Interactions Between Mental Models Used in Categorization and Experiential Knowledge of Specific Cases

Three experiments investigated the relation between recognition of specific cases and categorization in a double-task paradigm that requires both types of information (Estes, 1986b). Results indicated that recognition and categorization were often affected differently by experimental variables. However, mental models used in categorization sometimes hindered development of experiential (case-based) knowledge, leading to lower levels of case recognition and suboptimal categorization performance. When mental models were complex or difficult to discover (non-salient), subjects often used experiential knowledge to classify into categories, resulting in dependence between categorization and recognition. A model of interactions between the two tasks is proposed that postulates two separate but interacting types of knowledge.     

Perceived Coparenting Support and Later Relationship Status among Cohabiting Parents

Abstract

To help with the fragile nature of cohabiting parents' relationship, more understanding about their interpersonal experiences is needed to identify factors that matters for their relationship stability. We examined how cohabiting parents' perceived coparenting support from their partner was associated with their later relationship status (married/cohabiting/not together). Further, we examined the possible moderating effect of perceived coparenting support on the association between marriage plans and later relationship status. Results suggested that the associations between fathers' plans and couples' marriage entrance as well as continued cohabitation were dependent upon fathers' perceived coparenting support from mothers. Clinical and research implications are discussed.     

Blue Monday Is Real for Suicide: A Case–Control Study of 188,601 Suicides

Many studies have reported that suicides tend to occur on Mondays. However, owing to a lack of controls, conclusive findings on the potential effects of a day of the week on suicides have been lacking. We analyzed public data for causes of death from 1997 to 2015 in the Republic of Korea. Accidental death was used as a control group. The probability of suicide on each day of the week according to age group was calculated. A total of 377,204 deaths (188,601 suicides and 188,603 accidental deaths) were used. The frequency of suicide was highest on Monday and decreased throughout the week until Saturday. Accidental death was highest on Saturday and showed no variations according to weekday. For people in their teens and 20s, the probabilities of suicide on Monday were 9% and 10% higher, respectively, than those on Sunday. As age increased, the differences in suicide probability according to the day of the week were attenuated. The so‐called Blue Monday effect is real, particularly for people in their teens and 20s. Suicide prevention strategies that aim to attenuate the burden and stress of Mondays should be planned.
