Ethical Research in Delirium: Arguments for Including Decisionally Incapacitated Subjects

Here we describe how more important findings were obtained in a delirium study by using an informal assessment of mental capacity, and, in those who lacked capacity, obtaining consent later when or if capacity returned or a proxy was found. From a total of 233 patients 23 patients lacked capacity as judged by our informal capacity judgment and 210 did not. Of those who lacked capacity, 13 agreed to enter in the study. Six of them regained capacity later. When these 13 participants were excluded from analysis, significant findings were no longer evident. These results show that by the inclusion of subjects who lacked capacity the results of analyses of the condition from whish they suffer are altered. We suggest that this approach to the study of delirium is more ethical than the usual system of strict exclusion of people who lack capacity to give consent and for whom assent is not available.     

Gavagai Is as Gavagai Does: Learning Nouns and Verbs From Cross‐Situational Statistics

Learning to map words onto their referents is difficult, because there are multiple possibilities for forming these mappings. Cross‐situational learning studies have shown that word‐object mappings can be learned across multiple situations, as can verbs when presented in a syntactic context. However, these previous studies have presented either nouns or verbs in ambiguous contexts and thus bypass much of the complexity of multiple grammatical categories in speech. We show that noun word learning in adults is robust when objects are moving, and that verbs can also be learned from similar scenes without additional syntactic information. Furthermore, we show that both nouns and verbs can be acquired simultaneously, thus resolving category‐level as well as individual word‐level ambiguity. However, nouns were learned more quickly than verbs, and we discuss this in light of previous studies investigating the noun advantage in word learning.     

Correlates of suicidality among patients with psychotic depression

The independent association of age and other factors with suicidality in patients with major depression with psychotic features was examined. Of the 183 study participants, 21% had a suicide attempt during the current episode. Male gender, Hispanic background, past suicide attempt, higher depression scores, and higher cognitive scores were each independently associated with greater intensity of current suicidality. Older age was independently associated with a lower risk of a lifetime suicide attempt. These findings reinforce the evidence that patients with psychotic depression are at high risk for suicide and underscore the importance of examining correlates of suicidality specific to patients with psychotic depression.     

Weight and muscularity concerns as longitudinal predictors of body image among early adolescent boys: a test of the dual pathways model

The purpose of this research was to examine the longitudinal contributions of weight loss and muscularity concerns as dual pathways to body image dissatisfaction among early adolescent boys. Study 1 included 67 boys who reported on weight loss concerns, internalized muscular ideal, BMI, and body dissatisfaction during 7th grade and 1 year later. In Study 2, 87 7th and 8th grade boys were assessed in the fall and spring of a school year. The results confirmed that although both weight and muscularity concerns were related to body dissatisfaction, concern with weight loss more strongly detracted from a positive body image than did muscularity concern. The findings are discussed in terms of potential developmental variations in the relative contribution of weight and muscularity to body dissatisfaction among adolescent boys.     

The Effects of Programme Context on Memory for Humorous Television Commercials

This study investigated the effects of programme context on memory for humorous television advertisements in South Korean participants. Humorous and nonhumorous Korean advertisements were embedded within two programme contexts: humorous and nonhumorous. When the programme ratings of humour, enjoyment and involvement were higher, unaided recall was poorer. In addition, unaided recall of the advertisements was better when they were embedded within a nonhumorous programme. However, there was no significant programme‐advertisement interaction effect. Overall, both free and cued recall were higher for humorous advertisements than for the nonhumorous advertisements. The findings are discussed in terms of cultural differences and changes in television programmes and advertising over time.Copyright © 2017 John Wiley & Sons, Ltd.
