The development of beginning decoding and encoding skills is influenced by linguistic skills as well as executive functions (EFs). These higher-level cognitive processes include working memory, inhibition, and cognitive flexibility, and individual differences in these EFs have been shown to contribute to early academic learning. The present study…

The placebo effect is any outcome that is not attributed to a specific treatment but rather to an individual's mindset (Benson & Friedman, 1996). This phenomenon can extend beyond its typical use in pharmaceutical drugs to involve aspects of everyday life, such as the effect of sleep on cognitive functioning. In 2 studies examining whether…

The primary purpose of this study was to investigate the various neurocognitive processes concomitant to reading by attempting to identify various subtypes of reading disorders in a referred sample. Participants were 216 elementary school students in grades two through five who were given select subtests of the Woodcock Johnson-III Tests of…

White matter disruption is an important determinant of cognitive impairment after brain injury, but conventional neuroimaging underestimates its extent. In contrast, diffusion tensor imaging provides a validated and sensitive way of identifying the impact of axonal injury. The relationship between cognitive impairment after traumatic brain injury…

The ability to learn visual-phonological associations is a unique predictor of word reading, and individuals with developmental dyslexia show impaired ability in learning these associations. In this study, we compared developmentally dyslexic and nondyslexic adults on their ability to form cross-modal associations (or "bindings") based…

Recent evidence suggests the existence of multiple cognitive mechanisms that support the general cognitive ability factor (g). Working memory and processing speed are the two best established candidate mechanisms. Relatively little attention has been given to the possibility that associative learning is an additional mechanism contributing to g.…

The ability to automatically and implicitly detect complex and noisy regularities in the environment is a fundamental aspect of human cognition. Despite considerable interest in implicit processes, few researchers have conceptualized implicit learning as an ability with meaningful individual differences. Instead, various researchers (e.g., Reber,…

This paper examines the characteristics of the thinking skill we call "melioration" i.e., the competence to borrow a concept from a field of knowledge supposedly far removed from his or her domain, and adapt it to a pressing challenge in an area of personal knowledge or interest. The skill has its source in conscious personal meaning-making, not…

This study tested whether the word association employed by individual students could be used to predict their performance in a particular course. It was designed to explore a new method for describing the various models used in thinking and to determine whether this approach would yield results that were consonant with current cognitive theory. At…

This study examines some relationships pertaining to socioeconomic status and cognitive ability patterns in fourth graders. Specifically, it explores the relative merits of Jensen's hierarchical theory of two levels of cognitive ability, in contrast to a process scheme, positing two parallel modes of coding information.

Clarification of one aspect of Jensen's model of cognitive abilities provided the impetus for this study. Jensen found that sentence construction as a mediator facilitated learning of paired associates, except when kindergarteners were used as subjects. The purpose of the present study is to determine whether the failure of the mediators to…

It was hypothesized that there are significant differences in intellectual patterns between black and white populations which can be demonstrated on the Wechsler Adult Intelligence Scale (WAIS). A one-way analysis of variance was performed on the subjects' scores on the WAIS subtests and the Verbal, Peformance and Full Scale IQ using the ethnic…
