Rewarding performance feedback alters reported time of action

Past studies have shown that the perceived time of actions is retrospectively influenced by post-action events. The current study examined whether rewarding performance feedback (even when false) altered the reported time of action. In Experiment 1, participants performed a speeded button press task and received monetary reward for a presumed “fast,” or a monetary punishment for a presumed “slow” response. Rewarded trials resulted in the false perception that the response action occurred earlier than punished trials. In Experiments 2 and 3, the need for a speeded response and reward were independently manipulated in order to decouple the cognitive and reward components in the feedback signal. When tested independently, neither variable affected the judged time of action. We conclude that meaningful feedback (fast or slow) is only used when made salient by reward, to modulate the judged time of an action.     

Individual differences in time perspective predict autonoetic experience

Tulving (1985) posited that the capacity to remember is one facet of a more general capacity—autonoetic (self-knowing) consciousness. Autonoetic consciousness was proposed to underlie the ability for “mental time travel” both into the past (remembering) and into the future to envision potential future episodes (episodic future thinking). The current study examines whether individual differences can predict autonoetic experience. Specifically, the Zimbardo Time Perspective Inventory (ZTPI, Zimbardo & Boyd, 1999) was administered to 133 undergraduate students, who also rated phenomenological experiences accompanying autobiographical remembering and episodic future thinking. Scores on two of the five subscales of the ZTPI (Future and Present-Hedonistic) predicted the degree to which people reported feelings of mentally traveling backward (or forward) in time and the degree to which they reported re- or pre-experiencing the event, but not ten other rated properties less related to autonoetic consciousness.     

Role of face‐to‐face and computer‐mediated communication time in the cohesion and performance of mixed‐mode groups

Although the rapid development of information technology has led to the increasing use of computer‐mediated communication (CMC), few studies have examined the relational aspect of mixed‐mode groups that use both face‐to‐face (FTF) communication and CMC. A field study comprising 42 student groups was conducted to assess the relationships among communication time, cohesion, and performance in mixed‐mode groups. The findings suggest that time spent in FTF communication significantly predicted group social cohesion, but time spent in CMC did not. In contrast, group task cohesion was predicted by time spent in CMC but not by time spent in FTF communication. Time spent in CMC was also a strong predictor of group task performance. These results suggest that FTF communication contributes to the social aspect of mixed‐mode groups and that CMC is beneficial to their task‐related aspect. The findings of mediation analyses showed a significant indirect effect among time spent in FTF communication, group social cohesion, and group contextual performance. In other words, time spent in FTF communication had a positive effect on group social cohesion, which in turn positively affected group contextual performance. However, no mediating effect was found among time spent in CMC, group task cohesion, and group task performance. Theoretical and practical implications of these findings are discussed.     

Effects of listening to music, and of using a handheld and handsfree telephone on cycling behaviour

The effects of listening to music on cycling behaviour were evaluated. Twenty-five participants completed a track on a bicycle while listening to music with two standard earbuds, with one earbud, and with two in-earbuds. Conditions with high tempo music and loud volume were also included in the experiment, as were two mobile phone conditions, one in which participants operated the phone hand held and one handsfree condition.Cycle speed was not affected by listening to music, but was reduced in the telephone conditions. In general the response to auditory signals worsened when participants listened to music, in particular when listening with in-earbuds loud auditory stop signals were missed in 68% of the cases. However, when listening with only one standard earbud performance was not affected. In the conditions when participants listened to high volume and to high tempo music, the auditory stop signal was also heard in significantly fewer cases. Completing a task on the mobile phone, using both handheld and handsfree sets, resulted in increased response time to an auditory stop signal and also reduced overall auditory perception. Furthermore, handsfree operation only had minor advantages opposed to hand held operation, with only response time to an auditory stop signal resulting in faster performance. This is likely to be related to the fact that both hands could be used for braking.It is concluded that listening to music worsens auditory perception, in particular if in-earbuds are used. Furthermore, both handheld and handsfree operation of mobile phones has a negative effect on perception, potentially forming a threat to cyclist traffic safety.     

Response speed as an individual difference: Its role in moderating the agreeableness-anger relationship

Anger is an emotion that is precipitated by hostile attitudes and high arousal. The trait of agreeableness is a moderately inverse predictor of hostile attitudes and anger. Relations between agreeableness and anger are likely to be stronger to the extent that the person can be characterized as high in dispositional arousal. Arousal-related manipulations speed responses in cognitive tasks. Thus, individual differences in response speed may be informative concerning general tendencies toward aroused states. In three studies (N = 319) individual differences in response speed in basic choice tasks interacted with agreeableness to predict state-related experiences of anger. Specifically, the highest levels of anger were observed among fast/disagreeable individuals. The utility of this probe in future studies is discussed.     

Hypermaturity and Immaturity of Personality Profiles in Adolescents

Five‐year longitudinal data on a cohort of early to middle adolescents (N = 923) and a cohort of middle to late adolescents (N = 390) were used to examine the correlates of hypermaturity (i.e. 12‐year‐olds with a personality profile resembling the profile of an average 20‐year‐old) and immaturity (i.e. 20‐year‐olds with a personality profile resembling the profile of an average 12‐year‐old) of personality. Analyses revealed that girls with high levels of hypermaturity exhibited high levels of internalizing problem behaviour and conflict with parents, while hypermaturity in boys was only associated with internalizing problems. Immature girls had low levels of anxiety and high levels of minor delinquency, whereas immature boys reported low levels of anxiety and high levels of physical maturity. These findings suggest that off‐time personality development is an interesting concept deserving further exploration. Copyright © 2011 John Wiley & Sons, Ltd.     

Effects of access to a stimulating object on infant behavior during tummy time

Placing infants in a prone position for "tummy time" often is recommended to ensure appropriate infant development and to combat the effects associated with infants spending extended periods of time in a supine position. However, tummy time may be associated with inappropriate infant behavior such as crying and noncompliance. We provided continuous access to a preferred stimulus to decrease negative vocalizations and to increase the duration of an infant's head being elevated during tummy time.     

Acceptability of Personal Hormone Monitoring for Contraception: Longitudinal and Contextual Variables

Abstract

A new contraceptive technology may advance the science of family planning but may do little to affect health if potential users do not deem it an acceptable method. The authors conducted an acceptability study of a newly developed contraceptive method–personal hormone monitoring. A sample of 480 English volunteers present at the 6th month of a 13-month longitudinal study completed surveys regarding their attitudes toward a personal hormone monitor for the purpose of contraception. The authors used the participants' responses to determine (a) the extent to which the participants accepted the monitor, (b) how their ratings of acceptability changed over time, (c) the extent to which contextual variables predicted changes in acceptability over time, and (d) whether those contextual variables predicted final acceptability of the monitor. Results suggested that no single method of family planning is best for everyone and specified the people for whom personal hormone monitoring may be most suitable.     

Exploring the Interactive Effect of Time Control and Justice Perception on Job Attitudes

ABSTRACT

We investigated the associations between supervisor-related time control and two-job attitudes, and the moderating effects of distributive justice on these associations. A total of 505 full-time employees in Hong Kong responded to a structured telephone survey. The results showed that time control and perceived distributive justice were positively related to both job satisfaction and organizational commitment. More importantly, the positive relationships between time control and the two job attitudes were stronger when perceived distributive justice was high rather than low. These findings contrast with the typical buffering effects of organizational justice, in which perceived justice attenuates the beneficial effects of positive stimuli. Theoretical and applied implications of these findings are discussed.
