Understanding “His and Her” Work-Family Conflict and Facilitation

Work-family conflict (negative spillover between work and family) and work-family facilitation (positive spillover between work and family) are two aspects of the work-family interface. Prior work has established that these constructs are statistically and conceptually distinct, but less is known about what work and family characteristics are associated with conflict versus facilitation. Understanding who is most at risk for conflict and most benefiting from facilitation is necessary for establishing effective workplace policies. We used structural equation modeling to determine whether (1) work-family conflict and facilitation have different (statistical) predictors, and (2) whether these predictive relations are moderated by gender. Perceiving more work demands predicted greater work-family conflict, but was unrelated to facilitation. Perceiving more skill discretion at work and being married predicted greater work-family facilitation, but was unrelated to work-family conflict. Perceiving more decision authority and social support at work, and having more children, predicted less conflict and more facilitation. Most predictors were stronger for men than for women. We discuss implications of these results for designing effective policies to increase work-family facilitation and decrease work-family conflict for men and women.     

How attentional focus on body sway affects postural control during quiet standing

The purpose of this study was to investigate how attentional focus on body sway affects postural control during quiet standing. To address this issue, sixteen young healthy adults were asked to stand upright as immobile as possible on a force platform in both Control and Attention conditions. In the latter condition, participants were instructed to deliberately focus their attention on their body sways and to increase their active intervention into postural control. The critical analysis was focused on elementary motions computed from the centre of pressure (CoP) trajectories: (1) the vertical projection of the centre of gravity (CoG_v) and (2) the difference between CoP and CoG_v (CoP–CoG_v). The former is recognised as an index of performance in this postural task, whilst the latter constitutes a fair expression of the ankle joint stiffness and is linked to the level of neuromuscular activity of the lower limb muscles required for controlling posture. A frequency-domain analysis showed increased amplitudes and frequencies of CoP–CoG_v motions in the Attention relative to the Control condition, whereas non-significant changes were observed for the CoG_v motions. Altogether, the present findings suggest that attentional focus on body sway, induced by the instructions, promoted the use of less automatic control process and hampered the efficiency for controlling posture during quiet standing.     

Low-ball and compliance to a request: an application in a field setting

The low-ball refers to a compliance technique in which a demand of someone to agree to a request is followed by telling the person the real cost of the request. The number of people who maintain their first decision is larger than the number in the condition in which the real cost of the request is stated prior to the initial compliance. Researches in this paradigm traditionally included a request addressed by a professor to students but was never tested between strangers. So, an experiment was carried out in which people were solicited to keep a dog (8 kg) on a lead until a male confederate returned from a visit to someone in a hospital. In low-ball condition, the confederate told the subject who agreed to the request that it would take 30 min., whereas in the control condition the confederate gave this information when stating his request. Analysis showed that low-ball technique leads people to maintain their first decision.     

Touch,awareness of touch,and compliance with a request

In certain situations it has been shown that touch has a positive effect on the compliance with a request expressed by a stranger. However, the difference between the effect of touch on request compliance between people who had noticed and those who had not noticed this contact has never been taken into account. In this experiment a female confederate asked 227 women to answer a questionnaire. When asking for their collaboration the forearm was or was not touched for a brief period of 1 to 2 seconds. Analysis showed that touch was associated with significantly higher compliance to the request but no difference was found between subjects who had noticed the tactual contact and subjects who had not noticed.     

Alfred Binet and higher education

At the beginning of the 20th century, Alfred Binet sought teaching positions at the Collége de France and the Sorbonne. Binet wanted to develop experimental psychology in France, but the strong psychopathological orientation of French psychology blocked his ambition. The 1st part of this article relates the history of the introduction of psychology, via Théodule Ribot, to the Sorbonne and the Collège de France. Ribot's premature retirement from the Collège de France in 1901 triggered a battle that led to Binet's repeated failure to gain access to these institutions of highter education and the success in 1902 of Ribot's students: Pierre Janet at the Collège de France and George Dumas at the Sorbonne.     

Functional balance and dual-task reaction times in older adults are improved by virtual reality and biofeedback training.

Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in both traumatic brain injury (TBI) survivors and elderly subjects. Similarly, computer-based biofeedback (BF) training has resulted in decreased sway during quiet stance and decreased reaction times during a dual-task reaction time paradigm in elderly subjects. The objective of this study was to determine the effect of VR and BF training on balance and reaction time in older adults. Two groups of twelve healthy older adults completed 10-week training programs consisting of two 30-min sessions per week. VR training required that participants lean sideways to juggle a virtual ball. Participants in the BF group viewed a red dot representing their center of gravity on a screen and were required to move the dot to the four corners of the monitor. Measures of functional balance and mobility (Community Balance and Mobility Scale [CB&M]), sway during quiet stance, and reaction time during a dual task paradigm were recorded before training, as well as 1 week and 1 month after the end of the program. Both groups showed significant improvements on the CB&M, as well as decreased reaction times with training. Postural sway during quiet stance did not change significantly.     

Tactile contact and evaluation of the toucher

The authors investigated the effect of touch on a person's evaluation of the toucher in a field setting. In the context of selling a 2nd-hand car, the authors instructed a male seller to slightly touch (or not touch) a man who was interested in the car. After the participant left the seller, a female confederate solicited him, asking him to evaluate the car seller on various dimensions. The results showed that for each dimension that the participants evaluated, the touch condition was associated with statistically higher positive evaluations of the toucher than the no-touch control condition.     

The Equiprobability Bias from a Mathematical and Psychological Perspective

The equiprobability bias (EB) is a tendency to believe that every process in which randomness is involved corresponds to a fair distribution, with equal probabilities for any possible outcome. The EB is known to affect both children and adults, and to increase with probability education. Because it results in probability errors resistant to pedagogical interventions, it has been described as a deep misconception about randomness: the erroneous belief that randomness implies uniformity. In the present paper, we show that the EB is actually not the result of a conceptual error about the definition of randomness. On the contrary, the mathematical theory of randomness does imply uniformity. However, the EB is still a bias, because people tend to assume uniformity even in the case of events that are not random. The pervasiveness of the EB reveals a paradox: The combination of random processes is not necessarily random. The link between the EB and this paradox is discussed, and suggestions are made regarding educational design to overcome difficulties encountered by students as a consequence of the EB.
