Functional relations and cognitive psychology: Lessons from human performance and animal research

We consider requirements for effective interdisciplinary communication and explore alternative interpretations of “building bridges between functional and cognitive psychology.” If the bridges are intended to connect radical behaviourism and cognitive psychology, or functional contextualism and cognitive psychology, the efforts are unlikely to be successful. But if the bridges are intended to connect functional relationships and cognitive theory, no construction is needed because the bridges already exist within cognitive psychology. We use human performance and animal research to illustrate the latter point and to counter the claim that the functional approach is unique in offering a close relationship between science and practice. Effective communication will be enhanced and, indeed, may only occur if the goal of functional contextualism extends beyond just “the advancement of functional contextual cognitive and behavioral science and practice” to “the advancement of cognitive and behavioral science and practice” without restriction.     

Resilience and Subjective Wellbeing: A Psychometric Evaluation in Young Australian Adults

Objective

Resilience is an important and underdeveloped area of research, and there are few studies that describe levels of resilience among youth samples. A major aim of this research is to explore the utility of an adapted form of the 10‐item Connor Davidson Resilience Scale and to clarify the association between this construct and a robust measure of subjective wellbeing.

Method

A representative sample of 1000 Victorians aged 16–25 years participated in a telephone interview comprising the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index.

Results

The modified 10‐item Connor Davidson Resilience Scale demonstrated adequate inter‐item reliability and factored as intended. A moderate, positive correlation was found between the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index. Significance testing revealed group differences for gender, age, and annual household income. The results are also used to establish theoretical “normal” ranges for resilience in Victoria's youth population.

Conclusion

The results from this study support the modified 10‐item Connor Davidson Resilience Scale as a valid and reliable measure of young people's resilience using traditional psychometric tests. Moreover, this is the first study to describe the levels of resilience among Victorian youths and to evaluate these data alongside a robust measure of subjective wellbeing. The implications of the findings for government policy and service delivery are discussed.     

Do Perceptual Instructions Lead to Enhanced Performance Relative to Behavioral Instructions?

As people we commonly instruct people in terms of physical actions to carry out to perform any task. However, according to perceptual control theory (Powers, 1973 Powers, W. T. (1973). Behavior: The control of perception. Chicago, IL: Aldine. [Google Scholar]), human action serves to control perception. Using a drawing task, it was hypothesized that instructions describing the perceivable effects of the movement would result in greater accuracy of image drawing than those describing the movement. Participants were asked to draw images using different instructions; describing the expected perceptions and describing the movements. As predicted, it was found that describing the perceptual outcome of the task led to significantly more accurate drawings than describing the movements did. This highlights the importance of instructions based on desired perceptions when precise execution of a skill is necessary.

身体活动与学业成绩:来自具身认知的启示

具身认知理论认为身体、认知和环境是和谐的统一体。以该理论为基础的具身学习认为,身体不是学习过程的无关因素或障碍因素,身体是学习的主体,身体活动的参与在塑造学习者的思维、判断及记忆等心智活动中具有重要作用。当前已有一定数量的实证研究发现,身体活动能够显著提供语言习得、数学学习等学业成绩,提供学生在同伴中的社会地位。将来,可基于具身认知的角度,采用认知神经科学、心理学和教育学等跨学科合作的方式,进一步探讨具身学习影响学业成绩的因素及其机制。     

Heuristics and biases in mental arithmetic: revisiting and reversing operational momentum

ABSTRACT

Mental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum (OM) effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems (e.g., 3+0, 3?0) but reverse OM with non-zero problems (e.g., 2+1, 4?1). In a third experiment, we tested the prediction of our model. Our results suggest the presence of at least three competing biases in mental arithmetic: a more-or-less heuristic, a sign-space association and an anchoring bias. We conclude that mental arithmetic exhibits shortcuts for decision-making similar to traditional domains of reasoning and problem-solving.     

Proactive vitality management in the work context: development and validation of a new instrument

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM.     

Procrastination and predictor variables among a group of dental students in Turkey

The aim of this study was to assess the prevalence of procrastination among a group of Turkish dental students and to determine the predictors and consequences of procrastination. A total number of 273 females and 179 males (aged between 18 and 28) were included in the study. Tuckman procrastination scale, Academic Life Satisfaction Scale, Concern over Mistake Scale, Poor Time Management Scale, Self-Doubt Scale, Irrational Beliefs about Studying Scale, Positive and Negative Affect Schedule and Life Satisfaction Scale were used to gather data. Results indicated that 50% of participants were more likely to procrastinate their academic assignments or tasks. Procrastination score did not differ according to gender. The findings suggested that procrastinating students had a higher level of poor time management, self-doubt and irrational beliefs about studying, and poor academic performance and well-being than their non-procrastinating counterparts. Preventive strategies are necessary to overcome procrastination which affects the academic achievement, satisfaction, and well-being of dental students.     

“Please watch right” – Evaluation of a speech-based on-demand assistance system for urban intersections

In a driving simulator study we evaluated a speech-based driver assistance system for urban intersections (called Assistance on Demand AoD system) which supports the driver in monitoring and decision making. The system provides recommendations for suitable time gaps to enter the intersection based on the observation of crossing traffic. Following an “on-demand”-concept, the driver activates the assistance only if support is desired.In one drive, drivers used the AoD system in every situation they experienced to guarantee that every driver had the same exposure to the system when evaluating it. During another drive, drivers were free to decide if they want to use the system or not. The experimental study compared the AoD system with driving manually and with driving supported by a more conventional visual-based system which was always active at intersections (system showing colored arrows in a simulated head-up display (HUD) to visualize the crossing traffic). This resulted in four drives the drivers had to perform. Every drive consisted of several intersections with varying traffic conditions. The drivers had to turn left at every intersection.A total of 24 drivers took part in the study; one group with 14 middle-aged drivers and another group with ten high-aged drivers. Several questionnaires and online ratings were used to assess drivers’ acceptance, perceived usefulness, benefits and specific characteristics of both system variants. In addition, driving behaviour with regard to gap choice and drivers’ monitoring behaviour (using head tracking data) were analyzed.The results show that the AoD system reaches high acceptance ratings and is preferred compared to the visual, always active system. Using the speech modality for communication and the on-demand concept were both highly appreciated by the drivers. With regard to driving behaviour, the AoD system is comparably safe as manual driving while at the same time making driving easier by facilitating the monitoring of vehicles while waiting at an intersection.
