Borderline and schizotypal personality disorders: mutually exclusive or overlapping?

This article is concerned with one aspect of the validity of DSM-III Axis II diagnoses, namely, the discriminability of borderline and schizotypal disorders. Forty-nine patients diagnosed by DSM-III criteria as borderline, schizotypal, or "mixed" personality disorders completed the Borderline Syndrome Index (BSI), an independent self-report 52-item instrument that has been shown to be reliable and to have discriminative validity. A one-way analysis of variance and a discriminant function analysis were conducted. Our major finding was that there were no significant differences among the groups on the BSI self-report test, although there were differences on clinical grounds. We discuss this in terms of "fuzzy set" theory and prototypic systems of classification.     

Christianity and Feminism: Do they need each other?

Abstract

This article presents personal reflections on the relationship between Christianity and feminism. It argues that Christian ideas have influenced the historical development of feminism, and that there exists a continuing affinity between some debates of the contemporary secular women's movement and those of committed Christian feminists. It presents an historical example front the nineteenth century which shows how Christian and early feminist ideas were combined in the work of Florence Nightingale. It then discusses the global empowerment of women in relation to the challenge and opportunity this poses for the Christian churches, and reflects on the wisdom of women as an important source for Christian renewal. The article argues that Christianity and feminism both challenge and need each other for mutual transformation. Without a rightly understood feminism Christianity will not remain true to its own nature and, without Christianity or rather without religion and spirituality, feminism will lack an essential source of empowerment. It also raises the question of what difference the participation of women will make to the future of Christian theology.     

Does personality vary across ability levels? A study using self and other ratings

To test the hypothesis that personality structure differs across levels of cognitive ability, personality traits of 154 participants of various ages and educational backgrounds were rated by themselves and two well-informed judges using the Estonian Personality Item Pool NEO (EPIP-NEO; Mõttus, Pullmann, & Allik, 2006). When participants were divided into two groups on the basis of their ability test scores, a relatively high cross-observer agreement was observed in the both ability groups. Although in the high-ability group personality traits were slightly less correlated and factor structures were somewhat more similar to the normative American self-report structure of the NEO-PI-R, there was no evidence that personality structure differs substantially across ability groups.     

Do parents and children know each other? A study about agreement on personality within families

The relationships between self-report and observer-rating versions of personality questionnaires within families in the Spanish cultural context were studied. In the first sample, 336 couples rated the personality of one of their children. The children also assessed their own personality. Goldberg's adjectives were administered. In the second sample, 120 university students rated the personality of their parents. Both parents also assessed their own personality. In this case, Goldberg's adjectives and the NEO-PI-R were administered. Results replicate the level of agreement found in other cultural contexts. Correlations were around .40, and the effect size of the mean differences was not large. Children were more accurate than parents, larger agreement coefficients were found for the NEO-PI-R than for Goldberg's adjectives in Sample 2, especially for the Openness factor, and no substantial role for the sex variable was found in either sample. Implications and limitations of the present study are discussed.     

Can people feel happy and sad at the same time?

The authors investigated whether people can feel happy and sad at the same time. J. A. Russell and J. M. Carroll's (1999) circumplex model holds that happiness and sadness are polar opposites and, thus, mutually exclusive. In contrast, the evaluative space model (J. T. Cacioppo & G. G. Berntson, 1994) proposes that positive and negative affect are separable and that mixed feelings of happiness and sadness can co-occur. The authors both replicated and extended past research by showing that whereas most participants surveyed in typical situations felt either happy or sad, many participants surveyed immediately after watching the film Life Is Beautiful, moving out of their dormitories, or graduating from college felt both happy and sad. Results suggest that although affective experience may typically be bipolar, the underlying processes, and occasionally the resulting experience of emotion, are better characterized as bivariate.     

Can infant self-locomotion and spatial exploration predict spatial memory at school age?

According to an embodied view of development sensorimotor activity plays a central role in cognitive development. Following this idea, we studied whether the age of achieving self-locomotion milestones and spatial exploration during the first years of life predict spatial memory at (pre)school age. Spatial memory was assessed in 51 children at ages four and six years. Parents reported retrospectively about ages of attainment of self-locomotion milestones and about the children's spatial exploration behaviour during infancy and early toddlerhood. Results show that spatial exploration positively predicts spatial memory at both ages. The age of attainment of self- locomotion does not predict spatial memory at ages four and six. These findings extend previous work that showed a relation between exploration and spatial cognition over a short period of time. Results provide preliminary support to the hypothesis, suggesting that spatial exploration predicts spatial memory also over longer periods of time.     

Social influence on physics and mathematics: local or attributive?

Summary  The article is devoted to the nature of science. To what extent are science and mathematics affected by the society in which they are developed? Philosophy of science has accepted the social influence on science, but limits it only to the context of discovery (a “locational” approach). An opposite “attributive” approach states that any part of science may be so influenced. L. Graham is sure that even the mathematical equations at the core of fundamental physical theories may display social attributes. He has used the investigations of the famous Soviet physicist V. Fock on the General Theory of Relativity which were under the influence of Marxism. The Goal of the article is to demonstrate: 1) Why Soviet science is not an appropriate subject-matter for testing the thesis of social constructivism, 2) That differnt levels of science and different stages in the development of science undergo social influences in different degrees ranging from very significant and unavoidable to absolutely trivial and easy eliminated.     

Are risk preferences consistent?: The influence of decision domain and personality

This paper examines the consistency of risk preferences across three decision domains important in most people’s lives: work, health and personal finance. We consider the degree to which the five factor model of personality and a range of factors that influence risk-related decision-making (perceived risk, framing, emotions and cost–benefit analysis) impact upon cross-domain consistency. Data were gathered from a sample of participants for whom approaches to risk were likely to vary (academics, chess players, firefighters, mountaineers and City traders). The results showed that participants could be categorised into two groups: those who were consistent in their risk preferences in three decision domains, and those who were inconsistent or domain-specific. The consistent group was significantly lower on neuroticism and higher on agreeableness and conscientiousness with a less variable approach to weighing up the costs and benefits of taking risks than the inconsistent group. The majority of the consistent group was risk averse.When the domain-specific risk preferences of the inconsistent group were examined, data showed that different combinations of personality and decision-making factors predicted risk preferences within each domain.     

Are comparative risk judgements consistent across time and events?

Research reveals pervasive optimism in people's comparative risk judgements such that people believe they are less likely than others to experience negative events. Two studies explored the extent to which people are consistent in their comparative risk judgements across time and events. Both studies found strong evidence for consistency across time and some evidence for consistency across events. The consistency across time and events was moderated by experience. Specifically, when viewed together, the studies suggest that experience produces an initial decrease in the consistency of comparative judgements (Study 2), followed by greater consistency in subsequent judgements (Study 1). The discussion focuses on reconciling evidence demonstrating consistency with evidence demonstrating variability.     

Social comparison,social attractiveness and evolution: How might they be related?

Social comparison occurs in many forms of interaction. Despite a voluminous literature, the link between human and non-human forms of social comparison has rarely been made or explored. In this paper we consider the evolution of the competency to socially compare self with others and point to its long phylogenetic history. Special regard is given to intrasexual selection, competition for parental investment, and reciprocal exchange. The evolved competency to socially compare has been important in two separate and mutually incompatible forms of social competition, based on displays of either intimidation or attractiveness. This has resulted in two self-concepts which have been called resource-holding potential (RHP) and social attention-holding power (SAHP). These primitive self-concepts derived from social competition may have been stages on the phylogenetic pathway to human self-esteem. It is suggested that an evolutionary approach adds a new dimension to current theories of social comparison.     

Inequality in personality and temporal discounting across socioeconomic status? Assessing the evidence

Personality traits such as conscientiousness and impulsivity correlate with temporal discounting, the degree to which individuals discount the value of future relative to present rewards. These variables have, in turn, been hypothesized to relate to income inequality in the United States. A key but untested assumption of this hypothesis is that the association among these variables is distinct across socioeconomic classes. The purpose of the present research is to test that assumption. N = 1100 adults with annual income ranging from at or below the poverty line ($0–$20,000) to upper-middle class ($200,000+) completed personality measures and a measure of temporal discounting. The results of our preregistered analyses indicated a positive association of income with trait planfulness, and a negative association with trait impulsivity and one parameter of temporal discounting that captures a bias to prefer sooner rewards to a greater degree if they are delivered that day. Our results can inform psychological theories of inequality and a broader conversation about effective public policy.     

Social influence and physical activity in older females: Does activity preference matter?

BackgroundOlder adults appear to have different activity preferences (prefer to be active alone or with others, or show no preference). As the activity of older females is often associated with social influences (i.e., how others influence the behavior or thoughts of another), understanding how activity preference might interact with social influences becomes important.ObjectivesThis study explored whether activity preferences would moderate the social influence – physical activity relationship in older females.MethodsThe sample for this study was 102 older females with the majority (87%) classified as ‘maintainers’. Using a cross-sectional approach, participants completed questionnaires on social influences by channel (family, friends, healthcare workers) and type (modeling, compliance, conformity, obedience), activity preferences, and physical activity.ResultsMANOVA and follow-up results revealed that friends-modeling (F (2, 99) = 8.15, p < .01) and friends-compliance/conformity (F (2, 99) = 9.82, p < .01) were greater in individuals who preferred to be active with others than those who preferred to be active alone. Results from a hierarchical multiple regression examining activity preferences as a moderator were significant (R²_change = .11). For those who preferred to be active with others, friends-modeling was positively related to activity (b = 1.28). For individuals with no activity preference, activity was positively related to friends-compliance/conformity (b = 1.38) and negatively related to friends-modeling (b = ?1.56).ConclusionResults provide preliminary evidence that activity preferences appear to moderate the relationship between the influence of friends and activity in older females, especially for those who are activity maintainers.     

Can cross-group friendships influence minority students' well-being at historically white universities?

Past research has demonstrated the negative impact of race-based rejection sensitivity (RS-race) on institutional belonging and satisfaction among minority-group students in predominantly White universities. Given research documenting the benefits of cross-group friendship for intergroup attitudes, we tested whether friendships with majority-group peers would attenuate the effects of RS-race within these contexts. In a longitudinal study of African American students (Study 1), cross-group friendships with majority-group peers buffered students high in RS-race from lack of belonging and dissatisfaction at their university. An experimental intervention (Study 2) that induced cross-group friendship replicated the findings and established their specificity for minority-group students. We discuss implications for efforts toward diversifying educational settings.     

What do epistemic logic and cognitive science have to do with each other?

Epistemic logic is a multi-faceted theory aimed at targeting notions such as knowledge, belief, information, awareness, memory and other propositional attitudes, by means of logical and semantical tools. These concepts ought to be in the spotlight of cognitive science too, but the two have not yet seriously been explored in cooperation. In this paper, it is shown that a number of possibilities is opened up by attempting to answer the question of what epistemic logic and cognitive science have to do with each other. Among the proposed answers are: (i) new quantified versions of multi-agent epistemic logic capture locutions involving object identification, giving rise to applications in representing knowledge in multi-agent systems and parallel processing. (ii) The framework of game-theoretic semantics for the ensuing logics enjoys increased cognitive plausibility as the true semantics for epistemic notions. (iii) Several recent findings in cognitive neuroscience pertaining to the notions of awareness and explicit versus implicit processing contribute to logical studies. These three connections are explored here from both logical and cognitive perspectives. Reflecting neuroscientific research, new extensions of epistemic logic are defined, increasing formal understanding of unconscious and unaware information processing in the brain, and making the formalism thus amenable to knowledge representation in multi-agent configurations.     

Metacognition and part-set cuing: Can interference be predicted at retrieval?

Although prior research has examined predictions of memory performance under conditions of interference at encoding, predictions of memory performance have not been examined for interference introduced via cues at retrieval. This was investigated in the present study by exposing participants to a random subset of to-be-recalled items just prior to retrieval (part-set cuing) and then eliciting an overall prediction of memory performance. Across three experiments, participants in part-set cuing conditions recalled proportionally fewer items than did participants who were not exposed to any cues. However, participants were unable to predict the detrimental effect of part-set cues on memory performance in either a semantic (Experiment 1) or an episodic (Experiment 2) memory task. Predictions were better calibrated after practice with part-set cuing, and there was evidence that prior experience with part-set cuing transferred to predictions made for a different part-set cuing task (Experiment 3). This suggests that only under some conditions are participants sensitive to the diminished accessibility of memories wrought by part-set cues and illustrates situations in which participants are or are not aware of variables at retrieval that influence memory performance.     

On time and ready to go: An analysis of commuters’ punctuality and energy levels at work or school

The strain of the daily commute can negatively impact performance at work. This study differentiates how various modes influence commuters’ punctuality and energy levels at work and school. The data for this study come from the 2013 McGill Commuter Survey, a university-wide survey in which students, staff and faculty described their typical commuting experience to McGill University, located in Montreal, Canada. Ten multilevel mixed-effects logistic regressions are used to determine the factors that impact (1) a commuter’s feeling of being energized when he or she arrives at work or school and (2) his or her punctuality. Our results show that weather conditions and mode of transportation have significant impacts on an individual’s energy at work and punctuality. The models indicate that drivers have the lowest odds of feeling energized and the highest odds of arriving late for work. Cyclists, meanwhile, have the highest odds of feeling energized and being punctual. Overall, this study provides evidence that satisfaction with travel mode is associated with higher odds of feeling energized and being punctual. With these findings in mind, policy makers should consider developing strategies that aim to increase the mode satisfaction of commuters. Encouraging the habit of commuting by bicycle may also lead to improved performance at work or school.     

Memory conformity: can eyewitnesses influence each other's memories for an event?

The current study investigated memory conformity effects between individuals who witness and then discuss a criminal event, employing a novel procedure whereby each member of a dyad watches a different video of the same event. Each video contained unique items that were thus seen only by one witness. Dyads in one condition were encouraged to discuss the event before each witness (individually) performed a recall test, while in a control condition dyads were not allowed to discuss the event prior to recall. A significant proportion (71%) of witnesses who had discussed the event went on to mistakenly recall items acquired during the discussion. There were no age‐related differences in susceptibility to these memory conformity effects in younger (18–30 years) as compared to older (60–80 years) participants. Possible social and cognitive mechanisms underlying the distortions of memory due to conformity are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Histrionic personality disorder and antisocial personality disorder: sex-differentiated manifestations of psychopathy?

Little is known about the etiology of histrionic personality disorder (HPD) or its relation to other personality disorders. In this study, we examined whether HPD is etiologically related to psychopathy and more specifically whether HPD and antisocial personality disorder (ASPD) are sex-typed alternative manifestations of psychopathy. In addition, based on Newman's (1987) response modulation hypothesis of psychopathy, we examined the associations between psychopathic, HPD, and ASPD features and performance on laboratory measures of passive avoidance errors and interference effects. Seventy-five live theater actors completed self-report questionnaires and two laboratory measures of response modulation, and peers completed questionnaires concerning the participants' personality disorder features. The results provided weak and inconsistent support for the hypotheses that HPD is a female-typed variant of psychopathy and that ASPD is a male-typed variant of psychopathy. Contrary to previous findings, scores on response modulation tasks were not significantly related to psychopathy, or to either HPD or ASPD. The limitations of this study and possibilities for future research in this area are outlined.     

Can,and should,behavioural neuroscience influence public policy?

Recent years have seen enormous demand amongst policy makers for new insights from the behavioural sciences, especially neuroscience. This demand is matched by an increasing willingness on behalf of behavioural scientists to translate the policy implications of their work. But can neuroscience really help shape the governance of a nation? Or does this represent growing misuse of neuroscience to attach scientific authority to policy, plus a clutch of neuroscientists trying to overstate their findings for a taste of power?     

Finishing on time: When do predictions influence completion times?

People typically predict they will finish projects earlier than they do. Whereas previous research has examined the determinants of this prediction bias, the present research explored potential consequences for behavior. In particular, we examined whether and when task completion predictions influence actual completion times. In four experiments we used anchoring manipulations to induce participants to make relatively early or late task completion predictions, and then examined when they started and/or finished the target tasks. As hypothesized, the prediction manipulation influenced completion times under certain conditions defined by the nature of the target task. Manipulated predictions affected completion times of closed tasks, defined as tasks carried out within a single, continuous session but not of open tasks, defined as tasks requiring multiple work sessions. This implies that task completion predictions help to initiate action, but their impact diminishes over the course of extensive, multi-stage projects.
