A collective intelligence factor (CI) was introduced by prior research to characterise the cognitive ability of groups. Surprisingly, individual intelligence did not predict CI. Instead, it correlated with individual social sensitivity, the equality of conversational turn-taking, and the proportion of females in a group. However, these findings…

Individuals encounter problems daily wherein varying numbers of constraints require delimitation of memory to target goal-satisfying information. Multiply-constrained problems, such as the compound remote associates, are commonly used to study this type of problem solving. Since their development, multiply-constrained problems have been…

In this study the cognitive correlates of reading comprehension in English as a foreign language were studied. The Cattell-Horn-Carroll model of cognitive abilities was used as the theoretical grounding for the study. We examined the relationship between fluid intelligence, crystallized intelligence, verbal analogical reasoning, and speed of…

The authors examined whether individual differences in fluid intelligence (gF) modulate the testing effect. Participants studied Swahili--English word pairs and repeatedly studied half the pairs or attempted retrieval, with feedback, for the remaining half. Word pairs were easy or difficult to learn. Overall, participants showed a benefit of…

Recent theories of autism have emphasised the cognitive strengths and weaknesses in those with autism, which are also seen to some degree in non-clinical samples with higher autistic-like traits. The dual process theory of autism proposes that people with autism and non-clinical people with a higher degree of autistic-like traits have a propensity…

This study investigated direct and indirect effects of executive functions on reading comprehension in adolescents (N = 87, M = 14.0 years, SD = 1.5) by testing for parallel mediation of effects of working memory, task-switching, and inhibitory control via decoding and text recall/inference. Working memory showed direct and indirect effects on…

Four experiments tested the conventional wisdom in experimental psychology that participants who complete laboratory tasks systematically differ in their cognitive abilities, motivational levels, and personality characteristics as a function of the time at which they participate during an academic term. Across 4 experiments with over 2,900…

The general purpose of the current study was to clarify the role and estimate the correlation of specific cognitive abilities with Second Language (L2) reading achievement of English Foreign Language (EFL) university students. Since there are not ample available studies about the cognitive correlates of reading comprehension in a second language,…

The testing effect, defined as the positive effect of "retrieval practice" (i.e., self-testing) on long-term memory retention relative to other ways to support learning, is a robust empirical phenomenon. Despite substantial scientific evidence for the testing effect, less is known about its effectiveness in relation to individual…

In this project we test the utility of an adaptive e-learning study tool (LearnSmart) within the context of a large undergraduate psychology course. We measured student usage of the e-learning tool and the effect that this usage has on academic outcomes, while controlling for the effects of intellectual ability and personality traits such as…

Although memory retrieval often enhances subsequent memory, Peterson and Mulligan (2013) reported conditions under which retrieval produces poorer subsequent recall--the negative testing effect. The item-specific--relational account proposes that the effect occurs when retrieval disrupts interitem organizational processing relative to the restudy…

The research set out in this paper attempts to identify whether one of three conventional IQ tests is more capable of identifying intellectual potential amongst poor children in Dar es Salaam. To this end 1857 children from 17 government schools in poor districts of Dar es Salaam were asked to complete a questionnaire and undertake a range of…

Lexical access is a core component of word processing. In order to produce or comprehend a word, language users must access word forms in their mental lexicon. However, despite its involvement in both tasks, previous research has often studied lexical access in either production or comprehension alone. Therefore, it is unknown to which extent…

The purpose of the study was to reveal the cognitive characteristics of talented children who come from economically vulnerable contexts in Chile. Raven's Standard Progressive Matrices (SPM) was administered to a sample of 5,160 students who took part in the process of identification of gifted students from the program PENTA UC in Chile between…

The relationships between processing speed, intelligence, and school achievement were analyzed on a sample of 184 Russian 16-year-old students. Two speeded tasks required the discrimination of simple geometrical shapes and the recognition of the presented meaningless figures. Raven's Advanced Progressive Matrices and the verbal subtests of…
