Linking relations described in text with relations in visualizations is often difficult. We used eye tracking to measure the optimal way to extract such relations in graphs, college students, and young children (6- and 8-year-olds). Participants compared relational statements (“Are there more blueberries than oranges?”) with simple graphs, and two systematic patterns emerged: eye movements that followed the verbal order of the question (inspecting the “blueberry” value first) versus those that followed a left-first bias (regardless of the left value’s identity). Question-order patterns led substantially to faster responses and increased in prevalence with age, whereas the left-first pattern led to far slower responses and was the dominant strategy for younger children. We argue that the optimal way to verify a verbally expressed relation’s consistency with visualization is for the eyes to mimic the verbal ordering but that this strategy requires executive control and coordination with language. 相似文献

Learning abilities are exhibited by many animals, including insects. However, sedentary species are typically believed to have low capacities and requirements for learning. Despite this view, recent studies show that even such inconspicuous organisms as larval antlions, which employ an ambush predation strategy, are capable of learning, although their learning abilities are rather simple, i.e., limited to the association of vibrational cues with the arrival of prey. This study demonstrates, for the first time, that antlion larvae can use vibrational cues for complex modifications of their foraging strategies. Specifically, antlion larvae rapidly learn to differentiate between the vibrational cues associated with prey of different sizes, and they save resources by ignoring smaller prey in favour of larger, more energetically profitable prey. Moreover, antlion larvae can learn to associate vibrational cues with the loss of their prey, and they respond by burying their victims under the sand more often and more rapidly than do individuals with no opportunities to form such associations. These findings provide not only new insights into the cognitive abilities of animals but also support for the optimal foraging strategy concept, suggesting the importance of maximizing fitness output by balancing the costs and benefits of alternative foraging strategies. 相似文献

Not as Different as We Want to Be: Attitudinally Consistent Trait Desirability Leads to Exaggerated Associations Between Personality and Sociopolitical Attitudes 下载免费PDF全文
Research connecting sociopolitical attitudes to personality typically relies exclusively on self‐report measures of personality. A recently discovered mechanism of bias in self‐reports highlights a particular challenge for this approach. Specifically, individuals tend to report exaggerated levels of a trait to the extent that they view that trait as desirable. In a community sample of 443 participants, differences in sociopolitical attitudes were associated with differences in the extent to which individuals provided biased self‐reports for a given trait (relative to trait levels indicated by peer‐report or an objective measure) as well as differences in views of the desirability of that trait. Further, the tendency to misrepresent traits in a manner consistent with one's sociopolitical attitudes was mediated by differences in views of trait desirability. Thus, although meaningful personality differences exist among those with differing sociopolitical attitudes, those differences may not be as large as people with opposing sociopolitical attitudes might like them to be. 相似文献

Families of unarmed civilians who live in warzones at political conflict areas are at risk of exposure to traumatic ongoing terrorism (OGT). This paper focuses on families living at the political conflict area by the border of the Gaza Strip at southwestern Israel, who have experienced OGT of missile fire for a decade and a half. Case examples illustrate the nuances and details of traumatic events, such as massive bombing, life threatening situations, evacuation, threat to and loss of life of family members and close friends, and their implications on the family system along life span. Members of these families are at risk of posttraumatic reactions and maladaptive system functioning in relation to the traumatic context of their specific life cycle stage. However, some families have shown potential for developing resilience, related to three main dimensions: belief system, organizational patterns, and communication channels. The objective of the present paper is to shed light, by evidence of families exposed to OGT, on risk and resilience factors affecting a family’s ability to overcome trauma throughout the lifecycle. 相似文献

Additional information contained in incorrect responses calls for a multicategorical rather than a binary analysis of multiple choice data. A nonparametric divided-by-total model for joint maximum likelihood estimation of probability-of-choice functions (for particular responses) and of latent ability is proposed. The model approximates probability functions by rational splines. Some illustrative examples of real test data analysis and the results of a Monte Carlo study are presented.The research in this paper was supported by the National Sciences and Engineering Research Council of Canada Grants OGP0105521 and APA 320 awarded to the first and the second author, respectively. The authors are indebted to R. Melzack and A. Baker for making available the data analyzed in this paper. We would also like to thank J. McKenna and B. Cont for their assistance in editing this paper. 相似文献

This paper describes a phenomenon of using a threat to divorce by families in extreme distress (FED) as a way of maintaining family homeostasis; that is, using a threat to divorce but never really implementing it. By relating to processes, such as social exchange and attachment, that often take place in the decision-making of divorce, we try to understand why those families choose to use the threat, thereby explaining this phenomenon. Using components of defining family boundaries, excitement and power struggle, we are thus able to better understand the existence of the phenomenon among FED. 相似文献

The degree of cohesion and support within families has often been considered a predictor of students' effort-investment and success in school. The objectives of this study are to examine the roles of personal factors (i.e., sense of coherence and hopeful thinking) as well as interpersonal factors (i.e., loneliness) in mediating the relationship between family cohesion and effort. The sample consists of 1719 elementary school children (781 boys and 938 girls) from the fifth and six grades (mean age = 10.25, SD = 0.70) of 29 elementary schools in central Israel. Students answered study questionnaires in the middle of their academic year. Analyses utilizing hierarchical multiple regression and Hayes' bootstrapping approach (PROCESS; Preacher & Hayes, 2008) were used. The results support the distinctive contribution of family cohesion and the mediating roles of sense of coherence and hope (as protective factors) as well as loneliness (as a risk factor) in predicting students' school effort. This study has important educational implications, emphasizing the value of promoting hopeful thinking and coping with loneliness in helping students to thrive in their studies. 相似文献

Most papers using experimental data find that a significant number of agents are not utility function maximizers. Using three experimental datasets, we provide empirical evidence that these violations of utility function maximizing behavior are simply generated by a violation of the preference transitivity axiom. Moreover, we find that 97% of agents’ behavior is consistent with maximization of a generalized utility function called a variable intervals function (which corresponds to a numerical representation of complete-acyclic preferences). 相似文献

Adult attention deficit and hyperactivity disorder (ADHD) manifests itself through a variety of symptoms, some of which affect not only occupational and recreational activities but also intimate relationships. Previous findings have focused on the effects of adult ADHD on intimacy and relationships from the ADHD diagnosed person’s point of view. However, spouses of people with ADHD are a neglected population with regard to the effects that ADHD has on their romantic relationships. Our aim was to assess the effects of being married to a spouse with ADHD on marital relationships, and the moderating role of intimacy. We compared healthy spouses of people with ADHD to healthy spouses of healthy adults (M?=?38.23, SD?=?4.78) in their degree of self-reported intimacy and marital satisfaction. Our findings indicate that spouses of individuals with ADHD report significantly lower intimacy and lower marital satisfaction compared to spouses of individuals without ADHD. Moreover, our findings indicate that spousal reports about their degree of intimacy mediate the relationships between their spouses’ ADHD and their marital satisfaction. Results are discussed in relation to the broad implications that adult ADHD has for romantic intimacy. Our research addresses healthy partners married to a spouse with ADHD, suggesting that living with a partner with ADHD behaviors is challenging. ADHD symptoms negatively affect various qualities in the person experiencing them, but of equal importance is the damage occurring to his or her spouse. Implications for future research and recommendations for clinical work are suggested. 相似文献
