Cognitive control beliefs and cognitive functioning in mid- to late-life.

OBJECTIVES: Older adults experience age-related cognitive declines and often feel as if the severity of these declines is out of their control. Recent research suggests, though, that control beliefs may be related to less age-related declines. The aim of the current study was to investigate cognitive domain-specific control beliefs and the link between those cognitive control beliefs and cognitive functioning among a nationwide sample of adults (N = 3,670), as well as to explore whether cognitive control beliefs moderated the relationship between age and cognitive functioning. METHOD: The aims were addressed using data from the national Midlife in the United States study (MIDUS II). Cognitive functioning was assessed using the Brief Test of Adult Cognition by Telephone (BTACT), and cognitive control beliefs were assessed with the Personality in Intellectual Aging Contexts (PIC) Inventory Control Scales. RESULTS: Regression analyses revealed that adults with higher control beliefs demonstrated better cognitive functioning. Moderation analyses indicated cognitive control beliefs moderated the relationship between age and executive functioning, but not the association between age and episodic memory. CONCLUSION: Results suggested that the relationship between age and executive functioning was weaker at high levels of cognitive control beliefs. Future research should establish the directionality of the effect between cognitive control beliefs and cognition and investigate the association between control beliefs and cognition in samples at higher risk for substantial cognitive decline, including the oldest-old.

Gray (Literature) Matters: Evidence of Selective Hypothesis Reporting in Social Psychological Research.

Selective reporting practices (SRPs)-adding, dropping, or altering study elements when preparing reports for publication-are thought to increase false positives in scientific research. Yet analyses of SRPs have been limited to self-reports or analyses of pre-registered and published studies. To assess SRPs in social psychological research more broadly, we compared doctoral dissertations defended between 1999 and 2017 with the publications based on those dissertations. Selective reporting occurred in nearly 50% of studies. Fully supported dissertation hypotheses were 3 times more likely to be published than unsupported hypotheses, while unsupported hypotheses were nearly 4 times more likely to be dropped from publications. Few hypotheses were found to be altered or added post hoc. Dissertation studies with fewer supported hypotheses were more likely to remove participants or measures from publications. Selective hypothesis reporting and dropped measures significantly predicted greater hypothesis support in published studies, supporting concerns that SRPs may increase Type 1 error risk.

Comparisons of Intelligence and Behavior in Children With Fetal Alcohol Spectrum Disorder and ADHD.

OBJECTIVE: Children with fetal alcohol spectrum disorder (FASD) can easily be misdiagnosed as having ADHD. METHOD: A total of 164 children were compared on cognitive and behavioral measures for four groups of children: FASD, ADHD, FASD + ADHD, and other neuropsychological disorders. RESULTS: The ADHD group was not significantly different from the "other diagnosis" group on any of the measurements. The children with FASD were found to perform significantly worse than ADHD on externalizing problems, Full-Scale IQ, and indices of Verbal Comprehension, Perceptual Reasoning, and Working Memory. The comorbid FASD + ADHD group was significantly weaker than ADHD on verbal comprehension measures. The FASD children demonstrated significantly higher levels of atypicality and aggression relative to ADHD, and the FASD + ADHD group demonstrated significantly higher levels of hyperactivity and withdrawal relative to ADHD. CONCLUSION: These results indicate that children with FASD display a differential behavioral and cognitive profile that is significantly poorer than children with ADHD and other types of neuropsychological disorders.
