控制感剥夺激发状态毅力：趋近动机的中介作用

采用概念判断任务,通过两个递进式实验探索控制感剥夺对状态毅力的影响并考察趋近动机在其中的作用。实验1主观报告结果显示：短时条件下,控制感剥夺组的状态毅力显著高于控制感维持组,尤其表现在努力持续性维度;长时条件下,两组差异不显著。实验2在此基础上加入行为指标结果显示：短时控制感剥夺通过高趋近动机对状态毅力产生影响。结果表明毅力是可塑的,突出表现在努力持续性上,该效应出现在个体经历短时控制感剥夺后。     

State‐Trace Analysis: Dissociable Processes in a Connectionist Network?

Some argue the common practice of inferring multiple processes or systems from a dissociation is flawed (Dunn, 2003). One proposed solution is state‐trace analysis (Bamber, 1979), which involves plotting, across two or more conditions of interest, performance measured by either two dependent variables, or two conditions of the same dependent measure. The resulting analysis is considered to provide evidence that either (a) a single process underlies performance (one function is produced) or (b) there is evidence for more than one process (more than one function is produced). This article reports simulations using the simple recurrent network (SRN; Elman, 1990) in which changes to the learning rate produced state‐trace plots with multiple functions. We also report simulations using a single‐layer error‐correcting network that generate plots with a single function. We argue that the presence of different functions on a state‐trace plot does not necessarily support a dual‐system account, at least as typically defined (e.g. two separate autonomous systems competing to control responding); it can also indicate variation in a single parameter within theories generally considered to be single‐system accounts.     

Culture and state boredom: A comparison between European Canadians and Chinese

The primary goal of the present research was to examine cross-cultural validity of the Multidimensional State Boredom Scale (MSBS) by comparing a European Canadian sample and a Chinese sample. The secondary goal was to explore cross-cultural differences in the actual experience of boredom between European Canadian and Chinese participants when they completed a psychological survey. After establishing cross-cultural validity of the MSBS by eliminating items that functioned differentially across the two cultural groups, we found that European Canadians scored higher on the MSBS than did Chinese. Results are consistent with the literature on cultural differences in ideal affect, such that European North Americans (vs. East Asians) tend to value high-arousal positive affects (e.g., excitement) more, and low-arousal positive affect less (Tsai, Knutson, & Fung, 2006).     

The effects of trait and state anxiety on attention to emotional images: An eye-tracking study

Attentional biases for threatening stimuli have been implicated in the development of anxiety disorders. However, little is known about the relative influences of trait and state anxiety on attentional biases. This study examined the effects of trait and state anxiety on attention to emotional images. Low, mid, and high trait anxious participants completed two trial blocks of an eye-tracking task. Participants viewed image pairs consisting of one emotional (threatening or positive) and one neutral image while their eye movements were recorded. Between trial blocks, participants underwent an anxiety induction. Primary analyses examined the effects of trait and state anxiety on the proportion of viewing time on emotional versus neutral images. State anxiety was associated with increased attention to threatening images for participants, regardless of trait anxiety. Furthermore, when in a state of anxiety, relative to a baseline condition, durations of initial gaze and average fixation were longer on threat versus neutral images. These findings were specific to the threatening images; no anxiety-related differences in attention were found with the positive images. The implications of these results for future research, models of anxiety-related information processing, and clinical interventions for anxiety are discussed.     

Samoa and the Christian state ideal

This article explores the notion of a Christian state in the context of the South Pacific island nation of Samoa. Samoa is not a Christian state in the constitutional de jure sense. There is no formal entrenchment of establishment of Christianity as the official religion. But it is a de facto Christian state in that the substance of its laws reflects Christian beliefs. The article also considers whether it is a Christian nation. In many cultural and sociological senses it is. In terms of Christian practice however, an affirmative verdict is highly doubtful. Finally, the article suggests that asking the Christian nation question might be misplaced, for no nation can be a ‘chosen’, covenantal nation, à la Israel, in the New Testament era.     

Sex task and processing strategy effects in hemispheric alpha asymmetries for the recall and recognition of arousal words: results from perceptual and motor tasks in males and females

Hemispheric alpha asymmetries of males and females were observed during perceptual and motor tasks requiring recall and recognition of words controlled for level of arousal (positive, negative, and neutral). Verbal reports of individual processing strategy were collected and analyzed relative to hemispheric alpha ratios. Results showed greater alpha suppression in the left relative to right hemisphere for recall as compared to recognition tasks and for word presentation when contrasted with motor conditions. High positive correlations were found between narrative report of processing strategy and hemispheric alpha data. A separate analysis revealed that seven subjects identified as highly analytic processors showed greater alpha suppression in the left relative to right hemisphere across tasks, conditions, and stimuli than did seven highly visual processors who, in contrast, demonstrated greater right hemispheric alpha suppression. Task difficulty and individual differences in processing style that modify cerebral laterality effects are discussed.     

Sex stereotypes in occupational choice: The case for college women

The choice of a male dominated occupation rather than a traditionally feminine one is the single occupational variable which meaningfully divides a class of women who were studied intensively over the 4 yr of college. Women who choose occupations which employ largely men differ predictably from women who select feminine occupations in terms of familial influence, work values, work experience, role model influence and some collegiate activities. The two groups do not differ appreciably in sociability experiences or in relationships with parents, so it cannot be argued that the work plans of the pioneer women stem from social isolation, rejection, or lack of appropriate feminine socialization.     

Motivation to manage among women: Studies of college students

Studies were conducted with samples of students from four different universities to determine if male-female differences in motivation to manage existed. Although differences were not found among students majoring in the field of education, females in business administration and the liberal arts did prove to have lower managerial motivation scores than the comparable male samples. These findings are discussed in terms of their relationships to sex discrimination, prospective managerial talent shortages and the vocational guidance of female college students.     

Dry-bed training: rapid elimination of childhood enuresis

Enuresis has been treated with moderate effectiveness by the urine-alarm method which requires many weeks of training. The present procedure used a urine-alarm apparatus but added such features as training in inhibiting urination, positive reinforcement for correct urinations, training in rapid awakening, increased fluid intake, increased social motivation to be nonenuretic, self-correction of accidents, and practice in toileting. After one all-night training session, the 24 enuretic children averaged only two bedwettings before achieving fourteen consecutive dry nights and had no major relapses. Little or no reduction in bedwetting occurred within the first two weeks for matched-control enuretics who were given the standard urine-alarm training. The results of a control-procedure showed that the new procedure did not involve Pavlovian conditioning. The new method appears to be a more rapid, effective and different type of treatment for enuresis.
