识解水平对跨期选择和风险选择的影响

通过考察识解水平启动对跨期选择和风险选择的影响, 探究两类选择对时间或风险心理加工的相似性。结果发现, 无论以思维诱导为识解水平的启动条件(实验1), 还是以视觉加工为识解水平的启动条件(实验2), 受高识解水平启动的被试对延迟选项和风险选项的主观值判断都要大于受低识解水平启动的被试, 说明跨期选择中的延迟时间和风险选择中的概率具有相似的表征, 而识解水平思维定势是通过影响金额和时间(或概率)的相对权重起作用。即由于高识解水平下的金额权重高于低识解水平, 时间(或概率)权重低于低识解水平, 从而使被试在高识解水平下更愿意等待或冒险。     

The bilingual effects of linguistic distances on episodic memory and verbal fluency

The impact of linguistic distance or the relatedness between two languages, on bilinguals’ episodic memory performance and verbal fluency is an understudied area. Thus, the purpose of this study was to determine if differences in linguistic distances have differential effects on these abilities. Measures of episodic recognition, categorical fluency, and global cognitive functioning were also considered in the analyses. Two matched samples with participants living and educated in Sweden were drawn from the Betula Prospective Cohort Study. Results showed that bilinguals who speak linguistically similar languages (Swedish and English), performed significantly better than monolinguals on both episodic memory recall and letter fluency, while bilinguals who speak two languages that are more distant (Swedish and Finnish), showed no advantages compared to their monolingual counterparts. For both tasks, however, a linear trend was observed indicative of better performance for the Swedish-English group compared to the Finnish-Swedish group, and for the Swedish-Finnish group compared to the monolinguals group. As expected, no differences between groups were found in any of the other cognitive tasks. Overall, results suggest that the impact of linguistic distances should be explored in more detail in the future.     

Serial murderers' spatial decisions: factors that influence crime location choice

The outcome of German serial murderer spatial decision making was measured as the straight‐line distance (km) between murderer home locations and each crime location (i.e. body recovery location). Geographic and series development data, as well as information on age, intelligence, motive, marital status, employment status, and mode of transportation of 53 German serial murderers was collected from police and prosecution service files and judicial verdict records. Potential effects of the aforementioned factors on spatial decisions were assessed. Results showed that 63% of the murderers lived within 10 km of their crime locations. Home‐to‐crime distance was negatively correlated with murderer age and positively correlated with murderer IQ score. Results also showed that the mode of transportation used by murderers had an effect on their spatial decisions. Results are discussed in terms of understanding serial murderer spatial decision‐making and implications for police investigations. Copyright © 2005 John Wiley & Sons, Ltd.     

Do object-category selective regions in the ventral visual stream represent perceived distance information?

It is well established that scenes and objects elicit a highly selective response in specific brain regions in the ventral visual cortex. An inherent difference between these categories that has not been explored yet is their perceived distance from the observer (i.e. scenes are distal whereas objects are proximal). The current study aimed to test the extent to which scene and object selective areas are sensitive to perceived distance information independently from their category-selectivity and retinotopic location. We conducted two studies that used a distance illusion (i.e., the Ponzo lines) and showed that scene regions (the parahippocampal place area, PPA, and transverse occipital sulcus, TOS) are biased toward perceived distal stimuli, whereas the lateral occipital (LO) object region is biased toward perceived proximal stimuli. These results suggest that the ventral visual cortex plays a role in representing distance information, extending recent findings on the sensitivity of these regions to location information. More broadly, our findings imply that distance information is inherent to object recognition.     

Mother-Infant Interaction Kinect Analysis (MIIKA): An automatic kinematic-based methodology for the investigation of interpersonal distance during early exchanges

Interpersonal distance is a core aspect of mother-child interaction. While conventional measures based on human coders do not fully capture the dynamics of this feature, computational methods provide automatic measures which can detect even small changes and more accurate estimates both spatially and temporally. Using RGB-D sensors (Microsoft Kinect V2), the present study describes a setup to automatically examine interpersonal distance during mother-child interactions, termed Mother-Infant Interaction Kinect Analysis (MIIKA). First, the laboratory setting and the data extraction method are described. By using an ad-hoc algorithm for kinematic data extraction, MIIKA returns three metrics: barycenter position (distance and velocity of approach and separation), movements (number of small, medium and large approaches and separations) and contributions (proportional contributions of mother and child to approaches and separations). Secondly, preliminary MIIKA metrics are described for a non-clinical mother-child dyad as an exemplification of the protocol. As interpersonal distance can be affected by contingent situations, we detected mother-infant full skeleton during three interactional contexts characterized by different kinds of dyadic exchanges: a free play session, a task-oriented activity and an emotionally arousing condition. Results highlighted similarities and differences between the three interactional contexts. MIIKA appears to be a promising setup to automatically examine interpersonal distance in early mother-child interactions.     

A normative perspective on the linguistic intergroup bias: How intragroup approval of ingroup members who use the linguistic intergroup bias perpetuates explicit intergroup bias

The present research examined from a normative perspective how intragroup normative processes regulate the consequences of the linguistic intergroup bias (LIB). Results of three studies supported our hypothesis that intragroup approval of an ingroup member who uses the LIB plays a key role in perpetuating pro-ingroup bias. In Study 1, ingroup members who used pro-ingroup (vs. pro-outgroup) LIB elicited more intragroup approval and this effect was mediated by the perception of the speaker as being biased in favor of the ingroup. In Studies 2 and 3, intragroup approval (vs. disapproval) of an ingroup member who used the LIB enhanced the expression of pro-ingroup bias. By providing the first demonstration of how the LIB relates to intragroup normative processes, our studies highlight a new path by which the LIB helps perpetuate intergroup bias.     

Narcissism lost: On translating and being translated1

The authors present a detailed account of the experiences shared in translating and having one’s work translated. Carneiro maintains that, in order to communicate with their readers, writers should relinquish the narcissistic satisfaction they derive from their texts in the original. Beyond this, she feels that, owing to a good understanding between her and her translator, the creativity in her original text persists in the translation. Brakel introduces himself to the IJPA readership and shows how he works when translating the cultural and linguistic nuances and peculiarities of Brazilian Portuguese. He concludes with some thoughts about the affect he experiences from his original work and the work he has translated.     

The psychological distance of memories: Examining causal relations with mood and self-esteem in young,middle-aged and older adults

Three studies examined the self-enhancement function of autobiographical memory (measured with subjective temporal distance of memories). Participants recalled a memory of an attained and a failed goal and rated the subjective distance between each memory and the present. Study 1 showed that young adults with higher self-esteem felt closer to memories of attained goals and farther from failure memories than those with lower self-esteem. In Study 2, young, middle-aged and older adults with higher self-esteem felt closer to success memories, whereas self-esteem was unrelated to the temporal distance of failure memories. In both studies, feeling closer to success memories (and far from failure) led to enhanced mood. In Study 3, state self-esteem was experimentally manipulated. The manipulation had no effect on young and older adults, but middle-aged adults whose self-esteem was decreased, felt closer to success memories than failure memories. Results are discussed in relation to the temporal self-appraisal theory.     

The discovery and comparison of symbolic magnitudes

Humans and other primates are able to make relative magnitude comparisons, both with perceptual stimuli and with symbolic inputs that convey magnitude information. Although numerous models of magnitude comparison have been proposed, the basic question of how symbolic magnitudes (e.g., size or intelligence of animals) are derived and represented in memory has received little attention. We argue that symbolic magnitudes often will not correspond directly to elementary features of individual concepts. Rather, magnitudes may be formed in working memory based on computations over more basic features stored in long-term memory. We present a model of how magnitudes can be acquired and compared based on BARTlet, a representationally simpler version of Bayesian Analogy with Relational Transformations (BART; Lu, Chen, & Holyoak, 2012). BARTlet operates on distributions of magnitude variables created by applying dimension-specific weights (learned with the aid of empirical priors derived from pre-categorical comparisons) to more primitive features of objects. The resulting magnitude distributions, formed and maintained in working memory, are sensitive to contextual influences such as the range of stimuli and polarity of the question. By incorporating psychological reference points that control the precision of magnitudes in working memory and applying the tools of signal detection theory, BARTlet is able to account for a wide range of empirical phenomena involving magnitude comparisons, including the symbolic distance effect and the semantic congruity effect. We discuss the role of reference points in cognitive and social decision-making, and implications for the evolution of relational representations.
