Modification of the startle reflex in a community sample: do one or two dimensions of psychopathy underlie emotional processing?

Recent research on psychopathy has begun to explore two dimensions that possibly underlie psychopathy–one related more to emotional and interpersonal traits, and another related more to antisocial behaviors. A community sample of adults was assessed for psychopathy using Hare's (1991) Psychopathy Checklist-Revised (PCL-R). Eyeblinks elicited by startle probes were recorded while participants viewed pictures of emotionally-laden stimuli. Consistent with previous research, participants scoring high on PCL-R Factor 2 (“antisocial”) showed no affective modification of startle if they also scored high on PCL-R Factor 1 (“emotional detachment”). When the factor scores were analyzed together as continuous variables in a regression analysis, however, affective modification of startle was negatively related to Factor 1 but positively related to Factor 2. The results thus provide further support for a two-factor model of psychopathy.     

Aiming for career success: The role of learning goal orientation in mentoring relationships

Learning goal orientation of mentors and protégés was investigated as it relates to protégés’ mentoring functions received and outcomes (i.e., managerial career aspirations and career satisfaction). Data from 217 mentor-protégé dyads comprised of working professionals from a variety of industries were analyzed using multivariate analysis of covariance. Results indicated that protégés who possessed high levels of learning goal orientation similar to their mentor were associated with the highest levels of psychosocial support. These protégés also reported higher levels of career development, idealized influence, enacted managerial aspirations, desired managerial aspirations, and career satisfaction when compared to mentor-protégé dyads who possessed low levels of learning goal orientation or dyads with dissimilar levels of learning goal orientation. Implications for practice and future research are discussed.     

Long-term consolidation and retention of learning-induced tuning plasticity in the auditory cortex of the guinea pig.

The major goal of this study was to determine whether classical conditioning produces long-term neural consolidation of frequency tuning plasticity in the auditory cortex. Local field potentials (LFPs) were obtained from chronically implanted adult male Hartley guinea pigs that were divided into conditioning (n = 4) and sensitization control (n = 3) groups. Tuning functions were determined in awake subjects for average LFPs (approximately 0.4 to 36.0 kHz, -20 to 80 dB) immediately before training as well as 1 h and 1, 3, 7, and 10 days after training; sensitization subjects did not have a 10-day retention test. Conditioning consisted of a single session of 30 to 45 trials of a 6-s tone (CS, 70 dB) that was not the best frequency (BF, peak of a tuning curve), followed by a brief leg shock (US) at CS offset. Sensitization control animals received the same density of CS and US presentations unpaired. Heart rate recordings showed that the conditioning group developed conditioned bradycardia, whereas the sensitization control group did not. Local field potentials in the conditioning group, but not in the sensitization group, developed tuning plasticity. The ratio of responses to the CS frequency versus the BF were increased 1 h after training, and this increase was retained for the 10-day period of the study. Both tuning plasticity and retention were observed across stimulus levels (10-80 dB). Most noteworthy, tuning plasticity exhibited consolidation (i.e., developed greater CS-specific effects across retention periods), attaining asymptote at 3 days. The findings indicate that LFPs in the auditory cortex have three cardinal features of behavioral memory: associative tuning plasticity, long-term retention, and long-term consolidation. Potential cellular and subcellular mechanisms of LFP tuning plasticity and long-term consolidation are discussed.     

Psychological management intervention guidelines for rape survivors with post-traumatic stress disorder (PTSD): A brief exploratory systematic literature review

This exploratory systematic literature review aimed to characterise the current evidence on psychological management intervention guidelines for use with rape survivors with post-traumatic stress disorder (PTSD) symptoms. For the data searches we accessed the following electronic databases: Google Scholar, Science Direct, EBSCOhost, and PsychInfo. We utilised search terms with variations of the following key words: psychological management guidelines of PTSD*, rape survivors*. Inclusion criteria were guidelines for rape survivors with PTSD that consider referral, treatment, and preventive and health promotion in an international setting. We excluded guidelines that did not address PTSD resulting from rape in an international setting. We employed a narrative synthesis data analysis approach to integrate the evidence from across studies. Findings suggest prevalent guidelines for rape survivors with PTSD focus on cognitive behavioural therapy and other psychological management interventions in highly specialised areas and Primary Health Care (PHC) settings in international countries, but not in other countries such as South Africa. Emerging guidelines are needed for PTSD psychological management interventions in rape care clinics situated in South Africa.     

The experiences of therapists using a new client‐centred psychometric instrument,PSYCHLOPS (Psychological Outcome Profiles)

PSYCHLOPS (‘Psychological Outcome Profiles’) is a newly developed client‐generated psychometric instrument which can be used as an outcome measure. Uniquely, it asks clients to state their own problems, in their own words. As part of its validation, we used it alongside an existing measure, CORE‐OM (‘Clinical Outcomes Routine Evaluation – Outcome Measure’). Based on a qualitative methodology, we report here on the first‐hand experiences of four therapists using both instruments. The key themes that emerged from therapists’ responses were feasibility, validity and usefulness. Both questionnaires were perceived as complementing each other, the qualitative information from PSYCHLOPS balancing the quantitative information from CORE‐OM and that both could contribute to the therapist‐client interaction. The key features of PSYCHLOPS are likely to prove attractive to therapists and should increase acceptance and uptake of outcome measures.     

Surviving childhood cancer: quality of life and parental regulatory focus

Applying Regulatory Focus Theory (RFT), the authors predicted that among survivors of childhood cancer, quality of life (QOL) may be compromised by prevention-focused parenting characterized by an overly protective concern with possible mishaps and illness recurrence rather than promotion-focused parenting encouraging expectations of recovery and a normal life. Interviews with parents of 64 survivors (M age = 13.83 years) of acute lymphoblastic leukemia (ALL) or central nervous system (CNS) tumors were coded for reports of promotion or prevention-oriented parenting and positive and negative expectancies. Overall, parents expressed more promotion than prevention focus, especially in relation to general rather than illness-related contexts. Greater use by parents of prevention focus in general contexts predicted lower QOL for survivors (as rated both by parents and survivors themselves) and less satisfactory parental well-being. These effects were independent of a main effect for type of cancer, with survivors of ALL having higher QOL.     

The tale is in the tail: an alternative hypothesis for psychophysical performance variability in dyslexia

Dyslexic groups have been reported to display poorer mean performance than groups of normal readers on a variety of psychophysical tasks. However, inspection of the distribution of individual scores for each group typically reveals that the majority of dyslexic observers actually perform within the normal range. Differences between group means often reflect the influence of a small number of dyslexic individuals who perform very poorly. While such findings are typically interpreted as evidence for specific perceptual deficiencies in dyslexia, caution in this approach is necessary. In this study we examined how general difficulties with task completion might manifest themselves in group psychophysical studies. Simulations of the effect of errant or inattentive trials on performance produced patterns of variability similar to those seen in dyslexic groups. Additionally, predicted relationships between the relative variability in dyslexic and control groups, and the magnitude of group differences bore close resemblance to the outcomes of a meta-analysis of empirical studies. These results suggest that general, nonsensory difficulties may underlie the poor performance of dyslexic groups on many psychophysical tasks. Implications and recommendations for future research are discussed.     

A new approach to assessing optimism: the development of a german version of the positive and negative expectancies questionnaire (paneq-g)

This study describes the construction and validation of a German version of the Positive and Negative Expectancies Scale, PANEQ-G, which is based on the original English version of the PANEQ. The German version showed the same factor structure as the original, comprising the three subscales of Negative Affectivity/Pessimism, Positive Affectivity/Optimism, and Fighting Spirit. The reliability data for the new scale were acceptable, and the factor structure was confirmed by means of a confirmatory factor analysis in an independent sample. As expected, concurrent validation uncovered substantial correlations of the three established scales. Negative Affectivity/Pessimism was related to Neuroticism and Positive Affectivity/Optimism was related to Extraversion. Fighting Spirit, the third scale, was related to Self-Efficacy and Conscientiousness. The PANEQ-G provides a reliable and valid instrument that can be used in conjunction with the original PANEQ for cross-cultural studies on Optimism and Pessimism. It also offers a new third component, Fighting Spirit, which can enrich research in this area.     

Customer service as a function of shopper's attire

A field experiment explored whether a female shopper's appearance would influence the customer service she received. Specifically, a female confederate dressed in formal work clothes (skirt and blouse) or informal gym clothes (tights and t-shirt) entered a series of randomly selected women's clothing stores in a large mall and proceeded to "shop." The amount of time that passed before an employee approached and acknowledged the confederate served as the dependent variable. As hypothesized, she was acknowledged significantly sooner when formally attired than when informally dressed. Thus, clothing, like other aspects of appearance, influences how people are evaluated and treated by others.     

Religious involvement and the forgiving personality

The relationship between religious involvement and forgiveness was assessed in three samples of Western Europeans living in a social environment dominated by the Catholic tradition. The samples comprised nonbelievers/nonattendees, believers/nonattendees, believers/regular attendees, and religious people. Age and religious involvement were shown to affect the willingness to forgive in an interactive way: The effect of religious involvement was stronger for the elderly group. We also found that what made the difference in the willingness to forgive was mainly the social commitment to religion (attendance in church and the taking of vows), not mere personal beliefs. In addition, age and religious involvement were found to affect blockage towards forgiveness in an additive way.
