Conceptual Integration of Arithmetic Operations With Real‐World Knowledge: Evidence From Event‐Related Potentials

Research on language processing has shown that the disruption of conceptual integration gives rise to specific patterns of event‐related brain potentials (ERPs)—N400 and P600 effects. Here, we report similar ERP effects when adults performed cross‐domain conceptual integration of analogous semantic and mathematical relations. In a problem‐solving task, when participants generated labeled answers to semantically aligned and misaligned arithmetic problems (e.g., 6 roses + 2 tulips  = ? vs. 6 roses + 2 vases  = ?), the second object label in misaligned problems yielded an N400 effect for addition (but not division) problems. In a verification task, when participants judged arithmetically correct but semantically misaligned problem sentences to be “unacceptable,” the second object label in misaligned sentences elicited a P600 effect. Thus, depending on task constraints, misaligned problems can show either of two ERP signatures of conceptual disruption. These results show that well‐educated adults can integrate mathematical and semantic relations on the rapid timescale of within‐domain ERP effects by a process akin to analogical mapping.     

Children as Earwitnesses: Memory for Emotional Auditory Events

We examined the influence of age and emotionality of auditory stimuli on long‐term memory for environmental sound events. Sixty children aged 7–11 years were presented with two environmental sound events: an emotional car crash and a neutral event, someone brushing their teeth. The sound events comprised six individual environmental sounds, and the participants passively listened to the sound events through a headset. After a two‐week delay, participants performed a cued recall task and a recognition task. Independent of age, children were notably poor at recalling the sound events. Children recalled and recognized significantly more sounds from the emotional sound event than the neutral sound event. Additionally, the older children performed the recall task better than the younger children. The present findings confirm and expand the previously reported superiority of emotional material in memory.Copyright © 2016 John Wiley & Sons, Ltd.     

The effects of situational goal orientation and cultural learning values on team performance and adaptation to change

In this paper, we examine the unique effects of situational goal orientation and cultural learning values on team adaptation to change and the moderating role of cultural learning values in the relationship between goal orientation and team performance and adaptation. To do this, we conducted an experiment using a 2 × 2 × 2 repeated-measures factorial design, consisting of high and low levels of learning values, situational goal orientation (i.e., learning goals and performance goals). The experimental task involved two phases: we looked at team performance in Phase 1 and team adaptation to change in Phase 2. Forty 3-person teams were randomly assigned to four experimental conditions and all teams engaged in a complex bridge-planning task. Performance was measured in terms of the quality of the planned bridge. Results showed independent effects of situational goal orientation and cultural learning values on team performance and adaptation to change. Cultural learning values also moderated the relationship between goal orientation and performance and adaptation to change. Finally, the combination of learning goals and high learning values resulted in the highest levels of initial team performance (Phase 1) and adaptation to change and improved performance (Phase 2), as compared to all other examined conditions.     

Researching consumers in virtual worlds: a cyberspace odyssey

Following Belk's (1991) Consumer Behaviour Odyssey, the authors suggest the need for a new odyssey, one that focuses on consumers in virtual worlds. In this paper the authors discuss the relevance of virtual communities for marketers and how ethnographic research methods can be adapted to the online environment. The unique methodological problems, opportunities and ethical dilemmas for researchers are considered that online ethnography raises before an exploration of how discourse analysis can assist in the interpretation of data collected online.

Adult attunement and child availability: Interaction of mother and caregiver with three‐year‐old kibbutz children

Relationships of mother and nonmaternal caregiver with 33 three‐year‐old kibbutz toddlers were investigated. Attunement and intrusiveness of these caregivers in their contact with children were determined by analysis of discrete child–adult interactions rather than by a global assessment of their relationships. The validity of these adult attunement scores was examined first by comparison of the attunement and intrusiveness scores of mother and of caregiver, and second by determining their association with independent scores of child availability to each of these caregiving adults. Results tended to support the validity of the present measures of adult attunement to the child. They indicated that in cases of disagreement mothers were more attuned than nonmaternal caregivers to the signals of the child, and the level of adult attuned agreement to the child was positively associated with cooperative attempts of children to involve caregivers in their activities © 2000 Michigan Association for Infant Mental Health.     

Pointing with the left and right hands in congenitally blind children

Congenitally blind and blindfolded sighted children at ages of 6, 8, 10 and 12 years performed a pointing task with their left and right index fingers at an array of three targets on a touch screen to immediate (0 s) and delayed (4 s) instructions. Accuracy was greater for immediate than delayed pointing and there was an effect of delay for the orientation of the main axis of the pointing distribution in both groups, indicating distinct spatial representations with development such as ego- and allocentric frames of reference, respectively. The pointing responses of the blind covered less surface area indicating better overall accuracy as compared to the sighted blindfolded. The hands differed for four of the six precision and accuracy parameters. The right hand performed better and seemed relatively contextually oriented, whereas the responses of the left hand were closer to the body and egocentrically oriented. The elongation of the scatter of the pointing responses was greater for the boys and more allocentrically oriented, indicating gender differences in spatial representation. The study provides a first evidence of ego- and allocentric spatial frames of reference in congenitally blind children and an ability to point at targets with the left and right hands in the total absence of vision.     

Categorization and affect: evidence for intra-hemispheric interactions

Both emotional reactivity and categorization have long been studied within the framework of hemispheric asymmetry. However, little attempt has been made to integrate both research areas using any form of neuropsychological research, despite behavioral data suggesting a consistent relationship between affective and categorization processes. The primary goal of the current study was to examine the possibility of a laterally mediated interaction between emotional reactivity and the cognitive process of categorization. Using a split visual fields categorization task combined with affect inducing procedures, we hypothesized that the relationship between state affect and categorization would be dependent on the nature of state affect and on the hemisphere targeted. Results offered support for this hypothesis, showing that state affect related changes in categorization appeared only in the hemisphere commonly associated with both a specific affective state and categorization strategy employed. Findings are discussed in terms of possible evidence for a hemispheric arousal effect underlying the relationship between affect and categorization.     

Remembering object position in the absence of vision: egocentric, allocentric, and egocentric decentred frames of reference

In three experiments we examined whether memory for object locations in the peri-personal space in the absence of vision is affected by the correspondence between encoding and test either of the body position or of the reference point. In particular, the study focuses on the distinction between different spatial representations, by using a paradigm in which participants are asked to relocate objects explored haptically. Three frames of reference were systematically compared. In experiment 1, participants relocated the objects either from the same position of learning by taking as reference their own body (centred egocentric condition) or from a 90 degrees decentred position (allocentric condition). Performance was measured in terms of linear distance errors and angular distance errors. Results revealed that the allocentric condition was more difficult than the centred egocentric condition. In experiment 2, participants performed either the centred egocentric condition or a decentred egocentric condition, in which the body position during the test was the same as at encoding (egocentric) but the frame of reference was based on a point decentred by 90 degrees. The decentred egocentric condition was found to be more difficult than the centred egocentric condition. Finally, in experiment 3, participants performed in the decentred egocentric condition or the allocentric condition. Here, the allocentric condition was found to be more difficult than the decentred egocentric condition. Taken together, the results suggest that also in the peripersonal space and in the absence of vision different frames of reference can be distinguished. In particular, the decentred egocentric condition involves a frame of reference which seems to be neither allocentric nor totally egocentric.
