The Effect of Limited Attention and Delay on Negative Arousing False Memories
Previous research has shown that, in comparison to neutral stimuli, false memories for high arousing negative stimuli are greater after very fast presentation and limited attention at study. However, full compared to limited attention conditions still produce comparably more false memories for all stimuli types. Research has also shown that emotional stimuli benefit from a period of consolidation. What effect would such consolidation have on false memory formation even when attention is limited at study? The aim of the present study was to investigate the effect of fast presentation on false memory production for negatively-arousing and neutral items over time using the DRM paradigm. Sixty-Eight participants studied Negative and neutral DRM lists with fast or slow presentation conditions. Half completed a recognition test immediately and half completed a recognition test after one-week. Results revealed that, for fast presentation, negative critical lures increased after one week and were comparable to negative critical lures in the slow presentation encoding conditions. Neutral critical lures in the fast presentation condition did not change and remained lower compared to the slow presentation condition. These findings are the first demonstration that arousing negative false memories can increase over time when attention at encoding is limited
Spreading the virus : emotional tone of viral advertising and its effect on forwarding intentions and attitudes
iral advertising has attracted advertisers in recent years, yet little is known about how exactly it works from an information processing perspective. This study extends knowledge by exploring how the emotional tone (pleasant, unpleasant, coactive) of viral video ads affects attitude toward the ad, attitude toward the brand, and forwarding intentions. Results indicate that pleasant emotional tone elicits the strongest attitude toward the ad, attitude toward the brand, and intention to forward. The effects were weaker for coactive tone and weakest for negative emotional tone. These results challenge the common approach of shocking or scaring online users to motivate them to forward a viral video
Multi-Moji: Combining Thermal, Vibrotactile and Visual Stimuli to Expand the Affective Range of Feedback
This paper explores the combination of multiple concurrent
modalities for conveying emotional information in HCI:
temperature, vibration and abstract visual displays. Each modality
has been studied individually, but can only convey a
limited range of emotions within two-dimensional valencearousal
space. This paper is the first to systematically combine
multiple modalities to expand the available affective
range. Three studies were conducted: Study 1 measured the
emotionality of vibrotactile feedback by itself; Study 2 measured
the perceived emotional content of three bimodal combinations:
vibrotactile + thermal, vibrotactile + visual and
visual + thermal. Study 3 then combined all three modalities.
Results show that combining modalities increases the available
range of emotional states, particularly in the problematic
top-right and bottom-left quadrants of the dimensional
model. We also provide a novel lookup resource for designers
to identify stimuli to convey a range of emotions
What makes music memorable? Relationships between acoustic musical features and music-evoked emotions and memories in older adults
Background and objectives Music has a unique capacity to evoke both strong emotions and vivid autobiographical memories. Previous music information retrieval (MIR) studies have shown that the emotional experience of music is influenced by a combination of musical features, including tonal, rhythmic, and loudness features. Here, our aim was to explore the relationship between music-evoked emotions and music-evoked memories and how musical features (derived with MIR) can predict them both. Methods Healthy older adults (N = 113, age ≥ 60 years) participated in a listening task in which they rated a total of 140 song excerpts comprising folk songs and popular songs from 1950s to 1980s on five domains measuring the emotional (valence, arousal, emotional intensity) and memory (familiarity, autobiographical salience) experience of the songs. A set of 24 musical features were extracted from the songs using computational MIR methods. Principal component analyses were applied to reduce multicollinearity, resulting in six core musical components, which were then used to predict the behavioural ratings in multiple regression analyses. Results All correlations between behavioural ratings were positive and ranged from moderate to very high (r = 0.46–0.92). Emotional intensity showed the highest correlation to both autobiographical salience and familiarity. In the MIR data, three musical components measuring salience of the musical pulse (Pulse strength), relative strength of high harmonics (Brightness), and fluctuation in the frequencies between 200–800 Hz (Low-mid) predicted both music-evoked emotions and memories. Emotional intensity (and valence to a lesser extent) mediated the predictive effect of the musical components on music-evoked memories. Conclusions The results suggest that music-evoked emotions are strongly related to music-evoked memories in healthy older adults and that both music-evoked emotions and memories are predicted by the same core musical features.Peer reviewe
The emotion potential of words and passages in reading Harry Potter:an fMRI study
Previous studies suggested that the emotional connotation of single words automatically recruits attention. We investigated the potential of words to induce emotional engagement when reading texts. In an fMRI experiment, we presented 120 text passages from the Harry Potter book series. Results showed significant correlations between affective word (lexical) ratings and passage ratings. Furthermore, affective lexical ratings correlated with activity in regions associated with emotion, situation model building, multi-modal semantic integration, and Theory of Mind. We distinguished differential influences of affective lexical, inter-lexical, and supra-lexical variables: differential effects of lexical valence were significant in the left amygdala, while effects of arousal-span (the dynamic range of arousal across a passage) were significant in the left amygdala and insula. However, we found no differential effect of passage ratings in emotion-associated regions. Our results support the hypothesis that the emotion potential of short texts can be predicted by lexical and inter-lexical affective variables
Evaluation of Neutral Words as a Function of Affective Semantic Associates
How do humans perform difficult forced-choice evaluations, e.g., of words that
have been previously rated as being neutral? Here we tested the hypothesis
that in this case, the valence of semantic associates is of significant
influence. From corpus based co-occurrence statistics as a measure of
association strength we computed individual neighborhoods for single neutral
words comprised of the 10 words with the largest association strength. We then
selected neutral words according to the valence of the associated words
included in the neighborhoods, which were either mostly positive, mostly
negative, mostly neutral or mixed positive and negative, and tested them using
a valence decision task (VDT). The data showed that the valence of semantic
neighbors can predict valence judgments to neutral words. However, all but the
positive neighborhood items revealed a high tendency to elicit negative
responses. For the positive and negative neighborhood categories responses
congruent with the neighborhood's valence were faster than incongruent
responses. We interpret this effect as a semantic network process that
supports the evaluation of neutral words by assessing the valence of the
associative semantic neighborhood. In this perspective, valence is considered
a semantic super-feature, at least partially represented in associative
activation patterns of semantic networks
