Day-Night Differences In Neural Activation In Histaminergic And Serotonergic Areas With Putative Projections To The Cerebrospinal Fluid In A Diurnal Brain, Alexandra Castillo-Ruiz, Andrew J. Gall, Laura Smale, Antonio A. Nunez

Faculty Publications

In nocturnal rodents, brain areas that promote wakefulness have a circadian pattern of neural activation that mirrors the sleep/wake cycle, with more neural activation during the active phase than during the rest phase. To investigate whether differences in temporal patterns of neural activity in wake-promoting regions contribute to differences in daily patterns of wakefulness between nocturnal and diurnal species, we assessed Fos expression patterns in the tuberomammillary (TMM), supramammillary (SUM), and raphe nuclei of male grass rats maintained in a 12:12 h light-dark cycle. Day-night profiles of Fos expression were observed in the ventral and dorsal TMM, in the SUM, …

Innovation Exposition: Advanced Research Course In Psychology (Psy 390), John Shaughnessy, Sonja Trent-Brown, Daryl R. Vantongeren

Faculty Presentations

The innovative Advanced Research course was designed in the early 1980s, well before the pedagogical approach of enquiry-based instruction was widely championed in the late 1990s to early 2000s (National Science Educational Standards, 1996; National Research Council, 2000). Enquiry-based instruction entails “learning through doing” and is a method of teaching and learning based on self-directed enquiry (EBL) or research (RBL) by the student (University of Manchester, 2007; University of Reading, n.d.). This course integrates a research experience for students in the psychology curriculum that reflects a cutting edge approach to teaching psychology. The “lone-wolf” model of science is outdated and …

Strengthening The Pathway To Stem Research Leadership At Hope College, Catherine Mader

Faculty Presentations

Over the past 20 years, awards from the Howard Hughes Medical Institute have supported Hope's efforts to conduct STEM research and to prepare students to pursue careers as STEM researchers. The current program is building upon prior successes to create a deliberate pathway for students as they enter Hope as novices, build STEM Researcher skills through coursework and summer research and eventually become student leaders in STEM Research groups.

25 Years Of Psychology Internships, Charlotte Vanoyen-Witvliet, Patricia V. Roehling

Faculty Presentations

Psychology Internships at Hope College are academic semester-long, supervised, pre-professional work experiences related to Psychology and the student's vocational interests. Students pursue agreed upon learning goals in a written learning contract, are supervised on-site, complete weekly assignments, and participate in a class on campus for academic credit.

Lesions Of The Intergeniculate Leaflet Lead To A Reorganization In Circadian Regulation And A Reversal In Masking Responses To Photic Stimuli In The Nile Grass Rat, Andrew J. Gall, Laura Smale, Lily Yan, Antonio A. Nunez

Faculty Publications

Light influences the daily patterning of behavior by entraining circadian rhythms and through its acute effects on activity levels (masking). Mechanisms of entrainment are quite similar across species, but masking can be very different. Specifically, in diurnal species, light generally increases locomotor activity (positive masking), and in nocturnal ones, it generally suppresses it (negative masking). The intergeniculate leaflet (IGL), a subdivision of the lateral geniculate complex, receives direct retinal input and is reciprocally connected with the primary circadian clock, the suprachiasmatic nucleus (SCN). Here, we evaluated the influence of the IGL on masking and the circadian system in a diurnal …

Attachment And 'Hikikomori': A Psychosocial Developmental Model, Alexander Krieg, Jane R. Dickie

Faculty Publications

Background: Hikikomori (acute social withdrawal) is a social issue in Japan that affects both the society and the lives of the individual sufferers.

Aims: This study aims to connect attachment theory and hikikomori by using a culturally sensitive psychosocial developmental model that outlines the various stages of attachment throughout the developmental years.

Method: Twenty–four hikikomori sufferers and 60 comparison group participants were given questionnaires assessing parent and peer relationships, temperament and school experiences.

Results: We found the hikikomori participants had a higher incidence of ambivalent attachment, reported more parental and peer rejection and bullying, and expressed greater temperamental shyness. Path …
