What is "special" about face perception?

There is growing evidence that face recognition is "special" but less certainty concerning the way in which it is special. The authors review and compare previous proposals and their own more recent hypothesis, that faces are recognized "holistically" (i.e., using relatively less part decomposition than other types of objects). This hypothesis, which can account for a variety of data from experiments on face memory, was tested with 4 new experiments on face perception. A selective attention paradigm and a masking paradigm were used to compare the perception of faces with the perception of inverted faces, words, and houses. Evidence was found of relatively less part-based shape representation for faces. The literatures on machine vision and single unit recording in monkey temporal cortex are also reviewed for converging evidence on face representation. The neuropsychological literature is reviewed for-evidence on the question of whether face representation differs in degree or kind from the representation of other types of objects.     

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.

What can we learn from patients with heart failure about exercise adherence? A systematic review of qualitative papers.

Objectives: Keeping physically active has been shown to bring positive outcomes for patients diagnosed with heart failure (HF). However, a number of individuals with this health problem do not undertake regular exercise. A review of extant qualitative research was conducted to explore what it can tell us about barriers and enablers to physical activity among people with HF. Methods: A systematic search, involving electronic databases and endeavors to locate gray literature, was carried out to identify relevant qualitative studies published from 1980 onward. Data from retrieved papers were combined using framework analysis. Papers read in full numbered 32, and 20 were included in the review. Results: Synthesis of results from the 20 studies resulted in 4 main themes: Changing soma, negative emotional response, adjusting to altered status, and interpersonal influences. How individuals responded to their diagnosis and their altered physical status related to their activity levels, as did the degree of encouragement to exercise coming from family, friends, and professionals. These findings can be connected to the theory of behavioral change developed by Bandura, known as social cognitive theory (SCT). Conclusions: SCT may be a useful framework for developing interventions to support patients with HF in undertaking and maintaining regular exercise patterns. Specific components of SCT that practitioners may wish to consider include self-efficacy and outcome expectancies. These were issues referred to in papers for the systematic review that appear to be particularly related to exercise adherence. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

What is the shelf life of a test? The effect of time on the psychometrics of a cognitive ability test battery.

The psychometric stability of the Armed Services Vocational Aptitude Battery was studied with data collected at 5 points over a 16-year period using item response theory (IRT) methods. Although 25 of the 200 items changed significantly over the years across 3 different gender-ethnic groups (i.e., White men, White women, and Black men), the overall characteristics of the tests were not severely affected by item-level changes. Items from tests that were more semantically laden were found to be more susceptible to the effects of time compared with those that focused on skills and principles. The findings are discussed in the context of the effects of time on the effectiveness of psychological measures. A call is made to test developers and test users to pay attention to the shelf life of their tests. The use of IRT methods for studying the effects of time on psychometrics is also 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.

What are his methods? What facts should he know?" Excerpted statements from the letters of Allport, Boring, Carmichael, Dashiell, Elliott, Hilgard, Leeper, Merrill, Murphy, Robert Sears, Tolman, W. L. Wells, and Woodworth are presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Are you interested? A meta-analysis of relations between vocational interests and employee performance and turnover.

A common belief among researchers is that vocational interests have limited value for personnel selection. However, no comprehensive quantitative summaries of interests validity research have been conducted to substantiate claims for or against the use of interests. To help address this gap, we conducted a meta-analysis of relations between interests and employee performance and turnover using data from 74 studies and 141 independent samples. Overall validity estimates (corrected for measurement error in the criterion but not for range restriction) for single interest scales were .14 for job performance, .26 for training performance, –.19 for turnover intentions, and –.15 for actual turnover. Several factors appeared to moderate interest–criterion relations. For example, validity estimates were larger when interests were theoretically relevant to the work performed in the target job. The type of interest scale also moderated validity, such that corrected validities were larger for scales designed to assess interests relevant to a particular job or vocation (e.g., .23 for job performance) than for scales designed to assess a single, job-relevant realistic, investigative, artistic, social, enterprising, or conventional (i.e., RIASEC) interest (.10) or a basic interest (.11). Finally, validity estimates were largest when studies used multiple interests for prediction, either by using a single job or vocation focused scale (which tend to tap multiple interests) or by using a regression-weighted composite of several RIASEC or basic interest scales. Overall, the results suggest that vocational interests may hold more promise for predicting employee performance and turnover than researchers may have thought.

Are psychotic psychopathology and neurocognition orthogonal? A systematic review of their associations.

A systematic review (58 studies, 5,009 individuals) is presented of associations between psychopathological dimensions of psychosis and measures of neurocognitive impairment in subjects with a lifetime history of nonaffective psychosis. Results showed that negative and disorganized dimensions were significantly but modestly associated with cognitive deficits (correlations from -.29 to -.12). In contrast, positive and depressive dimensions of psychopathology were not associated with neurocognitive measures. The patterns of association for the 4 psychosis dimensions were stable across neurocognitive domains and were independent of age, gender, and chronicity of illness. In addition, significantly higher correlations were found for the negative dimension in relation to verbal fluency (p = .005) and for the disorganized dimension in relation to reasoning and problem solving (p = .004) and to attention/vigilance (p = .03). Psychotic psychopathology and neurocognition are not entirely orthogonal, as heterogeneity in nonaffective psychosis is weakly but meaningfully associated with measures of neurocognition. This association suggests that differential latent cerebral mechanisms underlie the cluster of disorganized and negative symptoms versus that of positive and affective symptoms.

A meta-analysis of work–family conflict and various outcomes with a special emphasis on cross-domain versus matching-domain relations.

A literature review of studies analyzing work–family conflict and its consequences was conducted, and 427 effect sizes were analyzed meta-analytically. Work–family conflict was analyzed bidirectionally in terms of work interference with family (WIF) and family interference with work (FIW). We assessed 3 categories of potential outcomes: work-related outcomes, family-related outcomes, and domain-unspecific outcomes. Results show that WIF and FIW are consistently related to all 3 types of outcomes. Both types of interrole conflict showed stronger relationships to same-domain outcomes than to cross-domain outcomes. Thus, WIF was more strongly associated with work-related than with family-related outcomes, and FIW was more strongly associated with family-related than with work-related outcomes. In moderator analyses, parenthood could not explain variability in effect sizes. However, time spent at work did moderate the relationships between WIF and family-related outcomes, as well as FIW and domain-unspecific outcomes.

Research in alternative medicine. What is documented, and what is documentation?

A study of the literature describing research on alternative medicine showed that, in general, the research was of poor quality. Any clinical effect of kinesiology had not been documented. Only few studies on reflexology had been controlled. Several controlled studies on healing showed significant effect, mainly in patients with psychosomatic disorders, or when the patient had great faith in the healer. Acupuncture seems to be effective against nausea, in patients with chronic pain and in patients who have had stroke. The data do not support the claim that acupuncture is effective for asthma or addiction. In the case of homeopathy the evidence from clinical trials is positive but not sufficient to draw a definite conclusion, for example, is it better than placebo? The majority of studies seems to disregard the principle of homeopathy, i.e. that the treatment should be individualised. Even if the documented effect of alternative medicine is not convincing, the effect is favourable empirically and may in itself be sufficient to give practitioners of alternative medicine an authorization. The term "alternative medicine" should be replaced by "complementary medicine".     

A person-oriented perspective on sexual offenders, offending trajectories, and risk of recidivism: A new challenge for policymakers, risk assessors, and actuarial prediction?

Current risk assessment tools are embedded in a variable-oriented perspective and based on the assumption that the risk of reoffending is linear, additive, and relatively stable over time. As a result, actuarial instruments tend to overestimate the risk of violent/sexual recidivism for some sex offenders while underestimating this risk for others. One of the main causes of such predictive inaccuracies is the inability of current actuarial tools to account for the dynamic aspects of offending trajectories over time. Using a person-oriented approach, the current study examined the presence of offending trajectories in sex offenders using measures of offending at multiple time points in adulthood to examine the risk of violent/sexual reoffending. The study was based on a sample of 246 adult males convicted of a sexual offense between 1994 and 1998. Group-based modeling was used to identify offending trajectories, while Cox proportional hazard was used to examine the links between the identified trajectories and recidivism. Findings suggest that a sex crime is more reflective of a transitory phase of the criminal career rather than evidence of a “sexual criminal career” in the making. The findings challenge underlying assumptions of current actuarial tools and calls for a more sophisticated approach to risk assessment that accounts for offending patterns.

Are leader stereotypes masculine? A meta-analysis of three research paradigms.

This meta-analysis examined the extent to which stereotypes of leaders are culturally masculine. The primary studies fit into 1 of 3 paradigms: (a) In Schein's (1973) think manager–think male paradigm, 40 studies with 51 effect sizes compared the similarity of male and leader stereotypes and the similarity of female and leader stereotypes; (b) in Powell and Butterfield's (1979) agency–communion paradigm, 22 studies with 47 effect sizes compared stereotypes of leaders' agency and communion; and (c) in Shinar's (1975) masculinity–femininity paradigm, 7 studies with 101 effect sizes represented stereotypes of leadership-related occupations on a single masculinity–femininity dimension. Analyses implemented appropriate random and mixed effects models. All 3 paradigms demonstrated overall masculinity of leader stereotypes: (a) In the think manager–think male paradigm, intraclass correlation = .25 for the women–leaders similarity and intraclass correlation = .62 for the men–leaders similarity; (b) in the agency–communion paradigm, g = 1.55, indicating greater agency than communion; and (c) in the masculinity–femininity paradigm, g = 0.92, indicating greater masculinity than the androgynous scale midpoint. Subgroup and meta-regression analyses indicated that this masculine construal of leadership has decreased over time and was greater for male than female research participants. In addition, stereotypes portrayed leaders as less masculine in educational organizations than in other domains and in moderate- than in high-status leader roles. This article considers the relation of these findings to Eagly and Karau's (2002) role congruity theory, which proposed contextual influences on the incongruity between stereotypes of women and leaders. The implications for prejudice against women leaders are also considered. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Antipsychotic drugs: is more worse? A meta-analysis of the published randomized control trials

OBJECTIVES: The purpose of this study was to evaluate the usefulness of transesophageal echocardiography before electrical cardioversion in patients with atrial fibrillation and to determine the mechanism of thromboembolism after cardioversion. BACKGROUND: Thromboembolic complications after electrical cardioversion of atrial fibrillation have been attributed to the dislodgment of preexistent left atrial thrombus during the resumption of atrial contraction. Transesophageal echocardiography has been proposed as a method of screening patients for left atrial thrombus before cardioversion. METHODS: Seventy transesophageal echocardiographic studies were performed in 66 patients, predominantly with nonvalvular atrial fibrillation, before direct current cardioversion. In addition, transesophageal echocardiography was performed during the cardioversion procedure in 15 patients and immediately after in 1 patient. RESULTS: Left atrial thrombus was detected in one patient (1.4%), and cardioversion was cancelled. Thromboembolic complications occurred in 4 patients, none of whom had evidence of left atrial thrombus before cardioversion. Within 10 s of successful cardioversion, left atrial spontaneous echo contrast appeared in five patients, increased in one patient and was unchanged in nine patients. Patients with new or increased spontaneous echo contrast had more impaired atrial contraction and slower initial heart rates after cardioversion than those without. Left ventricular contraction was also impaired transiently by cardioversion. CONCLUSIONS: Transesophageal echocardiographic detection of left atrial thrombus before direct current cardioversion is important but infrequent in patients with predominantly nonvalvular atrial fibrillation. The occurrence of thromboembolic complications in the absence of demonstrable left atrial thrombus and the new development of spontaneous echo contrast in association with the transient atrial dysfunction ("stunning") caused by cardioversion suggest that cardioversion may promote new thrombus formation, in which case all patients should receive full anticoagulant therapy at the time of cardioversion.     

Why do lie-catchers fail? A lens model meta-analysis of human lie judgments.

Decades of research has shown that people are poor at detecting lies. Two explanations for this finding have been proposed. First, it has been suggested that lie detection is inaccurate because people rely on invalid cues when judging deception. Second, it has been suggested that lack of valid cues to deception limits accuracy. A series of 4 meta-analyses tested these hypotheses with the framework of Brunswik's (1952) lens model. Meta-Analysis 1 investigated perceived cues to deception by correlating 66 behavioral cues in 153 samples with deception judgments. People strongly associate deception with impressions of incompetence (r = .59) and ambivalence (r = .49). Contrary to self-reports, eye contact is only weakly correlated with deception judgments (r = ?.15). Cues to perceived deception were then compared with cues to actual deception. The results show a substantial covariation between the 2 sets of cues (r = .59 in Meta-Analysis 2, r = .72 in Meta-Analysis 3). Finally, in Meta-Analysis 4, a lens model analysis revealed a very strong matching between behaviorally based predictions of deception and behaviorally based predictions of perceived deception. In conclusion, contrary to previous assumptions, people rarely rely on the wrong cues. Instead, limitations in lie detection accuracy are mainly attributable to weaknesses in behavioral cues to deception. The results suggest that intuitive notions about deception are more accurate than explicit knowledge and that lie detection is more readily improved by increasing behavioral differences between liars and truth tellers than by informing lie-catchers of valid cues to deception.

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.

Does pretreatment severity moderate the efficacy of psychological treatment of adult outpatient depression? A meta-analysis.

Objective: It is widely believed that psychological treatment has little effect on more severely depressed patients. This study assessed whether pretreatment severity moderates psychological treatment outcome relative to controls by means of meta-analyses. Method: We included 132 studies (10,134 participants) from a database of studies (www.evidencebasedpsychotherapies.org) in which the effects of psychological treatment on adult outpatients with a depressive disorder or an elevated level of depressive symptoms were compared with a control condition in a randomized controlled trial. Two raters independently extracted outcome data and rated study characteristics. We conducted metaregression analyses assessing whether mean pretreatment depression scores predicted psychological treatment versus control condition posttreatment effect size and subgroup analyses summarizing the results of studies reporting within-study analyses of depression severity and psychological treatment outcome. Results: Psychological treatment was found to be consistently superior to control conditions (d = 0.40–0.88). We found no indication that pretreatment mean depression scores predicted psychological treatment versus control condition posttreatment effect size, even after adjusting for relevant study characteristics. However, among the smaller subset of studies that reported within-study severity analyses, posttreatment effect sizes were higher for high-severity patients (d = 0.63) than for low-severity patients (d = 0.22) when psychological treatment was efficacious relative to a more stringent control. Conclusion: Contrary to conventional wisdom, our findings suggest that when compared with control conditions, psychological treatment might be more efficacious for high-severity than for low-severity patients. Because the number of studies reporting within-study severity analyses is small, we recommend that future studies routinely report tests for Severity × Treatment interactions.

Does distraction reduce the alcohol–aggression relation? A cognitive and behavioral test of the attention-allocation model.

Objective: This study provided the first direct test of the cognitive underpinnings of the attention-allocation model and attempted to replicate and extend past behavioral findings for this model as an explanation for alcohol-related aggression. Method: A diverse community sample (55% African American) of men (N = 159) between 21 and 35 years of age (M = 25.80) were randomly assigned to 1 of 2 beverage conditions (i.e., alcohol, no-alcohol control) and 1 of 2 distraction conditions (i.e., distraction, no-distraction). Following beverage consumption, participants were provoked via reception of electric shocks and a verbal insult from a fictitious male opponent. Participants' attention allocation to aggression words (i.e., aggression bias) and physical aggression were measured using a dot probe task and a shock-based aggression task, respectively. Results: Intoxicated men whose attention was distracted displayed significantly lower levels of aggression bias and enacted significantly less physical aggression than intoxicated men whose attention was not distracted. However, aggression bias did not account for the lower levels of alcohol-related aggression in the distraction, relative to the no-distraction, condition. Conclusions: These results replicated and extended past evidence that cognitive distraction is associated with lower levels of alcohol-related aggression in highly provoked males and provide the first known cognitive data to support the attentional processes posited by the attention-allocation model. Discussion focused on how these data inform intervention programming for alcohol-related aggression. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Does group climate mediate the group leadership–group member outcome relationship?: A test of Yalom's hypotheses about leadership priorities.

I. D. Yalom's (1995) hypothesis that group climate mediates the relationship between leadership and outcome was tested. Group leaders (N?=?43) recorded intentions, and adolescent group members (N?=?233) rated climate after 8 semistructured group sessions. Members also rated satisfaction at termination. Leader intentions comprised 4 dimensions: therapeutic work, safe environment, interpersonal, and group structure. Changing group climates did mediate between these intentions and member outcome. Therapeutic work was negatively related and safe environment was positively related to an increasingly active and engaged climate, which was related to treatment benefit. Group structure and possibly interpersonal intentions were related to a climate decreasing in conflict and distance, which was related to a positive leader relationship. The importance of leaders focusing on group process rather than individual change is highlighted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does vocational overshadowing even exist? A test of the robustness of the vocational overshadowing bias.

Vocational overshadowing (P. M. Spengler, D. L. Blustein, & D. C. Strohmer, 1990 ) is a hypothesized underemphasis of clients' career concerns when more interesting, prestigious, or economically rewarding "personal" problems coexist. This study tested the robustness of the vocational overshadowing bias by using an expanded array of case material, by including practicing counseling psychologists (n?=?125) and clinical psychologists (n?=?121), and by assessing the moderating effects of clinician information processing and attitudinal characteristics. Clinical psychologists were more likely than counseling psychologists to underemphasize vocational concerns combined with severe noncareer problems. More complex thinking about career counseling and higher preference for working with career problems were associated with greater attention to clients' career concerns. However, no clear evidence was found for the vocational overshadowing bias by either equal or less severe noncareer problems. Implications of these findings for career counseling and clinical judgment research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Different inhibition of conditioned avoidance response by clozapine and DA D? and D? antagonists in male mice.

The effects of clozapine (2.5 and 5 mg/kg), SCH 23390 (0.05 and 0.1 mg/kg), and raclopride (0.1 and 0.5 mg/kg) on the acquisition and performance of a conditioned avoidance response (CAR) were studied in BALB/C mice. The high dose of clozapine decreased avoidances and crossings in acquisition and performance. SCH 23390 had no effect on acquisition, whereas a decrease of avoidances and crossings was produced by the high dose in performance. The high dose of raclopride decreased avoidances and crossings in acquisition but had no effects on performance. The results suggest that the mechanisms by which these drugs affect avoidance are not the same. This difference may reflect an action on different subtypes of DA receptors that produces different effects on motor behavior. It seems that in all cases where CAR is impaired, locomotor activity is also suppressed; therefore, a parsimonious interpretation is that the CAR procedure is sensitive to motor effects.
