Déjà vu All Over Again: A Unitary Biological Mechanism for Intelligence Is (Probably) Untenable

- Nearly a century ago, Spearman proposed that “specific factors can be regarded as the ‘nuts and bolts’ of cognitive performance…, while the general factor is the mental energy available to power the specific engines”. Geary (2018; 2019) takes Spearman’s analogy of “mental energy” quite literally and doubles-down on the notion by proposing that a unitary energy source, the mitochondria, explains variations in both cognitive function and health-related outcomes. This idea is reminiscent of many earlier attempts to describe a low-level biological determinant of general intelligence. While Geary does an admirable job developing an innovative theory with specific and testable predictions, this new theory suffers many of the shortcomings of previous attempts at similar goals. We argue that Geary’s theory is generally implausible, and does not map well onto known psychological and genetic properties of intelligence or its relationship to health and fitness. While Geary’s theory serves as an elegant model of “what could be”, it is less successful as a description of “what is”.

Sharing Perceptual Experiences through Language
- 2023

Ingår i: Journal of Intelligence. - 2079-3200. ; 11:7

Tidskriftsartikel (refereegranskat)abstract
- The aim of this article is to shed light on how sensory perceptions are communicated through authentic language. What are the language resources available to match multimodal perceptions, and how do we use them in real communication? We discuss insights from previous work on the topic of the interaction of perception, cognition, and language and explain how language users recontextualise perception in communication about sensory experiences. Within the framework of cognitive semantics, we show that the complexities of multimodal perception are clearly reflected in the multifunctional use of words to convey meanings and feelings. To showcase the language resources employed, we base our findings on research on how architects convey their perceptions of built space. Two main patterns emerge: they use multimodal expressions ( soft, bland, and jarring) and descriptions of built space through motion ( the building reaches out, or routes and directions such as destination, promenade, route, or landscape in combination with verbs such as start and lead) in which case the architect may either be the observer or the emerged actor. The important take-home message is that there is no neat and clear a priori link between words and meanings, but rather "unforeseen" patterns surface in natural production data describing sensory perceptions.

Low-Performing Students Confidently Overpredict Their Grade Performance throughout the Semester
- 2023

Ingår i: Journal of Intelligence. - : MDPI AG. - 2079-3200. ; 11:10

Tidskriftsartikel (refereegranskat)abstract
- When asked to predict how they will perform on an upcoming exam, students are often poorly calibrated, typically in the direction of overpredicting their performance. Research shows that low-performing students’ calibration tends to remain poor across multiple tests over the course of a semester. We tested whether these students remain confident in these erroneously high grade predictions across the semester or whether their confidence wanes, suggesting some degree of metacognitive awareness. In two studies, students made grade predictions prior to taking four in-class exams and then rated their level of confidence in their predictions. Results from both studies showed that miscalibration and confidence remained stable across tests, suggesting that low-performing students continued to believe that they would perform well on upcoming exams despite prior evidence to the contrary.

An Investigation of the Relationship between Personality, Cognitive Ability, and Work Engagement in Intellectually Gifted Individuals
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Do personality traits in highly intelligent individuals relate to their work engagement? Seemingly little is known about the relationship between personality and work engagement for gifted individuals. In what may be the first study to do so, a Swedish Mensa sample (n = 353) was explored with a two-part aim: to assess psychometric personality properties and to investigate the relationship between personality traits (Mini-IPIP6) and work engagement (UWES-9). The results of the Mensa members and the Mturk sample (1.4 SD lower in cognitive ability based on ICAR-16) were compared using a confirmatory factor analysis (CFA) and a regression. The findings indicated that the Mensa sample had higher openness (d =.50) and honesty-humility (d =.65) and that personality traits were similarly related to work engagement in both groups, with the exception that neither openness nor honesty-humility were related to work engagement in the Mensa sample. The characteristics of intellectually gifted individuals are further discussed.

It Runs in the Family: Testing for Longitudinal Family Flynn Effects
- 2023
-
Ingår i: JOURNAL OF INTELLIGENCE. - : MDPI. - 2079-3200. ; 11:3
-
Tidskriftsartikel (refereegranskat)abstract
- The Flynn effect refers to increases over time in measured (particularly fluid) intelligence of approximately 3 IQ points per decade. We define the Flynn effect at the family level, using longitudinal data and two new family-level cohort definitions. Multilevel growth curve analyses of the National Longitudinal Survey of Youth 1979 data showed that children in families with later-born mothers had higher average PIAT math scores, and lower average reading comprehension scores and growth, in young and middle childhood. Children in families where the first child was born later had higher average PIAT math, reading recognition, and reading comprehension scores, as well as larger developmental growth. The latter family-level Flynn effects were of higher magnitudes than the usual individual-level Flynn effect found in previous studies. Our results, showing family level-intercept and slope Flynn effects for both maternal birthyear and first child birthyear, have implications for research aiming to explain the Flynn effect.
