Still Dazed and Confused: Midlife Marijuana Use by the Baby Boom Generation

National drug use surveys show the baby boom generation using marijuana in record numbers. We test hypotheses based on social learning, rational choice, and strain theories to explain marijuana use among adults aged 50–64 with an intersectional lens to consider racial and gender group differences. Social learning perspectives, pointing to pro-marijuana attitudes and norms acquired through culture, and rational choice approaches, in which marijuana use is perceived as a low-risk activity, are both strongly supported. Strain generated by mental and physical health problems emerges as a relevant factor for marijuana use among specific racial and gender minority groups of older adults.     

Perceived Powerlessness as a Mediator between Life Stressors and Deviant Behaviors

ABSTRACT

The Threat Appraisal and Coping Theory suggest that when facing life stressors, individuals may perceive that they are powerless to change them, which may prompt “maladaptive coping” deviant behaviors. The present study examined the relationship between 5 types of deviant behavior and perceived powerlessness, and whether powerlessness served as a mediator between life stressors and deviance. Money stress and powerlessness increased risk for watching porn, cross-dressing, hoarding, and medication misuse. Work stress and powerlessness significantly increased risk for watching porn, cross-dressing, and medication misuse. Family stress and powerlessness increased risk for watching porn, cross-dressing, disordered eating, hoarding, and medication misuse.     

Socialization of maths in the home environment: using voice recordings to study maths talk / Socialización de matemáticas en el hogar: uso de grabaciones de voz para estudiar conversaciones matemáticas

Abstract

This study examined conversations about maths (maths talk) between mothers and their preschoolers in the home setting. Naturalistic conversational data on 40 mother-child dyads from a Midwestern area in the United States were gathered using the Language ENvironment Analysis System (LENA). A sample of up to four hours of talk during shared meals for each dyad was transcribed, coded and analysed in terms of maths talk. The results showed that all mothers and children engaged in maths talk during the hours recorded, though the amount of maths talk varied from zero to 308 utterances per hour. The main types of maths input involved naming numbers, counting, using ordinal numbers and referring to numbers in the context of time. Most of the maths talk was initiated and dominated by mothers. The results of this study underscore the ways mothers socialize mathematics with their preschoolers in interactions during meals and provide support for the use of voice recordings to study maths input in the home environment.     

Avoiders vs. Amenders: Implications for the investigation of guilt and shame during Toddlerhood?

Abstract

Recent research and theory highlights the distinctive features of shame vs. guilt, as well as the important implications of that distinction for typical and atypical behaviour regulation. Briefly, shame is characterised by withdrawal and hiding from judgemental others, and guilt by making amends–repairing and confessing. The present study was aimed at determining whether a shame-relevant and a guilt-relevant pattern of responses to a standard violation could be distinguished in toddlers.

Two-year-old children participated in a play session, during which a mishap occurred that the children appeared to have caused. Based upon whether or not children avoided the experimenter (E) after the mishap, they were dichotomised into a shame-relevant group of subjects (Avoiders) who avoid E after the mishap, are slow to make reparation, and are slow to tell E about the mishap; and a guilt-relevant group (Amenders) showing the opposite pattern. All guilt-relevant behaviours were greater for Amenders than Avoiders, and all but one shame-relevant behaviour was greater for Avoiders than for Amenders, suggesting coherence in the organisation of responses. Moreover, convergent evidence from a maternal report questionnaire indicated that in non-laboratory settings as well, Amenders manifested greater guilt relative to shame than did Avoiders. Further research is needed to determine developmental antecedents and consequences of the Avoider/Amender dichotomy.     

Gender Differences in Associations with Deviant Peer Groups: Examining Individual,Interactional, and Compositional Factors

Researchers have long known that boys are more likely to have deviant peers than are girls. Yet, little research has tried to explain why boys and girls differ in their decision to associate with deviant peers. With the salience of deviant peers well established as a robust predictor of delinquency, we address the question, are the predictors of association with deviant peers different for boys and girls? In our examination of family and community processes, individual effects, and peer group composition factors, we find that the predictors of association with deviant peers differ by gender. In addition, our findings suggest gender divergences in the causes of both deviant peer association and deviant peer pressure. We discuss the implications of our research for both theoretical development and appropriate model estimation.     

Skin cancer: Assessing perceived risk and behavioural attitudes

Abstract

Measures of attitude concerning exposure to the sun, and judgements of risk and other beliefs concerning skin cancer and four other problems (stomach cancer, deafness, AIDS and sunstroke) were obtained from a questionnaire completed by 176 university students. Subjects also estimated the incidence of each problem using one of three response formats. The highest incidence estimates were obtained when subjects were asked to guess at an absolute number, and the lowest when they used a scale which differentiated between lower frequencies, while grouping higher frequencies into a single response category. The effect of the response scale format, however, did not generalize to other ratings of personal risk. Subjects' ratings of their personal risk, compared with their peers, showed an optimistic bias over the five problems as a whole, particularly for AIDS, but not reliably so in the case of skin cancer. Optimism was inversely related to the amount of thought given to each problem. Men and women did not differ overall in their optimism regarding their own risk of skin cancer. However, differences as a function of gender and optimism were found on various behavioural attitudes. The results are discussed in relation to a tendency of disregard base-rates in subjective risk judgements, unrealistic optimism, and implications for health education.     

Neuropsychological Functioning in Children with Medium Chain Acyl Coenzyme A Dehydrogenase Deficiency (MCADD): The Impact of Early Diagnosis and Screening on Outcome

Children with medium chain acyl coenzyme A dehydrogenase deficiency (MCADD) have been reported to be at high risk for neurocognitive deficits. However this has not been systematically studied and little is known about the exact nature of neuropsychological sequelae or of the impact of early diagnosis and screening on outcome. We examined cognitive and adaptive outcome in children with MCADD (N?=?38, age range: 2 years, 2 months – 10 years, 3 months) diagnosed either through a newborn screening program (tandem mass spectrometry/MSMS) or upon clinical presentation. There was no evidence of overall intellectual impairment in either groups but there was some suggestion of poorer verbal and specific executive functioning (i.e., planning) abilities in the unscreened cohorts. Adaptive functioning was relatively intact with the exception of reduced Daily Living Skills in both our screened and unscreened groups. Early diagnosis and greater number of hospitalizations were related to higher verbal, communication, and socialization skills. Overall, our results highlight the importance of early diagnosis and management for children with MCADD.     

Determinants of coach motivation and autonomy supportive coaching behaviours

ObjectiveThe objective of the present study is to build upon the existing literature examining the coaching context and how it relates to coaches' use of autonomy-supportive interpersonal behaviours (i.e. Stebbings, Taylor, Spray, & Ntoumanis, 2012) by identifying additional environmental factors and exploring the role of coach motivation.DesignAn academic model designed by Pelletier, Seguin-Levesque, and Legault (2002) to predict teacher motivation and autonomy-supportive styles in academic settings, was adapted to the coaching context.MethodsThe influence of pressure from above (sport administrations) and pressure from below (athlete motivation) on coach motivation and autonomy-supportive coaching behaviours was tested using structural equation modeling.ResultsResults support the fit of the model in a sport context.ConclusionsPressure from above, pressure from below, and coach motivation predict coaches’ reported use of autonomy-supportive behaviours.     

Personal Construction of Family Relationships: The Relation of Commonality and Sociality to Family Satisfaction for Parents and Adolescents

This study tested the hypothesis that family members showing greater commonality (similarity) and sociality (predictive accuracy) in their construing of family relationships would display greater satisfaction with those relationships than would individuals in families whose relational construing was more discrepant and unpredictable. Forty-seven family triads participated in the study, including a mother, father, and adolescent from each family. Measures of commonality and sociality in the construction of family relationships derived from a family relationships grid were compared to measures of family structure, including the Family Cohesion and Adaptability Evaluation Scale (FACES-II) (Olson, Portner, & Bell, 1982) and the Parent-Adolescent Communication Scale (PACS) (Barnes & Olson, 1982). The findings suggest that members' perceptions of the family as emotionally close, flexible, and communicative may not represent independent aspects of the family structure, at least within the present nonclinical sample. Comparison of the family relationship grids with the FACES-H and PACS demonstrated that commonality and sociality among family members was highly related to mothers' and adolescents' family satisfaction, but was much less predictive of that of the father.
