Search

Purpose: Previous research has repeatedly shown that people only search for files in a small minority of cases when they do not remember the file's location. The current study aimed to examine whether there is a group of hyper-searchers who search significantly more than others. Based on previous neurocognitive studies, this study aims to hypothesize that if such a group exists, they will have superior verbal memory and reduced visuospatial memory. Design/methodology/approach: In total, 65 participants completed a questionnaire estimating their search percentages, as well as reporting demographic data. Verbal memory was measured using the Wechsler logical memory test, and visuospatial memory was assessed using an online card memory game. Findings: Hyper-searchers were defined as participants with search percentage of over one standard deviation (SD) above the mean. The average search percentage of the seven participants who met this criterion was 51% (SD = 14%), over five times more than the other participants (M = 10%, SD = 9%). Similar results were obtained by re-analyzing data from four previous papers (N = 1,252). The results further confirmed the hypothesis that hyper-searchers have significantly better verbal memory than other participants, possibly making searching easier and more successful for them. Lastly, the search percentage was positively predicted by verbal memory scores and negatively predicted by visuospatial memory scores. Explanations and future research are discussed. Originality/value: This preliminary study is the first to introduce the concept of hyper-searchers, demonstrate its existence and study its causes.

© 2020 Elsevier Inc. We investigate whether the tendency to self-affirm in response to threat is associated with how people feel when they weigh themselves. People who were preoccupied with their weight anticipated feeling less negative (Studies 1a and 1b) and felt less negative (Study 2) when self-weighing if they typically affirmed their strengths. Study 3 experimentally manipulated self-affirmation. Although this intervention prompted affirmation of strengths it did not influence how participants felt when they subsequently weighed themselves. Together, the findings suggest that the tendency to spontaneously affirm strengths, but not values or social relations, is associated with the psychological outcomes of self-weighing and thus provide the basis for understanding how such individual differences might moderate how people respond in other self-evaluative contexts.

Objectives: Skin cancer is a growing problem globally. Older men have been largely ignored in previous research, even though men may generally be prone to riskier exposure to the sun than women. Past research suggests that appearance-focused techniques such as facial morphing can increase motivations to use sun protection among women of all ages, and younger men. Design: was qualitative, consisting of individual interviews. Method: was semi-structured interviews with 25 older men, to examine attitudes to UV exposure and reactions to a facial morphing intervention. Interviews were subjected to thematic analysis. Results: Three themes were constructed: masculine UV exposure; appearance that’s accepted; personal responsibility. The men did not identify gaps in their sun protection behaviour, and demonstrated a lack of concern about ageing and appearance. These attitudes translated into a lack of motivation for behaviour change due to ageing acceptance. However, motivation to change behaviour came from health concerns resulting from the intervention. Conclusions: The men experienced different motivations and barriers for sun protection use than women of similar ages. Facial morphing can be effective with older men, but may need to be reframed to focus on health implications and personal choice.

As a majority of skin cancer cases are behaviourally preventable, it is crucial to develop effective strategies to reduce UV exposure. Health-focused interventions have not proved to be sufficiently effective, and it has been suggested that people might be more susceptible to information about the negative effects of the sun on their appearance. Method: This systematic review of 30 separate papers, reporting 33 individual studies published between 2005 and 2017 assesses the overall effectiveness of appearance interventions on participants’ UV exposure and sun protection behaviour. Results: Appearance-based interventions have positive effects on sun exposure and sun protection, immediately after the intervention as well as up to 12 months afterwards. The meta-analysis found a medium effect size on sun protection intentions for interventions which combined UV photography and photoaging information: r+ = .424; k = 3, N =319, CI = .279 - .568, p = .023. Conclusions: We provide a review of current research on the effectiveness of appearance-based interventions to reduce UV exposure. As well as highlighting methodological issues we recommend that practitioners administer a UV photo intervention in combination with photo-aging information to reduce UV exposure. Furthermore, the review specifically recommends that future research focuses on the use of theoretical constructs to enhance photoaging information, and is conducted with older participants and in countries where people have less opportunity for sun exposure.

When do people check the balance of their personal bank accounts? To investigate this issue, we examined whether the monitoring of personal finances is influenced by peoples’ perceptions of their progress toward financial goals and their regulatory focus (i.e., whether the goal involves attaining a positive outcome or avoiding a negative outcome). Study 1 examined how often participants logged into their online bank accounts to check their balance and found that the worse they perceived their progress toward their most important financial goal to be, the more often they checked. In Studies 2 and 3 we developed a simulation of personal financial management in which participants were given financial goals that involved attaining a positive outcome and avoiding a negative outcome. Goal progress was manipulated via the balance in participants’ account at the start of the simulation (Studies 2 and 3) and the rate at which their balance increased (Study 3). Participants in Study 2 checked their balance more often when they perceived their progress toward financial goals to be poor and when they considered avoiding the negative outcome to be important. In Study 3, the frequency with which participants checked their balance was influenced by an interaction between goal progress, the regulatory focus of the goal, and the importance of the goal. Participants who felt that gaining money was relatively important were more likely to check their balance when their progress was good, whereas participants who felt that avoiding losing money was relatively important were more likely to check their balance when progress was both good and bad. Taken together, these findings contribute to our understanding of how people manage their personal finances, and self-regulation more generally, by revealing that how often people monitor their personal finances depends on perceptions of goal progress, regulatory focus, and the importance of the goal.

Skin cancer is to a large degree behaviourally preventable, meaning that evidence-based interventions have scope to make a difference. Previous research indicates that appearance-based interventions such as facial morphing may be more effective than health-based interventions, and that it can personalise the issue of skin cancer.This study examined attitudes to UV exposure, as well as reactions to a facial morphing intervention, through interviews with 25 women aged 35 years and older.Thematic analysis revealed four themes; two regarding attitudes to UV exposure (confusion and contradiction, and change and continuity), and two relating to the facial morphing intervention (negative reactions to UV-exposed photo and positive outcomes of the intervention). Women experienced a number of barriers to adopting safer behaviour in the sun; their current attitudes to UV exposure had been shaped by available information sources throughout their ageing. They expressed negative evaluations of the UV photo, which fed directly into motivation to reduce UV exposure.These results can be interpreted along the lines of goal-directed behaviour. This type of intervention has the potential to reduce UV exposure among this participant group, something that needs to be further investigated with randomised control trials.

© 2017 Chang, Webb, Benn and Stride. Three studies examined how people assess their progress on personal goals (e.g., whether they compare their progress to the past and/or to a desired target state), along with factors that might influence the nature of progress monitoring (e.g., whether the goal involves attaining a positive outcome or avoiding a negative outcome). Study 1 involved semi-structured interviews with 40 participants, in which we examined how participants monitored their progress and whether this was related to: (a) their level of self-efficacy, (b) whether the goal was prevention focused, and (c) whether goal progress was represented in quantifiable terms. Studies 2 (N = 492) and 3 (N = 481) were conducted online and additionally examined whether how participants monitored their progress differed as a function of the domain of the goal (i.e., whether it was related to physical development/health, finances, work/study, or social relationships). The findings suggest that participants: (i) were less likely to monitor their progress toward goals that were related to avoiding negative outcomes, (ii) were less likely to monitor their progress toward goals related to finances, work, or study with reference to the past, than progress toward other goals (e.g., those relating to physical development and health), (iii) found it easier to monitor their progress toward goals that they felt confident of attaining, but harder to monitor their progress toward goals related to work or study. Finally, the more participants thought about their goal in quantifiable terms, the more likely they were to monitor their progress, and the easier they found monitoring their progress to be. Taken together, these studies begin to describe the nature of progress monitoring and the factors that influence this important self-regulatory process.

Two studies examined peoples' reasons for not monitoring their progress toward their personal goals—a phenomenon that has been termed “the ostrich problem” (Webb et al., 2013). Study 1 used factor analysis to organize the reasons that people gave for not monitoring their goal progress, resulting in 10 factors. The most strongly endorsed reasons were: (a) that information on goal progress would demand a change in beliefs, or (b) undesired action; (c) that progress was poor, and (d) that thinking about and/or working on the goal was associated with negative emotions. Study 2 adopted a prospective design and investigated whether the reasons identified in Study 1 predicted: (a) the likelihood that participants would decline an opportunity to monitor their goal progress, and (b) the frequency with which participants monitored their goal progress. We found evidence that some of the most strongly endorsed reasons from Study 1 also predicted the avoidance of monitoring in Study 2; however, the belief that information about goal progress was likely to be inaccurate and not useful, and perceived control over goal attainment also reliably predicted the avoidance of monitoring in Study 2. Taken together, the findings explain why people do not monitor their goal progress and point to potential avenues for intervention.

ABSTRACT: Many people self-weigh and many interventions addressing weight-related problems such as obesity promote self-weighing. However, while self-weighing has been associated with weight loss, there is mixed evidence regarding the psychological impact of this behaviour. The present review aimed to quantify the relationship between self-weighing and: (i) affect (e.g., anxiety, depression); (ii) psychological functioning (e.g., self-esteem); (iii) body-related attitudes and (iv) disordered eating. A computerized search of scientific databases in September 2014 and subsequent ancestry and citation searches identified 29 independent tests of the relationship between self-weighing on psychological outcomes. Meta-analysis was used to quantify the size of the association across the tests. Results indicated that there was no association between self-weighing and affect, body-related attitudes or disordered eating. There was, however, a small-sized negative association between self-weighing and psychological functioning. The age of participants, obesity status, the extent of weight loss, duration of self-weighing and study design (RCT versus correlational) were found to influence at least some of the psychological outcomes of self-weighing. The findings suggest that, for the most part, self-weighing is not associated with adverse psychological outcomes. However, in some cases the association between self-weighing and psychological outcomes may be more negative than in others.

© 2015 The Authors. Previous research investigating what information shoppers seek when purchasing groceries has used either lab-experiments or observed shoppers in supermarkets. The present research investigates this question in a relatively naturalistic online-grocery environment. Forty participants completed their weekly shopping online while their eye-movements were recorded. Ten of the participants were subsequently interviewed to gain insight into their information seeking behaviour. We found that, when looking for products, 95% of participants navigated through the 'virtual departments', 80% used the 'search' facility, and 68% browsed the special offer pages. Once on the product pages, participants tended to look at the pictures of products, rather than examine detailed product information. To explain these findings, we suggest that online grocery sites simulate familiar supermarket environments, which may explain why consumers prefer to browse categories of products rather than use search terms. We also suggest that additional strategies are needed if consumers are to be encouraged to view detailed product information.

Efficient storage and retrieval of digital data is the focus of much commercial and academic attention. With personal computers, there are two main ways to retrieve files: hierarchical navigation and query-based search. In navigation, users move down their virtual folder hierarchy until they reach the folder in which the target item is stored. When searching, users first generate a query specifying some property of the target file (e.g., a word it contains), and then select the relevant file when the search engine returns a set of results. Despite advances in search technology, users prefer retrieving files using virtual folder navigation, rather than the more flexible query-based search. Using fMRI we provide an explanation for this phenomenon by demonstrating that folder navigation results in activation of the posterior limbic (including the retrosplenial cortex) and parahippocampal regions similar to that previously observed during real-world navigation in both animals and humans. In contrast, search activates the left inferior frontal gyrus, commonly observed in linguistic processing. We suggest that the preference for navigation may be due to the triggering of automatic object finding routines and lower dependence on linguistic processing. We conclude with suggestions for future computer systems design.

This Evidence Check review examined the effectiveness of specific behaviour change techniques (BCTs) delivered by telephone in two areas: promoting healthy weight; and supporting parents. The review found that telephone-delivered interventions to promote healthy weight can be effectively used to change physical activity levels and improve diet. Interventions designed to support parents have been shown to improve both children’s behaviour and parents’ wellbeing. None of the included studies identified specific tools to determine which BCTs should be employed and when. The authors recommend the systematic use of theory to identify behavioural determinants and select the most effective BCT.

Item does not contain fulltext, A debated issue in the relationship between language and thought is how our linguistic abilities are involved in understanding the intentions of others ('mentalizing'). The results of both theoretical and empirical work have been used to argue that linguistic, and more specifically, grammatical, abilities are crucial in representing the mental states of others. Here we contribute to this debate by investigating how damage to the language system influences the generation and understanding of intentional communicative behaviors. Four patients with pervasive language difficulties (severe global or agrammatic aphasia) engaged in an experimentally controlled non-verbal communication paradigm, which required signaling and understanding a communicative message. Despite their profound language problems they were able to engage in recipient design as well as intention recognition, showing similar indicators of mentalizing as have been observed in the neurologically healthy population. Our results show that aspects of the ability to communicate remain present even when core capacities of the language system are dysfunctional.
