Anxiety,Depression, and Procrastination Among Students: Rumination Plays a Larger Mediating Role than Worry

Procrastination is prevalent among students and is associated with negative outcomes, including poor academic performance and psychological distress. Research also suggests that anxiety and depression can exacerbate procrastination; however, the mechanisms associated with the development of procrastination are less understood. The current study aimed to clarify the role of negative repetitive thought (i.e., rumination and worry) in the links between anxiety and procrastination, and depression and procrastination. Ninety-one undergraduate students completed self-report measures of anxiety, depression, worry, brooding rumination, and procrastination, and two multiple mediator models were tested. Procrastination was positively correlated with the study variables, including medium effects for anxiety and depression, a large effect for rumination, and a small effect for worry. Rumination independently mediated the relationships between anxiety and procrastination, and depression and procrastination. Worry did not independently mediate these relationships. The current findings suggest rumination plays a larger role in the links between anxiety, depression, and procrastination than worry. Thus, students with higher levels of anxiety and depression engage in more negative repetitive thought, which may contribute to procrastinatory behavior as a result of a preoccupation with depressing or painful thoughts about the past.     

Social audiences can disrupt learning by teaching

To investigate the effect of a social audience on learning-by-teaching, we examined participants' solutions of the 4-ring Tower of Hanoi problem after they demonstrated the 3-ring problem to a social agent (a person) or a non-social agent (a computer). In Introduction, Discussion participants produced less optimal solutions of the 4-ring problem after demonstrating the 3-ring problem to a social agent. An analysis of pointing behavior demonstrated that social highlighting contributed substantially to this effect. Together, these findings indicate that more social highlighting may produce a cost, rather than a benefit, on how deeply the demonstrator encodes the problem solution. Experiment 3 clarified that these results were not simply caused by the disruptions inherent to social highlighting. Taken together, the results suggest that social highlighting does not come for free — producing the highlighting may lead to more shallow encoding of demonstrated actions.     

Disability research in counseling psychology journals: a 20-year content analysis

We conducted an exploratory content analysis of disability research in 5 major counseling psychology journals between 1990 and 2010. The goal was to review the counseling psychology literature to better understand the prevalence of disability research, identify research methods most often conducted, and elucidate the types of concerns most studied. We searched 5 journals (Journal of Counseling & Development, Journal of Counseling Psychology, The Counseling Psychologist, Journal of Multicultural Counseling and Development, and Cultural Diversity and Ethnic Minority Psychology) using keywords derived from disability terms defined by the Individuals With Disabilities Education Improvement Act of 2004 (IDEA). Articles were categorized by methodology and disability category examined. We found that disability research continues to comprise an extremely small amount (from less than 1% to 2.7%) of the counseling psychology literature, with the frequency of articles plateauing in recent years. The research design of articles published has changed, with an increased number of empirical articles and a decrease in literature reviews. We conclude by calling for increased empirical investigation of disability among journals specific to counseling psychology to recognize disability as an important aspect of diversity within the field.     

The Confluence of Adverse Early Experience and Puberty on the Cortisol Awakening Response

Associations between early deprivation/neglect in the form of institutional care with the cortisol awakening response (CAR) were examined as a function of pubertal status among 12- and 13-year-old post-institutionalized youth. CARs indexed hypothalamic-pituitary-adrenocortical reactivity. Post-institutionalized youth were compared to youth adopted internationally from foster care (adoption control) and to nonadopted youth reared in families comparable in parental education and income to the adoptive families. Post-institutionalized youth exhibited a blunted CAR if they were at earlier but not if they were at later stages of puberty. Similarly, for both groups of internationally adopted youth combined, earlier but not later stages of puberty were associated with more blunted CARs at higher but not lower levels of parent-reported pre-adoption physical and social neglect.     

Everyday Attention: Variation in Mind Wandering and Memory in a Lecture

Understanding the factors underlying variation in attentional state is critical in a number of domains. Here, we investigate the relation between time on task and mind wandering (i.e., a state of decoupled attention) in the context of a lecture. Lectures are the primary means of knowledge transmission in post secondary education rendering an understanding of attentional variations in lectures a pressing practical concern. We report two experiments wherein participants watched a video recorded lecture either alone (Experiment 1) or in a classroom context (Experiment 2). Participants responded to mind wandering probes at various times in the lecture in an effort to track variations in mind wandering over time. In addition, following the lecture, memory for the lecture material was tested. Results demonstrate that in a lecture mind wandering increases with time on task and memory for the lecture material decreases. In addition, there was a significant relation between mind wandering and memory for lecture material. Theoretical and practical applications of the present results are discussed.

The Suicide (SPI) and Violence Potential Indices (VPI) from the Personality Assessment Inventory: A Preliminary Exploration of Validity in an Outpatient Psychiatric Sample

Assessing risk of harm to self and others is an important component of psychological assessment, although methods for risk assessment vary considerably. The Personality Assessment Inventory (PAI) is frequently administered to evaluate general psychological functioning, as well as to provide information about suicide and violence risk. The purpose of this study was to evaluate the construct validity of the PAI Suicide (SPI) and Violence Potential (VPI) indices in a sample of 158 psychiatric outpatients referred for psychological and neuropsychological assessment within a large northeastern academic medical center between 2007 and 2011. Results generally supported the convergent and divergent validity of both SPI and VPI when evaluating groups with and without a history of suicide and violence risk, and effect sizes were moderate to large even after controlling for other covariates. SPI and VPI scores were also found to vary significantly across different psychiatric groups in ways that would be expected. Finally, we explored the relationship between SPI and VPI, and executive functioning impairment??a neuropsychological variable found to be associated with impulsive self and other-harming behaviors. Consistent with prior research, SPI and VPI were found to be significantly elevated in groups demonstrating executive dysfunction. The implications of these findings and specifically the utility of using SPI and VPI in the assessment of risk are discussed.     

Disease-avoidant behaviour and its consequences

Medical conditions that are non-contagious, but that appear contagious, seem to result in the sufferer being avoided. Error management theory (EMT), suggests that such false alarms occur because the cost of infection poses a greater threat to ones fitness than avoidance. Study 1 attempted to demonstrate a disease-related false alarm effect by asking participants, to evaluate a series of vignettes, featuring people with infectious diseases, non-infectious diseases that looked infectious and non-infectious diseases that did not. Judgements of contracting infection under varying levels of contact, and desire to avoid were obtained. Consistent with EMT, a false alarm effect was evident. Study 2 examined the importance of the face as a key indicator of real and apparent infection, by determining whether facial symptoms result in a greater desire to avoid people with infectious and non-infectious diseases. Consistent with expectation, participants reported a greater desire to avoid people with facially displayed symptoms. Together, these results support the idea that humans have evolved a general tendency to avoid individuals with disease signs, especially if displayed upon the face. One consequence is that where a facially displayed disease sign persists, even if known to be benign, its bearer will experience chronic avoidance.     

"Age of onset of marijuana use and executive function": Correction to Gruber et al. (2011)

Reports an error in "Age of onset of marijuana use and executive function" by Staci A. Gruber, Kelly A. Sagar, Mary Kathryn Dahlgren, Megan Racine and Scott E. Lukas (Psychology of Addictive Behaviors, Advanced Online Publication, Nov 21, 2011, np). Figure 1 should have been presented in color. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2011-27123-001.) Marijuana (MJ) remains the most widely abused illicit substance in the United States, and in recent years, a decline in perceived risk of MJ use has been accompanied by a simultaneous increase in rates of use among adolescents. In this study, the authors hypothesized that chronic MJ smokers would perform cognitive tasks, specifically those that require executive function, more poorly than control subjects and that individuals who started smoking MJ regularly prior to age 16 (early onset) would have more difficulty than those who started after age 16 (late onset). Thirty-four chronic, heavy MJ smokers separated into early and late onset groups, and 28 non-MJ smoking controls completed a battery of neurocognitive measures. As hypothesized, MJ smokers performed more poorly than controls on several measures of executive function. Age of onset analyses revealed that these between-group differences were largely attributed to the early onset group, who were also shown to smoke twice as often and nearly 3 times as much MJ per week relative to the late onset smokers. Age of onset, frequency, and magnitude of MJ use were all shown to impact cognitive performance. Findings suggest that earlier MJ onset is related to poorer cognitive function and increased frequency and magnitude of MJ use relative to later MJ onset. Exposure to MJ during a period of neurodevelopmental vulnerability, such as adolescence, may result in altered brain development and enduring neuropsychological changes.

Explaining the relation between thin ideal internalization and body dissatisfaction among college women: the roles of social comparison and body surveillance

Sociocultural models of disordered eating lack comprehensive explanations as to how thin ideal internalization leads to body dissatisfaction. This study examined two social psychological theories as explanations of this relation, namely social comparison and objectification theories, in a sample of 265 women attending a Southeastern university. Social comparison (both general and appearance-related) and body surveillance (the indicator of objectification) were tested as mediators of the relation between thin ideal internalization and body dissatisfaction using bootstrapping analyses. Results indicated that body surveillance was a significant specific mediator of this relation; however, neither operationalization of social comparison emerged as such. Results serve to elaborate upon the sociocultural model of disordered eating by providing a more comprehensive understanding of the processes by which thin ideal internalization manifests itself in body dissatisfaction. The current findings also highlight the importance of targeting body surveillance in clinical settings.     

Comment: Starting to Solve the Method Puzzle in Salesperson Self-Report Evaluations

In a recent Journal of Personal Selling & Sales Management paper, Jaramillo, Carrillat, and Locander (JCL) further extended our understanding of the errors of salesperson self-report evaluations when compared to managerial evaluations. Our paper provides contrary evidence on three major conclusions drawn in this study. First, we question the assertion by JCL that the correlation between self-report and objective measures of performance is consistently low. Second, we question JCL’s claim that the correlation between managerial evaluations and objective measures of performance is consistently high. Third, we question the key finding of JCL that self-report measures of salesperson performance are less accurate than managerial evaluations. We provide an alternative perspective to these issues by highlighting past research on performance measurement. Moreover, we reanalyze data from a previously published study to examine the issues raised by JCL. Our expectation is that this comment will serve as an impetus for further research in this area.
