A strategy disruption component to retrieval-induced forgetting

Retrieval-induced forgetting refers to a paradoxical occurrence wherein the act of remembering some material disrupts the retrieval of other, related material (see, e.g., M. C. Anderson, R. A. Bjork, & E. L. Bjork, 1994). This effect is generally accounted for in terms of inhibitory processes. Across three experiments, we test the inhibitory account of retrieval-induced forgetting, as well as whether there may be a strategy disruption component to the effect. In our first two experiments, we manipulate which items individuals are cued to recall during retrieval practice and demonstrate that retrieval-induced forgetting can be neutralized when those items do not interfere with the individual's retrieval strategy. In the third experiment, we confirm this finding with a different set of stimuli. These results are inconsistent with a purely inhibitory account of retrieval-induced forgetting, and we discuss implications for inhibition theory and strategy disruption in light of these and other findings.     

Children of alcoholics, negative life events, and early experimentation with drugs

Questionnaires were completed by sixth-grade students and their parents in order to assess differences between children of alcoholics (COAs) and their peers, as well as the relations between family environment and children's experimentation with alcohol, drugs, and tobacco. Social competence and problematic behavior were also explored. The best predictors of early experimentation with alcohol, drugs, and tobacco were the experience of negative life events, family conflict, and lack of family cohesion, but not COA status per se. Differences were found between COAs and non-COAs in respect to family structure, parent education levels, and family environment. COAs were found to be significantly more likely than their peers to experiment with tobacco, but not alcohol or drugs. They also had a tendency to engage more frequently in delinquent behavior. Recommendations for future research and implications for preventive activities are discussed.     

Trust in information mediates the relationship between political orientation and perceptions of the COVID-19 pandemic

The past few decades have experienced a decline in the use of traditional news sources as an increasing number of individuals rely on social media for information. Although this change has made it easier to obtain information, individuals often selectively expose themselves to information that confirms their beliefs. The current study examined if this pattern could explain political perceptions during the COVID-19 pandemic. Based on past research, it would be expected that liberals and conservatives would hold differing views of the COVID-19 pandemic. Republicans downplayed the pandemic and were more likely to consider it a hoax, while Democrats exaggerated the pandemic and were more likely to advocate for excessive measures. In this study, we collected two samples at different points during the pandemic in which we asked participants to indicate their political ideology, their perception of the COVID-19 pandemic, and the sources of information that they trusted. Our results indicated that trust in information sources mediated the relationship between political ideology and perceptions of the pandemic, suggesting that the informational sources that an individual trusted was a factor in determining perceptions of the COVID-19 pandemic.     

Intolerance of uncertainty and novelty facilitated extinction: The impact of reinforcement schedule

Individuals who score high in intolerance of uncertainty (IU) display reduced threat extinction. Recently, it was shown that replacing threat associations with novel associations during extinction learning (i.e., presenting a novel tone 100% of the time) can promote threat extinction retention in individuals with high IU. This novelty facilitated extinction (NFE) effect could be driven by the tone's novelty or reliability. Here, we sought to address this question by adjusting the reliability of the novel tone (i.e., the reinforcement rate) during NFE. We measured skin conductance response during an associative learning task in which participants (n = 92) were assigned to one of three experimental groups: standard extinction, NFE 100% reinforcement, or NFE 50% reinforcement. For standard extinction, compared to NFE 100% and 50% reinforcement groups, we observed a trend for greater recovery of the conditioned response during extinction retention. Individuals with high IU relative to low IU in the standard extinction group demonstrated a larger recovery of the conditioned response during extinction retention. These findings tentatively suggest that NFE effects are driven by the novelty rather than the reliability of the new stimulus. The implications of these findings for translational and clinical research in anxiety disorder pathology are discussed.     

My Eyes Are Up Here: The Nature of the Objectifying Gaze Toward Women

Although objectification theory suggests that women frequently experience the objectifying gaze with many adverse consequences, there is scant research examining the nature and causes of the objectifying gaze for perceivers. The main purpose of this work was to examine the objectifying gaze toward women via eye tracking technology. A secondary purpose was to examine the impact of body shape on this objectifying gaze. To elicit the gaze, we asked participants (29 women, 36 men from a large Midwestern University in the U.S.), to focus on the appearance (vs. personality) of women and presented women with body shapes that fit cultural ideals of feminine attractiveness to varying degrees, including high ideal (i.e., hourglass-shaped women with large breasts and small waist-to-hip ratios), average ideal (with average breasts and average waist-to-hip ratios), and low ideal (i.e., with small breasts and large waist-to-hip ratios). Consistent with our main hypothesis, we found that participants focused on women’s chests and waists more and faces less when they were appearance-focused (vs. personality-focused). Moreover, we found that this effect was particularly pronounced for women with high (vs. average and low) ideal body shapes in line with hypotheses. Finally, compared to female participants, male participants showed an increased tendency to initially exhibit the objectifying gaze and they regarded women with high (vs. average and low) ideal body shapes more positively, regardless of whether they were appearance-focused or personality-focused. Implications for objectification and person perception theories are discussed.     

Against Fallibilism

In this paper I argue for a doctrine I call ‘infallibilism’, which I stipulate to mean that If S knows that p, then the epistemic probability of p for S is 1. Some fallibilists will claim that this doctrine should be rejected because it leads to scepticism. Though it's not obvious that infallibilism does lead to scepticism, I argue that we should be willing to accept it even if it does. Infallibilism should be preferred because it has greater explanatory power than fallibilism. In particular, I argue that an infallibilist can easily explain why assertions of ‘p, but possibly not-p’ (where the ‘possibly’ is read as referring to epistemic possibility) is infelicitous in terms of the knowledge rule of assertion. But a fallibilist cannot. Furthermore, an infallibilist can explain the infelicity of utterances of ‘p, but I don't know that p’ and ‘p might be true, but I'm not willing to say that for all I know, p is true’, and why when a speaker thinks p is epistemically possible for her, she will agree (if asked) that for all she knows, p is true. The simplest explanation of these facts entails infallibilism. Fallibilists have tried and failed to explain the infelicity of ‘p, but I don't know that p’, but have not even attempted to explain the last two facts. I close by considering two facts that seem to pose a problem for infallibilism, and argue that they don't.     

Psychopathological and Behavior Impairments in Williams-Beuren Syndrome: The Influence of Gender,Chronological Age,and Cognition

The aim of this study was to explore psychopathological and behavior impairments in Williams-Beuren syndrome (WBS) by focusing on individual differences rather than group tendencies. Parent/Guardian ratings on the Child Behavior Checklist were analyzed in order to examine the influence of gender, chronological age, and cognitive abilities on psychopathological impairment within WBS. In line with predictions, and consistent with cognitive heterogeneity in WBS, psychopathological and behavioral abnormalities were variable, with gender and specific cognitive abilities making significant and independent contributions to this variance. For gender, females were significantly more likely than males with WBS to display difficulties with externalizing problems. For specific cognitive abilities, those cognitive functions characteristic of the classic WBS cognitive profile (a strength in verbal skills and a weakness in spatial skills) related to significantly greater internalizing difficulties. Future studies should explore underlying genetic and neurological differences in individuals with WBS in order to help explain the variability in psychopathological and cognitive functions.
