Enhanced recognition of memorable pictures in ultra-fast RSVP

Long-term recognition memory for some pictures is consistently better than for others (Isola, Xiao, Parikh, Torralba, & Oliva, IEEE Transaction on Pattern Analysis and Machine Intelligence (PAMI), 36(7), 1469–1482, 2014). Here, we investigated whether pictures found to be memorable in a long-term memory test are also perceived more easily when presented in ultra-rapid RSVP. Participants viewed 6 pictures they had never seen before that were presented for 13 to 360 ms per picture in a rapid serial visual presentation (RSVP) sequence. In half the trials, one of the pictures was a memorable or a nonmemorable picture and perception of this picture was probed by a visual recognition test at the end of the sequence. Recognition for pictures from the memorable set was higher than for those from the nonmemorable set, and this difference increased with increasing duration. Nonmemorable picture recognition was low initially, did not increase until 120 ms, and never caught up with memorable picture recognition performance. Thus, the long-term memorability of an image is associated with initial perceptibility: A picture that is hard to grasp quickly is hard to remember later.     

Predicting staff retention from employee motivation and job satisfaction

This study investigated the role of employee motivation and job satisfaction as predictors of staff retention in a foreign exchange bank. Participants were 341 employees of a South African foreign exchange bank division (female?=?62.8%; black?=?31.1%; managers?=?37%, mean years of experience?=?10 years). The employees completed the following self-report measures: Work Preference Inventory, Job Satisfaction Survey, and Employee Retention Questionnaire. Structural equation modelling was applied in the analysis to test the prediction effect of employee motivation and job satisfaction on staff retention. The findings of the model fit revealed that the model (employee motivation and employee job satisfaction) explained an estimated 46% of the variance in the employee retention construct. The job satisfaction construct in the model explained an estimated 66% of the variance in the employee retention construct; while the employee motivation construct explained only 8% of the variance. Organisational talent management should seek to identify employee motivation and job satisfaction interventions that might help to retain talented staff.     

Feedback type as a moderator of the relationship between achievement goals and feedback reactions

The aim of the current study is to shed new light on the inconsistent relationship between performance‐approach (PAp) goals and feedback reactions by examining feedback type as a moderator. Results of a field experiment (N = 939) using a web‐based work simulation task showed that the effect of achievement‐approach goals was moderated by feedback type. Relative to individuals pursuing mastery‐approach goals, individuals pursuing PAp goals responded more negatively to comparative feedback but not to task‐referenced feedback. In line with the hypothesized mediated moderation model, the interaction between achievement goals and feedback type also indirectly affected task performance through feedback reactions. Providing employees with feedback is a key psychological principle used in a wide range of human resource and performance management instruments (e.g., developmental assessment centres, multi‐source/360° feedback, training, selection, performance appraisal, management education, computer‐adaptive testing, and coaching). The current study suggests that organizations need to strike a balance between encouraging learning and encouraging performance, as too much emphasis on comparative performance (both in goal inducement and in feedback style) may be detrimental to employees' reactions and rate of performance improvement.     

Comparison of corticosterone responses to acute stressors: Chronic jugular vein versus trunk blood samples in mice

A commonly used method for obtaining blood samples from mice is decapitation. However, there is an obvious need for repeated blood sampling in mice under stress-free conditions. Here, we describe a simple technique to repeatedly collect blood samples from conscious, freely moving mice through a chronically implanted jugular vein catheter. Furthermore, we compare plasma corticosterone (CORT) concentrations in samples obtained through the catheter 1 day after surgery with samples taken from trunk blood obtained under basal or acute stress conditions. CORT concentrations in repeated 100-μl venous blood samples were found to be similar to trunk blood samples both under basal conditions and after stressor exposure collected at identical time points (at 5, 15, and 60?min). Using both techniques, we demonstrate a progressive increase in CORT levels until 15?min after termination of stressor exposure and a decrease towards baseline values 60?min later. Anxiety-related behavior, as assessed on the elevated plus maze 3-4 days after surgery, did not differ between catheterized and non-catheterized mice. Our results provide evidence for application of jugular vein catheterization as a technique for repeated blood sampling in conscious laboratory mice. Use of this technique will greatly reduce the number of animals required for experiments involving endocrine endpoints.     

Extinction treatment in multiple contexts attenuates ABC renewal in humans

Renewal has been implicated as one of the underlying mechanisms in return of fear following exposure therapy. ABC renewal is clinically more relevant than ABA renewal and yet it is a weaker form of renewal, suggesting that conducting extinction treatment in multiple contexts may be sufficient to attenuate ABC renewal. Using self-reported expectancy of shock and startle blink responses the current study examined the effects of conducting extinction treatment in multiple contexts on ABC fear renewal. Participants (N = 68) received conditional stimulus (CS) and unconditional stimulus (US) pairings in one context (A) followed by extinction treatment (CS presentations alone) in either one other context (B) or three other contexts (BCD). Non-reinforced test trials in a novel context (E) resulted in renewal of extinguished conditioned behaviour for those who received extinction in only one context. However, renewal was attenuated for those who received extinction treatment in three contexts. No renewal was found for the control group that received the test trial in the same context as during extinction. Suggestions are provided for clinicians seeking to prevent or attenuate return of fear following exposure therapy.     

C'est le Ton Qui Fait la Critique—for the powerful: the effects of feedback framing and power on affective reactions

Although negative feedback is usually provided with the best of intentions, it often causes unfavorable affective reactions in the receiver such as anger and shame. The purpose of the present research is to identify factors that may attenuate or intensify these reactions to negative feedback. We argue and show across a laboratory experiment and a field study that feedback framing may affect feelings of anger and shame, but only for high (vs. low) power individuals. Given the prevalence of power differences in many feedback situations (e.g., in the organizational context), our findings may provide valuable information for the successful provision of negative feedback.     

Differentiating between child protection and family support in the Canadian child welfare system's response to intimate partner violence,corporal punishment,and child neglect

Rates of reported child maltreatment nearly doubled in Canada over the period 1998–2003, an increase that reflects growing awareness of the harmful effects of an expanding array of parental behaviors, including corporal punishment, lack of supervision, and exposure to intimate partner violence (IPV). Some of these situations may benefit from voluntary family support programs outside of the child welfare system. Analyzing a sample of 11,807 investigations, this paper compares cases where the sole concern is exposure to IPV, or hitting a child, or neglect, or other forms of investigated maltreatment. Situations where exposure to IPV or potentially abusive hitting were the sole reason for investigation presented with fewer risk factors and were less likely to lead to ongoing child welfare interventions compared to other maltreatment investigations. While situations involving alleged neglect presented a higher risk profile and elicited a more intensive child welfare response than did exposure to IPV or hitting, opportunities for alternative services were nevertheless identified. The study also found that visible minority families were overrepresented in cases involving hitting and that Aboriginal families were overrepresented in cases involving neglect. Overall the findings support the development of alternative response programs in Canada.
