Altering comprehension: The effect of biasing titles on text comprehension

Titles can alter the comprehension of a text by affecting the selection of information from a text and the organization of this information in memory. Text comprehension is assumed to involve an organizational process that results in the formation of a text base, an ordered list of semantic units—propositions. The text base can be used as a retrieval scheme to reconstruct the text. Procedures for assigning propositions as more relevant to some themes as compared to other themes are developed and applied to texts. Texts with biasing titles were used in an experiment to demonstrate that immediate free recall is biased toward the theme emphasized in the title. The comprehension process which is guided by the text’s thematical information is described.     

Effects of cage mesh on pointing: hand shapes in chimpanzees (<Emphasis Type="Italic">Pan troglodytes</Emphasis>)

It has been speculated that cage mesh exerts a shaping influence on reaching behavior by captive apes, which is then misconstrued as pointing by human observers. Although this notion is clearly falsified by the pointing of captive language-trained apes—who point in the absence of intervening cage mesh—nevertheless, the degree to which cage mesh might influence pointing hand shapes by captive great apes in other housing environments remains relatively unexplored. We examined 259 pointing gestures displayed in archival footage from over 18 h of observation by three nonlanguage-trained chimpanzees housed at a biomedical research center. We coded points in relation to how close to the boundaries of the diamond-shaped cage mesh their points were displayed. We found that points with the whole hand were significantly more likely to be displayed away from the mesh boundaries, relative to points with the index finger or other single-digit points. However, points of each hand shape were displayed at each location, demonstrating that these physical parameters do not fully account for the number of fingers extended while pointing by chimpanzees.     

Remembering talk: Individual and gender differences in reported speech

This study examined individual and group differences in the nature and frequency of reports of past speech in the autobiographical memories of young adults. A sample of 108 participants (60 females, 48 males) responded in writing to six memory prompts. They also completed the Five Factor Inventory (Costa & McCrae, 1992) and the Personal Attributes Questionnaire (Spence & Helmreich, 1978). The frequency with which participants used reported speech was correlated with agreeableness, openness, and expressivity; however, regression analyses indicated that narrators’ gender alone was the best predictor. Females used more reported speech than did males. The findings suggest that recollections of past speech are an under-appreciated yet important component of autobiographical memory.     

The prevalence,risk factors and outcomes of workplace bullying among junior doctors: a systematic review

ABSTRACT

Junior doctors’ exposure to bullying may impact their training and compromise quality healthcare, yet little is known in relation to its predictors and effects. The aim of this paper is to assess the prevalence, factors and outcomes of workplace bullying among junior doctors. Literature search was performed to identify all primary studies examining workplace bullying among junior doctors using the following electronic databases: Medline, Scopus, Web of Science, PsycINFO and Cochrane Library. A total of 18 articles were included, reporting on a total of 9,597 junior doctors. The quality of evidence can be rated as moderate according to the Newcastle Ottawa Scale. From the review, a wide range (30–95%) of bullying prevalence, significant differences in bullying rates according to gender, age, height, ethnicity and subspecialty, and significant associations between bullying and mental strain, job dissatisfaction, burnout, and increased accidents at work were observed. Concurrently, heterogeneity in the terms and methodologies used to examine workplace bullying as well as definitional issues in relation to the persistency of negative interactions were noted. Evidence suggests that workplace bullying is a serious occupational hazard for junior doctors, and more research is warranted to better understand this phenomenon and address its definitional and methodological issues.     

A contingency model of conflict and team effectiveness

The authors develop and test theoretical extensions of the relationships of task conflict, relationship conflict, and 2 dimensions of team effectiveness (performance and team-member satisfaction) among 2 samples of work teams in Taiwan and Indonesia. Findings show that relationship conflict moderates the task conflict-team performance relationship. Specifically, the relationship is curvilinear in the shape of an inverted U when relationship conflict is low, but the relationship is linear and negative when relationship conflict is high. The results for team-member satisfaction are more equivocal, but the findings provide some evidence that relationship conflict exacerbates the negative relationship between task conflict and team-member satisfaction.     

Placement or placebo: Does additional information change special education placement decisions

The effect of relevant information on the decision to place pupils in special education services was investigated. Ten placement decision committees were given information on 12 referred pupils, half of which included social history information on the pupil and orthogonally half of which were recommended for special education services by an outside psychologist. Analysis of the committee's 120 decisions revealed no significant relationship either between the psychologist's recommendation and the committee's decisions or between the presence of social histories and the committee's decisions. The results are discussed in terms of information advocacy within the committees.     

Being Brave, Being Nice: Themes of Agency and Communion in Children's Narratives

Although much is known about the presence of themes of agency and communion in adults' autobiographical stories, little is known about the presence of these themes in children's autobiographical stories. In this paper we examine the extent to which children describe themselves and others as agentic and communal beings in ordinary conversational narratives. Subjects were 96 rural, working-class children between the ages of 4 and 9 years. Personal narratives were elicited in the course of informal conversations with an adult experimenter. Narratives were analyzed for the presence of storyworld participants, and for the presence of themes of agency and communion. For both genders, themes of agency were more common than were themes of communion. Girls, however, were more likely to describe themes of communion than were boys, and were more likely to include family members in their narratives than were boys. Finally, correlations between themes of agency and communion were generally low. The findings extend the age to which the concepts of agency and communion can be productively applied to personal narratives. Implications for future theoretical and empirical work are also discussed.     

Ecstasy and agony: activation of the human amygdala in positive and negative emotion

Considerable evidence indicates that the amygdala plays a critical role in negative, aversive human emotions. Although researchers have speculated that the amygdala plays a role in positive emotion, little relevant evidence exists. We examined the neural correlates of positive and negative emotion using positron emission tomography (PET), focusing on the amygdala. Participants viewed positive and negative photographs, as well as interesting and uninteresting neutral photographs, during PET scanning. The left amygdala and ventromedial prefrontal cortex were activated during positive emotion, and bilateral amygdala activation occurred during negative emotion. High-interest, unusual photographs also elicited left-amygdala activation, a finding consistent with suggestions that the amygdala is involved in vigilance reactions to associatively ambiguous stimuli. The current results constitute the first neuroimaging evidence for a role of the amygdala in positive emotional reactions elicited by visual stimuli. Although the amygdala appears to play a more extensive role in negative emotion, it is involved in positive emotion as well.     

Remembering and repeating in multiple personality

This paper is a case-history of a student in his early twenties tortured by different personalities of different ages and sexes vying for control of his body. Guilt over an incestuous relationship with his mother is uncovered and understood in the context of his whole life. Confusion between memories of fantasies, memories of sleep dreams, memories of daydreams, and memories of actual memories are described, the elucidation of which lead to clearer thinking and memory, and more tolerance for the previously distorted affectladen situations of his past. Thus his belief that he was experimented on in an alien spaceship becomes the memory of an operating-room diagnostic experience.

A hypothesis is put forward that the separate personalities in the multiple personality are not simply the products of ego splits, but are at the instant they are formed a ‘doubling’ of the personality that is being copied. Immediately thereafter, splitting mechanisms create differences between the two separate personalities, using projective and introjective mechanisms. Integration of the various personalities, the ultimate goal in treatment, is made difficult by the patient's fear of loss of self through fragmentation, when the self is felt to be in danger of being intruded upon.
