Rhesus monkeys (Macaca mulatta) adaptively monitor uncertainty while multi-tasking

As researchers explore animals’ capacity for metacognition and uncertainty monitoring, some paradigms allow the criticism that animal participants—who are always extensively trained in one stimulus domain within which they learn to avoid difficult trials—use task-specific strategies to avoid aversive stimuli instead of responding to a generalized state of uncertainty like that humans might use. We addressed this criticism with an uncertainty-monitoring task environment in which four different task domains were interleaved randomly trial by trial. Four of five macaques (Macaca mulatta) were able to make adaptive uncertainty responses while multi-tasking, suggesting the generality of the psychological signal that occasions these responses. The findings suggest that monkeys may have an uncertainty-monitoring capacity that is like that of humans in transcending task-specific cues and extending simultaneously to multiple domains.     

Anterior insula activity predicts the influence of positively framed messages on decision making

The neural mechanisms underlying the influence of persuasive messages on decision making are largely unknown. We address this issue using event-related fMRI to investigate how informative messages alter risk appraisal during choice. Participants performed the Iowa Gambling Task while viewing a positively framed, negatively framed, or control message about the options. The right anterior insula correlated with improvement in choice behavior due to the positively framed but not the negatively framed message. With the positively framed message, there was increased activation proportional to message effectiveness when less-preferred options were chosen, consistent with a role in the prediction of adverse outcomes. In addition, the dorsomedial and the left dorsolateral prefrontal cortex correlated with overall decision quality, regardless of message type. The dorsomedial region mediated the relationship between the right anterior insula and decision quality with the positively framed messages. These findings suggest a network of frontal brain regions that integrate informative messages into the evaluation of options during decision making.

Emotional faces capture spatial attention in 5-year-old children

Emotional facial expressions are important social cues that convey salient affective information. Infants, younger children, and adults all appear to orient spatial attention to emotional faces with a particularly strong bias to fearful faces. Yet in young children it is unclear whether or not both happy and fearful faces extract attention. Given that the processing of emotional faces is believed by some to serve an evolutionarily adaptive purpose, attentional biases to both fearful and happy expressions would be expected in younger children. However, the extent to which this ability is present in young children and whether or not this ability is genetically mediated is untested. Therefore, the aims of the current study were to assess the spatial-attentional properties of emotional faces in young children, with a preliminary test of whether this effect was influenced by genetics. Five-year-old twin pairs performed a dot-probe task. The results suggest that children preferentially direct spatial attention to emotional faces, particularly right visual field faces. The results provide support for the notion that the direction of spatial attention to emotional faces serves an evolutionarily adaptive function and may be mediated by genetic mechanisms.     

Auditory color constancy: Calibration to reliable spectral properties across nonspeech context and targets

Brief experience with reliable spectral characteristics of a listening context can markedly alter perception of subsequent speech sounds, and parallels have been drawn between auditory compensation for listening context and visual color constancy. In order to better evaluate such an analogy, the generality of acoustic context effects for sounds with spectral-temporal compositions distinct from speech was investigated. Listeners identified nonspeech sounds—extensively edited samples produced by a French horn and a tenor saxophone—following either resynthesized speech or a short passage of music. Preceding contexts were “colored” by spectral envelope difference filters, which were created to emphasize differences between French horn and saxophone spectra. Listeners were more likely to report hearing a saxophone when the stimulus followed a context filtered to emphasize spectral characteristics of the French horn, and vice versa. Despite clear changes in apparent acoustic source, the auditory system calibrated to relatively predictable spectral characteristics of filtered context, differentially affecting perception of subsequent target nonspeech sounds. This calibration to listening context and relative indifference to acoustic sources operates much like visual color constancy, for which reliable properties of the spectrum of illumination are factored out of perception of color.     

A taxometric study of hypochondriasis symptoms

Hypochondriasis has been conceptualized as both a distinct category that is characterized by a disabling illness preoccupation and as a continuum of health concerns. Empirical support for one of these theoretical models will clarify inconsistent assessment approaches and study designs that have impeded theory and research. To facilitate progress, taxometric analyses were conducted to determine whether hypochondriasis is best understood as a discrete category, consistent with the DSM, or as a dimensional entity, consistent with prevailing opinion and most self-report measures. Data from a large undergraduate sample that completed 3 hypochondriasis symptom measures were factor analyzed. The 4 factor analytically derived symptom indicators were then used in these taxometric analyses. Consistent with our hypotheses and existing theory, results supported a dimensional structure for hypochondriasis. Implications for the conceptualization of hypochondriasis and directions for future study are discussed.     

The effects of psychological security and insecurity on political attitudes and leadership preferences

Recent research from different perspectives suggests that uncertainty, mortality salience (MS), and other fundamental threats that cause feelings of insecurity motivate people to adhere to specific kinds of anxiety‐reducing political attitudes and values. In the current studies, we examined a complementary prediction that providing people with an alternative source of security would reduce their need to defend against insecurity, resulting in lower endorsement of the anxiety‐reducing political attitudes. Results supported this prediction, showing that security primes buffered or reversed the effects of insecurity and threats on political attitudes and leadership preferences. Participants primed with attachment security showed reduced liking of a strong, charismatic political candidate (Study 1), and lower support for the Iraq war, even in the face of mortality reminders (Study 2). We discuss these findings in the context of research on motivated social cognition, political psychology, and the effects of security and insecurity on attitudes and behaviors.

Integrative Complexity of Public Beliefs Toward Wildfire Management: Development of a Scale

Integrative complexity is a useful tool for examining the complex way people think about dichotomous, highly charged issues. However, the qualitative nature of this research is lengthy and requires much work from respondents and investigators alike. This paper presents the process by which a combination open‐ended and fixed‐item scale was developed to measure the complexity of thought that is consistent with integrative complexity. We used the controversial issue of wildfire management in developing the scale because it has become a pervasive natural resource concern that has divided the public's perceptions regarding its management. The resulting scale is designed for use in large surveys across any number of natural resource issues.     

Narcissism and unprovoked aggression

It is widely accepted that narcissists become aggressive when they experience ego‐threat. However, there is surprisingly little empirical research on the relationship between narcissism and aggression. Equivocal findings suggest that aggression in narcissists either occurs only in response to provocation, or regardless of provocation. One‐hundred and thirty‐seven collegiate men completed the Narcissistic Personality Inventory followed by a sham aggression paradigm, which afforded them the opportunity shock, or refrain entirely from shocking an ostensible opponent confederate. Participants were identified as “unprovoked aggressors,” “retaliatory aggressors,” or “nonaggressors” contingent on when and if they chose to administer electrical shocks to the confederate. Results indicated that participants who were high on narcissistic traits were more likely to be unprovoked aggressors than their low narcissism counterparts. Results are discussed in relation to threatened egotism theory and call for more research on narcissism, aggression, and the moderating effect of provocation. Aggr.

A New Framework to Understand Social Class in Counseling: The Social Class Worldview Model and Modern Classism Theory

Because social class and classism remain elusive constructs in psychology, this 2‐part article first lays the foundation for the Social Class Worldview Model and then the Modern Classism Theory. A case example is used for illustration. The authors also provide counseling applications and recommendations for future research. Debido a que la clase social y el clasismo continuan siendo unos conceptos evasivos en la psicología, este artículo de 2 partes establece una fundación para el Modelo de Cosmovisión de Clase Social y la Teoría Moderna del Clasismo. Se utiliza un caso de ejemplo para su ilustración. Los autores también proporcionan aplicaciones para la consejería y recomendaciones para investigaciónes futuras.     

Patterns of self‐regulation and the Big Five

The authors examined relations between self‐regulatory properties of personality (ego‐control and ego‐resilience) and the Big Five. Ego‐control and ego‐resilience were independent predictors of each Big Five dimension. Additionally, cluster analysis suggested four replicable ‘types’. Participants in the first (largest) cluster reported the highest levels of resilience and moderately low levels of control. The second cluster reported above‐average resilience and high control. The third cluster reported below‐average resilience and extremely low control. The final cluster reported very low resilience and high control. The four clusters differed systematically in their Big Five profiles. These findings suggest that self‐regulatory processes are co‐ordinated with other basic personality dimensions, and attest to the utility of conducting both variable‐centred and person‐centred analyses.
