The Intelligence Quotient (IQ) tests and the corresponding psychometric explanations dominate both the scientific and popular views about human intelligence. Though the IQ tests have been in currency for long, there exists a gap in what they are believed to measure and what they do. While the IQ tests index the quality of cognitive functioning in selected domains of mental repertoire, the applied settings often inflate their predictive value leading to an interpretive gap. The present article contends that studying (...) the influence of motivational and affective processes on cognitive functioning would help to evolve a more psychologically comprehensive account of the IQ tests and bridge the interpretive gap. To conclude, the article suggests possible future research directions that could strengthen the predictive value of the IQ tests. (shrink)

The idea that intelligence is embedded not only in a single brain network, but instead in a complex, well-optimized system of complementary networks, has led to the development of whole brain network analysis. Using graph theory to analyze resting-state functional MRI data, we investigated the brain graph networks (or brain networks) of high intelligence quotient (HIQ) children. To this end, we computed the “hub disruption index κ”, an index sensitive to graph network modifications. We found significant topological differences in (...) the integration and segregation properties of brain networks in HIQ compared to standard IQ children, not only for the whole brain graph, but also for each hemispheric graph, and for the homotopic connectivity. Moreover, two profiles of HIQ children, homogenous and heterogeneous, based on the differences between the two main IQ subscales (verbal comprehension index (VCI) and perceptual reasoning index (PRI)), were compared. Brain networks changes were more pronounced in the heterogeneous HIQ than in the homogeneous HIQ subgroups. Finally, we found significant correlations between the graph networks’ changes and the full-scale IQ (FSIQ), as well as the subscales VCI and PRI. Specifically, the higher the FSIQ the greater was the brain organization modification in the whole brain, the left hemisphere, and the homotopic connectivity. These results shed new light on the relation between functional connectivity topology and high intelligence, as well as on different intelligence profiles. (shrink)

This study investigated the effect of Mahjong, which is a table game played by three or four players and involves intellectual activity, on the intelligence quotient of children. The participants were children between the age of 6 and 15 years, and their IQ was assessed immediately after enrolling in children's Mahjong classes and 1 year after the enrollment using the Wechsler Intelligence Scale for Children Fourth Edition. Twenty children were included in the analysis. Their mean age at the time (...) of the initial evaluation was 9 years and 6 months. In addition, we conducted a 1-year post-examination. The change in the IQ of this group was compared to that of a historical control group with a similar age range and test–retest interval. The mean overall full-scale IQ of the 20 children during the initial and post-1-year examinations was 106.05 and 113.75, respectively, and showed a statistically significant increase. Based on the subscale index, the verbal comprehension index and processing speed index scores both showed a statistically significant increase from 100.6 to 106.75 and from 108.05 to 119.05, respectively. The PSI of the children included in the analysis showed a statistically significant increase compared to the historical control group. This study suggests that children who participate in Mahjong classes during their childhood have increased PSI scores of WISC-IV. (shrink)

Intelligence, genius and mental ability were a cluster of traits that received much attention in eugenics discourse. Intelligence was regarded as one of the good qualities superior men possessed, in turn beneficial for society as a whole. On the other hand, the socially problematic or unproductive were identified as being of inferior mental quality: “feeble-minded”. By and large, eugenicists thought that (1) intelligence was a unitary psychological trait that could be measured, being quantified as an intelligence quotient (IQ); (2) (...) intelligence was paired with educational achievement, reputation, and economic success; (3) a certain degree of intelligence was necessary to act morally and to foresee the consequences of one’s actions. Despite the prominent role of intelligence in the history of eugenics, there is considerable lack of clarity in what this general mental ability was considered to be. (shrink)

Publication date: 15 October 2018 Source: Author: Donovan A. McFarlane This paper examines the constructs “Level of Educational Attainment” and “Intelligence Quotient” using a Case Study Approach based in current United States political conflicts and debates between U.S. Representative Maxine Waters and U.S. President Donald Trump. Specifically, the researcher examines U.S. President Donald Trump’s claim that U.S. Representative Maxine Waters, a democratic member of the U.S. Congress from the State of California, is a “low IQ individual”. The researcher examines (...) IQ indicators and focuses on the Level of Educational Attainment of Trump and Waters by accessing, analyzing, and interpreting the most current vital data on Level of Educational Attainment at the post-secondary level, specifically examining both parties’ LEA in relation to the population samples within their age groups. Additionally, the researcher briefly looks at the life circumstances of both Donald Trump and Maxine Waters to make an educated conclusion about both leaders’ levels of intelligence and IQs.

In recent years, the genetic testing and selection of IVF embryos, known as preimplantation genetic testing (PGT), has gained much traction in clinical assisted reproduction for preventing transmission of genetic defects. However, a more recent ethically and morally controversial development in PGT is its possible use in selecting IVF embryos for optimal intelligence quotient (IQ) and other non–disease-related socially desirable traits, such as tallness, fair complexion, athletic ability, and eye and hair colour, based on polygenic risk scores (PRS), in (...) what is referred to as PGT-P. Artificial intelligence (AI) and machine learning–based analysis of big data sets collated from genome sequencing of specific human ethnic populations can be used to estimate an individual embryo’s likelihood of developing such multifactorial traits by analysing the combination of specific genetic variants within its genome. Superficially, this technique appears compliant with Islamic principles and ethics. Because there is no modification of the human genome, there is no tampering with Allah’s creation (_taghyīr khalq Allah_). Nevertheless, a more critical analysis based on the five maxims of Islamic jurisprudence (_qawa'id fiqhiyyah_) that are often utilized in discourses on Islamic bioethics, namely _qaṣd_ (intention), _yaqın̄_ (certainty), _ḍarar_ (injury), _ḍarūra_ (necessity), and _`urf_ (custom), would instead reveal some major ethical and moral flaws of this new medical technology in the selection of non–disease-related socially desirable traits, and its non-compliance with the spirit and essence of Islamic law (shariah). Muslim scholars, jurists, doctors, and biomedical scientists should debate this further and issue a fatwa on this new medical technology platform. (shrink)

The primary aim of this study was to determine the role of psychometric intelligence, emotional intelligence, and emo-sensory intelligence in university students’ academic achievement. To this end, 212 university students at different academic levels, composed of 154 females and 58 males, were asked to complete the Raven’s Progressive Matrices, the Bar-On Emotional Quotient Inventory, and the Emo-Sensory Intelligence Scale. Data were then matched with students’ Grade Point Averages as a measure of their academic achievement. The results revealed that students’ (...) level of IQ and EQ could positively predict their academic achievement. In the case of their ESQ level, its auditory sub-component was found to be a positive predictor of academic success. Results were discussed, and possible implications and applications for increasing students’ chances for success were presented. (shrink)

While major religions espouse moral values encouraging prosocial behavior, the empirical evidence supporting the effectiveness of religious influence on such behavior, as proposed by the religious pro-sociality hypothesis, remains inconclusive. To explore this further, we conducted two studies to test this hypothesis in Pakistan, a Muslim-majority Asian nation, focusing on whistleblowing as a prosocial behavior. The first study gathered cross-sectional data from 323 undergraduate business students in Karachi, Pakistan, utilizing hypothetical scenarios of academic cheating and bank embezzlement. Participants completed a (...) scenario-based questionnaire assessing intrinsic religiosity, personality traits, and whistleblowing intentions. Measures were adapted for the Muslim context, with intrinsic religiosity assessed using the Age Universal Intrinsic-Extrinsic (AUIE) scale and personality traits measured using the Ten-Item Personality Inventory (TIPI) scale. Regression analysis of these data revealed that while intrinsic religiosity significantly predicted whistleblowing intentions in the academic cheating scenario, it did not do so in the bank embezzlement scenario. Furthermore, multiple regression modeling to test moderating effects of personality traits did not yield significant results for either scenario. The second study employed an experimental design to observe actual whistleblowing behavior among 85 undergraduate business students in Karachi, Pakistan. Participants were randomly assigned to either a religious or a neutral condition, aiming to assess the impact of intrinsic religiosity on whistleblowing behavior. The experiment used a cover story which involved a confederate cheating during an intelligence quotient (IQ) test. The purpose of this design was to examine whether the participant, acting as the sole witness to wrongdoing, would intervene and blow the whistle. Data analysis using logistic regression indicated that intrinsic religiosity did not significantly predict whistleblowing behavior across both the experimental and control conditions. These contrasting results highlight the complexity of whistleblowing, emphasizing its subjective nature and the influence of social dynamics on behavior. (shrink)

ENG: We all have our own ideas about what it is like to be intelligent. Indeed, even the experts disagree on this topic. This has generated diverse theories on the nature of intelligence and its genetic and environmental bases. Many scientific and philosophical questions thus remain unaddressed: is it possible to characterize intelligence in scientific terms? What do IQ tests measure? How is intelligence influenced by genetics, epigenetics, and the environment? What are the ethical and social implications of the (...) research on this topic? This book aims to provide the readers with the conceptual resources to critically analyze scientific findings and orientate themselves in this multi-faceted debate across biology, psychology, neuroscience, philosophy, and anthropology. -/- ITA: Ognuno di noi ha una propria idea di cosa significhi essere intelligenti, tanto che anche gli scienziati esperti in materia hanno opinioni differenti al riguardo. Ciò ha contribuito a generare teorie contrastanti sulla natura dell’intelligenza e su quali siano le sue basi genetiche e ambientali. Non è un caso, dunque, che diverse domande scientifiche e filosofiche restino ancora aperte: è possibile caratterizzare scientificamente l’intelligenza? Cosa misurano i test del QI? In che modo genetica, epigenetica e ambiente influenzano l’intelligenza? Quali sono le implicazioni etiche e sociali della ricerca sull’argomento? Oltre ad analizzare questi problemi, il testo intende fornire gli strumenti concettuali necessari per leggere criticamente i dati scientifici e orientarsi in uno sfaccettato e affascinante dibattito a cavallo tra biologia, psicologia, neuroscienze, filosofia e antropologia.

Musical prodigies reach exceptionally high levels of achievement before adolescence. Despite longstanding interest and fascination in musical prodigies, little is known about their psychological profile. Here we assess to what extent practice, intelligence, and personality make musical prodigies a distinct category of musician. Nineteen former or current musical prodigies were compared to 35 musicians with either an early or late start but similar amount of musical training, and 16 non-musicians. All completed a Wechsler IQ test, the Big Five Inventory, the (...) Autism Spectrum Quotient, the Barcelona Music Reward Questionnaire, the Dispositional Flow Scale, and a detailed history of their lifetime music practice. None of the psychological traits distinguished musical prodigies from control musicians or non-musicians except their propensity to report flow during practice. The other aspects that differentiated musical prodigies from their peers were the intensity of their practice before adolescence, and the source of their motivation when they began to play. Thus practice, by itself, does not make a prodigy. The results are compatible with multifactorial models of expertise, with prodigies lying at the high end of the continuum. In summary, prodigies are expected to present brain predispositions facilitating their success in learning an instrument, which could be amplified by their early and intense practice happening at a moment when brain plasticity is heightened.
