Do we know what we're simulating?:information loss on transferring unconscious perceptual simulation to conscious imagery

Perceptual simulations are unconscious and automatic, whereas perceptual imagery is conscious and deliberate, but it is unclear how easily one can transfer perceptual information from unconscious to conscious awareness. We investigated whether it is possible to be aware of what one is mentally representing; that is, whether it is possible to consciously examine the contents of a perceptual simulation without information being lost. Studies 1 and 2 found that people cannot accurately evaluate the perceptual content of a representation unless attention is explicitly drawn to each modality individually. In particular, when asked to consider sensory experience as a whole, modality-specific auditory, gustatory, and haptic information is neglected, and olfactory and visual information distorted. Moreover, information loss is greatest for perceptually complex, multimodal simulations. Study 3 examined if such information loss leads to behavioral consequences by examining performance during lexical decision, a task whose semantic effects emerge from automatic access to the full potential of unconscious perceptual simulation. Results showed that modality-specific perceptual strength consistently outperformed modality-general sensory experience ratings in predicting latency and accuracy, which confirms that the effects of Studies 1 and 2 are indeed due to information being lost in the transfer to conscious awareness. These findings suggest that people indeed have difficulty in transferring perceptual information from unconscious simulation to conscious imagery. People cannot be aware of the full contents of a perceptual simulation because the act of bringing it to awareness leads to systematic loss of information

Embodied Conceptual Combination

Conceptual combination research investigates the processes involved in creating new meaning from old referents. It is therefore essential that embodied theories of cognition are able to explain this constructive ability and predict the resultant behavior. However, by failing to take an embodied or grounded view of the conceptual system, existing theories of conceptual combination cannot account for the role of perceptual, motor, and affective information in conceptual combination. In the present paper, we propose the embodied conceptual combination (ECCo) model to address this oversight. In ECCo, conceptual combination is the result of the interaction of the linguistic and simulation systems, such that linguistic distributional information guides or facilitates the combination process, but the new concept is fundamentally a situated, simulated entity. So, for example, a cactus beetle is represented as a multimodal simulation that includes visual (e.g., the shiny appearance of a beetle) and haptic (e.g., the prickliness of the cactus) information, all situated in the broader location of a desert environment under a hot sun, and with (at least for some people) an element of creepy-crawly revulsion. The ECCo theory differentiates interpretations according to whether the constituent concepts are destructively, or non-destructively, combined in the situated simulation. We compare ECCo to other theories of conceptual combination, and discuss how it accounts for classic effects in the literature

Sensorimotor Norms: Perception and Action Strength norms for 40,000 words

Sensorimotor information plays a fundamental role in cognition. However, datasets of ratings of sensorimotor experience have generally been restricted to several hundred words, leading to limited linguistic coverage and reduced statistical power for more complex analyses. Here, we present modality-specific and effector-specific norms for 39,954 concepts across six sensory modalities (touch, hearing, smell, taste, vision, and interoception) and five action effectors (mouth/throat, hand/arm, foot/leg, head excluding mouth, and torso), which were gathered from 4,557 participants who completed a total of 32,456 surveys using Amazon's Mechanical Turk platform. The dataset therefore represents one of the largest set of semantic norms currently available. We describe the data collection procedures, provide summary descriptives of the data set, demonstrate the utility of the norms in predicting lexical decision times and accuracy, as well as offering new insights and outlining avenues for future research. Our findings will be of interest to researchers in embodied cognition, cognitive semantics, sensorimotor processing, and the psychology of language generally. The scale of this dataset will also facilitate computational modelling and big data approaches to the analysis of language and conceptual representations

Interoception:The forgotten modality in perceptual grounding of abstract and concrete concepts

Conceptual representations are perceptually grounded, but when investigating which perceptual modalities are involved, researchers have typically restricted their consideration to vision, touch, hearing, taste and smell. However, there is another major modality of perceptual information that is distinct from these traditional five senses; that is, interoception, or sensations inside the body. In this paper, we use megastudy data (modality-specific ratings of perceptual strength for over 32 000 words) to explore how interoceptive information contributes to the perceptual grounding of abstract and concrete concepts. We report how interoceptive strength captures a distinct form of perceptual experience across the abstract–concrete spectrum, but is markedly more important to abstract concepts (e.g. hungry, serenity) than to concrete concepts (e.g. capacity, rainy). In particular, interoception dominates emotion concepts, especially negative emotions relating to fear and sadness, moreso than other concepts of equivalent abstractness and valence. Finally, we examine whether interoceptive strength represents valuable information in conceptual content by investigating its role in concreteness effects in word recognition, and find that it enhances semantic facilitation over and above the traditional five sensory modalities. Overall, these findings suggest that interoception has comparable status to other modalities in contributing to the perceptual grounding of abstract and concrete concepts.

The effects of temperature on prosocial and antisocial behaviour: A review and meta-analysis

Research from the social sciences suggests an association between higher temperatures and increases in antisocial behaviours, including aggressive, violent, or sabotaging behaviours, and represents a heat-facilitates-aggression perspective. More recently, studies have shown that higher temperature experiences may also be linked to increases in prosocial behaviours, such as altruistic, sharing, or cooperative behaviours, representing a warmth-primes-prosociality view. However, across both literatures, there have been inconsistent findings and failures to replicate key theoretical predictions, leaving the status of temperature-behaviour links unclear. Here we review the literature and conduct meta-analyses of available empirical studies that have either prosocial (e.g., monetary reward, gift giving, helping behaviour) or antisocial (self-rewarding, retaliation, sabotaging behaviour) behavioural outcome variables, with temperature as an independent variable. In an omnibus multivariate analysis (total N = 4577) with 80 effect sizes, we found that there was no reliable effect of temperature on the behavioural outcomes measured. Further, we find little support for either the warmth-primes-prosociality view or the heat- facilitates-aggression view. There were no reliable effects if we consider separately the type of behavioural outcome (prosocial or antisocial), different types of temperature experience (haptic or ambient), or potential interactions with the experimental social context (positive, neutral or negative). We discuss how these findings affect the status of existing theoretical perspectives, and provide specific suggestions advancing research in this area

Alcohol advertising in sport and non-sport TV in Australia, during children’s viewing times

Objective: To Estimate the amount of alcohol advertising in sport vs. non-sport programming in Australian free-to-air TV and identify children’s viewing audience composition at different times of the day. Alcohol advertising and TV viewing audience data were purchased for free-to-air sport and non-sport TV in Australia for 2012. We counted alcohol advertisements in sport and non-sport TV in daytime (6am-8.29pm) and evening periods (8.30pm-11.59pm) and estimated viewing audiences for children and young adults (0–4 years, 5–13 years, 14–17 years, 18–29 years). During the daytime, most of the alcohol advertising (87%) was on sport TV. In the evening, most alcohol advertising (86%) was in non-sport TV. There was little difference in the mean number of children (0–17 years) viewing TV in the evening (N = 273,989), compared with the daytime (N = 235,233). In programs containing alcohol advertising, sport TV had a greater mean number of alcohol adverts per hour (mean 1.74, SD = 1.1) than non-sport TV (mean 1.35, SD = .94). Alcohol advertising during the daytime, when large numbers of children are watching TV, is predominantly in free-to-air sport TV. By permitting day-time advertising in sport programs and in any programs from 8.30pm when many children are still watching TV, current regulations are not protecting children from exposure to alcohol advertising

Replication of “Experiencing physical warmth promotes interpersonal warmth” by Williams & Bargh (2008)

We report the results of three high-powered, independent replications of Study 2 from Williams and Bargh (2008). Participants evaluated hot or cold instant therapeutic packs before choosing a reward for participation that was framed as a prosocial (i.e., treat for a friend) or self-interested reward (i.e., treat for the self). Williams and Bargh predicted that evaluating the hot pack would lead to a higher probability of making a prosocial choice compared to evaluating the cold pack. We did not replicate the effect in any individual laboratory or when considering the results of the three replications together (total N = 861). We conclude that there is no evidence that brief exposure to warm therapeutic packs induces greater prosocial responding than exposure to cold therapeutic packs

A Registered Report Survey of Open Research Practices in Psychology Departments in the UK and Ireland

Open research practices seek to enhance the transparency and reproducibility of research. While there is evidence of increased uptake in these practices, such as study preregistration and open data, facilitated by new infrastructure and policies, little research has assessed general uptake of such practices across psychology university researchers. The current study estimates psychologists' level of engagement in open research practices across universities in the United Kingdom and Ireland, while also assessing possible explanatory factors that may impact their engagement. Data were collected from 602 psychology researchers in the United Kingdom and Ireland on the extent to which they have implemented various practices (e.g., use of preprints, preregistration, open data, open materials). Here we present the summarized descriptive results, as well as considering differences between various categories of researcher (e.g., career stage, subdiscipline, methodology), and examining the relationship between researcher's practices and their self-reported capability, opportunity, and motivation (COM-B) to engage in open research practices. Results show that while there is considerable variability in engagement of open research practices, differences across career stage and subdiscipline of psychology are small by comparison. We observed consistent differences according to respondent's research methodology and based on the presence of institutional support for open research. COM-B dimensions were collectively significant predictors of engagement in open research, with automatic motivation emerging as a consistently strong predictor. We discuss these findings, outline some of the challenges experienced in this study, and offer suggestions and recommendations for future research. Estimating the prevalence of responsible research practices is important to assess sustained behaviour change in research reform, tailor educational training initiatives, and to understand potential factors that might impact engagement

The Effect of a Food Addiction Explanation Model for Weight Control and Obesity on Weight Stigma

There is increasing scientific and public support for the notion that some foods may be addictive, and that poor weight control and obesity may, for some people, stem from having a food addiction. However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of 'fat people', and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F(4,525) = 7.675, p = 0.006; and F(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of 'fat people' stigma measure (F(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma (F(5,684) = 0.217, p = 0.81). Participants receiving the diet and exercise explanation had greater dislike of 'fat people' than those in the FAM explanation and control group (p values 0.05). The FAM explanation for weight control and obesity did not increase weight stigma and resulted in lower stigma than the diet and exercise explanation that attributes obesity to personal control. The results highlight the importance of health messaging about the causes of obesity and the need for communications that do not exacerbate weight stigma
