Understanding boundary extension: Normalization and extension errors in picture memory among adults and boys with and without Asperger's syndrome

Boundary extension is the tendency for people to “remember” information that fell outside a picture's boundaries. We used a novel test of boundary extension to provide absolute estimates of the magnitude of extension errors and of the degree to which people are influenced by the way a picture is presented at the time of testing. Participants were shown photographs on a computer and subsequently allowed to adjust their magnification to match the size they remembered. The test produced reliable boundary extension of around 11% in adults and large influences of initial test size. In a second experiment we tested boys diagnosed with Asperger's syndrome and matched controls. Both groups demonstrated boundary extension comparable to that observed in adults but greater effects of initial test size. High performance IQ in Asperger's was linked with high levels of boundary extension, while for the matched control group the opposite pattern was obtained.     

Laypeople do use sample variance: The effect of embedding data in a variance-implying story

When using sample data to decide whether two populations differ, laypeople attend to the difference between group means, but largely overlook within-group variability (Obrecht, Chapman, & Gelman, 2007 Obrecht, N. A., Chapman, G. B. and Gelman, R. 2007. Intuitive t-tests: Lay use of statistical information. Psychonomic Bulletin & Review, 14: 1147–1152.  [Google Scholar]). We show, first, that laypeople know about and use story-implied variability when making pairwise comparisons. Then we demonstrate that participants’ sensitivity to variance in a dataset is boosted when presented in a context that implies consistent variance information. Statistical data were couched in stories about electrical conductivity measurements obtained from element samples (low-variability category) or body weight measurements from samples of peoples (high-variability category). We manipulated, between participants, whether the data variance matched or mismatched the story-implied variability. Participants who received data in a matching context showed high sensitivity to variance, while those in the mismatching condition did not. Laypeople use statistical data to make reasonable inferences when those data are provided in a context that makes sense.     

Enhanced memory for emotional pictures: A product of increased attention to affective stimuli?

The current experiment addressed the question, is enhanced memory for emotional pictures due to increased attention to affective stimuli? Participants viewed pairs of pictures (emotional-neutral or neutral-neutral) whilst their eye movements were recorded; participants had to decide which picture out of each pair they preferred. There was increased attention to positive pictures and decreased attention to negative images during picture viewing. Despite this, when a recognition test was given 1 week later, memory enhancements were found for negative pictures only. Moreover, although there was a general correlation between total inspection time and memory performance, this reliability was clear only for neutral pictures, and not for emotional images. The results suggest that memory advantages for emotional pictures can occur without increased attention to such images.     

Using an Imagery Intervention to Train Visual Exploratory Activity in Elite Academy Football Players

Football players adapt their movements to opportunities within the surrounding environment by engaging in visual exploratory activity (VEA) to pick up information. This study adds to the extant literature by using a 6-week PETTLEP imagery intervention to train VEA and improve performance with the ball. A single-case, multiple baseline across participants' design was conducted with 5 elite academy football players. Results indicated that a PETTLEP imagery intervention improved VEA, particularly in center midfielders. In addition, indications of improvements in performance with the ball were present within some participants. Future researchers could examine the processes underpinning VEA to enhance applied interventions for this skill.     

Understanding smoking after acute illness: An application of the sentinel event method

The sentinel event theory provides a stepwise approach for building models to understand how negative events can spark health behaviour change. This study tested a preliminary model using the sentinel events method in a sample (N = 300) of smokers who sought care for acute cardiac symptoms. Patients completed measures on: smoking-related causal attribution, perceived severity of the acute illness event, illness-related fear and intentions to quit smoking. Patients were followed up one week after the health event and a seven-day timeline follow back was completed to determine abstinence from tobacco. Structural equation models were performed using average predictor scale scores at baseline, as well as three different time anchors for ratings of illness severity and illness-related fear. Quit intentions, actual illness severity and age were the consistent, positive and independent predictors of seven-day point prevalence abstinence. Additional research on the influences of perceptions and emotional reactions is warranted.     

Sex,Power, and Money: Prediction from the Dark Triad and Honesty–Humility

Data were collected from two undergraduate student samples to examine (i) the relations of the ‘Dark Triad’ variables (Machiavellianism, Psychopathy, and Narcissism) with the HEXACO personality dimensions, as well as (ii) the ability of the aforementioned characteristics and of the Big Five personality factors to predict outcome variables related to sex, power, and money. Results indicated that the common variance of the Dark Triad was very highly correlated with low Honesty–Humility and that the unique variance of each of the Dark Triad variables also showed theoretically meaningful relations with the other five HEXACO factors. Furthermore, the Dark Triad and Honesty–Humility were strong predictors of three domains of outcome variables—Sex (short‐term mating tendencies and sexual quid pro quos), Power (Social Dominance Orientation and desire for power), and Money (conspicuous consumption and materialism)—that were not well predicted by the dimensions of the Big Five.

Making our Measures Match Perceptions: Do Severity and Type Matter When Assessing Academic Misconduct Offenses?

Traditional approaches to measurement of violations of academic integrity may overestimate the magnitude and severity of cheating and confound panic with planned cheating. Differences in the severity and level of premeditation of academic integrity violations have largely been unexamined. Results of a study based on a combined sample of business students showed that students are more likely to commit minor cheating offenses and engage in panic-based cheating as compared to serious and planned cheating offenses. Results also indicated there is a significant interaction between severity and type (planned vs. panic) of cheating. We hypothesized serious and planned cheating offenses would be related to justifications and found the largest differences were between panic and planned. Finally, panic and minor cheating were associated with two self-control-related personality traits. Implications for cheating research are discussed.     

Honesty-Humility and Perceptions of Organizational Politics in Predicting Workplace Outcomes

Purpose

The present study sought to examine whether a personality dimension named Honesty-Humility influences the relationship between employees’ perceptions of organizational politics (POP) and workplace outcomes, both attitudinal and behavioral.

Design/Methodology/Approach

Data were collected online and cross-nationally from 268 full-time employees from various organizations and occupational backgrounds.

Findings

Results indicate that the adverse effect of POP in the workplace is exacerbated for employees who are lower (rather than higher) in Honesty-Humility. Specifically, when perceiving their workplace as political, low Honesty-Humility individuals were more likely to engage in counterproductive work behavior and impression management behavior and to experience greater job stress and decreased job satisfaction.

Implications

Examining the role of individual differences in POP helps to advance our understanding of the mechanisms that employees use to interpret and react within a perceived politically charged workplace. This study provides further evidence of the deleterious effects of POP in the workplace, especially among low Honesty-Humility individuals. Practical implications of this research focus on reducing the likelihood of hiring low Honesty-Humility individuals as well as on reducing the opportunity for undesirable behaviors among currently employed individuals.

Originality/Value

There is a paucity of research exploring the possibility that individuals may react differently from one another to POP within their workplace and, in turn, experience varying outcomes. The present study helps to fill this gap in the literature by providing novel insights as to the role of personality in predicting perceptions of, and reactions to, organizational politics.
