The Persuasive Effects of Emotive Visual Imagery: Superficial Manipulation or the Product of Passionate Reason?

This study reevaluates the persuasive impact of emotional visual appeals within politics and examines two different explanations for their effects. One possibility is that the effects of emotive visual images are essentially superficial in nature, consistent with the view that feelings aroused by an affective image are transferred somewhat mechanically to a political candidate or cause with which it is paired. This transfer-of-affect explanation suggests that emotional appeals may work best among the least informed voters or those paying the least attention to a persuasive political message. The second possibility is that emotional appeals work via passionate reason, in which affective responses to an emotive image are integrated with, and potentially bias, reasoned thought about the accompanying message. This integrated approach leads to the counterintuitive prediction that individuals who are most highly involved in an issue (and who know the most about it) are most influenced by emotional imagery. This prediction arises from growing evidence that people highly involved in value-laden social issues generate the strongest emotional responses to issue-related persuasive appeals. These two models were tested in a study in which undergraduate students were presented with a picture of a cute or an ugly animal and a flyer from an organization advocating a pro- or anti-environment stance with respect to preserving the animal's habitat. The responses showed that emotive imagery was most persuasive among the most involved environment supporters, providing clear evidence of passionate reasoning.     

Mate choice in the domestic cat (Felis silvestris catus L.)

The domestic cat (Felis silvestris catus L.) has colonized different types of environments that differ in their spatial distribution of resources. Urban environments are characterized by highly clumped distributions of food and shelter, allowing domestic cats to live in large multimale‐multifemale groups. In such a situation, questions arise about male and female mating strategies. In particular, do females exert active mate choice? We tested this question using behavioural records on acceptance and refusal of males by estrous females. Our results showed that most females copulated with several males during a single estrus period. The variability of female behaviour was high: six females copulated with all courting males whereas three others mated with most courting males; six others copulated with half or less of the courting males. Even if some females copulated with certain males more often than with others, the identity of the most successful males changed each time. These results show that most females did not choose mates among different males available. The results are discussed in terms of optimal reproductive strategies of males and females in an urban environment. Aggr. Behav. 26:455–465, 2000. © 2000 Wiley‐Liss, Inc.

Infanticide in rural male cats (Felis catus L.) as a reproductive mating tactic

Here we report six cases of infanticide in the domestic cat directly observed in populations located in the rural environment. This is the first time that infanticide in domestic cats has been witnessed directly and described. All infanticidal males were fully adult and sexually mature unknown males. All kittens killed were within their first week of life. The killing pattern was generally the same as that described in lions. All females reacted aggressively but could not prevent the infanticide. Three hypotheses are discussed : (1) infanticide is a remnant of cat male reproductive strategy selected in the original environment; (2) the conditions of the rural environment have created a selection pressure encouraging a polymorphism of infanticidal and noninfanticidal males to evolve; (3) infanticide is an abnormal behaviour caused by environmental conditions such as human disturbance.

A Typology of Interactional Patterns Between Youth and Their Stepfathers: Associations with Family Relationship Quality and Youth Well‐Being

Stepfamilies are an increasingly common family form, many of which are headed by a resident mother and stepfather. Stepfather–child relationships exert notable influence on stepfamily stability and individual well‐being. Although various stepfather roles have been observed, more research is warranted by which stepfather–child interactions are explored holistically and across a variety of life domains (e.g., recreational, personal, academic, and disciplinary). Thus, the primary purpose of the current study is to explore varying interactional patterns between youth and their stepfathers. A latent class analysis is conducted using a representative sample of 1,183 youth (53% female; mean age = 15.64 years, SD = 1.70 years; 62% non‐Hispanic White) residing in mother–stepfather families from Wave I of the National Longitudinal Study of Adolescent to Adult Health. Latent‐class enumeration processes support a four‐class solution, with latent classes representing inactive, academically oriented, casually connected, and versatile and involved patterns of youth–stepparent interaction. Notable differences and similarities are evident across patterns with respect to family relationship quality, youth well‐being, and socio‐demographic characteristics. Differences are most stark between the inactive and versatile and involved patterns. Ultimately, the results showcase notable variation in youth–stepparent interactional patterns, and one size does not necessarily fit all stepfamilies. Family practitioners should be mindful of variation in youth–stepparent interactional patterns and assist stepfamilies in seeking out stepparent–child dynamics that are most compatible with the needs and dynamics of the larger family system.     

Factorial and convergent validity of the Youth Psychopathic Traits Inventory‐Short Version in Ghana

Studies have shown the existence of psychopathy construct in Western cultures. However, there is a general lack of research on this topical issue in non‐Western countries, specifically sub‐Saharan Africa. Consequently, this study investigated the factorial and convergent validity of the Youth Psychopathic Traits Inventory‐Short Version (YPI‐S) in 327 adolescents in Ghana. Confirmatory factor analysis supported a three‐factor structure (interpersonal, behavioural and affective) of psychopathy that was invariant across gender. These results were replicated in a cross‐validation sample comprising 363 adolescents. The YPI‐S factors correlated significantly and positively with reactive and proactive aggression, thus bolstering its construct validity. The YPI‐S and Big‐Five domains were related differently, and where significant correlations were observed, their directions generally confirmed and extended previous studies. All in all, the result generally suggested the existence of psychopathy construct among Ghanaian youth which can be described along interpersonal, affective and behavioural domains. However, the alterations made to the YPI‐S, coupled with its relatively low factor loadings and internal consistency largely, indicate cultural influences on the assessment of cross‐cultural traits. This study illuminated the problem of exporting Western‐based measures and their findings to non‐Western contexts.     

Examining the emerging entrepreneurial mindset in adolescence: A study in Nigeria

This study investigated the relationship of family environment, network, parental socio‐economic status, self‐efficacy and proactive personality on entrepreneurial intention of secondary school adolescents and the mediating role of self‐efficacy. The participants were 250 secondary school SS2 adolescents randomly selected from six secondary schools in Ibadan Metropolis, Ibadan, Oyo State, Nigeria. Structural Equation Modelling was used to analyse the data obtained from the participants. The results showed that all the contextual and individual factors had significant relationship with entrepreneurial intention and self‐efficacy partially mediated the relationship. It was suggested that counselling psychologists should consider the contextual and individual variables while assisting students in building their entrepreneurial intention.     

Personality traits of high-risk sport participants: A meta-analysis

The purpose of this meta-analysis was to examine the relationships between personality traits and participation in high-risk sport. A total of 149 effect sizes from 39 eligible articles were obtained wherein the personality traits of high-risk sport participants were compared with either low-risk sport participants or individuals not engaged in any sport. Results revealed significant effect sizes in favor of the high-risk participants for sensation seeking, extraversion, and impulsivity. Significant effect sizes in favor of the comparator groups were found for neuroticism, telic dominance, and sensitivity to punishment. No significant differences were observed in psychoticism, sensitivity to reward, socialization, agreeableness, conscientiousness, or openness. The implications of these results and potential avenues of future research are highlighted.     

Theorizing Safety Informed Settings: Supporting Staff at Youth Residential Facilities

Each year approximately 48,000 youth are incarcerated in residential placement facilities (YRFs) in the United States. The limited existing literature addressing the workforce in these settings paints a complicated picture. The YRF workforce is highly motivated to work with legal system involved youth. However, YRF staff report high rates of burnout, job fatigue, and work‐related stress. The current paper proposes solutions to persistent problems faced by staff in these settings by integrating literature from criminology, organizational psychology, trauma‐informed care, and community psychology. In doing so, we highlight previously overlooked aspects of intervention for trauma‐organized settings and respond to recent calls for community psychologists to take a more active role in the adaptation of trauma‐informed care in community settings. We conclude by advancing three recommendations, drawn from setting‐level theory and inspired by the principles of trauma‐informed care, to transform YRFs.     

Quadriceps-hamstrings intermuscular coherence during single-leg squatting 3–12 years following a youth sport-related knee injury

The purpose of this study was to determine the degree of co-contraction as per electromyographic gamma-band intermuscular coherence of the quadricep (Q) and hamstring (H) muscles during single-leg squatting (SLS), and to assess the influence of sex and self-reported knee complaints on the association between knee injury history and medial and lateral Q-H intermuscular coherence.Participants included 34 individuals who suffered a youth sport-related intra-articular knee injury 3–12 years previously, and 37 individuals with no knee injury history. Surface electromyographic signals were recorded from medial and lateral thigh muscles bilaterally to determine the gamma-band (30–60 Hz) intermuscular coherence between medial and lateral Q-H muscle pairs during SLS. Multivariable linear regression (α = 0.05) was performed to investigate the relationship between knee injury history (main exposure) and medial and lateral Q-H coherence (outcome) while accounting for the influence of sex and self-reported knee pain and symptoms (covariates).The median age of participants was 25 (range 18–30) and 67% were female. Q-H gamma-band coherence was present for 60–90% of legs. Medial and lateral Q-H coherence was higher in females compared to males. There was no evidence for an association between medial Q-H coherence, knee injury history, knee pain, or symptoms. There was evidence for an association between knee injury history and lateral Q-H coherence, which was modified by sex such that previously injured males demonstrated reduced Q-H coherence compared to uninjured males.These finding suggest that females demonstrate a more pronounced Q-H co-contraction strategy during a SLS than males regardless of knee injury history. Further, that male who suffered a youth sport-related knee injury 3–12 years previously demonstrate less Q-H co-contraction during a SLS than uninjured males. The mechanisms behind differences in neuromuscular control between males and females as well as previously injured and uninjured males require further investigation.
