A prelearning manipulation falsifies a pure associational deficit account of retrieval shift during skill acquisition

ABSTRACT

Older adults adopt memory-based response strategies during consistent practice more slowly and less completely than younger adults. In two experiments, participants either prelearned all, half, or none of the noun-pair stimuli prior to the completion of a standard noun-pair lookup task. Higher proportions of prelearning generally led to a faster and more complete strategic shift from visual scanning to memory retrieval during the lookup task, and a strong prelearning criterion for all items eliminated the age-related slowing of retrieval shift. However, the 50% prelearned condition resulted in strategy shift that was inconsistent with simple mechanistic associative learning, revealing a strategic set that was retrieval-avoidant in older adults.     

Latent self-oriented and socially prescribed perfectionism: Tests of factorial,convergent, and discriminant validity using self- and informant reports

Using latent variables for self-oriented perfectionism (i.e., demanding perfection of oneself) and socially prescribed perfectionism (i.e., perceiving others are demanding perfection of oneself) has advantages. However, few studies have specifically examined the psychometric properties of these latent variables. The present study addresses this shortcoming by testing the factorial, convergent, and discriminant validity of self-oriented and socially prescribed perfectionism latent variables using self- and informant reports. It was hypothesized that (a) the factor structure of the self-oriented and socially prescribed perfectionism latent variables would be supported, (b) self- and informant reports would moderately converge, and (c) the self-oriented and socially prescribed perfectionism latent variables would be discriminable. A sample of 242 undergraduate women and 378 informants (218 mothers, 160 fathers) was recruited. Undergraduate women completed self-reports, and mothers and fathers completed informant reports. Results were consistent with hypotheses, thereby supporting (a) the factorial validity of the self-oriented and socially prescribed latent variables using self- and informant reports, (b) the convergent validity of the self-oriented and socially prescribed latent variables via moderately to strongly correlated self- and informant reports, and (c) the discriminant validity of the self-oriented and socially prescribed perfectionism latent variables. Findings suggest research using these latent variables is warranted.     

Perfectionistic self-presentation, socially prescribed perfectionism, and suicide in youth: a test of the perfectionism social disconnection model

The role of interpersonal components of perfectionism in suicide outcomes among youth was assessed and the Perfectionism Social Disconnection Model (PSDM) was tested by determining whether the links between socially prescribed perfectionism (SPP) and perfectionistic self-presentation (PSP) and suicide outcomes are mediated by experiences of social disconnection, as indicated by social hopelessness and being bullied. PSP, trait perfectionism, suicide outcomes, and experiences of being bullied and social hopelessness were measured in 152 psychiatric outpatient children and adolescents. Correlational tests confirmed that PSP and SPP were associated with suicide outcomes and these interpersonal perfectionism components were associated significantly with bullying and social hopelessness. Support was also obtained for the PSDM. The relationship between the PSP facets, particularly nondisplay of imperfections, and suicide outcomes were mediated by being bullied. Additionally, the relationship between all interpersonal components of perfectionism and suicide risk was mediated by social hopelessness. Theoretical and clinical implications of interpersonal components of perfectionism and social disconnection in suicide outcomes for youth are discussed.     

Older adults' use of metacognitive knowledge in source monitoring: spared monitoring but impaired control

While episodic memory declines with age, metacognitive monitoring is spared. The current study explored whether older adults can use their preserved metacognitive knowledge to make source guesses in the absence of source memory. Through repetition, words from two sources (italic vs. bold text type) differed in memorability. There were no age differences in monitoring this difference despite an age difference in memory. Older adults used their metacognitive knowledge to make source guesses but showed a deficit in varying their source guessing based on word recognition. Therefore, older adults may not fully benefit from metacognitive knowledge about sources in source monitoring.     

Reformulating and testing the perfectionism model of binge eating among undergraduate women: a short-term, three-wave longitudinal study

The perfectionism model of binge eating (PMOBE) is an integrative model explaining why perfectionism is related to binge eating. This study reformulates and tests the PMOBE, with a focus on addressing limitations observed in the perfectionism and binge-eating literature. In the reformulated PMOBE, concern over mistakes is seen as a destructive aspect of perfectionism contributing to a cycle of binge eating via 4 binge-eating maintenance variables: interpersonal discrepancies, low interpersonal esteem, depressive affect, and dietary restraint. This test of the reformulated PMOBE involved 200 undergraduate women studied using a 3-wave longitudinal design. As hypothesized, concern over mistakes appears to represent a vulnerability factor for binge eating. Bootstrapped tests of mediation suggested concern over mistakes contributes to binge eating through binge-eating maintenance variables, and results supported the incremental validity of the reformulated PMOBE beyond perfectionistic strivings and neuroticism. The reformulated PMOBE also predicted binge eating, but not binge drinking, supporting the specificity of this model. The reformulated PMOBE offers a framework for understanding how key contributors to binge eating work together to generate and to maintain binge eating.     

Individual and Family Contributions to Depressive Symptoms in African American Children with Sickle Cell Disease

Depressive disorders in children with chronic illnesses have received little attention despite some evidence suggesting that these children experience increased psychological difficulties as a result of their medical condition. Most of the research on depressive disorders among children has been conducted primarily with Caucasian youth, limiting generalizability to ethnically diverse populations. Further, even less research exists on depressive disorders among African American children with Sickle Cell Disease (SCD) and for African American youth from lower socioeconomic status who are at greater risk for depressive disorders. This paper is an extensive review of the major studies conducted on depression and psychosocial aspects of SCD in African American children. The Transactional Stress and Coping model is provided as a conceptual framework. Following the review, clinical and research implications are provided, as well as an illustration of a psychoeducational family intervention with an African American child who has SCD and internalizing behaviors.     

Revitalizing Narcissistic Perfectionism: Evidence of the Reliability and the Validity of an Emerging Construct

Theorists have long speculated about narcissistic perfectionism—an outwardly directed need for perfection marked by grandiosity, entitlement, and lofty expectations for others. This study provides evidence of reliability and predictive validity for an emerging model of narcissistic perfectionism using two waves of measurement and multiple data sources (self-report and informant-report) in a sample of 155 undergraduate students. As hypothesized, confirmatory factor analysis showed manifest indicators of narcissistic perfectionism cohered together as a constellation of traits while showing reliability and factorial validity across time and source. Hierarchical multiple regression indicated narcissistic perfectionism uniquely and incrementally predicted anger beyond competing measures of other-oriented perfectionism and narcissism. Informant-reports of narcissistic perfectionism uniquely predicted anger beyond self-reports. These results offer promising empirical support for the often discussed, but seldom tested, concept of narcissistic perfectionism.
