Since alphanumeric symbols have a known upright position, people have an easier
time being able to picture them in a mental rotation

Chapter eight visual imagery and spatial cognition.  relational-organizational hypothesis: imagery did not improve memory because images are more rich than verbal labels, but imagery produces more associations between items to be memorized.  similar experiments as shepard and metzler (1971),but with letters.  findings: since alphanumeric symbols have a known upright position, people have an easier time being able to picture them in a mental rotation.  findings: people mentally rotate the stimulus in its entirety.  findings: www. notesolution. com: mental rotations are continuous. I maginal scanning: process of forming a visual image and then scanning it.  tacit knowledge: underlying and implicit knowledge about a task.  demand characteristics: the task demands that participant behave in a certain way.  experimenter expectancy effects: experimenter implicitly/explicitly hints for participant to perform by relying on their beliefs.  spatial cognition: how people represent and navigate in and through space.
