Predictors of aggression in Southeast Asian female prisoners

Although aggression is universal, few studies examine violence from an Asian perspective, and even fewer consider female offenders from Southeast Asia. The current study examined whether correlates of aggression in western male offenders are similarly effective for predicting aggression in female inmates (n = 114) from a local prison in Singapore. Aggression was measured using the Buss–Perry Aggression Questionnaire (comprising dimensions of physical and verbal aggression, anger and hostility) which we sought to predict from measures of impulsivity, general personality traits (neuroticism, agreeableness), psychopathy, and empathy. Impulsivity and agreeableness were significant predictors of self-reported physical and verbal aggression and anger, whereas neuroticism contributed to anger. Neuroticism and psychopathy were significant predictors of hostility. Empathy did not significantly predict any of the four aggression dimensions. Personality, impulsivity and psychopathy appear fair predictors of aggression for female offenders from Southeast Asia, just as they are for the western male offenders.     

Facial asymmetry detection in patients with body dysmorphic disorder

Cognitive-behavioral models of body dysmorphic disorder (BDD) propose that individuals with BDD may possess a better or more developed sense of aestheticality than do individuals without BDD. Evidence for this proposition, however, is limited. One perceptual process that could contribute to heightened aestheticality is the ability to detect differences in symmetry. In this experiment we tested whether individuals with BDD (n = 20), relative to individuals with obsessive compulsive disorder (OCD; n = 20) and healthy controls (n = 20), show an enhanced ability to detect differences in the symmetry of others’ faces, symmetry of dot arrays, and/or show a greater preference for symmetrical faces. Individuals with BDD were not significantly more accurate in detecting differences in facial symmetry or dot arrays relative to individuals with OCD and healthy controls. Individuals with OCD took longer to make facial symmetry judgments than did individuals in the other two groups. All participants, regardless of diagnostic group, preferred more symmetrical faces than nonsymmetrical ones. Taken together, our results do not support a heightened perceptual ability or evaluative preference for symmetry among individuals with BDD.     

Survey and behavioral measurements of interpersonal trust

Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior.     

Establishing construct validity for Openness-to-Experience in middle childhood: Contributions from personality and temperament

Controversy exists over the validity of child Openness-to-Experience (OE). To establish construct validity for child OE, data were collected for 346 children (51% girls) aged 9-to-10-years (M = 9.92, SD = 0.83). Parents completed questionnaires about their children’s personality, temperament, and behavioral problems and competencies. Factor analyses of relevant personality and temperament facets revealed a robust OE factor made up of three facets: Intellect, Imagination, and Sensitivity. Evidence for convergent and discriminant validity was established via associations with other personality traits, and behavioral problems and competencies. Results underscore the importance of drawing from both temperament and personality literatures in attempts to establish construct validity for child trait domains as well as examining facet-level associations between OE and child behavior.     

Associations between personality traits, physical activity level, and muscle strength

Associations among personality as measured by the Five Factor Model, physical activity, and muscle strength were assessed using data from the Baltimore Longitudinal Study of Aging (N = 1220, age: mean = 58, SD = 16). General linear modeling with adjustment for age, sex, race, and body mass index, and bootstrapping for mediation were used. We found neuroticism and most of its facets to negatively correlate with strength. The extraversion domain and its facets of warmth, activity, and positive-emotions were positively correlated with strength, independent of covariates. Mediation analysis results suggest that these associations are partly explained by physical activity level. Findings extend the evidence of an association between personality and physical function to its strength component and indicate health behavior as an important pathway.     

How does non-nutritive sucking support infant feeding?

Fifty nine premature infants participated in a randomized controlled study to determine the effectiveness of non-nutritive sucking (NNS). It was predicted that NNS would not accelerate the development of full oral feeding or early language skills as sometimes perceived in practice. However, it was predicted that using NNS as a strategy to support parents to identify and respond to early communication and oral readiness signs would increase confidence in infant management and enable quicker discharge home. Infants were aged 26–35 weeks gestation. Infants with no significant difficulties were randomly assigned to one of three groups; Group 1, NNS pre-tube feeding (n = 19); Group 2, NNS on onset of tube feeding (n = 20) and Group 3, Control (n = 20). Follow-up occurred at 6 months. There were no significant differences with number of days to full oral feeding between the groups receiving NNS and the Control group, χ²(2, n = 59) = 4.33, p = .115. A significant difference in number of days in hospital between the Control group and the other two groups was found χ² (2, n = 59) = 7.678, p = .022. Significant changes were noted with the development of more normal sucking patterns in Groups 1–3. At 6 months there were no significant differences in receptive or expressive language skills between all groups. NNS had no significant impact on the transition to full oral feeding or later language development. There was a significant difference in the number of days in hospital between the Control group and the other two groups which involved parents in identification of early communication signs. Possible reasons for this change and future directions are discussed.     

Carver and Whites’ BIS/FFFS/BAS scales and domains and facets of the Five Factor Model of personality

Few empirical studies have investigated the relationship between Gray’s Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) of personality. In a large sample of undergraduates (N = 779), we examined the relationship between FFM domains and facets and the revised RST (see Gray & McNaughton, 2000). Regression and partial correlation analyses indicated that only FFM Agreeableness discriminates between the BIS and FFFS. Other differences at the facet level were found for Neuroticism facets of Self-Consciousness and Angry Hostility (negatively), Agreeableness facets of Compliance and Modesty, and Conscientiousness facets of Self-Discipline and Deliberation. These findings emphasize social inhibition and constraint in the BIS, compared to the FFFS.     

Individual differences and propensity to engage with in-vehicle distractions - A self-report survey

Ratings of severity and frequency of engagement with distracting driver behaviours are reported in this paper. Survey data were collected using an anonymous online questionnaire. Four hundred eighty-two respondents contributed to the survey during a 2 month data collection period. Results indicate that the three behaviours rated as most distracting when driving were (i) writing text messages (41%), (ii) reading text messages (62%), and (iii) using a cellular telephone hand-held (52%). The three most frequently reported distracting behaviours that resulted in accidents were (i) ‘interaction with child passengers’ 2.1% (near misses = 7.5%), (ii) both, route guidance destination entry with 2% (near misses = 2.8%) and use of an ‘… add-on media device, e.g., an iPod’ with 2% (near misses = 3.9%), and (iii) the three items ‘reading a text message’, ‘following advice from a route guidance system’, and ‘interaction with pets’, all with 1.7% of respondents reporting an accident when undertaking the activity (with 6.5%, 3%, and 2.2% respectively for near misses). Two hierarchical regression models were explored. The first introducing personal factors, i.e., age, extraversion, agreeableness, conscientiousness, emotional stability and intellect (R² = 0.131, p < 0.001). The second controlled for variables in the first model and introduced driver-related variables, mileage, penalty points, and frequency of accidents with assumed responsibility (R² = 0.253, p < 0.001). This model identified age, extraversion, mileage, penalty points and accidents all to be significant predictors of engagement with unnecessary distractions. The data presents a picture of widespread awareness of, and engagement with, distracting behaviours by drivers in the United Kingdom. Findings from the hierarchical regressions suggest scope may exist to mediate the levels of distracting behaviours by exploring individual differences and driving styles.     

Deontic and epistemic reasoning in children

It is widely accepted that adults show an advantage for deontic over epistemic reasoning. Two published studies (Cummins, 1996b; Harris and Núñez, 1996, Experiment 4) found evidence of this “deontic advantage” in preschool-aged children and are frequently cited as evidence that preschoolers show the same deontic advantage as adults. However, neither study has been replicated, and it is not clear from either study that preschoolers were showing the deontic advantage under the same conditions as adults. The current research investigated these issues. Experiment 1 attempted to replicate both Cummins’s and Harris and Núñez’s studies with 3- and 4-year-olds (N = 56), replicating the former with 4-year-olds and the latter with both 3- and 4-year-olds. Experiment 2 modified Cummins’s task to remove the contextual differences between conditions, making it more similar to adult tasks, finding that 4-year-olds (n = 16) show no evidence of the deontic advantage when no authority figure is present in the deontic condition, whereas both 7-year-olds (n = 16) and adults (n = 28) do. Experiment 3 removed the authority figure from the deontic condition in Harris and Núñez’s task, again finding that 3- and 4-year-olds (N = 28) show no evidence of the deontic advantage under these conditions. These results suggest that for preschoolers, the deontic advantage is reliant on particular contextual cues such as the presence of an authority figure, in the deontic condition. By 7 years of age, however, children are reasoning like adults and show evidence of the advantage when no such contextual cues are present.     

The P-psychopathy continuum: Facets of Psychoticism and their associations with psychopathic tendencies

Eysenck proposed that psychopathy is at the extreme end of the Psychoticism (P) personality dimension (Eysenck & Eysenck, 1976). This study examined (i) whether psychopathy-relevant P items of the EPQ-R can form psychometrically valid facets that map onto the conceptualization of the two-, three- or four-factor models of psychopathy using confirmatory factor analysis (N = 577) in a normal population; and (ii) whether those P-facets have criteria-related validity in associations with self-reported primary and secondary psychopathy, impulsivity (subsample N = 306), and measures of trait empathy and aggression (subsample N = 212). The four-factor model incorporating affective, interpersonal, impulsive, and antisocial facets of P was superior to the two-factor model; however, the three-factor conceptualization excluding the antisocial P-facet was the best fit. The facets show predicted divergent associations with primary and secondary self-reported psychopathy and trait measures. Findings are discussed in light of Eysenck’s P-psychopathy continuity hypothesis and the applicability of facet approaches to the prediction of psychopathic and antisocial tendencies.     

Big-five personality and BIS/BAS traits as predictors of career exploration: The mediation role of career adaptability

Based on career construction theory, the current research examined whether career adaptability mediates the relations of the personality traits (Five-Factor Model personality traits and behavioral inhibition and activation systems (BIS/BAS)) to career exploration behavior. Results from a survey in Chinese university students (N = 264) showed that career exploration correlated negatively with neuroticism, and positively with openness to experience, extroversion, agreeableness, conscientiousness and BAS. Results of regression analyses further showed that openness to experience, agreeableness, conscientiousness and BAS served as the strongest predictors for career exploration. In addition, career adaptability was shown to be a key mediator for the relationships between personality traits and career exploration behavior. Career concern and career curiosity were the more important dimensions in the mediation model. These findings advance current understandings on how different personality traits predict career exploration behavior.     

Portuguese adaptation of the Gudjonsson Suggestibility Scales (GSS1 and GSS2): Empirical findings

In study 1 (n = 51, M_age = 21.4 years, SD = 5.7), the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scales ( Pires, 2011) was shown through the comparison of means of the original ( Gudjonsson, 1997) and the translated scales and the analysis of the correlations between the GSS1 and GSS2 scores. The relationships between interrogative suggestibility and the big five were also addressed and the results point to independence between suggestibility and personality, which is in line with Polczyk’s findings (2005). Study 2 (n = 87, M_age = 48.9 years, SD = 20.7) explored the relationships among interrogative suggestibility, the state–trait anxiety and demographic variables (i.e., age and gender). There were no significant relationships between anxiety and suggestibility. These results are in line with other studies that point to a lack of relationship between suggestibility and anxiety in normal samples (  and ). As for the relationships between age and interrogative suggestibility, ANCOVA confirmed that the increased suggestibility in old age was not due to age differences but rather to the limited memory capacity of the older adults group. There were no significant gender differences in the GSS1 subscales.     

Predicting counterproductive work behaviors with sub-clinical psychopathy: Beyond the Five Factor Model of personality

Organizational psychologists examining personality’s relation to work behavior have focused largely on the “normal” traits comprising the Five Factor Model (FFM). However, given the aversive nature of sub-clinical psychopathy (e.g., callous affect, impulsivity), we posit that this toxic personality profile will enhance the prediction of negative work outcomes, namely forms of counterproductive workplace behavior (CWB). Study 1 (N = 193) examined the value of sub-clinical psychopathy and the FFM in predicting intentions to engage in CWB; results support prior research indicating that both agreeableness and conscientiousness significantly correlated with CWB. In addition, sub-clinical psychopathy predicted CWB above and beyond the FFM. Study 2 (N = 360) extended the findings of Study 1 by examining interpersonally deviant behavior in a team context. While agreeableness was significantly related to interpersonal deviance in Study 2, conscientiousness was not. Results from Study 2 replicate Study 1, suggesting that sub-clinical psychopathy accounted for the majority of the explained variance in interpersonal deviance. Overall, the results support the value of using sub-clinical psychopathy to predict CWB.     

The Five Factor Model in personnel selection: Measurement equivalence between applicant and non-applicant groups

This study investigates the measurement equivalence of a Five Factor measure of personality between applicant and non-applicant samples. The Big Five Questionnaire-2 was administered in two samples: A group of volunteers (n = 903), who completed the test for research purposes, and a group applying for jobs, who completed the test during hiring procedures (n = 401). Multiple-group confirmatory factor analysis on item composites was conducted to test for the equivalence of factor covariance and mean structures of twenty facets of the Five Factors. Item-level analyses were carried out through analysis of variance to further examine the issue of measurement invariance. Findings suggested that personality facets have the same measurement unit across applicants and non-applicants, while a lack of equivalence was found in the origin of the scales. Similar results were found at the item-level. Implications for personality assessment are advanced and discussed.     

Prediction of toddlers’ expressive language from maternal sensitivity and toddlers’ anger expressions: A developmental perspective

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.     

Gender differences in rumination: A meta-analysis

Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.     

An empirical examination of sex differences in scoring preschool children's aggression

Sex differences in adults’ observations and ratings of children’s aggression was studied in a sample of preschool children (N = 89, mean age = 44.00 months, SD = 8.48). When examining the direct observations made by trained observers, male observers, relative to female observers, more frequently recorded aggressive bouts, especially of boys. On rating scales assessing aggression, trained male raters also gave higher aggressive ratings than female raters. Lastly, we compared the ratings of trained female raters and female teachers on the same scale and found no differences. Results are discussed in terms male raters’ and observers’ prior experiences in activating their experiential schemata where males’ greater experience in aggression, relative to that of females, leads them to perceive greater levels of aggression.     

How well can the theory of planned behavior account for occupational intentions?

We tested the capacity of an extended version of the theory of planned behavior (TPB) to account for intentions to work for the UK’s National Health Service (NHS) as a nurse, physiotherapist or radiographer amongst three groups: professionally unqualified (N = 507), in professional training (N = 244), and professionally qualified (N = 227). We found strong support for the three core TPB variables attitude, subjective norm and perceived behavioral control as predictors of behavioral intention, and limited support for two additional variables: moral obligation and identification. There were some differences in the relative importance of TPB variables between groups. We conclude that the TPB has utility for more complex behaviors as well as simpler ones that are more frequently researched. However, more attention should be paid to differences in people’s circumstances, particularly regarding past vocational decisions and behavior, and to obstacles to implementing an intention.     

The prevalence of compulsive hoarding and its association with compulsive buying in a German population-based sample

The aims of the study were to estimate the prevalence rate of compulsive hoarding, and to determine the association between compulsive hoarding and compulsive buying in a nationally representative sample of the German population (N = 2307). Compulsive hoarding was assessed with the German version of the Saving Inventory-Revised (SI-R; Frost, R.O., Steketee, G., & Grisham, J. (2004). Measurement of compulsive hoarding: saving inventory-revised. Behaviour Research and Therapy, 42, 1163-1182.). The point prevalence of compulsive hoarding was estimated to be 4.6%. Individuals with compulsive hoarding did not differ significantly from those without compulsive hoarding regarding age, gender, and other sociodemographic characteristics. Significant correlations were found between the compulsive hoarding and the compulsive buying measures. Participants with compulsive hoarding reported a higher propensity to compulsive buying than respondents without hoarding. About two thirds of participants classified as having compulsive hoarding were also defined as suffering from compulsive buying. In summary, these results suggest that compulsive hoarding may be relatively prevalent in Germany and they confirm the close association between compulsive hoarding and compulsive buying through the investigation of a large scale representative sample.     

Did she mean to do it? Acquiring a folk theory of intentionality

The ability to both identify and explain others’ intentional acts is fundamental for successful social interaction. In two cross-sectional studies, we investigated 3- to 9-year-olds’ (n = 148) understanding of the folk concept of intentionality, using three types of intentionality measures. The relationship between this type of reasoning and false belief and interpretive mind understanding was also examined. Judgment of the appropriateness of an explanation was based on adult responses (n = 20). Overall, the results indicated that the ability to both identify and appropriately explain a range of intentional acts does not fully emerge until 7 years of age or later. The pattern of explanations revealed the gradual development of a folk concept of intentionality. Preschool- and early school-age children focused on the protagonists’ desires and actions, whereas 8- and 9-year-olds and adults were more likely to reference the protagonists’ awareness and skills.
