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.     

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.     

On fineness of grain

A central job for propositions is to be the objects of the attitudes. Propositions are the things we doubt, believe and suppose. Some philosophers have thought that propositions are sets of possible worlds. But many have become convinced that such an account individuates propositions too coarsely. This raises the question of how finely propositions should be individuated. An account of how finely propositions should be individuated on which they are individuated very finely is sketched. Objections to the effect that the account individuates propositions too finely are raised and responses to the objections are provided. It is also shown that theories that try to individuate propositions less finely have serious problems.     

The Relationship Between Trajectories of Family/Cultural Stressors and Depression and Suicidal Ideation Among Substance Using Mexican-American Adults

We used an intersectional minority stress perspective to examine the association between family/cultural stress and mental health among substance-using Mexican-Americans. Employing a unique longitudinal sample of 239 socioeconomically disadvantaged, non-injecting heroin-using Mexican-Americans from San Antonio, Texas, we examined how culturally relevant stressors are related to depression and suicidal ideation. First, we identified depression and suicidal ideation prevalence rates for this disadvantaged sample. Second, we determined how cultural stress is experienced over time using stress trajectories. Third, we evaluated how family/cultural stressors and stress trajectories are related to depression and suicidal ideation outcomes. Results showed high rates of baseline depression (24 %) and suicidal ideation (30 %). We used latent class growth analysis to identify three primary stress trajectories (stable, high but decreasing, and increasing) over three time points during 1 year. We found that the increasing stressors trajectory was associated with higher rates of depression and suicidal ideation, and that stress trajectories had unique relationships with mental illness. We also showed that baseline stressors, sum stressors, and high but decreasing stressors maintained positive associations with mental illness after controlling for baseline depression. Our results highlight the importance of focusing on within-group, culturally specific stressors and addressing both operant and cumulative stressors in the study of mental health for marginalized populations and suggest the importance of early intervention in minimizing stressors.     

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.     

The health benefits of writing about positive experiences: The role of broadened cognition

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed.
