Purpose: This study examined whether the perceived taste intensity of liquids with chemesthetic properties influenced lingua-palatal pressures and submental surface electromyography (sEMG) in swallowing, compared with water. Method: Swallowing was studied in 80 healthy women, stratified by age group and genetic taste status. General Labeled…

Western participants consistently match certain shapes with particular speech sounds, tastes, and flavours. Here we demonstrate that the "Bouba-Kiki effect", a well-known shape-sound symbolism effect commonly observed in Western participants, is also observable in the Himba of Northern Namibia, a remote population with little exposure to…

Chaos in the home is a key environment in cognitive and behavioural development. However, we show that children's experience of home chaos is partly genetically mediated. We assessed children's perceptions of household chaos at ages 9 and 12 in 2337 pairs of twins. Using child-specific reports allowed us to use structural equation modelling to…

The present study examined the effects of age, gender, and causality on the perceptions of persons with mental retardation. Participants rated individuals with mental retardation using a semantic differential scale with three factors: activity, evaluation, and potency. Target individuals in each scenario varied on the variables of age (8, 20, 45),…

This report describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). Part I describes a classification extension to the SDCS to differentiate motor speech disorders from speech delay and to differentiate among three sub-types of motor speech disorders.…

Empirical data suggest that there is at most a very small sex difference in general mental ability, but men clearly perform better on visuospatial tasks while women clearly perform better on tests of verbal usage and perceptual speed. In this study, we integrated these overall findings with predictions based on the Verbal-Perceptual-Rotation (VPR)…

At the end of a biology course entitled Ecology, Evolution, and Genetics, students were asked to consider how their learning experience had changed their perception of either ecology or genetics. Students were asked to express their thoughts in the form of a "digital story" using readily available software to create movies for the purpose of…

The Annual Review of Psychology is compiled to provide authoritative evaluation of progress in both the traditional and the new areas of psychology. The 1971 edition includes the following topics and authors: Basic Drives, by Frank W. Finger and Douglas G. Mook; Behavioral Genetics, by Gardner Lindzey and others; Audition, by David H. Raab;…

Results indicated significant genetic influence on eight Family Environment Scales that had been altered to obtain retrospective perceptions of family environment in childhood. The combined twin and adoption design was used with four groups of twins whose average age was 59 years. (RH)

Insecure mental representations of attachment, a nearly invariant feature of cluster B personality disorders, have never previously been studied in twins. We conducted the Adult Attachment Interview (AAI) on 33 pairs of monozygotic (MZ) female twins reared together as an initial exploration of causal influences on mental representations of…

A BioLogica trial in six U.S. schools using interpretive approach is conducted by the Concord Consortium that examined the student motivation of learning genetics. Multiple data sources like online tests, computer data log files and classroom observation are used that found the result in terms of interviewees' perception, class-wide online…

Different genetic disorders predispose individuals to display specific, etiology-related profiles, personalities, and maladaptive behaviors. Using groups with genetic etiologies as stand-ins or proxies for a specific behavior or set of behaviors, one can then examine how others in the child's environment react and whether such reactions are…

The most popular activities from APA's successful "Activities Handbooks for the Teaching of Psychology" are gathered together and updated in this book of teachers' favorites. The lesson plans, which encourage active learning and involve the whole class, have stood the test of time and proven themselves to be entertaining, effective, and easy to…

The question as to whether males and females have different kinds of intellectual abilities is addressed. The evidence that there are some differences in cognition and perception between men and women is reviewed. (KR)

Determinants of Schaefer's (1965) three dimensions of perceived parenting (Acceptance vs. Rejection, Psychological Control vs. Psychological Autonomy, and Firm vs. Lax Control) were investigated by administering a shortened Children's Reports of Parental Behavior Inventory to adolescent twins. The sample consisted of 46 pairs of identical twins…
