It's the algorithm! Why differential rates of chronicity and comorbidity are not evidence for the validity of the abuse–dependence distinction.

The validity of the abuse–dependence distinction within alcohol use disorders (AUDs) has been increasingly questioned on psychometric and conceptual grounds. Two types of findings are often cited as support for the validity of this distinction: (a) Dependence is more persistent than abuse, and (b) dependence is more highly comorbid with other Axis I and Axis II disorders than is abuse. Using data from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), we examined the extent to which the current diagnostic algorithm (3 of 7 dependence criteria for a diagnosis of dependence; 1 of 4 abuse criteria for a diagnosis of abuse if dependence criteria are not met) produces this pattern of findings independent of item set. Analyses in which all 330 permutations of the 11 AUD criteria were partitioned into a 4-item abuse set and a 7-item dependence set were conducted to examine the relevance of the criteria sets to estimates of persistence and comorbidity independent of criteria. Regardless of the criteria used, the dependence set (i.e., 3/7 criteria) always and substantially outperformed the abuse set (1/4) with respect to both persistence and comorbidity. These data indicate that chronicity and comorbidity are flawed indicators for the abuse–dependence distinction (and likely other conditions in which hierarchical decision rules are used). In addition, our analyses show that the current set of criteria defining alcohol dependence and abuse are not optimal. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

But is it good for the psychologists? Appraisal and status of DSM-III.

Presents a critical analysis of the 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III). Improvements over DSM-II are acknowledged; it is suggested, however, that problems with larger issues (e.g., multiaxial, diagnosis, operational criteria, and the medical model) overshadow these positive features.

Why does the public cooperate with law enforcement? The influence of the purposes and targets of policing.

This study addresses the extension of the “procedural justice” model for understanding public cooperation with law enforcement to new policing contexts and new minority populations. The study draws on four recent surveys of public reactions to policing against crime or against terrorism across different populations to examine whether the changing purpose of policing, or changes in the communities targeted for heightened policing, have an effect on how cooperative behaviors are elicited. This paper presents evidence that procedural justice mechanisms are robust across a variety of contexts and populations in the United States. Three issues in particular are addressed. First, whether the procedural justice model applies across policing functions and policed populations. Second, whether the perception that another group is the target of disproportionate policing efforts has any effect on the cooperation behavior of a non-targeted population. And third, whether people attend to different aspects of policing behavior if their community is targeted for heightened policing attention.

Distinguishing common and task-specific processes in word identification: A matter of some moment?

The same 500 words were presented in 6 different word identification tasks (Experiment 1: lexical decision, semantic categorization, and 3 speeded naming tasks; Experiment 2: delayed naming). Reaction time (RT distributions were estimated for each task and analyses tested for the effects of word frequency and animacy on various parameters of the RT distribution. Low frequency words yielded more skewed distributions than high frequency words in all tasks except delayed naming. The differential skew was most marked for tasks that required lexical discrimination. The semantic categorization task yielded highly skewed distributions for all words, but the word frequency effect was due to shifts in the location of the RT distributions rather than changes in skew. The results are used to evaluate the relative contributions of a common lexical access process and task-specific processes to performance in lexical discrimination and naming tasks.

The mediating role of extreme peer orientation in the relationships between adolescent–parent relationship and diabetes management.

The study examined whether the quality of the adolescent–parent relationship was associated with better diabetes management in adolescents with Type 1 diabetes by decreasing adolescents' extreme peer orientation. Adolescents (n = 252; 46% male and 54% female) aged 10 to 14 years with Type 1 diabetes completed assessments of extreme peer orientation (i.e., tendency to ignore parental advice and diabetes care to fit in with friends), adolescent–parental relationship, and adherence; HbA1c scores indexed metabolic control. Adolescents with higher quality relationships with parents reported less peer orientation and better diabetes care. The mediational model revealed that adolescents' high quality relationships with their parents (mother and father) were associated with better treatment adherence and metabolic control through less peer orientation. It is likely that high quality adolescent–parent relationships may be beneficial to adolescent diabetes management through a healthy balance between peer and parental influence.

Why we respond faster to the self than to others? An implicit positive association theory of self-advantage during implicit face recognition.

Human adults usually respond faster to their own faces rather than to those of others. We tested the hypothesis that an implicit positive association (IPA) with self mediates self-advantage in face recognition through 4 experiments. Using a self-concept threat (SCT) priming that associated the self with negative personal traits and led to a weakened IPA with self, we found that self-face advantage in an implicit face-recognition task that required identification of face orientation was eliminated by the SCT priming. Moreover, the SCT effect on self-face recognition was evident only with the left-hand responses. Furthermore, the SCT effect on self-face recognition was observed in both Chinese and American participants. Our findings support the IPA hypothesis that defines a social cognitive mechanism of self-advantage in face recognition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Feeling recovered and thinking about the good sides of one’s work.

Consistent with a positive psychology perspective, this longitudinal study investigated relations between positive and negative nonwork experiences (i.e., feeling recovered, thinking about the positive and negative aspects of one’s work during leisure time) with different job performance dimensions. In total, 358 employees working with persons with special needs responded to two questionnaires at an interval of 6 months. Results from hierarchical regression analyses showed that feeling recovered during leisure time predicted an increase in task performance after 6 months. This relation was mediated by occupational self-efficacy. Positive work reflection was found to predict an increase in proactive behavior (personal initiative, creativity) and organizational citizenship behavior. Negative work reflection was unrelated to job performance. Our results emphasize the role of positive nonwork experiences for employees’ job performance.

Are impulsive adolescents differentially influenced by the good and bad of neighborhood and family?

Using the differential susceptibility perspective (Belsky & Pluess, 2009) as a guiding frame-work, age 12 neighborhood disadvantage (ND) and family characteristics (parental knowledge) were examined as moderators of the relations between age 12 youth impulsivity and the development (ages 13, 14, and 15) of positive (community activities) and negative (antisocial behavior; ASB) adolescent behavior. An interaction between ND and youth impulsivity (age 12) operated with differential susceptibility, but only for female community activities at age 13: under low levels of ND, impulsive adolescent females engaged in the highest levels of community activities, whereas under high ND, they engaged in the lowest levels. Exploratory analysis showed the association between community activities and ND to be partially related to parents' or adults' engagement in informal social controls (e.g., alerting the police with misbehavior in the neighborhood). Differential susceptibility effects were not identified for: (i) parental knowledge and impulsivity; (ii) ASB (ages 13, 14 or 15); or (iii) community involvement at ages 14 and 15. Findings provide limited evidence for impulsivity as a differential susceptibility phenotype. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

What are the benefits of mindfulness? A practice review of psychotherapy-related research.

Research suggests that mindfulness practices offer psychotherapists a way to positively affect aspects of therapy that account for successful treatment. This paper provides psychotherapists with a synthesis of the empirically supported advantages of mindfulness. Definitions of mindfulness and evidence-based interpersonal, affective, and intrapersonal benefits of mindfulness are presented. Research on therapists who meditate and client outcomes of therapists who meditate are reviewed. Implications for practice, research, and training are discussed.

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance.

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital–firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

An investigation of the effects of time and involvement in the relationship between stressors and work–family conflict.

Previous researchers have proposed that the time and energy involved in family and paid work should affect the relationship between stressors and conflict in both the work and family domains. Using a sample of 113 registered nurses, the authors hypothesized that the amount of time and involvement in both domains would moderate the stressor–conflict relationships. Results supported many of the interactions in predicting conflict in each domain, and implications for the health of working women with family responsibilities were discussed.

What is moral about guilt? Acting “prosocially” at the disadvantage of others.

For centuries economists and psychologists have argued that the morality of moral emotions lies in the fact that they stimulate prosocial behavior and benefit others in a person's social environment. Many studies have shown that guilt, arguably the most exemplary moral emotion, indeed motivates prosocial behavior in dyadic social dilemma situations. When multiple persons are involved, however, the moral and prosocial nature of this emotion can be questioned. The present article shows how guilt can have beneficial effects for the victim of one's actions but also disadvantageous effects for other people in the social environment. A series of experiments, with various emotion inductions and dependent measures, all reveal that guilt motivates prosocial behavior toward the victim at the expense of others around—but not at the expense of oneself. These findings illustrate that a thorough understanding of the functioning of emotions is necessary to understand their moral nature.

Activation of the plant plasma membrane H+-ATPase. Is there a direct interaction between lysophosphatidylcholine and the C-terminal part of the enzyme?

During the period 1978 to 1994, 1054 patients with Hodgkins's disease were evaluated and treated at the Departments of Radiation Oncology and Hematology, University "La Sapienza", Rome. A total of 549 patients presented with clinical or pathological stage I and II; 37 of these had Hodgkin's disease below the diaphragm (BDHD), and 512 above the diaphragm (ADHD). A comparison of patients with BDHD versus those with ADHD showed that the first group had a higher male to female ratio. A comparison of cases with stage II BDHD versus those with stage II ADHD showed that patients with BDHD were older (48 years vs 28 years), had different histologic features and a higher incidence of systematic symptoms (67% vs 33%). Stage II BDHD patients had a worse prognosis; in fact, there were significant differences in the overall survival and relapse-free-survival rates for cases with stage II BDHD versus those with stage II ADHD (overall survival, 46% vs 80%, P<0.001; relapse-free survival, 44% vs 69%, P<0.005). Stage was found to be the most important prognostic factor for BDHD cases without systematic symptoms treated with radiation therapy alone. The type of infradiaphragmatic presentation (intra-abdominal vs peripheral disease) did not influence outcome, probably due to the more aggressive therapy received by the intra-abdominal group. Treatment recommendations for BDHD cases should be tailored to the stage and the presence or absence of intra-abdominal localization. For patients with stage IA extended fields, irradiation (inverted Y) is sufficient. However, combined modality therapy should be the treatment of choice for stage II cases, particularly in the presence of intra-abdominal disease. Patients with systematic symptoms also require combined modalities.     

Relationship between preschool teachers’ reports of children’s behavior and their behavior toward those children.

The relationships between preschool children and their teachers are an important component of the quality of the preschool experience. This study used attribution theory as a framework to better understand these relationships, examining the connection between teachers’ perceptions of children’s behavior and teachers’ behavior toward those children. One hundred seven preschool children and 24 preschool teachers participated in this study. Two teachers reported on each child’s behavior using the Teacher Report Form of the Child Behavior Checklist. Commands and praise directed toward children by the teachers in the study were coded from classroom videotapes. Teachers gave more commands to children that they perceived as having greater general behavior problems, even after controlling for the shared variance in the other classroom teacher’s report of the child’s behavior. Implications for school psychologists, teachers, and researchers are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What is the connection between true and false memories? The differential roles of interitem associations in recall and recognition.

Veridical memory for presented list words and false memory for nonpresented but related items were tested using the Deese/Roediger and McDermott paradigm. The strength and density of preexisting connections among the list words, and from the list words to the critical items, were manipulated. The likelihood of producing false memories in free recall varied with the strength of connections from the list words to the critical items but was inversely related to the density of the interconnections among the list words. In contrast, veridical recall of list words was positively related to the density of the interconnections. A final recognition test showed that both false and veridical memories were more likely when the list words were more densely interconnected. The results are discussed in terms of an associative model of memory, Processing Implicit and Explicit Representations (PIER 2) that describes the influence of implicitly activated preexisting information on memory performance.

Beyond the birds and the bees and was it good for you?: Thirty years of research on sexual communication.

Sexual experience and expression is of fundamental importance to most people. However, most people do not communicate effectively about sexuality even when it is important to do so. For example, many parents see it as their responsibility to talk to their children about sexuality and yet do not engage in in-depth discussions with their children about sexual topics. Most romantic partners have difficulty telling each other what pleases and displeases them sexually. Many health care professionals do not meet their patients' needs for information about the sexual changes they experience as a result of their disease or treatment. Many psychologists also are not doing a good job of addressing sexuality in the classroom, in practicum and internship settings, and/or with clients. These instances of poor sexual communication are unfortunate as effective sexual communication can have a range of positive outcomes such as more satisfying relationships and positive sexual health and well-being over the life span. This paper reviews sexual communication in all of these contexts, focusing on findings from my program of research spanning more than 30 years.

How does cognitive control reduce anger and aggression? The role of conflict monitoring and forgiveness processes.

It is well-established that superior cognitive control abilities are associated with lower levels of anger and aggression. However, the precise emotion regulation operations underlying this relationship have been underspecified and underexplored in previous research. Drawing on neuropsychological models of cognitive control, the authors propose that limited capacity resources can be recruited within a hostile situation to promote a process of forgiveness. The results of 2 studies supported this proposal. Across studies, individual differences in hostility-primed cognitive control were assessed implicitly. In Study 1, hostility-primed cognitive control predicted less aggressive behavior in response to a laboratory provocation. Moreover, forgiveness mediated these effects. In Study 2, hostility-primed cognitive control predicted forgiveness of provocations in participants' daily lives and subsequent reductions in anger. In sum, the results contribute to a systematic understanding of how cognitive control leads to lower levels of anger and aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do others judge us as harshly as we think? Overestimating the impact of our failures, shortcomings, and mishaps.

When people suffer an embarrassing blunder, social mishap, or public failure, they often feel that their image has been severely tarnished in the eyes of others. Four studies demonstrate that these fears are commonly exaggerated. Actors who imagined committing one of several social blunders (Study 1), who experienced a public intellectual failure (Studies 2 and 3), or who were described in an embarrassing way (Study 4) anticipated being judged more harshly by others than they actually were. These exaggerated fears were produced, in part, by the actors' tendency to be inordinately focused on their misfortunes and their resulting failure to consider the wider range of situational factors that tend to moderate onlookers' impressions. Discussion focuses on additional mechanisms that may contribute to overly pessimistic expectations as well as the role of such expectations in producing unnecessary social anxiety.
