New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    The real relationship, therapist immediacy, and client experiencing level: A dyad study of psychotherapy process and connection.
    (2013) Walden, Tamara Tashiko; Gelso, Charles J; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The present study examined the strength of the real relationship (RR) in relation to session quality, therapist immediacy (T-IMM), and client experiencing level (C-EXP) in six psychotherapy dyads over the course of time-limited treatment. Six clients and three therapists completed measures of RR and session quality immediately after each session. Trained judges rated the amount, appropriateness, depth, quality and resolution of T-IMM and the peak and mode level of C-EXP using audio recordings and transcripts post-treatment. This study used the Actor Partner Interdependence Model (APIM; Kenny & Cook, 1999), Structural Equation Modeling (SEM), and Hierarchical Linear Modeling (HLM) to analyze the data due to nesting and interdepence. No significant associations were detected between therapist or client ratings of RR and session quality, between therapist ratings of RR and T-IMM, or between therapist or client ratings of RR and C-EXP. Client perceptions of RR were significantly related to T-IMM rating dimensions, though not significantly related to T-IMM amount or occurrence. The results indicate that regardless of the amount, when therapist immediacy is used appropriately, with depth, quality or resolution, clients perceive stronger real relationships with their therapists. Implications for practitioners and researchers regarding the findings are discussed. In addition, due to the unique racial/ethnic minority (REM) composition of the majority of the dyads, cultural implications for research and practice are considered.

    The influence of fitness on age-related changes in cortical activation associated with cognitive function
    (2004-01-08) Walden, Tamara Tashiko; Hatfield, Bradley; Kinesiology
    Brain function generally declines with age after the fifth decade. EEG Studies generally report that low- frequency EEG activity decreases with age while high-frequency EEG increases, the latter possibly for compensatory reasons. Because exercise has been reported to improve brain neurobiology such as cerebral metabolism and neurotransmitter function, it was expected that exercise would attenuate the age-related changes in EEG activity. Participants were men and women aged 18-35 and 60-75 years that were screened on health and indexed on the basis of physical fitness. Continuous EEG was recorded during each of four cognitive task conditions (eyes-closed, eyes-open, analytical, and spatial) using standardized electrode placements (Fz, Pz, Cz, O1, O2, C3, C4, T3, and T4) and referenced to the average of two ear electrodes (A1 and A2). To examine the relationship of physical fitness, age, and task to spectral power, multivariate analyses of variance were employed (2 x 3 x 2 x 9; Age x Fitness x Task x Site). It was predicted that both young and old participants would have a positive relationship between fitness and low-frequency power. However, the elderly group alone was expected to have a negative relationship between fitness and high-frequency power. Results of the study indicated that aging was associated with substantial changes in cortical dynamics. Furthermore, although the elderly brain appeared to be working in a more effortful manner, fitness did not seem to substantially alter cortical dynamics in relation to fitness level.
