Enhanced perceptual priming for neutral stimuli in a traumatic context: A pathway to intrusive memories?

Clinical observations suggest that re-experiencing symptoms are triggered by stimuli that are perceptually similar to those present shortly before the trauma or its worst moments. Two experiments investigated the possible role of perceptual priming in this phenomenon. Volunteers (N = 28, N = 62) watched a series of “traumatic” and neutral picture stories, and completed blurred object identification (priming) and recognition memory tasks. Neutral objects that immediately preceded the “traumatic” stories were more strongly primed, but not better recognised, than objects from neutral stories. Enhanced priming predicted subsequent re-experiencing symptoms. The results support the role of perceptual priming in re-experiencing.     

Sensing the presence of the deceased: A narrative review

Researchers have reported that bereaved people often continue to sense the presence of the deceased. A particular collection of such experiences can be identified as instilling a perception that the deceased person is in some manner present in the company of the bereaved person. The aim of the current review was to synthesise the results on this topic to provide a comprehensive over-view for practitioners working with bereaved people who report these experiences. The studies were reviewed in terms of the nature of the experiences described, the provision of explanatory models to understand the significance of these experiences, describing any culturally specific aspects of these experiences, discussion of the personal impact of having the experiences, and for recommendations of how people who have these experiences can be supported.     

A Study of the SIRS With Severely Traumatized Patients

Clinical research has revealed that traumatized patients often elevate feigning indicators on psychological measures, which raises the possibility that traumatization and concomitant dissociation may lead to misclassifications of malingering. Within the domain of feigned mental disorders, the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, &; Dickens, 1992 Rogers, R., Bagby, R. M. and Dickens, S. E. 1992. Structured Interview of Reported Symptoms professional manual, Odessa, FL: Psychological Assessment Resources.  [Google Scholar]) is a well established measure with excellent reliability and validity across clinical and forensic settings. Although recent studies have demonstrated its effectiveness with outpatient posttraumatic stress disorder (PTSD) samples, the SIRS usefulness with severely traumatized patients remains to be investigated. In this study, we recruited traumatized patients for a within-subjects simulation design in which we asked feigners to convincingly portray themselves as examinees claiming total disabilities. When compared to standard instructions, feigned presentations produced substantial effect sizes. Although the standard SIRS classifications produced moderately high sensitivities (M = .82), the false-positive rates were problematic. To minimize false-positives, we constructed a Trauma Index (TI) from 3 primary SIRS scales that appeared unaffected by severe trauma. Implementation of the TI substantially reduced false-positive rates (M = .09).     

Giving up problem solving

How do people decide to abandon a problem? Participants were presented with unsolvable water jar problems, having been accurately informed of the prior probability of solvability. Across three experiments, we discovered effects of prior probability of solvability and of problem size (number of distinct problem states) on measures of effort and confidence. If a problem is more likely to be solvable and allows more problem states, a problem solver spends longer trying to solve the problem. Giving-up decisions are informed by the same judgments of probability of success and costs of solution that inform move-choice in a rational model of problem solving.     

The effect of cognitive reappraisal on the emotional memory trade-off

Emotional information is often remembered better than neutral information, but this enhancement can come at the cost of memory for non-emotional stimuli presented alongside emotionally salient items. Two encoding-related factors have been proposed to influence the magnitude of this trade-off: The intensity of the affective response to the scenes (which increases the trade-off) and the cognitive control exerted to process the scenes (which decreases the trade-off). The present study examined the relative importance of these two factors by assessing the effect of cognitive reappraisal on the magnitude of the trade-off effect. Cognitive reappraisal refers to the implementation of cognitive strategies to assist a person in changing the intensity of their response to an experience. Thus, reappraisal provides a way to assess both of the factors that are important for the elicitation of the trade-off. The results revealed that when participants were asked to view the scenes, without cognitive reappraisal, a robust memory trade-off occurred. But, when participants were asked to either heighten or decrease their emotional reactions via reappraisal, there was a reduction in the magnitude of the trade-off. These results suggest that the cognitive process of reappraising the scenes is sufficient to reduce the trade-off effect, even when such processing leads to an intensified affective response.     

Establishing the Measurement Invariance of the Very Short Form of the Infant Behavior Questionnaire Revised for Mothers Who Vary on Race and Poverty Status

We examined the measurement invariance of the Infant Behavior Questionnaire Revised–Very Short Form (IBQR–VSF; Putnam, Helbig, Gartstein, Rothbart, &; Leerkes, 2014 Putnam, S. P., Helbig, A. L., Gartstein, M. A., Rothbart, M. K., &; Leerkes, E. (2014). Development and assessment of Short and Very Short Forms of the Infant Behavior Questionnaire–Revised. Journal of Personality Assessment, 96, 445–458. doi:10.1080/00223891.2013.841171[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) in a sample of 470 racially (185 White, 285 African American) and socioeconomically diverse mothers (158 below federal poverty threshold, 296 above federal poverty threshold) of infants. Using multigroup confirmatory factor analysis, we demonstrated configural, full metric, and full scalar invariance demonstrating that the 3-factor structure (negative emotionality, positive affectivity/surgency, orienting/regulatory capacity), pattern of item loadings, and item means were comparable for White and African American mothers, and for poor and not poor mothers. In addition, we demonstrated full error invariance across racial groups and partial error variance invariance across poverty status, demonstrating that item reliability was comparable for White and African American mothers, and both those above and below the poverty line (with the exception of a subset of items). Thus, the IBQR–VSF appears appropriate for use in racially and socioeconomically diverse samples.     

The Aggressiveness of Playful Arguments

Some people report that they argue for play. We question whether and how often such arguments are mutually entertaining for both participants. Play is a frame for arguing, and the framing may not always be successful in laminating the eristic nature of interpersonal argumentation. Previous research and theory suggest that playfulness may be associated with aggression. Respondents (N = 199) supplied self-report data on their arguing behaviors and orientations. We found support for the hypothesis that self-reported playfulness and aggression are directly associated. We found less evidence for our hypothesized inverse association between self-reported playfulness and indices of cooperation and avoidance. Self-reports of playfulness are not significantly associated with expert coders’ ratings of either playfulness or aggressiveness. The claim that an argument is playful should be met with skepticism, although playful arguments are possible.     

Mental control and visual illusions: Toward explaining race-biased weapon misidentifications

People are biased to misidentify harmless objects as weapons when the objects are associated with African Americans (Payne, 2001). Two studies examined the processes underlying this bias. The illusory perception hypothesis argues that stereotypes alter the subjective construal of the object. In contrast, the executive failure hypothesis argues that even when perception of the item is intact, misidentifications can result from failures to control responses. Immediately after making an error, participants were able to accurately express that they had made a mistake via confidence ratings (Experiment 1) and by correcting their judgment (Experiment 2). Subjective confidence judgments were extremely well calibrated to accuracy, and participants virtually never believed their own mistakes. Conditions likely to create errors through both illusions and control failures are discussed.
