Scale of expectations of control and responsibility: adaptation to the Spanish language and its relation to personal initiative

Personal initiative, understood as a proactive behaviour, self-initiated, persistent and pro-organization, is indispensable in contemporary organizations immersed in an environment of rapid and complex changes and innovations. In this work, one of the antecedents of personal initiative in the work setting is analyzed: the expectations or hopes of control and responsibility. We studied the adaptation to Spanish of the Scale of Expectations of Control and Responsibility of Frese and colleagues, using two cross-sectional samples (n=414 and 396, respectively). We performed exploratory and confirmatory factorial analyses that positively replicate the factor structure of the original scale. The relation of the expectations of control with personal initiative is confirmed, as suggested in the general model of antecedents and consequences of personal initiative. Likewise, the study confirms that control can be considered an antecedent of expectations of control and responsibility.     

Motivational climate and coaches' communication style predict young soccer players' commitment

The purpose of this research was to study the role of coaches' communication style and coach-created motivational climate in young soccer players' enjoyment and commitment. Four hundred and fifteen young soccer players of high competitive level in the age range from 14 to 16 completed the following questionnaires: a) coach-induced perceived motivational climate (PMCSQ-2), b) coaches' behaviour perception (CBAS-PBS), and c) sport commitment (SCQ). Results showed that coach-created motivational climate correlated highly with the perception of coaches' communication style. Moreover, coach-created motivational climate and communication style significantly determines players' sport commitment and enjoyment. Discussion focuses on the importance of seeking and training credible coaches that favours athletes' commitment.     

Anxiogenic-like effects of gamma-hydroxybutyric acid (GHB) in mice tested in the light-dark box

Gamma-hydroxybutyric acid (GHB) is a drug with abuse potential, popularly known as "liquid ecstasy". It is an endogenous compound of the mammalian brain which satisfies many of the criteria for consideration as a neurotransmitter or neuromodulator. In this study, the effects of acute administration of GHB (40, 80 and 120 mg/kg, ip) on anxiety, tested in the light/dark box, were examined in male mice of the OF.1 strain. Likewise, we compared the behavioural profile of GHB with that induced by mCPP (1 mg/kg, ip), a compound with known anxiogenic actions. GHB-treated mice spent notably less time in the lit area (40 and 80 mg/kg) and more time in the dark area (all doses), whereas the total number of 'rearings', transitions and latency were significantly reduced. A very similar behavioural profile was observed in mCPP-treated animals. Overall, these findings indicate that GHB exhibits anxiogenic-like properties in male mice. It is suggested that the anxiogenic effects of GHB could be related to its ability to modulate GABA and/or dopaminergic receptors.     

Influence pattern effectiveness

Managers apply different influence tactics to get subordinates to perform their tasks. For a better understanding of the influence process dynamics, it has been recommended to consider the combination of different tactics instead of analyzing them separately. (Cialdini & Goldstein, 2004). The present study has analyzed the effectiveness of various influence tactics combinations used by superiors with their subordinates. We identified four influence patterns: hard pattern, rational pattern, active pattern and passive pattern. Pattern effectiveness was analyzed in terms of subordinates' satisfaction, commitment and well-being. We found that superiors who used a broader range of tactics were more effective than those using a single range of tactics. Practical implications are discussed.     

Say-do correspondence to improve disruptive behaviors in adults with Down's syndrome

The most acknowledged strategies for the treatment of disruptive behaviours are those that are based on direct contingency management. Other procedures allow the therapist, or educational agent, not to be present in the context in which the behavioural change has to take place: the say-do correspondence training procedures, which have proven effective across behaviours and populations. Nevertheless, there is surprisingly little evidence of the effectiveness of such procedures with populations presenting developmental disabilities. This study describes the implementation of say-do correspondence training to modify 5 disruptive behaviours present in 5 adult subjects diagnosed with Down's syndrome, showing very positive results. The advantages of using say-do correspondence training procedures in developmental disabilities are discussed.     

Are the effects of Unreal violent video games pronounced when playing with a virtual reality system?

This study was conducted to analyze the short-term effects of violent electronic games, played with or without a virtual reality (VR) device, on the instigation of aggressive behavior. Physiological arousal (heart rate (HR)), priming of aggressive thoughts, and state hostility were also measured to test their possible mediation on the relationship between playing the violent game (VG) and aggression. The participants--148 undergraduate students--were randomly assigned to four treatment conditions: two groups played a violent computer game (Unreal Tournament), and the other two a non-violent game (Motocross Madness), half with a VR device and the remaining participants on the computer screen. In order to assess the game effects the following instruments were used: a BIOPAC System MP100 to measure HR, an Emotional Stroop task to analyze the priming of aggressive and fear thoughts, a self-report State Hostility Scale to measure hostility, and a competitive reaction-time task to assess aggressive behavior. The main results indicated that the violent computer game had effects on state hostility and aggression. Although no significant mediation effect could be detected, regression analyses showed an indirect effect of state hostility between playing a VG and aggression.     

Modulating effects in learned helplessness of dyadic dominance-submission relations

In this experiment, learned helplessness was studied from an ethological perspective by examining individual differences in social dominance and its influence on the effects of helplessness. Ninety animals were used, 30 randomly selected and 60 selected because of their clear dominance or submission. Each condition (dominant, submissive, and random) was distributed in three subgroups corresponding to the triadic design. The test consisted of an escape/avoidance task. The results showed that the animals in the uncontrollable condition performed worse than those in the controllable and no treatment conditions. Social submission and dominance reduced vulnerability of the subjects against learned helplessness. Submission had a facilitating effect on subsequent learning, independently of whether pretreatment was controllability or uncontrollability. Learned mastery was observed in the submissive condition, because submission benefited the subjects in the controllable condition in comparison with the untreated subjects, and dominance impaired the subjects in the controllable condition.     

Incorporating randomness in the Fisher information for improving item‐exposure control in CATs

The most commonly employed item selection rule in a computerized adaptive test (CAT) is that of selecting the item with the maximum Fisher information for the estimated trait level. This means a highly unbalanced distribution of item‐exposure rates, a high overlap rate among examinees and, for item bank management, strong pressure to replace items with a high discrimination parameter in the bank. An alternative for mitigating these problems involves, at the beginning of the test, basing item selection mainly on randomness. As the test progresses, the weight of information in the selection increases. In the present work we study, for two selection rules, the progressive methods ( Revuelta & Ponsoda, 1998 ) and the proportional method ( Segall, 2004a ), different functions that define the weight of the random component according to the position in the test of the item to be administered. The functions were tested in simulated item banks and in an operative bank. We found that both the progressive and the proportional methods tolerate a high weight of the random component with minimal or zero loss of accuracy, while bank security and maintenance are improved.     

Unless reasoning

We report the results of two experiments investigating conditional inferences from conditional unless assertions, such as Juan is not in León unless Nuria is in Madrid. Experiments 1 and 2 check Fillenbaum's hypothesis about the semantic similarity of unless with if not and only if assertions; both also examine inferential endorsements (Experiment 1) and endorsements and latencies (Experiment 2) of the four logically equivalent conditional formulations: if A then B, if not-B then not-A, A only if B and notA unless B. The results of these experiments show the similarity of unless and only if confirming that the representation of both conditionals from the outset probably include two possibilities directionally oriented from B to A; results also confirm the especial difficulty of unless assertions. The implications of the results are discussed in the context of recent psychological and linguistic theories of the meaning of unless.     

Materialism as a predictor variable of low income consumer behavior when entering into installment plan agreements

• This paper explores the influence of materialism on consumer indebtedness among low income individuals who live in poor regions of Sao Paulo. A materialism scale was adapted to this context and used to describe the level of materialism among the population surveyed. Results obtained relative to the relationship between materialism and socio‐demographic variables are compared to those of previous studies. A logistic regression model was developed in order to characterize individuals who have an installment plan payment booklet—the main source of consumer credit for the population studied—and to differentiate them from those who do not, based on the materialism level, socio‐demographic variables and purchasing and consumer habits. The proposed model confirms materialism as a behavioral variable that is useful for forecasting the probability of an individual getting into debt in order to consume. Income had the biggest relative influence on the regression model, followed by materialism and age, controlled by gender.
