Considers that participants in previous deception detection experiments may not have had access to the types of information people most often use to detect real-life lies. Suggests that people most often rely on information from third parties and physical evidence when detecting lies, and that the detection of a lie is a process that takes days,…

Recorded reaching and looking preferences and movement kinematics among 5- to 15-month-olds divided into 3 age groups. Found that 5- to 12-month-olds preferred looking first at a large object; 8.5- to 12-month-olds showed preference for reaching to smaller (graspable) objects. Kinematic measures suggested that onset of object-oriented action…

Objective: To examine the transmission behavior among youth living with HIV (YLH), pre- and post-HAART. Methods: Two cohorts were recruited: (1) 349 YLH during 1994 to 1996 and (2) 175 YLH during 1999 to 2000, after the wide availability of HAART. Differences in sexual and substance-use risk acts and quality of life were examined. Results:…

Literature assessing knowledge of and attitudes toward social issues has demonstrated that mental health professionals and lay persons often differ greatly. To add to the normative information in the field of psychological abuse and to determine whether the differences previously found between mental health professionals and lay persons extend to…

The past two decades have seen an explosion in research in the fields of violence and trauma and behavior genetics. These two fields came into direct conflict when Lisabeth Fisher DiLalla and Irving I. Gottesman outlined a fundamental conceptual limitation of trauma and violence research: that rather than being causal, the well-documented…

A recent article in the "Journal of Deaf Studies and Deaf Education" (Leigh, Brice, & Meadow-Orlans, 2004) explored attachment between deaf mothers and their 18-month-old children and reported relationship patterns similar to those for hearing dyads. The study reported here explores a marker of early mother-child relationships: cradling…

Twenty-two- and 27-month-old children were tested for their understanding of pretending as a specific intentional action form. Pairs of superficially similar behaviors--pretending to perform an action and trying to perform that action--were demonstrated to children. The 27-month-olds, and to some degree the 22-month-olds, showed in their responses…

In contrast to the many published accounts of the disfluent repetition of sounds at the beginnings of words, cases where it is predominantly the final parts of words that are repeated have been reported relatively rarely. With few exceptions, those studies that have been published have described either pre-school children or neurologically…

Many statistical models have been used to study human development. The multidimensional scaling (MDS) method has been an under-utilised technique in psychological and educational research for studying such phenomena. In this paper, MDS profile analysis was used to examine adolescent mood change patterns over a 1-week period. This method is used to…

During the past 20 years, a significant body of literature has emerged focusing on the application of Dabrowski's theory of positive disintegration (TPD) to the study of gifted individuals. Although much of this literature is prescriptive, some research reports spanning this time period are available. A perusal of research on TPD's applicability…

A good deal is now known about the neural circuitry involved in how conditioned fear can augment a simple reflex (fear-potentiated startle). This involves visual or auditory as well as shock pathways that project via the thalamus and perirhinal or insular cortex to the basolateral amygdala (BLA). The BLA projects to the central (CeA) and medial…

A range of behavior--much deemed problematic by society--is treated with behavioral methods or psychotropic medications. Although the processes associated with behavioral interventions have been investigated using conceptual, experimental, and applied analyses, less is known about the behavioral processes associated with the use of psychotropic…

Gottlieb's (1991/2007) target article represents a milestone in our understanding of the impact of social experience on developmental malleability. Interactions across the species-typical and operant behavior categories are increasingly understood to exist. The social contingencies present in the normal species-typical developmental manifold are…

The role of parental communication and instruction concerning sexual behaviour were studied in a community-based sample of 1083 youth aged 13-17 (mean age of 15 years; 51% girls, 49% White). The Youth Asset Survey was administered along with items measuring demographics and youth risk behaviours. After controlling for demographic factors,…

This longitudinal study examined links between disorganization and atypical maternal behavior at 12 and 24 months in 71 adolescent mother-child dyads. Organized attachment and maternal not disrupted behavior were more stable than disorganization and disrupted behavior, respectively. At both ages, disorganization and maternal disrupted behavior…
