Brain activation during spatial updating and attentive tracking of moving targets

Keeping aware of the locations of objects while one is moving requires the updating of spatial representations. As long as the objects are visible, attentional tracking is sufficient, but knowing where objects out of view went in relation to one's own body involves an updating of spatial working memory. Here, multiple object tracking was employed to study spatial updating and its neural correlates. In a dynamic 3D-scene, targets moved among visually indistinguishable distractors. The targets and distractors either stayed visible during continuous viewpoint changes or they turned invisible. The parametric variation of tracking load revealed load-dependent activations of the intraparietal sulcus, the superior parietal lobule, and the lateral occipital cortex in response to the attentive tracking task. Viewpoint changes with invisible objects that demanded retention and updating produced load-dependent activation only in the precuneus in line with its presumed involvement in updating spatial working memory.     

Profiles of anger control in second-grade children: examination of self-report, observational, and physiological components

The current study used latent profile analysis (LPA) to examine anger control in 257 second-grade children (∼8 years of age). Anger was induced through losing a game and prize to a confederate who cheated. Three components of anger control were assessed: self-report of awareness of anger, observed intensity of angry facial expressions, and skin conductance reactivity. These components served as indicators in an LPA conducted to determine whether distinct groups of children who differed in anger control profiles would emerge. Five groups were found: (a) Physiology-and-Expression Controllers (high self-report, low expression, low physiological arousal), (b) Expression-Only Controllers (high self-report, low expression, high physiological arousal), (c) Non-controllers (high self-report, high expression, medium physiological arousal), (d) Non-reactive (low self-report, low expression, low physiological arousal), and (e) Non-reporters (low self-report, medium expression, medium physiological arousal). These findings are discussed in terms of implications for the assessment of children’s anger control skills and intervention programs for children’s anger management.     

Understanding children's emotional processes and behavioral strategies in the context of marital conflict

Marital conflict is a distressing context in which children must regulate their emotion and behavior; however, the associations between the multidimensionality of conflict and children’s regulatory processes need to be examined. The current study examined differences in children’s (N = 207, mean age = 8.02 years) emotions (mad, sad, scared, and happy) and behavioral strategies to regulate conflict exposure during resolved, unresolved, escalating, and child-rearing marital conflict vignettes. Children’s cortisol levels were assessed in relation to child-rearing and resolved conflict vignettes. Anger and sadness were associated with escalating and child-rearing conflicts, fearfulness was related to escalating and unresolved conflicts, and happiness was associated with resolution. Anger was associated with children’s strategies to stop conflict, whereas sadness was associated with monitoring and avoidant strategies. Cortisol recovery moderated the link between fearfulness and behavioral regulation. These results highlight the importance of children’s emotions and regulatory processes in understanding the impact of marital conflict.     

Gender differences in subjective well-being, self-esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: findings from the Nord-Trøndelag Health Study

Derdikman‐Eiron, R., Indredavik, M. S., Bratberg, G. H., Taraldsen, G., Bakken, I. J. & Colton, M. (2011). Gender differences in subjective well‐being, self‐esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: Findings from the Nord‐Trøndelag health study. Scandinavian Journal of Psychology52, 261–267. Gender differences in the prevalence of symptoms of anxiety and depression during adolescence are well documented. However, little attention has been given to differences in subjective well‐being, self‐esteem and psychosocial functioning between boys and girls with symptoms of anxiety and depression. The aim of this study was to investigate gender differences in the associations between such symptoms and subjective well‐being, self‐esteem, school functioning and social relations in adolescents. Data were taken from a major population‐based Norwegian study, the Nord‐Trøndelag Health study (HUNT), in which 8984 (91% of all invited) adolescents, aged 13–19 years, completed an extensive self‐report questionnaire. Although prevalence rates of symptoms of anxiety and depression were higher in girls than in boys, a significant interaction between gender and symptoms of anxiety and depression was found in respect of each of the following outcome variables: subjective well‐being, self‐esteem, academic problems, frequency of meeting friends and the feeling of not having enough friends. These interactions indicate that the associations between symptoms of anxiety and depression and lower subjective well‐being and self‐esteem, more academic problems in school and lower social functioning were stronger for boys than for girls. Our findings may contribute to an earlier assessment and more efficient treatment of male adolescent anxiety and depression.     

Peer pressure against prejudice: A high school field experiment examining social network change

Individuals often conform to the intergroup attitudes and behaviors modeled by their peers in a given situation. To what extent does peer influence on intergroup prejudice 1) diffuse across a social network of peers and 2) affect attitudes and behavior across time? Student leaders (“Peer Trainers”) were trained to confront expressions of intergroup prejudice in five randomly assigned high schools across a period of five months; students recruited to be Peer Trainers in five control schools waited to be trained. Independent surveys of Peer Trainers' social networks reveal that treatment Peer Trainers were significantly more likely than control Trainers to be nominated by peers as students who confront prejudice. Treatment Peer Trainers' tolerant behavior spread to close friends and to acquaintances in their social network; their attitudes spread inconsistently, and only to close friends. Studying peer influence within social networks can improve understanding of social influence, prejudice reduction, and social change.     

The promise and potential of studying the “invisible hand” of teacher influence on peer relations and student outcomes: A commentary

Peers influence children's social-emotional development and school engagement in important and unique ways. Recent research on peer social networks documents that children are affected by the nature of the school-based peer ecology, as well as by their personal peer experiences. Yet, little is known about how teachers affect the peer ecology, nor how teachers can promote positive peer influences in the school context. The four studies in this special section examine this issue. Together, they document the promise and the potential of studying the “invisible hand” of teacher influence on peer relations, and illustrate the need for further research in this area. This commentary considers the contributions of these papers for conceptualizing processes of transactional teacher and peer influence on student outcomes, and implications for interventions designed to reduce problem behaviors or increase school engagement. In addition, it considers the limitations of current knowledge and directions for future research.     

Effects of the global and local attention on the processing of categorical and coordinate spatial relations

Participants made categorical or coordinate spatial judgments on the global or local elements of shapes. Stimuli were composed of a horizontal line and two dots. In the Categorical task, participants judged whether the line was above or below the dots. In the Coordinate task, they judged whether the line would fit between the dots. Stimuli were made hierarchical so that the global patterns composed of a “global line” made of local dots-and-line units, and “global dot” made of a single dots-and-line unit. The results indicated that the categorical task was better performed when participants attended to the local level of the hierarchical stimuli. On the other hand, the coordinate task was better performed when they attended to the global level. These findings are consistent with computer simulation models of the attentional modulation of neuronal receptive fields’ size suggesting that (1) coordinate spatial relations are more efficiently encoded when one attends to a relatively large region of space, whereas (2) categorical spatial relations are more efficiently encoded when one attends to a relatively small region of space.     

Intentional transaction

The second person is often set in contrast to the first person. And there is a contrast. It does not reside in a difference of what is thought as I from what is thought as you. For that is not different. The contrast is that of monadic and dyadic predication, action and transaction. It is the contrast, not of I and You, but of I and I–You. The second person does not add a You to an I. It divides the I and makes it a relation. We consider, first, the form of predication that is common to first- and second-person thought. Then, we define the second person as a species of this form of thought. Last, we find the source and condition of this form of thought in a thought of this very form. This thought, being the source of its own form, is one of which one cannot be conscious from outside it. It is a last word, or, better, a first word.¹1. Compare Thomas Nagel's notion of a last word (Nagel 2001 Nagel, Thomas. 2001. The Last Word. Oxford: Oxford University Press. [Google Scholar]). Nagel's development of the notion reveals no reason why he should call what is last a word. From what he writes in the book, one would think its title to be “The Last Thought”. (Indeed, chapter 2 bears the title “Why We Can't Understand Thought from the Outside”.) However, if the last thought is I–You, then the last thought is a word; indeed, it is the word. In reaching for “The Last Word”, Nagel may express an inchoate appreciation of this.     

现实场景典型空间位置关系客体的解码效应

通过探讨典型空间关系客体对中单个客体的视觉工作记忆,考察空间位置关系的解码特征和主动客体记忆优势。结果发现：（1）当客体以符合空间位置关系方式呈现时,记忆更准确;（2）符合空间位置关系条件下单个客体提取反应时更长,上方客体反应时更短,记忆更准确;（3）兼具空间位置关系与动作关系客体对中的主动客体记忆正确率更高。结果表明,现实场景客体空间分组中单个客体提取时存在解码现象和顺序效应,对现实中的上方与主动客体存在加工偏好。     

Anticipatory looks reveal expectations about discourse relations

Previous research provides evidence for expectation-driven processing within sentences at phonological, lexical, and syntactic levels of linguistic structure. Less well-established is whether comprehenders also anticipate pragmatic relationships between sentences. To address this, we evaluate a unit of discourse structure that comprehenders must infer to hold between sentences in order for a discourse to make sense—the intersentential coherence relation. In a novel eyetracking paradigm, we trained participants to associate particular spatial locations with particular coherence relations. Experiment 1 shows that the subset of listeners who successfully acquired the location∼relation mappings during training subsequently looked to these locations during testing in response to a coherence–signaling intersentential connective. Experiment 2 finds that listeners’ looks during sentences containing coherence-biasing verbs reveal expectations about upcoming sentence types. This work extends existing research on prediction beyond sentence-internal structure and provides a new methodology for examining the cues that comprehenders use to establish relationships at the discourse level.
