Picture interpretation and Jungian typology

This study examined a Jungian picture interpretation schema, which utilizes a specific quadrant method. This proposed schema, which is used in training at the C. G. Jung Institute in Zürich, attaches significance to specific areas of a drawing. The upper left of a drawing is associated with the father; the lower left with the unconscious; the lower right with the mother; and the upper right with the future. Three questions served as the foci of this study: Is the schema valid? Do certain types within Jung's personality theory respond better than others to the schema? Does the schema work best when it elicits a strong affective response from the person who created the picture? Subjects took one of two tests: a space domain test, or a colour associative test. The results revealed only two significant effects: a positive association (in the space domain test) between unconscious material with the unconscious quadrant and a negative association (in the colour associative test) of mother material with the mother quadrant. These results suggest that the Jungian quadrant schema used to interpret drawings is invalid and of minimal practical utility. Other methods of picture interpretation are discussed as well as suggestions for future research that would be helpful to this field.     

Chronic amphetamine exposure during the preweanling period does not affect avoidance learning or novelty-seeking of adult rats

The purpose of the present study was to determine whether exposure to amphetamine during the preweanling period would impact the learning or reward processes of rats tested in adulthood. In three experiments we examined whether amphetamine treatment (0-10 mg/kg per day) on postnatal days 11-17 altered the subsequent performance of adult Sprague-Dawley rats on a step-down passive avoidance, active avoidance, or novelty-seeking task. There was no evidence that postnatal amphetamine exposure affected performance on any of these tasks. These results suggest that the long-term impact of pre- and postnatal psychostimulant exposure differs, because in utero stimulant treatment is known to produce learning deficits and decrease reinforcement efficacy of rats tested in adulthood.     

Effects of the Novel Acetylcholinesterase InhibitorN-Octyl-1,2,3,4-tetrahydro-9-aminoacridine on Locomotor Activity and Avoidance Learning in Mice

The acetylcholinesterase reversible inhibitorN-octyl-1,2,3,4-tetrahydro-9-aminoacridine (THA-C8) is a new synthesized derivative of tacrine (THA) characterized by an alkyl chain in the molecular structure which ameliorates the penetrability of the compound into the central nervous system. THA-C8 (0.1–5 mg/kg) significantly reduced spontaneous locomotor activity in CD1 mice at a dose of 3 mg/kg. Moreover, THA-C8 (0.2–2 mg/kg) significantly improved shuttle-box avoidance acquisition at doses (0.25, 0.3, 1 mg/kg) not affecting locomotion and that are much lower than the doses reported to be effective for THA in animal models. From the data reported it seems that the new compound could be interesting for therapeutic purposes.     

Distractor effect on the latent inhibition of conditioned flavor aversion in rats

Using a conditioned flavor aversion procedure with rats as subjects, the effect of the addition of a distractor stimulus on the magnitude of the latent inhibition effect was examined. Experiment 1 showed that latent inhibition to vinegar was attenuated by the addition of sucrose during preexposure. On the other hand, sucrose added during conditioning to vinegar did not attenuate latent inhibition. It was also found that the degree of latent inhibition to the vinegar-sucrose compound solution was less when vinegar alone was preexposed (i.e., when sucrose was added only during conditioning) than when the compound solution was preexposed (i.e., when sucrose was added both during preexposure and during conditioning). Experiment 2 gave similar results but with sucrose assigned as the target flavor and vinegar as the distractor. These findings are in full agreement with the generalization decrement account of latent inhibition.     

Two-step communication for the interaction between automated vehicles and pedestrians

An important challenge of automated vehicles (AV) will be the cooperative interaction with surrounding road users such as pedestrians. One solution to compensate for the missing driver-pedestrian interaction might be explicit communication via external human machine interfaces (eHMIs). Additionally, implicit communication such as a vehicle pitch motion might support AVs when interacting with pedestrians. While previous work explored various explicit and implicit communication cues, these concepts communicated the intention of the AV at one single time point. Currently, empirical findings on two-step communication lack so far. In this study, we empirically test the effect of a two-step AV communication that uses an implicit cue at a long distance and subsequently provides an implicit or explicit cues at a short distance. We compared its efficiency to single-step communication concepts providing implicit or explicit cues at the shorter distance only. To explore whether the right communication cue is used at the right distance, we analyzed pedestrians’ fixations while approaching an AV using an eye tracking device.We conducted a virtual reality study (N = 30) with AV communication concept that provided an active pitch motion or an eHMI and compared them with a two-step AV communication concept that provided an additional active pitch motion at a long distance when approaching the pedestrian. Furthermore, we recorded pedestrians’ fixation behavior while the AV approached.Consistently to previous work, single-step AV communication showed a beneficial effect on crossing behavior. Pedestrians initiated their crossing earlier while approaching an AV with an active pitch motion or an eHMI compared to the baseline condition. While active pitch motion reduced subjective safety feeling, eHMI increased it. However, the two-step communication concept did not further improve pedestrians’ crossing initiation times and their safety feeling. The pattern of fixation behavior differed as a function of AV distance. When the approaching AV was far away, pedestrians exclusively looked at the environment. During the approach, pedestrians gradually fixated the bumper and the hood and only then the windshield of the AV. Hence, it seems to be useful to present an AV intent communication at a certain distance from the pedestrian. These findings posit the importance of considering pedestrians’ fixation behavior when developing communication concepts between AVs and pedestrians.     

Science‐based interviewing: Information elicitation

This article describes an ethical and effective science‐based model of interviewing. An initial planning phase assists the investigative team in separating facts from inferences, decreases the likelihood of errors based on cognitive biases, and prompts careful preparation of the environment. The interview begins with an explanation of why the subject is being questioned. The interviewer then metaphorically hands the interview over to the subject, making him the talker and the interviewer the listener. The interviewer engages in active listening, soliciting as much information from the subject as possible by deploying tactics that enhance memory based on science, including elements of the cognitive interview. Cues to deception are found in the details of the story, rather than in signs of anxiety or nonverbal behaviours, and by deploying Strategic Use of Evidence. This model has been shown to increase cooperation, decrease resistance, and provoke useful information in real‐world criminal interviews.     

Cross-border mobility,European identity and participation among European adolescents and young adults

Abstract

Cross-border mobility is one of the most important factors that are assumed to strengthen young people’s commitment as European citizens. However, the existing empirical evidence does not provide consistent support. In this paper, we tested the hypothesis that cross-border mobility is associated with a stronger European identification, more positive attitudes toward the EU, and with specific visions of the EU, and that these factors, in turn, have a positive effect on engagement at EU level. Data were collected as part of the multinational research project CATCH-EyoU. Analyses were performed controlling for gender, income, country, and migrant status. Results mostly confirmed the hypotheses among both adolescents and young adults, and for both short-term and long-term mobility. EU level participation and EU voting intentions appeared to be influenced by partly different factors. The implications of the findings, both at theoretical level and for the development of international mobility programs, are discussed.     

Passion,vitality and life satisfaction for physically active old adults

In Arabic world, few studies are interested in psychological factors influencing the physically active old adults. The specific goals of the present research are the following: (i) test the factor structure and invariance tests for gender and physical activities for the Arabic version of the passion scale; (ii) test a model that describes a mediator role of subjective vitality in the relationships between passion and life satisfaction (iii) test the presence of differences for gender, physical activity practice, education level and age on passion. Two studies were conducted with 551 physically active Egyptian old adult (n = 354; n = 197). Passion, Subjective vitality and Life Satisfaction scales were administered. Passion scale composed of two subscales (harmonious and obsessive). Strong support for the complete invariance between groups. Subjective vitality was a mediator in the relationships between harmonious passion and life satisfaction. Education level and age had an effect on passion subscales.     

熟悉性和兼容性对复合社会范畴刻板印象表征的影响

通过对启动任务范式的改进,运用3个实验全面考察了复合社会范畴本身的熟悉性和兼容性对复合社会范畴刻板印象中抽象表征和样例表征策略运用的影响。实验1分别以熟悉的、不熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对熟悉的复合范畴采用抽象表征,而对不熟悉且在刻板印象上不兼容的复合范畴的表征采用样例表征;实验2以熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对于熟悉但构成范畴不兼容的复合范畴的表征也采用样例表征;实验3采用相同的实验范式,在描述和定义两种启动任务中设置子范畴间兼容的刻板特质词和不兼容的刻板特质词,选择与实验2相同的复合范畴"男中学教师"为目标群体,更加严密地证实和整合了实验1与实验2的研究结论。3个实验的结果说明复合范畴刻板印象的表征关键取决于兼容性,一旦复合社会范畴的构成范畴在刻板印象上不兼容,那么对于这一复合社会范畴刻板印象的表征采用样例表征。当构成复合范畴的两个子范畴之间兼容时,熟悉性成为刻板印象运用抽象表征还是样例表征的影响因素,无论是对内群体的刻板印象还是外群体的刻板印象,对熟悉的刻板特质词的表征运用抽象表征。
