Intelligence: Genetics, Genes, and Genomics.

More is known about the genetics of intelligence than about any other trait, behavioral or biological, which is selectively reviewed in this article. Two of the most interesting genetic findings are that heritability of intelligence increases throughout the life span and that the same genes affect diverse cognitive abilities. The most exciting direction for genetic research on intelligence is to harness the power of the Human Genome Project to identify some of the specific genes responsible for the heritability of intelligence. The next research direction will be functional genomics--for example, understanding the brain pathways between genes and intelligence. Deoxyribonucleic acid (DNA) will integrate life sciences research on intelligence; bottom-up molecular biological research will meet top-down psychological research in the brain.

Transcriptome Analysis of High-Temperature Stress in Developing Barley Caryopses :Early Stress Responses and Effects on Storage Compound Biosynthesis

High-temperature stress,like any abiotic stress,impairs the physiology and development of plants,including the stages of seed setting and ripening.We used the Aflymetrix 22K Barley1 GeneChip microarray to investigate the response of developing barley(Hordeum vulgare)seeds,termed caryopses,after 0.5,3,and 6 h of heat stress exposure;958 induced and 1122 repressed genes exhibited spatial and temporal expression patterns that provide a detailed insight into the caryopses'early heat stress responses.Down-regulation of genes related to storage compound biosynthesis and cell growth provides evidence for a rapid impairment of the caryopsis' development.Increased levels of sugars and amino acids were indicative for both production of compatible solutes and feedback-induced accumulation of substrates for storage compound biosynthesis.Metadata analysis identified embryo and endosperm as primary locations of heat stress responses,indicating a strong impact of short-term heat stress on central developmental functions of the caryopsis.A comparison with heat stress responses in Arabidopsis shoots and drought stress responses in barley caryopses identified both conserved and presumably heat-and caryopsis-specific stress-responsive genes.Summarized,our data provide an important basis for further investigation of gene functions in order to aid an improved heat tolerance and reduced losses of yield in barley as a model for cereal crops.     

The Second Law of Thermodynamics Is the First Law of Psychology: Evolutionary Developmental Psychology and the Theory Of Tandem, Coordinated Inheritances: Comment on Lickliter and Honeycutt (2003).

Organisms inherit a set of environmental regularities as well as genes, and these two inheritances repeatedly encounter each other across generations. This repetition drives natural selection to coordinate the interplay of stably replicated genes with stably persisting environmental regularities, so that this web of interactions produces the reliable development of a functionally organized design. Selection is the only known counterweight to the tendency of physical systems to lose rather than grow functional organization. This means that the individually unique and unpredictable factors in the web of developmental interactions are a disordering threat to normal development. Selection built anti-entropic mechanisms into organisms to orchestrate transactions with environments so that they have some chance of being organization-building and reproduction-enhancing rather than disordering.

Evolutionary Psychology and Developmental Dynamics: Comment on Lickliter and Honeycutt (2003).

Evolutionary psychology provides a cogent metatheory for psychological science. It has furnished compelling theories of major domains of human functioning, including mating, parenting, kinship, morality, cooperation, conflict, aggression, and aesthetics. It has produced hundreds of empirical discoveries missed entirely by prior psychologists. Developmental dynamics, properly conceived, can add to the theoretical foundation of evolutionary psychology. But it has not provided alternative theories capable of explaining the many detailed empirical discoveries made by evolutionary' psychologists. Nor has it generated a comparable bounty of new empirical discoveries. By critical scientific standards--theoretical cogency, predictive accuracy, interdisciplinary consistency, and empirical harvest--modern evolutionary psychology fares well compared with alternatives.

Genetic testing and psychology: New roles, new responsibilities.

Advances in genetics and genetic testing promise to catalyze a fundamental change in the practice of medicine. Psychologists have much to offer as psychotherapists, researchers, educators, and policymakers to a society heavily influenced by the genetic revolution. To make the most of new opportunities available to mental health professionals in genetics, psychologists must know basic genetic principles and learn what is new about 21st-century genetics. The core competencies for all health professionals developed by the National Coalition for Health Professional Education in Genetics are related in this article to the significant roles psychologists can play in helping individuals with genetic concerns to cope with vulnerability, optimize family interaction, and improve health behaviors.

Fictions and Facts About Evolutionary Approaches to Human Behavior: Comment on Lickliter and Honeycutt (2003).

Six misconceptions about evolutionary approaches to human behavior are exposed. Evidence is adduced to support the assertions that evolutionary approaches do not (a) adopt a reductionistic "gene-centered" level of analysis, (b) assume that natural selection is the only process that creates and designs ontogenetic processes and phenotypic outcomes, (c) assume that genes are the only agents responsible for the transgenerational inheritance of phenotypic traits and characteristics, (d) assume that genes are self-contained and impervious to extragenetic influences, (e) posit a strong form of genetic determinism, or (f) pay lip service to the role of the environment. Building straw men and knocking them down is an inherently destructive enterprise; integrating different approaches is a more constructive way of contributing to the growth of knowledge.

Evolutionary Psychology From a Developmental Systems Perspective: Comment on Lickliter and Honeycutt (2003).

Although agreeing with R. Lickliter and H. Honeycutt (2003; see record 2003-09105-001) that evolutionary psychology lacks and should adopt a coherent developmental model to explain how evolved mechanisms become expressed in phenotypes, it is argued that adhering to the principles of developmental systems theory, despite enhancing evolutionary psychology, would not change appreciably its basic focus. The concepts of innateness and modularity, what is inherited and what evolves, as well as the possible role of developmental plasticity in the evolution of human cognition are discussed. It is proposed that evolutionary psychology can incorporate the developmental systems perspective into its theorizing, with the end result being a science that more closely reflects human nature.

A Prolegomenon for a Viable Evolutionary Psychology-The Myth and the Reality: Comment on Lickliter and Honeycutt (2003).

R. Lickliter and H. Honeycutt (2003; see record 2003-09105-001) attempted to create a dynamic developmental systems theory of evolutionary psychology. In this commentary, the author argues that the quality of their reasoning, their conflation of evolution and evolution by natural selection, their failure to explain the relative importance of multilevel, epigenetic interactions, their lack of population thinking, and their failure to define adaptation undermines their endeavor.

Genetic essentialism, neuroessentialism, and stigma: Commentary on Dar-Nimrod and Heine (2011).

Dar-Nimrod and Heine (2011) presented a masterfully broad review of the implications of genetic essentialism for understandings of human diversity. This commentary clarifies the reasons that essentialist thinking has problematic social consequences and links genetic forms of essentialism to those invoking neural essences. The mounting evidence that these forms of essentialist thinking contribute to the stigma of mental disorder is reviewed. Genetic and neuroessentialisms influence media portrayals of scientific research and distort how they are interpreted by laypeople. The common thread of these essentialisms is their tendency to deepen social divisions and promote forms of social segregation. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Building Information Modeling in Architecture, Engineering, and Construction: Emerging Research Directions and Trends

Currently, the architecture, engineering, and construction industry is facing enormous technological and institutional changes and challenges including the proliferation of information technology and appropriate application of sustainable practices. The 21st century engineer and architect must be able to deal with a rapid pace of technological change, a highly interconnected world, and complex problems that require multidisciplinary solutions. This paper focuses on research directions and trends around building information modeling (BIM) through interdisciplinary endeavors: how BIM research topics could be explored; their relevancy; and their potential future impact. It identifies BIM research topics that are considered to be important to a wide range of practitioners and future practitioners, both architecture and engineering students. It also assesses the relevance of current research projects to the industry and categorizes future BIM research topics. It aims to formulate research ideas and methodologies to pursue them and to explore how an industry/academic partnership for exploring exciting research opportunities could be established.     

Spinal Cord Injury Pain: Impact, Classification, Treatment Trends, and Implications From Translational Research.

Pain following spinal cord injury (SCI) has been recognized as a significant problem in the literature for over half a century. Prevalence estimates have varied widely, with most reports suggesting this to be an extremely common condition (60%-90%). Severe pain is reported by perhaps 25%, but for these persons, pain is literally the "insult added to injury." Effective treatments with a substantial body of empirical support did not exist until recently, and research progress has been compromised by lack of a standardized method for classifying and assessing pain. Encouraging developments for both assessment and treatment have occurred and are reviewed. There have been parallel developments in research using animal models of SCI pain that argue for exploration of translational work from animals to humans. Areas of research in which psychologists have been active and/or could become active are reviewed, both in clinical and translational research arenas.

Genes, Environment, and Race: Quantitative Genetic Approaches.

Understanding the origins of racial health disparities is currently a central focus of health-oriented funding agencies and the health policy community. In particular, the role of genetics in the origin of racial health disparities is receiving growing attention and has been susceptible to considerable misinterpretation. In this article, the authors provide a basic discussion about the concept of genes and race, an introduction to quantitative genetics, and some examples of quantitative genetic analyses of health conditions in an underserved population. The intent is to outline the conceptual limitations of exclusivist views of either environmental or genetic determination and to emphasize the coaction and interaction of genes and environments in health.

Rater biases in genetically informative research designs: Comment on Bartels, Boomsma, Hudziak, van Beijsterveldt, and van den Oord (2007).

Rater biases are of interest to behavior genetic researchers, who often use ratings data as a basis for studying heritability. Inclusion of multiple raters for each sibling pair (M. Bartels, D. I. Boomsma, J. J. Hudziak, T. C. E. M. van Beijsterveldt, & E. J. C. G. van den Oord, see record 2007-18729-006) is a promising strategy for controlling bias variance and may yield information about sources of bias in heritability studies. D. A. Kenny's (2004) PERSON model is presented as a framework for understanding determinants of rating reliability and validity. Empirical findings on rater bias in other contexts provide a starting point for addressing the impact of rater-unique perceptions in heritability studies. However, heritability studies use distinctive rating designs that may accentuate some sources of bias, such as rater communication and contrast effects, which warrant further study.

Age changes in personality and their origins: Comment on Roberts, Walton, and Viechtbauer (2006).

Comments on the original article "Patterns of Mean-Level Change in Personality Traits Across the Life Course: A Meta-Analysis of Longitudinal Studies," by B. W. Roberts, K. W. Walton, and W. Viechtbauer (see record 2006-00818-001). Although Roberts et al depicted the present authors as proponents of the immutability of traits, in fact we have always acknowledged the possibility of change, and we are pleased that the results of their meta-analysis are consistent with our conclusions about modest change after age 30. We agree with B.W. Roberts et al that analyses should be conducted at the level of more specific traits, but prefer the 30 facets of the Revised NEO Personality Inventory to the Social Dominance-Social Vitality distinction. The origins of age changes might be found either in environmental influences common to all cultures or in biologically based intrinsic maturation; we offer some reasons for preferring the latter interpretation. Meta-analyses are useful but not definitive, and the resolution of the origin question lies in further research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On the Need for a New Psychotherapy Research Paradigm: Comment on Westen, Novotny, and Thompson-Brenner (2004).

Basic, process, and outcome research have the potential to inform clinical practice. However, as D. Westen, C. M. Novotny, and H. Thompson-Brenner (2004; see record 2004-15935-005) observed in their timely analysis, the current dominant paradigm for psychotherapy outcome research--the randomized clinical trial--is not fulfilling this potential. The field's reliance on the medical model and manual-based interventions has contributed to the gap between research and clinical practice. Greater collaboration between practitioners and researchers, a focus on therapeutic principles rather than treatment packages, and systemic changes in how scholarly efforts are reinforced are needed to shift the current research paradigm.

Heredity, environment, and race differences in IQ: A commentary on Rushton and Jensen (2005).

J. P. Rushton and A. R. Jensen (see record 2005-03637-001) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black-White IQ gap. A dispassionate reading of the evidence on the association of IQ with degree of European ancestry for members of Black populations, convergence of Black and White IQ in recent years, alterability of Black IQ by intervention programs, and adoption studies lend no support to a hereditarian interpretation of the Black-White IQ gap. On the contrary, the evidence most relevant to the question indicates that the genetic contribution to the Black-White IQ gap is nil.

Research on Gossip: Taxonomy, Methods, and Future Directions.

A half century of gossip research from multiple disciplines is reviewed. Discussed are definitions of the construct: social, evolutionary, and personal functions of the practice; and data collection methods. Though people engage in the practice frequently, there has been relatively little psychological research on gossip. The layperson's understanding of the term is included in, but insufficient to encompass, definitions used by researchers. Most data are ethnographic and discursive, and few parametric data exist. The area could benefit from better experimental methods and instruments. Neurobiological and social network analysis methods are promising foundations for further study. There are real-world implications for understanding gossip. Strengthening gossip theory and research methods will beneficially inform the way we view the practice in context.

Theory and Research on Practices, Theory and Research as Practices: Hermeneutics and Psychological Inquiry.

What are the implications for theory and research in psychology of a hermeneutic perspective that takes practices as its starting point notion? The author addresses this wide-ranging issue by considering a number of specific questions in turn, including, among others, whether the hermeneutic perspective leads to rejecting systematic, quantitative research methods; whether it leads to the conclusion that efforts at theory and research provide us with an understanding of human behavior that is arbitrary; and whether a practices-based perspective points to a way of pursuing inquiry in psychology that is better than proceeding along the lines of mainstream psychology. The answers to these questions include a number of surprises, especially regarding how the hermeneutic perspective contrasts with mainstream psychology and how it differs from social constructionism. The author also identifies challenging issues for adherents of the hermeneutic perspective, including, in particular, issues concerning the limits of what we can know about psychological phenomena.

Experimental Research on Just-World Theory: Problems, Developments, and Future Challenges.

M. J. Lerner (1980) proposed that people need to believe in a just world; thus, evidence that the world is not just is threatening, and people have a number of strategies for reducing such threats. Early research on this idea, and on just-world theory more broadly, was reviewed in early publications (e.g., M. J. Lerner, 1980; M. J. Lerner & D. T. Miller, 1978). In the present article, focus is directed on the post-1980 experimental research on this theory. First, 2 conceptualizations of the term belief in a just world are described, the typical experimental paradigms are explained, and a general overview of the post-1980 experiments is provided. Second, problems with this literature are discussed, including the unsystematic nature of the research. Third, important developments that have occurred, despite the problems reviewed, are described. Finally, theoretical challenges that researchers should address if this area of inquiry is to advance in the future are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
