Does crossmodal correspondence modulate the facilitatory effect of auditory cues on visual search?

The ??pip-and-pop effect?? refers to the facilitation of search for a visual target (a horizontal or vertical bar whose color changes frequently) among multiple visual distractors (tilted bars also changing color unpredictably) by the presentation of a spatially uninformative auditory cue synchronized with the color change of the visual target. In the present study, the visual stimuli in the search display changed brightness instead of color, and the crossmodal congruency between the pitch of the auditory cue and the brightness of the visual target was manipulated. When cue presence and cue congruency were randomly varied between trials (Experiment 1), both congruent cues (low-frequency tones synchronized with dark target states or high-frequency tones synchronized with bright target states) and incongruent cues (the reversed mapping) facilitated visual search performance equally, relative to a no-cue baseline condition. However, when cue congruency was blocked and the participants were informed about the pitch?Cbrightness mapping in the cue-present blocks (Experiment 2), performance was significantly enhanced when the cue and target were crossmodally congruent as compared to when they were incongruent. These results therefore suggest that the crossmodal congruency between auditory pitch and visual brightness can influence performance in the pip-and-pop task by means of top-down facilitation.     

To believe or not to believe? The joint impact of faultlines and pro-diversity beliefs on diplomats’ performance

Diversity faultlines can have a detrimental impact on team performance. To test whether this impact depends on leaders’ and members’ pro-diversity beliefs, we examined 41 leaders and 219 members of teams working for the German Ministry of Foreign Affairs. Findings indicated that the negative impact of diversity faultlines on team performance was weakest when leaders and members held strong pro-diversity beliefs. However, we did not find support for the assumed two-way interactions between faultline strength and leaders’ or members’ pro-diversity beliefs or the mediating effect of Leader-Member Exchange. Our results highlight the joint impact of leaders’ and members’ pro-diversity beliefs for attenuating the negative consequences of diversity faultlines on team performance.     

Correlation and explaining variance: To square or not to square?

Despite previous articles dating back 80 years, the questions of whether and when to square correlations continue to puzzle and confuse researchers. In this editorial, I point out that correlations can serve two independent purposes: they can be measures of effect size in themselves and their function as regression coefficients can be used to estimate proportion of variance in one measure for which another measure accounts. Using examples relevant to intelligence researchers, I show that the answer to the question of whether or not to square a correlation is ‘it depends.’ It depends on the purpose and it depends on the underlying theoretical model of the causal association between the variables.     

To know or not to know: an application of Bion’s K and –K to child treatment1

The authors discuss an application of Bion’s conceptualisation of thinking and non-thinking states (K and –K links) to the treatment of a nine-year-old girl. The authors consider Bion’s interrelated concepts such as K and –K, container/contained, maternal reverie, and the development of thinking through alpha function to be highly applicable to child treatment. The afore-mentioned conceptual elements are used to elucidate case material over two consecutive hours. A K link is established between therapist and patient, the fragility of which link is then demonstrated by its deterioration into a –K link. Complex issues about knowing and not knowing are central in this girl’s clinical presentation. She was conceived through in vitro fertilisation (IVF), and subsequently diagnosed with cerebral palsy. The authors consider the emotional impact of this origin story and how the parents relate to it. The authors discuss how parents sometimes cope with perceived losses by wishing to shield or protect their children. This can have repercussions for children’s efforts to know (K) and not to know (?K). The fear that emotional knowledge will be too painful to bear can interfere with ‘learning from experience’. Bion’s premise that the purpose of analysis is the growth of the mind is synonymous with the child analyst’s goal of fostering development and understanding impediments to development.

Infants’ responsiveness to the auditory and visual attributes of a sounding/moving stimulus

Responses to unimodal and multimodal attributes of a compouMauxlitoryMsuat stimulus were investigated in 4-, 6-, 8-, and 10-month-old infants. First, infants were habituated to a compound stimulus consisting of a visual stimulus that moved up anddown on a video monitor and a sound that occurred each time the visual stimulus reversed direction at the bottom. Once each infant met a habituation criterion, a series of test trials was administered to assess responsiveness to the components of the compound stimulus. Response was defined as the total duration of visual fixation in each trial. In the two unimodal test trials, the rate at which the component was presented was changed while the rate of the other component remained the same, whereas in the bimodal test trial the rate of both components was changed simultaneously. Results indicated that infants at each age successfully discriminated the bimodal and the two unimodal changes and that regression to the mean did not account for the results. Results also showed that disruption of the temporal relationship that accompanied the change in rate in the two unimodal test trials was also discriminable, but rate changes appeared to play a greater role in responsiveness than did synchrony changes. Considered together with results from similar prior studies, the current results are consistent with the modality appropriateness hypothesis in showing that discrimination of temporal changes in the auditory and visual modalities is dependent on the specialization of the sensory modalities.     

Learning lyrics: To sing or not to sing?

According to common practice and oral tradition, learning verbal materials through song should facilitate word recall. In the present study, we provide evidence against this belief. In Experiment 1, 36 university students, half of them musicians, learned an unfamiliar song in three conditions. In the sung-sung condition, the song to be learned was sung, and the response was sung too. In the sung-spoken condition, the response was spoken. In the divided-spoken condition, the presented lyrics (accompanied by music) and the response were both spoken. Superior word recall in the sung-sung condition was predicted. However, fewer words were recalled when singing than when speaking. Furthermore, the mode of presentation, whether sung or spoken, had no influence on lyric recall, in either short- or long-term recall. In Experiment 2, singing was assessed with and without words. Altogether, the results indicate that the text and the melody of a song have separate representations in memory, making singing a dual task to perform, at least in the first steps of learning. Interestingly, musical training had little impact on performance, suggesting that vocal learning is a basic and widespread skill.     

To commit or not commit to human life: Children of victims and victimizers—All

The author discusses the impact of the Holocaust on both the children of victims and victimizers and reports on empirical researches conducted among Israeli student health professionals and others as to how ready they, the people of the victims, are to approve of and to participate in various programs and events which take the lives of helpless others, and reports disturbing results. He concludes that making a commitment to human life is the single most important task for all of us.     

Impact of the driver’s visual engagement on situation awareness and takeover quality

During automated driving (SAE Level 3), drivers can delegate control of the vehicle and monitoring of the road to an automated system. They may then devote themselves to tasks other than driving and gradually lose situational awareness (SA). This could result in difficulty in regaining control of the vehicle when the automated system requires it. In this simulator study, the level of SA was manipulated through the time spent performing a non-driving task (NDRT), which alternated with phases where the driver could monitor the driving scene, prior to a critical takeover request (TOR). The SA at the time of TOR, the visual behaviour after TOR, and the takeover quality were analysed. The results showed that monitoring the road just before the TOR allowed the development of limited perception of the driving situation, which only partially compensated for the lack of a consolidated mental model of the situation. The quality of the recovery, assessed through the number of collisions, was consistent with the level of development of SA. The analysis of visual behaviour showed that engagement in the non-driving task at the time of TOR induced a form of perseverance in consulting the interface where the task was displayed, to the detriment of checking the mirrors. These results underline the importance of helping the driver to restore good SA well in advance of a TOR.     

Meaning in learning: Contextual cueing relies on objects’ visual features and not on objects’ meaning

People easily learn regularities embedded in the environment and utilize them to facilitate visual search. Using images of real-world objects, it has been recently shown that this learning, termed contextual cueing (CC), occurs even in complex, heterogeneous environments, but only when the same distractors are repeated at the same locations. Yet it is not clear what exactly is being learned under these conditions: the visual features of the objects or their meaning. In this study, Experiment 1 demonstrated that meaning is not necessary for this type of learning, as a similar pattern of results was found even when the objects’ meaning was largely removed. Experiments 2 and 3 showed that after learning meaningful objects, CC was not diminished by a manipulation that distorted the objects’ meaning but preserved most of their visual properties. By contrast, CC was eliminated when the learned objects were replaced with different category exemplars that preserved the objects’ meaning but altered their visual properties. Together, these data strongly suggest that the acquired context that facilitates real-world objects search relies primarily on the visual properties and the spatial locations of the objects, but not on their meaning.     

Whistleblowing of bullying in professional football: To report or not to report?

Only recently has research begun to focus on workplace bullying within organizations outside of traditional white-collar industries, such as professional football. While this is an important development, there remains a lack of understanding around the reporting of bullying in professional sport. In this paper, the authors explore how the professional football workplace shapes perceptions of whistleblowing and unearths individual perceptions around reporting bullying behavior. We used a phenomenological approach to gain rich experiential data from eighteen male professional football players in the UK. Interview data were analyzed in accordance with the principles of Interpretative Phenomenological Analysis. Two superordinate themes were identified from the analysis, (a) professional football’s influence on whistleblowing, and (b) the challenges of reporting bullying. These themes highlighted that the unique, institutionalized nature of professional football interacts with participants’ ability to report bullying behavior. The participants’ accounts revealed divergent perceptions around how professional football shapes the degree to which players feel they can report bullying behavior. It was apparent that the authoritarian, often abusive and intimidatory nature of professional football significantly impacts whistleblowing. Our findings demonstrate the importance of workplace context when exploring the reporting of bullying behavior. They also demonstrate the need to address organizational culture and differentiate bullying education programs to alternative workplaces.     

Predicting pedestrians’ intention to cross the road in front of automated vehicles in risky situations

Due to the absence of a human driver, the introduction of fully automated vehicles (FAVs) may bring new safety challenges to the traffic system, especially when FAVs interact with vulnerable road users such as pedestrians. To ensure safer interactions between pedestrians and FAVs, this questionnaire-based study aims to understand Australian pedestrians’ intention to engage in risky road-crossing behaviors when they interact with FAVs vs. human-driven vehicles (HDVs). A 2 × 2 between-subject design was utilized, in which two risky road-crossing scenarios were designed and took into account the vehicle type (FAV vs. HDV) and vehicle speed (30 km/h vs. 50 km/h). A total of 493 participants (aged 18–77) were randomly assigned to one of the four experimental conditions and completed an online questionnaire based on the extended Theory of Planned Behavior (TPB). This questionnaire measured pedestrians’ intentions to cross the road in the assigned scenarios as well as the motivational factors behind these intentions in terms of attitude, subjective norm, perceived behavioral control, perceived risk and trust in the vehicle. The results show that pedestrians had significantly higher intentions to cross the road in front of approaching FAVs than HDVs. Participants also reported a lower risk perception of crossing in front of FAVs and greater trust in this type of vehicle. Attitude, subjective norm, and perceived behavioral control were significant predictors of intentions to engage in risky road-crossing behavior. Findings of this study provide important implications for the development and implementation of FAVs in the future road transport system.     

Jury simulation studies: To exclude or not to exclude participants based on a lack of comprehension of the case?

Jury simulation research has been the subject of longstanding criticism in regards to ecological validity. One additional factor that has received little attention that may also impact the generalizability of this research relates to excluding participants based on their memory of, or their attention paid to, the case. In order to determine how common this exclusion is, the authors conducted a scoping review of jury simulation studies within the last 10 years across three major legal psychology journals. The review revealed variability in if and how studies excluded on the basis of poor attention or for failing manipulation or general memory checks. In addition, studies that did exclude on this basis varied greatly in the proportion of the sample that was excluded. Recommendations are provided in order to assist jury researchers in future with how best to manage exclusions on the basis of juror memory and attention.     

To reverse or not to reverse: when is an ambiguous figure not ambiguous?

The role of bottom-up processes in our perception of reversible figures was examined. In Experiment 1 the overlapping squares figure and nonsense reversible figures were used. The effects of adapting subjects for differing durations to an unambiguous version of the figure before presentation of the traditional reversible figure were determined under conditions of varying precision of fixation. In Experiment 2 the research was expanded to other examples of reversible figures. In both experiments, results with two dependent measures (the subject's first percept and the number of reversals reported) were generally consistent with the interpretation of bottom-up processes underlying the adaptation effects. However, the crucial role of stimulus and procedural variables and the differential sensitivity of the two dependent measures was demonstrated.     

2 B kreativ’ or not to be creative: Textisms and texters’ creativity

IntroductionText messages are particularly popular among young people. Studies have focused on the links between writers’ unconventional spelling and literacy skills. Creativity gives the possibility to cope with the numerous changes people have to face.ObjectiveThe present research aimed to examine the relation between the creative potential of texters (text-message writers) and their use of textisms (a change in a word's orthographic form as compared to traditional writing).MethodTwo corpora were compiled: one of 285 elicited text messages and one of 580 naturalistic text messages produced in daily-life situations by undergraduates (n = 29, 20–23 years of age). Two types of textisms were measured: those consistent with traditional written code and those breaking with traditional written code. Four scores of creative potential were considered: graphic divergent thinking, verbal divergent thinking, graphic integrative thinking and verbal integrative thinking.ResultsThe results showed negative correlations between the level of creativity and the density of textisms. Overall, texters who were creative in divergent thinking produced fewer textisms breaking with traditional written code.ConclusionThe results of our study are discussed with regard to the texters’ flexibility and ability to adapt or appropriately address their interlocutor.     

To act or not to act? Student-athlete perceptions of social justice activism

Issues related to social justice and activism have always permeated sports, but recently, due to the high profile cases of several elite-level athletes (i.e., Colin Kaepernick, Megan Rapinoe), these issues have become much more prominent in the contemporary sporting climate. Even though these highly visible actions are publicized in today’s media environment, little is known about how collegiate student-athletes perceive engaging in social justice activism. Therefore, the current study surveyed 2,092 collegiate student-athletes on their attitudes toward activism engagement using a theory of planned behavior framework with particular attention paid to how gender and ethnicity/race influenced these relationships. A series of MANOVAs indicated that female student-athletes, in relation to male student athletes, and student-athletes of color, in comparison to White student-athletes, held higher perceptions on most of the subscales related to activism. A hierarchical multiple regression analysis indicated attitudes, perceived behavioral control, and subjective norms were significant predictors of athletes’ intention to engage in activism. In addition, interactions of the three predictors with race and gender influenced the final regression model indicating the strength of each predictor was impacted by athlete race and gender. Future research directions and implications for programming in relation to study findings are discussed.     

Evaluating the Impact of Careless Responding on Aggregated-Scores: To Filter Unmotivated Examinees or Not?

When examinees' test-taking motivation is questionable, practitioners must determine whether careless responding is of practical concern and if so, decide on the best approach to filter such responses. As there has been insufficient research on these topics, the objectives of this study were to: a) evaluate the degree of underestimation in the true mean when careless responses are present, and b) compare the effectiveness of two filtering procedures in purifying biased aggregated-scores. Results demonstrated that: a) the true mean was underestimated by around 0.20 SDs if the total amount of careless responses exceeded 6.25%, 12.5%, and 12.5% for easy, moderately difficult, and difficult tests, respectively, and b) listwise deleting data from unmotivated examinees artificially inflated the true mean by as much as .42 SDs when ability was related to careless responding. Findings from this study have implications for when and how practitioners should handle careless responses for group-based low-stakes assessments.     

Evaluating the influence of approaching vehicles on pedestrian’s visual patterns and crossing behaviors at an uncontrolled crosswalk

The visual behaviors and movement characteristics of pedestrians are related to their surrounding potential safety hazards, such as approaching vehicles. This study primarily aimed to investigate the visual patterns and walking behaviors of pedestrians interacting with approaching vehicles. Field experiments were conducted at two uncontrolled crosswalks located at the Cuihua and Yanta roads in Xi’an, China. The visual performance of pedestrians was assessed using the eye tracking system from SensoMotoric Instruments (SMI). Moreover, motion trajectories of the pedestrians and approaching vehicles were obtained using an unmanned aerial vehicle. Subsequently, the visual attributes and movement trajectories of pedestrians and motion trajectories of approaching vehicles were statistically analyzed. The results showed that approaching vehicles distracted the fixation of crossing pedestrians significantly, and occupied 29.5% of the total duration of fixation; that is, pedestrians always directed more fixation points to the approaching vehicles compared to other stimuli. As a vehicle approached, pedestrians’ fixation shifted from other areas of interest to the vehicle. Moreover, an increase in the velocity of the vehicle and a closer distance between pedestrian and the vehicle resulted in an increase in the pedestrians’ duration of fixation on the approaching vehicle, and they implemented more saccades. Furthermore, approaching vehicle’s velocity and distance between pedestrian and approaching vehicle are not significantly associated with pedestrian’s movement attributes. These findings provide insights into the crossing behavior of pedestrians during pedestrian-vehicle interactions, which could assist future researchers and policy makers.
