Sexual and aggressive play fighting of sibling Richardson’s ground squirrels

Play fighting in many species of squirrels can involve sexual play and aggressive play, both of which can lead to wrestling which appears superficially similar. Such convergence can make scoring of the relative frequencies of these two types of play difficult and can lead to the mistaken conclusion that they grade into one another. In this study, both staged laboratory encounters between sibling pairs and spontaneous encounters between siblings in free‐living litters of Richardson’s ground squirrels (Spermophilus richardsonii) were videotaped. Frame‐by‐frame analyses using the Eshkol‐Wachman Movement Notation were employed to record the correlated movements of attack and defense by the partners and to reveal the body areas targeted during each play bout. Whereas sexual play was organized around access to the rump, aggressive play was organized around the shoulders. Although in most cases the defender’s tactics blocked access to the respective target, when contact did occur, it involved mounting in sexual play and nosing or biting in aggressive play. Eighty‐six percent of play fights could be unambiguously categorized as either sexual or aggressive play. Of these, the majority (?80%) involved sexual play. The sex of the participants did not affect the frequency of aggressive play, but in sexual play, males initiated more attacks than females. Once initiated, each form of play fighting remained distinct—if a bout began as sexual play, it would end as sexual play. Furthermore, a counterattack following sexual play was significantly more likely to be sexual than aggressive, and vice versa for counterattacks following aggressive play. Therefore, all the evidence suggested that the two forms of play fighting were not intermixed in Richardson’s ground squirrels. Aggr. Behav. 27:323–337, 2001. © 2001 Wiley‐Liss, Inc.     

Associations Among Aspects of Interpersonal Power and Relationship Functioning in Adolescent Romantic Couples

This study used a multidimensional assessment of interpersonal power to examine associations between indices of relationship power and relationship functioning in 92 adolescent romantic couples recruited from rural communities in the Rocky Mountain region of the USA. Significant differences emerged between girlfriends and boyfriends in their reports of decision making authority, perceptions of humiliating behaviors by the partner, and ratings of themselves giving-in to their partners in a videotaped interaction task. In addition, indices of interpersonal power were associated with dating aggression and relationship satisfaction for both girlfriends and boyfriends, although gender differences emerged in the patterns of association between power and outcomes. Results are discussed in light of current developmental, feminist, and social psychological theories of interpersonal power in romantic relationships.     

Effects of Problem Solving after Worked Example Study on Primary School Children's Monitoring Accuracy

Research on expository text has shown that the accuracy of students' judgments of learning (JOLs) can be improved by instructional interventions that allow students to test their knowledge of the text. The present study extends this research, investigating whether allowing students to test the knowledge they acquired from studying a worked example by means of solving an identical problem, either immediately or delayed, would enhance JOL accuracy. Fifth grade children (i) gave an immediate JOL, (ii) a delayed JOL, (iii) solved a problem immediately and then gave a JOL, (iv) solved a problem immediately and gave a delayed JOL, or (v) solved a problem at a delay and then gave a JOL. Results show that problem solving after example study improved children's JOL accuracy (i.e., overestimation decreased). However, no differences in the accuracy of restudy indications were found. Results are discussed in relation to cue utilization when making JOLs. Copyright © 2014 John Wiley & Sons, Ltd.     

Measuring Epistemic Curiosity in Young Children

Epistemic curiosity (EC) is the desire to obtain new knowledge capable of either producing positive experiences of intellectual interest (I‐type) or of reducing undesirable conditions of informational deprivation (D‐type). Although researchers acknowledge that there are individual differences in young children's epistemic curiosity, there are no existing measures to assess the I‐ and D‐type constructs of EC in early childhood. The aim of this study was to develop and validate parent‐report scales that reliably assessed early expressions of I‐ and D‐ type EC in young children. To develop the I/D‐Young Children (I/D‐YC) scales, 16 potential items were administered to 316 parents of children aged 3 to 8. These items were adaptations of an existing adult self‐report measure of EC as well as newly developed items. Confirmatory factor analyses demonstrated that a 10‐item 2‐factor (5 I‐type, 5 D‐type) model had the best fit. Construct validity analyses and psychometric data indicated that our newly developed I/D‐YC scales are valid and reliable measures of individual differences in early expressions of I‐ and D‐type EC.

The effect of layout and pacing on learning from diagrams with unnecessary text

Although the presentation of extraneous (i.e., irrelevant or unnecessary) information hinders learning, it is unclear whether and how layout and pacing influence this effect. In two experiments, participants learned how the heart functions using four different layouts: a diagram presented without unnecessary text (diagram only), with unnecessary text separated from the diagram (separated) or integrated into the diagram (integrated), or with separated unnecessary text and the instruction to integrate (integration instruction). In Experiment 1, study time was self‐paced for half of the participants and system paced for the other half. There were no effects of layout and of pacing on learning, although system pacing was more effortful than self‐pacing. In Experiment 2, which was system paced and employed eye tracking, the integrated condition showed worse learning outcomes than the separated condition. Moreover, in the integrated condition, participants made more integration attempts between the unnecessary text and the diagram than in the separated condition.     

Inferring task performance and confidence from displays of eye movements

Eye movements reveal what is at the center of people's attention, which is assumed to coincide with what they are thinking about. Eye-movement displays (visualizations of a person's fixations superimposed onto the stimulus, for example, as dots or circles) might provide useful information for diagnosing that person's performance. However, making inferences about a person's task performance based on eye-movement displays requires substantial interpretation. Using graph-comprehension tasks, we investigated to what extent observers (N = 46) could make accurate inferences about a performer's multiple-choice task performance (i.e., chosen answer), confidence, and competence from displays of that person's eye movements. Observers' accuracy when judging which answer the performer chose was above chance level and was higher for displays reflecting confident performance. Observers were also able to infer performers' confidence from the eye-movement displays; moreover, their own task performance and perceived similarity with the performer affected their judgments of the other's competence.     

Illness Perception and Well-Being Among Persons with Multiple Sclerosis and Their Caregivers

This study jointly examined illness beliefs held by persons with multiple sclerosis (PwMS) and caregivers in relation to well-being. A group of 68 PwMS and their caregivers completed the Revised Illness Perception Questionnaire, Psychological Well-being Scales, Satisfaction with Life Scale and Positive Affect and Negative Affect Schedule. Findings revealed that PwMS’ well-being was primarily predicted by their own illness beliefs, and that also caregivers’ well-being was primarily predicted by their own beliefs. Across the two groups, well-being was positively associated with their belief that they understood the disease, and inversely associated with their representations of negative emotions. In addition, among PwMS, well-being was inversely associated with the number of symptoms they specifically attributed to their illness, while among caregivers, well-being was positively associated with beliefs that treatment could control the disease. Based on the study findings, psychoeducational and cognitive-behavioral strategies are suggested to promote well-being among PwMS and caregivers.     

Does Career Success Make You Happy? The Mediating Role of Multiple Subjective Success Evaluations

We hypothesize that career success assessed as objective career achievements (income and responsibility status) has an indirect positive association with life satisfaction that is channeled through multiple subjective success evaluations. These are based on (a) social comparisons (comparison with others, other-referent success evaluation) and (b) individual standards (satisfaction with career achievements, self-referent success evaluations). We tested our reasoning in a 2-year prospective study with N = 990 professionals. Controlling for gender, family status, and workload, the results of two mediation models that draw on all information from two measurement points supported our reasoning. We found indirect positive associations between career success and life satisfaction (H1) channeled through both other-referent (H2) and self-referent (H3) subjective success evaluation. In both mediation models, we found partial mediation, and the remaining direct path from career success to life satisfaction was negative. We conclude that career success has mixed effects on a person’s life satisfaction: The net effect of positive indirect and negative direct effects is positive, but not large. We discuss the significance of these findings for theorizing about the influence of the work domain on life satisfaction as well as for conceptual issues in the analysis of mediators and moderators of the career success life satisfaction association.     

What Am I Looking at? Interpreting Dynamic and Static Gaze Displays

Displays of eye movements may convey information about cognitive processes but require interpretation. We investigated whether participants were able to interpret displays of their own or others' eye movements. In Experiments 1 and 2, participants observed an image under three different viewing instructions. Then they were shown static or dynamic gaze displays and had to judge whether it was their own or someone else's eye movements and what instruction was reflected. Participants were capable of recognizing the instruction reflected in their own and someone else's gaze display. Instruction recognition was better for dynamic displays, and only this condition yielded above chance performance in recognizing the display as one's own or another person's (Experiments 1 and 2). Experiment 3 revealed that order information in the gaze displays facilitated instruction recognition when transitions between fixated regions distinguish one viewing instruction from another. Implications of these findings are discussed.
