False consensus in situational judgment tests: What would others do?

We introduce an alternative response instruction to reduce the fakability of situational judgment tests. This novel instruction is based on the false consensus effect, a robust social psychological bias whereby people infer that the majority of other people’s thoughts, attitudes, and behaviors are aligned with their own. In four studies, including both field and laboratory data (total N = 882), we demonstrate that participants show a false consensus bias when asked what others would do in situational judgment tests. Furthermore, the situational judgment test based on the false consensus effect turned out to relatively difficult to be fake, and produced scores that were meaningfully correlated with conceptually related traits, as well as both self-reported and behavioral outcomes.     

Strategic retrieval processing and the impact of knowing when a memory was first created

Retrieval orientation refers to a process where participants strategically alter how a memory cue is processed in response to different task demands. In the present study we explored whether retrieval orientation is influenced by knowing when an old stimulus was first encoded. Participants completed separate remember/know test blocks for old items from a recent delay (40 min) and old items from a remote delay (48 h). Manipulations at encoding ensured that performance levels were matched between these two blocks, thus avoiding confounds with differences in retrieval effort. Importantly, a third test block comprised old items from both delays randomly intermixed. As the nature of the old items varies unpredictably in the mixed block, it should not be possibly to adopt a specific retrieval orientation and the mixed block therefore acts as a control condition. Participants saw the words “mixed,” “recent” or “remote” prior to each test block. Comparing ERPs from the recent and remote blocks permitted an investigation of whether participants alter their retrieval orientation in response to the specific length of the retention interval. Comparing ERPs from the pure (recent and remote) test blocks to ERPs from the mixed block permitted an investigation of whether delay information per se led to differences in retrieval strategy. Analysis of the ERP data found no differences between the recent and remote blocks. However, ERPs from these pure blocks were significantly less positive than ERPs from the mixed block from 200 ms towards the end of the epoch. The findings suggest that the delay information was useful in a general sense and encouraged retrieval strategies distinct from those engaged in the mixed block. We speculate that such strategies might relate to whether or not the retrieval search is specific and constrained and/or whether processes that serve to reinstate the original encoding context are engaged.     

A meta-analysis of correlations between depression and first person singular pronoun use

Depression is a burden. We discuss how theories, identification, assessment, and treatment of depression are at least partially tied to the correlation between first person singular pronoun use and individual differences in depression. We conducted a meta-analysis (k = 21, N = 3758) of these correlations, including numerous unpublished correlations from the file drawer. Our fixed effects analysis revealed a small correlation (r = 0.13, 95% CI = [0.10–0.16]) by modern standards. The correlation was not moderated by gender, nor by whether the effect had been published. These results more firmly establish first person singular pronoun use as a linguistic marker of depression—a marker that appears to be useful across demographic lines.     

Effets du bilinguisme précoce sur la flexibilité représentationnelle et procédurale dans le dessin du bonhomme

The present research aims to evaluate representational and procedural flexibility by comparing the performances of simultaneous bilingual children French-Arabic (n = 28), successive bilingual children Tamil-French (n = 21) and French monolinguals (n = 24) at 5 years old and at 8 years old educated, in public school, in a disadvantaged neighborhood. The paradigm of the man that does not exist (Karmiloff-Smith, 1990) has been proposed to measure the ability to introduce graphic innovation into a familiar production and drawing a man by starting with the foot (Baldy, 2010) was used to evaluate the ability to make an usual pattern in an unusual way. The results show that bilingual children as young as 5 years old produce significantly more inter-categorical innovations than their monolingual peers while in monolingual children this capacity doesn’t appear until 8 years old. In procedural representations, the results are more nuanced. The underlying mechanisms that explain the best performance of bilingual children are discussed.     

No evidence of attentional bias in obsessive compulsive checking on the dot probe paradigm

Attentional biases have been proposed as maintaining and causal factors in anxiety, and it has been suggested that training attentional bias can impact on emotional responding. Given the severity of obsessive compulsive disorder (OCD) and the considerable number of clients who do not respond to traditional therapies, understanding the factors that maintain anxiety in OCD is critical for the development of effective treatments. This study investigated attentional biases in a homogenous group of OCD patients whose primary concern was checking (OCD-Check; n = 18) compared to a Control group individually matched for age, gender and level of education (Control; n = 18) using a dot probe task. No evidence of attentional bias, or of differences in orienting to or disengaging from checking-relevant stimuli, was found in the OCD group compared to the matched Control group. From this data, it would appear that attentional bias may not be a feature of obsessive compulsive checking. The limitations of the present study and future research directions are discussed.     

Emotional intelligence and risky driving behaviour in adults

BackgroundRisky driving is considered a key predictive factor in road traffic accidents resulting in morbidity and mortality. Intra-individual emotional and personality factors have been shown to influence risk-taking behaviours among drivers. Despite this, there is limited research investigating the individual dimensions of these constructs and their relationship to risky driving behaviour (RDB). The current study therefore aimed to assess whether the individual dimensions of Emotional Intelligence (EI) were implicated in RDB.MethodsThe sample comprised 179 adults (55% male) aged between 18 and 64 years (M = 29.85, SD = 11.46) and who currently held a valid driver’s licence completed an online survey. Emotional Intelligence was assessed via self-report using the Swinburne University Emotional Intelligence Test (SUEIT), and RDB was measured using both the Brief Distracted Driving Scale (BDDS) and the Dula Dangerous Driving Index (DDDI).ResultsRegression analyses revealed that ‘Risky Driving’ was related to greater levels of Emotional Recognition and Expression and lesser Age [F_{(6, 172)} = 2.27, p < 0.05: R² = 7.3%], and the Negative Emotions sub-scale of DDDI, was significantly predicted by Emotional Control and Age [F_{(6, 172)} = 6.41, p < 0.05: R² = 18.3%]. A mediation model incorporating Age, Emotional Control scores and the Negative Emotions driving behaviour score indicated that a significant indirect effect of Age through Emotional Control (K² = 0.08, 95% CI [−0.02, −0.03]). (H [3] = 10.98, p = 0.012).ConclusionsLower scores on specific indices of EI are associated with increased rates of RDB, suggesting that poor emotional control may impede an individuals’ ability to make safe behavioural decisions when driving. The effect sizes for these models were small, however, and further research is needed to explore the contributory components in this association. Greater awareness of the role of emotional regulation and driving behaviours may be useful in preventing RDB in adults.     

The relationship between hip,knee and ankle muscle mechanical characteristics and gait transition speed

The purpose of the present study was to explore the relationship between mechanical characteristics of hip, knee and ankle extensor and flexor muscle groups and gait transition speed. The sample included 29 physically active male adults homogenized regarding their anthropometric dimensions. Isokinetic and isometric leg muscle mechanical characteristics were assessed by an isokinetic dynamometer, while individual walk-to-run (WRT) and run-to-walk transition speeds (RWT) were determined using the standard increment protocol. The relationship between transition speeds and mechanical variables scaled to body size was determined using Pearson correlation and stepwise linear regression. The highest correlations were found for isokinetic power of ankle dorsal flexors and WRT (r = .468, p < .01) and the power of hip extensors and RWT (r = .442, p < .05). These variables were also the best predictors of WRT and RWT revealing approximately 20% of explained variance. Under the isometric conditions, the maximal force and rate of force development of hip flexors and ankle plantar flexors were moderately related with WRT and RWT (ranged from r = .340 to .427). The only knee muscle mechanical variable that correlated with WRT was low velocity knee flexor torque (r = .366, p < .05). The results generally suggest that the muscle mechanical properties, such as the power of ankle dorsal flexors and hip extensors, influence values of WRT and RWT.     

Cognitive Load Undermines Thought Suppression in Acute Stress Disorder

Thought suppression studies demonstrate that attempts to suppress can be undermined by cognitive load. We report the first instance in which this has been tested experimentally in a sample of recently traumatized individuals. Individuals with and without acute stress disorder (ASD) were recruited following recent trauma and randomized to load or no load conditions (N = 56). They monitored intrusive memories during baseline, suppression, and think anything phases. The impact of suppression and load on self-reported intrusions, attention bias (dot-probe), and memory priming (word-stem task) was assessed. The ASD load group were less able to suppress memories (d = 0.32, CI₉₅ [− 0.15, 0.83], p = .088) than the ASD no load group (d = 0.63, CI₉₅ [0.08, 1.24], p < .001). In the think anything phase, the ASD load group reported more intrusions than the ASD no load or non-ASD groups (with and without load). No consistent findings were observed in relation to attentional bias. ASD load individuals exhibited stronger priming responses for motor vehicle accident and assault words than all other groups (ds between 0.35–0.73). Working memory did not moderate any outcomes of interest. The findings indicate that cognitive load interferes with suppression and may enhance access to trauma memories and associated material. The study extends previous research by demonstrating these effects for the first time in a clinical sample of recent survivors of trauma.     

Psychophysical thresholds of face visibility during infancy

The ability to detect and focus on faces is a fundamental prerequisite for developing social skills. But how well can infants detect faces? Here, we address this question by studying the minimum duration at which faces must appear to trigger a behavioral response in infants. We used a preferential looking method in conjunction with masking and brief presentations (300 ms and below) to establish the temporal thresholds of visibility at different stages of development. We found that 5 and 10 month-old infants have remarkably similar visibility thresholds about three times higher than those of adults. By contrast, 15 month-olds not only revealed adult-like thresholds, but also improved their performance through memory-based strategies. Our results imply that the development of face visibility follows a non-linear course and is determined by a radical improvement occurring between 10 and 15 months.     

Cyclic variations in sustained human performance

Biological rhythms play a prominent role in the modulation of human physiology and behavior. [Smith, K., Valentino, D., & Arruda, J. (2003). Rhythmic oscillations in the performance of a sustained attention task. Journal of Clinical and Experimental Neuropsychology, 25, 561-570] suggested that sustained human performance may systematically fluctuate in a cyclic manner with periods of 1.5 min and 5.2 min. The current series of investigations sought to manipulate those periodicities by altering task difficulty, administering caffeine, and testing on a more ecologically valid task. Strong evidence of a 1.5 min periodicity was found across studies. Most participants did not demonstrate the 5.2 min periodicity. Moreover, the 1.5 min periodicity was resistant to task manipulations and appeared in similar levels across conditions in all three experiments. These rhythms may be indicative of an endogenous system that modulates sustained attention in humans. Evidence supporting this idea and implications of the research are discussed.     

Assessment of Person-Centered Care in Gerontology Services: A new tool for healthcare professionals

Background/Objective: Retirement homes and other gerontology services are frequently criticized due to their lack of flexibility and tailored attention, leading to homogeneous treatment which compromises patients’ control of their lives. This study aims to develop and validate the first Spanish instrument for healthcare professionals to assess the degree of person-centered attention delivered by senior care centers. Method: A total of 844 healthcare professionals (mean age = 39.94 years old; SD = 10.56) with a mean of 6.56 years (SD = 6.15) of work experience participated in the study. The psychometric properties of the questionnaire developed were analyzed using both classical test theory and item response theory models. Results: The internal structure was unidimensional with an explained variance of 55.23%. Reliability was outstanding: internal consistency (α = .96, ω = .96) and test-retest (r = .88; ICC = .93). The total score was significantly correlated with two similar questionnaires, with associated variance of 58.83% and 55.20% respectively. Conclusions: The new instrument allows healthcare professionals to assess the level of person-centered care provided by gerontology centers with excellent reliability and validity.     

Motivational Text Message Intervention for Eating Disorders: A Single-Case Alternating Treatment Design Using Ecological Momentary Assessment

ObjectiveThis study tested a motivational text message treatment adjunct for individuals with eating disorders (EDs) who exhibited high dietary restraint/restriction. Method: A replicated single-case alternating treatment design was used to examine (a) the feasibility of combining a brief motivational interview with subsequent text messages and (b) the influence of the text messages on eating behaviors and motivation to change in individuals with EDs (N = 12). The protocol was 8 weeks and the text messages were adjunctive to cognitive-behavioral therapy. Results: The intervention was well accepted (mean rating = 7/10) and feasible within the context of monetary compensation (mean daily monitoring compliance = 91%). Text messages did not impact behavioral outcomes: dietary restraint and kilocalorie intake. They had mixed effects on motivation to change dietary restraint, measured by the Readiness and Motivation Questionnaire (RMQ). When receiving text messages, RMQ precontemplation scores (desire to restrict) significantly increased, indicating decreased motivation; however, action scores (effort toward reducing dietary restraint) significantly increased, indicating increased motivation. These effects were moderated by weight status. Underweight individuals (n = 4; body mass index [BMI] < 19.0) reported increased ambivalence—that is, an increased desire to restrict and increased action toward reducing restriction—in response to the text messages. Normal weight participants (n = 8; BMI > 19.0) reported only increased action toward reducing restriction in response to the text messages. Discussion: These data demonstrate text messages are a potentially feasible and acceptable treatment adjunct and may be effective at increasing motivation to change for normal weight individuals, while their influence on underweight patients is more complex. These findings provide a foundation for future research in technology-based motivational interventions for EDs and offer preliminary evidence for using these methods among normal weight individuals.     

Less is not always more: The case of the 36-item short form of the Zimbardo Time Perspective Inventory

Recently, a shortened version of the Zimbardo Time Perspective Inventory (ZPTI; Zimbardo & Boyd, 1999) was proposed as a “gold standard” (Sircova et al., 2014, p. 9). In this study, we examined the internal consistency and structural validity of this version of the ZPTI in samples of adolescents from the United Kingdom (N = 913) and the United States (N = 815), and adults from Australia (N = 667). Results provided support for the internal consistency of ZPTI scores, but structural validity analyses indicated poor fit and numerous problematic items. The findings call into question the use of scores on this shortened version of the ZTPI.     

Inbreeding depression and IQ in a study of 72 countries

In this ecological study, a robust negative correlation of r = ? .62 (P < .01) is reported between national IQs and consanguinity as measured by the log₁₀ transformed percentage of consanguineous marriages for 72 countries. This correlation is reduced in magnitude, when IQ is controlled for GDP per capita (r = ? .41, P < .01); education index (r = ? .40, P < .01); and democracy index (r = ? .42, P < .01). Multiple regression analysis revealed that in the absence of the democracy index; percentage consanguineous marriages, education index and GDP per capita all exhibited stable final standardized β coefficients, however consanguinity had the least impact (β = 0, P > .05) whereas GDP per capita had the highest (β = .35, P > .01). This result is interpreted in light of cultural feedback theory, whereby it is suggested that consanguinity could subtly influence IQ at larger scales as a result of small IQ handicaps bought about through inbreeding being amplified into much larger differences through their effect on factors that maximize IQ such as access to education and adequate nutrition. Finally, consideration is given to future potential research directions.     

Finger counting habit and spatial–numerical association in children and adults

Sensory-motor experiences are known to build up concrete and abstract concepts during the lifespan. The present study aimed to test how finger counting habits (right-hand vs. left-hand starters) could influence the spatial–numerical representation in number-to-position (explicit) and digit-string bisection (implicit) tasks. The subjects were Italian primary school children (N = 184, from the first to the fifth year) and adults (N = 42). No general preference for right- or left-starting in the finger counting was found. In the explicit task, right- or left-starting did not affect performance. In the implicit task, the right-hand starters shifted from the left to the right space when bisecting small and large numbers respectively, while the left-hand starters shifted from the right to the left space with higher leftward bias for large numbers. The finger configuration in Italian children and adults influences the spatial–numerical representation, but only when implicit number processing is required by the task.     

Trajectories of self-evaluation bias in primary and secondary school: Parental antecedents and academic consequences

Using a longitudinal approach spanning nine years of children's formal education, this study investigated the developmental trajectories of self-evaluation bias of academic competence. The study also examined how parenting styles were associated with the trajectories of bias in mid-primary school, and how those trajectories predicted academic outcomes at the end of secondary school and the beginning of college. A total of 711 children in 4th and 5th grades (mean age = 10.71 years old; 358 girls) participated in this study. Using a latent class growth modeling framework, results indicated that children can be classified in three latent growth trajectories of self-evaluation bias: the optimistic, realistic and pessimistic trajectories. These trajectories differed in their initial status of bias and also in their development over time. Children's adherence to a specific trajectory was associated with parenting variables in childhood. Finally, the optimistic, realistic, or pessimistic trajectories distinctively predicted achievement and persistence.     

Propulsion strategy in the gait of primary school children; the effect of age and speed

The strategy used to generate power for forward propulsion in walking and running has recently been highlighted as a marker of gait maturation and elastic energy recycling. This study investigated ankle and hip power generation as a propulsion strategy (PS) during the late stance/early swing phases of walking and running in typically developing (TD) children (15: six to nine years; 17: nine to 13 years) using three-dimensional gait analysis. Peak ankle power generation at push-off (peakA2), peak hip power generation in early swing (peakH3) and propulsion strategy (PS) [peakA2/(peakA2 + peakH3)] were calculated to provide the relative contribution of ankle power to total propulsion. Mean PS values decreased as speed increased for comfortable walking (p < 0.001), fast walking (p < 0.001) and fast running (p < 0.001), and less consistently during jogging (p = 0.054). PS varied with age (p < 0.001) only during fast walking. At any speed of fast walking, older children generated more peakA2 (p = 0.001) and less peakH3 (p = 0.001) than younger children. While the kinetics of running propulsion appear to be developed by age six years, the skills of fast walking appeared to require additional neuromuscular maturity. These findings support the concept that running is a skill that matures early for TD children.     

Malleability of weight-biased attitudes and beliefs: A meta-analysis of weight bias reduction interventions

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.     

Advanced age brings a greater reliance on visual feedback to maintain balance during walking

We implemented a virtual reality system to quantify differences in the use of visual feedback to maintain balance during walking between healthy young (n = 12, mean age: 24 years) and healthy old (n = 11, 71 years) adults. Subjects walked on a treadmill while watching a speed-matched, virtual hallway with and without mediolateral visual perturbations. A motion capture system tracked center of mass (CoM) motion and foot kinematics. Spectral analysis, detrended fluctuation analysis, and local divergence exponents quantified old and young adults’ dynamic response to visual perturbations. Old and young adults walked normally with comparable CoM spectral characteristics, lateral step placement temporal persistence, and local divergence exponents. Perturbed visual flow induced significantly larger changes in mediolateral CoM motion in old vs. young adults. Moreover, visual perturbations disrupted the control of lateral step placement and compromised local dynamic stability more significantly in old than young adults. Advanced age induces a greater reliance on visual feedback to maintain balance during waking, an effect that may compensate for degradations in somatosensation. Our findings are relevant to the early diagnosis of sensory-induced balance impairments and also point to the potential use of virtual reality to evaluate sensory rehabilitation and balance training programs for old adults.     

Representations of guidance counselors,psychologists, and psychoeducators regarding psychological assessment

IntroductionSocial representations related to collaborative/therapeutic and information-gathering assessment could explain some psychological assessment practices. However, no other study has attempted to examine the actual place of these models in psychological assessment practices.ObjectiveThe goal of this study was to examine the social representations of different groups of professionals with regard to their preferred approach to psychological assessment.MethodA latent profile analysis was conducted on a sample of licensed Canadian guidance counselors (n = 382), psychologists (n = 235), and psychoeducators (n = 97).ResultsResults revealed three psychological assessment profiles, which significantly differ in terms of a few social factors. Results also showed that some psychological assessment practices differ across profiles.ConclusionThis study provides a better understanding of psychometric instruments users’ approaches to assessment and the influence of social factors.
