Index Of Problematic Online Experiences: Item Characteristics And Correlation With Negative Symptomatology, Kimberly J. Mitchell, Chiara Sabina, David Finkelhor, Melissa Wells
Index Of Problematic Online Experiences: Item Characteristics And Correlation With Negative Symptomatology, Kimberly J. Mitchell, Chiara Sabina, David Finkelhor, Melissa Wells
Psychology
This exploratory study aimed to develop and test a quick, easily administered instrument, the Index of Problematic Online Experiences (I-POE). The goal of the I-POE extends beyond assessing for Internet overuse to broadly assess problematic Internet use across several domains and activities. Data was collected from 563 college students from a Northern New England university using an online survey methodology. Results indicated the I-POE has adequate construct validity and is highly correlated with a variety of relevant constructs: depression, anger=irritability, tension-reduction behavior, sexual concerns, and dysfunctional sexual behavior as measured by the Trauma Symptom Inventory; as well as amount of …
Say Syrah, Syrah: Savoring The Rewards Of Patience, Contemplation, And Tlz, Thomas G. Plante
Say Syrah, Syrah: Savoring The Rewards Of Patience, Contemplation, And Tlz, Thomas G. Plante
Psychology
My family and I fondly say that we have the best syrah Menlo Park has to offer. (Although to our knowledge, it is the only syrah grown in Menlo Park.) While that doesn’t put us in the league of prominent winemaking alumni and friends of Santa Clara—including Michael Mondavi ’66, the Sebastianis, and Fess Parker—it is the result of a decade of growing grapes at our home on the Peninsula.
Cognition And Leisure Time Activities Of Older Adults, Patricia M. Simone, Amie L. Haas
Cognition And Leisure Time Activities Of Older Adults, Patricia M. Simone, Amie L. Haas
Psychology
Older adults have much more leisure time today than they have had in the past. Evidence points to the connection between engagement in physical exercise, a leisure time activity, and the overall health of older adults. Because health is an important issue, especially as we age, it is helpful to know that we have some control over it as we age. Cognition, i.e., our ability to remember, to pay attention, and to think, is also a concern in aging. Is it possible that the choices we make about leisure time activities may influence our cognitive abilities in old age? This …
How Does One Become Spiritual? The Spiritual Modeling Inventory Of Life Environments (Smile), Doug Oman, Carl E. Thoresen, Crystal L. Park, Philip R. Shaver, Ralph W. Hood, Thomas G. Plante
How Does One Become Spiritual? The Spiritual Modeling Inventory Of Life Environments (Smile), Doug Oman, Carl E. Thoresen, Crystal L. Park, Philip R. Shaver, Ralph W. Hood, Thomas G. Plante
Psychology
We report psychometric properties, correlates and underlying theory of the Spiritual Modeling Index of Life Environments (SMILE), a measure of perceptions of spiritual models, defined as everyday and prominent people who have functioned for respondents as exemplars of spiritual qualities, such as compassion, self-control, or faith. Demographic, spiritual, and personality correlates were examined in an ethnically diverse sample of college students from California, Connecticut, and Tennessee (N=1010). A summary measure of model influence was constructed from perceived models within family, school, religious organization, and among prominent individuals from both tradition and media. The SMILE, based on concepts from Bandura's (1986) …
Participation In Prevention Programs For Dating Violence: Beliefs About Relationship Violence And Intention To Participate, Tara L. Cornelius, Kieran T. Sullivan, Nicole Wyngarden, Jennifer Milliken
Participation In Prevention Programs For Dating Violence: Beliefs About Relationship Violence And Intention To Participate, Tara L. Cornelius, Kieran T. Sullivan, Nicole Wyngarden, Jennifer Milliken
Psychology
This study utilizes the Health Belief Model to examine the factors related to the intention to participate in prevention programming for dating violence. Perceptions of susceptibility to future violence and the benefits of prevention programming appear to be the strongest predictors of participation in prevention programs. Perceptions of the severity of dating violence do not appear to be related to intentions to participate. There were no differences in intention between those reporting psychological or physical violence in their dating relationship, although some of the HBM factors were associated with a history of violence. Contrary to hypotheses, psychological and physical violence …
Personal Intelligence Expressed: A Theoretical Analysis, John D. Mayer
Personal Intelligence Expressed: A Theoretical Analysis, John D. Mayer
Psychology
An individual's cumulative life decisions help determine that person's well-being. To make good decisions requires knowing something about who one is and who one wants to be. It seems plausible that personality may draw on a specifically tailored intelligence that supports its own self-understanding and contributes to such life decisions. This personal intelligence (PI) helps the individual meet his or her own personal needs and to fit in with (or stand out from) the environment. What are people high in PI actually like relative to those lower in the skills? Drawing on a 2008 theory of PI-related abilities, the author …

Characteristics Of Spontaneous Musical Imagery, Mike Wammes, Imants Barušs
Characteristics Of Spontaneous Musical Imagery, Mike Wammes, Imants Barušs
Psychology
This study follows upon Steven Brown’s 2006 article in The Journal of Consciousness Studies about the “perpetual music track,” a form of constant musical imagery. With Brown’s assistance, a Musical Imagery Questionnaire was developed and administered to 67 participants with the intention of establishing relevant scales for quantifying the presence and extent of spontaneous musical imagery in individuals. In addition to the Musical Imagery Questionnaire, the Six Factor Personality Questionnaire, as well as the Transliminality Scale, which is a measure of openness to psychological material, was used in order to explore the correlations of spontaneous musical imagery to personality constructs. …
Speculations About The Direct Effects Of Intention On Physical Manifestation, Imants Barušs
Speculations About The Direct Effects Of Intention On Physical Manifestation, Imants Barušs
Psychology
A possible mechanism by which mental acts may be synchronized with physical states is postulated. It is argued that a layer of deep consciousness, similar to David Bohm’s implicate order, underlies and gives rise to both subjective, intentional consciousness and objective, physical manifestation. The influence of volition at the level of intentional consciousness can be conceptualized in the context of the Kochen-Specker theorem as the exercise of the unconstrained choice of observables, and, at the level of deep consciousness, as modulation of the activity of the creation and annihilation operators of a quantum field. The discrete nature of observations …
Head Direction Cell Activity In Mice: Robust Directional Signal Depends On Intact Otolith Organs, R.M. Yoder, J.S. Taube
Head Direction Cell Activity In Mice: Robust Directional Signal Depends On Intact Otolith Organs, R.M. Yoder, J.S. Taube
Psychology
The head direction (HD) cell signal is a representation of an animal's perceived directional heading with respect to its environment. This signal appears to originate in the vestibular system, which includes the semicircular canals and otolith organs. Preliminary studies indicate the semicircular canals provide a necessary component of the HD signal, but involvement of otolithic information in the HD signal has not been tested. The present study was designed to determine the otolithic contribution to the HD signal, as well as to compare HD cell activity of mice with that of rats. HD cell activity in the anterodorsal thalamus was …
Reconciling Findings Of Emotion-Induced Memory Enhancement And Impairment Of Preceding Items, Marisa Knight, M Mather
Reconciling Findings Of Emotion-Induced Memory Enhancement And Impairment Of Preceding Items, Marisa Knight, M Mather
Psychology
A large body of work reveals that people remember emotionally arousing information better than neutral information. However, previous research reveals contradictory effects of emotional events on memory for neutral events that precede or follow them: in some studies emotionally arousing items impair memory for immediately preceding or following items and in others arousing items enhance memory for preceding items. By demonstrating both emotion-induced enhancement and impairment, Experiments 1 and 2 clarified the conditions under which these effects are likely to occur. The results suggest that emotion-induced enhancement is most likely to occur for neutral items that: (1) precede (and so …
Genetic And Environmental Contributions To Body Mass Index: Comparative Analysis Of Monozygotic Twins, Dizygotic Twins And Same-Age Unrelated Siblings, Nancy Segal, R. Feng, Shirley Mcguire, D. Allison, S. Miller
Genetic And Environmental Contributions To Body Mass Index: Comparative Analysis Of Monozygotic Twins, Dizygotic Twins And Same-Age Unrelated Siblings, Nancy Segal, R. Feng, Shirley Mcguire, D. Allison, S. Miller
Psychology
Background—Earlier studies have established that a substantial percentage of variance in obesity-related phenotypes is explained by genetic components. However, only one study has used both virtual twins (VTs) and biological twins and was able to simultaneously estimate additive genetic, non-additive genetic, shared environmental and unshared environmental components in body mass index (BMI). Our current goal was to re-estimate four components of variance in BMI, applying a more rigorous model to biological and virtual multiples with additional data. Virtual multiples share the same family environment, offering unique opportunities to estimate common environmental influence on phenotypes that cannot be separated from …
A Longitudinal Investigation Of The Relationships Amongst Antibody Response To Influenza Vaccination, Affect, And Stress In The Elderly, Joanne Hash-Converse
A Longitudinal Investigation Of The Relationships Amongst Antibody Response To Influenza Vaccination, Affect, And Stress In The Elderly, Joanne Hash-Converse
Psychology
We examined the cross-sectional and longitudinal relationships amongst affect, stress exposure, and antibody (Ab) response to influenza inoculation in a healthy, elderly sample. We explored both efferent (CNS on immune activity) and afferent (immune activity on CNS function) pathways. Negative (NA) and positive (PA) affective states were examined in relation to Ab response, positing that high baseline NA (State, SNA, but not Trait, TNA) would predict reduced Ab response and that PA would predict enhanced response, and that the reduced Ab response in individuals displaying high baseline SNA would associate with decreases in NA. Moderator (for psychogenic and systemic stress) …
Fighting Conflict: Violent Splits Or Healthy Divides?, Katerina Bezrukova, Chester Spell
Fighting Conflict: Violent Splits Or Healthy Divides?, Katerina Bezrukova, Chester Spell
Psychology
In this study, we develop a theory to understand how groups with strong divisions may, paradoxically, help members to cope with conflict and injustice. We test our theoretical predictions using a survey methodology and the data from 72 work groups across different industries. Consistent with our hypotheses, we found that group faultlines weakened the positive relationships between injustice and psychological health.
Transition To Marriage, Tara L. Cornelius, Kieran T. Sullivan
Transition To Marriage, Tara L. Cornelius, Kieran T. Sullivan
Psychology
One of the most sign ificant psychosocial adjustments in adulthood is the transition to marriage. Although most men and women in the United States will marry at some point in their lives and most look forward to this event with anticipation and excitement, the transition to marriage also involves adaptation to a variety of tasks that may fundamentally alter spouses' view of themselves and their alliances.
The Shaping Of A Saint-President: Latent Clues From Nelson Mandela's Autobiography, Abdulrazaq Imam
The Shaping Of A Saint-President: Latent Clues From Nelson Mandela's Autobiography, Abdulrazaq Imam
Psychology
Nelson Mandela's Long Walk to Freedom provides evidence organized in the form of antecedent-behavior-consequence units, which suggest that a shaping process effected during his many years of incarceration best describes the origins of the outcome represented by the political order in South Africa following his release. The analysis shows that Mandela's radicalism at the start of his imprisonment on Robben Island changed into a saintly presidential aura in the end, through a systematic selection process that actively involved Mandela himself and his political aspirations. The saintly qualities ascribed to Mandela after his release by many around the world are consistent …

Behavioral Changes In Aging But Not Young Mice After Neonatal Exposure To The Polybrominated Flame Retardant Decabde, Deborah C. Rice, W. Douglas Thompson, Elizabeth A. Reeve, Kristen D. Onos, Mina Assadollahzadeh, Vincent P. Markowski
Psychology
BACKGROUND: After several decades of commercial use, the flame-retardant chemicals polybrominated diphenyl ethers (PBDEs) and their metabolites are pervasive environmental contaminants and are detected in the human body. Decabrominated diphenyl ether (decaBDE) is currently the only PBDE in production in the United States. oBjectives: Little is known about the health effects of decaBDE. In the present study we examined the effects of neonatal decaBDE exposure on behavior in mice at two ages. METHODS: Neonatal male and female C57BL6/J mice were exposed to a daily oral dose of 0, 6, or 20 mg/kg decaBDE from postnatal days 2 through 15. Two …

In a mouse mutagenesis screen,weisolated a mutant, Myshkin (Myk), with autosomal dominant complex partial and secondarily generalized seizures, a greatly reduced threshold for hippocampal seizures in vitro, posttetanic hyperexcitability of the CA3-CA1 hippocampal pathway, and neuronal degeneration in the hippocampus. Positional cloning and functional analysis revealed that Myk/+ mice carry a mutation (I810N) which renders the normally expressed Na +,K+-. ATPase α3 isoform inactive. Total Na +,K+-ATPase activity was reduced by 42% in Myk/+ brain. The epilepsy in Myk/+ mice and in vitro hyperexcitability could be prevented by delivery of additional copies of wild-type Na+,K+-ATPase α3 by transgenesis, which also …
