Late Finnish–English bilinguals were presented with neutral, positive, negative and taboo words in a modified Stroop paradigm both Finnish English. Significant interference from compared to neutral was found languages, whereas positive not differ significantly words. Furthermore, no differences the size of present between languages. This suggests that, for late good knowledge their second language, first (L1) (L2) language are equally capable activating emotional response word stimuli...

Skin conductance levels (SCLs) of native and non-native English speakers were measured during emotional taboo Stroop tasks. Significantly slower response times to negative words when compared neutral found in both groups participants, but positive not differ significantly from words. No differences between their behavioural responses present: the pattern interference was be identical L1 L2. SCLs, however, did reveal participants: responded with higher SCLs This difference observed speakers,...

Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, are they cultural creations learned through languages and traditions? To answer these questions, we tested emotional colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts 12 color terms. Pattern-similarity analyses revealed universal (average similarity coefficient r = .88)....

The link between colour and emotion its possible similarity across cultures are questions that have not been fully resolved. Online, 711 participants from China, Germany, Greece the UK associated 12 terms with 20 discrete in their native languages. We propose a machine learning approach to quantify (a) consistency specificity of colour-emotion associations (b) degree which they country-specific, on basis accuracy statistical classifier decoding term evaluated given trial ratings predicting...

Memories of war, terrorism, and natural disaster play a critical role in the construction group identity persistence conflict. Here, we argue that personal memory knowledge collective past become entwined only when public events have direct, forceful, prolonged impact on population. Support for this position comes from cross-national study which participants thought aloud as they dated mundane autobiographical events. We found Bosnians often mentioned their civil war Izmit Turks made...

Visuospatial bootstrapping is the name given to a phenomenon whereby performance on visually presented verbal serial-recall tasks better when stimuli are in spatial array rather than single location. However, display used has be familiar one. This implies communication between cognitive systems involved storing short-term memory for and visual information, alongside connections from knowledge held long-term memory. Bootstrapping robust, replicable that should incorporated theories of working...

Abstract As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact mood overall well‐being. However, there is a lack of empirical evidence provide informed guidance on colour choices, irrespective age group. To work towards we investigated whether associations between emotions observed younger individuals also apply older adults. We recruited 7393 participants, aged 16 88 years coming from 31 countries. Each participant associated 12...

Two experiments examined whether the age of acquisition (AoA) a concept influences speed at which native English speakers are able to name pictures using newly acquired second language (L2) vocabulary. In Experiment 1, participants were taught L2 words associated with pictures. 2 group same L1 translations. Following training both groups performed picture naming task in they asked words. Significant AoA effects observed only that faster representing early relative late concepts. The results...

It is considered that an individual's current self-concept plays a crucial role in guiding the retrieval of autobiographical memory. Using novel fluency paradigm, present research examined whether or not reverse also true, is, does memory influence description conceptual self? Specifically, this study effect prior reverie on subsequent stored self-concepts. Participants wrote personally relevant control topic (of no relevance to self), following which they had 60 seconds generate as many...

Traditionally, working memory is held to comprise separate subcomponents dedicated the temporary storage of visuospatial and verbal information. More recently, addition an episodic buffer has been proposed where information from multiple systems integrated. We report experiment designed investigate effects providing additional in a task. When to-be-remembered digits were arranged horizontal line, performance was no better than when presented single location. However, keyboard array,...

The question of how meaningful associations between verbal and spatial information might be utilized to facilitate working memory performance is potentially highly instructive for models function. present study explored separable processing capacities within specialized domains each contribute this, by examining the disruptive impacts simple concurrent tasks on young adults' recall visually presented digit sequences encountered either in a single location or "keypad" configuration....

The interaction between length and lexical status is one of the key findings used in support models reading aloud that postulate a serial process orthography-to-phonology translation (B. S. Weekes, 1997). However, proponents parallel argue this effect arises peripheral visual or articulatory processes. authors addressed possibility using special characteristics Serbian Japanese writing systems. Experiment 1 examined effects when participants were biased to interpret phonologically bivalent...

Abstract The effect of age acquisition (AoA) on word naming in Japanese was examined. Half the participants had words presented Kanji, and for other half same were Kana. There a main script with being read aloud faster when their Kana compared to Kanji transcription, AoA times earlier acquired stimuli. interaction between type also significant, larger These results are consistent hypothesis that size is influenced by nature mapping orthography phonology.

Humans have evolved a remarkable ability to remember visual shapes and use these representations generate motor activity (from Palaeolithic cave drawings through Jiahu symbols cursive handwriting). The term visual-motor memory (VMM) describes this psychological ability, which must conveyed an evolutionary advantage remains critically important humans (e.g. when learning write). Surprisingly, little empirical investigation of unique human exists--almost certainly because the technological...
