Putting action in perspective

Embodied approaches to cognition propose that our own actions influence our understanding of the world. Do other people's actions also have this influence? The present studies show that perceiving another person's actions changes the way people think about objects in a scene. In Study 1, participants viewed a photograph and answered a question about the location of one object relative to another. The question either did or did not call attention to an action being performed in the scene. Studies 2 and 3 focused on whether depicting an action in a scene influenced perspective choice. Across all studies, drawing attention to action, whether verbally or pictorially, led observers to encode object locations from the actor's spatial perspective. Study 4 demonstrated that the tendency to adopt the actor's perspective might be mediated by motor experience.     

Behaviorally at-risk African American students:The importance of student-teacher relationships for student outcomes

The purpose of this exploratory study was to examine the associations between the student-teacher relationship and outcomes for African American students who were behaviorally at-risk for referral to special education. Students were identified by their teachers as having behavior problems. Participants were 44 students and 25 teachers from two suburban and three urban elementary schools in a mid-western state. A multi-rater, multi-method approach was used. As teacher-reports of student-teacher relationship quality increased, there were also increases in positive social, behavioral, and engagement outcomes for students. Similarly, as student-reports of student-teacher relationship quality increased, there were increases in positive behavioral, engagement, and academic outcomes. Additional analyses of dyadic relationship patterns showed that as the relationship pattern improved (moving from negative concordance to discordance to positive concordance), there were increases in positive social, behavioral, and engagement outcomes for students. Implications for school practice are discussed.     

Changing Perspective: Building Creative Mindsets

The search for new ideas often frustratingly cycles back to old ones, a phenomenon known as fixation. Recent research has shown ways to kick-start finding new uses for familiar objects, a prototypical creativity task: wandering in the mind or the world or working on a messy desk. Those techniques seem to succeed by helping break fixation, but do not guide the search for new ideas. The perspective-taking or human-centric or empathic mindset championed by many in HCI and in design firms does provide a search strategy. We compared the mind-wandering mindset to a perspective-taking mindset, the latter priming thinking of ways that people in different roles (gardener, artist, etc.) might use the objects. In two studies, the Perspective-Taking mindset yielded more ideas and more original ideas than Mind-Wandering, which did not differ from a No-Mindset control. Original ideas came late, rewarding persistence. The perspective-taking mindset is productive for problem-solving, forecasting, and social interactions as well as innovation.     

The language of online leadership: gender and youth engagement on the internet

This study examines the JUNIOR SUMMIT online community, which consisted of 3,062 adolescents representing 139 countries, varying SES, and a range of experience with computers. The online forum culminated in the election of 100 delegates. By analyzing the messages posted before results of the election were announced, we explore whether language use predicts who was elected as a leader, as well as gender differences in leadership style. Results indicate that the young online leaders do not adhere to adult leadership styles of contributing many ideas, sticking to task, and using powerful language. On the contrary, while the young people elected as delegates do contribute more, their linguistic style is likely to keep the goals and needs of the group as central--by referring to the group rather than to themselves, and by synthesizing the posts of others rather than solely contributing their own ideas. Furthermore, both boy and girl leaders follow this pattern of interpersonal language use. These results reassure us that young people can be civically engaged and community minded, while indicating that these concepts themselves may change through contact with the next generation.     

Making sense of abstract events: Building event schemas

Everyday events, such as making a bed, can be segmented hierarchically, with the coarse level characterized by changes in the actor’s goals and the fine level by subgoals (Zacks, Tversky, &; Iyer, 2001). Does hierarchical event perception depend on knowledge of actors’ intentions? This question was addressed by asking participants to segment films of abstract, schematic events. Films were novel or familiarized, viewed forward or backward, and simultaneously described or not. The participants interpreted familiar films as more intentional than novel films and forward films as more intentional than backward films. Regardless of experience and film direction, however, the participants identified similar event boundaries and organized them hierarchically. An analysis of the movements in each frame revealed that event segments corresponded to bursts of change in movement features, with greater bursts for coarse than for fine units. Perceiving event structure appears to enable event schemas, rather than resulting from them.     

Hierarchical encoding of behavior: translating perception into action

People encode goal-directed behaviors, such as assembling an object, by segmenting them into discrete actions, organized as goal-subgoal hierarchies. Does hierarchical encoding contribute to observational learning? Participants in 3 experiments segmented an object assembly task into coarse and fine units of action and later performed it themselves. Hierarchical encoding, measured by segmentation patterns, correlated with more accurate and more hierarchically structured performance of the later assembly task. Furthermore, hierarchical encoding increased when participants (a) segmented coarse units first, (b) explicitly looked for hierarchical structure, and (c) described actions while segmenting them. Improving hierarchical encoding always led to improvements in learning, as well as a surprising shift toward encoding and executing actions from the actor's spatial perspective instead of the participants' own. Hierarchical encoding facilitates observational learning by organizing perceived actions into a representation that can serve as an action plan.     

A Review of Diagnostic Techniques in the Differential Diagnosis of Epileptic and Nonepileptic Seizures

The diagnosis of psychogenic nonepileptic seizures (PNES) is complex. Long-term electroencephalogram monitoring with video recording (video EEG) is the most common method of differential diagnosis of epilepsy and PNES. However, video EEG is complex, costly, and unavailable in some areas. Thus, alternative diagnostic techniques have been studied in the search for a diagnostic method that is as accurate as video EEG, but more cost effective, convenient, and readily available. This paper reviews the literature regarding possible diagnostic alternatives and organizes findings into 7 areas of study: demographic and medical history variables, seizure semiology, provocative testing, prolactin levels, single photon emission computed tomography, psychological testing, and neuropsychological testing. For each area, the literature is summarized, and conclusions about the accuracy of the technique as a diagnostic tool are drawn. Overall, it appears unlikely that any of the reviewed alternative techniques will replace video EEG monitoring; rather they may be more successful as complementary diagnostic tools. An important focus for further investigations involves combinations of diagnostic techniques for the differential diagnosis of epilepsy and PNES.     

Spinning the stories of our lives

The way people talk about past events can affect the way they remember them (Tversky & Marsh, 2000). The current research explores how people naturally talk about events from their own lives. Participants recorded what, when, and how they told others about events from their lives. In general, participants talked about recent emotional events, and told them primarily to peers in order to convey facts and/or to entertain. Not all distorted retellings were regarded as ‘inaccurate.’ Participants labeled 61% of their retellings as distorted (containing exaggerations, omissions, minimizations, or additions) but only 42% of their retellings as inaccurate. Social context shaped the stories people told: they changed stories for different audiences; they exaggerated to entertain and simplified to inform. People construct stories as they retrieve and use memories in a social context. Copyright © 2004 John Wiley & Sons, Ltd.
