A Study of the Relationships Between Hemispheric Asymmetries and Intellectual Abilities

McShane, Anne 01 May 1987 (has links)
This study investigated the functional significance of cerebral asymmetries. Width measurements of the human brain were derived from computerized tomographic (CT) films and related to intellectual variables as determined by the Wechsler Adult Intelligence Scale Revised (WAIS-R). Subjects were adults of both sexes who had been referred for neurologic examination and were diagnosed as having no abnormalities (N=28). Reasons for referral included headache, dizziness, or to rule out central nervous system damage following various types of trauma. The asymmetry of hemispheric widths (left minus right) in the frontal, temporoparietal, and occipital areas was correlated with Verbal IQ minus Performance IQ scores within subjects. The difference between verbal and performance IQ scores was used because it reflected an IQ imbalance (IQ-I). Correlations obtained were -.30, -.26, and .06 (respectively). None of these correlations were significant by means of a two-tailed test. There were relationships between particular width asymmetries and individual subtest scores (p≤.05). The Verbal 1 (V1) subtest (Information) was correlated -.50, -.39 and -.47 with brain width asymmetries at 25%, 33% and 50% of the AP distance respectively. V1 correlated .39 with width asymmetry at 80%. Verbal 3 (Vocabulary), verbal 4 (Arithmetic) and verbal 5 (Comprehension) correlated .53 .38, and .39 with width asymmetry at 60% of the AP distance. Performance 1 (Picture Completion) correlated .46 with the width asymmetry at 20% of the AP length. In summary, there does appear to be some specific correlation between individual variation in brain asymmetry and cognitive processing. Relative size of the area of the brain that is involved in a key aspect of a particular cognitive processing may be a factor in the effectiveness of that processing. Further research appears warranted to confirm and clarify a possible relation between anatomical asymmetry and patterns of intellectual ability.

INTELLIGENCE AND THE STRUCTURES OF THE LINGUAL GYRI

Emil, Norrman January 2023 (has links)
Finding neural correlates of intelligence and cognitive abilities in the developing brain during childhood may be important in many ways, such as predicting and understanding educational abilities or making clinical evaluations of patients. Even if substantial contemporary research has established relationships between brain structures and general intelligence, little is known about the lingual gyri and their links to IQ. In this thesis it is examined (1) whether cortical thickness in the right and left lingual gyri is associated with different levels of IQ in childrenand (2) if the rate of change in cortical thickness located in the lingual gyri is associated with change in Performance IQ (PIQ). Neuroimaging data originated from a study by Solé-Casals and colleagues (2019) as well as a dataset from a study by Suárez-Pellicioni and colleagues(2019). Both datasets were downloaded from the OpenNeuro library of brain imaging data. Neuroimaging metrics of twenty-nine boys of approximately twelve years of age were utilizedto test the hypothesis that higher IQ is related to thinner cortical thickness in lingual gyri. Neuroimaging metrics of twenty-one girls and fifteen boys under fourteen years of age utilized to examine if the rate of change in cortical thickness is related to a change in Performance IQ.Results revealed that high IQ was related to thinner cortical thickness at the age of twelve. Further results indicated that rate of thinning of the cortex in the lingual gyri is correlated to change in Performance IQ. The present thesis adds to the growing evidence that regional cortical thickness and change of cortical thickness are relevant biomarkers for intelligence. Future research with larger sample sizes and longitudinal design with additional points in timemight be needed to confirm the results of the present thesis.

Ledarintelligens, självkänsla och personlighetsdrag före och efter deltagande i UGL / Leadership intelligence, self-esteem and personality traits before and after participation in UGL

Ekegren, Maria January 2012 (has links)
Sedan 1981 har ledarutbildningen UGL (Utveckling av Grupp och Ledare) varit en grundkurs för blivande officerare och är idag ett mycket använt koncept även inom näringsliv och offentlig förvaltning. Kursens mål är i enlighet med inbjudan bl.a. att få ökad förmåga att arbeta med reflektion, förstå känslors inverkan, kunna ta och ge utvecklande feedback, förstå hur värderingar påverkar ledarskap samt förstå behovet av olika ledarstilar. Syftet med föreliggande studie var att undersöka om det förelåg skillnad i följande variabler: ledarintelligens (emotionell, rationell och själslig intelligens), självkänsla (bas-, förvärvad och prestationsinriktad) och personlighetsdrag före resp. efter deltagande i UGL. Ledarintelligens är en ny ledarskapsmodell (Ronthy, 2006) och ett frågeformulär som bygger på denna teori är under utveckling. Ett annat syfte med studien var därför att undersöka begreppsvaliditeten hos detta instrument. Studien omfattade 125 ledare (M = 38,5 år, SD = 7,8), varav 82 kvinnor. Samtliga genomgick ledarutvecklings­programmet UGL under 2011. Tre självskattningsformulär användes i studien.  Före och direkt efter utbildningen undersöktes samtliga variabler, efter sex månader endast ledarintelligens. Resultatet visade signifikant skillnad före resp. direkt efter utbildning gällande emotionell intelligens, rationell intelligens, själslig intelligens, bassjälvkänsla, bitterhet, psykisk ångestbenägenhet, stresskänslighet samt social konformitet. De självskattade ökningarna i ledarintelligens kvarstod i nivå efter sex månader. Resultat från korrelationsprövningar indikerade teoretiskt rimliga samband. Då den självskattade nivån av den emotionella, den rationella samt den själsliga intelligensen uppmätte högre resultat efter deltagande i UGL i föreliggande studie, verkar det som att denna kompetensutvecklingsinsats möjligen kan ha bidragit positivt till ökad ledarintelligens hos deltagarna. / Since 1981 the leadership training UGL (Understanding Group and Leader) has been used as a basic course for new officers, and it´s today a frequently applied concept even in the commercial sector and public administration. The objectives of the course is, in accordance with the invitation to improve the participants’ abilities working with reflections, understanding the influence of emotions, providing developing feedback, understanding how our values influence leadership as well as understanding the needs of different leadership styles. The aim of the present study was to evaluate if there was a difference in the following variables: leadership intelligence (emotional, rational and spiritual intelligence), self-esteem (basic, earning and performance-based) and personality traits, before and after participating in UGL. The leadership intelligence is a new leadership model (Ronthy, 2006), and a questionnaire based on this theory is in progress. An additional aim of this study was to investigate the construct validity of this instrument. The study included 125 participants (M = 38,5 years, SD = 7,8), whereof 82 women. Everyone participated in the leadership development program UGL in 2011. Three self-assessment forms were used in the study. Before and immediately after the leadership training all variables were evaluated, after six months only leadership intelligence was evaluated. The results showed significant differences before and after participation in emotional intelligence, rational intelligence, spiritual intelligence, basic self-esteem, embitterment, psychic trait anxiety, stress susceptibility and social desirability. The self-estimated increases in leadership intelligence were still at similar levels after six months. Results from correlation tests indicated theoretical plausible correlations. In the present study the self-rated emotional, the logical, as well as the spiritual intelligence measured higher after participation in UGL. This professional development program may have contributed in a positive direction to increase employees’ leadership intelligence.

Validity in psychological measurement:an investigation of test norms

Roivainen, E. (Eka) 20 October 2015 (has links)
Abstract A psychological test may be defined as an objective and standardized measure of a sample of behaviour. The interpretation of test results is usually based on comparing an individual’s performance to norms based on a representative sample of the population. The present study examined the norms of popular adult tests. The validity of the Wartegg drawing test (WZT) was studied using two rating scales, the Toronto Alexithymia Scale and the Beck Depression Inventory as criterion tests. Weak to moderate correlations were found. It is concluded that the WZT has some validity in the assessment of Alexithymia. Efforts to develop a psychometrically valid and reliable method of interpreting the WZT should be continued. Cross-national and historical analyses of the norms of Wechsler’s adult intelligence scale (WAIS) were performed. The results show that the Finnish WAIS III test norms are distorted in the younger age groups. Significant cross-national and cross-generational differences in relative subtest scores, test profiles were also observed. Differences in general intelligence cannot explain such variations, and educational and cultural factors probably underlie the observed differences. It is suggested that the concept of a national IQ profile is useful for cross-national test validation studies. The validity of a validity scale, the Chapman Infrequency Scale, was studied in the context of a survey study. Results showed that careless responding is significantly more frequent among psychiatric patients relative to healthy respondents. The common procedure of excluding careless responders from final samples may affect the results of survey studies targeting individuals with psychiatric symptoms. Cut-off scores for exclusion should be flexible and chosen according to the demographic and health characteristics of the sample. In conclusion, the results of this study underscore the need for up-to-date and representative test norms for valid test interpretation. / Tiivistelmä Psykologiset testit voidaan ymmärtää otoksiksi tutkittavan käyttäytymisestä. Mittauksen tulosta tulkitaan yleensä vertaamalla sitä tavalliseen tai keskimääräiseen tulokseen eli testinormeihin. Väitöskirjatutkimus tarkastelee suosittujen aikuistestien normien pätevyyttä. Warteggin piirrostestin validiteettia aleksitymian ja depression mittarina tutkittiin käyttämällä vertailukriteerinä kahta lomaketestiä, Toronton aleksitymia-asteikkoa ja Beckin depressioasteikkoa. Mitatut korrelaatiot olivat melko matalia. Tutkimuksen johtopäätöksenä oli, että Wartegg-testi saattaa olla hyödyllinen menetelmä aleksitymian toteamisessa ja että empiiriseen tutkimukseen perustuvaa tulkintamenetelmien kehittämistä pitäisi jatkaa. Tutkimuksessa selvitettiin myös Wechslerin aikuisten älykkyystestien (WAIS) eri versioiden osatestien kansallisten normien välisiä eroja ja eroja ikäkohorttien välillä. Tulokset osoittivat, että suomalaiset WAIS III testinormit ovat vinoutuneet nuorempien ikäryhmien osalta. Tutkimuksessa havaittiin merkitseviä eroja osatestien keskiarvojen suhteissa eli testiprofiileissa eri maiden ja ikäkohorttien välillä. Kyseisiä eroja ei voida selittää älykkyyden yleisellä faktorilla, vaan niiden taustalla on luultavasti koulutukseen ja kulttuuriin liittyviä tekijöitä. Osa eroista kansallisissa testiprofiileissa näyttää olevan luonteeltaan pysyviä, ja tätä tietoa voidaan käyttää hyväksi testinormien pätevyyttä arvioitaessa. Chapmanin vastaustapa-asteikon (CIS) validiteettia tutkittiin Pohjois-Suomen vuoden 1966 syntymäkohortin kyselytutkimusaineistolla. Psykiatrisista oireista kärsivät henkilöt saivat korkeampia pistemääriä kuin terveet vastaajat. Johtopäätöksenä oli, että vastaustapamittarit voivat karsia psykiatrisia potilaita liian herkästi ulos tutkimusjoukosta, mikä voi vääristää tutkimusten tuloksia. Kriteeripistemäärän pitäisi olla joustava ja sen määrityksessä pitäisi ottaa huomioon tutkimusjoukon ominaisuudet. Tutkimukset osoittavat, että testituloksen luotettava tulkinta vaatii ajanmukaiset ja edustavaan otokseen perustuvat testinormit.
