The differential effect of background music on memory for verbal and visuospatial information

Background music is a part of our everyday activities. Considerable evidence suggests that listening to music while performing cognitive tasks may negatively influence performance. However, other studies have shown that it can benefit memory when the music played during the encoding of information is also provided during the retrieval of that information, in the so-called context dependent memory effect. Since controversial results may be attributed to the nature of the material to be memorized, the aim of the present study is to compare the potential effect of consistent background music on the immediate and long-term recall of verbal and visuospatial information. Experiment 1 showed that instrumental background music does not benefit nor decrease recall of a list of unrelated words, both at the immediate and the 48-hours-delayed tests. By contrast, Experiment 2 revealed that the same background music can impair immediate and therefore long-term memory for visuospatial information. Results are interpreted in terms of competition for neurocognitive resources, with tasks mostly relying on the same brain hemisphere competing for a limited set of resources. Hence, background music might impair visuospatial memory to a greater extent than verbal memory, in the context of limited capacity cognitive system. In conclusion, the nature of the material to be learnt must be considered to fully understand the effect of background music on memory.     

The Factor Structure of the State-Trait Anxiety Inventory: An Alternative View

Wagner and Copper (1963) reported high discriminative power for one score (the ACTivity score) of the Wagner Hand Test between (unskilled and semi-skilled) workers at Goodwill Industries, Akron, Ohio who had been rated “Satisfactory” or “Unsatisfactory” by their superiors.

An attempt to crossvalidate this finding, in a three-group design, in a large Western Canadian Plywood mill failed to produce the expected relationship; neither the ACT score, nor any of the other scores derived from this test showed any consistent trend in terms of postdicting activity level, or general acceptability of the 18 Ss involved in this study.     

Effect of Depressive Symptoms and Sex on the Relationship Between Loneliness and Cigarette Dependence: A Moderated Mediation

Loneliness is a subjective and emotionally unpleasant experience of perceiving insufficient social relationships. Previous research has revealed that loneliness constitutes a psychosocial risk factor for depression, and is also related to unhealthy behaviors such as smoking. This study aims to examine the relation between loneliness, depression, and cigarette dependence, and to explore the role of sex in this relationship. A total sample of 275 adult treatment-seeking daily smokers (Mage = 45.3; 61.5% females) was used. Our results showed a significant correlation between higher scores of loneliness, depressive symptoms, and cigarette dependence. In addition, mediation analysis showed a significant indirect effect of loneliness on cigarette dependence, via depressive symptoms. Regarding the effect of sex, we found that this variable significantly moderated the relationship between depressive symptoms and cigarette dependence. Results of this study extend previous literature by showing that, in treatment seeking smokers, loneliness is a significant predictor of depressive symptoms, and through this relation, it predicts cigarette dependence. Additionally, sex was a significant moderator of this relation. These findings have several clinical implications, and also contribute to the understanding of cigarette dependence, which is a well-known barrier for smoking cessation.     

Validity and Reliability of Three Rating Scales to Assess Practitioners’ Skills to Conduct Collaborative,Strength-Based,Systemic Work in Family-Based Services

This study analyzed the reliability and validity of three rating scales designed to assess practitioners’ skills in conducting systemic, collaborative, and strength-based assessments and interventions with multi-challenged families in family-based community services. The three scales, which assess reception and assessment skills, basic skills, and skills to support change, revealed good psychometric properties considering their construct validity, internal consistency, and inter-rater agreement. The results are discussed considering future research and possible applications of the scales in research and practice.     

The role of emotions arising from instability in investment behaviour / El papel de la carga emocional de la inestabilidad en el comportamiento de inversión

Abstract

Clear empirical evidence has been found on how significant changes to a person’s environment can alter their behaviour. This is important when considering investments made on the stock exchange as the variations that occur in stock market prices are frequent and continuous. This study analyses the role instability has on individual investors’ behaviour when investing in the stock market. The results suggest that instability in investment situations plays a significant role in individual investors’ behaviour, probably due to the emotional effect provoked by the possibility of suddenly losing savings. This would modify the perception investors have about investing as well as their intentions, attitudes and feelings of control in regards to investment in financial markets, thus hindering the capacity to predict their behaviour.     

Response to Comment: Starting to Solve the Method Puzzle in Salesperson Self-Report Evaluations

This response addresses the comments of Sharma, Rich, and Levy (2004) about the generalizability of the performance effect. The comments are addressed by bringing additional theoretical and empirical support with a new study that replicates and extends the results of our 2003 paper. Results confirm our 2003 findings that bottom performers overestimate and that top performers underestimate their job performance. Further, results confirm our 2003 findings that bottom performers are significantly more inaccurate than top salespeople in their performance estimation. Finally, this study extends previous research by providing evidence that the inaccuracy in self-evaluations is reduced when factualbased questions are used.     

A Meta-Analytic Comparison of Managerial Ratings and Self-Evaluations

The purpose of this study was to examine the equivalence of self-reports and managerial ratings of salesperson job performance. A meta-analysis showed that the two measures exhibited low convergent validity (mean corrected correlation = 0.19), which indicated that they are not interchangeable. The predictive validity of self-reports and managerial ratings was compared. Managerial ratings had a corrected mean correlation of 0.44 with objective performance, whereas the corrected mean correlation between self-reports and objective measures was 0.34. Further meta-analytic investigations showed that the divergence between self-reports and managerial ratings was attributable to the performance effect. A discussion of the findings and avenues for further research are also provided.     

Psychological Contracts and Their Implications for Job Outcomes: A Social Exchange View

This article explores the relationship between on the 1 hand psychological contract fulfilment and affective commitment and on the other hand, normative commitment and job satisfaction. We hypothesized that the perceived supervisor support (PSS) and the perceived organizational support (POS) mediate the relationship between the fulfilment of the psychological contract, commitment and job satisfaction. The sample consists in 337 soldiers in training. In order to test our model, we used 3 measures of psychological contract fulfilment (economic, socioemotional and developmental), PSS and POS measures as well as attitudes. Results show that the developmental psychological contract is related to affective and normative organizational commitment and job satisfaction whereas socioemotional fulfilment is unrelated to affective commitment. Psychological contract fulfilment has a greater impact on normative commitment than affective commitment. Results show also that only PSS plays a mediating role in psychological contract processes. Several implications emerge from this study. First, in a military context, it is important to strengthen the developmental psychological contract. Second, it is essential for organizations to place greater emphasis on encouraging supervisors to establish healthy working relationships with newcomers.     

Józef Bocheński and static religion

One of the most interesting aspects of Józef Bocheński’s philosophy was its relation to Henri Bergson’s thought, particularly to his philosophy of religion. Unlike the majority of the Catholic philosophers at that time, Bocheński did not stress the significance of dynamic religion, but rather focused on the role of static religion in human life. In his view, what was of particular interest within this religion was its fabulation function. This direction of the philosopher’s research stemmed from the realism and empiricism proper to the analytic philosophy developed by Bocheński and became increasingly visible as the years passed. In this text the author shows how Bocheński’s analyses of religion, referring to both daily human experiences and logic, moved towards Bergsonian static religion, while diverging from dynamic religion and its key notion of mysticism.
