Externalizing psychopathology and behavioral disinhibition: working memory mediates signal discriminability and reinforcement moderates response bias in approach-avoidance learning

Research has suggested that reduced working memory capacity plays a key role in disinhibited patterns of behavior associated with externalizing psychopathology. In this study, participants (N = 365) completed 2 versions of a go/no-go mixed-incentive learning task that differed in the relative frequency of monetary rewards and punishments for correct and incorrect active-approach responses, respectively. Using separate structural equation models for conventional (hit and false alarm rates) and signal detection theory (signal discriminability and response bias) performance indices, distinct roles for working memory capacity and changes in payoff structure were found. Specifically, results showed that (a) working memory capacity mediated the effects of externalizing psychopathology on false alarms and discriminability of go versus no-go signals; (b) these effects were not moderated by the relative frequency of monetary rewards and punishments; (c) the relative frequency of monetary rewards and punishments moderated the effects of externalizing psychopathology on hits and response bias for go versus no-go responses; and (d) these effects were not mediated by working memory capacity. The findings implicate distinct roles for reduced working memory capacity and poorly modulated active approach and passive avoidance in the link between externalizing psychopathology and behavioral disinhibition.     

Baby Boomers Mature and Gerontological Counseling Comes of Age

Gerontological counseling is the wave of the profession's future. With the majority of 76 million baby boomers beginning to turn 60 years old in 2006, there will be a great need for preretirement to end‐of‐life counselors. This article focuses on (a) the varied influences of this group on the U.S. and the nation's concerns and (b) theories, models, standards, and competencies for counseling this unique population.     

Personality Development in Emerging and Young Adulthood: A Study of Age Differences

Early adulthood is a time of substantial personality change characterized by large inter‐individual diversity. To investigate the role of age in this diversity, the present study examined whether emerging adults differ from an older group of young adults in their Big Five personality development. By means of multi‐group latent change modelling, two groups of 16‐ to 19‐year‐olds (n = 3555) and 26‐ to 29‐year‐olds (n = 2621) were tracked over the course of four years and compared regarding four aspects of personality change: mean‐level change, rank‐order change, inter‐individual differences in change, and profile change. In addition, age‐differential socialization effects associated with six first‐time life events were investigated. Analyses revealed substantial age differences in all four aspects of change. As expected, emerging adults showed greater change and diversity in change than young adults. However, the six life events had no age‐differential impact on change in single traits and Big Five profiles. Overall, the results indicate that age differences should be considered even in specific life stages to advance the understanding of personality development. © 2018 European Association of Personality Psychology     

Long-term adverse health outcomes of physical workplace violence: a 7-year population-based follow-up study

The aim of the present study was to analyse whether physical workplace violence increases the risk of long-term adverse health outcomes (i.e., high number of visits to the general practitioner, outpatient treatment, hospital admittance, antidepressant use, and/or having a mental disorder). The study was based on representative survey data from 2006 and 2010 (entitled “How are you?”) merged with register data for a 7-year follow-up period (N = 30,812). To examine if physical workplace violence was a predictor of adverse health outcomes, logistic regression models were conducted for the total follow-up period and for each follow-up year with the different outcome measures as the dependent variables. In the follow-up period, individuals who were exposed to physical workplace violence had a higher number of visits to the general practitioner, had more often received outpatient treatment, and had more often been admitted to hospital than their non-exposed counterparts. Moreover, exposed individuals had higher odds of using antidepressants in the last three follow-up years than did non-exposed individuals. The findings call for heightened attention to securing preventive as well as rehabilitative strategies to help victims of physical workplace violence with the aim of avoiding adverse long-term health consequences.     

Heart rate reactivity in HAD and LAD rats during Pavlovian fear conditioning

Recently, we reported that High-Alcohol-Drinking (HAD) rats exhibited selective deficits in active avoidance learning under alcohol-naive conditions, and that administration of moderate doses of alcohol (0.5 and 1.0 g/kg) facilitated learning in these rats (Blankenship et al., 2000; Rorick et al., 2003b). We hypothesized that the deficits resulted from excessive fear in the aversive learning context and that the anxiolytic properties of alcohol may have contributed to the improved learning that was observed after alcohol administration. This hypothesis was supported by a recent study in which prolonged freezing in HAD rats was seen after a classical fear conditioning procedure (Rorick et al., 2003a). To provide additional evidence that HAD rats indeed exhibit behaviors consistent with the expression of increased fear in aversive learning contexts, we employed a Pavlovian fear conditioning task to measure heart rate in HAD and Low-Alcohol-Drinking (LAD) rats. In this study, HAD (HAD-1 and HAD-2) and LAD (LAD-1 and LAD-2) rats were assigned to one of three pre-exposure conditions: Context Only, Context/Tone, or Sequential (Context Only followed by Context/Tone) Pre-Exposure. Following pre-exposure, fear conditioning acquisition and extinction procedures were identical for all groups. Results indicated that although no baseline differences were observed between HAD and LAD rats, HAD rats receiving Context-Only pre-exposure exhibited excessive heart rate reactivity to the tone conditional stimulus during fear conditioning acquisition, compared to LAD rats receiving the same pre-exposure conditions. These findings support the hypothesis that HAD rats exhibit behaviors consistent with increased fear in aversive learning contexts, as measured by autonomic conditioning.     

Cognitive ability and risk for alcoholism: short-term memory capacity and intelligence moderate personality risk for alcohol problems

This study tested the hypothesis that short-term memory (STM) capacity moderates the effect of social deviance on alcohol problems. Personality, cognitive ability, and alcohol use and abuse were assessed in the adult offspring of alcoholics (FHPs; n = 153) and the adult offspring of nonalcoholics (FHNs; n = 150). The results revealed that STM capacity moderated the effect of social deviance on alcohol problems, independent of intelligence. High social deviance and high-STM participants had fewer alcohol problems than did high social deviance and low-STM participants. Intelligence also moderated the effect of social deviance on alcohol problems in the same way, independent of STM capacity. FHPs had lower IQs, lower verbal ability, and more response perseveration than FHNs. The results suggest that working memory capacity moderates the risk for alcoholism associated with disinhibited traits.     

Psychological testing and psychological assessment. A review of evidence and issues

This article summarizes evidence and issues associated with psychological assessment. Data from more than 125 meta-analyses on test validity and 800 samples examining multimethod assessment suggest 4 general conclusions: (a) Psychological test validity is strong and compelling, (b) psychological test validity is comparable to medical test validity, (c) distinct assessment methods provide unique sources of information, and (d) clinicians who rely exclusively on interviews are prone to incomplete understandings. Following principles for optimal nomothetic research, the authors suggest that a multimethod assessment battery provides a structured means for skilled clinicians to maximize the validity of individualized assessments. Future investigations should move beyond an examination of test scales to focus more on the role of psychologists who use tests as helpful tools to furnish patients and referral sources with professional consultation.     

Ethics and Phishing Experiments

Phishing is a fraudulent form of email that solicits personal or financial information from the recipient, such as a password, username, or social security or bank account number. The scammer may use the illicitly obtained information to steal the victim’s money or identity or sell the information to another party. The direct costs of phishing on consumers are exceptionally high and have risen substantially over the past 12 years. Phishing experiments that simulate real world conditions can provide cybersecurity experts with valuable knowledge they can use to develop effective countermeasures and prevent people from being duped by phishing emails. Although these experiments contravene widely accepted informed consent requirements and involve deception, we argue that they can be conducted ethically if risks are minimized, confidentiality and privacy are protected, potential participants have an opportunity to opt out of the research before it begins, and human subjects are debriefed after their participation ends.     

Consulting Legal Experts in the Real and Virtual World: Pimps’ and Johns’ Cultural Schemas about Strategies to Avoid Arrest and Conviction

This study addressed the cultural schemas about legal issues associated with on line solicited prostitution from those embedded in the subculture. Qualitative analysis of conversations in a specialized legal website forum, coupled with interview data from 43 pimps, revealed that participants held similar realistic cultural schemas of law enforcement’s priorities and operations, and risk reduction strategies. Evasive strategies emphasized the importance of covert communication in interactions and the use of trustworthy connections (virtual verification websites and non-traceable technology) when engaging in on-line solicited prostitution. Findings have direct implication for strategies aimed at ending demand by targeting johns and pimps.
