The impact of personal relevance on emotion processing: evidence from event-related potentials and pupillary responses.

Emotional stimuli attract attention and lead to increased activity in the visual cortex. The present study investigated the impact of personal relevance on emotion processing by presenting emotional words within sentences that referred to participants' significant others or to unknown agents. In event-related potentials, personal relevance increased visual cortex activity within 100 ms after stimulus onset and the amplitudes of the Late Positive Complex (LPC).

The development of reasoning about the temporal and causal relations among past, present, and future events.

Children's capacity to reason about temporal and causal relations among past, present, and future events was investigated. In two studies, 4- and 6-year-olds (N=160) received structurally analogous search and planning tasks that required retrospective or prospective temporal-causal reasoning, respectively. The search task was compared with a closely matched control task that did not require temporal-causal reasoning.
