Fluid Intelligence has Made the Most Gains

So which kinds of intellectual performance have been pushed upward by the better environments of recent decades? Surprisingly, the steepest gains have not been found in the concrete skills that are directly taught in school, such as general knowledge, arithmetic, and vocabulary. They have been found in the abstract, fluid kinds of intelligence, the ones tapped by similarity questions (“What do an hour and a year have in common?”), analogies (“BIRD is to EGG as TREE is to what?”), and ...

 The problem with testing for abstraction

...students learn by doing. Testing for abstraction on an exam can’t be the only way we’re evaluating student learning. If I had taken an exam on leadership in World of Warcraft, I would have likely failed, because the way I was engaged was through the practice of performing the leadership, not by talking or quizzing on it. Thought leader within the game-based learning movement, James Paul Gee, refers to this type of learning as “Situated and Embodied Learning,” where the learning is ...

 Gamification Memory Mechanic

In Memory games, the action of the game has some element that is dependent on players’ memory. This is simple and straightforward enough on its surface, but it becomes interestingly complex when examined in greater detail. What particular parts of memory are being tasked by the game? Some games ask the player to memorize and recall specific details or patterns. Others call on memories that a player brings into the game from his or her actual life. Still other memory games ask players not on...

 Busyness Correlated with Improved Cognitive Performance

Sustained engagement in mentally challenging activities has been shown to improve memory in older adults. We hypothesized that a busy schedule would be a proxy for an engaged lifestyle and would facilitate cognition. Here, we examined the relationship between busyness and cognition in adults aged 50–89. Participants (N = 330) from the Dallas Lifespan Brain Study (DLBS) completed a cognitive battery and the Martin and Park Environmental Demands Questionnaire (MPED), an assessment of busyness...

 The Myth of the Brain as a Video Camera

Before we discuss what current research tells us about memory and recall, it may be helpful to address a common misconception that emerged from the work ofCanadian neurosurgeon Wilder Penfield in the 1930s and 1940s. Penfield reported that during surgery, an electrical stimulation of the temporal lobe produced episodes of recall, almost like seeing movie clips. Many concluded that the brain ―videotaped‖ life, and to remember things, our memories simply needed to be prompted. But these epi...

 Confirmation Bias

Numerous studies have demonstrated that people generally give an excessive amount of value to confirmatory information, that is, to positive or supportive data. The "most likely reason for the excessive influence of confirmatory information is that it is easier to deal with cognitively" (Gilovich 1993). It is much easier to see how a piece of data supports a position than it is to see how it might count against the position. Consider a typical ESP experiment or a seemingly clairvoyant dream: ...
