Judging a Book by its Cover: The Influence of Implicit Self‐Theories on Brand User Perceptions

Do people judge others based on the brands they use? Prior research finds evidence to this effect, yet we argue this phenomenon is far from universal. Drawing on research on implicit self‐theories, we find that only entity (but not incremental) theorists are prone to judging people based on their brand use (Studies 1 and 2). We show that entity theorists infer that people use brands to signal who they are to others, thereby forming perceptions of these people based on the personality of the brands they use, but incremental theorists are reluctant to make inferences about brand users’ signaling motives (Studies 3, 4, and 5). When tendencies to make signaling inferences are reduced, entity theorists no longer judge people based on their brand use (Studies 3 and 4). Furthermore, even incremental theorists judge people based on their brand use when given the information that their brand use is not driven by situational forces, but is potentially driven by a signaling motivation (Study 5).     

Context and Perceptual Salience Influence the Formation of Novel Stereotypes via Cumulative Cultural Evolution

We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions—color, movement, and shape—thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that described it (e.g., arrogant, caring, confident). Participants were given training on the alien‐attribute assignments and were then tested on their memory for these. The alien‐attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype‐like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., 2014 which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information.     

Cognitive neuroscience of aging: contributions of functional neuroimaging

By revealing how brain activity during cognitive performance changes as a function of aging, studies using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are contributing to the development of a new discipline of Cognitive Neuroscience of Aging. This article reviews functional neuroimaging studies of cognitive aging in the domains of visual perception, episodic memory encoding and semantic memory retrieval, episodic memory retrieval, implicit memory, and working memory. The most consistent finding of these studies was that brain activity tends to be less lateralized in older adults than in younger adults. This finding is conceptualized in terms of a model called Hemispheric Asymmetry Reduction in Old Adults (HAROLD). According to a compensation hypothesis, bihemispheric involvement could help counteract age-related neurocognitive decline, whereas, according to a dedifferentiation hypothesis, it reflects a difficulty in recruiting specialized neural mechanisms.     

Emotional stimuli facilitate time perception in children with attention‐deficit/hyperactivity disorder

The aim of this study was to compare the effect of different emotional stimuli (neutral, positive, and negative) on time perception in children with attention‐deficit/hyperactivity disorder (ADHD) and normal children in dual‐task form. Five hundred and ninety‐nine students from primary schools were randomly selected. The Conner's Teacher Rating Scale (CTRS) questionnaire was completed by teachers. A total of 100 children with a score above the cut‐off point for the CTRS were further assessed using the Child Symptom Inventory‐4 (CSI‐4). A total of 34 children with ADHD and 31 controls completed an emotional time discrimination task in two blocks of 1000 and 2000 ms duration. Children were asked to compare three image groups: neutral with neutral, neutral with positive, and neutral with negative images. Children with ADHD had significantly better performance in the emotional time discrimination task across all conditions when compared with controls: On average, discrimination thresholds were approximately 35 ms shorter for the children with ADHD. Our results indicate that children with ADHD have higher sensitivity to time relative to controls in a situation in which they must distribute resources between temporal and emotional processing. On the basis of the interference effect and the working memory capacity hypothesis, this dividing of attention causes a decrease of time accuracy in normal children.     

认知神经科学关于表象的研究

表象是不是除命题表征之外的一种独立的表征问题一直是心理学上争论不休的话题。争论的焦点主要在视觉表象与视知觉的关系上,有些研究发现视觉表象能够激活视觉系统,甚至能够激活较早的视觉皮质(如V1区),而且视知觉的选择性障碍也会导致相应的视觉表象障碍,但另外的研究却没有发现视觉表象能够激活较早的视觉皮质,而且发现视觉表象与视知觉存在双重分离。文章最后讨论了视觉表象研究中存在的一些问题。     

FREE WILL AND LUCK

I present an account of how agents can know what they are doing when they intentionally execute object-oriented actions. When an agent executes an object-oriented intentional action, she uses perception in such a way that it can fulfil a justificatory role for her knowledge of her own action and it can fulfil this justificatory role without being inferentially linked to the cognitive states that it justifies. I argue for this proposal by meeting two challenges: in an agent's knowledge of her action perception can only play an enabling role (and no justificatory role) for the agent's knowledge and if perception has a justificatory role, then the agent's knowledge must be inferential.     

A cross-cultural study of infant temperament: Predicting preschool effortful control in the United States of America and Russia

Effortful control (EC) has been conceptualized as a dimension of temperament related to self-regulation and associated with the development of executive attention skills. Research has focused on documenting the development of EC, but there has been little systematic study of its precursors. The present study was designed to examine infant temperament characteristics as potential predictors of EC in the toddler/preschool period across two countries: Russia and the USA. Specifically, contributions of negative emotionality (NE), positive affectivity/surgency (PAS), and regulatory capacity/orienting (RCO) measured in the first year of life were expected to explain EC in the preschool period. For the US sample, toddler NE, infant PAS and RCO explained significant amounts of EC variance, whereas infant RCO was the single significant predictor of later EC in the Russian sample. Analyses with the combined sample provided an opportunity to evaluate temperament-by-culture interactions, one of which (PAS×Culture) reached statistical significance. Follow-up analyses indicated that higher levels of infant PAS were related to higher EC scores for US children only, whereas for the Russian youth preschool EC did not vary as a function of infant PAS. Results of this study support the importance of early appearing regulation in contributing to the development of EC and illustrate the value of cross-cultural longitudinal research.     

Love and Benevolence in Hutcheson's and Hume's Theories of the Passions

In this paper I consider two related issues raised by Aristotle's treatment of hearing and sounds. The first concerns the kinds of changes Aristotle takes to occur, in both perceptual medium and sense organs, when a perceiver hears a sounding object. The second issue concerns Aristotle's views on the nature and location of the proper objects of auditory perception. I argue that Aristotle's views on these topics are not what they have sometimes been taken to be, and that when rightly understood they compare favourably in many respects with leading contemporary accounts.     

Specifying the human body configuration

Three experiments investigated the specific spatial relations that define the human body configuration. In Experiment 1, participants searched for scrambled bodies amongst normal distractors. In Experiments 2 and 3 participants were asked to identify whether single body images (upright or inverted) were scrambled or normal. Scrambled bodies had head or limbs displaced to either symmetrical or asymmetrical positions. Experiment 1 showed that asymmetrical violations are recognized faster than symmetrical violations. All three experiments revealed that when the number of structural violations is held constant, head violations are recognized faster than limb violations. Experiment 3 also showed a greater inversion effect for scrambled bodies that maintained head on top and vertical symmetry, providing evidence that these are key spatial relations in the human body configuration. Overall, the results supported our hypothesis that the human body configuration is defined primarily by a head at the apex of a vertically symmetrical body.     

Temporal processing within and across senses

This special issue on temporal processing within and across senses was the outcome of a two-day workshop that took place in Tübingen, Germany. The aim of the workshop and this special issue was to advance our knowledge on timing and the senses and to bring together two lines of research that have not yet interacted, those of synchrony and duration perception.
