Lone‐Actor Terrorists’ Emotions and Cognition: An Evaluation Beyond Stereotypes

Lone‐actor terrorists are very often presented as emotionally and/or cognitively impaired—yet is it really the case? The present article provides the first rigorous assessment of the hypotheses according to which a high level of negative emotions, especially anger, and a lack of cognitive flexibility and complexity play a role in lone‐actor terrorists’ violent actions. Using a sample of lone‐actor terrorists’ writings, we use the LIWC (a fully automated language use analysis software) to compare terrorists’ cognition and emotion with those of other control groups, most notably nonviolent radical activists. Results strongly support the first hypothesis but clearly refute the second one, suggesting that lone‐actor terrorists are in fact characterized by a specific combination of high‐anger and high‐cognitive complexity. These method and results lay the groundwork for a more systematic and nuanced analysis of the psychology of terrorists, which is currently in a deadlock.     

The Operational Development and Empirical Testing of the Terrorist Radicalization Assessment Protocol (TRAP–18)

The Terrorist Radicalization Assessment Protocol (TRAP–18) is a structured professional judgment instrument for threat assessment of the individual terrorist. It is a rationally derived theoretical model comprising eight proximal warning behaviors and 10 distal characteristics. Empirical research on the TRAP–18 is reviewed, including both nomothetic and idiographic studies of individual terrorists in both the United States and Europe. Mean interrater reliability is 0.895 (Cohen's kappa), ranging from 0.69 to 1.0. Evidence of criterion validity has been demonstrated, including usefulness of the instrument across various extremist ideologies (jihadism, ethnic nationalism, and single-issue), and its ability to discriminate between thwarted and successful attackers. The instrument appears to advance the domain recommendations of Monahan (2012, 2016) for the risk assessment of the individual terrorist. The TRAP–18 is further discussed as a threat assessment instrument for mental health clinicians. The limitations of the current research provide direction for further studies to assess its reliability and construct, discriminant, and predictive validity.     

Suicidal Behaviors in Surviving Monozygotic and Dizygotic Co‐Twins: Is the Nature of the Co‐Twin's Cause of Death a Factor?

Genetically informative samples can address hereditary and experiential influences on suicide‐related behaviors. The frequency of suicide‐related behaviors was compared in twins from two survivor groups: (1) those whose co‐twins' deaths were suicides (monozygotic [MZ]: n = 47; dizygotic [DZ]: n = 31), and (2) those whose co‐twins' deaths were nonsuicides (MZ: n = 347; DZ: n = 170). The frequency of suicide attempts among suicide survivors was significantly higher in MZ than DZ twins, while the frequency of suicide attempts among nonsuicide twin survivors did not differ between MZ and DZ twins. Twin concordance for suicide attempts more likely reflects a genetic predisposition than a behavioral reaction to the loss.     

Cognitive Distortions of Child Molesters on Probation or Parole in Japan

The present study examined cognitive distortions of child molesters on probation or parole in Japan utilizing an 18‐item questionnaire administered in a treatment program conducted by the probation officers. This study analyzed the responses of child molesters (n = 51), non‐child‐molesting sexual offenders (n = 65), and non‐offenders (n = 64). Factor analysis of the responses showed three types of cognitive distortions: Rationalization of Offending Behavior, Minimization of Responsibility for Offending, and Minimization of Victim Harm. Welch's analysis of variance followed by Games‐Howell post hoc tests revealed that the child molesters scored significantly higher than the non‐offender group on the Rationalization of Offending Behavior subscale and the Minimization of Responsibility for Offending subscale, and significantly higher than the non‐child‐molesting sexual offender group on the Minimization of Responsibility for Offending subscale. The authors discuss the meanings of these three types of cognitive distortions and future research issues.     

Paranormal belief and the conjunction fallacy: Controlling for temporal relatedness and potential surprise differentials in component events

Recent research suggests paranormal believers are especially prone to the ‘conjunction fallacy’. The current study extends this work by presenting believers and non‐believers with eight paranormal plus eight non‐paranormal scenarios. Participants were given either a paranormal or virtually identical non‐paranormal version of each scenario. Of these, half incorporated component events which were (virtually) co‐occurring with half including components which were temporally disjointed. Analysis of Covariance (ANCOVA; controlling for gender and maths/stats/psychology qualifications) found believers made more conjunction errors than non‐believers. Neither event type (paranormal vs. non‐paranormal) nor components' temporal relationship (co‐occurring vs. disjointed) had a significant effect on conjunction biases. Believers' tendency to produce larger conjunctive estimates was unrelated to group differences in component probability estimates (surprise values) and further, could not be attributed to group differences in the perceived functional relationship between component and conjunctive events. Possible explanations are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Investigating the motivations underlying harmful social behaviors and the motivational nature of social norms

The present research applies a self‐determination theory framework to capture the broad spectrum of reasons why individuals engage in harmful normative behaviors. This correlational study (N = 242) focused on harmful behaviors that were either supported by one's in‐group or not. Participants whose in‐group encourages them to engage in a harmful behavior reported stronger motivation, both self‐determined and non‐self‐determined. Perceiving strong in‐group norms in favor of these behaviors was associated positively with the non‐self‐determined motivation pertaining to introjected regulation. The more participants agreed with an in‐group norm in favor of a harmful behavior, the stronger their self‐determination for engaging in this behavior. Results are discussed in light of self‐determination theory, normative models of social influence, and intergroup theories.     

Atmosphere in an urban nightlife setting: A case study of the relationship between the socio‐physical context and aggressive behavior

Aggression is strongly influenced by the surrounding socio‐physical context, and the development of aggressive behavior is best understood through a continuous cycle of ongoing person‐environment interactions. Empirical studies, nevertheless, have been predominantly conducted in the laboratory, studying aggression as a short‐lived phenomenon, emerging from and within an individual, and – with situational factors studied in isolation – devoid of its context. The present field study, conducted in an urban nightlife area, complements this research. A qualitative, multi‐method approach was followed by thematic analysis to investigate ongoing behavioral patterns of the crowd vis‐à‐vis the changes in the context that co‐occurred with the development of unwanted behaviors, including aggression. In our study, we identified atmosphere as a dynamic and mood‐like, but extra‐individual state of the socio‐physical setting related to the development of aggression. Our results suggest that atmosphere affects the behavior of groups and individuals by emerging from and feeding into ongoing interactions between people and the environment. At the individual level, it appears to play its part as proximate determinant of behavior; at the crowd level it reflects the synergetic product of all those persons’ states, behaviors and interactions. Implications for aggression theory and for applications aimed at curbing aggression are discussed.     

Stability analysis in K‐means clustering

This paper develops a new procedure, called stability analysis, for K‐means clustering. Instead of ignoring local optima and only considering the best solution found, this procedure takes advantage of additional information from a K‐means cluster analysis. The information from the locally optimal solutions is collected in an object by object co‐occurrence matrix. The co‐occurrence matrix is clustered and subsequently reordered by a steepest ascent quadratic assignment procedure to aid visual interpretation of the multidimensional cluster structure. Subsequently, measures are developed to determine the overall structure of a data set, the number of clusters and the multidimensional relationships between the clusters.     

Cross‐Situational Learning of Minimal Word Pairs

Cross‐situational statistical learning of words involves tracking co‐occurrences of auditory words and objects across time to infer word‐referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross‐situational statistical learning. This study examined learners’ cross‐situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON–TON), minimal pairs that differed on one vowel segment (e.g., DEET–DIT), and non‐minimal pairs that differed on two or three segments (e.g., BON–DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non‐minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word‐referent co‐occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.     

The Role of Attachment Styles and Interpersonal Problems in Suicide‐Related Behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.     

Co‐Occurring Trajectory of Mothers’ Substance Use and Psychological Control and Children's Behavior Problems: The Effects of a Family Systems Intervention

This study examined the effects of a family systems therapy (Ecologically‐Based Family Therapy [EBFT]) on the co‐occurring trajectory of mothers’ substance use and psychological control, and its association with children's problem behaviors. Participants included 183 mothers with a substance use disorder who had at least one biological child in their care. Mothers were randomly assigned to one of the three intervention conditions: EBFT—home, n = 62; EBFT—office, n = 61; or Women's Health Education, n = 60. Participants were assessed at baseline, 3, 6, 12, and 18 months post‐baseline. A dual‐trajectory class growth analysis identified three groups of mothers in regard to their change trajectories. The majority of the mothers exhibited a synchronous decrease in substance use and psychological control (n = 107). In all, 46 mothers exhibited a synchronous increase in substance use and psychological control. For the remaining 30 mothers, substance use and psychological control remained stable. Mothers in the family therapy condition were more likely to show reduced substance use and psychological control compared to mothers in the control condition. Moreover, children with mothers who showed decreased substance use and psychological control exhibited lower levels of problem behaviors compared to children with mothers showing increased substance use and psychological control. The findings provide evidence for the effectiveness of family systems therapy, EBFT, in treating mothers’ substance use, improving parenting behaviors, and subsequently improving child behavioral outcomes.     

Mapping language to the world: the role of iconicity in the sign language input

Most research on the mechanisms underlying referential mapping has assumed that learning occurs in ostensive contexts, where label and referent co‐occur, and that form and meaning are linked by arbitrary convention alone. In the present study, we focus on iconicity in language, that is, resemblance relationships between form and meaning, and on non‐ostensive contexts, where label and referent do not co‐occur. We approach the question of language learning from the perspective of the language input. Specifically, we look at child‐directed language (CDL) in British Sign Language (BSL), a language rich in iconicity due to the affordances of the visual modality. We ask whether child‐directed signing exploits iconicity in the language by highlighting the similarity mapping between form and referent. We find that CDL modifications occur more often with iconic signs than with non‐iconic signs. Crucially, for iconic signs, modifications are more frequent in non‐ostensive contexts than in ostensive contexts. Furthermore, we find that pointing dominates in ostensive contexts, and suggest that caregivers adjust the semiotic resources recruited in CDL to context. These findings offer first evidence for a role of iconicity in the language input and suggest that iconicity may be involved in referential mapping and language learning, particularly in non‐ostensive contexts.     

Early Postpartum Parental Preoccupation and Positive Parenting Thoughts: Relationship with Parent–Infant Interaction

Parenting behaviors and parent–infant emotional bonding during the early postpartum months play a critical role in infant development. However, the nature and progression of parental thoughts and their relationship with interactive behaviors have received less research. The current study investigated the trajectory of parental thoughts and behaviors among primiparous mothers (n = 18) and fathers (n = 15) and multiparous mothers (n = 13) and fathers (n = 13), which were measured at the first and third postpartum month. At the third postpartum month, the relationship between parental thoughts and parental interactive behaviors also was tested. Mothers and fathers showed high levels of preoccupations and caregiving thoughts during the first postpartum month that significantly declined by the third postpartum month. In contrast, positive thoughts about parenting and the infant increased over the same time interval. Mothers presented higher levels of preoccupations and positive thoughts than did fathers, and first‐time parents reported more intense preoccupations than did experienced parents. Although maternal sensitivity was inversely related to maternal anxious thoughts, paternal sensitivity was predicted by higher levels of anxious as well as caregiving and positive thoughts.     

Perfectionistic Concerns,Social Negativity,and Subjective Well‐Being: A Test of the Social Disconnection Model

Partner‐specific perfectionistic concerns (PC) include concern over mistakes, self‐criticism, and socially prescribed perfectionism as it pertains to one's partner. The social disconnection model proposes that PC influences well‐being indirectly through interpersonal problems. Thus, we hypothesized that social negativity (expressed anger, hostility, and rejection) would mediate the relationship between dyadic PC and subjective well‐being. Data from 203 romantic dyads (92.1% heterosexual) were collected using self‐report surveys and a four‐wave, 4‐week longitudinal design. Participants were predominantly female (53.1%), young (M = 22.69 years), and Caucasian (82.3%). Data were analyzed using an actor‐partner interdependence model with multilevel structural equation modeling. There were significant actor effects at the between‐subjects and within‐subjects levels, and significant partner effects for the relationship between PC and social negativity at the within‐subject level. Social negativity mediated the relationships between PC and both negative affect and life satisfaction. However, positive affect was more weakly related to PC and social negativity. The social disconnection model was supported. PC was positively associated with one's own social negativity and evoked hostile behaviors from one's partner. Hostile, rejecting behaviors reduced the well‐being of the actor, but not the partner. Results suggest perfectionism may be best understood within an interpersonal context.     

Readiness to adaptively change under three conditions: Clinical,careers, and natural change situations

The Adaptive Change Model (ACM) was developed as an alternative form of the Transtheoretical Model of Change to address some of the criticisms of early operationalisation. Both models provide a framework for measuring the potentialities of change and to facilitate targeted behaviour change in general and clinical settings. In this research, the eight factors of the Adaptive Change Questionnaire (ACQ) operationalising the ACM were validated using confirmatory factor analysis, involving 238 respondents. The findings indicated a good fit between the model and data. A comparison of the mean scores of the factors of the ACM showed respondents seeking clinical therapy (n = 85) were lower on self‐rating of factors related to adaptive change than a group receiving career counselling (n = 88) and a non‐therapy group (n = 65). The ACQ factors correctly predicted the allocation of 79.3% of the clinical and non‐therapy respondents which confirmed previous research. The relevance of the findings for therapeutic interventions and future research are discussed.     

Parents Produce Explicit Cues That Help Toddlers Distinguish Joking and Pretending

While separate pieces of research found parents offer toddlers cues to express that they are (1) joking and (2) pretending, and that toddlers and preschoolers understand intentions to (1) joke and (2) pretend, it is not yet clear whether parents and toddlers consider joking and pretending to be distinct concepts. This is important as distinguishing these two forms of non‐literal acts could open a gateway to understanding the complexities of the non‐literal world, as well as the complexities of intentions in general. Two studies found parents offer explicit cues to help 16‐ to 24‐month‐olds distinguish pretending and joking. Across an action play study (n = 25) and a verbal play study (n = 40) parents showed more disbelief and less belief through their actions and language when joking versus pretending. Similarly, toddlers showed less belief through their actions, and older toddlers showed less belief through their language. Toddlers' disbelief could be accounted for by their response to parents' language and actions. Thus, these studies reveal a mechanism by which toddlers learn to distinguish joking and pretending. Parents offer explicit cues to distinguish these intentions, and toddlers use these cues to guide their own behaviors, which in turn allows toddlers to distinguish these intentional contexts.     

Commitment through Employee Volunteering: Accounting for the Motives of Inter‐Organisational Volunteers

This study investigated whether participating in inter‐organisational (i.e. self‐directed, non‐strategic) employee volunteering, which is common but rarely studied, is associated with increased organisational commitment. We find evidence for this relation in a sample (N = 385) of employee volunteers and their non‐volunteering co‐workers. We statistically account for self‐selection into the volunteering program by incorporating individual motives for volunteering. Volunteers compared to non‐volunteers exhibited relatively stronger motives of expressing altruistic values and avoiding negative affect, but a weaker motive of attaining career advancement. Our findings point to an efficient way of increasing organisational commitment that is relatively inexpensive to implement. They also complement existing research from other employee volunteering contexts, pointing to a possible trade‐off between the desired outcomes of effectively managing volunteering programs.     

Perspective‐Taking as a Strategy for Improving Intergroup Relations: Evidence,Mechanisms, and Qualifications

In this article, we review empirical research investigating the efficacy of perspective‐taking – the active consideration of others' mental states and subjective experiences – as a strategy for navigating intergroup environments. We begin by describing some of the benefits accrued from perspective‐taking: more favorable implicit and explicit intergroup evaluations, stronger approach‐oriented action tendencies and positive non‐verbal behaviors, increased intergroup helping, reduced reliance on stereotype‐maintaining mental processes, and heightened recognition of intergroup disparities. We then discuss several of the processes through which perspective‐taking operates, focusing specifically on two affective (i.e., parallel and reactive empathy) and two cognitive (i.e., shifts in attributional thinking and self‐outgroup merging) mechanisms. We also note several moderating factors based on perceiver characteristics, target characteristics, and features of the surrounding context that qualify the effects of perspective‐taking. Finally, we conclude by suggesting potential directions for future research on intergroup perspective‐taking.     

Children's memory for television advertising: effects of programme–advertisement congruency

The effects of the surrounding programme environment and level of involvement upon children's memory (year 6 primary school, mean age 11.1, SD = 0.4, 48 boys and 69 girls) for television advertisements was examined by manipulating the degree of congruency between the production genre of the programme and the advertisements embedded within it. In Experiment One (n = 56) the ad‐break comprised either all cartoons (n = 4) or all non‐cartoons (n = 4). In Experiment Two (n = 61) cartoon and non‐cartoon advertisements were equally represented in each ad‐break. After viewing, participants provided evaluative ratings of the programme and completed memory tests for advertisements, using prompted recall and brand‐recognition tasks. Memory performance overall was better for cartoon advertisements than for non‐cartoon advertisements, with the latter being poorly remembered when presented in the non‐cartoon programme. In Experiment Two, the programme had no effect on overall recall of advertising, but was related to brand recognition, which was better for advertisements placed in the cartoon programme. Free recall of non‐cartoon advertisements was best when placed in the cartoon programme, while free recall only of cartoon advertisements was best when placed in the non‐cartoon programme. The measures of audience involvement (programme ratings) did not show any significant correlation with memory for advertising. Copyright © 2002 John Wiley & Sons, Ltd.     

Cognitive correlates of mathematical achievement in children with cerebral palsy and typically developing children

Background . Remarkably few studies have investigated the nature and origin of learning difficulties in children with cerebral palsy (CP). Aims . To investigate math achievement in terms of word‐problem solving ability in children with CP and controls. Because of the potential importance of reading for word‐problem solving, we investigated reading as well. Sample . Children with CP attending either special (n= 41) or mainstream schools (n= 16) and a control group of typically developing children in mainstream schools (n= 16). Method . Group differences in third grade math and reading, controlled for IQ, were tested with analyses of co‐variance (ANCOVAs). Hierarchical regression was used to investigate cognitive correlates of third grade math and reading. Predictors included verbal and non‐verbal IQ measured in first grade, components of working memory (WM) and executive function (EF) measured in second grade, and arithmetic fact fluency and reading measured in third grade. Results . Children with CP in special schools performed significantly worse than their peers on word‐problem solving and reading. There was a trend towards worse performance in children with CP in mainstream schools compared to typically developing children. Conclusions . Impairments of non‐verbal IQ and WM updating predicted future difficulties in both word‐problem solving and reading. Impairments of visuospatial sketchpad and inhibition predicted future word‐problem, but not reading difficulty. Conversely, deficits of phonological loop predicted reading but not word‐problem difficulty. Concurrent arithmetic fact fluency and reading ability were both important for word‐problem solving ability. These results could potentially help to predict which children are likely to develop specific learning difficulties, facilitating early intervention.
