How does metaphorical language affect individuals’ aesthetic perception in modern poetry: In the life span view
subject: Beauty perception Metaphoricity Familiarity Imageability
description: This study examined the relationship between the degree of metaphoricity and beauty perception as well as between cognitive load and beauty perception, by controlling for other possibly confounding variables such as familiarity and imageability. While previous research has shown that the variables of metaphoricity, familiarity and imageability influence beauty perception, no study investigate how the degree of metaphoricity and cognitive load influence beauty perception in poetic sentences reading. Therefore, this study aimed to bridge this gap. Beauty rating scale and keypress experiment were conducted, involving 22 young adults and 18 elderly adults. Because of the collinearity among metaphoricity, familiarity and iamgeability, a new variable called interpretation of metaphors was used to explain the hypotheses in the present study. Rather than cognitive load, interpretability was the predictor of beauty perception in poetry sentences reading. Young adults’ beauty perception achieved to the highest point at novel metaphors, while elderly adults considered dead metaphors as the most beautiful stimuli. This study suggests that poetic sentences are generally perceived as more beautiful when its degree of interpretability is lower in young adults rather than elderly adults. These findings provide an initial implication for future longitudinal or neuroaesthetic studies to further the understanding between metaphorical language and beauty perception.

Besides, this study were preregistered in ‘AsPredicted’ website, and the number was 11034. Participants. The participants were 22 young adults between the ages of 18 and 30, and 20 elderly adults between the ages of 55-75. They were recruited from SONA systems, social media (e.g., Facebook advert). All young participants have not suffered from any learning disability (i.e., dyslexia) and they were native English speakers. However, two elderly participants confirmed that they had a history of dyslexia, so they were excluded. Finally, there were 22 young adults with a mean age of 21.64 years (SD=3.05) and 18 elderly adults with a mean age of 63.22 years (SD=6.07) have participated. Participants were required to give informed consent via an online consent form before completing the online survey, and they would fill in a paper version consent form before the keypress experiment. All participant would receive four pounds after finishing all experiments. Materials. Stimuli. A bank of 92 stimuli, was generated by a previous student who was previously supervised by Dr Francesca Citron. Partially sentences are excerpted from modern poetry. The remaining sentences were created by this student, inspired by other poetic works. Creating novel sentences was to decrease the deviation caused by participants being familiar with some stimuli. All stimuli were divided into five categories, and the degree of metaphoricity of these categories was increasing. The first one is the literal expression which has concrete and pragmatic meaning and it usually equal to its literal meaning. It is not part of the metaphorical language. The following category is dead metaphors – a kind of metaphor that lose its imaginative space because of frequent use (Punter, 2007). The third one is the conventional metaphor that is commonly used in everyday life, and it is highly related to the specific cultu…

How the correlation of Istagram tweets readability and brand hedoism affect audiecne engagment
subject: Readability, Brand hedonism, readbility formula, audience engagment
description: Social media marketing is increasing in importance and more and more brands are embracing social media to increase their brand reach and communicate with their audience. However, there is still little empirical research on how brand message features affect consumer engagement. This study focuses on the impact of readability as an influence on consumer engagement while also noting that the effect of hedonic value of a brand may potentially moderate the level of audience engagement. An experiment based on a sample of 20 of the 100 brands covered by Forbes Media was conducted for this study. In total, a sample of 400 Instagram tweets were collected and analysed for their text readability and audience engagement. Still, the results did not indicate a significant interaction between readability and engagement. A careful analysis of the difficulties and shortcomings encountered in this experiment provides some insights for any subsequent research on the readability of short-form communication by brands.
creator: Jiehong Wu
source: Research Question & Hypotheses The research question for this study is: can the readability of tweets influence the level of audience engagement? As readability increases the perception associated with processing fluency (Rennekamp, 2012), the ability to process information fluently makes the target message more appealing to the audience, and visual fluency in processing information can also increase people's perception of the processing target (Novemsky et al., 2007). Language that can be processed fluently also enhances consumer perceptions (Lee & Aaker, 2004; Lee & Labroo, 2004). Thus, for most brands with low levels of hedonism, higher tweet readability means higher processing fluency which can reduce audience metacognitive difficulties and thus increase tweet engagement levels. At the same time, for products with high hedonic demand, lower familiarity and uniqueness may provide consumers with greater signals of value, with metacognitive difficulties increasing the appeal of the product by making it appear unique or unusual. More easily processed messages reduce the appeal of the product, possibly because they appear too familiar and therefore less consistent with the perception of uniqueness (Pocheptsova, Labroo, 2004；Pocheptsova, Labroo, and Dhar 2010). It is therefore hypothesised that text features associated with greater readability will be positively associated with consumer engagement with the message. However, given the presence of brand hedonistic features, it can be argued that low readability of messages may increase consumer engagement in brand tweets with higher levels of hedonism instead. Data collection for the experiment From the above, whether the readability of the tweet text and the level of brand hedonism of the brand to which the tweet belongs combine to influence consumer engagement with the brand's social tweets must be determined. Instagram was chosen because it is one of the world's most popular social networks, with around one billion a…

Implicit Hand Representations in Typical Ageing and in Parkinson's Disease
subject: LUSTRE, aquisition form, wordpress
description: Having an internal representation of one’s own body is important for many interactions with the environment, and in making decisions about what actions we are capable of performing. However, even in healthy adults, these representations are known to be distorted. In the hand specifically, individuals are likely to underestimate the length of all fingers, but overestimate the distance between each adjacent pair of knuckles. Both healthy ageing and Parkinson’s Disease (PD) include apsects which are known to further distort body representations, including, but not limited to, diminished tactile sensitivity and impaired action capabilities. This study was designed to investigate the accuracy of hand representations in typical ageing and in PD. Fourteen participants with mild to moderate PD, 17 healthy age-matched controls and 20 younger controls made estimates about the location of hand landmarks when the hand was hidden from view. Estimations were compared with actual hand size. Older controls and individuals with PD both demonstrated more accurate representations of thumb length, and of distance between the index and middle knuckles than younger controls, with older controls also showing differences in their perception of distance between thumb and index knuckles. However, no differences were found between the PD group and older controls, suggesting that the formation of body representations is an ability which is preserved in PD. Possible explanations for, and implications of these results are discussed.

source: Participants To determine the number of participants necessary, a priori power analysis was conducted in G*Power (Faul et al., 2009), using α= 0.05, β= .08 and effect size = 0.32. This effect size was calculated from Longo (2014), which employed a similar methodology. The analysis determined that 10 participants in each condition were required to yield sufficient power. Previous studies using this methodology have included sample sizes ranging from 12-22 participants (Longo & Haggard, 2010, 2012; Peviani & Bottani, 2020). The intended sample size, therefore, was 20 participants per condition. Due to the time constraints of the study, this number was not reached for all conditions, but all conditions included more than the 10 participants needed as suggested by the priori analysis. 20 younger controls were tested (15 female). Their ages ranged from 19 to 30 (M = 22.40 yrs, SD = 2.21 yrs). 17 were right-handed, and 3 were left-handed, with handedness ranging from -89.5 to 100 (M = 64.52, SD = 61.84) on the Edinburgh Handedness Inventory (EHI; Oldfield, 1971). 17 healthy older controls were tested (11 female). Their ages ranged from 52 to 79 (M = 66.12 yrs, SD = 9.16 yrs). 14 were right-handed, and 3 were left-handed, with handedness scores ranging from -100 to 100 (M = 65.29, SD = 77.31). 14 individuals with PD were tested (4 female). Their ages ranged from 54 to 78 (M = 65.93 yrs, SD = 8.43 yrs). All PD participants were right-handed, with handedness scores ranging from 33.5 to 100 (M = 88.31, SD = 21.20). There was no significant difference between the ages of the participants in the typically ageing and the PD condition, t(29) = 0.06, p = .95. For the PD participants, the most recent onset of PD was 3 years ago, with the longest diagnosis of 20 years (M = 7.75 yrs, SD = 4.81 yrs). All presented with a Hoehn and Yahr Stage of 3 or below. This indicated that all participants were physically independent. All participants had been prescribed antiparkinsonian medication…

Infant Gesture and Parent Knowledge of Development
subject: None
description: Background: Before children can communicate verbally, they use gesture to tell us what they want. Our understanding of the importance of gesture in language development has expanded greatly over the past few decades. Furthermore, the methods used to measure gesture and language development have also progressed. Gesture and language assessment rely heavily on parent reports. It has been suggested that what parents know about development has also consequences for their child’s developmental outcomes. Aims: To validate the gesture section of the UK-CDI Words and Gestures (Alcock, Meints, & Rowland, 2017). And to explore parent knowledge of language and gesture milestones Methods & Procedure: Twenty-seven children and their parents participated in the first experiment. The parents completed the UK-CDI W&G and the children participated in an in- person gesture validation task. Thirty parents with a child 8-18 months participated in the second experiment. They completed the UK-CDI W&G as well as our new parent knowledge questionnaire. Results: In Experiment one, children’s score from the gesture task correlated significantly with parent-reported scores on the UK-CDI W&G. In experiment two, parents were more accurate at ordering and estimating the age of language milestones than they were gesture milestones. Conclusions: The findings for experiment one provides more support and confidence for the UK-CDI W&G as a language assessment tool. This will provide and benefit researchers and clinicians with a standardised tool and method for assessing language norms and delays. The findings for experiment two inform us that parents are not that knowledgeable within the developmental domain of gesture. This provides us with information on where parents need to be educated to benefit the developmental outcomes of their children.

source: Experiment 1 Method In this experiment we attempted to validate the gesture section of the UK-CDI Words and Gestures questionnaire through responses to the questionnaire and with an in-person gesture task procedure. Participants Twenty-seven children and their parent participated in this study. Participants included 10 girls and 17 boys between eight and eighteen months (M= 12.5 months, SD= 2.3 months) who were recruited from the Lancaster University Babylab and through social media (e.g. Facebook). The parents who participated in this study were 26 mothers and one father. To be eligible for this study all participants had to be native British English speakers. All participants were self-selected and received a children’s book for participant payment. Apparatus and Materials UK-CDI Words and Gestures The UK-CDI Words and Gestures (Alcock et al. 2013) is a parent-report questionnaire used to assess the language development of children aged eight to 18 months old. This questionnaire offers a checklist of words from several different categories (e.g., animals, toys, household items), with a total of 395 words. Parents are asked to indicate whether their child can say and understand, just understand, or does not know a word. The child obtains a score for total comprehension (sum of the words they understand) and a total score for production (sum of the words they say and understand). There is also a gesture section consisting of 57 gestures. The gesture section is divided into subsections (e.g., first communicative gestures, games, actions, pretending to be a parent, and imitating other adult actions). In the First Communicative Gesture section, parents are asked to indicate whether their child does a gesture often (two points), sometimes (one point), or not yet (zero points). For the remaining sections parents are asked to tick yes or no if their child does a gesture. A total gesture score is calculated by taking 0.5* the First Communicative Gesture section score and i…

Infants' Awareness of Number: Innate Ability or Perceptual Bias?
subject: Addition, subtraction, Number, Object Tracking, object files, Infant perception
description: In order to identify the origin of our understanding of numerosity and arithmetic abilities, it is essential that such abilities are measured in infants. In Wynn’s (1992) study, a case was made for an innate ability to perform arithmetic operation on small number sets as it was demonstrated that infants would look longer at displays that violated their expectations of number. However, research in the years following this seminal study cast doubt on this interpretation of infants’ behaviour. Other research has suggested that perceptual biases are at play, rather than infants possessing a symbolic understanding of number. To address the contrasting finding in this area of developmental research, this study set out to analyse preexisting data to investigate the factors that influence infants’ abilities to track objects over occlusion and to identify the most appropriate level of interpretation of this ability The present study recruited a sample of 32 infants across two experiments. Adapting the methodology from Wynn (1992), Experiment 1 measured looking time when an object was revealed to be missing from the display, violating infants’ expectation of presence. Experiment 2 measured looking time when an object was revealed to be in the incorrect position on the stage, violating infants’ expectation of position. It was found that infants violation trial had a significant effect on looking time and whether the object missing was the first or last to be placed had a significant effect on looking time in violation of presence conditions
creator: Jessica Sparks
source: Participants: In this study, participants were 32 infants aged 5- to 7-months, (M = 188.38 days, SD = 10.51, range = 175 – 218). Infants were 15 males and 17 females. 16 participants were used in each experiment. In Experiment 1, participants were 7 males and 9. In Experiment 2, participants were 8 males and 8 females. Participants in each experiment were matched based on age. Apparatus & Stimuli: The experiment took place in a dimly lit test room, with displays presented on a grey stage measuring 64cm wide by 40cm high and 31cm deep. An 8.5cm high black screen located 31.5cm behind the front of the stage was used to occlude the display by being rotated upwards. The display also consisted of a 30cm rotating platform that allowed different configurations of objects to be rotated rapidly. The objects used in this study were two 12.5cm high by 9.5cm wide toy hedgehogs that squeaked when squeezed. These toys were magnetic at the bottom. Procedure: Infants were sat in either a high seat or on a caregiver’s lap, 60cm from the front edge of the stage. In cases where infants were sat on a caregiver’s lap, the caregiver’s eyes were above the stage as to avoid them seeing the display and possibly influencing the infant’s behaviour. After gaze calibration to ensure the accuracy of eye-tracking measures, the procedure closely followed that of Wynn (1992) and Bremner et al (2017). Three pre-test (baseline) trials were presented initially. These resulted in the correct outcome of the operation as well as the two incorrect outcomes in counterbalanced order. The screen was lowered to reveal either one or two toys, depending on the trial, and the observer recorded where the infant looked on the stage. In terms of the location of the toys in trials, when one was presented, it was placed 7.5cm to the right of the stage’s centre. When two toys were presented, the second toy was placed 7.5cm to the left of the stage’s centre. Pre-test trials continued until the infant accumulated at lea…

Influence of an autobiographical memory recollection on moral decision making.
subject: The language effect emotional decision making guilt empathy pro-social behaviour
description: Research shows that emotional states are involved in moral reasoning and may affect people’s decision-making processes (Achar, So, Agrawal, & Duhachek, 2016). However, in recent research emotional states were shown to be easily influenced by such factors as the language type. It was found that a stimulus presented in the native language was perceived more emotionally when compared to stimuli presented in the second language (Pavlenko, 2005). This difference in emotionality was called the language effect (Puntoni, S., Langhe, & Van Osselaer, 2009). The relationship between used language (native vs. second) and emotionality level is important as it may provide potential applications in promoting beneficial decision making and consequent behaviour. Many advertising campaigns already target emotions (i.e. empathy, guilt, regret) in order to persuade people to act by their request (Lee, Andrade, Palmer, 2013). Thus the focus of this research was to analyse the relationship between emotional language processing (native vs. second language) targeting guilt, empathy levels and how they influence the consequent behaviour (i.e. helping). A multicultural sample of 126 bilingual adults, who all speak English, as a second language, completed an online questionnaire, assessing self-reported guilt, pro-social behaviour inclination, empathy and pro-social behaviour. Results showed that no significant differences were found between two language groups, indicating the lack of language effect in the present sample. Also, the results showed that high levels of self-reported guilt were significantly and positively associated with high levels of pro-social inclination and pro-social behaviour. Empathy was shown to have the same association – high levels of empathy being associated with high levels of pro-social inclination and pro-social behaviour. Lastly, further analysis found selfreported guilt as a predictor of pro-social behaviour and pro-social behaviour inclination. Overall, this …

source: Participants Participants of this study were adults, who spoke English as a second language (N= 126, 58 males, 68 females) and ranged in age from 18 to 46. Originally there were 138 participants, but 12 were excluded from further analysis due to being the native speakers of the English language and therefore not fitting the core requirement – speaking English as a second language. Also 10 participants wrote the memory in English instead of their native language, so they were diverted to the second language condition before proceeding with the analysis. The whole sample of participants was very diverse, which consisted of 25 different nationalities and 24 different native languages (see Appendix D), the top four languages being - Lithuanian (40), Spanish (14), German (13) and Polish (13). All participants signed an online consent form and answered questions about their nationality, native language, country of residence, and English language proficiency before proceeding with the questionnaire. Materials Self-reported guilt Self-reported guilt was measured by asking participants to first – recall and describe a memory in either their native or second language (i.e. English) and then to evaluate how bad they feel about their recalled actions, how guilty they feel about those actions and how much they regret them (Nelissen, 2012). All of the three questions testing self-reported guilt were assessed by 6-point forced choice Likert scale from 1 (‘Very much’) to 6 (‘Not at all’). Before the start of analyses, the scale was reverse scored from 1 (‘Not at all’) to 6 (‘Very much’) to ensure consistency with other measures. Pro-social behaviour The pro-social behaviour was measured by asking participants, how many additional questions they would be willing to answer after completing the survey. Participants were informed that they are almost done with the survey. However, it was stated, that it would be a great help to the researchers if participants could answer some addition…

Inner Speech and Grit: Do Positive Inner Speech and Evaluative Inner Speech Lead to Grit Behaviour
subject: Inner speech, grit, articulatory suppression
description: Grit, defined as perseverance and passion for long-term goals, is a reliable predictor of success metrics, surpassing even IQ. While the exploration of grit has been conducted extensively, studies on the mechanisms of grit are still lacking. Inner speech, the silent production of words in one’s mind, plays a pivotal role in managing thoughts. This includes cognitive reframing, which is essential for enhancing perseverance. Theoretically, inner speech can predict grit. This study, employing a survey and experimental design, aims to investigate whether positive inner speech and evaluative inner speech can predict grit behaviour. The data for this study (n=56) were collected in two ways: (1) using the grit scale and inner speech VISQ-R via a Qualtrics survey, and (2) using participants’ task retention decisions and a qualitative classification approach. The data were analysed using R Studio. The survey data were analysed via a linear model, while the qualitative data were analysed using a generalised linear mixed-effects model. The survey results showed that only evaluative inner speech can positively predict grit. However, there were imbalanced results regarding the participants’ task retention decisions. Collectively, these findings underscore that grit can be predicted by evaluative inner speech. This prompts further research to explore its multifaceted role in shaping grit across various domains.
creator: Huzaifah Adam
source: This study applied a mixed-method and correlational research design that aims to examine whether evaluative inner speech and positive inner speech lead to grit behaviour. The data for this study were collected using two methods: (1) questionnaires through a Qualtrics survey, and (2) an experimental task where the participants were asked to complete two sets of puzzles under different conditions (baseline and with articulatory suppression) and provide their retrospective experience after each puzzle task. Participants’ task retention decisions (decision to quit) were also recorded in the study. Three different analyses were applied in the research. For the first analysis, the positive inner speech and evaluative inner speech scores from VISQ-R acted as the predictors, and grit from the Short Grit Scale as the outcome. For the second analysis, the participant’s grit score acted as the predictor, and the participant’s task retention decision acted as the outcome. Lastly, the third analyses the types of inner speech based on the participant’s retrospective experience (positive inner speech and evaluative inner speech) acted as the predictors, and the participant’s decision to quit or not to quit was the output. In this study, the participants were students from Lancaster University, ranging from undergraduate degree students to master’s degree students and doctorate students. Participants were recruited using social networks, direct emails, and posters around the campus and/or on social media. The session took approximately 30 minutes for the data collection process, including the briefing, and each participant was reimbursed with five GBP for participating. Ethical approval for this study was submitted and approved by the ethics committees at Lancaster University. The number of participants involved in the study was 56 people in total.

Inner Speech and Its Role in Purchasing Decision-Making Process: Analysis of Within-Subjects Experiment and Questionnaires
subject: Inner speech, memory, decision-making, purchasing behaviour.
description: Inner speech is a cognitive function related to language processes. Based on its functions reflecting information processing and memorising, it may link to the purchasing process, which includes searching and evaluating product information. Inner speech may also help people think and imagine using the product in the future during their purchasing process. This study discussed and investigated the role of inner speech in the purchasing process and how it might affect the decision-making time. This study also mentioned how inner speech may be identified and suppressed. Participants’ data was collected through experiments and several questionnaires. The findings indicated that inner speech might help people in Information Search and Alternative evaluation and affect decision time. The findings also suggested what people may consider and how they use inner speech. By uncovering the potential relationship between the purchasing process and inner speech, this research provided valuable information for marketing and psychology research fields. It gave companies some suggestions for practical use, reflecting how people may use inner speech during the purchasing process.

Interacting in a Virtual Environment, the role of visual perception, the human hand and the recognition of rescaling.
subject: Visual Perception Rescaling effects Virtual Reality Hand-size Constancy Body size effects.
description: A common assumption from perception research is that we can estimate the size of the environment by using our own hand as a perceptual metric by comparing the size of our hand to the environment. Further research aimed to explore this effect by manipulating the size of the hand to see if it could accurately estimate the size of objects and found that even when the hand was magnified or minimized people perceived their hand to stay around the same size. The effect that the hand is perceived as a constant size is called the hand-size constancy effect and the current research has aimed to expand on previous research by examining if hand-size constancy still occurs even when hand size increases whilst in the presence of the participant. This research was done using a new method which eliminates more demand characteristics than previous hand-size constancy research. Participants took part in a virtual scenario using virtual reality in which each time a participant attempted the task, their hand or non-corporeal hand gradually increased in size, until a total of 38% size increase. Results from this research found that participants did recognise their hand size increase in the non-corporeal condition and did not notice hand size change in the real hand condition. These results support previous research by finding that hand size constancy can still occur even when eliminating demand characteristics that may have occurred in previous research using a more discrete method.

Participants were mainly recruited from a major university in the North West of England using posters on the university campus and online advertisements. Participants received £5 in return for their participation. Materials The current research used the Oculus Rift with leap motion to detect hand movement. The experiment was created using the Unity game engine software to create a programme called the virtual bowling alley.
