Geometry Versus Drawing: Changing the Meaning of the Task as a Means to Change Performance

There is now much convincing evidence that the context in which children are given cognitive tasks can have a huge effect on their performance in those tasks, even when the experimental and control conditions make exactly the same logical and cognitive demands. According to this, we found that children faced with a cognitive-perceptual task (the Rey–Osterrieth's complex figure reproduction test) performed better or worse in one context (geometry) than in another (drawing), depending on their performance history in these contexts, although the task was the same in both conditions. These effects are discussed both in relation to underlying processes and in perspective with another phenomenon (stereotype threat) which also provides evidence for the social regulation of cognitive functioning in the school environment. This revised version was published online in August 2006 with corrections to the Cover Date.     

Sticking to the Evidence? A Behavioral and Computational Case Study of Micro‐Theory Change in the Domain of Magnetism

Constructing an intuitive theory from data confronts learners with a “chicken‐and‐egg” problem: The laws can only be expressed in terms of the theory's core concepts, but these concepts are only meaningful in terms of the role they play in the theory's laws; how can a learner discover appropriate concepts and laws simultaneously, knowing neither to begin with? We explore how children can solve this chicken‐and‐egg problem in the domain of magnetism, drawing on perspectives from computational modeling and behavioral experiments. We present 4‐ and 5‐year‐olds with two different simplified magnet‐learning tasks. Children appropriately constrain their beliefs to two hypotheses following ambiguous but informative evidence. Following a critical intervention, they learn the correct theory. In the second study, children infer the correct number of categories given no information about the possible causal laws. Children's hypotheses in these tasks are explained as rational inferences within a Bayesian computational framework.     

“Lights on at the end of the party”: Are lads’ mags mainstreaming dangerous sexism?

Research has suggested that some magazines targeted at young men –lads’ mags– are normalizing extreme sexist views by presenting those views in a mainstream context. Consistent with this view, young men in Study 1 (n = 90) identified more with derogatory quotes about women drawn from recent lads’ mags, and from interviews with convicted rapists, when those quotes were attributed to lads’ mags, than when they were attributed to convicted rapists. In Study 2, 40 young women and men could not reliably judge the source of those same quotes. While these participants sometimes voiced the belief that the content of lads’ mags was ‘normal’ while rapists’ talk was ‘extreme’, they categorized quotes from both sources as derogatory with equal frequency. Jointly, the two studies show an overlap in the content of convicted rapists’ talk and the contents of contemporary lads’ mags, and suggest that the framing of such content within lads’ mags may normalize it for young men.     

The association between past and future oriented thinking: Evidence from autism spectrum disorder

A number of recently developed theories (e.g., the constructive episodic simulation, self-projection, and scene construction hypotheses) propose that the ability to simulate possible future events (sometimes referred to as episodic future thinking, prospection, or foresight) depends on the same neurocognitive system that is implicated in the recall of past events (episodic memory). In this paper, we argue that autism spectrum disorder (ASD) offers an ideal test of such theories, given that it is a developmental disorder that is characterized by impairments in episodic memory. Each of these theories would predict concomitant impairments in episodic future thinking among individuals with ASD. We review evidence concerning episodic future thinking in ASD, as well as studies of prospective memory (remembering to do something in the future), planning, navigation, and theory of mind, which some theories suggest also rely on the same mechanism as episodic future thinking.     

Dreaming without REM sleep

To test whether mental activities collected from non-REM sleep are influenced by REM sleep, we suppressed REM sleep using clomipramine 50mg (an antidepressant) or placebo in the evening, in a double blind cross-over design, in 11 healthy young men. Subjects were awakened every hour and asked about their mental activity. The marked (81%, range 39-98%) REM-sleep suppression induced by clomipramine did not substantially affect any aspects of dream recall (report length, complexity, bizarreness, pleasantness and self-perception of dream or thought-like mentation). Since long, complex and bizarre dreams persist even after suppressing REM sleep either partially or totally, it suggests that the generation of mental activity during sleep is independent of sleep stage.     

Uncovering hockey fans' motivations behind their derogatory behaviors and how these motives predict psychological well-being and quality of social identity

ObjectiveThis article tested whether hockey fans' selfdetermined and non self-determined motivation for engaging in derogatory behaviors against an outgroup team predicted the frequency of these behaviors, fans' psychological well-being, and the quality of their social identity as a fan of their team. The two psychological theories we employ in the current research (i.e., self-determination theory and social identity theory) have different assumptions concerning the motivation behind derogatory fan behavior.DesignThree correlational studies were conducted among hockey fans.MethodsFans of rival hockey fans (Study 1; N = 45), fans of the Montreal Canadiens (Study 2; N = 181), and fans of NHL teams (Study 3; N = 105) completed measures of selfdetermination to engage in derogatory behaviors, frequency of these behaviors, psychological well-being, and quality of social identity. Multiple regression analyses were conducted to test if the frequency, well-being, and quality of social identity variables were predicted by the self-determined and non self-determined motivations to engage in derogatory behaviors.ResultsAs expected based on self-determination theory (SDT), the more hockey fans engage in derogatory behaviors for non self-determined reasons, the lower their well-being and the less frequently they report engaging in the derogatory behaviors. Moreover, as expected based on social identity theory (SIT), the more hockey fans engage in the derogatory behaviors for self-determined reasons, the higher their well-being, the frequency of these behaviors, and the more positive their social identity.ConclusionsTheses results are interpreted in light of SDT and SIT's theoretical propositions. Comparisons are made with prior studies conducted on this topic.
