The ADP-IV questionnaire: differential validity and concordance with the semi-structured interview

The Assessment of DSM-IV Personality Disorders questionnaire (ADP-IV) is a self-report measure of the DSM-IV Axis II personality disorders (PDs). The ADP-IV assesses for each DSM-IV criterion its typicality as well as the accompanying distress and impairment. This study investigates two important aspects of the construct validity of the ADP-IV: (a) the differential validity (i.e., the ability to differentiate between a sample of the general Flemish population ( n = 659) and a sample of psychiatric inpatients ( n = 487) with a high prevalence of clinical PD diagnoses, and patients with and without a PD in the psychiatric sample; (b) the convergent validity with the SCID-II semi-structured interview in a population of psychiatric inpatients ( n = 59). The results indicate a good differential validity: the dimensional scales and the categorical measures discriminated well between both groups and between patients with and without a PD diagnosis in the psychiatric sample. Concerning the concordance with the SCID-II, a decent level of agreement is exemplified by a correlation of.67 between the dimensional total scores of both instruments and by kappa coefficients for an "any" Axis II diagnosis at the.50 level. In conclusion, the results indicate that the ADP-IV is an efficient method for assessing PD in dimensional and categorical ways.     

Comparative and categorical spatial judgments in the monkey: “high” and “low”

Adult human subjects can classify the height of an object as belonging to either of the high or low categories by utilizing an abstract concept of midline that divides the vertical dimension into two halves. Children lack this abstract concept of midline, do not have a sense that these categories are directional opposites, and their categorical and comparative usages of high(er) or low(er) are restricted to the corresponding poles. We investigated the abilities of a rhesus monkey to perform categorical judgments in space. We were also interested in the presence of the congruity effect (a decrease in response time when the objects compared are closer to the category pole) in the monkey. The presence of this phenomenon in the monkey would allow us to relate the behavior of the animal to the two major competing hypotheses that have been suggested to explain the congruity effect in humans: the analog and semantic models. The monkey was trained in delayed match-to-sample tasks in which it had to categorize objects as belonging to either a high or low category. The monkey was able to generate an abstract notion of midline in a fashion similar to that of adult human subjects. The congruity effect was also present in the monkey. These findings, taken together with the notion that monkeys are not considered to think in propositional terms, may favor an analog comparison model in the monkey.     

Spared anterograde memory for shock-probe fear conditioning after inactivation of the amygdala

Previous studies have shown that amygdala lesions impair avoidance of an electrified probe. This finding has been interpreted as indicating that amygdala lesions reduce fear. It is unclear, however, whether amygdala-lesioned rats learn that the probe is associated with shock. If the lesions prevent the formation of this association, then pretraining reversible inactivation of the amygdala should impair both acquisition and retention performance. To test this hypothesis, the amygdala was inactivated (tetrodotoxin; TTX; 1 ng/side) before a shock-probe acquisition session, and retention was tested 4 d later. The data indicated that, compared with rats infused with vehicle, rats infused with TTX received more shocks during the acquisition session, but more importantly, were not impaired on the retention test. In Experiment 2, we assessed whether the spared memory on the retention test was caused by overtraining during acquisition. We used the same procedure as in Experiment 1, with the exception that the number of shocks the rats received during the acquisition session was limited to four. Again the data indicated that amygdala inactivation did not impair performance on the retention test. These results indicate that amygdala inactivation does not prevent the formation of an association between the shock and the probe and that shock-probe deficits during acquisition likely reflect the amygdala's involvement in other processes.     

Paradoxical facilitation of attention in healthy humans

Transcranial magnetic stimulation (TMS)-induced virtual lesions in healthy subjects can be used to test neurofunctional models of disease. The interhemispheric rivalry model of heminglect is well suited for such investigations, as simple predictions derived from clinical data can be tested without the caveats normally associated with lesion studies. One of these predictions is that release from contralateral inhibition should lead to increased parietal responsiveness, which, in turn, would enhance spatial attention. Here, we detail studies showing TMS-induced paradoxical functional facilitation of attention in healthy individuals and highlight their contribution to the understanding and treatment of neglect syndromes.     

Psychological distress with relationship satisfaction is moderated by anticipatory relational savoring among non-deployed military partners

This study recruited participants whose partners were deployed for active-duty military service to examine whether anticipatory relational savoring moderated the association of psychological distress with relationship satisfaction. Two weeks prior to their partner's deployment (T1), participants (N = 73) completed a self-report measure of relationship satisfaction. Then, 2 weeks into their partner's deployment (T2), participants completed self-report measures of stress, loneliness, and depression (combined into a composite index of psychological distress), and relationship satisfaction. Participants also completed a stream-of-consciousness task at T2 in which they imagined and discussed their partner's return from deployment. We coded the stream-of-consciousness task for anticipatory relational savoring regarding their upcoming reunion with their deployed partner. We found that anticipatory relational savoring moderated the association of psychological distress with during-deployment relationship satisfaction after adjusting for demographics, interpersonal variables, and deployment-specific variables; the association did not hold after adjusting for pre-deployment relationship satisfaction, and thus was robust when considering the distress-satisfaction association during the deployment but was not when considering changes in relationship satisfaction from pre- to during-deployment. We discuss the potential importance of anticipatory relational savoring for this unique population.     

Factor analysis of the Spanish Burnout Inventory among public administration employees

Burnout has been recognized as an important stress‐related problem. Researchers have been troubled by some of the psychometric limitations of the questionnaires developed to evaluate burnout. This study was designed to assess the factor structure of the Spanish Burnout Inventory in a sample of 548 Brazilian public administration employees. This instrument comprises 20 items distributed in four dimensions: enthusiasm toward the job (5 items), psychological exhaustion (4 items), indolence (6 items), and guilt (5 items). The factor structure was examined through confirmatory factor analysis. To assess the factorial validity of the Spanish Burnout Inventory, four alternative models were tested. The four‐factor model obtained an adequate data fit for the sample, χ²(164) = 514.358, p < .001, RMSEA = .062, GFI = .910, NFI = .915, CFI = .940, and AIC = 606.358. The results showed that the four‐model factor of the Spanish Burnout Inventory possesses adequate psychometric properties in the Brazilian cultural context. Implications for future research and practice are also discussed.     

Dispositional optimism,optimism priming,and prevention of ego depletion

Exerting self‐control leads to a diminished capacity to carry out successive acts of self‐control, a process termed ego depletion. The present study investigated whether dispositional optimism, priming of an optimistic orientation, or their interaction can counteract the ego depletion effect. A total of 160 participants performed a self‐control‐demanding weight‐lifting task on two occasions. Half of the participants were depleted between the two weight‐lifting tasks. Because depletion of self‐regulatory resources can undermine optimism half of the participants in the depletion, and no‐depletion condition were primed for an optimistic orientation before performing the second self‐control task. Results demonstrated an interaction between dispositional optimism and optimism priming. Only in participants high in dispositional optimism did the optimism prime lead to undiminished persistence on the weight‐lifting task. These results demonstrate that dispositional optimism may lead to improved goal persistence in the face of adversity only under conditions in which optimistic schemas are activated.

Scientists’ Argumentative Reasoning

Reasoning, defined as the production and evaluation of reasons, is a central process in science. The dominant view of reasoning, both in the psychology of reasoning and in the psychology of science, is of a mechanism with an asocial function: bettering the beliefs of the lone reasoner. Many observations, however, are difficult to reconcile with this view of reasoning; in particular, reasoning systematically searches for reasons that support the reasoner’s initial beliefs, and it only evaluates these reasons cursorily. By contrast, reasoners are well able to evaluate others’ reasons: accepting strong arguments and rejecting weak ones. The argumentative theory of reasoning accounts for these traits of reasoning by postulating that the evolved function of reasoning is to argue: to find arguments to convince others and to change one’s mind when confronted with good arguments. Scientific reasoning, however, is often described as being at odds with such an argumentative mechanisms: scientists are supposed to reason objectively on their own, and to be pigheaded when their theories are challenged, even by good arguments. In this article, we review evidence showing that scientists, when reasoning, are subject to the same biases as are lay people while being able to change their mind when confronted with good arguments. We conclude that the argumentative theory of reasoning explains well key features of scientists’ reasoning and that differences in the way scientists and laypeople reason result from the institutional framework of science.     

High Trait Cheerfulness Individuals are More Sensitive to the Emotional Environment

The aim of this paper was to study whether trait cheerfulness modulates changes in state cheerfulness as a result of exposing participants to affective stimuli. Two studies with a within-participant experimental design were carried out. Forty-eight (33 women) and sixty-four (45 women) undergraduate psychology students were selected as Sample 1 and Sample 2, respectively, for scoring high or low on the Trait Form of the State-Trait-Cheerfulness Inventory (STCI-T; Ruch et al. in Humor Int J Humor Res 9:303–339, 1996; Ruch et al. in Personal Individ Differ 22:477–491, 1997). Participants watched amusing, neutral, and sad film clips and reported their affective states before and after viewing them. In the second study, heart rate and skin conductance level were also recorded. Results showed that people with high trait cheerfulness reported greater changes in state cheerfulness when exposed to both amusing and sad film clips, showing larger increases and decreases in state cheerfulness, respectively, than participants with low trait cheerfulness. Effects were not mediated by social desirability. Furthermore, people with low trait cheerfulness showed a greater heart rate deceleration during the visioning of the clips compared to high trait cheerfulness participants, especially in an amusing scene with high emotional load. No modulation on trait cheerfulness was found for skin conductance level. Data with self-report and electrophysiological measures are discussed, highlighting that high trait cheerfulness people are more permeable to affective events, perhaps showing a better understanding and management of them.
