We investigated correlates of gender segregation among adolescent (15–17 yrs) boys (N?=?60) and girls (N?=?85) from the Mid-Atlantic United States. Seventy-two percent of peers nominated for “hanging out” were the same gender as the adolescent. Girls’ gender segregation was correlated with gender reference-group identity and believing girls are more responsive communicative partners than boys. Girls were more likely to endorse feminine, expressive traits, a cooperative activity orientation, and to believe in the greater communicative responsiveness of same- vs. other-gender peers. Boys and girls were equally likely to endorse masculine, instrumental traits, competitive activity orientations, and to identify same-gender others as a reference group. We consider implications of the developmental persistence of gender segregation for gender-typing.  相似文献

Simple heuristics of the type introduced by Gigerenzer, Todd, and The ABC Research Group ( 1999 ) embody principles for information search, stop and decision making. These heuristics suggest that such processes are simple. In an analysis of general practitioners' (GPs) information search and decision‐making behaviour when prescribing a lipid lowering drug, we examined whether information search was simple, and whether a heuristic that predicts a simple decision‐making process was also accurate at describing information search. We found that GPs' information search behaviour was simple in that it demonstrated characteristics of the matching heuristic (e.g. stopping rule). In addition, although the matching heuristic which correctly predicted on average 75% of GPs' decisions used significantly fewer cues on average than the GPs did in the information search task, it was reasonably accurate in describing order of information search. These findings have implications for the validity of simple heuristics describing both information search and decision making. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

How does expertise in the analysis of particular images influence the effects of visual saliency upon attention? Expert analysts of aerial photographs and untrained viewers undertook change‐detection and location memory tasks using aerial photographs with eye movements recorded throughout. Experts were more accurate in both tasks. Significant differences were also seen in the scanpaths: Untrained viewers fixated preferentially upon salient features throughout stimulus presentation whereas experts did not. However, both groups showed a strong influence of saliency in change detection and memory tasks. We interpret this apparent contradiction by: (i) assuming that the use of saliency in visual search is discretionary, and experts can use semantic information to prioritise where to fixate next; whereas, (ii) in tasks requiring spatial memory, analysis of visual saliency delivers easily acquired landmarks to reference the location of items in an image; a previously overlooked function used by expert and untrained viewers alike.

The “action effect,” according to which actions produce more regret than failures to act, has been shown to disappear in between-subject designs. This phenomenon is replicated in a first study. It is then argued that this disappearance is due to the inability of regret scales to capture differences in perceived regret when used in between-subject designs, a difficulty that is highlighted by a second study. A new method, the common reference method, is proposed in order to overcome this problem. This method is demonstrated in a third and fourth study, and its boundary conditions are discussed, together with its possible extensions.  相似文献

Three studies of human nonmonotonic reasoning are described. The results show that people find such reasoning quite difficult, although being given problems with known subclass-superclass relationships is helpful. The results also show that recognizing differences in the logical strengths of arguments is important for the nonmonotonic problems studied. For some of these problems, specificity – which is traditionally considered paramount in drawing appropriate conclusions – was irrelevant and so should have lead to a “can’t tell” response; however, people could give rational conclusions based on differences in the logical consequences of arguments. The same strategy also works for problems where specificity is relevant, suggesting that in fact specificity is not paramount. Finally, results showed that subjects’ success at responding appropriately to nonmonotonic problems involving conflict relies heavily on the ability to appreciate differences in the logical strength of simple, non-conflicting, statements.  相似文献

We review the research on intimate partner abuse and, in particular, the articles in this issue, from within a feminist and postmodern framework. Research on women's use of violence is reviewed in terms of how researchers have constructed and measured violence and have conceptualized intimate partner violence (IPV) and gender. What and how we measure determines what we find ( McHugh & Cosgrove, 2005 ). We call for new conceptualizations of intimate violence and for more complex constructions of gender. We offer a postmodern perspective on gender and IPV arguing that interpersonal violence always involves gender, that approach and method influence results, and that men and women use violence in both similar and different ways.  相似文献

An essential feature of psychodynamic counselling is a secure frame for the work that holds boundaries as sacrosanct, both to ensure ethical practice and to provide a vehicle through which unconscious processes can be recognized and understood. Conscious or unconscious attacks on the frame are inevitable in any therapeutic relationship, and provide an opportunity for exploration and insight. However such incidents also have an impact on the therapist who must decide how to respond. In order to understand more about the therapist process when there is an attack on the frame, an investigation was carried out into ways in which psychodynamic counsellors manage the difficulties and dilemmas that arise as they try to hold a secure therapeutic frame. Ten counsellors were interviewed using a semi‐ structured interview format during which they were asked about an instance when the frame was challenged and the process by which it was resolved. The resulting dilemmas were categorized using grounded theory. Three categories of dilemmas emerged a) prior to making a decision about how to deal with it, b) after making a decision, and c), as a result of the outcome of the action taken. The nature of the dilemmas and the process of resolving them are reported and discussed.  相似文献

Temporal logics of knowledge are useful for reasoning about situations where the knowledge of an agent or component is important, and where change in this knowledge may occur over time. Here we use temporal logics of knowledge to reason about the game Cluedo. We show how to specify Cluedo using temporal logics of knowledge and prove statements about the knowledge of the players using a clausal resolution calculus for this logic. We discuss the advantages and disadvantages of using this logic to specify and verify the game Cluedo and describe related implementations.  相似文献

The first 1,000 days of life are a critical window of vulnerability to exposure to socioeconomic and health challenges (i.e. poverty/undernutrition). The Brain Imaging for Global Health (BRIGHT) project has been established to deliver longitudinal measures of brain development from 0 to 24 months in UK and Gambian infants and to assess the impact of early adversity. Here results from the Habituation‐Novelty Detection (HaND) functional near‐infrared spectroscopy (fNIRS) task at 5 and 8 months are presented (N = 62 UK; N = 115 Gambia). In the UK cohort distinct patterns of habituation and recovery of response to novelty are seen, becoming more robust from 5 to 8 months of age. In The Gambia, an attenuated habituation response is evident: a larger number of trials are required before the response sufficiently suppresses relative to the response during the first presented trials. Furthermore, recovery of response to novelty is not evident at 5 or 8 months of age. As this longitudinal study continues in The Gambia, the parallel collection of socioeconomic, caregiving, health and nutrition data will allow us to stratify how individual trajectories of habituation and recovery of response to novelty associate with different risk factors and adaptive mechanisms in greater depth. Given the increasing interest in the use of neuroimaging methods within global neurocognitive developmental studies, this study provides a novel cross‐culturally appropriate paradigm for the study of brain responses associated with attention and learning mechanisms across early development.  相似文献
