Just the facts or just for fun? Children's understanding of and sensitivity to retelling contexts

Adults appear to recognize that different memory sharing contexts, such as telling a story to a friend at a party versus providing eyewitness testimony, vary in their accuracy demands and adjust their retellings accordingly. There is less evidence that children are able to make the same distinctions. In the present two‐part experiment, we first tested 6–8‐year‐old children's beliefs about the accuracy requirements of different memory sharing contexts that varied on the listener's implicit expectation about accuracy. Children were then read a short story and were given retelling instructions that emphasized accuracy or entertainment. Results from the first task indicated that children evidence a significant truth bias, suggesting that they believe accurate retellings are preferred regardless of context. Despite this, children did appear to adjust their retellings as a function of context, with retellings in the high accuracy condition including more verbatim and less error statements. Finally, children who evidenced a stronger truth bias were less likely to employ the language of storytelling by producing lower‐quality narratives. Copyright © 2010 John Wiley & Sons, Ltd.     

Social exchange styles: Measurement,validation, and application

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Dream rebound of suppressed emotional thoughts: the influence of cognitive load

Initial evidence suggests that suppressing a thought prior to sleep results in subsequent dreaming of that thought. The present research examined the influence of cognitive load on dreaming following suppression. In Experiment 1, 100 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and subsequently completed a dream diary. Participants instructed to suppress reported dreaming about the target thought more than controls; dream rebound was predicted by poorer performance on a working memory task. In Experiment 2, 126 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and half of participants also had cognitive load of learning a 9-digit number. Participants receiving the suppression instruction under cognitive load reported greater dream rebound than other participants. These findings indicate that thought suppression prior to sleep leads to dream rebound, and this effect is enhanced by cognitive load.     

Conceptual similarity promotes generalization of higher order fear learning

We tested the hypothesis that conceptual similarity promotes generalization of conditioned fear. Using a sensory preconditioning procedure, three groups of subjects learned an association between two cues that were conceptually similar, unrelated, or mismatched. Next, one of the cues was paired with a shock. The other cue was then reintroduced to test for fear generalization, as measured by the skin conductance response. Results showed enhanced fear generalization that correlated with trait anxiety levels in the group that learned an association between conceptually similar stimuli. These findings suggest that conceptual representations of conditional stimuli influence human fear learning processes.     

The effect of induced anxiety on cognition: threat of shock enhances aversive processing in healthy individuals

Individuals with anxiety disorders demonstrate altered cognitive performance including (1) cognitive biases towards negative stimuli (affective biases) and (2) increased cognitive rigidity (e.g., impaired conflict adaptation) on affective Stroop tasks. Threat of electric shock is frequently used to induce anxiety in healthy individuals, but the extent to which this manipulation mimics the cognitive impairment seen in anxiety disorders is unclear. In this study, 31 healthy individuals completed an affective Stroop task under safe and threat-of-shock conditions. We showed that threat (1) enhanced aversive processing and abolished a positive affective bias but (2) had no effect on conflict adaptation. Threat of shock thus partially models the effects of anxiety disorders on affective Stroop tasks. We suggest that the affective state of anxiety—which is common to both threat and anxiety disorders—modulates the neural inhibition of subcortical aversive processing, whilst pathologies unique to anxiety disorders modulate conflict adaptation.     

Has cyber technology produced a new group of peer aggressors?

Cyber technology provides a new venue for the expression of aggression. However, whether cyber technology has produced a new group of peer aggressors or simply allowed aggressive peers new tools to victimize others is unclear. This study sampled 1,672 adolescents to assess their engagement in cyber aggression. Although "cyber," "overt," and "relational" represent distinct subtypes of aggressive behavior, our results indicate that adolescents' behaviors clustered according to their frequency-not type-of aggression. Thus cyber technology provides new tools for youth who already engage in aggressive behaviors in the physical world to victimize peers in cyberspace.     

Functional analysis and treatment of human-directed undesirable behavior exhibited by a captive chimpanzee

A functional analysis identified the reinforcer maintaining feces throwing and spitting exhibited by a captive adult chimpanzee (Pan troglodytes). The implementation of a function-based treatment combining extinction with differential reinforcement of an alternate behavior decreased levels of inappropriate behavior. These findings further demonstrate the utility of function-based approaches to assess and treat behavior problems exhibited by captive animals.     

The relations of daily task accomplishment satisfaction with changes in affect: a multilevel study in nurses

Focusing on a sample of nurses, this investigation examined the relationships of daily task accomplishment satisfaction (for direct and indirect care tasks) with changes in positive and negative affect from preshift to postshift. Not accomplishing tasks to one's satisfaction was conceptualized as a daily workplace stressor that should increase daily negative affect and decrease daily positive affect from preshift to postshift. Further, because of the greater centrality of direct care nursing tasks to nursing work role identities (relative to indirect care tasks), we expected that task accomplishment satisfaction (or lack thereof) for these tasks would have stronger effects on changes in affect than would task accomplishment satisfaction for indirect care tasks. We also examined 2 person-level resources, collegial nurse-physician relations and psychological resilience, as moderators of the relationships among these daily variables, with the expectation that these resources would buffer the harmful effects of low task accomplishment satisfaction on nurse affect. Results supported almost all of the proposed effects, though the cross-level interactions were observed only for the effects of indirect care task accomplishment satisfaction on affect and not for direct care task accomplishment satisfaction on affect.     

Measurement of Preoperative Anxiety in Young Children: Self-report Versus Observer-rated

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used, observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS), and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy.     

The Social Nature of Engineering and its Implications for Risk Taking

Making decisions with an, often significant, element of risk seems to be an integral part of many of the projects of the diverse profession of engineering. Whether it be decisions about the design of products, manufacturing processes, public works, or developing technological solutions to environmental, social and global problems, risk taking seems inherent to the profession. Despite this, little attention has been paid to the topic and specifically to how our understanding of engineering as a distinctive profession might affect how we should make decisions under risk. This paper seeks to remedy this, firstly by offering a nuanced account of risk and then by considering how specific claims about our understanding of engineering as a social profession, with corresponding social values and obligations, should inform how we make decisions about risk in this context.
