Scenario III
Scenario III is based on fabricated data inspired by the following study:
Duran, J., Morton, G. & Sikorski, A.M. Poster No. 31. Elucidating the relative concentration of physical activity to memory consolidation and memory retrieval. Faculty for Undergraduate Neuroscience Meeting. San Diego, CA: FUN 2010
Exercise and Memory Study
These researchers examined whether acute physical activity could improve the memory retention of recently studied items, and whether memory was differentially affected by the timing of exercise intervention. After studying a list of 40 English-Swahili word pairs, healthy adult human volunteers were randomly assigned to one of three treatment conditions. Participants in the consolidation treatment (CONS) exercised for 20 minutes immediately after studying the word pairs and then worked on a jigsaw puzzle for 20 minutes. Participants in the retrieval condition (RET) worked on a jigsaw puzzle for 20 minutes immediately after studying the word pairs and then exercised for 20 minutes. Participants in the control condition (CONT) worked on a jigsaw puzzle for 40 minutes after studying the word pairs. . In all conditions, participants were tested 40 minutes following the initial study phase. the test phase consisted of presenting the participants with Swahili words and asking them to speak its English translation. Memory was operationally defined by the total number of correctly recalled Swahili words. The results revealed that participants who had exercised immediately after studying the Swahili-English word pairs recalled significantly more words than those in the RET or CONT conditions. These results suggest that acute exercise immediately following learning modulates memory consolidation.
-(Scenario III) Amber was a participant in this study who was tested in the control condition. Her classmate, Jeff, also participated in the study but was tested in the RET condition. After sharing their experiences with each other they determined that the study was probably about college students' ability to learn a foreign language. Amber and Jeff are engaging in:
Risk-adjusted Discount Rates

Unsystematic Risk
The risk associated with a specific company or industry, which can be reduced through diversification.
Diversifiable Risk
A type of investment risk that can be reduced or eliminated through the use of diversification strategies across different assets or asset classes.
Beta
A measure of a stock's volatility in relation to the overall market, indicating its riskiness compared to the market average.
