Direct gaze modulates face recognition in young infants

From birth, infants prefer to look at faces that engage them in direct eye contact. In adults, direct gaze is known to modulate the processing of faces, including the recognition of individuals. In the present study, we investigate whether direction of gaze has any effect on face recognition in four-month-old infants. Four-month infants were shown faces with both direct and averted gaze, and subsequently given a preference test involving the same face and a novel one. A novelty preference during test was only found following initial exposure to a face with direct gaze. Further, face recognition was also generally enhanced for faces with both direct and with averted gaze when the infants started the task with the direct gaze condition. Together, these results indicate that the direction of the gaze modulates face recognition in early infancy.     

Evaluating the Effectiveness of the Self‐Administered Interview© for Witnesses with Autism Spectrum Disorder

The widely used evidence‐based police interviewing technique, the Cognitive Interview, is not effective for witnesses with autism spectrum disorder (ASD). The present study examined whether a modification of the Cognitive Interview that removes the social element, the Self‐Administered Interview^©, is more useful in facilitating recall by ASD witnesses. One of the main components of the Cognitive Interview is context reinstatement, where the witness follows verbal instructions from the interviewer to mentally recreate the personal and physical context that they experienced during the event. The present findings showed that this procedure is not effective for witnesses with ASD in SAI format in which the social component of its administration is removed. However, the SAI sketch plan component did elicit more correct details from the ASD group, although to a lesser degree than for the comparison group. Theoretical and practical implications of the findings are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Brain hyper‐connectivity and operation‐specific deficits during arithmetic problem solving in children with developmental dyscalculia

Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who were matched on age, IQ, reading ability, and working memory. Children with DD were slower and less accurate during problem solving than TD children, and were especially impaired on their ability to solve subtraction problems. Children with DD showed significantly greater activity in multiple parietal, occipito‐temporal and prefrontal cortex regions while solving addition and subtraction problems. Despite poorer performance during subtraction, children with DD showed greater activity in multiple intra‐parietal sulcus (IPS) and superior parietal lobule subdivisions in the dorsal posterior parietal cortex as well as fusiform gyrus in the ventral occipito‐temporal cortex. Critically, effective connectivity analyses revealed hyper‐connectivity, rather than reduced connectivity, between the IPS and multiple brain systems including the lateral fronto‐parietal and default mode networks in children with DD during both addition and subtraction. These findings suggest the IPS and its functional circuits are a major locus of dysfunction during both addition and subtraction problem solving in DD, and that inappropriate task modulation and hyper‐connectivity, rather than under‐engagement and under‐connectivity, are the neural mechanisms underlying problem solving difficulties in children with DD. We discuss our findings in the broader context of multiple levels of analysis and performance issues inherent in neuroimaging studies of typical and atypical development.     

Eyewitness Evidence Obtained with the Self‐Administered Interview© Is Unaffected by Stress

The Self‐Administered Interview© (SAI) serves to elicit eyewitness statements directly after the crime. Witnesses could still experience stress then. Because stress during retrieval produces memory‐impairing effects, this study sought to compare the SAI with free recall under stress. An interaction between stress and interview was expected such that the SAI would elicit more comprehensive accounts than free recall in the control, but not in the stress group. One hundred and twenty‐seven participants underwent a stress or control task. They witnessed a live staged crime and completed an SAI or a free recall. The SAI elicited a higher number of correct verifiable event details and a higher number of correct and incorrect perpetrator details than free recall. Accuracy rates were unaffected. Unexpectedly, despite causing moderate stress‐induced cortisol elevations, stress exposure did not influence memory performance and did not interact with interview type. Hence, the SAI can safely be used, when witnesses are moderately stressed.Copyright © 2015 John Wiley & Sons, Ltd.     

Ethnic Identity in Emerging Adults in Sub‐Saharan Africa and the USA,and Its Associations with Psychological Well‐Being

Ethnic identity as a social dimension of identity is argued to be developmentally important for psychological well‐being. However, the relationships between these constructs are mainly examined in Western contexts, amongst dominant–non‐dominant groups. We investigate ethnic identity across the mainstream group of a prototypical Western society (the USA) and several multi‐ethnic sub‐Saharan African countries (Cameroon, Kenya, South Africa, and Zambia), as well as how it relates to psychological well‐being. A total of 1255 university students (61.8% females, M_age = 20.94 years, SD = 2.97) completed a questionnaire with ethnic identity and psychological well‐being measures. Results indicated that ethnic identity was most salient in two different South African ethnocultural samples and least salient in a mainstream US sample. These results suggest that groups that are more exposed to ethnic strain in multicultural societies tend to have more salient ethnic identities. Furthermore, the underlying structure in the ethnic identity psychological well‐being relationship was similar across groups. Copyright © 2015 John Wiley & Sons, Ltd.     

The neurodevelopmental basis of math anxiety

Math anxiety is a negative emotional reaction to situations involving mathematical problem solving. Math anxiety has a detrimental impact on an individual's long-term professional success, but its neurodevelopmental origins are unknown. In a functional MRI study on 7- to 9-year-old children, we showed that math anxiety was associated with hyperactivity in right amygdala regions that are important for processing negative emotions. In addition, we found that math anxiety was associated with reduced activity in posterior parietal and dorsolateral prefrontal cortex regions involved in mathematical reasoning. Multivariate classification analysis revealed distinct multivoxel activity patterns, which were independent of overall activation levels in the right amygdala. Furthermore, effective connectivity between the amygdala and ventromedial prefrontal cortex regions that regulate negative emotions was elevated in children with math anxiety. These effects were specific to math anxiety and unrelated to general anxiety, intelligence, working memory, or reading ability. Our study identified the neural correlates of math anxiety for the first time, and our findings have significant implications for its early identification and treatment.     

Challenge me! Communicating in multicultural classrooms

The current study investigated the value of Socratic classroom communication (e.g., critical debate and challenging each other on content matters) among students from various cultures (clustered into Western Europeans, Eastern Europeans and Non-Europeans) and from members of faculty at an international university in Germany. Students from Western cultures where Socratic communication had been valued in the school systems reported a greater ease of engaging in the respective communication style than did Eastern European and Non-European students. Furthermore, we assessed how strongly the faculty valued the respective kinds of behavior. The results show that overall students underestimated the extent to which Socratic communication behavior was esteemed by members of faculty. In addition, faculty members perceived themselves to be more explicit about their pedagogical principles than they were perceived by students. Finally, the easier it was for students to show Socratic classroom communication, the more academically satisfied they were and the better their grades. The results are discussed with regard to practical implications and the internationalization of universities.     

A comparison of video and static photo lineups with child and adolescent witnesses

In the UK video parades are the preferred method of identification employed in criminal cases. This policy implementation has been employed with little or no evidence concerning its validity. The reported research examines the effect of new video technology on children's identification evidence. The study compared 7–9 and 13–15‐year olds' ability to make identifications from either video or static photo lineups. Two hundred and fifteen participants witnessed a live event and then after a delay of 2–3 days viewed a target present (TP), or target absent (TA) video or photo lineup. For video and photo TP lineups, correct responses did not differ as a function of age. Video lineups produced lower rates of false identifications for the TA lineups, but only for adolescent witnesses. It is concluded that there is nothing contra‐indicated in the use of video identification procedures with children, and possibly certain benefits can accrue from its use.
