Tower of Hanoi performance of retarded young adults and nonretarded children as a function of solution length and goal state

Three experiments were conducted with the Tower of Hanoi task to assess problem solving ability in 6-, 7-, 8-, and 10-year-old nonretarded children and mentally retarded young adults of varying maturational ages. In Experiment 1 we gradually reduced the number of moves required for solution until subjects could solve the 3-disk tower-ending problem. Although all groups experienced difficulty with the standard 7-move problem, all but the trainable retarded group readily solved the 6-move problem. The trainable group did not reach a comparable level of success until the 4-move problem. On the 7-move problem the retarded groups performed at the level of nonretarded groups that were maturationally $\text{1}\text{1}\text{2}$ to 3 years younger. An analysis of first moves indicated that subject groups differed in the strategies they used to solve the problems. In Experiment 2, practice effects were ruled out as a source of the superior performance on the 6- than on the 7-move problem. In Experiment 3, 7- and 10-year-old nonretarded children and mentally retarded young adults did not differ on 5-move problems in which configuration of the goal states was varied. A comparison of all 5-move problems judged to have the same depth of search requirements indicated that the tower-ending problems were significantly easier to solve than the partial-tower-ending problems, which in turn were easier than the flat-ending problems. A limited depth of search capacity sets boundaries on the use of sophisticated strategies and, to a large extent, accounts for the retarded groups' maturational lag.     

Information Seeking Within Organizations

In this article, both the literature on employee feedback‐seeking behavior and the literature on information seeking by organizational newcomers are reviewed. This review highlights the various motives that affect the decision of whether or not to seek information, shows how the strength of those motives is affected by both characteristics of the individual and characteristics of the organizational context, and reviews evidence that information seeking has beneficial outcomes. The author then offers an integrated model of antecedents, dynamics, forms, and outcomes of employee information seeking and concludes with suggestions for how future research can extend current understanding of employee information seeking.     

Testing a Moderated Mediation Model of Objectification Theory among Black Women in the United States: The Role of Protective Factors

Recent studies find that Black women experience rates of eating pathology and body dissatisfaction comparable to those of White women. Abundant research suggests that objectification theory could help explain the development and maintenance of eating disorder (ED) symptoms among diverse women. However, research on the applicability of objectification theory to ED symptoms in Black women is equivocal. Specifically, some have suggested that body surveillance might operate differently for Black women. Thus, the current study examined ethnic-racial identity (ERI) commitment and body appreciation as moderators of the mediated associations among body surveillance, body shame, and ED symptoms. Black women (n?=?175) in the United States completed measures of body image, ERI commitment, and ED symptoms. Consistent with objectification theory, body shame mediated the association between body surveillance and ED symptoms. Contrary to our hypothesis, ERI commitment did not moderate the link between body surveillance and body shame. However, body appreciation was a significant moderator, such that the strength of the relation between body surveillance and ED symptoms via body shame was weakened at high levels of body appreciation. Future work should consider interventions that foster body appreciation in Black women.

     

Affect and emotions in placebo and nocebo effects: What do we know so far?

Once considered nuisance variance in clinical trials, placebo effects and nocebo effects are now widely recognized as important and mutable psychobiological contributors to mental and physical health. Psychological theory explaining these effects emphasizes associative learning and conscious expectations. It has long been suggested, however, that affective states such as moods, emotions, and distress could play a significant role. In this paper, we draw together and review the empirical data linking affective states to placebo and nocebo effects. To organize this disparate literature, three questions are addressed: (1) Does pre‐existing state and trait affect modulate placebo and nocebo effects? (2) Does administering placebo and nocebo treatments change affective states, and if so, does the resulting affect causally influence placebo and nocebo effects? Finally, (3) Can placebo treatments be successfully employed as a regulation strategy to modulate different affective states? In reviewing the evidence in relation to these three questions, it is clear that affect does play a key role in placebo and nocebo effects in many circumstances, and further, there may be a reciprocal dynamic at play between a treatment event, affect, and placebo/nocebo effects. The paper concludes by discussing implications for theory and intervention and recommends future research priorities.     

Psychiatric diagnoses in infancy: A comparison

This study investigated the specificity of diagnostic classification in two standardized systems: DSM-IV and Diagnostic Classification: Zero to Three. A sample of 82 infants aged 1–24 months suffering from various psychogenic and functional pediatric symptoms was diagnosed applying both systems. For DC: 0–3 (the Diagnostic Classification on Mental Health and Developmental Disorders of Infancy and Early Childhood), this study presents results with respect to the specificity of symptom patterns. Twelve out of 27 symptoms, specific for disorders in early infancy, showed high specificity and were significantly discriminative for the diagnostic entities. These symptoms were differentiated for frequency and severity of occurrence for each diagnosis. In the sample, DSM-IV and DC: 0–3 diagnoses were compared. Additionally, 13 items of biographical-biological data were collected (e.g., low SES combined with very young or older mothers resulted in an increased risk for psychiatric disorders in early infancy). The data provide support for the idea that the use of DC: 0–3 in early infancy may be helpful in relation to daily routines and research by increasing the range of clearly defined diagnostic entities.     

‘Personality in Its Natural Habitat’ Revisited: A Pooled,Multi-sample Examination of the Relationships Between the Big Five Personality Traits and Daily Behaviour and Language Use

Past research using the Electronically Activated Recorder (EAR), an observational ambulatory assessment method for the real-world measurement of daily behaviour, has identified several behavioural manifestations of the Big Five domains in a small college sample (N = 96). With the use of a larger and more diverse sample of pooled data from N = 462 participants from a total of four community samples who wore the EAR from 2 to 6 days, the primary purpose of the present study was to obtain more precise and generalizable effect estimates of the Big Five–behaviour relationships and to re-examine the degree to which these relationships are gender specific. In an extension of the original article, the secondary purpose of the present study was to examine if the Big Five–behaviour relationships differed across two facets of each Big Five domain. Overall, while several of the behavioural manifestations of the Big Five were generally consistent with the trait definitions (replicating some findings from the original article), we found little evidence of gender differences (not replicating a basic finding from the original article). Unique to the present study, the Big Five–behaviour relationships were not always comparable across the two facets of each Big Five domain. © 2020 European Association of Personality Psychology     

Stigma towards psychosis: Cross‐cultural differences in prejudice,stereotypes, and discrimination in White British and South Asians

Public stigma towards people with mental health problems has been demonstrated in Western societies. Little is known about non‐Western cultures and whether cultures differ in their perceptions of people with mental health problems. Aim of this study was to examine cultural differences in prejudice, stereotypes, and discrimination towards people with psychosis. Participants were from White British and South Asian backgrounds (N = 128, aged 16–20 years) recruited from two schools and colleges in the United Kingdom. They completed a cross‐sectional survey on affective, cognitive, and behavioural dimensions of stigma. Results revealed significant cultural differences on all three stigma dimensions. South Asians attributed higher anger (prejudice) and dangerousness (stereotypes) to people with psychosis than White British. They also reported lower willingness to help, greater avoidance, and higher endorsement of segregation (discrimination). The effects of ethnic group on helping intentions, avoidance, and segregation endorsement were mediated by anger and by dangerousness. Understanding cultural differences in stigma towards psychosis will be important for designing stigma interventions as well as treatments for people with different cultural backgrounds.
