The Leftward Cradling Bias and Prosody: An Investigation of Cradling Preferences in the Deaf Community

Popular theory on the tendency to cradle an infant to the left side points to the specialization of the right hemisphere for the perception and expression of emotion. J. S. Sieratzki and B. Woll (1996) recently suggested that more emphasis be placed on the auditory modality, specifically focusing on the role of prosodic information. In this study, the direction of the lateral cradling bias in a group of profoundly deaf children, a group of deaf adults, and a control group of adults with no hearing impairment was investigated. The authors found a strong leftward cradling bias in all groups, a bias that was, if anything, stronger in the deaf participants. Given that people who are profoundly deaf, especially those who have been deaf from birth, have not been exposed to auditory prosody, the data do not support the suggestion that such prosodic information is the basis for the leftward cradling bias.     

Profiles of Chronic Illness Knowledge in a Community Sample of American Adults

The author identified profiles of chronic illness knowledge (i.e., heart disease, cancer, diabetes) in a community sample of American adults and examined the effect of sociodemographic influences on relations of illness knowledge to health practices and well-being. Participants were 181 women and 120 men who completed measures of illness knowledge, sociodemographics, personal health practices (e.g., diet, exercise, substance abuse, adaptive healthcare use), well-being (e.g., self-rated physical health, depression, social support), and perceived illness risk. Two-step cluster analyses performed on random subsets of the sample identified three levels of illness knowledge: low, medium, and high. Knowledge groups were differentiated on most measures of health practices, well-being and perceived illness risk. However, effects were substantially attenuated after controlling for differences in age and SES. Findings indicate that age and other sociodemographic factors are related not only to levels of illness knowledge but also to the application of knowledge in relation to health practices and well-being.     

Effects of Event Probability and Animateness on Children's Comprehension of Active and Passive Sentences

Thirty-six three-, four-, and five-year-old boys and girls were asked to act out, with appropriate toys, 48 sentences presented with instructions to make the toys do what E said. Sentences were designed to test the effects on comprehension of (a) event probability, (b) sentence voice, and (c) subject/object animateness. Sentences with either an animate subject and object, or an inanimate subject and object, were considered to be reversible; however, not all reversible sentences were symmetrical with respect to event probability. All main effects were significant, and performance improved with age. The significant interactions indicated that there is a difference between animateness and inanimateness in reversible sentences. The data also suggested that (a) animateness may be an important variable in children's early comprehension of speech, and (b) the traditional definition of reversibility should be modified to unconfound the effects of event probability and animateness.     

Relationships Between Need for Cognition,Knowledge, and Verbal Ability

The authors investigated the relationships between need for cognition. knowledge, and verbal ability. Participants completed scales that measured their need for cognition, verbal ability, and knowledge about people and events that occurred during the Vietnam War era. Correlational analyses showed that the participants' need for cognition scores were modestly but positively correlated with verbal ability and knowledge and that verbal ability and knowledge were also positively correlated. The correlation between need for cognition and knowledge was small but significant when verbal ability was controlled. The conclusion drawn from these results is that need for cognition contributes to the acquisition of knowledge beyond the contribution of verbal ability.     

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.
