Les théories implicites de l’intelligence : une question de perspectives ?

IntroductionImplicit theories of intelligence are beliefs that people form regarding the malleability of intelligence. The so-called “growth” and “fixed” mindsets respectively view intelligence as a characteristic that can or cannot be changed. Psychology, as a science, also offers diverging responses. The developmental and differential traditions in the study of intelligence merely provide different answers because they do not focus on the same sources of variability nor on the same dimensions of intelligence.ObjectivesThe research question that guided the present studies was: Are people's naïve theories influenced by the same factors that drive developmental and differential psychologists to different conclusions?MethodIn Study 1, we first assessed participants’ (n = 509) reference norm orientation (i.e. whether they tend to focus on individual or social comparison), using a task in which they had to predict the school results of an hypothetical child. Then we administered a French version of Dweck's (2007) mindset scale. In study 2, we first asked participants (n = 530) to choose between two definitions of intelligence focusing either on its fluid or crystalized dimensions. Then we administered the French Mindset Scale and asked participants to justify their conclusion.ResultsBoth variables of interest (reference norm orientation and preferred definition of intelligence) had a significant effect on the participant's incremental beliefs.ConclusionThe results of the two studies as well as the qualitative analysis of participants’ arguments suggest that mindsets, like scientific theories, partly stem from the fact that the same question regarding intelligence malleability can be approached with two different perspectives.     

Children's response to sales promotions and their impact on purchase behavior

Despite the growth in children's purchasing power, surprisingly little is known about how children respond to sales promotions. We conduct two experiments to address this issue. Study 1 shows that elementary-aged (second and fifth grade) children's purchase decisions are influenced by the presence of sales. Study 2 demonstrates that both age groups favor conceptually easier promotions, even when the sale is inferior. Additionally, we find that children have difficulty applying mathematical concepts to sales promotions, regardless of classroom mastery of the associated operations. Together, these results indicate that elementary-aged children routinely incorporate sales into purchase decisions, sometimes with suboptimal results.     

Simulating demand for cigarettes among pregnant women: A Low‐Risk method for studying vulnerable populations

A substantive obstacle to experimentally studying cigarette smoking and use of other tobacco products in pregnant women is the risk of adverse effects on mother and fetus from experimenter administration of the product of interest. The purpose of this study is to investigate bypassing that obstacle by using behavioral economic simulation tasks. In the present study we used the Cigarette Purchase Task (CPT) to simulate changes in demand for hypothetical cigarettes as a function of varying cigarette prices. Participants were 95 pregnant women who completed the CPT prior to participation in a smoking‐cessation trial. Aggregate and individual participant demand varied as an orderly function of price and those changes were well fitted by an exponential equation. Demand also varied in correspondence to two well‐validated predictors of individual differences in smoking cessation among pregnant women (cigarettes smoked per day, pre‐pregnancy quit attempts). Moreover, CPT indices were more effective than these two conventional variables in predicting individual differences in whether women made a quit attempt during the current pregnancy. Overall, these results represent a promising step in demonstrating the validity and utility of the CPT for experimentally examining demand for cigarettes, and potentially other tobacco and nicotine delivery products, among pregnant women.     

Expanding the moral circle: Inclusion and exclusion mindsets and the circle of moral regard

The human tendency to draw boundaries is pervasive. The ‘moral circle’ is the boundary drawn around those entities in the world deemed worthy of moral consideration. Three studies demonstrate that the size of the moral circle is influenced by a decision framing effect: the inclusion-exclusion discrepancy. Participants who decided which entities to exclude from the circle (exclusion mindset) generated larger moral circles than those who decided which to include (inclusion mindset). Further, people in an exclusion mindset showed “spill-over” effects into subsequent moral judgments, rating various outgroups as more worthy of moral treatment. The size of the moral circle mediated the effects of mindset on subsequent moral judgment. These studies offer an important first demonstration that decision framing effects have substantial consequences for the moral circle and related moral judgments.     

Stereotype threat affects the learning of sport motor skills

Studies have shown that stereotypical conditions can affect the performance of academic as well as motor skills (for a review see Chalabaev, Sarrazin, Fontayne, Boiché, & Clément-Guillotin, 2013). The objective of the present study was to investigate the influence of stereotype threat on the learning of a sport skill in women. Participants practiced 15 trials of a soccer dribbling task, and their learning was observed in immediate and delayed retention tests. Before practice, participants were divided into two groups which received instructions introducing the task as either involving athletic speed/power capacities, where women normally perform worse than men (stereotypical condition – ST), or as involving agility/coordination capacities, where women normally can perform similarly than men (nullified-stereotype condition – NST). They also filled out questionnaires measuring self-efficacy. Participants of the ST group showed significant lower motor performance and learning, as well as lower self-efficacy levels, than the NST group. The findings provide evidence that the learning of sport skills can be affected by stereotypical conditions. They add to the growing evidence of the impact of social-cognitive and affective factors on motor skill learning.     

Mindsets and pre-conscious open-mindedness to incidental information

Mindset theory (Gollwitzer, 1990) proposes that deliberative mindsets are marked by more open-minded processing of information, whereas implemental mindsets are characterized by more closed-minded processing. Accordingly, deliberative and implemental mindsets should differ in selective processing of incidental information when performing a central task. In three experiments, participants in deliberative and implemental mindsets performed a computer task while randomly presented incidental, unavoidable words. A subsequent recognition memory test assessed selective processing of these incidental words. Results revealed that deliberative mindsets led to superior recognition memory, suggesting increased open-mindedness to processing incidental information. Implications for mindset and goal theories are discussed.
