- Recognition memory is defined as the ability to recognize a previously encountered stimulus and has been associated with spatially and temporally distinct event-related potentials (ERPs). Allelic variations of the serotonin transporter gene (SLC6A4) have recently been shown to impact memory performance. Common variants of the serotonin transporter-linked polymorphic region (5HTTLPR) of the SLC6A4 gene result in long (l) and short (s) allelic variants with carriers of the s allele having lowered transcriptional efficiency. Thus, the current study examines the effects polymorphisms of the SLC6A4 gene have on performance and ERP amplitudes commonly associated with recognition memory. Electroencephalogram (EEG), genetic, and behavioral data were collected from sixty participants as they performed an item and source memory recognition task. In both tasks, participants studied and encoded 200 words, which were then mixed with 200 new words during retrieval. Participants were monitored with EEG during the retrieval portion of each memory task. EEG electrodes were grouped into four ROIs, left anterior superior, right anterior superior, left posterior superior, and right posterior superior. ERP mean amplitudes during hits in the item and source memory task were compared to correctly recognizing new items (correct rejections). Results show that s-carriers have decreased mean hit amplitudes in both the right anterior superior ROI 1000-1500. ms post stimulus during the source memory task and the left anterior superior ROI 300-500. ms post stimulus during the item memory task. These results suggest that individual differences due to genetic variation of the serotonin transporter gene influences recognition memory. © 2015 Elsevier Ltd.

Interview with Adriennie Hatten (Class of 1990) and Shelby Cogdell Knox (Class of 1991) by Marina Henke

- Adriennie Hatten ('90) and Shelby Cogdell Knox ('91) both share their path to Bowdoin from East Cleveland. They describe the racism that they experienced on campus, especially in their first years at Bowdoin, and how they struggled to develop a sense of place in what was a campus with so few black students. Both Hatten and Knox were highly involved with the African American Society (AfAm) during their time at the College, and the two women share how central Russwurm was to their Bowdoin experience. They reminisce on various speakers that they brought to campus, including Toni Morrison. Finally, Hatten and Knox reflect on AF/AM/50, and share concerns about both the current state of Russwurm and the recent name change from the African-American Society to the Black Student Union. Finally both women criticize the ways that black alumni are treated by the College, and how they see that embodied in the offerings and verbage of their recent weekend on campus.
Interview with Marnita Eaddie (Class of 1990) by Marina Henke

Access: Open access
- Marnita Eaddie ('90) reminisces about her time at Bowdoin, particularly the transition of moving from her predominantly black hometown of East Cleveland to Brunswick, Maine. She shares how variations in wealth between students showed during her time at Bowdoin, but also how students from a variety of backgrounds managed to come together. She recounts confronting racism on the predominantly white campus, and how she navigated being one of less than fifteen black students in her incoming class. She additionally describes her own commitment to academics during her four years at the College, and how she managed to balance a superb academic record along with holding various part-time jobs during all of her semesters. Eaddie brings up the impact of various tragedies on campus, including the death of student Pamela Herbert (‘90) in the Pan Am Flight 103 terrorist attack. Finally, she explores how her later work in the military contrasted and aligned with her Bowdoin experience.
