guide

The seventh and last chapter of Vygotsky's Thinking and Speech (1934) is generally considered as his final word in psychology. It is a long chapter with a complex argumentative structure in which Vygotsky gives his view on the relationship between thinking and speech. Vygotsky's biographers have stated that the chapter was dictated in the final months of Vygotsky's life when his health was rapidly deteriorating. Although the chapter is famous, its structure has never been analyzed in any detail. In the present article we reveal its rhetorical structure and show how Vygotsky drew on many hitherto unrevealed sources to convince the reader of his viewpoint.     

Teacher Job Stress and Satisfaction in Urban Schools: Disentangling Individual-, Classroom-, and Organizational-Level Influences

Schools remain among the most frequent providers of children’s mental health services, particularly in low-income urban settings. Several decades of research have focused on training teachers to implement evidence-based interventions for minimizing disruptive behavior. Studies consistently demonstrate robust improvements in student behavior and learning; however, the impact on teachers’ work-related stress or satisfaction is not well understood. Six urban, high-poverty elementary schools were randomly assigned to a school mental health services model (Links to Learning; L2L) for referred, disruptive students or to services and professional development as usual (SAU). Teachers (n = 71, K-4 general education teachers) in L2L schools participated in professional development and consultation in two universal and two targeted interventions to reduce disruptive behaviors and promote learning. Teachers (n = 65) in SAU schools participated in professional development as usual. Multiple regression models examined teacher reports of individual-level self-efficacy, classroom-level student functioning, and school-level organizational health as predictors of stress and satisfaction. Findings revealed no significant difference between conditions on teacher work-related stress or satisfaction. Organizational health was the strongest predictor of stress and satisfaction. Training on and implementation of evidence-based classroom interventions did not appear to significantly impact teachers’ work-related stress or satisfaction. Instead, findings point to organizational climate and teacher connectedness as potential levers for change, supporting prior work on teacher stress and satisfaction in schools. The significance of targeting organizational factors may be particularly significant in urban school districts.     

Generalization of equivalence relations from photos to objects by preschool children

Generalized equivalence classes are stimulus classes that consist of equivalent stimuli and other physically similar class‐member stimuli. The present study evaluated whether preschool children would form equivalence classes among photos of abstract objects (2D) and show equivalence generalization to the corresponding objects (3D), printed photos (2D stimuli), and to black‐and‐white drawn pictures (2D stimuli). Six typically developing children were taught arbitrary relations to establish three 3‐member equivalence classes with 2D stimuli presented on a computer screen. AB‐AC baseline relations (for half of the participants) and AB‐BC relations (for the other half) were taught using a multiple‐probe design to assess taught and tested relations. After class formation, three types of generalization probes were conducted: generalization to 3D stimuli, generalization between 2D (printed photos) and 3D stimuli, and generalization to drawn pictures (2D). All of the participants formed the equivalence classes. Two participants met the criterion for all three generalization probe types. Two participants presented mixed results across tests, and two participants did not exhibit equivalence generalization. The results demonstrated equivalence generalization from 2D to 3D stimuli in preschool children, although the variability across participants suggests that such generalization cannot be assumed a priori.     

On S

The sentential logic S extends classical logic by an implication-like connective. The logic was first presented by Chellas as the smallest system modelled by contraining the Stalnaker-Lewis semantics for counterfactual conditionals such that the conditional is effectively evaluated as in the ternary relations semantics for relevant logics. The resulting logic occupies a key position among modal and substructural logics. We prove completeness results and study conditions for proceeding from one family of logics to another.We are grateful to Peter Apostoli, Kosta Doen, and anonymous referees for their comments on an earlier version of this paper.

Test-Retest Reliability of the Spanish Version of the Diagnostic Interview Schedule for Children (DISC-IV)

The test-retest reliability of the Spanish Diagnostic Interview Schedule for Children (DISC-IV) is presented. This version was developed in Puerto Rico in consultation with an international bilingual committee, sponsored by NIMH. The sample (N = 146) consisted of children recruited from outpatient mental health clinics and a drug residential treatment facility. Two different pairs of nonclinicians administered the DISC twice to the parent and child respondents. Results indicated fair to moderate agreement for parent reports on most diagnoses. Relatively similar agreement levels were observed for last month and last year time frames. Surprisingly, the inclusion of impairment as a criterion for diagnosis did not substantially change the pattern of results for specific disorders. Parents were more reliable when reporting on diagnoses of younger (4–10) than older children. Children 11–17 years old were reliable informants on disruptive and substance abuse/dependence disorders, but unreliable for anxiety and depressive disorders. Hence, parents were more reliable when reporting about anxiety and depressive disorders whereas children were more reliable than their parents when reporting about disruptive and substance disorders.     

Prejudice toward immigrant workers among Dutch employees: integrated threat theory revisited

Integrated Threat Theory (ITT) (Stephan & Stephan, 1993 , 1996 ) describes four types of threats as mediators in the relation between antecedent factors (previous intergroup conflict, intergroup contact, status inequalities, in‐group identification, knowledge about the out‐group, and intergroup contact) and prejudice. The four mediating types of threats, which influence prejudice according to ITT are: intergroup anxiety, negative stereotyping, realistic and symbolic threats. In this study, the ITT model was tested using structural equation modeling on data collected in sample of 187 Dutch employees. Two alternative explanatory models are proposed in which, first intergroup anxiety and then negative stereotyping mediate the relation between the other ITT threats and prejudice. The data show a good fit with the model in which negative stereotypes are considered as mediator variable. The implications of these findings for ITT are discussed in the context of recent theoretical developments in the study of stereotypes and prejudice. Copyright © 2006 John Wiley & Sons, Ltd.     

Perception of parental socialization strategies in adoptive and non-adoptive families

Although parental socialization styles have been investigated in recent years, little research has been carried out on the issue of parental styles in adoptive families. The aim of this research is to analyse parental styles both from the point of view of the parents and of adopted and non-adopted adolescents, taking as covariables the adolescents' sex and age. The sample was made up of 55 adopted adolescents (20 boys and 35 girls with an age range of 11-17 years) and their 55 adoptive parents, and 402 non-adopted adolescents (200 boys and 202 girls with an age range of 11-17 years), and their 258 parents. Two scales evaluated parental styles: the Affect Scale and the Rules and Demands Scale. The results showed that, both from the point of view of the parents and of the adolescents, adoptive families are more affective, communicative and inductive, and less critical and indulgent than non-adoptive families. No differences were found between adopted and non-adopted adolescents on the Parents' Rigidity Scale.     

Structural validity of miokinetic psychodiagnosis-revised and digitalyzed (MKP-RD) lineograms

In this study, we have applied a principal components analysis to the data obtained from a graphical record of motor behaviour performed without vision. The data was obtained from two samples, one made up of men and the other one made up of women. Hand dominance was controlled in both samples. Five independent factors were obtained: Factor I (Tendency to increase or decrease the length), Factor II (Tendency to deviate in a sagittal direction), Factor V (Tendency to deviate in a frontal direction); two factors (III and IV) were found in a transversal direction. This factor structure did not depend on sex, because the same structure was found in both sexes, nor it could be explained by learning, because the same factors appeared for each hand, except for Factors III and IV which were different for each hand. This study supports different motor dispositions as foundations of behaviour tendencies.
