Negative emotionality is linked to unfavorable life outcomes, but studies have yet to examine negative emotionality of parents and children as predictors of children's problem behaviors and negative emotion word use in everyday life. This study used a novel naturalistic recording device called the Electronically Activated Recorder to investigate the separate and interactive influences of parent...

This study examined associations between temperament at age 3 and depressotypic cognitive styles at age 7 in a community sample of children. Sixty-four preschool aged children were assessed for positive emotionality (PE) and negative emotionality (NE) using a standardized battery of laboratory tasks and naturalistic home observations. At follow-up 4 years later, the children completed laborator...

Abstract Why would decision makers (DMs) adopt heuristics, priors, or in short “habits” that prevent them from optimally using pertinent information—even when such information is freely-available? One answer, Herbert Simon’s “procedural rationality” regards the question invalid: DMs do not, and fact cannot, process an optimal fashion. For Simon, habits are primitives, where humans ready to repl...

Data regarding children's shyness and emotionality were collected at three time points, two years apart (T1: N = 214, M = 6.12 years; T2: N = 185, M = 7.67 years; T3: N = 185, M = 9.70 years), and internalizing data were collected at T1 and T3. Relations among parent-rated shyness, emotionality (parent- and teacher-rated anger, sadness, and positive emotional intensity [EI]), and mother-rated i...

Who do we see when envisioning our "past self" and "future self"? Extant research finds a motivation to perceive improvement over time, such that past selves are seen as worse versions, and future selves as better versions, of current selves. However, the broader components comprising "worse" or "better" beyond domain-specific achievement (e.g., "Last year I failed at dieting, but next year I'l...

BACKGROUND There are no strong and consistent predictors of dietary habits although some associations have been shown with psychological factors. The purpose of the present study was to examine the relationships between the rationality and anti-emotionality (R/A) personality and dietary consumption in a Japanese community. METHODS The Takayama study is a community-based cohort study on diet a...

BACKGROUND It has been estimated that approximately 25% of all breast cancers in women can be explained by currently recognized somatic (i.e., hereditary and physiologic) risk factors. It has also been hypothesized that psychological factors may play a role in the development of breast cancer. PURPOSE We investigated the extent to which personality factors, in addition to somatic risk factors...

The concept of life-stage orientation is proposed. Youth is a period of time characterised by strong feelings and emotions, but weak reasoning and cognitive skill. Conversely, adulthood is characterised by strong rationality, but weak emotionality. Two studies revealed that merely bringing these concepts to mind changes real-time feelings and behaviour. Participants who were instructed to act l...

Bounded reasoning about rationality can have important implications for behavior. These bounds are typically viewed as an artifact of limits in the ability to engage in interactive reasoning, i.e., to reason through “I think, you think, I think, etc ...” However, in principle, these bounds need not be determined by limits in ability. This paper develops a novel identification strategy to show t...
