‘Liars are less detailed’ …So what? Comparing two recall instructions to detect deception within-subject

Most deception research provides between-subject results (e.g., liars give on average less detailed accounts), which might be of limited value for professionals evaluating credibility on an individual basis. This study examines the optimal instructions of a within-subject multiple recalls strategy to detect deception. A total of 110 participants, divided into a Lie and Truth group, were randomly placed into four interview conditions: two Basic report-everything instructions (1), a Basic recall followed by an Open depth instruction (2), a Basic recall followed by the Verifiability Approach and Information Protocol (3), and two recalls with the Verifiability Approach and Information Protocol (4). All recalls were coded for total details and verifiable details. Group (lie and truth) × Recall (first and second) was only significant in condition 3, with truth tellers providing more verifiable details in the second recall than the first. A simple within-subject decision rule was derived, allowing a 76.9% discrimination rate. Professionals can optimally evaluate credibility using two recalls (Basic recall followed by Verifiability Approach and Information Protocol) and observing the evolution of verifiable details.     

Child physical punishment,parenting, and school readiness

This study explored how physical punishment (PP) and other parenting approaches may predict school readiness outcomes. By using the Canada‐wide representative data, 5,513 children were followed over a 2‐year period. Caregivers reported on their use of PP and other parenting approaches (i.e., literacy and learning activities and other disciplinary practices) when children were 2–3 years old, whereas school readiness was measured at 4–5 years using interviewer‐administered tests of number competence and receptive vocabulary skills. Analyses controlled for PP use at 4–5 years, child externalizing behaviours, and various sociodemographics. Results indicated that PP does not directly predict school readiness; however, the effect of PP was moderated by other parenting approaches. Children's receptive vocabulary was weaker if caregivers used PP together with less frequent explaining/teaching regarding problem behaviour, or PP with less frequent engagement in literacy and learning activities. Children had weaker number competence when PP co‐occurred with more frequent psychological aggression (e.g., yelling/scolding). Results suggest that PP hinders children's school readiness when used alongside other parenting approaches, which reflects the reality of parenting (i.e., PP does not occur in isolation). Findings support early education efforts aimed at promoting early learning and literacy opportunities, as well as positive disciplinary strategies that do not involve PP.

Highlights

• We explored how physical punishment and other parenting approaches may predict school readiness outcomes using Canada‐wide data.
• Results provided little evidence of positive effects of physical punishment on school readiness across a range of parenting and disciplinary contexts.
• To promote school readiness, early education efforts should promote early learning opportunities and positive disciplinary strategies that do not involve physical punishment.

     

Regret and the negative evaluation of decision outcomes in major depression

Disruption of normal emotional experience is central to the phenomenology of depression. Twenty-three depressed outpatients and 23 control subjects performed a computerized decision-making task, during which affective ratings were assessed online to identify various dimensions of emotional experience. We sought to contrast regret (the comparison of the outcomes of selected and nonselected options) with the general negative appraisal of task events. The experience of regret was reduced in depressed patients, an effect that was particularly related to self-reported apathy scores. In an exploratory analysis, we observed that females had a general downward shift in their ratings, as compared with males, but disappointment and regret effects were of similar magnitude. The possible contribution of the orbitofrontal cortex to the phenomenology of regret is discussed.

Exploring the cognitive development of children born to adolescent mothers in South Africa

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10–19 years) and their first-born children (0–68 months). All adolescents completed questionnaires relating to themselves and their children, and standardized child cognitive assessments (Mullen Scales of Early Learning) were undertaken. Cognitive development scores of the sample were lower than USA reference population scores and relative performance compared to the reference population was found to decline with increasing child age. When compared to children born to adult mothers in the sub-Saharan African region, children born to adolescent mothers (human immunodeficiency virus [HIV] unexposed; n = 724) were found to have lower cognitive development scores. Findings identify critical periods of development where intervention may be required to bolster outcomes for children born to adolescent mothers.

Highlights

• An exploration of the cognitive development of children born to adolescent mothers within South Africa utilizing the Mullen Scales of Early Learning.
• Cognitive development scores of children born to adolescent mothers within South Africa were lower compared to USA norm reference data and declined with child age.
• Previous studies utilizing the Mullen Scales of Early Learning within sub-Saharan Africa were summarized, and comparisons were made with the current sample.
• Findings highlight a potential risk of developmental delay among children born to adolescent mothers compared to children of adult mothers in the sub-Saharan African region.

     

SEMANTIC INTEGRATION: A COMPARISON OF NORMAL AND DISABLED READERS

Abstract

This study examined comprehension of sets of related sentences from which inferences could be drawn. Subjects were 40 disabled and 40 normal readers (C.A. 10‐10 ‐ 11‐11) who were asked to read short paragraphs suggesting spatial relationships. After reading, they were given a recognition test containing items not previously read but which were structured in their relationship to the semantic content of the texts. Analyses of within and between group errors reveal significant differences due to sentence type and a strong tendency for both groups to “misrecognize” semantically congruent inferences. The results are discussed in light of past research on the memory capabilities of disabled readers and with respect to techniques of remediation.     

FLUENCY SNAPSHOTS: A QUICK SCREENING TOOL FOR YOUR CLASSROOM

In this article, the authors present a research-based, classroom tested assessment tool, the Classroom Fluency Snapshot (CFS). This assessment is grounded in the research that establishes fluency as an important component of initial reading instruction and in the work on the efficacy of curriculum based measurement. The article presents the case of one classroom in which a teacher uses the CFS as a pre-, post-assessment. Rich classroom examples, details of the teacher's interpretation, and instructional decision making are shared along with ideas for instruction.     

Newborns modulate their crawling in response to their native language but not another language

Human newborns can propel themselves to their mother's breast when positioned skin to skin on her abdomen just after birth. For decades, researchers have considered this primitive crawling behavior a spinal reflex, immune to supra spinal control. However, recent research suggests that neonatal crawling is already responsive to visual and olfactory stimuli processed at a supra spinal level. Here we report that a few hours post birth, French newborns can also modulate their crawling in response to their native language – a source of information that is processed supra-spinally. The crawling patterns of 23 French-born newborns were recorded on video and via an infrared motion capture system during two randomly ordered 2-min trials. The newborns were secured on a mini skateboard to facilitate arm and leg movements during their crawling propulsion. They heard a repetitive sequence of the same sentences either in French, their native language, or in English, a rhythmically different and hence discriminable unfamiliar language, on each trial. In French, compared to English, crawling was enhanced, with significantly more arm and leg steps and significantly more and larger trunk rotations in the cephalo-caudal axis. Moreover, newborns rotated their heads and trunk toward the appropriate loud speaker when hearing French but not English. These preliminary findings suggest that newborn crawling is not a simple stereotyped reflex under spinal control, but a complex pattern that can be modulated in response to higher-order, supra-spinally processed stimuli. The findings open fascinating questions about the range of stimuli to which newborn crawling is responsive.
