The Effect of Lifeguard Experience upon the Detection of Drowning Victims in a Realistic Dynamic Visual Search Task

Lifeguard surveillance is a complex task that is crucial for swimmer safety, though few studies of applied visual search have investigated this domain. This current study compared lifeguard and non‐lifeguard search skills using dynamic, naturalistic stimuli (video clips of confederate swimmers) that varied in set size and type of drowning. Lifeguards were more accurate and responded faster to drowning targets. Differences between drowning targets were also found: Passive drownings were responded to less often, but more quickly than active drownings, highlighting that passive drownings may be less salient but are highly informative once detected. Set size effects revealed a dip in reaction speeds at an intermediate set‐size level, suggesting a possible change in visual search strategies as the array increases in size. Nonetheless, the ability of the test to discriminate between lifeguards and non‐lifeguards offers future possibilities for training and assessing lifeguard surveillance skills.

Visual search for drowning swimmers: Investigating the impact of lifeguarding experience

How does domain expertise influence dynamic visual search? Previous studies of visual search often use abstract search arrays that are devoid of applied context, with comparatively few studies exploring applied naturalistic and dynamic settings. The current research adds to this literature by examining lifeguard drowning‐detection across two studies using naturalistic, dynamic search tasks. Behavioural responses and eye‐movement data were recorded as participants watched staged video clips and attempted to identify if a swimmer was drowning. The results demonstrate lifeguard superiority in response times to drowning events, compared to non‐lifeguards. No differences between lifeguard and non‐lifeguard eye‐movements were noted however. This suggests that the experiential benefit in response times results from other underlying processes, rather than any scanning benefits. This research highlights the complex nature of naturalistic and dynamic searches, while demonstrating the robust nature of simulated videos in producing experience effects in visual search.     

What’s the <Emphasis Type="Italic">Matter</Emphasis> with cognition? A ‘Vygotskian’ perspective on material engagement theory

The cross-disciplinary framework of Material Engagement Theory (MET) has emerged as a novel research program that flexibly spans archeology, anthropology, philosophy, and cognitive science. True to its slogan to ‘take material culture seriously’, “MET wants to change our understanding of what minds are and what they are made of by changing what we know about what things are and what they do for the mind” (Malafouris 2013, 141). By tracing out more clearly the conceptual contours of ‘material engagement,’ and firming up its ontological commitments, the main goal of this article is to help refine Malafouris’ fertile approach. In particular, we argue for a rapprochement between MET and the tradition of Cultural-Historical Activity Theory, based on the ‘Vygotskian’ hypothesis of scaffolded and/or distributed cognition.     

The Role of Incentive Framing on Training and Transfer of Learning in a Visual Threat Detection Task

We examined the effects of different incentives on skill acquisition and transfer during threat detection in airline luggage screening. The incentives were presented within positive (gains) or negative (losses) frames, and points were given or taken away accordingly during training (with familiar targets) and transfer (to novel targets). During training, incentives exerted a more beneficial effect on skill acquisition than training without incentives. During transfer, incentives benefitted performance largely when presented as losses or penalties. Incentives framed as gains primed participants to say ‘yes’ more often leading to a high ratio of false positives; however, incentives framed as losses lead participants to become more selective in their ‘yes’ responses leading to a lower number of false positives but a comparable probability of correct detections. Interestingly, participants that received no training outperformed participants that received incentive‐based training, suggesting that incentives actually constrained rather than helped transfer of learning in this study.

Sensitivity to reward and punishment in major depressive disorder: Effects of rumination and of single versus multiple experiences

In the current study, we examined the postulation that rumination makes it difficult for depressed individuals to learn the exact probability that different stimuli will be associated with punishment. To do so, we induced rumination or distraction in depressed and never-depressed participants and then measured punishment and reward sensitivity with a probabilistic selection task. In this task, participants first learn the probability that different stimuli will be associated with reward and punishment. During a subsequent test phase in which novel combinations of stimuli are presented, participants’ sensitivity to reward is tested by measuring their tendency to select the stimuli that were most highly rewarded during training, and their sensitivity to punishment is tested by measuring their tendency to not select the stimuli that were most highly punished during training. Compared with distraction, rumination led depressed participants to be less sensitive to the probability that stimuli will be associated with punishment and relatively less sensitive to punishment than reward. Never-depressed participants and depressed participants who were distracted from rumination were as sensitive to reward as they were to punishment. The effects of rumination on sensitivity to punishment may be a mechanism by which rumination can lead to maladaptive consequences.     

A secondary task is not always costly: Context‐based guidance of visual search survives interference from a demanding working memory task

Repeatedly encountering a visual search display with the target located at a fixed position relative to the distractors facilitates target detection, relative to novel displays – which is attributed to search guidance by (acquired) long‐term memory (LTM) of the distractor ‘context’ of the target. Previous research has shown that this ‘contextual cueing’ effect is severely impeded during learning when participants have to perform a demanding spatial working memory (WM) task concurrently with the search task, though it does become manifest when the WM task is removed. This has led to the proposal that search guidance by LT context memories critically depends on spatial WM to become ‘expressed’ in behaviour. On this background, this study, of two experiments, asked: (1) Would contextual cueing eventually emerge under dual‐task learning conditions if the practice on the task(s) is extended beyond the short training implemented in previous studies? and given sufficient practice, (2) Would performing the search under dual‐task conditions actually lead to an increased cueing effect compared to performing the visual search task alone? The answer is affirmative to both questions. In particular, Experiment 1 showed that a robust contextual cueing effect emerges within 360–720 dual‐task trials as compared to some 240 single‐task trials. Further, Experiment 2 showed that when dual‐ and single‐task conditions are performed in alternating trials blocks, the cueing effect for the very same set of repeated displays is significantly larger in dual‐task blocks than in single‐task blocks. This pattern of effects suggests that dual‐task practice eventually leads to direct, or ‘automatic’, guidance of visual search by learnt spatial LTM representations, bypassing WM processes. These processes are normally engaged in single‐task performance might actually interfere with direct LTM‐based search guidance.     

The importance of reflection and evaluation processes in daily training sessions for progression toward elite level swimming performance

Self-regulated learning (SRL) involves self-directed metacognitive subprocesses and motivational beliefs that facilitate more effective and efficient learning. We investigated whether youth swimmers who are on track to becoming elite swimmers apply SRL subprocesses more frequently in their daily training sessions compared with swimmers who are not on this track. Insights into swimmers’ use of training-centered SRL could advance understanding about underlying individual characteristics that contribute to optimal engagement in daily training and, consequently, progression toward elite level swimming performance. We collected data on training-centered SRL subprocesses (evaluation, planning, reflection, speaking up, effort and self-efficacy) and performance data for 157 youth swimmers aged 12–21 years (73 males and 84 females). The results of a multivariate analysis of covariance revealed significantly higher scores for reflection processes during training for high-performing swimmers but lower scores for effort compared with lower-performing swimmers (p < 0.05). A closer examination of the high-performing group showed that those demonstrating greater improvement during a season scored significantly higher for evaluation processes after training compared with those evidencing less improvement during a season (p < 0.05). Significant between-group differences in SRL subprocesses remained after adjusting for differences in weekly training hours. Youth swimmers on track to becoming elite swimmers are characterized by more frequent use of reflection processes during training and evaluation processes after training, which suggests that these swimmers’ learning and training processes are more effective and efficient. Ultimately, this could contribute to a higher quality of daily training, which may result in greater improvements during a season, higher performance levels, and a greater chance of reaching the level of elite swimming performance.     

Unconsciously learning task-irrelevant perceptual sequences

We demonstrated unconscious learning of task-irrelevant perceptual regularities in a Serial Reaction Time (SRT) task in both visual and auditory domains. Participants were required to respond to different letters (‘F’ or ‘J’, experiment 1) or syllables (‘can’ or ‘you’, experiment 2) which occurred in random order. Unbeknownst to participants, the color (red, green, blue or yellow) of the two letters or the tone (1–4) of the syllables varied according to certain rules. Reaction times indicated that people indeed learnt both the color and tonal regularities indicating that task-irrelevant sequence structure can be learned perceptually. In a subsequent prediction test of knowledge of the color or tonal cues using subjective measures, we showed that people could acquire task irrelevant knowledge unconsciously.     

Meaning of Social Inclusion to Young People Not in Employment,Education or Training

The ‘social inclusion’ of young people, particularly those who are ‘not in education, employment or training’, is a contemporary concern in policy discourses. However, it has been argued that the term ‘social inclusion’ is defined by adults and imposed on young people, and there is little understanding of what ‘social inclusion’ means to young people themselves. Using a participatory methodology, this study investigated what ‘being included’ meant to young people. A qualitative approach with a thematic analysis was used to explore the accounts of 11 participants and yielded three main themes. ‘“Acceptance”—the building blocks of inclusion’ reflected the power of interpersonal acceptance in determining young people's sense of inclusion. ‘“Learning why I don't matter”—when power and discourse shape inclusion’ illustrated how social discourses and power dynamics influenced young people's experience of inclusion. ‘“Keeping up or falling behind”—internalising the discourse of inclusion’ reflected how young people internalised some of these societal definitions of inclusion and responded to them. Those who felt ‘accepted’ or ‘included’ in a ‘mainstream’ sense articulated a sense of agency and hope. For those who did not, it appeared that agency dissolved as did a sense of hope for the future. Although the participants negotiated their ‘inclusion’ through close, trusting relationships with others, the application of the societal discourses of inclusion such as productivity, independence and career mindedness had the potential to leave them feeling excluded, isolated and distressed.

Parents’ experiences of family food routines in adolescent elite-level swimming

ObjectiveParents have an important role in their child’s food routines and eating behaviour and face additional demands when that child is an athlete. Yet little is known about how parents manage providing food for their athletic child, in addition to the wider family, within the context of elite-level youth sport.MethodsSemi-structured interviews were conducted with sixteen parents (mothers = 11; fathers = 5) of elite level adolescent swimmers (i.e., competing at UK national level or above; child mean age = 15.4 years) to explore their experiences of family food routines and eating behaviour. Reflexive Thematic Analysis was used to analyse the data.ResultsParents outlined the importance of ‘optimal’ fuelling for their athletic child. Parents had an active role in their child’s eating behaviour and shaping their food choices but expressed uncertainty regarding the volume of food their child should consume and concerns regarding their child’s future relationship with food. Meticulous organisational and logistical strategies were employed to meet the extensive food requirements of their adolescent elite swimmer in the face of intensive training schedules. Such schedules also impacted food routines for the wider family (i.e., fewer family mealtimes), and on the quality of parents’ own diets.ConclusionThe findings highlight that clearer guidance is needed for parents of elite adolescent swimmers in relation to quantities of food intake and how to support a positive future relationship with food (specifically during any periods of transition in their training or out of the sport). The findings also identify a novel organisational stressor for parents in elite youth sport, in managing and prioritising their own diet. Further research is needed to explore the extent to which parental diet may be impacted by supporting an adolescent athlete.     

Developing clinical effectiveness in psychotherapy training: Action research

This study is an evaluation of a new approach to clinical training in Transactional Analysis using the methodology of action research. The evaluation focuses on the second year of training and placement‐based clinical practice at the Metanoia Institute, UK. The design of the training year was research‐based and used the concept of an ‘internship’ year. The design aimed to close the gaps between clinical practice, supervision and formal training; facilitate translation of theory into practice; and integrate findings from the ‘common factors’ research into effectiveness of psychotherapy. Training and supervision methods were linked and focused on emerging issues in clinical practice and the development of students’ capacity for critical reflection and a research attitude to practice. The evaluation was a naturalistic study which used quantitative and qualitative methodology within the action research framework to reflect on the impact of the training on the participants, the organisation and the clinical practice. The quantitative outcomes show that the project developed the effectiveness of students’ clinical practice and reflexivity. Qualitative analysis gives insight into the experiences of the participants and the emotional impact of the research process.     

The Effects of Imagery Training on Swimming Performance: An Applied Investigation

A multiple-baseline design was used to examine the influence of an imagery intervention on the performance of swimmers’ times on a thousand-yard practice set. Performance times for four swimmers were collected over a 15-week period during preseason training. The intervention took place over a 3-week period and was introduced after the fourth week of the study. The results revealed that three out of four participants significantly improved their times on the one thousand-yard practice set after being introduced to the imagery intervention. The results are discussed in terms of the implications of using imagery to improve athlete's performance on continuous tasks.     

Is it dangerous? The role of an emotional visual search strategy and threat-relevant training in the detection of guns and knives

Counter-terrorism strategies rely on the assumption that it is possible to increase threat detection by providing explicit verbal instructions to orient people's attention to dangerous objects and hostile behaviours in their environment. Nevertheless, whether verbal cues can be used to enhance threat detection performance under laboratory conditions is currently unclear. In Experiment 1, student participants were required to detect a picture of a dangerous or neutral object embedded within a visual search display on the basis of an emotional strategy ‘is it dangerous?’ or a semantic strategy ‘is it an object?’. The results showed a threat superiority effect that was enhanced by the emotional visual search strategy. In Experiment 2, whilst trainee police officers displayed a greater threat superiority effect than student controls, both groups benefitted from performing the task under the emotional than semantic visual search strategy. Manipulating situational threat levels (high vs. low) in the experimental instructions had no effect on visual search performance. The current findings provide new support for the language-as-context hypothesis. They are also consistent with a dual-processing account of threat detection involving a verbally mediated route in working memory and the deployment of a visual template developed as a function of training.     

Socio-cognitive,expertise-based and appearance-based accounts of the other-‘race’ effect in face perception: A label-based systematic review of neuroimaging results

Two competing theories explain the other-‘race’ effect (ORE) either by greater perceptual expertise to same-‘race’ (SR) faces or by social categorization of other-‘race’ (OR) faces at the expense of individuation. To assess expertise and categorization contributions to the ORE, a promising—yet overlooked—approach is comparing activations for different other-‘races’. We present a label-based systematic review of neuroimaging studies reporting increased activity in response to OR faces (African, Caucasian, or Asian) when compared with the SR of participants. Hypothetically, while common activations would reflect general aspects of OR perception, ‘race’-preferential ones would represent effects of ‘race’-specific visual appearance. We find that several studies report activation of occipito-temporal and midcingulate areas in response to faces across different other-‘races’, presumably due to high demand on the visual system and category processing. Another area reported in response to all OR faces, the caudate nucleus, suggests the involvement of socio-affective processes and behavioural regulation. Overall, our results support hybrid models—both expertise and social categorization contribute to the ORE, but they provide little evidence for reduced motivation to process OR faces. Additionally, we identify areas preferentially responding to specific OR faces, reflecting effects of visual appearance.     

Self-talk and Competitive Sport Performance

The purpose of the present study was to test the effectiveness of a 10-week self-talk intervention on competitive performance in young swimmers. Participants were 41 swimmers (M age 14.59, SD = 1.58 years), whose performance was recorded on 2 competitive occasions with a 10-week interval. In-between the 2 competitions, participants in the intervention group followed a self-talk training program. The results showed that the intervention group had greater performance improvements than the control group, thus, supporting the effectiveness of the program in enhancing sport performance in a competitive environment. The findings provide directions for the development of effective self-talk interventions.     

‘It’s about having exposure to this’: investigating the training needs of therapists in relation to the issue of anomalous experiences

Two focus groups, consisting of six participants each, were conducted to explore the training needs of therapists when working with clients reporting anomalous experiences (AEs). AEs are those that ‘depart from our own familiar personal experiences or from the more usual, ordinary, and expected experiences of a given culture and time’ [Braud, W. (2012). Health and well-being benefits of exceptional human experiences. In C. Murray (Ed.), Mental health and anomalous experience (pp. 107–124). Hauppauge, NY: Nova Science Publishers.]. A thematic analysis revealed four themes: ‘Quite often we get taken by surprise because it’s a subject we don’t talk about’, ‘It’s just having this in our vocabulary’, ‘Demystifying and valuing AEs as normal human experiences’ and ‘To ask or not to ask?’. Most of the participants felt that they were unequipped to work with clients reporting AEs and suggestions were made for overcoming this.     

Teens on the Internet—commercial application of a deconstructive analysis of ‘teen zine’ features

This paper presents the authors' approach to understanding drivers of interest for teen e‐zines (Internet magazines). The paper shows how a deconstruction of the current set of e‐zines provides the raw material for a conjoint measurement study, whereby the elements are mixed and matched in order to create new test concepts. From reactions to those test concepts one can identify four newly emerging segments: the ‘indifferents’, the ‘adults in training’, the ‘media and me’ and the ‘talk and celebrate being a teen’. Deconstruction applied to the competitive frame provides both a deeper understanding of the e‐zine landscape and input for newer and better e‐zines that are targeted to specific mindsets.

The Big Test of Corroboration

This paper presents a new ‘discontinuous’ view of Popper’s theory of corroboration, where theories cease to have corroboration values when new severe tests are devised which have not yet been performed, on the basis of a passage from The Logic of Scientific Discovery. Through subsequent analysis and discussion, a novel problem for Popper’s account of corroboration, which holds also for the standard (‘continuous’) view, emerges. This is the problem of the Big Test: that the severest test of any hypothesis is actually to perform all possible tests (when ‘possible’ is suitably interpreted). But this means that Popper’s demand for ‘the severest tests’ amounts simply to a demand for ‘all possible tests’. The paper closes by considering how this bears on accommodation vs. prediction, with respect to corroboration.     

Working memory training improvements and gains in non-trained cognitive tasks in young and older adults

Previous studies on working memory training have indicated that transfer to non-trained tasks of other cognitive domains may be possible. The aim of this study is to compare working memory training and transfer effects between younger and older adults (n = 60). A novel approach to adaptive n-back training (12 sessions) was implemented by varying the working memory load and the presentation speed. All participants completed a neuropsychological battery of tests before and after the training. On average, younger training participants achieved difficulty level 12 after training, while older training participants only reached difficulty level 5. In younger participants, transfer to Verbal Fluency and Digit Symbol Substitution test was found. In older participants, we observed a transfer to Digit Span Forward, CERAD Delayed Recall, and Digit Symbol Substitution test. Results suggest that working memory training may be a beneficial intervention for maintaining and improving cognitive functioning in old age.
