中央线索化对听觉障碍人群辨别任务返回抑制的影响

选取一组先天聋被试和与之匹配的听力正常被试,采用线索提示范式考察中央线索化对听觉障碍被试在辨别任务中基于位置返回抑制的影响。实验结果发现,在有中央线索化的任务实验中,听力正常和听觉障碍被试都出现了返回抑制,但是听觉障碍被试消失得比听力正常被试早。无中央线索化的辨别任务实验中,听力正常被试组仅在SOA=650ms时,听觉障碍被试没有发现返回抑制现象。结果表明听觉障碍被试辨别任务的返回抑制更易受中央线索化条件的影响,听障被试的空间注意调节机制更具策略性和有效性。     

The dialogical self in a cultural contact zone: Exploring the perceived ‘cultural correction’ function of schooling

This paper discusses a qualitative study that explores the impact the development of a cultural contact zone has upon identity processes in the Dialogical Self. The analysis draws upon interviews with Irish nationals, immigrants and asylum seekers in a new cultural contact zone. The findings illustrate uncertainty experienced as a result of immigration, suggesting that the development of the contact zone caused cultural discontinuity. The individuals' uncertainty for their cultural identities' future viability demanded the development of identity strategies to maintain continuity with their perceived cultural future, where they were faced with cultural others. Identity repositionings and a strategy to maintain continuity will be explored in the current paper. The Irish and asylum seeker participants' unprompted focus on schooling will be explored as a continuity strategy. The participants constructed schooling as a tool for the ‘cultural correction’ of migrant children and a means for the assimilation of migrants into the Irish community. The paper discusses the function of this strategy for the two groups, and the theoretical integration of cultural level processes in the theory of the Dialogical Self.

Alternative settings for liberal‐conservative exchange: Examining an undergraduate dialogue course

Given the polarization of the early 21st century political atmosphere in the U.S., intergroup dialogue has emerged as a unique alternative setting, with intentions of facilitating a more productive and thoughtful citizen engagement. Although cross‐partisan dialogue efforts are underway in community contexts, they have been slower to reach academic settings. This paper is an exploratory study of our own liberal‐conservative dialogue course at the University of Illinois–the first of its kind, to our knowledge. After describing basic features of the course, we identify themes from student journals and final evaluations suggesting both dialogue benefits and challenges. Finally, we discuss the growing literature around dialogue, questions of its long‐term impact, and larger potential barriers to participation in liberal‐conservative dialogue, specifically.

Elaboration and numerical anchoring: Implications of attitude theories for consumer judgment and decision making

Researchers across many domains have examined the impact of externally presented numerical anchors on perceiver judgments. In the traditional paradigm, “anchored” judgments are typically explained as a result of elaborate thinking (i.e., confirmatory hypothesis testing that selectively activates anchor-consistent information in memory). Consistent with a long tradition in attitude change, we suggest that the same judgments can result from relatively thoughtful or non-thoughtful processes, with more thoughtful processes resulting in judgments that have more lasting impact. We review recent anchoring research consistent with this elaboration-based perspective and discuss implications for past anchoring results and theory in judgment and decision making.     

Effect of video self‐monitoring on procedural integrity

A video self‐monitoring treatment package was used to evaluate the procedural integrity of staff implementing behavioral guidelines for one child with autism. Staff members with low procedural integrity scores were asked to participate. The treatment package incorporated an implementation video which reviewed the relevant behavioral guidelines and a procedural integrity monitoring system. Each participant was taught to score a pre‐training video, which highlighted components of implementing behavioral guidelines, with a procedural integrity tool denoting correct implementation of the procedures. The participant then scored their own baseline video using a similar tool constructed to highlight the target student's behavior plan. Participant scores were compared to experimenter scores and verbal feedback was given by the experimenter if the scores varied. Results showed increased procedural integrity implementing the behavior guidelines from baseline to 100% implementation for two out of three participants.

Love imagined: Working models of future romantic attachment in emerging adults

An attachment theory perspective guided this investigation of emerging adults' (N = 174) expectations regarding relational patterns in their future long‐term romantic relationships. Participants' working models of future romantic attachment were assessed by having them respond to an attachment measure with respect to an imagined future committed relationship. Dimensions of future attachment predicted participants' anticipated relationship dynamics in the imagined relationship, their focus on closeness and abandonment when writing about having a future long‐term relationship, and their change in state anxiety over the course of the study. These effects of future attachment remained statistically significant after controlling for current global attachment, parental caregiving sensitivity, and conflict between parents; most of these effects were not moderated by current dating status.     

Nonword repetition in children and adults: effects on movement coordination

Hearing and repeating novel phonetic sequences, or novel nonwords, is a task that taps many levels of processing, including auditory decoding, phonological processing, working memory, speech motor planning and execution. Investigations of nonword repetition abilities have been framed within models of psycholinguistic processing, while the motor aspects, which also are critical for task performance, have been largely ignored. We focused our investigation on both the behavioral and speech motor performance characteristics of this task as performed in a learning paradigm by 9‐ and 10‐year‐old children and young adults. Behavioral (percent correct productions) and kinematic (movement duration, lip aperture variability – an index of the consistency of inter‐articulator coordination on repeated trials) measures were obtained in order to investigate the short‐term (Day 1, first five vs. next five trials) and longer‐term (Day 1 vs. Day 2, first five vs. next five trials) changes associated with practice within and between sessions. Overall, as expected, young adults showed higher levels of behavioral accuracy and greater levels of coordinative consistency than the children. Both groups, however, showed a learning effect, such that in general, later Day 1 trials and Day 2 trials were shorter in duration and more consistent in coordination patterns than Day 1 early trials. Phonemic complexity of the nonwords had a profound effect on both the behavioral and speech motor aspects of performance. The children showed marked learning effects on all nonwords that they could produce accurately, while adults’ performance improved only when challenged by the more complex nonword stimuli in the set. The findings point to a critical role for speech motor processes within models of nonword repetition and suggest that young adults, similar to children, show short‐ and longer‐term improvements in coordinative consistency with repeated production of complex nonwords. There is also a clear developmental change in nonword production performance, such that less complex novel sequences elicit changes in speech motor performance in children, but not in adults.     

Sex differences in language first appear in gesture

Children differ in how quickly they reach linguistic milestones. Boys typically produce their first multi‐word sentences later than girls do. We ask here whether there are sex differences in children’s gestures that precede, and presage, these sex differences in speech. To explore this question, we observed 22 girls and 18 boys every 4 months as they progressed from one‐word speech to multi‐word speech. We found that boys not only produced speech + speech (S+S) combinations (‘drink juice’) 3 months later than girls, but they also produced gesture + speech (G+S) combinations expressing the same types of semantic relations (‘eat’ + point at cookie) 3 months later than girls. Because G+S combinations are produced earlier than S+S combinations, children’s gestures provide the first sign that boys are likely to lag behind girls in the onset of sentence constructions.     

Online usage of theory of mind continues to develop in late adolescence

The development of theory of mind use was investigated by giving a computerized task to 177 female participants divided into five age groups: Child I (7.3–9.7 years); Child II (9.8–11.4); Adolescent I (11.5–13.9); Adolescent II (14.0–17.7); Adults (19.1–27.5). Participants viewed a set of shelves containing objects, which they were instructed to move by a ‘director’ who could see some but not all of the objects. Correct interpretation of critical instructions required participants to use the director’s perspective and only move objects that the director could see. In a control condition, participants were asked to ignore objects in slots with a grey background. Accuracy improved similarly in both conditions between Child I and Adolescent II. However, while performance of the Adolescent II and Adult groups did not differ in the control condition, the Adolescent II group made more errors than the adults in the experimental condition. These results suggest that theory of mind use improves between late adolescence and adulthood. Thus, while theory of mind tasks are passed by age 4, these data indicate that the interaction between theory of mind and executive functions continues to develop in late adolescence.
