Mobile technologies, such as QR codes, play a particularly important role in scaffolding the child user’s active learning in informal environments. The purpose of this paper is to examine the impact of QR code scanning on two informal learning outcomes: increased interest and greater knowledge understanding.

In total, 91 children and their families participated in the study as part of the iQ Zoo Project. Children in both the smartphone group and the control group completed were assessed qualitatively and quantitatively before and then after their zoo visits.

Qualitative findings suggest that most children’s interest in learning about animals was sustained as a result of the experience. Quantitative results reveal that QR code scanning was effective in promoting knowledge gains, especially on subjects that are challenging for the informal learner. Findings were comparable across the younger (5–8) and older (9–12) age groups.

This study provides empirical support for the value and usefulness of mobile technologies such as QR code scanning for children's learning in informal environments.

Deception detection is instrumental in business management but professionals differ widely in terms of deception detection performance. The purpose of this paper is to examine the genetic basis of deception detection performance using the classic twin study design and address the research question: how much variance in individual differences in deception detection performance can be accounted for by the variance in genetics vs environmental influences?

In total, 192 twins, with 65 pairs of monozygotic (identical) twins and 31 pairs of dizygotic (fraternal) twins participated in an experiment. A series of behavioral genetic analyses were performed.

The variability in deception detection performance was largely determined by differences in shared and non-shared environments.

The subjects were solicited during the Twins Days Festival so the sample selection and data collection were limited to the natural settings in the field. In addition, the risks and rewards associated with deception detection performance in the study are pale in comparison with those in practice.

Deception detection performance may be improved through training programs. Corporations should continue funding training programs for deception detection.

This is the first empirical study that examines the complementary influences of genetics and environment on people’s ability to detect deception.
