Verbal Abilities in Low and Highly Proficient Bilinguals

The study investigated native language verbal skills among low and highly proficient bilinguals, using the WISC III verbal subtests. Highly proficient bilinguals showed a superiority for almost all verbal subtests. This finding lends support to Threshold Theory which maintains that bilinguals need to achieve high levels of linguistic proficiency before bilingualism can promote cognitive development. Our study also shows that verbal ability underlying proficiency in the native language can be generalized to a foreign language, revealing a causal connection between native and foreign language learning.     

High and Low Reading Comprehension Achievers' Strategic Behaviors and Their Relation to Performance in a Reading Comprehension Situation

This study aimed at investigating the actual strategic behaviors of high and low achievers in reading comprehension and their relation with respective performance. The participants were 45 individually examined third graders, 20 high and 25 low reading comprehension achievers. Cognitive, metacognitive, and motivational aspects of the participants' strategic behaviors during text comprehension was directly recorded by two observers by means of a structured observation form. The results revealed a relatively different profile of strategic behaviors between high and low achievers. Students' strategic behaviors during dealing with text comprehension were strongly related to respective performance for both groups.     

Temptation and Deliberation

There is a great deal of plausibility to the standard view that if one is rational and it is clear at the time of action that a certain move, say M₁, would serve one’s concerns better than any other available move, then one will, as a rational agent, opt for move M₁. Still, this view concerning rationality has been challenged at least in part because it seems to conflict with our considered judgments about what it is rational to do in cases of temptation that share the structure of Warren Quinn’s self-torturer case. I argue that there is a way to accomodate our considered judgments about the relevant cases of temptation without giving up the standard view or dismissing, as in some way rationally defective, the concerns of the agents in the relevant cases. My reasoning relies on the idea that, at least in some cases, whether an action serves one’s concerns well depends on what action(s) or course(s) of action it is part of. In the final section of the paper, I explain how this idea sheds light on an important source of frustration in collective decision-making.     

TAKING ON INTENTIONS

I propose a model of intention formation and argue that it illuminates and does justice to the complex and interesting relationships between intentions on the one hand and practical deliberation, evaluative judgements, desires, beliefs, and conduct on the other. As I explain, my model allows that intentions normally stem from pro-attitudes and normally control conduct, but it is also revealing with respect to cases in which intentions do not stem from pro-attitudes or do not control conduct. Moreover, it makes the connection between forming an intention and altering one's deliberative framework transparent, and directly accounts for the fact that while intentions can affect how it makes sense for an agent to reason and what it makes sense for her to do, one cannot make an action that one is tempted to perform worth performing simply by forming a related intention.     

Cognitive status in Down syndrome individuals with sleep disordered breathing deficits (SDB)

Twelve subjects with Down syndrome underwent polysomnographic studies during night sleep and performed the Mini-Mental state test and the Raven Progressive Matrices (RPM), sets A, B, and B(1). Sleep-disordered breathing (SDB) deficits were observed in Down syndrome individuals and their Mini-Mental and RPM scores were extremely low. Regression analysis of the results revealed that the number of apneas per hour was related with the results of the RPM, set A, which were also related with the orientation of Mini-Mental test, indicating that the more apneas an individual has the more difficulties he has in the kind of visuoperceptual skills, including orientation, associated with normal right hemisphere functioning, which are tested by set A of the RPM.     

Left-handedness and inheritance of bronchial asthma

A statistically significant difference in mean laterality quotients of 15 asthmatic and 106 nonasthmatic children showed a coexistence of left-handedness and asthma early in life. It is suggested that this phenomenon is not only a fetal event as the Geschwind-Galaburda hypothesis claims but it is mainly based on maternal line inheritance.     

Visual field asymmetries for rhyme and semantic tasks in fluent and nonfluent bilinguals.

A tachistoscopic study investigated hemispheric specialization among fluent and nonfluent bilinguals for rhyme and semantic tasks in both their languages. Fluent bilinguals gave faster responses and made fewer errors in their responses to the words presented in the RVF(LH) while the opposite happened for nonfluent, which indicates greater RH participation in the first stages of a second language. Fluent bilinguals performed better not only in the second but also in their native language, suggesting superior language skills on the part of fluent bilinguals. A LVF(RH) superiority was obtained for semantic tasks, indicating RH participation in semantic judgments. Another finding was a high ratio of first-born children among fluent bilinguals, potentially explained in terms of parental attitudes toward first- versus later born children.     

Conceptual Competence as a Component of Second Language Fluency

In this article we argue that conceptual competence should be seen as a component of second language (L2) communicative competence. Abstract concepts are highly expressed by means of metaphors, metonymies, idioms and other types of figurative language. In literature it is suggested that knowledge and appropriate use of these lexical segments are closely related to L2 mastery and therefore conceptual instruction is expected to facilitate L2 learning. To test the relationship between conceptual and L2 competence we conducted an experiment in which Modern Greek learners were encouraged to express their views on the concept of happiness. The results showed their weak performance in conveying their ideas in a coherent and acceptable manner.
