Grandparents Affected by Parental Divorce: A Population at Risk?

When parents divorce, grandparents who have bonded with grandchildren may be affected, particularly when denied visitation. In this article the author reviews normative aspects of grand-parenthood and how grandparents are affected by parental divorce. Legal and ethical issues and counseling interventions are discussed.     

Why is 9+7 harder than 2+3? Strength and interference as explanations of the problem-size effect

In four experiments, the problem-size effect was investigated, using an alphabet-arithmetic task in which subjects verified such problems as A + 2 = C. Problem size was manipulated by varying the magnitude of the digit addend (e.g., A + 2, A + 3, and A + 4). The frequency and similarity of problems was also manipulated to determine the contribution of strength and interference, respectively. Experiment 1 manipulated frequency at low levels of practice and found that strength could account for the problem-size effect. Experiment 2 manipulated frequency at higher levels of practice, and found that strength alone could not account for the problem-size effect at asymptote. Experiment 3 manipulated frequency and similarity and found a substantial problem-size effect at asymptote, suggesting that both strength and interference contribute to the problem-size effect. Experiment 4 manipulated similarity, keeping frequency constant, and found no problem-size effect at asymptote, suggesting that interference alone is not responsible for the problem-size effect. The results are related to findings with number arithmetic.     

PREVENTION OF DEPRESSIVE SYMPTOMS IN SCHOOLCHILDREN:

Abstract— After teaching cognitive and social-problem-solving techniques designed to prevent depressive symptoms, we followed 69 fifth- and sixth-grade children at risk for depression for 2 years. We compared these children with 49 children in a matched no-treatment control group The prevention group re- ported fewer depressive symptoms through the 2-year follow-up, and moderate to severe symptoms were reduced by half. Surprisingly, the effects of the prevention program grew larger after the program was over. We suggest that psychological immunization against depression can occur by leaching cognitive and social skills to children as they enter puberty     

Sex-role identity and “being-inrelation”: The implications for women counsellors

In order to assess whether women are predisposed to make better counsellors than men, a group of 53 women and men were tested for differences in sex-role identity, and relational/autonomous qualities as defined in the the theory of the Stone Center, Massachusetts. There was no significant difference between men and women in terms of sex-role identity. Individuals lacking any clear sex-role identity showed significantly lower levels of relational/autonomous qualities. While the research did not demonstrate that women are predisposed to make better counsellors than men it indicated the following possible trends: changing sex-role identity in both men and women; the prevalence of sex-role identity biological sex as a determinant of psychological characteristics; the importance of sex-role acquisition for psychological well-being.     

Psychological determinants of decision attitude

Decision attitude — an analog of risk attitude — is the propensity to make (or avoid making) a decision: in decision aversion, a person finds it more desirable to receive through fiat the better of two options than to have a choice between them; in decision seeking, the choice is more desirable, even though it can lead to nothing better than the best option. Both decision aversion and decision seeking were found in hypothetical scenarios. Experimental manipulations and subjects' justifications point to anticipated regret, fear of blame for poor outcomes, and desire for equitable distributions as sources of decision aversion. One source of decision seeking (for self) and decision aversion (when deciding for others) appears to be the desire for the self-determination of the affected parties. We consider the implications of our results for personal choice and public policy decisions.     

Is Speech Arrest during Wada Testing a Valid Method for Determining Hemispheric Representation of Language?

Background and objective: The intracarotid amobarbital procedure, or Wada test, is the method of choice to determine hemispheric representation of language, and is routinely used in the presurgical evaluation for intractable epilepsy. Some investigators perform comprehensive language assessments, but others base language lateralization solely on speech arrest. This study sought to determine whether speech arrest alone during Wada testing provides valid data regarding language lateralization. Methods: The subjects (previously reported) were 21 patients evaluated for intractable epilepsy, who underwent language lateralization by Wada testing and functional MRI (FMRI). For each patient, language representation was determined by calculating: (1) a Wada laterality index based exclusively on speech arrest; (2) a Wada laterality index based on comprehensive language assessment; and (3) an FMRI laterality quotient. Correlation coefficients and categorical classifications were analyzed. Results: There was no significant correlation between the Wada laterality quotient derived from duration of speech arrest and either the comprehensive Wada language laterality score (r= .35,p= .12) or FMRI language laterality score (r= .32,p= .16). Categorical classification as left, right or bilateral language also showed marked discordance between speech arrest and the other two methods. Conclusion: Duration of speech arrest during Wada testing is not a valid measure of language dominance.     

A critical review of theS/L reliability index

The meaning and properties of a commonly used index of reliability, S/L,were examined critically. It was found that the index does not reflect any conventional concept of reliability. When used for an identical behavioral observation session, it is not statistically correlated with other reliability indices. Within an observation session, the standardizing measure of Lis beyond the control of the investigator. Furthermore, the reason for the choice of Las the standard is unclear. The role of chance agreement in S/Lis not known. The exact interpretation of the index depends on which observer reports L.Overall the conceptual and mathematical meaning of S/Lis dubious. It is suggested that the S/Lindex should not be used until its nature is shown to be a measure of reliability. Other approaches such as the intraclass correlations and generalizability coefficients should be used instead.The authors are indebted to Johnny Matson for his critique of an earlier version of this paper.     

Children's responses to stories with male and female characters

The sex of the main character was varied in six children's stories which were then read by fourth, sixth and eighth graders. The children answered four questions about the stories. Both boys and girls responded more positively to the questions “Would you like to be (character's name?)” and “Would you like to do the things (character's name) did?” when the main character was a male. Boys preferred stories about males, and this preference increased with grade level. A preference for stories about females was marginally significant only for the older girls. Theoretical and practical implications are discussed.
