Effects of facial expression on working memory

In long‐term memory (LTM) emotional content may both enhance and impair memory, however, disagreement remains whether emotional content exerts different effects on the ability to maintain and manipulate information over short intervals. Using a working‐memory (WM) recognition task requiring the monitoring of faces displaying facial expressions of emotion, participants judged each face as identical (target) or not (non‐target) to that presented 2 trials back (2‐back). Negative expression was better and faster recognised, illustrated by higher target discriminability and target detection. Positive and negative expressions also induced a more liberal detection bias compared with neutral. Taking the preceding item into account, additional accuracy impairment (negative preceding negative target) and enhancement effects (negative or positive preceding neutral target) appeared. This illustrates a differential modulation of WM based on the affective tone of the target (mirroring LTM enhancement‐ and recognition bias effects), and of the preceding item (enhanced and impaired target detection).     

To prosecute or not to prosecute: Law students' judicial decisions in CSA cases

Child sexual abuse (CSA) investigations are complicated and few cases are prosecuted. The aim of the present study was to investigate judicial decisions in CSA investigations. Seventy‐one law students (42 females, 29 males) read a vignette depicting a CSA investigation, assessed the complainant's and the accused's credibility, and if the case should be prosecuted or not. The participants were assigned to one of four conditions defined by a 2 (evidence: high probative value vs. low probative value) × 2 (complainant demeanour: emotional vs. neutral) factorial design. Females assigned higher credibility to the complainant than did males and males assigned higher credibility to the accused than did females. Emotionality, but not evidential value, affected credibility judgements: Females believed less in the suspect when the child behaved in an emotional manner. Most participants (94.4%) thought that the case should be prosecuted, though only 73.2% believed that prosecution could be corroborated. Corroboration of prosecution was affected by evidential value, but not emotionality. The results indicate that the behavior of alleged crime victims might affect males and females differently, which in turn could lead to biased judicial decisions in CSA investigations.     

Prevalence of Type D personality and factorial and temporal stability of the DS14 after myocardial infarction in a Swedish population

This study examined the prevalence of Type D personality and the temporal stability, internal consistency, and construct validity of the DS14 at three time points after myocardial infarction. The prevalence was 14.0% during hospitalization, 25.1% at 1 month, and 19.2% at 12 months. A total of 6.1% of the patients were classified as Type D personality at all three assessments, whereas 68.4% were stable non‐Type D and 25.6% changed between personality classifications. The DS14 had stable structural validity, but low temporal stability over time, especially from hospitalization to the 1‐month and 12‐month follow‐ups (κ = 0.365 and 0.397, respectively).     

The relationship between DSM-IV cluster B personality disorders and psychopathy according to Hare's criteria: clarification and resolution of previous contradictions

This study examines the relationship between DSM-cluster B personality disorders (PDs) and psychopaths according to Hare's criteria as detected by the Psychopathy Checklist (PCL:SV) in 299 violent offenders. To clarify some contradictions among several previous studies on this issue, individual cluster B PDs were looked at alone, excluding any cases of comorbidity with other PDs of this cluster. We found highly significant relationships between antisocial and borderline PD and Factor II of the PCL and a highly significant correlation between narcissistic PD and Factor I of the PCL. These results were to be expected from the theoretical basis of the development of the PCL and provide a contribution to the construct validity of the PCL, which until now has not been validated on such a large sample in Germany.     

The effect of variations of emotional expressions on mnemonic discrimination and traditional recognition memory

Face recognition occurs when a face is recognised despite changes between learning and test exposures. Yet there has been relatively little research on how variations in emotional expressions influence people’s ability to recognise these changes. We evaluated the ability to discriminate old and similar expressions of emotions (i.e. mnemonic discrimination) of the same face, as well as the discrimination ability between old and dissimilar (new) expressions of the same face, reflecting traditional discrimination. An emotional mnemonic discrimination task with morphed faces that were similar but not identical to the original face was used. Results showed greater mnemonic discrimination for learned neutral expressions that at test became slightly more fearful rather than happy. For traditional discrimination, there was greater accuracy for learned happy faces becoming fearful, rather than those changing from fearful-to-happy. These findings indicate that emotional expressions may have asymmetrical influences on mnemonic and traditional discrimination of the same face.     

Can rapport building strategies,age, and question type influence preschoolers’ disclosures of adult wrongdoing?

In the present experiment, we examined preschoolers’ disclosures of a secret as a function of rapport building strategies used in Scandinavian field settings (verbal rapport building vs. prop rapport building), age in months (33–75 months) and question type (open-ended free recall invitation vs. suggestive questions). Fifty-three preschoolers (M = 60.5 months old, SD = 11.4) witnessed a researcher break a toy and were asked to keep the toy breakage a secret. The children were thereafter interviewed about the incident. Overall, 18.9% of the children disclosed the secret after an open-ended free recall invitation. The disclosure rate rose to 83% after the final phase of the interviews when questions containing suggestive details were asked of the children. Notably, we did not observe any significant effects as a function of manipulating rapport building strategy. A linear regression model showed that child age (in months) significantly predicted the amount of reported details, with younger preschoolers reporting fewer details compared to older preschoolers. Age also predicted the amount of correct details, but not the amount of incorrect details. No age differences were found with regard to children’s disclosure tendencies or proportion of central details about the secret. Methodological limitations and practical implications will be addressed.     

Who Will Evaluate Me? Rater Selection in Multi‐Source Assessment Contexts

This study investigates the factors that motivate the preference of individuals, or ratees, participating in multi‐source assessment (MSA) processes for some raters over others. Two rater characteristics were assessed to attempt to identify these preferences: rater familiarity and the affect toward the rater. Two separate studies were conducted to assess the extent to which these characteristics are used. The extent to which the purpose of the appraisal (developmental vs. administrative) and the rating source (peer vs. subordinate) influenced the use of these characteristics was also investigated. Evidence from these two studies suggests that ratees selected their raters based on rater familiarity but not on affect. In addition, while the purpose of the appraisal did not influence selection patterns, the preference for peers was motivated by different factors than the preference for subordinates. The implications of these results for research and practice are discussed.
