The present study was designed to test the causal locus hypothesis, and to develop and explore the selfevaluational hypothesis. The causal locus hypothesis is based on attribution, which is a person's perception of cause. The hypothesis holds that persons making internal attributions (self-caused) for failure end external attributions (not self-caused) for success experience more negative postoutcome mood than persons making external attributions for failure and internal attributions for success. The hypothesis was derived from major theories or attribution, but was not experimentally tested until recently (Wollert et al., 1981).

The purpose of the current investigation was to examine the efficacy of a music therapy protocol on mood states and levels of group cohesiveness in adult oncology patients. Eleven oncology patients in two groups (ages 30 to 84 years) took part in the study over a ten-week period of time (ten participants completed the study). During that period, participants took part in eight music therapy sessions consisting of two types of interventions: 1) four "music making" sessions (where the mechanism for change included the process of making music) and 2) four "music responding" sessions (where the mechanism included the process of responding to music). The two types of music therapy sessions and their effectiveness on improving mood states and group cohesiveness were examined. The Profile of Mood States- Short Form (POMS-SF) was used to assess changes in participants' mood states. A content analysis, attendance records, and a questionnaire were used to assess levels of group cohesiveness. Results showed significant improvement in mood state scores (from pre session levels to post sessions levels) after involvement in all music therapy sessions. Similar significant findings were found within each of the "music making" and "music responding" conditions but no differences were found when comparisons were made between those conditions. No statistically significant effects were found with respect to group cohesiveness measures. Study implications and future research directions are discussed.

Previous research on premenstrual tension has typically focused on the hormonal or biological theories of premenstrual tension. Recent research, however, has begun to show a relationship between negative expectancies and reports of premenstrual suffering. In this study it was hypothesized that negative expectancies could be changed by exposing participants to information which either increased or decreased their sense of control over premenstrual symptomatology. It was proposed that information which offered participants a way to control premenstrual symptoms would decrease expectations while information which informed participants that they could not control their symptoms would increase negative expectations. In this study it was further hypothesized that participants exposed to information which decreased their negative expectancies would report more positive moods during the premenstrual phase of the menstrual cycle than those subjects exposed to information which increased their expectations for premenstrual tension. Results from this study supported the hypothesis that expectancies for premenstrual tension are related to the participants' sense of control over premenstrual tension. However, results did not show a relationship between daily reports of mood during the premenstrual phase and negative expectations. / Master of Science

This study investigated the relationship between the depressive attributional style described by Beck and Seligman and elevation of mood. It was proposed that mood elevation would reduce the level of depression and, in addition, would reduce the number of negative attributions. The reduction of negative attributions was assumed to be a more cognitively mediated process and was proposed to occur subsequent to mood change. These assumptions are contrary to the current cognitive theories of depression and attribution which view attributional style as a prerequisite to both the development and reduction of depression. Subjects were 30 undergraduate students between the ages of 19 and 40 years old who volunteered to participate in the study. They were screened on the basis of demonstrated depression (13 and above on the Beck Inventory) and susceptibility to hypnosis (high susceptibility on the Harvard Group Scale of Hypnotic Susceptibility) . Subjects were randcmly assigned to one of three groups; (1) hypnosis with mood elevation, (2) hypnosis with relaxation, and (3) no treatment control. The results supported the hypothesis that mood elevation would reduce level of depression. The mood elevation group demonstrated a lowering of depression. The effects of the treatment procedure did not appear until the fourth session. As anticipated, reduction in negative attributions did not precede or coincide with reduction in depression. It was not possible to determine the change in the attributional style of subject during the time period of this study. The results were discussed in terms of Bower's Associative Network Theory in which activation of mood facilitates the access to memories, behaviors, and interpretation of events which are congruent with the mood state.

To investigate the effects of emotional arousal on information processing strategy, three different moods (sadness, anger, and happiness) were hypnotically induced at three different levels of intensity (high, medium, and low) in 29 male and female undergraduate students, while engaging them in a visual information processing task. Subjects were screened for hypnotic susceptibility and assigned to either a high susceptibility group or low susceptibility group to account for the attentional bias associated with this trait. All subjects were trained to access the three emotions at the three levels of intensity. During separate experimental sessions, subjects were hypnotized, and asked to access a mood and experience each level of intensity while being administered the Navon Design Discrimination Task, a measure of global and analytic visual information processing. Scores were derived for global processing, analytic processing, and a percentage of global to analytic processing for each level of mood and intensity. Two (hypnotic susceptibility) x 3 (emotion) x 3 (intensity level) repeated measures ANOVAs were computed on the global, analytic, and percentage scores. In addition, two separate ANCOVAs were computed on each dependent measure to account for the effects of handedness, and cognitive style. None of these analyses revealed significant main effects or interactions. The analysis of the percentage scores revealed a trend toward differences between the emotions, but in a direction opposite to that hypothesized. Hypnotic susceptibility does not appear to mediate global and analytic responses to the Navon visual information processing task when emotions are being experienced. Results regarding emotions and emotional intensity were discussed in terms of the problems with adequate control and manipulation of mood and intensity level. Difficulties with the Navon measure were also explored with regard to the exposure duration in the Navon task, and its adequacy in measuring shifts in information processing associated with transient mood states. Implications for future research were discussed.

The current study utilized a quasi-experimental nonequivalent groups design to investigate whether a 5-week long Mindfulness Meditation Intervention (MMI), would impact measures of attention, positive and negative affect, state and test anxiety, mindfulness, and reactive cortisol levels in 107 school aged children. A series of reliability corrected ANCOVAs were performed on all behavioral variables. Results indicated that those in the MMI group did not differ from their cohorts on any of the behavioral measures. Reactive levels of salivary cortisol were also collected and assayed in a subsample of 25 participants. An ANCOVA on cortisol change scores was performed and findings did not reach statistical significance. Post-hoc power analyses revealed that this could be due to inadequate sample size. To conclude studies utilizing a MMI of longer duration or with larger sample sizes may be required in assessing the usefulness of MMIs in behavioral and physiological measures in non-clinical child populations. / by Maria L.

Previous research has shown that the intrapersonal characteristics (e.g., temperament) of children are associated closely with alterations in the functioning of the hypothalamic-pituitary–adrenal (HPA) stress axis. However, consistently capturing direct associations between these characteristics and stress reactivity of the HPA axis has, at times, yielded disparate findings. Thus, using the Rothbart model of temperament (Rothbart & Derryberry, 1981) as a guide, the main goal of this project was to investigate and identify intrapersonal characteristics that moderate associations between other intrapersonal characteristics of the child and stress reactivity during development (e.g., trait by trait interactions). Additionally, study variables were assessed for meaningful associations and, on average differences between those who responded to the stressor paradigm and those who did not. A sample of 45 male and 37 female students (n=82, M= 9.66 yrs.) from six, fourth and fifth grade classes partook in a mathematically based stressor paradigm administered in the classroom. Salivary cortisol and behavior measures were collected in two waves over a 7-week period. Several significant results emerged. Overall, children who responded to the stressor paradigm had significantly higher levels of traits associated with a more inhibited behavioral style. Further, several meaningful interactions surfaced in which intrapersonal characteristics of various categories, including reactive, regulatory, and ambiguous, interacted with one another to predict stress reactivity. Of note, the majority of the interactions involved self-regulation and surgency. These two intrapersonal characteristics interacted with several others, helping to elucidate the unique influences of these intrapersonal characteristics on each other and, subsequently, stress reactivity of the HPA axis. These results illustrate that interactions between multiple intrapersonal characteristics should be taken into consideration in the future when studying the relationships between intrapersonal characteristics and stress reactivity of the HPA axis. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Background: Inverse associations have been reported between homocysteine concentrations and poor cognitive performance in several cross-sectional studies of healthy elderly subjects. Folate supplementation with or without vitamins B-12 and B-6 is an effective means of lowering homocysteine concentrations. Mood disturbances, from mild mood changes to clinical depression, are common in older populations. Several studies have shown that depressed people have lower levels of folate and vitamin B-12 and higher levels of homocysteine than non-depressed people. Improvement of mood has been reported in depressed people following supplementation with folic acid. Clinical trials are required to determine if lowering homocysteine concentration with vitamins improves cognitive function and/or mood in healthy elderly participants. Objective: The primary aim of this research project was to carry-out a 2 year randomised, double-blind, placebo-controlled trial to determine if a supplement containing folate (1mg L-Mefolinic acid), vitamin B-12 (500(mu)g) and vitamin B-6 (10mg) improves scores or prevents decline on tests of cognition in a group of healthy older people ([greater than or equal to]̲ 65 years) with a plasma homocysteine concentration [greater than or equal to]̲13 (mu)mol/L. A second aim of this study was to determine if homocysteine lowering vitamins improved scores on tests of mood in this group. Methods: Four hundred and sixty-five individuals, aged 65 and over, were recruited from Dunedin and surrounds, and asked to attend a screening clinic and provide a fasting blood sample. Two-hundred and seventy-six volunteers with a plasma homocysteine concentration [greater than or equal to]13(mu)mol/L were randomised to take either a combination of 1mg L-Mefolinic acid, 500(mu)g vitamin B-12 and 10mg vitamin B-6 or placebo for 2 years. A battery of cognitive tests and indices of mood was administered at baseline, one year, and two years. A fasting blood sample was collected at baseline and every six months thereafter. Results: From baseline to 6 months of the intervention, homocysteine concentrations decreased by 37.5%, from 16.7 to 10.5 (mu)mol/L in the vitamin supplemented group and then plateaued. In the vitamin supplemented group there was a 181% increase in red blood cell folate concentration from a mean of 977 to 2752 nmol/L, and a 90.1% increase in plasma vitamin B-12 (from a mean 283 to 538 (mu)mol/L) over the study period of two years. In the vitamin supplemented group there was a trend to poorer performance on almost all tests of cognition compared to placebo group. The vitamin group was 8% slower on Part B of the Reitan Trail Making Test, a test of speeded attention, mental tracking, visual search and mental flexibility (p=0.009). The vitamin group scored significantly lower on tests of short-term recall, Weschler Paragraphs (p=0.03) after 2 years, and the Rey Auditory Verbal Learning Test ((p=0.04) after one year, than the placebo group. There was no difference in mood score by treatment in this largely non-depressed group. Conclusion: These results suggest a detrimental effect of high dose homocysteine lowering vitamin supplements on cognitive function in healthy older people. These results need to be confirmed in other randomised controlled trials.
