Age-related positivity effects and autobiographical memory detail: Evidence from a past/future source memory task

This study investigated whether the age-related positivity effect strengthens specific event details in autobiographical memory. Participants retrieved past events or imagined future events in response to neutral or emotional cue words. Older adults rated each kind of event more positively than younger adults, demonstrating an age-related positivity effect. We next administered a source memory test. Participants were given the same cue words and tried to retrieve the previously generated event and its source (past or future). Accuracy on this source test should depend on the recollection of specific details about the earlier generated events, providing a more objective measure of those details than subjective ratings. We found that source accuracy was greater for positive than negative future events in both age groups, suggesting that positive future events were more detailed. In contrast, valence did not affect source accuracy for past events in either age group, suggesting that positive and negative past events were equally detailed. Although ageing can bias people to focus on positive aspects of experience, this bias does not appear to strengthen the availability of details for positive relative to negative past events.     

Social comparisons and quality of life among survivors of childhood cancer and their mothers

Abstract

Sixty-three survivors of childhood cancer (mean age 17 years), currently well and off-treatment, and their mothers were interviewed individually about their experiences and the impact of their illness on their lives. Survivors also completed four questionnaire measures of different aspects of quality of life (perceptions of illness experience, future worries, health problems and body image satisfaction), whereas mothers recorded their perceptions of their child's quality of life on the same four scales. These scales showed good internal consistency and convergent validity for both survivors and mothers. Mothers also completed a measure of their own quality of life (the SF-36). The interviews with both survivors and mothers were content-analysed for statements expressing social comparisons. These statements were coded according to whether the comparison implied a favourable, neutral or unfavourable evaluation of the individual survivor. Mothers who made a higher proportion of unfavourable comparisons reported worse adjustment for their child on all four scales and described their own quality of life more negatively. Among survivors, those who made a higher proportion of unfavourable comparisons gave significantly more negative self-ratings on one of the four scales. Correlations between survivors' and mothers' ratings on the four scales were positive, but comparatively low. This reinforces concerns about using parents as proxy judges of young people's quality of life, although the correlations were more satisfactory in the case of younger rather than older (>18.5 years) survivors. Mothers who rated their own quality of life as less satisfactory reported more problems for their child on all four scales, irrespective of how the survivors described themselves.     

Approaching Success or Avoiding Failure? Approach and Avoidance Motives in the Work Domain

In our set of studies, we extended research on approach and avoidance motivations by investigating (i) motives in a work setting, (ii) interactions among approach and avoidance motives, and (iii) motives at implicit levels. Results of Studies 1 through 3 provided support for the construct validity of our work motives measure by demonstrating that approach and avoidance work motives are markers of more general approach and avoidance temperaments, they are distinct from other individual difference variables commonly studied by organisational psychologists (e.g. conscientiousness, regulatory focus and cognitive ability) and they are stable over time. In Studies 4 through 7, we confirmed our predictions that approach and avoidance motives predict employees' goal orientations, job appraisals and attitudes (e.g. job satisfaction and perceived support) and supervisor‐rated job behaviours (e.g. task performance and citizenship behaviour). Importantly, we provide the first empirical evidence that approach and avoidance motives interact to predict task performance and that the motives operate at implicit levels.

The role of response inhibition in temporal preparation: Evidence from a go/no-go task

During the foreperiod (FP) of a warned reaction task, participants engage in a process of temporal preparation to speed response to the impending target stimulus. Previous neurophysiological studies have shown that inhibition is applied during FP to prevent premature response. Previous behavioral studies have shown that the duration of FP on both the current and the preceding trial codetermine response time to the target. Integrating these findings, the present study tested the hypothesis that the behavioral effects find their origin in response inhibition on the preceding trial. In two experiments the variable-FP paradigm was combined with a go/no-go task, in which no-go stimuli required explicit response inhibition. The resulting data pattern revealed sequential effects of both FP (long or short) and response requirement (go or no-go), which could be jointly understood as expressions of response inhibition, consistent with the hypothesis.     

Counting the Faithful: Measuring Local Religious Contexts in the United States

This study compares the estimates of religious composition of counties in the United States from three independent datasets: the 2010 Religious Congregational Membership Study (RCMS); the 2010 Infogroup Congregational membership data (INFO); and the Gallup Daily Poll—a large national survey with more than 1.3 million respondents. My analyses suggest that the estimates for most major religious groups from the three datasets are highly correlated to each other. In addition, the measures of local religious compositions from the three datasets successfully predict the religious composition of friendship networks in a large, nationally representative survey. These findings suggest that RCMS, the most widely used data source for measuring local religious composition in the United States, has a convergent and predictive validity. My analyses, however, also highlight important challenges in measuring geographic distributions of non‐Christian populations, as well as total religious populations in all religious traditions.     

The influence of spatial representation on valence judgements: An event-related potential study

The present study used event-related potentials (ERPs) to explore the nature of space-valence congruency effects. We presented participants with up or down arrows at the centre of the screen and then asked participants to identify whether the following target words had the emotional valence. The target words included positive emotional words (e.g., “happy” and “delight”), negative emotional words (e.g., “sad” and “depressive”) and neutral words (e.g., “history” and “country”). Behavioural data showed that the positive targets were identified faster when they are primed by up arrows than when primed by down arrows, whereas the negative targets were identified faster when they are primed by down arrows than when primed by up arrows. The ERP analysis showed larger P2 amplitudes were found in the congruent condition (i.e., the positive targets following up arrows or the negative targets following down arrows) than in the incongruent condition (i.e., the positive targets following down arrows or the negative targets following up arrows). Furthermore, larger N400 amplitudes were found in the incongruent condition compared with the congruent condition. Moreover, larger LPC amplitudes were found in the congruent condition compared with the incongruent condition. Therefore, in addition to replicating the space-valence congruency effects in a neutral/emotional judgement task, our study also extended previous studies by showing that spatial information modulates the processing of the emotional words at multiple stages.     

Variability and recognition memory: Are there analogous indexical effects in music and speech?

Indexical effects refer to the influence of surface variability of the to-be-remembered items, such as different voices speaking the same words or different timbres (musical instruments) playing the same melodies, on recognition memory performance. The nature of timbre effects in melody recognition was investigated in two experiments. Experiment 1 showed that melodies that remained in the same timbre from study to test were discriminated better than melodies presented in a previously studied but different, or unstudied timbre at test. Timbre effects are attributed solely to instance-specific matching, rather than timbre-specific familiarity. In Experiment 2, when a previously unstudied timbre was similar to the original timbre and it played the melodies at test, performance was comparable to the condition when the exact same timbre was repeated at test. The use of a similar timbre at test enabled the listener to discriminate old from new melodies reliably. Overall, our data suggest that timbre-specific information is encoded and stored in long-term memory. Analogous indexical effects arising from timbre (nonmusical) and voice (nonlexical) attributes in music and speech processing respectively are implied and discussed.     

Video game experience and its influence on visual attention parameters: An investigation using the framework of the Theory of Visual Attention (TVA)

Experts with video game experience, in contrast to non-experienced persons, are superior in multiple domains of visual attention. However, it is an open question which basic aspects of attention underlie this superiority. We approached this question using the framework of Theory of Visual Attention (TVA) with tools that allowed us to assess various parameters that are related to different visual attention aspects (e.g., perception threshold, processing speed, visual short-term memory storage capacity, top-down control, spatial distribution of attention) and that are measurable on the same experimental basis. In Experiment 1, we found advantages of video game experts in perception threshold and visual processing speed; the latter being restricted to the lower positions of the used computer display. The observed advantages were not significantly moderated by general person-related characteristics such as personality traits, sensation seeking, intelligence, social anxiety, or health status. Experiment 2 tested a potential causal link between the expert advantages and video game practice with an intervention protocol. It found no effects of action video gaming on perception threshold, visual short-term memory storage capacity, iconic memory storage, top-down control, and spatial distribution of attention after 15 days of training. However, observations of a selected improvement of processing speed at the lower positions of the computer screen after video game training and of retest effects are suggestive for limited possibilities to improve basic aspects of visual attention (TVA) with practice.     

Do the Effects of Adolescent Employment Differ by Employment Intensity and Neighborhood Context?

Research on the effects of adolescent employment on primarily middle‐class youth suggests that intense employment, working more than 15 or 20 hours during the school year, is associated with increased participation in risky behavior. Despite these findings, scholars who focus on the development of youth living in low‐income urban areas often hypothesize that adolescent employment will have beneficial effects on this population. There is some evidence that adolescent employment is associated with increased educational achievement and adult employment for low‐income urban youth. The impact of adolescent employment on future engagement in risky behavior across levels of neighborhood deprivation and employment intensity was investigated on a sample of 1,057 adolescents from the Project on Human Development in Chicago Neighborhoods, a longitudinal study of neighborhood effects on development. After controlling for individual characteristics, intense employment during adolescence did predict increased use of cigarettes and alcohol and having a greater number of sexual partners 2 years after employment was measured. There were no significant interactions between neighborhood SES and adolescent employment status on involvement in risky behavior. These findings suggest that intense adolescent employment is associated with detrimental developmental outcomes for youth regardless neighborhood context.     

Personality links to anger: Evidence for trait interaction and differentiation across expression style

Anger is a commonly experienced emotion, although marked individual differences in the expression of anger are observed. Basic dimensions of personality (e.g., Big Five traits) have been shown to predict the experience of trait anger; however, little work has addressed the personality correlates of broader conceptualisations of trait anger (e.g., inward or outward expressions). Additionally, while some recent work has suggested that basic personality traits may show interactive influences on anger expression this work has yet to be independently confirmed. In a large sample of adults we examined, firstly, how Big Five traits associated with several components of anger as measured by the State-Trait Anger Expression Inventory. Secondly, we examined whether these associations were further qualified by interactions between Big Five traits. Results indicated neuroticism and, to a lesser extent, (low) agreeableness, were the traits most associated with components of trait anger. Conscientiousness and extraversion were also noted to show links to more focal components of anger. Moderation was observed: conscientiousness moderated neuroticism’s relationship with anger control, and agreeableness and conscientiousness, in a three-way interaction, moderated neuroticism’s relationship with trait anger. These observations help to further clarify the role of Big Five personality traits as a foundation for the experiences of anger, demonstrating how anger style varies across personality configuration.
