Opinion Change in Time of War

Two hundred ninety-five college students were tested to determine the effects of specified variables of self-appraisal and task appraisal on achievement, self-assessment of achievement, and expended effort. Primary results were as follows: (a) The academic self-concept was found to contribute significantly to achievement on a specific task. Partial correlation between the academic self-concept and task achievement with intelligence controlled was .39 (p ≤ .05). A nonsignificant partial correlation between task confidence and task achievement with intelligence controlled was .16 (considered high enough to warrant further study). (b) Approximately two-thirds of the variance in self-assessment of achievement was found to be due to one's perceived achievement on a specific task. The variables of self-appraisal (i. e., academic self-concept and self-confidence) were not found to affect self-assessment of achievement, nor the variables of task appraisal (i. e., task confidence and task interest). Expended effort appears to have had a small part in the total variance of self-assessment of achievement. (c) Expended effort was found to be significantly related to task interest, but variables of self-appraisal did not contribute significantly to expended effort.     

Effect of effort and deadlines on consumer product returns

While extant research has examined return policies as a combination of time and effort, we investigate both the independent and interactive impacts of time and effort on consumer decisions to return or retain products. We find that decreasing return deadlines can have the counterintuitive effect of increasing return rates under some conditions. Using construal level theory, we propose that perceived effort (both physical and cognitive) mediates the effect of return policy on return rates leading to suppressed returns. Further, when deadlines are framed as durations between store visits, overall product returns are exacerbated except when perceived effort is high.     

Work Personality,Work Engagement,and Academic Effort in a Group of College Students

The authors investigated the relationship between the variables of work engagement, developmental work personality, and academic effort in a sample of college students. This study provides evidence for the hypothesized positive relationship between academic effort, engagement, and work personality. When gender was controlled, the Work Tasks subscale of the Developmental Work Personality Scale ( Strauser & Keim, 2002 ) made the largest contribution to predicting academic effort. Engagement also made a significant contribution to the model. For men, work personality seems to be more relevant concerning academic effort, whereas for women, engagement may be more important. A discussion of the constructs of work engagement and developmental work personality is included.     

Expectancy and academic achievement

Two possible explanations of the relationship between expectancy and subsequent academic achievement were formulated and tested. The assumption that goal setting, by influencing actual and intended effort expenditure, might also determine both expectancy and subsequent performance, and thereby explain the relationship between the latter two variables, found little support. The hypothesis that expectancy determines how hard people work and thereby how well they perform found support only in a male group. Moreover, when previous academic achievement, goal setting, and effort expenditure were all controlled, expectancy was still found to relate to subsequent grades for both women and men. It was concluded that neither goal theory nor effort calculation theory could fully account for the relationship between expectancy and academic achievement.     

Do you get what you pay for? Sales incentives and implications for motivation and changes in turnover intention and work effort

This study investigated relations between pay-for-performance incentives designed to vary in instrumentality (annual pay-for-performance, quarterly pay-for-performance, and base pay level) and employee outcomes (self-reported work effort and turnover intention) in a longitudinal study spanning more than 2 years. After controlling for perceived instrumentality, merit pay increase, and the initial values of the dependent variables, the amount of base pay was positively related to work effort and negatively related to turnover intention, where both relationships were mediated by autonomous motivation. The amounts of quarterly and annual pay-for-performance were both positively related to controlled motivation, but were differently related to the dependent variables due to different relations with autonomous motivation.     

Risk Versus Effort in the Assessment of Motor Fatigue

The choice of probability leffort (COPE) devices require fatigued subjects to choose between risk and effort. In a first experiment, where fatigue was induced by an intense or by a prolonged motor task and where the required effort was perceptual, the fatigue did not generalize to the test mode. A second experiment used motor fatigue of the arm or leg, and tested with arm muscle effort, showing that subjects fatigued with either limb chose riskier alternatives in order to avoid the effort. The data correlated with self-rated fatigue, and closely paralleled earlier work using perceptual fatigue and perceptual effort.     

The Work Process as Spatial Situation: A Sketch

Interacting with the work of art entails a spatial situation, which is double. On a mental plane it is encapsulated reverie, on a physical plane it is production and consumption. These two are woven together as an orthogonal text or texture. The space of the work of art thus contains both the process of its making and its viewing. Seen as a dimensional space it is non linear. It is characterized by oscillations, discepancies, misalignements, multiplicity and recurrence. There is a correspondance between the studio and the exhibition area, as well as a dialogue between privileged and unprivileged spaces. The situation has something in common with oneiric space, where weightlessness and gravity oscillate.     

The role of self-concordance for self-reported strategic,tactical, and operational eco-driving

Although most people are aware of the harmful CO₂ emissions produced by the transport sector threatening life on earth now and in the future, they do not eco-drive. Eco-driving improves the vehicle’s fuel or energy economy and reduces greenhouse gas emissions. We investigated the motivational predictors of eco-driving based on the theory of self-concordance (i.e., the consistency between a behavior/goal with the person’s pre-existing values and interests). Data from a cross-sectional online survey with 536 German drivers revealed that self-reported eco-driving was significantly predicted by sustained effort towards eco-driving, which in turn was predicted by self-concordance variables. Therefore, individuals pursuing eco-driving out of strong interest or deep personal beliefs (i.e., autonomous motivation) as opposed to external forces or internal pressures (i.e., controlled motivation) reported greater effort towards this behavior. Furthermore, biospheric striving coherence, i.e., the coherence between personal valuable biopsheric values (i.e., values addressing the well-being of the environment/biosphere) and eco-driving, significantly predicted effort towards eco-driving. In sum, our results suggest that autonomous rather than controlled motives and coherence between behavior and intrinsic rather than extrinsic values are relevant predictors for eco-driving. We discuss implications for future strategies and interventions fostering eco-driving in the long term.     

Sensation of effort and duration of mentally executed actions

The aim of this study was to examine whether a sensation of effort would arise in subjects requested, by verbal instructions, to mentally perform motor tasks with an internal imagery strategy. Sixteen subjects had to imagine themselves, from a first person perspective, writing a sentence and drawing a Necker's cube either with their right dominant hand or with their left hand, as well as hopping around a square either on their right or left foot. The time needed to mentally execute these actions was measured. The sensation of effort following the mental performance and the difficulty of imaging the tasks were assessed by means of two analog rating scales. The results indicate that the sensation of effort increased across the trials. Furthermore, a negative correlation coefficient (mean r = -0.99) was found between the difficulty to imagining a given motor task and the subjective sensation of effort across the trials. Moreover, the sensation of effort was more pronounced when the tasks involved the non-dominant limb.     

Longitudinal tests on the influence of achievement goals on effort and intrinsic interest in the workplace

This study investigates whether four types of achievement goals—mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance—influence effort and intrinsic interest at work. Cross-lagged panel analyses were applied to data from a two-wave survey conducted on 57 newly hired Japanese police officers. The results showed that performance-approach goals had significant positive influences on effort and intrinsic interest. In contrast, performance-avoidance goals had significant negative impacts on the abovementioned two outcome variables. Longitudinal effects were observed when the influence of competence expectancy was controlled. These results highlight the benefits of performance-approach goals and the costs associated with performance-avoidance goals in the workplace.     

Effects of performance anxiety on effort and performance in rock climbing: A test of processing efficiency theory

Abstract

Three studies examined the effort and performance of rock climbers in the context of processing efficiency theory. Anxiety was manipulated by different means in the three studies. In each study, the effort due only to the physical exertion of climbing was controlled for. Anxiety, effort, and performance were measured via self-report, an integrated heart rate measure, and belayer observation. Consistent with processing efficiency theory, the results showed that higher levels of anxiety were usually associated with higher levels of effort and commensurately higher levels of performance. However, the results also suggested that cognitive anxiety may not be the prime determinant of the effort and performance changes observed. Finally, the results suggested that other individual difference variables may play an important part in determining the extent to which individuals may be able to make use of anxiety-induced effort.

Performance in a computerized self-control task by rhesus macaques (Macaca mulatta): The combined influence of effort and delay

The variables of delay and effort have been found to influence self-control predictably and in similar fashion when tested independently, but it is unclear how they influence self-control interactively. In the present study, I tested these two variables simultaneously to gain better understanding of their combined influence on self-control. A computerized task was employed in which monkey participants could sequence 1 or more digital images before “cashing-out,” after which they would receive their accumulated rewards. Delay was manipulated by adjusting the speed of the cursor used to select images. Cognitive effort was manipulated by presenting image sets that appeared in either a constant or a randomized configuration. For most monkeys, an interaction was found between the effects of delay and effort on the number of images selected before cashing-out. The results suggest that, when combined, these two variables have a complex influence on self-control.     

Conscious awareness of motor fluidity improves performance and decreases cognitive effort in sequence learning

Motor skill learning is improved when participants are instructed to judge after each trial whether their performed movements have reached maximal fluidity. Consequently, the conscious awareness of this maximal fluidity can be classified as a genuine learning factor for motor sequences. However, it is unknown whether this effect of conscious awareness on motor learning could be mediated by the increased cognitive effort that may accompany such judgment making. The main aim of this study was to test this hypothesis in comparing two groups with, and without, the conscious awareness of the maximal fluidity. To assess the possible involvement of cognitive effort, we have recorded the pupillary dilation to the task, which is well-known to increase in proportion to cognitive effort. Results confirmed that conscious awareness indeed improved motor sequence learning of the trained sequence specifically. Pupil dilation was smaller during trained than during novel sequence performance, indicating that sequence learning decreased the cognitive cost of sequence execution. However, we found that in the group that had to judge on their maximal fluidity, pupil dilation during sequence production was smaller than in the control group, indicating that the motor improvement induced by the fluidity judgment does not involve additional cognitive effort. We discuss these results in the context of motor learning and cognitive effort theories.     

The contribution of covariation to skill improvement is an ambiguous measure: comment on Müller and Sternad (2004)

It has been proposed that it is possible to decompose changes in variability of human motor behavior into 3 independent components: covariation, task tolerance, and stochastic noise (H. Müller & D. Sternad). The authors simulate learning to throw accurately and show that for this task the proposed analysis does not give an unambiguous answer to the question of what the 3 components contribute to the simulated skill improvement. It is argued that this is caused by the fact that the component covariation depends on the choice of control variables. The authors conclude that it is not possible to distinguish between the 3 components of noise reduction without knowing the controlled variables.     

Effects of imagery training on cognitive performance and use of physiological measures as an assessment tool of mental effort

The effectiveness of motor imagery training on cognitive performance was examined and the physiological mechanisms involved in the contribution of mental practice to motor learning were considered. The subject's mental effort during motor imagery was assessed by using psychophysiological measures and particularly eye blink activity as an 'indirect' measurement of subjects' attention. An electronic flight simulation program (Multiple Attribute Task Battery--MATB) was used to assess performance. Twenty healthy volunteers participated in the study divided in two groups: the control group and the imagery-training group. The subjects of the imagery group were asked for additional imagery training. The subjects of the actual performing group were asked additionally to passively observe the task in order to have equal time of exposure to the task. Performance scores and physiological parameters such as heart rate, respiratory rate, eye blinking activity and muscular activity were recorded during all sessions. The results revealed significantly higher performance level of the imagery-training group than the control group. Heart rate and respiratory rate significantly increased during imagery sessions compared to rest. A slight electromyographic activity was observed during the imagination of movement. Our findings support the notion that mental practice improves motor performance in a task where spatiotemporal or dynamic control of the action is highly required. The effects of mental practice on motor performance could be explained by the existence of a top-down mechanism based on the activation of a central representation of the movements, since the vegetative activation during motor imagery seems to be centrally controlled.     

Relations between the motor and cognitive dimensions of preschool girls and boys

The aim of this study was to compare relations between latent motor dimensions and cognitive abilities of preschool boys and girls (N=665, age: 5 to 6 years). The psychological part of the testing was implemented with the Test Razkol. For the assessment of motor abilities 28 tests were given. The associations of motor and cognitive variables were estimated by multiple regression analysis, which showed positive and significant associations between the latent motor variables and the cognitive variable for both boys and girls. On both sexes, the motor dimensions with the strongest associations with the cognitive abilities are those of coordination and the speed of movement. Despite some differences between boys and girls, they still have a lot in common since the most important latent motor dimensions prevailing in the connection between motor and cognitive dimensions are similar.     

An explanatory model of academic achievement based on aptitudes, goal orientations, self-concept and learning strategies

As a result of studies examining factors involved in the learning process, various structural models have been developed to explain the direct and indirect effects that occur between the variables in these models. The objective was to evaluate a structural model of cognitive and motivational variables predicting academic achievement, including general intelligence, academic self-concept, goal orientations, effort and learning strategies. The sample comprised of 341 Spanish students in the first year of compulsory secondary education. Different tests and questionnaires were used to evaluate each variable, and Structural Equation Modelling (SEM) was applied to contrast the relationships of the initial model. The model proposed had a satisfactory fit, and all the hypothesised relationships were significant. General intelligence was the variable most able to explain academic achievement. Also important was the direct influence of academic self-concept on achievement, goal orientations and effort, as well as the mediating ability of effort and learning strategies between academic goals and final achievement.     

A test of optimal theory on young adolescents' standing long jump performance and motivation

The OPTIMAL theory of motor learning contends that an external focus of attention (EF), enhanced expectancies (EE), and autonomy support (AS) are key attentional and motivational variables that optimise motor performance. We examined how integrating an EF into EE and AS interventions would impact young adolescents' standing long jump performance and self-efficacy, perceived competence, task effort, task importance and positive affect. Forty-eight participants completed 3 jumps in a baseline, EF (focus on jumping towards the cone), EE-EF (positive social-comparative feedback/high success probability) and AS-EF (self-definition of success) conditions. Both the EF and AS-EF conditions (but not the EE-EF condition) improved jump performance from baseline. The EF, EE-EF and AS-EF conditions improved young adolescents' self-efficacy, perceived competence, task effort and positive affect in comparison to baseline and were predictors of jump performance (as was task importance). However, in the EE-EF condition motivational states improved (from baseline) but this did not translate into performance improvements. The findings show that directing attention to visual external cues both independently and when framed within AS conditions enhanced young adolescents' jump performance and motivation through efficient goal-action coupling. In practice, PE teachers and sports coaches working with young adolescents can support autonomy by allowing self-definition of success using an external cue to enhance effective goal-action coupling, motor performance and motivation.     

Yes,they can! Efficient physical effort mobilization according to task difficulty in schizophrenia

The current literature has largely highlighted a deficit of effort-based decision-making for reward in schizophrenia. However, not all studies have dissociated effort from reward, while other studies emphasize that difficulty is the main determinant of effort rather than reward. In this study, 33 individuals with schizophrenia and 32 healthy controls were recruited to perform a decision-making isometric force task. According to motivational intensity theory, task difficulty (i.e., required force) but not reward was manipulated from easy to impossible. Accuracy between force exerted and force required, and choice to perform a task or not were our effort measures. Clinical variables including depression, defeatist beliefs, and apathy were assessed. Our results demonstrated that the schizophrenia group chose to perform easy, moderate, and difficult tasks and exerted the necessary effort to succeed similarly to the non-clinical group. No association between effort and clinical variables was found. Our findings provide new understandings related to effort mechanisms in schizophrenia.
