A simple procedure for accurately manipulating face-voice synchrony when dubbing speech onto videotape

A system is described involving an audio-video tape recorder, a control device, and a delay timer that dubs speech sounds onto prerecorded lip movements on videotape. Accuracy of synchrony or measured asynchrony between the sound and lip movements is a few milliseconds.     

The interaction of social skill and organizational support on job performance

The present study examined the moderating effect of perceived organizational support (POS) on the relationship between social skill and supervisor-rated job performance. On the basis of regulatory and activation models of behavior, the authors argue that low-POS environments activate social skill because they reflect situations in which interpersonal acuity is required to demonstrate effective job performance. Accordingly, the authors hypothesize that social skill is more strongly related to performance among workers reporting low rather than high levels of organizational support. Results of hierarchical moderated multiple regression analyses on data gathered from 2 samples support the hypothesis. These results suggest that the relevance of social skill to job performance may be dependent on contextual cues. Implications for substantive research, strengths and limitations, and directions for future research are offered.     

The role of age in the perceptions of politics--job performance relationship: a three-study constructive replication

This research examined the interaction of organizational politics perceptions and employee age on job performance in 3 studies. On the basis of conservation of resources theory, the authors predicted that perceptions of politics would demonstrate their most detrimental effects on job performance for older workers. Results across the 3 studies provided strong support for the hypothesis that increases in politics perceptions are associated with decreases in job performance for older employees and that perceptions of politics do not affect younger employees' performance. Implications of these results, strengths and limitations, and directions for future research are discussed.     

Quality circles in the United States: a conceptual reevaluation

Faced with industrial decline, American managers have begun searching for strategies for increasing productivity. Recent attention has focused on Japanese management practices, particularly on quality circles (QCs). Drawing upon social science research, this article evaluates the assumptions behind QCs implemented in the United States. The authors present a conceptual analysis that indicates possible reasons for the differing rates of success for QCs in Japan and the U.S. The article also makes suggestions for the effective implementation of American QCs.     

The pen is mightier than the word: Object priming of evaluative standards

Because red pens are closely associated with error‐marking and poor performance, the use of red pens when correcting student work can activate these concepts. People using red pens to complete a word‐stem task completed more words related to errors and poor performance than did people using black pens (Study 1), suggesting relatively greater accessibility of these concepts. Moreover, people using red pens to correct essays marked more errors (Study 2) and awarded lower grades (Study 3) than people using blue pens. Thus, despite teachers' efforts to free themselves from extraneous influences when grading, the very act of picking up a red pen can bias their evaluations.

G(o) activation is required for both appetitive and aversive memory acquisition in Drosophila

Heterotrimeric G(o) is an abundant brain protein required for negatively reinforced short-term associative olfactory memory in Drosophila. G(o) is the only known substrate of the S1 subunit of pertussis toxin (PTX) in fly, and acute expression of PTX within the mushroom body neurons (MB) induces a reversible deficit in associative olfactory memory. We demonstrate here that the induction of PTX within the α/β and γ lobe MB neurons leads to impaired memory acquisition without affecting memory stability. The induction of PTX within these MB neurons also leads to a significant defect in an optimized positively reinforced short-term memory paradigm; however, this PTX-induced learning deficit is noticeably less severe than found with the negatively reinforced paradigm. Both negatively and positively reinforced memory phenotypes are rescued by the constitutive expression of G(o)α transgenes bearing the Cys(351)Ile mutation. Since this mutation renders the G(o) molecule insensitive to PTX, the results isolate the effect of PTX on both forms of olfactory associative learning to the inhibition of the G(o) activation.     

Frequency of Interpersonal Trauma Types,Avoidant Attachment,Self-Compassion,and Interpersonal Competence: A Model of Persisting Posttraumatic Symptoms

Given limited knowledge about how psychosocial factors interact to modulate posttraumatic stress symptoms, this study evaluated an integrative model proposing that experiencing more interpersonal trauma types (e.g., abuse, assault, rape, etc.) leads to greater avoidant attachment and lower self-compassion, which limits the development and use of effective interpersonal skills. In turn, lower levels of self-compassion and interpersonal competence perpetuate posttraumatic symptoms. Anonymous trauma-experienced adults (n = 132) completed self-report measures in an online study hyperlinked on trauma support websites. Data were subjected to confirmatory factor analysis and structural equation modeling, which provided support for the hypothesized model. Specifically, higher frequency of interpersonal trauma types experienced was linked to higher avoidant attachment and lower self-compassion, which in turn were associated with lower interpersonal competence, which correlated with greater posttraumatic stress symptoms. Although cross-sectional data cannot address directionality of associations, this study’s findings emphasize the potential utility of future longitudinal research designed to examine possible causal relationships among these specific psychosocial factors. For example, study findings suggest that those who experience more types of interpersonal trauma and who are characterized by avoidant attachment and lower self-compassion and interpersonal competence may be the most susceptible to experiencing severe posttraumatic symptoms. However, findings also suggest that efforts to increase self-compassion and interpersonal skills may help reduce symptoms.     

Patients with bipolar disorder show a selective deficit in the episodic simulation of future events

A substantial body of evidence suggests that autobiographical recollection and simulation of future happenings activate a shared neural network. Many of the neural regions implicated in this network are affected in patients with bipolar disorder (BD), showing altered metabolic functioning and/or structural volume abnormalities. Studies of autobiographical recall in BD reveal overgeneralization, where autobiographical memory comprises primarily factual or repeated information as opposed to details specific in time and in place and definitive of re-experiencing. To date, no study has examined whether these deficits extend to future event simulation. We examined the ability of patients with BD and controls to imagine positive, negative and neutral future events using a modified version of the Autobiographical Interview (Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002) that allowed for separation of episodic and non-episodic details. Patients were selectively impaired in imagining future positive, negative, and neutral episodic details; simulation of non-episodic details was equivalent across groups.     

An Ecological Process Model of Systems Change

In June 2007 the American Journal of Community Psychology published a special issue focused on theories, methods and interventions for systems change which included calls from the editors and authors for theoretical advancement in this field. We propose a conceptual model of systems change that integrates familiar and fundamental community psychology principles (succession, interdependence, cycling of resources, adaptation) and accentuates a process orientation. To situate our framework we offer a definition of systems change and a brief review of the ecological perspective and principles. The Ecological Process Model of Systems Change is depicted, described and applied to a case example of policy driven systems level change in publicly funded social programs. We conclude by identifying salient implications for thinking and action which flow from the Model.
