Book excerpt: Research on the topic of parent beliefs, or parent cognition, has increased tremendously since the original publication of this volume in 1985. For this revised second edition, the editors sought to reflect some of the new directions that research on parent cognition has taken. By offering a greater variety of topics, it gives evidence of the intellectual concerns that now engage researchers in the field and testifies to the expanding scope of their interests. Although a unique collection because it reflects the diversity that exists among major researchers in the field, it evinces a common theme -- that the ideas parents have regarding their children and themselves as parents have an impact on their actions. This emphasis on parents' ideas shifts the focus on sources of family influence to ideas or beliefs as determinants of family interactions. The implication of this way of thinking for practitioners is that it suggests the shift to ideas and thoughts from behavior and attitudes.
