Similarities Between the Psychological Profiles of Complex Regional Pain Syndrome and Conversion Disorder Patients

The psychological profile of 17 Complex Regional Pain Syndrome type I (CRPS) and 20 Conversion Disorder (CD) patients were compared, using the Minnesota Multiphasic Personality Inventory (MMPI) and standardized, semistructured psychological interviews. Both groups presented abnormally high somatization scores. Low anxiety scores in both groups indicate that somatization may have served as a defense mechanism to bind anxiety. Depression was apparent in both groups, indicating that psychological distress accompany these syndromes. About one third of the participants in both groups presented comorbid Axis I disorders, mostly depression and PTSD. CRPS patients have traditionally been looked upon as suffering from mainly organic symptoms, whereas CD patients have been labeled as psychiatric patients. These results may indicate the need to reexamine the traditional classifications in respect to disorders that involve body and mind.     

The Effect of Comparative Advertising on Consumer Perceptions: Similarity or Differentiation?

Purpose  

Comparative advertising is seen as an effective means of conveying the differentiating advantages of a brand. Nevertheless, several studies show that a primary effect of comparative advertising is to lead consumers to associate the advertised brand with the competitor brand identified within the ad: it seems that comparison generates perceived similarity among brands instead of differentiation, per se. In order to clarify the issue, the aim of the research is to investigate the relative effectiveness of comparative and non-comparative advertising in communicating the differentiating attributes of a brand.     

Gaze following in the red-footed tortoise (Geochelone carbonaria)

Gaze following refers to the ability of an animal to orient its gaze direction to that of another organism. Such a behavior may be adaptive as it alerts the observer to important objects in the environment such as food or predators. This behavior has been shown in mammals and birds, but the evolutionary history and the distribution of this behavior throughout the animal kingdom remain unclear. Here, we show that a reptile, the red-footed tortoise (Geochelone carbonaria), is able to follow the gaze of a conspecific in a lookup task. Controls revealed that neither the mere presence of a conspecific nor the presentation of a light stimulus (without a demonstrator present) controlled the tortoises’ behavior. The findings indicate that the ability to follow gaze may be found in mammals, birds and reptiles and could have evolved before the amniotic line diverged, or may result from a general ability to learn.     

Cognitive outcomes of pediatric stroke

A limited number of longitudinal studies have investigated long-term neuropsychological development in the pediatric stroke population. This study retrospectively examines cognitive outcomes in 41 children with a history of stroke, with reference to age at stroke, laterality, region and mechanism of stroke. In the course of recovery, neuropsychological measures of intellectual functioning and memory were administered at two time points, whilst executive functioning, attention and academic skills were administered at one time point. As predicted, children with stroke performed significantly worse compared to normative expectations on all neuropsychological measures. Up to two thirds of children scored in the borderline impaired and impaired ranges on at least one domain of cognition. Performance on intellectual and memory assessment remained relatively stable over time. Younger age at stroke was found to be associated with poorer intellectual functioning. No effects of laterality of stroke on neuropsychological performance over time were found. Children with subcortical stroke demonstrated a greater improvement in immediate memory over time than children with cortical stroke. These findings reveal that children with stroke display long-term cognitive difficulties that typically remain stable over time. Attention and academic skills are particularly vulnerable to impairment. Further evidence that age at stroke is a significant factor in terms of cognitive outcome is provided, in support of the “early vulnerability” position.     

Imperfection,Indecision, and Hoarding

Hoarding disorder is a new DSM-5 disorder that causes functional impairment and affects 2 to 6% of the population (Frost and Steketee 2014). The current study evaluated a multiple mediation model with 243 undergraduate women in which indecisiveness (VOCI; Thordarson et al. Behaviour Research and Therapy, 42(11), 1289-1314, 2004) and decisional procrastination (DPS; Mann 1982) mediated the relationship between dimensions of perfectionism (F-MPS-B; Burgess et al. 2016a) and hoarding behavior (SI-R; Frost et al. Behaviour Research And Therapy, 42(10), 1163–1182, 2004) and excessive acquiring (CAS; Frost et al. Annual Review of Clinical Psychology, 8, 219–242, 2012). Multiple mediational analyses indicated a significant indirect effect for decisional procrastination, but not indecisiveness, in mediating evaluative concerns (but not striving) to SI-R Total, SI-R Clutter, SIR Excessive Acquisition, and both CAS subscales. Both mediators were significant pathways between evaluative concerns and SI-R Difficulty Discarding. These findings support a cognitive behavioral model of hoarding, suggesting that evaluative concerns produces problems in decision-making that influence acquisition, discarding, and clutter.

Feeling Good Makes Us Stronger: How Team Resilience Mediates the Effect of Positive Emotions on Team Performance

This study investigated the relationship between collective positive emotions at work and team resilience, expanding on the Broaden and Build theory of Fredrickson (Rev Gen Psychol 2:300–319, 1998; Am Psychol 56:218–226, 2001) at the collective (i.e., work teams) level of analysis. Through the aggregate scores of 1,076 employees (61 % men), grouped into 216 teams and belonging to 40 companies, five collective positive emotions were evaluated (i.e., enthusiasm, optimism, satisfaction, comfort, and relaxation) as well as team resilience. Additionally, ratings of the 216 supervisors of the teams were used to assess team performance (i.e., in- and extra-role performance). Structural equation modeling at the team level of analysis indicated that team resilience mediates the relationship between collective positive emotions and team performance, both in- and extra-role. The results highlight the importance of developing collective positive emotions to help teams to foster team resilience and improve their performance. The article concludes with practical strategies aimed at developing collective positive emotions, together with limitations and suggestions for future research.     

Convergence of multiple sources of information on infant individuality: neonatal behavior,infant behavior,and temperament reports

To shed light on the notion of enduring individual infant characteristics, convergence of three presumably interrelated measures of infant individuality was examined. Data collected included standardized behavioral assessments of the newborn (NBAS), maternal reports of infant temperament (at 3 and 9 months), and naturalistic observations of infant behavior at 1, 3, and 9 months. Infant temperament reports were significantly stable from 3 to 9 months; observed infant fussiness was significantly stable from 1 to 3 and 3 to 9 months; observed altertness/social responsiveness was not stable over time. Analyses of convergence of neonatal and infant behavior revealed that 9-month infant alertness/social responsiveness was significantly correlated with neonatal habituation. Similar analyses of neonatal behavior and reported temperament revealed that 3-month reported dullness was significantly correlated with neonatal habituation and range of state. At 9 months, temperament ratings of infant fussiness and unpredictability were significantly correlated with autonomic stability; fussiness was also significantly correlated with regulation of state. Finally, no significant relationships were observed between reported temperament and observed infant behavior. These results fail to support a simple notion of enduring individuality in infants over their first year of life.
