In this chapter, Münsterberg describes a number of cases and experiments that illustrate the vagaries and unreliability of human perception and memory, producing what he refers to as “illusions.” This chapter focuses on the illusions of unconscious transference, change blindness, and the confidence–accuracy relationship. Unconscious transference occurs when an eyewitness identifies an innocent bystander as a culprit because of a previous encounter with the bystander in another context. Change blindness is the inability to notice a change in a visual stimulus. The confidence–accuracy relationship has been one of the most controversial and complex aspects of eyewitness memory, as the strength of the relationship varies depending on a number of individual and situational characteristics, as well as methodological and analytic choices.

Numerous studies of withdrawal from work organizations have considered demographic and other personal history characteristics of leavers. Relatively few of these studies have incorporated dynamic situational characteristics in their designs. In the present effort, the relationship between perceived characteristics of the work environment and stated intentions to reenlist were examined for two groups of first-term Navy enlistees: 198 with less than one year of active duty and less than six months of sea duty, and 516 personnel with more than one year of active duty and more than six months of sea time. It was hypothesized that: (a) the relationship between organizational conditions and intent to reenlist would be weaker for new members than for experienced men, (b) that new personnel would be most likely to change their intentions over time, and (c) that new personnel would quickly assimilate the beliefs, values, and perspectives of their more experienced co-workers. Hypothesis 1 was not supported although the pattern of relationships was in the predicted direction. Hypotheses 2 and 3 were supported. The authors discuss the need for research which emphasizes the impact of initial expectation and organizational socialization on the withdrawal decision process.

The Relationship

Human perception is inherently multisensory, with cross-modal integration playing a critical role in generating a coherent perceptual experience. To understand the causes of pleasurable experiences, we must understand whether and how the relationship between separate sensory modalities influences our experience of pleasure. We investigated the effect of congruency between vision and audition in the form of temporal alignment between the cuts in a video and the beats in an accompanying soundtrack. Despite the subliminal nature of the manipulation, a higher perceptual pleasure was found for temporal congruency compared with incongruency. These results suggest that the temporal aspect of the interaction between the visual and auditory modalities plays a critical role in shaping our perceptual pleasure, even when such interaction is not accessible to conscious awareness.

Abstract Study Objectives Published research indicates that sleep is involved in emotional information processing. Using a fear-potentiated startle (FPS) and nap sleep protocol, we examined the relationship of emotional learning with REM sleep (REMS) in trauma-exposed participants. We also explored the roles of PTSD symptoms, biological sex, and an integrative measure of polysomnography-measured (PSG) sleep in the learning-sleep relationship. Methods After an adaptation nap, participants (N=46) completed 2 more visits (counterbalanced): a stress-condition visit, which included FPS conditioning procedures prior to a nap and assessment of learning retention and fear extinction training after the nap, and a control visit, which included a nap opportunity without stressful procedures. FPS conditioning included a “fear” visual stimulus paired with an air blast to the neck and a “safety” visual stimulus never paired with an air blast. Retention and extinction involved presentation of the visual stimuli without the air blast. Primary analyses examined the relationship between FPS responses pre- and post- sleep with stress-condition REMS duration, controlling for control-nap REMS duration. Results Higher safety learning predicted increased REMS and increased REMS predicted more rapid extinction learning. Similar relationships were observed with an integrative PSG sleep measure. They also showed unexpected effects of PTSD symptoms on learning and showed biological sex effects on learning-sleep relationships. Conclusions Findings support evidence of a relationship between adaptive emotional learning and REMS. They underscore the importance of examining sex effects in sleep-learning relationships. They introduce an integrative PSG sleep measure with potential relevance to studies of sleep and subjective and biological outcomes.

The main purpose of this study is to examine the mediating role of situational characteristics on the relationship between communication strategies and information choice strategy of the Arab tourists in Malaysia. The study adopted a cross-sectional design with a quantitative survey approach. Overall, the study finds that situational characteristics significantly mediate the influence of information source on the information choice strategy of the Arab tourists but not on the relationship between information source and information choice. The study therefore concludes among others that situational characteristic can only explain the influence of information channels on the information choice strategy but not on the influence of information source on the information choice strategy.

ABSTRACTIncreased sensitivity to light is common following concussion. Viewing a flickering light can also produce uncomfortable somatic sensations like nausea or headache. Here we examined effects evoked by viewing a patterned, flickering screen in a cohort of 81 uninjured youth athletes and 84 youth with concussion. We used exploratory factor analysis and identified two primary dimensions of variation: the presence or absence of visually evoked effects, and variation in the tendency to manifest effects that localized to the eyes (e.g., eye watering), versus more generalized neurologic symptoms (e.g., headache). Based on these two primary dimensions, we grouped participants into three categories of evoked symptomatology: no effects, eye-predominant effects, and brain-predominant effects. A similar proportion of participants reported eye-predominant effects in the uninjured (33.3%) and concussion (32.1%) groups. By contrast, participants who experienced brain-predominant effects were almost entirely from the concussion group (1.2% of uninjured, 35.7% of concussed). The presence of brain-predominant effects was associated with a higher concussion symptom burden and reduced performance on visio-vestibular tasks. Our findings indicate that the experience of negative constitutional, somatic sensations in response to a dynamic visual stimulus is a salient marker of concussion and is indicative of more severe concussion symptomatology. We speculate that differences in visually evoked effects reflect varying levels of activation of the trigeminal nociceptive system.

Abstract. In this study we investigate what poetry written about volcanoes from the 1800s to the present day reveals about the relationship between volcanoes and the societies and times represented by poets who wrote about them, including how it evolved over that time frame. In order to address this research question, we conducted a qualitative content analysis of a selection of 34 English-language poems written about human–volcano interactions. Firstly, we identified the overall connotation of each poem. Then, we recognised specific emerging themes and grouped them in categories. Additionally, we performed a quantitative analysis of the frequency with which each category occurs throughout the decades of the dataset. This analysis reveals that a spiritual element is often present in poetry about volcanoes, transcending both the creative and destructive power that they exert. Furthermore, the human–volcano relationship is especially centred around the sense of identity that volcanoes provide to humans, which may follow from both positive and negative events. These results highlight the suitability of poetry as a means to explore the human perception of geologic phenomena. Additionally, our findings may be relevant to the definition of culturally appropriate communication strategies with communities living near active volcanoes.

Change blindness is a phenomenon in which individuals fail to detect seemingly obvious changes in their visual fields. Like humans, several animal species have also been shown to exhibit change blindness; however, no species of New World monkey has been tested to date. Nine capuchins (Sapajus [Cebus] apella) were trained to select whether or not a stimulus changed on a computerized task. In four phases of testing, consisting of full image changes, subtle occlusion changes, and two levels of feature location changes, the search display and mask durations were systematically varied to determine whether capuchins experienced change blindness and in what contexts. Only the full image change test yielded significant results, with subjects detecting changes most accurately with longer search displays and, perplexingly, least accurately when there was no mask. No interactions between search display and mask durations were found in any test phase, suggesting that the relationship between the two parameters may not be important to how capuchins perceive changes. While it is possible that capuchins do not experience change blindness, we suspect that a mix of experimental design, the difficulty of the task, and the inability to verify how closely the subjects attended to each trial contributed to the lack of significant results
