1. Which of the following describes postconcussion syndrome? • 1. Irritability, fatigue, and headaches. • 2. Loss of consciousness for minutes to an hour. • 3. Loss of consciousness for hours to days. • 4. Headaches and numbness on one side of the body. Feedback: A postconcussion syndrome is characterized by a constellation of somatic and psychological symptoms, the most common of which are irritability, fatigue, headache, and dizziness. Loss of consciousness for minutes to an hour (Response 2) may occur as a result of either a concussion or a contusion (a more severe blow to the head). Loss of consciousness for hours to days (Response 3) describes a coma. Headaches and unilateral numbness (Response 4) can occur after consciousness is regained following a contusion. ETHICAL/LEGAL/PROFESSIONAL ISSUES 2. You are interested in conducting research on cultural values toward older adults in the rural South. Upon consultation with experts in this area you find that asking for written informed consent might alienate some of your research subjects. You should: • 1. go ahead and get written consent anyway, as it is required by the APA Ethics Code. • 2. find another way of ensuring consent and proceed with the research. • 3. find a different population to conduct your research on. • 4. recruit research subjects who are willing to give written consent. Feedback: According to section 3.10 of the APA Ethics Code regarding informed consent, “psychologists [must] appropriately document written or oral consent, permission and assent.” Thus, written consent is not required by the APA Ethics Code and you can find another way of ensuring consent (e.g., oral consent). In this situation, for example, some of your subjects may be illiterate and insisting on written consent might jeopardize your research. GROWTH AND LIFESPAN DEVELOPMENT 3.
