Of mice and marbles: Novel perspectives on burying behavior as a screening test for psychiatric illness

Burying forms part of the normal behavioral routine of rodents, although its expression is species-specific. However, it has been suggested that aberrant burying behavior, of which marble-burying (MB) is an example, may represent neophobic and/or compulsive-like behavior. In the present investigation, we assessed MB in an established animal model of obsessive–compulsive disorder (OCD)—namely, spontaneous stereotypy in the deer mouse—to establish whether high (H) stereotypy is associated with neophobia and/or another compulsive endophenotype, i.e. MB, as compared to nonstereotypical (N) controls. A three-trial, one-zone MB test was performed over three consecutive evenings both before and after chronic treatment with high-dose (50 mg/kg/day) oral escitalopram. Neophobia was measured via the number of marbles buried during the first pre- and posttreatment MB trials, and compulsive-like behavior via the number of marbles buried over all pre- and posttreatment MB trials. The data from the present study support earlier findings that burying is a normal behavioral routine (inherent burying behavior, IBB) that is expressed by all deer mice, irrespective of stereotypical cohort, and is not associated with either neophobia or compulsiveness. Indeed, chronic escitalopram treatment, which is similarly effective in treating clinical anxiety and OCD, as well as in attenuating H behavior, failed to influence IBB. Although 11 % of the animals presented with a unique burying endophenotype (high burying behavior), escitalopram also failed to attenuate said behavior, necessitating further investigation as to its relevance. In conclusion, MB cannot be regarded as a measure of anxiety-like or compulsive behavior in the deer mouse model of OCD.     

Changing views of emotion regulation and neurobiological models of the mechanism of action of psychotherapy

Influential neurobiological models of the mechanism of action of psychotherapy attribute its success to increases of activity in prefrontal areas and decreases in limbic areas, interpreted as the successful and adaptive recruitment of controlled processes to achieve emotion regulation. In this article, we review the behavioral and neuroscientific evidence in support of this model and its applicability to explain the mechanism of action of psychotherapy. Neuroimaging studies of explicit emotion regulation, evidence on the neurobiological substrates of implicit emotion regulation, and meta-analyses of neuroimaging studies of the effect of psychotherapy consistently suggest that areas implicated in coding semantic representations play an important role in emotion regulation not covered by existing models based on controlled processes. We discuss the findings that implicate these same areas in supporting working memory, in encoding preferences and the prospective outcome of actions taken in rewarding or aversive contingencies, and show how these functions may be integrated into process models of emotion regulation that depend on elaborate semantic representations for their effectiveness. These alternative models also appear to be more consistent with internal accounts in the psychotherapeutic literature of how psychotherapy works.     

Why are familiar-only experiences more frequent for voices than for faces?

Hanley,Smith, and Hadfield (1998) showed that when participants were asked to recognize famous people from hearing their voice , there was a relatively large number of trials in which the celebrity's voice was felt to be familiar but biographical information about the person could not be retrieved. When a face was found familiar, however, the celebrity's occupation was significantly more likely to be recalled. This finding is consistent with the view that it is much more difficult to associate biographical information with voices than with faces. Nevertheless, recognition level was much lower for voices than for faces in Hanleyet al.'s study,and participants made significantly more false alarms in the voice condition. In the present study, recognition performance in the face condition was brought down to the same level as recognition in the voice condition by presenting the faces out of focus. Under these circumstances, it proved just as difficult to recall the occupations of faces found familiar as it was to recall the occupations of voices found familiar. In other words, there was an equally large number of familiar-only responses when faces were presented out of focus as in the voice condition. It is argued that these results provide no support for the view that it is relatively difficult to associate biographical information with a person's voice. It is suggested instead that associative connections between processing units at different levels in the voice-processing system are much weaker than is the case with the corresponding units in the face-processing system. This will reduce the recall of occupations from voices even when the voice has been found familiar. A simulation was performed using the latest version of the IAC model of person recognition (Burton, Bruce, & Hancock, 1999) which demonstrated that the model can readily accommodate the pattern of results obtained in this study.     

Are absolute frequencies,relative frequencies,or both effective in reducing cognitive biases?

Biases in probabilistic reasoning are affected by alterations in the presentation of judgment tasks. In our experiments, students made likelihood judgments that an event was produced by various causes. These judgments were made in terms of probability, relative frequency or absolute frequency on a full or a pruned list of causes. When they had little personal experience of the event (causes of death), the pruning bias was smaller with relative frequencies than with absolute frequencies or probabilities. When they had more personal experience of the event (missing a lecture), the bias was less with both types of frequency than with probability but still lowest with relative frequency. We suggest that likelihood information is usually stored as relative frequencies when it has been obtained from public sources but that it is based on event counts when it is derived from personal experience.

Receptivity to dating and marriage across the religious divide in Northern Ireland: The role of intergroup contact

Intergroup contact has long been recognized as an important factor in promoting positive intergroup attitudes. However, in operationalizing intergroup attitudes, previous studies have rarely investigated attitudes toward one of the most intimate forms of contact, romantic relationships. In this study (N = 176), we expand the intergroup contact literature to examine the association between intergroup contact and, arguably, a litmus test of intergroup attitudes: receptivity to intergroup romance. We do so in Northern Ireland, a context that is historically and presently characterized by sectarian division and tension between Catholics and Protestants. Our findings reveal that intergroup contact is positively associated with receptivity to both dating and marrying an outgroup member. These associations are mediated by ingroup norms toward outgroup romances. General outgroup attitudes were also found to be positively associated with contact but, in contrast to romantic attitudes, this association was shown, for the first time, to be simultaneously mediated by ingroup norms, anxiety, empathy, and trust. In addition, strength of ingroup identification played a moderating role, with a stronger positive relationship between contact and both romantic and general outgroup attitudes among higher identifiers. The findings highlight the importance of examining attitudes toward intergroup romantic relationships, as well as understanding the different mediating and moderating mechanisms which may account for how contact influences general attitudes and romantic attitudes. In the wake of the UK vote to leave the European Union, they also serve as an important reminder of how intergroup contact can be effective in promoting peace in Northern Ireland.     

Conceptualizing Creativity: General and Cultural Biases in Gough's Creative Personality Scale

This study analyzes the validity of Gough's Creative Personality Scale (CPS) for the Adjective Check List (ACL) by using 1773 Swiss, South Korean, and Mainland Chinese students as a sample. Four sources of potential bias were identified in Gough's CPS, two of which are general and two cultural in nature. The two general biases were investigated by conducting correlation analyses and evaluating alternative scoring methods for the CPS. As a result of the first bias, checking a large number of adjectives was found to be more important for achieving a high score than checking the relevant ones. Due to the second bias, the CPS score mostly depends on the number of positive adjectives checked while negative items have little impact. The two cultural biases were analyzed using an implicit version of the CPS (iCPS) and factor analysis. The latter revealed three different clusters of creativity type: exploratory‐type, socially responsible‐type, and intellectual‐type creativity. Based on cultural background, they are all weighted differently, causing a potential experiential bias in the CPS. Findings indicate that in South Korea and Mainland China socially responsible‐type creativity dominates whereas in Switzerland exploratory‐type creativity prevails. Findings from the iCPS suggest the second cultural bias, the socially desirable responding bias arising from differences in responding styles among the three cultures.
