Decreasing household television time: a pilot study of a combined behavioral and environmental intervention

Excessive TV viewing is associated with weight gain across the lifespan; thus developing strategies to decrease household viewing time may be an effective obesity prevention approach. This pilot study (n = 6 families) examined the feasibility and short‐term impact of a 2‐pronged environmental plus behavioral approach designed to reduce TV time in the entire family. The environmental manipulation involved placing TV Allowances (programmed to turn off power after family members had watched 75% of their baseline hours) on all TVs in the home. A kit with behavioral strategies for reducing TV time was also sent to the home each week and family members self‐monitored viewing time. Viewing was objectively assessed with the TV Allowances at baseline and at 8 weeks. A significant decrease in objectively measured TV viewing hours was observed, t(5) = 3.1, p = 0.03, 29.8 ± 10.3 versus 14.9 ± 6.0 h (equivalent of decreasing from 7.5 to 3.7 h per day). Fifty percent of families reduced their viewing time by ≥50%. The acceptability of the intervention was high, with 100% of families reporting they would recommend the TV Allowances to others. Further research is needed to test the long‐term efficacy of the program and its impact on weight. Copyright © 2006 John Wiley & Sons, Ltd.     

He Lin and German Philosophy in the Zhanguoce School: An Idealist Philosopher on History and Cultural Reform

The Zhanguoce School emerged in 1940 and actively responded to the crisis caused by the Sino-Japanese War. The cultural morphology of Oswald Spengler (1880–1936) inspired most of the leading Zhanguoce scholars to reflect on the culture, history, and status quo of China. They believed that China was suffering from a total war with world superpowers and that it was in a new Warring States epoch; they thus advocated radical cultural reform as a necessary condition for victory and invoked Nietzschean philosophy to champion heroism and power. However, He Lin 賀麟 (1902–92), a philosopher in this school, looked to Georg Wilhelm Friedrich Hegel (1770–1831) and Johann Gottlieb Fichte (1762–1814) for different theories of cultural reform and history. This article examines He’s integration of the philosophies of Hegel and Fichte into his cultural and historical thought. Based on the Hegelian notion of Spirit, He rethought the nature of culture and the relationship between Chinese and Western cultures; he also interpreted history by comparing the historical theories of Hegel and Wang Fuzhi 王夫之 (1619–92). Furthermore, He investigated individual realization with reference to Fichte and repudiated radical heroism.     

Attributionally more complex people show less punitiveness and racism

Based on past findings that attributionally more complex people make less fundamental attribution error, it was hypothesized that they would show less punitiveness and racism. In a study of 102 undergraduates, this hypothesis received robust support. The effect of attributional complexity was significant in two different punitiveness measures, a rehabilitation support measure, and two different racism measures. Also, this effect still held when demographic variables, crime victimization history, and need for cognition were statistically controlled. Moreover, attributional complexity mediated the effect of need for cognition and gender on punitiveness and racism. Theoretical implications are discussed.     

Impact of background characteristics and gender–role attitudes on Chinese perceptions of selection criteria in employment

A random sample of 699 (327 men and 372 women) currently employed Chinese subjects participated in a study that examined their perceptions of common selection criteria in employment. Results of factor analysis showed that various selection criteria could be grouped under four underlying factors. In general, participants rated the Psychological Attribute factor as the most important criterion, followed closely by the Experience and Skill factor, and viewed the Physical Attribute and Demographic factors as the least important. Results of hierarchical regression analyses showed that participants'gender–role attitudes, especially those towards men's and women's roles in education, marriage and social interactions, were the most salient predictors of their perceptions towards the selection criteria. This remained true even after controlling for participants' background characteristics. Participants' gender, age and educational attainment were also predictive of their appraisal of various selection criteria in employment.     

Effects of initial choices in the prisoner's dilemma

In the two‐person prisoner's dilemma game (PDG), there is considerable evidence that the tit‐for‐tat (TFT) strategy is most effective in inducing the other person to cooperate. One of the important features of the TFT strategy is that it cooperates on the first trial. We varied the initial choices of a simulated other, and tested the effects of (a) initial choices (cooperation or defection), and (b) persistence of initial choices: unilateral cooperation (or defection) on the first trial, first two trials, or first four trials. Results showed that a cooperative strategy—one that starts with cooperative choices—induced greater cooperation than a strategy that started with defections. The results of this study clearly show that (a) a cooperative strategy—one that initiates unilateral cooperation at the outset and then adopts a TFT strategy—is very effective in inducing subsequent cooperation from the other party, (b) the effectiveness of a cooperative strategy varies directly with the cooperative orientation of the other party (a cooperative strategy is more effective against a cooperative than a competitive person), and (c) initial cooperation is more effective if it is repeated more than once.

Non‐linear structural equation models with correlated continuous and discrete data

Structural equation models (SEMs) have been widely applied to examine interrelationships among latent and observed variables in social and psychological research. Motivated by the fact that correlated discrete variables are frequently encountered in practical applications, a non‐linear SEM that accommodates covariates, and mixed continuous, ordered, and unordered categorical variables is proposed. Maximum likelihood methods for estimation and model comparison are discussed. One real‐life data set about cardiovascular disease is used to illustrate the methodologies.     

Using the Hands to Identify Who Does What to Whom: Gesture and Speech Go Hand-in-Hand

In order to produce a coherent narrative, speakers must identify the characters in the tale so that listeners can figure out who is doing what to whom. This paper explores whether speakers use gesture, as well as speech, for this purpose. English speakers were shown vignettes of two stories and asked to retell the stories to an experimenter. Their speech and gestures were transcribed and coded for referent identification. A gesture was considered to identify a referent if it was produced in the same location as the previous gesture for that referent. We found that speakers frequently used gesture location to identify referents. Interestingly, however, they used gesture most often to identify referents that were also uniquely specified in speech. Lexical specificity in referential expressions in speech thus appears to go hand-in-hand with specification in referential expressions in gesture.     

The role of spatial integration in the perception of surface orientation with active touch

Vision research has shown that perception of line orientation, in the fovea area, improves with line length (Westheimer & Ley, 1997). This suggests that the visual system may use spatial integration to improve perception of orientation. In the present experiments, we investigated the role of spatial integration in the perception of surface orientation using kinesthetic and proprioceptive information from shoulder and elbow. With their left index fingers, participants actively explored virtual slanted surfaces of different lengths and orientations, and were asked to reproduce an orientation or discriminate between two orientations. Results showed that reproduction errors and discrimination thresholds improve with surface length. This suggests that the proprioceptive shoulder-elbow system may integrate redundant spatial information resulting from extended arm movements to improve orientation judgments.     

Measurement of recovery of function in the hemiparetic upper limb following stroke: A preliminary report

Although stroke poses major problems to the rehabilitation professions, little is understood about the processes of recovery of movement. We report here on research in progress aimed at documenting in detail the restitution of movement in the upper limb. The results presented are preliminary in nature since our main aim is to detail the methods by which we have embarked on this study.
