Getting a tool gives wings: overestimation of tool-related benefits in a motor imagery task and a decision task

Two experiments examine whether people overestimate the benefits provided by tool use in motor tasks. Participants had to move different quantities of objects by hand (two at a time) or with a tool (four at a time). The tool was not within reach so participants had to get it before moving the objects. In Experiment 1, the task was performed in a real and an imagined situation. In Experiment 2, participants had to decide for each quantity, whether they preferred moving the objects by hand or with the tool. Our findings indicated that people perceive tool actions as less costly in terms of movement time than they actually are (Experiment 1) and decide to use a tool even when it objectively provides less time-based benefits than using the hands (Experiment 2). Taken together, the data suggest that people overestimate the benefits provided by tool use.     

Why does lag affect the durability of memory-based automaticity: Loss of memory strength or interference?

In Rickard, Lau, and Pashler's (2008) investigation of the lag effect on memory-based automaticity, response times were faster and proportion of trials retrieved was higher at the end of practice for short lag items than for long lag items. However, during testing after a delay, response times were slower and proportion of trials retrieved was lower for short lag items than for long lag items. The current study investigated the extent to which the lag effect on the durability of memory-based automaticity is due to interference or to the loss of memory strength with time. Participants repeatedly practiced alphabet subtraction items in short lag and long lag conditions. After practice, half of the participants were immediately tested and the other half were tested after a 7-day delay. Results indicate that the lag effect on the durability of memory-based automaticity is primarily due to interference. We discuss potential modification of current memory-based processing theories to account for these effects.     

Effects of working memory training in young and old adults

Many cognitive abilities, including working memory and reasoning ability, decline with progressing age. In this study, we investigated whether four weeks of intensive working memory training would enhance working memory and reasoning performance in an age-comparative setting. Groups of 34 young (19–36 years) and 27 older (62–77 years) adults practiced tasks representing the three functional categories in the facet model of working memory capacity: storage and processing, relational integration, and supervision. The data were compared to those of a young and an old active control group who practiced tasks with low working memory demands. A cognitive test battery measuring near and far transfer was administered before and after training. Both age groups showed increased working memory performance in the trained tasks and in one structurally similar, but nontrained, task. Young adults also improved in a task measuring word-position binding in working memory. However, we found no far transfer to reasoning in either age group. The results provide evidence that working memory performance can be improved throughout the life span. However, in contrast to a previous study in which each facet of working memory capacity was trained separately, the present study showed that training multiple functional categories simultaneously induces less transfer.     

The mediating role of positive and negative affect in the situational motivation-performance relationship

Based on self-determination theory (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum Publishing Co., New York, 1985) and the broaden-and-build theory (Fredrickson in Am Psychol 56:218–226, 2001), the purpose of the present research was to propose and test an integrative model on the role of positive and negative affect as mediators of the situational motivation-performance relationship. Specifically, the hypothesized model posits that autonomous motivation predicts positive affect, while controlled motivation and amotivation both lead to negative affect. In addition, amotivation negatively predicts positive affect. In turn, positive and negative affect positively and negatively predict performance, respectively. The model was confirmed in three studies using correlational (Studies 1 and 2) and experimental designs (Study 3) with a cognitive task (anagrams). In addition, the role of individual differences (Study 2) and situational factors (Study 3) as triggers of the “Motivation-Affect-Performance” sequence was confirmed. Theoretical implications and directions for future research are discussed.     

On the (In)Compatibility of Attitudes Toward Peace and War

Although attitudes toward peace and war are usually treated as two opposite poles of one dimension, in this article we argue that they may represent two distinct dimensions. To investigate this idea, we developed and tested a new balanced measure, the Attitudes Toward Peace and War (APW) Scale, in three studies (N = 4,742) in the United States and Denmark. Exploratory and confirmatory factor analyses showed that attitudes toward peace and war formed two distinct, though negatively related, factors. Structural equation modeling showed that antecedents of attitudes toward peace included egalitarian ideological beliefs, the values of international harmony and equality, and empathic concern for others, and consequences included intentions to engage in peace‐related activities. On the other hand, antecedents of attitudes toward war included authoritarian ideological beliefs, the values of national strength and order, and less personal distress, and consequences included intentions to engage in warlike activities. Results also showed that political affiliation had an impact on the relationship between peace and war attitudes, with conservatives less likely to find the attitudes incompatible. The findings support the view that attitudes toward peace and war represent two distinct dimensions.     

Zuckerman's Revised Alternative Five-Factor Model: Validation of the Zuckerman-Kuhlman-Aluja Personality Questionnaire in Four French-Speaking Countries

The aim of this study was to analyze the replicability of Zuckerman's revised Alternative Five-factor model in a French-speaking context by validating the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA–PQ) simultaneously in 4 French-speaking countries. The total sample was made up of 1,497 subjects from Belgium, Canada, France, and Switzerland. The internal consistencies for all countries were generally similar to those found for the normative U.S. and Spanish samples. A factor analysis confirmed that the normative structure replicated well and was stable within this French-speaking context. Moreover, multigroup confirmatory factor analyses have shown that the ZKA–PQ reaches scalar invariance across these 4 countries. Mean scores were slightly different for women and men, with women scoring higher on Neuroticism but lower on Sensation Seeking. Globally, mean score differences across countries were small. Overall, the ZKA–PQ seems an interesting alternative to assess both lower and higher order personality traits for applied or research purposes.     

The importance of feature distribution and correlation for simulating 3 to 4-month-old infants' visual categorization processes

Mareschal, French, and Quinn (2000) and Mareschal, Quinn, and French (2002) have proposed a connectionist model of visual categorization in 3- to 4-month-old infants that simulates and predicts previously unexplained behavioural effects such as the asymmetric categorization effect (French, Mareschal, Mermillod, & Quinn, 2004). In the current paper, we show that the model's ability to simulate the asymmetry depends on the correlational structure of the stimuli. These results are important given that adults (Anderson & Fincham, 1996) as well as infants (Younger & Cohen, 1986) are able to rely on correlation information to perform visual categorization. At a behavioural level, the current paper suggests that pure bottom-up processes, based on the correlational structure of the categories, could explain the disappearance of the asymmetry in older 10-month-old infants (Furrer & Younger, 2005). Moreover, our results also raise new challenges for visual categorization models that attempt to simulate the shift from asymmetric categorization in 3- to 4-month-old to symmetric categorization in 10-month-old infants (Shultz & Cohen, 2004; Westermann & Mareschal, 2004, 2012).     

‘Faking brands’: Consumer responses to counterfeiting

Whilst counterfeiting is regarded as one of the ‘oldest crimes in history’, contextualised treatments of Middle East and North Africa (MENA region) are rare despite growing interconnections with the global economy. Accordingly, this paper explores consumer motivations to purchase counterfeit products and identifies possible counter‐influences. Data from a survey of 400 respondents drawn from Morocco was tested with logistic regression models to determine the significant factors that trigger responsiveness and deterrence to counterfeit products. The tests were based on three product categories: clothing, cosmetics and mobile phones. Additionally, consumer demographics and selected social triggers were evaluated to build a profile of consumers typically likely to consider buying (or avoiding) counterfeit goods. Results show that concerns related to health, disappointment risk and integrity are the most significant countervailing factors on behavioural intentions towards purchasing counterfeits. On a socio‐demographic level, it was found that low‐income consumers are more positively disposed to buying counterfeits. Gender also seems to have an explanatory force. Women with higher educational backgrounds are less likely than men to consider buying counterfeit goods. For all the products evaluated, quality and price consistently proved the most important factors driving the intention to buy counterfeits. The implications are highlighted; combating counterfeiting is not an exclusive preserve of any single entity (governments, business or para‐governmental agencies) but a shared responsibility. There is a lot at stake for consumers, manufacturers and the industrial nations if the menace is not effectively checked. Copyright © 2012 John Wiley & Sons, Ltd.
