Anticipatory reconfiguration elicited by fully and partially informative cues that validly predict a switch in task

Task-switching studies show no behavioral benefit of partially informative cues. However, ERP evidence of an early cue-locked positivity elicited by both fully and partially informative cues suggests that both cues trigger an anticipatory component of task set reconfiguration (Nicholson, Karayanidis, Davies, & Michie, 2006). We examined this apparent discrepancy using a cued-trials task-switching paradigm with three tasks. The ERP finding of an early cue-locked positivity was replicated for both switch-to cues, which validly predicted an upcoming switch trial and specified the new task set, and switch-away cues, which validly predicted an upcoming switch trial but not the new task set. This component was not elicited by a noninformative cue that did not specify whether the task would switch or repeat. Switch-away cues resulted in more accurate but not faster responding than did noninformative cues. Modeling of decision processes confirmed a speed-accuracy trade-off between these conditions and a preparation benefit for both switch-to and switch-away cues. These results indicate that both fully and partially informative cues elicit an early anticipatory component of task set reconfiguration that is reflected in the early cue-locked positivity. We argue that the pattern of results is most consistent with a task set inhibition account of this early anticipatory component of task set reconfiguration.     

Voices of Outreach: The Construction of Identity and Maintenance of Social Ties Among Chabad-Lubavitch Emissaries

Fundamentalists typically avoid influences from the outside world and form intense social bonds with members of their own group. Yet, active fundamentalists must create relationships with the objects of their missionary action, the Other. In this article I address the connections between the cultural practice of missionary work and the formation and maintenance of social ties among ultra-Orthodox Jewish missionaries belonging to the fundamentalist Hasidic sect Chabad-Lubavitch. These missionaries attempt to bring Jews to the beliefs and practices of Chabad by hosting Jews at Sabbath meals. This missionary act is an utterance that "speaks" with multiple voices, indexing the missionaries as both friendly members of their local Jewish community and ideal Lubavitchers. Through these meals, the missionaries engage not only the local Jews but also other Lubavitchers in dialogue, constructing a community that transcends face-to-face interaction.     

What creates the dilemma in ethical dilemmas? Examples from psychological practice

Twenty psychologists were interviewed about an ethical dilemma that they had found to be particularly difficult to resolve. In just under half of the cases the dilemma involved a perceived conflict of ethical principles (e.g., the welfare of the consumer vs. the right to privacy). In the other cases, the psychologists were prevented from following an ethically prescribed course of action by some nonethical consideration such as contractual obligation, legal requirement, or the demands of an employer. We discuss the implications of these two sorts of dilemmas for psychological practice and make some suggestions for proactive approaches to ethical problem solving.     

Gestural development,dual-directional signaling,and the transition to words

This paper describes the emergence and development of three object-related gestures: pointing, extending objects, and open-handed reaching, in four first-born infants from 9 to 18 months during natural interactions with their mothers. It examines the changing characteristics of the gestures and the acquisition of conventional words in accompaniment. Furthermore, it investigates the role that the capacity for dual-directional signaling, sending simultaneously two coordinated but divergently directed nonverbal signals of gesture and gaze, may play in this transition. Analysis revealed that dual-directional signaling appeared concurrently across gestures. In addition, dual-directional signaling was employed in a socially adjusted manner, more with pointing, especially spontaneous pointing when the mothers' attention could not be assumed. Verbal accompaniments appeared with gestures only when the children had mastered dual-directional signaling. Then words emerged approximately simultaneously with more than one kind of gesture.     

Developmental changes in apportionment of study time among items in a multitrial free recall task

First grade, third grade, and college Ss attempted to memorize a single set of items over the course of 5 trials, each trial consisting of a 45-sec study period followed by a free recall test. On all trials but the first, S was allowed to have available during his study period only half of the total set of items, but was free to select whichever items he wished to include in this half. Third grade and college Ss were significantly more prone than first grade Ss to select for study items not recalled in the immediately preceding recall test. The results suggest that the strategy of deliberately concentrating one's study activities on the less well mastered segments of materials to be learned, like other elementary memory strategies (e.g., rote rehearsal), cannot automatically be assumed to be part of a young child's repertoire of learning techniques.     

Personal reflections: barriers and strategies in increasing diversity in psychology

In this article, six faculty and students of color who participated in a panel discussion at a symposium during the National Multicultural Conference and Summit of 2003 talk about the barriers they encountered and continue to encounter in their graduate training and places of employment. They also discuss strategies they found to be effective, enhancing, and positive and suggest other possibilities. The contributors describe their relationships with dominant-group and minority peers and talk about how issues of social class, disability, and sexual orientation as well as color have been part of their experience.     

Individual differences and cross-situational consistency of dyadic social behavior

A new theoretical analysis of individual differences and cross-situational consistency of behavior is proposed. The authors hypothesized that the social behavior of mice (Mus musculus) is determined by individual differences among animals in behavior emitted (i.e., actor effects), in behavior elicited from social partners (partner effects), and by unique responses of one animal to another (relationship effects). Each effect represents a distinct facet of individual differences with different psychological meaning; likewise, the cross-situational consistency of each effect has a distinct psychological meaning. Individual differences in behavior emitted were observed, and these actor effects were consistent longitudinally. Individual differences in behavior elicited from social partners were observed, and these partner effects were also consistent longitudinally. Unique responses to specific social partners also determined behavior but were inconsistent longitudinally. The theoretical importance of reconceptualizing the concepts of individual differences and cross-situational consistency in behavior is discussed. ((c) 2005 APA, all rights reserved).     

Leadership experiences of bicultural business leaders: An interpretative phenomenological analysis

Using the lens of interpretative phenomenological analysis, this study explored the leadership experiences of bicultural business leaders in the Philippines. Semistructured interviews were conducted among 16 leaders in family-owned, small and medium-sized enterprises in the Philippines who are ethnically Chinese and have Filipino nationality. Findings focused on salient expressions of biculturalism in leadership, bicultural leadership challenges, and advantages. Most of the participants experienced fluidity in their expressions of Filipino and Chinese identities and how these manifest in the workplace. Challenges shared pertain to generational factors as participants assumed leadership roles through kinship, as well as relational challenges reflective of cultural nuances. The leaders view their being bicultural as having the “best of both worlds” as they have greater access to cultural information and a more holistic view of which values and norms to use in their leadership roles and in various social interactions. Fluency in communicating in Chinese and Filipino was perceived to enable effective interactions and facilitate trust building with their customers, employees, and suppliers. Implications focused on the need to consider biculturalism in leadership development programmes in educational institutions and organizations, especially with increasing bi/multiculturalism in workplaces.
