The mnemonic effect of speech gestures: Pantomimic and non-pantomimic gestures compared

Abstract

A video-taped model presented subjects with sets of sentences to be free-recalled. under three presentation conditions: (1) accompanied by pantomimic gestures; (2) accompanied by non-pantomimic gestures; and (3) no gestures present. When the sentences formed a narrative, the gestures did not affect recall. When the sentences were unconnected, recall was higher for the gestured than for tbe non-gestured sentences. The pantomimic and non-pantomimic gestures showed about the same mnemonic effect. The subjects were given a second test, either recall-cued by the gestures, or else free recall of the gestured Sentences only. The pantomimic conditions were superior to the non-pantomimic conditions in both these tests. Possible explanations for the mnemonic effects of the gestures are discussed.     

Age differences in proactive interference in verbal and visuospatial working memory

Abstract

In a free recall situation, subjects can predict, with some degree of accuracy, which words they will subsequently recall. This study focused on the question of why subjects often recall words to which they assign low prediction ratings. This problem was approached by comparing the properties of recall-not-predicted (RNP) and recall-predicted (RP) words which appeared in subjects' recall protocols. No differences were found between the two types of items (RNP and RP) in retrieval monitoring. The two types of items were differentiated by whether subjects could recollect the actual occurrence of the recalled items in the study list (“remember” responses) or not (“know” responses). Furthermore, the recall of RNP items, but not RP items, was improved by retrieval prompts. These results were taken to support the position that weakly encoded items may be recalled if they encounter a highly favourable retrieval environment, not anticipated by subjects during study.     

Occupational stress,psychological burnout and anxiety

Abstract

For many decades, the stress process was described primarily in terms of negative emotions. However, robust evidence that positive emotions co-occurred with negative emotions during intensely stressful situations suggested the need to consider the possible roles of positive emotions in the stress process. About 10 years ago, these possibilities were incorporated into a revision of stress and coping theory (Folkman, 1997). This article summarizes the research reported during the intervening 10 years that pertains to the revised model. Evidence has accumulated regarding the co-occurrence of positive and negative emotions during stressful periods; the restorative function of positive emotions with respect to physiological, psychological, and social coping resources; and the kinds of coping processes that generate positive emotions including benefit finding and reminding, adaptive goal processes, reordering priorities, and infusing ordinary events with positive meaning. Overall, the evidence supports the propositions set forth in the revised model. Contrary to earlier tendencies to dismiss positive emotions, the evidence indicates they have important functions in the stress process and are related to coping processes that are distinct from those that regulate distress. Including positive emotions in future studies will help address an imbalance between research and clinical practice due to decades of nearly exclusive concern with the negative emotions.     

On the Failure to Detect Changes in Scenes Across Brief Interruptions

When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: The changes become extremely difficult to notice, even when they are large, presented repeatedly, and the observer expects them to occur (Rensink, O'Regan, & Clark, 1997). To determine the mechanisms behind this induced “change blindness”, four experiments examine its dependence on initial preview and on the nature of the interruptions used. Results support the proposal that representations at the early stages of visual processing are inherently volatile, and that focused attention is needed to stabilize them sufficiently to support the perception of change.     

Combining Methodologies in the Construct Validation Process: An Empirical Illustration

Confirmatory Factor Analysis (CFA) has received considerable support as a methodology for assessing construct validity. As with other methodologies, however, numerous problems can be encountered when using CFA to assess construct validity. Given the limitations of the CFA, Multitrait-Multimethod (MTMM), and analysis of variance (ANOVA) methodologies, a set of guidelines was developed. The guidelines recommend that the characteristics of the data set be used to determine how the three alternative construct validation methodologies can be used in combination. Examples from the research literature are discussed in order to demonstrate the application of these guidelines.     

Relative Importance and Utility of Positive Worker States: A Review and Empirical Examination

Our purpose was to identity the unique contribution, relative importance, and utility of positive worker states. Using Luthans et al.'s (2007) five positive organizational behavior criteria, a variety of positive worker states were reviewed and then empirically tested to establish if they met these criteria. Data were collected from 724 restaurant employees. Positive worker states included: job involvement, perceived organizational support, engagement, and vigor. Criteria were self-reported performance, customer service, turnover intention, satisfaction, and quality of life. Our review indicated consistency between predictor adequacy of meeting the criteria and their empirical relationship with key outcomes. This research found the positive worker states to be independent constructs that had differential effects depending on the focused outcome. Regression and relative weights analyses showed involvement was a weak predictor of outcomes, while perceived organizational support was the most consistent predictor. Vigor was most useful when predicting job performance. Quality of life was poorly explained.     

Attitude Transference and Deviant Behavior: A Comparative Study in Japan and the United States

Attitude transference is the term that has come to be used to refer to a key process by which one's personal attitudes approving or disapproving of certain behavior reflect those of his or her primary groups and in turn affect his or her conforming or deviant behavior. Cross-cultural comparisons on this and other issues afforded by previous studies, however, have been limited primarily to examining findings that have used different samples and instructions. Drawing on previous literature on cultural variability in individualism, the present study directly tests the hypotheses that although attitude transference operates similarly across cultures, the effects of parental and peer attitudes toward deviance on one's own attitudes should be weaker and stronger, respectively, in Japan compared to the United States. The analysis of identical survey data from college students in the two societies provides mixed support for the hypotheses.     

Cessation of alcohol and drug use among adolescents: A social learning model

This investigation tests the ability of Akers’ (1977) social learning theory of deviance to account for the cessation of alcohol or drug use among adolescents. For each of five substances, two‐group discriminant function analyses showed that social learning variables were successful in discriminating adolescents who ceased using from their counterparts who continued to use. Peer associations were generally most discriminating with normative definitions and social rewards or punishments also contributing to differentiation. Positive or negative effects of the substances as well as imitation bore little relationship to cessation. Social learning theory was as explanatory for stronger drugs as it was for alcohol and marijuana. Policy and program implications are suggested.     

Support for Resistance Among Iraqi Students: An Exploratory Study

This study examines predictors of expressed support for resistance to U.S.-led forces in Iraq among a sample of 130 university students in Baghdad. Based on a review of the literature and common discourse, personality, clash of civilization and social-psychological variables are tested as likely predictors of support for resistance. Data were collected in March 2004 during a period of relative political stability and optimism. Only social-psychological variables significantly predicted support. In particular, national identity, perceived procedural injustice, and higher life satisfaction prior to the U.S.-led invasion were significant predictors. Findings are discussed in relation to media and academic accounts explaining political violence in the current conflict.     

IDENTITY AND DISTINCTION IN SPINOZA'S ETHICS1

Abstract: In Ethics 1p5, Spinoza asserts that “In Nature there cannot be two or more substances of the same nature or attribute”. This claim serves as a crucial premise in Spinoza's argument for substance monism, yet Spinoza's demonstration of the 1p5 claim is surprisingly brief and appears to have obvious difficulties. This paper answers the principle difficulties that have been raised in response to Spinoza's argument for 1p5. The key to understanding the 1p5 argument lies in a proper understanding of the substance‐attribute relationship and the principles of metaphysical individuation that Spinoza accepts.
