Understanding boundary extension: Normalization and extension errors in picture memory among adults and boys with and without Asperger's syndrome

Boundary extension is the tendency for people to “remember” information that fell outside a picture's boundaries. We used a novel test of boundary extension to provide absolute estimates of the magnitude of extension errors and of the degree to which people are influenced by the way a picture is presented at the time of testing. Participants were shown photographs on a computer and subsequently allowed to adjust their magnification to match the size they remembered. The test produced reliable boundary extension of around 11% in adults and large influences of initial test size. In a second experiment we tested boys diagnosed with Asperger's syndrome and matched controls. Both groups demonstrated boundary extension comparable to that observed in adults but greater effects of initial test size. High performance IQ in Asperger's was linked with high levels of boundary extension, while for the matched control group the opposite pattern was obtained.     

Can Perceptions of Supervisor-Related Ethical Climate Influence How High-Impression Managers Admit Past Unethical Behavior?

In this study, we investigated how the perceptions of ethical climate as it relates to supervisor behavior and impression management are related to admission of past unethical behavior in a sample of Canadian Army personnel. We expected that among respondents who perceive less ethical supervisor-related climate, the relationship between Impression Management (IM) and the admission of past unethical behavior should be significant and positive. In contrast, among respondents who perceive a more ethical supervisor-related climate, the relationship between IM and self-report past unethical behavior should be weak or nonsignificant, and the frequency of admission of past unethical behavior should be low. Although moderation occurred, it was not as hypothesized. IM predicted admission of having obeyed, or witnessed others obey an unlawful command when perceptions of supervisor-related ethical climate were low, and not when perceptions of supervisor-related ethical climate were high. However, higher (vs. lower) impression managers admitted less past unethical behavior, regardless of their perceptions of supervisor-related ethical climate. These results suggest that high impression managers do not admit to having obeyed or witnessed others obey an unlawful command in the past, regardless of their perceptions of the ethical climate as it relates to supervisor behavior.     

Reduced Verbal Memory Retention is Unrelated to Sleep Disturbance During Pregnancy

This study investigated episodic and procedural memory retention in early and late pregnancy and whether memory retention was related to sleep disruption. Twenty‐six women in the third trimester of pregnancy, 20 women in the first trimester of pregnancy, and 24 non‐pregnant controls were administered a battery of verbal and visual episodic memory tasks and two procedural memory tasks before undergoing an overnight sleep study. Memory retention was assessed the following morning. Results indicated that as compared with controls, both pregnant groups had reduced retention in verbal episodic memory but were unimpaired on visual and procedural memory tasks. The pregnant women also demonstrated significant disruption of sleep patterns. Reduced verbal memory retention during pregnancy was not attributable to any measure of sleep; however, small correlations between some indices of sleep and memory do not allow full dismissal of the sleep‐dependent memory consolidation hypothesis.     

Discussion increases efficacy when training accurate perception of patients' affect

Patients benefit when their healthcare providers accurately recognize their affect. The efficacy of three short‐term training components, practice, practice with feedback, and discussion with practice and feedback, to improve accuracy for judging patients' affect was experimentally assessed. Undergraduate participants were randomly assigned in pairs to one of the training conditions or an untrained control condition and the effect of training was measured using the Test of Accurate Perception of Patients' Affect (TAPPA). Participants were significantly more accurate on the TAPPA in the discussion with feedback and practice condition compared with the control condition. There was a significant linear trend in accuracy across training elements. Results suggest that a 40‐min discussion with feedback and practice training can significantly improve interpersonal accuracy.     

The impact of inhibition capacities and age on number–space associations

Numerical and spatial representations are tightly linked, i.e., when doing a binary classification judgment on Arabic digits, participants are faster to respond with their left/right hand to small/large numbers, respectively (Spatial-Numerical Association of Response Codes, SNARC effect, Dehaene et al. in J Exp Psychol Gen 122:371–396, 1993). To understand the underlying mechanisms of the well-established SNARC effect, it seems essential to explore the considerable inter-individual variability characterizing it. The present study assesses the respective roles of inhibition, age, working memory (WM) and response speed. Whereas these non-numerical factors have been proposed as potentially important factors to explain individual differences in SNARC effects, none (except response speed) has so far been explored directly. Confirming our hypotheses, the results show that the SNARC effect was stronger in participants that had weaker inhibition abilities (as assessed by the Stroop task), were relatively older and had longer response times. Interestingly, whereas a significant part of the age influence was mediated by cognitive inhibition, age also directly impacted the SNARC effect. Similarly, cognitive inhibition abilities explained inter-individual variability in number–space associations over and above the factors age, WM capacity and response speed. Taken together our results provide new insights into the nature of number–space associations by describing how these are influenced by the non-numerical factors age and inhibition.     

Characteristics and Effects of the Co-parenting Alliance between Incarcerated Parents and Child Caregivers

We examined co-parenting alliance based on information provided by 57 incarcerated parents and their corresponding child caregivers who took part in the Messages Project, in which incarcerated parents video recorded greetings to children that were then mailed home. We assessed perceptions of co-parenting alliance, measured by the Parenting Alliance Measure, and levels of child contact from both parents and caregivers. We also observed expressions of positive and negative attitudes that prisoners expressed regarding the home caregiver during the video recording. Incarcerated parents reported more frequent phone contact with children and more frequent letter-writing to children than did home caregivers. Incarcerated parents likewise reported higher levels of co-parenting alliance with the home caregiver in comparison to the assessment of co-parenting alliance reported by the home caregiver. Among children observing the video recorded message, a more positive co-parenting alliance between their parent and home caregiver was associated with increased positive mood. More frequent displays of negative attitudes toward caregivers during the recordings were associated with more negative mood indicators among children. Results suggest the importance of a strong co-parenting alliance between incarcerated parents and home caregivers, but imply that incarcerated parents may have a more optimistic view of their connection home than is the case for collaborating caregivers.     

Stepparents and Parenting Stress: The Roles of Gender,Marital Quality,and Views about Gender Roles

Previous research suggests that stepparenting can be stressful, although the mechanisms that contribute to the experience of parenting stress in stepfamilies are less clear. This study examines gender, marital quality, and views about gendered family roles as correlates of parenting stress among 310 stepmothers, stepfathers, and biological mothers and fathers. Findings suggest that stepparents, and especially stepmothers, experience higher levels of parenting stress than biological parents. Findings also suggest that less traditional views about gendered family roles and higher dyadic adjustment are associated with lower parenting stress for stepparents, particularly in combination. Stepparents reporting both of these protective factors were indistinguishable in terms of parenting stress from biological parents. These findings indicate potential pathways to mitigate the stress associated with stepparenting.     

Core Dimensions of Personality Broadly Account for the Link from Perceived Social Support to Symptoms of Depression and Anxiety

Specific personality traits and poor social support are risk factors for anxiety and depression. Little work, however, has considered the effects of social support and personality on these aspects of psychopathology simultaneously. We examined whether perceived social support mediates the effects of core personality domains on symptoms of anxiety and depression. Measures of personality (based on the Five‐Factor Model [FFM]), perceived social support, and symptoms of depression and anxiety were collected in a large Dutch adult population‐based sample (n = 555), and, except for depression symptoms, in an independent U.S. adult population‐based sample (n = 511). Path modeling was used to test the effects of FFM traits on symptoms of depression and anxiety, with and without the mediation of perceived social support. Social support showed no link to symptoms of anxiety and only modest links to symptoms of depression when controlling for the FFM traits. Neuroticism had the strongest effect on symptoms of both depression and anxiety, with Extraversion also showing links to symptoms of depression. Social support has limited influence on symptoms of depression, and no effects on anxiety, over and above the effects of personality. Links between social support and anxiety/depression may largely reflect influences of Neuroticism and Extraversion.     

The Effect of Response Bias on the Personality Inventory for DSM–5 (PID–5)

Valid self-report assessment of psychopathology relies on accurate and credible responses to test questions. There are some individuals who, in certain assessment contexts, cannot or choose not to answer in a manner typically representative of their traits or symptoms. This is referred to, most broadly, as test response bias. In this investigation, we explore the effect of response bias on the Personality Inventory for DSM–5 (PID–5; Krueger, Derringer, Markon, Watson, & Skodol, 2013 Krueger, R. F., Derringer, J., Markon, K. E., Watson, D., & Skodol, A. E. (2013). The Personality Inventory for DSM–5 (PID–5)–Adult (Full version). Washington, DC: American Psychiatric Association. [Google Scholar]), a self-report instrument designed to assess the pathological personality traits used to inform diagnosis of the personality disorders in Section III of DSM–5. A set of Minnesota Multiphasic Personality Inventory Restructured Form (MMPI–2–RF; Ben-Porath & Tellegen, 2008 Tellegen, A., & Ben-Porath, Y. S (2008). MMPI–2–RF technical manual. Minneapolis: University of Minnesota Press. [Google Scholar]/2011 Ben-Porath, Y. S., & Tellegen, A. (2011). MMPI–2–RF manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press. (Original work published 2008) [Google Scholar]) validity scales, which are used to assess and identify response bias, were employed to identify individuals who engaged in either noncredible overreporting (OR) or underreporting (UR), or who were deemed to be reporting or responding to the items in a “credible” manner—credible responding (CR). A total of 2,022 research participants (1,587 students, 435 psychiatric patients) completed the MMPI–2–RF and PID–5; following protocol screening, these participants were classified into OR, UR, or CR response groups based on MMPI–2–RF validity scale scores. Groups of students and patients in the OR group scored significantly higher on the PID–5 than those students and patients in the CR group, whereas those in the UR group scored significantly lower than those in the CR group. Although future research is needed to explore the effects of response bias on the PID–5, results from this investigation provide initial evidence suggesting that response bias influences scale elevations on this instrument.
