Psychometric Properties of the Child Posttraumatic Cognitions Inventory in a Sample of Brazilian Children

Cognitive models of trauma propose that maladaptive cognitions in children and adolescents are causally implicated in the unfolding and maintenance of posttraumatic response. The objective of this study was to evaluate the psychometric properties of the Child Posttraumatic Cognitions Inventory (CPTCI). The sample included 131 children and adolescents. The psychometric properties of the CPTCI were examined, including reliability and convergent validity. The results showed high internal consistency for both CPTCI total scale (α = .90) and its subscales (CPTCI–PC α = .88 and CPTCI–SW α = .79) and a 2-component solution explaining 37.63% of the variance of CPTCI. Convergent validity evidence was obtained through correlations with the Trauma Symptom Checklist for Children and Children’s Depression Inventory. Findings suggest that CPTCI instruments are reliable and had adequate evidence of validity.     

How "implicit" are implicit color effects in memory?

Processing colored pictures of objects results in a preference to choose the former color for a specific object in a subsequent color choice test (Wippich & Mecklenbr?uker, 1998). We tested whether this implicit memory effect is independent of performances in episodic color recollection (recognition). In the study phase of Experiment 1, the color of line drawings was either named or its appropriateness was judged. We found only weak implicit memory effects for categorical color information. In Experiment 2, silhouettes were colored by subjects during the study phase. Performances in both the implicit and the explicit test were good. Selections of "old" colors in the implicit test, though, were almost completely confined to items for which the color was also remembered explicitly. In Experiment 3, we applied the opposition technique in order to check whether we could find any implicit effects regarding items for which no explicit color recollection was possible. This was not the case. We therefore draw the conclusion that implicit color preference effects are not independent of explicit recollection, and that they are probably based on the same episodic memory traces that are used in explicit tests.     

Color and context: An ERP study on intrinsic and extrinsic feature binding in episodic memory

Episodic memory for intrinsic item and extrinsic context information is postulated to rely on two distinct types of representation: object and episodic tokens. These provide the basis for familiarity and recollection, respectively. Electrophysiological indices of these processes (ERP old-new effects) were used together with behavioral data to test these assumptions. We manipulated an intrinsic object feature (color; Experiment 1) and a contextual feature (background; Experiments 1 and 2). In an inclusion task (Experiment 1), the study-test manipulation of color affected object recognition performance and modulated ERP old-new effects associated with both familiarity and recollection. In contrast, a contextual manipulation had no effect, although both intrinsic and extrinsic information was available in a direct feature (source memory) test. When made task relevant (exclusion task; Experiment 2), however, context affected the ERP recollection effect, while still leaving the ERP familiarity effect uninfluenced. We conclude that intrinsic features bound in object tokens are involuntarily processed during object recognition, thus influencing familiarity, whereas context features bound in episodic tokens are voluntarily accessed, exclusively influencing recollection.

Not wallowing in misery – retractions of negative misinformation are effective in depressive rumination

People often continue to rely on misinformation in their reasoning after they have acknowledged a retraction; this phenomenon is known as the continued-influence effect. Retractions can be particularly ineffective when the retracted misinformation is consistent with a pre-existing worldview. We investigated this effect in the context of depressive rumination. Given the prevalence of depressotypic worldviews in depressive rumination, we hypothesised that depressive rumination may affect the processing of retractions of valenced misinformation; specifically, we predicted that the retraction of negative misinformation might be less effective in depressive ruminators. In two experiments, we found evidence against this hypothesis: in depressive ruminators, retractions of negative misinformation were at least as effective as they were in control participants, and more effective than retractions of positive misinformation. Findings are interpreted in terms of an attentional bias that may enhance the salience of negative misinformation and may thus facilitate its updating in depressive rumination.     

Gender Bias in Asylum Adjudications: Evidence for Leniency toward Token Women

Gender is one of the most frequently studied variables in the literature on judicial decision-making. We add to this literature by hypothesizing that the impact of applicant gender is conditional on the gender balance in a judge’s caseload. We expect that female applicants receive more favorable decisions from judges whose caseload skews strongly male. Analyzing over 40,000 rulings by the Austrian Asylum Court between 2008 and 2013, we find support for direct gender effects for applicants and judges (yet no significant interaction between the two). We also show that gender balance in the caseload is a strong moderator of applicant gender. Judges with predominantly male caseloads are strongly biased toward female applicants, whereas judges facing a gender-balanced set of applicants display hardly any gender bias at all. These findings tackle essential questions of democratic rule of law and human rights. They indicate that applicants’ fundamental rights to a fair and equal trial may have been compromised. We discuss institutional remedies to reduce the potential for gender bias in Austrian asylum adjudication.

     

They Might Be a Liar But They’re My Liar: Source Evaluation and the Prevalence of Misinformation

Even if people acknowledge that misinformation is incorrect after a correction has been presented, their feelings towards the source of the misinformation can remain unchanged. The current study investigated whether participants reduce their support of Republican and Democratic politicians when the prevalence of misinformation disseminated by the politicians appears to be high in comparison to the prevalence of their factual statements. We presented U.S. participants either with (1) equal numbers of false and factual statements from political candidates or (2) disproportionately more false than factual statements. Participants received fact-checks as to whether items were true or false, then rerated both their belief in the statements as well as their feelings towards the candidate. Results indicated that when corrected misinformation was presented alongside equal presentations of affirmed factual statements, participants reduced their belief in the misinformation but did not reduce their feelings towards the politician. However, if there was considerably more misinformation retracted than factual statements affirmed, feelings towards both Republican and Democratic figures were reduced—although the observed effect size was extremely small.     

How Stories in Memory Perpetuate the Continued Influence of False Information

People often encounter information that they subsequently learn is false. Past research has shown that people sometimes continue to use this misinformation in their reasoning, even if they remember that the information is false, which researchers refer to as the continued influence effect. The current work shows that the continued influence effect depends on the stories people have in memory: corrected misinformation was found to have a stronger effect on people's beliefs than information that was topically related to the story if it helped to provide a causal explanation of a story they had read previously. We argue this effect occurs because information that can fill a causal “gap” in a story enhances comprehension of the story event, which allows people to build a complete (if inaccurate) event model that they prefer over an accurate but incomplete event model. This effect is less likely to occur for stories in memory that end in a negative way, presumably because people are more motivated to accurately understand negative outcome events.     

Electrophysiological correlates of exemplar-specific processes in implicit and explicit memory

The present ERP study investigated the retrieval of task-irrelevant exemplar-specific information under implicit and explicit memory conditions. Subjects completed either an indirect memory test (a natural/artificial judgment) or a direct recognition memory test. Both test groups were presented with new items, identical repetitions, and perceptually different but conceptually similar exemplars of previously seen study objects. Implicit and explicit memory retrieval elicited clearly dissociable ERP components that were differentially affected by exemplar changes from study to test. In the indirect test, identical repetitions, but not different exemplars, elicited a significant ERP repetition priming effect. In contrast, both types of repeated objects gave rise to a reliable old/new effect in the direct test. The results corroborate that implicit and explicit memory fall back on distinct cognitive representation and, more importantly, indicate that these representations differ in the type of stimulus information stored. Implicit retrieval entailed obligatory access to exemplar-specific perceptual information, despite its being task irrelevant. In contrast, explicit retrieval proved to be more flexible with conceptual and perceptual information accessed according to task demands.
