Determinants of the shape of emotion intensity profiles

It has been shown that variability in the shape of emotion intensity profiles can be described in terms of three functional features, namely steepness at onset, skewness and number of peaks. However, it remains unclear which factors account for variability in each of these features. In the present study participants were asked to report intensity profiles of positive and negative emotions on a daily basis. Information was further collected regarding potential determinants of the functional features of the intensity profiles at three levels: trait-, episode-, and moment-determinants. Regarding steepness at onset, it was found for positive and negative emotions that intensity profiles have an especially explosive start when the eliciting stimulus is important, when the stimulus is still present during the beginning of the episode, and, in case of positive emotions, when the participant is an extravert. Concerning skewness, it was found for positive and negative emotions that profiles reach their peak more often towards the end when the eliciting stimulus is important, when the stimulus is absent during the beginning of the episode but present towards the end, and, in case of negative emotions, when the stimulus is uncontrollable. Regarding the number of peaks, it was found that profiles more often have multiple peaks when the eliciting stimulus is absent during the middle of the emotional episode.     

Using guided reading to teach internet inquiry skills: a case study of one elementary school teacher’s experience

Employees in the twenty-first century must be equipped to effectively process information from print and online sources; yet, many students struggle with online research and comprehension skills, making them ill-prepared in college and careers. Utilizing a qualitative exploratory case study design, this study describes how a fourth-grade teacher developed her students’ online research and comprehension skills in small groups using the guided reading framework to frame her instruction. Key findings suggest that the teacher adapted many components of the guided reading framework to develop students’ online inquiry skills. Both the teacher and students experienced role changes and challenges related to the experience, yet students demonstrated high rates of engagement and collaboration. This paper provides a situated example of how a teacher adapted an existing instructional context in her classroom and implications for adapting other popular instructional context, frameworks, and models for supporting teachers in developing students’ digital literacy skills.     

Self-transcendent positive emotions increase spirituality through basic world assumptions

Spirituality has mostly been studied in psychology as implied in the process of overcoming adversity, being triggered by negative experiences, and providing positive outcomes. By reversing this pathway, we investigated whether spirituality may also be triggered by self-transcendent positive emotions, which are elicited by stimuli appraised as demonstrating higher good and beauty. In two studies, elevation and/or admiration were induced using different methods. These emotions were compared to two control groups, a neutral state and a positive emotion (mirth). Self-transcendent positive emotions increased participants' spirituality (Studies 1 and 2), especially for the non-religious participants (Study 1). Two basic world assumptions, i.e., belief in life as meaningful (Study 1) and in the benevolence of others and the world (Study 2) mediated the effect of these emotions on spirituality. Spirituality should be understood not only as a coping strategy, but also as an upward spiralling pathway to and from self-transcendent positive emotions.     

Attentional prioritisation of threatening information: Examining the role of the size of the attentional window

In line with most models of emotion, research has shown that threatening information receives attentional priority over neutral information. Recently, it has been suggested that the degree to which participants divide their attention across the visual field (the attentional window) may modulate the extent to which salient objects are attentionally prioritised. In the current study, participants were required to identify a target inside one of a variable number of coloured circles. One colour (Conditioned Stimulus, CS +) was fear-conditioned using an electrocutaneous stimulus at tolerance level. This search task was combined with a go/no-go task that required participants to either divide attention across the visual field to create a broad attentional window (global group), or focus their attention on the fixation point to create a narrow attentional window (local group). The results showed that only in the global group was the CS + colour prioritised over the neutral colours, indicating that a broader attentional window leads to enhanced attentional prioritisation of threat. Implications for research on attentional bias to threat are discussed.     

Cognitive control and attentional functions

Cognitive control is essential to flexible, goal-directed behavior under uncertainty, yet its underlying mechanisms are not clearly understood. Because attentional functions are known to allocate mental resources and prioritize the information to be processed, we propose that the attentional functions of alerting, orienting, and executive control and the interactions among them contribute to cognitive control in the service of uncertainty reduction. To test this hypothesis, we examined the relationship between cognitive control and attentional functions. We used the Majority Function Task (MFT) to manipulate uncertainty in order to evoke cognitive control along with the Revised Attention Network Test (ANT-R) to measure the efficiency and the interactions of attentional functions. A backwards, stepwise regression model revealed that performance on the MFT could be significantly predicted by attentional functions and their interactions as measured by the ANT-R. These results provide preliminary support for our theory that the attentional functions are involved in the implementation of cognitive control as required to reduce uncertainty, though further investigation is needed.     

Effects of visual information regarding allocentric processing in haptic parallelity matching

Research has revealed that haptic perception of parallelity deviates from physical reality. Large and systematic deviations have been found in haptic parallelity matching most likely due to the influence of the hand-centered egocentric reference frame. Providing information that increases the influence of allocentric processing has been shown to improve performance on haptic matching. In this study allocentric processing was stimulated by providing informative vision in haptic matching tasks that were performed using hand- and arm-centered reference frames.     

Enhancing inhibition: How impulsivity and emotional activation interact with different implementation intentions

Implementation intentions, a strategy in which a strong link is created between a cue and a to-be-performed action, have been shown to be efficacious in improving self-regulation. The relative efficacy of verbal and visual implementation intentions, however, has yet to be determined. Implementation intentions have also been shown to be inefficacious in participants with high impulsivity, specifically in individuals who reported having a high tendency to commit rash or regrettable actions as a result of intense affect (high urgency). Nevertheless, previous studies did not assess whether the individuals were in an emotional context at the time of the experiment. In the current study, we compared different forms of implementation intentions (verbal/visual/combined verbal–visual) on a computerized inhibition task while assessing impulsivity and emotional activation. The results showed that all types of implementation intentions improved inhibition performances significantly in participants with high urgency, but only when their emotional activation was low. There was no difference between the three types of implementation intentions.     

Identity but not expression memory for unfamiliar faces is affected by ageing

We examined age‐related differences in memory for identity and emotional expression of unfamiliar faces. Younger and older adults were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. When a face was recognised, they also had to remember what the initial expression of the face had been. In addition, states of awareness associated with both identity and expression memory were assessed with the remember/know/guess paradigm. Older adults showed less recollective experience than younger adults for identity but not for emotional expressions of the faces. This evidence indicates that age‐related differences in memory may depend on the nature of the to‐be‐remembered information, with emotional/social information being remembered as well in older as in younger adults.     

Directed forgetting in working memory: Age‐related differences

This study explored the effects of ageing on working memory by means of the directed forgetting procedure designed by Reed (1970). Memory for a letter trigram was compared in conditions where it was either presented alone (single‐item), or followed by a second trigram to be recalled (interference), or followed by a second trigram to be forgotten (directed forgetting). The results clearly indicated that elderly participants inhibited the no‐longer‐relevant information less efficiently (recall in the single‐item condition – recall in the directed forgetting condition), as predicted by the model of Hasher and Zacks (1988). However, the results also demonstrated that sensitivity to interference (recall in the single‐item condition – recall in the interference condition) increased in the condition in which no inhibition was directly required.     

The effect of ageing on the recollection of emotional and neutral pictures

This study investigated age-related differences in recognition memory for emotional and neutral pictures. Younger and older participants were asked to rate pictures according to their emotional valence, arousal, and visual complexity. Two weeks later they had to recognise these pictures and the states of awareness associated with memory were assessed with the “remember/know/guess” paradigm. We found that, although the influence of emotion on recognition accuracy (as assessed by d′) was similar in both age groups, the tendency for positive and negative pictures to create a rich recollective experience was weaker in older adults. In addition, “remember” responses were more often based on a recollection of emotional reactions in older than in younger participants. We suggest that the elderly tend to focus on their feelings when confronted with emotional pictures, which could have impaired their memory for the contextual information associated with these stimuli.
