"Ginkgo biloba" has been reported to affect the neurotransmitter system and to have antioxidant properties that could impact the pathogenesis of Autism Spectrum Disorder. Based on these studies, we decided to assess the effectiveness of "Ginkgo biloba" extract (Ginko T.D., Tolidaru, Iran) as an adjunctive agent to risperidone in the treatment of…

Although a considerable amount of evidence has been amassed regarding the contributions of lower-level word processes, higher-level processes, and working memory to reading comprehension, little is known about the relationships among these sources of individual differences or their relative contributions to reading comprehension performance. This…

Several studies have applied the dichotomy of deep and surface approaches to learning in a range of disciplinary contexts. Existing questionnaires have largely assumed the existence of these constructs; however, in a recent study Case and Marshall (2004) described two additional context-specific approaches to learning in engineering. The current…

Studies on homophobia among adolescents routinely depart from the assumption that this attitude will be continued into adulthood. However, little research has been conducted on how the transition toward adulthood actually affects homophobia. While earlier studies relied on cross-sectional observations, the present analysis makes use of the Belgian…

The visual recognition of letters dissociates from the recognition of numbers at both the behavioral and neural level. In this article, using fMRI, we investigate whether the visual recognition of numbers dissociates from letters, thereby establishing a double dissociation. In Experiment 1, participants viewed strings of consonants and Arabic…

This study assessed the psychometric characteristics and correlates of the Perfectionistic Self-Presentation Scale--Junior Form (PSPS-JR). The PSPS-JR was designed for use with children and adolescents, but its psychometric properties and applications among early adolescents have not been investigated. The PSPS-JR has three subscales assessing the…

Research has shown that consistently right-handed individuals have poorer memory than do inconsistently right- or left-handed individuals under baseline conditions but more reliably exhibit enhanced memory retrieval after making a series of saccadic eye movements. From this it could be that consistent versus inconsistent handedness, regardless of…

The commentary discusses phenomena highlighted in the studies of the special issue such as the hypercorrection effect, overconfidence, and the efficiency of interventions designed to increase monitoring accuracy. The discussion is based on a broader theoretical framework of self-regulation of learning that stresses the inferential character of…

Many aspects of cognition decline from middle to late adulthood, but the dimensionality and generality of this decline have rarely been examined. We analyzed 20-year longitudinal data of 6203 middle-aged to very old adults from Greater Manchester and Newcastle-upon-Tyne, UK. Participants were assessed up to eight times on 20 tasks of fluid…

The function of accurately monitoring one's own learning is to support effective control of study that enhances learning. Although this link between monitoring accuracy and learning is intuitively plausible and is assumed by general theories of self-regulated learning, it has not received a great deal of empirical scrutiny and no study to date has…

Autism is a pervasive developmental condition with complex aetiology. To aid the discovery of genetic mechanisms, researchers have turned towards identifying potential endophenotypes--subtle neurobiological or neurocognitive traits present in individuals with autism and their "unaffected" relatives. Previous research has shown that relatives of…

In the globalized and technological world in which we now live, school leaders must be prepared to engage in complex and interdependent systems. Hierarchical power and authority will not provide the leader with the capacity to challenge people and systems to adapt and change to the emerging needs of students from differing social, political, and…

Traditional rhetoric attempts to find the available means of persuasion in public assemblies, law courts and ceremonials and is grounded in cultural values and beliefs. Traditional rhetoric supports the development of social communities and posits education as a primary means of maintaining these communities. In contrast, contemporary alternatives…

Based on original doctoral research conducted with midlife women and men who completed counselling for depression, this article presents research findings of male participant perspectives and experiences in managing midlife depression and the role of counselling. Hermeneutic inquiry using conversational semistructured interviews generated multiple…

Most people have 23 pairs of chromosomes; one set from the mother and one from the father. However, nondisjunction errors during meiosis can lead to a case of trisomy, where there are three rather than two chromosomes. Although such events are not uncommon, they are usually lethal, and account for a high proportion of spontaneous abortions. There…
