Emotional responding in NSSI: examinations of appraisals of positive and negative emotional stimuli,with and without acute stress

Non-suicidal self-injury (NSSI) is commonly used by young adults to regulate emotional responses. Yet, experimental examination of how people who self-injure appraise and respond to emotional stimuli is limited. We examined appraisals of, and responses to, emotive images in young adults who did and did not self-injure, and assessed whether these were impacted by exposure to a stressor. Study 1 (N?=?51) examined whether participants differed in their appraisals of emotional images. Study 2 (N?=?78) assessed whether appraisals of images changed after exposure to the Trier Social Stress Test. Ratings of emotional valence and arousal were collected in both studies; skin conductance was measured as an indicator of physiological arousal in Study 2. In Study 1 participants reporting NSSI rated positively valenced images as less pleasant than participants not reporting NSSI. In Study 2, after acute stress, participants reporting NSSI displayed dampened physiological reactions to positive images whereas participants who did not self-injure displayed heightened physiological reactions to these and rated them as more pleasant. Individuals who self-injure seem less able to engage in strategic mood repair after exposure to stress compared to people who do not self-injure.     

Ramón García,Featured Poet: Brother Bluebeard and Other Poems

In this commentary on the “Brother Bluebeard” sequence by featured poet Ramón García, I consider the profound and terrible revelations this mythic poem gives about our own dreaded times, as well as the wisdom it brings us, patterned on the archetype of initiation—descent into an underworld. In his gender-fluid retelling of the Bluebeard legend, the narrator of the poem is a man who sleeps with men, but who over the course of the poem identifies with the women whom Bluebeard has slaughtered. This is at once a highly political sequence of poems, in which we can recognize the Bluebeard in our current national story, a Jungian series of poems that illuminates the alchemical process of mortificatio and rebirth, and a story of trauma and spiritual recovery.     

Comparing Data Sets: Implicit Summaries of the Statistical Properties of Number Sets

Comparing datasets, that is, sets of numbers in context, is a critical skill in higher order cognition. Although much is known about how people compare single numbers, little is known about how number sets are represented and compared. We investigated how subjects compared datasets that varied in their statistical properties, including ratio of means, coefficient of variation, and number of observations, by measuring eye fixations, accuracy, and confidence when assessing differences between number sets. Results indicated that participants implicitly create and compare approximate summary values that include information about mean and variance, with no evidence of explicit calculation. Accuracy and confidence increased, while the number of fixations decreased as sets became more distinct (i.e., as mean ratios increase and variance decreases), demonstrating that the statistical properties of datasets were highly related to comparisons. The discussion includes a model proposing how reasoners summarize and compare datasets within the architecture for approximate number representation.     

Perceptions of Nepotism Beneficiaries: The Hidden Price of Using a Family Connection to Obtain a Job

Purpose

This study tested competing predictions about the impact of nepotistic hiring on perceptions of nepotism beneficiaries, focusing specifically on the performance attributions made about nepotism hires. Of particular interest is how the qualifications of the family member compared to other applicants impacts perceptions of the nepotism hire.

Methodology

Two experimental studies, using scenarios that simulated the hiring process, were conducted. Participants reviewed materials describing the hiring process for a manager and then completed a questionnaire assessing their perceptions of the person hired.

Findings

Results showed that successful performance of nepotism beneficiaries was attributed more to political skills and relationships with upper management and less to ability and effort than was the case for non-beneficiaries and that they were perceived as less competent and as having fewer characteristics of successful managers. These negative perceptions occurred regardless of the family member’s qualifications.

Implications

This study contributes to our understanding of nepotistic hiring practices. More negative performance attributions and perceptions of competence for nepotism beneficiaries may hinder their effectiveness on the job. Knowledge gained from this study may help businesses who want to hire family members of current employees to manage this process more effectively.

Originality/Value

This is one of the first studies to examine the consequences of nepotistic hiring for nepotism beneficiaries and the first study to examine how nepotistic hiring effects the performance attributions made about nepotism beneficiaries. It is also the only study to empirically examine how the qualifications of the nepotism beneficiary influence others’ reactions to them.

     

Do Student Evaluations of University Reflect Inaccurate Beliefs or Actual Experience? A Relative Rank Model

It was shown that student satisfaction ratings are influenced by context in ways that have important theoretical and practical implications. Using questions from the UK's National Student Survey, the study examined whether and how students' expressed satisfaction with issues such as feedback promptness and instructor enthusiasm depends on the context of comparison (such as possibly inaccurate beliefs about the feedback promptness or enthusiasm experienced at other universities) that is evoked. Experiment 1 found strong effects of experimentally provided comparison context—for example, satisfaction with a given feedback time depended on the time's relative position within a context. Experiment 2 used a novel distribution‐elicitation methodology to determine the prior beliefs of individual students about what happens in universities other than their own. It found that these beliefs vary widely and that students' satisfaction was predicted by how they believed their experience ranked within the distribution of others' experiences. A third study found that relative judgement principles also predicted students' intention to complain. An extended model was developed to show that purely rank‐based principles of judgement can account for findings previously attributed to range effects. It was concluded that satisfaction ratings and quality of provision are different quantities, particularly when the implicit context of comparison includes beliefs about provision at other universities. Quality and satisfaction should be assessed separately, with objective measures (such as actual times to feedback), rather than subjective ratings (such as satisfaction with feedback promptness), being used to measure quality wherever practicable. © 2014 The Authors.

Reduced extinction of hippocampal-dependent memories in CPEB knockout mice

CPEB is a sequence-specific RNA binding protein that regulates translation at synapses. In neurons of CPEB knockout mice, synaptic efficacy is reduced. Here, we have performed a battery of behavioral tests and find that relative to wild-type animals, CPEB knockout mice, although similar on many baseline behaviors, have reduced extinction of memories on two hippocampal-dependent tasks. A corresponding microarray analysis reveals that about 0.14% of hippocampal genes have an altered expression in the CPEB knockout mouse. These data suggest that CPEB-dependent local protein synthesis may be an important cellular mechanism underlying extinction of hippocampal-dependent memories.
