Intelligence Of Bearded Dragons, Sydney Herndon

Honors College Theses

The purpose of this thesis is to study and explain the intelligence of bearded dragons. Bearded dragons (Pogona spp.) are a species of reptile that have been popular in recent years as pets. Until recently, not much was known about their intelligence levels due to lack of appropriate research and studies on the species. Scientists have been studying the physical and social characteristics of bearded dragons to determine if they possess a higher intelligence than previously thought. One adaptation that makes bearded dragons unique is how they respond to heat. Bearded dragons optimize their metabolic functions through a …

Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman

Journal of Global Education and Research

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the process of solving complex problems (e.g., general intelligence), results were often found to be rather heterogeneous. As this was found to be partially caused by fundamental differences between measurements of CPS, a new operationalization was used in the present study: Following the Microworld approach, CPS was assessed in the simulation game Cities: Skylines …

Assessing General Cognitive And Adaptive Abilities In Adults With Down Syndrome: A Systematic Review, Sarah Hamburg, Bryony Lowe, Carla Marie Startin, Concepcion Padilla, Antonia Coppus, Wayne Silverman, Juan Fortea, Shahid Zaman, Elizabeth Head, Benjamin L. Handen, Ira Lott, Weihong Song, André Strydom

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Measures of general cognitive and adaptive ability in adults with Down syndrome (DS) used by previous studies vary substantially. This review summarises the different ability measures used previously, focusing on tests of intelligence quotient (IQ) and adaptive behaviour (AB), and where possible examines floor effects and differences between DS subpopulations. We aimed to use information regarding existing measures to provide recommendations for individual researchers and the DS research community.

RESULTS: Nineteen studies reporting IQ test data met inclusion for this review, with 17 different IQ tests used. Twelve of these IQ tests were used in only one study while …

The Effects Of Stress On Delay Discounting Performance For Higher And Lower Intelligence Individuals, Rebecca Brodoff

Honors Theses

Maintaining self-control can be a draining and arduous task, which may be affected by several external factors, such as stress or IQ level. An experiment was conducted on the effects of induced stress on Delay Discounting (DD) performance, or a measure of self-control, and the extent to which IQ level moderated this effect. Participants recorded their SAT or ACT scores (which were later converted to IQ scores), were exposed to a stress-inducing or control task requiring them to place their arms in ice-cold or luke-warm water, respectively, and then completed a DD task where they made a number of hypothetical …

Mental Retardation: A Mri Study Of 146 Brazilian Children, Armando F. Rocha, Cláudia C. Leite, Fábio T. Rocha

Armando F Rocha

We report results of a magnetic ressonance imaging (MRI) study of 146 Brazilian children, whose intelligence quotient scored less than 70. 50% of MRI examinations did not exhibit any signal of structural lesion (N group), whereas a focal thinning at the junction of the body and splenium of the corpus callosum; ventricular asymmetry; periventricular leukomalacia; gliosis and arachnoid cysts were among the most frequent findings in the remaining of subjects (L group). Maternal stress and altered blood pre ss u re were the most frequent findings in the pre-natal history of both N and L children. Familial antecedents of mental …

Confirmation Of The Structural Dimensionality Of The Stanford-Binet Intelligence Scale (Fourth Edition), Gregory J. Boyle

Gregory J. Boyle

The new Stanford-Binet Intelligence Scale (fourth edition) seemingly represents an important advance in design and construction over the earlier form L-M. The latest version of the instrument (SB-IV) is purported to index both crystallized intelligence (Verbal and Quantitative Reasoning Areas) and fluid intelligence (Abstract/Visual Reasoning Area) structural dimensions respectively. Given the prominence of modem information­ processing theories of cognition, a separate Short-Term Memory (STM) Area is also provided. The authors provided confirmatory factor analytic (CFA) evidence to support their claim for the construct validity of each of the four cognitive ability areas. However, several inconsistent factor loadings were apparent, for …

Norm-Of-Reaction: Definition And Misinterpretation Of Animal Research, Steve A. Platt, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

The development of a phenotype is due to an interaction of the genotype with the environment. Two terms have been used to describe the outcome of this interaction, the norm-of-reaction and the reaction range. The first represents the theoretically limitless distribution of the phenotypes that may be expressed by a given genotype. The reaction range implies an upper and lower limit for phenotype expression possible from a given genotype. A critical distinction between the reaction range and the norm-of-reaction is that the norm-of-reaction is a statement of the conceivable interactions found but does not imply any predictability other than that …
