Charles Darwin and psychology at the bicentennial and sesquicentennial: An introduction.

This article provides an introduction to the special issue on Darwin and psychology at the bicentennial of his birth and the sesquicentennial of his publication of On the Origin of Species. His core contributions, as viewed today, were his theory of natural selection, his naturalistic philosophy, and his mass of evidence for evolutionary change. A brief summary of Darwin's life is also presented. Among Darwin's contributions to psychology were his demonstration of the continuity of species, a model for the study of instinct, a book on the expression of the emotions, and a baby biography. Previous celebrations of Darwin and the changing perceptions of his work since its publication are described. Darwin's theory remains an important part of psychology.

Scientists are not deficient in mental imagery: Galton revised.

In 1880, Galton carried out an investigation of imagery in a sample of distinguished men and a sample of nonscientists (adolescent male students). He concluded that scientists were either totally lacking in visual imagery or had "feeble" powers of mental imagery. This finding has been widely accepted in the secondary literature in psychology. A replication of Galton's study with modern scientists and modern university undergraduates found no scientists totally lacking in visual imagery and very few with feeble visual imagery. Examination of Galton's published data shows that his own published data do not support his claims about deficient visual imagery in scientists. The modern data for scientists and nonscientists and the 1880 data for scientists and nonscientists are in agreement in showing that all groups report substantial imagery on recollective memory tasks such as Galton's breakfast questionnaire. We conclude that Galton's conclusions were an example of theory-laden interpretation of data based on the initial responses from several very salient scientists who reported little or no visual imagery on Galton's imagery questionnaire.

The great struggles of life: Darwin and the emergence of evolutionary psychology.

Darwin envisioned a scientific revolution for psychology. His theories of natural and sexual selection identified two classes of struggles--the struggle for existence and the struggle for mates. The emergence of evolutionary psychology and related disciplines signals the fulfillment of Darwin's vision. Natural selection theory guides scientists to discover adaptations for survival. Sexual selection theory illuminates the sexual struggle, highlighting mate choice and same-sex competition adaptations. Theoretical developments since publication of On the Origin of Species identify important struggles unknown to Darwin, notably, within-families conflicts and conflict between the sexes. Evolutionary psychology synthesizes modern evolutionary biology and psychology to penetrate some of life's deep mysteries: Why do many struggles center around sex? Why is social conflict pervasive? And what are the mechanisms of mind that define human nature? (PsycINFO Database Record (c) 2010 APA, all rights reserved)

"The relationship between advanced age and mental abilities": Erratum.

Reports an error in the original article by Charles R. Strother, K. Warner Schaie, and Paul Horst (Journal of Abnormal & Social Psychology, 1957[Sept], 55, 166-170. The cuts for Figs. 1 and 3 were erroneously transposed in printing. The graph labelled Fig. 1 is derived from the data shown in Table 4 and represents the corrected T-score values. The graph labelled Fig. 3 is derived from the data in Table 1 and shows the uncorrected values. (The following abstract of this article originally appeared in record 1959-03294-001). Scores on primary mental abilities, speed, memory, and motor rigidity were obtained from 50 college graduates ranging in age from 70 to 84 years. A cross sectional study demonstrates a differential decline in these abilities with advancing age. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relationship between coping and avoiding behavior and response to fear-arousing propaganda.

"Avoiders are unable to recognize tension-producing stimuli and relate them to themselves, while copers show the capacity to recognize such stimuli and relate them to themselves… . The results support the hypothesis that a strong fear appeal receives greater acceptance among copers than among avoiders… . The obtained pattern of acceptance is largely due to the marked differential effectiveness of the two appeals on the avoider group, and not as was originally predicted, to any differential acceptance by copers."

Biometrical genetics and behavior: Reanalysis of published data.

The techniques which can be used in the analysis of quantitative data by the methods of biometrical genetics are outlined. The need for achieving a suitable scale is noted. Data provided by experiments in psychogentics which are amenable to this type of analysis are reanalized in terms of additive, dominance and interaction components of variance.

The relationship between multisensory integration and IQ in children.

It is well accepted that multisensory integration has a facilitative effect on perceptual and motor processes, evolutionarily enhancing the chance of survival of many species, including humans. Yet, there is limited understanding of the relationship between multisensory processes, environmental noise, and children's cognitive abilities. Thus, this study investigated the relationship between multisensory integration, auditory background noise, and the general intellectual abilities of school-age children (N = 88, mean age = 9 years, 7 months) using a simple audiovisual detection paradigm. We provide evidence that children with enhanced multisensory integration in quiet and noisy conditions are likely to score above average on the Full-Scale IQ of the Wechsler Intelligence Scale for Children—Fourth Edition (WISC–IV). Conversely, approximately 45% of tested children, with relatively low verbal and nonverbal intellectual abilities, showed reduced multisensory integration in either quiet or noise. Interestingly, approximately 20% of children showed improved multisensory integration abilities in the presence of auditory background noise. The findings of the present study suggest that stable and consistent multisensory integration in quiet and noisy environments is associated with the development of optimal general intellectual abilities. Further theoretical implications are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Intergenerational transmission of relationship aggression: A prospective longitudinal study.

The present study examined whether physical and verbal aggression in the family of origin were associated with similar patterns of aggression in young adult couples. Hypotheses were tested using a sample of 213 focal individuals who were followed from adolescence to adulthood. Results suggested that aggression in the family when focal participants were adolescents predicted aggression with romantic partners when participants were adults. The association between interparental aggression and later aggression in adult romantic unions was partially mediated through parents' aggression to focal participants when they were adolescents. Both physical and verbal aggression revealed the same pattern of findings. All together, these findings are consistent with a developmental-interactional perspective (Capaldi & Gorman-Smith, 2003) concerning the developmental origins of aggression in intimate relationships.

Intelligence: Foundations and issues in assessment.

There is no more central topic in psychology than intelligence and intelligence testing. With a history as long as psychology itself, intelligence is the most studied and likely the best understood construct in psychology, albeit still with many “unknowns.” The psychometric sophistication employed in creating intelligence tests is at the highest level. The authors provide an overview of the history, theory, and assessment of intelligence. Five questions are proposed and discussed that focus on key areas of confusion or misunderstanding associated with the measurement and assessment of intelligence.

On not "giving psychology away": The Minnesota Multiphasic Inventory and public controversy over testing in the 1960s.

Psychological tests, especially the Minnesota Multiphasic Personality Inventory, became the center of public controversy and Congressional scrutiny during the 1960s. This unwanted attention actually helped American psychologists more than they imagined. Assisted by those on Capitol Hill, psychologists were able to defend their science in a manner that avoided imposed forms of public accountability. Social questions were reformulated as technical problems. The need to adjust intelligence and aptitude tests reinforced psychologists' control over them. Conversely, personality tests were not made more transparent and nonintrusive, unless psychologists thought these changes were scientifically necessary. This episode prompted tighter regulation of test use and demonstrated that traditional forms of testing were far too important to popularize and "give away."

Genetic influences on the overlap between low IQ and antisocial behavior in young children.

The well-documented relation between the phenotypes of low IQ and childhood antisocial behavior could be explained by either common genetic influences or environmental influences. These competing explanations were examined through use of the Environmental Risk Longitudinal Twin Study 1994-1995 cohort (Moffitt & the E-Risk Study Team, 2002) of 1,116 twin pairs and their families. Children's IQ was assessed via individual testing at age 5 years. Mothers and teachers reported on children's antisocial behavior at ages 5 and 7 years. Low IQ was related to antisocial behavior at age 5 years and predicted relatively higher antisocial behavior scores at age 7 years when antisocial behavior at age 5 years was controlled. This association was significantly stronger among boys than among girls. Genetic influences common to both phenotypes explained 100% of the low IQ-antisocial behavior relation in boys. Findings suggest that specific candidate genes and neurobiological processes should be tested in relation to both phenotypes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Meta-analysis of the relationship between risk perception and health behavior: The example of vaccination.

Background: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. Method: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. Results: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. Conclusions: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.

The etiology of associations between negative emotionality and childhood externalizing disorders.

Despite consistent documentation of associations between childhood negative emotionality and externalizing psychopathology, few genetically informative studies have investigated the etiology of that association. The goal of the current study was to delineate the etiology of the covariation of negative emotionality and childhood externalizing problems (e.g., oppositional defiant disorder, conduct disorder, inattention, and hyperactivity/impulsivity). Twin families were recruited from Georgia state birth records and completed parental report questionnaires of negative emotionality and common Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) child psychiatric disorders. Results suggest both genetic and environmental influences underlying negative emotionality and each externalizing symptom dimension, with additional evidence for sibling competition/rater contrast effects for inattention and hyperactivity/impulsivity. Bivariate model-fitting analyses indicated that a portion of the additive (43%–75%) and nonadditive (26%–100%) genetic influences underlying each symptom dimension was accounted for by the genetic influences underlying negative emotionality. Finally, an independent pathways model examining the etiology of the association between negative emotionality and the externalizing dimensions indicated that a substantial portion of the additive genetic, nonadditive genetic, and nonshared environmental influences underlying externalizing behavior is shared with negative emotionality.

The relationship between peer-play interactions in the family context and dimensions of school readiness for low-income preschool children.

Relationships between parental report of children's peer play at home and indicators of children's school readiness were examined. Behavior ratings and observational data were collected for 242 preschool children from a large urban Head Start program. Relationships between children's home-based, peer-play behaviors and 4 measures of children's classroom behaviors (i.e., school-based peer play, approaches to learning, self-regulation, and behavior problems) were analyzed using bivariate correlational and multivariate methods. Play competencies exhibited in the home environment were significantly associated with prosocial behavior in the classroom, motivation to learn, task persistence, and autonomy. Disruptive or disconnected play behaviors were significantly related to patterns of disruptive and dysregulated experiences in the classroom with peers and with the learning process.
