Understanding expert testimony on child sexual abuse denial after New Jersey v. J.L.G.: Ground truth,disclosure suspicion bias,and disclosure substantiation bias

The New Jersey Supreme Court held in New Jersey v. J.L.G. (2018) that experts can no longer explain to juries why sexually abused children might deny abuse. The court was influenced by expert testimony that “methodologically superior” studies find lower rates of denial. Examining the studies in detail, we argue that the expert testimony was flawed due to three problems with using child disclosure studies to estimate the likelihood that abused children are reluctant to disclose abuse: the ground truth problem, disclosure suspicion bias, and disclosure substantiation bias. Research identifying groups of children whose abuse can be proven without reliance on disclosure reveals that denial of sexual abuse is common among abused children.     

What are the Marital Problems of Happy Couples? A Multimethod,Two-Sample Investigation

How couples handle marital conflict may depend on what issues they are facing, as some issues may be more difficult to resolve than others. What is unclear, however, is what issues happy couples face and how these issues may be different for couples depending on their developmental stage. To explore this possibility, the current study used both self-reports and observations drawn from two separate samples of happily married couples—one early in middle adulthood (N = 57 couples; average marital duration = 9 years) and one in older adulthood (N = 64 couples; average marital duration = 42 years). Results indicated that all issues were relatively minor, but early middle-aged couples reported more significant problems than did older couples. As to determining the most salient topic for happy couples, it depended on the spouses’ gender, developmental stage, and how salience was assessed (i.e., highest rated issue vs. most discussed issue). Only moderate links were found between what happy couples said was their most serious concern and what they actually tried to resolve during observations of marital problem-solving, but there were differences in how spouses behaved based on the proportion of their time discussing certain topics. Findings suggest that more attention should be devoted to understanding what marital issues happy couples discuss and why, as doing so may reveal how couples maintain their marital happiness.     

Under what conditions do U.S. and Taiwanese late adolescents feel victimized by their peers?

This study investigates whether cultural differences exist between the ways U.S. and Taiwanese college students perceive peer victimization using both an experimental vignette method and an open‐ended question format. A total of 1,125 college students (53% female) from the United States (n = 535) and Taiwan (n = 590) read and responded to vignettes which depicted peer interactions in the college context. The peer interactions varied along three factors expected to be associated with differentiating victimization from affiliative teasing: hostility, playfulness, and relationship closeness. Controlling for individual factors of sex, prior victimization, prior teasing, and emphasis on interpersonal harmony, students perceived more victimization when both hostility and a lack of playfulness were present. Culture interacted with the situational factors such that both hostility and lack of playfulness were stronger predictors of perceived victimization for Taiwanese than for U.S. college students. In open‐ended responses about sensitive topics, “Ability and academic performance” and “Self/thoughts/characters/habits” were more indicative of victimization for Taiwanese college students. “Health and disability” was more salient as indicative of victimization for U.S. college students. Findings from this study are among the first to evaluate signals of peer victimization with a cultural comparison; they can be used to inform victimization intervention programs or socioemotional curriculums in late adolescence to be culturally relevant.     

Children's understanding of habitual behaviour

Research into the development of Theory of Mind (ToM) has shown how children from a very early age infer other people's goals. However, human behaviour is sometimes driven not by plans to achieve goals, but by habits, which are formed over long periods of reinforcement. Habitual and goal‐directed behaviours are often aligned with one another but can diverge when the optimal behavioural policy changes without being directly reinforced (thus specifically hobbling the habitual learning strategy). Unlike the flexibility of goal‐directed behaviour, rigid habits can cause agents to persist in behaviour that is no longer adaptive. In the current study, all children predict agents will tend to behave consistently with their goals, but between the ages of 5 and 10, children showed an increasing understanding of how habits can cause agents to persistently take suboptimal actions. These findings stand out from the typical way the development of social reasoning is examined, which instead focuses on children's increasing appreciation of how others' beliefs or expectations affect how they will act in service of their goals. The current findings show that children also learn that under certain circumstances, people's actions are suboptimal despite potentially ‘knowing better.’     

Focal lung pathology detection in radiology: Is there an effect of experience on visual search behavior?

In radiology, 60% to 80% of diagnostic errors are perceptual. The use of more efficient visual search behaviors is expected to reduce these errors. We collected eye-tracking data from participants with different levels of experience when interpreting chest X-rays during the completion of a pathology-detection task. Eye-tracking measures were assessed in the context of three existing visual search theories from the literature to understand the association between visual search behavior and underlying processes: the long-term working memory theory, the information-reduction hypothesis, and the holistic model of image perception. The most experienced participants (radiology residents) showed the highest level of performance, albeit their visual search behaviors did not differ from the intermediate group. This suggests that radiology residents better processed the represented information on the X-ray, using a visual search strategy similar to the intermediate group. Since similar visual search resulted in more information extraction in the radiology residents compared with the intermediates, we suggest that this result might support the long-term working memory theory. Furthermore, compared with novices, intermediates and radiology residents fixated longer on areas that were more important to avoid missing any pathology, which possibly confirms the information-reduction hypothesis. Finally, the larger distances between fixations observed in more experienced participants could support the holistic model of image perception. In addition, measures of generic skills were related to a lower time cost for switching between global and local information processing. Our findings suggest that the three theories may be complementary in chest X-ray interpretation. Therefore, a unified theory explaining perceptual-cognitive superiority in radiology is considered.

     

Who distinguishes between sinners and sins at the implicit level of awareness?

Several researchers have investigated the possibility that people indeed can love individuals who are engaged in behaviors that are considered unacceptable. In the present research, the authors evaluated the possibility that people distinguish between presumably sinful persons and presumably sinful behaviors at a cognitive level that does not involve conscious intent and awareness: the implicit (nonconscious) level of awareness. Participants performed a speeded-response task, the Implicit Association Test. Results indicated that participants were able to make such a (person vs. behavior) distinction and that in doing so, they manifested positive implicit evaluations of sinful people relative to sinful actions.     

Environmental context influences visually perceived distance

What properties determine visually perceived space? We discovered that the perceived relative distances of familiar objects in natural settings depended in unexpected ways onthe surrounding visual field. Observers bisected egocentric distances in a lobby, in a hallway, and on an open lawn. Three key findings were the following: (1) Perceived midpoints were too far from the observer, which is the opposite of the common foreshortening effect. (2) This antiforeshortening constant error depended on the environmental setting--greatest in the lobby and hall but nonsignificant on the lawn. (3) Context also affected distance discrimination; variability was greater in the hall than in the lobby or on the lawn. A second experiment replicated these findings, using a method of constant stimuli. Evidently, both the accuracy and the precision of perceived distance depend on subtle properties of the surrounding environment.     

When is being known or adored by romantic partners most beneficial? Self-perceptions, relationship length, and responses to partner's verifying and enhancing appraisals

An experiment tested the hypothesis that relationship length moderates preferences for both verifying and enhancing appraisals from romantic partners, particularly for people with negative self-perceptions. One hundred and three romantically involved couples participated in this research. Participants with both negative and positive self-perceptions were randomly assigned to receive either verifying or enhancing feedback ostensibly created through comparison of their self-ratings and their partner's appraisals. The critical test was for those with negative self-ratings who received verifying feedback. For these participants, results revealed that those in longer relationships felt their partners were seeing the best in them more than did those in shorter relationships, whereas the opposite pattern of results was observed for those who were enhanced. Individuals with negative self-ratings who were verified also reported greater feelings of intimacy in the relationship when in long-term relationships. The importance of relationship length in moderating responses to partner's appraisals is discussed.
